Description

The prosthetic device that the vaginal surgery reparation that damages because of pelvic organ prolapse is used

The present invention relates to the vaginal wall that damages because of one or more pelvic organ prolapse the surgical repair method, variously be used for this operating repair materials and device, and be suitable for the workbox that the surgeon uses when the women of pelvic organ prolapse disease is suffered from treatment.

Background technology

In Australia, just there is 1 accepting the pelvic organ prolapse surgical operation among similar per 4 women.And other many national ratios are higher.There are every year 200,000 women to accept the pelvic organ prolapse operation approximately in the U.S..Pelvic organ prolapse is generally relevant towards introitus vaginae sagging (or outstanding outside in opposite extreme situations) along vagina with uterus, bladder or rectum.Advanced age women or the several children of sick mistake the easier trouble pelvic organ prolapse of women.

Traditional vagina operation mortality is higher, between 30-40%.Resemble abdominal part rumpbone colpopexy, the transvaginal sacrospinous ligament is fixed and abdominal cavity rumpbone colpopexy is so complicated and meticulous abdominal part, vagina and abdominal cavity therapeutic process developed into and reduce the prolapsus risk of relapse.These therapeutic processes need very high surgical technic level, have only a small amount of specialist to implement, thereby also only are applicable to a small amount of patient but regrettably.Relevant various at present at the visible Boyles SH. of the operation details of usefulness, Weber AM, " the Procedures for pelvicorgan prolapse in the United States " of Meyn L, 1979-1997, AmericanJournal of Obstetric Gynaecology 2003,188; 108-115.

There is a kind of trend to use reinforcement material to support the vaginal wall that damages because of prolapsus in recent years.Repair materials such as donor fascia lata, Corii Sus domestica and all kinds of synthetic nets is utilized, and has obtained blended success.These materials generally are placed under one or more vaginal walls and are sewed up this position.The applicant has realized that at present very undesirable at the synthetic net of usefulness, because they mainly deviate to design for stomach wall before treating, edeoptosis is in general too heavy for treating.Some nets that use can cause some long-standing problems at present, and it comprises that sexual anhedonia, net advance vaginal cavity erosion (this need perform the operation and remedy) and net shrinks the pain that causes.

An object of the present invention is to provide a kind of surgical procedures that is suitable for treating multi-form pelvic organ prolapse of simplification.Be suitable for being used in repair materials and the device that vagina is repaired when also having a purpose to provide the treatment pelvic organ prolapse.

Summary of the invention

Provide a kind of method to repair the vaginal wall that damages because of one or more pelvic organ prolapse according to a first aspect of the invention, described method comprises:

(a) mobile vagina epithelium leaves the lower floor's fascia to small part of impaired vaginal wall;

(b) on the fascia that exposes, locate repair materials;

(c) on repair materials and fascia, retighten vagina epithelium; After this

(d) intra-vaginal splint is placed into vagina.

To the explanation of the inventive method and refer to its size at the used phrase " intra-vaginal splint " in its elsewhere of this description (comprising claims) and can be placed on the mobility that can reduce vaginal wall after in a single day any device of vaginal cavity and its be placed on vaginal cavity.

The epifascial repair materials that is placed on exposure preferably is attached on the fascia.This attachment means is normally sewed up, but also can utilize additive method, for example adopts binding agent or surgery bail to realize.

In some prolapsus cases, only require and repair one of vaginal wall.Yet in many prolapsus cases, what require reparation is the vagina front and rear wall.In this case, it is unimportant to repair the antetheca rear wall earlier, though it is more convenient usually to repair antetheca earlier.Therefore,,, repair materials is being placed on the vaginal wall fascia of front and back, and the vagina epithelium of two respective wall is after being retightened on repair materials and the fascia, in intravaginal location intra-vaginal splint if repair former and later two vaginal walls according to the present invention.

Therefore, in the case that former and later two vaginal walls all need be repaired, preferable methods of the present invention comprises the following steps:

(a) mobile vagina epithelium leaves the lower floor's fascia to small part of provagina wall;

(b) location first repair materials on the provagina wall fascia that exposes;

(c) on described first repair materials and provagina wall fascia, retighten vagina epithelium;

(d) mobile vagina epithelium leaves the lower floor's fascia to small part of back vaginal wall;

(e) location second repair materials on the back vaginal wall fascia that exposes;

(f) on described two repair materials and back vaginal wall fascia, retighten vagina epithelium; After this

(g) intra-vaginal splint is placed into vagina.

The preferably vagina operation of performing the operation.

No matter be to repair one or two vaginal walls, in most cases, after repair materials has been merged in the vaginal wall tissue, should take down intra-vaginal splint.Intra-vaginal splint is being preferably at least 3 week of reservation on the intravaginal position after the insertion.The most preferably intra-vaginal splint is taking down between 4 to 6 weeks after the insertion.

When repairing the provagina wall, epifascial vagina epithelium preferably moves by otch and side direction cutting, preferably does cutting towards the arc tendon fascia pelvis on (or approaching) both sides.If only repair the provagina wall, preferably the sacrospinous ligament towards both sides continues cutting.If the front and back vaginal wall all need be repaired, so preferably by every limit arc tendon fascia pelvis and enter the other space of vagina and continue cutting antetheca epithelium, so that can touch the inboard of pubis.Be placed on the fascia of exposure at first repair materials before, fascia may be wrinkling because of stitching.

Equally, lower floor's fascia (recto-vaginal septum fascia) may be wrinkling during vaginal wall after reparation.Vagina epithelium on the rear wall preferably come to move by otch and cutting, and side direction is to the anus elevator on every limit and be positioned at the top of vagina, in the rectal columns of passing through both sides and on the side direction and forward direction of every limit sacrospinous ligament.

When implementing aforesaid surgical method, can use any traditional repair materials that is used for the treatment of pelvic organ prolapse that is using at present.Therefore, may use xenograft material, allograft skin or the autotransplantation skin such as Corii Sus domestica or be suitable for strengthening the synthetic material of vaginal wall.

But, the preferably synthetic net of the repair materials that uses in the inventive method.In particular, preferably repair materials has the following characteristic that is had when explanation is newly synthesized net.

The applicant has been found that and will use intra-vaginal splint can improve wound healing after the repair materials location and reduce the surgical operation mortality.The intra-vaginal splint of using in said method preferably has the structure and the characteristic of new intra-vaginal splint described below.

According to a further aspect in the invention, provide a kind of synthetic net of flexibility to be used to repair the vaginal wall that damages because of one or more pelvic organ prolapse, described synthetic net comprises in a large number the opening of the line limited boundary of being made by non-woven polymeric materials, wherein the joint between the homologous lines is very close to each other, and wherein the aperture area of most nets less than 15 square millimeters.

The area of all mesh openings is preferably all less than 15 square millimeters.The area of the opening size of best most mesh openings is less than 10 square millimeters.

Net can have any suitable shape, but generally has central body portion and two vertical lateral sections.In most preferred embodiment, the opening size of net central body portion is bigger than the opening size in vertical lateral section.Each aperture area on the best netted object is less than 10 square millimeters, and each aperture area of net lateral section is less than 5 square millimeters.Preferably the width of lateral section is at least 3 millimeters.The width of lateral section is preferably between 4 to 8 millimeters.

Light and gentle net is very desirable.The weight of net is preferably less than 0.0080 gram/square centimeter.Preferably its weight is between 0.0020 to 0.0050 gram/square centimeter.Can use the biocompatible polymeric material of any flexibility.Preferred polymeric material is a polypropylene, and polypropylene fibre is monfil preferably.

The joint of net of the present invention between homologous lines do not comprise any gap.After net being positioned under the vagina epithelium, importantly make in the net or net around bacterial growth reduce to minimum.Therefore, the net right and wrong are woven, and are alternate, and it can be made by used polymeric material sheet is stamped out profile, perhaps optionally, contiguous line connected in the mode that can not the joint between homologous lines produces the gap.Can accomplish this point by bonding or welding most convenient.

The provagina wall is repaired, and synthetic net of the present invention can roughly be done ovalisation, the back vaginal wall is repaired it can roughly do in echelon, has two to make progress and the adjutage to extend away from the angle of two lateral sections of net.In a particularly preferred embodiment, oval net (being used to repair the provagina wall) comprises two lateral arms, and the mid portion from the arbitrary lateral section of net from each side extends out.

When using the oval net that lateral arms is preferably arranged to repair the provagina wall, used net is placed on the pubocervical fascia in the said method, and its each lateral arms is placed in the past that vaginal wall incision extends in the pipeline of other space of vagina and pubis inboard.

The above-mentioned preferred net of vaginal wall is positioned at the recto-vaginal septum fascia after being used in the methods of the invention repair, and each adjutage is put into the pipeline that extends to sacrospinous ligament from the back vaginal wall incision.Net is placed on the fascia, and back vaginal wall epithelium is closed then also is fixed on the net again, to finish reparation.

No matter whether repair materials is preferably aforesaid synthetic net or other suitable materials, repair materials all preferably is attached on the corresponding fascia by the sutures of using side with repair materials to be attached to the fascia wall.

With reference to Fig. 1, it illustrates vagina (1) and the provagina wall of opening (2).Vaginal wall (2) is covered by epithelial layer (3).Fig. 1 shows the situation of incision vagina epithelium.In case carried out initial cutting along vagina epithelium layer (3), as shown in Figure 2, strip off epithelium (3) also keeps leaving fascia (6).Carry out the side direction cutting, pass the arc tendon fascia pelvis on both sides then, and enter the other space of vagina on every limit.In case epithelium (3) has moved away the fascia wall, the wrinkling probably (not shown) of fascia (6).Then net (7) is placed on damaged (4) of fascia (6) of exposure.Simultaneously each of net (7) extends laterally arm (7a 7b) is placed into the other space of vagina of homonymy, and (7a 7b) touches the inside of pubis so that extend laterally arm.Net shown in Figure 3 (7) can be seen more in detail at Figure 10.Net (7) has central body portion (8), and its shape is roughly ellipse, and have the top arrive the bottom vertical lateral section (9 and 10), described lateral section integrate with extend laterally arm (7a, 7b).In most cases the size of net is about 50 millimeters, and its wide (extending laterally except the arm) between about 30-40 millimeter, this is enough.(7a 7b) has 30 millimeters long, 20 mm wides as a rule approximately to extend laterally arm.Be understandable that the size of net will depend on the size that is repaired vaginal wall basically.Net shown in Fig. 3 and 10 is made by polypropylene.In the central body portion (8) of net (7), the area of each opening is approximately 9 square millimeters (3 millimeters * 3 millimeters).(7a, opening size 7b) are approximately 3 square millimeters (1 millimeter * 3 millimeters) for lateral section (9 and 10) and adjutage.Net is made by the monofilament polypropylene, is bonding or welding net, heavily about 0.003 gram/square centimeter.In case net (7) is placed on the fascia (6) of provagina wall (2), it is attached on the fascia (6) by sutures (11).Then unnecessary vagina epithelium is pruned, by the closed provagina wall of sutures (12), as shown in Figure 4.

Repair back vaginal wall such as Fig. 5 to shown in Figure 8.Back vaginal wall (13) shown in Figure 5 be the back vaginal wall epithelium (14) in position.As shown in Figure 5, for epithelium (14) is moved away lower floor's fascia (15), carried out rip cutting.Fig. 6 shows the damaged 15a on the fascia 15.Anus elevator on the every relatively limit of side direction is cut.This is also shown in Fig. 6.In the top of vagina part, the sacrospinous ligament of rectal columns towards every limit that passes both sides in side direction and forward direction continues cutting.This has formed the bilateral pipeline from the back vaginal wall incision to each sacrospinous ligament.The wrinkling probably (not shown) of recto-vaginal septum fascia.The net (16) that is designed for the shaping in advance of repairing the back vaginal wall is as Fig. 7 and shown in Figure 9.It is placed on the recto-vaginal septum fascia (15), and each adjutage (17,18) is placed into from the back vaginal wall incision in the pipeline of sacrospinous ligament.Being positioned among Figure 19 of net (16) is more clear, and it shows the position of its relative sacrospinous ligament (33), rectum (34) and vagina (35).With reference to Fig. 9, can see that being designed for the net of shaping in advance (16) of repairing back vaginal wall (13) has central body portion (19) and vertical lateral section (20) and (21).The width of this net is from about 3 centimetres of 11 centimetres of variations to the top of bottom.The width at the top (22) of the central body portion (19) of net (16) is about 6 centimetres.About 7 centimetres of the midline length of net (16), each adjutage (17,18) are about 5 centimetres, wide about 1.5 centimetres.Net (16) is also made by the monofilament polypropylene, is bonding or welding net, heavily about 0.0030 gram/square centimeter.The area of the opening size of each opening of the central body portion of net (19) is about 9 square millimeters (3 * 3 millimeters), and vertically the aperture area of lateral section (20,21) is about 3 square millimeters (1 * 3 millimeters).

In case net (16) is placed on the fascia, it will be anchored on the appropriate location, by sutures (23) as shown in Figure 7.As shown in Figure 8, unnecessary back vaginal wall epithelium (14) can be pruned, and then vagina epithelium (14) is retightened on net (16).

Used the workbox of big minispread intra-vaginal splint as shown in figure 18 in this.The surgeon selects the suitably clamping plate of size from the workbox.In case determined the just size of intra-vaginal splint by the model clamping plate in the tool using case, just this intra-vaginal splint inserted vagina and sewed up the position with anti-extrusion.Can clearly see this point by Figure 20, wherein vaginal splint (36) has been positioned in the vagina (35).Intra-vaginal splint shown in Figure 11 at one end is useful on the aperture (33) that holds sutures.

Figure 11 to 17 shows preferred intra-vaginal splint.It comprises side arm (24) and (25) of longitudinal extension, and connector (26) and (27).(this part is extended about 20 millimeters from connector (26)) preferably tilts about 10 ° from the remainder (31) of clamping plate in the bottom of clamping plate (30).This can clearly see on Figure 12 and 13.The core of clamping plate is by silicone resin film (32) closure.This film has double-deck skin in one embodiment, and inflatable, as shown in figure 16.Expand and can realize by pipe 32a by fluidic film, this pipe provides spatial fluid passage between each layer 32b that enter film and the 32c.This shows in Figure 16 (perspective view) and Figure 17 (side view).

Intra-vaginal splint is preferably in the time that intravaginal kept for 4 weeks.In case spent this section period, can take down clamping plate, synthetic at this moment net should be incorporated in each corresponding vaginal wall tissue.

Clinical test results

Method of the present invention has been carried out clinical trial to 49 women.These women's mean age is 57.7 years old (from 34-79 year), on average produces several 2.8 (the scope 1-6) of children.22 women (45%) once accepted previous uterectomy, and 21 women (43%) accepted once the surgical procedures at pelvic organ prolapse at least.9 women (18%) once accepted the operation of treatment stress incontinence, and 5 women (10.2%) accepted twice or repeatedly treated the operation of pelvic organ prolapse.

The operation that these 49 women are carried out sees following table 1 for details.5 women have only been repaired provagina with synthetic net, 32 women have only been repaired back vagina with synthetic net, vagina reparation before and after 12 women have been carried out with synthetic net.

When only repairing provagina with net, vagina epithelium is stripped from lower floor's fascia.Continue the side direction cutting then up to arriving each arc tendon fascia pelvis.Proceed the cutting of top and side direction then up to arriving every sacrospinous ligament.Place the synthetic net of a Y shape on fascia, the adjutage of net is put into the pipeline that forms on the sacrospinous ligament because of cutting to.Sutures is not placed in the sacrospinous ligament.Net is loosely placed and is fixed on the appropriate location with two to three sutures, and net is fixed on the fascia.Remove unnecessary vagina epithelium, the epithelium on the closed then net.

When strengthening back vagina reparation with net, vagina epithelium is stripped from lower floor's fascia.On every limit, continue the side direction cutting up to the anus elevator.Continue the cutting of top and side direction then and pass rectal columns up to every sacrospinous ligament.Place a Y shape net on fascia, the adjutage of net is put into the pipeline that forms on the sacrospinous ligament because of cutting to, so that net and each sacrospinous ligament adjacency.Sutures is not put into sacrospinous ligament.Remove unnecessary epithelium, the back vaginal wall epithelium on the closed then net.

When strengthening the front and back vaginal wall with net, as mentioned above, net is placed on the vaginal wall of back subcutaneous.The technology of subcutaneous placement net and above-mentioned technology are different on the pro-vaginal wall.Pass each arc tendon fascia pelvis and continue the side direction cutting up to entering the other space of left and right sides vagina, so that can touch the inside of pubis.Before do not cut on the sacrospinous ligament.Cut a cross net and be placed on the fascia, its adjutage is put into the other space of each vagina, so that the inner abutment of net and every limit pubis.

All patients have accepted the prevention antibiotherapy, and it can continue 48 hours after operation.Usually every patient has been used Ke Sai (Clexane) and lasted till patient discharge always.

Finishing the operation back has placed big or small suitable intra-vaginal splint and it has been sewed up the appropriate location in case move in intravaginal.Vaginal splint is made by medical grade silicone, has used 3 kinds of sizes so that big minispread.Behind the patient discharge, carry out first time check the 4th week, taking down intra-vaginal splint at the doctor's.The sutures that in 4 time-of-weeks vaginal splint is remained on the appropriate location is decomposed.

The result

Patient checks to take down vaginal splint in 4 weeks after operation.There is not a women to occur the further symptom or the nbjective symptom of 2 grades (Baden-Walker classification) or more high-grade pelvic organ prolapse again.Do not have to take place in the bigger operation or postoperative complication.

Discuss

After pelvic organ prolapse operation, when patient moves or coughs, vomits and strains because of the intestinal emptying, repair and cause intra-abdominal pressure to rise easily.Might the intra-abdominal pressure rising vagina reparation healing be can have influence on unfriendly, thereby operative failure and recurrence prolapsus caused.After operation,, can reduce operating risk of failure of pelvic organ prolapse and risk of recurrence by strengthening the vagina reparation with net and supporting vagina 4 time-of-weeks with fixation device.Net is merged into bodily tissue at the 3rd periderm.But the vaginal splint device not only can support vagina tissue but also the position of support net thing after operation.Be merged into bodily tissue by support up to it, can avoid sutures is put into sacrospinous ligament or the other space of vagina the net position.This is oversimplified operation, has avoided concrete and has placed contingent complication because of the sutures in these structures.

This operation technique is done very simple for general gynaecologist, urinary system gynaecologist and urologist.

Table 1 carries out the details of pelvic organ prolapse operation

The present invention includes the simplification operation technique that treatment pelvic organ prolapse and vagina are repaired.Described net was compared with the net that is using with the past and is more suitable for vaginal surgery, and described surgical method can make the surgeon can treat prolapsus by complicated abdominal part, vagina or laparoscopic procedure.
