Abstract
The invention relates to a compound anti-adhesion herniorrhaphy tablet and a preparation method thereof, clinically belonging to the field of abdominal wall defect herniorrhaphy implant medical apparatuses and manufacturing methods thereof. The compound anti-adhesion herniorrhaphy tablet comprises a polypropylene patch and a puffed polytetrafluoroethylene anti-adhesion patch, wherein the puffed polytetrafluoroethylene anti-adhesion patch is compounded on the polypropylene patch. The manufacturing method of the compound anti-adhesion herniorrhaphy tablet is characterized by comprising the following steps of: (1) hot-pressing and fusing a polypropylene reticulated weaving matter and a puffed polytetrafluoroethylene anti-adhesion membrane into a whole through a fuse machine so as to prepare a compound comprising the polypropylene patch and the puffed polytetrafluoroethylene anti-adhesion patch; and (2) cutting the compound which is hot-pressed and fused into a whole and comprises the polypropylene patch and the puffed polytetrafluoroethylene anti-adhesion patch into the anti-adhesion herniorrhaphy tablet in a preset shape through ultrasonic waves by adopting a cutter in the preset shape. The preset shape of the compound anti-adhesion herniorrhaphy tablet is a circular shape, an elliptical shape, a rectangular shape or an irregular shape.
Description
Technical field
What the present invention relates to is hernia patch of a kind of compound anti and preparation method thereof, belongs to hernia repair implant class medical apparatus and instruments of abdominal-wall defect and preparation method thereof clinically.
Background technology
Hernia is that fracture or reduction appear in the stomach wall that supports internal organs at certain position, makes that the interior internal organs of abdomen are outstanding to body surface by this fracture or weakened location, forms local lump.The method of the repairing hernia that adopts clinically is the position upper shed that takes place in hernia earlier at present, the internal organs of clamp-oning in this position are pushed back in the abdominal cavity, again will be by biocompatible materials: how the netted fabrics made from polypropylene repair that apparatuses (polypropylene sticking patch) place described opening and with it by sewing up or other mode fix in position, close this opening then.The advantage of this method is if operate suitably, and then near the distortion of bearing of the tissue the opening is few, and the corresponding tension force of receiving is also few, so be called " tension-free hernioplasty ".
(Polypropylene Mesh.Marlex, PP): formed by the polypropylene fibre braiding, be network structure, be the patching material of the abdominal-wall defect of present first-selection to the polypropylene sticking patch.In the period of 1958 to 1963, Usher writes articles the new material of having introduced a kind of Marlex50 of being called for many times, this material is compared with the metal or the nonmetallic materials of other any kinds same period, confirm all that through zoopery and clinical research it has following obvious advantage: (1) is more soft, and more tolerance is crooked and folding; (2) size is cut out with the need; (3) stimulate the proliferation of fibrous tissue effect more obvious, mesh aperture is big, is more conducive to fibrous tissue growth and passes, and is easily soaked into by connective tissue, can in early days and organize chimeric; (4) foreign body reaction is slight, and the patient does not have obvious foreign body and sense of discomfort, has very low relapse rate and complication rate.(5) more tolerance is infected, even granulation tissue still can be bred in the mesh of sticking patch in the pyogenic infection wound, does not cause that corrosion of net sheet or sinus tract form; (6) higher tensile strength is arranged; (7) be not subjected to the influence of water and most of chemical substances; (8) high temperature resistant, but scalding; (9) price is relatively cheap.
In in the past 50 years, polypropylene mesh has produced tremendous influence to surgical field, life is continued countless patients because it has been arranged, and many surgery knotty problems solve because of its application, and it has been proved to be implant most popular in the current surgical field.
However, polypropylene net also exists some problems in application: at first, when being used for stomach wall holostrome defect repairing, sticking patch will be isolated with viscera tissue, if it directly contacts with internal organs and can cause more serious abdominal adhesions, digestive tract blocks, even may corrode intestinal wall, cause intestinal fistula, cause patient's misery even need second operation.
Adhesion is to cause that in the operation that relates to peritoneum postoperative causes the main cause of post-operative complication such as chronic pelvic pain, small intestinal obstruction etc., is the result of peritoneal injury and inflammation.At the impaired position of peritoneum, thereby the permeability of blood vessel increases the infiltration of formation inflammatory, and forms fibrin matrix in the part.These fibrin matrix form the fibrin bundle between adjacent tissue.In case fibroblast slips into the fibrin bundle and causes collagen deposition, just formed clinical visible adhesion.Referring to " subfamily that merits attention-abdominal cavity surgery progress ", bang unit etc., Chinese obstetrics magazine, the 39th the 4th phase of volume of April in 2004,278-280 page or leaf.
Expanded polytetrafluoroethylsealing anti sticking patch (Expanded Polytetrafluoroethylenepatch, e-PTFE): this expanded polytetrafluoroethylsealing anti sticking patch is than polypropylene sticking patch softness, be difficult for when contacting with abdominal viscera forming adhesion, caused inflammatory reaction is also the lightest; But expanded polytetrafluoroethylsealing does not have support force, the easier secondary recurrence of stomach wall damaged part.Expanded polytetrafluoroethylsealing anti sticking patch allows antibacterial to pass through, and phagocyte can not can not be grown into by, tissue, so it can not tolerate and infect and pollute, the wound that can not be used to pollute will take out in case infect sticking patch, otherwise wound is difficult to heal.Expanded polytetrafluoroethylsealing anti sticking patch is used for Treatment of Recurrent Inguinal Hernia at present more; Because of directly contacting with internal organs, it causes adhesion hardly, so also incisional hernia that is used for more; Be used for the damaged little young inguinal hernia patient of hernia ring, can avoid some complication such as the adhesion of postoperative spermatic cord, painful ejaculation discomfort.
Summary of the invention
The present invention seeks at weak point, hernia patch of a kind of compound anti and preparation method thereof is provided, adopt polypropylene sticking patch and expanded polytetrafluoroethylsealing anti patching material to constitute, characteristics are to have taken into account the advantage that the polypropylene sticking patch does not have tension force and expanded polytetrafluoroethylsealing anti patching material anti, promptly not having tension force polypropylene net tissue grows into, implant the back firmly, and the expanded polytetrafluoroethylsealing material can be put into intraperitoneal and contacts with internal organs, and anti effect is preferably arranged in the stomach wall growth.
