Abstract
The invention relates to an introducer for a laparoscopic surgery puncture outfit, which consists of an outer guide pipe (12) and an inner push rod (11), wherein the outer guide pipe (12) is provided with an upper horn-shaped opening; the lower end part of the outer guide pipe (12) is an asymmetric slope-shaped opening; and the outer wall of the outer guide pipe (12) is provided with a guide slot (15) from top to bottom. According to the newly designed syringe-like introducer, the required installation action requirement can be simply and conveniently finished so as to satisfy a higher clinic requirement.
Description
Technical field
The present invention relates to a kind of laparoscopic surgery assistive device, especially a kind of conductor that can help the laparoscopic surgery perforator to get into the laparoscopic surgery perforator in abdominal cavity fast belongs to medical mechanical domain.
Background technology
The micro-wound surgical operation of utilization laparoscopic technique is also promoted the use of at home day by day, and hospitals more both domestic and external use single hole or porous laparoscopic technique to implement through umbilicus single hole mirror cholecystectomy, appendectomy, stones in intrahepatic bile duct cystadenoma excision or the like.In operation process; These are opened and on the little otch of 5~12 millimeters of abdominal part different parts, diameter, must settle an abdominal cavity passage; Be convenient to insert pick-up lens and various special operating theater instruments; The image that inserts the captured various internal organs of intraperitoneal of Intraabdominal photographic head is transferred on the telescreen, and the surgeon accomplishes operation with various operating theater instruments external the operation through observing image.
The multichannel single-hole laparoscopic surgery perforator of existing invention in use, the clinician adopts dual mode.
Mode one: the doctor the inner sleeve parts of multichannel single-hole laparoscopic surgery perforator pinch flat after, fill in the otch of umbilical part, accomplish the action request that is placed in patient's abdominal part.
Mode two: the doctor uses pliers such as sponge holding forceps to clamp the inner sleeve parts of multichannel single-hole laparoscopic surgery perforator, then fills in the otch of umbilical part, accomplishes the action request that is placed in patient's abdominal part.
Though above dual mode can be applicable to the situation of the overwhelming majority, when the build overweight people occurring, when especially reaching severe obesity situation, above-mentioned dual mode has all seemed difficulty.Its reason is that this type soft-fat type patient's abdominal part has great amount of fat, and the degree of depth of umbilical notch cut obviously increases, and has caused the inner sleeve entering abdominal part stroke of multichannel single-hole laparoscopic surgery perforator obviously to increase.In practical probation and use; User has proposed a new requirement; That is: hope to use a kind of device, can be placed on patient's abdominal part to multichannel single-hole laparoscopic surgery perforator more easily, thereby reduce operating difficulty; Shorten operating time, obtain better clinical result of use.
Summary of the invention
The object of the invention: aim to provide a kind of passage single-hole laparoscopic surgery perforator that can help efficiently and easily and insert the auxiliary device in the corrective surgery opening, both shortened operating time, can alleviate the patient suffering again simultaneously.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following:
The conductor of this laparoscopic surgery perforator; Constitute with inner push-rod 11 by outer guide wire 12; Described outer guide wire 12 has a tubaeform upper shed, and the bottom is asymmetric domatic opening, and outside said, is equipped with a top-down guide groove 15 on guide wire 12 outer walls.
Described guide groove 15 tops are tapered inlet, bottom notch and outer guide wire 12 domatic open pointed tip positions symmetry.
Described outer guide wire 12 is the metal body, or for nonmetal body.
Described outer guide wire 12 bottom domatic openings are the cutting edge shape.
Described outer guide wire 12 inwalls apply lubricant coating.
This syringe guide according to above technical scheme proposition; Not only have simple in structure; Convenience operation can be pushed to patient's abdominal part to multichannel single-hole laparoscopic surgery perforator quickly and easily, accomplishes the action request of settling multichannel single-hole laparoscopic surgery perforator; Reduced the arrangement difficulity of the movment, not only can shorten operating time, but also can alleviate the patient suffering.

The specific embodiment
Further set forth the present invention below in conjunction with Figure of description, and provide embodiments of the invention.
Conductor like Fig. 1, this laparoscopic surgery perforator shown in 2; Constitute with inner push-rod 11 by outer guide wire 12; Described outer guide wire 12 has a tubaeform upper shed, and the bottom is asymmetric domatic opening, and outside said, is equipped with a top-down guide groove 15 on guide wire 12 outer walls.
Described guide groove 15 tops are tapered inlet, bottom notch and outer guide wire 12 domatic open pointed tip positions symmetry.
Described outer guide wire 12 is the metal body, or for nonmetal body.
Described outer guide wire 12 bottom domatic openings are the cutting edge shape.
Described outer guide wire 12 inwalls apply lubricant coating.
Described upper shed can be triangle, circle, ellipse.
The outer guide wire inwall of E, described syringe guide has lubricant coating, and coating can be a hydrophilic coating, also can be hydrophobic coating; Perhaps there is not lubricant coating.
During use, earlier the inner sleeve 21 of multichannel single-hole laparoscopic surgery perforator 2 pinch in advance flat, be tucked in the horn opening on this guide 1 top, make its entering guide groove 15.Got into the inner sleeve 21 of the multichannel single-hole laparoscopic surgery perforator 2 of outer catheter 12 inner chambers subsequently from guide groove 15 top pushing tows with inner push-rod 11; Make whole multichannel single-hole laparoscopic surgery perforator 2 continue operation downwards in guide groove 15, accomplish until whole multichannel single-hole laparoscopic surgery perforator 2 last disengaging guide grooves 15 entering abdominal cavities and settle action request.If it is not in place that the surgeon cuts the operative incision in abdominal cavity at first, the most advanced and sophisticated cutting edge of conductor can help appropriateness expansion otch once more so, makes it to reach the required size dimension of operation.
Simultaneously, because guide wire 12 inwalls apply lubricant coating outside, inner push-rod 11 and outer guide wire 12 are cooperatively interacted along sliding.The frictional force that this will help to reduce when pushing multichannel single-hole laparoscopic surgery perforator has promoted the propelling movement smoothness.
Show through the reality use: this newly-designed apparatus syringe-like, can accomplish required arrangement action request simply and easily, satisfy higher clinical demand.
To use syringe guide 1 to be example to multichannel single-hole laparoscopic surgery perforator 2, be divided into two big steps:
During practical application, outer guide wire 12 inwalls of described syringe guide can be coated with lubricant coating, can reduce inner sleeve 21 running resistance in the guide wire 12 outside syringe guide of multichannel single-hole laparoscopic surgery perforator.
Structure of the present invention is small and exquisite; Easy to operate; Can be widely used in through umbilicus single-hole laparoscopic cholecystectomy, appendectomy, stomach fistulation, splenectomy, outside peritoneum, outside the sticking patch implantation, also can be used for fields such as prostatectomy, adrenalectomy, orchiopexy, orchiectomy, ureterolithotomy, the nephrectomy, pyeloplasty fully.
