Abstract
The utility model relates to an introducer of a laparoscopic surgery puncture outfit. The introducer of the laparoscopic surgery puncture outfit comprises an external introducing tube (12) and an internal push rod (11), wherein the external introducing tube (12) is provide with a horn-shaped upper opening, the lower end portion of the external introducing tube (12) is an asymmetrical slope-shaped opening, and a superincumbent guiding groove (15) is arranged on the external wall of the external introducing tube (12). The novel designed instrument is similar to an injection syringe, can complete the necessary emplacing action requirement simply, conveniently and fast, and can meet a higher clinical requirement.
Description
Technical field
This utility model relates to a kind of laparoscopic surgery assistive device, and especially a kind of conductor that can help the laparoscopic surgery perforator to enter fast the laparoscopic surgery perforator in abdominal cavity belongs to medical mechanical domain.
Background technology
Use the micro-wound surgical operation of laparoscopic technique also day by day to be promoted at home use, hospitals more both domestic and external use single hole or porous laparoscopic technique to implement through umbilicus single hole mirror cholecystectomy, appendectomy, Hepatobiliary cystadenoma Tomography excision etc.In operation process, these are opened and must settle an abdominal cavity passage on the little otch of 5～12 millimeters of abdominal part different parts, diameter, be convenient to insert pick-up lens and various special operating theater instruments, to insert the image transmitting of the captured various internal organs of intraperitoneal of Intraabdominal photographic head to telescreen, the surgeon is by observing image, operates to finish operation with various operating theater instruments external.
Have the multi-channel single-hole laparoscopic surgery puncture outfit of utility model now in use, the clinician adopts dual mode.
Mode one: the doctor the inner sleeve parts of multi-channel single-hole laparoscopic surgery puncture outfit pinch flat after, fill in the otch of umbilical part, finish the action request that is placed in patient's abdominal part.
Mode two: the doctor uses the pliers such as sponge holding forceps to clamp the inner sleeve parts of multi-channel single-hole laparoscopic surgery puncture outfit, then fills in the otch of umbilical part, finishes the action request that is placed in patient's abdominal part.
Although above dual mode can be applicable to the situation of the overwhelming majority, when the build overweight people occurring, when especially reaching the fat situation of severe, above-mentioned dual mode has all seemed difficulty.Its reason is that this class soft-fat type patient's abdominal part has a large amount of fat, and the degree of depth of umbilical notch cut obviously increases, and having caused the inner sleeve of multi-channel single-hole laparoscopic surgery puncture outfit to enter the abdominal part stroke obviously increases.In practical probation and use procedure, user has proposed a Secretary, that is: a kind of device is used in hope, can be placed on patient's abdominal part to multi-channel single-hole laparoscopic surgery puncture outfit more easily, thereby reduction operating difficulty, shorten operating time, obtain better clinical result of use.
The utility model content
The purpose of this utility model: aim to provide a kind of passage single-hole laparoscopic puncture outfit that can help efficiently and easily and insert the interior auxiliary device of 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, the technical solution of the utility model is as follows:
The conductor of this laparoscopic surgery perforator, consisted of by outer guide wire 12 and inner push-rod 11, described outer guide wire 12 has a tubaeform upper shed, and the bottom is asymmetric domatic opening, and is equipped with a top-down guide groove 15 at described outer guide wire 12 outer walls.
Described guide groove 15 tops are tapered inlet, and bottom notch and outer guide wire 12 domatic open pointed tip positions are symmetrical.
Described outer guide wire 12 is metal tube or is 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, easy to operate characteristics, can be pushed to patient's abdominal part to multi-channel single-hole laparoscopic surgery puncture outfit quickly and easily, finish the action request of settling multi-channel single-hole laparoscopic surgery puncture outfit, 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 this utility model below in conjunction with Figure of description, and provide embodiment of the present utility model.
The conductor of this laparoscopic surgery perforator as shown in Figure 1, 2, consisted of by outer guide wire 12 and inner push-rod 11, described outer guide wire 12 has a tubaeform upper shed, and the bottom is asymmetric domatic opening, and is equipped with a top-down guide groove 15 at described outer guide wire 12 outer walls.
Described guide groove 15 tops are tapered inlet, and bottom notch and outer guide wire 12 domatic open pointed tip positions are symmetrical.
Described outer guide wire 12 is metal tube or is 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 hydrophilic coating, also can be hydrophobic coating; Perhaps there is not lubricant coating.
During use, first the inner sleeve 21 of multi-channel single-hole laparoscopic surgery puncture outfit 2 pinch in advance flat, be tucked in the horn opening on this guide 1 top, make it enter guide groove 15.Entered subsequently the inner sleeve 21 of the multi-channel single-hole laparoscopic surgery puncture outfit 2 of outer catheter 12 inner chambers from guide groove 15 top pushing tows with inner push-rod 11, whole multi-channel single-hole laparoscopic surgery puncture outfit 2 is continued in guide groove 15 interior downward operations, finish the arrangement action request until whole multi-channel single-hole laparoscopic surgery puncture outfit 2 last disengaging guide grooves 15 enter the abdominal cavity.If it is not in place that the surgeon cuts the operative incision in abdominal cavity at first, the cutting edge at conductor tip can help again appropriateness expansion otch so, makes it to reach the required size dimension of operation.
Simultaneously, because guide wire 12 inwalls apply lubricant coating outside, therefore make inner push-rod 11 and outer guide wire 12 cooperatively interact smooth.The frictional force that this will help to reduce when pushing multi-channel single-hole laparoscopic surgery puncture outfit has promoted the propelling movement smoothness.
Show by the reality use: this newly-designed apparatus syringe-like, can finish simply and easily required arrangement action request, satisfy higher clinical demand.
With use syringe guide 1 multi-channel single-hole laparoscopic surgery puncture outfit 2 as example, be divided into two large 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 multi-channel single-hole laparoscopic surgery puncture outfit.
This utility model structure is small and exquisite, easy to operate, can be widely used in also can be used for the fields such as prostatectomy, adrenalectomy, orchiopexy, orchiectomy, ureterolithotomy, the nephrectomy, pyeloplasty through umbilicus single-hole laparoscopic cholecystectomy, appendectomy, stomach fistulation, splenectomy, fully outside Total Extraperitoneal Repair.
