Description

A kind of visible ring-removing forceps

Technical field:

What the present invention relates to is a kind of medical surgical instrument, especially a kind of visible ring-removing forceps that is used to extract intrauterine contraceptive loop.

Background technology:

In the prior art, the operation of known excision intrauterine contraceptive loop is the device for taking out of intrauterine contraceptive device (IUD) tool that adopts a kind of buckle, this device for taking out of intrauterine contraceptive device (IUD), can not direct observation intrauterine contraceptive loop position and the ambient conditions at intrauterine contraceptive loop place, when undergoing surgery, can only armrest art apparatus or the auxiliary facilities position of seeking intrauterine contraceptive loop, but still can not understand the situation around the intrauterine contraceptive loop, therefore, when getting ring, very easily cause pulling or scratch to surrounding tissue, cause unnecessary misery to the operation receiveing person, this is the existing in prior technology weak point.

Summary of the invention:

Purpose of the present invention, be exactly at the existing in prior technology deficiency, and providing a kind of visible ring-removing forceps technical scheme, this scheme to adopt inner chamber that the sight glass cover of sight glass service aisle is arranged, this just can directly observe the position and the surrounding of intrauterine contraceptive loop with sight glass, avoided blindly operation, add again that to get ring be to clamp intrauterine contraceptive loop by binding clip, rather than hook intrauterine contraceptive loop, therefore by hook, can avoid injury that surrounding tissue is caused, reduce operation receiveing person's misery.

This programme is realized by following technical measures: the characteristics of this programme are the pincers seats that has an energy to be connected with sight glass, on the pincers seat, be fixed with the sight glass cover that inner chamber is the sight glass service aisle, put at sight glass and to be fixed with leader casing, the inner chamber of leader casing has and can axially come and go the binding clip guide rod that moves along leader casing, one end of this binding clip guide rod is fixedlyed connected with the slide block in the pincers seat, the other end of binding clip guide rod and two binding clip folding guide cards are hinged, two binding clip folding guide cards respectively with two binding clips on binding clip brace cross-articulation, described slide block is hinged with an end of slide block pull bar again, the other end of slide block pull bar and binding clip operating grip are hinged, this binding clip operating grip is connected with the pincers seat by arm pivot post, the top is fixed with the binding clip back-up block on described leader casing, be fixed with the binding clip rotating shaft on the binding clip back-up block, the binding clip brace on this binding clip rotating shaft and two binding clips is hinged.The concrete characteristics of this programme also have, and on described slide block sliver are arranged, and being has the guide groove that matches with sliver on the pincers seat inwall of slide block contact.The lock sleeve that is connected with sight glass is arranged at the bottom at the pincers seat.There is the isolation eyeglass on the top on described sight glass cover.In described binding clip inboard the binding clip peephole is arranged.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, the pincers seat that has an energy to be connected with sight glass, on the pincers seat, be fixed with the sight glass cover that inner chamber is the sight glass service aisle, put at sight glass and to be fixed with leader casing, the inner chamber of leader casing has and can axially come and go the binding clip guide rod that moves along leader casing, one end of this binding clip guide rod is fixedlyed connected with the slide block in the pincers seat, the other end of binding clip guide rod and two binding clip folding guide cards are hinged, two binding clip folding guide cards respectively with two binding clips on binding clip brace cross-articulation, described slide block is hinged with an end of slide block pull bar again, the other end of slide block pull bar and binding clip operating grip are hinged, this binding clip operating grip is connected with the pincers seat by arm pivot post, the top is fixed with the binding clip back-up block on described leader casing, be fixed with the binding clip rotating shaft on the binding clip back-up block, the binding clip brace on this binding clip rotating shaft and two binding clips is hinged.This structure is the sight glass cover of sight glass service aisle because inner chamber is arranged, and just can be used with sight glass when operation, makes this programme have position and the surrounding that can directly observe intrauterine contraceptive loop with sight glass, has avoided blindly operation.Add again that to get ring be that slide block drives the opening and closing that the binding clip guide rod moves the control binding clip again, clamps intrauterine contraceptive loop with binding clip and takes out by the moving of binding clip operating grip control slide block, rather than by hook hook the contraception bail go out, therefore, can avoid injury that surrounding tissue is caused, reduce operation receiveing person's misery.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
