Abstract

The utility model relates to a forceps holder opening device of medical operating forceps. The forceps holder opening device comprises a first forceps holder, a second forceps holder, a forceps holder base, a pull rod and a forceps body, wherein the forceps holder base is fixedly connected with the forceps body, and the pull rod is sleeved with the forceps body. The forceps holder opening device is characterized in that the second forceps holder is installed on the forceps holder base through a fixed pin, and the first forceps holder and the second forceps holder are connected through a forceps holder connecting pin. The first forceps holder is connected with the pull rod through a pull rod connecting pin. The forceps holder opening device of the medical operating forceps is reasonable in structure, has air inflation and attraction functions and is good in the safety effect of an operation.

Description

The clamp device for spreading of medical surgical forceps

Technical field

This utility model relates to a kind of clamp device for spreading of medical surgical forceps.

Background technology

Medical surgical forceps is of a great variety, is applied to all kinds of medical operatings, and its clamp device for spreading is to design according to the kind of medical surgical forceps.Medical surgical forceps clamp device for spreading mainly contains that the clamp single action struts and clamp is two moving struts in the prior art: it is 2 connections of active clamp low side that the clamp single action struts, and pull bar sliding active clamp forms the monolateral folder that struts of active clamp and closes; Clamp is two moving struts that to be two clamp low sides win in succession and is connected with two, 4 connections of low side, after the pull bar push-and-pull, form diamond shaped flexible make clamp two move to strut to press from both sides close.It is the monolateral swing of clamp that the clamp single action struts, and causes the limitation of apparatus operation application.The two moving diamond shaped of clamp are flexible to be strutted and folder closes and is mounted in the clamp seat, and the telescopic oscillating friction is large, if be applied to coagulation series pincers class, affect the service life of insulating part, even can conduction in the clamp seat, cause the insulating part damage, and caliper is scrapped; In addition, pull bar pulls the clamp folder to close the operation application effect that strength can not meet large-scale nipper.

The utility model content

Technical problem to be solved in the utility model is to overcome above shortcomings in prior art, and provides a kind of simple for structure, and long service life is cost-saving, the clamp device for spreading of effective medical surgical forceps.

This utility model solves the problems of the technologies described above adopted technical scheme:

A kind of clamp device for spreading of medical surgical forceps, comprise the first clamp, the second clamp, clamp seat, pull bar, caliper, clamp seat and caliper are connected and fixed, drag link sleeve is in caliper, it is characterized in that the second clamp is arranged on the clamp seat by steady pin, the first clamp, the second clamp connect by the clamp connecting pin, and the first clamp is connected with pull bar by link pin.

This utility model compared with prior art, has the following advantages and effect: reasonable in design, and long service life, cost-saving, operation safety is effective.

The accompanying drawing explanation

The structural representation that Fig. 1 is this utility model embodiment.

Fig. 2 is this utility model embodiment clamp softened state schematic diagram.

The specific embodiment

Referring to Fig. 1, Fig. 2, this utility model embodiment is provided with the first clamp 1, the second clamp 2, steady pin 3, clamp connecting pin 4, link pin 5, clamp seat 6, pull bar 7, caliper 8, clamp seat 6 is connected and fixed with caliper 8, pull bar 7 is enclosed within caliper 8, the second clamp 2 use steady pins 3 are arranged on clamp seat 6, the first clamp 1, the second clamp 2 connect and can rotate by clamp connecting pin 4, the first clamp 1 is connected by link pin 5 with pull bar 7, forms steady pin 3,

clamp connecting pin

4,5 three connections of link pin; Solved in prior art that flexible 4 connections of diamond shaped strut and folder closes and all is positioned at the clamp seat, the telescopic oscillating large defect that rubs.

The present embodiment pull bar 7 directly promotes and pulls the first clamp 1, makes that 2 pairs of the first clamp 1 and the second clamps are moving struts (Fig. 2) and folder closes (Fig. 1), has saved two flexible connecting plates of diamond shaped in the prior art, makes the 6 internal clearances increasings of clamp seat, and friction reduces; If be applied to coagulation series pincers class, insulating part can increase thickening, has reduced the conduction in clamp seat 6, extends the service life of insulating part and caliper.

The present embodiment the second clamp 2 use steady pins 3 are fastened on clamp seat 6 and can rotate, and pull bar 7 directly promotes and pull the first clamp 1, form two moving strut and folder closes; Absorb 2 connection clamp single actions of low side and strutted the advantage that pulling force is large, there is again two moving and strut and press from both sides the effect of closing, avoided flexible two the moving of prior art diamond shaped to strut and press from both sides the defects of closing; Material and production cost have been saved.

Allly according to this utility model patent, conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of this utility model patent.

Claims

1. the clamp device for spreading of a medical surgical forceps, comprise the first clamp, the second clamp, clamp seat, pull bar, caliper, clamp seat and caliper are connected and fixed, drag link sleeve is in caliper, it is characterized in that the second clamp is arranged on the clamp seat by steady pin, the first clamp, the second clamp connect by the clamp connecting pin, and the first clamp is connected with pull bar by link pin.
