Abstract

The utility model relates to biopsy forceps. The biopsy forceps comprise hand shanks, claw beams and jaws, wherein the claw beams are provided with a plurality of black and white scale marks at intervals at the positions which are 50cm away from the hand shanks and the positions which are 10cm away from the jaws. The scale marks are arranged at two ends of the claw beams, so that a medical worker can visually observe the sizes of the external claw beams entering inside the body and the depth of an endoscope entering inside diseased tissue; and a group of black and white scale marks are 5mm, so as to be convenient to calculate. A spring tube achieves a slide chute through the ports of the hand shanks, and is plastically welded and fixed together with the ports of the hand shanks; the biopsy forceps ensure that the spring tube does not sway in a working process; an inhaul cable is movably connected with a slide handle; and the inhaul cable can freely control the jaws. Therefore, the biopsy forceps are safe and practical.

Description

A kind of biopsy forceps

Technical field

This utility model relates to a kind of biopsy forceps, especially a kind of biopsy forceps with scale.

Background technology

Splanchnoscopy is as a kind of method of auxiliary diagnosis, and that uses in clinical medicine checks is more and more extensive, and biopsy forceps can extend in the patient body by endoscope channel, diseased region is checked the gripping pathological tissues.At present biopsy forceps commonly used in use, because measurement endoscope that can't be definite enters size in body, can only lean on estimation, and this brings very large inconvenience for work of medical worker, more is unfavorable for patient's treatment.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, and a kind of biopsy forceps is provided.

The technical scheme that realizes this utility model purpose is: a kind of biopsy forceps, comprise handle, claw beam, jaw, and close on the position and the position of closing on jaw 10cm of handle 50cm on described claw beam, be provided with some chequered with black and white graduation marks.

Further, described handle is made of core bar, handle port and the sliding handle with chute, described sliding handle is enclosed within the core bar outside, described claw beam is made of bourdon tube and the inner drag-line of outside, described bourdon tube passes the handle port and arrives chute, and with handle port weldering mould fixing, described drag-line and sliding handle flexible connection.

Further, the scale live width 3mm of described black, the scale live width 2mm of described white.

Further, on described claw beam, the quantity of two place's graduation marks is all 22, and the quantity of black, the white graduation mark in everywhere is respectively 11.

The utlity model has positive effect: the two ends at the biopsy forceps claw beam all are provided with graduation mark, medical worker can be observed very intuitively outside claw beam and enter the degree of depth that size in body and endoscope enter pathological tissues, one group of black, white graduation mark is 5mm, is convenient to observe and calculates.Bourdon tube passes the handle port and arrives chute, and moulds fixingly with the weldering of handle port, has guaranteed that bourdon tube can not rock when work, drag-line and sliding handle flexible connection, and drag-line can freely be controlled jaw, and is very safe and practical.

Description of drawings

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail this utility model according to specific embodiment also by reference to the accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Wherein: 1, core bar, 2, chute, 3, sliding handle, 4, drag-line, 5, bourdon tube, 6, the handle port, 7, jaw.

The specific embodiment

As shown in Figure 1, this utility model is a kind of biopsy forceps, comprise handle, claw beam, jaw 7, close on the position and the position of closing on jaw 710cm of handle 50cm on claw beam, be provided with some chequered with black and white graduation marks, the scale live width 3mm of black, the scale live width 2mm of white, the quantity of two place's graduation marks is all 22, and the quantity of black, the white graduation mark in everywhere is respectively 11.Two ends at the biopsy forceps claw beam all are provided with graduation mark, and medical worker can be observed very intuitively outside claw beam and enter the degree of depth that size in body and endoscope enter pathological tissues, and one group of black, white graduation mark is 5mm, is convenient to observe and calculates, and is very safe.

Handle is made of core bar 1, handle port 6 and the sliding handle 3 with chute 2, sliding handle 3 is enclosed within core bar 1 outside, claw beam is made of bourdon tube 5 and the inner drag-line 4 of outside, bourdon tube 5 passes handle port 6 and arrives chutes 2, and with 6 welderings of handle port mould fixing, when work, weldering is moulded fixing bourdon tube 5 and can not rocked, drag-line 4 is flexibly connected with sliding handle 3, and drag-line 4 can freely be controlled jaw 7, and is very practical.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
