Abstract

The utility model relates to a biopsy forceps with an adjusting device, belonging to the technical field of medical appliances. The biopsy forceps comprises a forceps body for inserting into the flexible conduit of a gastroscope, the front end forceps head of the forceps body passes through the flexible conduit and is positioned at one end of the gastroscope 1, and a forceps handle at the other end of the forceps body, which is positioned on the flexible conduit of the gastroscope, controls the movement of the biopsy forceps. The biopsy forceps is characterized in that an operating line parallel to the forceps body is additionally arranged, one end of the operating line is fixedly connected with the forceps head of the biopsy forceps, and the other end thereof protrudes the flexible conduit of the gastroscope and exposes outside together with the forceps handle. The biopsy forceps with the adjusting device solve the accurate positioning difficulty of the prior biopsy forceps during biopsy; and has the advantages of reasonable structure, flexible use, and good accuracy and rapidness. The degree of curvature of the front end of the biopsy forceps can be optionally adjusted to reach the accurate position required for sampling.

Description

A kind of biopsy forceps with adjusting device

One, technical field

This utility model relates to a kind of biopsy forceps with adjusting device, belongs to technical field of medical appliance structures.

Two, background technology

At present, when gastroscopy, usually need to get pathology, though present gastroscope front end bending is very flexible, but at the bottom of some positions such as duodenum, stomach arranged, lesser gastric curvature, esophagus and cardia etc., get in the pathological process and still can run into some problems, because biopsy forceps always goes ahead along the biopsy hole, and lesion locations comparatively departs from, to get the comparatively satisfied difficulty of organizing during biopsy.

Three, summary of the invention

The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and provides a kind of rational in infrastructure, uses flexibly, accurate quick, the biopsy forceps that can arbitrarily adjust the band adjusting device of front end flexibility.

A kind of biopsy forceps of the present utility model with adjusting device, the caliper 2 that comprises the soft pincers road 3 that is used to insert gastroscope 1, the front end binding clip 5 of caliper 2 passes the end that soft pincers road 3 is positioned at gastroscope 1, be positioned at the activity of the caliper 2 other ends pincers handle 4 control biopsy forcepss 2 of gastroscope 1 soft pipeline 3, special character is to add a control wire 6 arranged side by side with caliper 2, one end of control wire 6 is fixedlyed connected with the binding clip 5 of biopsy forceps 2, and the soft pincers road 3 that the other end then stretches out gastroscope 1 together is exposed on the external with pincers handle 4;

Described control wire 6 is tied a knot with the end that pincers handle 4 together is exposed on the external, so that form fixed operating side 7;

Described control wire 6 adopts is the material that rigidity and toughness all reach requirement, tissue is not had harm, is difficult for getting rusty.

A kind of biopsy forceps with adjusting device of this utility model can not accurate localized difficulty when having solved existing biopsy forceps biopsy, and is rational in infrastructure, use flexibly, accurately quick, can arbitrarily adjust the front end flexibility, to reach the required exact position of sampling.

Four, description of drawings

The A place enlarged diagram of Fig. 2: Fig. 1;

Operating side in the drawings, 1, gastroscope, 2, biopsy forceps, 3, soft pincers road, 4, the pincers handle, 5, binding clip, 6, control wire, 7.

Five, the specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.

Embodiment 1

A kind of biopsy forceps with adjusting device of present embodiment is with reference to Fig. 1-2, be to add a control wire on the next door of original biopsy forceps, one end is fixed on the front end of biopsy forceps, in the biopsy hole, pass the gastroscope shank with biopsy forceps when getting pathology, leave the gastroscope front end, the other end is exposed at the outside in biopsy hole near the biopsy handle, knotting is so that form fixed operating side; The caliper 2 that comprises the soft pincers road 3 that is used to insert gastroscope 1, the front end binding clip 5 of caliper 2 passes the end that soft pincers road 3 is positioned at gastroscope 1, be positioned at the activity of the caliper 2 other ends pincers handle 4 control biopsy forcepss 2 of gastroscope 1 soft pipeline 3, special character is to add a control wire 6 arranged side by side with caliper 2, one end of control wire 6 is fixedlyed connected with the binding clip 5 of biopsy forceps 2, the soft pincers road 3 that the other end then stretches out gastroscope 1 together is exposed on the external with pincers handle 4, control wire 6 is tied a knot with the end that pincers handle 4 together is exposed on the external, so that form fixed operating side 7; Control wire 6 adopts is the material that rigidity and toughness all reach requirement, tissue is not had harm, is difficult for getting rusty.

Use this novel biopsy forceps of operating when getting pathological tissue, at first it is operated routinely from biopsy hole insertion soft pipeline and pass shank always away from the gastroscope front end, position in conjunction with the binding clip 5 of gastroscope direction by biopsy forceps 2, and then by control wire 6 cooperation adjustment positions, tension control wire 6 makes the biopsy forceps bending, at this moment binding clip 5 can be adjusted flexibility as required under the pulling force effect of control wire 6, can adjust the gastroscope bending direction by the gastroscope control section simultaneously, finally reach accurate ideal sample position.
