Abstract

The utility model discloses esophageal forceps for a thoracoscope. The esophageal forceps comprise a fixed handle, a movable handle hinged to the fixed handle and a hollow forceps lever. The forceps lever is rotatably connected with the fixed handle through a turning-wheel assembly, a push bar is arranged in the forceps lever, the tail end of the push bar is connected with the movable handle while the front end of the same is hinged to two connecting pieces, two pieces of forceps jaws are respectively hinged to the corresponding connecting pieces, the side projection of the forceps jaws is circular shaped, the front ends of the forceps jaws are respectively and fixedly connected with clamping mouths made of silica gel, and a clamping opening arches to two sides to form a circular arc which is symmetrical up and down. Since the clamping mouths made of the silicon gel are arranged at the ends of existing metal forceps jaws, the forceps jaws can be deformed and easily enter the thoracic cavity of a patient without squeezing the would of the patient when passing through a cannula on the would of the patient; silicon materials are soft and elastic, so that the forceps jaws cannot cause secondary injury to the esophageal and surrounding tissues and organs of the patient even if used for clamping and pulling for a long time.

Description

Thoracoscope esophageal forceps

Technical field

This utility model relates to medical instruments field, a kind of thoracoscope esophageal forceps of specific design.

Background technology

Along with the development of medical science, under thoracoscope esophagus Minimally Invasive Surgery little with its wound, recover fast, the advantages such as cardio-pulmonary function impact is little progressively replaced to part open chest surgery.At present domestic and international most of hospitals thoracic surgery has been carried out esophagus Minimally Invasive Surgery under thoracoscope, in esophagus Minimally Invasive Surgery, the appearing of esophagus, tractive and free be vital step, often determining the even success or failure of quality of operation.Elastic separating plier, nipper, suction pump or the suspender belts etc. of relying on are used in conjunction with complete operation more now, the jaw of existing elastic separating plier and nipper is all that metal material is made, and indentation, clamping and tractive easily cause secondary damage to patient's esophagus, extend patient's convalescent period.Prior art mainly relies on elastic separating plier or nipper to dial forward with the method for flipping and complete the separated of esophagus and surrounding tissue esophagus, by most experts, received and adopt at present, but its often charge less that appears to esophagus and surrounding tissue is divided, it is convenient not to use, and may cause certain pair damage.And complete the appearing of esophagus, tractive and free its major defect with suspender belt, be exactly that suspender belt is mobile convenient not, fixing reliable not on esophagus.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of thoracoscope esophageal forceps, and the pair in the time of effectively reducing tractive esophagus, patient being caused is damaged.

This utility model is achieved through the following technical solutions:

Thoracoscope esophageal forceps, comprise fixed handle, be hinged on the flexible handle on fixed handle, and the claw beam of hollow, claw beam is rotationally connected by wheel set assembly and fixed handle, is provided with push rod in claw beam, and the tail end of push rod is connected with flexible handle, front end is hinged with two braces, two jaws are hinged on respectively on brace, the front end of two jaws is fixed with respectively clamping mouth, and described clamping mouth adopts silica gel to make, and the clamp port of described clamping mouth arches upward to both sides and forms laterally zygomorphic circular arc.

This utility model further improvement project is that the root of clamping mouth is socketed in the end of described jaw, the clamp port indentation of described clamping mouth.

This utility model further improvement project is on described fixed handle, flexible handle, all to offer finger ring.

Compared to the prior art this utility model has the following advantages:

This utility model establishes in existing metal jaw end the clamping mouth that silica gel is made, when esophageal forceps comes and goes the sleeve pipe on patient's wound, this clamping mouth can be out of shape and is easy to enter patient thoracic cavity and can not cause extruding to patient's wound, when operation is carried out, the operations such as esophagus is clipped in two circular arcs between clamping mouth and realizes tractive, dissociates, even due to silica gel material matter soft clamping and tractive for a long time, can not cause secondary damage to patient's esophagus and surrounding tissue, organ yet.

The specific embodiment

Thoracoscope esophageal forceps as shown in Figure 1, 2, 3, comprises fixed handle 1, is hinged on the flexible handle 2 on fixed handle 1, and the claw beam 3 of hollow, and claw beam 3 is rotationally connected by wheel set assembly 4 and fixed handle 1.In claw beam 3, be provided with push rod 5, the tail end of push rod 5 is connected with flexible handle 2, front end is hinged with two braces, and two jaws 6 are hinged on respectively on brace, pushes away, post-tensioning is realized respectively jaw closing and closing before push rod 3.In the present embodiment, the side-looking projection of jaw 6 is circular arc, and arc-shaped structure makes itself and the body of rod present an angle, is convenient to vise esophagus and is revealed; Front end at two jaws 6 is fixed with respectively clamping mouth 7, and clamping mouth 7 adopts silica gel to make, and its clamp port arches upward to both sides and forms laterally zygomorphic circular arc, and in operation, esophagus is clipped in circular arc.

In the present embodiment, the clamp port indentation that the root of clamping mouth 7 is socketed in the end of jaw 6, clamping mouth 7 increases chucking power; On fixed handle 1, flexible handle 2, all offer finger ring 8, person's finger easy to use is through holding handle, easy to use.
