Foreign body net clamp for surgical operation

Abstract

The invention discloses a foreign body net clamp for surgical operation. The clamp comprises a pneumatic control handle, a clamp body, and a connection pipe connecting the clamp body with the pneumatic control handle, wherein the clamp body is formed by an ellipsoid capsule and a circular tubular pipe joint b which is integrally connected to one end of the long axial direction of the capsule; the capsule is of a hollow structure; a round clamp opening is shaped in the wall surface of the other end of the long axial direction of the capsule; the diameter of the clamp opening is smaller than the length of the short shaft of the capsule; a telescopic pipe is shaped in the inner circumference of the clamp opening; multiple supporting pipes are uniformly shaped in the inner wall of the capsule along the long axial direction; one end, far away from the pipe joint b, of each supporting pipe is connected with the telescopic pipe, the ends, close to the pipe joint b, of the supporting pipes are connected and are communicated with the pipe joint b. The clamp body is compact and ingenious in structure; once processing shaping can be realized through 3D printing; the external wall of the clamp body is smooth and in an elliptical sphere shape; the stimulation and damage to in vivo tissue pipelines is little; the size of the clamp body can be processed into various sizes so as to adapt to different parts.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a structure of foreign body forceps for trachea. Background technique [0002] Foreign objects that are accidentally inhaled into the respiratory tract will hinder breathing, and in severe cases, it will cause suffocation or even death. After inhaling foreign objects, they must be removed in time. Usually, foreign body removal is performed by using a bronchoscope with tracheal foreign body forceps. The foreign body forceps in the prior art are made of metal, and are reused many times after cleaning and disinfection. However, the jaws of the foreign body forceps are usually connected to the main body of the forceps in a hinged form. , There is a dead angle in the connection position, it is difficult to clean thoroughly, there is a risk of infection when it is reused, and the use effect is not ideal. However, if the foreign body forceps made of metal are used once, ...

Problems solved by technology

Usually, foreign body removal is performed by using a bronchoscope with tracheal foreign body forceps. The foreign body forceps in the prior art are made of metal, and are reused many times after cleaning and disinfection. However, the jaws of the foreign body forceps are usually connected to the main body of the forceps in a hinged form. , there is a dead angle in the connection position, it is difficult to clean thoroughly, there is a risk of infection when reused, and the use effect is not ideal

However, if the foreign body forceps made of metal are used once, the cost is too high and resources are wasted.

The name of the applicant's application on September 21, 2014 is: a trachea foreign body forceps and forceps body, the patent application number is: 2014104843355 solves the above problems, but the forceps body of this foreign body forceps clamps foreign bodies The claws are opened in front of the pliers body. When grasping some irregularly shaped and large foreign objects or even with sharp thorns, they cannot completely wrap the foreign objects. It is easy to injure them during the process of dragging the foreign objects after clamping them. Patient tissue, unsatisfactory use
