Foreign body net tongs structure for use in surgical operation

Abstract

The invention discloses a foreign body net tongs structure for use in surgical operation. The foreign body net tongs structure comprises a pneumatic control handle, a tongs body and a connection tube, wherein the connection tube is used for connecting the tongs body with the pneumatic control handle; the tongs body consists of an oval bag body and a circular tube joint b which is integrally connected to one end of the bag body in a long-axle direction; the bag body has a hollow structure; a circular nip is formed in the wall surface of the other end of the bag body in the long-axle direction; the diameter of the nip is smaller than the length of a short axle of the bag body; a telescopic tube is molded on the inner circumference of the nip; a plurality of support tubes are uniformly molded on the inner wall of the bag body in the long-axle direction; one end, which is far away from the tube joint b, of each support tube is communicated with the telescopic tubes; one end, which is close to the tube joint b, of each support tube is connected together, and is communicated with the tube joint b. The tongs body structure is compact and skillful, one-step machining and molding can be realized through 3D (three-dimensional) printing, the outer wall of the tongs body is smooth and oval, the stimulation and injury to in-vivo tissue vessels are small, and different sizes of tongs bodies can be machined in order to adapt to different positions.

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.

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
