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.

Abstract

The invention discloses a body structure of tracheal foreign body forceps. The forcep body is integrally formed by elastic rubber or plastic and obtained through sequential and integral connection of a round-tube-shaped pipe joint b, a round-tube-shaped supporting ring, a spherical clamping jaw connecting surface and three clamping jaws, wherein the three clamping jaws are evenly connected to the outer surface of the clamping jaw connecting surface and located on the same circle, a piston body is connected to the inner wall of the pipe joint b in a sliding mode, and a connecting rod is connected between the piston body and the center of the clamping jaw connecting surface; through holes are evenly formed in the clamping jaw connecting surface and distributed into a circular array with the connecting rod as the center. The forcep body is convenient to machine and low in production cost. The piston body is driven under negative pressure to move towards a piston cylinder so as to drive the clamping jaw connecting surface to be concave inwards, and then the clamping jaw connecting surface drives the three clamping jaws to conduct clamping so as to clamp foreign matter.

Description

[0001] This patent application is a divisional application of the following patent application [0002] Name: Tracheal foreign body forceps and forceps body [0003] Application number: 201410379921.3 [0004] Application date: 2014-08-04. technical field [0005] The invention belongs to the field of medical equipment, and in particular relates to a structure of a tracheal foreign body forceps. Background technique [0006] 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 for...
