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 trachea foreign body tweezers and a tweezer body. The tweezer body is integrally molded by use of elastic rubber or plastics; the tweezer body is structurally composed of a circularly tubular pipe joint b, a circularly tubular support ring, a spherical surface-shaped claw connecting surface and three claws, all of which are orderly and integrally connected together; the three claws are evenly connected to the external surface of the claw connecting surface and located in the same circle; a piston body is slidingly connected to the inner wall of the pipe joint b, and a connecting rod is connected between the piston body and the center of the claw connecting surface; through holes are evenly formed in the claw connecting surface and distributed in a circumferential array with the connecting rod as the center. The tweezer body is integrally molded by use of the elastic rubber or plastics, and thus is convenient to manufacture and low in manufacturing cost. The piston body is driven by negative pressure to move toward a piston barrel so that the claw connecting surface can be recessed, and then the three claws are driven by the claw connecting surface to realize a clamping action so as to clamp a foreign body.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a structure of a tracheal foreign body forceps. 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, ...
