Abstract

The invention discloses a forceps body of tracheal foreign body forceps. The forceps body is integrally molded by elastic rubber or plastic and structurally comprises a tubular pipe joint b, a tubular supporting ring, a spherical clamping jaw connecting surface and three clamping jaws which are connected sequentially and integrally, wherein the three clamping jaws are evenly connected on the outer surface of the clamping jaw connecting surface and located on the same circumference; a piston body is glidingly connected with the inner wall of the tubular pipe joint b, and a connecting rod is connected between the center of the piston body and the center of the clamping jaw connecting surface; through holes are evenly formed in the clamping jaw connecting surface and circumferentially distributed with the connecting rod serving as a center in an arrayed manner. The forceps body is integrally molded by the elastic rubber or plastic and is convenient to machine and low in production cost. The piston body is driven by negative pressure to move towards a piston barrel so as to drive the clamping jaw connecting surface to dent inwards, and then the clamping jaw connecting surface drives the three clamping jaws to perform the clamping action to clamp a foreign body.

Description

A kind of trachea foreign body forceps caliper
Present patent application is the divisional application of following patent application
Title: a kind of trachea foreign body forceps and caliper
Application number: 201410379921.3

Technical field
The invention belongs to medical instruments field, be specifically related to foreign body in trachea wrench structure.
Background technology
Foreign body can hinder breathing by mistake after sucking respiratory tract, can cause suffocating even dead, must take out in time behind Foreign body aspiration time serious. Usual foreign body is to use tracheascope to coordinate trachea foreign body forceps to be operated, the foreign body forceps of prior art is all metal material, repeatedly use after cleaning and sterilizing, but the chela position of foreign body forceps is usual is that articulated form is connected with caliper main body, there is dead angle in link position, being difficult to thoroughly clean up, there is infection risk when reusing, result of use is undesirable. And if the foreign body forceps single use high cost of metal material and waste resource.
Summary of the invention
The technical problem to be solved is: the deficiency existed for prior art, it is provided that a kind of simple in construction, uses easy to operate, and gripping foreign body is reliable, and cost is low, can disposable trachea foreign body forceps caliper.
For realizing the purpose of the present invention, it is achieved by the following technical solutions:
A kind of trachea foreign body forceps caliper, described caliper is by having elastic rubber or integrally moulded, and described caliper is structurally integrally connected and composed successively by the pipe joint b of tubular, a pushing out ring of tubular, the jaw joint face of spheric and three jaws; The external diameter of described the pushing out ring external diameter more than pipe joint b, described jaw joint face is outwardly, and three jaws are uniformly connected on the outer surface of jaw joint face and three jaws are on a circumference, and the inner surface of described jaw forms clip tooth; Jointly it is embedded with the embedded pipe of a hard in described pipe joint b and a pushing out ring, in described jaw, is embedded with the reinforcing panel of hard; Forming an annular rib in the middle part of the inner surface of described jaw joint face, the circle diameter residing for annular rib and three jaws is equal, the 1/2-2/3 that diameter is a pushing out ring internal diameter of described annular rib; The jaw joint face of caliper is recessed to a pushing out ring under the suction function of pipe joint b side, thus driving three jaws to draw close in contraction state to jaw joint face center.
Described caliper is by gum elastic or integrally moulded, easy to process, and production cost is low, smooth surface impulse-free robustness or pointed end, and the sense of discomfort and the damages that produce trachea are small; Described jaw joint face is driven by negative pressure and produces Inward deflection thus driving three jaws to do pinching action to clamp foreign body; Described reinforce panel and embedded pipe makes that caliper has enough mechanical strengths and jaw joint face position can have good elasticity, it is ensured that jaw can effectively and firmly clamp foreign body. When described annular rib enables jaw joint face to be produced indent deformation by negative pressure, each jaw keeps consistent action, it is to avoid jaw action is unstable and makes foreign body again produce to move. The 1/2-2/3 that diameter is a pushing out ring internal diameter of described annular rib, such jaw joint face has good elasticity in the radial direction, coordinates with annular rib and has enough mechanical strengths, it is ensured that jaw action is strong.
