Title: a kind of trachea foreign body forceps and caliper
Application number: 201410379921.3
The applying date: 2014-08-04.
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 uses tracheascope to coordinate trachea foreign body forceps to operate, 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, be 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
Technical problem to be solved by this invention is: the deficiency existed for prior art, and provide a kind of structure simple, use easy to operate, gripping foreign body is reliable, and cost is low, can disposable trachea foreign body forceps caliper.
For realizing the object of the present invention, be achieved by the following technical solutions:
A kind of trachea foreign body forceps caliper structure, described caliper is by having elastic rubber or integrally moulded, and described caliper is is structurally integrally connected and composed successively by the pipe joint b of tubular, the support ring of tubular, the jaw joint face of spheric and three jaws; The external diameter of described support ring is greater than the external diameter of pipe joint b, described connection tube outer surface and support ring flush with outer surface; Described jaw joint face is outwardly, and on the outer surface that three jaws are evenly connected to jaw joint face and three jaws are in one circumferentially, the inner surface of described jaw forms clip tooth; Jointly be embedded with the embedded pipe of a hard in described pipe joint b and support ring, in described jaw, be embedded with the reinforcing panel of hard; Described pipe joint b inwall slidably connects a piston body, is connected with a connecting rod between the center of piston body and jaw joint face, and the diameter of connecting rod is the 1/10-1/5 of support ring internal diameter; Described jaw joint face evenly offers through hole, through hole circumferentially array distribution centered by connecting rod; The piston body of caliper moves to pipe joint b end under suction function, and drives jaw joint face to be recessed to support ring by connecting rod, thus drives 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 produced trachea is small with damage; Described piston body drives to the motion of piston cylinder direction by negative pressure thus drives jaw joint face indent, and jaw joint face drives three jaws to do pinching action to clamp foreign body then; Described through hole makes piston body both sides produce pressure differential on the one hand and is beneficial to piston body and moves, and a small amount of hydrops that foreign body stuck position may exist on the other hand can suck in the space between jaw joint face and piston body from through hole; Described reinforcing panel and embedded pipe make that caliper has enough mechanical strengths and jaw joint face position can have good elasticity, ensure that jaw can effectively and firmly clamp foreign body.The diameter of described connecting rod is the 1/10-1/5 of support ring internal diameter, and such connecting rod can ensure to be connected firmly with jaw joint face, can guarantee again that the deformation quantity of jaw joint face is comparatively large simultaneously, enable jaw clamp foreign body better.
