Description

A kind of trachea foreign body forceps

Technical field

This utility model belongs to medical instruments field, is 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 in the utility model 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.

For realizing the object of this utility model, be achieved by the following technical solutions: a kind of trachea foreign body forceps, includes caliper, the connection tube of pneumatic control handle and the gentle dynamic joystick of connection caliper; 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, and described connection tube is connected with the outer wall interference fit 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; Described jaw joint face evenly offers through hole, through hole circumferentially array distribution centered by connecting rod; The piston that described pneumatic control handle includes a piston cylinder and coordinates with piston cylinder, piston is connected with end and extend out to piston rod outside piston cylinder, piston cylinder front end is connected with a pipe joint a be connected with described connection tube; Piston cylinder lateral wall is fixedly connected with a fixed handle, and piston rod end is hinged with a flexible handle, is hinged on fixed handle in the middle part of flexible handle by a jointed shaft b; The end of described piston rod forms the hinge eyes of a bar hole shape, and flexible handle is fixedly connected with a jointed shaft a, jointed shaft a is limited in described hinge eyes.

Compared with prior art, the beneficial effects of the utility model are: 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 negative pressure makes piston move acquisition after piston cylinder by flexible handle of holding with a firm grip, easy to operate; 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.When described annular rib enables jaw joint face produce indent deformation by negative pressure, each jaw is consistent action, avoids jaw action unstable and makes foreign body again produce movement.

Detailed description of the invention

With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.

According to shown in Fig. 1 to Fig. 6, a kind of trachea foreign body forceps described in the present embodiment, includes caliper 3, the connection tube 2 of pneumatic control handle 1 and the gentle dynamic joystick of connection caliper; 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 b30 of tubular, the support ring 31 of tubular, the jaw joint face 32 of spheric and three jaws 33; The external diameter of described support ring is greater than the external diameter of pipe joint b, and described connection tube 2 is connected with the outer wall interference fit of pipe joint b; 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 331; Jointly be embedded with the embedded pipe 34 of a hard in described pipe joint b and support ring, in described jaw, be embedded with the reinforcing panel 332 of hard; Described pipe joint b inwall slidably connects a piston body 36, is connected with a connecting rod 35 between the center of piston body and jaw joint face; Described jaw joint face evenly offers through hole 322, through hole circumferentially array distribution centered by connecting rod; The piston that described pneumatic control handle includes a piston cylinder 11 and coordinates with piston cylinder, piston is connected with end and extend out to piston rod 12 outside piston cylinder, piston cylinder front end is connected with a pipe joint a111 be connected with described connection tube; Piston cylinder lateral wall is fixedly connected with a fixed handle 14, and piston rod end is hinged with a flexible handle 13, is hinged on fixed handle in the middle part of flexible handle by a jointed shaft b132; The end of described piston rod forms the hinge eyes 121 of a bar hole shape, and flexible handle is fixedly connected with a jointed shaft a131, jointed shaft a is limited in described hinge eyes.

During use, tracheascope is stretched into position near intratracheal foreign body together with caliper and connection tube, is observed by tracheascope, make jaw aim at foreign body; Rotate towards fixed handle direction by pressing described flexible handle bottom, jointed shaft a coordination hinge endless belt on flexible handle moves piston rod and moves to piston cylinder rear, thus make to produce negative pressure in piston cylinder, also in negative pressure state in the caliper be connected with piston cylinder by connection tube, described piston body moves to piston cylinder direction under suction function, thus drive jaw joint face indent, jaw joint face drives three jaws make pinching action thus clamped by foreign body then, flexible handle keeps state of holding with a firm grip, and caliper is drawn out to trachea outward together with connection tube.
