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, and in particular to foreign body in airpassage wrench structure.
Background technology
Foreign matter can be hindered breathing after suction respiratory tract by mistake, can cause asphyxia even dead when serious, after aspirated foreign body
It must take out in time.Usual foreign body is to coordinate trachea foreign body forceps to be operated using airway wall, the foreign body forcepses of prior art
All it is metal material, is repeatedly used after cleaning and sterilizing, but the chela position of foreign body forcepses is generally hinge with caliper main body
Form connection is connect, link position has dead angle, it is difficult to which thoroughly cleaning is clean, there is infection risk, using effect during reuse
It is undesirable.And if the disposable cost of the foreign body forcepses of metal material is too high and waste of resource.
The content of the invention
The technical problems to be solved by the invention are:In view of the shortcomings of the prior art there is provided one kind is simple in construction, make
With easy to operate, gripping foreign matter is reliable, low cost, trachea foreign body forceps caliper that can be disposable.
To realize the purpose of the present invention, it is achieved using following technical scheme:
A kind of trachea foreign body forceps caliper structure, described caliper is described by flexible rubber or integrally moulded
Caliper in structure by the pipe joint b of tubular, the support ring of tubular, the clamping jaw joint face of spheric and three clamping jaws according to
Secondary integrally connected is constituted;The external diameter of the support ring is more than outside pipe joint b external diameter, described connection tube outer surface and support ring
Flush;Described clamping jaw joint face is outwardly, and three clamping jaws are uniformly connected on the outer surface of clamping jaw joint face and three
Individual clamping jaw is on a circumference, and the inner surface of the clamping jaw forms clip tooth;It is common in described pipe joint b and support ring
It is embedded with the reinforcing panel that hard is embedded with the embedded pipe of a hard, described clamping jaw;Described pipe joint b inwalls are slided
A piston body is connected with, a connecting rod, a diameter of support of connecting rod are connected between piston body and the center of clamping jaw joint face
The 1/10-1/5 of ring internal diameter;It is uniform on described clamping jaw joint face to offer through hole, through hole circumferentially array centered on connecting rod
Distribution;The piston body of caliper is moved under suction function to pipe joint b ends, and drives clamping jaw connection towards support by connecting rod
Ring is recessed, so as to drive three clamping jaws to be drawn close to clamping jaw joint face center in contraction state.
Described caliper is easy to process by elastic caoutchouc or integrally moulded, and production cost is low, surface Glabrous thorn
Or pointed end, the sense of discomfort produced to tracheae and damage are small;The piston body is driven to piston cylinder direction by negative pressure and moved
So as to drive clamping jaw joint face indent, clamping jaw joint face then drives three clamping jaws to do pinching action to clamp foreign matter;Described
On the one hand through hole enables piston body both sides produce pressure differential and moved beneficial to piston body, and another aspect foreign matter stuck position may be deposited
A small amount of hydrops can be sucked from through hole in the space between clamping jaw joint face and piston body;Described reinforcing panel and embedded pipe
Make that caliper has enough mechanical strengths and clamping jaw joint face position can have good elasticity, it is ensured that clamping jaw can effectively and
Firmly clamp foreign matter.The 1/10-1/5 of a diameter of support ring internal diameter of the connecting rod, such connecting rod both can guarantee that to be connected with clamping jaw
Junction is connected firmly, while can ensure that the deformation quantity of clamping jaw joint face is larger again, clamping jaw is preferably clamped foreign matter.
