Description

Foreign body in trachea clamp device
Present patent application is the divisional application of following patent application
Title: foreign body in trachea clamp device and caliper
Application number: 201410380315.3
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 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 foreign body in trachea clamp device.
For realizing the purpose of the present invention, it is achieved by the following technical solutions:
A kind of foreign body in trachea clamp device, includes caliper, the connecting tube of pneumatic control handle and the connection gentle dynamic joystick of 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, the pushing out ring of tubular, the rib joint face of spheric and four holding pieces; The external diameter of described the pushing out ring external diameter more than pipe joint b, the periphery of pipe joint b forms anticreep convex tendon; Described connecting tube is connected with the outer wall interference fit of pipe joint b; Described rib connection is recessed towards supporting ring, the periphery of four holding piece uniformly adjacent outer surfaces being connected to rib joint face, the outer surface of holding piece is excessively connected with the outer surface smoother of a pushing out ring, the end of holding piece is tapered, the end of four holding pieces surrounds a circular open front, and the diameter of open front is the 1/10-1/5 of a pushing out ring external diameter; Latasuture is left between adjacent two holding pieces; The inner side of each described holding piece forms support rod, and the bottom of support rod is connected on the outer surface of described rib joint face, and the bottom of support rod extends to the center of rib joint face; Jointly it is embedded with the embedded pipe of a hard in described pipe joint b and a pushing out ring, in described support rod, is embedded with the reinforcing panel of hard; Described pipe joint b inwall slidably connects a piston body, is connected to a connecting rod between the center of piston body and rib joint face, and the diameter of connecting rod is the 1/10-1/5 of a pushing out ring internal diameter; Described rib joint face uniformly offers through hole, through hole circumferentially array distribution centered by connecting rod; Described pneumatic control handle includes a piston cylinder and the piston coordinated with piston cylinder, and piston is connected to the piston rod that end extend out to outside piston cylinder, and piston cylinder front end is connected with a pipe joint a being connected with described connecting 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 by a jointed shaft b in the middle part of flexible handle; The end of described piston rod forms the hinge eyes of a bar hole shape, flexible handle is fixedly connected with a jointed shaft a, jointed shaft a and is limited in described hinge eyes; Described flexible handle drives piston to produce air pressure to piston cylinder anterior movements, the piston body of caliper moves to a pushing out ring direction under air pressure promotes, driving rib joint face to bulge thereby through connecting rod, rib joint face drives support rod to be flared out thus driving holding piece together to open; After unclamping flexible handle, rib joint face resets under himself elastic force effect, and support rod and holding piece are also reset to contraction state.
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 piston body is driven by air pressure and moves to holding piece direction, thus rib joint face is outwards ejected, then rib joint face drives three support rod end outward expansion then to drive holding piece to launch, air pressure cancels piston body in process, rib joint face resets, thus holding piece does pinching action to wrap foreign body; Described air pressure makes piston move acquisition along piston cylinder front by flexible handle of holding with a firm grip, easy to operate; Described reinforce panel and embedded pipe makes that caliper has enough mechanical strengths and rib joint face position can have good elasticity, it is ensured that holding piece can effectively and firmly clamp foreign body. Described through hole makes piston body both sides can produce pressure differential and be beneficial to piston body and move on the one hand, and foreign body stuck position a small amount of hydrops that may be present can suck in the space between rib joint face and piston body from through hole on the other hand. Described caliper is normally closed type, and pneumatic control handle has only to the action when jaw foreign body, is wrapped in after among holding piece until foreign body and can unclamp pneumatic control handle, easy to operate. The diameter of described open front is the 1/10-1/5 of a pushing out ring external diameter, so both can ensure that holding piece easily opened, and can guarantee that again nipped foreign body will not come off from open front. The diameter of described connecting rod is the 1/10-1/5 of a pushing out ring internal diameter, and such connecting rod both can guarantee that and has been connected firmly with rib joint face, can ensure that again that the deformation quantity of rib joint face is relatively big simultaneously, enables holding piece to open by a relatively large margin, be beneficial to and clamp the foreign body that volume is bigger. The 1/2-2/3 that diameter is a pushing out ring internal diameter of described annular rib, such rib joint face has good elasticity in the radial direction, coordinates with annular rib and has enough mechanical strengths, it is ensured that holding piece action is strong.
