Abstract
The utility model discloses a kind of tong head of pneumatic type foreign body forceps, include integrated union joint, bulb and multiple chela; Described bulb is hollow structure, and bulb is connected with union joint, and union joint and described connection tube are connected; Described bulb forms the concave surface of an indent spherical shape, form the angle of 120 °-150 ° between the radial direction of concave surface central point and the length direction of union joint, described multiple chela is connected to the periphery of concave surface with circumference array; Described binding clip at least concave surface is elastomeric material, drives each chela to open when described concave surface is outwards heaved under gas pressure.During this foreign body forceps gripping foreign body, the probability of foreign body generation slippage is low, is beneficial to and takes out foreign body fast, reduces patient painful.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of foreign body forceps structure.
Background technology
The foreign body forceps of prior art is all metal material, repeatedly uses after cleaning and sterilizing, but the chela position of foreign body forceps is usually 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.The name that applicant applied on August 4th, 2014 is called: a kind of trachea foreign body forceps and caliper, application number is: the patent application of 2014103799213 solves the problems referred to above, so caliper chela when gripping foreign body of this kind of foreign body forceps opens in the front of caliper, in the process of some ganoid foreign body of gripping, foreign body can be pushed away forward by chela, not only can't clip foreign body, foreign body also can be made to slip into darker position; Or when foreign body is less, foreign body is in the outside of chela, presss from both sides less than foreign body inside chela, therefore this kind of foreign body forceps can not meet the needs capturing various foreign body.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of novel structure, can aim at and capture the tong head of the pneumatic type foreign body forceps of foreign body in more convenient Quick labor-saving ground.
For realizing the object of this utility model, being achieved by the following technical solutions: a kind of tong head of pneumatic type foreign body forceps, including integrated union joint, bulb and multiple chela; Described bulb is hollow structure, and bulb is connected with union joint, and union joint and described connection tube are connected; Described bulb forms the concave surface of an indent spherical shape, form the angle of 120 °-150 ° between the radial direction of concave surface central point and the length direction of union joint, described multiple chela is connected to the periphery of concave surface with circumference array; Described binding clip at least concave surface is elastomeric material, drives each chela to open when described concave surface is outwards heaved under gas pressure.
Further: curved in the longitudinal direction of the outer surface of described chela, described chela outer surface is between the scope of bulb place sphere.Such binding clip integral surface is smooth, is beneficial to binding clip and connection tube and stretches in trachea or esophagus and can not cause scratch to in-vivo tissue.
Further: described union joint outer surface circumferentially forms multiple anticreep convex tendon.Anticreep convex tendon makes union joint and connection tube be connected firmly.
Compared with prior art, the beneficial effects of the utility model are: the angle forming 120 °-150 ° between the radial direction of concave surface central point and the length direction of union joint, such chela at the after-opening opened towards side, binding clip front, behind confirmation foreign body position, binding clip is driven to rotate by rotating the pneumatic control handle strip pipe that is dynamically connected, make concave surface position alignment foreign body (between concave surface and foreign body reserved distance of being a bit larger tham chela length), the piston rod pressing pneumatic control handle produces air pressure and drives concave surface to bulge, chela is driven to open and further near foreign body, after the chela of extremely close binding clip forward portion extends and exceedes foreign body present position, the piston rod unclamping pneumatic control handle cancels air pressure, concave surface resets together with chela, so foreign body is scratched in the space that concave surface and each chela surround toward connection tube direction by chela.During this foreign body forceps gripping foreign body, the probability of foreign body generation slippage is low, is beneficial to and takes out foreign body fast, reduces patient painful.

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. 4, the tong head of a kind of pneumatic type foreign body forceps described in the present embodiment, includes integrated union joint 11, bulb 12 and multiple chela 14; Described bulb is hollow structure, and bulb is connected with union joint, and union joint and described connection tube are connected; Described bulb forms the concave surface 13 of an indent spherical shape, form the angle of 120 °-150 ° between the radial direction of concave surface central point and the length direction of union joint, described multiple chela is connected to the periphery of concave surface with circumference array; Described binding clip is secondary injection molding or adopts the processing of 3D printing type, the concave part of binding clip is for having elastic rubber or plastics, binding clip remainder is rigid plastics or rubber, drives each chela to open when described concave surface is outwards heaved under gas pressure.
Described binding clip 1 is connected with a pneumatic control handle 3 by connection tube 2; The piston that described pneumatic control handle includes a piston cylinder 32 and coordinates with piston cylinder, piston is connected with end and extend out to piston rod 34 outside piston cylinder, piston cylinder front end is connected with a pipe joint 31 be connected with described connection tube, piston cylinder is connected with two draw rings 33 near the outer wall of rearward end, and piston rod rear end is connected with a throw-out collar 35; Described connection tube two ends are connected with the union joint of binding clip 1 and the pipe joint 31 of pneumatic control handle respectively.
Curved in the longitudinal direction of the outer surface of described chela 14, described chela outer surface is between the scope of bulb place sphere.Such binding clip integral surface is smooth, is beneficial to binding clip and connection tube and stretches in trachea or esophagus and can not cause scratch to in-vivo tissue.
Described union joint 11 outer surface circumferentially forms multiple anticreep convex tendon 111.Anticreep convex tendon makes union joint and connection tube be connected firmly.
When this foreign body forceps uses, after confirming foreign body position by tracheascope or gastroscope etc., binding clip is driven to rotate by rotating the pneumatic control handle strip pipe that is dynamically connected, make concave surface position alignment foreign body (between concave surface and foreign body reserved distance of being a bit larger tham chela length), the piston rod pressing pneumatic control handle produces air pressure and drives concave surface to bulge, chela is driven to open and further near foreign body, after the chela of extremely close binding clip forward portion extends and exceedes foreign body present position, the piston rod unclamping pneumatic control handle cancels air pressure, concave surface resets together with chela, so foreign body is scratched in the space that concave surface and each chela surround toward connection tube direction by chela.During this foreign body forceps gripping foreign body, the probability of foreign body generation slippage is low, is beneficial to and takes out foreign body fast, reduces patient painful.
