Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of SFB pincers caliper 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.Applicant is called in the name of JIUYUE in 2014 application on the 21st: a kind of trachea foreign body forceps and caliper, application number is: the patent application of 2014104843355 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, completely foreign body can not be wrapped up during the comparatively large foreign body even with spine of some irregularly shaped and volume of gripping, after clamping foreign body, easily injure patient tissue outward in the process pulled, result of use is undesirable.
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, avoids the Medical foreign body forceps caliper structure of sharp-pointed foreign body injured patient's tissue in taking-up process.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of SFB pincers caliper structure, include an oval caliper, described caliper is by having elastic rubber or integrally moulded, and described caliper is is structurally integrally connected and composed by the pipe joint b of tubular, the utricule of elliposoidal; Described utricule is hollow structure, and pipe joint b and described connection tube are connected; Described utricule inwall forms multiple stay pipe along long axis direction; Described utricule wall forms jaws perpendicular to the position of pipe joint b length direction, and described jaws inner circumferential forms telescoping tube, and telescoping tube is connected with stay pipe, and stay pipe is connected with pipe joint b; Described telescoping tube thickness is less than stay pipe; The inwall of described telescoping tube forms spiral-shaped rib.
Compared with prior art, the beneficial effects of the utility model are: described caliper entirety is in elliposoidal, and smooth surface is without pointed end, and the sense of discomfort produced trachea is little; The utricule inwall of caliper makes it to remain on deployed condition by stay pipe inflation, telescoping tube extends by air pressure effect thus jaws is magnified, the ingenious thickness difference utilizing telescoping tube and stay pipe, thus both produce two kinds of actions respectively under making same air pressure, open when jaws and aim at foreign body and make after foreign body is within the scope of utricule, piston rod replys original state rear supporting tube, telescoping tube all loses support, and jaws returns to initial size, and foreign body is by completely
Be wrapped within utricule, pulling out in caliper process, foreign body can not depart from, safe and convenient to use; By gum elastic or integrally moulded, easy to process, production cost is low.

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. 5, a kind of SFB pincers caliper structure described in the present embodiment, includes pneumatic control handle, caliper 3, and connects the connection tube 2 of the gentle dynamic joystick 1 of caliper; Described caliper is by having elastic rubber or integrally moulded, and described caliper is is structurally integrally connected and composed by the pipe joint b31 of tubular, the utricule of elliposoidal; Described utricule 35 is hollow structure, and pipe joint b and described connection tube are connected; Described utricule inwall forms multiple stay pipe 331 along long axis direction; Described utricule wall forms jaws 32 perpendicular to the position of pipe joint b length direction, and described jaws inner circumferential forms telescoping tube 332, and telescoping tube is connected with stay pipe, and stay pipe is connected with pipe joint b; Described telescoping tube thickness is less than stay pipe; The inwall of described telescoping tube forms spiral-shaped rib; 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, described piston rod 132 forms threaded joints, piston cylinder 11 front end is connected with a pipe joint a111 be connected with described connection tube, piston cylinder is connected with two draw rings 112 near the outer wall of rearward end, the threaded joints of piston rod is connected with an adjusting nut 12, piston rod rear end is connected with a throw-out collar 131.
During use, tracheascope is stretched into position near intratracheal foreign body together with caliper and connection tube, is observed by tracheascope, make jaws aim at foreign body; Move towards fixed handle direction by pressing described piston rod, the stay pipe of caliper is hardening under gas pressure, thus play the effect supporting utricule, described telescoping tube extends under gas pressure, thus jaws is magnified, and the position of fine setting caliper makes jaws aim at foreign body and make foreign body be in rear flank in jaws, as long as unclamp piston rod, telescoping tube loses gas pressure and recovers original shape, and foreign body is just wrapped among utricule, subsequently caliper can be taken out foreign body together with connection tube pull-out.
