Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of foreign body forceps structure for trachea.
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 by this invention 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 surgical operation foreign body net pincers of sharp-pointed foreign body injured patient's tissue in taking-up process.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of surgical operation foreign body net pincers, include pneumatic control handle, caliper, and connect the connection tube of the gentle dynamic joystick of caliper; 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 forms threaded joints away from one end of piston, the threaded joints of piston rod is connected with an adjusting nut, piston rod rear end is connected with a throw-out collar; Piston cylinder front end is connected with a pipe joint a be connected with described connection tube, piston cylinder is connected with two symmetrically arranged draw rings near the outer wall of rearward end, described caliper is one-body molded by elastic rubber material, described caliper is made up of the utricule of elliposoidal and the pipe joint b of the tubular that is integrally connected to utricule long axis direction one end, and described pipe joint b and described connection tube are connected; Described utricule is hollow structure, and the wall of the other end of utricule long axis direction forms a circular jaws, the diameter of jaws is less than the length of utricule minor axis; Described jaws inner circumferential forms a telescoping tube, and described utricule inwall evenly forms multiple stay pipe along long axis direction; Each stay pipe is connected with telescoping tube away from one end of pipe joint b, and each stay pipe is connected near one end of pipe joint b and is connected with pipe joint b; Described telescoping tube thickness is less than the thickness of stay pipe, and the inwall of telescoping tube evenly forms the rib of annular; Piston rod promotes piston and moves air in compression piston cylinder to piston cylinder front end, compressed air enters in stay pipe and telescoping tube by connection tube, stay pipe props up utricule by air pressure effect and makes it to be in deployed condition, telescoping tube extends by air pressure effect thus jaws is magnified, piston rod replys original state rear supporting tube, telescoping tube all loses support, and jaws returns to initial size.
As preferably: described caliper prints disposable machine-shaping by 3D.
As preferably: the spacing between adjacent two ribs of described telescoping tube inwall is the 1/10-1/5 of telescoping tube internal diameter, the radial section semicircular in shape of rib.
Compared with prior art, the invention has the beneficial effects as follows: described caliper compact conformation is ingenious, printed can realize time processing molding by 3D, caliper outer wall is smooth and in oval spherical, the stimulation produced in-vivo tissue pipeline during use and damage 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, jaws returns to initial size, foreign body is completely wrapped within utricule, pulling out in caliper process, foreign body can not depart from, safe and convenient to use.Adjusting nut on described pneumatic control handle can adjust the amplitude that piston rod advances, adjusting nut can be adjusted in advance to appropriate location according to the size of the size of foreign body and foreign body locational space, disposable piston rod can be pressed on earth during such gripping foreign body, jaws size can be made suitable, be beneficial to shortening operating time, alleviate patient suffering.This foreign body net pincers are applicable to the foreign body of each position in body, and in described telescoping tube, the rib of wall circular makes telescoping tube axial elongation, and it is little to heave amplitude in radial direction, and caliper volume can not be caused after can ensureing telescopic tube so too to become large.The large I of caliper processes different size to adapt to different positions.
