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 after sucking respiratory tract by mistake, can cause suffocating even dead, behind Foreign body aspiration time serious
Must take out in time.Generally foreign body is to use tracheascope to coordinate trachea foreign body forceps to operate, the foreign body forceps of prior art
It is all metal material, repeatedly uses after cleaning and sterilizing, but the chela position of foreign body forceps is usual and caliper main body is hinge
The form that connects connects, and link position exists dead angle, it is difficult to thoroughly clean up, and there is infection risk, using effect when reusing
Undesirable.And if the foreign body forceps single use high cost of metal material and waste resource.Applicant is in JIUYUE, 2014
Filed in 21 days entitled: a kind of trachea foreign body forceps and caliper, Application No.: the patent application of 2014104843355 solves
The problems referred to above, so the caliper of this kind of foreign body forceps chela when gripping foreign body opens in the front of caliper, grips some irregular shape
Completely foreign body can not be wrapped up when shape and volume are relatively greatly even with the foreign body of spine, to pulling outward after clamping foreign body
During easily injure patient tissue, using effect is undesirable.
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, makes
With easy to operate, gripping foreign body is reliable, it is to avoid sharp-pointed foreign body is the surgical operation foreign body of injured patient's tissue during taking out
Net pincers.
For realizing the purpose of the present invention, it is achieved by the following technical solutions: a kind of surgical operation foreign body net pincers knot
Structure, includes pneumatic control handle, caliper, and connects the connecting tube of the gentle dynamic joystick of caliper；Described pneumatic control
Handle includes a piston cylinder and the piston coordinated with piston cylinder, and piston connects the work having end to extend out to outside piston cylinder
Stopper rod, described piston rod forms threaded joints away from one end of piston, and the threaded joints of piston rod connects one
Individual adjusting nut, piston rod rear end is connected with a throw-out collar；Piston cylinder front end is connected with one and described connecting tube
The pipe joint a being connected, piston cylinder is connected with two symmetrically arranged draw rings, described pincers near the outer wall of rearward end
Body is one-body molded by elastic rubber material, and described caliper is by the utricule of elliposoidal and is integrally attached to utricule long axis direction one end
Tubular pipe joint b constitute, described pipe joint b is connected with described connecting tube；Described utricule is hollow structure, capsule
The major axis of elliptical shape ball residing for body is 2 times of minor axis length；A circle is formed on the wall of the other end of utricule long axis direction
Jaws, the diameter of jaws is less than the length of the short axle of utricule；Described jaws inner circumferential forms a telescoping tube, in described utricule
Wall uniformly forms multiple stay tubes along long axis direction；Each stay tube is connected with telescoping tube away from one end of pipe joint b, respectively
Individual stay tube 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 a stay tube
Degree；The inwall of described telescoping tube uniformly forms spiral rib, and the pitch of spiral rib is telescoping tube internal diameter
1/10；Piston rod promotes piston to move air in compression piston cylinder to piston cylinder front end, and compressed air is entered by connecting tube
Entering in a stay tube and telescoping tube, a stay tube is propped up utricule by air pressure effect and is allowed to be in deployed condition, and telescoping tube is by air
Pressure effect elongation is so that jaws is magnified, and piston rod is replied original state rear supporting tube, telescoping tube and all lost support, and jaws is extensive
Multiple to initial size.
As preferably: described caliper prints disposable machine-shaping by 3D.
Compared with prior art, the invention has the beneficial effects as follows: described caliper compact conformation is ingenious, is printed by 3D
Can realize being processed and formed at one time, caliper outer wall smooth and in ellipse spherical, during use to in-vivo tissue pipeline produce stimulation and
Damage little；The utricule inwall of caliper is allowed to be maintained at deployed condition by a stay tube inflation, and telescoping tube is stretched by air pressure effect
Long so that jaws is magnified, the ingenious thickness difference utilizing telescoping tube and a stay tube, so that both produce respectively under same air pressure
Two kinds of actions, after jaws is opened alignment foreign body and made foreign body be in the range of utricule, piston rod props up after replying original state
Stay tube, telescoping tube all lose support, and jaws is recovered to initial size, within foreign body is completely wrapped in utricule, is pulling out
During caliper, foreign body without departing from, safe and convenient to use.Adjusting nut on described pneumatic control handle can adjust piston
The amplitude that bar advances, can adjust adjusting nut to suitable position in advance according to the size of the size of foreign body and foreign body locational space
Put, so can disposably piston rod be pressed on earth during gripping foreign body, jaws size can be made suitable, be beneficial to shorten operating time,
Alleviate patient suffering.This foreign body net pincers are applicable to the foreign body of internal each position, and in described telescoping tube, the rib of wall circular makes
Obtain telescoping tube axial elongation, and little radially heaving amplitude, it is not result in caliper volume after so ensure that telescopic tube
Undue change is big.The big I of caliper processes different size to adapt to different positions.
