Description
This patent is:
Invention entitled: a kind of surgical operation foreign body net pincers
Application No.: 2014107668269
Filing date: 2014.12.14
The divisional application of patent application.
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, bag
Include pneumatic control handle, caliper, and connect the connecting tube of the gentle dynamic joystick of caliper；Described pneumatic control handle bag
Include a piston cylinder and the piston coordinated with piston cylinder, piston connect the piston rod having end to extend out to outside piston cylinder,
Described piston rod forms threaded joints away from one end of piston, and the threaded joints of piston rod connects a regulation
Nut, piston rod rear end is connected with a throw-out collar；Piston cylinder front end is connected with one and coordinates with described connecting tube even
The pipe joint a connect, piston cylinder is connected with two symmetrically arranged draw rings near the outer wall of rearward end, and described caliper is by bullet
Property elastomeric material is one-body molded, and described caliper is by the utricule of elliposoidal and is integrally attached to the pipe of utricule long axis direction one end
The pipe joint b of shape is constituted, and described pipe joint b is connected with described connecting tube；Described utricule is hollow structure, utricule major axis
Forming a circular jaws on the wall of the other end in direction, the diameter of jaws is less than the length of the short axle of utricule；Described
Jaws inner circumferential forms a telescoping tube, and described utricule inwall uniformly forms multiple stay tubes along long axis direction；Each supports
Pipe is connected with telescoping tube away from one end of pipe joint b, each stay tube near one end of pipe joint b be connected and with pipe joint b
It is connected；Described telescoping tube thickness is less than the thickness of a stay tube, and the inwall of telescoping tube uniformly forms the rib of annular；Piston
Bar promotes piston to move air in compression piston cylinder to piston cylinder front end, compressed air by connecting tube enter stay tube and
In 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 stretched by air pressure effect
Long so that jaws is magnified, piston rod is replied original state rear supporting tube, telescoping tube and is all lost support, and jaws is recovered to initial big
Little.
As preferably: described caliper prints disposable machine-shaping by 3D.
As preferably: the 1/10-1/5 that spacing is telescoping tube internal diameter between adjacent two ribs of described telescoping tube inwall,
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, 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.

Utricule inwall uniformly forms multiple stay tubes 34 along long axis direction；Each stay tube is away from one end of pipe joint b and telescoping tube
Being connected, each 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 propping up
The thickness of stay tube, and the inwall of telescoping tube uniformly form annular rib；Piston rod promotes piston to move to piston cylinder front end
Air in compression piston cylinder, compressed air enters in a stay tube and telescoping tube by connecting tube, and a stay tube is by air pressure
Effect is propped up utricule and is allowed to be in deployed condition, and telescoping tube is by air pressure effect elongation so that jaws is magnified, and piston rod returns
Multiple original state rear supporting tube, telescoping tube all lose support, and jaws is recovered to initial size.
Described caliper prints disposable machine-shaping by 3D.Between between adjacent two ribs of described telescoping tube inwall
Away from the 1/10-1/5 for telescoping tube internal diameter, the radial section semicircular in shape of rib.Spacing between consecutive web is less, makes to stretch
Pipe is small at the deformation quantity radially produced after being driven by air pressure.
During use, fibrescope is stretched into position near the foreign body of affected part in the patient together with caliper and connecting tube, passes through
Fiber endoscopic sem observation, makes jaws be directed at foreign body；Pressing piston rod makes pneumatic control handle produce air pressure, and a stay tube for caliper exists
Under gas pressure hardening, thus play support utricule effect, described telescoping tube extends under gas pressure, so that jaws is opened
Greatly, the position of fine setting caliper makes jaws alignment foreign body and makes foreign body be in rear flank in jaws, as long as unclamping piston rod, telescoping tube loses
Going gas pressure to recover original shape, foreign body is just wrapped among utricule, subsequently that caliper is the most desirable together with connecting tube pull-out
Go out foreign body.
