Description
Present patent application is:
Invention entitled: a kind of medical foreign body net clamps
Application No.: 2014107680519
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 medical foreign body net pincers of injured patient's tissue during taking out
Caliper.
For realizing the purpose of the present invention, it is achieved by the following technical solutions: the caliper of a kind of medical foreign body net pincers, institute
Stating caliper one-body molded by elastic rubber material, described caliper is by the utricule of elliposoidal and is integrally attached to utricule long axis direction
The pipe joint b of the tubular of one end is constituted, and one end that pipe joint b is connected with utricule forms one by pipe joint b and utricule
The partition board portion separated；Described pipe joint b is connected with described connecting tube；Described utricule is hollow structure, the short axle side of utricule
Forming a circle or the jaws of ellipse on the wall of one end, described jaws inner circumferential forms a telescoping tube；Institute
State utricule inwall and uniformly form multiple stay tubes along long axis direction；Each stay tube is connected away from one end of pipe joint b, respectively
Individual stay tube is connected with partition board portion near one end of pipe joint b, and on dividing plate, the position of each stay tube corresponding forms connected component
Stay tube and the through hole of pipe joint b；Described telescoping tube and one stay tube are connected, and described telescoping tube thickness is less than a stay tube
Thickness；The inwall of described telescoping tube uniformly forms the rib of annular；Described stay tube is propped up utricule by air pressure effect to be made
Be in deployed condition, telescoping tube so that jaws is magnified by air pressure effect elongation, is lost air pressure rear supporting tube, stretches
The draw all loses support, and jaws is recovered to initial size.
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, to in-vivo tissue pipeline produce stimulation and damage little；
The utricule inwall of caliper is allowed to be maintained at deployed condition by the inflation of stay tube, telescoping tube by air pressure effect elongation so that
Jaws is magnified, the ingenious thickness difference utilizing telescoping tube and a stay tube, so that both produce two kinds of actions respectively under same air pressure,
After jaws is opened alignment foreign body and made foreign body be in the range of utricule, piston rod is replied original state rear supporting tube, is stretched
Guan Jun loses support, and jaws is recovered to initial size, within foreign body is completely wrapped in utricule, is pulling out caliper process
In, foreign body without departing from, safe and convenient to use.Adjusting nut on described pneumatic control handle can adjust what piston rod advanced
Amplitude, can adjust adjusting nut to appropriate location according to the size of the size of foreign body and foreign body locational space, so in advance
Disposably piston rod can be pressed on earth during gripping foreign body, jaws size can be made suitable, be beneficial to shorten operating time, alleviate patient
Painful.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 telescoping tube
Axial elongation, and little radially heaving amplitude, it is not result in after so ensure that telescopic tube that caliper volume too becomes big.
The big I of caliper processes different size to adapt to different positions.
