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, must take out in time behind Foreign body aspiration time serious.Generally foreign body is to use 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, being difficult to thoroughly clean up, there is infection risk when reusing, using effect is undesirable.And if the foreign body forceps single use high cost of metal material and waste resource.Filed in applicant's JIUYUE in 2014 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, completely foreign body can not be wrapped up when gripping some irregularly shaped and volume relatively greatly even with the foreign body of spine, easily injuring patient tissue during pulling outward after clamping foreign body, 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, uses easy to operate, and 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.
For realizing the purpose of the present invention, it is achieved by the following technical solutions: the caliper structure of a kind of medical foreign body net pincers, one-body molded by elastic rubber material, described caliper is made up of the pipe joint b of the utricule of elliposoidal and the tubular that is integrally attached to utricule long axis direction one end, and one end that pipe joint b is connected with utricule forms a partition board portion separated by pipe joint b with utricule；Described pipe joint b is connected with described connecting tube；Described utricule is hollow structure, major axis is minor axis length 1.5 times of elliptical shape ball residing for utricule；Forming an oval jaws on the wall of utricule short-axis direction one end, described jaws inner circumferential forms a telescoping tube；Described utricule inwall uniformly forms multiple stay tubes along long axis direction；Each stay tube is connected away from one end of pipe joint b, and each 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 the through hole of connected component stay tube and pipe joint b；Described telescoping tube is connected with at least one stay tube, and described telescoping tube thickness is less than the thickness of a stay tube；The inwall of described telescoping tube uniformly forms spiral rib, and 1/10 that the pitch of spiral rib is telescoping tube internal diameter；Stay tube is propped up utricule by air pressure effect and is allowed to be in deployed condition, and telescoping tube so that jaws is magnified by air pressure effect elongation, is lost air pressure rear supporting tube, telescoping tube and 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, by 3D print 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 a stay tube inflation, 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 is made foreign body be in the range of utricule, piston rod is replied original state rear supporting tube, telescoping tube and is all lost support, jaws is recovered to initial size, within foreign body is completely wrapped in utricule, during pulling out caliper, foreign body without departing 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, so can disposably piston rod be pressed on earth during gripping foreign body, jaws size can be made suitable, it is beneficial to shorten operating time, alleviates patient suffering.This foreign body net pincers are applicable to the foreign body of internal each position, the rib of described telescoping tube spiral inner wall shape makes telescoping tube axial elongation, and it is radially less due to the pitch of rib at telescoping tube, it is small that telescoping tube radially heaves amplitude, almost negligible, 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.
