Description

A kind of medical foreign matter net pincers

Present patent application is:

It is entitled:A kind of medical foreign matter net pincers

Application No. is:2014107680519

The applying date is:2014.12.14

Patent application divisional application.

Technical field

The invention belongs to medical instruments fields, and in particular to a kind of foreign matter wrench structure for tracheae.

Background technology

Foreign matter can be interfered breathing after accidentally sucking respiratory tract, can cause asphyxia even dead when serious, after aspirated foreign body It must take out in time.Usual foreign body is operated using airway wall cooperation trachea foreign body forceps, the foreign body forceps of the prior art All it is metal material, is repeatedly used after cleaning and sterilizing, but the chela position of foreign body forceps is usually hinge with caliper main body Form connection is connect, there are dead angles for link position, it is difficult to thoroughly clean up, there are infection risk, using effects when reuse It is undesirable.And if the disposable cost of the foreign body forceps of metal material is excessively high and waste of resource.Applicant is in September, 2014 It is entitled filed in 21 days:A kind of trachea foreign body forceps and caliper, application No. is:2014104843355 patent application solves The above problem, the calipers of right this kind of foreign body forceps chela when grip foreign matter grip certain irregular shapes in the front of caliper opening Foreign matter cannot be wrapped up completely when shape and the larger foreign matter even with spine of volume, to outer dragging after clamping foreign matter It is easy to injure patient tissue in the process, using effect is undesirable.

Invention content

The technical problem to be solved by the present invention is to:In view of the deficienciess of the prior art, offer is a kind of simple in structure, make With easy to operate, gripping foreign matter is reliable, avoids the sharp foreign matter medical foreign matter net that injured patient organizes during taking-up pincers Caliper.

Purpose to realize the present invention, is achieved using following technical scheme:A kind of medical foreign matter net pincers, feature exist In:It include the connecting tube of the gentle dynamic control handle of pneumatic control handle, caliper, and connection caliper;The pneumatic control Handle includes being connected with the work that end is extend out to outside piston cylinder on piston there are one piston cylinder and the piston that coordinates with piston cylinder Stopper rod, the one end of the piston rod far from piston form threaded joints, one are connected on the threaded joints of piston rod A adjusting nut, piston rod rear end are connected with a throw-out collar;There are one piston cylinder front end integrally connecteds and the connecting tube The pipe fitting a of mating connection, there are two symmetrically arranged draw ring, the pincers for outer wall integrally connected of the piston cylinder close to rear end Body is integrally formed by elastic rubber material, the caliper by elliposoidal utricule and be integrally attached to utricule long axis direction one end The pipe fitting b of tubular constitute, and there are one by pipe fitting b and utricule separation for one end moldings for connect with utricule of pipe fitting b Partition board portion;The pipe fitting b is connected with the connecting tube;The utricule is hollow structure, utricule short-axis direction one There are one the clamping opening of round or ellipse for molding on the wall surface at end;The utricule inner wall forms telescoping tube, and telescoping tube and folder The distance at mouth edge is 1-1.5 times of flexible pipe outside diameter;The utricule inner wall uniformly forms multiple support tubes along long axis direction; The one end of each support tube far from pipe fitting b is connected, and each support tube is connected close to one end of pipe fitting b with partition board portion, every The position that each support tube is corresponded in plate portion forms the through-hole of connection support tube and pipe fitting b;The telescoping tube and a branch Stay tube is connected, and the flexible tube thickness is less than the thickness of support tube;The inner wall of the telescoping tube uniformly forms annular Rib;Piston rod push piston to piston cylinder front end movement compression piston cylinder in air, compressed air by connecting tube into Enter in support tube and telescoping tube, support tube is propped up utricule by air pressure effect and is allowed to be in unfolded state, and telescoping tube is by air Pressure effect elongation is to make clamping opening magnify, and piston rod replys original state rear supporting tube, telescoping tube loses support, and clamping opening is extensive Again to initial size;

The caliper is processed and formed at one time by 3D printing;Between between the two neighboring rib of flexible inside pipe wall Away from the 1/10-1/5 for the bore that stretches.

Compared with prior art, the beneficial effects of the invention are as follows:The caliper is compact-sized ingenious, passes through 3D printing It can be achieved to be processed and formed at one time, caliper outer wall is smooth and spherical in ellipse, and the stimulation and damage for generate in-vivo tissue pipeline are small; The utricule inner wall of caliper is allowed to be maintained at unfolded state by support tube inflation, and telescoping tube is by air pressure effect elongation to make Clamping opening is magnified, the ingenious thickness difference using telescoping tube and support tube, to make the two under same air pressure generate two kinds of actions respectively, After clamping opening opens alignment foreign matter and foreign matter is made to be within the scope of utricule, piston rod replys original state rear supporting tube, stretches Guan Jun loses support, and clamping opening is restored to initial size, and foreign matter is completely wrapped within utricule, is pulling out caliper process In, foreign matter is without departing from safe and convenient to use.Adjusting nut on the pneumatic control handle can adjust piston rod advance Amplitude can adjust adjusting nut in advance to appropriate location, in this way according to the size of foreign matter and the size of foreign matter locational space It can be disposably by piston rod by earth when gripping foreign matter, you can keep clamping opening size appropriate, be conducive to shorten operating time, mitigate patient Pain.Foreign body of the foreign matter net pincers suitable for internal each position, the rib of the flexible inside pipe wall annular make telescoping tube Axial elongation, and it is small in radial amplitude of heaving, caliper volume will not be caused excessively to become larger after capable of ensureing telescopic tube in this way. Caliper size can process different size to adapt to different positions.
