Description
Present patent application is：
It is entitled：A kind of medical foreign matter net wrench structure
Application No.：201410768557X
The applying date is：2014.12.14
Patent application divisional application.
Technical field
The invention belongs to medical instruments field, and in particular to a kind of foreign matter wrench structure for tracheae.
Background technology
Foreign matter can be hindered breathing after suction respiratory tract by mistake, can cause asphyxia even dead when serious, after aspirated foreign body
It must take out in time.Usual foreign body is to coordinate trachea foreign body forceps to be operated using airway wall, the foreign body forcepses of prior art
All it is metal material, is repeatedly used after cleaning and sterilizing, but the chela position of foreign body forcepses is generally hinge with caliper main body
Form connection is connect, link position has dead angle, it is difficult to which thoroughly cleaning is clean, there is infection risk, using effect during reuse
It is undesirable.And if the disposable cost of the foreign body forcepses of metal material is too 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.：2014104843355 patent application is solved
Above mentioned problem, the calipers of right this kind of foreign body forcepses chela when gripping foreign matter opens in front of caliper, grips some irregular shapes
Foreign matter can not be wrapped up completely when shape and the larger foreign matter even with spine of volume, to outer dragging after foreign matter is clamped
During easily injure patient tissue, using effect is undesirable.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficienciess of the prior art, providing a kind of simple in construction, make
With easy to operate, foreign matter is gripped reliable, it is to avoid the sharp foreign matter medical foreign matter net that injured patient organizes during taking-up pincers.
To realize the purpose of the present invention, it is achieved using following technical scheme：A kind of caliper knot of medical foreign matter net pincers
Structure, is integrally formed by elastic rubber material, the caliper by elliposoidal utricule and be integrally attached to utricule long axis direction one
The pipe joint b of the tubular at end is constituted, and one end that pipe joint b is connected with utricule forms one by pipe joint b and utricule point
Every partition board portion；The pipe joint b is connected with the connecting tube；Described utricule is hollow structure, ellipse residing for utricule
The major axis of ball is 1.5 times of minor axis length；An oval jaws is formed on the wall of utricule short-axis direction one end, it is described
Jaws inner circumferential form a telescoping tube；The utricule inwall uniformly forms multiple support tubes along long axis direction；Each branch
The one end of stay tube away from pipe joint b is connected, and each support tube is connected close to pipe joint b one end with partition board portion, right on dividing plate
The position of each support tube is answered to form the through hole of connection support tube and pipe joint b；The telescoping tube and at least one support tube
It is connected, and the flexible tube thickness is less than the thickness of support tube；The inwall of the telescoping tube uniformly forms spiral muscle
Bar, and the pitch of spiral rib is the 1/10 of flexible bore；Support tube is propped up utricule by air pressure effect makes part
In deployed condition, telescoping tube is acted on elongation by air pressure so that jaws is magnified, and loses air pressure rear supporting tube, telescoping tube
Support is lost, jaws is recovered to initial size.
Compared with prior art, the beneficial effects of the invention are as follows：Described caliper compact conformation is 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, the stimulation and damage for producing in-vivo tissue pipeline are small；
The utricule inwall of caliper is allowed to be maintained at deployed condition by support tube inflation, telescoping tube acted on elongation by air pressure so that
Jaws is magnified, the thickness difference of ingenious utilization telescoping tube and support tube, so that both produce two kinds of actions respectively under same air pressure,
After jaws opens alignment foreign matter and foreign matter is in the range of utricule, piston rod is replied original state rear supporting tube, stretched
Guan Jun loses support, and jaws is recovered 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, adjusting nut can be adjusted in advance to appropriate location, so according to the size of foreign matter and the size of foreign matter locational space
Disposably piston rod can be pressed on earth when gripping foreign matter, you can make jaws size appropriate, beneficial to operating time is shortened, mitigate patient
Pain.Foreign matter net pincers are applied to the foreign body of internal each position, and the rib of the telescoping tube spiral inner wall shape to stretch
Pipe axial elongation, and in telescoping tube radially because the pitch of rib is smaller, it is small that telescoping tube radially heaves amplitude, can almost neglect
Slightly, so ensure that will not cause caliper volume too to become big after telescopic tube.The big I of caliper processes different size
To adapt to different positions.
