Description
Technical field
The present invention relates to area of medical devices, and in particular to a kind of sting device.
Background technology
As pleural effusion and pneumothorax are clinically common diseases, the use for the pneumothorax puncture needle of two class disease surgeries
Widely.Except the blood caused by thoracic trauma, pneumothorax, outside Thorax operration pleural effusion, in recent years, due to lung cancer morbidity rate and lung
The incidence of disease of tuberculosis increases year by year so that cancerous hydrothorax patient and the patients with pleural caused by tuberculosis largely increase, this two class
Patient generally requires repeated multiple times thoracentesis, so that clinically being greatly increased to the demand of pneumothorax puncture needle.
Traditional puncturing operation is cumbersome, due to uncontrollable paracentesis depth, easily causes hemothorax, pneumothorax, thoracic cavity infection
Etc. complication, and puncture needle due to length it is too small, in operation such as disunity is placed and easily causes loss.
The content of the invention
It is simple to operate it is an object of the invention to provide a kind of sting device, procedure efficiency is improved, mitigates the pain of patient
Hardship, have a safety feature, needle length in insertion body can be controlled.
The present invention provides a kind of sting device, including, puncture cannula and puncture needle, puncture cannula one end are kept off provided with the first body
Body；Scale is provided with outside puncture cannula；Puncture needle is provided with the second block body, punctures handle and puncture portion；Handle is punctured to be provided with
Through hole；Puncture cannula is sheathed on puncture needle away from puncture handle one end.The second block body on puncture needle and the on puncture cannula
One block body is engaged, and puncture cannula is fixed on puncture needle, is punctured when handle is conveniently performed the operation and is operated.Puncture and set on handle
There is through hole, conveniently hung during operation, and the position that puncture needle is placed is found during convenient use.
In some embodiments, the length of puncture cannula is 10cm, and internal diameter 6mm, the length in puncture portion is 10cm, interior
Footpath is 4mm.Puncture cannula is facilitated to be set on puncture needle.
In some embodiments, puncture portion is provided with multiple puncture tips, and puncture tip is used to be punctured.Facilitate hand
Puncture needle is passed through into thoracic cavity during art, and multiple puncture tips are advantageous to quick puncture, mitigate patient suffering, will not be because only that one
Individual tip, so as to puncture difficulty, so as to cause to puncture time length, taken to patient painful for a long time.
In some embodiments, puncture cannula uses polypropylene material.Because polypropylene surface hardness is low, conveniently cut
Cut.
In some embodiments, the start mark length of scale is 3cm, and end length is 8cm.Because puncture needle enters
People's body length is necessarily more than 3cm, so start mark length is 3cm, facilitating medical work, person uses, will not be because of labeled
It is more, upset medical work person's sight.Operate simpler.
In some embodiments, puncture handle and be provided with anti-slip veins.Anti-slip veins can increase the stability that operation is implemented,
Will not be because of medical work person's rubber sleeve, repeated puncture.

Fig. 2 is a kind of puncture portion structural representation of sting device of one embodiment of the present invention.
Fig. 3 is a kind of puncture cannula structural representation of sting device of one embodiment of the present invention.
Fig. 4 is that a kind of a kind of sting device of new embodiment of this practicality implements schematic diagram.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail explanation.
The present invention relates to the present invention to provide a kind of sting device, as shown in figure 1, including puncture cannula 1 and puncture needle 2, wearing
Thorn sleeve pipe 1 one end is provided with the first body block body 11；The outside of puncture cannula 1 is provided with scale 12；Puncture needle 2 be provided with the second block body 21,
Puncture handle 22 and puncture portion 23；Puncture handle 22 and be provided with through hole 221；Puncture cannula 1 is sheathed on puncture needle 2 away from puncture hand
The one end of handle 22.The second block body 21 on puncture needle 2 and the first gear mates on puncture cannula 1, consolidate puncture cannula 1
It is scheduled on puncture needle 2, punctures and operated when handle 22 is convenient to perform the operation.Puncture handle 22 and be provided with through hole 221, conveniently hanged during operation
Hang, because the instrument needed during operation is a lot, when the instrument of searching, substantially increases operating time, worn on handle logical
Hole 221, can be suspended on fixed position, find puncture needle 2 during convenient use.So as to greatly reduce operating time.Puncture set
The outside of pipe 1 is provided with scale 12, can control the length punctured in insertion body, simple to operate, will not be dredged because of user
Suddenly, chest is worn out, secondary injury is caused to patient.
The length of puncture cannula 1 is 10cm, and internal diameter 6mm, the length in puncture portion 23 is 10cm, internal diameter 4mm.Conveniently wear
Thorn sleeve pipe 1 is set on puncture needle 2.
As shown in Fig. 2 puncture portion 23 is provided with multiple puncture tips 231, puncture tip 231 is used to be punctured.It is convenient
Puncture needle 2 is passed through into thoracic cavity during operation, and multiple puncture tips 231 are advantageous to quick puncture, mitigate patient suffering, will not be because of
An only tip, so as to puncture difficulty, so as to cause to puncture time length, taken to patient painful for a long time.The front end of puncture needle 2
For tip, improve and puncture efficiency, reduce the operating time, puncture needle 2 is conveniently passed through into thoracic cavity during operation, due to puncturing in operation
The internal diameter of sleeve pipe 1 is small, to the wound of patient just very little.
Puncture cannula 1 uses polypropylene material.Because polypropylene surface hardness is low, convenient cutting.When in use, it is right first
Patient carries out B ultrasound, detects chest thickness, puncture cannula 1 is cut into respective thickness afterwards.Controlled when so conveniently performing the operation
Paracentesis depth.
As shown in figure 3, the start mark length of scale 12 is 3cm, end length is 8cm.Because puncture needle 2 enters human body
Length is necessarily more than 3cm, so start mark length is 3cm, facilitating medical work, person uses, and will not disturb because of labeled more
Random medical work person sight.Operate simpler.
Puncture handle 22 and be provided with anti-slip veins 222.Anti-slip veins can increase the stability that operation is implemented, will not be because of medical
Worker's rubber sleeve, repeated puncture.
As shown in figure 4, during operation, B ultrasound is carried out to patient first, chest thickness is detected, afterwards cuts puncture cannula 1
Respective thickness is cut, puncture needle 2 is set on puncture cannula 1, is held on the anti-slip veins 222 for puncturing handle 22, by puncture needle 2
From patient thoracic cavity anchor point vertically into thoracic cavity, after puncture needle 2 enters thoracic cavity, puncture needle 2 is taken out.By the puncture needle 2 of taking-up
Specified location is suspended on, in case being continuing with.Puncturing operation terminates.
