Description
Technical field
The present invention relates to medical treatment detection instrument equipment technical field more particularly to a kind of percutaneous transthoracic needle biopsy needles.
Background technology
With the continuous development of medical level, in recent years by the biopsy of ultrasound-guided fine needle aspiration cytology in daily doctor
Application in treatment is more and more.This method is applied under ultrasonic surveillance, and superficial organ's tissue target mesh is obtained by putting forward slotting mode
Mark cell and carry out pathological diagnosis, such as mammary gland, thyroid gland, kidney, liver, lymph node, be early diagnosis target it is good it is pernicious most
Fast, the easy method with safety.For previous histology biopsy, with damaging, small, risk is small, result equally may be used
By the advantages that.This is related to a very important tool --- puncture needle.
Presently used puncture needle is hollow superfine round tube shape structure, the outer diameter ruler that 14~25G of outer diameter is corresponding in turn to
Very little is 2.1mm~0.4mm, can be furnished with entity needle core, and entity needle core just fills the hollow space of puncture needle, the work of entity needle core
With being to prevent tissue debris and other non-target destination organizations from entering in the hollow space of puncture needle in piercing process, interference or shadow
Ring diagnostic result；Why the biopsy of Ultrasound-guided Biopsy needle cytology is safe, is because the puncture path of puncture needle can begin
Eventually operation doctor direct-view under carry out, in practical piercing process, operation doctor must a hand handle hold probe, another hand is held
Puncture needle, if being used without the puncture needle of entity needle core, tissue debris or non-target target cell if, easily enters puncture
In needle, interference or the accuracy for influencing pernicious judgement good to target；If can be kept away as possible using the puncture needle with entity needle core
Exempt from the above situation, but there is also certain actual application problems, and entity needle core need to be extracted when puncture needle reaches target, if
Operation doctor abandons the holding to puncture needle to extract entity needle core at this time, and needle core is put into safe place, due to soft group
The flexibility and elasticity knitted, puncture needle will be displaced, and damaged the risk of vital tissue and organ around target and increased
Add.
Invention content
The present invention be in order to solve existing defect problem during existing puncture needle use, provide it is a kind of reasonable for structure,
It is safe, the disposable percutaneous transthoracic needle biopsy needle of user's one-hand operation.
To achieve the goals above, the present invention use following technical scheme, a kind of percutaneous transthoracic needle biopsy needle, including needle tubing and
Needle core, further includes case top lid, button, torsional spring, bearing chuck and shell lower cover, the bearing chuck respectively with torsional spring, needle
Pipe connects, and the torsional spring is connect with case top lid, shell lower cover, and the needle core is connect with case top lid, shell lower cover, institute
The button stated is connect with case top lid.
Preferably, on the needle tubing have scale display label, the needle tubing using special ultrasonic development handle and
Surface affinity processing.Needle tubing use can cause at the processing of special ultrasonic development and surface affinity of surface roughness change
Reason, is to increase needle tubing band transmission catoptric imaging development effect under ultrasound；
Preferably, the needle core head end is equipped with inclined-plane and passes through milled processed, the needle core material uses at rigidity
Reason.Needle core head end is equipped with inclined-plane and is to increase the puncture force of needle core piercing by milled processed, and needle core material is using rigidity
When encountering harder tissue, needle core occurs bending and deformation when processing is to prevent from being pierced into.
This programme needle tubing tail end Special-Shaped Surface (tubaeform) is opposite with the rear end face profiled holes (speaker hole) of bearing chuck to be connect,
Case top lid is connect with shell lower cover, and needle core and torsional spring assemble therebetween with needle tubing component, the side of button and case top lid
Structure connects, and state of the bearing chuck in component, the structure connection of bearing chuck and torsional spring can control to can control torsional spring in group
Compressive state in part；
This programme, by complete spring force and mechanically actuated process, is quickly cut in extracting organizational process in moment
Tissue is cut, effective to reduce viscous glutinous and bleeding the risk of tissue, whole process is easy to operate, safe, and operation doctor need not abandon
Puncture needle core is extracted to the holding of puncture needle, puncture needle is avoided to be displaced, damages vital tissue and organ around target
Risk substantially reduce.
Therefore, the present invention has the advantages that：(1) reasonable for structure, it is safe；(2) user's one-hand operation.

Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 6, a kind of percutaneous transthoracic needle biopsy needle, including needle tubing 5 and needle core 6, further include case top lid 1,
Button 2, torsional spring 3, bearing chuck 4 and shell lower cover 7, bearing chuck 4 are connect with torsional spring 3, needle tubing 5 respectively, on torsional spring 3 and shell
Lid 1, shell lower cover 7 connect, and needle core 6 is connect with case top lid 1, shell lower cover 7, and button 2 is connect with case top lid 1；
There is scale display label, needle tubing 5 is handled using special ultrasonic development and the processing of surface affinity on needle tubing 5；
6 head end of needle core is equipped with inclined-plane and passes through milled processed, and 6 material of needle core uses rigid treatment；
Specifically used process is that this programme detachably assembles, and when assembling, needle tubing 5 is connect with 4 tail portion of bearing chuck, is turned round
Spring 3 is connect with 4 endoporus of bearing chuck, torsional spring 3 is connect with case top lid 1, shell lower cover 7, by needle core 6 and case top lid 1, shell
Body lower cover 7 connects, and button 2 is connect with case top lid 1, constitutes a kind of accurate fast and safely percutaneous transthoracic needle biopsy needle instrument；
When loading, as shown in Fig. 2, bearing chuck 4, which is stirred to the right, makes torsional spring 3 be in compressive state, promoting button 2 forward
Lock bearing chuck 4；
When sampling, as shown in figure 3, by the above-mentioned component to have loaded, under the guiding of ultrasonic probe, punctures skin and reach
Taken tissue location, button 2 is pushed backward makes torsional spring 3 restore to rotate with dynamic bearing chuck 4 under natural conditions, bearing chuck
The 4 linkage rotations of needle tubing 5 are formed with needle core 6 to rotate, and reaches the function of circumgyration incision.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
