Description
Technical field
The utility model relates to medical treatment detection instrument equipment technical field more particularly to a kind of percutaneous transthoracic needle biopsy needles.
Background technique
With the continuous development of medical level, in recent years by the biopsy of ultrasound-guided fine needle aspiration cytology in daily doctor
In treatment using more and more.This method is applied under ultrasonic surveillance, obtains superficial organ's tissue target mesh by proposing 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 puncture 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 the actual puncture 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 far as possible using the puncture needle with entity needle core
Exempt from above situation, but there is also certain actual application problems, need to extract entity needle core 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.
Summary of the invention

Bevel structure is limited in the through-hole other end；The special surface structure in firing button can cooperate the special oblique of needle core base tail portion afterwards
Face structure makes rear firing button deformation that bevel structure and the special surface of needle core base tail portion be promoted to contact by the extruding of external force,
To make needle core base tail portion generate plastic deformation, it is detached from the limit of through-hole, a grade face is skidded off under the effect of rear spring and then fires needle
Core print seat moves forward, when the front end face of needle core base is moved to internal sleeve assembly intermediate structure face, the special surface of needle tubing seat tail portion
Structure is in contact with the special surface structure of the front end face of needle core base, so that needle tubing seat tail portion be made to generate plastic deformation, is detached from logical
The limit in hole skids off a grade face under the effect of preceding spring and then fires needle tubing；By operating left and right press key, needle core base needle tubing seat can be made
And front and back spring reset, the horn mouth on through-hole can be such that needle core base tail portion, needle tubing seat tail portion hook-type bevel structure is deformed simultaneously
Through-hole limit is each passed through in the through-hole other end.
This programme, by complete spring force and mechanically actuated process, is quickly cut in extracting organizational process in moment
Tissue is cut, viscous glutinous and bleeding the risk of tissue is effectively reduced, whole process is easy to operate, safe, and operation doctor does not need to 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, highly-safe the utility model has the following beneficial effects: (1) is structurally reasonable；(2) user can be singlehanded
Operation.
