Description
Technical field
The present invention relates to a kind of medical applications, in particular to a kind of retractable aerial formula tumor aspiration biopsy needles.
Background technology
Bone tumour is because its histology phenotype is various, and tradition is looked into according to patient medical history, body, the warp of assisted image data etc.
Correct diagnosis cannot usually be obtained by testing diagnosis, need histological examination to assist.But because bone tumour is usually primary in bone, position
Set it is deep exist, it is carried out biopsy must enter from normal soft tissue (have skin successively, fascia superficialis, muscle, periosteum, cortex of bone,
Pulp cavity), traditional puncture needle can generate iatrogenic pollution while materials because of the plantation of puncture path, if important around pollution
The important features such as nervus vasculairs, or by surrounding normal not by chamber contamination between the tissue of tumor invading, the operation to the later stage
Decision causes great difficulty, even results in the consequence of the final amputation of patient.It is imperative to the improvement of current puncture needle.So
Seeking simple in structure, safe and reliable, the free of contamination tumor aspiration biopsy needle of one kind becoming this social urgent problem.
Invention content
Not the technical problem to be solved by the present invention is to iatrogenic pollution caused by traditional puncture needle or by surrounding normal
By between the tissue of tumor invading the problems such as chamber contamination.
In order to solve the above technical problems, technical solution provided by the invention is：A kind of retractable aerial formula tumor puncture work
Needle, including T-type handle, sleeve, closure nut, top stick, trepan and metallic pin are examined, the sleeve is telescopic sleeve, described
One end of sleeve and trepan is connect by screw thread with T-type handle, and the other end of the sleeve and trepan is equipped with equally distributed saw
Tooth, the end face for blocking nut is equipped with to be equipped with the matched threaded hole of sleeve, the other end for blocking nut
With the top matched groove of stick, the T-type handle is equipped with and the matched connecting hole of metallic pin；It is between T-type handle and sleeve
It is threadedly coupled, is dismantled after facilitating post-operative, T-type handle facilitates grasping, can better control direction.
Further, on the sleeve include at least five segment, the segmental length is 1cm, sleeve and T-type handle screw thread
Connection, easy to disassemble, sleeve is telescopic sleeve, can be adjusted according to the needs the length of sleeve.
Further, the groove is arranged in cross-shaped configuration, and top stick is in cross-shaped configuration with nut connecting portion is blocked,
Stable connection, while pushing up stick and can also open nut.
Further, the T-type handle is internally provided with internal thread, and the tail portion of the sleeve is equipped with external screw thread one, it is described in
Screw thread is matched with external screw thread one, and the top of the trepan is equipped with external screw thread two, and the external screw thread two is matched with internal thread, covers
To be detachably connected between cylinder, trepan and T-type handle, ease of assembly and dismounting.
Further, the metallic pin is connect by buckling with T-type handle.
Further, the bottom of the metallic pin is tip-shape.
Further, the diameter of section of the telescopic sleeve is more than the diameter of section of trepan.
The advantages of the present invention over the prior art are that：A kind of retractable aerial formula tumor aspiration biopsy needle set of the present invention
Cylinder is threadedly coupled with T-type handle, easy to disassemble, and sleeve is telescopic sleeve, can be adjusted according to the needs the length of sleeve；Structure
Simply, easily operated, the extension sleeve in a kind of retractable aerial formula tumor aspiration biopsy needle of the present invention is after materials
It bounces back in tumour, rather than as traditional puncture needle needs to take out, it is therefore prevented that puncture path is polluted by plantation.T-type handle and sleeve it
Between for be threadedly coupled, dismantled after facilitating post-operative, T-type handle facilitates grasping, can better control direction；

Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings.
In conjunction with attached drawing 1-6, describe in detail to the present invention.
The present invention provides a kind of retractable aerial formula tumor aspiration biopsy needle, including T-type handle 1, set in the specific implementation
Cylinder 2 blocks nut 3, top stick 4, trepan 5 and metallic pin 6, and the sleeve 2 is telescopic sleeve, the sleeve 2 and trepan 5
One end connect with T-type handle 1 by screw thread, the other end of the sleeve 2 and trepan 5 is equipped with equally distributed sawtooth 7, the envelope
The end face of stifled nut 3 is equipped with to be equipped with and top stick 4 with the matched threaded hole 8 of sleeve, the other end for blocking nut 3
Matched groove 9, the T-type handle 1 are equipped with and 6 matched connecting hole 10 of metallic pin；Comprising at least on the sleeve 2
5 segments, the segmental length are 1cm, and sleeve 2 is threadedly coupled with T-type handle 1, easy to disassemble, and sleeve is telescopic sleeve,
It can be adjusted according to the needs the length of sleeve.The groove 9 is arranged in cross-shaped configuration, and top stick is in nut connecting portion is blocked
