Description
Technical field
The present invention relates to medical instruments field more particularly to a kind of self-positioning locking percutaneous needles.
Background technique
Percutaneous vertbroplasty has become the good pernicious main method collapsed of centrum, can reduction of patient pain rapidly, and add
Gu lesion centrum.Most of collapse of vertebra can be by whether have primary tumo(u)r history, the typical performance of CT, MRI and ECT are before PVP
It clarifies a diagnosis.Therefore, biopsy is done first before carrying out PVP injection bone cement with clear pathological diagnosis.
Aspiration biopsy (needling biopsy, also known as needle puncture biopsy puncture biopsy) advantage is: method is easy,
Can be carried out under local anaesthesia in outpatient service, puncture it is small to the damage of tissue, bleeding is few, thus it is safer, infection chance is few,
Early stage chemotherapy or radiotherapy are not influenced, are often operated by a people.In recent years someone's needle puncture biopsy under CT, MRI ultrasound and guide of fluoroscopy
Improve success rate.Saifuddin in 2000 positions needle puncture biopsy accuracy rate with ultrasonic image and is up to 98.4%, if necessary may be used
Repeatedly puncture；Experience is insufficient or materials position is improper, is not pierced into tumor area and obtains representational tumor tissue, then it is accurate to be difficult to obtain
Conclusion, or even make the conclusion that makes mistake.According to the country, aspiration biopsy success rate is 77.5%~97.0%(average 80%).
The existing handle occupied space for puncturing outer tube is larger, can generate film making image interference, and needle in surgical procedure
Core take out when can related casing connection and go out, cause resetting again, puncture, waste time, increase risk.
Summary of the invention
In view of the drawbacks described above of the prior art, the object of the present invention is to provide a kind of interference of reduction hand fluoroscopy during operation, reduce
Repeated puncture, the risk of positioning, operation be succinct, efficiently and stable self-positioning locking percutaneous needle.
The purpose of the present invention is achieved through the following technical solutions:
A kind of self-positioning locking percutaneous needle, including puncture outer tube and puncture needle core；The puncture outer tube includes outside puncturing
Pipe handle portion punctures outer tube bar portion and threaded portion；Described one end for puncturing outer tube bar portion connects the puncture outer tube handle
Portion, the other end for puncturing outer tube bar portion connect the threaded portion；The puncture outer tube bar portion is provided with Measurement scales；It is described
It punctures outer tube handle portion and multiple hollow-out parts is set, using minimum space design structure；The threaded portion is designed with helicitic texture,
It can be locked, be locked on pedicle of vertebral arch with self-positioning screw thread；Puncture needle core includes puncture needle core handle portion, puncture needle core bar portion, with
And puncture cutting edge；One end of the puncture needle core bar portion connects the puncture needle core handle portion, the puncture needle core bar portion it is another
One end connects the puncture cutting edge；The puncture needle core handle portion uses ergonomic designs structure；The puncture cutting edge passes through
It is handled conducive to the angle design and grinding process of puncture.
Further, the point of puncture of two puncture needles forms an angle A.
Further, the angle A is preferably acute angle.
Compared with the existing technology, the features of the present invention and progress are as follows:
1, puncture outer tube of the invention uses self-positioning screw thread lock-in techniques, and it is stable, precisely to be able to maintain in art channel, greatly
It reduces needle core in operation to take out related casing connection simultaneously and go out and lead to the risk of resetting, puncture, reduces operating time.
2, puncture outer tube handle portion of the invention uses minimum space design structure, and film making image interference can be greatly reduced,
Female Luer of arranging in pairs or groups and locking mechanism operation are succinct, efficient.
3, puncture needle core handle portion of the invention uses ergonomic designs structure, and the handle operation of increasing is more easily, more
Stablize, female Luer of arranging in pairs or groups and locking mechanism operation are succinct, efficient.
4, the cutting edge that punctures of the invention passes through conducive to angle design and the grinding process processing punctured, guarantees product cutting edge of a knife or a sword
Sharp, wear-resisting, operation is light, stablizes.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-3, a kind of self-positioning locking percutaneous needle, including puncture outer tube 1 and puncture needle core 2；It punctures
Outer tube 1 includes puncturing outer tube handle portion 11, punctures outer tube bar portion 12 and threaded portion 13；The one end for puncturing outer tube bar portion 12 connects
It connects and punctures outer tube handle portion 11, puncture the other end connecting thread portion 13 of outer tube bar portion 12；It punctures outer tube bar portion 12 and is provided with survey
Measure scale；It punctures outer tube handle portion 11 and multiple hollow-out parts is set, using minimum space design structure, film making image can be greatly reduced
Interference, female Luer of arranging in pairs or groups and locking mechanism operation are succinct, efficient；Threaded portion 13 is designed with helicitic texture, can be self-positioning
Screw thread locking, is locked on pedicle of vertebral arch, and it is stable, precisely to be able to maintain in art channel, and needle core in art can be greatly reduced and take out simultaneously
