Biopsy puncture needle component used for orthopedics department

Abstract

The invention relates to a biopsy puncture needle component used for an orthopedics department. The biopsy puncture needle component used for the orthopedics department comprises a pipe sleeve, a puncture needle, a depth probe and a bone specimen clamping needle, wherein the pipe sleeve comprises a first handheld part and a needle tube, a first groove is formed in the upper part of the first handheld part, a boss is formed in the center of the first groove, a spiral sliding chute is formed outside the boss, one hole is formed in the center of the boss, a second groove group is arranged at the lower part of the handheld part and is used for holding the handheld part, the needle tube is fixed in the center of the second groove group and is communicated with the hole, the puncture needle comprises a first needle guard and a first needle core, a cone is arranged at the top of the first needle core, the depth probe comprises a second needle guard and a second needle core, the top of the second needle core is a plane, the bone specimen clamping needle comprises a third needle guard and a third needle core, and multiple clamping pieces are arranged at the top of the third needle core. The biopsy puncture needle component used for the orthopedics department has the beneficial effects that structure is simple, using effect is good, and the biopsy puncture needle component is innovation in needle biopsy instruments.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a biopsy puncture needle assembly for orthopedics. Background technique [0002] At present, for human bony lesions such as various bone tumors, it is usually necessary to puncture a biopsy needle into the lesion in the body to take a living bone specimen, send the specimen to a pathological laboratory for processing, and then perform histopathological examination to confirm the diagnosis. The existing percutaneous bone biopsy needle needs to swing off-axis in a small range to break the tissue when taking materials. The defect is that it causes great trauma to the patient (stress fracture, bone crack), and it is easy to cause the failure of taking materials. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an orthopedic biopsy puncture needle assembly with less trauma to the patient (no off-axis swing), higher ...

AI Technical Summary

Problems solved by technology

Existing percutaneous bone biopsy needles need to swing off-axis in a small range to break up the tissue when taking materials. The disadvantages are: large trauma to the patient (stress fractures, bone cracks), and easy failure of taking materials.
