Background
The main indications of percutaneous vertebroplasty are osteoporosis compression fracture and vertebral tumor, wherein the vertebral tumor is the earliest target of percutaneous vertebroplasty, and a needle biopsy is needed during the operation process in order to determine the pathology of the tumor. At present, the most common biopsy taking instrument in the market consists of a needle core part and a needle tube part, and is mainly inserted into a vertebral body through the needle tube part, and bone tissues in the vertebral body enter the needle tube through rotation or a suction device so as to realize the extraction of lesion tissues. However, in clinical feedback, the existing instruments are difficult to retain bone tissues in the needle tube during withdrawal during operation, and a sufficient amount of bone tissues cannot be obtained for pathological examination with a high probability.
In order to solve the above problems, there is a need for a biopsy instrument that ensures that more bone tissue can be harvested
Disclosure of Invention
In view of the above-mentioned defects of the prior art, the present invention is directed to a biopsy instrument for harvesting bone tissue of a vertebral body, which solves the above-mentioned problems of the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a novel centrum bone tissue biopsy instrument, includes cutting assembly, adjusting part and the outer tube subassembly of establishing from inside to outside in proper order, cutting assembly includes cutting member and handle, the cutting member near-end with handle fixed connection, adjusting part includes regulating tube and adjustment handle, the regulating tube near-end with regulating tube handle fixed connection, through the operation the regulating tube handle the regulating tube along cutting member axial slip realizes the recovery and the release of cutting member distal part, the outer tube subassembly includes outer tube and outer tube handle, the outer tube near-end with outer tube handle fixed connection, through the operation the outer tube handle the outer tube for the regulating tube with cutting member axial motion.
Further, the cutting member may be made of one or more wires or tubes.
Further, the cutting member is made of a shape memory alloy or a resilient metal alloy.
Further, the distal cutting element portion may be an L-shaped structure, a T-shaped structure, or a plurality of L-shaped structures.
Further, the outer tube distal end portion is serrated.
Compared with the prior art, the invention has the following advantages and progresses:
the instrument for taking the biopsy of the vertebral body bone tissue is simple to operate and convenient to use, and after the instrument is inserted into a puncture channel in the using process, the handle of the adjusting tube is operated to release the cutting part, then the handle of the outer tube is operated to enable the outer tube to move to be flush with the cutting part, and then the instrument is rotated to enable the bone tissue in the outer tube to be separated from the vertebral body, so that enough bone tissue is obtained to carry out pathological examination.
