Description

Technical Field

[0001] This utility model belongs to the field of biopsy needles, specifically, it relates to a cutting biopsy needle core. Background Technology

[0002] Biopsy is a technique that involves cutting, clamping, or puncturing diseased tissue from a patient's body for pathological examination when needed for diagnosis or treatment. A biopsy needle is required during the biopsy puncture process.

[0003] Chinese Patent Application No. CN202123171872.9 discloses a biopsy sampling needle, comprising: a hollow needle body; and a cutting protrusion within the needle body for residual cutting of tissue located within the needle body. Using the sampling needle provided by this invention, when the biopsy sampling needle is inserted, tissue passes through the hollow part of the needle; when the biopsy sampling needle is pulled back, the barbs cut the sample tissue, leaving the tissue on the cutting protrusion of the biopsy sampling needle. This type of biopsy sampling needle simplifies the sampling operation, eliminating the need for repeated insertion and removal of the biopsy sampling needle, and can extract more and more complete tissue samples.

[0004] However, the aforementioned existing technologies cannot precisely control the extension length and cutting range of the needle tip, which can easily cause unnecessary harm to patients during puncture biopsy and is also inconvenient for medical staff to control the needle.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A cutting biopsy needle core includes a needle tube and a silicone protective sleeve. A movable port is provided on the outside of the needle tube. The silicone protective sleeve is disposed on the outside of one end of the needle tube. An easy-to-replace sampling component is fixedly installed on the inside of the other end of the needle tube. The silicone protective sleeve is located outside the easy-to-replace sampling component. An anti-slip control component is fixed on the other end of the needle tube.

[0009] Optionally, the replaceable sampling assembly includes a spring and a first needle core, with one end of the spring fixedly mounted inside the other end of the needle tube, and one end of the first needle core fixed to the other end of the spring.

[0010] Optionally, an operating block is fixed to the outside of the first needle core, and a limit frame is fixed to the other end of the first needle core. A first magnet is fixedly installed on the bottom inner wall of the limit frame.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figures 1-4 As shown, this embodiment provides a cutting biopsy needle core, including a needle tube 1 and a silicone protective sleeve 2. A movable port is provided on the outside of the needle tube 1 to facilitate the moving and sampling of the replaceable sampling component 3. The silicone protective sleeve 2 is located on the outside of one end of the needle tube 1, and the replaceable sampling component 3 is fixedly installed on the inside of the other end of the needle tube 1. The silicone protective sleeve 2 is located on the outside of the replaceable sampling component 3, and an anti-slip control component 4 is fixed on the other end of the needle tube 1.

[0029] One application of this embodiment is as follows: Medical staff assemble the anti-slip control component 4, and then remove the silicone protective sleeve 2 set on the outer side of one end of the needle tube 1. The outer side of one end of the needle tube 1 is provided with a cutting layer. The silicone protective sleeve 2 can protect the cutting layer of the needle tube 1, reduce wear on the cutting layer, and enable quick cutting of the patient's puncture site, effectively reducing the patient's pain. The easy-to-replace sampling component 3 can not only perform puncture sampling on the patient, but also quickly replace the second needle core 308, so as to accurately control the extension length of the needle tip and the cutting range, avoiding unnecessary damage to the patient during puncture biopsy. At the same time, medical staff can control the needle tube 1 through the anti-slip control component 4, which has a good anti-slip effect.

[0030] The replaceable sampling assembly 3 includes a spring 301 and a first needle core 302. One end of the spring 301 is fixedly installed on the inner side of the other end of the needle tube 1. One end of the first needle core 302 is fixed to the other end of the spring 301. An operating block 303 is fixed to the outer side of the first needle core 302. A limiting frame 304 is fixed to the other end of the first needle core 302. A first magnet 305 is fixedly installed on the inner wall of the bottom of the limiting frame 304. A second magnet 306 is magnetically fixed to the top of the first magnet 305. The first magnet 305 and the second magnet 306 are opposite magnetic poles, so that the first magnet 305 and the second magnet 306 can attract each other. A limiting block 307 is fixed to the top of the second magnet 306. The limiting block 307 is engaged with the limiting frame 304. A second needle core 308 is fixed to one side of the limiting block 307. A biopsy sampling slot 309 is provided on the outer side of the second needle core 308. There are three biopsy sampling slots 309 to avoid interference from special circumstances and make the diagnostic results more reliable.

[0031] In this embodiment, the limiting block 307 is manually engaged inside the limiting frame 304. The first magnet 305 and the second magnet 306 can attract each other, improving the stability between the limiting block 307 and the limiting frame 304. This allows for rapid assembly of the first needle core 302 and the second needle core 308, with good stability between them. The second needle core 308 is less likely to fall off. When replacing the second needle core 308, the first needle core 302 and the second needle core 308 are pulled out from outside the needle tube 1. The second needle core 308 can be removed, reducing resource waste. When performing puncture on the patient, medical staff use the operating block 303 to pull the first needle core 302 and the second needle core 308 to move. At this time, the spring 301 is in a stretched state and has the ability to return to its original state. The biopsy sampling slot 309 can take tissue samples from the patient. After the sampling is completed, the operating block 303 is released, and under the action of the spring 301, the first needle core 302 and the second needle core 308 can move in the opposite direction to the inside of the needle tube 1, realizing the effect of puncture sampling.

[0032] The anti-slip control component 4 includes a grip 401 and a first anti-slip block 402. The grip 401 is located on the outside of the other end of the needle tube 1. The first anti-slip block 402 is fixedly installed on one side of the grip 401. A second anti-slip block 403 is fixedly installed inside the grip 401. The arrangement of the first anti-slip block 402 and the second anti-slip block 403 conforms to ergonomics and improves the comfort of medical staff. A mounting base 404 is fixed on the other side of the grip 401. A threaded groove 405 is provided on the other side of the mounting base 404. A threaded connecting post 406 is threadedly installed inside the threaded groove 405. A rotating block 407 is fixed at the other end of the threaded connecting post 406. The other side of the rotating block 407 is fixedly installed at the other end of the needle tube 1.

[0033] In this embodiment, rotating the rotating block 407 installs the threaded connecting post 406 inside the threaded groove 405, so that the needle tube 1 and the mounting base 404 can be assembled and connected together. Medical staff can use the handle 401 to control the needle tube 1, which is convenient for medical staff to operate and use. The first anti-slip block 402 and the second anti-slip block 403 improve the anti-slip effect of the handle 401 and improve the safety of puncture sampling.
