Description

Telescopic antenna type tumor puncture biopsy needle

Technical Field

The invention relates to a medical article, in particular to a telescopic antenna type tumor puncture biopsy needle.

Background

Because of their diverse histological phenotypes, traditional empirical diagnosis of bone tumors based on patient history, physical examination, assisted imaging data, and the like often fails to yield a correct diagnosis, requiring histological examination for assistance. However, since bone tumors are often primarily located in bones and are deeply located, biopsy must be performed from normal soft tissues (skin, fascia, muscle, periosteum, cortical bone, medullary cavity in sequence), while the traditional puncture needles are used for taking materials, iatrogenic pollution is generated due to implantation of puncture tunnels, if important structures such as peripheral vascular nerves are polluted, or peripheral normal tissue compartments which are not affected by tumors are polluted, great difficulty is caused to later operation decisions, and even the final amputation of patients is caused. The improvement of the existing puncture needle is imperative. Therefore, a tumor puncturing biopsy needle with simple structure, safety, reliability and no pollution is sought to be a problem which needs to be solved in the society.

Disclosure of Invention

The invention aims to solve the technical problems of iatrogenic pollution caused by the traditional puncture needle or pollution to surrounding normal tissue compartments which are not violated by tumor, and the like.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: the utility model provides a scalable antenna type tumor puncture biopsy needle, includes T type handle, sleeve, shutoff nut, top stick, trephine and metal guide pin, the sleeve is scalable sleeve, sleeve and trephine's one end is connected with T type handle through the screw thread, sleeve and trephine's the other end is equipped with evenly distributed's sawtooth, be equipped with on the terminal surface of shutoff nut with sleeve matched with screw hole, the other terminal surface of shutoff nut is equipped with the recess with top stick matched with, be equipped with on the T type handle with metal guide pin matched with connecting hole; the T-shaped handle is in threaded connection with the sleeve, so that the sleeve is convenient to detach after the later operation is finished, the T-shaped handle is convenient to grasp, and the direction can be controlled better.

Further, contain 5 at least sections on the sleeve, section length is 1cm, sleeve and T type handle threaded connection, and convenient dismantlement, sleeve are telescopic sleeve, can adjust telescopic length as required.

Further, the groove is arranged in a cross-shaped structure, the connection part of the top rod and the blocking nut is in a cross-shaped structure, the connection is stable, and the top rod can also open the nut.

Further, the inside of T type handle is equipped with the internal thread, telescopic afterbody is equipped with external screw thread one, the internal screw thread cooperatees with external screw thread one, the top of trephine is equipped with external screw thread two, external screw thread two cooperatees with the internal screw thread, is detachable connection between sleeve, trephine and the T type handle, convenient equipment and dismantlement.

Further, the metal guide pin is connected with the T-shaped handle through a buckle.

Further, the bottom of the metal guide pin is pointed.

Further, the cross-sectional diameter of the telescoping sleeve is greater than the cross-sectional diameter of the trephine.

Compared with the prior art, the invention has the advantages that: the telescopic antenna type tumor puncture biopsy needle sleeve is in threaded connection with the T-shaped handle, is convenient to detach, is telescopic, and can be adjusted in length according to requirements; the telescopic sleeve in the telescopic antenna type tumor puncture biopsy needle is retracted into a tumor after the material is obtained, and the telescopic sleeve is not required to be taken out like a traditional puncture needle, so that the puncture path is prevented from being polluted by planting. The T-shaped handle is in threaded connection with the sleeve, so that the T-shaped handle is convenient to detach after the later operation is finished, the T-shaped handle is convenient to grasp, and the direction can be controlled better;

Detailed Description

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

The present invention will be described in detail with reference to fig. 1-6.

The invention provides a telescopic antenna type tumor puncture biopsy needle in specific implementation, which comprises a T-shaped handle 1, a sleeve 2, a blocking nut 3, a top rod 4, a trephine 5 and a metal guide needle 6, wherein the sleeve 2 is a telescopic sleeve, one end of the sleeve 2 and one end of the trephine 5 are connected with the T-shaped handle 1 through threads, the other ends of the sleeve 2 and the trephine 5 are provided with evenly distributed saw teeth 7, one end face of the blocking nut 3 is provided with a threaded hole 8 matched with the sleeve, the other end face of the blocking nut 3 is provided with a groove 9 matched with the top rod 4, and the T-shaped handle 1 is provided with a connecting hole 10 matched with the metal guide needle 6; the sleeve 2 comprises at least 5 sections, the length of each section is 1cm, the sleeve 2 is in threaded connection with the T-shaped handle 1, the sleeve is convenient to detach and telescopic, and the length of the sleeve can be adjusted according to requirements. The groove 9 is arranged in a cross-shaped structure, the connection part of the top rod and the blocking nut is in a cross-shaped structure, the connection is stable, and the top rod can also open the nut. The T-shaped handle 1 is internally provided with an internal thread 13, the tail part of the sleeve 2 is provided with an external thread 11, the internal thread 13 is matched with the external thread 11, the top end of the trephine 5 is provided with an external thread 12, the external thread 12 is matched with the internal thread 13, and the sleeve 2, the trephine 5 and the T-shaped handle 1 are detachably connected, so that the assembly and the disassembly are convenient. The metal guide pin 6 is connected with the T-shaped handle 1 through a buckle. The bottom of the metal guide pin 6 is pointed. The cross-sectional diameter of the telescopic sleeve 2 is larger than the cross-sectional diameter of the trephine 5.
