Problems solved by technology

[0003] This method requires the use of a tumor puncture needle to implant radioactive particles. During radioactive particle therapy, the puncture needle is first used to puncture the tumor, and after the location is determined, a radioactive particle implantation gun is connected. This type of implant gun is usually Made of metal, its weight is heavy, its structure is complicated, and the operation is cumbersome. When assembling the puncture needle, it is easy to move the position of the puncture needle and affect the operator's feel when pushing in the radioactive particles.

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, a safe implantable tumor puncture needle device includes a puncture needle tube 1 and a push rod 2. The length of the puncture needle tube 1 is 15-20 cm, the diameter of the puncture needle tube 1 is 1.0-1.2 cm, and the diameter of the push rod 2 is 0.9~1.1cm.

[0027] The push rod 2 can penetrate into the puncture needle tube 1 and can slide back and forth along the inside of the punctur...

Abstract

The invention relates to a safe implanting type tumor puncture needle device which comprises a puncture needle tube and a push rod. The push rod can penetrate into the puncture needle tube and can perform frontward and backward sliding in the puncture needle tube. The front end of the puncture needle tube is a puncture needle head. The sidewall at the back part of the puncture needle tube is provided with radioactive particle filling opening. The radioactive particle filling opening is connected with a radioactive particle chamber. The back end of the puncture needle tube is provided with a push rod insertion opening. The safe implanting type tumor puncture needle device has advantages of simple structure and reasonable design. Connection with a traditional particle implanting gun can be saved so that higher convenience and higher practicability in radioactive particle implanting treatment are realized. Therefore an operation for connecting with a heavy gun body and adverse reactions are reduced. Furthermore the safe implanting type tumor puncture needle device has advantages of saving muscle power, reducing difficulty in mastering hand feeling of an operator, etc.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a safe implantable tumor puncture needle device. Background technique [0002] Tumor is a serious disease that endangers human health, and the mortality rate is extremely high. In order to prevent and treat tumors, in recent years, radioactive particles have been implanted in medicine to treat tumors. Radioactive particles are accurately implanted into tumors through a stereotaxic system. The continuous and short-distance radiation emitted by the micro-radiation source causes the tumor tissue to be killed to the maximum extent, while the normal tissue is spared or only receives minimal damage. [0003] This method requires the use of a tumor puncture needle to implant radioactive particles. During radioactive particle therapy, the puncture needle is first used to puncture the tumor, and after the location is determined, a radioactive particle implantation gun is connect...
