Figure 1 is a schematic diagram of the structure of the existing implant needle for injecting nuclei. It consists of a needle 1', a push rod 2' and a jacket 3'. When in use, the nuclei 4' must be put in one by one, one by one. It is used by pushing the push rod 2', which is inconvenient, slow and inaccurate; at the same time, the push rod 2' is rigid, and it is inconvenient to enter the human cavity

Embodiment Construction

[0015] Referring to Figure 2 and Figure 3, the present invention is mainly composed of needle 12, needle tube 5, main body 6, push rod 2, positioning device I, stepper 8, pawl 9, handle 10 and homing device II, wherein positioning device I It can be a positioning stake 7, and the homing device II can be a homing button 11. The needle 12 is installed on the needle tube 5, and a retention device III is provided at the connection between the front end of the needle tube 5 and the needle 12. The retention device III is an elastic retention device or a rubber retention cap; the main body 6 is mounted on the handle 10 and installed inside There are push rod 2, positioning stake 7, stepper 8 and pawl 9. The needle tube 5 is flexible and can contain multiple nuclei 4 inside, and a retention device III is provided at the front end to prevent the nucleus 4 from falling out by itself; the needle tube 5 can be bent and can enter the human body cavity through the working channel of the endosco...

Abstract

The present invention is planter for operation treatment to tumor. The planter is provided with needle tube, main body, locator, stepper, ratchet, handle and re-locator. Inside the main body on the handle, there are push rod, locator, stepper and ratchet; and on the stepper, the push rod and the re-locator are installed. Each pressing of the handle will push out one nucleon, so that the planter may be used to push out nucleon continuously and accurately, being superior to available planting needle.

Description

Technical field [0001] The invention relates to an implanter, which belongs to medical equipment, and is a bendable continuous implantation device, which is suitable for surgical treatment of human tumors in medicine. Background technique [0002] In the prior art, in order to eliminate human tumors, it is one of the important conditions for tumor elimination to conveniently and accurately implant a tiny radioactive source, namely nucleus, into the desired location. Figure 1 is a schematic diagram of the structure of a conventional implant needle for nucleus injection. It consists of a needle 1', a push rod 2'and a jacket 3'. When using, the nuclei 4'must be put in one by one, one by one The ground is used by pushing the push rod 2', which is inconvenient to use, slow and not accurate enough; at the same time, the push rod 2'is rigid and it is inconvenient to enter the body cavity. Summary of the invention [0003] The technical problem to be solved by the present invention is t...
