Embodiment

[0024] Such as figure 1 with figure 2 As shown, this embodiment discloses a medical particle implantation device, which includes four components, a front handle component 1, a rear handle component 2, a push component 3, and a nut 4. Such as image 3 As shown, the front handle assembly 1 is composed of an outer tube 5, a front handle 6 and a scale 7. Such as Figure 4 As shown, the rear handle assembly is connected by the inner tube 8 and the rear handle 9; Figure 5 As shown, the pushing assembly 3 is composed of an inner core 10, a booster tube 11 and a tail handle 12. The rear end of the rear handle 9 is provided with a claw-shaped structure that can be tightened, and the claw-shaped structure is provided with a threaded neck 51 that cooperates with the loose nut 4, which can be tightened by the screw cap 4 and the booster tube on the push rod assembly 3. 11 is fixed to ensure that the rear handle assembly 2 and the push rod assembly 3 can move synchronously. A positioning...

Abstract

The invention discloses a medical particle implantation device. The medical particle implantation device comprises a front handle component, a rear handle component and a push component which are connected with one another in sequence, as well as an elastic nut used for allowing the rear handle component to be connected and fixed with the push component, wherein the front handle component comprises an outer tube and a front handle which are connected with each other; the rear handle component comprises an inner tube and a rear handle which are connected with each other, wherein the inner tube is embedded in the outer tube, and the rear handle is partially embedded in the front handle; the push component comprises an inner core, a boosting tube and a tail handle which are connected in sequence; the inner core penetrates the inner tube, the boosting tube and the rear handle in sequence; the inner tube comprises a needle head, an elastic connecting tube and an inner tube body which are connected in sequence; the caliber of the elastic connecting tube is smaller than that of the needle head and the inner tube body, so as to place the particles; and an elastic claw type structure is arranged at the tail end of the rear handle, and an external thread matched with the elastic nut is arranged outside the claw type structure.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscopic medical particle implantation device. Background technique [0002] The use of radioactive particles or chemotherapeutic particles for interventional therapy with the help of endoscopes, directly implanting radioactive particles or radiotherapy particles into the tumor body, has a good effect on the treatment of local tumors. [0003] The existing seed implantation device needs to pass through the endoscope clamp channel, which determines the length of the device is longer, the length is 1-3 meters. Conventional particle implantation devices are connected by a needle, an inner tube, and a handle. The particles are loaded from the handle end. After the needle penetrates into the tumor, the push rod is used behind the particles to push the particles into the tumor, if necessary To inject the second particle, the push rod needs to be pulled out of the handle assemb...
