Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention is a puncture needle implanted with radioactive particles under endoscope for digestive tract tumors, such as figure 1 As shown, it includes a puncture part, a connection part, an operation part and an implant part.

[0022] Among them, the puncture part such as figure 2 As shown, it includes a cylindrical puncture needle sheath 1 made of stainless steel, in which a through particle implantation channel 2 is arranged in the axial direction, and one end of the puncture needle sheath 1 is a needle-shaped piercing end 11 The length of the puncture needle outer sheath 1 is 6.0mm, and its inner diameter matches the cylindrical structure of known radioactive particles. The diameter and length of the puncture needle outer sheath 1 are about 0.8mm and 4.5mm respectively.

[0023] Connecting parts such as image 3 As s...

Abstract

The invention discloses an active particle implantation puncture needle under a digestive tract tumor endoscope. The active particle implantation puncture needle comprises a puncturing part, a connecting part, an operating part and an implanting part, wherein the puncturing part comprises a puncture needle sheath and a particle implantation channel. The connecting part comprises a far-end metal shell tube with the puncture needle fixedly connected to one end thereof; the far-end metal shell tube is fixedly connected with a near-end metal shell tube through a middle bendable spiral metal shell tube; and the other end of the near-end metal shell tube is fixedly connected with the operating part. The operating part comprises an operating cap, a particle implantation cabin and a particle implantation channel inlet. The implanting part comprises a pushing rod and an operating handle, both of which are connected fixedly. The active particle implantation puncture needle under the digestive tract tumor endoscope, disclosed by the invention, is an active particle implantation instrument under the endoscope for local radiotherapy of late-stage gastrointestinal carcinoma and has the advantages of operation convenience and good safety.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to instruments for puncturing human organs or tissues and implanting radioactive particles, in particular to a puncture needle for implanting radioactive particles under endoscopy for digestive tract tumors. Background technique [0002] At present, in clinical practice, after implanting radioactive particles into lesions of unresectable advanced pancreatic cancer, some patients have achieved obvious benefits and significant curative effects. For patients with gastrointestinal tumors such as advanced esophageal cancer, gastric cancer, pancreatic cancer, and colorectal cancer who cannot undergo surgery, radiotherapy, and chemotherapy, on the premise of fully evaluating the depth and extent of cancerous lesions after preoperative imaging reconstruction of lesions, Implanting radioactive particles at a certain density by means of endoscopy or ultrasound endoscopy can inhibit the ...
