Removable human body radiotherapy positioning gold mark implanting device

Abstract

The invention discloses a removable human body radiotherapy positioning gold mark implanting device. The device comprises a gold mark and a puncture needle, wherein the gold mark is arranged in a needle cylinder of the puncture needle when used, and the gold mark comprises a gold mark head and a gold mark tail connected with the gold mark head; the gold mark tail is a flexible medical thin line; the puncture needle comprises the needle cylinder and a needle core; the front end of the needle core is a needle tip, and the front end of the needle core is slightly smaller than the inner diameter of the needle cylinder; the tail of the needle cylinder is connected with a handle; the tail of the needle cylinder is a funnel-shaped cavity; and the side face of the funnel-shaped cavity is providedwith a gold mark filling hole. The gold mark tail made of the medical thin line is connected to the gold mark head, so that after the gold mark is implanted, the exterior is pasted to the body surfacethrough a medical adhesive tape, and the gold mark fixing effect is better. The flat-top needle cylinder can reduce the influence on a wound as little as possible, the best puncture effect is achieved in cooperation with the solid needle tip, the gold mark head is taken out by pulling the gold mark tail after radiotherapy of a patient is finished, and foreign matter is prevented from being left in the body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a removable human radiotherapy positioning gold label implantation device. Background technique [0002] Cyberknife, also known as "stereotaxic radiosurgery platform", also known as "network knife" or "computer knife", is the latest whole body stereotactic radiosurgery treatment equipment in the world. It can treat tumors in all parts of the body, and it only needs 3 to 5 times of irradiation to kill tumor tissues. It is the only whole body radiation that combines the advantages of "no wound, no pain, no bleeding, no anesthesia, and short recovery period". Surgical form, the patient can go home after the operation. [0003] Before cyberknife treatment, it is often necessary to implant a gold label near the tumor (that is, the target area) under image guidance, so that the position of the tumor can be tracked during cyberknife treatment, and precise treatment can be achie...

AI Technical Summary

Problems solved by technology

There are many modes of radiotherapy tracking and image registration, but for specific radiotherapy equipment such as the breathing tracking and gold label tracking modes of Cyberknife, gold labels need to be implanted in the body, and the existing gold labels are all smooth cylinders Or a tight and smooth hollow thread design. When the gold label of this design is implanted into the human body, the gold label will be lost or the gold label will be displaced due to the patient's breathing and coughing, which is easy to appear in the patient's entire treatment process. Large position deviation, leading to deviation in tumor treatment and affecting the treatment effect

At the same time, the gold label cannot be taken out after treatment, and it will have a certain impact on the human body if left in the body.
