Removable double gold marker implantation device with little damage and implantation method thereof

Abstract

The invention discloses a removable double gold marker implantation device with little damage. The removable double gold marker implantation device comprises gold markers and a puncture needle; the gold markers are arranged in a needle barrel of the puncture needle when in use; the gold markers includes gold marker heads and connecting lines connected with the gold marker heads; each gold marker head includes a first gold marker, a connecting part and a second gold marker connected in sequence; the puncture needle includes the needle barrel 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 barrel; the tail of the needle barrel is connected with a handle; the tail of the needlebarrel is sleeved with an implantation chamber; the inside of the implantation chamber communicates with the inside of the needle barrel; a guide sleeve pipe sleeves the needle barrel; and the tail ofthe guide sleeve pipe is slidably connected with a fixed disk. The damage to a body at the time of removing the gold markers can be reduced through the guide sleeve pipe, and meanwhile, a more stablesupport is provided for the gold markers in the body, and the positioning failure caused by the displacement of the gold markers is effectively prevented. The double gold marker structural design realizes the implantation of multiple gold markers at the same time, and the number of implantation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a removable double gold label implantation device with little damage. 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, patients can go home after surgery. [0003] With the development of radiotherapy technology, the development of precision radiotherapy technology has improved the curative effect of radiotherapy and reduced side effects. Before Cyberknife treatment, it is often necessary to implant gold labels near the tumor...

AI Technical Summary

Problems solved by technology

[0024] The removable gold label realizes the removal of the gold label by pulling the gold label tail out of the body. However, since the period from implanting the gold label to taking out the gold label takes about two weeks, implanting the gold label The passage left by the puncture needle will gradually heal, and the patient will have a more obvious pain when taking out the gold standard, and the implantation method is the same as the existing technology, only one gold standard can be implanted each time, and the efficiency is not high
