Abstract

A gun-type radioactive seed implanter for laryngopharyngeal cancer, comprising a push needle (4), a T-shaped frame (1), a turntable (2) and a conversion rod (3), wherein the bottom end of the conversion rod (3) is connected to the T-shaped frame (1). The bottom end of the vertical shaft of the profile frame (1) is rotatably connected, the transverse beam of the T-shaped frame (1) is provided with a through hole (11), and the side surface of the push pin (4) is provided with a push pin column (41), The push pin column (41) vertically passes through the push pin column track (13) and is connected to the push pin connecting hole (31) at the top of the conversion rod (3), and a conversion column is provided in the middle section of the conversion rod (3). A connecting hole (32), the turntable (2) is rotatably connected with the vertical axis of the T-shaped frame (1), and a conversion column (241) is installed on the other side of the turntable (2), and the conversion column (241) is connected to the transfer column connection hole (32). Not only can the problem of the push needle (4) being pushed too deep accidentally can be avoided, but also the return speed of the push needle (4) is faster than the push speed, and the efficiency is higher.

Description

technical field

[0001] The invention relates to the technical field of application of medical instruments for laryngopharyngeal cancer, in particular to a gun-type radioactive particle implanter for laryngopharyngeal cancer. Background technique

[0002] With the rapid development of science and technology, it has been found that some specific radioactive particles can be used to destroy tumors. Placing such radioactive particles directly in tumors can continuously emit rays and destroy cancerous tissue cells. The advantage of this method is that The tumor tissue can be killed to the maximum extent, while the normal tissue is not damaged or only slightly damaged. Generally, radioactive particles such as the isotope 125 iodine are adsorbed on a silver rod, and then a metal shell is wrapped on the outside to make small long cylindrical radioactive particles, which destroy tumors with the X-rays and R-rays they release.

[0003] In the early stage of this technology, the radio...
