Esophageal tumor marker and loading and unloading device

Abstract

The invention relates to an esophageal tumor marker, which comprises a connecting mechanism and an elastic metal belt, the connecting mechanism is rotationally connected with two pulling rods, an elastic connecting piece is connected between the ends, away from the connecting mechanism, of the two pulling rods, and the elastic metal belt is bent to be in an arc shape. The two ends of the elastic metal belt penetrate through the connecting mechanism and then are fixedly connected with the ends, away from the connecting mechanism, of the pulling rods in a one-to-one correspondence mode. A loading and unloading device comprises a guide pipe, a mounting rod, an illuminating lamp and a camera are fixedly arranged in the guide pipe, the mounting rod is detachably connected with a connecting rod, and the connecting rod is detachably connected with a mounting unit or a dismounting unit; the mounting unit comprises a retaining seat detachably connected with the connecting rod, and the retaining seat is fixedly connected with two permanent magnets in one-to-one correspondence with the steel balls; the dismounting unit comprises a heating body detachably connected with the connecting rod, and the heating body is fixedly connected with a hook. The marker disclosed by the invention can be stably retained on a tumor and is not easy to fall off, and the mounting and dismounting of the marker can be simply and conveniently completed by the mounting and dismounting device.

Description

technical field [0001] The invention relates to the field of esophageal tumor treatment equipment, in particular to an esophageal tumor marker and a loading and unloading device. Background technique [0002] The tumor marker refers to an additional device fixed on the tumor, mostly made of metal materials, after the tumor location is accurately grasped, the tumor marker can be connected with the tumor. During the subsequent radiotherapy, the tumor marker can be placed on the Shadows are formed on the film, allowing doctors to pinpoint the location of the tumor precisely, which in turn enables high-precision radiation therapy. Existing tumor markers can be divided into two types, one is implantable, that is, it needs to be implanted inside the tumor, and the other is external, that is, it needs to be fixed on the surface of the tumor. Implantable tumor markers are not suitable for some tumors that occur in shallow cavities of the human body, such as esophageal tumors, becau...

AI Technical Summary

Problems solved by technology

The marking device mainly relies on the material characteristics of the marking clip itself to clamp the esophageal tumor, and there is no structure that can continuously provide clamping force, and because the surface of the esophageal tumor is mucous membrane tissue, which is relatively slippery, its fixing effect is poor and it is easy to fall off. In addition, the marking device needs to be opened with forceps when it is removed, so the operation is more difficult, and it is easy to fall into the esophagus if it is not handled properly, and it is not suitable for deep tumors
