Esophageal tumor marker and loading and unloading device

Abstract

The esophageal tumor marker includes a connection mechanism and an elastic metal belt. The connection mechanism is rotatably connected with two pull rods. An elastic connector is connected between the ends of the two pull rods away from the connection mechanism. The elastic metal belt is bent in an arc shape, elastic After passing through the connecting mechanism, the two ends of the metal band are fixedly connected with the end of the pull rod away from the connecting mechanism in one-to-one correspondence. The loading and unloading device includes a conduit, and a mounting rod, a lighting lamp and a camera are fixed inside the conduit, and the mounting rod is detachably connected to a connecting rod, and the connecting rod is detachably connected to an installation unit or a detachment unit; the installation unit includes a detachable connection with the connecting rod The holding seat is fixedly connected with two permanent magnets corresponding to the steel balls; the dismantling unit includes a heating element detachably connected with the connecting rod, and the heating element is fixedly connected with a hook. The marker of the present invention can be stably placed on the tumor and is not easy to fall off, and the loading and unloading device can simply and conveniently complete the installation and disassembly of the marker.

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
