Abstract

The invention discloses an ablation device for the oncology surgery department, and belongs to the technical field of ablation devices for the oncology surgery department. The device comprises a handheld end shell, wherein a threaded sealing piece is arranged at the right end of the handheld end shell, and the handheld end shell is in a T shape. After the device is operated and water is injected into the superficial mucous membrane layer of the esophageal tube wall, a water bag can be bulged on the superficial mucous membrane layer of the esophageal tube wall, so that an operation space is formed by the superficial mucous membrane layer of the esophageal tube wall and a muscle layer, then the superficial mucous membrane layer of the esophageal tube wall is glazed, the tumor on the superficial mucous membrane layer and the muscle layer of the wall surface of the esophagus can be quickly exposed, the problem that the tumor between the superficial mucous membrane layer and the muscle layer of the wall surface of the esophagus cannot be ablated by the existing technical means can be avoided, the tumor is separated from the muscle part, and the ablation is quicker, in addition, the condition that the esophagus is injured due to a direct ablation mode is not needed, and the operation time is saved.

Description

technical field [0001] The invention belongs to the technical field of an ablation device for oncology surgery, in particular to an ablation device for oncology surgery. Background technique [0002] The treatment of tumor ablation is divided into several types, including thermal ablation, cryoablation, and chemical ablation. Thermal ablation includes microwave ablation and radiofrequency ablation, cryoablation is argon-helium knife treatment, and chemical ablation used to be alcohol injection treatment. The main purpose of ablation is to degenerate the local lesions of the tumor. For example, if the tumor is heated to 60°C-80°C or even 100°C with microwave or radio frequency, its tissue will undergo coagulation necrosis to achieve the purpose of locally inactivating the tumor; Cryoablation is the necrosis of tumor tissue through ultra-low temperature; chemical ablation is the necrosis of most or all of the tumor tissue through chemical methods, including drugs. Therefore,...
