Description

Tumor resectoscope

Technical Field

The invention relates to the technical field of tumor treatment, in particular to a tumor resectoscope.

Background

According to the cellular characteristics of the new organism and the degree of harm to the organism, tumors are divided into two major categories, namely benign tumors and malignant tumors. Malignant tumors can be classified into carcinomas and sarcomas, and carcinomas refer to malignant tumors derived from epithelial tissues. Sarcoma refers to malignant tumor of mesenchymal tissue including fibrous connective tissue, fat, muscle, vessel, bone and cartilage tissue, such as carcinoma formed by large intestine mucosa epithelium, which is called large intestine mucosa epithelial cancer, and is called large intestine cancer for short. The skin epithelium is called skin epithelial cancer, skin cancer for short, and the like. Therefore, if a doctor says that a person suffers from cancer, it indicates that the patient is a malignant tumor; if a person suffers from gastric cancer, it means cancer formed by gastric mucosal epithelium of the patient, and if the patient suffers from gastric sarcoma, it indicates that the malignant tumor is not formed by mucosal epithelial cells, may be caused by malignant change of smooth muscle cells, or belongs to malignant lymphoma of the stomach. But it can also be said in general that he suffers from cancer;

when a tumor is treated, the tumor needs to be resected, and due to the fact that the tumor types and sizes of various patients are different, the operation methods are different in the process of resecting the tumor, the required cutting depths and ranges are different, the existing resectoscope is difficult to adapt to the tumor resection operation, and therefore a tumor resectoscope is needed.
