Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a device for taking a specimen of a tumor patient through a natural cavity under a laparoscope.
Background
Tumor refers to a new organism formed by local tissue cell proliferation under the action of various tumorigenic factors, because the new organism mostly presents space-occupying block-shaped protrusions, which is also called neoplasm.
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 he may also be said to suffer from cancer in general.
To the treatment of tumour, some need to excise the pathological change position, but to some internal tumour of patient, generally adopt the pliers directly to press from both sides to get with the operation mode, but this method generally is great to the patient injury, for example, colorectal cancer patient needs the big intestines of intercepting disease position, adopts the pliers to press from both sides to get extremely troublesome, not only can cause very big wound injury to the patient, has also increased the degree of difficulty in the operation.
