Technical Field

The invention belongs to the technical field of medical treatment, and particularly relates to a telescopic tumor clamping device.

background

The tumor tissue is composed of parenchyma and stroma, and the tumor parenchyma is tumor cells, is a main component of the tumor and has tissue source specificity. It determines the biological characteristics of the tumor and the specificity of each tumor. The tissue origin of various tumors is generally identified according to the parenchymal morphology of the tumor, classification, naming and histological diagnosis of the tumor are performed, and the benign and malignant degree of the tumor and the malignant degree of the tumor are determined according to the differentiation maturity degree and the size of the heterogeneity.

surgical treatment of tumors is one of the most widely and effectively applied clinical treatments, and the therapeutic effect thereof is clinically recognized. When operation treatment tumour, need use the tumour to press from both sides the device and separate tumour tissue, but when clinical application, the current tumour is pressed from both sides and is got separator and can't carry out telescopic length adjustment according to the position of tumour, the implementation of the tumour operation of being not convenient for, operability and suitability are poor.
