Abstract

The invention discloses a tumor resecting device, which comprises a scissors main body, a first fixing mechanism and a second fixing mechanism, the scissors main body comprises a hinged first knife body and a second knife body, the first fixing mechanism comprises a first fixing block and a second A sliding sleeve, the side of the first fixing block is provided with a first fixing groove, the first sliding sleeve is set in the first fixing groove through a return spring, and the first sliding sleeve is slidingly sleeved on the outside of the cutting part of the first cutter body; The second fixing mechanism includes a second fixing block provided with a second fixing groove, and the cutting part of the second cutter body is slidably arranged in the second fixing groove through the second sliding sleeve. The tumor resectator sets the first fixed block and the second fixed block oppositely, clamps and fixes the tumor tissue in one step before the first knife body and the second knife body contact, so that the doctor can use a single instrument to complete the operation, saving It reduces the surgical space occupied by multiple instruments and meets the needs of minimally invasive surgery.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a tumor resecting device. Background technique [0002] Tumor tissue differs from its normal tissue in varying degrees in terms of cell morphology and tissue structure. This difference is called atypia, and atypia is the morphological manifestation of abnormal tumor differentiation. A small atypia indicates a high degree of differentiation, and a large atypia indicates a low degree of differentiation. Distinguishing the size of this atypia is the main histological basis for diagnosing tumors and determining benign and malignant tumors. The atypia of benign tumor cells is not obvious, and is generally similar to its source tissue, while malignant tumors often have obvious atypia. [0003] At present, the principle of tumor treatment is comprehensive treatment based on surgery, supplemented by symptomatic treatment according to the condition. Surgery refers to the remo...
