Abstract

A tumor excision device comprises a scissor body, a first fixing mechanism and a second fixing mechanism, the scissor body comprises a first scissor body and a second scissor body which are hinged, the first fixing mechanism comprises a first fixing block and a first sliding sleeve, and a first fixing groove is formed in the side face of the first fixing block; the first sliding sleeve is arranged in the first fixing groove through a reset spring and arranged on the outer side of the cutting-off part of the first cutter body in a sliding and sleeving mode. The second fixing mechanism comprises a second fixing block provided with a second fixing groove, and the cutting part of the second scissor body is arranged in the second fixing groove in a sliding mode through a second sliding sleeve. According to the tumor excision device, the first fixing block and the second fixing block are oppositely arranged, tumor tissue is clamped and fixed in the first step before the first scissor body makes contact with the second scissor body, a doctor can independently use a single instrument to complete surgical operation, the surgical space occupied by multiple instruments is saved, and the requirement of a minimally invasive surgery is met.

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...
