Description

Tumor resection device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to tumour resection device.

Background

Tumor tissue is composed of cancer cells and stroma, and cancer cells are abnormally proliferating cells transformed from normal cells. Tumors can occur in many organs and tissues of the human body. The tumor is classified into benign tumor and malignant tumor according to the size of the harm of the tumor to human body and the growth characteristics of the tumor. Benign tumors grow slowly and are in swelling growth, complete envelopes are usually arranged on the surfaces of the benign tumors, the benign tumors have fewer general symptoms except local symptoms, do not infiltrate into surrounding tissues and transfer to the whole body, and the benign tumors have less harm to organisms. Malignant tumor grows rapidly, often infiltrates into surrounding tissues during growth, has few envelopes on the surface, often transfers to the whole body and has great harm to the organism.

Surgery is a means of local treatment, and for tumors that do not metastasize and spread, surgery is performed on the patient to remove the tumor tissue. Generally need fix the tumour with centre gripping instruments such as tweezers earlier in the tumour excision operation, then with the operation sword excision tumour, the in-process of tumour centre gripping is less because of the front end area of tweezers, and medical personnel hardly accurate control centre gripping dynamics makes the tumour take place the damage easily, can't guarantee the integrality of tumour, in case the tumour is damaged, the risk of tumour planting and diffusion can rise greatly.

CN207055529U discloses a tumour operation is with excising device, including two sets of tong arms, it is two sets of the tong arm sets up about central transverse line symmetry, and is two sets of the nodical department of tong arm is connected through the pivot, and is two sets of anti-skidding rubber pad is all installed to the inside wall of tong arm left end, the rear side the left end of tong arm outer wall has through the round pin hub connection dials the board, the left end of dialling the board is connected with the cutting knife, the front side thumb catching groove is installed at the top of the right side stalk portion of tong arm, the rear side finger clamping bar is installed to the bottom of the right side stalk portion of tong arm, and is two sets of reset spring is installed between the tong arm.

The tumour cutting is realized simultaneously to the centre gripping dynamics of above-mentioned patent control tumour, but exposes the cutting knife in the outside easily with the tumour fish tail at the in-process of centre gripping tumour, triggers tumour planting diffusion, increases the risk of operation failure.
