Description

Gynecological laparoscopic tumor resectoscope

Technical Field

The invention relates to the technical field of medical cutters, in particular to a gynecological laparoscopic tumor resectoscope.

Background

At present, a laparoscope is a machine device which has a plurality of probes with visual functions, and after entering the abdominal cavity, a doctor performs an operation through images transmitted by the probes. The medical means has much less harm than a direct incision knife, and is a minimally invasive surgery with high safety. Tumors are new organisms formed by hyperplasia and abnormal differentiation of body cells under the action of various initiation and promotion factors. The growth of tumors is not regulated by normal body physiology, but rather destroys normal tissues and organs. According to the biological behavior of tumors, the tumors can be classified into benign tumors, malignant tumors and borderline tumors between benign and malignant tumors. Solid tumors form with definite masses, while non-solid tumors do not form with definite masses, and most of the non-solid tumors are hematological malignancies.

The invention mainly solves the problem that the traditional tumor cutter needs to cut a large wound on the abdomen and cut the wound by the hand of a doctor, and the large wound can easily cause in-vivo infection.
