Abstract

The invention relates to the field of medical apparatus and instruments, and in particular relates to a multichannel and single-hole endoscope puncture device. The multichannel and single-hole endoscope puncture device comprises a cover, a multi-hole operation platform and a flexible passage pipe, wherein the cover is provided with a penetrating hole and an air pipe communicating with the penetrating hole; an annular containing cavity is formed in the side wall of the penetrating hole; a plurality of petal-shaped bodies are rotatably mounted in the containing cavity along the circumferential direction; the plurality of petal-shaped bodies rotate towards the inside of the penetrating hole, so that the penetrating hole is sealed; the multi-hole operation platform is provided with a pluralityof apparatus channels; the multi-hole operation platform is detachably embedded in the penetrating hole, so that the apparatus channels communicate with the penetrating hole, and the multi-hole operation platform can rotate around the axis of the penetrating hole; the passage pipe communicates with the bottom of the penetrating hole. For the multichannel and single-hole endoscope puncture deviceprovided by the invention, the multi-hole operation platform is detachably connected with the cover, so that the multi-hole operation platform can be replaced, and the risk that the diseased tissue pollutes the incision is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-channel single-hole endoscopic trocar. Background technique [0002] With the development of medical technology, minimally invasive surgery using laparoscopic technology has been increasingly popularized and used in China. In laparoscopic surgery, 2-4 holes are often used, one of which is opened on the navel of the human body or other parts of the abdomen, so as to avoid leaving long strips of scars on the patient's abdominal cavity. There are 1-3 linear scars of 0.5-1 cm, which can be said to be a minimally invasive and painful operation, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the recovery period of patients, and relatively reduces the expenditure of patients. It is a surgical item that has developed rapidly in recent years. [0003] Minimally invasive laparoscopic surgery f...
