Umbrella-type abdominal wall hanging device used in laparoscopic operation

Abstract

An umbrella-type abdominal wall hanging device used in a laparoscopic operation comprises a hanging umbrella, a mechanical arm and a fixing rod, wherein the hanging umbrella is hung on the mechanical arm; the mechanical arm is mounted on the fixing rod; the hanging umbrella comprises a casing pipe, a needle core, a dead point ring and a hanging chain, wherein the casing pipe comprises spokes and a push-and-pull pipe; when the push-and-pull pipe slides downwards, the spokes slide to the center through proximal end joints, remote end joints and middle joints, and the umbrella-type abdominal wall hanging device is folded to be an umbrella. Due to the structure of the dead point ring, the dead point problem of the spokes during the unfolding process is solved, so that the spokes can be unfolded smoothly; spokes on the left and right sides are elastic, so that the umbrella-type abdominal wall hanging device can adapt to the arch-shaped structure of an abdominal wall well relatively, and wound of the abdominal wall can be reduced; spokes in the front and back directions are high in rigidity so as not to deform easily while bearing abdominal wall resistance. Therefore, the front part of the abdominal wall can be pulled upwards adequately to create a relatively large operation space.

Description

technical field [0001] The invention relates to the field of laparoscopic minimally invasive surgery, in particular to an umbrella-type abdominal wall suspension device for laparoscopic surgery. Background technique [0002] Laparoscopic technology has been widely used in general surgery, gynecology and urology and other disciplines. Conventional laparoscopic surgery is performed with CO 2 It is injected into the closed abdominal cavity, and the pressure of the gas to the surroundings is used to create a surgical space. But CO 2 Pneumoperitoneum can cause changes in the body's respiratory and circulatory system, fetal hypotension and hypoxia in pregnant women, reduced immune function, and dissemination of free tumor cells. Pneumoperitoneum-free technology eliminates CO 2 The adverse effect of pneumoperitoneum on the human body has important clinical significance for laparoscopic surgery for the elderly, patients with cardiopulmonary insufficiency, pregnancy, malignant tu...
