Description

Auxiliary instrument for rectal operation

Technical Field

The invention belongs to the technical field of rectal surgery instruments, and particularly relates to an auxiliary instrument for rectal surgery.

Background

Rectal cancer is a common malignant tumor of the digestive tract, the morbidity and mortality of the rectal cancer are increased year by year and are ranked in the first five malignant tumors of China. Modern minimally invasive surgical techniques are rapidly developed and are widely applied to laparoscopic rectal cancer radical surgery in particular.

When carrying out rectum cancer operation under the peritoneoscope, need patient to adopt the lithotomy position of head low foot height, and women's patient, especially women of child bearing age or the fertile big person of uterus hyperplasia because of lithotomy position and the big relation of uterus, the uterus often can block the rectum, influences the rectum and exposes, increases the operation degree of difficulty, influences the operation and goes on smoothly. The general solution is that an assistant holds up the uterus by a uterus lifter or passes through the abdominal wall by a needle with a rope to realize the uterine suspension. However, the existing uterine manipulator needs an assistant to lift the uterus all the time, and the assistant needs to fix the posture and continuously exert force, so that the assistant is easy to fatigue, the number of operators is increased, and medical resources are wasted. The uterus suspension mode needs to suture the uterus and the needle head to penetrate through the abdominal wall, so the injury and bleeding of the uterus and the abdominal wall are easily caused, meanwhile, the uterus suspension enables the uterus to be fixed at a certain point of the abdominal wall, the uterus suspension cannot swing left and right like a uterus lifter, and the full exposure of the operation visual field is also influenced.

In order to increase the exposure effect of the operative field of vision and reduce the operation difficulty during the process of cutting off the pathological changes of the rectum during the low-position rectal operation, an assistant is required to lift the anus in the perineum area so as to lead the pelvic floor muscles and the far-end rectum to move upwards and forwards. Reconstruction of the digestive tract is required after removal of the diseased intestinal tract. Need during the suture to dock anastomoses again with the intestinal canal that cuts off, and the current solution commonly used is that the circular anastomat of transanal insertion accomplishes the intestinal and fixes and coincide, in order to prevent the emergence that the postoperative anastomotic mouth leaks after the completion of coinciding, often need carry out the reinforcement of anastomotic mouth and sew up the embedding, nevertheless anastomotic mouth position is dark and difficult for exposing during low-order rectal surgery, still needs the assistant to lift the anus in perineum district. The long fixed posture lift makes the assistant fatigued easily and increases the consumption of the surgical staff.
