Abstract

The invention discloses renal artery blocking forceps capable of adjusting pressure. The renal artery blocking forceps comprise an outer cylinder, forceps arms, an adjusting assembly, an air bag and an air pump, wherein the two clamp arms are hinged to the front end of the outer cylinder, the adjusting assembly comprises a movable cylinder, an inner cylinder, a supporting rod and a spring, the movable cylinder is located in the outer cylinder, the front end of the movable cylinder is in an open horn mouth shape and sleeves the tails of the clamp arms, the inner cylinder is fixedly mounted in the movable cylinder, and the spring is located in the inner cylinder; one end of the supporting rod is provided with a disc and abuts against the part between the tails of the two clamp arms, and the other end of the supporting rod is inserted into the inner cylinder and abuts against one end of the spring; and the air bag is located in the outer cylinder and located behind the movable cylinder and connected with the air pump. The opening degree of the two forceps arms is accurately controlled through the front position and the rear position of the movable cylinder, dynamic change of the renal artery among the non-blocking state, the incomplete blocking state and the complete blocking state in the operation is achieved, the kidney operation can be completed in cooperation with a doctor, and the postoperative renal dysfunction risk of a patient can also be reduced.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular, it relates to an adjustable renal artery occlusion clamp pressure. Background technique [0002] Major renal artery occlusion clamp for clamping the renal artery surgery in the kidney, the renal artery to block blood supply to the kidneys, such that in a state of temporary renal ischemia, kidneys doctors to tumor resection, wound stitching and other related operations. However, artery occlusion may affect short-term or even long-term postoperative renal function, specific effect on the degree of artery occlusion time have a great relationship. In order to protect the patient's postoperative results as far as possible, the doctor will be based on intraoperative bleeding flexible control of renal artery occlusion clamp, the kidney is not entirely ischemic state, thereby reducing the chance of postoperative renal dysfunction occurs. Currently, physicians use renal artery occlusion cl...
