Abstract

The invention discloses a retraction system for surgery. The retraction system includes bodies, handles, connecting rods, pivot assemblies, claw hooks and expanding rods; a body A is in hinged joint with a body B; the inner ring at the articulated joint of the body A is provided with a threaded hole, and the outer ring of the articulated joint of the body B is provided with a circular groove; a wing bolt is in threaded connection with the threaded hole in the body A after passing through the circular groove in the body B; bosses are arranged on the right ends of the body A and B; the two handles are sleeved on the bosses of the body A and B and fixed by using spring locking pieces; the positions that the bosses on the body A and B cooperate with the spring locking pieces are provided with grooves; the bodies are in hinged joint with the connecting rods; the connecting rods are in pivoted joint with the pivot assemblies; the pivot assemblies are fixedly connected to the expanding rods; and the claw hooks are detachably connected to the connecting rods. Through the retraction system, the claw hooks can move on retraction rods; the space, quantities and specifications of the claw hooks are selectable; and as the claw hooks are level with the skin, surgery field and instrument operation can not be impeded.

Description

technical field [0001] The invention relates to the field of medical equipment and supplies, in particular to a surgical retraction system. Background technique [0002] Existing keyhole minimally invasive surgery requires a small incision in the skin, and minimally invasive operation after retraction. The existing retractors are all fixed retractors, and the claws cannot adjust the length and distance. Hooks often obstruct the surgical field. Contents of the invention [0003] The object of the present invention is to provide a retraction system for surgical operation aiming at the deficiencies in the prior art. [0004] To achieve the above object, the present invention takes the following scheme: [0005] A retraction system for surgery, including a body, a handle, a connecting rod, a pivot assembly, a claw hook, and an extension rod. It is characterized in that body A and body B are hinged as one, and the inner circle of the hinge point of body A is provided with thr...
