Synchronous retraction device for bilateral muscles of wound

Abstract

The invention relates to the field of general surgery operation auxiliary equipment, in particular to a synchronous retraction device for bilateral muscles of a wound. The synchronous retraction device for the bilateral muscles of the wound comprises a bottom plate, two bases slidably arranged on the bottom plate, traction ropes slidably wound on the two bases, two retraction hooks respectively arranged at two ends of the traction ropes and a driving mechanism used for driving the two bases to synchronously move in approach or apart directions; one sides of the two bases, far away from each other, are provided with a plurality of fixed pulleys for winding the traction ropes at intervals in the height direction, and the traction ropes are wound on the fixed pulleys of the two bases in an inverted C shape; the driving mechanism comprises a lead screw and nuts, wherein the lead screw is rotatably arranged in a strip-shaped chute, the nuts matched with the lead screw are respectively arranged on the two bases, and the rotation directions of two sections of threads which are respectively matched with the two nuts on the lead screw are opposite to each other. According to the synchronousretraction device for the bilateral muscles of the wound, retraction of the bilateral muscle tissue of the wound can be quickly carried out, and meanwhile, over-compression of unilateral muscle tissue caused by the movement of operation part in the retraction process or in the operation can be avoided.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for general surgery, in particular to a device for synchronous retraction of muscles on both sides of a wound. Background technique [0002] In general surgery, some operations need to retract the skin, muscle or tissue of the surgical site to fully expose the surgical field of view and facilitate accurate surgery. A kind of retraction method in the prior art is that the muscles on both sides of the surgical wound are reversely stretched by the assistant through the retractable hook and the traction rope. This method is likely to cause the wound site to shake due to hand shaking during the operation, making the surgical field of view The exposure changes randomly, and there is a risk that the wound will be closed due to hand slipping, which will affect the continuous operation of the operation; another retraction method uses a retractor, such as a muscle retraction device for general surgery in ...

AI Technical Summary

Problems solved by technology

Since the supporting frames such as the retractor ring of this type of retractor are all set in the surgical incision, a larger incision is required, and the intraoperative field of view at the incision position of the skin, muscle or tissue is affected, which is not conducive to postoperative recovery. Muscle tissue bleeding can not be detected and treated in time

[0003] Though CN106037842B discloses a kind of muscle retraction device for general surgery that makes up for the deficiencies in the above-mentioned prior art, there are still the following problems in clinical use: 1. The muscle tissues on both sides of the incision have different positions due to their different positions. Elasticity and tension, when adjusting the sliding of the two columns through the rotating disc to retract the muscle tissue on both sides of the incision, it is impossible to ensure that the muscle tissue on both sides is evenly stressed, often causing the muscle tissue on one side to be over-extruded, and the muscle tissue Necrosis occurs, which increases the pain of the patient and is not conducive to postoperative recovery; 2. Although there is a fixation device for clamping the surgical site, because the positions of the two retraction hooks are fixed, and the operation process cannot be avoided due to the patient's own or The rotation or displacement of the surgical site caused by medical staff, and once the surgical site moves, will inevitably cause further excessive extrusion of unilateral muscle tissue, which will also increase the pain of the patient and is not conducive to postoperative recovery; 3. The two retraction hooks need to pass through the corresponding The rotary disc operation moves, and the retraction speed is slow
