Incision opening device for minimally invasive surgery

Abstract

The invention discloses an incision distraction device for minimally invasive surgery, and belongs to the technical field of minimally invasive surgery, the incision distraction device comprises a C-shaped distraction ring, the surface of the C-shaped distraction ring is slidably connected with a positioning mechanism, the surface of the positioning mechanism is fixedly connected with a wound retraction adjusting device, the inner end of the wound retraction adjusting device is fixedly connected with a wound retraction device, and the wound retraction device is fixedly connected with a wound retractor. The fixing block is arranged above the C-shaped opening ring, the limiting block is slidably connected to the inner wall of the fixing block, the pull rod is fixedly connected to the upper surface of the limiting block, and the sliding groove is formed in the side wall of the limiting block. A fixing block is arranged on the upper surface of a sliding block sliding on the surface of the C-shaped distraction ring, a limiting block is connected with a pull rod and slidably ascends and descends in the fixing block, a limiting gear is clamped in a limiting groove formed in the lower surface of the limiting block, and the limiting gear is connected with a positioning gear meshed in a gear groove formed in the surface of the C-shaped distraction ring through a linkage rod. And the fixed block can be conveniently controlled to be fixed and slide on the surface of the C-shaped distraction ring.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgery, in particular to an incision opening device for minimally invasive surgery. Background technique [0002] Minimally invasive surgery, as the name suggests, is surgery with minimal trauma. It refers to the use of laparoscopes, thoracoscopes and other modern medical equipment and related equipment for surgery. Early minimally invasive surgery refers to a new technology for performing surgery in the human body through laparoscopes, thoracoscopes and other endoscopes. Minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. [0003] When performing minimally invasive surgery, it is necessary to use a retractor to retract the tissue, revealing the scope of operation, which is convenient for exploration and operation. During the operation, the doctor sometimes needs to move his position to better perform the operation, but the existing When the ...

Problems solved by technology

[0003] When performing minimally invasive surgery, it is necessary to use a retractor to retract the tissue to reveal the scope of the operation, which is convenient for exploration and operation, and the doctor sometimes needs to move his position during the operation to better perform the operation, but the existing When the retractor is in use, because the retractor device is too large, and the retractor cannot be moved after the incision is stretched, it is very easy to affect the doctor's operation. Therefore, we propose an incision distraction device for minimally invasive surgery
