Abstract

The invention relates to the field of medical instruments, and discloses a draw hook mechanism and a cesarean delivery abdomen draw hook device. The draw hook mechanism comprises a frame, wherein a connecting piece is movably arranged on the frame, a through hole is formed in the end of the connecting piece, and a first rotating shaft is rotatably arranged in the through hole; two ends of the first rotating shaft extend out of the through hole and are connected with drag hooks through connecting rods, a first gear is coaxially fixed to the end of the first rotating shaft, a second rotating shaft is rotatably arranged at one end close to the drag hooks, of the connecting piece, and a second gear meshed with the first gear is coaxially fixed to one end of the second rotating shaft; and the cesarean delivery abdomen draw hook device comprises the draw hook mechanism and further comprises a frame body, an annular rail is arranged on the frame body, and the draw hook mechanism is arranged on the annular rail. The draw hook mechanism solves the problems that in the prior art, the length and the bending degree of the draw hook body are inconvenient to adjust, and the position of the drawhook body on a supporting frame body is inconvenient to adjust and fasten.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a retractor mechanism and a cesarean abdomen retractor device. Background technique [0002] When performing cesarean section, it is often necessary to use multiple retractors to open the incision for surgery. If only relying on assistants for retractor assistance, not only the operation is very cumbersome, but also time-consuming and laborious, delaying the treatment time; The device that can fix the retractor saves manpower and facilitates the operation. For example, the Chinese patent with the patent number CN201920139450.7 provides a retractor for hepatobiliary tumor surgery, including a retractor body, the outer wall of the retractor body is connected with a through hole, and The connecting through holes are set on the first supporting frame and the second supporting frame. The surgical pull hook for liver and gallbladder tumor surgery is provided with a connecting groove ...
