Abdominal cavity distraction device

Abstract

The invention discloses an abdominal cavity distraction device which comprises a support connected to a bed body. A sleeve is arranged on the support. Two abdomen distraction arms which are driven by a driving mechanism to move relatively are connected in the sleeve in a sliding mode. Abdomen distraction plates are arranged at the outer-extending ends of the two abdomen distraction arms respectively. Inserting long grooves are formed in the two abdomen distraction arms respectively. Pulling rods with the widths smaller than those of the inserting long grooves are inserted in the inserting long grooves. Viscera traction plates are arranged on the end portions, extending to the positions between the two abdomen distraction arms, of the pulling rods. The abdomen distraction arms are connected with locking bolts which extend into the inserting long grooves in a screwing mode. The abdominal cavity distraction device has the advantages that the angle and the force of viscera traction can be guaranteed, and surgical field exposure can be guaranteed.

Description

technical field [0001] The invention belongs to the field of instruments for abdominal surgery, in particular to an abdominal spacer for opening the abdominal cavity. Background technique [0002] When performing abdominal surgery, it is necessary to make an incision from the abdominal wall, and extend the abdominal spacer from the incision to open the abdominal wall to expose the operative field. The existing abdominal space expander comprises two abdominal arms hinged together at one end, each of the bottoms of the two abdominal arms is provided with a web plate, the abdominal arm is opened during use so that the two abdominal arms form a certain angle, and the web plate resists Hold the abdominal wall, thereby exposing the operative field. The disadvantages of the abdominal spacer are: there are many viscera in the abdominal cavity. When performing an operation on a certain viscera, many medical staff need to use medical instruments to pull other viscera from all directi...

AI Technical Summary

Problems solved by technology

The disadvantages of the abdominal spacer are: there are many viscera in the abdominal cavity. When performing an operation on a certain viscera, many medical staff need to use medical instruments to pull other viscera from all directions, and it is difficult for the medical staff to ensure the pulling The angle and strength of the organs can easily lead to unstable exposure of the surgical field, increase the labor intensity of medical staff, and easily prolong the operation time, which is not conducive to the recovery of patients
