Abdomen opening device

Abstract

The invention discloses an abdomen opening device, which comprises two abdomen opening arms one ends of which are hinged together, and the other ends are respectively provided with an abdomen opening plate, the hinged end of the two abdomen opening arms is provided with a locking device, at least one abdomen opening arm is in sliding connection with a pull rod, the abdomen opening arm is also provided with a pull rod locking device, and the end close to the abdomen opening plate on the pull rod is provided with a viscus dragging plate; and the viscus dragging plate is connected on the pull rod via a direction regulating mechanism. When abdominal surgery is carried out, the abdomen opening device can make the operative field exposed sufficiently, the viscera dragging plate at the pull rod stretch-in end is used for poking other viscera to replace the manual operation of medical workers, which is conductive to controlling the force and the angle when dragging the viscera, and greatly reduces the working intensity of the medical workers, so the invention has the advantages of ensuring the angle and the force for dragging the viscera and ensuring the exposure of the operative field.

Description

technical field [0001] The invention belongs to the field of instruments for abdominal surgery, in particular to an opener 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 laparotomy from the incision to stretch the abdominal wall and expose the operative field. The existing abdominal opener comprises two abdominal arms hinged together at one end, each of the bottoms of the two abdominal arms is provided with a web plate, and the abdominal arm is opened during use so that the two abdominal arms form a certain angle, and the web plate resists The abdominal wall, thus exposing the operative field. The disadvantage of this laparotomer is that 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. The angle and streng...

Problems solved by technology

The disadvantage of this laparotomer is that 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. The angle and strength of the instrument will easily cause unstable exposure of the surgical field, increase the labor intensity of the medical staff, and easily prolong the operation time, which is not conducive to the recovery of the patient.
