Abstract

The invention relates to a medical device, and discloses a Chester sternal retractor, which comprises two upright bars and an upper fixed cross bar, the two ends of the upper fixed bar are respectively connected with the two upright bars through pull hook fixers, and the two upright bars The rod ports are equipped with nut limit blocks, and the other ends of the two vertical rods are equipped with a vertical rod holder; the two vertical rods and the upper fixed horizontal rod are respectively equipped with a movable left hook, a movable right hook and a movable hook through the hook holder. The movable left retractor, the movable right retractor and the movable upper retractor can be respectively fixed at the middle position on the rod, and their extension lengths can also be adjusted and fixed according to the physical needs of the patient during the operation. The present invention is reasonable in structure, fast in installation, and the three-dimensional pulling hook composed of the upper side, the left side, and the right side can broaden the intraoperative field of view, meet the requirements of thoracic surgery, and make the operation convenient and unimpeded.

Description

technical field [0001] The invention relates to a medical device, in particular to a Chester sternal retractor. Background technique [0002] For tumors behind the sternum, the main traditional surgical method is sternal splitting, that is, splitting the sternum from top to bottom with an electric saw, and then forcibly pulling and fixing it with a steel wire after the operation.
