The invention belongs to the technical field of medical apparatus, in particular to a breastbone opening device for clinical application in thoracic surgery. The breastbone opening device comprises aregulating mechanism, wherein arc supporting rods are mounted at two ends of the regulating mechanism; a clamping groove is formed in the free end of each arc supporting rod; the regulating mechanismcomprises a mounting frame and two mounting blocks; a supporting rod is fixedly arranged on each mounting block; a rack is fixedly mounted on each supporting rod; a rotating shaft is rotatably mountedon the mounting frame; a gear and a worm gear are fixedly mounted on the rotating shaft; the gear is meshed with the two racks; a worm is also rotatably mounted on the mounting frame, and is meshed with the worm gear; a sliding groove is also formed in each supporting rod; and a sliding block is mounted in each sliding groove in a sliding manner, and is detachably mounted on the mounting frame. The invention aims to solve the problems that in the conventional breastbone opening manner, the breastbone is not supported, the opening state of the breastbone cannot be effectively maintained, the fixing difficulty is high, and slipping is easy to generate.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a sternal spreader used in thoracic surgery. Background technique [0002] Sternal distractor is a tool commonly used in thoracic surgery. Its function is to stretch the sternum to a certain extent to facilitate the establishment of surgical access. The traditional sternal distractor has a relatively simple structure and is similar in shape to a The vernier caliper is composed of a fixed arm and a movable arm and a slideway, wherein the movable arm and the fixed arm are used to spread the ribs. [0003] In thoracic surgery, it is necessary to use a sternum spreader to open the sternum, and then operate on the internal organs. During the operation, the adjustment steps of the sternum spreader are cumbersome, difficult to fix, easy to fall off, and often cannot effectively maintain the open state of the sternum. Contents of the invention [0004] The purpose ...
