The invention discloses a mechanical tensioning device, which comprises drag hooks; the mechanical tensioning device is characterized by further comprising a movable frame, wherein the movable frame comprises a transverse rod and two vertical rods; the two vertical rods are fixedly connected to two ends of the transverse rod; a first sliding block and a second sliding block are connected to the transverse rod in a sliding mode; locking mechanisms between fixed pulleys and the transverse rod are arranged on both the first sliding block and the second sliding block; second fixed pulleys are arranged on the two vertical rods; pull ropes are arranged on the first and second fixed pulleys; each drag hook is fixedly connected to one end of the corresponding pull rope; pull tapes are connected tothe other ends of the pull ropes; ratchet bars are arranged on the pull tapes; and clamping mechanisms, which are matched with the pull tapes, are arranged on the vertical rod. With the application of the mechanical tensioning device provided by the invention, problems in the prior art that surgical operations are inconvenience and injuries are caused to the sternum of a patient since the position of drag hooks cannot be adjusted and tension force for tensioning the sternum cannot be adjusted.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a mechanical tensioning device. Background technique [0002] When the hospital performs thoracic surgery (such as lung resection), in order to open the patient's chest, it is generally necessary to saw off the patient's sternum first, and then set several retractors on the left and right sides of the sternum to tighten the sternum through the retractors. In this way, the opening of the patient's chest is enlarged, which facilitates the operation. However, in the process of tightening the sternum, the existing retractors are generally fixed, and their positions cannot be adjusted. Also can't adjust, so just bring a lot of inconvenience to operation, not only influence doctor's operation operation, also may cause injury to patient's sternum. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a mechanical tensioning d...
