本实施例提供的骨钻瞄准器的使用过程为：首先在患者的喙突上截取骨块，之后在骨块上开设第一安装孔；将螺钉穿设在第一安装孔内；之后握持握持部10，向后拉拔旋转部202以使止挡部位于弧形滑道102内，之后扭转旋转部202以使止挡柱40正对第三卡槽，释放旋转部202，在抵顶弹簧50的作用下使止挡柱40滑设在第三卡槽内；之后将导向管穿入到患者的肩部组织内，向后拉拔旋转部202以使止挡柱40位于弧形滑道102内，之后扭转旋转部202以使止挡柱40正对第一卡槽，释放旋转部202以使止挡柱40滑设在第一卡槽内(以上步骤是针对在左侧肩胛骨上开设第二安装孔的情况，若在右侧肩胛骨上开设第二安装孔，需使止挡柱40滑设在第二卡槽内)；再将第二限位部301抵顶在肩胛骨的第二位置上，之后扭转握持部10，以使第一限位部201抵顶在肩胛骨的第一位置上，此时第一套管20和第二套管30的轴线正对肩胛骨上的预设位置；之后将骨钻穿设在第二套管30内，通过骨钻在肩胛骨上的预设位置开设第二安装孔；之后再向后拉拔旋转部202，以使止挡柱40位于弧形滑道102内，旋转旋转部202以使止挡柱40位于第三卡槽内，之后取出第一套管20和第二套管30；最后将骨块以及螺钉下放到患者肩部的组织内，并且将螺钉旋入到第二安装孔内，直至骨块贴附在肩胛骨上。The use process of the bone drill sight provided in this embodiment is as follows: firstly, a bone fragment is cut from the coracoid process of a patient, and then a first installation hole is opened on the bone fragment; the screw is inserted into the first installation hole; Holding the part 10, pull the rotating part 202 backwards so that the stopper is located in the arc-shaped slideway 102, then twist the rotating part 202 to make the stopper 40 face the third slot, release the rotating part 202, Under the action of the top spring 50, the stopper post 40 is slid into the third slot; then the guide tube is inserted into the shoulder tissue of the patient, and the rotating part 202 is pulled backward to make the stopper post 40 in the arc shape Inside the slideway 102, then twist the rotating part 202 to make the stop column 40 face the first slot, release the rotating part 202 to make the stop column 40 slide in the first slot (the above steps are for the left scapula In the case of opening a second installation hole on the upper side, if a second installation hole is opened on the right scapula, the stopper column 40 needs to be slid in the second slot); In the second position, then twist the grip portion 10 so that the first limiting portion 201 abuts against the first position of the scapula, and the axes of the first sleeve 20 and the second sleeve 30 are facing the scapula. preset position; then put the bone drill through the
具体地，第二限位部301的前端设置有凸出部3011。凸出部3011可以增大第二限位部301与肩胛骨之间的摩擦力，以免在操作的过程中第二限位部301在肩胛骨上滑动。Specifically, the front end of the second limiting
具体地，凸出部3011为多个，多个凸出部3011间隔的设置在第二限位部301的前端。以进一步增大第二限位部301与肩胛骨之间的摩擦力。Specifically, there are multiple protruding
