Thebarrel 5 is firmly fixed in a certain position; after that, thedrill bit 6 passes through theprotective sleeve 5 to make a hole, and smoothly passes through the locking nail hole on theintramedullary nail 1 .

由于远端瞄准模块4与近端瞄准模块3之间为可拆卸连接，使用中，可先进行近端瞄准操作，之后再在近端瞄准模块3上安装上远端瞄准模块4进行远端瞄准操作，这样髓内钉锁定机构能够同时实现近端瞄准和远端瞄准，且由于手术器械一般质量比较大，可先不安装远端瞄准模块4，能够方便操作者的操作。相对于近端瞄准与远端瞄准分体式锁定机构，其能够省去操作者在手术中更换手术器械的步骤，进而节约手术时间和手术成本，具有较好的经济性和实用性；且所述髓内钉锁定机构结构简单，使用方便；Since the distal aimingmodule 4 and the proximal aimingmodule 3 are detachably connected, in use, the proximal aiming operation can be performed first, and then the distal aimingmodule 4 can be installed on the proximal aimingmodule 3 for distal aiming. In this way, the intramedullary nail locking mechanism can simultaneously achieve both proximal and distal targeting, and since surgical instruments are generally of relatively large mass, thedistal targeting module 4 may not be installed first, which is convenient for the operator to operate. Compared with the split locking mechanism for the proximal end aiming and the distal end aiming, it can save the operator's steps of changing surgical instruments during the operation, thereby saving the operation time and operation cost, and has better economy and practicability; The intramedullary nail locking mechanism has a simple structure and is easy to use;

另外，所述髓内钉锁定机构由于设置近端阻尼片322及远端阻尼片422，能够防止手术中导向套筒的晃动，保证定位准确；且所述髓内钉锁定机构的近端瞄准臂321和远端瞄准臂421的可拆卸连接结构固定方式稳固，也能够防止手术中手术器械的晃动；In addition, the intramedullary nail locking mechanism is provided with the proximal dampingsheet 322 and the distal dampingsheet 422, which can prevent the guide sleeve from shaking during the operation and ensure accurate positioning; and the proximal aiming arm of the intramedullary nail locking mechanism The detachable connection structure of 321 and the distal aimingarm 421 is fixed in a stable manner, and can also prevent the shaking of surgical instruments during surgery;

另外，所述髓内钉锁定机构由于能够调节髓内钉1的旋转角度以及上下位置，可满足不同身高人群、不同骨结构弯曲人群等各种需求。In addition, since the intramedullary nail locking mechanism can adjust the rotation angle and the upper and lower positions of theintramedullary nail 1 , it can meet various needs of people with different heights, people with different bone structures, and the like.
