The front end of the bone drill shell 1 is sleeved with a guiding and positioning piece 6 which is coaxial with the positioning and clamping mechanism 5 and guides and centers the Kirschner wire 4. Because the positioning and clamping mechanism 5 is clamped at the end part of the Kirschner wire 4, the Kirschner wire 4 receives resistance during drilling and can generate certain bending deformation. Therefore, the guiding and positioning piece 6 arranged at the front end of the bone drill shell 1 can correct, guide and center the Kirschner wire 4, and ensure that the Kirschner wire 4 is fed along the axis. The driving mechanism 2 drives the transmission mechanism 3 to drive the positioning and clamping mechanism 5 to rotate and move along the axial direction of the bone drill shell 1, so that the drilling process is completed at one time, and the function of continuous needle insertion is realized.
In this embodiment, the transmission mechanism 3 includes a planetary gear set 31, a support pillar 32 and a rack 33, the support pillar 32 is fixedly mounted on the bone drill housing 1, the planetary gear set 31 is connected with the driving mechanism 2 and is slidably mounted on the support pillar 32, and the rack 33 is fixedly mounted on the bone drill housing 1 and is engaged with the planetary gear set 31.
