Problems solved by technology

The traditional drill end does not have the function of adjusting the direction and length. When the operating space is narrow or corner operation is performed, there will be a dead angle, and the drill cannot reach the corresponding position.
In addition, when using drilling methods, medical staff often need to manually apply pressure to push the drill bit forward. However, the thrust is often uneven, the direction is unstable, and it is difficult to accurately grasp it, resulting in a large error in the size of the drilled hole.

Abstract

The invention discloses a medical universal drill, which comprises a drill bit, a rod body and a handle, wherein the drill bit includes a drill bit and a long rod, and can be a grinding drill bit and a drilling drill bit, which respectively realize grinding and drilling functions. It also includes a telescopic assembly for adjusting the axial position of the drill bit. The telescopic assembly includes a pull sleeve and a lock nut, wherein the pull sleeve includes an open pipe, a threaded rod fixedly connected to one end of the open pipe, and a threaded rod arranged on the The frustum on the outside of the open pipe, the open pipe and the frustum are axially provided with a gap, and the lock nut is threadedly matched with the threaded rod; in addition, it also includes an impact assembly, which is used to apply an axial force to the drill bit. impact force; steering assembly for adjusting the angle of the drill bit. The angle and length of the drill bit of the invention can be adjusted, so that there is no operation dead angle in the narrow operation field, the pressure is stable and uniform, the drilling error is reduced, the operation is convenient and flexible, the use effect is good, and it can be popularized and applied.

Description

technical field [0001] The invention relates to a medical universal drill, in particular to a medical percussion drill capable of adjusting the angle and length, and belongs to the technical field of medical instruments. Background technique [0002] During surgical treatment of diseases, sometimes it is necessary to drill for bone grinding or use a perforator to drill holes. The traditional drill end does not have the function of adjusting the direction and length. When the operating space is narrow or corner operation is performed, there will be a dead angle, and the drill cannot reach the corresponding position. In addition, when drilling, medical staff often need to manually apply pressure to push the drill forward. However, the thrust is often uneven and the direction is unstable, making it difficult to accurately grasp, resulting in large errors in the size of the drill. With the popularization of precise minimally invasive surgery, in order to improve the efficiency ...
