Medical universal drill

Abstract

The invention discloses a medical universal drill. The drill comprises a drill bit, a rod body and a handle, wherein the drill bit comprises a drilling tool and a long rod, and can be an abrasive drill bit and a drilling bit for respectively achieving grinding and drilling functions. The drill further comprises a telescopic assembly used for adjusting the axial position of the drill bit, wherein the telescopic assembly comprises a pull sleeve and a locking nut, the pull sleeve comprises an open pipe, a threaded rod fixedly connected to one end of the open pipe and a frustum arranged on the outer side of the open pipe, gaps are formed in the open pipe and the frustum in the axial direction, and the locking nut is in threaded fit with the threaded rod; and in addition, the drill further comprises an impact assembly used for applying axial impact force to the drill bit; and the drill further comprises a steering assembly used for adjusting the angle of the drill bit. The angle and the length of the drill bit can be adjusted, so that no operation dead angle exists in a narrow operation field, pressure application is stable and uniform, drilling errors are reduced, operation is convenient and flexible, the using effect is good, and popularization and application can be achieved.

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 ...

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.
