Abstract

The invention discloses a bone drilling device for the orthopedic surgery based on vibration drilling. The bone drilling device comprises a bottom plate, a linear guide rail, a sliding block, an upper plate, a piezoelectricity actuator, a coupler, a direct current motor, a motor installing base and a drive control mechanism. The linear guide rail is fixed on the bottom plate. The sliding block is connected with the linear guide rail in a sliding mode. A vertical plate is arranged on the tail of the upper plate. The tail of the piezoelectricity actuator is fixed on the vertical plate of the upper plate. The output end of the piezoelectricity actuator is connected with the direct current motor through the coupler. The direct current motor is fixed on the front portion of the upper plate through a motor installing base. The drive control mechanism drives the piezoelectricity actuator and the direct current motor to work. The vibration drilling technology is applied to the bone drilling device for the orthopedic surgery, heat produced by the friction between a cutter and a workpiece in the process of cutting, the heat produced by the fracture and deformation of the workpiece due to cutting can be effectively reduced, and the drilling precision is effectively improved due to the rigidity effect, caused by vibration drilling, of a drill bit.

Description

technical field [0001] The invention relates to a bone drilling device for orthopedic surgery based on vibration drilling. Background technique [0002] With the continuous promotion and deepening of the minimally invasive concept in orthopedic surgery, it has become an important direction for the future development of orthopedic surgery to minimize the damage to patients caused by surgical operations on the premise of ensuring the surgical effect. As one of the most basic and common surgical operations in orthopedic surgery, the cutting heat generated during drilling can cause irreversible damage to bones. Thermal injury can lead to bone gangrene and even osteomyelitis, which will not only affect postoperative recovery but also directly affect the effect of surgery. [0003] Vibration drilling is a new drilling method that adds axial high-frequency vibration to the drill bit. The pulse action brought by the additional vibration can effectively improve the drilling effect ...
