Tool bit service life testing device of ultrasonic knife

Abstract

The invention discloses a tool bit service life testing device of an ultrasonic knife, and belongs to the technical field of ultrasonic knives. The device comprises a test platform, a knife body positioning assembly is arranged on one side of the upper end of the test platform, and a bearing simulation assembly is arranged on the other side of the upper end of the test platform. A trigger action assembly is arranged on one side, close to the knife body positioning assembly, of the middle of the upper end of the test platform. According to the device, a driving motor rotates to drive a sector gear to rotate, the sector gear is engaged with a rack to enable a sliding seat to slide along a sliding rail, and a trigger piece is driven to press an ultrasonic knife trigger. Due to the structuralcharacteristics of the sector gear and the rack, the sliding seat reciprocates along the sliding rail, and the reciprocating motion is stable. The stepping motor works to drive the lead screw to rotate, the connecting sliding base on the surface of the lead screw slides along the sliding frame to drive the adjusting rolling wheel to ascend and descend, the adjusting rolling wheel adjusts the height of the bearing belt bearing the simulation assembly, adjustment is stable, and precision is high.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knife, and in particular relates to a tool head life testing device of an ultrasonic knife. Background technique [0002] Ultrasound generally refers to high-intensity focused ultrasound therapy. High-intensity focused ultrasound therapy is a new type of tumor treatment. When using this method to treat tumors, ultrasonic positioning can be used, high-intensity ultrasonic waves can be used to kill tumor cells in the target area without damaging the surrounding normal tissues, and the thermal effect of ultrasonic waves at the focus can form a high temperature above 60°C in the target area, resulting in protein Degeneration and coagulation necrosis of tissue cells or irreversible severe damage, so as to achieve the purpose of treating tumors. [0003] The prior art has the following problems: the existing ultrasonic knife head life testing device drives the trigger part to reciprocate through th...
