AI Technical Summary
Technical Problem
Existing dental implant wrenches suffer from poor stability, large deviations in directional control, and are difficult and inaccurate to adjust in both directions within the confined space of the oral cavity, making it difficult to achieve precise implantation.
Method used
A bent handle and sleeve structure was designed, combined with a forward and reverse switching mechanism, including a rotating buckle, a limiting tooth, a limiting groove and a spring. It is made of 304 stainless steel and machined by CNC to ensure high precision and reliability.
Benefits of technology
It improves the precision of axial control and the ease of operation, enables convenient forward and reverse switching and stable torque transmission, and enhances the accuracy and efficiency of surgery.

Abstract
The invention relates to a wrench for dental implantation, which belongs to the technical field of dental surgical instruments, and comprises a handle, a sleeve and a forward and reverse rotation switching mechanism connecting the handle and the sleeve, the handle is provided with a palm contact part and a finger contact part which are bent at a preset angle, so that the force application direction of a thumb is closer to the axial direction of an implant, and the control precision is improved; the forward and reverse rotation switching mechanism comprises a slidable and rotatable rotating buckle, a direction limiting latch, a direction limiting clamping groove on the sleeve and a spring, rapid switching of forward and reverse rotation driving of the sleeve can be realized through backward pulling, rotating and rebounding, a fixing marble is arranged in the sleeve to temporarily fix the planting nail, and an elastic ring with a track is arranged outside the sleeve to enhance holding skid resistance. The problems that an existing wrench is poor in operation stability, inaccurate in axial control and tedious in forward and reverse rotation switching in a narrow oral cavity are solved, and labor-saving, fine and reliable operation is achieved.
