Description

Technical Field

[0001] This utility model relates to the field of medical clamping technology, and in particular to a self-locking guide clamp for installing zirconia ceramic blocks. Background Technology

[0002] In the field of precision ceramics manufacturing, zirconia blocks are widely used in dental prostheses, joint replacements, and other medical implants due to their excellent mechanical properties and biocompatibility. The installation process of these materials faces three major technical barriers: First, the inherent high brittleness of zirconia (HV1200-1400) makes traditional clamping methods prone to edge chipping and microcracks; second, the stringent geometric accuracy requirements of medical components (such as crown margin gaps ≤50μm) necessitate sub-millimeter-level positioning control; and third, the dynamic loads in multi-axis machining require clamps with vibration-resistant loosening characteristics.

[0003] Existing application number CN201520016335.2 discloses a medical clamp, including a clamp base 1 with a through hole 2 at its center. A handle body is provided above the clamp base 1. The handle body consists of four parts: a housing 3 fixedly welded above the clamp base 1, a handle 4 located on the housing 3, a linear motor 5 fixedly installed inside the housing 1, and a push rod 6 with one end fixedly connected to the telescopic end of the linear motor 5 and the other end passing through the through hole 2. Three bent clamping rods 7 are hinged to the bottom edge of the clamp base 1. A triangular sliding block 8 is fitted onto the upper part of the three bent clamping rods 7. The other end of the push rod 6 is fixedly welded to the center of the sliding block 8. The bottom of each of the three bent clamping rods 7 is provided with a clamping piece 9. However, the existing technology is not very adaptable to different drugs that need to be clamped and the size and shape of zirconia ceramic blocks during use. It is difficult to achieve accurate positioning and stable clamping. Moreover, medical supplies have extremely high hygiene requirements, and the existing clamps cannot meet the aseptic operation standards, which leads to the risk of cross-infection during use and affects the treatment effect.
