AI Technical Summary

Technical Problem

The marking nail clamping device of existing surgical navigation robots can easily cause the marking nail to tilt when it contacts and disengages the marking nail, and the elasticity of the spring or torsion spring becomes weak after long-term use, affecting the clamping effect.

Method used

A convenient nail holding device is designed, including a central rod, a cross-hinged clamping handle and a sleeve. The rotation of the clamping handle depends on the coordination of the driving rod and the guide groove, and the opening and closing of the clamping handle is driven by the sliding of the sleeve.

Benefits of technology

When contacting or releasing the marking nail, the two clamping handles operate almost simultaneously, avoiding the marking nail tilt, and achieving a firmer clamping through the coordination of the drive rod and the guide groove, without considering the elastic loss of the elastic element, and a longer service life.

Abstract

The utility model relates to the technical field of medical instruments, in particular to a convenient nail holding device which comprises a center rod. The two clamping handles are hinged to the front end of the center rod in a crossed mode; guide grooves are formed in the ends, close to the rear end of the center rod, of the clamping handles; the end, close to the front end of the center rod, of the clamping handle is used for clamping a mark nail. The sleeve is arranged on the center rod in a sliding and sleeving mode, a driving rod is arranged on the sleeve and is in sliding fit with the guide groove, and the guide groove is bent in the extending direction of the clamping handles so that the sleeve can drive the two clamping handles to be opened and closed when sliding relative to the center rod. According to the portable nail holding device provided by the invention, when the marking nail is contacted or loosened, the two clamping handles almost simultaneously contact or loosen the marking nail, so that the problem of inclination of the marking nail caused by single-side clamping is avoided; in addition, the nail holding device can clamp the marking nail more firmly, and meanwhile due to the fact that the elastic loss of the elastic element does not need to be considered, the service life of the nail holding device can be longer.
