Description

Film nail holder

Technical Field

The utility model relates to a membrane nail holder.

Background

In implant surgery, GBR (guided bone regeneration) and sausage techniques are often used to expand bone volume, allowing smooth treatment of the thin site implant. In this case, membrane nails are required for laying and fixing the barrier membrane. Because the membrane nails are relatively thin, the nail holder is required to be used for taking, positioning and knocking the nail from the nail box to the position where the nail needs to be knocked. However, due to the bone mass of different patients, the more relaxed cortical bone can lead to the phenomenon that the knocked-in membrane nail is carried out together during the removal of the nail holder.

The existing solution is that a sharp blade needs to be re-inserted into an operation area, a membrane nail is knocked into the bone surface under the periosteum, a back of a scalpel is used for being inserted into a gap of the head of a nail holder, a membrane nail cap is pressed, and then the nail holder is pulled out. However, if the patient moves, the membrane is extremely easy to be damaged or accidentally damaged. In addition, because of fear of the removal of the nailed head, the operator often uses force to drive the membrane nail into the bone surface, and because the nail holder surrounds the membrane nail cap, the membrane surface is sometimes pierced, resulting in "perforation" of the membrane, and the membrane is directly removed from the integrity of the membrane, resulting in failure of the fixation of the membrane.

In addition, because the diameters of the film nail caps of different systems are different, the film nails of the same system need to use matched nail holders, so when one film nail is broken, after the film nails of other brands are replaced, the nail holders of other brands need to be replaced, and the material waste is caused.
