Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a membrane nail implanter with variable incident angle. Background Art

[0002] Tooth loss caused by trauma, periodontal disease, etc. is becoming more and more common. Using implant dentures for oral restoration has become the preferred option with predictable results in the development of modern dentistry. According to statistics, 40% to 60% of implant patients have insufficient bone mass and need to increase bone mass through various bone augmentation techniques to create conditions for implant restoration.

[0003] In guided bone regeneration technology, various membranes and mesh materials are often used to provide a stable space for bone grafts. In order to maintain the membrane or mesh structure in a stable position, it is necessary to use membrane pins to fix it so that the bone formation space of the bone graft material can be fully guaranteed. At present, the fixing devices on the market are all linear. In actual surgical operations, due to the space limitations of the oral opening, lip and cheek muscles and tongue tissue, it is difficult for linear fixing devices to fix membrane pins on the lingual side of the maxillary and mandibular alveolar bones, the maxillary tuberosity area and the mandibular molar retromolar pad area, which limits the scope of application of guided bone regeneration technology in clinical practice.

[0004] The working end requires a small operating space, which is conducive to operating in a small space in the oral cavity. Using a percussion force to fix the membrane nail to the bone surface is prone to the risk of membrane nail displacement and slippage, which is not conducive to clinical operation. At present, due to the lack of a membrane nail implantation device with a large incident angle range (such as 60° to 120°) and changes within the large incident angle range, it is impossible to implant the membrane nail into a suitable position in the oral cavity when the working end is at an angle of 60° to 120° with the access path.
