The minimally invasive implantation ring cutter is a medical instrument and is mainly used for cutting alveolar bones in clinical dental implantation operations at present, and cutting off part of the keratinized gingiva so that an operation area has the keratinized gingiva with enough width; the minimally invasive circular cutting can replace a large-area flap, and can reduce pain of a patient and accelerate healing time without suturing.
In dental implant surgery, a minimally invasive implant ring cutter may play an important role when it is necessary to cut an alveolar bone to an appropriate shape and size to accommodate an implant. The blades of the implant ring cutters are typically thin and sharp, and are capable of cutting bone tissue with minimal trauma and bleeding. It can be carefully cut around the alveolar bone to form a proper space before implant implantation. The minimally invasive implantation ring cutter is used for cutting the alveolar bone, so that the correct placement and stability of the implant are ensured, and the injury and discomfort to a patient in the operation process are reduced to the greatest extent. Such minimally invasive surgical methods generally provide faster healing and better implantation results. The existing planting ring cutters are all provided with cutting blades with annular structures, the structure is fixed and smaller, medical staff cannot adjust the size of a cut according to the cutting requirement of a patient, and the existing ring cutters are easy to scratch during installation of the medical staff without a protective structure; for this purpose, it is considered to provide a ring cutter which can adjust the size of the ring incision and has a safe scratch-proof structure. In view of this, we propose a minimally invasive planting ring cutter.
