Medical appliance for dental implant
Technical Field
the invention relates to the technical field of medical instruments, in particular to a medical instrument for dental implantation.
background
Dental implants, which are one of the ideal methods for repairing missing teeth at present, are considered as one of the most important advances in oral medicine in the 21 st century, and one of the most critical steps of dental implants is to incise the gum of the missing tooth site and retract it so as to implant an implant (artificial tooth root) into the alveolar bone. However, since the space in the oral cavity is narrow and general surgical retractor or retractor cannot be used, at present, the retractor can only be replaced by some small instruments (such as periosteum stripper, etc.) to retract the gingiva, and some people pull the gingiva by suturing on the gingiva, which not only affects the surgical operation, but also easily damages the gingiva, so that it is very necessary to develop a special medical instrument for dental implant.
chinese patent CN203183059U discloses a gum retractor special for tooth implantation, which comprises a retractor arm, a gum retractor, support rods, a stretching screw, a driving nut and a retention clamp, wherein when in use, the driving nut is rotated to retract the stretching screw, so that the two support rods are pulled to be upright, the support retractor arm is extended and drives the gum retractor to move outwards, the gum is pulled to both sides, and then the retractor is fixed by the retention clamp. However, the structure of the device is simple, according to the lever principle, the gum can be retracted by using a large force, the working strength of medical staff is increased, meanwhile, the positioning needs to be accurate, the medical staff needs to spend a long time when positioning, and obviously, one hand is not feasible when the nut is driven to rotate, the pulling arm needs to be held by one hand, and the nut is driven to rotate by the other hand. Therefore, a new technical solution is needed to solve the above technical problems.
