Technical Field

The invention relates to the field of tooth implantation, in particular to a guide positioner of a key way type implant.

Background

Most of the existing planting positioners are fixing positioners for covering residual teeth or hard tissues, and the covering mucosa area is used for supporting. The direction and the depth of the special surgical drill point are limited through the central design hole. The position of the planting preparation hole is ensured not to be involved in destroying important anatomical structures, the operation safety is ensured, the postoperative reaction is relieved, and the later-stage repair is facilitated.

However, the implant positioner in the prior art can cover the residual teeth or hard tissues, and mucosa can prevent cooling water in the operation from flowing into the operation area, so that the drill bit is not heated in time to cause bone burn, and the implant area is not formed with bone to cause operation failure. Moreover, the planting positioner in the prior art needs to use a special guide positioner customizing tool to prepare the hole, but the special guide positioner customizing tool is inconsistent with a doctor common tool, so that the doctor is unfamiliar with the use of the tool, and the smooth operation time and flow are influenced. In addition, the central hole covering operation area is used for controlling the reaming position and the reaming direction of the drill point, so that the visual field of a doctor is limited, the doctor is difficult to judge whether the drilling position is accurate, the doctor can not blindly rely on the positioner to perform the operation, the direction position cannot be judged whether to be consistent with the design position, the deviation is difficult to judge in advance, errors are caused, the direction position is deviated, even the operation fails, and important nerves and anatomical structures can be seriously damaged, so that major medical accidents are caused. The current locator of planting, with the art district bone reaming to being less than the implant diameter after, will take down the locator and use the bare-handed messenger of surgical instrument to operate the district bone and be equipped with the hole to final diameter and bare-handed tapping back, finally bare-handed screw in implant accomplishes the implant and implants. Because of the unable whole operation of accomplishing of locator, the deviation can be formed to three step of bare-handed at last to influence the operation effect, cause the operation position inconsistent with planning in advance, the effect is unsatisfactory, can cause operation failure and medical malpractice seriously. In addition, the special locator reaming tool is influenced by the central hole position covering operation area, the length of the drill bit needs to be increased to compensate the height of the central hole, after the height is increased, the opening of the patient with smaller opening degree cannot accommodate the length of the drill bit, so that a series of problems of drill bit fracture and the like in the operation caused by incapability of performing the operation or forced drilling are caused, the drill bit fracture can cause the danger of drill bits remaining in bones, or the fractured drill bits are mistakenly swallowed, and medical accidents and disputes are caused.
