Directional scanning device and method for acquiring real-time position in implant drill needle operation

Abstract

The invention discloses a directional scanning device for acquiring a real-time position in an implant drill needle operation. The directional scanning device comprises a sleeve, wherein a vertical blind hole is formed in the center of the bottom of the sleeve; the aperture of the blind hole is matched with a drill needle; a visible window penetrating through the side wall of the sleeve is formed in one side of the top of the blind hole; and a pointing structure consisting of two cross-shaped pointers is arranged at the top of the sleeve. The directional scanning device disclosed by the invention is matched with a mouth scanning system, the position and angle of the drill needle in the implant operation are checked in real time, the three-dimensional position of an intra-osseous cavity is deduced by combining the pointing direction of the scanning device, and the three-dimensional position is compared with the preoperative design for correction, so that the precision of implant cavity preparation in the implant operation process is further improved, and smooth implementation of subsequent repair is promoted. The mode is convenient and easy to operate, the mouth scanning system is well matched, and the operation time of doctors and the treatment time of patients are reduced. The directional scanning device disclosed by the invention is directly nested and connected with the drill needle, the applicability is wide, and the product is small and exquisite and does not occupy excessive intra-oral space.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and in particular relates to a device and method for orientable scanning for obtaining real-time positions of implant drills. Background technique [0002] The core process in the implant surgery process is the preparation of the implant cavity and the placement of the implant. Before the dental implant surgery, digital image inspection will be carried out first, and after the CT three-dimensional reconstruction of the upper and lower jaws, the bone quality and bone quality of the patient's operation area will be evaluated, and then combined with the position of the final restoration, the preparation of the implant cavity will be simulated. Determine the ideal placement direction and depth of the implant. During the operation, the operation is completed through several guidance methods such as free hand, static guide plate, and dynamic video navigation. Free hand operation means that th...

Problems solved by technology

These three verification methods have the following disadvantages: (1) Visual inspection is prone to misjudgment due to the influence of field of view, observation angle, individual anatomical features, and operator experience; (2) Imaging is performed under the premise of an open wound during surgery Inspection will increase the risk of infection in the operation area, increase the radiation exposure of the patient and the operation time, and the direction indication is poor, which is not conducive to the operator to establish a direct correspondence between the inspection results and the actual operation; (3) The equipment is expensive and the technology is sensitive High, not conducive to program promotion

[0005] In addition, as disclosed in the patent document "Dental Implant Guide Gauge (201410037034.8)", an intraoperative axial checking device is used for comparison. There is not a one-to-one correspondence, and in actual operation, the device is easily blocked by adjacent teeth, vestibular groove, and buccal tissue. There are many human factors in the measurement process, such as the sounding rod is not placed in place, and the needle tip is not fully reached. Bone surface, etc., there will be a large deviation in the measurement result itself, and the individualized jaw shape and thickness will also affect the rationality of the reference value range
