Description

Device and method for obtaining orientable scanning of real-time position in implantation drilling needle operation
Technical Field
The invention belongs to the technical field of implant teeth, and particularly relates to a device and a method for acquiring real-time position orientable scanning in an implant drilling needle operation.
Background
The most central process in the dental implant surgery process is the preparation of an implant cavity and the implantation of an implant. Before the dental implant operation, firstly, digital image examination is carried out, after CT three-dimensional reconstruction of upper and lower jawbones, the condition of bone mass in an operation area of a patient is evaluated, then, the preparation of an implant cavity is simulated by combining the position of a final restoration, and the ideal implantation direction and depth of an implant are determined. The operation is completed in the operation through a plurality of guiding modes such as free hands, static guide plates, dynamic video navigation and the like. The free hand operation means that an operator holds an implantation operation tool (an implantation mobile phone) by hand and performs operation in the oral cavity of a patient according to own experience and hand feeling. The method lacks accurate and stable guidance, and easily causes overlarge deviation between the actual implant position of the implant and the preoperative planning scheme, thereby influencing the smooth implementation of the subsequent repair scheme. Although the static guide plate can restrict the position and the angle of the drill point to a certain extent, the guide plate-guided implantation operation has the defects of difficult heat dissipation, limited operation space, narrow visual field, insufficient flexibility, high opening degree requirement and the like. Meanwhile, as the drill point has a certain moving range in the guide plate lantern ring, the cavity preparation guided by the guide plate has deviation, but the cavity preparation does not have the functions of checking and correcting, and the deviation accumulation causes that the position of the postoperative implant is difficult to keep consistent with the preoperative design; the dynamic navigation brings the implant mobile phone, the patient operation area and the preoperative design into the same coordinate system, can realize the real-time tracking of the positions of the drill point and the implant, and guides a doctor to accurately complete the operation. Because the doctor needs to look at the screen to operate in the art, the relevant navigation equipment is expensive, and the use complexity is higher. In addition, the guiding precision of the dynamic navigation is the cooperation between the doctor and the equipment, and since the guiding preparation and the implantation have no rigid and stable constraint, the precision of the dynamic navigation guiding implantation operation has similar deviation.
The existing scanning device is mainly designed based on different implant systems, aims to obtain the actual position of a post-operation implant in a jaw bone, belongs to the repair stage after the implant operation at the moment, and cannot be used for scanning and checking the implant before implantation due to the special interface design matched with the implant.
The existing intraoperative examination mainly comprises the following three modes: (1) in the operation, an axial indicating rod is used for referring to adjacent teeth and visually checking the axial direction and the depth of the prepared cavity of the jaw teeth; (2) after preparation of a certain stage is completed, an axial indication rod is inserted to shoot the tip slice for inspection; (3) intra-operative verification under dynamic navigation guidance. These three verification methods have the following disadvantages: (1) the visual inspection is easily influenced by the visual field of the operation area, the observation angle, the personalized anatomical features and the experience of the operator to generate misjudgment; (2) the image examination is carried out on the premise of opening the wound in the operation, so that the risk of infection in the operation area is increased, the radiation exposure and the operation time of a patient are increased, the direction indication is poor, and the direct corresponding relation between the examination result and the actual operation is not favorably established by an operator; (3) the equipment is expensive, the technical sensitivity is high, and the scheme is not favorable for popularization.
In addition, an intraoperative axial checking device is disclosed in patent document "dental implantation guide gauge (201410037034.8)", the jaw thickness safety range for comparison is estimated based on an average value, so that the measurement result and the axial direction do not correspond to each other one to one, the device is easily blocked by adjacent teeth, vestibular sulcus and tissues on labial and buccal sides in actual operation, the measurement process is interfered by more artificial factors, for example, a depth rod is not placed in place, a needle point does not completely abut against a bone surface, the measurement result itself has larger deviation, and the personalized jaw shape and thickness also influence the rationality of the reference value range.
