[0003] Most of the existing guides need to be separately fixed on the upper teeth, with poor fixing stability, and cannot be combined with other guides by magnetic attraction to improve the convenience and stability of fixing; most of the existing guides directly open guiding holes on the body, which cannot be reused, and depth limitation cannot be performed during drilling.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a magnetic guide for oral use is provided, in order to achieve a more practical purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a magnetic guide for oral use to solve the problems that most of the existing guides need to be separately fixed on the upper teeth, with poor fixing stability, and cannot be combined with other guides by magnetic attraction to improve the convenience and stability of fixing; most of the existing guides directly open guiding holes on the body, which cannot be reused, and depth limitation cannot be performed during drilling.

[0006] The present invention provides a magnetic guide for oral use, which specifically includes: a guide body; an arc-shaped hole is opened on the bottom end surface of the guide body, and two rectangular block-shaped first connection blocks are integrally formed on the guide body. A first guiding rod is fixed on the front end surface of each first connection block. A first connection tube slides on each first guiding rod. A threaded rod is welded to the bottom end surface of the outer wall of each first connection tube. Two first fixing nuts for positioning the first connection tube on the first guiding rod are threadedly connected to each first guiding rod. When the four first fixing nuts are tightened, the first connection tube is in a positioned state.

[0007] Further, a threaded tube is threadedly connected to the lower end of each threaded rod, and a clamping seat is rotated at the lower end of each threaded tube.

[0008] Further, two second guiding rods are welded in each clamping seat. Two clamping blocks slide on the two second guiding rods on the left side, and two clamping blocks also slide on the two second guiding rods on the right side. An adjusting rod is rotated on each clamping seat. The left and right sides of the adjusting rod are threadedly connected to the two clamping blocks respectively, and the thread directions on the left and right sides of the adjusting rod are opposite.

[0009] Further, the first connection block, the first guide rod, the first connection pipe, the threaded rod, the first fixing nut, the threaded pipe, the clamping seat, the second guide rod, the clamping block and the adjusting rod together form a support assembly.

[0010] Further, a connection assembly is installed on each of the first guide rods. The connection assembly is composed of a second connection pipe, a third guide rod, a connection arm, a second locking nut, a magnetic attraction seat and a third locking nut. A second connection pipe slides on each of the first guide rods, and a third guide rod is welded to the outer wall of the second connection pipe; two third locking nuts for positioning the second connection pipe are threadedly connected to each of the first guide rods. When the two third locking nuts are tightened, the second connection pipe is in a positioned state.

[0011] Further, a connection arm slides on each of the third guide rods, and two second locking nuts for positioning the connection arm are threadedly connected to each of the third guide rods. When the two second locking nuts are tightened, the connection arm is in a positioned state.

[0013] Further, a positioning assembly is installed on the first connection block. The positioning assembly is composed of a fourth guide rod, a second connection block, a connecting rod, a positioning seat and a fourth locking nut. A fourth guide rod in an arc-shaped rod structure is fixed on the two first connection blocks. Three second connection blocks slide on the fourth guide rod, and a screw rod for positioning the second connection block on the fourth guide rod is threadedly connected to each of the second connection blocks.

[0014] Further, a connecting rod slides on each of the second connection blocks. A positioning seat is welded to the lower end of each connecting rod. The positioning seat is located directly below the guide plate body. Two fourth locking nuts for positioning the connecting rod on the second connection block are threadedly connected to each of the connecting rods.

[0015] Further, three fixing screw rods are threadedly connected to the guide plate body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Height adjustability and positioning accuracy: Through the threaded connection design of the threaded rod and the threaded tube, medical staff can easily rotate the threaded tube to adjust the height of the clamping seat; this design is not only easy to operate, but also can accurately adapt to the oral structures and surgical needs of different patients, ensuring the stability of the support component during the operation; the adjustment rod cleverly utilizes the characteristic that the thread directions on the left and right sides are opposite, so that when the adjustment rod is rotated, the two clamping blocks can move synchronously and oppositely, thereby accurately clamping the lower teeth. This design greatly improves the positioning accuracy of the support and provides a reliable support basis for the operation.

[0018] Flexibility and adaptability: The sliding design of the first connecting tube on the first guiding rod and the locking mechanism of the first fixing nut enable the position of the support component to be flexibly adjusted according to the specific requirements of the operation; this design increases the adaptability of the device, enabling it to cope with the oral conditions and surgical plans of different patients; the design of the second connecting tube and the connecting arm in the connecting component also reflects flexibility; the second connecting tube can slide on the first guiding rod and is positioned by the third locking nut to achieve the adjustment of the front and rear positions of the connecting arm; while the sliding design of the connecting arm on the third guiding rod and the locking mechanism of the second locking nut allow the inclination angle of the connecting arm to be adjusted; this multi-dimensional adjustment ability enables the device to better fit the actual needs of the operation and improves the success rate and effect of the operation.

[0019] Convenience of magnetic adsorption fixation: The design of the magnetic adsorption seat is a major highlight of the device; since the magnetic adsorption seat is made of magnet material, it can be conveniently adsorbed on the osteotomy guide plate without complicated installation steps or additional fixing devices; this design not only simplifies the operation process, improves the operation efficiency, but also reduces the workload of medical staff.

[0020] Accuracy of drilling positioning: The design of the positioning component fully considers the requirements of the operation for the accuracy of the drilling position; the coordinated use of the fourth guiding rod, the second connecting block, the connecting rod and the positioning seat enables the drilling position to be accurately adjusted in three dimensions; medical staff can first adjust the position of the second connecting block on the fourth guiding rod according to the operation plan, and then adjust the height of the connecting rod on the second connecting block to ensure the accurate position of the positioning seat. Most importantly, after adjusting the height of the positioning seat, the drilling machine can be limited through the positioning seat, improving the drilling accuracy; this design greatly improves the accuracy and safety of the operation.

[0021] Patient comfort and stability: The design of the fixing screw on the guide plate body reflects the consideration for patient comfort; by rotating the fixing screw, the guide plate can be firmly clamped on the upper teeth, avoiding the movement or shaking of the guide plate during the operation; this design not only improves the stability of the operation, but also reduces the discomfort of the patient caused by the movement of the guide plate.
