Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an array device for positioning a dental machine. Background Art

[0002] In recent years, with the rapid development of neuroimaging, display technology, computer and other sciences, dental implant machines have become increasingly mature. As surgical equipment used by dentists for oral implants, they are now widely used in various dental clinics.

[0003] At present, a dental implant machine includes an optical positioning camera, a dental machine and a reference array connected to the dental machine. The reference array and the dental machine are rigidly fixedly connected. The reflective markers on the reference array reflect the infrared light signal to the optical positioning camera. The optical positioning camera determines the position of the dental machine based on the received infrared light signal to calibrate the position of the dental machine drill, thereby facilitating precise implantation of the dental machine under navigation.

[0004] The existing reference array and the dental machine are fixedly connected, so that the position of the reflective marker on the reference array is fixed relative to the dental machine. When implanting different teeth (such as maxillary implants and mandibular implants), the optical positioning camera cannot capture the infrared light signal reflected by the reflective marker on the reference array during individual implant angle operations, thereby being unable to accurately obtain the position of the dental machine drill, resulting in low accuracy of the implant surgery or even the inability to perform the surgery. Summary of the invention

[0005] The present application provides an array device for positioning a dental machine, which solves the problem in the prior art that the reference array and the dental machine are fixedly connected, making it impossible to accurately obtain the position of the dental machine drill when operating at individual implant angles, resulting in low precision of implant surgery or even inability to perform the surgery.

[0006] The present application provides an array device for positioning a dental machine, comprising a reference array and a clamp, wherein the reference array is detachably mounted on the dental machine via the clamp; the clamp comprises a first clamp and a second clamp, wherein the first clamp and the second clamp cooperate to form a clamp structure, and the first clamp and the second clamp are fixed to the tail of the dental machine via bolts.

[0007] In the technical solution provided in the present application, the reference array is fixed to the tail of the dental machine by the cooperation of the first clamp and the second clamp to form a clamp structure. When implanting different teeth (such as implanting the mandibular first and then the maxillary implant), the relative position of the reference array and the dental machine can be adjusted by loosening the bolts and then fixed. During the implantation process, the infrared light signal reflected by the reflective marker on the reference array can be captured by the optical positioning camera, thereby ensuring the accuracy of surgical navigation positioning.

[0008] In some embodiments, a shell is installed on the outside of the clamp, and the shell includes a first shell and a second shell. The first shell is detachably connected to the clamp, and the second shell is detachably connected to the first shell. The reference array is connected to the first shell or the second shell via a connecting arm. By detachably connecting the shell to the outside of the clamp, the reference array is easily installed, and the overall aesthetics of the device is improved.

[0009] In some embodiments, a first connecting block is provided on the top of the first shell, a positioning groove is provided in the middle of the top surface of the first connecting block, and screw holes are provided on both sides of the positioning groove; a second connecting block is provided at the bottom of the connecting arm, a positioning block matching the positioning groove is provided in the middle of the bottom surface of the second connecting block, and through holes matching the screw holes are provided on both sides of the positioning block, and the first connecting block and the second connecting block are connected by screws; by providing the first connecting block and the second connecting block, it is convenient to detachably connect the reference array to the shell through the connecting arm, and by providing the positioning groove and the positioning block, it is convenient to quickly position the first connecting block and the second connecting block, thereby improving assembly efficiency.

[0010] In some embodiments, a retaining ring is connected to one end face of the first clamp or the second clamp, and a ring sleeve is coaxially provided on the outer end face of the retaining ring; the first shell is annular, and a limiting ring is provided on the inner wall of the first shell, the inner diameter of the limiting ring matches the outer diameter of the ring sleeve, and the inner diameter of the limiting ring is smaller than the outer diameter of the retaining ring, and the limiting ring sleeve of the first shell is provided on the ring sleeve; by arranging a retaining ring on one side of the clamp and cooperating the ring sleeve with the limiting ring on the inner wall of the first shell, the first shell can be positioned, and the assembly of the first shell and the second shell is convenient.

[0011] In some embodiments, the outer wall of the ring sleeve is provided with a key block, and the inner wall of the limit ring is provided with a key slot matching the key block. By arranging the key block and the key slot to cooperate, the limit ring and the ring sleeve can be prevented from rotating, thereby improving the stability of the reference array installation.

[0012] In some embodiments, there are multiple key slots, and the multiple key slots are evenly arranged along the circumference of the inner wall of the limit ring. By providing multiple key slots on the inner wall of the limit ring, when it is necessary to adjust the installation position of the reference array, the key slot that cooperates with the key block can be directly replaced without disassembling the clamp, which makes the operation more convenient. After adjusting the installation position of the reference array, there is no need to calibrate the position of the dental drill needle again, thereby improving the surgical efficiency.

[0013] In some embodiments, the second shell is sleeved on the outside of the clamp, and one end of the second shell is provided with an external thread, and one end of the first shell is provided with an internal thread matching the external thread, and the first shell and the second shell are connected by threads to facilitate the assembly of the first shell and the second shell.

[0014] In some embodiments, the outer surface of the second shell is hemispherical, and an opening for the dental machine to pass through is provided in the middle of the second shell. By designing the outer surface of the second shell to be hemispherical, the overall aesthetics of the device is improved.

[0015] In some embodiments, the outer wall of the second shell is evenly provided with a plurality of slots along the circumference, and the plurality of slots are used to cooperate with a wrench to install or remove the second shell.

[0016] In some embodiments, the reference array includes an optical bracket, on which no less than three reflective markers are asymmetrically arranged, ensuring that the optical positioning camera can simultaneously capture infrared light signals reflected by at least three reflective markers on the reference array, thereby ensuring positioning accuracy.
