Description

Technical Field

[0001] The invention relates to a zygomatic drilling device, in particular to a special drilling device for quickly drilling through the zygomatic bone and a use method thereof. Background Art

[0002] Transzygomatic implant surgery is a technique for fixing dental implants by implanting them into the zygomatic bone. It is done by drilling holes in the upper zygomatic bone to increase the stability and success rate of the implant. The upper zygomatic bone is generally located below the eye socket on the face, usually the location of the apple muscle. Currently, most transzygomatic surgeries are performed in the patient's mouth. This method requires very strict drilling angles and depths by drilling upward through the zygomatic bone inside the mouth. Once a mistake is made, it is easy to injure the eye socket and cause a medical accident. In addition, the internal space of the human oral cavity is small and visibility is poor, which makes the surgery extremely difficult. When using a fixed-point drill, the surrounding mucoperiosteal flap may be rolled in, causing damage to the flap and causing accidental injury to the patient. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 4 The present invention provides a special drilling device for drilling zygomatic bone quickly, including a dental electric drill and a drill bit, a handle 1 and a protective tube 2, a through hole 3 for the drill bit to pass through is provided in the center of the protective tube 2, the size of the through hole 3 is larger than the size of the drill bit, so as to avoid the drill bit from rubbing against the inner wall of the protective tube 2 when working, the front end of the handle 1 is connected to the outer wall side of the protective tube 2, a limiting part is installed on the drill bit, and the protective tube 2 is provided with a distance mechanism matched with the limiting part. The device adopts the surgical mode of external zygomatic bone penetration, directly makes a small incision on the surface of the zygomatic bone outside the mouth, cuts the skin, slightly peels it, and then inserts the sleeve, directly prepares a hole on the surface of the zygomatic bone downward, communicates with the intraoral zygomatic bone penetration path, avoids the maxillary sinus mucosa (intraoral zygomatic bone penetration surgical skills are required), and goes down to the maxillary alveolar process to determine the path. Then, combined with the intraoral zygomatic bone penetration method, the next surgical steps can be continued from the inside of the mouth. The perforation path avoids the orbital position, thereby avoiding one of the most serious complications of transzygomatic surgery (damage to the orbit); the protective tube 2 can block the skin, periosteum and other tissues at the incision outside the drilling path of the drill bit, and the drill bit will not come into contact with the skin tissue during the drilling process, preventing the skin tissue from being drawn into the drill bit and causing additional damage, and the small extraoral incision is made along the skin texture, so no scars will be left after the operation.

[0027] The spacing mechanism includes a plurality of extension sleeves 4, a transition hole 5 is provided at the center of the extension sleeve 4, and the transition hole 5 has the same inner diameter as the through hole 3. A convex ring 6 is provided at the top of the extension sleeve 4, and a groove 7 is provided at the bottom of the extension sleeve 4. The convex ring 6 is also provided at the top of the protective tube 2. The extension sleeve 4 is plugged into the convex ring 6 of the protective tube 2 through the groove 7, and adjacent extension sleeves 4 are clamped by plugging the convex ring 6 into the groove 7. The protective sleeve is produced in modularized form with equal lengths, and protective tubes 2 of different lengths can be formed by plugging. In combination with the limiting part on the drill bit, the depth of advancement of the drill bit can be accurately controlled.

[0028] The limiting portion is a limiting tube 8 , and the limiting tube 8 is sleeved on the upper outer wall of the drill bit. The outer wall of the limiting tube 8 is larger than the inner diameter of the through hole 3 .

[0029] The drill bit includes a connected drill body 9 and a drill handle 10, the rotating handle is connected to the electric drill, the drill body 9 includes a working part 11 at the front end and a smooth part 12 at the rear end, the working part 11 is provided with a blade and a spiral groove, the blade is spirally provided with an anti-skid spine 13, and the limiting cylinder 8 is provided on the smooth part 12. The traditional drill bit is prone to slipping during the drilling process, and the added anti-skid spine 13 can improve the working stability of the drill bit and make the drill bit more stable during the drilling process.

[0030] The outer wall of the handle 1 is provided with anti-slip grooves 14 .

[0031] The handle 1 and the protective tube 2 are detachably connected, so the protective tube 2 can be replaced.

[0032] The front end of the protective tube 2 is provided with a conical docking joint 15, and the center of the docking joint 15 is provided with a docking hole 16. The docking hole 16 has the same diameter as the through hole 3 and is connected to the through hole 3. The docking joint 15 with a smaller hole diameter at the front end can be better inserted into the incision to effectively guide the drill bit.

[0034] S1: The maximum drilling depth is equal to the length from the front end of the drill bit to the limiter minus the overall length of the assembled protective tube 2. The protective tube 2 and the extension sleeve 4 can be assembled according to the pre-planned drilling depth;

[0035] S2: Use a scalpel to make an incision at the zygomatic bone position on the face, lift the skin and periosteum upwards, and expose the anterior and lateral wall of the zygomatic bone;

[0036] S3: holding the handle 1 and extending the protective tube 2 into the incision position, using the outer wall of the protective tube 2 to block the skin and periosteum from entering the drilling area;

[0037] S4: Connect the electric drill and the drill bit, start the electric drill to drive the drill bit to rotate, insert the drill bit into the through hole 3 of the protective tube 2, and drill the zygomatic bone downward along the angle of the through hole 3. When the limit part of the drill bit abuts against the top of the protective tube 2 or the extension sleeve 4, the drilling depth reaches the designed maximum depth, and the drilling work is completed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
