Problems solved by technology

However, due to the high-speed rotation of the ball drill, it is easy to slip when it touches the bone surface
Once the high-speed rotating ball drill touches the adjacent tissue, it will inevitably cause damage to the adjacent tissue
And because it is easy to slip, it is difficult to control the dressing amount of the ball drill

Embodiment approach 1

[0034] The present application provides a bone trimmer.

[0035] The inventors of the present application found that, in the prior art, the bone repair methods adopted often cannot achieve good results. When using a ball drill to modify the bone surface, it is easy to slip, and the damage caused will significantly increase the pain of the patient, and may cause additional bone surface or soft tissue damage. However, some conventional alternative solutions cannot completely replace the role of the ball drill. For example, doctors sometimes use rongeurs to modify the bone surface, but the convenience of tools such as rongeurs is much worse than that of ball drills. Moreover, in some narrow spaces or corners, it is difficult for the beak of the rongeur to enter the trimming space, and the trimming effect cannot be exerted in all cases.

[0036] In order to solve the above problems, the first embodiment of the present application provides a bone trimmer, see figure 1 shown, inc...

Embodiment approach 2

[0055] The second embodiment of the present application provides a bone trimmer, the bone trimmer of the second embodiment is substantially the same as the bone trimmer of the first embodiment, the main difference is that in the first embodiment of the present application In the second embodiment of the present application, the guide rod 3 can be relatively fixedly connected with the bone trimming ring 2 and rotate coaxially with the bone trimming ring 2 ; while in the second embodiment of the present application, the guide rod 3 can freely rotate relative to the bone trimming ring 2 .

[0056] Although the guide rod 3 does not have the ability to grind, it will still exert force on the bone surface in the positioning hole 5 during the high-speed rotation following the bone trimming ring 2, causing discomfort to the patient. Therefore, when the guide rod 3 is set to be freely rotatable relative to the bone trimming ring 2, the rotation of the bone trimming ring 2 will not drive...

Embodiment approach 3

[0062] The second embodiment of the present application provides a bone trimmer, the bone trimmer of the third embodiment is substantially the same as the bone trimmer of the second embodiment, the main difference is that in the second embodiment of the present application Among them, the bone trimming ring 2 and the main body 1 are integrally formed; while in the third embodiment of the present application, see Figure 9 , Figure 10 As shown, the bone trimming ring 2 is formed with a sleeve hole 22 passing through the axis of rotation, and the bone trimming ring 2 is sleeved on the main body 1 through the sleeve hole 22;

[0063] An accommodating hole 12 is formed on the main body 1 at a position facing the sleeve hole 22;

[0064] The tail end of the guide rod 3 passes through the sleeve hole 22 and penetrates into the accommodating hole 12 , and the head end protrudes from the sleeve hole 22 .

[0065] Compared with the one-piece design, this solution enables the bone tr...

Abstract

The invention relates to the field of oral medicine, and provides a bone trimmer. The bone trimmer comprises a main body, a bone trimming ring and a guide rod; the main body is provided with an interface for externally connecting a rotary power device; the bone trimming ring sleeves the end part of one side of the main body so as to coaxially rotate along with the main body; the bone trimming ringis used for trimming a bone surface; and the guide rod is coaxially arranged relative to the bone trimming ring and is used for guiding and positioning the bone trimming ring. The bone trimmer provided by the embodiment of the invention has better safety and reliability.

Description

technical field [0001] The present application relates to the field of stomatology, in particular to a bone trimmer. Background technique [0002] With the development of oral implant technology, more and more patients use dental implants to restore missing teeth. In the case of oral implants, the doctor needs to use a drill bit that matches the patient's alveolar bone to prepare the drill hole, and then place the implant into the bone. [0003] During drilling preparation, the usual drilling accuracy is around 0.5mm. When the height of the alveolar bone is insufficient, it is even more necessary to control the depth of drilling to avoid damage to the nerves and blood vessels in the bone or bone perforation to expose the implant and fail the operation. [0004] At present, there are various brands of implants on the market. Although the design concepts are not the same, the implants are all standard cylindrical, and it is required that the implants be fully embedded in the...
