Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable drill for dental implant surgery. Background Technique

[0002] Oral dental implant technology refers to a tooth replacement method that supports and retains the upper dental prosthesis based on the lower structure implanted in the bone tissue. It includes two parts: the lower support implant and the upper dental prosthesis. An implant (generally similar to the shape of a tooth root) is made of artificial materials (such as metals, ceramics, etc.), and is implanted into the tissue (usually the upper and lower jaws) through a surgical method and obtains firm retention support from the bone tissue. The upper dental prosthesis is connected and supported through special devices and methods.

[0003] When performing dental implant surgery, a dental drill is used as a drill for drilling holes. When a dentist holds the dental drill for dental implant surgery, the palm sizes of each dentist are different. When a dentist holds a dental drill with a fixed size, a long or short palm cannot obtain a good grasping size at the dental drill, and thus there is a certain discomfort in grasping when the dental drill is held by the dentist. Moreover, during dental implant surgery, when the patient is stimulated and closes the mouth, the teeth are likely to bite on the hard shell of the drill head, resulting in occlusal damage to the drill head or the patient's teeth. For this reason, we propose an adjustable drill for dental implant surgery. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an adjustable drill for dental implant surgery. A threaded handle is provided at the drill handle of the drill used as a drill. A sleeve handle that can be screwed is provided to match the threaded handle. The depth of the screw sleeve of the threaded handle and the sleeve handle can be adjusted at the drill handle, so that the length of the drill used as a drill during dental implant surgery can be adjusted. And after the sheath is sleeved with a hard board through the inner filling groove, it can be sleeved outside the drill head for protection, effectively reducing the contact damage between the drill head and the teeth, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An adjustable drill for dental implant surgery, comprising a drill handle and a drill bit, further comprising a threaded handle, a sleeve handle and a sealing plate. One end of the drill handle at the inclined neck rod is provided with a drill bit, and the other end of the drill handle far from the drill bit is fixed with a threaded handle. The outer surface of the threaded handle is sleeved with a sleeve handle, and a sealing plate is welded at one end of the sleeve handle. A guide post welded on the surface of the sealing plate is embedded in the sleeve handle, and a spring is sleeved outside the column body of the guide post. The guide post and the spring are embedded in a guide hole opened inside the threaded handle. A ribbed plate is welded on the outer surface of the sleeve handle. A wrapper is adhesively bonded around the outer shell of the drill bit, and an inner filling groove is recessed in the body of the wrapper. A hard wrapper plate is embedded in the inner filling groove.

[0007] Further, the body of the wrapper is a soft body, and the inner filling groove of the wrapper has the same size as the hard wrapper plate; the soft body of the wrapper obtains hard support through the hard wrapper plate at the inner filling groove.

[0008] Further, three groups of ribbed plates are welded at three points on the surface of the sleeve handle; three groups of ribbed plates outside the sleeve handle are welded to increase the gripping friction points.

[0009] Further, the diameter of the hole body of the guide hole is the same as the outer diameter of the spring coil of the spring, and the length of the spring body of the spring is greater than the length of the hole cavity of the guide hole; the spring can be adaptively embedded in the guide hole, and the longer spring can maintain elastic support between the guide hole and the sealing plate.

[0010] Further, a threaded hole is machined inside the sleeve handle, and a threaded handle is screwed into the threaded hole of the sleeve handle; the sleeve handle can be screwed to the threaded handle by means of its own threaded hole.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] By providing a threaded handle at the drill handle used as a drill, and a sleeve handle that can be screwed on the threaded handle, the depth of screwing of the threaded handle and the sleeve handle can be adjusted at the drill handle, so that the drill used as a drill during dental implant surgery can be adjusted in length. And after the wrapper is sleeved with a hard wrapper plate through the inner filling groove, it can be sleeved outside the drill bit for protection, effectively reducing the contact damage between the drill bit and the teeth.

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] As Figures 1-3 shown, an adjustable drill for dental implant surgery includes a dental drill handle 1 and a dental drill bit 2, and also includes a threaded handle 3, a sleeve handle 4 and a sealing plate 5. One end of the dental drill handle 1 at the inclined neck rod is provided with a dental drill bit 2, and the other end of the dental drill handle 1 away from the dental drill bit 2 is fixed with a threaded handle 3. The outer surface of the threaded handle 3 is sleeved with a sleeve handle 4, and a sealing plate 5 is welded at one end of the sleeve handle 4. A guide post 6 welded on the surface of the sealing plate 5 is embedded in the sleeve handle 4, and a spring 7 is sleeved outside the column body of the guide post 6. The guide post 6 and the spring 7 are embedded in a guide hole 8 opened inside the threaded handle 3. A ribbed plate 9 is welded on the outer surface of the sleeve handle 4. The outer shell of the dental drill bit 2 is surrounded and adhered with a sleeve 10, and an inner filling groove 11 is recessed in the sleeve body of the sleeve 10. A hard wrapping plate 12 is embedded in the inner filling groove 11.

[0019] Among them, the sleeve body of the sleeve 10 is a soft sleeve body, and the inner filling groove 11 of the sleeve 10 has the same size as the hard wrapping plate 12; the soft sleeve body of the sleeve 10 obtains hard support through the hard wrapping plate 12 at the inner filling groove 11.

[0020] Among them, the ribbed plate 9 is welded in three groups at three points on the surface of the sleeve handle 4; there are three groups of ribbed plates 9 welded outside the sleeve handle 4 to increase the grasping friction points.

[0021] Among them, the hole diameter of the guide hole 8 is the same as the outer spring diameter of the spring 7, and the spring body length of the spring 7 is greater than the hole cavity length of the guide hole 8; the spring 7 can be adaptively embedded in the guide hole 8, and the longer spring 7 can maintain elastic support between the guide hole 8 and the sealing plate 5.

[0022] Among them, a threaded hole is machined inside the sleeve handle 4, and the threaded handle 3 is screwed into the threaded hole of the sleeve handle 4; the sleeve handle 4 can be screwed to the threaded handle 3 by means of its own threaded hole.

[0023] It should be noted that the present utility model is an adjustable drill for dental implant surgery. A threaded handle 3 is provided at the drill handle 1 used as a drill.
