Description

Technical Field

[0001] The utility model relates to the technical field of oral mirrors, in particular to a oral mirror structure. Background Art

[0002] Dental mirror is one of the most commonly used diagnostic and treatment tools in dentistry. Various routine oral examinations and treatments such as teeth cleaning, tooth extraction, and opening require the use of a dental mirror for observation.

[0003] Conventional dental mirrors have a simple structure, usually including a long handle with a mirror mounted on the end of the handle. The handle is usually slender, made of smooth metal or plastic, and has anti-slip grooves on the surface where it is held. During use, since the handle is relatively thin, the hand-held stability is poor and a certain amount of force is required to maintain it. Long-term use will cause fatigue and pain in the contact area of ​​the fingers. In addition, when used during surgery, gloves are usually worn, and the handle and fingers will slide relative to each other on the inside and outside of the gloves, resulting in poor overall stability. Although it does not absolutely affect use, it also needs to be optimized and improved. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 5 As shown, it comprises a mirror handle 1 and a handle cover 2 arranged on the mirror handle 1;

[0027] The handle sleeve 2 is provided with a protrusion structure, including a first protrusion 3, a second protrusion 4 and a third protrusion 5;

[0028] The first protrusion 3 and the third protrusion 5 are located on the same side of the circumference of the handle sleeve 2, and the first protrusion 3 and the third protrusion 5 are spaced apart from each other. The area formed by the spaced apart area is defined as a thumb groove. When holding the handle sleeve 2, the thumb is placed in the thumb groove, and the first protrusion 3 and the third protrusion 5 respectively abut against the upper and lower sides of the thumb.

[0029] Reference Figure 3 As shown, the first protrusion 3 and the third protrusion 5 are both distributed in a spiral structure, and the thumb groove is a rotary-cut structure surrounded by the first protrusion 3 and the third protrusion 5;

[0030] The tangent lines of the opposing surfaces of the first and third protrusions 3 and 5 are at the same angle to the horizontal, both between 30 and 50 degrees. When held, the thumb rests on the outside of the handle sleeve 2 in a tilted, downward position. The overall spiral structure matches this position. Furthermore, it provides a larger contact surface on both the upper and lower sides, ensuring stability. Furthermore, the spiral structure provides a more effective positioning effect, eliminating the need for a separate anti-slip structure around the thumb groove.

[0031] Continue to refer to Figure 3 As shown, a circular arc transition surface 31 is provided on the side of the first protrusion 3 close to the third protrusion 5, and a bevel surface 33 is provided on the side of the first protrusion 3 away from the third protrusion 5. The end of the bevel surface 33 is connected to the extension surface 32, and the end of the extension surface 32 intersects with the circular arc transition surface 31 through an arc chamfer 34.

[0032] When holding the handle, the thumb presses against the front of the handle sleeve 2, while the index finger wraps around the back of the handle sleeve 2, with the distal end of the index finger contacting the distal end of the thumb to hold the handle sleeve 2. Anti-slip grooves are provided on the surface of the thumb groove and the outer wall of the third protrusion 5 opposite the thumb groove to enhance stability. For easier cleaning, the anti-slip grooves can be omitted without affecting the user experience.

[0033] The beveled surface 33 is designed to avoid the index finger and prevent it from affecting the contact between the index finger and the handle sleeve 2. At the same time, the connection between the beveled surface 33 and the extension surface 32 provides guidance and support for the distal end of the index finger, so that it can abut against the distal end of the thumb stably.

[0034] The second protrusion 4 is provided on the circumference of the handle sleeve 2 on the other side of the first protrusion 3. When the handle sleeve 2 is held by hand, the outer side of the second protrusion 4 abuts against the inner side of the tiger's mouth. Figure 4 As shown, the upper portion of the second protrusion 4 is provided with a raised arc surface 41, and a guide slope 42 is provided on the side opposite to the arc surface 41. The end of the guide slope 42 forms an arc tip 43 at the bottom of the second protrusion 4. Figure 4 as well as Figure 2 As shown, when holding the device, the curved surface 41 rests against the base of the thumb, providing a certain degree of support and restraint at the base of the thumb. Furthermore, when holding the device, in addition to the index finger, the middle finger, ring finger, and pinky finger are also curled up. The guide bevel 42 provides guidance and support for the middle finger. The presence of the second protrusion 4 creates a gripping sensation between the middle finger and the base of the thumb, alleviating hand fatigue.

[0035] In addition, refer to Figure 2 As shown, the second protrusion 4 is located on the back side of the mirror surface. Therefore, in actual use, a bracket can be designed to embed the second protrusion 4 into the bracket and hang the mirror, which also solves the problem of mirror placement. The bracket is designed with a contoured groove that is wide at the top and narrow at the bottom, and the second protrusion 4 is inserted from top to bottom to limit the position.

[0036] Finally, the protrusion height of the first protrusion 3 is between 5mm-15mm, preferably 10mm, the protrusion height of the second protrusion 4 is between 10mm-15mm, preferably 15mm, and the protrusion height of the third protrusion 5 is between 5mm-10mm, preferably 5mm.

[0037] In another preferred embodiment of the present invention, the handle sleeve 2 is formed as a separate structure with a central opening. When in use, it is attached to the smooth handle 1 of the oral mirror. This reduces development costs. The handle sleeve 2 and the raised structure are both made of silicone or plastic, forming an integral structure.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
