Description

Technical Field

[0001] This utility model relates to the field of surgical scalpel technology, and in particular to a multi-angle gingival scalpel. Background Technology

[0002] In the field of gingival surgery in dentistry, the gingival scalpel is an extremely crucial surgical instrument. Gingival surgery is mainly used to treat problems such as gingival recession and abnormal gingival morphology, and the precision of the surgery directly affects the patient's postoperative oral health and aesthetics.

[0003] Currently, existing membrane-gingival scalpels generally suffer from a significant drawback: a fixed blade angle. Each person's oral anatomy is unique, with substantial differences in the curvature of the palatal vault, the shape of the dental arch, and the location of the gingival flap. For example, some patients have a relatively gentle palatal vault curvature, while others may have a deeper and more complex one. With commonly used fixed-angle membrane-gingival scalpels, it is difficult to achieve the ideal operating angle in oral environments with varying palatal vault curvatures. This makes it difficult for surgeons to precisely cut and trim the gingival tissue during surgery. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle gingival scalpel to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A multi-angle gingival scalpel includes a handle, a base, a blade, and an angle adjustment mechanism. One end of the handle is connected to the base via the angle adjustment mechanism, and the blade is detachably mounted on the base.

[0007] The angle adjustment mechanism includes a knob, a limiting block, a limiting plate, a ball, an elastic element, and a connecting rod. One end of the knob is connected to the limiting block via the connecting rod, and one end of the limiting block is connected to the limiting plate via the elastic element. One end of the handle has a slot, and the ball is rotatably disposed within the slot. The limiting block is disposed within the ball. One outer wall of the slot has a mounting hole, and the other outer wall of the slot has a limiting hole. The knob is disposed within the mounting hole, and the limiting plate is disposed within the limiting hole.

[0008] Preferably, a fixing hole is provided in the middle of the sphere, and both the fixing hole and the limiting block have rectangular cross-sections.

[0009] Preferably, a first through hole is provided on the inner wall of the mounting hole, and the connecting rod passes through the first through hole.

[0010] As a further preferred embodiment, a plurality of first limiting protrusions are provided on the inner wall of the mounting hole, and the plurality of first limiting protrusions are provided on the periphery of the first through hole, and a second limiting protrusion is provided at one end of the knob to cooperate with the first limiting protrusions.

[0011] Preferably, the device also includes a telescopic rod, one end of which is provided with the telescopic rod, one end of which is connected to the limiting piece, and the elastic element is sleeved on the telescopic rod.

[0012] As a further preferred embodiment, a second through hole is provided on the inner wall of the limiting hole, through which the telescopic rod and the elastic element pass.

[0013] Preferably, the inner walls on both sides of the slot are provided with ball joint grooves that cooperate with the sphere.

[0014] Preferably, the outer wall of the knob is provided with anti-slip stripes.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] (1) In this utility model, by setting the angle adjustment mechanism, the angle of the blade holder can be flexibly adjusted, and then the angle of the blade can be adjusted.

Figure 1 ; Figure 5 This is a schematic diagram of the structure of the knife handle in this utility model. Figure 2 ; Figure 6 yes Figure 5 Please refer to the enlarged view at point A in the middle. Figures 1 to 6 As shown, a preferred embodiment is illustrated, illustrating a multi-angle gingival scalpel, including a handle 1, a base 2, a blade 3, and an angle adjustment mechanism 4. One end of the handle 1 is connected to the base 2 via the angle adjustment mechanism 4, and the blade 3 is detachably mounted on the base 2. In this embodiment, the handle 1 serves as the part held by the doctor, and its design fully considers ergonomic principles. The surface may be treated with anti-slip materials, such as anti-slip textures or anti-slip material, so that the doctor can comfortably and firmly grip the scalpel, reducing the risk of slippage due to sweaty hands or uneven force during surgery.

[0029] The angle adjustment mechanism 4 includes a knob 5, a limiting block 6, a limiting plate 7, a ball 8, an elastic element 9, and a connecting rod 10. One end of the knob 5 is connected to the limiting block 6 via the connecting rod 10, and one end of the limiting block 6 is connected to the limiting plate 7 via the elastic element 9. A slot 11 is provided at one end of the tool holder 1, and the ball 8 is rotatably disposed within the slot 11. The limiting block 6 is disposed within the ball 8. A mounting hole 12 is provided on one outer wall of the slot 11, and a limiting hole 13 is provided on the other outer wall of the slot 11. The knob 5 is disposed within the mounting hole 12, and the limiting plate 7 is disposed within the limiting hole 13. The slot 11 at one end of the tool holder 1 is used to accommodate the ball 8 in the angle adjustment mechanism 4, providing space for the rotation of the ball 8. The inner walls on both sides of the slot 11 are provided with ball joint grooves 20 that cooperate with the ball 8. The ball joint grooves 20 support and guide the ball 8, making the ball 8 rotate more smoothly and steadily in the slot 11, while limiting the range of motion of the ball 8 to ensure the stability and accuracy of its rotation.

[0030] The angle adjustment mechanism 4 allows adjustment of the angle of the tool holder 2, and consequently, the angle of the blade 3. This mechanism 4 controls the blade 3 to rotate along its thickness direction, not its width direction. For details, please refer to [link to relevant documentation]. Figure 2 As shown. The blade 3 is detachably connected to the blade holder 2, making it easy to replace different blades 3.

[0031] In this embodiment, the elastic element 9 is a tension spring, which provides a pulling force to the limiting block 6, thereby providing a pulling force for the knob 5 to move closer to the ball 8. The knob 5 and the connecting rod 10 are integrally formed, the connecting rod 10 and the limiting block 6 are welded and fixed, the limiting block 6 and the elastic element 9 are welded and fixed, the elastic element 9 and the limiting piece 7 are welded and fixed, and the limiting block 6 can slide within the ball 8.

[0032] Furthermore, as a preferred embodiment, a fixing hole 14 is provided in the middle of the sphere 8, and both the fixing hole 14 and the limiting block 6 have rectangular cross-sections. When the knob 5 is rotated, the knob 5 drives the limiting block 6 to rotate via the connecting rod 10, and the limiting block 6 drives the sphere 8 to rotate, which in turn drives the tool holder 2 to rotate, ultimately achieving the adjustment of the angle of the blade 3. The sphere 8 and the tool holder 2 are welded and fixed together.

[0033] Furthermore, as a preferred embodiment, a first through hole 15 is provided on the inner wall of the mounting hole 12, through which the connecting rod 10 passes. The first through hole 15 facilitates the passage of the connecting rod 10, which can rotate or move within the first through hole 15.

[0034] Furthermore, as a preferred embodiment, a plurality of first limiting protrusions 16 are provided on the inner wall of the mounting hole 12, and the plurality of first limiting protrusions 16 are provided around the first through hole 15. One end of the knob 5 is provided with a second limiting protrusion 17 that cooperates with the first limiting protrusions 16. A plurality of first limiting protrusions 16 and second limiting protrusions 17 are provided, and each first limiting protrusion 16 can be operably inserted between two adjacent second limiting protrusions 17 to lock the first limiting protrusion 16. This can lock the angle of the knob 5 and prevent the ball 8 from rotating.

[0035] When the angle needs to be adjusted, first pull the knob 5 outward to overcome the tension of the spring, causing the first limiting protrusion 16 to disengage from the second limiting protrusion 17. Then, rotate the knob 5. The knob 5 drives the limiting block 6 to rotate via the connecting rod 10. The limiting block 6 drives the ball 8 to rotate, ultimately driving the blade 3 to rotate. After adjusting the angle of the blade 3 to the appropriate position, release the knob 5. Under the action of the spring, the limiting block 6 moves inward toward the ball 8, thereby driving the connecting rod 10 to move. The connecting rod 10 drives the knob 5 to move closer to the ball 8, so that the second limiting protrusion 17 on the knob 5 cooperates with the first limiting protrusion 16 in the mounting hole 12 to fix the angle of the knob 5, and ultimately fix the angle of the blade 3. In this embodiment, the surface of the limiting piece 7 near the limiting hole 13 can be an arc-shaped surface or a spherical surface, which facilitates the rotation of the limiting piece 7.

[0036] Furthermore, as a preferred embodiment, it also includes a telescopic rod 18. One end of the limiting block 6 is provided with the telescopic rod 18, and one end of the telescopic rod 18 is connected to the limiting piece 7. The elastic element 9 is sleeved on the telescopic rod 18. The telescopic rod 18 is located in the fixing hole 14 on the ball 8 and can extend and retract along the axial direction of the fixing hole 14. It is used to guide the elastic element 9, ensuring that the elastic element 9 will not shift during the extension and retraction process, thereby enhancing the stability of the overall structure.

[0037] Furthermore, as a preferred embodiment, a second through hole 19 is provided on the inner wall of the limiting hole 13, through which the telescopic rod 18 and the elastic member 9 pass.

[0038] Furthermore, as a preferred implementation, the outer wall of the knob 5 is provided with anti-slip stripes, making it convenient for doctors to pull the knob 5 outward with their fingers.

[0039] During the surgical procedure, the surgeon first pulls the knob 5 outward with their fingers, based on the curvature of the palatal vault inside the patient's mouth and the surgical requirements. Then, they rotate the knob 5 to adjust the angle of the blade 3. After the angle is adjusted, the knob 5 is released. With the cooperation of the elastic element 9, the first limiting protrusion 16, and the second limiting protrusion 17, the angle of the knob 5 is fixed, and the blade 3 is also fixed. The surgeon can then hold the handle 1 and use the adjusted blade 3 to perform precise cutting and trimming of the patient's gingival tissue.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
