Description

Technical Field

[0001] The utility model relates to an auxiliary instrument in the field of oral implant, in particular to a novel gingival soft tissue circumcision tool. Background Art

[0002] In current clinical applications, soft tissue circumcision tools are widely used in dental and surgical operations, especially when dealing with soft tissues in the oral cavity. Common soft tissue circumcision tools usually adopt a flat circular blade design. However, this traditional flat circular blade exposes some deficiencies and limitations during actual operation, which are specifically manifested in the following aspects: First, the texture of the gingival soft tissue is relatively soft, with a certain degree of mobility and high toughness. These physical properties make it relatively difficult for the traditional flat circular blade to cut into the soft tissue during soft tissue circumcision. The operator needs to apply relatively large pressure and must continuously press to slowly cut into the soft tissue. This not only increases the operation difficulty and fatigue, but also, during a long operation, it is easy to cause the doctor to have a poor operation feel and increase the inconvenience of operation. Continuous forced operation may also increase the patient's discomfort and postoperative recovery time. Second, since the surface of the alveolar bone is not flat but has uneven features, this further increases the operation difficulty of the flat circular blade. When circumcising the concave part of the gingival soft tissue, it is difficult for the flat circular blade to cut completely in place. In this case, the incompletely cut soft tissue will affect the complete removal of the circular soft tissue after circumcision, resulting in the residue of the circumcised soft tissue. This residue needs to be processed secondarily, which not only increases the operation time, but also may affect the accuracy of the operation and the quality of the patient's postoperative recovery. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies in the prior art and provide a gingival soft tissue circumcision knife for quickly separating gingival soft tissue and shortening the operation time.

[0004] To solve the above technical problems, the utility model provides a gingival soft tissue circumcision knife, which includes a circumcision blade;

[0005] The circumcision blade includes a blade edge extending along the circumferential direction. The circumcision blade can rotate along the circumferential direction. The blade edge is wavy and has at least two wave crests and two wave troughs. The blade edge forms an inclined blade between the wave crest and the wave trough;

[0006] There is a height difference along the axial direction between the wave crest and the wave trough.

[0007] In a better embodiment, the height difference measured axially between the wave crest and the wave trough is between 0.3 mm and 1 mm.

[0008] In a more preferred embodiment, the circumcision knife includes a top wall and a surrounding wall, and the end of the surrounding wall includes the cutting edge; a storage bin is formed between the top wall and the surrounding wall.

[0009] In a more preferred embodiment, the surrounding wall is further provided with one or more through holes, and the through holes are connected to the storage bin.

[0010] In a more preferred embodiment, a handle is further included. One end of the handle is fixedly connected to the top wall, and a connection interface is provided at the other end of the handle.

[0011] In a more preferred embodiment, the wave crests are arranged at uniform intervals along the circumferential direction; the wave troughs are arranged at uniform intervals along the circumferential direction.

[0012] In a more preferred embodiment, the tops of the wave crests are on the same horizontal plane.

[0013] Compared with the prior art, the technical solution of the present utility model has the following beneficial effects:

[0014] A gingival soft tissue circumcision knife includes a circumcision blade; the circumcision blade includes a cutting edge extending along the circumferential direction, the circumcision blade can rotate along the circumferential direction, the cutting edge is wavy and has at least two wave crests and two wave troughs, and the cutting edge forms an inclined blade between the wave crests and the wave troughs; there is a height difference between the wave crests and the wave troughs along the axial direction. The wavy cutting edge of the present utility model changes the working mode of the circular cutting edge that synchronously forces the whole to cut into the gingival soft tissue. The wavy cutting edge focuses on cutting into the gingival soft tissue through the wave crest as a local force point, and then the inclined blade between the wave crest and the wave trough performs longitudinal and transverse synchronous sliding cutting, thereby forming a multi-point circumcision with dispersed force. Slightly pressing down the wavy circumcision knife can easily cut open the gingival soft tissue. At the same time, the cutting edge of the wave crest can also cut the soft tissue close to the concave part of the alveolar bone, so that the cut soft tissue can be easily removed. It can improve the circumcision efficiency of the gingival soft tissue and shorten the operation time; improve the doctor's operation experience and the patient's intraoperative feeling.

[0018] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0019] A gingival soft tissue circular cutter comprises a circular cutting blade and a handle 2. The circular cutting blade comprises a top wall 12 and a surrounding wall 13. The distal end of the surrounding wall 13 forms a cutting edge 11 extending circumferentially. One end of the handle 2 is fixedly connected to the top wall 12, and the other end of the handle 2 is provided with a connection interface. The connection interface can be used to connect to a slow-speed dental handpiece, driving the circular cutting blade to rotate circumferentially.

[0020] The cutting edge 11 is wavy and has at least two crests 111 and two troughs 112. The cutting edge 11 forms a beveled edge 113 between the crests 111 and the troughs 112. There is a height difference H between the crests 111 and the troughs 112 along the axial direction. The circular cutting knife in the present invention adopts a wavy cutting edge design, with at least two crests 111 and two troughs 112, forming multiple beveled edges 113. This design makes the cutting edge 11 no longer flat, but can effectively apply cutting force to the gingival soft tissue during the cutting process, thereby improving the cutting efficiency. The height difference H between the crests 111 and the troughs 112 can produce differentiated pressure distribution during the cutting process, making the cutting process smoother and more efficient. Especially when facing an uneven alveolar bone surface, this design can better adapt to the natural shape of the gums and reduce incomplete cutting. The wavy cutting edge 11 of the present invention changes the working mode of the circular cutting edge 11 in which the whole circular cutting edge is synchronously forced to cut into the gingival soft tissue. The wavy cutting edge 11 uses the wave crest 111 as a local fulcrum to concentrate on cutting into the gingival soft tissue, and then the inclined edge 113 between the wave crest 111 and the wave trough 112 performs longitudinal and transverse synchronous sliding cutting, thereby forming a multi-point circular cutting with dispersed force. The gingival soft tissue can be easily cut by slightly pressing down the wavy circular cutting knife. At the same time, the wave crest 111 of the cutting edge 11 can also cut the soft tissue close to the alveolar bone recess, so that the soft tissue after circular cutting can be easily removed.

[0021] In this embodiment, the height difference H between the crest 111 and the trough 112 measured in the axial direction is between 0.3 mm and 1 mm. This range is set based on the requirement for better effect of the bevel blade 113 in actual gingival soft tissue cutting and the safety of the operation. Too large a height difference H will make the cutting edge 11 too sharp and the bevel blade 113 too steep, resulting in axial jump of the soft tissue cutting knife during the cutting process, increasing the risk of trauma to the patient; while too small a height difference H may not achieve the expected cutting effect. Therefore, this range of height difference H can reduce damage to the gums while ensuring the cutting effect.

[0022] In this embodiment, a storage bin 14 is formed between the top wall 12 and the surrounding wall 13. During the cutting process, it can effectively store the cut soft tissue, preventing it from scattering in the surgical area, thereby maintaining the cleanliness and visibility of the surgical area, reducing the operation time and potential infection risks. More specifically, one or more through holes 131 are provided on the surrounding wall 13, and the through holes 131 are connected to the storage bin 14. This further optimizes the function of the soft tissue circumcision knife. These through holes 131 are connected to the storage bin 14, enabling the cut soft tissue to smoothly pass through the through holes 131, facilitating its removal from the storage bin 14, and improving the neatness and efficiency of the operation.

[0023] In this embodiment, the wave peaks 111 are evenly spaced along the circumferential direction; the wave valleys 112 are evenly spaced along the circumferential direction. The wave peaks 111 and the wave valleys 112 are evenly distributed in the circumferential direction, ensuring a uniform distribution of the cutting force throughout the circumcision process. This design of evenly spaced arrangement can reduce the single-point stress, prevent excessive wear at a certain position, and at the same time increase the smoothness and efficiency of cutting.

[0024] In this embodiment, the tops of the wave peaks 111 are on the same horizontal plane. The design that the tops of the wave peaks 111 are on the same horizontal plane ensures that during the circumcision operation, all the wave peaks 111 come into contact with the soft tissue simultaneously, providing a consistent cutting depth and force. This design further improves the cutting efficiency and precision of the circumcision knife, especially prominent when it is necessary to quickly and precisely excise the gingival soft tissue.

[0025] Refer to Figure 3 , after the handle 2 of the gingival soft tissue circumcision knife is installed on the dental slow handpiece, it is held by the doctor and the gingival soft tissue circumcision knife is aligned with the affected area of the patient. The gingival soft tissue circumcision knife rotates and slightly presses down with force, and the wave peaks 111 locally focus the force and cut in. Refer to Figure 4 , during the rotation of the gingival soft tissue circumcision knife, the inclined edge 113 of the circumcision edge slides horizontally around the axis and cuts, and slides longitudinally along the direction of the applied pressure.

[0026] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making non-substantive modifications to the present invention using this concept, shall fall within the scope of infringement of the protection of the present invention.
