Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a highly stable and heat-dissipating dental drill. Background Technology

[0002] A dental drill is a commonly used instrument in dental surgery, primarily used to repair and treat various dental problems. It plays an important role not only in traditional dental treatments but also in minimally invasive surgeries. There are many types of dental drills, including mechanical, ultrasonic, and laser drills, each with its unique advantages and applications. Dental drills assist dentists in drilling and enlarging holes in the human body. The excellent heat dissipation and high stability of dental drills greatly improve the success rate of surgeries.

[0003] However, in actual use, existing dental drills have poor chip removal capabilities, and the residue rubs against the blade inside the body, affecting heat dissipation and the precision of the blade; at the same time, the poor stability of the blade can easily lead to medical accidents.

[0004] Therefore, the above-mentioned problems are technical issues that urgently need to be addressed. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above deficiencies, this utility model provides a highly stable and heat-dissipating dental drill, thereby improving the stability and heat dissipation of the dental drill and solving the above technical problems.

[0006] Technical solution: In order to achieve the above objectives, this utility model provides a highly stable and heat-dissipating dental drill, including a drill body and a shank;

[0007] The blade body and the handle are connected. The blade body includes a blade tip at its end. The blade body is also provided with at least three sets of chip removal grooves. The chip removal grooves are arranged in a circular array with the center of the blade body as the axis. One section of the chip removal groove starts from the blade tip and extends to the tail of the blade body.

[0008] The blade tip is provided with a chip-collecting groove, which is connected to the chip-removing groove.

[0009] Furthermore, the cutting tool body is provided with a back edge, and the back edge is provided with a clearance angle, the angle of which is 15°~25°. The clearance angle plays an important role in reducing friction, improving cutting efficiency, enhancing drill bit durability, and optimizing chip removal.

[0010] Furthermore, the blade tip is conical, and the chip removal groove is spirally arranged.

[0011] Furthermore, the diameter of the blade tip gradually increases from top to bottom, and the diameter of the bottom of the blade tip is the same as the diameter of the blade body.

[0012] Furthermore, the angle of the chip groove is 50°~70°. The chip groove can assist in the discharge of residue, improve cutting performance, and increase tool life.

[0013] Furthermore, the surface of the cutting tool body is coated with a titanium oxide coating. The titanium oxide coating can significantly improve the tool's wear resistance, adhesion, and high-temperature resistance.

[0014] Furthermore, it also includes a center hole, which is coaxial with the axis of the blade body and extends through both the blade body and the handle. The center hole effectively improves heat dissipation efficiency and also serves as a guide hole.

[0015] Furthermore, the tool holder is provided with a quick-connect plug at its tail. The tool holder is connected to the power device via this quick-connect plug.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0017] This invention provides a highly stable and heat-dissipating dental drill. It features a conical drill bit with a circumferential cutting edge back angle of 15°-25° and adds a chip removal groove to reduce the friction between the drill bit and the material inside the body. This design improves heat dissipation and enhances the precision of the drill. The hollow shape of the drill also significantly improves processing stability and reduces medical accidents caused by tool-related issues. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the structure of a highly stable and heat-dissipating dental drill according to the present invention.

[0019] In the diagram: 1-blade body, 2-handle, 3-chip removal groove, 4-blade tip, 5-chip collection groove, 6-center hole, 7-blade back. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figure 1 As shown: A highly stable and heat-dissipating dental drill includes a drill body 1 and a shank 2;

[0022] The blade body 1 and the handle 2 are connected. The blade body 1 includes a blade tip 4 at its end. The blade body 1 is also provided with at least three sets of chip removal grooves 3. The chip removal grooves 3 are arranged in a circular array with the center of the blade body 1 as the axis. One section of the chip removal groove 3 starts from the blade tip 4 and extends to the tail of the blade body 1.

[0023] The blade tip 4 is provided with a chip-collecting groove 5, which is connected to the chip-removing groove 3.

[0024] The chip removal groove 3 and chip receiving groove 5 in this utility model can effectively remove the residue generated during drilling, prevent the tool from overheating, and at the same time reduce the friction between the tool and the residue to improve the tool's accuracy.

[0025] In a further optimized design, the cutter body 1 is provided with a back edge 7, and the back edge 7 is provided with a clearance angle, the angle of which is 15°~25°. The main function of the clearance angle is to reduce the friction between the drill bit's back face and the machined surface. The clearance angle can reduce the contact area between the drill bit's back face and the hole wall, thereby reducing friction and heat generation; the clearance angle helps to maintain the smoothness of the cutting process; during use, the drill bit is subjected to a large cutting force and friction, which will cause wear on the cutting tip 4. The clearance angle can reduce the contact between the cutting tip 4 and the hole wall, thereby reducing the wear of the cutting tip 4 caused by friction. This design not only extends the service life of the drill bit, but also maintains the accuracy and quality of drilling; in addition, the clearance angle reduces the friction between the drill bit and the hole wall, providing more space for chip removal, which helps to facilitate the smooth removal of chips, thereby avoiding drilling quality problems caused by chip blockage.

[0026] Preferably, the blade tip 4 is conical, and the chip removal groove 3 is spirally arranged.

[0027] Specifically, the diameter of the blade tip 4 gradually increases from top to bottom, and the bottom diameter of the blade tip 4 is the same as the diameter of the blade body 1.

[0028] The chip groove 5 has an angle of 50° to 70°. The main function of the chip groove 5 is to smoothly discharge the chips generated during the cutting process, prevent the chips from accumulating in the cutting area, and thus avoid affecting the continuity and stability of the cutting process.

[0029] Preferably, the surface of the blade body 1 is coated with a titanium oxide coating.

[0030] This includes a center hole 6, which is coaxial with the axis of the tool body 1 and extends through both the tool body 1 and the tool holder 2. The center hole 6 primarily helps to remove metal chips generated during the cutting process, preventing blockages, ensuring smooth drilling, and improving tool stability.

[0031] Further optimization involves providing a quick-connect plug at the tail of the tool holder 2.

[0032] This utility model provides a novel design for a highly stable and heat-dissipating dental drill that overcomes the shortcomings of existing technologies. It improves the stability and heat dissipation of the dental drill, enabling doctors to complete surgeries steadily and quickly. It has good application prospects and is worth promoting.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
