Description

Technical Field

[0001] This invention relates to a cutter, and more particularly to a dental bone cutter. Background Technology

[0002] A bone cutter is a medical device commonly used in oral surgery. It is used to cut and trim bone tissue during oral procedures to facilitate dental or alveolar surgery. This device is typically used by oral surgeons or dentists in surgeries requiring bone reshaping. Extreme care and precision are required during its use to ensure patient safety and surgical success.

[0003] Common bone cutters consist of a handle, a blade, and other components, and are used in conjunction with a hammer. The hammer is used to strike the bone, while the blade effectively cuts and reshapes the bone tissue. Using this type of bone cutter requires a high level of skill from the dentist in wielding the hammer. Failure to strike at the correct angle can lead to inaccurate cuts, missing the target, or even striking the patient's face, causing injury.

[0004] To address the above issues, we provide a dental bone cutter to meet the needs of oral surgery. Summary of the Invention

[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0038] This application provides a bone cutter.

[0039] Example 1, as Figure 1-5 As shown.

[0040] A bone cutter includes a handle 1 for a doctor to hold during use.

[0041] The handle 1 is a bendable structure, which makes it easy to adjust the position of the handle 1, making it easier for doctors to hold and for the hammer to strike at the correct angle.

[0042] The handle 1 includes an upper handle 11 and a lower handle 12. The bottom end of the upper handle 11 is rotatably connected to the top end of the lower handle 12. The bottom end of the lower handle 12 extends downward to form a tapered rod head 13, and an extension rod 14 is provided at the bottom end of the rod head 13. In use, the doctor holds the lower handle 12, while the upper handle 11 extends to the outside of the patient's mouth. By adjusting the angle between the upper handle 11 and the lower handle 12, it is easier for the doctor to use a hammer to strike, and it can also avoid contact with the patient's tissues, thus avoiding damage to surrounding tissues during the striking process.

[0043] Furthermore, the bent portion of the handle 1 is covered with a connecting sleeve 15, which is a flexible structure, with both ends sealed to the two ends of the bent portion of the handle 1. This prevents patient tissue from entering the handle 1 during surgery.

[0044] A rod rotation assembly 16 is installed between the upper handle 11 and the lower handle 12, and the upper handle 11 and the lower handle 12 are rotatably connected through the rod rotation assembly 16. This allows the angle between the upper handle 11 and the lower handle 12 to be changed.

[0045] The rotating rod assembly 16 includes a rotating bracket 161 and a rotating rod 162. The rotating bracket 161 is mounted on the top of the lower handle 12, and the rotating rod 162 is rotatably connected to both sides of the rotating bracket 161. The other end of the rotating rod 162 is fixedly connected to the lower end of the upper handle 11. The lower handle 12 is rotatably connected to the upper handle 11 through the rotating bracket 161, the rotating rod 162, and the rotating rod 162, thereby changing the angle between them. This allows doctors to tap at a more convenient angle, reducing the reliance on the doctor's skill level and making it easier for doctors to operate.

[0046] Furthermore, a rotation control assembly 17 is installed between the upper handle and the lower handle to control the rotation between the upper handle and the lower handle and adjust the angle between the upper handle and the lower handle.

[0047] The rotation control assembly 17 includes a connecting plate 171, a linkage rod 172, a rotating box 173, a control rod 174, a handwheel 175, and a gear 176. The connecting plate 171 is provided at the lower part of the upper handle and the upper part of the lower handle. The outer ends of the connecting plates 171 are rotatably connected to the linkage rods 172. The control rod 174 is rotatably connected through the middle of the rotating box 173. One end of the control rod 174 extends outside the rotating box 173 and is equipped with the handwheel 175. The gear 176 is mounted on the control rod 174. The two linkage rods 172 extend into the rotating box 173 and mesh with the gear 176 for transmission. In use, rotating the handwheel 175 causes the two linkage rods 172 to move towards or away from each other through the meshing transmission between the gear 176 and the two linkage rods 172, thereby changing the distance between the two connecting plates 171 and ultimately changing the angle between the upper handle and the lower handle.

[0048] Furthermore, the linkage rod 172 is slidably connected to the rotating box 173 to prevent the linkage rod 172 from wobbling during movement.

[0049] It also includes a transmission component 2, which is installed inside the handle 1 and extends through the handle 1. Striking the top of the transmission component 2 is done in place of striking the top of the handle 1.

[0050] The transmission assembly 2 includes a transmission rod 21 and a striking plate 22. The transmission rod 21 is slidably connected through the handle 1. The striking plate 22 is located at the top of the transmission rod 21, and the blade 3 is installed at the bottom of the transmission rod 21. In use, the doctor strikes the striking plate 22 with a hammer, and the blade 3 cuts bone tissue.

[0051] The transmission rod 21 includes an upper transmission rod 211 and a lower transmission rod 212. The upper transmission rod 211 is slidably connected through the upper handle 11, and the lower transmission rod 212 is slidably connected through the lower handle 12 during water spraying. The lower end of the upper handle 11 and the upper end of the lower handle 12 are rotatably connected. This allows the transmission assembly 2 to rotate synchronously with the upper handle 11 and the lower handle 12.

[0052] The upper transmission rod 211 includes several sliding blocks 2111, several sub-rods 2112, a striking rod 2113, and a push-pull rod 2114. Several sliding blocks 2111 are slidably connected inside the upper handle rod 11. A sub-rod 2112 is rotatably connected between two adjacent sliding blocks 2111. The striking rod 2113 is located at the top of the uppermost sliding block 2111, and a striking plate is located at the top of the striking rod 2113. The push-pull rod 2114 is located at the bottom of the lowermost sliding block 2111, and the bottom end of the push-pull rod 2114 is rotatably connected to the top end of the lower transmission rod 212. This allows for smooth transmission of the impact from the hammer strike, driving the blade 3 to cut bone tissue.

[0053] Furthermore, the bottom end of the lower transmission rod 212 is provided with an anti-collision groove to prevent the push-pull rod 2114 from interfering with the movement and thus preventing the transmission of impact.

[0054] A braking component is provided inside the lower handle 12 to control the movement of the transmission component 2. When the braking component is activated, the transmission component 2 will be unable to move up or down.

[0055] It also includes a blade 3, which is installed at the bottom of the transmission assembly 2 and is used to cut bone tissue. Different blades 3 are installed according to different needs.

[0056] Furthermore, the blade 3 has an expandable structure, which makes it easy to adjust the blade 3 according to the needs of the surgery.

[0057] The blade 3 includes a main blade body 31 and a side blade 32. Connecting grooves are provided on both sides of the main blade body 31, and a connecting shaft is provided on one side of the side blade 32. The connecting shaft is detachably inserted into the connecting groove. The side blade 32 increases the cutting edge length of the blade 3, thereby enabling a wider range of bone tissue cutting.

[0058] Furthermore, the blade 3 is rotatably connected to the transmission assembly 2. This allows for adjustment of the angle of the blade 3 to cut bone tissue.

[0059] A blade rotation assembly 33 is installed between the blade 3 and the transmission assembly 2, and the blade 3 and the blade body are rotatably connected through the blade rotation assembly 33. This allows for adjustment of the angle of the blade 3.

[0060] The blade rotation assembly 33 includes a rotating lug 331, a rotating shaft 332, and a controller 333. The rotating lug 331 is mounted on the bottom of the assembly, and the rotating shaft 332 is rotatably connected to the inner side of the lug 331. The blade 3 is mounted on the rotating shaft 332. An inward groove is formed on the outer side of the lug 331, and one side of the rotating shaft 332 extends into the inward groove. The controller 333 is installed in the inward groove, and the controller 333 controls the rotation of the rotating shaft 332. Preferably, the controller 333 is a micro motor, which drives the rotating shaft 332 to rotate, thereby adjusting the angle of the blade 3.

[0061] When using this invention:

[0062] Adjust the angle of the blade and the angle between the upper and lower handles according to the patient's surgical condition. After adjustment, the doctor holds the lower handle, aligns the blade with the bone tissue to be cut, and then strikes the striking plate with a hammer.
