[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] With reference to FIGS. 1-2, a precisely adjustable drill bit comprises a connecting sleeve 4, one end of the connecting sleeve 4 is threadedly connected with an adjusting member 5, and a locking block 6 is clamped on the end of the adjusting member 5 away from the connecting sleeve 4. In use, the connecting sleeve 4, the adjusting member 5 and the drill bit rod 1 adopt a detachable design, so that the parts can be conveniently separated for cleaning. This design facilitates the doctor and the surgical team to thoroughly clean and disinfect the drill bit after the operation, ensuring the hygiene and safety of the instrument. At the same time, the detachable design also facilitates the maintenance and maintenance of the instrument, prolonging the service life of the drill bit. This improvement brings convenience to the follow-up processing of the operation and the management of the medical instrument, ensuring the safety of the patient and the work efficiency of the doctor.

[0022] The drill bit rod 1 penetrates the locking block 6, the adjusting member 5 and the connecting sleeve 4 at one time, and one end of the drill bit rod 1 extends out of the connecting sleeve 4. Through the connecting mode of the drill bit rod 1, the drill bit rod 1 can be disassembled by removing the pin, so that the drill bit rod 1 can be quickly replaced without additional complex steps or tools. This facilitates the doctor to select drill bits of different specifications, greatly improves the operation efficiency, and also reduces the interruption and delay caused by unexpected drill bit breakage during the operation.

[0023] The adjusting member 5 is fixedly connected with the drill bit rod 1 by a pin, and the drill bit rod 1 adjusts the length of the end extending out of the connecting sleeve 4 by rotating the adjusting member 5. The adjusting member 5 comprises a first threaded end 51 threadedly connected with the connecting sleeve 4 and a fixed segment 52 integrally connected with the first threaded end 51, and a plurality of fixed teeth are fixedly connected on the end face of the fixed segment 52 close to the locking block 6. When adjusting the length of the drill bit rod 1, the adjusting member 5 is rotated at this time to make the adjusting member 5 extend out of or retract into the connecting sleeve 4, thereby driving the drill bit rod 1 to extend out of or retract into the connecting sleeve 4, so as to adjust the length of the drill bit rod 1. The doctor can easily and accurately adjust the length of the drill bit according to the actual operation requirement, ensuring the accuracy and safety of the operation.

[0024] When the length of the drill bit rod 1 extending out of the connecting sleeve 4 is determined, the drill bit rod 1 is locked by the locking block 6 at this time, so that the drill bit rod 1 does not displace.

[0025] Further, the connecting sleeve 4 includes a straight rod section 42 and a threaded section 41 integrally communicated with the straight rod section 42, both of which are tubular structures with hollow interiors, wherein the inner wall of the threaded section 41 is provided with threads, and the threaded section 41 is threadedly connected with the adjusting member 5; the straight rod section 42 has a spring placed in the end away from the threaded section 41. The connecting sleeve 4 is provided with a scale line at the position of the limiting groove, and through the design of the scale line, the doctor can conveniently observe the length of the drill bit extended, ensure accurate adjustment, and improve the accuracy and safety of the operation.

[0026] Further, the drill bit rod 1 includes an extension rod section and a drill bit section integrally connected with the extension rod section, the end of the extension rod section away from the drill bit section extends out of the locking block 6 and is fixedly connected with a handle 7, and the end of the handle 7 away from the locking block 6 is a rotatable handle cap, which enhances the confidence and operation comfort of the doctor. The drill bit of the drill bit section is designed as a double-line spiral blade edge, which can effectively improve the drilling speed, make the operation process more rapid and efficient, and help to reduce the operation time and the discomfort of the patient. The drill bit rod 1 is fixedly connected with a limiting pin 3, and the connecting sleeve 4 is provided with a limiting groove at the position of the limiting pin 3, which matches the limiting pin 3. Through the design of the limiting pin 3, the drill bit can be effectively ensured not to accidentally fall off during the operation, thereby improving the safety of the operation. This improvement enables the doctor to focus more on the operation without worrying about the stability of the drill bit, which helps to reduce anxiety and uncertainty in the operation, thereby improving the success rate and efficiency of the operation. The spring is sleeved on the drill bit section, which makes the drill bit section have good adjustment feel and telescopic performance during use. This design can effectively reduce the discomfort in the operation, making the doctor more easily control the operation of the drill bit, thereby improving the accuracy and safety of the operation. At the same time, the spring connection can also reduce the fatigue of the doctor's hands, making the operation more smooth and comfortable.

[0027] Further, the end face of the locking block 6 close to the adjusting member 5 is provided with a plurality of teeth, which match with the fixed teeth. When the doctor adjusts the drill bit rod 1 to the required length, the locking block 6 and the adjusting member 5 are matched through the teeth and the fixed teeth, the drill bit rod 1 is fixed, the length of the drill bit in the operation is effectively locked, and the safety of the operation is ensured. The locking block 6 is installed with an elastic button, and the locking block 6 is fixedly connected with the drill bit rod 1 by pressing the elastic button. When the length of the drill bit rod 1 needs to be adjusted, the elastic button is popped out, the locking block 6 is separated from the adjusting member 5, and then the length of the drill bit rod 1 is adjusted by rotating the adjusting member 5. Through the clamping of the locking block 6 and the adjusting member 5, the drill bit rod 1 is locked by the horizontal displacement of the locking block 6.

[0028] In use, the doctor needs to match the appropriate size according to the selected screw specification to ensure the accuracy and matching of the drill hole size. When assembling the drill bit, the doctor should operate carefully to ensure that the spring is correctly fitted on the drill bit and placed in the connecting sleeve 4, then tighten the adjusting piece 5 to ensure that each step is firm and reliable. After installation, the doctor can accurately adjust the length of the drill bit rod 1 through the adjusting piece 5 to ensure that it matches the patient's tissue and make fine adjustments as needed to ensure the accuracy and safety of the operation. After adjusting the length, the drill bit rod 1 needs to be locked, the locking block 6 is connected with the adjusting piece 5, and the elastic button is fixed with the drill bit rod 1 to ensure the length of the drill bit rod 1 is fixed to ensure safety during the operation. During the operation, the doctor should focus on the drilling operation to ensure the accuracy and smoothness of the operation, avoid external interference and operation errors, and improve the success rate of the operation and the safety of the patient. By optimizing the implementation process, the doctor can more smoothly complete the operation, reduce operation errors and unnecessary fatigue, thereby improving the efficiency and quality of the operation and ensuring the safety of the patient and the comfort of the doctor's operation.

[0029] In summary, the double-line spiral design of the drill bit edge and the scale line observation function in this application greatly improve the accuracy and controllability of the operation, allowing the doctor to more accurately cut the tissue and monitor the operation depth in real time, thereby reducing the risk of surgery and improving the success rate of the operation. The adjustable length design and spring-connected drill bit rod allow the doctor to more easily master the operation, reducing hand fatigue and further improving the efficiency of the operation. At the same time, the limit pin design ensures the safety and stability of the instrument, reduces the occurrence of accidents, and enhances the confidence and comfort of the doctor. The detachable design of the drill bit simplifies the cleaning and maintenance process, ensuring the hygiene and safety of the surgical instrument. Not only does it improve the accuracy and efficiency of the operation, but it also significantly reduces the risk of surgery, providing patients with a safer and more accurate surgical experience and doctors with a more reliable and convenient operating tool, with a wide market application prospect and medical value.
