[0035] Existing surgical milling cutters typically lack recognition capabilities. During surgery, especially when rapid cutter changes or adjustments to surgical strategies are required, surgeons must frequently adjust the cutter's operating parameters based on experience, leading to reduced surgical efficiency.

[0036] This utility model proposes a medical milling tool.

[0037] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the medical milling tool 100 includes:

[0038] The blade head 11 is provided with a cutting edge extending along its axial direction;

[0039] The tool holder 12 is connected to the rear end of the tool head 11, and the tool holder 12 extends rearward along the axial direction of the tool head 11. The outer wall of the tool holder 12 is provided with a recess to form a receiving cavity.

[0040] Electronic tag 2, disposed within the accommodating cavity and with a gap between it and the cavity wall, stores information about the cutting tool 1 of the medical milling tool 100; and

[0041] Positioning sleeve 3 is fitted around the outer periphery of the tool holder 12 and fixes the electronic tag 2 inside the accommodating cavity.

[0042] The technical solution of this utility model divides the blade 1 into a blade head 11 and a blade holder 12. A recess is provided on the outer wall of the blade holder 12, concave towards the interior of the blade holder 12 to form a receiving cavity. An electronic tag 2 is intermittently disposed within the receiving cavity to ensure that the electronic tag 2 does not contact the cavity wall, preventing the blade 1 from interfering with the signal transmission of the electronic tag 2. By placing a positioning sleeve 3 on the blade holder 12 near the electronic tag 2, the electronic tag 2 is effectively fixed within the receiving cavity and additionally protected, reducing wear on the electronic tag 2 during blade cleaning and disinfection. The information of the blade 1 stored on the electronic tag 2 includes, but is not limited to, model, expiration date, disinfection record, and usage parameters. This information can be quickly obtained through a wireless reading device, allowing for rapid matching of parameters such as blade 1 model, blade 1 rotation speed, and running time at the host end, eliminating the need for manual input, improving surgical efficiency, and preventing misuse of the blade 1.

[0043] Specifically, the type of electronic tag 2 is not specifically limited; for example, it can be an RFID tag or an NFC tag, as long as the identification information set on it can be transmitted to the reading device via a signal. The electronic tag 2 enables short-range communication, allowing doctors to quickly set the operating parameters of the surgical instrument 1, helping to prevent misuse of the instrument 1 during surgery, thereby improving surgical safety and efficiency. In this embodiment, a positioning hole can be provided on the side of the positioning sleeve 3 facing the accommodating cavity. The electronic tag 2 is installed in the positioning hole, and there is a certain gap between the electronic tag 2 and the cavity wall to prevent the electronic tag 2 from contacting the metal blade holder 12, thus preventing the surgical instrument 1 from interfering with the electrical signal emitted by the electronic tag 2 and affecting the external reading device's reading of the information of the surgical instrument 1. It is worth noting that the length of the positioning sleeve 3 is not specifically limited, as long as it is fitted into the accommodating cavity and serves to fix the electronic tag 2.

[0044] In the embodiments of this utility model, please refer to Figure 2The medical milling cutter 100 also includes a label holder 4, which is fixedly embedded in the receiving cavity. The electronic tag 2 is mounted on the label holder 4 with a gap between it and the cavity wall. By mounting the electronic tag 2 on the label holder 4 and ensuring a gap between it and the cavity wall, direct contact between the electronic tag 2 and the cavity wall can be prevented, reducing tag damage caused by friction or collision. It should be noted that the label holder 4 can be a bracket whose shape matches the inside of the receiving cavity, and the label holder 4 has multiple protruding fixing points for holding the edge of the electronic tag 2. Furthermore, the label holder 4 can also be provided with an elastic clamping structure, such as a spring clip. When the electronic tag 2 is placed in the label holder 4, the spring clip can automatically clamp the electronic tag 2 to ensure its firm fixation. In specific implementation, the label holder 4 can be pre-fixed in the receiving cavity by means of adhesive bonding, etc., so that the positioning sleeve 3 can be fitted on the outside of the cutter head 12.

[0045] In the embodiments of this utility model, please refer to Figure 2 The tag holder 4 has a mounting groove, and the electronic tag 2 is fixedly installed in the mounting groove with a gap between it and the cavity wall. In this embodiment, the tag holder 4 has a mounting groove for fixing the electronic tag 2, and the groove opening faces the positioning sleeve 3. In this way, the groove wall forms a barrier between the electronic tag 2 and the cavity wall, effectively preventing direct contact between the electronic tag 2 and the cavity, thereby preventing the tool 1 from affecting the signal transmission of the electronic tag 2. Furthermore, a sealing ring can also be provided between the tag holder 4 and the positioning sleeve 3 to protect the electronic tag 2 from liquid corrosion.

[0046] In embodiments of this invention, the positioning sleeve 3 is interference-fitted and / or welded to the tool holder 12. That is, the connection between the positioning sleeve 3 and the tool holder 12 can be an interference fit, with the inner diameter of the positioning sleeve 3 slightly smaller than the outer diameter of the tool holder 12. The positioning sleeve 3 is pressed onto the tool holder 12 by pressure to form an interference fit. This fit provides strong fastening force, preventing the positioning sleeve 3 from rotating or moving on the tool holder 12. Alternatively, the connection between the positioning sleeve 3 and the tool holder 12 can be a pure welding method. Welding provides a sealed connection and high connection strength, improving the stability of the overall structure. Of course, to facilitate the fitting of the positioning sleeve 3 onto the tool holder 12, the inner diameter of the positioning sleeve 3 can be set slightly smaller than the outer diameter of the tool holder 12, using a combination of slight interference fit and welding. Local welding is performed at the connection point between the positioning sleeve 3 and the tool holder 12 to further enhance the stability of the connection. The welding point can be designed in a specific area of ​​the positioning sleeve 3, such as the edge or a specific fixing point, to ensure that the welding does not affect the function of the tool 1.

[0047] In the embodiments of this utility model, please refer to Figure 3The positioning sleeve 3 has a perforated hole 31, through which at least part of the tag holder 4 is exposed. The perforated hole 31 corresponds to the electronic tag 2, preventing the positioning sleeve 3 from obstructing the signal transmission of the electronic tag 2. By providing the perforated hole 31 on the positioning sleeve 3, the signal of the electronic tag 2 can be directly transmitted, ensuring that the signal transmission of the electronic tag 2 is not obstructed, avoiding signal attenuation caused by obstruction, and improving reading accuracy. The perforated hole 31 can be circular, rectangular, or any shape suitable for the electronic tag 2 to maximize signal transmission efficiency. Additionally, the edges of the perforated hole 31 can be chamfered or rounded to reduce friction and wear, creating a gap between the electronic tag 2 and the perforated hole 31, ensuring that the electronic tag 2 does not directly contact the positioning sleeve 3.

[0048] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The medical milling cutter 100 also includes a gasket 5, which is disposed within the receiving cavity. The electronic tag 2 is disposed between the gasket 5 and the positioning sleeve 3. The gasket 5 reduces direct contact between the electronic tag 2 and the positioning sleeve 3, reducing wear and extending the service life of the electronic tag 2. The gasket 5 can be fixed in the receiving cavity by adhesive, snap-fit, or embedded design to ensure that it will not move or fall off during the use of the cutter 1. The gasket 5 can be designed as round, square, or other shapes to adapt to the internal structure of the receiving cavity and the size of the electronic tag 2.

[0049] In this embodiment of the invention, the gasket 5 is made of an elastic material, such as silicone, thermoplastic elastomer, or polyurethane. When the positioning sleeve 3 is fitted onto the outer periphery of the blade holder 12, the gasket 5 can be compressed to produce a certain deformation, thereby tightly clamping the electronic tag 2 between the positioning sleeve 3 and the gasket 5, improving the fixing strength of the electronic tag 2. The elastic material gasket 5 can also provide cushioning protection for the electronic tag 2, reducing damage to the electronic tag 2 caused by vibration or impact during the use of the blade 1.

[0050] In this embodiment of the invention, the positioning sleeve 3 is made of heat-shrinkable material, such as polyethylene, polyester, or polyolefin. The positioning sleeve 3 is heat-shrinkably bonded to the outer wall of the blade holder 12 to fix the electronic tag 2. Specifically, the positioning sleeve 3 is made of polyethylene tubing. It is placed on the outside of the blade holder 12 and then heated. The polyethylene tubing shrinks after heating, and the shrinkage force of the heat-shrinkable material can provide a stable clamping force for the electronic tag 2, reducing the displacement of the electronic tag 2 caused by vibration or impact during the use and cleaning of the blade 1, so as to firmly fix the electronic tag 2 in the accommodating cavity.

[0051] In the embodiments of this utility model, please refer to Figure 5The outer wall of the tool holder 12 is also provided with a positioning groove, which communicates with the receiving cavity. The gasket 5 is placed inside the receiving cavity, and the positioning sleeve 3 is fixedly embedded in the positioning groove, so that the electronic tag 2 is clamped between the gasket 5 and the positioning sleeve 3. By providing an interconnected positioning groove and receiving cavity on the outer wall of the tool holder 12, the electronic tag 2 can be fixed inside the receiving cavity first, and then the positioning sleeve 3 can be placed on the outside. The positioning groove provides a precise position for the placement of the positioning sleeve 3, guiding the installation of the positioning sleeve 3 and simplifying the installation and maintenance process of the electronic tag 2. It should be noted that the length of the positioning groove should be slightly larger than the length of the receiving cavity to ensure that the positioning sleeve 3 can completely cover the gasket 5.

[0052] This utility model also proposes a medical milling device capable of reading tool information. The medical milling device includes a power handle and a medical milling tool 100. The specific structure of the medical milling tool 100 is as described in the above embodiment. The power handle is equipped with an identification component. The identification component is used to read the tool information stored on the electronic tag when the medical milling tool 100 is connected to the power handle. In specific implementation, the electronic tag can be read by radio frequency identification.

[0053] Since this medical milling device capable of reading tool information adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. The power handle can be designed as a handheld device, with a built-in motor and transmission system, powered by cable or wirelessly. The power handle is equipped with a switch and adjustment buttons for controlling the speed and direction of the tool 1. The front end of the power handle is designed with a connection interface that matches the tail end of the medical milling tool 100, ensuring that the tool 1 can be quickly and accurately installed on the handle.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
