[0033] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 As shown, in one embodiment, a bone drilling system is provided, including a bone drilling device 10 and a host (not shown). Thus, the host and the bone drilling device 10 are connected to each other by communication and signal interaction, so as to control a series of operations such as starting and drilling the bone drilling device 10.

[0035] The host may be any existing device capable of signal processing and output.

[0036] It should be noted that the communication connection can be achieved through a wired connection such as a data cable, or through a wireless connection such as Bluetooth transmission, WIFI, NFC, etc.

[0037] like Figure 1 As shown, in one embodiment, a bone drilling device 10 is provided, including a drill bit identification structure 100 , a drill bit 200 and a rotation driving mechanism 300 .

[0038] like Figure 1 and Figure 2As shown, the drill bit 200 has a mounting end 210 and an identified element 211 which is arranged on the mounting end 210 by means of embedding or clamping. The mounting end 210 can be rod-shaped, and the mounting end 210 can be inserted into the drill bit identification structure 100, so that the identified element 211 is recognized by the drill bit identification structure 100 for sensing and matching, and then the drill bit identification structure 100 outputs an identification signal to the host, and then the host makes a judgment based on the identification signal and outputs a corresponding operation instruction.

[0039] like Figure 3 As shown, the rotary drive mechanism 300 can be connected to the mounting end 210 by transmission, so that the drill bit 200 is driven to rotate as a whole by the rotary drive mechanism 300. In this way, after the mounting end 210 is inserted into the drill bit identification structure 100, the rotary drive mechanism 300 and the mounting end 210 are connected by sleeve or plug, and the rotary drive mechanism 300 drives the mounting end 210 to rotate so that the entire drill bit 200 rotates to perform the drilling operation. In addition, the host is connected to the rotary drive mechanism 300 by communication, and the host controls the start and stop of the rotary drive mechanism 300 after judging the identification signal.

[0040] The rotary drive mechanism 300 may include components such as a motor and a planetary reducer, and can drive the drill bit 200 to rotate.

[0041] It should be noted that the bone drilling device 10 may also include components such as a handle and a drill bit mounting structure, which are not described in detail here because they may belong to the prior art.

[0042] In one embodiment, a drill bit identification structure 100 is provided, including a mounting assembly (not labeled) and an identification element (not shown).

[0043] like Figure 3 and Figure 4 As shown, the mounting assembly is provided with an inserting channel 110 for inserting the drill bit 200 and a mounting cavity 120 located in the circumference of the inserting channel 110 .

[0044] Specifically, the mounting assembly is provided with a plug-in channel 110 extending along the axial direction of the drill bit 200 , and the drill bit 200 and the drill bit identification structure 100 are assembled and connected by inserting the mounting end 210 into the plug-in channel 110 and plugging and mating with the plug-in channel 110 .

[0045] The identification element is arranged in the installation cavity 120 by means of clamping, bonding, etc., and the identification element can cooperate with the drill bit 200 by induction to output an identification signal to the outside.

[0046] Specifically, when replacing the drill bit 200, after the mounting end 210 of the drill bit 200 is inserted into the plug-in channel 110 and plugged into place with the plug-in channel 110, the identification element can be arranged relative to the identified element 211 on the mounting end 210 and sensed and matched, so that the identification element generates an identification signal, and the identification signal is output to the host in combination with the communication connection between the identification element and the host. When the host receives the identification signal, it can be determined that the replaced drill bit 200 is in a matching state, that is, the replaced drill bit 200 not only matches the application scenario, but also matches the fuselage 11. At this time, the host can control the rotation drive mechanism 300 to start and drive the drill bit 200 to rotate to perform bone drilling and other operations normally. If, after the mounting end 210 of the drill bit 200 is inserted into the insertion channel 110, the identification element and the identified element 211 on the mounting end 210 are arranged relative to each other and cannot sense and cooperate, so that the identification element cannot generate an identification signal, and the host cannot receive the identification signal, it can be determined that the replaced drill bit 200 is in a mismatched state, that is, the replaced drill bit 200 cannot be matched with the application scenario and / or cannot be matched with the fuselage 11. At this time, the rotary drive mechanism 300 is in a stopped state and the drill bit 200 cannot rotate, thereby reminding the operator that the replaced drill bit 200 does not match.

[0047] The induction coordination between the identification element and the identified element 211 can be achieved by electromagnetic induction. For example, the identification element and the identified element 211 can be electromagnetic induction between an identification chip and an identification coil. It can also be achieved by near field communication, as long as it can generate an identification signal.

[0048] like Figure 3 and Figure 4 As shown, optionally, the mounting assembly includes a first mounting sleeve 130 and a second mounting sleeve 140. The first mounting sleeve 130 is disposed in the second mounting sleeve 140 and is surrounded by the second mounting sleeve 140 to form a mounting cavity 120. In this way, the identification element can be assembled and connected with the first mounting sleeve 130 first, and then the first mounting sleeve 130 can be encapsulated in the second mounting sleeve 140, so that the identification element is encapsulated in the mounting cavity 120, which reduces the difficulty of assembly. In addition, the first mounting sleeve 130 is connected to the second mounting sleeve 140 to form a plug-in channel 110. In this way, the mounting end 210 of the drill bit 200 passes through the first mounting sleeve 130 and the second mounting sleeve 140 to achieve plug-in matching with the plug-in channel 110 until it is plugged in place, so that the identified element 211 is inductively matched with the identification element.

[0049] like Figure 3 and Figure 4As shown, further, the inlet end of the first mounting sleeve 130 is provided with a first extension portion 131 extending radially outward, that is, the first extension portion 131 extends from the inlet end of the first mounting sleeve 130 along the radial direction of the first mounting sleeve 130 toward the outside of the first mounting sleeve 130. The inlet end of the second mounting sleeve 140 is provided with a second extension portion 141 extending radially outward, that is, the second extension portion 141 extends from the inlet end of the second mounting sleeve 140 along the radial direction of the second mounting sleeve 140 toward the inside of the second mounting sleeve 140. In addition, the second extension portion 141 is arranged opposite to the first extension portion 131, that is, the projections of the second extension portion 141 and the first extension portion 131 in the axial direction of the insertion channel 110 overlap each other. At the same time, the drill bit identification structure 100 also includes a first seal 150, which is used to make the first extension portion 131 and the second extension portion 141 seal and cooperate. In this way, the first seal 150 can be arranged between the first extension part 131 and the second extension part 141, so as to enhance the sealing performance between the first extension part 131 and the second extension part 141, and prevent water in the plug-in channel 110 from entering the installation cavity 120 from the gap between the first extension part 131 and the second extension part 141 to interfere with or corrode the identification element, thereby ensuring stable and reliable operation of the identification element.

[0050] The first extension portion 131 and the second extension portion 141 may both be annular structures such as flanges, so that the first extension portion 131 and the second extension portion 141 are assembled face to face, and combined with the sealing of the first sealing member 150, better sealing performance is achieved.

[0051] The first sealing member 150 may be in the form of a sealing ring or a sealing gasket, and may be made of elastic materials such as rubber to ensure sealing performance.

[0052] like Figure 3 and Figure 4As shown, further, the end of the first installation sleeve 130 away from the inlet end of the first installation sleeve 130 is provided with a third extension portion 132 and a fourth extension portion 133 connected to each other, that is, the fourth extension portion 133 is connected to the first installation sleeve 130 through the third extension portion 132. Among them, the third extension portion 132 extends radially outward, that is, the third extension portion 132 extends toward the outside of the first installation sleeve 130 along the radial direction of the first installation sleeve 130. The fourth extension portion 133 extends axially away from the first extension portion 131, that is, the fourth extension portion 133 extends in the axial direction of the insertion channel 110 in a direction away from the first extension portion 131. In this way, combined with the parallel arrangement of the first extension portion 131 and the third extension portion 132, a corresponding groove structure can be formed on the outside of the first installation sleeve 130, and the identification element can be installed in the groove structure. When the first installation sleeve 130 is completely encapsulated in the second installation sleeve 140, the groove structure can be closed to form the installation cavity 120. At the same time, the drill bit identification structure 100 further includes a second sealing member 160, which is used to seal the inner side wall of the second mounting sleeve 140 with the fourth extension portion 133. In this way, the second sealing member 160 can be disposed between the inner side wall of the second mounting sleeve 140 and the fourth extension portion 133, thereby enhancing the sealing performance between the inner side wall of the second mounting sleeve 140 and the fourth extension portion 133, preventing water in the plug-in channel 110 from entering the mounting cavity 120 from the gap between the inner side wall of the second mounting sleeve 140 and the fourth extension portion 133 to interfere with or corrode the identification element, thereby ensuring stable and reliable operation of the identification element.

[0053] Among them, the third extension part 132 and the fourth extension part 133 can both be annular structures such as flanges, so that the fourth extension part 133 and the inner wall of the second mounting sleeve 140 are assembled face to face, combined with the sealing of the second sealing member 160, to achieve better sealing performance.

[0054] The second sealing member 160 may be in the form of a sealing ring or a sealing gasket, and may be made of elastic materials such as rubber to ensure sealing performance.

[0055] The first extension portion 131 , the first installation sleeve 130 , the third extension portion 132 and the fourth extension portion 133 may be manufactured in an integrated manner, which can save processing costs and simplify the assembly structure.

[0056] The second extension portion 141 and the first installation sleeve 130 can be manufactured in an integrally formed manner, which can save processing costs and simplify the assembly structure.

[0057] like Figure 3 and Figure 4As shown, in addition, the second extension portion 141 is in conflict with the first extension portion 131, and the third extension portion 132 is in conflict with the rotation drive mechanism 300. In this way, the two ends of the first installation sleeve 130 are in conflict with the second installation sleeve 140 and the rotation drive mechanism 300 respectively, so that the first installation sleeve 130 can be stably and reliably installed in the second installation sleeve 140 to avoid axial movement.

[0058] like Figure 3 and Figure 4 As shown, specifically, the third extension portion 132 is in abutment with the positioning bearing 310 of the rotary drive mechanism 300 .

[0059] like Figure 5 As shown, in addition, the second mounting sleeve 140 is further provided with a lead hole 142 communicating with the mounting cavity 120. Thus, the lead wire can be inserted into the mounting cavity 120 through the lead hole 142 to be electrically connected to the identification element, and then the lead wire can be used to realize communication connection between the host and the identification element.

[0060] Optionally, the lead hole 142 is disposed at a side away from the second extension portion 141 , which can shorten the distance to the host.

[0061] It should be noted that a wire guide channel communicating with the wire guide hole 142 may be provided on the body 11 of the bone drilling device 10 to facilitate wire routing and connection with the host.

[0062] Furthermore, the drill bit identification structure 100 further includes a blocking layer (not shown), which is used to block the gap between the side wall of the lead hole 142 and the lead. In this way, the blocking layer is used to block the gap to prevent external water from entering the installation cavity 120 through the gap to interfere with or corrode the identification element, thereby ensuring stable and reliable operation of the identification element.

[0063] The sealing layer may be a filling material such as a sealant.

[0064] like Figure 3 and Figure 4 As shown, in one embodiment, the drill bit identification structure 100 further includes a third sealing member 170, which is sleeved on the outer side wall of the second mounting sleeve 140 so that the second mounting sleeve 140 and the fuselage 11 are sealed. In this way, the third sealing member 170 can be arranged between the outer side wall of the second mounting sleeve 140 and the fuselage 11, thereby enhancing the sealing performance between the outer side wall of the second mounting sleeve 140 and the fuselage 11, and preventing external water from entering the interior of the fuselage 11 from the gap between the outer side wall of the second mounting sleeve 140 and the fuselage 11 to interfere with or erode the components such as the rotation drive mechanism 300.

[0065] The third sealing member 170 may be in the form of a sealing ring or a sealing gasket, and may be made of elastic materials such as rubber to ensure sealing performance.

[0066] It should be noted that "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; it can also be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be manufactured independently and then combined with the "other parts of the component" into a whole.

[0069] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0070] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
