This prevents the sensor from loosening or even being thrown out under the action of centrifugal force during the rotation of the connecting column, ensuring the identification effect and the stability and reliability of the operation. At the same time, since the mounting groove is located on the circumferential outer wall of the connecting column on the outer casing, the sensor can be better and more accurately identified by the identification component, and it is also convenient to remove the sensor for replacement or maintenance.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an identifiable skull drill bit and skull drill device. Background Technology

[0002] A skull drill typically consists of two parts: a power handle and a skull drill bit. The skull drill bit is connected to the power handle, which drives the drill bit to rotate and perform drilling operations on the skull tissue. Because there are many types of skull drill bits, to avoid mismatches between the drill bit and the power handle, sensors and recognition devices are usually installed in both the drill bit and the power handle. The accurate matching between the drill bit and the power handle is ensured through the sensing and interaction between the sensors and the recognition devices. Since the skull drill bit rotates at high speed during operation, the sensors mounted on it are prone to loosening or even being thrown off under centrifugal force, affecting the recognition effect. Utility Model Content

[0003] Therefore, it is necessary to provide a recognizable skull drill bit and skull drill device to address the problem that the sensing element of the skull drill bit is prone to loosening or even being thrown out under the action of centrifugal force, which affects the recognition effect.

[0004] The technical solution is as follows:

[0005] On the one hand, it provides an identifiable skull drill bit.

[0006] include:

[0007] A drill bit used for drilling skull tissue;

[0008] A connecting post, the front end of which is driven to the rear end of the drill bit, and the rear end of which is used to connect to an external power handle.

[0009] The outer casing is fitted over the drill bit and the connecting post. The front end of the drill bit extends out of the outer casing, and the rear end of the connecting post extends out of the outer casing. The connecting post has a mounting groove on the circumferential outer wall of the portion extending out of the outer casing.

[0010] A mounting base, wherein the mounting base is installed within the mounting groove, and at least a portion of the outer side wall of the mounting base is securely fitted to the inner side wall of the mounting groove; and

[0011] A sensor is disposed within the mounting base, and the sensor records the current identification information of the skull drill bit.

[0012] The technical solution will be further explained below:

[0013] In one embodiment, the connecting post extends from the outer casing and includes a stepped portion near the outer casing and a post portion away from the outer casing, with the mounting groove provided on the circumferential outer wall of the stepped portion.

[0014] In one embodiment, along the axial direction of the connecting column, the mounting base has a first end and a second end opposite to each other, and the mounting groove has a closed end and an open end opposite to each other; the width of the first end is smaller than the width of the second end, the width of the open end is larger than the width of the first end, and the inner sidewall of the open end is fastened to the outer sidewall of the second end.

[0015] In one embodiment, the width of the mounting groove remains consistent along the axial direction of the connecting post; or the width of the mounting groove decreases from the open end to the closed end, and the inner wall of the closed end is fastened to the outer wall of the first end.

[0016] In one embodiment, the mounting base has a mounting surface facing the inner wall of the mounting groove, the mounting surface having a receiving groove, and the sensing element is disposed within the receiving groove.

[0017] In one embodiment, the mounting surface has a bottom surface facing the bottom wall of the mounting groove, and the bottom surface is provided with the receiving groove.

[0018] In one embodiment, the skull drill bit further includes an adhesive layer that fills the space between the sensing element and the inner wall of the receiving groove.

[0019] In one embodiment, the mounting base includes a non-electromagnetic body, and the sensing element is disposed within the non-electromagnetic body.

[0020] In one embodiment, the depth of the mounting groove along the radial direction of the connecting post matches the thickness of the mounting base.

[0021] On the other hand, a skull drill device is provided, including a power handle and the identifiable skull drill bit. The power handle is operatively connected to the connecting column. The power handle is provided with an identification element that senses and cooperates with the sensing element. The identification element is used to read the current skull drill bit's identification information recorded by the sensing element.

[0022] The identifiable skull drill bit and skull drilling device of the above embodiments, after the connecting column and the power handle are connected by transmission, enable the sensor to cooperate with the identification component. When the identified signal indicates that the skull drill bit and the power handle are compatible, the power handle can then operate to transmit power to the skull drill bit to perform operations such as drilling bone. Furthermore, since the sensor is mounted on the mounting base, and at least part of the outer wall of the mounting base is tightly fitted with the inner wall of the mounting groove of the connecting column, the assembly and connection of the sensor, mounting base, and connecting column can be stably and reliably achieved. This prevents the sensor from loosening or even being thrown out under the action of centrifugal force during the rotation of the connecting column, ensuring the identification effect and the stability and reliability of the operation. At the same time, since the mounting groove is located on the circumferential outer wall of the connecting column on the outer casing, the sensor can be better and more accurately identified by the identification component, avoiding signal isolation or interference. Moreover, it facilitates the removal of the sensor for replacement or maintenance. Attached Figure Description

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 2 As shown, in one embodiment, a skull drill device is provided, including an identifiable skull drill bit 10 and a power handle (not shown). The power handle is drive-connected to the skull drill bit 10, thereby transmitting power to the skull drill bit 10 to drive it to rotate at high speed, thus enabling drilling and other operations on bone tissue.

[0032] Optionally, the transmission connection between the power handle and the identifiable skull drill bit 10 can be achieved through a plug-in connection or other means. Since this is existing technology, it will not be elaborated or enumerated here.

[0033] like Figures 1 to 3 As shown, in one embodiment, an identifiable skull drill bit 10 is provided, which includes a drill bit 400, a connecting post 100, a housing 500, a mounting base 200, and a sensing element 300.

[0034] The drill bit 400 is used to drill skull tissue, thereby enabling operations such as drilling holes in the bone tissue.

[0035] Alternatively, the drill head 400 can adopt an existing structure, which will not be described in detail or enumerated here.

[0036] The connecting post 100 can be roughly cylindrical or have a separate or integral structure. The front end of the connecting post 100 is driven to the rear end of the drill head 400, and the rear end of the connecting post 100 is used to connect to an external power handle, so that the power of the power handle can be transmitted to the drill head 400 through the connecting post 100 to drill holes in bone tissue such as the skull.

[0037] The outer casing 500 has a hollow structure, such as a sleeve. The outer casing 500 is fitted over the drill head 400 and the connecting post 100; optionally, both the drill head 400 and the connecting post 100 are partially located within the outer casing 500. Furthermore, the front end of the drill head 400 extends out of the outer casing 500, and the rear end of the connecting post 100 extends out of the outer casing 500, thereby allowing the outer casing 500 to further limit and shield the assembly of the drill head 400 and the connecting post 100. Moreover, the connecting post 100 has a mounting groove 110 on its circumferential outer wall of the portion extending out of the outer casing 500.

[0038] It should be noted that, in this embodiment of the application, the front end refers to the end closer to the drill head 400, and correspondingly, the rear end refers to the end farther away from the drill head 400.

[0039] The mounting base 200 is installed within the mounting groove 110. Furthermore, at least part of the outer side wall of the mounting base 200 is fastened to the inner side wall of the mounting groove 110, thereby achieving a stable and reliable assembly connection between the mounting base 200 and the connecting column 100 and preventing loosening.

[0040] The sensor 300 is disposed within the mounting base 200. The power handle is equipped with an identification element that engages with the sensor 300. Furthermore, the sensor 300 records the identification information of the current skull drill bit, and the identification element is used to read this information. Thus, when the connecting post 100 is connected to the power handle, the sensor 300 engages with the identification element to identify the skull drill bit 10, such as its model number, ensuring that the power handle is compatible with the correct skull drill bit 10. This also guarantees that the power handle can only operate after being compatible with the specific skull drill bit 10 or after meeting preset usage conditions.

[0041] It should be noted that the sensing element 300 and the identification element can be coupled through electromagnetic induction between coils. The sensing element 300 records the identification information of the current skull drill bit 10. During the sensing coupling, the identification information is acquired by the identification element. The identification information includes product model, product code, number of uses and / or batch date, etc., which will not be listed exhaustively here. In specific implementations, the sensing element 300 can be an electronic tag such as a radio frequency sensing chip.

[0042] In the above embodiment of the skull drill bit 10, after the connecting post 100 is connected to the power handle, the sensing element 300 can cooperate with the identification element. When the identified signal indicates that the skull drill bit 10 is compatible with the power handle, the power handle can work to transmit power to the skull drill bit 10 to perform operations such as drilling bones. Furthermore, since the sensing element 300 is mounted on the mounting base 200, and at least part of the outer side wall of the mounting base 200 is tightly fitted with the inner side wall of the mounting groove 110 of the connecting post 100, the assembly and connection of the sensing element 300, the mounting base 200, and the connecting post 100 can be stably and reliably realized. This prevents the sensing element 300 from loosening or even being thrown out under the action of centrifugal force during the rotation of the connecting post 100, ensuring the identification effect and the stability and reliability of the operation. Meanwhile, since the mounting slot 110 is located on the outer circumferential side wall of the connecting post 100 and the housing 500, the sensor 300 can be better and more accurately identified by the identification device, avoiding signal isolation or interference. Moreover, it is convenient to remove the sensor 300 for replacement or maintenance.

[0043] It should be noted that the fastening fit in the embodiments of this application can be achieved by means of interference fit or other methods, as long as it can achieve a stable and reliable assembly connection.

[0044] In one embodiment, the connecting post 100, extending beyond the housing 500, includes a stepped portion 120 near the housing 500 and a columnar portion 130 away from the housing 500. Furthermore, the mounting groove 110 is provided on the circumferential outer wall of the stepped portion 120. This ensures that the mounting groove 110 does not affect the strength of the columnar portion 130, and the stepped portion 120 can be used to position the connecting post 100 and the power handle for assembly, allowing the sensor 300 to better and more accurately engage with the identification element.

[0045] like Figure 1As shown, in one embodiment, along the axial direction of the connecting post 100, the mounting base 200 has a first end 210 and a second end 220, and the mounting groove 110 has a closed end 112 and an open end 111. Furthermore, the width of the first end 210 is smaller than the width of the second end 220, and the width of the open end 111 is larger than the width of the first end 210. Thus, when the first end 210 is inserted into the mounting groove 110 along the axial direction of the connecting post 100, interference or contact is avoided because the width of the open end 111 is greater than the width of the first end 210. This allows the first end 210 to be easily inserted into the mounting groove 110 through the open end 111, reducing assembly difficulty. Furthermore, the inner wall of the open end 111 is tightly fitted with the outer wall of the second end 220. Thus, as the first end 210 is inserted into the mounting groove 110 until the first end 210 reaches the closed end 112, the outer wall of the second end 220 is tightly fitted with the inner wall of the open end 111. This allows the mounting base 200 and the connecting post 100 to achieve a tight and reliable assembly connection, thereby allowing the sensor 300 and the connecting post 100 to achieve a tight and reliable assembly connection. This prevents the sensor 300 from loosening or even being thrown out during the high-speed rotation of the connecting post 100, ensuring the recognition effect and the stability and reliability of the operation.

[0046] It should be noted that the width in the embodiments of this application refers to, as Figure 1 The width in the L direction is shown.

[0047] In one embodiment, the width of the mounting groove 110 remains consistent along the axial direction of the connecting post 100. This consistent width of the mounting groove 110 facilitates its fabrication on the connecting post 100, reducing processing difficulty and saving costs.

[0048] In one embodiment, the width of the mounting groove 110 decreases from the open end 111 to the closed end 112, and the inner wall of the closed end 112 is tightly fitted with the outer wall of the first end 210. Thus, when the first end 210 is inserted into the mounting groove 110 until it reaches the closed end 112, the tight fit between the inner wall of the closed end 112 and the outer wall of the first end 210, combined with the tight fit between the inner wall of the open end 111 and the outer wall of the second end 220, allows for a tighter and more reliable assembly connection between the mounting base 200 and the connecting post 100. This, in turn, allows for a tighter and more reliable assembly connection between the sensor 300 and the connecting post 100, effectively preventing the sensor 300 from loosening or even being ejected during the high-speed rotation of the connecting post 100, ensuring the recognition effect and the stability and reliability of the operation.

[0049] The sensing element 300 is disposed within the mounting base 200, which can be achieved by pre-embedding or by plug-in assembly.

[0050] like Figure 1 As shown, in one embodiment, the mounting base 200 has a mounting surface 231 facing the inner wall of the mounting groove 110, and a receiving groove 240 is provided on the mounting surface 231. The sensing element 300 is disposed in the receiving groove 240. In this way, the sensing element 300 can be installed in the receiving groove 240 first, and then the mounting base 200 can be installed in the mounting groove 110. The inner wall of the mounting groove 110 seals the receiving groove 240, preventing the sensing element 300 from being thrown out of the receiving groove 240, and ensuring a stable and reliable assembly connection between the sensing element 300 and the mounting base 200.

[0051] like Figure 3 As shown, in one embodiment, the mounting surface 231 has a bottom surface 230 facing the bottom wall of the mounting groove 110, and the bottom surface 230 is provided with the receiving groove 240. This facilitates the machining of the receiving groove 240 for mounting the sensing element 300 on the mounting base 200, reducing machining difficulty and saving machining costs.

[0052] In one embodiment, the skull drill bit 10 further includes an adhesive layer (not shown) that fills the space between the sensor 300 and the inner wall of the receiving groove 240. This adhesive layer further bonds and secures the sensor 300 to the mounting base 200, preventing movement of the sensor 300 relative to the mounting base 200 and ensuring the reliability and stability of the assembly.

[0053] The adhesive layer can be a sticky substance such as glue.

[0054] like Figure 3 As shown, in one embodiment, the mounting base 200 includes a non-electromagnetic body 250, and the sensing element 300 is disposed within the non-electromagnetic body 250. This avoids the sensing element's recognition of the sensing element 300 being affected by the electromagnetic shielding provided by the mounting base 200 after the sensing element 300 is placed within it.

[0055] Among them, the non-electromagnetic body 250 can be made of materials such as plastic that do not form electromagnetic shielding. Existing materials can be used, which will not be elaborated or listed here.

[0056] like Figure 3As shown, in one embodiment, the depth of the mounting groove 110 along the radial direction of the connecting post 100 matches the thickness of the mounting base 200. This ensures the circumferential smoothness of the connecting post 100, preventing interference or impact on the assembly of the connecting post 100 and the power handle, and guaranteeing normal power transmission.

[0057] It should be noted that the depth and thickness in the embodiments of this application refer to, as Figure 3 The depth or thickness in the H direction shown.

[0058] It should be noted that "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is only one embodiment for ease of reading, and is not intended to limit the scope of protection of this application.
