[0045] It should be noted that the directional terms such as "upper," "lower," "left," and "right" used in the embodiments of the present invention are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of the present invention. Furthermore, in the context, it should be understood that when it is mentioned that an element is formed "upper" or "lower" of another element, it can not only be formed directly "upper" or "lower" of the other element, but also indirectly "upper" or "lower" of the other element through an intermediate element.

[0046] The following is in conjunction with the appendix Figure 1-16 The structure of the orthopedic surgical drilling device provided in the embodiments of this application will be described.

[0047] Combined with appendix Figure 1 As shown, this application provides an orthopedic surgical drilling device for positioning drilling during surgery, such as for positioning drilling in spinal surgery. The orthopedic surgical drilling device mainly includes functional components such as a passive support arm 100, a connecting and adjusting component 200, a drilling adjusting component 300, a sleeve positioning component 400, and a drilling component 500.

[0048] In the aforementioned functional components, the passive support arm 100 has one end connected to the operating table 600, and the other end is a free end 111, which is configured to move vertically and / or horizontally under external force. The operating table 600 can be considered as part of the orthopedic surgical drilling device, or as an external structure independent of the orthopedic surgical drilling device.

[0049] In some embodiments, the free end 111 of this embodiment has three degrees of freedom for adjustment along the first direction X, the second direction Y, and the third direction Z in the figure, thereby enabling the position adjustment component 200, the drilling adjustment component 300, the sleeve positioning component 400, and the drilling component 500 connected at the free end 111 to be adjusted.

[0050] In this embodiment, the connection and adjustment component 200 is installed on the free end 111 and extends along the first direction X in its length direction. The first direction X can be understood as the drilling depth direction of the drilling component 500. Figure 1 In the diagram, the first direction X is the vertical direction.

[0051] In this embodiment, the drilling adjustment component 300 is installed on the connecting adjustment component 200. The connecting adjustment component 200 is configured to adjust the position of the drilling adjustment component 300 along the first direction X, thereby achieving preliminary adjustment of the positions of the drilling adjustment component 300 and the drilling component 500 in the first direction X.

[0052] In this embodiment, the sleeve positioning component 400 is installed at one end of the drilling adjustment component 300 along the first direction X and is used to abut against the skin during drilling. The sleeve body 430 of the sleeve positioning component 400 is provided with a serrated structure, which can abut against the skin, thereby reducing the possibility of the drilling component 500 slipping on the vertebra after entering the skin.

[0053] The drilling assembly 500 in this embodiment can be an ultrasonic drill 530 that uses ultrasonic waves to drill holes, or it can be an orthopedic surgical drilling structure in other related technologies, such as a structure that uses mechanical, electrical or vibration drilling. This embodiment will not elaborate on this further.

[0054] In this embodiment, the drilling assembly 500 is installed on the drilling positioning assembly 300 and is configured to move along the first direction X under the drive of the drilling positioning assembly 300, thereby realizing the movement of the drilling assembly 500 along the first direction X to perform drilling operations.

[0055] In this embodiment, a passive support arm 100 is used to connect the operating table 600, and the passive support arm 100 is used to install and connect the adjustment component 200, the drilling adjustment component 300, the sleeve positioning component 400, and the drilling component 500. This allows the drilling component 500 to be supported and fixed during surgery, eliminating the need for the operator to manually perform drilling operations. In addition, the position of the drilling component 500 along the first direction X can be adjusted using the adjustment component 200 and the drilling adjustment component 300, which is more conducive to placing the drilling component 500 in the optimal drilling position, thereby improving the efficiency and accuracy of drilling.

[0056] Combined with appendix Figure 2 As shown, in some examples, optionally, the lower end of the passive support arm 100 in this embodiment is provided with a first sliding connector 140. The first sliding connector 140 can be a slider with a groove for docking. Figure 1 The slide rail of the operating table 600 in the figure allows the first sliding connector 140 to slide on the operating table 600 along the second direction Y (one of the horizontal directions) in the figure.

[0057] In order to lock the passive support arm 100 after it slides, this embodiment may also have a sliding locking component (not shown in the figure). The sliding locking component may be a bolt or other structure. The sliding locking component may be inserted into the first sliding connector 140 and lock the first sliding connector 140 by cooperating with the slide rail.

[0058] In some examples, the passive support arm 100 of this embodiment optionally includes a first support member 110, a universal joint 120, and a first mounting member 130. The first support member 110 may be a rod-shaped member as shown in the figure. There are multiple first support members 110, such as the three shown in the figure. Multiple first support members 110 are connected end to end in sequence. One support member is slidably connected to the operating table 600, and another support member is provided with the free end 111 mentioned above and is used to connect to the first mounting member 130. The connection adjustment component 200 is installed on the first mounting member 130.

[0059] The first mounting component 130 in this embodiment can be a plate-shaped component as shown in the figure, or a block-shaped component, etc. This embodiment does not impose any restrictions on it.

[0060] A first universal joint 120 is provided between two adjacent first support members 110. The two adjacent first support members 110 are connected by the first universal joint 120. The first universal joint 120 can be a universal joint 120 structure with a self-locking structure. For example, the self-locking structure shown in the figure can lock the first universal joint 120, thereby restricting the relative rotation between the two adjacent first support members 110, so that the passive support arm 100 can maintain a stable support shape.

[0061] Combined with appendix Figure 3 As shown, in some examples, the connection adjustment assembly 200 may optionally include a first connector 210, a first guide rail 220, a first slider 230, a first elastic member 240, and a second connector 250.

[0062] The first connector 210 can be a plate or a block. The first connector 210 is installed on the passive support arm 100, specifically on the first mounting part 130 mentioned above. The installation method can be a mechanical connection method such as bolt connection or snap-fit.

[0063] One end (e.g., the upper end) of the first connector 210 is provided with a connecting ear 211 extending away from the passive support arm 100, and the connecting ear 211 is perpendicular to the first connector 210.

[0064] The first guide rail 220 is disposed on the surface of the first connector 210 away from the passive support arm 100. The first guide rail 220 can be a convex strip structure. The first sliding member 230 is slidably connected to the first guide rail 220 through the sliding groove on its lower side.

[0065] The second connector 250 is installed on the first sliding member 230, and the drilling and positioning assembly 300 is installed on the second connector 250. The installation method can be any kind of mechanical connection, such as bolt connection, rivet connection, etc., as long as it can satisfy the requirement that the sleeve positioning assembly 400 is fixed on the second connector 250.

[0066] The first elastic member 240 is connected to the connecting ear 211 and the second connecting member 250 respectively. By extending and retracting the first elastic member 240 along the first direction X, the position of the second connecting member 250 along the first direction X can be adjusted, thereby adjusting the position of the drilling adjustment assembly 300, the sleeve positioning assembly 400 and the drilling assembly 500 on the second connecting member 250 along the first direction X.

[0067] To improve the stability of the second connector 250 after adjustment and to limit the adjustment stroke, the connection adjustment assembly 200 of this embodiment also includes a first adjustment bolt 260. One end of the first adjustment bolt 260 passes through the through hole of the connecting ear 211 and can move in the sliding direction of the first sliding member 230 within the connecting ear 211. The first adjustment bolt 260 is limited to the surface of the connecting ear 211 opposite to the second connector 250 by its own nut 343.

[0068] The other end of the first adjusting bolt 260 is threadedly connected to the second connecting member 250, and the first elastic member 240 is sleeved on the first adjusting bolt 260.

[0069] One end of the first elastic element 240 abuts against the connecting ear 211, and the other end abuts against the second connecting element 250. The first elastic element 240 may be a spring.

[0070] When medical staff discover a risk during the drilling process and need to directly lift the drilling assembly 500, they operate the sleeve assembly to move the second connecting piece 250 upwards, thereby moving the drilling assembly 500. Once the risk is eliminated, the drilling assembly 500 can be reset by the elastic force of the first elastic member 240. This method is convenient and reduces the risk during drilling.

[0071] When it is necessary to extend the stroke of the second connector 250, the length of the exposed thread section of the first adjusting bolt 260 can be changed by turning the first adjusting bolt 260.

[0072] Combined with appendix Figure 4-6 As shown, in some examples, optionally, the drilling positioning assembly 300 of this embodiment includes a first mounting bracket 310, a second guide rail 320, a second sliding member 330, and a first linear reciprocating motion mechanism 340.

[0073] In this embodiment, the first mounting bracket 310 includes a first mounting plate 311 and a second mounting plate 312 and a third mounting plate 313 that are respectively vertically connected to opposite ends of the first mounting plate 311. The first mounting member 130 can be made of metal materials such as stainless steel or aluminum alloy, and the aforementioned first mounting member 130 can also be made of such materials.

[0074] The second guide rail 320 is connected to the first mounting plate 311 and is located between the second mounting plate 312 and the third mounting plate 313. The second guide rail 320 can be a strip-shaped protruding guide rail or a guide groove. This embodiment does not impose too many limitations on this.

[0075] In this embodiment, the sleeve positioning component 400 is installed on the second mounting plate 312. The installation method can be any structure that can install the sleeve positioning component 400 on the second mounting plate 312, such as bolt connection, snap-fit, plug-in, welding and other mechanical connection methods. This embodiment will not list them one by one.

[0076] The first linear reciprocating motion mechanism 340 is connected to the third mounting plate 313. The second sliding member 330 is slidably connected to the second guide rail 320 along the first direction X. The first linear reciprocating motion mechanism 340 is connected to the second sliding member 330 and is used to drive the second sliding member 330 to slide on the second guide rail 320. The drilling assembly 500 is installed on the second sliding member 330, so that the second sliding member 330 can drive the drilling assembly 500 to move along the first direction X.

[0077] In some embodiments, the first linear reciprocating motion mechanism 340 includes a motor 341, a lead screw 342, and a nut 343. The motor 341 is mounted on a third mounting plate 313, and the shaft of the motor 341 is connected to the lead screw 342. The lead screw 342 is rotatably mounted on the second mounting plate 312 and the third mounting plate 313. The nut 343 is connected to the lead screw 342, and the second sliding member 330 is fixedly connected to the nut 343. The lead screw 342 is rotated by the shaft, which in turn drives the nut 343 and the second sliding member 330 to move linearly in the first direction X.

[0078] Of course, the first linear reciprocating motion mechanism 340 in this embodiment is not limited to this. For example, the first linear reciprocating motion mechanism 340 may also include structures such as cylinders, hydraulic cylinders, and electric cylinders, which drive the second sliding member 330 to move along the first direction X through the cylinders.

[0079] Combined with appendix Figure 4 As shown, in some examples, optionally, the sleeve positioning assembly 400 includes a second mounting bracket 410, a first docking mechanism 420, and a sleeve body 430. The second mounting bracket 410 is fixedly mounted to the drilling positioning assembly 300, the first docking mechanism 420 is detachably mounted to the second mounting bracket 410, and the sleeve body 430 is detachably mounted to the first docking mechanism 420.

[0080] The sleeve body 430 is connected to the first docking mechanism 420. The sleeve body 430 has openings at both ends along the first direction X. The side wall of the sleeve body 430 is also provided with openings that connect to the openings at both ends respectively.

[0081] The second mounting bracket 410 can be installed on the second mounting plate 312 via bolts or other connecting parts. The first docking mechanism 420 and the second mounting bracket 410 are detachably connected, allowing for quick installation of the sleeve body 430 and the docking mechanism onto the second mounting bracket 410.

[0082] The sleeve body 430 can be detachably mounted on the first docking mechanism 420 for convenient installation. Specifically, the sleeve body 430 and the first mounting block 421 of the first docking mechanism 420 can be connected by bolts or the like.

[0083] In order to facilitate the quick installation of the first docking mechanism 420 on the second mounting bracket 410, this embodiment designs the first docking structure to include a first mounting block 421, a first rotating member 422, a first top block 423 and a first locking block 424.

[0084] In this embodiment, the second mounting bracket 410 is provided with a first limiting part 411 at both ends opposite to the first direction X on the side away from the drilling adjustment component 300. The first mounting block 421 is mounted on the second mounting bracket 410 and is located between the two first limiting parts 411.

[0085] The first mounting block 421 has a first groove 4211 with openings at both ends along the first direction X on the side facing the second mounting bracket 410. The first groove 4211 has a first limiting member 4212 on the side facing the second mounting bracket 410. The first limiting member 4212 can be a plate or a rod.

[0086] The first rotating member 422 can be a rotating shaft. The first rotating member 422 is inserted into the first groove 4211 along the second direction Y perpendicular to the first direction X. The first top block 423 is synchronously rotated and connected with the first rotating member 422. The first top block 423 is set facing the first locking block 424.

[0087] The first locking block 424 is inserted into the first groove 4211 and is located between the side of the first groove 4211 facing away from the second mounting bracket 410 and the first limiting member 4212. The side of the first locking block 424 facing the first top block 423 is provided with a first strip groove 4241 for accommodating part of the first top block 423. The first locking block 424 is provided with a first limiting end 4242 and a second limiting end 4243 arranged opposite to each other in the first direction X. The first limiting end 4242 and the second limiting end 4243 are respectively located on both sides of the first limiting member 4212.

[0088] During assembly, one side of the first mounting block 421 is first abutted against one of the first limiting parts 411, and then the first rotating member 422 is rotated, thereby causing the first top block 423 to rotate within the first groove 4211. When the first top block 423 rotates to abut against the inner wall of one end of the first strip groove 4241 along the first direction X, it drives the first locking block 424 to move along the first direction X, so that the first locking block 424 abuts against the other first limiting part 411.

[0089] In this embodiment, the first mounting block 421 presses one of the first limiting parts 411, and the first locking block 424 presses the other first limiting part 411, so that the entire first docking mechanism 420 is clamped between the two first limiting parts 411. This is convenient to operate and can improve the assembly efficiency of the docking mechanism and the second mounting bracket 410.

[0090] To facilitate the rotation of the first rotating component 422, a first handle 4221 can be connected to one end of the first rotating component 422. One end of the first handle 4221 is connected to the first rotating component 422. The groove wall of the first groove 4211 is provided with a first arc-shaped groove 42111. The first handle 4221 is provided with a sliding mating part (not shown in the figure) located in the first arc-shaped groove 42111. The rotation range of the first handle 4221 is limited by the guidance of the first arc-shaped groove 42111.

[0091] Combined with appendix Figure 1 Appendix Figure 12-16As shown, in some examples, optionally, the drilling assembly 500 of this embodiment includes a third mounting bracket 510, a second docking mechanism 520 and a drill 530. The third mounting bracket 510 is mounted on the drilling positioning assembly 300, the second docking mechanism 520 is detachably mounted on the third mounting bracket 510, and the drill 530 is detachably mounted on the second docking mechanism 520.

[0092] The third mounting bracket 510 can be specifically mounted on the aforementioned second sliding member 330. The second mounting block 521 of the second docking mechanism 520 has a similar structure to the aforementioned first mounting block 421. It can be provided with a first mounting hole 5213 and a first opening 5214 to facilitate the insertion of the drill 530 of this embodiment. The radial dimension of the second insertion hole can be adjusted by adjusting the size of the first opening 5214. The size of the first opening 5214 can also be locked by inserting a bolt into the first opening 5214.

[0093] The second docking mechanism 520 in this embodiment includes a second mounting block 521, a second rotating member 522, a second top block 523, and a second locking block 524.

[0094] The third mounting bracket 510 has a second limiting part 511 at both ends opposite to the first direction X on the side away from the drilling adjustment component 300. The second mounting block 521 is mounted on the third mounting bracket 510 and is located between the two second limiting parts 511.

[0095] The drill bit 530 is inserted into the second mounting block 521. The second mounting block 521 has a second groove 5211 with open ends along the first direction X on the side facing the third mounting bracket 510. The second groove 5211 has a second limiting member 5212 on the side facing the third mounting bracket 510.

[0096] The second rotating member 522 is inserted into the second groove 5211 along the second direction Y perpendicular to the first direction X. The second top block 523 is synchronously rotated and connected with the second rotating member 522. The second locking block 524 is inserted into the second groove 5211 and is located on the side of the second groove 5211 away from the third mounting bracket 510 and between the second limiting member 5212.

[0097] The second locking block 524 has a second strip groove 5241 for accommodating part of the second top block 523 on the side facing the second top block 523. The second locking block 524 has a third limiting end 5242 and a fourth limiting end 5243 arranged opposite to each other in the first direction X. The third limiting end 5242 and the fourth limiting end 5243 are located on both sides of the second limiting member 5212.

[0098] When installing the second docking mechanism 520, first abut one side of the second mounting block 521 against one of the second limiting parts 511. Then, by rotating the second rotating member 522, the second top block 523 is driven to rotate within the second groove 5211. When the second top block 523 rotates and abuts against the inner wall of one end of the second strip groove 5241 along the first direction X, it drives the second locking block 524 to move along the first direction X, so that the second locking block 524 abuts against the other second limiting part 511, thereby clamping the entire second docking mechanism 520 between the two second limiting parts 511.

[0099] In addition, a second handle 5221 connected to the second rotating member 522 can be provided to facilitate the rotation of the second rotating member 522. A second arc-shaped groove 52111 is opened on the groove wall of the second groove 5211 to slide and connect with the second handle 5221, thereby limiting the rotation stroke of the second handle 5221.

[0100] Alternatively, in some examples, the third mounting bracket 510 of this embodiment can be slidably connected to the drilling adjustment assembly 300 along the first direction X. Specifically, this can be achieved by setting a third guide rail 331 on the second sliding member 330, installing a third sliding member 3311 on the third guide rail 331, and allowing the third sliding member 3311 to slide along the third guide rail 331 along the first direction X. The third sliding member 3311 is connected to the third mounting bracket 510 described above through a second sliding connector 332.

[0101] The third mounting bracket 510 has a sensor clamping part 512 on the side facing the drilling and positioning assembly 300. The sensor clamping part 512 includes a first clamp 5121 and a second clamp 5122 connected to each other. The first clamp 5121 and the second clamp 5122 form a clamping space 5123 for clamping and mounting a pressure sensor (not shown in the figure). At least one side of the pressure sensor protrudes from the sensor clamping part 512 along the first direction X.

[0102] Correspondingly, the second slider 330 is provided with a receiving groove 333 for accommodating the sensor clamping part 512. The pressure sensor protrudes from one side of the sensor clamping part 512 and abuts against the side wall of the receiving groove 333, so that when the third mounting bracket 510 is displaced relative to the second slider in the first direction X, the pressure sensor can detect the pressure on the third mounting bracket 510 and the drilling assembly 500.
