[0023] The following is combined with Figure 1-16 The structure of the orthopedic surgical drilling device provided in an embodiment of the present application is introduced.

[0024] Combined with attachment Figure 1 As shown, an embodiment of the present application provides an orthopedic surgical drilling device for positioning drilling during surgery, such as positioning drilling in spinal surgery. The orthopedic surgical drilling device mainly includes functional components such as a passive support arm 100, a connection adjustment component 200, a drilling adjustment component 300, a sleeve positioning component 400, and a drilling component 500.

[0025] In the functional assembly described above, one of the opposite ends of the passive support arm 100 is connected to the operating table 600, and the other end is a free end 111. The free end 111 is configured to move vertically and / or horizontally under the action of an 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.

[0026] In some embodiments, the free end 111 of this embodiment has three degrees of adjustment freedom along the first direction X, the second direction Y and the third direction Z in the figure, so that the connection adjustment assembly 200, the drilling adjustment assembly 300, the sleeve positioning assembly 400 and the drilling assembly 500 at the free end 111 can be adjusted in position.

[0027] The connection adjustment component 200 of this embodiment is installed at the free end 111, and the length direction extends along the first direction X. The first direction X can be understood as the drilling depth direction of the drilling component 500. Figure 1 , the first direction X is a vertical direction.

[0028] The drilling adjustment assembly 300 of this embodiment is installed on the connecting adjustment assembly 200, and the connecting adjustment assembly 200 is configured to be able to adjust the position of the drilling adjustment assembly 300 along the first direction X, thereby realizing preliminary adjustment of the position of the drilling adjustment assembly 300 and the drilling assembly 500 in the first direction X.

[0029] The sleeve positioning assembly 400 of this embodiment is installed at one end of the drilling adjustment assembly 300 along the first direction X, and is used to abut against the skin when drilling. The sleeve body 430 of the sleeve positioning assembly 400 is provided with structures such as serrations, which can abut against the skin, thereby reducing the possibility of the drilling assembly 500 slipping on the vertebral body after entering the skin.

[0030] The drilling assembly 500 of this embodiment can be an ultrasonic drill 530 that uses ultrasonic waves to perform drilling. Of course, it can also 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.

[0031] The drilling assembly 500 of this embodiment is installed on the drilling position adjustment assembly 300 and is configured to move along the first direction X driven by the drilling position adjustment assembly 300, thereby realizing the movement of the drilling assembly 500 along the first direction X to perform drilling operations.

[0032] This embodiment uses a passive support arm 100 to dock the operating table 600, and uses the passive support arm 100 to install the connection adjustment component 200, the drilling adjustment component 300, the sleeve positioning component 400 and the drilling component 500, so that the drilling component 500 can be supported and fixed during surgery, without the need for the operator to hold the drilling operation; in addition, the connection adjustment component 200 and the drilling adjustment component 300 can be used to adjust the position of the drilling component 500 along the first direction X, which is more conducive to the drilling component 500 being in the optimal drilling position, thereby improving the efficiency and accuracy of drilling.

[0033] Combined with attachment Figure 2 As shown, in some examples, optionally, the lower end of the passive support arm 100 of this embodiment is provided with a first sliding connection member 140, and the first sliding connection member 140 can be a slider with a slide groove for docking. Figure 1 The slide rail of the operating table 600 is connected to the operating table 600, so that the first sliding connection member 140 can slide on the operating table 600 along the second direction Y in the figure (one of the horizontal directions).

[0034] In order to lock the passive support arm 100 after sliding, this embodiment may also have a sliding locking member (not shown in the figure). The sliding locking member may be a bolt or other structure. The sliding locking member may be inserted into the first sliding connector 140 and the locking of the first sliding connector 140 is achieved by cooperating with the slide rail.

[0035] In some examples, optionally, the passive support arm 100 of this embodiment includes a first support member 110, a universal joint 120 and a first mounting member 130. The first support member 110 can be a rod-shaped member as shown in the figure. The number of first support members 110 is multiple, for example, three as shown in the figure. The multiple first support members 110 are connected end to end in sequence, one of the support members is slidably connected to the operating table 600, and the other support member is provided with the above-mentioned free end 111 and is used to connect to the first mounting member 130, and the connection adjustment assembly 200 is installed on the first mounting member 130.

[0036] The first mounting member 130 of this embodiment can be a plate-shaped member as shown in the figure, or a block-shaped member, etc., and this embodiment does not impose too many restrictions on this.

[0037] A first universal joint 120 is provided between two adjacent first support members 110, and 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 first universal joint 120 can be locked by the self-locking structure in the figure, thereby limiting the relative rotation between the two adjacent first support members 110, so that the passive support arm 100 can maintain a stable support form.

[0038] Combined with attachment Figure 3 As shown, in some examples, optionally, the connection adjustment assembly 200 includes a first connection member 210 , a first guide rail 220 , a first sliding member 230 , a first elastic member 240 and a second connection member 250 .

[0039] The first connecting member 210 can be a plate-shaped member or a block-shaped member. The first connecting member 210 is installed on the passive support arm 100, specifically, on the above-mentioned first mounting member 130, and the mounting method can be a mechanical connection method such as bolt connection and clamping.

[0040] A connecting ear 211 extending away from the passive support arm 100 is provided at one end (eg, the upper end) of the first connecting member 210 . The connecting ear 211 is perpendicular to the first connecting member 210 .

[0041] The first guide rail 220 is disposed on the surface of the first connecting member 210 away from the passive support arm 100 . The first guide rail 220 may be a convex strip structure. The first sliding member 230 is slidably connected to the first guide rail 220 via a sliding groove on its lower side.

[0042] The second connecting member 250 is installed on the first sliding member 230, and the drilling adjustment assembly 300 is installed on the second connecting member 250. The installation method can be any mechanical connection, such as bolt connection, rivet connection, etc., as long as it can meet the requirements of fixing the sleeve positioning assembly 400 on the second connecting member 250.

[0043] The first elastic member 240 is respectively connected to the connecting ear 211 and the second connecting member 250. By expanding and contracting 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.

[0044] In order to improve the stability of the second connecting member 250 after adjustment and limit the adjustment stroke, the connection adjustment assembly 200 of this embodiment also includes a first adjusting bolt 260, one end of which is passed through the through hole of the connecting ear 211 and can move in the connecting ear 211 along the sliding direction of the first sliding member 230. The first adjusting bolt 260 is limitedly engaged with the surface of the connecting ear 211 on the side away from the second connecting member 250 through its own nut 343.

[0045] 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 .

[0046] One end of the first elastic member 240 abuts against the connecting ear 211 , and the other end abuts against the second connecting member 250 . The first elastic member 240 may be a spring.

[0047] If medical personnel detect 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 member 250 upward, thereby driving the movement of the drilling assembly 500. When the risk is resolved, the elastic force of the first elastic member 240 can reset the drilling assembly 500. This facilitates operation and reduces risks during the drilling process.

[0048] When it is necessary to extend the stroke of the second connecting member 250 , the first adjusting bolt 260 can be screwed to change the length of the exposed threaded section of the first adjusting bolt 260 for adjustment.

[0049] Combined with attachment Figure 4-6 As shown, in some examples, optionally, the drilling adjustment assembly 300 of this embodiment includes a first mounting frame 310 , a second guide rail 320 , a second sliding member 330 , and a first linear reciprocating motion mechanism 340 .

The first mounting member 130 can be made of metal materials such as stainless steel or aluminum alloy, and the above-mentioned first mounting member 130 can also be made of the same.

[0051] 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 bar-shaped raised guide rail or a guide groove, which is not limited in this embodiment.

[0052] The sleeve positioning assembly 400 of this embodiment is installed on the second mounting plate 312. The installation method can be any structure that can install the sleeve positioning assembly 400 on the second mounting plate 312, such as bolt connection, clamping, plug-in, welding and other mechanical connection methods, which are not listed one by one in this embodiment.

[0053] The first linear reciprocating motion mechanism 340 is connected to the third mounting plate 313, and 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.

[0054] In some embodiments, the first linear reciprocating motion mechanism 340 includes a motor 341, a screw rod 342 and a nut 343. The motor 341 is installed on the third mounting plate 313. The rotating shaft of the motor 341 is connected to the screw rod 342. The screw rod 342 is rotatably mounted on the second mounting plate 312 and the third mounting plate 313. The nut 343 is connected to the screw rod 342. The second sliding member 330 is fixedly connected to the nut 343.
