Description

Technical Field

[0001] This utility model relates to the field of orthopedic surgical navigation and positioning technology, specifically to a visual tool recognition device and system. Background Technology

[0002] Orthopedic surgical navigation and positioning systems are increasingly being used in orthopedic surgeries. Besides guiding surgeons in screw placement, they also visualize various tools used to manage the intervertebral disc during surgery. This allows surgeons to perform disc manipulation entirely under visible conditions, making the surgery more precise and safer.

[0003] The current method for visualizing tools is as follows: During surgery, the required tool is first selected on the software interface, then a tracker is installed on this tool. The tool is then registered using a registration station under the optical camera. After registration, the tool is displayed in the software interface. In actual surgery, multiple tools are needed, and each tool has multiple sizes. To avoid repeatedly disassembling and reassembling the tracker during surgery, multiple trackers are currently configured. During the surgical preparation phase, different trackers are installed on different tools and registered using the registration station, thus ensuring rapid switching between different tools during surgery.

[0004] The current approach requires registering multiple tools during the operation and repeatedly disassembling and reassembling them when changing tools, thus prolonging the operation time; in addition, it requires configuring multiple trackers, which significantly increases the cost of the tools. Utility Model Content

[0005] To address the shortcomings of existing technologies, a visual tool identification device and system are proposed. This device solves the problems of repeated disassembly and assembly, which prolongs the operation time, and the need to configure multiple trackers, which significantly increases the cost of the tools.

[0006] To achieve the above objectives, the present invention proposes the following technologies:

[0007] A visual tool identification device includes a tracker body, a tool detachably connected to the tracker body, a first sensing part disposed on the tracker body, and a second sensing part disposed on the tool that matches the first sensing part. The tool is snapped into the tracker body so that the second sensing part can approach the first sensing part, thereby realizing tool visualization.

[0008] Furthermore, one end of the tracker body is provided with a tool interface for fixing a tool, and the first sensing part is disposed on the periphery of the tool interface so as to be close to the second sensing part on the tool that is snapped into the tool interface.

[0009] Furthermore, the tracker body is provided with a first latching part and a second latching part, and the tool interface is formed between the first latching part and the second latching part. The first sensing part is located in the first latching part, and the second latching part is provided with a latching block for fixing the tool.

[0010] Furthermore, the snap-fit ​​block is fixedly connected to the guide rod, the guide rod passes through the second snap-fit ​​part and is connected to the end of the snap-fit ​​cap, and a snap-fit ​​spring is provided between the second snap-fit ​​part and the snap-fit ​​block, the snap-fit ​​spring being located in a receiving groove opened on the side of the second snap-fit ​​part near the snap-fit ​​block.

[0011] Furthermore, the end face of the snap-fit ​​block is inclined, the tool is provided with an abutment surface that matches the snap-fit ​​block, and a snap-fit ​​groove for snapping the snap-fit ​​block. The first snap-fit ​​part is provided with a limiting groove that matches the shape of the tool end to achieve a stable connection between the tool and the tracker body.

[0012] Furthermore, it also includes a quick-release handle, which is detachably connected to the connector on the tracker body. The quick-release handle is provided with a quick-release interface to facilitate plugging into the connector and achieve a stable connection between the quick-release handle and the tracker body.

[0013] Furthermore, the quick-install interface includes a handle head, a stop block is slidably connected inside the handle head, the stop block has a plug hole for plugging in a connector, the connector has a plug groove, after the connector passes through the plug hole, the stop block slides into the plug groove and engages with the connector to realize the installation of the quick-install handle.

[0014] Furthermore, the first sensing unit includes a plurality of magnet mounting slots for mounting magnets, and the second sensing unit is specifically a magnetic control switch. The tool engages with the tracker body so that the magnet in the magnet mounting slot approaches the magnetic control switch to achieve the closing of the magnetic control switch.

[0015] Furthermore, the tool is provided in multiple ways, and the number and position of magnets in the magnet mounting slots on the multiple tools are different. The magnetic control switch is provided in several ways, and the magnets in different positions and numbers on the multiple tools cooperate with different magnetic control switches to generate different closing signals.

[0016] A visualization tool recognition system includes any of the visualization tool recognition devices described above, and also includes a host computer. After the tracker body receives the signal generated by the first sensing unit, it sends the signal to the host computer that is signal-connected to the tracker body. The host computer matches the signal with database information and then calls up the relevant data to display it on the software interface, thereby realizing the visualization of the tool.

[0017] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0018] By setting a first sensing unit and a second sensing unit, the tool and the tracker body can be detachably connected. By using different tools with the tracker body, different second sensing units approach the first sensing unit to generate different signals on the tracker body. Thus, different tools can be visualized through the tracker body, achieving the goal of visualizing multiple tools through one tracker body. This solves the problem of multiple trackers registering multiple tools and the time-consuming and laborious process of repeated disassembly and assembly in the prior art, while also reducing the cost of using the tracker.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] like Figure 1 and Figure 6 As shown, a visual tool identification device includes a tracker body 1, on which a tool 2 is detachably connected. The tracker body 1 is provided with a first sensing part, and the tool 2 is provided with a second sensing part that matches the first sensing part. The tool 2 is snapped into the tracker body 1 so that the second sensing part can approach the first sensing part, thereby making the tool 2 visible.

[0030] By setting a first sensing part and a second sensing part, the tool 2 is detachably connected to the tracker body 1. By having different tools 2 cooperate with the tracker body 1, different second sensing parts approach the first sensing part to make the tracker body 1 generate different signals, thereby realizing the visualization of different tools 2 through the tracker body 1. This achieves the goal of realizing the visualization of multiple tools 2 through one tracker body 1, solving the problem of multiple trackers registering multiple tools 2 in the prior art, which is time-consuming and laborious due to repeated disassembly and assembly, and at the same time reducing the cost of using the tracker.

[0031] In the visual tool recognition device of this embodiment, one end of the tracker body 1 is provided with a tool interface for fixing the tool 2, and the first sensing part is provided on the periphery of the tool interface so as to be close to the second sensing part on the tool 2 that is snapped into the tool interface.

[0032] By setting a tool interface, it is easy to assemble and disassemble the tool 2 and the tracker body 1, reducing the installation difficulty and improving the efficiency of changing different tools 2. The first sensing part is set on the side of the tracker body 1 where the tool interface is set, which improves the matching accuracy between the first sensing part and the second sensing part, and makes it easier for the tracker body 1 to generate signals to realize the visualization of the tool 2. Preferably, the second sensing part is set at the end of the tool 2 that is snapped into the tool interface, which further reduces the distance between the first sensing part and the second sensing part and improves the matching accuracy.

[0033] In the visual tool recognition device of this embodiment, the tracker body 1 is provided with a first latching part 3 and a second latching part 4, and the tool interface is formed between the first latching part 3 and the second latching part 4. The first sensing part is located in the first latching part 3, and the second latching part 4 is provided with a latching block 5 for fixing the tool 2.

[0034] Specifically, tool 2 is connected to tracker body 1 by snapping between first snap-fit ​​part 3 and second snap-fit ​​part 4. One end of tool 2 abuts against first snap-fit ​​part 3 to approach first sensing part so that tracker body 1 generates a signal for visualization. The other end of tool 2 is fixed to tracker body 1 by engaging with snap-fit ​​block 5. Adjusting the relative position of snap-fit ​​block 5 and second snap-fit ​​part 4 allows tool 2 to be snapped or released, facilitating the disassembly and replacement of different tools 2 and improving the efficiency of tool 2 installation and replacement.

[0035] In the visual tool recognition device of this embodiment, the snap-fit ​​block 5 is fixedly connected to the guide rod 6, the guide rod 6 passes through the second snap-fit ​​part 4 and is connected to the end of the removable cap 7, and a snap-fit ​​spring 8 is provided between the second snap-fit ​​part 4 and the snap-fit ​​block 5. The snap-fit ​​spring 8 is located in the receiving groove opened on the side of the second snap-fit ​​part 4 near the snap-fit ​​block 5.

[0036] With the above configuration, the guide rod 6 is slidably connected to the second snap-fit ​​part 4. The snap-fit ​​block 5 and the easy-release cap 7 are located on both sides of the second snap-fit ​​part 4. The easy-release cap 7 limits the guide rod 6. When installing the tool 2, pulling the easy-release cap 7 causes the guide rod 6 and the snap-fit ​​block 5 to compress the snap-fit ​​spring 8 and move upward, making it easier for the tool 2 to be placed into the tool interface. After the tool 2 is in place, the easy-release cap 7 is released, and the snap-fit ​​spring 8 returns to its original position and extends, causing the snap-fit ​​block 5 and the guide rod 6 to move downward, and the tool 2 is snapped and fixed by the snap-fit ​​block 5.

[0037] Specifically, the receiving groove is opened at the bottom of the second snap-fit ​​part 4, and two are symmetrically arranged about the guide rod 6. There are two corresponding snap-fit ​​springs 8. The two snap-fit ​​springs 8 are respectively connected to the top two sides of the snap-fit ​​block 5 so that the snap-fit ​​block 5 is evenly stressed and the clamping force of the snap-fit ​​block 5 on the tool 2 is increased. The receiving groove is set to guide the snap-fit ​​springs 8 and prevent the snap-fit ​​springs 8 from bending and deforming, which would affect normal extension and retraction.

[0038] Preferably, the two ends of the easy-release cap 7 are respectively provided with pressing blocks. The two pressing blocks make the easy-release cap 7 snap into place above the second snap-fit ​​part 4. The pressing blocks make it easy for the staff to grasp the easy-release cap 7 and pull it to realize the installation or removal of different tools 2. At the same time, the pressing blocks play a certain guiding role for the easy-release cap 7, increasing the contact area between the easy-release cap 7 and the second snap-fit ​​part 4, and improving the connection stability between the easy-release cap 7 and the second snap-fit ​​part 4.

[0039] In the visual tool recognition device of this embodiment, the end face of the snap-fit ​​block 5 is inclined, the tool 2 is provided with an abutment surface 9 that matches the snap-fit ​​block 5, and a snap-fit ​​groove 10 for snapping the snap-fit ​​block 5. The first snap-fit ​​part 3 is provided with a limiting groove 11 that matches the shape of the end of the tool 2 so as to realize the stable connection between the tool 2 and the tracker body 1.

[0040] Specifically, the contact surface 9 is inclined, and the inclination angle is the same as the inclination angle of the end face of the locking block 5. With the above setting, the contact surface 9 and the locking block 5 can slide relative to each other, pushing the tool 2 to move. With the cooperation of the inclined surface, the contact surface 9 pushes the locking block 5 and the guide rod 6 to move upward in the vertical direction, while compressing the locking spring 8 until the locking block 5 is separated from the contact surface 9. At this time, the locking spring 8 extends and pushes the locking block 5 into the locking groove 10 to achieve locking. The above installation process only requires pushing the tool 2, which is convenient to install and simple to operate, greatly reducing the assembly time of the tool 2 and the tracker body 1, thereby shortening the operation time.

[0041] Preferably, the tool interface is provided with an abutment block. When the tool 2 is inserted into the tool interface, the abutment surface 9 abuts against the abutment block. The abutment block further limits the tool 2 and improves the connection strength between the tool 2 and the tracker body 1.

[0042] Specifically, the tool 2 is provided with locking protrusions on both sides of the end that is locked to the first locking part 3. There are two corresponding limiting grooves 11 on the first locking part 3. The top surface of the limiting grooves 11 is inclined. By cooperating with the locking protrusions and the limiting grooves 11, the lower end of the tool 2 is stably locked to the tracker body 1, thereby improving the connection stability between the tool 2 and the tracker body 1.

[0043] Preferably, the second sensing part is located between the two snap-fit ​​protrusions on the tool 2, and the first sensing part is located between the two limiting grooves 11 on the first snap-fit ​​part 3. The above arrangement ensures that when the tool 2 is snap-fitted to the tracker body 1, the first sensing part and the second sensing part are in contact, so that the tracker body 1 can stably generate signals and ensure the visualization effect of the tool 2.

[0044] The visualization tool recognition device in this embodiment also includes a quick-release handle 12, which is detachably connected to the connector 13 on the tracker body 1. The quick-release handle 12 is provided with a quick-release interface so as to facilitate plugging into the connector 13 to achieve a stable connection between the quick-release handle 12 and the tracker body 1.

[0045] Specifically, the quick-install interface includes a handle head 14, a stop 15 is slidably connected inside the handle head 14, the stop 15 has a plug hole 16 for plugging in the connector 13, the connector 13 has a plug groove 17, after the connector 13 passes through the plug hole 16, the stop 15 slides into the plug groove 19 and engages with the connector 13 to install the quick-install handle 12.

[0046] Specifically, the handle head 14 has a groove for the sliding of the stop 15. A push spring is provided between the bottom of the groove and the stop 15. Pressing the stop 15 compresses the push spring, causing the insertion hole 16 to move down, making it easier for the connector 13 to be inserted into the handle head 14. When the connector 13 is inserted a certain distance so that the insertion groove 17 is located in the insertion hole 16, the push spring returns to its original position and pushes the stop 15 to move upward and engage in the insertion groove 17, thereby limiting the connector 13 and completing the installation of the quick-release handle 12 and the tracker body 1.

[0047] Preferably, mounting holes communicating with the slide groove are respectively opened on both sides of the handle head 14 to install the limiting pin. The end of the limiting pin extends into the slide groove. The two sides of the stop block 15 are provided with waist-shaped holes corresponding to the limiting pin. The limiting pin is slidably connected in the waist-shaped hole. The sliding stroke of the stop block 15 is limited by the cooperation between the limiting pin and the waist-shaped hole, so as to prevent the stop block 15 from falling out of the slide groove. This makes it easier for the staff to install the stop block 15 to realize the quick installation and disassembly of the quick-install handle 12 and improve the assembly efficiency.

[0048] Preferably, the end of the connector 13 is configured as a flat conical structure. With the above structure, when the connector 13 is inserted into the handle head 14, the conical head of the connector 13 contacts the insertion hole 16 and pushes the stop block 15 downward through the inclined surface to facilitate the insertion of the connector 13 into the insertion hole 16 until the stop block 15 is pushed into the insertion groove 17 by the push spring to achieve the snap-fit. That is, only the insertion action is needed to realize the installation of the quick-install handle 12, thereby improving the assembly efficiency.

[0049] In the visual tool recognition device of this embodiment, the first sensing part includes a plurality of magnet mounting slots 18 for mounting magnets, and the second sensing part is specifically a magnetic control switch 19. The tool 2 is engaged with the tracker body 1 so that the magnet in the magnet mounting slot 18 approaches the magnetic control switch 19 to achieve the closing of the magnetic control switch 19.

[0050] Specifically, the magnet mounting slot 18 is located between two snap-fit ​​protrusions at the end of the tool 2, and the magnetic control switch 19 is located between two limiting slots 11 of the tracker body 1. The tracker body 1 also has a main circuit board inside, and the magnetic control switch 19 is electrically connected to the main circuit board. When the tool 2 is assembled with the tracker body 1, the magnet in the magnet mounting slot 18 approaches the magnetic control switch 19, and the magnetic control switch 19 closes to generate a signal that is transmitted to the main circuit board. After the chip on the built-in main circuit board receives the corresponding magnetic control switch 19 closing signal, it sends this signal to the external receiver that cooperates with the tracker body 1 via Bluetooth. The receiver analyzes and processes the signal generated by the matching of the tool 2 and the magnetic control switch 19 to realize the visualization of the tool 2.

[0051] In the visual tool recognition device of this embodiment, multiple tools 2 are provided, and the number and position of magnets in the magnet mounting slots 18 on the multiple tools 2 are different. Several magnetic control switches 19 are provided, and the magnets in different positions and numbers on the multiple tools 2 cooperate with different magnetic control switches 19 to generate different closing signals.

[0052] Specifically, multiple magnetic switches 19 are mounted on a mounting plate for easy fixation to the tracker body 1. Magnets of varying positions or numbers are arranged on the tools 2 to be visualized. The number of identifiable tools 2 depends on the number of magnet channels. If there are N magnet channels and N magnet mounting slots 18, the number of identifiable tools 2 is: 2 N -1.

[0053] Different visualization tools 2 have different magnet installation configurations. After the tool 2 is installed on the tracker body 1, the different magnet installation configurations will cooperate with the magnetic control switches 19 at different positions to trigger the magnetic control switches 19 at the corresponding positions to close, thereby generating different closing signals to achieve the identification and visualization of different tools 2.

[0054] Preferably, the tracker in this embodiment uses an active light-emitting diode, has a built-in magnetic switch circuit and Bluetooth communication circuit, and is powered by a battery. A back cover is detachably connected to the bottom of the tracker body 1, and the back cover facilitates opening the tracker body 1 for internal structural inspection.

[0055] In addition to Bluetooth, other wireless communication solutions such as RFID and NFC, or other wireless coding integrated circuits (such as EV1527) can also be used. This device can be used not only to identify different intervertebral disc treatment tools in spinal surgery, but also to identify different probes in joint surgery.

[0056] On the other hand, such as Figure 7As shown, this application also proposes a visualization tool recognition system, including the visualization tool recognition device described in any of the above embodiments, and also includes a host computer. After the tracker body 1 receives the signal generated by the first sensing unit, it sends the signal to the host computer that is connected to the tracker body 1. The host computer matches the signal with the database information and calls the relevant data to display it on the software interface, thereby realizing the visualization of the tool 2.

[0057] Specifically, after the chip on the built-in main circuit board receives the closing signal of the corresponding magnetic switch 19, it sends this signal to the host computer on the control vehicle via Bluetooth. After receiving the information, the host computer performs matching and identification. After matching with the information in the database, it ensures that the tracker body 1 is in the field of view of the optical camera, and then calls up the relevant data to display on the software interface, thereby realizing the visualization display of tool 2.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0059] Although embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
