Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a navigation instrument pack assembly used in surgical procedures. Background Technology
[0002] Surgical navigation combines modern imaging, computer, and spatial positioning technologies to track the position of surgical instruments and the patient's anatomical structures in real time during surgery and display it on a computer screen. This provides doctors with intuitive and accurate surgical information, thereby assisting them in performing precise surgical procedures.
[0003] Surgical navigation typically utilizes navigation devices such as a navigation unit, display screen, tracker, and camera, as well as multiple navigation surgical instruments, instrument positioning components, and registration fixtures such as calibration rods and plates. Currently, to create a 3D digital model of the surgical instruments, dedicated registration fixtures are generally required during surgery to assemble, calibrate, and adjust each instrument on-site. If repeated calibration fails, the reflector ball must be replaced and recalibrated, increasing preparation time and reducing surgical efficiency. Furthermore, to ensure the accuracy of the surgical instruments and prevent cross-infection, equipping each navigation instrument package component with a calibration tool would inevitably increase the overall cost of the navigation instrument package. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a navigation instrument package assembly for use in surgical procedures, which calibrates each tracking marker on each navigation surgical instrument and the spatial coordinate information of the instrument front end at the factory and records the information in an information storage module set on the instrument packaging component, eliminating the need to calibrate and adjust each navigation surgical instrument during surgery and reducing the preparation time for surgery.
[0005] This utility model solves the above-mentioned technical problems through the following technical means:
[0006] This utility model discloses a navigation instrument package assembly for use in surgical procedures, including an instrument packaging component and at least one navigation surgical instrument, all of which are disposed within the instrument packaging component. The instrument packaging component or its interior contains a unique information storage module corresponding to each navigation surgical instrument. Each navigation surgical instrument includes an integrated surgical instrument body and an instrument positioning component. Each instrument positioning component has at least three non-collinear tracking markers, which can reflect light or actively emit infrared light. Each surgical instrument body has an instrument front end. The information storage module records the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument.
[0007] The navigation instrument package component of this technical solution can calibrate the spatial coordinate information of each tracking marker and the front end of each navigation surgical instrument during the manufacturing process, and assign a unique information storage module to each. Then, all surgical instruments are packaged and placed inside the instrument packaging component, and an information storage module is set on or inside the instrument packaging component. During surgery, the spatial coordinate information of each tracking marker and the front end of each navigation surgical instrument can be identified by scanning the information storage module. When using it, medical personnel only need to scan the information storage module with an external camera to read the three-dimensional digital model of each navigation surgical instrument, without the need for calibration during surgery. It is simple and convenient to use, and the data is more accurate.
[0008] Furthermore, the instrument packaging component is a packaging box or bag; the information storage module is one of a QR code, barcode, color code, or dot code; the information storage module is printed on the instrument packaging component, or a label is affixed to the instrument packaging component, and the information storage module is located on the label. These information storage modules can record the spatial position information of each tracking marker on each navigation surgical instrument relative to the instrument's front end. After photographing the information storage module with a camera, the corresponding information can be read. During production, the information storage module can be directly printed on the packaging; alternatively, during production, specific information storage modules with information can be printed on labels first, and then the labels with information storage modules can be affixed to the instrument packaging component, simplifying production.
[0009] Furthermore, the navigation device package component also includes an information card, with the information storage module disposed on the information card, which is located inside the device packaging component. Alternatively, the information storage module can be disposed on the information card and then placed inside the device packaging component; the information card can be removed for identification during use, making it convenient to use.
[0010] Furthermore, the information storage module is an NFC or RFID electronic identification tag.
[0011] Furthermore, the spatial position of the tracking markers on each of the aforementioned navigation surgical instruments is different.
[0012] Furthermore, the information storage module also records the shape information of the surgical instrument body. The shape information of the surgical instrument body is simultaneously read, facilitating surgery for medical personnel.
[0013] Furthermore, the surgical instrument body includes one or more of a probe, a dissecting finger, and a suction tube.
[0014] Furthermore, the tracking marker can be a retroreflective sphere, a retroreflective sticker, or an LED bead that actively emits infrared light. All of these optical markers can be tracked by an infrared binocular camera, allowing for the creation of a three-dimensional digital model of the surgical instrument.
[0015] Furthermore, the instrument positioning component is provided with a connector, which is fixedly connected to the surgical instrument body.
[0016] Furthermore, the number of tracking markers is three or four. Three or four tracking markers can ensure accuracy and meet tracking requirements, while also reducing costs and the risk of occlusion.
[0017] The beneficial effects of this utility model are:
[0018] 1. During the manufacturing process of this utility model, the spatial coordinate information of each tracking marker and the front end of each navigation surgical instrument can be calibrated and assigned to a unique information storage module. Then, all surgical instruments are packaged in a box or bag, and an information storage module is set up. During surgery, the information storage module can identify the spatial coordinate information of each tracking marker and the front end of each navigation surgical instrument in the instrument packaging. When using it, medical personnel only need to scan the information storage module with an external camera to read the three-dimensional digital model of each navigation surgical instrument. There is no need to calibrate it again during surgery. It is simple and convenient to use, saves surgical preparation time, and the data is more accurate.
[0019] 2. Each set of navigation surgical instruments in this utility model corresponds to a unique information storage module. The navigation surgical instruments can be used repeatedly or used only once. For surgical instruments with relatively low cost, medical staff can discard them directly after single use without the need for further disinfection, which reduces the workload of the hospital and avoids cross-infection that may be caused by incomplete disinfection.
[0020] 3. The navigation surgical instruments of this utility model can be calibrated at the time of production, with each tracking marker and the spatial coordinate information of the instrument front end calibrated. This eliminates the need to equip the navigation instrument package with calibration tools, thereby reducing the cost of the entire navigation instrument package. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings:
[0030] Example 1
[0031] This embodiment describes a navigation instrument pack component used in surgical procedures, such as... Figure 1 and Figure 2 As shown, the device includes an instrument packaging component and multiple navigation surgical instruments 2, which are housed within the instrument packaging component. A unique information storage module corresponding to each navigation surgical instrument 2 is affixed to the instrument packaging component. Each navigation surgical instrument 2 includes a surgical instrument body 201 and an instrument positioning frame 202. A connecting rod 203 is integrally provided on the instrument positioning frame 202, and the connecting rod 203 is fixedly connected to the surgical instrument body 201. Each instrument positioning frame is equipped with a tracking marker, the spatial position of which is different for each navigation surgical instrument. The tracking marker can reflect light or actively emit infrared light (as shown in the attached diagram). Figure 1In the diagram, for ease of demonstration, the navigation surgical instrument 2 is located outside the instrument packaging component. There are multiple navigation surgical instruments, each comprising a surgical instrument body and an instrument positioning frame, with largely identical structures. Figure 1 (Only one of the navigation surgical instruments is shown in the image); the surgical instrument body 201 has an instrument front end 205, and the information storage module records the spatial coordinate information of each tracking marker on each navigation surgical instrument and the instrument front end 205, as well as the shape information of each surgical instrument body 201.
[0032] In practical use, the device packaging component can be a packaging box 1 or a packaging bag; in this embodiment, a packaging box 1 is selected. In practical use, the information storage module can use one of the following: a QR code, barcode, ColorCode, or Dot Code; it can also be an NFC or RFID electronic identification tag 101; in this embodiment, an RFID electronic identification tag 101 is selected.
[0033] The surgical instrument body 201 can be at least one of a probe, a dissecting finger, and a suction tube. In practical use, it can also be a surgical instrument such as a surgical scalpel, a surgical grinding head, or a surgical bone saw.
[0034] In practical use, the tracking marker can be a retroreflective ball 204, a retroreflective sticker, or an LED light bead that actively emits infrared light; all of these can be tracked by an infrared binocular camera, and then a three-dimensional digital model of the surgical instrument can be established; in this embodiment, the tracking marker is a retroreflective ball 204.
[0035] To ensure accuracy, meet tracking requirements, reduce costs, and minimize the risk of occlusion, the number of tracking markers can be three or four; in this embodiment, four are used as an example.
[0036] The navigation instrument package component of this embodiment includes an instrument packaging component and multiple navigation surgical instruments 2. During the manufacturing process, the spatial coordinate information of each tracking marker on each navigation surgical instrument 2 and the instrument front end 205 can be calibrated and correspond to a unique information storage module (RFID electronic identification tag 101 in this embodiment). Then, each surgical instrument is packaged and placed in a packaging box 1 or a packaging bag, and an RFID electronic identification tag 101 is set on the packaging box 1 or the packaging bag.
[0037] During surgery, medical personnel can use RFID electronic identification tags 101 to identify the spatial coordinates of each tracking marker on each navigation surgical instrument 2 within the instrument packaging component and the instrument front end 205, as well as the shape information of each surgical instrument body 201. By simply using the corresponding sensing device to read the RFID electronic identification tag 101 on the packaging box 1, the three-dimensional digital model of each navigation surgical instrument 2 can be read. There is no need to perform calibration during surgery, making it simple and convenient to use, and the data is more accurate.
[0038] In addition, each navigation surgical instrument 2 of this invention can be calibrated with the spatial coordinate information of each tracking marker and the instrument front end 205 at the time of manufacture, so there is no need to equip the navigation instrument package with calibration tools, thereby reducing the cost of the entire navigation instrument package.
[0039] Because each set of navigation surgical instruments 2 corresponds to a unique RFID electronic identification tag 101, it can be reused or used once. After use, medical staff can discard it directly without disinfecting the surgical instruments, which reduces the workload of the hospital and avoids cross-infection that may be caused by incomplete disinfection.
[0040] Example 2
[0041] like Figure 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the packaging component of this embodiment is a packaging bag 3, and the information storage unit is a QR code 301. Specifically, a label is affixed to the packaging bag, and the QR code 301 is printed on the label. Thus, during production, a specific QR code with information can be printed on the label first, and then the label with the QR code 301 can be affixed to the packaging bag 3, making production convenient.
[0042] Another difference is that the optical marker in this embodiment is a sticker 404 with retroreflective function.
[0043] Example 3
[0044] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the navigation device package component in this embodiment further includes an information card 7. The information storage module is an NFC electronic identification tag, which is set on the information card 7, and the information card 7 is placed inside the packaging box 5. In this embodiment, the NFC electronic identification tag is set on the information card 7, and then it is placed inside the packaging box 5. When in use, the information card 7 can be taken out for identification and reading, which is convenient to use.
