Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a navigation instrument package assembly used in surgical operations. Background Art
[0002] Surgical navigation combines modern imaging technology, computer technology, and spatial positioning technology to track the positions of the surgical instrument body and the patient's anatomical structure in real time during the operation and display them on a computer screen, providing intuitive and accurate surgical information for doctors, thereby assisting doctors in performing precise surgical operations.
[0003] Surgical navigation generally uses navigation devices such as a navigation host, a display screen, a tracker, a camera, etc., and also uses a plurality of navigation surgical instruments, instrument positioning parts, and registration tooling such as a calibration rod and a calibration plate for calibration. Currently, in order to establish a three-dimensional digital model of the surgical instrument body, during the operation, it is generally necessary to use special registration tooling to assemble, calibrate, and debug each surgical instrument body at the surgical site; if the repeated calibration fails, it is also necessary to replace the retroreflective sphere and then recalibrate, which will increase the preparation time of the operation and reduce the surgical efficiency. Moreover, to ensure the accuracy of the surgical instrument body and avoid cross-infection, if each navigation instrument package assembly is equipped with a set of calibration tools, it will inevitably increase the cost of the entire navigation instrument package. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide a navigation instrument package assembly used in surgical operations, calibrate the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument at the time of factory, and record the information in the information storage module provided on the instrument packaging component, so that it is not necessary to calibrate and debug each navigation surgical instrument during the operation, reducing the preparation time of the operation.
[0005] The present invention solves the above technical problems through the following technical means:
[0006] The present invention discloses a navigation instrument package assembly used in surgical operations, including an instrument packaging component and at least one navigation surgical instrument, and the navigation surgical instruments are all arranged within the instrument packaging component; there is a unique information storage module corresponding to all the navigation surgical instruments on or within the instrument packaging component; each of the navigation surgical instruments includes an integrated surgical instrument body and an instrument positioning part, and each of the instrument positioning parts is provided with at least 3 non-collinear tracking markers, and the tracking markers can reflect light or actively emit infrared light; each of the surgical instrument bodies has an instrument front end, and the information storage module records the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument.
[0007] When the navigation instrument kit component of the present technical solution leaves the factory, the spatial coordinate information of each tracking marker and the front end of the instrument on each navigation surgical instrument can be calibrated, and a unique information storage module is corresponding to each. Then all the surgical instruments are packed and placed in the instrument packaging component, and an information storage module is set on or inside the instrument packaging component. During the operation, by scanning the information storage module, the spatial coordinate information of each tracking marker and the front end of each navigation surgical instrument in the instrument packaging component can be identified. When medical staff use it, they only need to scan the information storage module with an external camera to read out the three-dimensional digital model of each navigation surgical instrument, without the need for calibration during the operation, which is simple and convenient to use and the data is more accurate.
[0008] Furthermore, the instrument packaging component is a packaging box or a packaging bag; the information storage module is one of a two-dimensional code, a bar code, a ColorCode code, and a Dot Code code; the information storage module is printed on the instrument packaging component, or a label is pasted on the instrument packaging component, and the information storage module is set on the label. These information storage modules can all record the spatial position information of each tracking marker and the front end of the instrument on each navigation surgical instrument. After using a camera to photograph the information storage module, the corresponding information can be read; during production, the information storage module can be directly printed on the packaging; or during production, a specific information storage module with information can be printed on a label first, and then the label with the information storage module can be pasted on the instrument packaging component, which is convenient for production.
[0009] Furthermore, the navigation instrument kit component further includes an information card, the information storage module is set on the information card, and the information card is located inside the instrument packaging component. With such a setting, the information storage module can also be set on the information card and then placed inside the instrument packaging component. When in use, take out the information card for identification, which is convenient to use.
[0010] Furthermore, the information storage module is an NFC or RFID electronic identification tag.
[0011] Furthermore, the spatial positions of the tracking markers on each navigation surgical instrument are 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 read simultaneously, which is convenient for medical staff during the operation.
[0013] Furthermore, the surgical instrument body includes one or more of a probe, a dissecting finger, and a suction tube.
[0014] Further, the tracking marker is a small ball with retroreflection, or a sticker with retroreflection function, or an LED lamp bead that actively emits infrared light. These optical markers above can all be tracked by an infrared binocular camera, and then a three-dimensional digital model of the surgical instrument is established.
[0015] Further, a connecting piece is arranged on the instrument positioning part, and the connecting piece is fixedly connected with the surgical instrument body.
[0016] Further, the number of the tracking markers is 3 or 4. Three or four tracking markers can not only ensure the accuracy and meet the tracking requirements, but also reduce the cost and the occlusion risk.
[0017] Advantages of the present invention:
[0018] 1. When the navigation instrument package assembly of the present invention leaves the factory, the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument can be calibrated, and a unique information storage module is corresponding to each. Then all the surgical instruments are packed and placed in a packaging box or a packaging bag, and another information storage module is set. During the operation, the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument in the instrument packaging part can be identified through the information storage module. When medical staff use it, they only need to scan the information storage module with an external camera, and then the three-dimensional digital model of each navigation surgical instrument can be read out, without the need for calibration during the operation. It is simple and convenient to use, saves the operation preparation time, and the data is more accurate.
[0019] 2. Each set of navigation surgical instruments of the present invention corresponds to a unique information storage module. The navigation surgical instruments can be used cyclically or disposable. For surgical instruments with relatively low cost, after being used once, medical staff can directly discard them without the need to disinfect the surgical instruments, which reduces the workload of the hospital and also avoids cross-infection that may be caused by incomplete disinfection.
[0020] 3. When the navigation surgical instruments of the present invention leave the factory, the spatial coordinate information of each tracking marker and the instrument front end on each navigation surgical instrument can be calibrated. In this way, there is no need to equip calibration tools in the navigation instrument package, thereby reducing the cost of the entire navigation instrument package. Description of the Drawings
