[0039] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] First, refer to Figure 1 as well as Figure 2 As shown, the present invention provides a skull model 10, comprising a skull base 11 and a temporal bone replacement block 12, wherein:

[0041] The skull base 11 is the main part of the skull model 10, and the temporal bone replacement block 12 can be detachably connected to the skull base 11. Compared with the integrated structure of the skull model 10 in the prior art, after completing a skull surgery simulation training, there is no need to disassemble and replace the skull model 10. Only the used skull base 11 or temporal bone replacement block 12 needs to be replaced, which can effectively avoid the problem of waste of resources.

[0042] The temporal bone replacement block 12 includes a temporal bone base 121 and an inner ear replacement block 122. The temporal bone base 121 is detachably connected to the skull base 11 and the inner ear replacement block 122, respectively. At least a portion of the temporal bone base 121 is located within the skull base 11, and at least a portion of the inner ear replacement block 122 is located within the temporal bone base 121. In the embodiment provided herein, the temporal bone base 121 is detachably connected to the skull base 11, and the temporal bone base 121 is detachably connected to the inner ear replacement block 122. This makes the skull model 10 suitable for a wide range of surgical simulation training. For each surgical simulation, only the corresponding structure needs to be selected for operation. This avoids the problem of partial structures of the skull model 10 being used for surgical simulation, rendering the entire model unusable, which would otherwise result in a waste of resources.

[0043] In one feasible embodiment, the detachable connection between the temporal bone base 121 and the skull base 11 is a magnetic snap-fit ​​connection. In other embodiments, the temporal bone base 121 and the skull base 11 may also be connected by snap-fit ​​connection, riveted connection, bolted connection, or adhesive connection, which are not limited here. The connection between the temporal bone base 121 and the inner ear replacement block 122 is an embedded connection. In other embodiments, the temporal bone base 121 and the inner ear replacement block 122 may also be connected by riveted connection, bolted connection, magnetic connection, snap-fit ​​connection, or adhesive connection, which are not limited here.

[0044] Furthermore, the skull base 11 includes at least one of the frontal bone, brow arch, glabella, orbit, nasal bone, zygomatic bone, sigmoid sinus, maxillary bone and mandibular body. The skull base 11 may also include more or less tissue structures in the human skull, which is not limited here. The temporal bone base 121 includes at least one of the external auditory meatus, part of the petrous part, styloid process, and mastoid air cell. The temporal bone base 121 may also include more or less tissue structures in and around the human temporal bone, which is not limited here. The inner ear replacement block 122 includes at least one of part of the petrous part, cochlea, semicircular canal, ossicular chain, facial nerve, internal carotid artery, chorda tympani, tympanic membrane, middle ear cavity and internal auditory meatus. The inner ear replacement block 122 may also include more or less tissue structures in and around the human inner ear, which is not limited here.

[0045] Since the softness and hardness of various tissue structures in the human skull are different, the skull model 10 can be made of soft materials and hard materials with different hardnesses through 3D printing technology to achieve a better simulation effect. In the embodiment provided in this application, the skull base 11 and the temporal bone base 121 are bone-like structures and need to be printed using a printing material with a higher hardness, so that the hardness of the skull base 11 and the temporal bone base 121 is greater than the hardness of the inner ear replacement block 122, thereby achieving a better simulation effect. In a feasible embodiment, the soft material and the hard material include resin materials and / or silicone materials, and the 3D printing technologies that can be used include but are not limited to: stereolithography technology (SLA), digital light processing technology (DLP), three-dimensional printing technology (3DP), multi-jet melting technology (MJF) and various other types of 3D printing or additive manufacturing technologies known in the art, which are not limited here.

[0046] Secondly, refer to Figure 3 As shown, the present invention provides a skull surgery simulation device, using the aforementioned skull model 10, including a fixing seat 20 and a positioning portion 30, wherein:

[0047] The fixing base 20 includes a tray 21 and a movable member 22. The movable member 22 is disposed within the tray 21, and the skull model 10 is detachably connected to the movable member 22. The fixing base 20 is used to securely support the skull model 10. The movable member 22 has multiple degrees of freedom for adjustment. Since the movable member 22 is connected to the skull model 10, the position of the skull model 10 can be easily adjusted. In the embodiment provided herein, the movable member 22 is connected to the skull model 10 via bolts. In other embodiments, the skull model 10 and the movable member 22 can be connected and fixed using at least one of a snap-fit ​​connection, a magnetic connection, a riveted connection, and an adhesive connection, which are not limited here. Because the temporal bone base 121 of the skull model 10 is detachably connected to the skull base 11 and the inner ear replacement block 122, after the skull model 10 completes a surgical simulation on the fixing base 20, only the used module needs to be replaced, avoiding waste of resources and improving the efficiency of preoperative preparation for the next surgical simulation.

[0048] Reference Figure 4 As shown, the fixing seat 20 also includes a water-absorbing component 23 and an anti-slip component 24. The water-absorbing component 23 is arranged in the tray 21. During the skull surgery simulation training, model waste may be generated. At this time, it is necessary to rinse the model waste with water to prevent the model waste from adhering to the model and affecting the medical staff's field of vision. After rinsing with water, some of the waste liquid may fall into the tray 21. The water-absorbing component 23 in the tray 21 can absorb the waste liquid. When the amount of waste liquid falling into the tray 21 is large, the water-absorbing component 23 that absorbs more waste liquid can be replaced, which is conducive to improving the cleaning efficiency of the waste liquid. The anti-slip component 24 is arranged at the bottom of the tray 21. During the skull surgery simulation, it can prevent the entire device from shifting, thereby affecting the simulation of the surgery.

[0049] Reference Figure 5 as well as Figure 6As shown, the positioning unit 30 includes a positioning laser 31, a video recording component 32, and a three-dimensional imaging component 33. The positioning laser 31 is used to generate positioning laser light, the video recording component 32 is used to record the skull surgery simulation operation process, and the three-dimensional imaging component 33 is used to collect image information of the skull model 10. In the embodiment provided in this application, the positioning laser 31 can generate positioning laser light to determine the placement and orientation of the skull model 10 relative to the positioning unit 30. The routing component can record the surgical simulation operation process in real time so that after the surgical simulation is completed, medical staff can review the entire surgical simulation process and conduct subsequent teaching. The video recording component 32 includes a color camera, or it can be a monochrome camera. The three-dimensional imaging component 33 can simultaneously collect image information of the skull model 10 from different angles and establish three-dimensional geometric information of the skull model 10 based on the image information and visual difference. The three-dimensional imaging component 33 includes a binocular vision camera, a monocular vision camera, or a multi-camera other than a binocular vision camera.

[0050] In a feasible embodiment, the positioning part 30 further includes a marking point (not shown in the figure), which is set on the surgical instrument. The marking point of the skull surgery simulation training of the present application is set at the position where the surgical instrument contacts the skull model 10.

[0051] Furthermore, the positioning unit 30 also includes positioning software (not shown), an output port 34, a power supply 35, and a display unit (not shown). When medical personnel use surgical instruments with marked points to perform a simulated surgical operation within the imaging range of the three-dimensional imaging unit 33, the positioning software tracks and locates the position of the surgical instruments with marked points in real time, guiding the surgical instruments to the target position on the skull model 10, thereby improving the efficiency of the surgical simulation. The output port 34 of the positioning unit 30 is connected to the display unit via a data transmission line, and displays a playback of the simulated surgical operation process based on the three-dimensional geometric information generated by the three-dimensional imaging unit 33; or based on the simulated surgical operation process recorded by the video recording unit 32. The display unit can be an electronic device such as a computer monitor, tablet, or mobile phone, and the display unit can communicate with the positioning unit 30 via a wireless connection, such as Wi-Fi or Bluetooth.

[0052] Reference Figure 3As shown, the skull surgery simulator further includes an adjustment rod 40, one end of which is connected to the tray 21, and the other end of which is connected to the positioning portion 30. The adjustment rod 40 is used to adjust the relative position between the positioning portion 30 and the fixing seat 20. During the manual simulation process, when performing surgical simulations for different tissue structures, the position between the fixing seat 20 and the positioning portion 30 needs to be adjusted. Therefore, the tray 21 and the positioning portion 30 are connected via the adjustment rod 40, and the relative position between the fixing seat 20 and the positioning portion 30 can be adjusted according to the needs of the surgical simulation training.

[0053] Reference Figure 7 As shown, the skull surgery simulation device also includes a cleaning part 50, which includes a first liquid storage bottle 51, a second liquid storage bottle 52, a suction tube 53, a water outlet pipe 54, a suction pump, a water outlet pump, a negative pressure regulating component 55 and a negative pressure gauge 56, wherein: the suction pump is arranged in the first liquid storage bottle 51, the suction pump is connected to the negative pressure regulating component 55 and the negative pressure gauge 56, and one end of the suction tube 53 is connected to the suction pump; the water outlet pump is arranged in the second liquid storage bottle 52, and one end of the water outlet pipe 54 is connected to the water outlet pump.

[0054] In the embodiment provided in the present application, the first liquid storage bottle 51 is used to store waste liquid generated after flushing, and the second liquid storage bottle 52 is used to store liquid used to flush model waste during the surgical simulation process. During the flushing process, the outlet pipe 54, under the action of the water outlet pump (not shown in the figure), sucks out the liquid in the second liquid storage bottle 52 and flushes it to the area where the model waste exists in the skull model 10. During the flushing process, the suction tube 53, under the action of the suction pump (not shown in the figure), recovers the waste generated by flushing and stores it in the first liquid storage bottle 51. The negative pressure regulating member 55 can adjust the suction pressure of the suction tube 53, and the negative pressure gauge 56 is used to measure and display the real-time pressure of the suction tube 53.

[0055] Reference Figure 8 As shown, the skull surgery simulation device also includes a power unit 60, which includes a grinding device 61, a speed adjustment member 62, a steering adjustment member 63 and a power switch, wherein: the speed adjustment member 62 is used to adjust the speed of the grinding device 61, the steering adjustment member 63 is used to adjust the steering of the grinding device 61, and the power switch is used to control the opening or closing of the power unit 60.

[0056] In the embodiment provided herein, the grinding device 61 comprises a grinding drill, primarily used for grinding the skull model 10. A speed regulator 62, a steering regulator 63, and a power switch provide driving force for the grinding device 61 to rotate at high speed to grind the target location of the skull model 10. The speed regulator 62 is used to adjust the speed of the grinding device 61, and the steering regulator 63 is used to adjust the forward or reverse rotation of the grinding device 61. The power switch comprises a manual switch 64 and a foot switch 65. During the surgical simulation, medical personnel can use the manual switch 64 or the foot switch 65 to control the operation or pause of the power unit 60.
