[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the design of the dissection table, H-shaped frame, display, lighting projection mechanism, covering mechanism and instrument placement mechanism, when conducting dissection teaching, the lighting projection mechanism and covering mechanism can be activated, and the lighting projection mechanism will rise from the H-shaped frame so that both the irradiation end and the projection end face the upper surface of the dissection table. When the covering mechanism is activated, the display will be unfolded so that the image illuminated by the projection end of the lighting projection mechanism can be projected on the display for students to watch and learn. This interactive display method can enhance students' learning experience, make the dissection process clearer and more vivid, and enable teachers to adjust the display content at any time according to students' feedback, which can greatly improve the students' learning experience. It can enhance students' learning interest and participation. Later, when performing anatomical operations, teachers can adjust the steering angle of the instrument placement mechanism according to their usage habits and push the entire instrument placement mechanism to slide to a suitable position in the sliding groove to pick up and place anatomical tools. The sliding of the instrument placement mechanism in the sliding groove can make the skull base anatomical instruments move and adjust with the teacher's anatomical position, so that teachers can adjust the steering angle of the instrument placement mechanism according to their own usage habits, and thus teachers do not need to overstretch or bend their bodies to pick up anatomical tools, which reduces physical exertion and operation time during the operation and improves the efficiency of anatomical operations.

[0019] 2. Through the design of the sliding block, connecting block, turntable and tray, during the dissection operation, the teacher can adjust the angle of the tray on the outer surface of the sliding block according to the usage habits. After the angle is rotated, the teacher can press the turntable thread on the upper surface of the connecting block by twisting the turntable thread, and tighten the turntable thread into the sliding block, so as to lock the rotation force of the tray after the angle is adjusted. This ensures that the angle of the tray will not change due to accidental collision or slight vibration during use, ensures the stability of the dissection tools when placed on the tray, and prevents the tools from slipping or shifting;

[0020] And according to the anatomical position, the tray can be pushed or pulled to slide horizontally in the sliding groove through the sliding block, so that the tray can be slid to a suitable position for the teacher to take and place the anatomical tools. In the process of dissection, the anatomical part may change continuously. This sliding function can ensure that the teacher can easily obtain the required tools without moving the body significantly, saving time in the dissection operation and improving the efficiency of the dissection operation.

[0021] 3. Through the design of the linear module, connecting arm, mounting block, lighting, camera and electric push rod, during the dissection work, the linear module can be started to drive the connecting arm at one end of the moving block to rise, and then the connecting arm can drive the mounting block between them to rise out of the H-shaped frame, and then the electric push rod can be started to push the mounting block at one end of the piston rod to rotate on the outer surface of the connecting arm, and then the mounting block can drive the lighting and three sets of cameras to face the upper surface of the dissection table, thereby ensuring that the lighting provides the best lighting angle, making the dissection area clearly visible, avoiding shadows interfering with the dissection operation, and improving the visibility of the dissection work At the same time, the three groups of cameras can accurately capture the images on the dissection table and capture the images of the three areas of the head and neck, trunk and lower limbs, which are projected on the display and presented in three windows in sequence, which helps to fully record the dissection process. For teaching, students can see the anatomical conditions of different areas at the same time, which helps to establish an overall anatomical knowledge system, and can completely record the anatomical data, which is convenient for subsequent analysis and review, and also convenient for teachers to make comparative explanations. For example, the structural differences between the head and neck and the trunk, or the muscle connection relationship between the lower limbs and the trunk can be explained at the same time, thereby improving teaching efficiency.

[0022] 4. Through the design of the double-axis motor, the first transmission column, the long strip, the protective belt, the second transmission column, the torsion spring and the connecting tube, when the display in the H-shaped frame is unfolded, the double-axis motor can be started to drive the two sets of first transmission columns to deliver the long strip, thereby releasing the torsion force on the second transmission column, so that the second transmission column can simultaneously reel in the protective belt through the torsion force applied by the torsion spring, thereby moving the protective belt away from the display to unfold the display;

[0023] After the anatomical teaching is completed, the dual-axis motor can be started to drive the first transmission column to reel in the long strip, so that the long strip can pull the protective belt from the outer surface of the second transmission column, and then the second transmission column can be driven to twist the twisting spring in the connecting tube, and the twisting spring can apply a torsional force to the second transmission column. At the same time, the stretched protective belt can cover the display inside, thereby preventing dust, liquid and other pollutants from contacting the display, thereby protecting the display screen, extending its service life, and reducing display failures caused by pollution. This automatic covering and revealing mechanism enables the display to be quickly exposed for use during the anatomical teaching process, and can be covered in time after the teaching is completed, thereby improving the convenience and efficiency of the use of the entire anatomical teaching facility.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 8 , this embodiment provides the following technical solutions:

[0035] like Figure 1-Figure 4 As shown, a skull base anatomy teaching instrument comprises: a dissecting table 1, a sliding groove 103 is provided at one end of the dissecting table 1, and an instrument placement mechanism 5 is slidably installed in the sliding groove 103, so that the instrument placement mechanism 5 can be pushed and pulled by the teacher to slide on one side of the dissecting table 1 so as to move the skull base dissecting instrument following the teacher;

[0036] An H-shaped frame 101 is fixedly installed at one end of the dissecting table 1, and a covering mechanism 4 is fixedly installed at one end of the H-shaped frame 101. The covering end of the covering mechanism 4 slides through the sliding strip opening 2 and covers the outer surface of the display 102. The sliding strip opening 2 is opened on both sides of the H-shaped frame 101, and the display 102 is fixedly installed at the other end of the H-shaped frame 101.

[0037] Among them, a lighting and projection mechanism 3 is fixedly installed at one end of the H-shaped frame 101, and the lighting and projection mechanism 3 is located between the covering mechanisms 4. The lighting and projection mechanism 3 can be slid out from the H-shaped frame 101 to illuminate the upper surface of the dissecting table 1.

[0038] Through the design of the dissecting table 1, the H-shaped frame 101, the display 102, the lighting projection mechanism 3, the covering mechanism 4 and the instrument placement mechanism 5, when conducting dissecting teaching, the lighting projection mechanism 3 and the covering mechanism 4 can be activated, and the lighting projection mechanism 3 will rise from the H-shaped frame 101 so that the irradiation end and the projection end are both facing the upper surface of the dissecting table 1, and the activation of the covering mechanism 4 will unfold the display 102 so that the picture illuminated by the projection end of the lighting projection mechanism 3 is projected on the display 102 for students to watch and learn. This interactive display method can enhance the students' learning experience, make the dissecting process clearer and more vivid, and enable the teacher to adjust the display at any time according to the students' feedback. This can greatly enhance students' interest in learning and participation. Later, when performing anatomical operations, teachers can adjust the steering angle of the instrument placement mechanism 5 according to their usage habits and push the entire instrument placement mechanism 5 to slide to a suitable position in the sliding groove 103 to pick up and place anatomical tools. The sliding of the instrument placement mechanism 5 in the sliding groove 103 can enable the skull base anatomical tools to move and adjust the anatomical position following the teacher, so that the teacher can adjust the steering angle of the instrument placement mechanism 5 according to his or her own usage habits, thereby eliminating the need for the teacher to overstretch or bend the body to pick up anatomical tools, reducing physical exertion and operation time during the operation and improving the efficiency of the anatomical operation.

[0039] like Figure 5 As shown, the instrument placement mechanism 5 includes a sliding block 501, which is fixedly installed in the sliding groove 103. A connecting block 502 is rotatably installed on the outer surface of the sliding block 501, and a tray 504 is fixedly installed at one end of the connecting block 502, so that the tray 504 can be pushed and pulled by the teacher to slide in the sliding groove 103 through the sliding block 501, so as to follow the movement of the teacher to facilitate the taking and placement of skull base dissection instruments.

[0040] A turntable 503 is threadedly mounted on the upper surface of the connecting block 502 , so that the threaded portion of the turntable 503 is screwed into the sliding block 501 , thereby driving the handle of the turntable 503 to press against the upper surface of the connecting block 502 to apply a locking force to the rotation of the tray 504 .

[0041] Through the design of the sliding block 501, the connecting block 502, the turntable 503 and the tray 504, during the dissection operation, the teacher can adjust the angle of the tray 504 on the outer surface of the sliding block 501 according to the usage habits. After the angle is rotated, the teacher can press the thread of the turntable 503 against the upper surface of the connecting block 502 by twisting the thread, and tighten the thread of the turntable 503 into the sliding block 501, so as to lock the rotation force of the tray 504 after the angle is adjusted. This ensures that the angle of the tray 504 will not change due to accidental collision or slight vibration during use, ensures the stability of the dissection tools when placed on the tray 504, and prevents the tools from slipping or shifting.

[0042] Furthermore, the tray 504 can be pushed or pulled to slide horizontally in the sliding groove 103 through the sliding block 501 according to the anatomical position, so that the tray 504 can slide to a suitable position for the teacher to take and place the anatomical tools. According to the anatomical position, the tray 504 can be pushed or pulled to slide horizontally in the sliding groove 103 to reach a suitable position for the teacher to take and place the anatomical tools. During the anatomical process, the anatomical part may change continuously. This sliding function can ensure that the teacher can easily obtain the required tools without moving the body significantly, saving time in the anatomical operation and improving the efficiency of the anatomical operation.

[0043] like Figure 6-Figure 7 As shown, the lighting projection mechanism 3 includes two groups of linear modules 301, and the two groups of linear modules 301 are fixedly installed at one end of the H-shaped frame 101. A connecting arm 302 is fixedly installed at one end of the moving block of the two groups of linear modules 301. A mounting block 305 is rotatably installed on the upper surface between the two groups of connecting arms 302. The lower half of one end of the mounting block 305 is in an embedded valve type and fixedly installed with multiple groups of lighting lamps 306.

[0044] The mounting block 305 can be pushed out of the H-shaped frame 101 by the two sets of linear modules 301 through the connecting arm 302 , so that the mounting block 305 drives the lighting lamp 306 to illuminate the upper surface of the dissecting table 1 .

[0045] Three groups of cameras 307 are embedded at one end of the mounting block 305, and the three groups of cameras 307 are connected to the display 102 via the USB output port. The lenses of the three groups of cameras 307 face the three segments on the upper surface of the dissecting table 1 respectively, that is, they can illuminate the head and neck, trunk and lower limbs of the human body, so that the cameras 307 project the head and neck, trunk and lower limbs onto the display 102 and present them in three windows arranged in sequence.

[0046] A connecting plate 303 is fixedly installed between the two groups of connecting arms 302, and an electric push rod 304 is rotatably installed on the upper surface of the connecting plate 303. The piston rod of the electric push rod 304 is rotatably installed in the docking plate 308, and the docking plate 308 is fixedly installed on the lower half of one end of the mounting block 305, so that the mounting block 305 can be tilted and rotated at the outer surface of the two groups of connecting arms 302 through the push and pull of the electric push rod 304.

[0047] Through the design of the linear module 301, the connecting arm 302, the mounting block 305, the lighting lamp 306, the camera 307 and the electric push rod 304, during the dissection work, the linear module 301 can be started to drive the connecting arm 302 at one end of the moving block to rise, so that the connecting arm 302 can drive the mounting block 305 between them to rise out of the H-shaped frame 101, and then the electric push rod 304 can be started to push the mounting block 305 at one end of the piston rod to rotate at an angle on the outer surface of the connecting arm 302, so that the mounting block 305 can drive the lighting lamp 306 and the three groups of cameras 307 to face the upper surface of the dissection table 1, thereby ensuring that the lighting lamp 306 provides the best lighting angle to make the dissection area clear. It can be seen that shadows are avoided from interfering with the anatomical operation, the visibility of the anatomical work is improved, and at the same time, the three groups of cameras 307 can accurately capture the images on the anatomical table 1 and capture the images of the three areas of the head and neck, trunk and lower limbs, which are projected on the display 102 and presented in three windows in sequence, which helps to fully record the anatomical process. For teaching, students can see the anatomical conditions of different areas at the same time, which helps to establish an overall anatomical knowledge system, and can completely record the anatomical data, which is convenient for subsequent analysis and review, and can also facilitate teachers to conduct comparative explanations. For example, the structural differences between the head and neck and the trunk, or the muscle connection relationship between the lower limbs and the trunk, etc. can be explained at the same time, thereby improving teaching efficiency.

[0048] like Figure 8 As shown, the covering mechanism 4 includes a first transmission column 402 and a second transmission column 405. The first transmission column 402 is two groups fixedly mounted on the upper and lower surfaces of the output shaft of the double-axis motor 401, and the double-axis motor 401 is fixedly mounted in the H-shaped frame 101. The second transmission column 405 is rotatably mounted between two groups of connecting cylinders 407. The two groups of connecting cylinders 407 are fixedly mounted on the upper and lower surfaces of one end of the H-shaped frame 101.

[0049] The outer surfaces of the two sets of first transmission columns 402 are rolled up with long strips 403, and the outer surfaces of the second transmission columns 405 are rolled up with protective strips 404. The two sets of long strips 403 and protective strips 404 are slid through the slide opening 2 and are located on the other side of the H-shaped frame 101 and are connected. When the dual-axis motor 401 drives the two sets of first transmission columns 402 to roll up the long strips 403, the long strips 403 can pull the protective strips 404 to cover the outer surface of the display 102.

[0050] When the dual-axis motor 401 releases the long strips 403 , the second transmission column 405 can reel in the protection strips 404 to unfold the display 102 and position the two groups of long strips 403 at the upper and lower ends of the display 102 .

[0051] When the first transmission column 402 and the second transmission column 405 wind up or loosen the long belt 403 and the protective belt 404, the long belt 403 and the protective belt 404 can be pressed against the outer surface of the transmission wheel 104 for transportation. The transmission wheel 104 is rotatably installed at the four corners of one end of the H-shaped frame 101, so that the long belt 403 and the protective belt 404 are supported by the transmission of the transmission wheel 104, and the long belt 403 and the protective belt 404 can be suspended at one end of the display 102 without contacting the display 102.

[0052] The two sets of connecting tubes 407 are both fixedly connected with a torsion spring 406 , and the other end of the torsion spring 406 is fixedly connected to the outer surface of the second transmission column 405 , so that the torsion spring 406 can apply a resetting rotational winding force to the second transmission column 405 .

[0053] Through the design of the double-axis motor 401, the first transmission column 402, the long strip 403, the protective belt 404, the second transmission column 405, the torsion spring 406 and the connecting tube 407, when the display 102 in the H-shaped frame 101 is unfolded, the double-axis motor 401 can be started to drive the two groups of first transmission columns 402 to deliver the long strip 403, thereby releasing the torsion force on the second transmission column 405, so that the second transmission column 405 can simultaneously reel in the protective belt 404 through the torsion force applied by the torsion spring 406, thereby moving the protective belt 404 away from the display 102 to unfold the display 102;

[0054] After the anatomical teaching is completed, the dual-axis motor 401 can be started to drive the first transmission column 402 to reel in the long strip 403, so that the long strip 403 can pull the protective belt 404 from the outer surface of the second transmission column 405, and then the second transmission column 405 can be driven to twist the twisting spring 406 in the connecting tube 407, and the twisting spring 406 can apply a twisting force to the second transmission column 405. At the same time, the stretched out protective belt 404 can cover the display 102, thereby preventing dust, liquid and other pollutants from contacting the display 102, thereby protecting the screen of the display 102, extending its service life, and reducing display failures caused by pollution. This automatic covering and revealing mechanism enables the display 102 to be quickly revealed for use during the anatomical teaching process, and can be covered in time after the teaching is completed, thereby improving the convenience and efficiency of the use of the entire anatomical teaching facility.

[0055] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when conducting anatomical teaching, the linear module 301 and the dual-axis motor 401 can be started at the same time, and the linear module 301 will drive the connecting arm 302 at one end of the moving block to rise, so that the connecting arm 302 can drive the mounting block 305 between them to rise out of the H-shaped frame 101, and then the electric push rod 304 can be started to push the mounting block 305 at one end of the piston rod to rotate at an angle on the outer surface of the connecting arm 302, so that the mounting block 305 can drive the lighting lamp 306 and the three groups of cameras 307 to face the upper surface of the dissection table 1, thereby ensuring that the lighting lamp 306 provides the best lighting angle, making the dissection area clearly visible, avoiding shadows interfering with the dissection operation, and improving the dissection work. The three cameras 307 can accurately capture the images on the dissecting table 1 and the images of the three areas of the head and neck, trunk and lower limbs, which are projected on the display 102 and presented in three windows in sequence. The dual-axis motor 401 will drive the two first transmission columns 402 to release the long strip 403, thereby releasing the torsional force on the second transmission column 405, so that the second transmission column 405 can reel in the protective belt 404 by twisting the torsional force applied by the spring 406, and then the protective belt 404 can be moved away from the display 102 to display the display 102, so that students can see the anatomical conditions of different areas at the same time, which is helpful to establish an overall anatomical knowledge system. During the dissection operation, the teacher The tray 504 can be adjusted to rotate at an angle on the outer surface of the sliding block 501 according to usage habits. After the angle is rotated, the teacher can press the thread of the turntable 503 against the upper surface of the connecting block 502 by twisting the thread, and tighten the thread of the turntable 503 into the sliding block 501, so as to lock the rotation force of the tray 504 after the angle is adjusted. This ensures that the angle of the tray 504 will not change due to accidental collision or slight vibration during use, ensures the stability of the anatomical tools placed on the tray 504, prevents the tools from slipping or shifting, and can also push or pull the tray 504 to slide horizontally in the sliding groove 103 through the sliding block 501 according to the anatomical position, so that the tray 504 can slide to a suitable The position is convenient for the teacher to take and place the anatomical tools, and the tray 504 is pushed or pulled to slide horizontally in the sliding groove 103 according to the anatomical position, so that it reaches a suitable position for taking and placing the anatomical tools. After the dissection is completed, the linear module 301 and the dual-axis motor 401 can be started again, so that the linear module 301 can store the lighting lamp 306 and the camera 307 in the mounting block 305 back into the H-shaped frame 101 to protect and dustproof them, and the dual-axis motor 401 will drive the first transmission column 402 to reel the long strip 403, so that the long strip 403 can pull the protective belt 404 to be stretched out from the outer surface of the second transmission column 405, and then the second transmission column 405 can be driven to twist the twist spring 406 in the connecting tube 407.The twisting spring 406 can apply a twisting force to the second transmission column 405, and the stretched protection belt 404 can cover the display 102, thereby preventing dust, liquid and other pollutants from contacting the display 102, thereby protecting the screen of the display 102 and extending its service life.

[0056] In summary: the skull base anatomy teaching instrument can divide the anatomical image into three areas: head and neck, trunk and lower limbs, and project the images onto the display 102 and present them in three windows in sequence, which helps to comprehensively record the anatomical process. For teaching, students can see the anatomical conditions of different areas at the same time, which helps to establish an overall anatomical knowledge system. During the dissection, the angle of rotation of the tray 504 on the outer surface of the sliding block 501 can be adjusted according to the teacher's own usage habits, which can adapt to the unique operating habits of each teacher and improve the comfort of the teacher during operation.
