Description

Technical Field

[0001] This invention belongs to the field of surgical simulation training technology, specifically relating to an electromagnetic navigation endoscopic surgical path simulation training device. Background Technology

[0002] Electromagnetic navigation endoscopic surgery is a precision diagnostic and treatment technique that combines electromagnetic positioning technology, three-dimensional image reconstruction, and minimally invasive endoscopic manipulation. The electromagnetic navigation endoscopic surgery path simulation training equipment is used for operators to simulate electromagnetic navigation endoscopic surgery. It mainly consists of a machine, a monitor, an endoscope, and a human mannequin. During use, the endoscope is inserted into the human mannequin, and the captured images are displayed on the monitor for the operator to review.

[0003] Existing electromagnetic navigation endoscopic surgical path simulation training equipment generally lacks a support mechanism to support the operator's arm during use. Since operators are still in the simulation training stage and lack sufficient proficiency in electromagnetic navigation endoscopic surgery, they need to spend a considerable amount of time performing the procedure. Prolonged arm suspension can easily lead to fatigue, hindering training convenience. While some training equipment does have a support mechanism, this mechanism is merely a fixed support and cannot adapt to the arm height of operators of different heights, resulting in insufficient training applicability. Furthermore, the monitor height generally requires manual adjustment by the operator. When changing operators for training, the monitor height needs to be adjusted to accommodate the height differences between them, increasing manual adjustments with more frequent changes, further complicating training convenience. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic navigation endoscopic surgical path simulation training device that can adjust the height of the support frame as the operator's arm is pressed down, making it easy to adapt to the arm height of operators of different heights, thus improving the applicability of training. Furthermore, it can passively adjust the height of the display as the support frame moves down, avoiding the need for frequent manual adjustment of the display height when changing operators, making it easier to adapt to the height differences between different operators and improving the convenience of training.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An electromagnetic navigation endoscopic surgical path simulation training device includes a body, on which a display and a support frame are slidably connected along a vertical direction, and further includes:

[0007] An adjustment mechanism is provided on the machine body. The adjustment mechanism includes a worm gear and a worm shaft that are rotatably connected to the machine body. The worm gear and the worm shaft mesh with each other. The lower end of the display is threadedly connected to the worm gear. A stud is threadedly connected to the end of the support frame. The stud is rotatably connected to the machine body and is drivenly connected to the worm shaft. A return spring is connected between the bottom of the support frame and the machine body.

[0008] The support frame moves downward, causing the stud to rotate. The stud, through a worm and a worm wheel, causes the display to move downward.

[0009] A first bevel gear is fixedly connected to the stud, and a second bevel gear is fixedly connected to one end of the worm gear near the stud, with the first bevel gear meshing with the second bevel gear.

[0010] A screw is fixedly connected inside the worm gear. The lower end of the screw is rotatably connected to the machine body, and the upper end of the screw is threadedly connected to the lower end of the display.

[0011] The support frame has a threaded hole at one end near the machine body, and the threaded hole is threaded with a stud.

[0012] The lower end of the display is fixedly connected to a first slide bar, and a first slide groove is provided on the body. The first slide bar and the first slide groove slide together in a vertical direction.

[0013] A second slide bar is fixedly connected to one end of the support frame near the machine body. A second slide groove is provided on the machine body. The second slide bar and the second slide groove slide together in a vertical direction.

[0014] A drive motor is provided at the lower end of the stud, the output end of the drive motor is fixedly connected to the stud, and the drive motor is fixedly connected to the machine body.

[0015] The technical effects achieved by this utility model are as follows:

[0016] The support frame of this utility model adjusts its height position as the operator's arm presses down. Compared with the prior art, this reduces the fatigue caused by the operator's arm being suspended in the air for a long time, improves the convenience of training, and is easy to adapt to the arm height position of operators of different heights, thus improving the applicability of training.

[0017] The display in this invention passively adjusts its height as the support frame moves downward. Compared with the existing technology that requires operators to actively and manually adjust the height of the display, this avoids the need for frequent manual adjustments when changing operators. It is also easier to adapt to the height differences between different operators, making the height of the display closer to the height of the operator's eyes, thus improving the convenience of training.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, this is the first embodiment of the present invention. This first embodiment provides an electromagnetic navigation endoscopic surgical path simulation training device, including a body 10. A display 11 and a support frame 12 are slidably connected to the body 10 in the vertical direction. It also includes an adjustment mechanism 20, which is disposed on the body 10. The adjustment mechanism 20 includes a worm gear 21 and a worm 22 rotatably connected to the body 10. The worm gear 21 and the worm 22 are meshed. The lower end of the display 11 is threadedly connected to the worm gear 21. A stud 23 is threadedly connected to the end of the support frame 12. The stud 23 is rotatably connected to the body 10 and is drively connected to the worm 22. A return spring 24 is connected between the bottom of the support frame 12 and the body 10.

[0027] It should be noted that a bed is also provided on one side of the machine body 10. An electromagnetic positioning plate (not shown in the figure) is provided on the bed. The electromagnetic positioning plate is existing technology and is used to construct an electromagnetic field to track the position of the endoscope in real time. A human body model is provided on the bed. The human body model is existing technology. Several channels (not shown in the figure) are opened inside the human body model to simulate the trachea and bronchus. An endoscope (not shown in the figure) is provided on the machine body 10. The endoscope is existing technology and is used to insert into the human body model to take images. It will not be described in detail here. The display 11 is existing technology. The display 11 includes a display screen and a support column. The display screen and the support column are rotatably connected to adjust the orientation angle of the display screen so that the display 11 faces the side closer to the operator. The helix angle of the worm 22 is less than or equal to the equivalent friction angle of the meshing surface of the worm 22 and the worm wheel 21, so that the worm 22 and the worm wheel 21 have self-locking property. The worm 22 can drive the worm wheel 21, but the worm wheel 21 cannot drive the worm 22 in the opposite direction.

[0028] In this embodiment, the operator's arm is placed on the support frame 12. Under its own weight, the arm moves the support frame 12 downward, causing the return spring 24 to be compressed and its height reduced. As the support frame 12 moves downward along the stud 23, it also rotates the stud 23. The stud 23 drives the worm gear 22 to rotate, which in turn drives the worm wheel 21 to rotate. This causes the worm wheel 21 to move the display 11 downward, thus lowering both the height of the support frame 12 and the height of the display 11. Compared to existing methods without a support frame 12, this reduces operator fatigue caused by prolonged arm suspension, improving training convenience. Compared to the fixed support frame 12 in existing technologies, the lower the height of the arm is for shorter operators, making it more comfortable for them to place their arms. The height position reduces the need for shorter operators to raise their arms to place them on the fixed support frame 12, making it easier to adapt to the arm height positions of operators of different heights and improving the applicability of training. Compared with the existing technology that requires active manual adjustment of the height position of the display 11, the height position of the display 11 is passively adjusted according to the height position of the support frame 12. After a shorter operator places their arm, the height position of the support frame 12 decreases, and the height position of the display 11 also decreases, bringing the height position of the display 11 closer to the eye level of the operator. This reduces the need for shorter operators to look up at the display 11, adapts to the height differences between different operators, avoids the need for frequent manual adjustment of the height position of the display 11 when changing operators, and improves the convenience of training.

[0029] When a reset is required, the operator moves their arm away from the support frame 12, so that the arm no longer presses down on the support frame 12. The reset spring 24 pushes the support frame 12 upward under the elastic action, so that the support frame 12 is reset. While the support frame 12 moves upward along the stud 23, it also drives the display 11 upward through the worm 22 and worm wheel 21, so that the display 11 is reset, which is convenient for the next operator to conduct simulation training. Moreover, since the worm wheel 21 and worm 22 have self-locking properties, it prevents the display 11 from moving downward under its own gravity after being reset.

[0030] like Figure 3 and Figure 4 As shown, a first bevel gear 31 is fixedly connected to the stud 23, and a second bevel gear 32 is fixedly connected to one end of the worm gear 22 near the stud 23. The first bevel gear 31 and the second bevel gear 32 mesh with each other.

[0031] It should be noted that the stud 23 and the worm 22 are connected by a first bevel gear 31 and a second bevel gear 32.

[0032] In this embodiment, the stud 23 rotates, which drives the first bevel gear 31 to rotate. The first bevel gear 31 rotates, which drives the second bevel gear 32 to rotate. The second bevel gear 32 rotates, which drives the worm gear 22 to rotate, thus facilitating the rotation of the stud 23 to drive the worm gear 22 to rotate.

[0033] like Figure 3 and Figure 4 As shown, a screw 33 is fixedly connected inside the worm gear 21. The lower end of the screw 33 is rotatably connected to the machine body 10, and the upper end of the screw 33 is threadedly connected to the lower end of the display 11.

[0034] It should be noted that the screw 33 passes through the inside of the worm gear 21, and the screw 33 and the worm gear 21 are interference-fitted. The lower end of the screw 33 is rotatably connected to the machine body 10 through a bearing (not shown in the figure). The lower end of the display 11 is provided with an internal thread, and the upper end of the screw 33 is provided with an external thread. The internal thread and the external thread are threadedly fitted.

[0035] In this embodiment, the worm gear 21 is rotatably connected to the machine body 10 via the screw 33. After the worm gear 21 rotates, it drives the screw 33 to rotate, so that while the lower end of the display 11 rotates relative to the screw 33, the lower end of the display 11 also moves up and down along the screw 33, thereby facilitating the up and down movement of the display 11 after the worm gear 21 rotates.

[0036] like Figure 3 and Figure 4 As shown, the support frame 12 has a threaded hole 35 at one end near the body 10, and the threaded hole 35 is threadedly engaged with the stud 23.

[0037] It should be noted that the end of the support frame 12 is threadedly connected to the stud 23 through the threaded hole 35.

[0038] In this embodiment, the threaded hole 35 cooperates with the stud 23, so that after the support frame 12 moves up and down along the stud 23, it drives the stud 23 to rotate through the threaded hole 35, thereby facilitating the rotation of the stud 23 after the support frame 12 moves.

[0039] like Figure 3 and Figure 4 As shown, a first slide bar 36 is fixedly connected to the lower end of the display 11, and a first slide groove 37 is provided on the body 10. The first slide bar 36 and the first slide groove 37 slide in a vertical direction.

[0040] It should be noted that the cross-sectional shape of the first slider 36 and the first groove 37 is rectangular.

[0041] In this embodiment, the first slide bar 36 cooperates with the first slide groove 37, making the process of the display 11 moving up and down along the body 10 more stable.

[0042] like Figure 3 and Figure 4 As shown, a second slide bar 38 is fixedly connected to one end of the support frame 12 near the body 10, and a second slide groove 39 is provided on the body 10. The second slide bar 38 and the second slide groove 39 slide in a vertical direction.

[0043] It should be noted that the cross-sectional shape of the second slide bar 38 and the second slide groove 39 is dovetail-shaped or "T"-shaped, and the dovetail shape is preferred in this utility model.

[0044] In this embodiment, the second slide bar 38 and the second slide groove 39 cooperate to make the process of the support frame 12 sliding along the body 10 more stable.

[0045] Example 2

[0046] Reference Figure 4 This is the second embodiment of the present invention. This second embodiment is based on the previous embodiment, but the difference is that: a drive motor 34 is provided at the lower end of the stud 23, the output end of the drive motor 34 is fixedly connected to the stud 23, and the drive motor 34 is fixedly connected to the body 10.

[0047] It should be noted that the drive motor 34 in this utility model is preferably a motor with self-locking function and forward and reverse rotation function. A switch (not shown in the figure) is connected to the drive motor 34 by a wire. The switch is existing technology and is used to control the start, stop and forward and reverse rotation of the drive motor 34, which will not be described in detail here.

[0048] In this embodiment, the operator's arm is placed on the support frame 12. After the drive motor 34 is working, its output end drives the stud 23 to rotate. The stud 23 drives the support frame 12 to move up and down to adjust the height position of the support frame 12, thereby adjusting the height position of the operator's arm. When the support frame 12 moves to a suitable height position, the drive motor 34 stops working, so that the support frame 12 is kept at a suitable height position. This not only supports the operator's arm through the support frame 12, reducing the fatigue that can easily occur when the operator's arm is suspended in the air for a long time, but also adapts to the arm height position corresponding to operators of different heights, improving applicability.

[0049] The working principle of this utility model is as follows: After the operator's arm is placed on the support frame 12, the support frame 12 supports the arm, reducing the time the arm is suspended in the air. When the arm presses down on the support frame 12, the height of the support frame 12 is lowered. When a shorter person presses down on the support frame 12, the height of the support frame 12 is lowered, making it easier to adapt to the arm height of operators of different heights, thus improving the applicability of training. Furthermore, after the support frame 12 moves downward, it also moves the display 11 downward through the adjustment mechanism 20, thus lowering the height of the display 11. When a shorter person presses down on the support frame 12, the height of the display 11 is lowered, making it easier to adapt to the eye height of operators of different heights, thus avoiding the need for frequent manual adjustment of the height of the display 11 when changing operators, and improving the convenience of training.

[0050] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
