Description

Technical Field

[0001] This invention belongs to the field of medical teaching equipment technology, and in particular relates to a training device for medical clinical skills training. Background Technology

[0002] To improve the skills of medical staff, they need to undergo clinical skills training on a daily basis. This is especially important for medical staff with less clinical experience, as improving their clinical skills is key to effectively ensuring medical safety.

[0003] With the development of technology, displaying images of different diseases through display instruments can provide medical staff with clinical skills training for various diseases, greatly improving the effectiveness of skills training. For example, a training device for medical clinical skills training disclosed in patent publication number CN218038312U uses a camera to capture treatment images, and the corresponding image data can be played back for medical staff to conduct skills training. However, although playing image data through a monitor can help medical staff become familiar with disease information, the effect of strengthening practical skills through visual viewing alone is limited. Secondly, although making models can facilitate practical training, the number of diseases simulated by a single model is limited, the scope of application is small, and the training effect is not good. Summary of the Invention

The detection end of the pressure sensor is in contact with the bottom of the support block, and the pressure sensor is electrically connected to the computer control cabinet.

[0011] Preferably, the universal connection mechanism includes a triangular block fixed to the top of the support block, a connecting plate fixed to the side wall of the triangular block, a universal ball rotatably connected to the side wall of the connecting plate, a connecting groove on the ball wall of the universal ball, and a detachable handle fixed inside the connecting groove.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1-7As shown, a training device for medical clinical skills training includes a training table 1 and a computer control cabinet 2 mounted on the upper surface of the training table 1. The training table 1 has mounting holes on its end face, and a display 3 is fixed within the mounting holes. The device also includes a movable plate 4, positioned above the training table 1. The movable plate 4 is equipped with a first moving mechanism 5, and the movable plate 4 is connected to the training table 1 via the first moving mechanism 5. A horizontal sliding hole 6 is provided at the top of the movable plate 4. The first moving mechanism 5 includes first guide wheel assemblies 51 fixed to both sides of the bottom of the movable plate 4. The upper surface of the training platform 1 has guide rail grooves 52 on both sides that match the first guide rail wheel assembly 51. The side walls of the two opposite sides of the first guide rail wheel assembly 51 are fixed with first electromagnetic blocks 53. The groove walls of the guide rail grooves 52 are fixedly embedded with first iron bars 54 corresponding to the positions of the first electromagnetic blocks 53. The first electromagnetic blocks 53 are electrically connected to the computer control cabinet 2. The training platform 1 is equipped with a longitudinal position monitoring component 12. The training platform 1, the first guide rail wheel assembly 51 and other components are all made of non-magnetic materials to avoid being affected by the magnetic force of the first electromagnetic blocks 53.

[0020] The longitudinal position monitoring component 12 includes a first side plate 121 fixed to one side of the upper surface of the training table 1, and a first infrared ranging probe 122 electrically connected to the computer control cabinet 2 is fixedly inserted into the side wall of the first side plate 121. A first positioning post 123 coaxial with the first infrared ranging probe 122 is fixed to the side wall of the universal connection mechanism 11. The first infrared ranging probe 122 emits an infrared beam, which is reflected by the first positioning post 123 to the receiving end of the first infrared ranging probe 122. The position of the moving plate 4 can be calculated by calculating the time difference between emitting the infrared beam and receiving the reflected infrared beam.

[0021] The movable block 7 is slidably disposed inside the transverse hole 6. The movable block 7 is equipped with a second moving mechanism 8 and is connected to the transverse hole 6 through the second moving mechanism 8. The second moving mechanism 8 includes a guide rail 81 fixed inside the transverse hole 6. A through hole is opened on the side wall of the movable block 7, and a second guide wheel assembly 82 matching the guide rail 81 is fixed inside the through hole. A second electromagnetic block 83 is fixed on the side wall of the two opposite sides of the second guide wheel assembly 82. Two second iron bars 84 corresponding to the positions of the second electromagnetic blocks 83 are fixedly embedded in the hole wall of the transverse hole 6. The second electromagnetic blocks 83 are electrically connected to the computer control cabinet 2. The movable plate 4 is equipped with a transverse position monitoring component 13. The movable block 7, the second guide wheel assembly 82 and other components are all made of non-magnetic materials to avoid being affected by the magnetic force of the second electromagnetic blocks 83.

[0022] The lateral position monitoring component 13 includes a second side plate 131 fixed to one side of the top of the moving plate 4, and a second infrared ranging probe 132 electrically connected to the computer control cabinet 2 is fixedly inserted into the side wall of the second side plate 131. A second positioning post 133 coaxial with the second infrared ranging probe 132 is fixed to the side wall of the universal connection mechanism 11. The second infrared ranging probe 132 emits an infrared beam, which is reflected by the second positioning post 133 to the receiving end of the second infrared ranging probe 132.

The detection end of the pressure sensor 93 is in contact with the bottom of the support block 91. The pressure sensor 93 is electrically connected to the computer control cabinet 2. The pressure sensor 93 can convert pressure into an electrical signal and feed it back to the computer control cabinet 2.

[0024] The mounting handle 10 is positioned above the movable block 7. The mounting handle 10 is equipped with a universal connection mechanism 11 and is connected to the pressure support assembly 9 via the universal connection mechanism 11. The universal connection mechanism 11 includes a triangular block 111 fixed to the top of the support block 91. A connecting plate 112 is fixed to the side wall of the triangular block 111.

A connecting groove 114 is provided on the ball wall of the universal ball 113, and the mounting handle 10 is detachably fixed inside the connecting groove 114. A ball groove matching the universal ball 113 is provided on the side wall of the triangular block 111, and a deflection monitoring assembly 14 is provided inside the ball groove. The first positioning post 123 and the second positioning post 133 are both fixed to the side wall of the triangular block 111. A rubber damping strip is provided at the rotatable connection between the connecting plate 112 and the universal ball 113 to prevent the universal ball 113 from rotating arbitrarily.

[0025] The deflection monitoring component 14 includes a laser lamp 141 fixed inside the connecting groove 114. An incident light hole 142 is opened at the bottom of the connecting groove 114. A beam splitter 143 is fixed at the bottom of the incident light hole 142. Two exit light holes 144 are opened on the wall of the omnidirectional ball 113, which are connected to the incident light hole 142. The beam emitted by the laser lamp 141 is refracted into the two exit light holes 144 by the beam splitter 143. A photodiode array 145 is fixed inside the wall of the spherical groove. Both the laser lamp 141 and the photodiode array 145 are electrically connected to the computer control cabinet 2. The photodiode array 145 includes multiple photodiodes. After receiving the laser beam, the photodiodes will feed back an electrical signal to the computer control cabinet 2.

[0026] The operating principle of the present invention is explained as follows: A corresponding simulation device (a simulation device is a device that matches the handle shape, weight, etc. of the actual device) is installed on the mounting handle 10. Then, the corresponding symptom data is selected through the computer control cabinet 2, and the corresponding symptom image information is played on the display 3. At the same time, a virtual device corresponding to the simulation device is displayed on the display 3. Then, the trainee holds the simulation device installed on the mounting handle 10 and can start training. During training, trainees can use a simulator to drive the moving block 7 to move horizontally along the transverse sliding hole 6 of the moving plate 4, or drive the moving plate 4 to move horizontally along the training platform 1. When the moving plate 4 moves horizontally, the first infrared ranging probe 122 continuously emits infrared beams. After the infrared beams are reflected by the first positioning post 123 to the receiving end of the first infrared ranging probe 122, the first infrared ranging probe 122 will send corresponding electrical signals back to the computer control cabinet 2. By calculating the time difference between the emission and reception of the infrared beams, the longitudinal movement distance of the moving plate 4 can be determined. Similarly, the second... The infrared ranging probe 132 and the second positioning post 133 can measure the horizontal lateral movement distance of the moving block 7. The computer control cabinet 2 constructs the real-time coordinates of the operation point and forms continuous operation trajectory data based on the movement position information of the moving plate 4 and the moving block 7. Based on the coordinate mapping relationship between the trajectory data and the preset surgical path, the computer control cabinet 2 controls the virtual instruments on the display 3 to move synchronously. At the same time, if the movement position of the moving plate 4 or the moving block 7 exceeds the coordinate threshold range of the preset path, the computer control cabinet 2 will automatically record the coordinates and time information of the deviation point and issue sound and light prompts to remind of the operation deviation. To improve the simulation effect, the computer control cabinet 2 controls the first electromagnetic block 53 and the second electromagnetic block 83 to work according to the preset program. When the first electromagnetic block 53 and the second electromagnetic block 83 are energized, they will generate magnetic attraction. The magnetic attraction between the first electromagnetic block 53 and the first iron bar 54 will increase the resistance when the moving plate 4 moves longitudinally, while the magnetic attraction between the second electromagnetic block 83 and the second iron bar 84 will increase the resistance when the moving block 7 moves horizontally. By adjusting the current supplied to the first electromagnetic block 53 and the second electromagnetic block 83, the resistance can be precisely controlled at multiple levels to adapt to the resistance requirements of different surgical scenarios such as soft tissue traction and bone tissue manipulation. This allows trainees to strengthen their operational control in gradient resistance training and further reproduce the resistance feedback texture of clinical practice. In actual clinical practice, some instruments require a certain amount of pressure to be applied during use, such as when a scalpel cuts the skin. Such operations require high precision in pressure control. During training, trainees can apply pressure to the support block 91 by using a simulated instrument with handle 10, universal ball 113, connecting plate 112, and triangular block 111. The detection end of the pressure sensor 93 will monitor the pressure on the support block 91 in real time and convert the pressure into an electrical signal to be fed back to the computer control cabinet 2. When the pressure applied by the trainee exceeds the preset threshold (this threshold is preset based on the operating pressure required for different diseases), the computer control cabinet 2 will record the corresponding pressure value and time point, and issue audible and visual prompts to remind the trainee of the operational deviation. Meanwhile, in actual clinical practice, some instruments require deflection at a certain angle during use, such as the intraoperative turning of laparoscopic grasping forceps. Such operations directly affect surgical accuracy. During training, trainees use a simulated instrument to deflect the mounting handle 10, which in turn deflects the universal ball 113. The laser lamp 141 inside the universal ball 113 emits a laser beam, which is refracted into two beams by the beam splitter 143. These two beams exit from corresponding exit holes 144, and two photodiodes in the photodiode array 145 receive the corresponding laser beams. When the universal ball 113 deflects, the two... The position of each light-emitting aperture 144 will also change synchronously. At this time, the position of the laser beam will also change. The photodiode array 145 receiving the laser beam will also change synchronously. Therefore, based on the position of the photodiode receiving the laser beam, the pitch angle and roll angle of the omnidirectional ball 113 can be accurately calculated, realizing real-time quantization of the deflection angle. At the same time, the computer control cabinet 2 will control the virtual device on the display 3 to deflect synchronously according to the deflection angle information. When the deflection angle exceeds the preset threshold, the computer control cabinet 2 will record the corresponding angle value and time node, and issue audible and visual prompts to remind of the operation deviation. After a single training session, trainees can view deviation information through computer control cabinet 2, which facilitates review of the training process and effectively improves training results.
