[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0031] The present invention relates to a small rocker arm for a medical device panel, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, it includes:

[0032] In this embodiment, a base 4 is provided on the small rocker arm used for the medical device panel. The base 4 serves as the main body of this embodiment, providing mounting positions and fixing points for other components.

[0033] The base plate 5 is fixed in the base 4. The base plate 5 cooperates with the base 4 to enclose and protect the internal components. The base plate 5 also facilitates the installation of other components.

[0034] A dial 8 is fixedly connected inside the base 4. Manually turning the dial 8 allows input of operation commands. The rotation of the dial 8 will drive the magnet 6 to move, changing the relative position between the magnet 6 and the Hall PCB7. The Hall PCB7 converts the magnetic field change into an electrical signal, thereby converting the mechanical rotation of the dial 8 into an electrical signal output.

[0035] A torsion spring 3 is fixed in the base 4. The small rocker arm used for the medical device panel is reset by the torsion spring 3. When the upper wheel 1 of the dial wheel 8 is turned, the upper wheel 1 drives the lower wheel 2 of the dial wheel 8 to rotate together, while compressing or stretching the torsion spring 3. The magnet 6 moves with the rotation of the upper wheel 1 or the lower wheel 2, changing its relative position with the Hall PCB7. This causes the magnetic field of the Hall PCB7 to change. The Hall PCB7 converts the change in magnetic field into an electrical signal and transmits it to the external circuit for processing, thereby realizing the input function of the dial wheel 8. When the dial wheel 8 is released, the elastic force of the torsion spring 3 causes the dial wheel 8 to automatically reset to the initial position.

[0036] In this embodiment, a torsion spring 3 is fixed in the base 4, and the small rocker arm for the medical device panel is reset via the torsion spring 3. When the upper wheel 1 of the dial wheel 8 is turned, the upper wheel 1 drives the lower wheel 2 of the dial wheel 8 to rotate together, while compressing or stretching the torsion spring 3. The magnet 6 moves with the rotation of the upper wheel 1 or the lower wheel 2, changing its relative position with the Hall PCB7, causing a change in the magnetic field of the Hall PCB7. The Hall PCB7 converts the change in magnetic field into an electrical signal, which is transmitted to the external circuit for processing, thereby realizing the input function of the dial wheel 8. When the dial wheel 8 is released, the elastic force of the torsion spring 3 causes the dial wheel 8 to automatically reset to the initial position. The advantages of compact structure, reliable performance, and easy installation solve the problem that in existing technologies, medical personnel may cause the small joystick to deviate from its initial position due to tension or rapid operation. If the small joystick cannot be reset in time and accurately, it may lead to subsequent operational errors, thereby affecting the normal operation of medical equipment and the patient's treatment process. The small joysticks used in the market are mostly over 30mm in length and over 12mm in width, which occupy a large volume when used in related medical equipment. Their wiring method is usually wire harness wiring, which may have technical problems such as poor contact, poor soldering or plugging.

[0037] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the dial 8 includes:

[0038] The lower wheel 2 is fixedly connected inside the base 4. The lower wheel 2 works with the upper wheel 1 to transmit motion. When the upper wheel 1 is turned, the upper wheel 1 drives the lower wheel 2 of the dial wheel 8 to rotate together.

[0039] The upper wheel 1 is movably connected above the lower wheel 2. The upper wheel 1 is used for direct operation. When the upper wheel 1 is turned, the upper wheel 1 drives the lower wheel 2 to rotate together.

[0040] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 7 As shown, the torsion spring feet 301 of the torsion spring 3 are fixed to both sides of the rib 201 of the lower wheel 2 of the dial wheel 8; the center of the torsion spring 3 is aligned with the center of the lower wheel 2.

[0041] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 2 and Figure 5As shown, a Hall PCB7 is fixed on the base plate 5. The Hall PCB7 can sense the change in the magnetic field generated by the magnet 6 and convert it into an electrical signal output. By detecting the change in the magnetic field, the position and rotation of the dial 8 are determined, thereby realizing signal input and control. Three pins 701 are set below the Hall PCB7. The pins 701 are standard pins with a 2.54mm gap. As an output plug, the pins 701 can be directly plugged into the 2.54mm pitch socket of the client. While assisting in fixing the joystick, it can ensure that the plug connection will not fail due to poor soldering or other problems. The Hall PCB7, the base 4, and the base plate 5 are respectively provided with corresponding first connection holes 702, second connection holes 403, and third connection holes 502. The Hall PCB7 is fixedly connected to the base plate 5 and the base 4 by countersunk self-tapping screws 702 passing through the first connection holes 702, second connection holes 403, and third connection holes 502.

[0042] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 6 As shown, the small joystick used on the medical device panel is 25mm long and 10mm wide, taking up little space and making it easy to use on relevant medical devices.

[0043] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 7 and Figure 8 As shown, the cylinder 202 of the lower wheel 2 is aligned with the concave cylinder 401 of the base 4.

[0044] To achieve the above-mentioned technical effects, such as Figure 1 As shown, magnet 6 is fixed in the center hole on the back of lower wheel 2 by interference fit. Magnet 6 can generate a stable magnetic field. When dial 8 rotates, magnet 6 will move with lower wheel 2, thereby changing its relative position with Hall PCB7. Hall PCB7 can convert the change of magnetic field into an electrical signal output. Signal detection can be achieved without physical contact between magnet 6 and Hall PCB7, which reduces wear between components, improves the reliability and service life of the system, and has strong anti-interference ability for magnetic field detection, ensuring the stability of operation.

[0045] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the protruding rib at the bottom of the upper wheel 1 is aligned with the groove of the lower wheel 2 and is fixed with an interference fit. The bottom of the upper wheel 1 is basically parallel to the arc surface of the base 4.

[0046] To achieve the above-mentioned technical effects, such as Figure 9As shown, the four latches 501 of the base plate 5 are fastened into the four latch holes 402 of the base 4, which enables the base plate 5 and the base 4 to be quickly and accurately connected together, facilitating installation and disassembly and improving production efficiency. The latches 501 and the latch holes 402 work together to have a certain self-locking ability, which can prevent relative displacement between the base plate 5 and the base 4 after being fastened.

[0047] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the upper wheel 1, lower wheel 2, base 4 and base plate 5 are made of POM plastic; the torsion spring 3 is made of stainless steel; and the magnet 6 is made of neodymium iron boron.

[0048] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
