Detailed implementation manner

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a stripping device for thyroid tumor surgery, including a grip 1, a sleeve 2 is fixedly installed at the top end of the grip 1, a driving motor 3 is fixedly connected to the inner bottom wall of the sleeve 2, one end of a lead screw 4 is fixedly connected to the output end of the driving motor 3, the other end of the lead screw 4 is rotationally connected to a bearing in a bearing hole opened on the inner top wall of the sleeve 2, a slider 5 is threadedly connected to the lead screw 4, an auxiliary guide rail 6 is fixedly connected to the right inner wall of the sleeve 2, and the slider 5 is also slidably connected to the auxiliary guide rail 6 through a connecting rod. A rectangular through hole 7 is opened on the top wall of the sleeve 2 and to the left of the lead screw 4. An extension rod 8 is slidably connected in the rectangular through hole 7. One end of the extension rod 8 located in the sleeve 2 is fixedly connected to the slider 5, and a visual stripping component 9 is arranged on the extension rod 8.

[0020] The auxiliary guide rail 6 provides stability for the movement of the slider 5. The driving motor 3 is a servo driving motor, which provides precision for the extension and retraction of the extension rod 8. When the driving motor 3 drives the lead screw 4 to rotate forward, the slider 5 on the lead screw 4 drives the extension rod 8 to extend outward. When the driving motor 3 drives the lead screw 4 to rotate reversely, the slider 5 on the lead screw 4 drives the extension rod 8 to retract inward. It should be noted that the moving positions of the slider 5 are all memory-enabled. For example, when the extension rod 8 on the slider 5 extends outward a certain distance, this distance is the distance required for work and after staying at this position for a long time, the slider 5 will remember this position. When the slider 5 retracts and then extends outward again, it will move to the previously memorized position. This technical solution actually provides a combination of a servo motor + a lead screw slide rail, which is widely used in processing scenarios with high-efficiency and high-precision motion control requirements. It realizes high-efficiency and precise motion control through servo motor drive, the cooperation of positive and negative thread lead screws and slide rail sliders, and is supplemented by proximity switches for position limitation. Servo motor: As the driving source, the servo motor realizes precise position, speed, and force control through the controller, ensuring the repeated precision and stability of the motion. Positive and negative thread lead screw: The lead screw adopts a positive and negative thread design, which can realize the two-way sliding function. This design is commonly used in tooling fixtures in scenarios that require two-way adjustment or position locking, such as mold opening and closing, workpiece clamping, etc. Based on the high-precision encoder built into the servo motor, the rotor position can be real-time feedback. The servo motor system provides closed-loop feedback through the integrated encoder. The driver's built-in storage unit records position data, relies on the absolute value encoder to maintain the position reference, and provides the position memory function, which belongs to the well-known technology in this technical field and is the basic function of the lead screw guide rail system. In addition, in this technical field, the memory of the slider position can also be detected and memorized through an external grating scale or magnetic grating scale as a position sensor, which is a conventional technical choice for those skilled in this technical field.

[0021] The visual peeling component 9 includes a mounting bracket 91, which is fixedly connected to the extension rod 8. A visual sensor 92 is fixedly connected to the mounting bracket 91. The number of visual sensors 92 is two in total, which are respectively equidistantly installed on the front and back sides of the mounting bracket 91. A lighting lamp 917 is also fixedly connected to the mounting bracket 91. On the side of the mounting bracket 91 away from the lighting lamp 917, a signal transmitter 93 is fixedly connected. The signal transmitter 93 is electrically connected to the visual sensor 92. An independent power supply 94 is fixedly connected to the mounting bracket 91 on the side of the signal transmitter 93.

[0022] The visual sensor 92 is an existing technical solution, which converts the image into a digital signal and wirelessly transmits it to the screen in the operating room, facilitating the doctor's observation of the surgical site. The lighting lamp 917 acts to illuminate the surgical site and provide a better observation environment.

[0023] The top end of the extension rod 8 is fixedly connected with a long rod 95. On the left and right sides of the long rod 95 and on the side far from the extension rod 8, there are fixedly connected with slide rails 96. On both of the two slide rails 96, there is a sliding block 97 slidably connected. On the sliding block 97, there is a screw rod 98 fixedly connected. On the screw rod 98, there is a stripping clip 99 threadedly connected.

[0024] On the left and right sides of the grip 1, there are respectively provided with placing grooves 910. Inside the two placing grooves 910, there are fixedly connected with spring rods 911. The output ends of the two spring rods 911 are fixedly connected with arc-shaped grips 912. On the lower surfaces of the two arc-shaped grips 912, there is fixedly connected with one end of a straight rod 913. The other end of the straight rod 913 penetrates through the slide rail 96 on the long rod 95 and is fixedly connected with the corresponding sliding block 97. On both the long rod 95 and the slide rail 96, there are provided with moving through holes 914. The straight rod 913 is located inside the moving through hole 914.

[0025] It should be noted that the arc-shaped grip 912 can move through the spring rod 911. When the arc-shaped grip 912 moves inwards, it will drive the sliding block 97 to move through the straight rod 913, and clamp the tumor to be stripped through the stripping clip 99.

[0026] On the front side of the grip 1, there is also fixedly connected with a power switch 915.

[0027] The power switch 915 is used to control the switches of the visual sensor 92, the lighting lamp 917 and the drive motor 3. It should be noted that the control button for controlling the drive motor 3 is located on the side of the power switch 915. The right side is the forward rotation and reset button of the drive motor 3, and the left side is the reverse rotation button of the drive motor 3.

[0028] At the bottom end of the grip 1, there is fixedly installed a charging port 916. The charging port 916 is electrically connected with the independent power supply 94.

[0029] Principle of use: When using the peeling device for thyroid tumor surgery, the user starts the drive motor 3 through the forward rotation control button on the power switch 915 and makes the output end rotate forward. When the drive motor 3 rotates forward, it drives the lead screw 4 to rotate. When the lead screw 4 rotates, the extension rod 8 on the slider 5 extends outwards. After the extension rod 8 moves to the required position, release the forward rotation control button, and the extension rod 8 is positioned. The user turns on the visual sensor 92 and the lighting lamp 917 switch to check whether the components can be used. When performing peeling, the user squeezes and moves the two arc-shaped grips 912 inward through the spring rod 911. When the two arc-shaped grips 912 move relatively, the moving block 97 is driven by the straight rod 913 on the arc-shaped grip 912 to move on the slide rail 96, and the peeling clip 99 contacts and clamps the position to be peeled. At this time, the user touches the reverse button, and the drive motor 3 rotates in reverse. The slider 5 drives the extension rod 8 to retract inward on the lead screw 4, cooperating with the user's peeling operation to complete the peeling of the tumor. After peeling, place the tumor in an external storage container and release the reverse button, and then touch the reset button. The slider 5 drives the extension rod 8 to reset. It should be noted that the buttons on the power switch 915 are all contact buttons, which are energized when contacted and de-energized when released.
