[0031] like Figure 1 As shown, the torque sensor 700 is disposed on the motor 500 and can measure the torque of the motor 500. In practice, the torque sensor 700 can also be installed on the reducer as long as it can measure the torque.

[0032] The motor 500, the linear displacement sensor 300, the angular displacement sensor 600 and the torque sensor 700 are all electrically connected to the control system, and the display screen 800 is electrically connected to the control system. The control system receives signals from the linear displacement sensor 300, the angular displacement sensor 600 and the torque sensor 700, displays the linear displacement value, the angular displacement value and the torque value on the display screen 800, and draws a linear displacement-time curve, an angular displacement-time curve and a torque-time curve.

[0033] In addition, the control system can also be set to draw torque-linear displacement curves and torque-angular displacement curves according to the measured data to meet the use requirements under different working conditions.

[0034] During implementation, the linear displacement sensor 300 may be the MSC500 model of the SIKO brand, the angular displacement sensor 600 may be the P2021 model of Shenzhen Mirante Technology Co., Ltd., and the torque sensor 700 may be the HCNJ-101 model of Beijing Haibohua Technology Co., Ltd.

[0035] When in use, the operator clamps the catheter to be connected and the non-flared joint onto the fixture 110, and clamps the expander onto the connecting joint so that the core shaft of the expander and the catheter remain coaxial. Start the motor 500, the core shaft rotates under the action of the motor 500, and then manually move the mounting plate 200 so that the motor 500 and the core shaft as a whole approach the fixture 110, the core shaft squeezes the needle roller on the retaining tube, the needle roller squeezes the inner wall of the catheter, and squeezes the tube wall material into the groove of the non-flared joint, thereby gradually realizing internal rolling. In this process, the linear displacement sensor 300, the angular displacement sensor 600 and the torque sensor 700 can measure the corresponding data respectively, and transmit the data to the control system. The control system draws the curve on the display screen 800 according to the data, and the operator can observe the progress of the internal rolling process according to the curve on the display screen 800.

[0036] Compared with the existing technology, the multifunctional catheter internal rolling equipment can detect the linear displacement, angular displacement and torque value of the core shaft, and simultaneously draw the time-linear displacement curve, the time-angular displacement curve and the time-torque curve, so that the operator can use the three data and three curves to observe the progress of the internal rolling, and they can verify each other, which is convenient for the operator to determine the result of the internal rolling, avoid the situation that cannot be judged by only one method, and improve the practicality of the equipment.

[0037] In some embodiments, the linear displacement sensor 300 is a magnetic displacement sensor, and the sensing plate 400 is a magnetic strip. The magnetic displacement sensor is used to detect the distance, which is accurate, simple to install and debug, and easy to operate. In addition, the linear displacement can also be detected in the form of a photoelectric sensor and a reflector, a laser rangefinder, a grating ruler, a resistive displacement sensor, a wire displacement sensor, and a linear displacement sensor, which are not limited here.

[0040] In some embodiments, the motor 500 is a servo motor, which is provided with an encoder. The servo motor's own encoder can also be used to detect angular displacement, so that when a servo motor is selected, the angular displacement sensor 600 does not need to be installed. At this time, the data recorded by the encoder needs to be transmitted to the control system, and the control system can draw a time-angular displacement curve based on the data of the encoder. In implementation, the servo motor 500 can be selected from the INOVANCE brand model: MS1H2-40C30CD, Type: A331R.

[0041] In some embodiments, Figure 3 As shown, the fixture 110 is provided with an optical axis 130, which extends along the length direction of the guide rail 120. A bracket 140 is slidably connected to the optical axis 130, and the bracket 140 is supported under the connecting joint, so that when the internal rolling is performed, the connecting joint and the core shaft can be supported by the bracket 140, thereby ensuring the coaxiality of the connecting joint and the conduit and ensuring the quality of the internal rolling.

[0042] In some embodiments, Figure 4As shown, a handle 210 is provided on the mounting plate 200. The operator can pull the entire mounting plate 200 through the handle 210, thereby driving the motor 500, the mandrel, etc. to approach the fixture 110, making the mandrel close to the catheter, realizing the feeding of the mandrel, and finally completing the inner rolling operation.

[0043] In some embodiments, Figure 4 As shown, the mounting plate 200 is provided with a threaded rod 220 and a threaded hole, the threaded rod 220 is threadedly connected to the threaded hole of the mounting plate 200, the top of the threaded rod 220 is provided with a handle 230, and the bottom of the threaded rod 220 is provided with a bottom plate 240. When the threaded rod 220 rotates, the bottom plate 240 can abut against or separate from the operating table 100. After use, the handle 230 can be turned to make the bottom plate 240 abut against the operating table 100, thereby preventing the mounting plate 200 from moving again. Before the next use, the handle 230 can be turned to separate the bottom plate 240 from the operating table 100.

[0044] In some embodiments, the operating table 100 is provided with an installation cavity, and the relevant electronic components of the control system are installed in the installation cavity, which can play a protective role and reduce the possibility of damage. The front side of the installation cavity is formed with an opening and a door panel is provided, so that the installation cavity can be opened and closed.

[0045] In some embodiments, Figure 2 As shown, the display screen 800 is installed on the operating table 100 through a vertical tube 810. The interior of the vertical tube 810 is connected to the installation cavity of the operating table 100. A cable is arranged in the vertical tube 810. The cable connects the control system and the display screen 800 to realize signal transmission.

[0046] In some embodiments, Figure 3 As shown, a support leg 150 is provided below the operating table 100 . The number of the support legs 150 is generally four, and the support legs 150 can play a role in supporting the entire operating table 100 .
