[0014] (III) Beneficial effects

[0015] After the control signal is generated by the handle assembly and transmitted to the control circuit board, a control signal is sent to the transverse movement mechanism of the catheter bed. Specifically, the unlocking switch is touched when the pressing cap moves downward with the flexible shaft, and then the flexible shaft touches the corresponding pressure sensors located in the front, back, left and right directions to generate the corresponding lateral movement control signal. That is, before the front, back, left and right control signals are generated, the unlocking switch needs to be touched to keep it in an operable state, thereby achieving risk avoidance and avoiding accidental touches.

At the same time, pressure sensors 5 are installed on the fixed seat 6, which are respectively located on the front side, rear side, left side and right side of the flexible shaft. The pressure sensor 5 and the unlocking switch 11 are both electrically connected to the control circuit board. At the same time, a pressing cap 4 is also provided on the fixed seat 6, and the upper end of the flexible shaft is connected to the pressing cap 4.

[0025] The upper end of the flexible shaft is positioned and connected by pressing the cap 4, and during operation, the flexible shaft is moved downward by pressing the cap 4 to touch the unlocking switch 11. When in the unlocking state, the flexible shaft touches the pressure sensors 5 located at the front, rear, left and right sides respectively, generating corresponding pressure signals and transmitting them to the circuit control board to form control signals, driving the transverse movement mechanism in the catheter bed, and realizing transverse movement adjustment of the bed board in the corresponding direction. The flexible shaft is elastic and can maintain the coaxial position between the position of the pressure sensor 5 and the position of touching the unlocking switch 11 during the downward movement. After the operation is completed, the reset of the flexible shaft is realized by the reset spring 10.

[0026] When performing a touch operation, the unlocking switch 11 must be in the unlocking state to trigger the pressure sensor 5 to generate a corresponding signal, thereby preventing misoperation.
