[0002] The power source in the surgical system includes manual driving, oil pressure driving and motor driving. The oil pressure driven surgical system is the mainstream of the current market because it has the characteristics of stability, no shaking and high bearing weight. However, the requirement of modern surgical precision is increasing, and the oil pressure driven surgical system cannot achieve fine action. Therefore, how to improve the bed action variable speed is a problem to be solved. SUMMARY

[0008] Figure 1FIG. 1 is a schematic diagram of a surgical system 10 according to an embodiment of the present application. The surgical system 10 includes a tank 100, a hydraulic pump 102, a motor 104, a solenoid valve 106, at least one hydraulic cylinder 108, and a controller 110. The tank 100 contains a liquid (e.g., hydraulic oil, but not limited to) for driving the at least one hydraulic cylinder 108 to perform a bed action. The hydraulic pump 102 is coupled to the tank 100 for outputting a liquid volume of the tank 100. The motor 104 is coupled to the hydraulic pump 102 for driving the hydraulic pump 102 to output the liquid volume of the tank 100. The liquid volume outputted by the hydraulic pump 102 is determined according to a motor speed of the motor 104. The solenoid valve 106 is coupled to the tank 100 and the hydraulic pump 102 for performing a liquid volume distribution according to the liquid volume. The at least one hydraulic cylinder 108 is coupled to the solenoid valve 106 for performing a bed action of the surgical system 10 according to the liquid volume distribution. The controller 110 can be a tablet computer or a remote controller, but not limited to. The controller 110 is coupled to the motor 104 for adjusting the motor speed. That is, according to an instruction of the controller 110, the motor speed of the motor 104 is determined, and according to the motor speed, the motor 104 drives the hydraulic pump 102 to output a liquid volume of the tank corresponding to the motor speed. After the hydraulic pump 102 outputs the liquid volume, the solenoid valve 106 distributes the liquid volume to the at least one hydraulic cylinder 108, so that the at least one hydraulic cylinder performs the bed action of the surgical system 10 according to the result of the liquid volume distribution. Since the bed action speed of the bed action performed by the at least one hydraulic cylinder 108 is determined according to the liquid volume, and the liquid volume is determined according to the motor speed. In this case, according to the motor speed, a bed action speed of the bed action is determined.

[0009] In an embodiment, when the motor speed is switched from a low speed to a high speed, the bed action speed is increased. That is, when the motor speed is increased, the motor 104 can drive the hydraulic pump 102 to output a larger liquid volume of the tank 100, and in this case, the bed action speed of the bed action performed by the at least one hydraulic cylinder 108 is also increased, so that the bed can quickly reach a position required by a clinician, which is beneficial for emergency rescue. In an embodiment, when the motor speed is switched from a high speed to a low speed, the bed action speed is decreased. That is, when the motor speed is decreased, the motor 104 can drive the hydraulic pump 102 to output a smaller liquid volume of the tank 100, and in this case, the bed action speed of the bed action performed by the at least one hydraulic cylinder 108 is also decreased. By decreasing the bed action speed, fine adjustment of the bed action required by the clinician can be quickly reached, which improves the situation that the original hydraulic-driven surgical system cannot perform fine adjustment.

[0010] In one embodiment, the controller 110 further comprises an action button and a motion sensing device. The action button instructs the controller 110 to adjust the motor speed. The motion sensing device (e.g. a Gsensor or a gyroscope, but not limited to) detects a back-and-forth swinging speed of the controller. In one embodiment, when the controller 110 receives an indication of the action button and the motion sensing device successfully detects the back-and-forth swinging speed, the controller adjusts the motor speed according to the back-and-forth swinging speed. For example, when the bed action speed needs to be adjusted according to the surgical requirement, the clinician can press the action button so that the controller receives the indication of the action button to know that the motor speed needs to be adjusted, then the clinician holds the controller 110 and swings it back and forth, when the motion sensing device in the controller 110 successfully detects the back-and-forth swinging speed of the controller, the controller 110 adjusts the motor speed according to the back-and-forth swinging speed. For example, when the bed action needs to reach the position required by the clinician quickly, the clinician can increase the back-and-forth swinging speed of the controller 110, so that the motion sensing device detects an increase in the back-and-forth swinging speed of the controller 110, and thus the controller 110 knows that the motor speed needs to be increased to increase the bed action speed. When the clinician needs to finely adjust the position of the bed, the clinician can reduce the back-and-forth swinging speed of the controller 110, so that the motion sensing device detects a decrease in the back-and-forth swinging speed of the controller 110, and thus the controller 110 knows that the motor speed needs to be reduced to reduce the bed action speed.

[0011] The operation of the aforementioned surgical system can be summarized as a flow 20 in Figure 2 The flow 20 comprises the following steps:

[0012] Step 200: Start.

[0013] Step 202: The controller receives an indication of the action button.

[0014] Step 204: The motion sensing device of the controller detects a back-and-forth swinging speed of the controller.

[0015] Step 206: The controller adjusts the motor speed of the motor according to the back-and-forth swinging speed.

[0016] Step 208: The motor drives the hydraulic pump to output a liquid amount of the oil tank according to the motor speed.

[0017] Step 210: The solenoid valve performs liquid amount distribution according to the liquid amount.

[0018] Step 212: At least one hydraulic cylinder performs a bed action of the surgical system according to the liquid amount distribution.

[0019] Step 214: End.

[0020] In summary, the present application provides a surgical system with a function of changing the speed of a table movement. The speed of the table movement of the surgical system can be adjusted by adjusting the rotation speed of a motor to control the amount of liquid output by an oil hydraulic pump. The rotation speed of the motor can be changed to quickly reach a required position of the table or finely adjust the movement of the table. Thus, the problems in the art can be solved.
