Description

Surgical system with operating table movement speed change function

The present invention relates to a surgical system, in particular to a surgical system with a speed-changing function for the movement of an operating table.

The power sources in surgical systems include manual drive, hydraulic drive and motor drive. Hydraulic drive surgical systems are the mainstream power sources for surgical systems on the market because of their stability, no shaking and high load capacity. However, the requirements for modern surgical precision are gradually increasing, and surgical systems powered by hydraulic drive cannot achieve fine movements. Therefore, how to improve the speed of the operating table is an urgent problem to be solved.

The present invention provides a surgical system with a speed-changing function for the operating table to solve the above-mentioned problem.

The present invention discloses a surgical system, comprising an oil tank; a hydraulic pump coupled to the oil tank for outputting a liquid volume from the oil tank; a motor coupled to the hydraulic pump for driving the hydraulic pump to output the liquid volume from the oil tank, wherein the liquid volume output from the oil tank by the hydraulic pump is determined according to a motor speed of the motor; an electromagnetic valve coupled to the oil tank and the hydraulic pump for performing a liquid volume distribution according to the liquid volume; at least one hydraulic cylinder coupled to the electromagnetic valve for performing a bed motion of the surgical system according to the liquid volume distribution; and a controller coupled to the motor for adjusting the motor speed; wherein a bed motion speed of the bed motion is determined according to the motor speed.

Figure 2 is a schematic diagram of a process of a surgical system according to an embodiment of the present invention.

FIG. 1 is a schematic diagram of a surgical system 10 according to an embodiment of the present invention. The surgical system 10 includes an oil tank 100, a hydraulic pump 102, a motor 104, an electromagnetic valve 106, at least one hydraulic cylinder 108, and a controller 110. The oil tank 100 contains a liquid (such as hydraulic oil, but not limited to this) used to drive at least one hydraulic cylinder 108 to perform bed movements. The hydraulic pump 102 is coupled to the oil tank 100 to output a liquid amount of the liquid in the oil tank 100. The motor 104 is coupled to the hydraulic pump 102 to drive the hydraulic pump 102 to output the liquid amount in the oil tank 100. According to a motor speed of the motor 104, the amount of liquid output from the oil tank 100 by the hydraulic pump 102 is determined. The electromagnetic valve 106 is coupled to the oil tank 100 and the hydraulic pump 102, and is used to perform a liquid amount distribution according to the liquid amount. At least one hydraulic cylinder 108 is coupled to the electromagnetic valve 106, and is used to perform a bed movement of the surgical system 10 according to the liquid amount distribution. The controller 110 can be a tablet computer or a remote controller, but is not limited thereto. The controller 110 is coupled to the motor 104, and is used to adjust 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 amount in the oil tank corresponding to the motor speed. After the hydraulic pump 102 outputs the liquid amount, the electromagnetic valve 106 distributes the liquid amount to at least one hydraulic cylinder 108, so that at least one hydraulic cylinder performs the bed movement of the surgical system 10 according to the result of the liquid amount distribution. Since the bed movement speed of the bed movement performed by at least one hydraulic cylinder 108 is determined according to the liquid amount, and the liquid amount is determined according to the motor speed. In this case, according to the motor speed, a bed movement speed of the bed movement is determined.

In one embodiment, when the motor speed is changed from a low speed to a high speed, the bed movement speed is increased. That is, when the motor speed is increased, the motor 104 can drive the hydraulic pump 102 to output a larger amount of liquid in the oil tank 100. In this case, the bed movement speed of at least one hydraulic cylinder 108 performing the bed movement will also be increased, so that the bed can quickly reach the position required by the clinician to facilitate emergency rescue. In one embodiment, when the motor speed is changed from a high speed to a low speed, the bed movement speed is reduced. That is, when the motor speed is reduced, the motor 104 can drive the hydraulic pump 102 to output a smaller amount of liquid in the oil tank 100. In this case, the bed movement speed of at least one hydraulic cylinder 108 will also be reduced. By reducing the bed movement speed, the clinician can quickly achieve the fine adjustment of the bed movement required by the clinician, improving the situation that the original hydraulically driven surgical system cannot achieve fine movements.

In one embodiment, the controller 110 further includes an action button and a somatosensory device. The action button instructs the controller 110 to adjust the motor speed. The somatosensory device (such as a gravity sensor (G sensor) or a gyroscope, but not limited thereto) detects a back-and-forth swing speed of the controller. In one embodiment, when the controller 110 receives an instruction from the action button and the somatosensory device successfully detects the back-and-forth swing speed, the controller adjusts the motor speed according to the back-and-forth swing speed. For example, when the bed movement speed needs to be adjusted according to the surgical requirements, the clinician can press the action button, so that the controller receives the instruction 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 somatosensory device in the controller 110 successfully detects the speed of the controller swinging back and forth, the controller 110 adjusts the motor speed according to the swinging speed. For example, when the bed needs to move quickly to the position required by the clinician, the clinician can speed up the swinging speed of the controller 110, so that the somatosensory device detects that the swinging speed of the controller 110 increases, and then the controller 110 knows that the motor speed needs to be increased to increase the bed movement speed. When the clinician needs to finely adjust the position of the bed, the clinician can reduce the forward and backward swing speed of the swing controller 110, so that the somatosensory device detects that the forward and backward swing speed of the controller 110 is reduced, and the controller 110 is informed that the motor speed needs to be reduced to reduce the bed movement speed.

The operation of the aforementioned surgical system can be summarized as a process 20 in Figure 2. Process 20 includes the following steps: Step 200: Start.

Step 202: The controller receives an instruction from an action button.

Step 204: The controller's somatosensory device detects the controller's forward and backward swing speed.

Step 206: The controller adjusts the motor speed of the motor according to the forward and backward swing speed.

Step 208: According to the motor speed, the motor drives the hydraulic pump to output the amount of liquid in the oil tank.

Step 210: According to the liquid volume, the solenoid valve performs liquid volume distribution.

Step 212: Based on the liquid volume distribution, at least one hydraulic cylinder performs a bed movement of the surgical system.

Step 214: End.

In summary, the present invention provides a surgical system with a speed-changing function for the operation table. By adjusting the motor speed to control the amount of liquid output by the hydraulic pump, the operation speed of the operation table of the surgical system can be adjusted. By changing the motor speed, the operation table can be quickly moved to the desired position or the operation of the operation table can be finely adjusted. Therefore, the problems in this field can be solved.

The above is only the preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
