[0050] See also Figure 2 and Figure 3 As shown, in an embodiment of the present invention, an endoscopic surgery power system is provided, comprising: a device housing 1 , and a battery power compartment 2 and a negative pressure channel 3 arranged inside the device housing 1 .

[0051] An integrated control button 13 is provided on the device housing 1 .

[0052] A motor start / stop speed regulating switch 23 is provided on the battery power compartment.

[0053] A movable battery power compartment 2 is used to provide power to the motor, eliminating the need for a main unit and a foot pedal, reducing the number of pipe connections between different parts of the device, making the endoscopic surgery power system more portable, and reducing restrictions on the doctor's activity space during surgery.

[0054] The integrated control button 13 is configured as follows: when the integrated control button 13 is pressed, the negative pressure channel 3 and the motor start / stop speed regulating switch 23 are opened in sequence, and the negative pressure channel 3 is connected and the motor in the battery power compartment 2 is started accordingly.

[0055] like Figure 3 As shown, the battery power compartment of the endoscopic surgery power system provided in the preferred embodiment of the present invention includes a motor, a removable power battery and a first motor connector 21, and the first motor connector 21 matches the second motor connector on the device housing.

[0056] like Figure 4 As shown, a screw cover 5 is provided at the rear end of the device housing 1 where the battery power compartment 2 is installed, for sealing the device housing 1 after the battery power compartment 2 is installed.

[0057] like Figure 5 As shown, at the front end of the device housing 1 is a quick connector 11 for connecting the endoscopic surgery power system with the tool.

[0058] like Figure 3 As shown, a battery charging interface 22 is also provided on the battery power compartment 2 for charging the battery.

[0059] like Figure 6 As shown, a hook 25 is provided at the rear end of the battery power compartment for taking the battery power compartment out of the device housing.

[0060] like Figure 7 As shown, the negative pressure channel 3 passes through the integrated control button 13 to the negative pressure outlet 4. The integrated control button 13 includes a push rod block 131 for pressing and a retractable first push rod 132. The position of the push rod block outside the hand pressing is set to an arc shape that fits the hand. The push rod block 131 is opposite to the hand pressing position. A third groove body 135 matching the first push rod 132 is provided, and the first push rod 132 and the push rod block 131 are connected together through the third groove body 135.

[0061] In a preferred embodiment of the present invention, the first push rod 132 and the push rod stop block 131 are integrally fixedly connected. The integrally fixed connection can prevent the position offset between the first push rod 132 and the push rod stop block 131, thereby avoiding the integrated control button 13 from being pressed smoothly.

[0062] A spring is provided in the gap between the first push rod 132 and the push rod stop block 131. When the pressure applied to the push rod stop block 131 disappears, the spring pushes the push rod stop block 131 to restore, so as to shut down the endoscopic surgery power system.

[0063] The movement of the push rod block 131 is divided into two stages. In the first stage, pressure is applied to the push rod block 131 to push the push rod block 131 to move. The push rod block 131 pushes the first push rod 132 to connect the through hole 134 with the negative pressure channel 3 to achieve control of the negative pressure.

[0064] like Figure 7 As shown, in a preferred embodiment of the present invention, the integrated control button 13 further includes a fixing block 136 , on which a first slot body 137 matching the first push rod 132 and a second slot body 138 matching the negative pressure channel 3 are provided.

[0065] One end of the first groove 137 away from the first push rod 132 is not penetrated, so as to prevent the first push rod 132 from moving, resulting in a reduction in the communicating area between the through hole 134 and the negative pressure channel 3 .

[0066] The second groove body 138 is connected vertically to communicate with the negative pressure channel 3 .

[0067] The first groove body 137 and the second groove body 138 are cross-connected to each other so that the negative pressure channel 3 can pass through the connecting portion.

[0068] One end hole of the second slot body 138 is connected to one end of the negative pressure channel 3 extending in the direction of the blade head, and the other end hole of the second slot body 138 is connected to one end of the negative pressure channel 3 extending in the direction of the negative pressure outlet 4. The first push rod 132 is inserted into the first slot body 137. When no pressure is applied to the push rod stop block 131, the through hole 134 on the first push rod 132 is staggered with the hole inside the second slot body 138. After pressure is applied to the push rod stop block 131, the through hole 134 overlaps with the hole inside the second slot body 138, so that the negative pressure channel 3 is connected, providing a negative pressure environment for surgery.

[0069] The first push rod 132 and the negative pressure channel 3 are fixed by the fixing block 136 , so as to ensure the airtightness of the negative pressure channel 3 and improve the stability of the negative pressure environment.

[0070] like Fig. 9 As shown, in a preferred embodiment of the present application, the integrated control button includes a Y-shaped push rod 133 , and the two end ends of the forked Y-shaped push rod 133 are located on both sides of the negative pressure channel 3 , corresponding to the position of the push rod stop block 131 .

[0071] In the second stage, the pressure applied to the push rod stopper 131 is further increased, so that the push rod stopper 131 moves further toward the direction of the Y-shaped push rod 133, thereby pushing the Y-shaped push rod 133 to move.

[0072] like Figure 7 and 9 As shown, a spring is provided at the handle end of the Y-shaped push rod 133, and the position of the handle end corresponds to the position of the motor start / stop speed regulating switch 23. During the movement of the Y-shaped push rod 133, the through hole is kept connected to the negative pressure channel, and the Y-shaped push rod 133 contacts the motor start / stop speed regulating switch 23 to start the motor.

[0073] like Figure 7 and 8 As shown, a through hole 134 is provided at one end of the first push rod 132 away from the push rod stop block 131 , and the size and shape of the through hole 134 match the negative pressure channel 3 .

[0074] In a preferred embodiment of the present invention, the shape of the through hole includes a rectangle and two semicircles with one set of opposite sides of the rectangle as the diameter, similar to the straight-edged ellipse of a runway. The cross-sectional shape of the negative pressure channel is a circle, and the diameter of the circle is equal to the diameter of the semicircle.

[0075] In the process of pushing the first push rod 132 to move, one of the semicircular shapes of the through hole 134 overlaps with the negative pressure channel 3, and the through hole 134 should have the largest area connected to the negative pressure channel 3 to ensure that a stable and unobstructed negative pressure environment is provided for the operation of the endoscopic surgery power system. Further press the push rod block 131, the push rod block 131 pushes the Y-shaped push rod 133 to touch the motor start-stop speed control switch 13, and the first push rod 132 continues to move. At this time, the straight-edged elliptical through hole 134 will also move together. Due to the existence of the middle rectangle, the through hole 134 will always remain connected to the negative pressure channel 3, and the connected area is the largest. From the beginning of the through hole 134 and the negative pressure channel 3 are connected, during the entire process of the first push rod 132 pushing, the negative pressure channel 3 is in a state of having the largest area connected to the through hole 134 to ensure that a stable and unobstructed negative pressure environment is provided for the entire surgical process.

[0076] The Y-shaped push rod 133 is set so that the push rod block 131 can control the start and stop of the motor and the speed during the second stage of movement. The speed control is specifically implemented as follows: the motor start and stop speed regulating switch 23 includes a plurality of different power control gears, and each power control gear corresponds to the distance that the Y-shaped push rod 133 pushes the motor start and stop speed regulating switch to move.

[0077] When the Y-shaped push rod 133 contacts the motor start / stop speed regulating switch 23, the first distance is 0, and the motor is started and the motor is at the first power, so that the motor outputs at the first power. When the Y-shaped push rod 133 continues to push the motor start / stop speed regulating switch 23 to move to the second distance, the second power control gear of the motor start / stop speed regulating switch 23 is reached, so that the motor outputs at the second power. By analogy, multiple different power control gears can be set according to needs.

[0078] Correspondingly, a control circuit matching one-to-one with the power control gear position is provided on the internal control circuit board of the battery power compartment 2 to realize the conversion and control of the motor power.

[0079] The cooperation between the first push rod 132 and the Y-shaped push rod 133 realizes the control of negative pressure, motor start and stop and speed during the movement of the push rod block 131, and concentrates the negative pressure control, motor start and stop control and motor speed control on the same button, thereby improving the convenience and flexibility of the doctor's operation during the operation.

[0080] The device housing 1 is also provided with a device power switch pull 12 , and the battery power compartment 2 is also provided with a battery power compartment power switch 24 .

[0081] The device power switch 12 is configured to: when the device power switch 12 is turned, the battery power compartment power switch 24 is turned on to power on the battery power compartment 2.

[0082] like Figure 5 and 10 As shown, the device power switch pull 12 is embedded in the side of the device housing 1, including a lever 121 and a second push rod 122. The position of the second push rod 122 corresponds to the position of the battery power compartment power switch 24. When the lever 121 of the device power switch pull 12 is toggled, the lever 121 pushes the second push rod 122 to move, so that the second push rod 122 presses the battery power compartment power switch 24 to power on the battery power compartment 2. After the lever 121 is toggled, let go, and the lever 121 will reset itself.

[0083] The equipment power switch pull 12 is simple and easy to use, highly reliable and durable. The equipment power switch pull 12 is used to control the battery power compartment power switch 24, which is convenient to operate, safe and reliable.

[0084] In a preferred embodiment of the present invention, the battery power compartment power switch 24 is a self-locking switch. When pressed for the first time, the battery power compartment power switch 24 is turned on and maintained. When the work is completed and the endoscopic surgical power system needs to be turned off, the lever 121 is pushed again, the battery power compartment power switch 24 is turned off, and the battery power compartment power switch 24 is restored at the same time.

[0085] The self-locking switch has a reasonable design and a solid structure. It can maintain stable performance under various environmental conditions. Its contact material has excellent wear resistance and corrosion resistance, ensuring the long-term reliability of the switch. The self-locking switch is easy to operate and can switch the switch state with just a light press. Its unique locking mechanism avoids misoperation caused by external force.

[0086] An endoscopic surgical power system provided in this embodiment is aimed at the technical problems of the existing endoscopic surgical power system with numerous pipelines, poor portability, complicated operation and high cost. The endoscopic surgical power system of the present invention includes: an equipment housing, and a battery power compartment and a negative pressure channel arranged inside the equipment housing; an equipment power switch pull and an integrated control button are arranged on the equipment housing; a motor start-stop speed regulating switch and a battery power compartment power switch are arranged on the battery power compartment; the equipment power switch pull is configured to: when the equipment power switch pull is toggled, the battery power compartment power switch is turned on to power on the battery power compartment; the integrated control button is configured to: when the integrated control button is pressed, the negative pressure channel and the motor start-stop speed regulating switch are opened in sequence, and the negative pressure channel is connected and the motor in the battery power compartment is operated accordingly. The endoscopic surgical power system of the present invention realizes the integrated control of negative pressure and power, has low design and production costs, high operational flexibility and convenience, and the equipment is portable, compact, and highly portable, reducing the restrictions on the doctor's activity space during surgery.

[0087] The above-mentioned embodiments only express several preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
