[0002] In endoscopic surgery, negative pressure suction device is the key equipment to maintain clear surgical field and ensure safe operation.

A detachable main unit casing 121 is installed at the top of the main unit base 101.

[0027] It should be further noted that the control panel 109 has a human-computer interaction interface.

[0028] Furthermore, a solenoid valve 103 is installed at the tail end of the negative pressure pipeline 102, and a negative pressure port 113 is connected to the bottom of the solenoid valve 103.

[0029] Furthermore, a pressure detector 116 is installed between the negative pressure pump 118 and the pressure stabilizing pump 114, and the pressure detector 116 is connected to the negative pressure pipeline 102.

[0030] It should be further noted that a silencer is installed on one side of the negative pressure pump 118.

[0031] Furthermore, a main control unit 119 is installed inside the main unit base 101, and the main control unit 119 is connected to the control panel 109 for data transmission.

[0032] Furthermore, an indicator light 111 is provided on one side of the front end of the main unit base 101. The indicator light 111 serves to indicate the operation of the device, and a handle interface 112 is provided below the indicator light 111.

[0033] Further, the host base 101 is provided with a driving motor 120 on one side, the driving motor 120 is in power connection with the handle interface 112, and the handle interface 112 is provided with a detachable planing surgical cutter 110 on one end.

[0034] It should be further explained that the planing surgical cutter 110 is replaced according to different surgical requirements.

[0035] It should be further explained that when the driving motor 120 is started, the installed planing surgical cutter 110 can be driven to rotate through the power-connected handle interface 112, thereby meeting the planing surgical requirement.

[0036] Further, the host base 101 is provided with a foot brake interface 106 on one side of the front end, and the foot brake interface 106 is provided with an electronic foot pedal 107 on one side, the electronic foot pedal 107 is in data connection with the foot brake interface 106 through the cable 108, and the electronic foot pedal 107 is used for controlling the support base 105 and is in signal connection with the main control unit 119.

[0037] The use method of the scheme is as follows:

[0038] S1, place the host on a stable and flat operation table, connect the power supply, and start the device. The control screen 109 displays a man-machine interface, the system performs self-checking, and the indicator light 111 displays a standby state.

[0039] S2, according to the type of surgery, select the appropriate planing surgical cutter 110, and install it on the handle interface 112 to ensure firm connection;

[0040] Connect the sterile negative pressure pipeline 102 and the negative pressure pipe 113 to the sterile area of the surgery as required;

[0041] The operator sets the required negative pressure target value, the stable pressure pump working mode and other parameters of this surgery through the control screen 109.

[0042] S3, when the negative pressure pump 118 is started, the electromagnetic valve 103 is in a closed state, the negative pressure pump 118 quickly discharges the air in the negative pressure pipeline 102 and the connected channel, thereby forming a negative pressure suction passage;

[0043] The pressure detector 116 detects the system negative pressure value in real time, converts it into an electric signal, and transmits it to the main control unit 119; the main control unit 119 compares the detection value with the negative pressure value set by the user through the control screen 109;

[0044] If the actual negative pressure is lower than the set value, the negative pressure pump 118 continues to work;

[0045] If the actual negative pressure is higher than the set value, the electromagnetic valve 103 is temporarily opened, so that the negative pressure pipeline 102 is connected with the atmosphere, and positive pressure is introduced to reduce the system negative pressure;

[0046] Through the above closed-loop control process, the actual negative pressure of the system is dynamically stabilized within the set value range.

[0047] S4. During this process, the pressure stabilizing pump 114 continues to work to buffer and compensate for system pressure fluctuations and prevent sudden pressure changes.

[0048] The silencer connected to one side of the negative pressure pump 118 effectively reduces the noise generated by the negative pressure pump 118 during operation.

[0049] S5. During the surgery, the doctor controls the device via the electronic foot pedal 107;

[0050] When the foot pedal is lightly pressed, the foot pedal triggers the first signal, and the main control unit 119 controls the solenoid valve 103 to open, opening the suction channel. At this time, only the suction function is performed to quickly suck out the liquid, blood and other substances in the surgical area to achieve visual clearance.

[0051] When the foot pedal is pressed down, the foot pedal further triggers a second signal. While maintaining the opening of the solenoid valve 103, the main control unit 119 starts the drive motor 120, which in turn drives the shaving surgical blade 110 to rotate at high speed through the handle interface 112 to perform tissue shaving and removal. At this time, under the suction of stable negative pressure, the removed tissue fragments are sucked out in real time.

[0052] S6. After the surgery, release the electronic foot pedal 107, and all power and suction functions will stop;

[0053] The system power is turned off via the control panel 109, external connections are disconnected, and contact components such as the shaving surgical blade 110 and the negative pressure pipe 102 are disassembled, cleaned, and disinfected according to the standard procedures.
