Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a medical debridement water power system. Background Art

[0002] Traditional debridement methods all have limitations. For example, surgical debridement requires a high level of physician experience, can cause extensive tissue loss, and can be intolerable to elderly, frail, or critically ill patients, leading to increased complications. Autolytic debridement takes a long time to complete, and the moisture produced during the autolytic process easily soaks into the skin, requiring skin protection during the debridement process. Biological debridement has a narrower scope of application and is not suitable for patients with coagulation disorders or allergies to maggots.

[0003] Commonly used debridement methods include scalpel debridement, conventional irrigation debridement, autolytic debridement, mechanical debridement, enzymatic (chemical) debridement, and biological debridement.

In view of this, we propose a medical debridement hydrodynamic system. Utility Model Content

Example 2

[0028] See also Figure 5-Figure 7, a heat dissipation device 17 is provided on the inner surface of the host 1; the heat dissipation device 17 includes a PBC plate 171, the upper surface of the PBC plate 171 is fixedly connected with a U-shaped slide rail 172, the inner surface of the U-shaped slide rail 172 is slidably connected with a small motor 173, and a gear 174 is fixedly connected to the output shaft of the small motor 173, and the front surface of the U-shaped slide rail 172 is fixedly connected with a rack 175, and the gear 174 is meshed with the rack 175. The upper surface of the small motor 173 is fixedly connected with a connecting plate 176, and the front surface of the connecting plate 176 is rotatably connected with a rotating rod 177, and the outer arc surface of the rotating rod 177 is fixedly connected with a fan 178. The rotating rod 177 is connected to the output shaft of the small motor 173 through a transmission belt to ensure that the output shaft can drive the rotating rod 177 to rotate at the same time. The rotating rod 177 is fixedly connected to the output shaft of the small motor 173, and the rear surface of the connecting plate 176 is slidably connected with a slide plate 18. The upper surface of the slide plate 18 is opened The rear surface of the connecting rod 20 is hinged to the rear surface of the connecting plate 176, and the cleaning rod 21 is rotatably connected to the front surface of the connecting plate 176. The front surface of the cleaning rod 21 is rotatably connected to the vertical rod 22, and the vertical rod 22 passes through the slide plate 18 and is slidably connected to the slide plate 18. The upper surface of the slide plate 18 is provided with a groove body, and the vertical rod 22 slides in the groove body. The groove body opened by the slide plate 18 can limit the vertical rod 22 so that the vertical rod 22 can only move laterally in the groove body. The rear surface of the cleaning rod 21 is fixedly connected to a cleaning brush in a linear array. The rear surface of the host 1 is provided with a dustproof net 23. The cleaning brush of the cleaning rod 21 contacts the dustproof net 23 and can move laterally through the vertical rod 22. At the same time, the rotating rod 177 and the connecting rod 20 are pulled up and down, thereby driving the cleaning rod 21 to perform an arc motion with the rotation point as the center of the circle, thereby achieving comprehensive cleaning of the dustproof net 23;

[0029] In this embodiment, the fan 178 is driven to rotate by the output shaft of the small motor 173, and at the same time, the gear 174 and the rack 175 cooperate to drive the small motor 173, the connecting plate 176 and the fan 178 to move laterally, thereby realizing a comprehensive heat dissipation function inside the host 1. At the same time, during the heat dissipation process, the inner side of the dustproof net 23 is cleaned through the mutual cooperation of the connecting rod 20, the slide plate 18, the vertical rod 22 and the cleaning rod 21 to prevent dust from clogging the dustproof net 23 and affecting ventilation.

[0030] The operating principle involves inputting grid power through a power socket, filtering the input grid power, and then supplying it to the power module 14. This design utilizes a multi-channel serial-parallel power supply method to supply power to the subsequent control circuitry. This method ensures safe and effective isolation of the power supply components. This multi-channel power supply method allows for different required voltages, such as DC12V, DC60V, DC120V, and DC240V. Furthermore, the PM bus method effectively controls the timing of the supply voltage. The LDO voltage regulator module 15 then provides secondary isolation before supplying power to a driver IC, such as a single-chip microcomputer. The synchronous single-chip microcomputer performs PWM speed regulation, and the regulated output signal is fed to the motor driver chip, thereby controlling the motor speed. This motor speed control indirectly controls the spraying of sterile saline from the nozzle at the tip of the water jet handle. The high-speed water flow creates a cutting effect between the nozzle and the recovery straw, creating a local vacuum effect that promptly reabsorbs excised necrotic tissue fragments and biofilm. The host 1 of this system adjusts the output gear through the key input module 8 or the foot switch 2 module. The greater the corresponding output power, the stronger the cutting and re-absorption effect. The key input signal or the foot input signal is given to the single-chip microcomputer. After the single-chip microcomputer determines the source of the input signal, it outputs the corresponding gear data through the LED display. The overcurrent protection module 16 and temperature protection of this system are to monitor the output signal voltage in real time and feed it back to the corresponding peripheral integrated chip for signal identification and then give it to the single-chip microcomputer for real-time control output. The handle input recognition is to realize the handle recognition function by judging whether the handle is correctly positioned by the sensor;

[0031] When the inside of the host 1 needs to be cooled, the small motor 173 is started, and the output shaft of the small motor 173 drives the gear 174 to rotate clockwise, and the small motor 173 drives itself and the connecting plate 176 to move to the right, and at the same time drives the rotating rod 177 to rotate through the transmission belt, and the rotating rod 177 drives the fan 178 to rotate, thereby cooling the inside of the host 1. When the small motor 173 moves to the rightmost side of the rack 175, the output shaft of the small motor 173 rotates counterclockwise, driving the fan 178 to move to the left, thereby cooling the inside of the host 1. The interior of the machine 1 has the function of comprehensive heat dissipation, and when the rotating rod 177 rotates counterclockwise and clockwise, the connecting rod 20 is connected to the rotating rod 177, and the connecting rod 20 will slide in the slide groove 19 according to the rotation of the rotating rod 177. The slide plate 18 will move back and forth up and down, and the slide plate 18 drives the vertical rod 22 to move up and down through the opened groove. When the vertical rod 22 moves up and down, it will drive the cleaning rod 21 to move in an arc with the rotation point as the center of the circle, to clean the inner side of the dustproof net 23, and prevent the dustproof net 23 from being blocked.
