The disinfectant water is sprayed to the wound position through the robotic arm 41, and the wound position is deeply disinfected, thereby achieving the positioning disinfection of the hand wound and reducing the workload of medical staff in manually performing fine treatment of the wound. When the robotic arm 41 completes the disinfection of the hand wound in sequence, the controller controls the robotic arm 41 to reset, and then the medical staff performs debridement on the wound.

[0066] As a specific embodiment of the present invention, the robotic arm 41 is further provided with a drying fan, which is connected to the actuator of the robotic arm 41 through an air pipe;

[0067] After the medical staff cleans the wound on the patient's hand and completes the cleaning and disinfection, the medical staff controls the robotic arm 41 through the controller. Under the action of the camera, the robotic arm 41 drives the actuator to move above the hand. Then the controller controls the drying fan on the robotic arm 41 to start. The drying fan inhales the air in the operating room 12 and transmits it to the actuator in the robotic arm 41 through the pipeline. The actuator blows the dry air toward the patient's hand. Since the disinfectant is oxidizing, the dry air dries up the residual disinfectant on the patient's hand to prevent the disinfectant from damaging the hand epidermis. After the hand has been dry for a period of time, the controller controls the robotic arm 41 to reset, and then the medical staff bandages the patient's hand.

[0068] Working principle of the present invention:

[0069] The medical staff puts the filled sterilization tank into the upper storage chamber 11 and the lower storage chamber 13 respectively, and connects the sterilization tank to the pipeline; then closes the cabinet door of the upper storage chamber 11 and the lower storage chamber 13, and controls the sterile air blower to start through the controller, so that the air in the operation chamber 12 is purified, and the operation chamber 12 is in a sterile environment; the patient puts the injured hand from the metal ring 123 on the single-hole panel 121 into the operation chamber 12, and puts the hand on the sterilization assembly 2, the sterilization assembly 2 opens the pipeline connecting the sterilization tank and the high-pressure gas pump under the pressure of the weight of the hand, the sterilization water in the sterilization tank is transported to the sterilization assembly 2 through the pipeline under the action of the high-pressure gas pump, the sterilization water is sprayed from the sterilization assembly 2 to the hand, and the sterilization assembly 2 immediately cleans and disinfects the hand, after a period of sterilization, the medical staff controls the sterilization tank and the high-pressure gas pump pipeline to be closed through the controller, and then the medical staff puts the metal ring 123 on the double-hole panel 122 into the operation chamber 12 to clean and treat the injured hand of the patient;

[0070] The patient puts the hand on the lower sterilization plate 212, and then the medical staff aligns the pin on the upper sterilization plate 211 with the hole on the lower sterilization plate 212, so that the upper sterilization plate 211 and the lower sterilization plate 212 are combined, the hand is placed in the sterilization plate 21, and the hand is pressed downward under the action of the weight, pressing the spray head 34, the spray head 34 presses the sliding rod 31 downward, the sliding rod 31 moves along the sliding hole 22 to one side of the placement cavity 23, in the process of moving, the sliding rod 31 drives the spray pipe 32 to move, the spray pipe 32 drives the top block 33 to move to the side close to the delivery pipe 24, when the top block 33 extends into the delivery pipe 24, the top block 33 pushes away the baffle in the delivery pipe 24, and then the gas in the high-pressure gas pump drives the sterilization water in the sterilization tank to be transmitted to the delivery pipe 24 through the pipeline, the sterilization water enters the spray pipe 32 through the delivery pipe 24, and the sterilization water is sprayed from the spray head 34 through the spray pipe 32, and the spray head 34 sprays the sterilization water in the form of water mist to the hand;

[0071] When the upper sterilization plate 211 covers the surface of the hand, the sprayer 3 contacts the upper surface of the hand, and is pressed upward under the action of the upper surface of the hand, the sprayer 3 in the upper sterilization plate 211 sprays the sterilization water downward, so that the surface of the hand is cleaned and disinfected by the sterilization water, the sterilization water in the form of water mist can penetrate into the gap of the surface of the hand, clean and disinfect the gap of the hand, and achieve the sterile effect of the hand;

[0072] After the hand is placed in the disinfection plate 21, the hand surface contacts the spherical pad 35, so that a space is formed between the hand surface and the spray head 34, avoiding the hand surface from blocking the spray head 34, causing the disinfectant water to be unable to be smoothly sprayed out, the spherical pad 35 extrudes the spray head 34 downward, and then the disinfectant water is sprayed out from the spray head 34, because the spray head 34 is arranged in a circular table shape, the disinfectant water sprayed out from the spray head 34 has different angles, increasing the contact area of the disinfectant water and the hand surface; the disinfectant water flows down along the hand and flows into the contact position of the spherical pad 35 and the hand surface, in the process of cleaning, the disinfectant water contacts the wound, which may cause pain, and then the patient subconsciously moves the hand, the hand rubs against the spherical pad 35 in the moving process, the spherical pad 35 scrapes the stains on the hand surface, and the stains mixed with the disinfectant water flow from the flow channel 36 to the surface of the disinfection plate 21;

[0073] After the disinfectant water is sprayed toward the hand surface through the spray pipe 32, the disinfectant water washes the stains and blood stains on the hand surface, the disinfectant water mixed with the blood water and the stains slides down along the surface of the hand and falls to the surface of the disinfection plate 21, the disinfectant mixed waste liquid flows along the surface of the disinfection plate 21 into the waste liquid chamber 25, and the disinfectant mixed waste liquid entering the waste liquid chamber 25 is discharged through the liquid discharge port 26;

[0074] After the disinfectant water cleans and disinfects the hand surface, the disinfectant mixed waste liquid falls to the surface of the disinfection plate 21, the surface of the disinfection plate 21 is provided with a slope surface, so that the disinfectant mixed waste liquid can quickly flow into the waste liquid chamber 25 through the slope surface, and the disinfectant mixed waste liquid flowing into the waste liquid chamber 25 converges to the center of the bottom surface of the waste liquid chamber 25 under the action of the slope and is discharged through the liquid discharge port 26;

[0075] When the cleaning and disinfection are completed, the medical staff removes the upper disinfection plate 211, and then the patient lifts the hand from the lower disinfection plate 212; at this time, the sprayer 3 in the disinfection plate 21 loses the extrusion effect of the hand, the sprayer 3 resets under the action of the spring, the top block 33 leaves the conveying pipe 24, at this time, the baffle in the conveying pipe 24 is closed under the action of the gas, and the sprayer 3 no longer sprays disinfectant water; the medical staff immediately performs debridement treatment on the wound of the patient's hand, and when the wound cleaning is completed, the hand is placed in the disinfection plate 21 for cleaning, and after the cleaning and disinfection are completed, the medical staff performs bandaging treatment on the wound;

[0076] When the patient's hand is fully cleaned by the disinfection assembly 2, the medical staff removes the disinfection assembly 2, and then starts the camera on the mechanical arm 41 by controlling the controller. The camera takes a picture of the hand and converts the picture signal into an electrical signal to the controller. The controller preliminarily locates the wound position of the hand through the electrical signal. The controller controls the effector of the mechanical arm 41 to move above the hand. When the effector of the mechanical arm 41 moves above the hand, the controller controls the infrared sensor on the mechanical arm 41 to start. The infrared sensor analyzes the temperature of the hand. Since there is a difference between the surface temperature of the hand and the temperature of the human body, the infrared sensor converts the temperature signal into an electrical signal to the controller. The controller finely locates the wound position of the hand by comparing and analyzing the difference between the temperatures. Then the controller controls the effector of the mechanical arm 41 to move to the wound position. When the effector of the mechanical arm 41 moves to the specified position, the controller controls the vacuum pump to start. The vacuum pump extracts the disinfectant water in the disinfection tank and sprays it through the effector of the mechanical arm 41. The disinfectant water is sprayed to the wound position by the mechanical arm 41 to disinfect the wound position. When the mechanical arm 41 disinfects the wound of the hand in sequence, the controller controls the mechanical arm 41 to reset. Then the medical staff performs debridement treatment on the wound.

[0077] When the medical staff debrides the wound position of the patient's hand and completes the cleaning and disinfection, the medical staff controls the mechanical arm 41 through the controller. The mechanical arm 41 moves above the hand under the action of the camera. Then the controller controls the drying fan on the mechanical arm 41 to start. The drying fan sucks the air in the operating chamber 12 and transmits it to the effector in the mechanical arm 41 through the pipeline. The effector blows dry air to the patient's hand. Since the disinfectant water has oxidizing property, the dry air blows the disinfectant water remaining on the patient's hand. When the hand is dried for a period of time, the controller controls the mechanical arm 41 to reset. Then the medical staff bandages the patient's hand.

[0078] When the medical staff completes the bandaging of the hand, the medical staff fixes the hand with a disinfection assembly 2 of a corresponding size according to the size of the injury of the hand to act as a splint. When the disinfection assembly 2 is closed, the hand presses the sprayer 3, and the sprayer 3 fixes the hand to avoid bending the hand and tearing the wound. At the same time, after the hand is fixed by the sprayer 3, there is a gap between the sprayers 3, and air can flow through the gap. When the patient's hand heals, the medical staff removes the disinfection assembly 2. The disinfection assembly 2 can be reused after disinfection.
