Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an intelligent fracture wound debridement instrument. Background Art

[0002] With the continuous advancement of medical technology, the demand for fracture wound debridement is also increasing. The intelligent fracture wound debridement instrument utilizes hydrodynamic debridement technology, which uses a high-speed, high-pressure sodium chloride injection water flow to cut wound infection and necrotic tissue, and can remove necrotic tissue more accurately and controllably while maximizing the retention of active tissue. The development of this technology makes the debridement process more refined and efficient. The safety and effectiveness of the intelligent fracture wound debridement instrument have been widely studied. Studies have shown that compared with traditional debridement methods, the use of an intelligent debridement instrument can optimize the operating process, shorten the healing time, and reduce the risk of postoperative infection. At the same time, there are also studies focusing on how to reduce potential risks in the debridement process, such as preventing the potential threat of saline atomization splashing to the health of medical staff.

The main frame includes a host, which is equipped with a microprocessor, a power adapter and various sensors. These electronic components are responsible for monitoring and controlling the working status of the equipment to ensure the accuracy and safety of the operation; the cleaning chamber is on the side of the host. The cleaning chamber is a horizontal cylindrical structure made of transparent polycarbonate material with a diameter of 20 cm and a length of 50 cm. The design of the cleaning chamber allows opening from the side away from the host to facilitate the placement of the fracture wound surface. The bottom of the cleaning chamber is designed with an interface connected to the negative pressure suction device for extracting waste liquid during the debridement process. A pipeline interface is provided on the top, which is connected to the ultrasonic debridement module to transmit the debridement fluid and guide the waste liquid.

[0031] The ultrasonic debridement module is located at the top of the cleaning chamber and consists of a controller, a regulator, an ultrasonic generator, a cylinder and a splash shield. The controller is a microcontroller that is responsible for receiving instructions from the intelligent control system and controlling the operating frequency and power of the ultrasonic generator. The regulator is located below the controller, and the two side walls are provided with a liquid inlet and outlet with a diameter of 1 cm for accurately adjusting the flow of the debridement fluid. The ultrasonic generator is located below the regulator and generates 20-40kHz ultrasonic energy for assisting debridement. The cylinder is made of stainless steel, and is provided with drainage channel 1 and drainage channel 2 running through it. A reset spring is sleeved on the outer wall of drainage channel 1 to assist in resetting the blade assembly. The splash shield is made of transparent polycarbonate material and covers the top of the cylinder to prevent the debridement fluid from splashing out.

[0032] The adjustable blade assembly is a key part of the debridement instrument, which includes a rotating rod, two rotors, a stopper, a buckle and a blade. The rotating rod is made of stainless steel, with a diameter of 1 cm and a length of 30 cm. A drainage port with a diameter of 0.5 cm is provided at the end. The rotating rod is hollow inside, and the other end is connected to the end of the drainage channel 2. The two rotors are symmetrically arranged on both sides of the rotating rod and driven by a motor to control the rotation speed and direction of the blade. The stopper is made of stainless steel and is arranged on the outside of the cylinder to limit the movement range of the blade assembly and ensure the safety of operation. The blade is made of medical stainless steel, sharp and easy to replace, and is fixed to the end of the rotating rod by a buckle.

[0033] The negative pressure suction device is composed of a bottom shell made of stainless steel, and a negative pressure source and a waste liquid tank are arranged from top to bottom inside. The negative pressure source is composed of an electric pump, which generates negative pressure and is connected to the cleaning tank through a straight suction pipe. The waste liquid tank is made of polycarbonate material, and a negative pressure gauge and a pressure regulating valve are arranged on the side surface to monitor and adjust the negative pressure. Four universal wheels are arranged at the four corners of the bottom of the bottom shell to facilitate the movement of the negative pressure suction device. The intelligent control system includes a control circuit and a user interface. The control circuit is connected to the ultrasonic debridement module and the negative pressure suction device to control and adjust their operating parameters. The user interface includes a touch screen display and physical buttons to set the debridement parameters and monitor the debridement process.

[0034] Working principle: First, place the fracture wound in the cleaning chamber, ensure that the negative pressure suction device is connected to the bottom interface of the cleaning chamber to extract waste liquid during the debridement process, and the pipeline interface at the top of the cleaning chamber is connected to the ultrasonic debridement module to transmit the debridement fluid and guide the waste liquid. The operator sets the debridement parameters, such as the frequency and power of the ultrasonic energy, the flow rate of the debridement fluid, etc., through the user interface of the intelligent control system (touch screen display and physical buttons). The control circuit of the intelligent control system receives the parameters input by the user and transmits them to the ultrasonic debridement module and the negative pressure suction device.

[0035] The ultrasonic debridement module starts working, and the controller (microcontroller) controls the ultrasonic generator to generate 20-40kHz ultrasonic energy according to the instructions of the intelligent control system to assist in debridement. The regulator accurately adjusts the flow of the debridement liquid through the liquid inlet and outlet according to the set parameters to ensure that the debridement liquid evenly covers the wound surface; the adjustable blade assembly starts working, and the rotating rod drives the blade to rotate. The blade is fixed to the end of the rotating rod by a buckle. The rotating rod is hollow inside, and the other end is connected to the drainage channel 2 to guide the waste liquid. Under the action of ultrasonic energy, the blade effectively removes foreign matter and necrotic tissue on the wound surface. At the same time, the negative pressure suction device extracts waste liquid through the suction pipe to keep the wound clean.

[0036] The electric pump in the negative pressure suction device generates negative pressure to extract the waste liquid from the cleaning chamber into the waste liquid chamber. The side surface of the waste liquid chamber is equipped with a negative pressure gauge and a pressure regulating valve to monitor and adjust the negative pressure to ensure that the waste liquid is effectively extracted without polluting the surrounding environment. Once the debridement is completed, the operator stops the device through the user interface, the device stops working, and the negative pressure suction device continues to run for a period of time to ensure that all waste liquid is extracted. The cleaning chamber and the blade assembly are cleaned and disinfected, ready for the next use.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
