Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a debridement machine. Background Art

[0002] The debridement machine conducts liquid to the tissue, uses the cavitation effect and ultrasonic waves in the microjet to remove necrotic tissue in the wound, while protecting the granulation tissue very well and having surface and deep sterilization effects. It is mainly used to treat various types of trauma, surgical injuries, infected wounds, wound surfaces, such as burn wounds, purulent wounds / wound sinuses, fistulas, etc.; difficult-to-heal wounds, such as diabetic wounds, bedsores, neurotrophic ulcers, traumatic ulcers, etc.; soft tissue trauma, open fractures, etc.

[0003] The jet nozzles used in the debridement machines currently on the market are generally made of stainless steel for the convenience of sterilization. The shell and the amplitude rod of the jet nozzle are also installed with ultrasonic transducers and other electrical components and sealing devices. Therefore, the overall weight is heavy. During cleaning, in order to achieve the cleaning effect, the water pressure is generally relatively large. After testing, after the jet nozzle is aimed at the plastic basin, the jet can penetrate the plastic basin in about two minutes. Therefore, the doctor needs to constantly move the jet nozzle during use to avoid the jet nozzle from flushing in one position for a long time. Each flushing lasts for more than 15 minutes, which consumes the doctor's physical strength. For this reason, a debridement machine with a high degree of automation is proposed.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the form, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0023] To this end, the present invention provides a debridement machine, such as Figure 1-3 As shown, it includes a host 1, a jet nozzle 2, and a nozzle control device 3. The host 1 is provided with a waterway control system, and the waterway control system is used to transport the disinfectant to the jet nozzle 2. The nozzle control device 3 includes a bracket 31, a fixer 32, a rotating body 33, a rotating mechanism 34, an axial drive mechanism 35, a radial drive mechanism 36 and a displacement control system 37. The bracket 31 has two groups. The bracket 31 is provided with a fixer 32, and the fixer 32 is used to fix the patient's limbs. The bracket 31 has a rotating body 33 and a rotating mechanism 34, and the rotating mechanism 34 is used to control the rotation The swivel 33 rotates, and an axial driving mechanism 35 is arranged between the two swivels 33. The axial driving mechanism 35 is provided with a radial driving mechanism 36 for driving the radial driving mechanism 36 to move in the axial direction of the swivel 33. The radial driving mechanism 36 is provided with a jet nozzle 2 for driving the jet nozzle 2 to move in the radial direction of the swivel 33. The displacement control system 37 is electrically connected to the swivel mechanism 34, the axial driving mechanism 35 and the radial driving mechanism 36 respectively. The displacement control system 37 is used to record the moving path of the jet nozzle 2 and control the jet nozzle 2 to repeat the moving path.

[0024] When in use, the wound to be cleaned is placed between the two rotating bodies 33, and then the patient's limbs are fixed by two fixers 32 to prevent the patient from moving around when cleaning the wound. After fixing the limbs, the doctor manually moves the jet nozzle 2 to the wound position, and then turns on the displacement control system 37. The doctor continues to move the jet nozzle 2 in a normal cleaning manner. The displacement control system 37 records the movement path of the jet nozzle 2, and then starts the jet nozzle 2 and the waterway control system. The disinfectant is sprayed from the jet nozzle 2, and the displacement control system 37 repeats the recorded path of the jet nozzle 2. The doctor only needs to execute the first cycle, and the subsequent cycles are all controlled by the displacement control system 37 to control the rotation mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36 to achieve automatic cleaning, which is particularly suitable for cleaning wounds on the limbs.

[0025] As an embodiment of the present invention, the displacement control system 37 includes a single-chip microcomputer 371, and a storage module 372, a memory button 373, and an execution button 374 electrically connected to the single-chip microcomputer 371. The memory button 373 is used to start the position memory of the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36. The single-chip microcomputer 371 is used to receive the operation trajectory of the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36. The storage module 372 is used to store the above-mentioned operation trajectory. The execution button 374 is used to control the single-chip microcomputer 371 to drive the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36 to execute the above-mentioned operation path signal.

[0026] During operation, first move the jet nozzle 2 to the starting point of the flushing path, then start the memory button 373, and then move the jet nozzle 2 along the flushing path. The single-chip microcomputer 371 starts to memorize the operation trajectory of the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36, and writes the data of the operation trajectory into the storage module 372. After manually completing a flushing cycle, start the execution button 374. The single-chip microcomputer 371 controls the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36 according to the operation path recorded in the storage module 372 to repeat the operation path N times.

The countdown module 376 is used to stop the operation of the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36 after the countdown of the preset time is completed. The liquid level sensor 377 is arranged in the water control system to detect whether there is liquid flowing in the pipeline through which the water control system provides water flow to the jet nozzle 2. When the liquid level sensor 377 cannot detect the water flow, it means that the disinfectant has been used up, and the controller controls the rotating mechanism 34, the axial drive mechanism 35, and the radial drive mechanism 36 to stop working.

The inner ring driving wheel 343 is connected to the reduction motor 344. The reduction motor 344 is arranged on the bracket 31. The reduction motor 344 drives the rotating body 33 to rotate through the inner ring driving wheel 343.

A driving motor or a hand wheel is arranged at the end of the screw 313. The rotation of the screw 313 is controlled by the driving motor or the hand wheel, so that the distance between the two brackets 31 can be controlled, and can be adjusted according to the length of the wound.

[0033] As an embodiment of the present invention, the jet nozzle 2 is connected to the waterway control system via a spring tube 4, and the rotating mechanism 34 can only drive the rotating part to rotate one circle, thereby avoiding the problem of the spring tube 4 being entangled and affecting the water output.
