DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0021] Reference Figure 1-Figure 10A wound cleaning device for neurosurgery, comprising: an outer tube 1, a liquid extraction device 2 arranged inside the outer tube 1, an inner tube 3 arranged in the middle of the outer tube 1 and a control module 4 installed at the upper end of the inner tube 3, wherein a liquid spraying assembly 5 is arranged inside the inner tube 3, and the liquid spraying assembly comprises a sliding tube 51 and a nozzle 52, wherein the sliding tube 51 is slidingly arranged inside the inner tube 3 through an elastic member 6, and the nozzle 52 is fixedly connected to the bottom end of the sliding tube 51, and a plurality of liquid outlets are opened on the side, and the liquid outlets are arranged obliquely downward to ensure that the discharged cleaning liquid contacts the skin; The nozzle 52 is provided with an installation space inside, and a deflection assembly 7 is installed inside the installation space. The deflection assembly 7 includes a plurality of deflection seats 71, a plurality of liquid guide sheets 72 and an elastic sheet 73. The bottom of the installation space is a plane. The plurality of deflection seats 71 are fixedly connected in an annular shape inside the installation space. The plurality of liquid guide sheets 72 are fixedly connected to the upper end of the deflection seats 71 and are respectively clamped inside the plurality of liquid outlets. The liquid guide sheets 72 are fan-shaped sheets, and the plurality of liquid guide sheets form a conical disk. The plurality of elastic sheets 73 are respectively fixedly connected between the plurality of liquid guide sheets 72 to form a conical liquid guide plane. A vibration assembly 8 is disposed at the middle upper end of the deflector assembly 7, and the vibration assembly 8 is used to drive the liquid guide plate 72 to deflect up and down.

[0022] In the embodiment of applying the above technical solution, The preferred technical solution in this embodiment is: hold the outer tube 1 to operate, aim the nozzle 52 at the wound, and move the nozzle 52 along the wound. By introducing a specific cleaning liquid into the sliding tube 51, the cleaning liquid will be sprayed out along the liquid outlet during the process of the nozzle 52 spraying the cleaning liquid, forming a water knife, so as to peel off the blood scab at the wound position. The cleaning liquid will soften the blood scab during the impact peeling process, thereby facilitating the rapid peeling and cleaning of the blood scab, and reducing the pain caused by peeling. The liquid extraction device located inside the outer tube 1 will quickly extract and collect the sprayed cleaning liquid, ensuring the peeling effect while avoiding leakage of the cleaning liquid; Since the cleaning liquid is sprayed out through the liquid guide plate 72, the vibration component 8 drives multiple liquid guide plates 72 to deflect up and down during the spraying process, so that the sprayed cleaning liquid will be moved up and down. The water knife moving up and down can peel off the blood scab more quickly, thereby improving the peeling effect.

[0023] The present invention facilitates single-person operation, improves the cleaning effect, improves the peeling effect of blood scab, and simultaneously cleans the peeling position, thus avoiding secondary pollution caused by subsequent cleaning.

[0024] Reference Figure 5The liquid pumping device includes a liquid pump module 21, a guide tube 22 and a liquid pumping ring 23. The liquid pump module 21 is fixedly mounted on the upper end of the outer tube 1, and the guide tube 41 is mounted on the upper side of the liquid pump module 21. A liquid pumping space is provided inside the outer tube 1. The liquid pumping ring 23 is threadedly connected to the bottom of the outer tube 1, and the liquid is pumped into the liquid pumping space through the liquid pumping ring 23. The liquid pumping ring 23 is a truncated cone-shaped ring, and the end with a smaller area is far away from the outer tube 1. A plurality of liquid inlets are annularly opened on the inner side of the liquid pumping ring 23. A filter ring sheet 12 is arranged on the inner side of the liquid pumping ring 23. One side of the filter ring sheet 12 is fixedly connected to the inner wall of the liquid pumping ring 23 away from the liquid inlet.

[0025] During the cleaning process, the liquid extraction ring 23 contacts the cleaning position to form a sealed space inside the liquid extraction ring 23, and liquid is sprayed through the spray component 5 to clean the wound position. During the liquid spray cleaning process, the liquid extraction pump module 21 is turned on to generate a suction force moving from the bottom to the top, thereby drawing the cleaning liquid below upward. The liquid introduced into the liquid extraction ring 23 can be introduced from multiple liquid inlets on the inside of the liquid extraction ring 23. At the same time, during the cleaning process, blood clots will be mixed into the flowing liquid. During the extraction process, the blood clots will also be extracted and cleaned, reducing the number of subsequent processing steps required after cleaning.

[0026] The inverted truncated cone-shaped liquid extraction ring 23 provides a larger space for cleaning, ensuring that when the nozzle 52 rotates, the front and back of the wound can be cleaned, and the filter ring sheet 12 inside the liquid extraction ring 23 is elastic. When an upward suction force is generated, the filter ring sheet 12 will be clamped between the liquid extraction ring 23 and the liquid extraction space of the outer tube 1, thereby filtering the blood scab. When cleaning is completed, the arc-shaped filter ring sheet 12 will rebound under the action of elasticity, pushing the collected and filtered blood scab to the bottom of the liquid extraction ring 23, thereby preventing the blood scab from falling from the liquid inlet during movement, and facilitating the collection and cleaning of the blood scab.

[0027] Reference Figure 3 The bottom of the liquid pumping ring 23 is annularly fixedly connected with a plurality of sealing rings 10 , and the plurality of sealing rings 10 have different diameters and are used for multi-layer sealing at the bottom of the liquid pumping ring 23 .

[0028] Multiple sealing rings 10 can form multi-layer contact with the skin to prevent the cleaning liquid from leaking from the side of the liquid extraction ring 23 during the cleaning process. By providing multiple sealing rings 10, it can be applied to the cleaning of various wound locations, thereby improving the sealing effect.

[0029] Reference Figure 6The elastic member 6 includes two mounting rings 61 and a spring column 62. A mounting groove ring is opened in the middle of the inner side of the inner tube 3. The two mounting rings 61 are respectively fixedly connected to the upper and lower ends of the spring column 62, and are slidably arranged inside the mounting groove rings. The mounting ring 61 located above is fixedly connected to the sliding tube 51.

[0030] When the cleaning device is not in use, the nozzle 52 is located inside the inner tube 3 to reduce the external flying dust from entering the nozzle 52. During use, the nozzle 52 will be squeezed and impacted by the introduction of cleaning liquid. During the rapid introduction of the cleaning liquid, the nozzle 52 will be pushed toward the bottom of the inner tube 3. The upper end of the sliding tube 51 will drive the upper mounting ring 61 to move downward to squeeze the spring column 62. When the cleaning is completed, since there is no introduction of cleaning liquid, the sliding tube 51 is reset under the elastic action of the spring column 62, thereby moving the nozzle 52 back to the inner tube 3.

[0031] Reference Figure 7-8 The sliding tube 51 is divided into an upper fixed part and a lower rotating part by a rotating ring in the middle of the sliding tube 51. The fixed part of the sliding tube 51 is fixedly connected to the mounting ring 61, and a driving component 9 is arranged inside. The driving component 9 is used to drive the rotating part of the sliding tube 51 to rotate.

[0033] During the rapid introduction of the cleaning liquid, the flowing cleaning liquid will impact the blades 93. The inclined blades 93 will rotate under the impact of the cleaning liquid, thereby driving the telescopic rod 94 below to rotate through the mounting rod 92. The telescopic rod 94 drives the deflector assembly 7 to rotate, so that the rotating part of the sliding tube 51 rotates with the rotation of the blades 93. The rotating part of the rotating sliding tube 51 will drive the nozzle 52 to rotate, so that the sprayed cleaning liquid forms a plurality of rotating water knives, which peel off the blood scab at the wound position from multiple directions from front and back.

[0034] At the same time, the introduction speed of the cleaning liquid can be controlled according to the needs of use, thereby controlling the rotation speed of the water jet.

The vibration rod 81 is vertically fixedly connected in the middle of the liquid guide plane, the extrusion ring 82 is fixedly connected to the upper end of the vibration rod 81, the bottom end of the telescopic rod 94 is fixedly connected to the extrusion ring 82, and the push rod 83 is L-shaped, the upper end of which is fixedly connected to the inner wall of the fixed part of the sliding tube 51, and the bottom end is in contact with the extrusion ring 82.

[0036] An arc-shaped protrusion is provided on one side of the extrusion ring 82 , and the extrusion ring 82 contacts the abutment rod 83 during rotation, thereby driving the vibration rod 81 to move up and down.

[0037] During the rotation of the telescopic rod 94, the extrusion ring 82 will be driven to rotate, while the push rod 83 is fixed to the fixed part of the sliding tube 51. During the rotation of the extrusion ring 82, the push rod 83 will not rotate. An arc-shaped protrusion is provided on the extrusion ring 82. During the rotation of the extrusion ring 82, the arc-shaped protrusion will intermittently contact the push rod 83, thereby driving the vibration rod 81 to move up and down intermittently. During the up and down movement of the vibration rod 81, the liquid guide plane will be depressed inward, thereby forming water knives sprayed at different angles. The water knives sprayed in an up and down wavy shape will soften and peel off the blood scab at the wound position, reducing the peeling pain while speeding up the peeling efficiency of the blood scab.

[0038] Reference Fig.10 The control module 4 includes a liquid guide tube 41 and a control panel 42. The control panel 42 is fixedly installed on the upper end of the inner tube 3 and is provided with a plurality of buttons. The liquid guide tube 41 is fixedly installed in the middle of the control panel 42 and is connected to the inner tube 3 for guiding liquid.

[0039] The introduction of the cleaning liquid and the introduction speed of the cleaning liquid in the liquid guiding tube 41 are controlled by the control panel 42, and automatic control is performed according to the use requirements. It can be operated with one hand, which facilitates cleaning and improves cleaning efficiency.
