Description

Technical Field

[0001] The invention relates to the technical field of surgical debridement, in particular to a combined debridement and nursing device for an operating room. Background Art

[0002] Debridement care is a therapeutic measure to remove dead tissue, blood clots, foreign matter and other harmful substances from wounds or wound surfaces. It is of great significance to prevent or alleviate local infection, improve local blood circulation and promote the repair of damaged tissue. It is divided into surgical, mechanical, enzymatic and chemical debridement. Among them, surgical debridement is more common. Surgical debridement uses a scalpel and shears to remove dead tissue. It is suitable for the treatment of wounds or wound surfaces with severe tissue damage and contamination. Debridement care is usually applicable to open wounds, contaminated injuries, burns, lacerations, surgical incisions, puncture wounds, animal or human bites and infected injuries. Among them, for burns, in the case of shallow and moderate burns, debridement is required to remove the charred tissue and prevent infection.

[0003] When performing burn debridement on the patient's arm, in cases of shallow and moderate burns, the epidermal tissue on the burned area of the arm will appear scorched. The patient needs to be anesthetized first, and then medical instruments are used to remove the scorched epidermal tissue. The wound is then cleaned and disinfected, and finally medication is applied and the dressing is changed regularly.

[0004] In the prior art, when debridement is performed on burns on the arm, surgeons usually use a scalpel for excision. Since the epidermal tissue of the arm is not flat, the cutting position of the scalpel needs to be constantly adjusted when operating the scalpel. At the same time, the position of the burn area is not fixed and the direction needs to be adjusted. This operation is cumbersome and the debridement effect is poor.

[0005] In response to the above problems, there is an urgent need for innovative designs based on the original surgical debridement technology. Summary of the Invention

[0006] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technology.

[0013] Preferably, the output end of the second motor is fixed to one end of the first transmission roller, and the other end of the first transmission roller is rotatably connected to another arc-shaped plate.

The beveled edge of the cutting strip can make the front end of the cutting strip sharp and beneficial for cutting. Then, the transmission belt moves along the direction of the burn wound, and the tip of the cutting strip can be used to excise the burnt skin tissue above the pressed skin during transmission. In addition, as the curved plate moves, the cleaning liquid sprayed by the nozzle can flush the cut wound, and the cut tissue and waste liquid are discharged into the waste liquid tank through the waste outlet at the bottom of the debridement box until the cutting strip moves to the end of the wound. Compared with debridement with a scalpel, physical debridement using this method not only improves the debridement efficiency but also has a better debridement effect. In the present invention, during the excision process, a slight change in size will occur along the direction of the arm. The elastic deformation of the elastic telescopic rod can make the transmission belt always fit the patient's arm skin surface, thereby performing corresponding adaptive adjustments, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 10 The present invention provides a technical solution: a combined debridement and nursing device for an operating room, comprising a frame 1, a controller 102 mounted on the frame 1, a debridement box 2 fixed to the inner side of the frame 1, and a ring frame 3 disposed inside the debridement box 2. The device also comprises a first drive assembly disposed on the debridement box 2 for driving the ring frame 3 to move horizontally, an adjustment assembly disposed inside the ring frame 3 for adjusting the debridement angle according to the position of the wound, a second drive assembly disposed on the adjustment assembly for adaptively fitting and cleaning the wound according to the curvature of the patient's arm surface, and a cutting strip 408 disposed on the second drive assembly for arc-shaped cutting of burnt tissue. The inner side of the edge of the cutting strip 408 is provided with a bevel.

[0022] It should be noted that the first driving component can move the annular frame 3 along the direction of the arm to complete the debridement and cutting. The adjustment component can adjust the angle of the debridement and cutting according to the position of the wound on the patient's arm. The second driving component can keep the cutting strip 408 consistent with the curvature of the patient's arm when moving to cut the epidermal tissue. The edge of the cutting strip 408 is a bevel, which can make the cutting strip 408 fit the patient's arm, and the sharp front end is conducive to cutting. In addition, the cutting strip 408 can be an elastic metal sheet, so that the cutting strip 408 can also be elastically restored after bending.

[0023] The side walls of the frame 1 are rotatably connected to the side cover plates 101, the top of the debridement box 2 is rotatably connected to the top cover 201, and a waste outlet is provided at the bottom of the debridement box 2. Openings are correspondingly provided on the outer walls on both sides of the debridement box 2 and the top cover 201, and an electrically controlled clamping mechanism 202 is provided inside the opening of the debridement box 2.

[0024] It should be noted that an observation window is provided on the top cover 201, which is convenient for observing the debridement process. A waste liquid tank can be placed at the bottom of the debridement box 2, and the used cleaning liquid and resected tissue are discharged into the waste liquid tank through the waste outlet for collection. The openings on the outer walls of the debridement box 2 and the top cover 201 on both sides can facilitate the patient to place his arms in the debridement box 2, and then use the electric-controlled clamping mechanism 202 to fix the patient's arms. Because the patient's arms have no supporting force after anesthesia, the patient's wrists and upper arms need to be fixed and supported, which is conducive to the debridement process. The electric-controlled clamping mechanism 202 is a common existing technology, and the electric-controlled clamping mechanism 202 is a common center-clamping type clamping mechanism, and the electric control device in the electric-controlled clamping mechanism 202 is electrically connected to the controller 102.

[0025] The first drive assembly includes a first motor 305 fixedly mounted on the side wall of the frame 1. The output end of the first motor 305 is connected to a threaded rod 306 that passes through the interior of the debridement box 2. The threaded rod 306 is threadedly matched with the annular frame 3. A limiting rod 307 that slides with the annular frame 3 is fixed to the inner wall of the debridement box 2.

[0026] It should be noted that the first motor 305 is electrically connected to the controller 102, and the output end of the first motor 305 can be controlled by the controller 102 to rotate forward and reverse, and the first motor 305 drives the threaded rod 306 to rotate forward and reverse, and the annular frame 3 is limited by sliding on the outer wall of the limiting rod 307, so that the annular frame 3 moves along the patient's arm.

[0027] The adjustment component includes a slide rail 301 fixed to the inner side of the annular frame 3, a movable seat 302 is provided on the outside of the slide rail 301, rollers 303 are symmetrically provided on the inner wall of the movable seat 302 at equal intervals, and a positioning bolt 304 is provided on the outer wall of the movable seat 302 to cooperate with its thread.

[0028] The slide rail 301 is configured as an annular structure, and the cross section of the slide rail 301 is a T-shaped structure. The movable seat 302 is configured as a U-shaped structure, and the outer surface of the roller 303 fits the outer surface of the slide rail 301 .

[0029] It should be noted that the movable seat 302 can make circular motion on the slide rail 301. According to the position of the wound after the patient's arm is fixed, the movable seat 302 can be moved to the corresponding position, and then the positioning bolt 304 is rotated so that its end is against the outer wall of the slide rail 301 to position the movable seat 302. The outer surface of the roller 303 is in contact with the outer surface of the slide rail 301 in the horizontal direction. On the one hand, the movable seat 302 can be limited on the slide rail 301, and on the other hand, the friction resistance of the movable seat 302 when moving can be reduced.

[0030] The second driving assembly includes an elastic telescopic rod 4 fixed to the bottom of the movable seat 302, and the telescopic end of the elastic telescopic rod 4 is fixed with a connecting plate 401, and an arc-shaped plate 402 is symmetrically fixed to the bottom of the connecting plate 401, and a nozzle 403 is symmetrically provided on the outer wall of one of the arc-shaped plates 402, and a first transmission roller 404 is provided between the upper ends of the two arc-shaped plates 402, and a second transmission roller 405 is symmetrically provided between the lower ends of the two arc-shaped plates 402, and a second motor 406 is fixedly installed on the outer wall of the arc-shaped plate 402 with the nozzle 403, and the second motor 406 is used to drive the first transmission roller 404 to rotate, and a transmission belt 407 is commonly provided on the outer walls of the first transmission roller 404 and the two second transmission rollers 405, and the outer walls of the lower ends of the two arc-shaped plates 402 are symmetrically provided with a tension balance structure.

[0031] The output end of the second motor 406 is fixed to one end of the first transmission roller 404 , and the other end of the first transmission roller 404 is rotatably connected to the other arc-shaped plate 402 .

[0032] The cutting strip 408 is fixed to the outer edge of the transmission belt 407 , and the cutting strip 408 is aligned with the outer edge of the transmission belt 407 .

[0033] It should be noted that, in the initial state of the elastic telescopic rod 4, the bottom plane of the transmission belt 407 will exceed the center of the annular frame 3 by a certain distance to avoid the transmission belt 407 from covering too large an area when it fits the arm. The nozzle 403 is connected to the external liquid supply device through a hose, and the hose can be placed through the open electric clamping mechanism 202. When the nozzle 403 moves, it does not affect the electric clamping mechanism 202, and the second motor 406 and the liquid supply device are electrically connected to the controller 102 respectively.

[0034] The tension balancing structure includes a slide groove 409 opened on the outer wall of the arc plate 402 and corresponding to the end of the second transmission roller 405. A return spring 410 is fixed to the inner wall of the slide groove 409. A slider 411 that slides with the slide groove 409 is fixed to the bottom of the return spring 410. The outer walls of the slider 411 are respectively connected to the corresponding ends of the second transmission roller 405 for rotation.

[0035] The arc plate 402 is a semicircular ring structure, and the opening of the arc plate 402 faces the center of the annular frame 3 .

[0036] It should be noted that, since the transmission belt 407 is in a taut state, the transmission belt 407 will not be stretched when the plane of the transmission belt 407 forms an arc surface that fits the arm. A tension balance structure is required to ensure the tension balance of the transmission belt 407. According to the curvature and size of the patient's arm, when the transmission belt 407 is lifted up, it will pull the second transmission roller 405 so that the sliders 411 at both ends slide inside the slide groove 409, and the slider 411 squeezes the reset spring 410, wherein the elastic force of the reset spring 410 is smaller than the elastic force of the elastic telescopic rod 4, in order to make the slider 411 have the reset ability and maintain the tension of the transmission belt 407, and the opening size of the arc plate 402 is larger than that of a conventional size arm.

[0037] Working principle: When performing burn-type debridement care on the patient's arm, it is necessary to first open the side cover 101 and place the waste liquid box in the frame 1, and below the waste outlet at the bottom of the debridement box 2, so as to facilitate the collection of waste liquid and tissue generated during cleaning. Then, rotate the top cover 201 to open it and pass the hose through the electric-controlled clamping mechanism 202 of the opening, so that the nozzle 403 is connected to the external liquid supply device through the hose. After the preparation work, pass the patient's arm through the electric-controlled clamping mechanism 202 in the opening. The electric-controlled clamping mechanism 202 on one side is used to fix the wrist of the patient's arm, and the electric-controlled clamping mechanism 202 on the other side is used to fix the patient At the root position of the arm, when fixing the arm, it is necessary to push the connecting plate 401 first, and the connecting plate 401 will push the elastic telescopic rod 4 to shorten. In this state, the arm can be placed in the debridement box 2 without being blocked. After fixing the arm, the first motor 305 is controlled to rotate by the controller 102, and the first motor 305 drives the threaded rod 306 to rotate. The annular frame 3 slides on the outer wall of the limiting rod 307 for limiting, so that the annular frame 3 moves along the patient's arm. According to the starting point of the burn area on the arm, the annular frame 3 is moved to this position, and the first motor 305 is turned off, and the tip of the cutting strip 408 is facing the direction in which the wound is to be cut.

[0038] Secondly, in the above state, adjust the movable seat 302 so that it moves in a circular motion on the slide rail 301 until the bottom plane of the transmission belt 407 faces the starting side of the burn area, and then rotate the positioning bolt 304 so that its end rests against the outer wall of the slide rail 301, wherein the outer surface of the roller 303 is in contact with the outer surface of the slide rail 301 in the horizontal direction. On the one hand, the movable seat 302 can be limited on the slide rail 301, and on the other hand, the friction resistance of the movable seat 302 when moving can be reduced.

[0039] Then, the connecting plate 401 is loosened, and under the action of the elastic telescopic rod 4, the connecting plate 401 drives the arc plate 402 to move toward the patient's arm, so that the transmission belt 407 fits the surface of the arm. Since the transmission belt 407 is a non-elastic structure in the initial state and the transmission belt 407 is in a taut state, the plane of the transmission belt 407 will not be stretched when forming an arc surface that fits the arm. A tension balance structure is required to ensure the tension balance of the transmission belt 407. According to the curvature and size of the patient's arm, the transmission belt 407 is stretched. When the driving belt 407 is lifted up, it will pull the second driving roller 405 so that the sliders 411 at both ends slide inside the slide groove 409, and the sliders 411 squeeze the return spring 410. The elastic force of the return spring 410 is smaller than the elastic force of the elastic telescopic rod 4. The purpose is to make the slider 411 have the ability to reset and maintain the tension of the driving belt 407. At this time, the top cover 201 is closed and the first motor 305, the second motor 406 and the external liquid supply equipment are started. The annular frame 3 will move along the direction of the arm, and the second motor 406 will drive The first transmission roller 404 rotates at a high speed. When the transmission belt 407 is tightened, the first transmission roller 404 and the second transmission roller 405 rotate synchronously, so that the transmission belt 407 drives the cutting strip 408 to transmit synchronously, and the smooth surface of the transmission belt 407 is in contact with the skin for transmission. At the same time, the external liquid supply device causes the nozzle 403 to spray the cleaning liquid. After the annular frame 3 moves, the elastic telescopic rod 4 and the return spring 410 make the transmission belt 407 have a slight pressing force, so that the skin that is not pressed and the skin that has been pressed are pressed. When different level states appear, the transmission belt 407 moves along the direction of the burn wound and the tip of the cutting strip 408 will cut off the burnt skin tissue above the pressed skin during transmission, and as the curved plate 402 moves, the cleaning liquid sprayed by the nozzle 403 will flush the cut wound, and the cut tissue and waste liquid will be discharged into the waste liquid tank through the waste outlet at the bottom of the debridement box 2 until the cutting strip 408 moves to the end of the wound, and the first motor 305, the second motor 406 and the external liquid supply equipment are turned off.

[0040] If the cutting range is large, the position of the movable seat 302 can be adjusted, and the above steps can be repeated for the second time until the debridement is complete. Compared with the debridement with a scalpel, this method of physical debridement not only improves the debridement efficiency, but also has a better debridement effect.

[0041] Finally, during the resection process, there will be a slight change in size along the arm direction. The elastic deformation of the elastic telescopic rod 4 can make the transmission belt 407 always fit the patient's arm skin surface, thereby performing corresponding adaptive adjustments.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
