[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-8 As shown, a combined debridement and nursing device for an operating room comprises a transparent cover 1, characterized in that it comprises a suction head 7 arranged at the end of the transparent cover 1;

[0036] Flushing pipes 6 arranged on both sides of the suction head 7;

[0037] A pressing block 3 for pushing the suction head 7;

[0038] The locking member 21 is fixedly arranged in the transparent cover 1, and has a high groove 25 and a low groove 26 which are arranged opposite to each other and are used to limit the extension length of the suction head 7;

[0039] The plug 72 is located at the end of the suction head 7, and the gap between the plug 72 and the suction head 7 is a suction channel;

[0040] The suction head 7 makes the suction flow adjustable during the high and low position switching process.

[0041] Specifically, it also includes an ultrasonic generator 2 arranged on both sides of the transparent cover 1, which supplies physiological saline to the flushing tube 6 through a fixed liquid outlet pipe 24. The ultrasonic generator 2 is used to produce cavitation phenomenon on the physiological saline in the flushing tube 6. The transparent cover 1 is connected to a suction tube 5, and the suction tube 5 is connected to a negative pressure suction machine. The above technology is common knowledge known to those skilled in the art and will not be elaborated here.

[0042] Furthermore, the operator can hold the transparent cover 1 with one hand and adjust the pressing block 3 with fingers. The pressing block 3 is movably inserted into the transparent cover 1, and the end of the pressing block 3 is rotatably connected to the suction head 7. First, slide the pressing block 3 until it is offset from the locking member 21, and then slide along the high-position groove 25. Figure 4 As shown, during the sliding process, the distance between the suction head 7 and the plug 72 is gradually shortened, so that the suction channel becomes narrower and the flow rate is reduced. When the suction head 7 reaches the limit position of the high-level slot 25, the suction channel is completely blocked, and the device only performs the flushing effect through the flushing pipe 6. When it is necessary to adjust again, the pressing block 3 is staggered with the locking member 21, and the pressing block 3 is rotated to correspond to the low-level slot 26, and slides along the low-level slot 26 to the limit position. The suction head 7 at this position maintains a predetermined distance from the plug 72, so that the suction channel is unobstructed and the flushing pipe 6 continues to flush. Then, the fingers can be released without continuously adjusting the pressing block 3, reducing the burden on the operator. Since the ultrasonic generator 2 is arranged on the side of the transparent cover 1, the ultrasonic wave is transmitted to the transparent cover 1 through mechanical energy, and the sucked waste liquid is oscillated, which plays a role in avoiding clogging the suction head 7, and the waste liquid state can be checked in time by observing the transparent cover 1.

[0043] In the above technology, the operator can hold the transparent cover 1 with one hand and adjust the pressing block 3 with fingers to adjust the width of the suction channel, thereby changing the suction flow rate, and making timely adjustments according to the amount of exudate plasma, pus, etc. on site. The operator can also complete the two actions of flushing and suction through single-handed operation, clean the damaged surface in combination with the cavitation effect of the ultrasonic generator 2, and oscillate the sucked waste liquid.

[0044] As an embodiment further provided by the present invention, the plug block 72 is rotatably arranged relative to the suction head 7, and the plug block 72 is in a truncated cone structure that increases in size along the liquid inlet direction.

[0045] Specifically, Figure 2 As shown, a plurality of scrapers are arranged in a circular array on the plug block 72. During the liquid inlet process, the waste liquid flows into the suction head 7 along the side of the plug block 72 under the suction force. The force of the waste liquid on the scraper drives the plug block 72 to rotate, thereby generating vortexes when the waste liquid flows, further separating solid matter such as tissues and debris in the waste liquid, and scraping the suction head 7 through the rotation of the scraper to reduce blockage.

[0046] As another embodiment further provided by the present invention, it also includes a pressure rod 22 slidably disposed in the transparent cover 1 and rotatably disposed relative to the suction head 7, and a guide block 31 for guiding the deflection of the pressure rod 22 is disposed on the pressing block 3.

[0047] Specifically, the pressing block 3 is coaxially sleeved in the locking member 21, and a plurality of inclined rods cooperating with the guide block 31 are arranged in a circumferential array on the pressing rod 22. In the default state, the inclined rod is located in the high-position groove 25, at which time the plug 72 blocks the suction head 7, and then the pressing block 3 is pressed down, driving the guide block 31 to squeeze the inclined rod, and the inclined rod is deflected by the guide sliding under the tangent of the tooth grain surface of the guide block 31, so that the pressing rod 22 is deflected as a whole, and then the pressing block 3 is moved up. At this time, the deflected pressing rod 22 corresponds to the low-position groove 26, and the pressing rod 22 is slid along the low-position groove 26 to the extreme position of the low-position groove 26. At this time, a certain distance is maintained between the plug 72 and the suction head 7, so that the suction channel is stable and unobstructed, and the operator does not need to continue to press the pressing block 3.

[0048] As another embodiment further provided by the present invention, it also includes a rotating member 61 rotatably arranged at the end of the flushing tube 6 and cooperating with the suction head 7 for unidirectional rotation. A lever 62 is arranged on the flushing tube 6 to block the rotating member 61.

[0049] Specifically, Figure 8 As shown, a latch 66 is rotatably provided on the rotating member 61, and a plurality of saw teeth 74 are provided along a linear array on the suction head 7. When the suction head 7 extends in a direction away from the transparent cover 1, the saw teeth 74 will drive the latch 66 to rotate relative to the rotating member 61, and the lever 62 will block and engage with the latch 66, playing a damping role, so that the suction head 7 in the extended state can stop at different extension lengths, and because the rotating member 61 is an eccentric wheel, it will adaptively deflect with the different positions of the suction head 7 and the rotating member 61, so that the end of the flushing tube 6 keeps a distance from the suction head 7, and the suction head 7 is prevented from directly sucking the liquid out of the port of the flushing tube 6. When the suction head 7 is retracted, the saw teeth 74 no longer guide the latch 66 to rotate, reducing the obstruction when the suction head 7 is retracted.

[0050] As another embodiment further provided by the present invention, a stopper 71 is provided at the end of the suction head 7, a liquid outlet channel 63 is opened in the flushing tube 6, and there is a station for blocking the liquid outlet channel 63 in the movable stroke of the rotating member 61.

[0051] Specifically, a rolling ball 65 is provided in the liquid outlet channel 63, and a spring is provided on the rolling ball 65 for maintaining the staggered position with the liquid outlet channel 63. A transmission member 64 is also rotatably provided on the flushing tube 6 and is rotatably connected to the lever 62. When the suction head 7 is retracted, the stopper 71 is gradually driven to abut against the rotating member 61, so that the rotating member 61 deflects and squeezes the lever 62. The lever 62 will support the transmission member 64 and push the rolling ball 65 into the liquid outlet channel 63. At this time, the flushing tube 6 no longer discharges liquid, and the device only has a suction function.

[0052] As another embodiment further provided by the present invention, a converging opening 73 with an inner diameter decreasing along the liquid inlet direction is arranged in the suction head 7 .

[0053] Specifically, the operator slides and presses the block 3 until it is offset from the locking piece 21. At this time, the inclined rod is offset from the locking piece 21, and drives the suction head 7 to extend the longest distance. At this time, the plug 72 and the convergence port 73 are located at the same cross-section, and the channel formed between the convergence port 73 and the plug 72 is narrow, so that the waste liquid is accelerated when passing through the channel, and a negative pressure environment is formed due to the speed difference, thereby strengthening the suction force of the suction head 7. In addition, when the waste liquid is accelerated, the plug 72 is driven to rotate rapidly, and the tissue debris in the waste liquid is broken up by the rotation of the plug 72 to reduce agglomeration.

[0054] As another embodiment further provided by the present invention, it also includes an elastic rib 8 which is arranged in the pressure rod 22 and is used to maintain a predetermined distance between the pressure rod 22 and the guide block 31 .

[0055] Specifically, the spring tendon 8 is used to push the pressure rod 22, so that the suction head 7 maintains the tendency to retract into the transparent cover 1. In the default state, the inclined rod is located in the high-level slot 25, at which time the plug 72 blocks the suction head 7, and then the pressing block 3 is pressed down, the elastic tendon 8 contracts and accumulates force, the guide block 31 squeezes the inclined rod, and the inclined rod and the tooth grain surface of the guide block 31 are tangent to each other and deflected by the guide slide, so that the pressure rod 22 is deflected as a whole and corresponds to the low-level slot 26. At this time, let go, the stored force of the elastic tendon 8 is released and pushes the pressure rod 22, so that the inclined rod is automatically inserted into the low-level slot 26, completing the high-low position switching.

[0056] As another embodiment further provided by the present invention, a plurality of separation fins 81 facing the suction head 7 are arranged in a spiral array on the elastic rib 8; the elastic rib 8 is twisted due to the deflection of the pressure rod 22.

[0057] Specifically, the two ends of the elastic rib 8 are respectively fixedly connected to the pressure rod 22 and the guide block 31. When the pressure rod 22 deflects, since the guide block 31 is provided with a slider 32 that cooperates with the keyway of the locking member 21, the guide block 31 deflects relative to the pressure rod 22, and the elastic rib 8 twists into a spiral shape, so that the separation fins 81 are in a spiral array, and since the elastic rib 8 twists itself, the tail of the separation fin 81 is driven to expand along the tangential direction of the twisting, so as to cut and crush the tissue debris in the incoming liquid.

[0058] As another embodiment further provided by the present invention, it also includes a suction head 42 which is coaxially arranged with the elastic rib 8 and is used for sucking solid objects.

[0059] Specifically, it also includes a separation tube 41 connected to the suction head 42, and the separation tube 41 is connected to the waste bag 4. Because the elastic rib 8 is twisted in a spiral shape, combined with the scraper on the plug 72, the waste liquid forms a vortex during the suction process, and the flow rate at the center is relatively high under the action of the vortex, and due to the centrifugal force, larger tissue debris will be thrown to the periphery close to the elastic rib 8, and then chopped by the separation fin 81. The suction head 42 is provided with a unidirectional membrane, and the liquid is sucked into the waste bag 4 through the adsorption of the suction head 42, and the remaining cut tissue debris will be sucked by the suction tube 5, and the solid and liquid of the waste liquid are separated, which is beneficial to the subsequent testing and processing steps.

[0060] As another embodiment further provided by the present invention, a ring groove 28 for allowing the pressure rod 22 to be staggered with the locking member 21 is formed on the locking member 21 .

[0061] Specifically, the guide block 31 is rotatably disposed on the pressing block 3, and further includes a slide groove 27 provided on the locking member 21 for sliding the slider 32. When the operator slightly presses down the pressing block 3, the slider 32 only slides in the slide groove 27, and the inclined rod is located in the high-level groove 25 in the default state. At this time, the plug 72 blocks the suction head 7, and the stopper 71 drives the rotating member 61 to deflect, and the liquid outlet channel 63 of the flushing tube 6 is blocked.

[0062] Then, the pressing block 3 is pressed down, the elastic rib 8 contracts and accumulates force, the guide block 31 squeezes the oblique rod, and the oblique rod is deflected by the guide sliding under the tangent of the tooth grain surface of the guide block 31, so that the pressure rod 22 is deflected as a whole and corresponds to the low-level groove 26. At this time, let go, the stored force of the elastic rib 8 is released and pushes the pressure rod 22, so that the oblique rod is automatically inserted into the low-level groove 26, and a predetermined distance is maintained between the plug block 72 and the suction head 7, and the end of the flushing tube 6 is kept at a distance from the suction head 7 to prevent the suction head 7 from directly sucking the liquid out of the port of the flushing tube 6. The device sucks and flushes at the same time.

[0063] When the pressing block 3 continues to be pressed down, the slider 32 enters the annular groove 28, and the extension distance of the suction head 7 is the longest. At this time, the plug block 72 and the closing port 73 are located at the same cross-section, and the channel formed between the closing port 73 and the plug block 72 is narrow, so that the waste liquid is accelerated when passing through the channel, and a negative pressure environment is formed due to the speed difference, thereby strengthening the suction force of the suction head 7. At this time, the guide block 31 can rotate freely, and the elastic rib 8 releases its elasticity, no longer twists, and returns to the default state.

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
