Description

Technical Field

[0001] This invention relates to the field of instrument cleaning technology, and in particular to an instrument rinsing device for neurosurgical procedures. Background Technology

[0002] In neurosurgery, a large number of instruments such as scalpels and scissors are used. During the operation, these instruments will be covered with bloodstains, biological debris and other debris, which need to be cleaned using a rinsing device.

[0003] The existing technology has the following problems: Existing cleaning equipment often uses a stirring structure to accelerate the mixing of cleaning solutions and prevent debris from accumulating around instruments, thus preventing the medication from reaching the instruments. In order to avoid the stirring structure affecting surgical instruments during operation, such as occupying space or causing contact and impact, the volume of the stirring structure is minimized as much as possible. This often results in dead corners in the stirring structure, where some small debris particles may accumulate during the cleaning process and are difficult to clean. Summary of the Invention

[0004] The main objective of this invention is to provide an instrument rinsing device for neurosurgical procedures, which can effectively solve the problem of difficult-to-clean debris in the four corners.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An instrument irrigation device for neurosurgery includes an irrigation box with four rectangular support feet on its lower side. The upper side of the irrigation box has a flip-top for closing, and a pressure relief valve on the upper side of the flip-top. Several irrigation mechanisms distributed front-to-back are fixedly connected to the inner side of the irrigation box, as are a fixing mechanism and two placement mechanisms distributed vertically.

[0006] Preferably, the rinsing mechanism includes an aeration pipe with mounting plates at both ends. The mounting plate on the left side is fixed to the left side of the aeration pipe by means of a snap-fit ​​mechanism. An isolation mesh is movably sleeved on the outer side of the aeration pipe. A fixing seat for inserting and removing the isolation mesh is fixedly connected to the side of each of the two mounting plates that are close to each other. An adjusting component is rotatably connected to the outer side of each of the two mounting plates. Several ring-shaped clamping blocks are slidably connected to the side of each of the two adjusting components that are close to each other. A clamping groove is opened on the side of each of the clamping blocks that is away from the adjusting component. An isolation plate is movably sleeved on the inner side of each of the clamping grooves. Adjacent isolation plates are fixed together by connecting strips. All the isolation plates and connecting strips are arranged in a ring array to form an expandable and contractible cylindrical component.

[0007] The fixing mechanism includes a slide table, the outer side of which is slidably connected to the inner wall of the cleaning box, and two electric push rods for moving the slide table left and right are fixedly connected to the side of the slide table away from the rinsing mechanism.

[0008] The adjustment assembly includes a rotating plate, the inner side of which is rotatably connected to the outer side of the mounting plate. The side of the clamping block away from the isolation plate is slidably connected to the side of the rotating plate near the aeration pipe via multiple round shafts that can maintain the movement of the clamping block. The outer side of the mounting plate is rotatably connected to a guide plate, one of which is slidably connected to an arc-shaped groove on the guide plate to stabilize the movement of the clamping block.

[0009] The upper side of the slide is fixedly connected to several first jet pipes distributed front and back, and the inner side of the cleaning box is fixedly connected to several second jet pipes distributed front and back. Each rinsing mechanism is driven to rotate by two first jet pipes and two second jet pipes. The outer side of the guide plate is fixedly connected to several ring-shaped blades, and the guide plate is driven to rotate by the first jet pipes and second jet pipes by the blades.

[0010] A fixing plate is fixedly connected to the side of the mounting plate away from the aeration pipe. A rod is movably fitted into the round hole on the guide plate to restrict the space between the guide plate and the rotating plate. A first connecting plate is provided on the side of the rod away from the aeration pipe to synchronously move all the rods. An electromagnetic telescopic rod for driving the first connecting plate is fixedly connected to the fixing plate. The electromagnetic telescopic rod and the first connecting plate are connected by a plate rotation connection.

[0011] The placement mechanism includes a placement box, with two mounting brackets slidably connected to the lower side of the placement box for supporting the placement box. The outer sides of the mounting brackets are fixedly connected to the inner side of the cleaning box, and the placement box is located on the upper and lower sides of the rinsing mechanism. The rinsing mechanism can perform cleaning operations on the two placement boxes simultaneously. Several rotating rods are rotatably connected to the inner side of the placement box, and transmission rods are fixedly connected to both ends of the rotating rods. Placement nets are fixedly connected between adjacent rotating rods. The two sides of the placement nets are flexibly connected to the inner side of the placement box using flexible sheets. The placement nets can swing back and forth under the placement box through the flexible sheets without any gaps.

[0012] A second connecting plate is fixedly connected to the side of the first connecting plate near the aeration pipe. The electromagnetic telescopic rod drives the second connecting plate while driving the first connecting plate. The outer side of the second connecting plate is movably sleeved on the inner side of the guide plate. Several annularly distributed push rods for driving the transmission rod are rotatably connected to the side of the second connecting plate near the aeration pipe. The outer side of each push rod is movably sleeved in a circular hole opened on the side of the rotating plate. Disengagement grooves are opened on the outer side of each push rod to prevent the push rod from contacting the transmission rod.

[0013] The inner side of the cleaning box is fixedly connected to a rotating seat for detachable rotational connection with the right-side mounting plate. The side of the mounting plate on the left side away from the aeration pipe is movably connected to a clamping plate that synchronously pulls all the right-side mounting plates via a clamping shaft. A ventilation hose is fixedly connected to the lower side of several rotating seats.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides an instrument irrigation device for neurosurgical procedures. Based on the cooperation of a first air jet pipe, a second air jet pipe, an irrigation mechanism, an aeration pipe, a mounting plate, a retaining seat, an isolation mesh, an adjustment component, a rotating plate, a guide plate, blades, a fixing plate, an electromagnetic telescopic rod, a first connecting plate, a plug rod, a clamping block, an isolation plate, a rotating seat, and a clamping groove, air is sprayed through the first and second air jet pipes on one side near the guide plate, causing the guide plate and the rotating plate to rotate in the same or opposite directions. This causes the isolation plate to converge or expand, thereby agitating the medication and opening up narrow gaps through the expansion effect, preventing the accumulation of small particles that are difficult to clean.

[0015] 2. This invention provides an instrument irrigation device for neurosurgical procedures. Based on the cooperation of an irrigation mechanism, a fixing mechanism, a clamping plate, a slide, an electric push rod, a first air jet pipe, a second air jet pipe, a placement mechanism, a clamping plate, and a placement box, the electric push rod drives the clamping plate to move, thereby fixing the placement box and the irrigation mechanism, and simultaneously resetting the first air jet pipe. This avoids interference with the installation of the device and allows the fixing of the device after assembly to be completed in one step.

[0016] 3. This invention provides an instrument rinsing device for neurosurgical procedures. Based on the cooperation of the placement box, rotating rod, placement net, transmission rod, push rod, second connecting plate and dislocation groove, in the expanded state, the push rod pushes the transmission rod to swing, causing the placement net to swing, thereby avoiding the difficulty in cleaning the parts of the placement net that are in contact with the instrument, making the cleaning more thorough.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1: like Figures 1-11 As shown, a rinsing device for instruments in neurosurgery includes a rinsing box 1. The lower side of the rinsing box 1 is provided with four rectangularly distributed support feet 2 for support. The upper side of the rinsing box 1 is provided with a flip cover 7 for closing. The upper side of the flip cover 7 is provided with a pressure relief valve 3 for pressure relief. Several rinsing mechanisms 4 distributed front and back are fixedly connected to the inner side of the rinsing box 1. A fixing mechanism 5 is fixedly connected to the inner side of the rinsing box 1. Two placement mechanisms 6 distributed vertically are fixedly connected to the inner side of the rinsing box 1. It should be noted that during operation, first open the flip cover 7, pull the clamp plate 51 to make the aeration tube 41 vertical, then put it into the bottom clamping platform 61, place the medical device inside, reset the aeration tube 41 so that the fixing mechanism 5 fixes the rinsing mechanism 4, then put it into the top clamping platform 61, place the medical device inside, close the flip cover 7. The bottom of the front and rear sides of the cleaning box 1 is provided with liquid inlet and liquid outlet. The cleaning solution is introduced into the cleaning box 1 through the liquid inlet. The external air pump makes the rinsing mechanism 4 and the fixing mechanism 5 work together to clean the medical device. After cleaning, the used cleaning solution is discharged from the outlet, and new cleaning solution is injected for a second cleaning to prevent small particles from adhering to the equipment surface. After the second cleaning, clean water is injected when the cleaning solution is discharged to ensure that small particles are removed as much as possible. The pressure relief valve 3 is used to prevent excessive air pressure in the cleaning box 1 due to the air pump injecting gas. If necessary, a component for ultrasonic cleaning can be installed in the cleaning box 1 to further improve the cleaning efficiency.

[0021] Example 2: The flushing mechanism 4 includes an aeration pipe 41, with mounting plates 42 at both ends of the aeration pipe 41. The mounting plate 42 on the left side is fixed to the left side of the aeration pipe 41 by means of a snap-fit. An isolation screen 44 is movably sleeved on the outside of the aeration pipe 41. A fixing seat 43 for inserting and removing the isolation screen 44 is fixedly connected to the side of the two mounting plates 42 that are close to each other. An adjusting component 45 is rotatably connected to the outside of the two mounting plates 42. Several ring-shaped clamping blocks 46 are slidably connected to the side of the two adjusting components 45 that are close to each other. A clamping groove 412 is opened on the side of the several clamping blocks 46 that are away from the adjusting component 45. An isolation plate 47 is movably sleeved on the inner side of the several clamping grooves 412. Adjacent isolation plates 47 are fixed by connecting strips. All the isolation plates 47 and the connecting strips form a ring array to form an expandable and contractible cylindrical component. The placement mechanism 6 includes a placement box 62, and two mounting platforms 61 for supporting the placement box 62 are slidably connected to the lower side of the placement box 62. The outer sides of the mounting platforms 61 are fixedly connected to the inner side of the cleaning box 1, and the placement box 62 is located on the upper and lower sides of the rinsing mechanism 4. The adjustment assembly 45 includes a rotating plate 451, the inner side of which is rotatably connected to the outer side of the mounting plate 42. The side of the clamping block 46 away from the isolation plate 47 is slidably connected to the side of the rotating plate 451 near the aeration pipe 41 by a plurality of round shafts that can keep the clamping block 46 in a movable state. The outer side of the mounting plate 42 is rotatably connected to a guide plate 452, one of which is slidably connected to an arc-shaped groove on the guide plate 452 to stabilize the movable state of the clamping block 46. Several first jet pipes 54 distributed front and back are fixedly connected to the upper side of the slide table 52, and several second jet pipes 55 distributed front and back are fixedly connected to the inner side of the cleaning box 1. Each rinsing mechanism 4 is driven to rotate by two first jet pipes 54 and two second jet pipes 55. Several ring-shaped blades 453 are fixedly connected to the outer side of the guide plate 452. The guide plate 452 is driven to rotate by the first jet pipes 54 and the second jet pipes 55 by the blades 453. A fixing plate 454 is fixedly connected to the side of the mounting plate 42 away from the aeration pipe 41. A rod 457 that restricts the space between the guide plate 452 and the rotating plate 451 is movably sleeved in the round hole on the guide plate 452. A first connecting plate 456 that moves all rods 457 synchronously is provided on the side of the rod 457 away from the aeration pipe 41. An electromagnetic telescopic rod 455 for driving the first connecting plate 456 is fixedly connected to the fixing plate 454. At the same time, the electromagnetic telescopic rod 455 and the first connecting plate 456 are connected by plate rotation. It should be noted that the first jet pipe 54 and the second jet pipe 55 are located on the front and rear sides of the guide plate 452, and are symmetrically distributed on the front and rear sides of the guide plate 452. The isolation plate 47 has two states. In the first state, the isolation plates 47 are cleaned and brought closer together. At this time, the first jet pipe 54 and the second jet pipe 55 on the same side, as well as the ventilation hose 413, are supplied with clean gas by an external air pump. When the ventilation hose 413 is ventilated, the gas enters the aeration pipe 41, causing the surface of the aeration pipe 41 to spray gas outward. Due to the structural shape of the isolation plates 47, the cylindrical component composed of multiple isolation plates 47 rotates. When the first jet pipe 54 and the second jet pipe 55 spray gas to blow the blades 453, they drive the guide plate 452 to rotate. The rotation direction of the guide plate 452 is the same as that of the isolation plates 47, but their rotation speeds are different. The guide plate 452 rotates faster. Due to the arc groove on the guide plate 452, the round shaft on the clamping block 46 is driven, causing the clamping block 46 to slide in the arc groove, thereby causing the clamping blocks 46 to move closer together. In order to maintain the stability of the clamping block 46, the circular shafts on the clamping block 46 are not in the same straight line. The sliding groove on the rotating plate 451 for the circular shaft to slide is arc-shaped, so that the clamping block 46 will not change its posture when the isolation plate 47 and the connecting bar are contracted and the two sides of the connecting bar are rotating on the isolation plate 47. In order to stabilize the rotating plate 451 and the guide plate 452, after the isolation plate 47 and the connecting strip are fully retracted, the electromagnetic telescopic rod 455 drives the first connecting plate 456 to move, so that the insertion rod 457 moves on the guide plate 452. The insertion rod 457 moves to the side closer to the aeration pipe 41, so that the insertion rod 457 is inserted into the slot on the side of the rotating plate 451 away from the aeration pipe 41, so that the rotating plate 451 and the guide plate 452 remain relatively stationary, and at the same time the first jet pipe 54 and the second jet pipe 55 no longer ventilate. In the second state, the isolation plate 47 is cleaned. The electromagnetic telescopic rod 455 drives the insertion rod 457 to disengage from the slot. The first jet pipe 54 and the second jet pipe 55, which are not operating in the first state, are ventilated, so that the guide plate 452 and the isolation plate 47 rotate in opposite directions, thereby causing the isolation plate 47 and the connecting strip to expand, so that the slit formed by the isolation plate 47 and the connecting strip is opened. The isolation plate 47 and the connecting strip are made of polypropylene, which allows the connecting strip and the isolation plate 47 to rotate repeatedly. When the isolation plate 47 and the connecting strip are closed, a narrow slit is formed. This makes the surface of the cylindrical component composed of the isolation plate 47 and the connecting strip curved, which facilitates stirring of the liquid medicine when rotating. At the same time, the gas sprayed from the aeration pipe 41 also has a stirring effect. To facilitate the assembly and disassembly of components, the card holder 43 has an insertion hole on the side away from the mounting plate 42. The inside of the card holder is similar to the inside of the clamping groove 412, and both are provided with elastic clips to fix the outer ends of the isolation plate 47 and the isolation mesh 44. The aeration pipe 41 is used to spray air to achieve a rinsing effect on the instruments. The isolation screen 44 is used to prevent external debris from falling into the spray holes on the aeration pipe 41. The isolation plate 47 is used to protect the isolation screen 44 and prevent the instruments to be cleaned from damaging the isolation screen 44.

[0022] Example 3: The fixing mechanism 5 includes a slide table 52, the outer side of which is slidably connected to the inner wall of the cleaning box 1, and two electric push rods 53 for driving the slide table 52 to move left and right are fixedly connected to the side of the slide table 52 away from the rinsing mechanism 4. The inner side of the cleaning box 1 is fixedly connected to a rotating seat 411 for detachable rotational connection with the right side mounting plate 42. The side of the left side mounting plate 42 away from the aeration pipe 41 is movably connected to a clamping plate 51 that synchronously pulls all the right side mounting plates 42 via a clamping shaft. A ventilation hose 413 is fixedly connected to the lower side of several rotating seats 411. It should be noted that the electric push rod 53 is used to drive the slide table 52 to move left and right. When the slide table 52 moves left and right, the first jet pipe 54 moves left and right. When the first jet pipe 54 moves to the left, it will not interfere with the placement of the lower mounting box 62. When the slide table 52 moves to the far right, the vertical wall of the slide table 52 is in contact with the clamping plate 51, so that the clamping plate 51 is fixed. The top block on the vertical wall of the slide table 52 contacts the mounting box 62, so that the mounting box 62 is fixed. The clamping plate 51 is synchronously linked to all the rinsing mechanisms 4, so that when the clamping plate 51 is pulled, all the mounting plates 42 on the side away from the fixing mechanism 5 rotate on the rotating seat 411. The mounting plates 42 on the side away from the fixing mechanism 5 are fixedly connected to the aeration pipe 41. The clamping shaft is fixedly connected to the side of the aeration pipe 41 away from the rotating seat 411, so that the aeration pipe 41 is movably sleeved with the mounting plate 42 on the side away from the rotating seat 411 through the clamping shaft. The outer side of the clamping shaft is movably sleeved in the hole on the clamping plate 51.

[0023] Example 4: The placement mechanism 6 includes a placement box 62. Two mounting platforms 61 for supporting the placement box 62 are slidably connected to the lower side of the placement box 62. The outer sides of the mounting platforms 61 are fixedly connected to the inner side of the cleaning box 1. The placement box 62 is located on the upper and lower sides of the rinsing mechanism 4. The rinsing mechanism 4 can perform cleaning operations on the two placement boxes 62 at the same time. Several rotating rods 63 are rotatably connected to the inner side of the placement box 62. Both ends of the several rotating rods 63 are fixedly connected to the transmission rods 65. A placement net 64 is fixedly connected between adjacent rotating rods 63. The two sides of the placement net 64 are flexibly connected to the inner side of the placement box 62 by a flexible sheet. The placement net 64 can swing back and forth under the placement box 62 through the flexible sheet, and there are no gaps between them. A second connecting plate 49 is fixedly connected to the side of the first connecting plate 456 near the aeration pipe 41. The electromagnetic telescopic rod 455 drives the second connecting plate 49 while driving the first connecting plate 456. The outer side of the second connecting plate 49 is movably sleeved on the inner side of the guide plate 452. Several annularly distributed push rods 48 for driving the transmission rod 65 are rotatably connected to the side of the second connecting plate 49 near the aeration pipe 41. The outer side of the push rod 48 is movably sleeved in the round hole opened on the side of the rotating plate 451. The outer side of each push rod 48 is provided with a disengagement groove 410 to prevent the push rod 48 from contacting the transmission rod 65. It should be noted that the flexible sheet can be made of rubber. In the first state of Embodiment 2, the dislocation groove 410 is aligned with the transmission rod 65 so that the push rod 48 will not contact the transmission rod 65. In the second state, the movement of the first connecting plate 456 will drive the second connecting plate 49, causing the second connecting plate 49 to pull the push rod 48 to move closer to the electromagnetic telescopic rod 455, so that the outer side of the push rod 48 can contact the transmission rod 65. When the rotating plate 451 rotates, it will drive the push rod 48 to contact the transmission rod 65 in turn. A torsion spring is provided between the rotating rod 63 and the placement box 62 to keep the transmission rod 65 vertical. After the push rod 48 contacts the transmission rod 65, it will drive the rotating rod 63 to rotate, causing the rotating rod 63 to twist the placement net 64 back and forth. This will cause the instruments placed on the placement net 64 to move slightly, preventing the parts of the instruments that are in contact with the placement net 64 from being difficult to clean.

[0024] The working principle of this invention is as follows: First, the first jet pipe 54, the second jet pipe 55, and the ventilation hose 413 generate air by means of an external air pump, causing the guide plate 452 and the isolation plate 47 to rotate. When the guide plate 452 and the rotating plate 451 rotate in the same direction, the isolation plate 47 retracts, and then the isolation plate 47 is in a stirring state. When the guide plate 452 and the rotating plate 451 rotate in opposite directions, the isolation plate 47 expands, causing the isolation plate 47 to be in a cleaning state. The insertion rod 457 is moved by the electromagnetic telescopic rod 455, so that after the isolation plate 47 is adjusted to the retracted state, it fixes the rotating plate 451 and the guide plate 452, preventing the retracted state of the isolation plate 47 from being unstable. The first jet pipe 54 and the second jet pipe 55 on one side near the guide plate 452 generate air by means of an external air pump, causing the guide plate 452 and the isolation plate 47 to rotate. The jet nozzle 55 sprays air, causing the guide plate 452 and the rotating plate 451 to rotate in the same or opposite directions, thereby causing the isolation plate 47 to converge or expand. This allows the isolation plate 47 to agitate the liquid and open up narrow gaps through expansion, preventing the accumulation of small particles that are difficult to clean. Then, the electric push rod 53 drives the clamping plate 51 to move, fixing the placement box 62 and the rinsing mechanism 4. At the same time, the first jet nozzle 54 is reset, thus preventing interference with equipment installation and allowing the fixing of the equipment after assembly to be completed in one step. Finally, in the expanded state, the push rod 48 pushes the transmission rod 65 to swing, causing the placement net 64 to swing, thus preventing the parts of the placement net 64 that are in contact with the instrument from being difficult to clean, making the cleaning more thorough.
