Description

Technical Field

[0001] This invention belongs to the technical field of medical device cleaning equipment, specifically relating to an adjustable surgical instrument cleaning support frame. Background Technology

[0002] Adjustable surgical instrument cleaning supports are auxiliary devices specifically designed for the reprocessing of reusable surgical instruments. Their core feature is the adjustability of their structural and functional parameters. This support aims to address the poor adaptability of traditional fixed cleaning supports to instruments of different sizes, shapes, and joint structures. Through the design of movable, rotatable, or replaceable support arms, clips, pads, and spacing adjustment devices, the support can flexibly adjust the support points and fixation force according to the specific shape of the instruments (such as scissors, forceps, tubular instruments, and minimally invasive instruments). Its function extends beyond simply stabilizing instruments during cleaning, disinfection, and drying, ensuring joints are fully open to expose the articular regions, while preventing instruments from colliding with each other or contacting the cleaning basket surface, thus reducing the risk of injury. Furthermore, the appropriate support gaps optimize the circulation and penetration of water, cleaning agents, and hot air, eliminating cleaning and drying dead zones. Materials primarily consist of high-temperature resistant and corrosion-resistant medical-grade stainless steel or silicone, suitable for manual cleaning as well as fully automated spray and ultrasonic cleaning machines, significantly improving cleaning quality, instrument turnover efficiency, and infection control levels.

[0003] Existing surgical instrument cleaning support frame designs are relatively simple, typically consisting of a cleaning basket with a support frame made of stainless steel tubing. When cleaning surgical scissors, the scissors are suspended on the support frame, and the entire cleaning basket is placed in an ultrasonic cleaner for ultrasonic cleaning. However, this cleaning method cannot thoroughly clean the inner side of the scissor blade (occlusal surface) and the gaps at the joints. These areas are prone to accumulating dirt (blood, tissue), and incomplete cleaning requires repeated cleaning, otherwise the surgical outcome will be affected. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an adjustable surgical instrument cleaning support frame.

[0005] The technical solution adopted to solve the above technical problems is: an adjustable surgical instrument cleaning support frame, including a cleaning frame assembly, wherein a first fixing frame is installed on one side of the front and rear ends of the cleaning frame assembly, a slide is slidably connected to the center of the front and rear ends of the cleaning frame assembly, and a second fixing frame is slidably connected to the other side of the front and rear ends of the cleaning frame assembly. An extension mechanism is installed between one of the first fixing frames and the corresponding slide, a placement mechanism is installed at the center top of the cleaning frame assembly for suspending and supporting the surgical scissors, and a support mechanism is installed at the center of the cleaning frame assembly.

[0006] Furthermore, the cleaning rack assembly includes two support plates, each with a fixed mesh plate fixedly connected to its bottom end. Two sets of support rods are fixedly connected to the inner sides of each of the fixed mesh plates. Two sliding rods are fixedly connected to the inner side of one of the fixed mesh plates, and each sliding rod has a telescopic groove. A first fixing sleeve is fixedly connected to the other end of one set of support rods, and two telescopic rods are fixedly connected to the inner side of the other fixed mesh plate. A second fixing sleeve is fixedly connected to the other end of the other set of support rods. Multiple circular holes are formed in the center of the first and second fixing sleeves.

[0007] The above technical solution allows for adjustment of the cleaning rack assembly according to the size of the ultrasonic cleaner. Since two telescopic rods are slidably connected within corresponding sliding rods, and two sets of support rods pass through the first and second fixed sleeves respectively, with one support plate stationary, pulling the other support plate causes it, along with the connected fixed mesh plate and support rods, to move to the designated position. This means the entire cleaning rack assembly extends to approximately the same size as the ultrasonic cleaner, facilitating placement of the adjusted assembly inside the ultrasonic cleaner. Supported by the two support plates, the size of the cleaning rack assembly can be adjusted according to the size of the ultrasonic cleaner. This highly functional design caters to different ultrasonic cleaner models and is easy to use.

[0008] Furthermore, the two sets of support rods pass through the corresponding circular holes, and the two sets of support rods are slidably connected to the corresponding first and second fixed sleeves. The first and second fixed sleeves are made of rubber, and the two telescopic rods are slidably connected in the corresponding telescopic grooves.

[0009] With the above technical solution, since the first and second fixing sleeves are made of rubber, after the two sets of support rods are extended and adjusted, the first and second fixing sleeves provide a certain friction through the rubber, which can prevent the two sets of support rods from sliding under the action of no external force, thus achieving a certain fixing effect.

[0010] Furthermore, each of the multiple carriages has a first sliding groove at its center, and the multiple carriages are slidably connected to two sliding rods.

[0011] With the above technical solution, before the extension mechanism extends, multiple carriages slide on two slide rods. When the extension mechanism extends, some carriages slide on two telescopic rods, so that when the washing rack assembly extends, multiple carriages can also extend accordingly without affecting its adjustment and use.

[0012] Furthermore, a second sliding groove is provided at the center of each of the two second fixed frames, and multiple limiting grooves are provided on the inner side of each of the two second fixed frames. Similarly, before the extension mechanism extends, the two second fixed frames slide on the two sliding rods.

[0013] With the above technical solution, when the extension mechanism extends, both second fixed frames slide on the two telescopic rods.

[0014] Furthermore, the extension mechanism includes two mounting seats fixedly connected to the front end of one of the first fixed frames, a lead screw rotatably connected between the two mounting seats, a motor fixedly mounted at the bottom end of one of the mounting seats, a nut seat mounted on the lead screw, and X-shaped frames installed between the two first fixed frames and adjacent slides, between multiple slides, and between the two second fixed frames and adjacent slides. Movable pins rotatably connect to the bottom end of one side of the multiple X-shaped frames.

[0015] With the above technical solution, when the cleaning rack assembly is adjusted, the extension mechanism extends accordingly. The motor is started, and the output shaft rotates to drive the lead screw to rotate, thereby moving the nut seat. This causes the connected X-shaped frame to deform horizontally, which in turn causes the movable pin to slide in the corresponding first slide groove, thus moving the slide to the right. Since X-shaped frames are installed between multiple slides, the remaining slides are moved to the right. The distance that multiple slides move is the same, so that each row of surgical scissors suspended by the placement mechanism has a certain spacing, which facilitates thorough cleaning by ultrasonic waves.

[0016] Furthermore, the nut seat is rotatably connected to the adjacent X-shaped frame, and the plurality of movable pins are slidably connected in the corresponding first and second slide grooves.

[0017] With the above technical solution, the slide corresponding to the rear end of the cleaning rack assembly slides accordingly. After the cleaning rack assembly is adjusted, the extension mechanism can extend to the corresponding position, so that multiple suspended surgical scissors have the same spacing, thus improving cleaning efficiency.

[0018] Furthermore, the placement mechanism includes multiple rotating rods, which are rotatably connected to corresponding first fixed frames, every two slides, and two second fixed frames. Limiting rods are fixedly connected between the two first fixed frames, every two slides, and the two second fixed frames. Multiple bidirectional threaded grooves are provided on the multiple rotating rods, and slides are installed on the multiple bidirectional threaded grooves. The multiple slides are slidably connected to the corresponding limiting rods. Hooks are fixedly connected to one side of the multiple slides, and rotating heads are fixedly connected to the rear ends of the multiple rotating rods.

[0019] Through the above technical solution, since surgical scissors of different sizes have different opening angles, and there are many different types of surgical scissors in medical devices, the placement mechanism has multiple rows of hooks to hold surgical scissors of different sizes. It only needs to be adjusted. By rotating the rotating head, the connected rotating rod is driven to rotate, thereby causing each pair of slides to move in both directions. Since the surgical scissors can be suspended on the hooks by two finger rings, the greater the distance between the two hooks, the greater the opening angle of the suspended surgical scissors. Different sizes of surgical scissors have different opening angles, so they can be adjusted accordingly. This allows for thorough cleaning of the opened surgical scissors, ensuring that the inner edge of the blade and the gaps at the joint are cleaned.

[0020] Furthermore, the support mechanism includes an unwinding shaft rotatably connected to the bottom end between the two first fixed frames, and a support shaft is fixedly connected to the bottom end between each pair of carriages and the two second fixed frames. The outer wall of the unwinding shaft is wrapped with a support mesh, and a take-up shaft is installed at one end of the support mesh.

[0021] With the above technical solution, when the extension mechanism unfolds, the take-up shaft is pulled, thereby pulling the support mesh. As the unwinding shaft unwinds and the take-up shaft is pulled to the far right, the support mesh becomes taut, locking the take-up shaft into the corresponding two limiting grooves. When the support mesh is taut and laid flat on multiple support shafts, some small medical devices can be placed, allowing them to be placed in an ultrasonic cleaner for cleaning, thus achieving the classification of medical devices and facilitating their removal during cleaning.

[0022] Furthermore, the support mesh is distributed on multiple support shafts, and the take-up shaft is slidably connected between two limiting grooves.

[0023] The above technical solution allows the support mesh to be stretched according to the size of the cleaning rack assembly, and its tension can be adjusted. Simply place the take-up shaft into the corresponding two limiting slots. When the support mesh is laid flat, the cleaning rack assembly achieves a layered effect, allowing large medical devices to be placed at the bottom of the cleaning rack assembly. These devices can also be placed together in an ultrasonic cleaner for cleaning, enabling the cleaning of various medical devices and providing strong functionality.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of the cleaning rack assembly, can adjust the cleaning rack assembly according to the size of the ultrasonic cleaner, which is highly functional, meets the needs of different ultrasonic cleaner models, and is easy to use; (2) The present invention, through the design of the extension mechanism and the placement mechanism, can make the spacing between each surgical scissors placed the same through the extension mechanism, thereby improving the cleaning effect. Through the placement mechanism, the spacing between the two hooks can be adjusted, thereby adjusting the opening angle of the surgical scissors. The greater the distance between the two hooks, the greater the opening angle of the suspended surgical scissors. The opening angle of surgical scissors of different specifications is different, so it can be adjusted accordingly. (3) By designing a support mechanism, the adjusted support mesh is in a taut state, which can place some small medical devices, so that they can be placed in the ultrasonic cleaner for cleaning. After the support mesh is laid flat, the cleaning rack assembly achieves a layered effect, which allows large medical devices to be placed at the bottom of the cleaning rack assembly. They can also be placed in the ultrasonic cleaner for cleaning, thus achieving the cleaning of a variety of different medical devices. It is highly functional and convenient to take them out during cleaning. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-8As shown, an adjustable surgical instrument cleaning support frame of this embodiment includes a cleaning frame assembly 1. The cleaning frame assembly 1 includes two support plates 101. A fixed mesh plate 102 is fixedly connected to the bottom end of each of the two support plates 101. Two sets of support rods 103 are fixedly connected to the inner side of each of the two fixed mesh plates 102. Two sliding rods 104 are fixedly connected to the inner side of one of the fixed mesh plates 102. Each of the two sliding rods 104 has a telescopic groove 105. A first fixing sleeve 106 is fixedly connected to the other end of one set of support rods 103. The other fixed mesh plate 102... Two telescopic rods 107 are fixedly connected to the inner side of the first fixed sleeve 106, and a second fixed sleeve 108 is fixedly connected to the other end of the other set of support rods 103. Multiple circular holes 109 are opened in the center of the first fixed sleeve 106 and the second fixed sleeve 108, allowing the cleaning rack assembly 1 to be adjusted according to the size of the ultrasonic cleaner. Since the two telescopic rods 107 are slidably connected to the corresponding slide rods 104, and the two sets of support rods 103 pass through the first fixed sleeve 106 and the second fixed sleeve 108 respectively, with one support plate 101 stationary, pulling the other support plate 101 causes the other support plate 103 to move. The support plate 101, the connected fixed mesh plate 102, and the support rod 103 are moved and pulled to a designated position, meaning the entire cleaning rack assembly 1 extends to approximately the same size as the ultrasonic cleaner. This facilitates placing the adjusted cleaning rack assembly 1 inside the ultrasonic cleaner. Supported by two support plates 101, the size of the cleaning rack assembly 1 can be adjusted according to the size of the ultrasonic cleaner. It is highly functional, accommodating different ultrasonic cleaner models and is easy to use. The two sets of support rods 103 pass through corresponding circular holes 109. The support rod 103 is slidably connected to the corresponding first fixed sleeve 106 and second fixed sleeve 108 respectively. The first fixed sleeve 106 and second fixed sleeve 108 are made of rubber. The two telescopic rods 107 are slidably connected to the corresponding telescopic grooves 105 respectively. Since the first fixed sleeve 106 and second fixed sleeve 108 are made of rubber, after the two sets of support rods 103 are extended and adjusted, the first fixed sleeve 106 and second fixed sleeve 108 provide a certain friction through the rubber. Under no external force, the two sets of support rods 103 can be prevented from sliding, thus achieving a certain fixing effect.

[0029] like Figures 1-6As shown, a first fixed frame 2 is installed on one side of the front and rear ends of the cleaning rack assembly 1. A slide 3 is slidably connected to the center of the front and rear ends of the cleaning rack assembly 1. A second fixed frame 4 is slidably connected to the other side of the front and rear ends of the cleaning rack assembly 1. A first sliding groove 31 is opened in the center of each of the multiple slides 3. The multiple slides 3 are slidably connected to two slide rods 104. Before the extension mechanism 5 is extended, the multiple slides 3 slide on the two slide rods 104. When the extension mechanism 5 is extended, some of the slides 3 slide on the two telescopic rods 107, so that when the cleaning rack assembly 1 is extended, the multiple slides 3 can also be extended accordingly without affecting its adjustment and use. A second sliding groove 41 is opened in the center of each of the two second fixed frames 4. Multiple limiting grooves 42 are opened on the inner side of each of the two second fixed frames 4. Similarly, before the extension mechanism 5 is extended, the two second fixed frames 4 slide on the two slide rods 104. When the extension mechanism 5 is extended, the two second fixed frames 4 slide on the two telescopic rods 107.

[0030] like Figures 1-6 As shown, an extension mechanism 5 is installed between one of the first fixed frames 2 and the corresponding slide 3. The extension mechanism 5 includes two mounting seats 501 fixedly connected to the front end of one of the first fixed frames 2. A lead screw 502 is rotatably connected between the two mounting seats 501. A motor 503 is fixedly installed at the bottom end of one of the mounting seats 501. A nut seat 504 is installed on the lead screw 502. X-shaped frames 505 are installed between the two first fixed frames 2 and the adjacent slide 3, between multiple slides 3, and between the two second fixed frames 4 and the adjacent slide 3. A movable pin 506 is rotatably connected to the bottom end of one side of the multiple X-shaped frames 505. When the cleaning rack assembly 1 is adjusted, the extension mechanism 5 extends accordingly. The motor 503 is started, and the output shaft rotates to drive the lead screw 502 to rotate, thereby driving the nut seat 504 to move, thereby driving the corresponding slide 3 to move. The connected X-shaped frame 505 deforms horizontally, causing the movable pin 506 to slide in the corresponding first slide groove 31, thereby moving the slide 3 to the right. Since X-shaped frames 505 are installed between multiple slides 3, the remaining slides 3 are moved to the right, and the multiple slides 3 move the same distance, so that each row of surgical scissors suspended by the placement mechanism 6 has a certain spacing, which facilitates thorough cleaning by ultrasound. The nut seat 504 is rotatably connected to the adjacent X-shaped frame 505, and multiple movable pins 506 are slidably connected in the corresponding first slide groove 31 and second slide groove 41. The slide 3 corresponding to the rear end of the cleaning rack assembly 1 slides accordingly. After the cleaning rack assembly 1 is adjusted, the extension mechanism 5 can extend to the corresponding position, so that multiple suspended surgical scissors have the same spacing, improving cleaning efficiency.

[0031] like Figures 1-5As shown, a placement mechanism 6 is installed at the center top of the cleaning rack assembly 1. The placement mechanism 6 is used to suspend and support the surgical scissors. The placement mechanism 6 includes multiple rotating rods 601, which are rotatably connected between corresponding first fixed frames 2, every two slides 3, and two second fixed frames 4. Limiting rods 602 are fixedly connected between each of the two first fixed frames 2, every two slides 3, and the two second fixed frames 4. Each of the multiple rotating rods 601 is provided with multiple bidirectional threaded grooves 603, and each of the multiple bidirectional threaded grooves 603 is equipped with a slide 604. The multiple slides 604 are slidably connected to the corresponding limiting rods 602. A hook 605 is fixedly connected to one side of each of the multiple slides 604. A rotating head 606 is fixedly connected to the rear end of each of the multiple rotating rods 601. Since surgical scissors of different sizes have different opening angles, and there are many different types of surgical scissors in medical devices, the placement mechanism 6 is equipped with multiple rows of hooks 605 to hold surgical scissors of different sizes. It can be adjusted by rotating the rotating head 606, which drives the connected rotating rod 601 to rotate, thereby causing each pair of slides 604 to move in both directions. Since the surgical scissors can be suspended on the hooks 605 by two rings, the greater the distance between the two hooks 605, the greater the opening angle of the suspended surgical scissors. Different sizes of surgical scissors have different opening angles, so they can be adjusted accordingly. This allows for thorough cleaning of the opened surgical scissors, ensuring that the inner side of the blade (occlusal surface) and the gaps at the joint are cleaned.

[0032] like Figures 1-7As shown, a support mechanism 7 is installed at the center of the cleaning rack assembly 1. The support mechanism 7 includes an unwinding shaft 701 rotatably connected to the bottom end between two first fixed frames 2. A support shaft 702 is fixedly connected to the bottom end between each pair of slides 3 and two second fixed frames 4. A support mesh 703 is wound around the outer wall of the unwinding shaft 701. A take-up shaft 704 is installed at one end of the support mesh 703. When the extension mechanism 5 unfolds, the take-up shaft 704 is pulled, thereby pulling the support mesh 703. As the unwinding shaft 701 unwinds and the take-up shaft 704 is pulled to its rightmost end, the support mesh 703 becomes taut, locking the take-up shaft 704 into the corresponding two limiting grooves 42. When the support mesh 703 is taut and laid flat on multiple support shafts... When the support mesh 702 is in place, small medical devices can be placed inside the ultrasonic cleaner for cleaning, thus enabling the classification of medical devices and facilitating their removal during cleaning. The support mesh 703 is distributed on multiple support shafts 702, and the take-up shaft 704 is slidably connected between two limiting grooves 42. The support mesh 703 can be stretched according to the extension size of the cleaning rack assembly 1, and its tension can be adjusted. Simply lock the take-up shaft 704 into the corresponding two limiting grooves 42. When the support mesh 703 is laid flat, the cleaning rack assembly 1 achieves a layered effect, allowing larger medical devices to be placed at the bottom of the cleaning rack assembly 1. These devices can also be placed together in the ultrasonic cleaner for cleaning, enabling the cleaning of various different medical devices and providing strong functionality.

[0033] The working principle of this embodiment is as follows: the cleaning rack assembly 1 can be adjusted according to the size of the ultrasonic cleaner. Since the two telescopic rods 107 are slidably connected in the corresponding slide rods 104, and the two sets of support rods 103 pass through the first fixed sleeve 106 and the second fixed sleeve 108 respectively, one of the support plates 101 is stationary, and the other support plate 101 is pulled, so that the other support plate 101, the connected fixed mesh plate 102 and the support rod 103 move and are pulled to the designated position, that is, the size of the entire cleaning rack assembly 1 is approximately the same as the size of the ultrasonic cleaner, which makes it convenient to place the adjusted cleaning rack assembly 1 into the ultrasonic cleaner. The size of the cleaning rack assembly 1 can be adjusted by the two support plates 101 supporting it. At this time, the extension mechanism 5 is adjusted and the motor 503 is started. The output shaft rotates and drives the lead screw 502 to rotate, thereby moving the nut seat 504. This causes the connected X-shaped frame 505 to deform horizontally, which in turn causes the movable pin 506 to slide in the corresponding first slide groove 31, thereby moving the slide 3 to the right. Since X-shaped frames 505 are installed between multiple slides 3, the remaining slides 3 are moved to the right, thus adjusting the extension mechanism 5. At the same time, the rotating head 606 is rotated, thereby driving the connected rotating rod 601 to rotate, thereby causing each pair of slides 604 to move in both directions. Since the surgical scissors can be suspended on the hooks 605 by two rings, the greater the distance between the two hooks 605, the greater the opening angle of the suspended surgical scissors. The opening angle is different for different specifications of surgical scissors, so it can be adjusted accordingly. This allows for thorough cleaning of the opened surgical scissors, ensuring that the inner side of the blade (biting surface) and the gaps at the shaft joint are cleaned. When the extension mechanism 5 unfolds, the take-up shaft 704 is pulled, thereby pulling the support mesh 703. As the unwinding shaft 701 unwinds and the take-up shaft 704 is pulled to its rightmost end, the support mesh 703 becomes increasingly taut, locking the take-up shaft 704 into the corresponding two limiting grooves 42. When the support mesh 703 is taut and laid flat on multiple support shafts 702, it can hold some small medical devices, allowing them to be placed in the ultrasonic cleaner for cleaning. Furthermore, after the support mesh 703 is laid flat, the cleaning rack assembly 1 achieves a layered effect, allowing larger medical devices to be placed at the bottom of the cleaning rack assembly 1. These devices can also be placed together in the ultrasonic cleaner for cleaning, enabling the cleaning of various different medical devices. It is highly functional and convenient to handle during cleaning.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
