Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and in particular to an auxiliary disinfection tool. Background Technology

[0002] In the medical field, the sterilization of surgical instruments is of paramount importance, directly affecting the patient's postoperative infection risk and the quality of medical care. Surgical forceps, as a commonly used surgical instrument, frequently come into contact with contaminants such as the patient's blood and tissues during surgery. The sterilization supply room is responsible for the cleaning, sterilization, and disinfection of surgical instruments, and the sterilization of surgical forceps is a key step in this process.

[0003] Traditional surgical forceps sterilization procedures typically include pretreatment, manual scrubbing, mechanical cleaning, sterilization, and drying. However, in practice, the teeth of surgical forceps are finely interlocked, and there are multiple overlapping structures at the joints. It is difficult to completely open the instruments during manual scrubbing, and residual blood and tissue fluid can easily form biofilms, becoming sterilization blind spots. Residual organic matter provides a good environment for the survival and reproduction of bacteria, viruses, and other microorganisms. Even after subsequent sterilization steps, the large-scale growth of microorganisms may lead to incomplete sterilization, greatly increasing the risk of postoperative infection for patients.

[0004] Currently, there are some improved equipment and methods for cleaning and disinfecting surgical instruments on the market. For example, some high-end mechanical cleaning equipment uses high-pressure pulsed water flow technology, attempting to clean complex parts of instruments through powerful water jet impact. However, such equipment is not only expensive, but also may damage delicate instruments like surgical forceps due to excessive water pressure. It also cannot solve the problem of cleaning dead spots caused by the forceps not being fully opened. There are also some auxiliary cleaning tools, such as specially designed brushes, but these tools still rely on manual operation, making it difficult to guarantee the uniformity and stability of the brushing force, and failing to fundamentally solve the problem of residue. Therefore, developing a simple, efficient, low-cost disinfection auxiliary device that can effectively solve the problem of blood or tissue residue at the teeth and joints of surgical forceps is of great practical significance. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this invention is to provide an auxiliary disinfection tool that effectively solves the problem of blood or tissue residue at the teeth and joints of surgical forceps when disinfecting them in existing sterilization supply rooms due to incomplete opening of the instruments or insufficient scrubbing force.

[0006] The technical solution is as follows: The present invention includes an upward-opening box body, with horizontal plates slidably connected to the front and rear side walls of the box body, and two horizontal plates are fixedly connected by a connecting plate. The connecting plate can drive the two horizontal plates to move up and down. Multiple support plates are fixed on the rear horizontal plate and distributed along the left and right directions. A notch is opened on the front side of the support plate, and a horizontal axis with a left and right axis is fixed in each notch. Two swing plates are rotatably connected on each horizontal axis. Each pair of adjacent swing plates forms an X-shape and can swing relative to or away from each other. Y-shaped clamping blocks with a left and right direction are fixed on the left and right sides of each swing plate. The openings of each pair of left and right opposite clamping blocks are set in opposite directions. Sliding holes are connected to the front and rear sides of the opening of the clamping block. A locking post is connected to the bottom of the sliding hole by a first spring. The free end of the locking post is a spherical surface and extends into the opening of the clamping block. Positioning posts are fixed on the left and right sides of the upper end of each swing plate.

[0007] Between the two horizontal plates is a pivot shaft that can rotate in both directions along a front-to-back axis. The pivot shaft has two opposite threaded grooves with opposite spiral directions. Each threaded groove is threaded to a horizontal bar in the left-to-right direction. Multiple U-shaped frames, each corresponding to a clamping block and with their openings facing backward, are fixed on the front horizontal bar. The U-shaped frames are located directly to the left or right of the adjacent horizontal axis. Multiple stiff bristles are fixed inside each U-shaped frame. The box contains a silicone strip located directly below the horizontal axis in the left-to-right direction. The silicone strip can move left and right, and multiple soft bristles are fixed on its front and back sides. When the connecting plate moves downward to its limit, every two adjacent swing plates start to drive the surgical forceps to swing back and forth relative to each other or in opposite directions. The angle at the joint of the surgical forceps shaft repeatedly increases and decreases. At the same time, the U-shaped frames start to move back and forth, and the silicone strips start to move left and right, thus achieving the brushing of the joint of the surgical forceps shaft and the teeth.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] Through the cleverly designed structure of swing plate, clamping block and moving rack, the angle of the surgical forceps shaft joint can be repeatedly increased and decreased, so that the cleaning dead corners formed due to incomplete opening can be fully exposed. With the hard bristles on the U-shaped frame and the soft bristles on the silicone strip, the surgical forceps shaft joint and forceps teeth can be thoroughly and repeatedly brushed, effectively removing blood, tissue and other residues, significantly improving the disinfection effect and reducing the risk of postoperative infection for patients.

[0010] Driven by a motor and combined with transmission components such as intermittent gears, arc racks, and power gears, a series of operations such as automatic opening and closing of surgical forceps and automatic movement of brushing components are realized during the disinfection process. This eliminates the need for extensive manual intervention, reduces the labor intensity of operators, and simplifies the operation process.

[0011] Compared to high-pressure pulsed water flow technology and other equipment, this invention adopts a relatively gentle mechanical brushing method, which ensures the cleaning effect while avoiding damage to delicate instruments such as surgical forceps due to excessive pressure, thus extending the service life of the instruments.

[0012] Compared with traditional auxiliary cleaning tools such as brushes that rely on manual operation, this invention can ensure the uniformity and stability of the brushing force, avoid the problem of inconsistent cleaning results caused by differences in manual operation, and ensure that every surgical forceps can be reliably sterilized. The structure is reasonably designed and the overall manufacturing cost is low. At the same time, the automated operation reduces labor costs and is suitable for various medical institutions.

[0025] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Depend on Figures 1 to 12 The device includes an upward-facing box 1. Horizontal plates 2 are slidably connected to the front and rear side walls of the box 1. The two horizontal plates 2 are fixedly connected by a connecting plate 3. The connecting plate 3 can drive the two horizontal plates 2 to move up and down. Multiple support plates 4 are fixed on the rear horizontal plate 2, distributed in the front-back direction and along the left-right direction. The front side of the support plate 4 has a notch. A horizontal axis 5 is fixed in each notch. Two swing plates 6 are rotatably connected to each horizontal axis 5. Each pair of adjacent swing plates 6 forms an X-shape and can swing relative to or away from each other. Y-shaped clamping blocks 7 are fixed on the left and right sides of each swing plate 6. The openings of each pair of left-right opposing clamping blocks 7 are set away from each other. Sliding holes are connected to the front and rear sides of the opening of the clamping block 7. The bottom of the sliding hole is connected to a locking post 9 via a first spring 8. The free end of the locking post 9 is a spherical surface and extends into the opening of the clamping block 7. Positioning posts 10 are fixed on the left and right sides of the upper end of each swing plate 6.

[0027] Between the two horizontal plates 2, there is a rotating shaft 11 that can rotate in both directions along the front and rear axis. The rotating shaft 11 has two opposite threaded grooves with opposite helical directions. Each threaded groove is threadedly connected to a horizontal bar 12 in the left and right direction. Multiple U-shaped frames 13, corresponding one-to-one with the clamping blocks 7 and with their openings facing backward, are fixed on the front horizontal bar 12. The U-shaped frames 13 are located to the left or right of the adjacent horizontal axis 5. Multiple stiff bristles 14 are fixed inside each U-shaped frame 13. The box body 1 is equipped with There is a silicone strip 15 located directly below the horizontal axis 5 and in the left-right direction. The silicone strip 15 can move left and right, and multiple soft bristles 16 are fixed on its front and back sides respectively. When the connecting plate 3 moves downward to its limit, every two adjacent swing plates 6 start to drive the surgical forceps 37 to swing back and forth relative to each other or in opposite directions. The angle at the joint of the surgical forceps 37 axis repeatedly increases and decreases. At the same time, the U-shaped frame 13 starts to move back and forth, and the silicone strip 15 starts to move left and right, so as to achieve brushing of the joint of the surgical forceps 37 axis and the teeth.

[0028] In order to enable the connecting plate 3 to drive the two horizontal plates 2 to move up and down, the box body 1 is rotatably connected with a vertical shaft 17 with an up and down axis. The vertical shaft 17 can rotate in both directions. The upper end of the vertical shaft 17 is threadedly connected to the connecting plate 3. The lower end of the horizontal plate 2 is fixed with two left and right opposite lugs 18. The lower end of the lugs 18 is connected to the bottom of the box body 1 via a compression spring 19.

[0029] In order to enable the vertical shaft 17 to rotate in both directions, a slot is provided at the bottom of the housing 1. A motor 20 that can rotate in both directions is fixed in the slot. An intermittent gear 21 is fixed at the output end of the motor 20. The intermittent gear 21 has two teeth and an arc-shaped rack 22 is fixed at its upper end. The lower end of the vertical shaft 17 extends into the slot and is fixed with a first gear 23 that meshes with the arc-shaped rack 22.

[0030] To enable each pair of adjacent swing plates 6 to swing relative to or away from each other, each swing plate 6 has a first toothed groove 24 distributed radially along the horizontal axis 5 on its lower side. The support plate 4 has a base plate 25 fixed at its front end, located below the swing plate 6. The base plate 25 has two left-right opposing guide grooves. A guide block 26 is slidably connected in the guide groove. The upper end of the guide block 26 extends out of the guide groove and is fixed with a movable rack 27 that meshes with the first toothed groove 24. The front end of the movable rack 27 on the left side of each horizontal axis 5 is fixedly connected to the front crossbar 12, and the rear end of the movable rack 27 on the right side of each horizontal axis 5 is fixedly connected to the rear crossbar 12.

[0031] In order to enable the rotating shaft 11 to rotate in both directions, a box 28 with its opening facing upward is fixed to the front side wall of the box 1. A drive rack 29 that can move left and right is slidably connected inside the box 28. A second gear 30 that can mesh with the drive rack 29 is fixed on the rotating shaft 11.

[0032] In order to enable the drive rack 29 to move left and right, the left end of the drive rack 29 is connected to the left side wall of the box 28 via the second spring 31. The front side of the drive rack 29 is provided with a plurality of second tooth grooves 32 distributed in the left and right direction. A support shaft is rotatably connected inside the box 1. The lower end of the support shaft is fixed with a power gear 33 that meshes with the intermittent gear 21, and the upper end of the support shaft passes through the box 28 and is fixed with a transmission gear 34 that meshes with the second tooth grooves 32.

[0033] In order to enable the silicone strip 15 to move left and right, the front end of the silicone strip 15 is fixedly connected to the upper side of the drive rack 29 via the fixing plate 35. The silicone strip 15 has a vertically penetrating relief groove, and the vertical shaft 17 passes through the relief groove.

[0034] In order to better position the surgical forceps 37 and to better clean the joint of the surgical forceps 37 and the first tooth groove 24, the diameter of the positioning post 10 is slightly smaller than the inner diameter of the handle finger ring on the surgical forceps 37, and the horizontal axis 5 is coaxial with the joint of the surgical forceps 37.

[0035] In order to enhance the cleaning and disinfection effect of the surgical forceps 37, the total number of teeth of the arc-shaped rack 22 is a multiple of the total number of teeth of the first gear 23. When the arc-shaped rack 22 and the first gear 23 just disengage, the connecting plate 3 and the vertical shaft 17 disengage from the threaded connection, and the intermittent gear 21 begins to mesh with the power gear 33.

[0036] To prevent the stiff bristles 14 from getting stuck at the joint of the surgical forceps 37, the diameter of the stiff bristles 14 is larger than the axial gap between the two handles at the joint of the surgical forceps 37.

[0037] To facilitate the discharge of disinfectant liquid from the chamber 1, a drain pipe is connected to the bottom of the chamber 1, and a switch valve is installed on the drain pipe.

[0038] To prevent excessive friction between the surgical forceps 37 and the clamping block 7 and to extend the service life of the surgical forceps 37, a soft pad 36 is provided on the inner side of the clamping block 7.

[0039] In use, the first spring 8, the second spring 31, and the compression spring 19 are all uncompressed. The horizontal plate 2 is located above the box 1, with each pair of adjacent swing plates 6 initially swinging at a certain angle. When the surgical forceps 37 needs to be cleaned and disinfected, the prepared disinfectant solution is poured into the box 1, with the solution level higher than the upper surface of the silicone strip 15. After the operator opens the surgical forceps 37 to a certain angle, the finger rings of the surgical forceps 37 are placed on the corresponding positioning posts 10, and the handle is positioned at the opening of the clamping block 7. The surgical forceps 37 is then pushed inward. 7. The surgical forceps 37 presses against the spherical surface of the retaining post 9, causing the retaining post 9 to slide into the sliding hole and compress the first spring 8. When two adjacent retaining posts 9 have slid into the corresponding sliding holes, the handle of the surgical forceps 37 enters the opening of the clamping block 7. Under the action of the first spring 8, the retaining post 9 returns to its original position and prevents the surgical forceps 37 from accidentally moving out of the clamping block 7, thus fixing the surgical forceps 37. At this time, the shaft joint of the surgical forceps 37 is coaxial with the transverse axis 5. Following the above operation, multiple surgical forceps 37 are installed one by one on the corresponding swing plate 6 (refer to the attached diagram of the instruction manual). Figure 1 );

[0040] When the motor 20 is started, it rotates in the forward direction and drives the intermittent gear 21 and the arc rack 22 to rotate. At this time, the power gear 33 does not mesh with the intermittent gear 21, and the arc rack 22 meshes with the first gear 23, causing the vertical shaft 17 to rotate. Since the connecting plate 3 is threadedly connected to the vertical shaft 17 and the horizontal plate 2 is slidably connected to the housing 1, the connecting plate 3 drives the horizontal plate 2, the swing plate 6, the surgical forceps 37 and the U-shaped frame 13 to move downward and compress the compression spring 19. When the arc rack 22 disengages from the first gear 23, the connecting plate 3 and the vertical shaft 17 disengage from the threaded connection. Since the vertical shaft 17 no longer rotates, and under the support of the compression spring 19, the connecting plate 3, the horizontal plate 2, the swing plate 6 and the surgical forceps 37 remain at the current height, and the silicone strip 15 is located at the opening of the surgical forceps 37.

[0041] Simultaneously, the intermittent gear 21 begins to mesh with the power gear 33. The power gear 33, via the support shaft, drives the transmission gear 34 to mesh with the drive rack 29, causing the drive rack 29 to move to the left and compress the second spring 31. At the same time, the second tooth groove 32 on the upper side of the drive rack 29 meshes with the second gear 30, causing the rotating shaft 11 to rotate. Since the crossbar 12 is fixed to the moving rack 27 and threadedly connected to the threaded groove, and the two threaded grooves have opposite directions of rotation, the two crossbars 12 drive the two opposing moving racks 27 to move relative to each other along the rotating shaft 11. The moving rack 27 meshes with the first tooth groove 24, causing the two adjacent swing plates 6 to move the surgical forceps 37. The relative oscillation, that is, the angle at the joint of the surgical forceps 37 shaft decreases; when the intermittent gear 21 disengages from the power gear 33, the drive rack 29 moves to the right under the action of the second spring 31, causing the transmission gear 34 to drive the power gear 33 to rotate in the opposite direction via the support shaft, and the drive rack 29 to drive the second gear 30 to rotate in the opposite direction, causing the two crossbars 12 to move in opposite directions, and each pair of adjacent swing plates 6 to oscillate in opposite directions, thereby increasing the angle at the joint of the surgical forceps 37 shaft. As the motor 20 continues to rotate in the forward direction, the intermittent gear 21 engages with the power gear 33 multiple times, causing the swing plate 6 to drive the angle at the joint of the surgical forceps 37 shaft to repeatedly increase and decrease;

[0042] As the clamping opening of the surgical forceps 37 repeatedly increases and decreases, the front crossbar 12 drives the U-shaped frame 13 to move back and forth repeatedly, stirring the disinfectant in the box 1. This causes the stirred disinfectant to impact the joint and teeth of the surgical forceps 37, and the hard bristles 14 to brush the joint of the surgical forceps 37, removing bloodstains and other dirt remaining on the joint. At the same time, the silicone strip 15 drives the soft bristles 16 to brush the teeth, thoroughly and repeatedly brushing the joint and teeth of the surgical forceps 37.

[0043] After the motor 20 rotates forward for a certain period of time, it begins to rotate in reverse. The intermittent gear 21 and the power gear 33 no longer mesh, the crossbar 12 no longer moves, the silicone strip 15 and the U-shaped frame 13 no longer move, and the hard bristles 14 and soft bristles 16 no longer brush the surgical forceps 37. At the same time, the arc-shaped rack 22 drives the first gear 23 to rotate in reverse, and the first gear 23 drives the vertical shaft 17 to rotate in reverse. Since the connecting plate 3 has a tendency to move upward under the action of the compression spring 19, the connecting plate 3 and the vertical shaft 17 will be re-threaded when the vertical shaft 17 rotates in reverse. The connecting plate 3 drives the cross plate 2, the swing plate 6 and the surgical forceps 37 to move upward and return to the initial state. The motor 20 is turned off. The operator removes the surgical forceps 37 and rinses multiple surgical forceps 37 before placing them in an ultrasonic cleaner to remove tiny residues using the cavitation effect.

[0044] In this invention, the circuit connection relationship of the motor 20 and the time interval between forward and reverse rotation are adjusted using existing control circuits, which will not be described in detail here.
