Technical Field
[0001] This application relates to the field of medical device sterilization equipment technology, and in particular to a surgical instrument sterilization support frame. Background Technology
[0002] Surgical instrument sterilization is a crucial step in hospital infection control and ensuring the safety of clinical surgeries. Pressure steam sterilization is the mainstream sterilization method for reusable surgical instruments in hospitals. The sterilization furnace has a standardized, sealed cavity, and the matching sterilization racks are standard components from the manufacturer, with their length, width, and wheelbase strictly matched to the cavity. Existing sterilization racks are typically multi-layered, with dividers on the shelves for placing sterilization packs and instrument boxes. Surgical instruments are categorized and placed in their respective dividers, then pushed into the sterilization furnace along with the rack for sterilization. After sterilization, they are removed from the rack and transported to the instrument packaging area.
[0003] However, existing sterilization racks typically have a fixed number of shelves and fixed compartment positions, with no adjustable width or shape, making it difficult to accommodate sterilization packs and instrument cases of different sizes. Large items cannot be placed, while small items waste space, resulting in low lateral space utilization. Furthermore, the fixed compartments force instruments to be placed horizontally, preventing them from being sorted by length or thickness and placed at an angle, thus reducing the capacity for sterilization per cycle and failing to meet the sterilization needs of surgical instruments with diverse categories and sizes.
[0004] Therefore, it is necessary to propose a surgical instrument sterilization support frame to solve the above problems. Utility Model Content
[0005] This application provides a surgical instrument sterilization support rack to address the technical problems in existing sterilization racks where the number of shelves and the position of the partition slots are mostly fixed, the slot width and shape are not adjustable, and it is difficult to adapt to sterilization packs and instrument boxes of different sizes.
[0006] This application provides a surgical instrument sterilization support rack, comprising multiple layers of spaced-apart placement plates, with adjacent placement plates fixedly connected by vertically fixed columns. The bottommost placement plate is equipped with a wheel assembly. A limiting frame is fixedly arranged around the top surface of each placement plate, and the inner cavity of the limiting frame is divided into at least two instrument placement areas by limiting steps. Each instrument placement area is provided with multiple flip-up partitions, which are rotatably mounted on right-angle frames. The right-angle frames are slidably mounted on the limiting steps and can be laterally moved to adjust the instrument placement spacing between adjacent flip-up partitions. An angle locking assembly is provided between the flip-up partitions and the right-angle frames to lock and fix the flip-up partitions flipped to a target angle. Both the placement plates and the limiting frames are hollow structures to allow sterilizing steam to penetrate the instrument surface.
[0007] The technical solution described above in this application embodiment has at least the following technical effects: A multi-layered load-bearing structure capable of overall transport is formed by combining multiple layers of spaced placement plates, columns, and wheel sets; the top surface of the placement plate is divided into multiple instrument placement areas by limiting frames and limiting steps, and a rotatable flip-over partition is provided in each instrument placement area. The flip-over partition is slidably mounted on the limiting step via a right-angle frame and can be moved laterally, thereby allowing flexible adjustment of the instrument placement spacing according to instrument specifications. Large instruments can be placed, and small instruments do not waste slot space, improving the utilization rate of lateral space; the flip-over partition is locked at the target flip angle by an angle locking component, facilitating the classification and placement of instruments of different lengths and thicknesses by methods such as oblique placement and separation; the hollow structure of the placement plate and limiting frame allows sterilization steam to penetrate the instrument surface, which is beneficial to improving the uniformity of sterilization. This solves the problems of fixed slots, difficulty in adapting to different specifications of surgical instruments, and low space utilization in existing sterilization racks.
[0008] In some embodiments, a placement mechanism is provided on the top surface of the placement plate. The placement mechanism includes an adapter component and an adjustment component. The adapter component includes a flip partition, a limiting frame, a limiting step, and a right-angle frame. The limiting frame is fixedly connected to the outer ring of the top surface of the placement plate. The limiting step is symmetrically fixed to the inner side wall of the limiting frame. The right-angle frame is slidably assembled to the inner side of the limiting step. The flip partition is rotatably assembled to the side end face of the right-angle frame.
[0009] In some embodiments, a T-shaped slider is fixedly connected to the bottom surface of the right-angle frame, and a T-shaped groove is provided on the bottom edge of the inner side wall of the limiting step. The T-shaped slider is slidably embedded in the T-shaped groove so that the right-angle frame drives the flip partition to move laterally along the limiting step to adjust the installation position.
[0010] In some embodiments, the adapter component further includes a limiting toothed disc, a biting tooth, a damping spring assembly, and a slot; the limiting toothed disc is fastened to the side of the flip partition and rotates synchronously with the flip partition; the end cavity of the right-angle frame has a slot; the biting tooth slides vertically through the slot and its top teeth mesh with the outer ring teeth of the limiting toothed disc; the damping spring assembly is fastened between the bottom end of the biting tooth and the bottom surface of the slot cavity, and is used to continuously push the biting tooth so that the biting tooth and the limiting toothed disc remain engaged and locked.
[0011] In some embodiments, the adjusting assembly includes a pull rod, a hinge bracket, a spring, support rods, pins, a cavity, and a partition. The inside of the flip partition is hollow, forming a cavity. The partition is vertically fixed in the middle of the cavity and divides the cavity into two independent chambers. The pull rod slides laterally through the center of the partition. One end of the pull rod extends outward through a long strip opening on the bottom surface of the flip partition. The other end of the pull rod is fixedly connected to the hinge bracket. The spring is sleeved on the outside of the pull rod, and its two ends abut against the partition and the hinge bracket, respectively. Two support rods are hinged to the hinge bracket and arranged outward in a figure-eight shape. The outer ends of the two support rods are respectively hinged to pins. The pins extend outward through the front and rear side walls of the flip partition.
[0012] In some embodiments, the outer cylindrical surface of the outwardly extending end of the pin has multiple evenly distributed limiting grooves, and the center of the front and rear end plates of the right-angle frame has holes. The inner ring of the holes has multiple limiting protrusions integrally formed, and the limiting protrusions are matched and engaged with the limiting grooves. The inner wall of the holes slides in cooperation with the outer cylindrical surface of the pin. Each pair of oppositely arranged limiting steps has multiple sets of pin holes equidistantly opened on the facing sidewalls. The exposed end of the pin can be inserted into the pin holes at different positions to lock the lateral position of the flip partition.
[0013] In some embodiments, the placement plate has three layers and the components of the three placement plates are completely identical. Four columns are vertically fixed at the four corners of the top surface of the bottom placement plate, and the columns pass through and fix the two upper placement plates in sequence. Four sets of wheels are respectively assembled at the four corners of the bottom surface of the bottom placement plate to support and drive the overall transport and movement of the support frame.
[0014] The beneficial effects of this utility model are as follows: A multi-layered load-bearing structure capable of overall transport is formed by combining multiple layers of spaced placement plates, columns, and wheel assemblies; the top surface of the placement plates is divided into multiple instrument placement areas by limiting frames and limiting steps, and a rotatable flip-over partition is provided in each instrument placement area. The flip-over partition is slidably mounted on the limiting step via a right-angle frame and can move laterally, thus allowing for flexible adjustment of instrument placement spacing according to instrument specifications. Large instruments can be placed comfortably, while small instruments do not waste slot space, improving the utilization rate of lateral space; the angle locking component locks the flip-over partition at the target flip angle, facilitating the classification and placement of instruments of different lengths and thicknesses by methods such as oblique placement and separation; the hollow structure of the placement plates and limiting frames allows sterilization steam to penetrate the instrument surface, improving the uniformity of sterilization. This solves the problems of fixed slots, difficulty in adapting to different sizes of surgical instruments, and low space utilization in existing sterilization racks. Attached Figure Description

[0017] Based on this, in order to improve the technical problems existing in related technologies, such as the fixed number of shelves and the fixed position of the partition slots in the existing sterilization racks, the inability to adjust the slot width and slot shape, and the difficulty in adapting to sterilization packs and instrument boxes of different sizes, the embodiments of this application provide the following solutions.
[0018] Please refer to the following: Figures 1 to 10This utility model proposes a surgical instrument sterilization support rack, comprising multiple layers of spaced-apart placement plates 111. Adjacent placement plates 111 are fixedly connected by vertically fixed columns 112. The bottom layer of placement plate 111 is equipped with a wheel assembly 113. A limiting frame 212 is fixedly mounted around the top surface of each placement plate 111. The inner cavity of the limiting frame 212 is divided into at least two instrument placement areas by limiting steps 213. Each instrument placement area is provided with multiple flip-up partitions 211. The flip-up partitions 211 are rotatably mounted on right-angle frames 214, and the right-angle frames 214 are slidably mounted on the limiting steps 213 and can be moved laterally. An angle locking assembly is provided between the flip-up partitions 211 and the right-angle frames 214. Both the placement plates 111 and the limiting frames 212 are hollow structures.
[0019] The placement plate 111 has three layers, and the components of the three placement plates 111 are completely identical, facilitating modular assembly and interchangeability. Four uprights 112 are provided, each vertically fixed to one of the four corners of the top surface of the bottom placement plate 111. The uprights 112 extend upwards, successively penetrating and securing the two upper placement plates 111. Four sets of wheels 113 are provided, each mounted at one of the four corners of the bottom surface of the bottom placement plate 111. This arrangement allows the uprights 112 to provide vertical support for the upper placement plates 111 and to position the horizontal relative positions of each layer. The wheels 113 support and drive the entire support frame for transport and movement, facilitating the operator to push the support frame to the designated workstation on the sterilization equipment and also facilitating the removal and transport of the support frame after sterilization.
[0020] In this embodiment, a placement mechanism 2 is provided on the top surface of the placement plate 111. The placement mechanism 2 includes an adapter component 21 and an adjustment component 22. The adapter component 21 includes a flip partition 211, a limiting frame 212, a limiting step 213, and a right-angle frame 214, used to support the instrument and adjust its placement posture. The adjustment component 22 includes a pull rod 228, a hinge bracket 2211, a spring 2212, a support rod 2213, and a pin 223, used to adjust the lateral position of the flip partition 211. The limiting frame 212 is fixedly attached to the outer ring of the top surface of the placement plate 111. The limiting step 213 is symmetrically fixed to the inner side wall of the limiting frame 212. The right-angle frame 214 is slidably assembled on the inner side of the limiting step 213. The flip partition 211 is rotatably assembled on the side end face of the right-angle frame 214. Thus, the adapter component 21 and the adjustment component 22 cooperate to realize the position adjustment of the flip partition 211 in both the lateral and flip directions.
[0021] For example, four sets of limiting steps 213 are provided, which are symmetrically arranged front and back within the limiting frame 212, dividing the inner cavity of the limiting frame 212 into two sets of instrument placement areas with completely identical dimensions. The two placement areas can respectively support different types of instruments. The limiting steps 213 serve as the boundary of the instrument placement area and also provide limiting and abutting surfaces for the bottom front and back sides of the flip partition 211. When all flip partitions 211 are kept in a horizontal and flat state, the top surfaces of each flip partition 211 are flush with each other, so that the overall top surface of the placement plate 111 forms a flat bearing plane, which is convenient for placing large sterilization packs and instrument boxes and can avoid instrument slippage caused by uneven support surfaces.
[0022] A T-shaped slider 2214 is fixedly connected to the bottom surface of the right-angle frame 214. A T-shaped groove 222 is provided on the bottom edge of the inner sidewall of the limiting step 213. The T-shaped slider 2214 is slidably fitted into the T-shaped groove 222, allowing the right-angle frame 214 to drive the flip partition 211 to move laterally along the limiting step 213 to adjust the installation position. The two end faces of the right-angle frame 214 respectively abut against the inner sidewall of the corresponding limiting step 213, and the bottom front and rear sides of the flip partition 211 abut against the inner sidewall of the limiting step 213. As a preferred embodiment, the fitting structure of the T-shaped slider 2214 and the T-shaped groove 222 allows the right-angle frame 214 to move in one direction while restricting its movement in other directions, thereby ensuring a smooth and stable spacing adjustment process.
[0023] The adapter component 21 also includes a limiting gear 215, a meshing tooth 216, a damping spring assembly 217, and a slot 218. The limiting gear 215 is securely mounted on the side of the flip partition 211 and rotates synchronously with the flip partition 211. The end cavity of the right-angle frame 214 has a slot 218, and the meshing tooth 216 slides vertically through the slot 218. The teeth at the top of the meshing tooth 216 mesh with the teeth on the outer ring of the limiting gear 215. The damping spring assembly 217 is securely connected between the bottom end of the meshing tooth 216 and the bottom surface of the inner cavity of the slot 218, and is used to continuously push the meshing tooth 216 to keep the meshing tooth 216 engaged and locked with the limiting gear 215.
[0024] Furthermore, the limiting gear disc 215 can be fixedly installed at the front and rear ends of the left side of the flip partition 211. Correspondingly, the inner cavities at the front and rear ends of the right-angle frame 214 are respectively provided with slots 218, and the two sets of slots 218 are respectively vertically slidingly inserted with meshing teeth 216. The two sets of damping spring groups 217 push the corresponding meshing teeth 216. During the flipping process of the flip partition 211, the limiting gear disc 215 rotates synchronously with the flip partition 211, and the outer ring teeth squeeze the meshing teeth 216 step by step to compress the damping spring groups 217 downward. When the flip partition 211 flips to the required angle and stops lifting, the damping spring groups 217 rebound and push the meshing teeth 216 upward to re-mesh with the limiting gear disc 215. The elastic damping force of the damping spring groups 217 offsets the weight of the flip partition 211 and the instrument it carries, realizing the stepless damping self-locking of the flip partition 211 at any target angle. With this configuration, the flip-up partition 211 can stop and lock at any angle between horizontal and vertical, making it easy for operators to select the angle of placement according to the length and quantity of instruments, thereby increasing the instrument capacity per unit area without increasing the number of slots.
[0025] The adjusting assembly 22 includes a pull rod 228, a hinge bracket 2211, a spring 2212, a support rod 2213, a pin 223, a cavity 229, and a partition 220. The interior of the flip partition 211 is hollow, forming a cavity 229. The partition 220 is vertically fixed to the center of the cavity 229, dividing it into two independent chambers. The pull rod 228 slides laterally through the center of the partition 220. One end of the pull rod 228 extends outward through a long strip-shaped opening 227 on the bottom surface of the flip partition 211, and the other end is fixedly connected to the hinge bracket 2211. The spring 2212 is sleeved on the outside of the pull rod 228, with both ends abutting against the partition 220 and the hinge bracket 2211 respectively. Under normal conditions, it applies an elastic force towards the exposed end of the pull rod 228 to the hinge bracket 2211. Two support rods 2213 are hinged to the hinge bracket 2211 and arranged outward in a figure-eight shape. The outer ends of the two support rods 2213 are respectively hinged to pins 223, which extend outward through the front and rear side walls of the flip partition 211.
[0026] For example, one end of the pull rod 228 extending beyond the bottom surface of the flip partition 211 can be integrally connected to the lever structure. When the operator moves the lever to the right, the pull rod 228 drives the hinge bracket 2211 to move to the right simultaneously and compresses the spring 2212. The two support rods 2213 retract inward, driving the two pins 223 to retract towards the center of the flip partition 211. After releasing the lever, the spring 2212 rebounds and pushes the hinge bracket 2211 to the left, and the support rods 2213 expand outward to push the push rod 223 back to its original position. With this configuration, the operator can control the opening and closing of the two support rods 2213 with one hand, synchronously driving the extension and retraction of the two pins 223, realizing single-point control of the spacing adjustment, which facilitates quick spacing adjustment.
[0027] The outer cylindrical surface of the outwardly extending end of the pin 223 has multiple evenly distributed limiting grooves 224. Holes 225 are provided at the center of the front and rear end plates of the right-angle frame 214. The inner wall of the hole 225 slides in contact with the outer cylindrical surface of the pin 223. Multiple limiting protrusions 226 are integrally formed within the inner ring of the hole 225. The limiting protrusions 226 and the limiting grooves 224 on the outer cylindrical surface of the pin 223 are fitted together. This design allows the pin 223 to slide axially while restricting its circumferential rotation, ensuring smooth rotational engagement between the pin 223 and the limiting gear plate 215 and the flipping partition 211, and preventing vibration caused by circumferential movement of the pin 223 during flipping.
[0028] Each pair of opposing limiting steps 213 has multiple sets of pin holes 221 equidistantly spaced on their opposing sidewalls. The exposed ends of the pins 223 can be inserted into the pin holes 221 at different positions to lock the lateral position of the flip partition 211. For example, the hole spacing of the pin holes 221 is the minimum resolution for adjusting the lateral position of the flip partition 211. By selecting different positions of the pin holes 221, multiple lateral positioning positions of the flip partition 211 can be achieved. After positioning, the insertion and engagement of the pins 223 and the pin holes 221 is rigid and reliable, capable of withstanding lateral forces during instrument placement and flipping, and preventing spacing positioning failure.
[0029] The placement plate 111 is a recessed, hollow, one-piece molded structure with a hollowed-out grid or strip-shaped grid pattern on its surface. The limiting frame 212 is a hollowed-out frame structure, and the bottom surface of the flip-up partition 211 has a long strip-shaped opening 227. This design allows sterilizing steam to pass through all bearing surfaces from below and to the sides of the placement plate 111 and act evenly on the instrument surface. It penetrates the instrument surface simultaneously in both vertical and horizontal directions, avoiding the obstruction of steam flow by traditional solid shelf structures, improving sterilization uniformity, and shortening the sterilization time to achieve the required standard.
[0030] During assembly, four uprights 112 are first vertically fixed to the four corners of the top surface of the bottom placement plate 111. Then, the second and third layer placement plates 111 are positioned and fixed sequentially using the uprights 112. After each layer of placement plates 111 is assembled, a limiting frame 212, a limiting step 213, a right-angle frame 214, and a flip partition 211 are installed on each placement plate 111 to form a complete functional unit. Since the component specifications of the three layers of placement plates 111 are completely identical, modular pre-assembly can be performed before overall stacking, reducing assembly difficulty. The interchangeability of the functional units at each layer facilitates subsequent maintenance and replacement.
[0031] In use, the support frame is pushed to the designated station of the sterilization equipment using the bottom wheel assembly 113, and the surgical instruments are laid flat on the horizontally positioned flip-over partition 211. When it is necessary to separate or diagonally place surgical instruments of different sizes, the lever 228 exposed on the bottom surface of the flip-over partition 211 is moved to the right, causing the lever 228 to move to the right and compress the spring 2212. The lever 228 pulls the hinged bracket 2211 to move to the right simultaneously, and the two support rods 2213 arranged in a figure-eight shape move inward simultaneously, causing the two pins 223 to retract towards the center of the flip-over partition 211, so that the ends of the pins 223 disengage from the pin holes 221. At this time, relying on the sliding cooperation between the T-shaped slider 2214 and the T-shaped groove 222, the right-angle frame 214 and the flip-over partition 211 are moved laterally to adjust the instrument storage spacing between adjacent flip-over partitions 211. After the spacing adjustment is completed, release the pull rod 228. The spring 2212 rebounds, pushing the hinge bracket 2211 to the left. The support rod 2213 expands outward, pushing the push rod 223 back to its original position. The end of the pin 223 inserts into the corresponding pin hole 221 to achieve lateral positioning and locking. Then, lift the flip partition 211 upward. The flip partition 211 rotates around the pin 223 as the axis. The limiting gear 215 rotates synchronously and squeezes the meshing teeth 216 to compress the damping spring assembly 217. After flipping to the desired angle, stop lifting. The damping spring assembly 217 rebounds, pushing the meshing teeth 216 to re-engage with the limiting gear 215, achieving stable self-locking of the flip partition 211. The entire spacing and angle adjustment process requires no tools and can be completed with one hand for unlocking, lateral movement, and locking.
[0032] After sterilization, reverse the levers 228 at the bottom of each flip-up partition 211 to retract and unlock the pins 223. Then, slide each flip-up partition 211 outwards or flip it to an angle suitable for cleaning. Next, disassemble each layer of placement plates 111 and column 112 to thoroughly clean and disinfect the support frame. The hollow, recessed structure exposes the surfaces of all components directly, eliminating any enclosed corners and facilitating the rinsing of dirt, thus meeting the cleanliness requirements for infection control.
[0033] In a preferred embodiment, the main load-bearing components, such as the placement plate 111, the limiting frame 212, the flip partition 211, the right-angle frame 214, and the column 112, can be made of medical-grade stainless steel, and all fasteners and transmission components use standard parts of the same material. Medical-grade stainless steel is resistant to high temperatures and corrosion, meeting the requirements for use under pressure steam sterilization conditions, which helps extend the service life of the support frame and ensures structural stability after repeated sterilization.
[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
