[0001] A management system for surgical instruments in the operating room. Background Art
[0002] Surgeons and their assistants need to have easy access and arrangement of their instruments and other supplies during surgery. Searching for forceps that are obscured or touched by other instruments, for example, can add critical surgical time. This is undesirable for the patient, as delays increase surgical time as well as prolonging anesthesia, which increases the risk of postoperative infection.
[0003] Increasing the time it takes to perform each surgery is detrimental to the surgeon, other physicians and staff, and the hospital or surgical center. Delays for each surgical team compound delays for the other teams, which also delays the next surgical procedure, limiting operating room efficiency and increased patient throughput.
[0004] After each surgery, the team typically hangs all instruments used during surgery or brought into the operating room on skewers (two parallel, spaced stainless steel rods) through the instruments’ finger holes. These rods (skewers) organize and secure instruments for easy transport and organization, but do not allow for identification and quick access to individual instruments. Instruments are sprayed with disinfectant to kill microorganisms that may have freely drifted into hospital hallways during transportation back to the sterile processing department, and to prevent airborne transmission within the sterilization department. Loading instruments on the rods, removing them for sterilization, and then rearranging them for the next surgery are time-consuming and inefficient activities that increase the risk of gloves being damaged or instruments falling to the ground and needing to be replaced.
[0005] Increased costs and decreased efficiency aren’t the only concerns. Each team must count all instruments at the beginning and end of a procedure. For example, if the team starts with ten of a certain instrument and uses seven, leaving three unused, the seven used and the three unused must be recorded. If any instruments are missing, the team must determine how many are missing. Once identified, finding the missing instrument or instruments can be difficult and time-consuming, which can add to the overall length of the procedure, especially when considering the situation per procedure, per operating room, per hospital, and even the entire healthcare system. Some estimates suggest that the cost of one minute of delay in each operating room is approximately $40.
[0006] The managed instruments must be kept sterile during surgery, and special care must be taken to prevent the instruments from coming into contact with non-sterile areas or objects within the operating room. The management system provided by the present invention facilitates the sterilization of instruments, organizes them together, and reduces unintentional contamination within the operating room. This is more efficient than sterilizing instruments individually and then loading them for each upcoming surgery.
[0007] High temperature steam used for sterilization may have adverse effects on management system components, so it is important to select system components that will not be damaged by heat and substances.
[0008] Different types of surgeries (such as cardiac surgery and orthopedic surgery) often require different types and quantities of instruments. The management system provided by the present invention greatly facilitates the organization, responsibility tracking and continuous management of surgical instruments. Summary of the invention
[0009] The management system for containing surgical instruments of the present invention includes a tray having a base. The tray may have side walls and a cover extending over the base to the side walls. The base has openings that allow steam and ethylene oxide (EO) gas to circulate around the surgical instruments. The side walls and cover may also have similar openings.
[0010] The rear upright instrument supports are attached to the base and each supports a stack of handle ends of surgical instruments. The rear upright instrument supports have a protrusion that conforms to the structure of one end of the surgical instrument. The rear upright instrument supports have at least one foot attached to the base.
[0011] A front support (which is also fixed to the base of the tray) is located in front of the rear upright instrument support and the surgical instruments stacked therein. The front support accommodates the front end portion of the fixed instrument. For many instruments, the front support is close to the hinge of the instrument, but it can be spaced from the hinge, particularly for longer forceps or other instruments. The front support has spaced-apart members that can be U-shaped, each spaced-apart member having segments spaced-apart from each other. A single member can replace two spaced-apart members. The other end of the instrument is placed between the members of the front support. The arm is mounted on the hinge between the segments of the spacing member and extends toward the segment of another spacing member. When the stack of instruments reaches a predetermined number, the arm will contact the topmost instrument and remain horizontal, i.e., parallel to the base of the tray.
[0012] The arm can be pivoted upward to load the instrument and not touch the instrument, so that the top instrument can be added or removed from the stack. Each time the top instrument is removed from the stack, the arm is pivoted back below the horizontal starting position and rests on the new top instrument. When another instrument is removed from the stack, the arm can be pivoted further.
[0013] Numbers can be printed on the front support near the end of the arm. The number "1" is where the end of the arm falls when one instrument is removed from the front support. The number "2" is where the end of the arm is when the second instrument is removed, etc. These numbers can alert the surgical team which instruments are in use and which instruments may be lost deep within the body cavity or under a drape, floor, etc. The safety warning bar is limited from being lowered too far beyond the reach of fingers by a horizontal metal bar between the two side walls.
[0014] The type of device may be printed on the substrate or support. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The management system 10 includes a tray 12 having a base 14 ( Figure 2 , 3 ). The tray has a series of openings 16, Figure 2 and Figure 3 In the embodiment shown the openings are circular and aligned, but the openings can be other shapes and can be arranged differently.
[0025] The sidewalls 20 extend perpendicularly from the four sidewall edges of the base 14. The corners 22 of the sidewalls may be curved to avoid sharp corner edges. The sidewalls also have a series of openings 28, which may be different in size or shape from the openings 16 in the base. The cover 24 ( Figure 1 ) may be attached to the top 26 of the side wall. The lid also has a series of openings 30.
[0026] The base 14 or other component may have printed indicia showing the device at each position.
[0027] The lid 24 may be secured to the tray 12. Figure 1 , 9 and 10. The slider 32 can move horizontally in the opening 42. The slider can have a finger grip protrusion 36 and an engagement protrusion 34. Pull the slider to the right ( Fig. 9 and Fig.10 ) will move the engagement protrusion in the groove 40. Pushing the slider to the left will move the engagement protrusion out of the groove to release the cover 24.
[0028] The dimensions of the tray can vary. In one system, the tray 12 can be 51.5 mm wide and 32.5 mm deep. The height of the sidewalls 20 can be 4.8 mm. When the lid 24 is attached to the tray, the overall dimensions of the entire tray become 52.5 mm wide, 33.5 mm deep, and 5 mm high. The tray can fit into a wide body In sterile container, see www.aesculapusa.com( Accessed March 29, 2023). Steam and ethylene oxide (EO) can reach the instruments within the tray through openings 16, 28, 30 to sterilize them. The base, side walls and lid may be aluminum, but other non-corrosive materials that are not adversely affected by heat and chemicals during the sterilization process may also be used. Depending on the height of the tray and its side walls, two trays can be stacked on top of each other within the Aesculap container. Other manufacturers may choose to expand the width of their sterilization containers to accommodate the management system of the present invention. If wider components are not in stock, standard hospital procedures allow for wrapping any items in CSR packaging, thereby sterilizing the contents of the packaging and sending it to the operating room. Depending on the instruments loaded on the tray, the weight of a fully loaded tray is approximately 2 kg (≈6 lbs)
[0029] A rear upright instrument support 50 is attached to the base 14 for receiving instruments in the tray 12. Figure 2 , 3 and 8. See also rear upright instrument support 80 ( Figure 6 ) and rear upright apparatus support 100 ( Figure 7 ). The support 50 may be stamped stainless steel or another non-corrosive material. The rear upright instrument support may be attached to the base using automated laser welding or other fastening techniques. An opening (not shown) may be provided in the base into which the rear upright instrument support extends for fastening.
[0030] The rear upright instrument supports can have different configurations depending on the instruments they store. Figure 2 and Figure 3The number of mid- and rear-standing machine supports and the distances between them may be referenced by numbers on the components of the different supports. Figure 8 A rear upright instrument support is shown having elements spaced sufficiently far apart.
[0031] Rear upright apparatus support 50 ( Figure 2 and Figure 3 , Figure 3 The apparatus is also shown having first and second spaced-apart upright members 52 and 54, with at least one gap between the upright members 52 and 54. Figure 1 and Figure 2 The rear upright instrument support in FIG. 1 has two gaps 56 and 58 with a center plate 60 between the gaps. The bottoms of the legs 62 and 64 contact the surface of the base 14. The bottoms can be automatically laser welded to the base 14, but other fastening methods can also be used with the system. This figure does not show the structure of the bottom of the legs for attaching the legs to the base 14.
[0032] exist Figure 2 In the embodiment shown, each rear upright instrument support has a rearwardly facing panel 68 and 70, each panel having a recess 72, 74.
[0033] Figure 8 The rear upright instrument support 50 depicted is shown to accommodate the handle end of an instrument such as forceps 150. The structure around the finger holes 152 and 154 of the bottom forceps is located at the bottom of the grooves 72 and 74, and the handles 156 and 158 are located at the bottom of the gaps 56 and 58. The forceps 160 are located above the forceps 150, and the depth of the gaps and grooves allows for the addition of instruments. This structure firmly holds the instrument in place, allowing it to protrude forward from the support without moving too much from side to side.
[0034] The rear upright instrument support can also arrange the contained instruments through the jaws of forceps or the blades of scissors to sterilize the jaws or blades.
[0035] Figure 6 A different rear upright instrument support (80) is shown for securing the handle end of an instrument such as forceps 170. Spaced apart upright members 82 and 84 extend to curved portions 86 and 88. The structure around finger holes 172 and 174 may conform to the curved portions. The curved portions may have offset ends to aid in placing the finger openings of an instrument on the curved portions.
[0036] The legs 92 and 94 of the rear upright machine support 80 are shorter than the legs of the support 50 ( Figure 8 ). Support 80 can accommodate more instruments, so the shorter legs position the uppermost instrument at approximately the same height on both supports.
[0037] Upright members 82 and 84 are not as Figure 8 The center plate is the same as the plate 60 in FIG. Figure 6 The gap 66 in is uninterrupted and wider.
[0038] Figure 7 A third rear upright instrument support 100 is shown. It can be formed from a bent sheet of stainless steel. It has a front upright wall 102 with two cutouts 104 and 106 and two upright extensions 108 and 110 extending from a base 112. A rear wall 114 extends upward from the base and bends backward at 116 and then extends upward to 118 to form a shelf for the rear end of the forceps. A partition 120 separates the rear ends of the forceps. The inner sides of the partition and upright extensions 108 and 110 secure the rear ends of the forceps. A crosspiece 122 is a support surface for the bottommost instrument.
[0039] When the management system is configured with a specific number of instruments, the rear upright instrument supports can be selected to have a corresponding distance from the instrument support surface above the base 14. From that height, the distance of the uppermost instrument can be determined. If all uppermost instruments are the same distance above the base, the system can use rear upright instrument supports with the correct distance from the base to the surface supporting the lowermost instrument.
[0040] Front support member 130( Figure 2-5 ) is mounted in front of each rear upright instrument support. For many forceps or scissors, the position of the front support is at or near the position of the shear axis when the instrument is in the rear upright instrument support.
[0041] Figure 4 and Figure 5 The front support 130 in the embodiment has first and second spaced apart members 132 and 134. Two spaced apart members increase the rigidity of the front support, but a single member is also acceptable. The upright member 132 has first and second sides 136 and 138, and a platform 140 located between the sides. The platform is the surface on which the underlying surgical instruments are placed.
[0042] When the second member 134 is used, its shape is similar to the first member 132. Both members are welded to the substrate 14.
[0043] A scale 142 extends upwardly from the second side of the first member. A pin or hinge 144 is mounted through the first side of the platform, and the proximal end of a rod (146) is mounted on the hinge for rotation. The distal end of the rod extends adjacent to the scale. The scale is designed so that the rod 146 will be horizontal and aligned with the "4" on the scale when the system accommodates four instruments. If the four instruments are removed, the rod will drop below the "1" and contact the stop 148.
[0044] The rod 146 can be pivoted out of the vertical position (see Figure 5 ) to remove the instruments or return them to the front support 130. During surgery, the rod should not be kept Figure 5 If the instrument is removed, the rod should be positioned along Figure 5 Rotate counterclockwise back. If the instrument is reloaded after surgery, the rod can remain Figure 5 position until the front support is fully loaded. If the bar is above the horizontal position after full loading, this means that the support is overloaded.
[0045] The above description is for illustration, not for limitation, and is only for example. Although the application shows and describes examples, those with ordinary skills will find that they can make modifications, changes or variations. Many examples involve specific combined method steps or system elements, but these steps and elements can be combined in other ways to achieve the same purpose. The behavior, elements and features discussed only in one embodiment do not mean that similar effects cannot be played in other embodiments.
[0046] "Plurality" means two or more. A "group" of items may include one or more such items. "Include," "comprising," "carrying," "having," "containing," "involving," and similar words in the specification or claims are open-ended, that is, each means "including but not limited to." Only the transition phrases "consisting of..." and "consisting mainly of..." are closed or semi-closed transition phrases, especially with respect to the claims. Ordinal numbers such as "first," "second," and "third" in the claims do not by themselves indicate the priority, precedence, or temporal order of performance of method actions of one claim element relative to another. Instead, they are merely labels used to distinguish one claim element with a certain name from another element with the same name (but without the use of an ordinal number). Alternatives such as "or" include any combination of one or listed items.
