[0022] The present application also provides a medical device box, including:

[0023] The box body includes a receiving cavity, and the top of the box body is provided with an opening communicating with the receiving cavity;

[0024] a box cover movable relative to the box body between an open position and a closed position, wherein the box cover opens the opening when in the open position and closes the opening when in the closed position;

[0025] A mounting post is installed in the accommodating cavity, the mounting post extends along the height direction of the box body, and the upper end of the mounting post is used to be inserted into the through hole of the gasket so that the gasket is sleeved on the mounting post;

[0026] In which, the mounting column can move relative to the box body along the height direction, and the medical device box also includes an elastic member installed in the accommodating cavity, which is connected to the mounting column and is used to drive the mounting column to move upward.

When the case lid is in the closed position, a portion of the mounting posts is positioned within the receiving hole, and the minimum spacing W between the outer circumference of the mounting posts and the inner circumference of the receiving hole is less than the minimum width K between the inner and outer rings of the gasket. Consequently, when the case lid is in the closed position, the gasket cannot pass through the gap between the outer circumference of the mounting posts and the inner circumference of the receiving hole. The edge of the receiving hole in the case lid abuts against the gasket, securing the gasket against the mounting posts and preventing it from falling off the mounting posts. Furthermore, even if the case lid moves upward a certain distance relative to the mounting base in the closed position due to assembly precision errors or deformation, the edge of the receiving hole in the case lid still abuts against the gasket, securing the gasket in place. This solves the problem of gaskets falling off the mounting posts in existing medical device cases when the case lid is not opened due to assembly precision errors or deformation of the case lid.

[0051] The present invention provides a medical instrument case, which is described in detail below.

[0052] Figure 1 This is a structural diagram of an embodiment of the medical equipment box provided in an embodiment of the present application. Figure 2 for Figure 1 Enlarged view of point A in the middle. Figure 3 A schematic structural diagram of an embodiment of a box cover provided in an embodiment of the present application. Figure 4 This is a structural diagram of an embodiment of the box, mounting plate and mounting column provided in the embodiment of the present application. Figures 1 to 4As shown, the medical device case 100 includes a case body 110 and a case cover 120. The case body 110 includes a receiving cavity 1100. The top of the case body 110 is provided with an opening 1101 communicating with the receiving cavity 1100. The case cover 120 is movable relative to the case body 110 between an open position and a closed position. When the case cover 120 is in the open position, the opening 1101 is opened, and when the case cover 120 is in the closed position, the opening 1101 is closed.

[0053] When the box cover 120 is in the open position, medical devices can be placed into the accommodating cavity 1100 through the opening 1101 of the box body 110, or medical devices in the accommodating cavity 1100 can be taken out through the opening 1101. When the box cover 120 is in the closed position, the box cover 120 can close the opening 1101 of the box body 110 to protect the medical devices in the accommodating cavity 1100 and prevent the medical devices in the accommodating cavity 1100 from falling out.

[0054] The box cover 120 can be movably connected to the box body 110, so that the box cover 120 can move between an open position and a closed position relative to the box body 110. Alternatively, the box cover 120 can be detachably connected to the box body 110. When the box cover 120 is detachably mounted on the box body 110, the box cover 120 is in the closed position. When the box cover 120 is removed from the box body 110, the box cover 120 moves from the closed position to the open position relative to the box body 110.

[0055] Continue to refer to Figures 1 to 4 The medical device box 100 may include a mounting column 130, which is installed in the accommodating cavity 1100 and extends along the height direction X of the box body 110. The upper end of the mounting column 130 is used to be inserted into the through hole of the gasket 200 so that the gasket 200 is sleeved on the mounting column 130.

[0056] By installing the washer 200 on the mounting column 130 instead of the screw mounted in the accommodating cavity 1100, the surgeon can directly remove the washer 200 from the mounting column 130 during the operation without having to remove the screw from the accommodating cavity 1100 and then remove the washer 200 from the screw, making it more convenient to take the washer 200 and helping to improve surgical efficiency.

[0057] In some embodiments, the box cover 120 includes an inner surface 1201 and an outer surface 1203 opposite to each other. A receiving hole 1202 may be provided on the inner surface 1201 of the box cover 120. When the box cover 120 is in the closed position, the inner surface 1201 of the box cover 120 faces the receiving cavity 1100, and a portion of the mounting post 130 is located in the receiving hole 1202. Figure 2 As shown, the minimum distance between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202 is W, the minimum width between the inner ring and the outer ring of the washer 200 is K, and W<K.

[0058] The medical device box 100 provided in the embodiment of the present application is configured such that a mounting post 130 is arranged in the accommodating cavity 1100 of the box body 110, and an accommodating hole 1202 is opened on the inner surface 1201 of the box cover 120, so that when the box cover 120 is in the closed position, a portion of the mounting post 130 is located in the accommodating hole 1202, and the minimum spacing W between the outer circumferential surface of the mounting post 130 and the inner circumferential surface of the accommodating hole 1202 is less than the minimum width K between the inner and outer rings of the gasket 200.

[0059] When the box cover 120 is in the closed position, the gasket 200 cannot pass through the gap between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202. The edge of the receiving hole 1202 of the box cover 120 can abut against the gasket 200, thereby confining the gasket 200 to the mounting post 130 and preventing the gasket 200 from falling off the mounting post 130. Moreover, when the box cover 120 moves upward a certain distance relative to the mounting seat when in the closed position due to assembly accuracy errors or deformation of the box cover 120, the edge of the receiving hole 1202 of the box cover 120 can still abut against the gasket 200 to limit the gasket 200. This solves the problem of the gasket 200 falling off the mounting post 130 when the box cover 120 is not opened due to assembly accuracy errors or deformation of the box cover 120 in the existing medical instrument box 100.

[0060] In some embodiments, the receiving hole 1202 defined in the inner surface 1201 of the box cover 120 can extend through the box cover 120, that is, the receiving hole 1202 extends from the inner surface 1201 to the outer surface 1203 of the box cover 120. This maximizes the depth of the receiving hole 1202 in the thickness direction of the box cover 120, allowing the mounting post 130 to be positioned within the receiving hole 1202 for as long as possible. This allows the box cover 120 to have a greater assembly precision error or greater deformation while still effectively retaining the gasket 200 at the mounting post 130.

[0061] Of course, the receiving hole 1202 can also be a blind hole, that is, the receiving hole 1202 extends from the inner surface 1201 of the box cover 120 to the outer surface 1203, and there is a certain distance between the bottom surface of the receiving hole 1202 and the outer surface 1203 of the box cover 120. In this case, when the box cover 120 is in the closed position, the upper end of the mounting post 130 can be inserted into the receiving hole 1202.

[0062] In the embodiment of the present application, when the box cover 120 is in the closed position, the upper end of the mounting post 130 can be positioned within the receiving hole 1202, thereby enabling the box cover 120 to protect the mounting post 130 and reduce the risk of deformation or even damage to the mounting post 130 caused by impact. The receiving hole 1202 can be a through hole that passes through the box cover 120 or a blind hole.

[0063] Of course, when the box cover 120 is in the closed position, the upper end of the mounting post 130 can also protrude from the outer surface 1203. That is, the mounting post 130 passes through the receiving hole 1202 and protrudes from the upper surface of the box cover 120. This can also effectively restrict the gasket 200 to the mounting post 130, and can also allow the box cover 120 to have a larger assembly precision error or greater deformation. The receiving hole 1202 is a through hole that penetrates the box cover 120.

[0064] like Figure 2 As shown, the inscribed circle diameter of the radial cross-section of the receiving hole 1202 is D1, and the circumscribed circle diameter of the radial cross-section of the mounting post 130 is D2. In some embodiments, 1.5 mm ≤ D1-D2 ≤ 7 mm. This allows the mounting post 130 to be accurately inserted into the receiving hole 1202 when the lid 120 moves from the open position to the closed position, and the minimum gap between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202 is sufficiently small to prevent the gasket 200 from passing through the gap between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202 and falling off the mounting post 130. The value of D1-D2 can be 2 mm, 3 mm, 3.5 mm, 5 mm, 6 mm, etc., depending on the dimensions of the gasket 200, the mounting post 130, and the receiving hole 1202, as long as it can effectively limit the position of the gasket 200.

[0065] Furthermore, 1.2 ≤ D2 / D1 ≤ 3 can be achieved, so that when the lid 120 moves from the open position to the closed position, the mounting post 130 can be accurately inserted into the receiving hole 1202, and the minimum gap between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202 is small enough to prevent the gasket 200 from passing through the gap between the outer circumference of the mounting post 130 and the inner circumference of the receiving hole 1202 and falling off the mounting post 130. The value of D2 / D1 can be 1.5, 1.8, 2, 2.3, 2.5, etc., depending on the dimensions of the gasket 200, the mounting post 130, and the receiving hole 1202, as long as it can effectively limit the position of the gasket 200.

[0066] In the embodiment of the present application, 1.5 mm ≤ D1-D2 ≤ 7 mm and 1.2 ≤ D2 / D1 ≤ 3 can be achieved; alternatively, only 1.5 mm ≤ D1-D2 ≤ 7 mm or only 1.2 ≤ D2 / D1 ≤ 3 can be achieved. Of course, the former can further improve the limiting effect of the gasket 200.

[0067] In some embodiments, the inscribed circle diameter D1 of the radial cross-section of the receiving hole 1202 can satisfy the following condition: 2.5 mm ≤ D1 ≤ 16 mm, so that the mounting column 130 can be accurately inserted into the receiving hole 1202 while the minimum distance W between the outer peripheral surface of the mounting column 130 and the inner peripheral surface of the receiving hole 1202 is small enough to effectively limit the gasket 200.

[0068] In addition, the circumscribed circle diameter D2 of the radial cross-section of the mounting column 130 can also satisfy: 1mm≤D2≤9mm, so that the mounting column 130 can be accurately inserted into the receiving hole 1202, while the minimum distance W between the outer peripheral surface of the mounting column 130 and the inner peripheral surface of the receiving hole 1202 is small enough to form an effective limit for the gasket 200.

[0069] It should be noted that D1 and D2 may both meet the above size range, or only one of D1 and D2 may meet the above size range, depending on the size of the gasket 200 , the mounting post 130 and the receiving hole 1202 .

[0070] like Figure 1 、 Figure 2 and Figure 4 As shown, the medical device box 100 also includes a mounting plate 140 installed in the accommodating cavity 1100. The mounting plate 140 includes a mounting surface. When the box cover 120 is in the closed position, the inner surface 1201 of the box cover 120 is spaced relative to the mounting surface. The mounting surface is provided with mounting holes 141 for screws (not shown) to pass through. The screws can be installed on the mounting plate 140 by passing the screws through the mounting holes 141 of the mounting plate 140 and supporting the screw heads on the mounting surface. When the screws are needed, they can be pulled out from the mounting holes 141, which is very convenient. The screws can be cannulated nails or other types of bone screws.

[0071] Among them, the mounting column 130 can be protruded from the mounting surface to make the installation of the mounting column 130 more convenient, and the mounting column 130 is relatively close to the box cover 120, which facilitates the insertion of the mounting column 130 into the receiving hole 1202 of the box cover 120, and the operating staff can more easily remove the gasket 200 from the mounting column 130.

[0072] Of course, a mounting structure may also be provided in the accommodating cavity 1100 of the box body 110 , and the mounting post 130 may be mounted on the mounting structure, as long as the mounting post 130 can be inserted into the accommodating hole 1202 when the box cover 120 is in the closed position.

[0073] like Figure 5As shown, the housing 110 includes a first side 1102 and a second side 1103 that are opposite to each other. The lid 120 is rotatably connected to the first side 1102 of the housing 110, so that the lid 120 can rotate relative to the housing 110 between an open position and a closed position. In some embodiments, the distance between the mounting post 130 and the first side 1102 can be greater than the distance between the mounting post 130 and the second side 1103. In other words, the mounting post 130 is positioned closer to the second side 1103 of the housing 110. This allows the mounting post 130 to more accurately insert into the receiving hole 1202 when the lid 120 rotates from the open position to the closed position.

[0074] It is understood that when the box cover 120 rotates about the rotation axis L relative to the box body 110 from the open position to the closed position, the receiving hole 1202 in the box cover 120 is displaced not only in the height direction X of the box body 110, but also in the direction from the first side 1102 to the second side 1103 of the box body 110. The greater the distance between the receiving hole 1202 and the rotation axis L of the box cover 120, the smaller the displacement of the receiving hole 1202 in the direction from the first side 1102 to the second side 1103 of the box body 110 when the receiving hole 1202 moves downward by the same distance in the height direction X of the box body 110.

[0075] If the depth of the mounting post 130 inserted into the receiving hole 1202 from the time the mounting post 130 is initially inserted until the housing 110 rotates to the closed position is determined, then the amount of downward displacement of the receiving hole 1202 in the height direction X of the housing 110 is also substantially determined. During this process, the farther the receiving hole 1202 is from the rotation axis L or the first side 1102 of the housing 110, the smaller the displacement of the receiving hole 1202 from the first side 1102 to the second side 1103 of the housing 110.

[0076] Therefore, the embodiment of the present application can minimize the displacement of the receiving hole 1202 relative to the mounting post 130 in the direction from the first side 1102 to the second side 1103 of the box body 110 from the beginning of the insertion of the mounting post 130 into the receiving hole 1202 to the rotation of the box body 110 to the closed position by making the distance from the mounting post 130 to the first side 1102 greater than the distance from the mounting post 130 to the second side 1103. When the size of the receiving hole 1202 remains unchanged, the mounting post 130 can be more accurately inserted into the receiving hole 1202.

[0077] Of course, if Figure 6 As shown, the distance between the mounting post 130 and the first side 1102 can also be made smaller than the distance between the mounting post 130 and the second side 1103. In this case, the size of the receiving hole 1202 can be appropriately increased so that the mounting post 130 can be inserted into the receiving hole 1202 when the box cover 120 is rotated from the open position to the closed position.

[0078] In other embodiments, the box cover 120 may be slidably connected to the box body 110, so that the box cover 120 can slide between an open position and a closed position relative to the box body 110. Specifically, the box cover 120 can slide relative to the box body 110 along the height direction X. When the box cover 120 slides upward relative to the box body 110 a certain distance to open the opening 1101 of the box body 110, the box cover 120 is in the open position; when the box cover 120 slides downward from the open position to close the opening 1101 of the box body 110, the box cover 120 is in the closed position.

[0079] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the number of mounting posts 130 can be multiple, and multiple receiving holes 1202 can be opened on the inner surface 1201 of the box cover 120, and the multiple receiving holes 1202 correspond one-to-one to the multiple mounting posts 130. In this way, the washers 200 can be installed through the multiple mounting posts 130, which can increase the number of washers 200 that can be accommodated in the medical device box 100.

[0080] The box cover 120 can rotate relative to the box body 110 between an open position and a closed position about the rotation axis L. The plurality of mounting posts 130 can be spaced apart along the direction in which the rotation axis L extends. Alternatively, the plurality of mounting posts 130 can be sequentially distributed in a direction away from the rotation axis L, depending on the layout within the accommodating chamber 1100.

[0081] In other embodiments, the present application also provides a medical device box 100. Figures 7 to 9 As shown, the medical device case 100 includes a case body 110, a case cover 120, and mounting posts 130. The case body 110 includes a receiving chamber 1100. An opening 1101 communicating with the receiving chamber 1100 is formed at the top of the case body 110. The case cover 120 is movable relative to the case body 110 between an open position and a closed position. When the case cover 120 is in the open position, the opening 1101 is opened, and when the case cover 120 is in the closed position, the opening 1101 is closed. The mounting posts 130 are mounted within the receiving chamber 1100. The mounting posts 130 extend along the height direction X of the case body 110. The upper ends of the mounting posts 130 are configured to be inserted into the through holes of the gasket 200 so that the gasket 200 is sleeved on the mounting posts 130.

[0082] The mounting post 130 can be moved relative to the case 110 in the height direction X. Furthermore, the medical device case 100 further includes an elastic member 150 installed in the accommodating cavity 1100. The elastic member 150 is connected to the mounting post 130 and is used to drive the mounting post 130 to move upward. When the case cover 120 is in the closed position, the upper end of the mounting post 130 abuts against the case cover 120.

[0083] The medical device box 100 provided in the embodiment of the present application enables the mounting post 130 to move relative to the box body 110 in the height direction X, so that the elastic member 150 is connected to the mounting post 130 and is used to drive the mounting post 130 to move upward. When the box cover 120 is in the closed position, the upper end of the mounting post 130 abuts against the box cover 120, so that the box cover 120 can abut against the gasket 200, thereby limiting the gasket 200 to the mounting post 130 and preventing the gasket 200 from falling off the mounting post 130. Moreover, when the box cover 120 moves upward a certain distance relative to the mounting seat when it is in the closed position due to assembly precision error or deformation, the mounting post 130, under the action of the elastic member 150, the upper end of the mounting post 130 can still maintain contact with the box cover 120 to limit the gasket 200, thereby solving the problem of the existing medical device box 100 falling off the gasket 200 from the mounting post 130 when the box cover 120 is not opened due to assembly precision error or deformation of the box cover 120.

[0084] Among them, the box cover 120 includes a relative inner surface 1201 and an outer surface 1203. When the box cover 120 is in the closed position, the inner surface 1201 faces the accommodating cavity 1100, and the upper end of the mounting post 130 abuts against the inner surface 1201, so that the abutment between the upper end of the mounting post 130 and the box cover 120 is more stable, and the box cover 120 can more stably limit the gasket 200.

[0085] In other embodiments, an abutment portion may be provided on the inner surface 1201 or other position of the box cover 120, and when the box cover 120 is in the closed position, the abutment portion is located on the side of the box cover 120 facing the accommodating cavity 1100, and the upper end of the mounting post 130 abuts against the abutment portion, so as to limit the gasket 200 on the mounting post 130 through the abutment portion.

[0086] like Figures 7 to 9 As shown, the medical device case 100 also includes a mounting plate 140 mounted within the accommodating chamber 1100. The mounting plate 140 includes a mounting surface. When the case lid 120 is in the closed position, the inner surface 1201 of the case lid 120 is spaced apart from the mounting surface. The mounting surface includes mounting holes 141 for screws to pass through. Screws are installed on the mounting plate 140 by inserting them through the mounting holes 141 of the mounting plate 140, with the screw heads resting on the mounting surface. When the screws are needed, they can be simply removed from the mounting holes 141, making operation very convenient. The screws can be cannulated screws or other types of bone screws.

[0087] Among them, the mounting column 130 can be slidably connected to the mounting plate 140 along the height direction X, and the mounting column 130 is protruded from the mounting surface to make the installation of the mounting column 130 more convenient. The mounting column 130 is relatively close to the box cover 120, which facilitates the upper end of the mounting column 130 to abut against the box cover 120, and the operating staff can more easily remove the gasket 200 from the mounting column 130.

[0088] Specifically, a first sliding hole 142 extending along the height direction X can be opened on the mounting surface of the mounting plate 140, and the mounting post 130 can be slidably installed in the first sliding hole so that the mounting post 130 can be stably slidably connected to the mounting plate 140 along the height direction X.

[0089] Alternatively, a second sliding hole extending along the height direction X may be opened at the lower end of the mounting column 130, and a sliding rod extending along the height direction X may be provided on the mounting plate 140. The sliding rod is slidably installed in the second sliding hole to ensure a stable sliding connection between the mounting column 130 and the mounting plate 140 along the height direction X.

[0090] Of course, another mounting structure may be provided in the accommodating cavity 1100 of the box body 110, and the mounting post 130 may be slidably mounted on the mounting structure along the height direction X. It is only necessary to ensure that when the box cover 120 is in the closed position, the mounting post 130 can be made to abut against the box cover 120 at its upper end under the action of the elastic member 150.

[0091] In some embodiments, as Figures 7 to 9 As shown, the elastic member 150 may also be mounted on the mounting plate 140 so that the elastic member 150 can stably apply elastic force to the mounting post 130 .

[0092] Specifically, the elastic member 150 can be arranged in the first sliding hole 142 and located between the bottom surface of the first sliding hole 142 and the mounting post 130. One end of the elastic member 150 abuts against the bottom surface of the first sliding hole 142, and the other end of the elastic member 150 abuts against the lower end of the mounting post 130, so that the position of the elastic member 150 on the mounting plate 140 remains stable, and a stable upward thrust is applied to the mounting post 130, pushing the mounting post 130 to move upward to a position where the upper end of the mounting post 130 abuts against the box cover 120.

[0093] In the embodiment of the present application, the elastic member 150 may be a spring, a torsion spring, a tension spring, rubber or other elastic component, and only needs to be able to provide an upward pulling force or pushing force to the mounting post 130 .

[0094] In some embodiments, as Figure 8 and Figure 9As shown, mounting plate 140 may also be provided with a stopper 143, which is configured to abut against mounting post 130 to prevent mounting post 130 from moving upward out of first slide hole 142, or to prevent the slide bar from moving out of the second slide hole. By limiting mounting post 130 with stopper 143, excessive upward movement of mounting post 130 can be prevented, potentially leading to separation of mounting post 130 from mounting plate 140.

[0095] In which, an abutment protrusion 131 can be convexly provided on the outer peripheral surface of the mounting column 130, and the abutment protrusion 131 is located below the limiting portion 143. The limiting portion 143 abuts against the abutment protrusion 131 to limit the upward movement distance of the mounting column 130 relative to the mounting plate 140, thereby preventing the mounting column 130 from falling off the mounting plate 140.

[0096] In some embodiments, the medical device case 100 can include multiple mounting posts 130 and multiple elastic members 150. The multiple mounting posts 130 can each be movable relative to the case 110 along the height direction X, and the multiple elastic members 150 are connected to the multiple mounting posts 130 in a one-to-one correspondence. When the case lid 120 is in the closed position, the upper ends of the multiple mounting posts 130 abut against the case lid 120. Thus, the washers 200 can be mounted via the multiple mounting posts 130, thereby increasing the number of washers 200 that can be accommodated within the medical device case 100.
