[0002] Surgical bed accessories are usually used by fixing them on the side rails on both sides of the surgical bed. For ease of use, the side rails of the surgical bed generally have the following specifications: cross-section 30*10mm, 32*9mm, 30*8mm, 25*10mm, 25*8mm, etc. At present, the side rail clamps are generally fixed in size and can only be used with side rails of fixed size, and the scope of application is narrow. In addition, when installing, it is necessary to slide from the open end of the side rail to the appropriate position, and it is difficult to install and fix it through the surgical bed sheet. Therefore, it is usually only used to fix surgical bed accessories that do not require sterilization, and it is not suitable for use in surgical environments that require sterility. Therefore, there are some application deficiencies in the side rail clamp fixing device. Utility Model Content

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The same or similar reference numerals are used in the drawings to represent the same or similar modules. It should be understood that the drawings are only schematic, and the protection scope of the present application is not limited thereto.

[0026] In most cases of general surgery, obstetrics and gynecology, and urology, the patient's legs need to be spread apart and placed in the lithotomy position. The lithotomy position is the most commonly used position for anorectal surgery, urology, and gynecological surgery and examinations. The patient lies on his back on the examination bed with his buttocks placed on the leg support near the end of the bed. This can maximize the exposure of the perineum and is a common position for rectal and anal canal surgery and gynecological examinations. The leg support is an important medical device in lithotomy surgery. Traditional leg supports support the patient's popliteal leg. This type of leg support has a small support area and is prone to cause blood circulation disorders in the patient's legs. Leg supports that support the calf can avoid this secondary injury, so leg supports that support the calf are becoming more and more popular.

[0027] During knee replacement surgery, the patient's legs need to be fixed in different extension or flexion positions according to the needs of different stages of the surgery, and a knee brace is usually used to fix the patient's legs.

[0028] Leg rests, knee supports and other operating table accessories are usually fixed to the side rails on both sides of the operating table. For ease of use, the operating table side rails are generally set in the following specifications: cross-section 30*10mm, 32*9mm, 30*8mm, 25*10mm, 25*8mm, etc.

[0029] Existing side rail clamps are generally of fixed sizes and can only be used in conjunction with surgical bed side rails of fixed sizes. They have a narrow scope of application and are not universal. Also, during installation, they need to be slid from the open end of the side rail to the appropriate position. Since the gap with the side rail is small, it is difficult to install and fix it across the surgical sheet, so it is usually only used to fix surgical bed accessories that do not require sterilization. The connection between sterile accessories and the surgical bed becomes complicated and is not suitable for use in surgical environments that require sterility. In other words, the surgical sheet is a sterile environment, and the side rail clamp clamped across the surgical sheet can meet the requirements for fixing sterilized accessories. If the side rail is directly connected to the side rail without separating the surgical sheet, the sterility requirements cannot be met (the side rail is not convenient to sterilize). It can be seen that the side rail clamp fixing device has the above application deficiencies.

[0030] Therefore, it is necessary to design a technical solution for a side rail clamp that is easy to disassemble and assemble and has a wide range of applications.

[0031] Based on this, an embodiment of the present application proposes a side rail clamp. Figure 1 Schematic diagram of the side rail clamp proposed in the embodiment of the application. Figure 1 The side rail clamp of the embodiment of the present application is described in detail. The side rail clamp is generally used to fix the operating table accessories to the side rail of the operating table. Figure 1 As shown, the side rail clip 100 may include a first clamping portion 110 and a second clamping portion 120 .

[0032] The first clamping portion 110 is connected to the second clamping portion 120 .

[0033] The first clamping portion 110 and the second clamping portion 120 are used to clamp the side rails of the operating table. Figure 1 As shown by the dotted line in FIG. When the first clamping portion 110 and the second clamping portion 120 clamp the side rail, a receiving space that covers the side rail can be formed. In some embodiments, when viewed from a direction perpendicular to the end surface of the side rail (i.e., along the length direction), the first clamping portion 110 and the second clamping portion 120 can cover the four sides of the side rail cross section on the inner side.

[0034] In some implementations, the side rail clip 100 may include an adjustment device ( Figure 1 The adjusting device is used to adjust the spacing (or opening degree) between the first clamping part 110 and the second clamping part 120. The adjusting device may have a self-locking function, and may maintain the locking state of the side rail in the absence of external force.

[0035] The distance between the first clamping portion 110 and the second clamping portion 120 can be adjusted to be larger than a first dimension, where the first dimension is the distance between two opposite surfaces of the side rail being clamped. The two opposite surfaces can be, for example, the top surface and the bottom surface of the side rail, and the first dimension can be the height of the side rail. In other words, the distance between the first clamping portion 110 and the second clamping portion 120 is adjustable so that the side rail clip 100 can be installed and / or removed from the side of the side rail, without having to install and / or remove the side rail clip 100 from both ends of the side rail.

[0036] There are many ways to connect the first clamping portion 110 and the second clamping portion 120 .

[0037] In some implementations, the first clamping portion 110 and the second clamping portion 120 may be hingedly connected. The side rail clip 100 may include a first rotation axis, and the first clamping portion 110 and / or the second clamping portion 120 rotates around the first rotation axis. The hinged connection helps to reduce the height dimension of the side rail clip 100.

[0038] In some embodiments, the first rotating shaft can be disposed on the first clamping portion 110, the first rotating shaft is fixedly connected to the first clamping portion 110, and the second clamping portion 120 rotates around the first rotating shaft. In other embodiments, the first rotating shaft can be disposed on the first clamping portion 110, and both the first clamping portion 110 and the second clamping portion 120 can rotate around the first rotating shaft. The embodiments of the present application do not limit the specific structural forms of the first clamping portion 110 and the second clamping portion 120, as long as the corresponding functions can be achieved.

[0039] In the embodiment of the present application, since the distance between the first clamping portion 110 and the second clamping portion 120 can be adjusted to be larger than the distance between the two opposite surfaces of the side rail being clamped, the side rail clamp 100 can be installed and / or removed from the side of the side rail, without having to install and / or remove the side rail clamp 100 from both ends of the side rail. The side rail clamp of the embodiment of the present application is easy to assemble and disassemble, can adapt to side rails of different sizes, has a wide range of applications, and has good compatibility. The side rail clamp of the embodiment of the present application can be used to connect multiple layers of surgical sheets to the side rails, that is, it is suitable for fixing surgical bed accessories that do not require sterilization, and is also suitable for surgical environments that require sterility.

[0040] In some implementations, the first clamping portion 110 may be provided with a first clamping jaw, which may be a fixed clamping jaw, or the first clamping portion 110 and the first clamping jaw are made in one piece. The second clamping portion 120 may be provided with a second clamping jaw, which may be a fixed clamping jaw, or the second clamping portion 120 and the second clamping jaw are made in one piece. When the first clamping portion 110 and the second clamping portion 120 clamp the side rail, the first clamping jaw covers the first side surface of the side rail on the inner side and contacts the two side lines of the first side surface, and the second clamping jaw covers the second side surface of the side rail on the inner side and contacts the two side lines of the second side surface, and the second side surface is opposite to the first side surface.

[0041] In some implementations, the first clamping part 110 and the second clamping part 120 can rotate relative to each other. When the width and / or height of the side rail are different, the center line of the clamping jaw of the first clamping part 110 and the center line of the clamping jaw of the second clamping part 120 may not be perpendicular to the clamping surface of the side rail, or the fit is poor, which will affect the clamping effect. In some embodiments, the first clamping part 110 can be provided with a first clamping jaw, the first clamping jaw can be a fixed clamping jaw, or the first clamping part 110 and the first clamping jaw are made in one piece. The second clamping part 120 can be provided with a second rotating shaft and a second clamping jaw hingedly connected to the second rotating shaft, and the axis of the second rotating shaft is parallel to the axis of the first rotating shaft. When the first clamping part 110 and the second clamping part 120 clamp the side rail, the first clamping jaw covers the first side surface of the side rail on the inner side and contacts the two side lines of the first side surface, and the second clamping jaw covers the second side surface of the side rail on the inner side and contacts the two side lines of the second side surface, and the second side surface is opposite to the first side surface.

[0042] When clamping the side rail, the second clamping jaw should be in a fixed state and should not shake. In some implementations, a limiting surface can be provided on the second clamping portion 120 to limit the rotation range of the second clamping jaw so that it can rotate around the second rotation axis within a certain range. The limiting surface can be, for example, a limiting block. The limiting surface can be fixed or adjustable.

[0043] In some implementations, the first clamping jaw may be an arc-shaped structure or a V-shaped structure, and / or the second clamping jaw may be an arc-shaped structure or a V-shaped structure, which helps to keep the clamping jaw in contact with both sides of the clamping surface of the side rail during clamping. In some embodiments, the arc-shaped structure may be, for example, a semicircular structure or an elliptical structure. The size of the semicircular structure may be set accordingly according to the size of the side rail.

[0044] In some implementations, the side rail clamp 100 may include an adjustment device. The adjustment device may include a locking block, a first rotating seat, and a screw. The locking block is hingedly connected to the first rotating shaft, and the locking block is located outside the first clamping portion 110 and the second clamping portion 120. The locking block is a mounting bracket of the adjustment device, and a mounting hole for fixing the first rotating seat is provided on the locking block. The first rotating seat is installed in the locking block and hingedly connected to the locking block. The first rotating seat is provided with a threaded through hole, and the axis of the first rotating seat is parallel to the axis of the first rotating shaft, and the axis of the threaded through hole is perpendicular to the axis of the first rotating seat. The axis of the first rotating seat is the rotation centerline of the first rotating seat. The screw is provided with an external thread, and the screw is connected to the threaded through hole of the first rotating seat. One end of the screw is connected to the second rotating seat, and the second rotating seat is located in the second clamping portion 120 and hingedly connected to the second clamping portion 120, and the axis of the second rotating seat is parallel to the axis of the first rotating seat. The axis line of the second rotating seat is the rotation center line of the second rotating seat.

[0045] The side rail clamp usually fixes the operating table accessories to the side rails of the operating table through an adapter. The operating table accessories can be, for example, a leg support or a knee support. In some implementations, there is a gap between the first clamping portion 110 and the locking block, and the gap is used to accommodate the first side plate of the adapter. The screw is used to adjust the gap so that the first clamping portion 110 and the locking block clamp the first side plate. The adapter is used to connect to the bracket of the operating table accessories.

[0046] In some implementations, the side rail clamp 100 may include an elastic member, which is located between the first clamping portion 110 and the second clamping portion 120, and the elastic member is used to put the first clamping portion 110 and the second clamping portion in a compressed state. In other words, the elastic member makes the first clamping portion 110 and the second clamping portion similar to an elastic clamp structure. The elastic member may be, for example, a torsion spring, and under the action of the torsion spring force, the clamp is in a closed state, and the side rail clamp 100 can be hung on the side rail without falling. On the other hand, since the first clamping portion 110 and the second clamping portion are always under pressure from the elastic member, the gap between the first clamping portion 110 and the locking block is large, which is convenient for loading the first side plate of the adapter. It can be understood that in the process of adjusting the screw to make the side rail clamp 100 clamp the side rail, the first clamping portion 110 and the second clamping portion are always under pressure to contact the side rail, so that the first clamping portion 110 and the second clamping portion lock the side rail, and the first clamping portion 110 and the locking block lock the first side plate of the adapter.

[0047] In some implementations, the first clamping portion 110 and the locking block are both provided with a protrusion (or operating portion), which is used for the user to pinch and open the first clamping portion 110 and the second clamping portion 120. Since the second clamping portion 120 and the locking block are fixedly connected when the screw is not adjusted, the user can quickly open the elastic clamp structure composed of the first clamping portion 110 and the second clamping portion 120 by pinching the protrusion, so as to clamp the side rail clip 110 on the side rail of the operating table or quickly remove it. Under the action of the torsion spring force, the elastic clip is in a closed state and can be hung on the side rail without falling.

[0048] In some implementations, the first clamping portion 110 and the second clamping portion 120 may be slidably connected. There may be various ways of slidably connecting. For example, the adjusting device may be fixed on the first clamping portion 110, and the adjusting device and the second clamping portion 120 may be threadedly connected, and the thread may be, for example, a self-locking thread. For another example, the adjusting device may include a nut seat and a bidirectional screw, and the nut seat may be mounted on a fixing frame, and the bidirectional screw is respectively connected to the first clamping portion 110 and the second clamping portion 120, and by rotating the bidirectional screw, the first clamping portion 110 and the second clamping portion 120 may simultaneously approach or move away from each other in the same direction.

[0049] In some implementations, the side rail may be any of a plurality of side rails with different heights and / or widths. In other words, the side rail clip 100 is applicable to any of a plurality of side rails with different heights and / or widths. The cross-sectional dimensions of the side rail may be, for example, 30*10mm, 32*9mm, 30*8mm, 25*10mm, 25*8mm, etc.

[0050] In the embodiment of the present application, since the distance between the first clamping portion 110 and the second clamping portion 120 can be adjusted to be larger than the distance between the two opposite surfaces of the side rail being clamped. Therefore, the side rail clamp 100 can be installed and / or removed from the side of the side rail, without having to install and / or remove the side rail clamp 100 from both ends of the side rail. The side rail clamp of the embodiment of the present application is easy to assemble and disassemble, can adapt to side rails of different sizes, has a wide range of applications, and has good compatibility. The side rail clamp of the embodiment of the present application can be used to connect multiple layers of surgical sheets to the side rails, and is suitable for fixing surgical bed accessories that do not require sterilization, and is also suitable for surgical environments that require sterility.

[0051] The embodiments of the present application are further described below in conjunction with some possible implementation methods of the embodiments of the present application.

[0052] Figure 2 yes Figure 1 Schematic diagram of a possible implementation of the side rail clamp. Figure 2As shown, the side rail clamp 200 may include: a first clamping portion 110 , a second clamping portion 120 , a first rotating shaft 230 , and an adjusting device 240 .

[0053] The first clamping part 110 and the second clamping part 120 can rotate around the first rotating shaft 230. The first clamping part 110 and the second clamping part 120 are used to clamp the side rail of the operating table. The distance between the first clamping part 110 and the second clamping part 120 can be adjusted to be larger than a first dimension, and the first dimension is the distance between two opposite surfaces of the side rail being clamped. The two opposite surfaces can be, for example, the top surface and the bottom surface of the side rail, and the first dimension can be the height of the side rail.

[0054] The adjusting device 240 is used to adjust the distance (or opening degree) between the first clamping portion 110 and the second clamping portion 120. The adjusting device 240 may have a self-locking function, and may maintain the locking state of the side rail in the absence of external force.

[0055] The adjusting device 240 may include a locking block 241 , a first rotating seat 242 and a screw rod 243 .

[0056] The locking block 241 is hingedly connected to the first rotating shaft 230, and the locking block 241 is located outside the first clamping portion 110 and the second clamping portion 120. The locking block 241 is a mounting bracket of the adjusting device 240, and a mounting hole for fixing the first rotating seat 242 is provided on the locking block 241. The first rotating seat 242 is installed in the locking block 241 and is hingedly connected to the locking block 241. The first rotating seat 242 can rotate in the mounting hole corresponding to the locking block 241. The first rotating seat 242 is provided with a threaded through hole. The axis of the first rotating seat 242 is parallel to the axis of the first rotating shaft 230, and the axis of the threaded through hole is perpendicular to the axis of the first rotating seat 242. Since the first rotating seat 242 is provided with a threaded through hole, the first rotating seat 242 is also called a threaded rotating seat.

[0057] The screw 243 is provided with an external thread, and the external thread matches the threaded through hole of the first rotating seat 242, that is, the screw 243 is connected to the threaded through hole of the first rotating seat 242. One end of the screw 243 is connected to the second rotating seat 244, and the second rotating seat 244 is located in the second clamping part 120 and is hingedly connected to the second clamping part 120. The second rotating seat 244 can rotate in the mounting hole corresponding to the second clamping part 120, and the axis of the second rotating seat 244 is parallel to the axis of the first rotating seat 242. The axis of the second rotating seat is the rotation center line of the second rotating seat. Since the second rotating seat 244 is provided with a light hole inside, the second rotating seat 244 is also called a light hole rotating seat, and the axis of the light hole is perpendicular to the axis of the second rotating seat 244. The screw 243 passes through the light hole in the second rotating seat 244 and is connected to the second rotating seat 244.

[0058] Figure 3 yes Figure 2 A cross-sectional view of a side rail clamp. Figure 4 yes Figure 2 An exploded schematic diagram of the side rail clamp of FIG. shows a connection method between the screw rod 243 and the second rotating seat 244. Figure 3 , Figure 4 As shown, the ends of the second rotating seat 244 and the screw rod 243 are matched with an axial hole (bright hole), and the screw rod 243 is provided with an axial shoulder on one side of the matching position, and the screw rod 243 is provided with an external thread at the end near the second rotating seat 244 for installing a limit nut 245. The screw rod 243 is threadedly connected to the first rotating seat 242, and when the screw rod 243 does not rotate, a limit is inevitably formed along the axial direction of the screw rod 243.

[0059] return Figure 2 ,like Figure 2 As shown, the first clamping portion 110, the second clamping portion 120 and the locking block 241 are hinged via the first rotating shaft 230 and can rotate relative to each other.

[0060] There is a gap between the first clamping part 110 and the locking block 241, and the gap is used to accommodate the first side plate of the adapter 520. The screw 242 can be used to adjust the gap so that the first clamping part 110 and the locking block 241 clamp the first side plate. The adapter 520 is used to connect with the bracket of the operating bed accessory. The adapter 520 can be used as a transfer structure to establish a connection with other operating bed accessories, so that other operating bed accessories are rigidly connected to the operating bed.

[0061] Since the second rotating seat 244 is installed in the hole of the second clamping part 120 and can rotate, the first rotating seat 242 is installed in the hole of the locking block 241 and can rotate. Taking the first clamping part 110 as a reference, when locking the side rail, the screw 243 rotates the locking block 241 toward the second clamping part 120 through the first rotating seat 242, so that the part of the locking block 241 close to the first clamping part 110 contacts the adapter 520 (such as Figure 5 The adapter 520 is clamped by the second rotating seat 244. At the same time, the screw 243 rotates the second clamping part 120 toward the first clamping part 110 through the second rotating seat 244, so that the upper and lower clamping parts clamp the side rail. In other words, when the operating handle 246 rotates the screw 243, under the action of the thread feed force, the second clamping part 120 and the locking block 241 rotate toward or away from each other with the first rotating shaft 230 as the rotation center, and successively lock the side rail 310 and the adapter 520, and finally the adapter 520 is rigidly fixed on the operating table.

[0062] The side rail clamp 100 may include a torsion spring 250, which is located between the first clamping portion 110 and the second clamping portion 120. The torsion spring 250 is used to put the first clamping portion 110 and the second clamping portion in a compressed state. If there is no torsion spring 250, the first clamping portion 110 is located between the second clamping portion 120 and the locking block 241, and can rotate around the first rotating shaft 230 without being constrained. In other words, the torsion spring 250 makes the first clamping portion 110 and the second clamping portion similar to an elastic clamp structure. Under the action of the torsion spring force, the elastic clamp is in a closed state, and the side rail clamp 200 can be hung on the side rail without falling. On the other hand, since the first clamping portion 110 and the second clamping portion are always under pressure from the elastic member, the gap between the first clamping portion 110 and the locking block is relatively large, which is convenient for loading the first side plate of the adapter 520. It can be understood that, in the process of adjusting the screw 243 to make the side rail clamp 100 clamp the side rail, the first clamping portion 110 and the second clamping portion 120 are always under pressure to contact the side rail, so that the first clamping portion 110 and the second clamping portion 120 lock the side rail in turn, and the first clamping portion 110 and the locking block 241 lock the first side plate of the adapter 520.

[0063] The first clamping part 110 and the locking block 241 are both provided with a protrusion 112 (or an operating part), and the protrusion 112 is used for the user to pinch to open the first clamping part 110 and the second clamping part 120. Since the second clamping part 120 and the locking block 241 are fixedly connected when the screw rod 241 is not adjusted, the user can quickly open the elastic clamp structure composed of the first clamping part 110 and the second clamping part 120 by pinching the protrusion, and clamp the side rail clip 200 on the side rail of the operating table or quickly remove it. Under the action of the torsion spring force, the elastic clip is in a closed state and can be hung on the side rail without falling.

[0064] When the width and / or height of the side rails are different, the center lines of the clamping jaws of the first clamping portion 110 and the clamping jaws of the second clamping portion 120 may not be perpendicular to the clamping surface of the side rail, which will affect the clamping effect.

[0065] The first clamping part 110 may be provided with a first clamping jaw 111, and the first clamping jaw 111 may be a fixed clamping jaw, or the first clamping part 110 and the first clamping jaw 111 may be made in one piece. Since the first clamping jaw 111 is a fixed clamping jaw, the first clamping part 110 may be referred to as a fixed clamping part. The second clamping part 120 may be provided with a second rotating shaft 122 and a second clamping jaw 121 hingedly connected to the second rotating shaft 122, and the axis of the second rotating shaft 122 is parallel to the axis of the first rotating shaft 230. Since the second clamping jaw 121 is a rotating clamping jaw, the second clamping part 120 may be referred to as a rotating clamping part. When the first clamping part 110 and the second clamping part 120 clamp the side rail, the first clamping jaw 111 covers the first side surface of the side rail on the inner side and contacts the two side lines of the first side surface, and the second clamping jaw 121 covers the second side surface of the side rail on the inner side and contacts the two side lines of the second side surface, and the second side surface is opposite to the first side surface.

[0066] The second clamping jaw 121 is hinged to the second clamping portion 120 through the second rotating shaft 122, and can rotate around the second rotating shaft 122 within a certain range. A limited position surface is provided on the second clamping portion 120 to limit the rotation range of the second clamping jaw 121. In this way, during the clamping process, the second clamping jaw 121 can adaptively contact the two lower side lines of the side rail to achieve the clamping function.

[0067] In an optional embodiment, the first clamping jaw and the second clamping jaw are both movable clamping jaws hinged to the corresponding clamping portion. In another optional embodiment, the first clamping jaw and the second clamping jaw are both fixed clamping jaws.

[0068] The first clamping jaw 111 may be an arc-shaped structure or a V-shaped structure, and / or the second clamping jaw 121 may be an arc-shaped structure or a V-shaped structure, which helps to keep the clamping jaw in contact with both sides of the clamping surface during clamping. In some embodiments, the arc-shaped structure may be, for example, a semicircular structure or an elliptical structure. The size of the semicircular structure may be set accordingly according to the size of the side rail.

[0069] In the embodiment of the present application, since the distance between the first clamping portion 110 and the second clamping portion 120 can be adjusted to be larger than the distance between the two opposite surfaces of the side rail being clamped. Therefore, the side rail clamp 100 can be installed and / or removed from the side of the side rail, without having to install and / or remove the side rail clamp 100 from both ends of the side rail. The side rail clamp of the embodiment of the present application is easy to assemble and disassemble, can adapt to side rails of different sizes, has a wide range of applications, and has good compatibility. The side rail clamp of the embodiment of the present application can be used to connect multiple layers of surgical sheets to the side rails, and is suitable for fixing surgical bed accessories that do not require sterilization, and is also suitable for surgical environments that require sterility.

[0070] According to the bottom plate structure of the knee joint support frame, in some embodiments, the adapter device may be provided with a locking mechanism to lock the connection between the adapter device and the bottom plate portion of the knee joint support frame. In other embodiments, the adapter device may not be provided with a locking mechanism, and the connection between the adapter device and the bottom plate portion of the knee joint support frame is locked by using the locking mechanism on the knee joint support frame.

[0071] Figure 5 yes Figure 2 A schematic diagram of a possible connection method between the side rail clip and the side rail. Figure 5 As shown, the adapter 520 is used in conjunction with the side rail clamp 200, and the adapter 520 is used to connect and fix the bottom plate portion of the knee joint support frame 510 to the side rail 530 of the operating table. In other words, the side rail clamp 200 fixes the knee joint support frame 510 to the side rail 530 of the operating table through the adapter 520, thereby achieving a rigid connection between the knee joint support frame 510 and the side rail 530.

[0072] Figure 6a yes Figure 5 A schematic diagram of a possible implementation of the switching device in FIG. Figure 6b 5 is a cross-sectional view of the adapter 520. The adapter 520 is used in conjunction with the side rail clamp to connect and fix the bottom plate portion of the knee joint support frame to the side rail of the operating table. Figure 6a , Figure 6b As shown, the adapter 520 may include an adapter plate 521, a top screw 522, a handle 523, a spring 524 and a stop ring 525. The top screw 522, the handle 523, the spring 524 and the stop ring 525 constitute a locking mechanism, which is used to lock the adapter 520 with the bottom plate of the knee joint support frame.

[0073] The adapter plate 521 is an L-shaped adapter plate, that is, the adapter plate 521 can be composed of a first side plate 5211 and a second side plate 5212, the first side plate 5211 and the second side plate 5212 are perpendicular, and the adapter plate 521 can be an integrally formed part. The first clamping portion 110 of the side rail clamp 200 is hinged to the locking block 241 to form a cavity for accommodating and locking the first side plate 5211 (usually the long side) of the L-shaped adapter plate 521. The second side plate 5212 of the L-shaped adapter plate 521 can be in the form of a U-shaped groove, and the second side plate 5212 is used to buckle on the bottom plate of the knee joint support frame. A threaded hole is provided on the side of the L-shaped adapter plate 521 to accommodate the top screw 522. The second side plate 5212 matches the knee joint support frame or the bottom plate of the knee joint support frame, and the specific structure of the second side plate 5212 is not limited in the embodiment of the present application.

[0074] A handle 523 is sleeved on the top screw 522, and the handle 523 is used to adjust the top screw 522. The junction of the handle 523 and the top screw 522 is a mating surface. The mating surface can have various types, such as a polygon, a spline, or a tooth shape. Figure 6a As shown, the inner teeth in the hole of the handle 523 mesh with the outer teeth on the shaft of the top screw 522 under the action of the reset spring 524 to transmit the locking force. The top screw 522 can be driven to press against the bottom plate of the knee joint support frame by turning the handle. If the position of the handle 523 after locking is not suitable, the spring force can be overcome to pull the handle 523 axially to disengage the teeth and then rotate the handle 523 to the required angle. A limiting boss is set at one end of the top screw 522 where the spring 524 is installed, and a limiting ring 525 is set at the other end to block the reset spring to form an anti-falling structure. The limiting ring 525 can be welded or a retaining ring.

[0075] Figure 7 yes Figure 1 Schematic diagram of one possible application of the rail clip. Figure 7 As shown, the operating table support assembly 700 may include: a knee joint support frame 510 , a switching device 520 and a side rail clamp 200 .

[0076] Since the opening degree of the side rail clamp 200 is easy to adjust, the knee joint support frame 510 can be adjusted in the first dimension (i.e., the length direction of the side rail). The height of the first side plate 5211 of the adapter 520 is adjustable, which can achieve the adjustment of the knee joint support frame 510 in the second dimension (i.e., the vertical direction). The second side plate 5212 of the adapter 520 is in the form of a U-shaped groove, which is buckled on the bottom plate of the knee joint support frame 510, and the second side plate 522 is provided with the above-mentioned locking mechanism. It helps to adjust the knee joint support frame 510 along the width direction of the operating bed, that is, to adjust the third dimension. It can be seen that the support assembly 700 has the function of adjusting the position in three directions (i.e., along the length direction of the side rail, the height direction, and the width direction of the operating bed), which is convenient and flexible to adjust the position to fix the knee joint support frame 510, and then flexibly and reliably fix the patient's leg in a suitable position.

[0077] Figure 8a yes Figure 2 Schematic diagram of another possible connection method of the side rail clip to the side rail. Figure 8b yes Figure 8a A partial enlarged schematic diagram of Figure 8a , Figure 8bAs shown, the knee joint support frame 810 has a locking mechanism 811, which may be a cam handle structure. The adapter 820 is an L-shaped structure, and the adapter 820 may not be provided with a locking mechanism, but the locking mechanism 811 is used to fix the upper side plate (second side edge) of the adapter 820 to the bottom plate of the knee joint support frame 810. The side rail clamp 200 fixes the other side plate of the adapter 820 to the side rail of the operating table, thereby realizing a rigid connection between the knee joint support frame 810 and the side rail.
