Abstract
Description
Technical Field
[0001] This disclosure generally relates to a clamp for attaching a medical device to a structure, and particularly to a spring-actuated clamp for attaching an infusion pump to an intravenous infusion line (IV) rod. Background Technology
[0002] Medical devices can be attached to different structures as needed. Existing solutions for attaching medical devices to structures use manual clamps, which require the user to adjust the torque applied to the structure via the clamps. The torque applied via the manual clamps may be inconsistent, which can lead to non-rigid clamping or excessive torsion. This can cause the medical device to fall or slip off the structure, make it difficult to remove the medical device from the structure, or damage the structure.
[0003] Therefore, there is a need for a clamp that provides a consistent force for attaching a medical device to a structure. Summary of the Invention
[0004] The disclosed subject matter relates to a spring-actuated clamp configured to engage a medical device (such as an infusion pump) with a structure. This spring-actuated clamp is easy to use, reduces or eliminates user errors, reduces the time and effort required to engage the medical device with the structure, allows the medical device to be engaged at different heights, and reduces or eliminates damage to the structure. The spring-actuated clamp is configured to hold the mechanism (e.g., the medical device) in place and ensures that the correct amount of force is applied each time the mechanism is engaged (e.g., clamped) with the structure.
[0005] According to some embodiments, a clamping device is provided. The clamping device includes a clamping body and a clamping mechanism. The clamping body includes an opening with a slot extending through at least a portion of its inner wall. The slot is configured to prevent the clamping member from passing through the opening when a protruding key member of the clamping member is not aligned with the slot. The clamping mechanism includes: a clamping member extending through the opening; a fastener coupled to a first portion of the clamping member on a first side of the opening, adjacent to a first end of the clamping member; a hand member coupled to a second end of the clamping member, opposite to the first side of the opening and opposite to the first end; a protruding key member extending from the second portion of the clamping member and configured to be received via the slot; and a spring element disposed on the clamping member between the fastener and the first side of the opening, such that the spring element is compressed or extended between the fastener and the first side of the opening when the position of the clamping mechanism changes. The second portion is located at a middle portion of the clamping member, between the first and second ends of the clamping member. When the clamping mechanism is in the pre-engaged position, the spring element is at a first compression length to disengage the medical device from the structure. When the clamping mechanism is in the engaged position, the spring element is at a second compression length, causing the clamping member to extend through the opening to engage the structure and connect the medical device to it. The second compression length is greater than the first compression length.
[0006] According to some embodiments, a system includes a medical device and a clamping device coupled to the medical device. When the clamping mechanism of the clamping device is in a pre-engaged position, a spring element of the clamping mechanism is in a first compression length for disengaging the medical device from the structure. When the clamping mechanism of the clamping device is in an engaged position, the spring element of the clamping mechanism is in a second compression length, causing a clamping member to extend through an opening to engage the structure, thereby coupling the medical device to the structure. The second compression length is greater than the first compression length.
[0007] According to some embodiments, a method for coupling a medical device to a structure using a clamping device includes: adjusting a clamping mechanism of the clamping device to a pre-engaged position, such that when the clamping mechanism is in the pre-engaged position, a spring element of the clamping mechanism is at a first compression length, creating a gap. This gap is configured to receive the structure or disengage the medical device from the structure. The method further includes: coupling the clamping device to the structure; aligning a protruding key member of the clamping mechanism with a slot in the clamping body of the clamping device to allow the clamping mechanism to move from the pre-engaged position to an engaged position; and adjusting the clamping mechanism to the engaged position. When the clamping mechanism is in the engaged position, a spring element of the clamping mechanism is at a second compression length, such that a clamping member of the clamping mechanism extends through an opening to engage the structure, thereby coupling the medical device to the structure. The second compression length is greater than the first compression length.
[0008] According to some embodiments, a method for forming a clamping device includes: providing a clamping body; providing a clamping mechanism; and coupling the clamping body to the clamping mechanism. The clamping body includes an opening, the opening including a slot through at least a portion of an inner wall of the opening. The slot is configured to prevent the clamping member from passing through the opening when a clamping member passes through the opening and a protruding key member of the clamping member is not aligned with the slot. The clamping mechanism includes: a clamping member extending through the opening; a fastener coupled to a first portion of the clamping member on a first side of the opening, adjacent to a first end of the clamping member; a hand member coupled to a second end of the clamping member, opposite to the first side of the opening and opposite to the first end; a protruding key member extending from the second portion of the clamping member and configured to be received via the slot; and a spring element disposed on the clamping member between the fastener and the first side of the opening. The second portion is located at a middle portion of the clamping member, between the first and second ends of the clamping member.

[0018] Figure 1 An IV pump for administering medical fluid to a patient is shown. The IV pump 30 includes a controller 32 and one or more pump modules 34. An IV kit 20 is connected between a container 36 (e.g., an IV bag) containing the medical fluid and the patient 5. During operation, the IV pump 30 delivers the medical fluid to the patient 5. The IV pump 30 is configured to administer the medical fluid to the patient at a predetermined and uniform rate. In some embodiments, the IV kit 20 is used to further accelerate the flow of the medical fluid from the container 36 (or the IV pump 30) to the patient. For example, a manual pump fluidly connected to the container 36 and / or the IV kit 20 can be used to further accelerate the flow of the medical fluid.
[0019] Figures 2A-2C A clamping device coupled to a medical device is shown according to some embodiments. The clamping device 210 includes a clamping body 215 and a clamping mechanism 220. The clamping device 210 is coupled to a medical device 205 (similar to a controller 32 and one or more pump modules 34). Figure 1 The clamping device 210 is connected and configured to mount the medical device 205 to a structure 255 (such as an IV rod, column, wall, etc.). The clamping device 210 includes a mounting fastening device 311 that connects the clamping device 210 to the medical device 205 via a mounting surface 207. The mounting fastening device 311 of the clamping device 210 aligns an opening 307 of the clamping device 210 with a (planar) surface 206 of the medical device 205, such that the opening 307 is perpendicular to the surface 206 of the medical device 205. By positioning the opening 307 of the clamping device 210 perpendicular to the surface 206 of the medical device 205, the clamping member 325 of the clamping device 210 applies a direct linear compressive force to the structure 255 between the clamping member 325 and the surface 206 of the medical device 205. The clamping device 210 is referenced below. Figures 3A-3D Detailed discussion. Although the surface 206 of the medical device 205 is described as a planar surface, in some embodiments, the surface 206 is a recess, compartment, slot, curved portion, hollow portion, and / or other surface of the medical device 205, and the structure 255 can be pushed against said surface such that the force pushing the structure 255 into the medical device 205 (e.g., applied by the clamping mechanism 210) engages the medical device 205 with the structure 255.
[0020] In some embodiments, the clamping device 210 (including its components) is formed of low-carbon steel. The clamping body 215 and the clamping mechanism 220 are referenced below. Figures 3A-3D Let's discuss this in detail.
[0021] In the initial position 200, the clamping mechanism 220 is not engaged, and the clamping component 325 ( Figure 3C (e.g., screws, rods, etc.) are fully inserted into the clamp body 215 (e.g., via opening 307); Figure 3A and Figure 3B The clamping mechanism 220 has a free length substantially equal to the length of the clamping member 325. A spring element 335 is disposed on a portion of the clamping mechanism 220, located between the protruding key member 340 and the fastener 330. Figure 3C and Figure 3D (Uncompressed)
[0022] In the pre-engaged position 230, the clamping mechanism 220 is pulled back (e.g., via the hand member 329); Figure 3C and Figure 3DThe spring element 335 is compressed between the clamp body 215 and the fastener 330. The force required to pull back the clamp mechanism 220 is based on the spring stiffness of the spring element 335. Spring stiffness is the amount of force required per inch of compression. The higher the spring stiffness, the greater the force required to pull back the clamp mechanism 220 and compress the spring element 335. When a force is applied to the spring element 335 (e.g., compressing the spring element 335), the spring element 335 is compressed by a certain compression length (e.g., based on the distance the clamp mechanism 220 is pulled back). In some embodiments, the spring stiffness is selected such that the compression length is a predetermined length based on the structure to which the clamp device 210 is configured to be coupled. For example, the structure may be an IV bar 255 with a predetermined radius, and the spring stiffness may be selected such that after reaching the compression length required to connect the clamp device 210 to the IV bar 255, the clamp mechanism 220 is substantially more difficult for the user to pull back. Alternatively or additionally, in some embodiments, the protruding key member 340 of the clamping mechanism 220 may be positioned at a predetermined location on the clamping member 325 based on a predetermined radius of the IV bar 255, as referenced below. Figure 3D It was discussed in detail.
[0023] In the engaged position 250, the clamping mechanism 220 is released, causing it to apply a force to the structure (e.g., IV bar 255). Specifically, upon release, the clamping mechanism 220 attempts to return to its uncompressed state (e.g., free length) and applies a force to the IV bar 255 to engage the medical device 205 with the IV bar 255. The force applied by the clamping mechanism 220 is based on spring stiffness. Specifically, the spring element 335 attempts to return the clamping mechanism 220 to the initial position 200 and drive the clamping mechanism 220 into the IV bar 255.
[0024] In some embodiments, the clamping device 210 is configured to support a weight of at least 9.5 kg. For example, the clamping device 210 can attach a medical device of at least 9.5 kg to the IV bar 255. In some embodiments, the spring stiffness and / or the compressed length of the spring element 335 can be adjusted to support more or less weight.
[0025] Figures 3A-3D A clamping device 210 according to some embodiments is shown. Figures 2A-2C Different parts of ). Figure 3A and Figure 3B Different views of the clamp body 215 are shown. Figure 3C A first embodiment of the clamping mechanism 220 is shown, while Figure 3D Another example of a clamping mechanism 350 is shown.
[0026] First view 305 shows an opening 307 in the clamp body 215. The opening 307 (e.g., a hole, orifice, etc.) is configured to receive the clamp mechanism 220 and allow the clamping member 325 of the clamp mechanism 220 to travel substantially through the opening 307. Specifically, the opening 307 allows the clamping member 325 of the clamp mechanism 220 to travel from an initial position 200 (…). Figure 2A (e.g., free length) travels to the pre-engagement position 230 ( Figure 2B (e.g., compressed length). The opening 307 includes one or more slots 309 (e.g., keyways or entry points). The slots 309 are configured to control the travel of the clamping member 325 via the opening 307. Specifically, when the protruding key member 340 of the clamping member 325 is aligned with the slot 309, the slot 309 allows the clamping member 325 to travel via the opening 307, as referenced below. Figures 4A-4E The slot 309 can be positioned along the inner wall of the opening 307. As shown, two slots 309 can be positioned opposite each other to form a channel 317 extending through the center point of the opening, the channel 317 being longer than the diameter of the opening 307 (e.g., the length "L" of the channel 317 is greater than the diameter "d" of the opening 307). In some embodiments, the slot 309 can be positioned at other points within the opening 307, and / or the opening 307 may include one or more slots.
[0027] The clamp body 215 further includes a mounting and fixing device 311 for connecting the clamp body 215 to the medical device 205. Figures 2A-2C As shown in the figure, the mounting and fixing device 311 may include another opening for securing the clamp body 215 to a portion of the medical device 205 (e.g., bolts or other mounting fasteners located on surface 207 of the medical device 205, such as a side wall or rear portion of the medical device 205). Figure 3B As depicted, another opening of the mounting fastener 311 (or mounting mechanism) may be offset at a right angle (e.g., 90 degrees) from opening 307, such that during installation, opening 307 is offset by 90 degrees from the mounting surface 207 of the medical device 205, allowing the clamping member 325 to be perpendicular to the surface 206 of the medical device 205. Specifically, opening 307 is located on a first surface 301 of the clamping body 215, and mounting fastener 311 is located on a second surface 303 of the clamping body 215 perpendicular to the first surface. In some embodiments, opening 307 may be secured by bolts or mounting fasteners (see reference below). Figure 3C and Figure 3D (The described clamping mechanism) is used instead.
[0028] In addition, such as Figure 3AAs shown, opening 307 is located at a different height (e.g., height difference "h") from mounting fixture 311. Opening 307 may be at a predetermined angle (θ) (e.g., 45 degrees) with the centerline of the arm of the first face 301. Opening 307 is also located at a predetermined distance (x) extending from the end of the first face 301 (e.g., near the end of the second face 303). This allows opening 307 to be aligned with the planar surface 206 of the medical device 205, and / or to align opening 307 with the planar surface 206 on the medical device 205.
[0029] Second view 315 shows an opening 307, one or more slots 309, channels 317, and grooves 319 in the clamp body 215. As described above, the channel 317 defines an internal passage within the clamp body 215 such that the clamp member 325 can traverse the opening 307 when the protruding key member 340 of the clamp member 325 is aligned with the slot 309. For example, as shown in second view 315, the channel 317 (and the opening 307) extends the entire thickness (t) of the clamp body 215, including a portion of the opening 307, such that the clamp member 325 can traverse the opening 307.
[0030] In some embodiments, a groove 319 is disposed within the opening 307 and perpendicular to the channel 317. The groove 319 may be disposed along a middle portion of the channel 317 (e.g., a portion of the thickness (t) of the channel 317 extending from the portion of the clamp body 215 that includes the opening 307). For example, as shown in the second view 315, the groove 319 is disposed at the midpoint of the thickness (t) within the opening 307. The groove 319 may surround the inner wall of the opening 307 and / or define an inner circumference within the opening 307. The groove 319 is configured to receive the protruding key member 340 and lock the clamp member 325 in a predetermined position. Specifically, refer to the following... Figures 4A-4E As described in detail, when the protruding key member 340 is aligned with the groove 319, the clamping mechanism 220 can rotate so that the protruding key member 340 enters the groove 319 and the clamping member 325 is no longer able to cross the opening 307, thereby locking the clamping member in place (e.g., at a predetermined compression length).
[0031] As shown in the second view 315, the mounting and fixing device 311 includes another opening offset from the opening 307 by a predetermined angle (e.g., 90 degrees). The mounting and fixing device 311 attaches the clamp body 215 to the mounting surface 207 of the medical device 205. Figures 2A-2CSpecifically, another opening in the mounting fastener 311 is configured to receive a fastener that attaches the clamp body 215 to the medical device 205. The fastener may be a bolt, threaded rod, or other fastening device for attaching the clamp body 215 to the medical device 205. As previously described, the mounting fastener 311 may include fasteners (e.g., bolts, threaded rods, bars, etc.), and the medical device may include an opening for receiving the fastener.
[0032] like Figure 3C As shown, the clamping mechanism 220 includes a clamping member 325, a fastener 330, a hand member 329, one or more protruding key members 340, and a spring element 335. The clamping member 325 extends through an opening (e.g., a predetermined length, such as the length of the clamping body 215 or a predetermined free length) and includes a first end 327 that contacts the structure and / or applies a compressive force to the structure (e.g., for mounting a medical device 205) and a second end that engages with the hand member 329. When engaged (e.g., the clamping member 325 travels through the opening 307), the first end 327 compresses the structure (e.g., IV bar 255) against the medical device 205, thereby mounting the medical device 205 onto the structure.
[0033] As described above, by offsetting the opening 307 by 90 degrees from the mounting fixture 311 (e.g., relative to the first face 301 and the second face 303), the clamping member 325 is perpendicular to the planar surface 206 of the medical device 205 and can provide a linear compressive force for mounting the medical device to a structure (e.g., IV bar). Additionally, as described above, the opening 307 extends a predetermined distance (x) from the end of the first face 301 and is at a different height (e.g., a height difference "h"), and forms a predetermined angle (θ) with the centerline of the arm of the first face 301 (and the mounting fixture 311), which allows the clamping member 325 to be aligned perpendicularly to the planar surface 206 of the medical device 205. Furthermore, due to the different height of the opening 307 (compared to the centerline of the arm of the mounting fixture 311 and the first face 301), the clamping member 325 generates a torque that stabilizes the medical device 205.
[0034] The hand member 329 allows the user to rotate the clamping mechanism 220 clockwise or counterclockwise to engage or disengage the clamping mechanism 220. Specifically, the hand member 329 is used to align one or more protruding key members 340 with the channels 317 and / or grooves 319 of the clamping body 215. In addition, the hand member 329 acts as a stop to prevent the clamping members 325 from being removed from the clamping body 215.
[0035] Fastener 330 is attached to a first end 327 adjacent to clamp member 325 and provides a first surface for compressing spring element 335. Fastener 330 may be formed on or attached to clamp member 325. Fastener 330 may be a lock nut, bolt, or other type of fastener. Similar to hand member 329, fastener 330 acts as a stop to prevent clamp member 325 from being removed from clamp body 215.
[0036] One or more protruding key members 340 are disposed on the middle portion of the clamping member 325 (e.g., between the first end 327 and the second end (represented by the hand member 329)). The protruding key members 340 may be disposed at predetermined positions on the clamping member 325 based on the structure to which the clamping device 210 is configured for coupling. Example predetermined positions are referenced below. Figure 3D describe.
[0037] The protruding key member 340 may be positioned on one side of the clamping member 325 (e.g., along an axis) and extend perpendicularly to the clamping member 325, and may have a predetermined width and / or predetermined length. The protruding key member 340 operates as one or more keys and is configured to be received by one or more slots 309 and / or channels 317 (each of which may have a width and / or length equal to or greater than the predetermined width and / or predetermined length of the protruding key member 340). More specifically, when one or more protruding key members 340 are aligned with slots 309, the clamping mechanism 220 is capable of traveling through openings 307. According to various embodiments, the protruding key member 340 may be disposed on opposite sides of member 325, thereby being... Figure 3A The dual-slot 309 receiver.
[0038] Additionally, when one or more protruding key members 340 are positioned within the channel 317 (e.g., via alignment of the protruding key members 340 with the slot 309, allowing the clamping member 325 to enter the channel 317) and further aligned with the groove 319, the hand mechanism 329 can rotate such that the protruding key members 340 are positioned within the groove 319, thus locking the position of the clamping mechanism 220. In some embodiments, such as Figure 3D As depicted, multiple protruding key members 340 can be arranged in series along the clamping member 325, spaced apart from each other by a predetermined distance. This allows the clamping mechanism 220 to mount the medical device 205 with structures of different sizes (e.g., IV bars 255 of different diameters). Alternatively, as Figure 3C As shown, the clamping component 325 may include a single set of protruding key components 340 to accommodate a structure of a predetermined size.
[0039] Spring element 335 is disposed on clamping member 325, between fastener 330 and protruding key member 340. When spring element 335 is disposed between fastener 330 and protruding key member 340, spring element 335 is not compressed. See below for reference. Figures 4A-4E As described above, when the clamping mechanism 220 is pulled back, the spring element is compressed between the surface of the fastener 330 and the surface of the opening 307.
[0040] Another example clamping mechanism 350 is similar to clamping mechanism 220. Example clamping mechanism 350 includes two or more sets of protruding key members. Each set of protruding key members can be positioned at a corresponding predetermined location on clamping member 325. For example, a first set of protruding key members 355 can be positioned at a first predetermined location on clamping member 325, a second set of protruding key members 357 at a second predetermined location on clamping member 325, a third set of protruding key members (one or more protruding key members 340) at a third predetermined location on clamping member 325, and a fourth set of protruding key members 359 at a fourth predetermined location on clamping member 325. The third predetermined location on clamping member 325 is associated with an IV bar having a standard diameter (e.g., 18 mm). The fourth predetermined location on clamping member 325 can be used for connection to structures including smaller diameters. The first and second predetermined locations on clamping member 325 can be used for connection to structures having diameters larger than the standard diameter.
[0041] In some embodiments, when the clamping mechanism 220 has two or more sets of protruding key members, the spring element 335 is adjusted to be positioned between the fastener 330 and a specific set of protruding key members (e.g., a first set, a second set, a third set, or a fourth set). As described above, the clamping mechanism 220 may have a single set of protruding key members (e.g., one or more protruding key members 340). When a single set of protruding key members is formed on the clamping mechanism 220, the position of the protruding key member 340 on the clamping member 325 is determined based on the dimensions of the structure to which the clamping device 210 is configured to be coupled.
[0042] Figures 4A-4E A clamping mechanism according to some embodiments is shown, with an opening running through the clamping mechanism. Figure 4A The clamping device 210 at the first time point 410 is shown. Figures 2A-2C ), Figure 4B The clamping device 210 at the second time point 420 is shown. Figure 4C The clamping device 210 is shown at the third time point 430. Figure 4D The clamping device 210 at the fourth time point 440 is shown, and Figure 4EThe clamping device 210 is shown at the fifth time point 450.
[0043] At the first time point 410, the clamping device 210 is in a pre-engaged position (e.g., the clamping mechanism 220 is pulled back). The spring element 335 is compressed between the fastener 330 and the opening 307 of the clamping body 215 (e.g., an opening on the opposite surface of the clamping body 215). The spring element 335 cannot freely traverse the opening 307. The spring element 335 is compressed such that it has the following characteristics: Figure 2B The compression length is shown. When the spring element 335 has the compression length, a structure (e.g., IV bar) can be positioned between the clamping member 325 of the clamping mechanism 210 and the medical device 205, such that when the spring element 335 extends, a compressive force is applied to the structure, thereby coupling the medical device 205 to the structure. Figure 4A As further shown, at the first time point 410, one or more protruding key members 340 of the clamping member 325 are aligned with one or more slots 309 of the opening 307, and one or more protruding key members 340 are pulled back to the outside of the opening 307.
[0044] At the second time point 420, the clamping member 325 is released and begins to move within the opening 307 via the channel 317. Specifically, one or more protruding key members 340 are received by the slot 309 and traverse the channel 317, allowing the clamping member 325 to traverse the opening 307. At the second time point 420, the spring element 335 begins to partially elongate (attempting to return to its free or uncompressed length). The clamping member 325 (automatically) traverses the opening 307 until its first end contacts a structure (e.g., an IV bar). Alternatively, if the structure is absent (e.g., between the medical device 205 and the clamping member 325), the clamping member 325 traverses the opening until the spring element 335 reaches its free length. In other words, the spring element 335 automatically actuates the clamping member 325, leaving the spring element in its resting (uncompressed) state.
[0045] At a third time point 430, one or more protruding key members 340 are located within the channel 317 and aligned with the groove 319. In some embodiments, the groove 319 is located at a predetermined position along the opening 307 such that the clamping member 325 contacts the structure, and sufficient compressive force (e.g., a compressive force capable of supporting at least 9.5 kg) is applied to the structure and the medical device 205. For example, the structure (such as the IV bar) may be of standard diameter (18 mm), and the groove 319 may be provided within the opening 307 such that the clamping member 325 contacts the IV bar and applies sufficient force thereto. As described above, the spring element 335 may be selected such that the force applied by the spring supports a predetermined weight.
[0046] When the clamping device 210 is in the engaged position, one or more protruding key members 340 of the clamping member 325 are aligned with the groove 319, and the clamping mechanism 220 applies a (compressive) force to the structure, which holds the medical device 205 ( Figures 2A-2C The clamping device 205 is connected to the structure. The force applied to the structure is constant and based on the spring stiffness of the spring element 335. In other words, the spring structure 335 can partially extend when the protruding key member 340 of the clamping member 325 is aligned with the groove 319; however, the structure between the medical device 205 and the clamping member 325 restricts the extension of the spring structure 335, and the spring structure 335 applies a force to the structure based on the restricted extension and the spring stiffness of the spring structure 335. Thus, each time the medical device 205 is coupled to the structure via the clamping device 210, the clamping device 210 applies the same (compressive) force (e.g., the spring structure 335 presses down on the structure). The spring structure 335 of the clamping device 210 prevents user error by preventing the clamping device from being over-tightened (which could damage the structure or make it difficult for the medical device 205 to disengage from the structure) or under-tightened (which could cause the medical device 205 to slip or accidentally disengage from the structure).
[0047] At the fourth time point 440, the user rotates the hand member 329 so that one or more protruding key members 340 are received via the groove 319. The hand member 329 can rotate clockwise or counterclockwise. By rotating the hand member 329 clockwise or counterclockwise while aligning the protruding key members 340 with the groove 319, the position of the clamping member 325 is locked (e.g., it cannot be pulled back, thereby reducing the compressive force, or pushed inward, thereby increasing the compressive force).
[0048] At the fifth time point 450, one or more protruding key members 340 are positioned within the groove 319. When one or more protruding key members 340 are positioned within the groove 319, the clamping mechanism 220 is locked, preventing the clamping device 210 from being accidentally released. In this way, the medical device 205 will not accidentally disengage from the structure, or the force applied to the structure will not decrease over time.
[0049] To disengage the medical device 205 from the structure, the user can rotate the hand member 329 to align one or more protruding key members 340 with the channels 317 and slots 309, and pull back the clamping mechanism 220. After the force applied to the structure by the clamping mechanism 220 (or clamping member 325) is removed, the structure can be removed from the clamping device 210 and / or the medical device 205.
[0050] Figure 5This is a flowchart illustrating a method for forming a clamping device according to some embodiments. Methods consistent with this disclosure may include at least some, but not all, of the operations shown in method 500 and / or operations performed in a different order. Furthermore, methods consistent with this disclosure may include at least two or more steps, such as the steps in method 500 that overlap in time or are performed almost simultaneously.
[0051] Method 500 includes providing (510) a clamp body. The clamp body includes (515) an opening including a slot through at least a portion of an inner wall of the opening. The slot is configured to prevent the clamp member from passing through the opening when a clamp member passes through the opening and a protruding key member of the clamp member is not aligned with the slot. For example, as referenced above... Figures 3A-4E The slot 309 is configured to receive one or more protruding key members 340 of the clamping mechanism 220 to allow the clamping mechanism 220 to pass through the opening 307.
[0052] Method 500 further includes providing (520) a clamping mechanism. The clamping mechanism includes (521) a clamping member extending through an opening. The clamping mechanism includes (523) a fastener engaged on a first side of the opening to a first portion of the clamping member, adjacent to a first end of the clamping member. For example, as... Figures 3A-4E As shown, fastener 330 is adjacent to the first end of clamping member 325 on the first side of opening 307, such that fastener 330 operates as a stop (e.g., to prevent clamping member 325 from being removed from clamping mechanism 220). The clamping mechanism includes (525) a hand member coupled to a second end of the clamping member, opposite the first side of the opening and opposite the first end. For example, as... Figures 3A-4E As shown, the hand member 329 is adjacent to the second end of the clamping member 325 on the second side (opposite to the first side) of the opening 307, such that the hand member 329 operates as a stop (e.g., to prevent the clamping member 325 from being removed from the clamping mechanism 220). The clamping mechanism includes (527) a protruding key member that extends from the second portion of the clamping member and is configured to be received via a slot. The second portion is located at the middle portion of the clamping member, between the first end and the second end of the clamping member. The clamping mechanism further includes (529) a spring element disposed on the clamping member between the fastener and the first side of the opening, such that when the position of the clamping member changes, the spring element is compressed or extended between the fastener and the first side of the opening. For example, when the clamping mechanism 210 is in the pre-engaged position 230 ( Figure 2B For example, when the clamping member 325 is pulled back or retracted, the spring element 335 is compressed between the fastener 330 and the first side of the opening 307, such that the spring element 335 is in its compressed length. When the clamping mechanism 210 is in the engaged position 250 ( Figure 2C When the spring element 335 partially elongates between the fastener 330 and the first side of the opening 307, the spring element 335 attempts to return to its free length (e.g., Figure 2A As shown above, a compressive force is applied to the structure between the medical device 205 and the clamping element 325, thereby coupling the medical device 205 to the structure. An additional example of the clamping mechanism 220 is referenced above. Figures 3A-4E It has been described.
[0053] Method 500 further includes connecting the fixture body to the fixture mechanism (530).
