Definitions
- the present disclosure relates to clamps that attach to rails, and particularly to clamps that attach to accessory rails of surgical tables to support accessories used during surgical procedures. More particularly, the present disclosure relates to rail clamps having movable jaws that permit the clamps to couple to accessory rails without having to slide the clamp onto the rail from an end of the rail. Accessory rail clamps to attach accessories, such as leg stirrups and arm boards, to accessory rails of surgical tables are known. See, for example, U.S. Pat. No. 6,622,980.
- accessory rails of surgical tables are typically made of metal, such as stainless steel, and because it is desirable for tables used in orthopedic procedures to be substantially radiolucent so that x-ray images and fluoroscopic images of patients may be taken during surgical procedures, most Jackson tables do not have standard-size accessory rails.
- the present invention comprises a clamp having one or more of the features listed in the appended claims, or one or more of following features or combinations thereof, which alone or in any combination may comprise patentable subject matter:
- a clamp is provided for securing an accessory, such as a head support apparatus, to a rail of a patient support apparatus, such as a spinal surgery extension.
- the clamp may comprise a first or fixed jaw adapted to be placed on the rail, a second or movable j aw coupled to the first j aw for movement between an open position and a closed position, a resilient member that is forced against the rail when the second jaw is moved to the closed position to inhibit the movement of the clamp along the rail, and a latch coupled to the second jaw and movable relative to the second jaw between a latched position in which the second jaw is latched in the closed position relative to the first jaw and an unlatched position in which the second jaw is movable between the open and closed positions.
- the first jaw is integrally formed with an associated accessory.
- the first jaw may have an aperture in which the resilient member is received.
- the first jaw may be configured to hook onto a first portion of the rail and the second jaw may be configured to hook onto a second portion of the rail when in the closed position.
- the second jaw may be coupled to the first jaw for pivoting movement about an axis that is generally parallel to the rail.
- the latch may be coupled to the second jaw for pivoting movement about an axis that is generally parallel to the rail.
- the latch may be biased toward the latched position by a spring.
- the spring may be received in an aperture in the second jaw.
- the latch may have a protruding portion and the first jaw may have a recess in which the protruding portion of the latch is received when the second jaw is in the closed position and the latch is in the latched position.
- the first jaw, the second jaw, the resilient member, and the latch are each made from a radiolucent material.
- the clamp may further comprise a disk that is secured to the resilient member and that is made from a material that is harder than the resilient member.
- the second jaw may contact the disk when moving from the first position to the second position.
- the resilient member may be received in an aperture in the second jaw and at least a portion of the disk may be situated outside the aperture on one side of the first jaw. At least portion of the resilient member may be situated outside the aperture on an opposite side of the first jaw.
- the aperture and the resilient member may each have a stepped configuration to prevent the resilient member and disk from falling out of the aperture in a first direction.
- a portion of the second jaw may overlap the disk to prevent the resilient member and jaw from falling out of the aperture in a second direction.
- the rail to which the clamp couples may be quadrilateral in cross section having a top, bottom, and opposite sides.
- the first jaw may be configured to overlap at least a portion of the top and opposite sides of the rail and the second jaw may be configured to overlap at least a portion of the top, the bottom, and one of the sides of the rail when in the second position.
- the latch may be coupled to the first jaw so as to pivot downwardly when moving form the latched position to the unlatched position and the first jaw may be coupled to the second jaw so as to pivot upwardly when pivoting between the second position and the first position.
- the second jaw may have a cutout in which at least a portion of the latch is received.
- the second jaw may have an arm on each side of the cutout and the latch may be coupled to the second jaw by a pivot pin having end regions received in bores formed in each of the arms of the second jaw and having a middle region received in a bore formed in the latch.
- the first jaw may have a protrusion that substantially fills at least a portion of the cutout when the second jaw is in the second position.
- the second jaw may have an arm on each side of the cutout and the second jaw is coupled to the first jaw by a pivot pin having end regions received in bores formed in each of the arms of the second jaw and having a middle region received in a bore formed in the protrusion of the first jaw.

- the seat portions 264 of the friction buttons 240, 242 are configured to engage the seat portions 274 of the openings 248, 250 to prevent the friction buttons 240, 242 from falling downwardly through the openings 248, 250 when the friction buttons 240, 242 are not supported by the associated rail 70, 72 and the clamp 120 is the orientation shown in Figs. 3 and 4.
- the step portions 192, 194 of the second jaw 124 in the regions adjacent pin 220 prevent the friction buttons 240, 242 from falling out of the openings 248, 250 when the clamp 120 is turned upside down.
- the friction buttons 240, 242 and the associated discs 244, 246 are dimensioned such that, when the friction buttons 240, 242 are supported by the associated rail 70, 72, the friction buttons 240, 242 protrude below the downwardly- facing surfaces of the bight portion 156 of the first jaw 122 as shown in Fig. 3, so that as the second jaw 124 pivots from the open position (Fig. 3) to the closed position (Fig. 4), the step portions 192, 194 of the second jaw 124 press down on the discs
- the friction buttons 240, 242 to press down on the associated rail 70, 72 (Fig. 4) to inhibit movement of the clamp 120 along the associated rail 70, 72.
- the discs 244, 246 and the head portions of the friction buttons 240, 242 have the same diameter.
- the friction buttons 240, 242, the associated discs 244, 246, and the pivotable jaw 124 cooperate to form a lock mechanism for inhibiting movement of the clamp 120 along the associated rail 70, 72 when jaw 124 is in the closed position.
- the finger latch 128 is coupled to the second jaw 124 for pivoting movement about a longitudinally-extending pivot pin 280 between a first or latched position, shown in Fig. 5, and a second or unlatched position, shown in Fig. 6.
- the pivot pin 280 extends through a bore 282 in the ledge portion 212 of the second jaw 124, through a bore 284 in the latch 128, and through a bore 286 in the ledge portion 214 of the second jaw 124.
- the bores 282, 284, 286 are coaxially aligned with the pivot pin 280.
- set screws 288 are threaded into the openings 282, 286 in the ledge portions 212, 214 so that outer surfaces of the set screws 288 are flush with outer surfaces of the respective ledge portions 212, 214 of the second jaw 124.
- Set screws 288 retain pin 280 in bores 282, 284, 286.
- the inwardly-extending lower arm portion 184 of the second jaw 124 has a step portion 290 that extends upwardly into the cutout 200 in the bight portion 186 of the second jaw 124.
- An outer portion 292 of the step portion 290 has a first width and an inner portion 294 of the step portion 290 has a second width that is less than the first width.
- the latch 128 has a body portion 300, a pair of longitudinally-spaced leg portions 302 that extend downwardly from the body portion 300, a finger grip portion 304 that extends forwardly from the body portion 300, and a protruding portion 306 that extends upwardly from the body portion 300.
- the protruding portion 306 has an outwardly-facing surface 308 and an inwardly- facing surface 310.
- the downwardly- facing surface 166 of the step portion 160 of the first jaw 122 engages the inwardly-facing surface 310 of the protruding portion 306 of the latch 128 to initially cause the latch 128 to pivot downwardly.
- the spring 320 causes the latch 128 to move upwardly so that a tip 312 of the protruding portion 306 of the latch 128 is received in the recess 168 (Fig. 6) in the downwardly-facing surface 166 of the step portion 160 of the first jaw 122 with the inwardly-facing surface 169 (Fig.
- clamps 120 attach to and detach from rails 70, 72 in a quick and easy manner.
- jaw 122 is placed on the one of rails 70, 72 and then jaw 124 is pivoted downwardly from the opened position to the closed position.
- resilient members 240, 242 are automatically forced against the rail 70, 72 to prevent the clamp 120 from moving along the rail and latch 128 automatically snaps into its locked position to retain jaw 124 in the closed position.
- latch 128 is pivoted to its unlatched position and jaw 124 is pivoted upwardly to its open position.
- a user may move latch 128 downwardly to its unlatched position by pressing downwardly on portion 304 of latch 128 with his or her thumb and the user may move jaw 124 to its open position by pulling upwardly on portion 216 of jaw 124 with his or her fingers.
