This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/698,176 Filed Sep. 7, 2012, which is expressly incorporated by reference herein.
The present disclosure is related to a support apparatus for supporting a patient. More particularly, the present disclosure relates to a support apparatus including a surgical table and a limb support coupled to the surgical table.
Often, when a patient is sedated for a surgery, the patient is supported by and secured to braces or supports coupled to a surgical table. Sometimes, unique supports are provided for a patient's extremities such as arm boards, leg supports, hand boards, stirrups, and boots.
Supports known in the art sometimes secure patients to resist patient movement. Such supports can sometimes allow excessive patient movement relative to the supports. The position and orientation of supports is often adjusted during surgery to improve access to a surgical site or to move portions of the patient's body such as bones, muscles, tendons, and ligaments to evaluate the surgical results.
The present application discloses one or more of the features recited in the appended claims and/or the following features which, alone or in any combination, may comprise patentable subject matter:
According to a first aspect of the present disclosure, a limb support comprises a longitudinal member configured to be coupled to a patient support apparatus, and a carriage movable along the longitudinal member to a plurality of positions. The carriage includes a plurality of rollers supporting the carriage relative to the longitudinal member for movement along the longitudinal member. The carriage also includes a clamp for securing the carriage to the longitudinal member. The clamp includes a plurality of elastomeric blocks which deform under a load to secure the carriage to the longitudinal member.
In some embodiments, at least one elastomeric block is deformed by a cam. In some embodiments, the carriage includes a housing, and the at least one elastomeric block is supported on a plate that is pivotably coupled to the housing.
In some embodiments, the carriage includes an actuator that is movable between a first position wherein the at least one elastomeric block is subjected to a first load and a second position wherein the at least one elastomeric block is subjected to a second load. In the first position, the elastomeric block permits relative movement between the at least one elastomeric block in the longitudinal member. In the second position, the second load deforms the elastomeric block sufficiently to prevent movement between the at least one elastomeric block and the longitudinal member under normal operating conditions.
In some embodiments, at least one of the plurality of rollers includes a guide surface that engages a portion of the longitudinal member to prevent lateral movement of the carriage relative to the longitudinal member. The longitudinal member may include an upper surface and a lower surface. The plurality of rollers may include a first roller supporting the carriage relative to the upper surface of the longitudinal member and a second roller supporting the carriage relative to the lower surface of the longitudinal member.
In some embodiments, the longitudinal member further includes first and second lateral surfaces and wherein the first and second rollers are formed to include surfaces that engage the first and second lateral surfaces of the longitudinal member.
In some embodiments, the at least one of the plurality of rollers includes a tread configured to resist rolling to dampen movement of the carriage along the longitudinal member.
According to another aspect of the present disclosure, a carriage for a limb support comprises a space for receiving a longitudinal member of a patient support apparatus, a plurality of rollers configured to engage the longitudinal member and a locking mechanism. The plurality of rollers is configured to maintain alignment of the carriage during movement of the carriage along the longitudinal member. The locking mechanism is configured to secure the carriage to the longitudinal member at any of an infinite number of positions along the length of the longitudinal member, the locking mechanism being lockable with a single action.
In some embodiments, the locking mechanism includes a cam acting on a deformable block to engage the deformable block with the longitudinal member to secure the carriage to the longitudinal member.
In some embodiments, the carriage further comprises a housing defining the space. The locking mechanism may include a plate pivotably coupled to the housing, a deformable block positioned between the plate in the space, the deformable block configured to engage the longitudinal member, a cam supported by the housing, and an actuator. The cam may be configured to engage the plate to cause the plate to pivot between an unlocked position and a locked position. The actuator may be movable between a first position wherein the locking mechanism is unlocked and a second position wherein the locking mechanism is locked.
According to another aspect of the present disclosure, a carriage for a limb support comprises a housing defining a space for receiving a longitudinal member of a patient support apparatus, a plurality of rollers supported from the housing. The plurality of rollers is configured to engage the longitudinal member of the patient support apparatus for movement of the carriage relative to the longitudinal member. The carriage also comprises means for resisting rotation of at least one of the rollers relative to the longitudinal member to dampen the movement of the carriage relative to the longitudinal member.
In some embodiments, the means for resisting rotation includes elastomeric material that engages at least one surface of the longitudinal member to resist movement relative to the longitudinal member.
In some embodiments, the means for resisting rotation includes an annular member supported on a roller, the annular member deformable under a load to resist rotation of the roller relative to the longitudinal member.
In some embodiments, the means for resisting rotation includes an elastomeric block that is deformable under a load, the elastomeric block configured to engage at least one surface of the longitudinal member to limit movement between the carriage and the longitudinal member.
Additional features, which alone or in combination with any other feature(s), including those listed above and those listed in the claims, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the invention as presently perceived.
The detailed description particularly refers to the accompanying figures in which:
A support apparatus 10 includes, for example, a surgical table 12 and a limb-support unit 14 as shown in
Limb-support unit 14 includes a countertraction unit 18, a single-axis leg holder 20, and a two-axis leg holder 22 as shown in
The two-axis leg holder 22 includes a joint mount 24, a multi-axis joint 26, and a spar 28, as shown in

Referring now to
The roller 38 includes an axle 90 received at one end into a cavity 92 in cover 66 and into a cavity 94 in cover 68 at the opposite end of the axle 90. The roller body 70 is supported on the axle 90 by two bearings 96 and 98 such that the roller 38 rotates about the axle 90 when the carriage 32 is moved along the spar 28. The rollers 34 and 36 are supported in a similar manner from the covers 66 and 68. Because the rollers 34 and 36 are positioned below the spar 28, the outer surface 88 of the rollers 34 and 36 engage the lower surface 86 of the spar 28 as the carriage is moved along the spar 28.
The fourth roller 40 is different from the rollers 34, 36, and 38 in that roller 40 is configured to provide some resistance during movement of the carriage 32 along the spar 28. The need for rolling resistance of the carriage is created by the potential for the two-axis leg holder 22 to be rotated about an axis 140 shown in
Referring again now to
Referring now to
In use, a user will secure the foot of a patient into the surgical boot 30, adjust the position of the two-axis leg holder 22 or the single-axis leg holder 20, position the carriage 32 in the correct location along the spar 28 and move the locking mechanism 110 to the locked position, and further adjust the position of the patient's foot using adjustments available on the coupler 42. The carriage 32 provides the benefit of allowing the position of the foot support 58 to be positioned in an infinite number of positions along the length of the spar 28 and to be locked into position with a single action to position locking mechanism 110.
Although certain illustrative embodiments have been described in detail above, variations and modifications exist within the scope and spirit of this disclosure as described and as defined in the following claims.
This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/698,176, filed Sep. 7, 2012 which is hereby expressly incorporated by reference herein.
