Orthopedic patient positioner apparatus, system, and method for hip arthroplasty

An anterior support assembly, configured to couple to a support table for surgery of a patient disposed in the lateral decubitus position, the anterior support assembly comprising:

• an anterior base configured to couple to, and slidably adjust with respect to, the support table, the anterior base comprising a two or more anterior base slots including:
• a first anterior base slot disposed along a lateral direction, and
• a second anterior base slot disposed in a second direction, offset from the lateral direction and defining an angle α,
• each anterior base slot having a lock pin ramp portion, a lock pin traversing portion, and a slot opening;
• an anterior tower comprising a rail configured to couple to a slot of the plurality of slots, and a lock pin assembly including:
• a lock pin configured to move freely relative to the anterior tower, and
• a biasing element configured to bias the lock pin outwardly when the lock pin is unobstructed to define a first position;
• and
• one or more adjustable pads configured to couple to the anterior tower, the one or more adjustable pads configured to couple to the patient,
• wherein, when being assembled, the rail of the anterior tower couples to a slot of the plurality of slots, such that the lock pin moves along the lock pin ramp portion, and the lock pin ramp portion automatically moves the lock pin inwardly relative to the anterior tower to a second position while the lock pin advances along the lock pin traversing portion, and then the lock pin moves back to the first position upon entering the slot opening, to fixedly couple the anterior tower to the anterior base.

A surgical patient positioner comprising:

• a base plate configured to couple to a surgical support table, the base plate comprising:
• an upper surface including:
• a plurality of anterior tracks configured to slidably couple to an anterior support assembly, and a plurality of posterior tracks configured to slidably couple to a posterior support assembly;
• and
• a lower surface including one or more base plate slots configured to receive an extension bar;
• one or more base plate openings extending through the base plate from the upper surface to the lower surface, each of the one or more base plate openings being configured to receive a drop bar;
• and
• at least one contoured portion adapted to fit the base plate in between the pelvis and rib cage when a patient is disposed thereon;
• each drop bar comprising a drop bar head disposed at an end of a drop bar body, such that in an assembled configuration the drop bar body passes through the base plate opening and the drop bar head inhibits further movement of the drop bar therethrough;
• one or more clamps adapted to couple the drop bar body to a rail of the surgical support table;
• the anterior support assembly comprising:
• an anterior base configured to couple to, and slidably adjust with respect to, the base plate, the anterior base comprising a plurality of anterior base rails, each anterior base rail being configured to couple to an anterior track, the anterior base further comprising two or more anterior base slots including:
• a first anterior base slot disposed along a lateral direction, and
• a second anterior base slot disposed in a second direction that is offset from the first direction defining an angle α,
• each anterior base slot having a lock pin ramp portion, a lock pin traversing portion, and a slot opening, and
• an anterior tower comprising an anterior tower rail configured to couple to one of the anterior base slots, and a lock pin assembly including:
• a lock pin configured to move freely relative to the anterior tower, and
• a biasing element configured to bias the lock pin outwardly when the lock pin is unobstructed to define a first position,
• one or more adjustable pads configured to couple to the anterior tower, the one or more adjustable pads configured to couple to the iliac crest of a patient,
• wherein, when being assembled, the anterior tower rail couples to an anterior base slot, such that the lock pin moves along the lock pin ramp portion, and the lock pin ramp portion automatically moves the lock pin inwardly relative to the anterior tower to a second position while the lock pin advances along the lock pin traversing portion, and then the lock pin moves back to the first position upon entering the slot opening, to fixedly couple the anterior tower to the anterior base,
• the posterior support assembly comprising:
• a posterior base configured to couple to, and slidably adjust with respect to, the base plate, the posterior base comprising at least one posterior base rail that is configured to couple to a posterior track, the posterior base further comprising at least one posterior base slot;
• one or more posterior towers including a posterior tower rail configured to slidably couple to one of the posterior base slots;
• and
• a posterior support plate configured to couple to the one or more posterior towers, the posterior support plate being suitably configured to couple to the lumbar region of the patient.
