Disclosed is a leg positioner apparatus to secure placement of a leg in total hip arthroplasty procedures. The leg positioner apparatus can attach to a standard operating table and helps in positioning the operative leg for femoral preparation. The leg positioner apparatus includes a post assembly mounted to an attachment bracket. The attachment bracket can be attached to the operating table. The operative leg can rest on the post assembly during the surgical procedure.

An apparatus for positioning a lower limb of a patient during surgery comprises at least one support structure connectable, through a proximal end, to a support device for a patient and defining a traction axis of the patient's lower limb, a traction slide slidingly movable on the support structure, a gripping body for a distal end of the patient's lower limb connectable to the traction slide. The support structure, when connected to the support device for a patient, is suspended and comprises at least one actuator, hydraulically connected with the traction slide, for moving the support structure in space.

A medical support arm may include a holding end, a coupling end, a coupling-end pivot joint for swiveling the support arm about a pivot axis (A1) and tilting the support arm about a tilt axis (A2), and a clamping mechanism with which the pivot joint can be locked or released as desired. The pivot joint allows the support arm to rotate exclusively about the tilt axis (A2) and the pivot axis (A1). A tilting device may have a tilting element and a cylindrical sliding surface on which the tilting element is seated. A pivot mechanism can have a guide ring and at least one ring guide surface that receives the guide ring. A tilting element, as part of the clamping mechanism, may be provided as a gripper clamp that secures both the tilting device and the pivot mechanism against rotation by clamping the central body.

A surgical boot system and sleeve accessory for hip distraction. The surgical boot system includes an L-shaped rigid shell having a proximal portion and a distal portion. A soft liner is attached to the rigid shell and extends along at least one of the proximal portion and the distal portion. The surgical boot system also includes at least one strap assembly (which can be a plurality of strap assemblies) extending around the rigid shell. A load transmission hoop is connected to and extends around the distal portion of the rigid shell and an attachment point is connected to the load transmission hoop. The rigid shell is pivotable about the attachment point. Specifically, the attachment point is configured to interface with a hip distractor apparatus in a way that allows for multiple degrees of freedom.

A method for hip distraction includes positioning a patient on a slide-resisting pad placed on a surgical table; tilting the surgical table so that the patient is in a first degree of inclination; applying a distraction force to a leg of the patient while the patient is in the first degree of inclination so that a hip joint of the patient is distracted, wherein the distraction force is opposed by a combination of a slide-resisting friction force provided by the slide-resisting pad and a gravitational force attributable to the first degree of inclination; reducing the tilt of the surgical table in accordance with a reduction of the distraction force over time so that the patient is in a second degree of inclination; and performing at least a portion of a surgical procedure on the distracted hip joint while the patient is in the second degree of inclination.

Embodiments disclosed herein concern a distraction system for use with a surgical table having a table portion and a base portion. The distraction system includes a pair of arms rotatably connectable to the base portion at a proximal end portion of each arm. A pair of telescopically adjustable support posts extend upwardly from corresponding arms. Each arm rotates about a vertically oriented axis to provide for hip adduction and abduction of a patient's leg. Each support post extends from a linear bearing attacked to the corresponding one of the pair of arms for movement along the arm to facilitate applying traction to a patient's leg. The system can also include a table extension attachable to the table portion and a friction pad mounted on the table extension.

Method of securing a patient onto an operating or surgical table when the patient is in a position for a hip procedure and apparatus therefor including a kit. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. § 1.72(b). As stated in 37 C.F.R. § 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used f or interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

In general, various surgical patient positioners and methods for using the same are provided. For example, a surgical patient support is provided for use during anterior hip replacement surgery. The surgical patient support can have a body support configured to receive an upper body of a patient thereon and one or more extremity supports configured to receive one or more patient extremities thereon.

A patient limb positioning apparatus comprises a movement assembly operating on a coupling bracket which can be engaged with the patient's limb, to move the limb according to a plurality of axes of movement. The movement assembly comprises, for at least one of said axes of movement, a drive unit which can be activated to move the coupling bracket according to a predetermined direction of movement. A load transducer detects a load transmitted between the coupling bracket and the drive unit in the respective direction of movement, to emit a signal representative of a detected load value. An electronic control unit is selectively switchable to a load control command mode and is suitable to cyclically compare the measured load value with a pre-set load value, to control activation of the drive unit when the detected load value differs from the pre-set load value.
