Abstract: A coupling mechanism designed to removably attach a reamer to the distal end of a spindle or shaft is disclosed. The coupling comprises a collar having an annular sidewall that defines a collar throughbore, the collar annular sidewall comprising a plurality of spaced part first slots that at least partially extend through the sidewall and a shank disposed within the collar throughbore. The shank is constructed with a shank annular sidewall in which a plurality of spaced apart second slots at least partially extend therethrough. A bias member that provides a bias force in a distal direction that acts on the collar is incorporated within the mechanism. The collar is capable of sliding in an axial direction such that the first and second slots become aligned to secure the cross bar of a reamer therein.

Abstract: A retractor system, kit and method of use includes a plurality of retractors for use in retracting a wound during a minimally-invasive hip replacement surgery to define an access space to a surgical site is discussed. Each of the retractors comprises a handle portion configured to be held by a user, a curved bend portion distal of the handle portion, and a wound contact portion attached to the curved bend portion. The wound contact portion is configured to contact tissue of the wound when at least a portion of the retractor is inserted through a skin incision that defines the wound. Each retractor also has a distal portion disposed distally of the wound contact portion, wherein the wound contact portion has a generally curved cross-sectional profile perpendicular to its length that is configured to prevent necrosis of the tissue during retraction. In addition, the cross-sectional profile provides an improved line of sight during the surgical procedure. Furthermore, the cross-sectional profile prevents the jamming of a cutting device, such as a reamer inserted through the incision, while the retractors retract the wound.

Abstract: An orthopedic impactor device for positioning an orthopedic prosthetic cup implant during a hip replacement surgery is described. The impactor comprises a distal prosthetic cup engagement portion which is separated from a proximal strike plate by an elongated housing and handle. The housing has a length that extends from a proximal housing portion to a distal housing end with an intermediate housing section therebetween. The intermediate housing section comprises spaced right and left side walls that extend upwardly from a bottom wall to an upper opening. A drive train, comprising a connection rod connectable to an orthopedic prosthetic cup, at least partially resides within the elongated housing. The drive train comprises a linkage sub-assembly that transfers rotational movement of a shaft located at the drive shaft proximal end to the connection rod.
