Abstract: An orthopaedic surgical instrument includes a customized patient-specific 5-in-1 cutting block having a plurality of ribs and cutting guide slots extending between each rib. A bone-facing surface of each rib has a customized patient-specific negative contour configured to receive a portion of a corresponding positive contour of the patient's femur.

Abstract: An orthopaedic surgical instrument is provided having a first customized patient-specific surgical instrument and a second customized patient-specific surgical instrument configured to be removably coupled to the first customized patient-specific surgical instrument. The second customized patient-specific surgical instrument includes a body positioned in a gap defined between posteriorly-extending arms of the first customized patient-specific surgical instrument.

Abstract: An orthopaedic surgical instrument includes a customized patient-specific surgical instrument having a body. The body has a bone-facing surface and an outer surface positioned opposite the bone-facing surface. The body includes a number of bone-contacting segments raised relative to the bone-facing surface. The bone-contacting segment include negative contours shaped to match corresponding positive contours of a patient's bone. The positive contours correspond to silhouette curves of a three-dimensional model of the patient's bone that correspond to contours of the patient's bone captured in images used to generate the model. The body further includes a number of surgical guides extending from the outer surface to the bone-contacting surface or the bone-facing surfaces. A method associated with the instrument is also disclosed.

Abstract: A customized patient-specific orthopaedic instrument for facilitating implantation of an acetabular cup prosthesis in a coxal bone of a patient and method of use is disclosed. The customized patient-specific orthopaedic instrument includes a customized patient-specific acetabular guide. The customized patient-specific acetabular guide includes a longitudinal passageway for an acetabular reamer and/or an impactor and a plurality of arms with attached mounting pads. Each pad of the guide is positioned relative to the body based on the contours of the coxal bone of the patient and a predetermined degree of anteversion and inclination angles of the acetabular cup prosthesis when implanted in the patient's coxal bone.

Abstract: A pipe laying machine is disclosed. The example pipe laying machine includes a platform configured to move continuously relative to the ground and a pipe connector section configured to slide along a portion of length of the platform relative to the platform. The pipe connector section includes an upstream stopper and a downstream pipe connector section configured to slide along a portion of a length of the pipe connector section relative to the pipe connector section. The upstream stopper is configured to prevent a bell mouth of a bell end of an upstream pipe from passing through. The downstream pipe connector section includes a downstream clamp, which is configured to grip a spigot end of a downstream pipe. The downstream pipe connector section is configured to slide toward the upstream pipe to connect the upstream pipe with the downstream pipe.

Abstract: An irrigation pipe laying machine for glued or gasketed piped is disclosed. The example pipe laying machine includes a platform including a first end and a second end. The pipe laying machine also includes a clamp configured to grip a portion of a bell end of an upstream pipe to prevent the upstream pipe from moving, a spigot end of the upstream pipe being connected to a second upstream pipe. The pipe laying machine further includes a plunger located adjacent to the second end of the platform and configured to push against a bell end of a downstream pipe causing a spigot end of the downstream pipe to connect to the bell end of the upstream pipe. The plunger is configured to push against the face of the bell end of the downstream pipe when the clamp grips the portion of the bell end of the upstream pipe.
