A system can form a pilot hole to secure a securable element, such as an acetabular cup. A saddle can removably attach to the securable element. The saddle can confine a translator and allow the translator to move along a translator axis between a first translator position and a second translator position. A punch element can be movably coupled to the saddle and the translator such that when the saddle is removably attached to the securable element, moving the translator from the first translator position toward the second translator position can advance a tip of the punch element from the saddle through the securable element along a punch axis that is angled with respect to the translator axis. An impaction stem can be coupled to the translator by a joint, such as a ball-and-socket joint, and can impart motion to the translator.

Forming a pilot hole

Described herein are examples of orthopedic reamer heads for preparing a bone to receive an implant, as well as methods of assembling reamer heads. An illustrative example of a modular reamer head can include a body and a cutting system. The body can include a generally dome shape having an outer surface extending from an apex region to a base. The outer surface can have a recess including one or more arcuate channels that extend from the apex region towards the base of the dome. The cutting system can have one or more arcuate elements having cutting elements. One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.

Described herein are examples of adjustable orthopedic reamer heads and methods for preparing a bone to receive an implant. The adjustable reamer heads and methods can include changing a cutting characteristic such as the size of an adjustable reamer head. In an illustrative example of an adjustable reamer head, the reamer head can include a housing, an actuator and a plurality of cutting elements. The plurality of cutting elements can be retained by the housing and can be operably coupled to the actuator. The plurality of cutting elements can include a first size cutting element and a second size cutting element. When the actuator is actuated, the first size cutting element and the second size cutting element can move relative to one another to change from a first cutting size to a second cutting size.

Adjustable acetabular reamers and methods

Illustrative methods of manufacturing flexible drive shaft assemblies for preparing bone can include steps such as providing, receiving or manufacturing a mold. Injecting a first polymeric material into the mold to form a coupling member, the coupling member adapted for attachment to a torque-providing driving tool. Injecting a second polymeric material into the mold to form a work member, the work member adapted to interface with the bone to prepare the bone. The method can further include injecting a third polymeric material into the mold in an overmolding process to form a flexible shaft extending from the coupling member to the work member. The assemblies resulting from such methods can include a flexible shaft that is adapted to transmit a majority of a torque received from a torque-providing driving tool through the flexible shaft. In some examples, the flexible shaft can include a solid polymeric shaft.

Flexible drive shaft assembly and methods

A tool body having a first clamp element positioned on a first tool arm and a drill guide positioned on a second tool arm. The surgical tool can also have a slider element slidable on the tool body, the slider element having a depth probe and a second clamp element. The second clamp element can be engaged with the first clamp element such that the first and second elements cooperate to define a clamp opening for receiving a supplemental screw.

Disposable surgical tool

A ratcheting driver can be configured to selectively transmit a torque to a fastener. The driver can include a handle, a geared body, and a shaft. The handle can include a housing, a pawl, and a biasing element. The housing can include a central bore and a shaft bore extending through a distal portion of the housing. The pawl can extend radially inward from the housing into the central bore. The biasing element can engage the housing. The geared body can be rotatably engageable with the pawl to allow rotation of the geared body relative to the handle in a first direction and to limit rotation of the geared body relative to the handle in a second direction, where the biasing element can be engageable with the geared body to bias the geared body distally.
