Abstract

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.
