Surgical instrument with an articulating shaft locking mechanism

A surgical instrument particularly suited to endoscopic use articulates an end effector by including a laterally sliding member in a proximal portion of a shaft that pivots the end effector to a selected side. Differentially opposing actuating forces (e.g., hydraulic, fluidic, mechanical) act against the laterally sliding member without binding by incorporating guidance mechanisms between the laterally sliding member and a frame of the shaft. A locking member advantageously unlocks automatically as articulation is commanded by resists backdriving of the mechanism.

Polyaxial pedicle screw having a threaded and tapered compression locking mechanism

A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

Locking handle deployment mechanism for medical device and method

InactiveUS6866669B2Easy and accurate deployment and positioningEasy to operateStentsEar treatmentLocking mechanismMedical device
A system for delivering at least one medical device to a desired location for treatment, and then selectively deploy it in position, includes an improved handle. One of the possible features of the handle may be to selectively hold the delivery system components at any desired configuration during deployment and positioning of the medical device. Another possible feature of the handle may be more than one mode of operation, in which the deployment of the medical device can selectively proceed at more than one speed. Yet another possible feature of the handle may be a locking mechanism that resists inadvertent or accidental movement or retraction of the stent delivery system components during packaging, sterilization, shipping, storage, handling and preparation of the stent delivery system.
