Surgical instruments, such as distractors and methods of manufacture are provided for maintaining a displacement of bone determined to be necessary by a surgeon. For instance, a surgical distractor may include a first holder section, a second holder section, a first displacement element, a second displacement element, a positioning element, and a rotatable component having an opening. The second holder section may be coupled to the first holder section using one or more coupling elements coupled to both the first holder section and the second holder section. The first displacement element and the positioning element may be positioned on the first holder section and the second displacement element and the rotatable opening may be positioned on the second holder section configured to engage the first displacement element.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.

Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.

A cuff is described for a target anatomic feature within a body, along with a system for utilizing the cuff. The cuff includes a band defining a circumferential opening extending along a length of the band; and a pair of engagement surfaces defined by or affixed to the cuff, the engagement surfaces structured for application of a spreading force to be distributed continuously along a portion of the circumferential opening, thereby increasing the circumferential opening and expanding the cuff for a closed configuration to an open configuration sized for placement of the cuff. The cuff is structured to remain in the closed configuration in the absence of the spreading force and automatically return to the closed configuration after removal of the spreading force.

A surgical tool for separating two components, for example removing a femoral head from a femoral stem, having a four bar chain whose four bars are a first handle (L1), an crossover component (L2), a second handle (L3) and a crossbar (L4) pivotally connected respectively by: a first joint (J1) between the first handle and the crossover component; a second, crossover joint (J2) between the crossover component and the second handle; a third joint (J3) between the second handle and the crossbar, and a fourth joint (J4) between the crossbar and the first handle, and wherein, upon application of a gripping force to the first and second handles, the first and second jaws separate from one another so as to separate the two components engaged therewith.

An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.

A surgical towel clamp apparatus includes a first elongated element having a curved tip and a right finger ring, a second elongated element having a curved tip and a left finger ring, wherein the first and second elongated elements are coupled at a first pivot point, a third elongated element having a straight tip and coupled to the right finger ring, a fourth elongated element having a straight tip and coupled to the left finger ring, wherein the third and fourth elongated elements are coupled at a second pivot point, wherein in an open orientation, the rings are apart, the curved tips are apart, and the straight tips are apart, and wherein in a closed orientation, the left and right finger rings are adjacent, the curved tips are in contact and the straight tips are in contact.

A surgical instrument includes an ultrasonic waveguide extending through a body assembly. An ultrasonic blade connects to the ultrasonic waveguide. A clamp arm assembly of the surgical instrument is able to move from an opened position for receiving a tissue toward a closed position for clamping the tissue. The clamp arm assembly includes a clamp body and a clamp pad facing the ultrasonic blade. A clamp arm actuator of the surgical instrument is able to move from a first position toward a second position to direct the clamp arm assembly from the opened position toward the closed position. A modular coupling of the surgical instrument connects to the clamp pad such that at least the clamp pad can be disconnected relative to the ultrasonic blade for replacement thereof.

A surgical end effector assembly is disclosed. The surgical end effector assembly comprises a shaft, an end effector comprising a first jaw and a second jaw movable relative to the first jaw, and an articulation joint attaching the end effector to the shaft, wherein the articulation joint defines an articulation axis about which said end effector is articulatable relative to the shaft. The articulation joint comprises a first rotary drive member rotatable about the articulation axis and a second rotary drive member rotatable about the articulation axis, wherein the first rotary drive member and the second rotary drive member are rotatable in the same direction to articulate the end effector about the articulation axis. The surgical end effector assembly further comprises a jaw drive output cooperatively driven by the first rotary drive member and the second rotary drive member configured to clamp and unclamp tissue with the second jaw.

A surgical device includes a forceps device that performs a bending movement and opening and closing movements of grasping portions of the forceps device, driven portions to which a driving force is transmitted from outside the surgical device, and plural cords, each being fixed to one of the driven portions, the cords transmitting movements of the driven portions to the forceps device. The forceps device performs one or both of the bending movement and the opening and closing movements when all or a portion of the cords are pulled.
