摘要:
In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise at least one energy delivery surface and heat dissipation means for dissipating heat from at least a portion of the end effector. For example, in at least one embodiment, the end effector may comprise a first jaw, a second jaw, and a cutting member. The cutting member may comprise a cutting surface and a body, which may define a cavity and at least one opening communicating with the cavity. A fluid may be moved through the cavity to and/or from the opening(s). Additionally, in at least one embodiment, a surgical instrument's end effector may comprise a first jaw, a second jaw, a cutting member, and at least one heat pipe. Various other heat dissipation means are also disclosed.

An electrosurgical instrument for scoring, welding and transecting tissue is provided. The electrosurgical instrument comprises first and second openable-closeable jaws and at least one scoring electrode extending from a distal end of at least one of the first and second openable-closeable jaws. The first and second openable-closeable jaws comprises first and second conductive tissue engaging surfaces, respectively, and first and second insulating members, respectively. The scoring electrode is coupled with at least one of the first and second insulating members. The at least one scoring electrode can be activated independently from the first and second openable-closeable jaws so that the electrosurgical instrument can independent score tissue and weld tissue.

Intervertebral devices and systems, and methods of their use, are disclosed having configurations suitable for placement between two adjacent vertebrae, replacing the functionality of the disc therebetween. Intervertebral devices and systems contemplated herein are implantable devices intended for replacement of a vertebral disc, which may have deteriorated due to disease for example. The intervertebral devices and systems are configured to allow for ample placement of therapeutic agents therein, including bone growth enhancement material, which may lead to better fusion between adjacent vertebral bones. The intervertebral devices and systems are configured for use in minimally invasive procedures, if desired.

In some embodiments, a tissue removal system may comprise a handheld housing and a tissue collection chamber coupled to a distal portion of the handheld housing and comprising a cylindrical portion, a motor, and an articulation mechanism. The articulation mechanism may comprise a shaft comprising an outer tubular member and an inner tubular member disposed within the outer tubular member and coupled to the cylindrical portion of the tissue collection chamber, a drum component slidably engaged with the cylindrical portion of the tissue collection chamber and coupled to the outer tubular member, an articulation drive component rotatably coupled to the drum component and to the cylindrical portion of the tissue collection chamber, and a tissue removal assembly coupled to the shaft and operable by the motor. The shaft may be articulated by rotating the articulation drive component and causing the drum component to translate in a proximal direction.
