A medical device may include a shaft, and a first tool extending from a distal end of the shaft. The medical device also may include a control assembly coupled to the shaft. The control assembly may include a console, a first grip extending proximally from the console, and a second grip extending proximally from the console. The control assembly also may include a first deflection actuator configured to deflect the first tool about a longitudinal axis of the first tool, a first rotation actuator configured to rotate the first tool about the longitudinal axis of the first tool, and a first longitudinal actuator configured to move the first tool along the longitudinal axis of the first tool.

Provided is a method performing vascular surgery utilizing a guiding apparatus that includes an adaptor and an introducer, by inserting a longitudinal section of the adaptor into the introducer and operating a valve of the introducer by moving a cursor provided on a side wall of the introducer within a travel region of the cursor. Operating the valve either fixedly attaches or releases the longitudinal section of the adaptor within or from the introducer. The adaptor includes an inner volume that encloses a plurality of ducts and the introducer includes an inner volume that aligns with the inner volume of the adaptor when the valve is fixedly attached the longitudinal section of the adaptor within the introducer, thereby providing ducts that allow an instrument to pass entirely through both the adaptor and the introducer.

A surgical access port comprises an instrument guide. The instrument guide comprises a proximal end, a distal end, a plurality of instrument guide channels between the proximal and distal ends, and an outside surface that fits closely to an inner wall surface of a cannula into which the instrument guide is inserted. The instrument guide also comprises a first guide channel opening defined along a length of a first guide channel of the plurality of instrument guide channels. The instrument guide also comprises a second guide channel opening defined along a length of a second guide channel of the plurality of instrument guide channels. The instrument guide also comprises an insufflation channel defined between the first and second guide channel openings. The insufflation channel extends from a position between the proximal and distal ends of the instrument guide to the distal end of the instrument guide.

Disclosed herein are devices and methods for introducing a plurality of instruments to a target site through a working channel. The working channel can include a surface adapted to guide one or more instruments into select positions. The working channel can be defined by a portion of a guide tube or tip that may be coupled with an endoscope.

A surgical access port comprises a seal and an instrument guide, which comprises proximal and distal ends, a plurality of instrument guide channels, and an outside surface that fits closely to an inner wall surface of a cannula into which the instrument guide is inserted. The seal is positioned to seal between the instrument guide and the inner wall surface as the instrument guide rotates within the cannula. A first guide channel is configured to support a first surgical instrument at a first defined position within the cannula. A second guide channel is configured to support a second surgical instrument at a second defined position within the cannula. A first guide channel opening is defined along a length of the first guide channel to be open to the outside surface of the instrument guide and place a portion of the first surgical instrument adjacent the inner wall surface.

An access apparatus includes an access housing, an access member extending from the access housing, a fluid connector mounted to the access housing and a control valve mounted to the fluid connector. The control valve is positionable relative to the fluid connector between a first position corresponding to a desufflation operative state permitting rapid desufflation of the underlying body cavity, a second position corresponding to an insufflation operative state permitting insufflation fluid flow into the access member and into the underlying body cavity, and a third position corresponding to a closed operative state.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
