摘要:
Devices and methods for performing percutaneous surgery under direct visualization through a single cannula are shown. A device includes an elongated cannula sized for percutaneous introduction that defines a working channel between its ends. The working channel is sized to receive one or more surgical tools therethrough. A clamp assembly is engaged to the outer surface of the cannula. The clamp assembly includes a viewing element receiving portion and a viewing element includes a clamp assembly engaging portion for removably engaging the viewing element to the clamp assembly. In one embodiment, the receiving portion defines a receptacle for receiving a dovetail included on the engaging portion of the viewing element. The receiving portion may also include a pivotable clip for removably engaging a protuberance of the engaging portion. The clamp includes a mechanism that allows translation, rotation, and removal of the clamp assembly and the viewing element with respect to the cannula. The cannula may also be engaged to a flexible arm that is securely mounted in order to stabilize the position of the cannula at the surgical site.

Methods and devices for performing percutaneous surgery in a patient are provided. A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are movable relative to one another from an unexpanded configuration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimizing trauma to skin and tissue.

Methods and devices for illuminating a surgical space during surgery in a patient are provided. A retractor provides a working path for access to a location in the patient. A light instrument is positionable in working channel to emit light at the surgical space without substantially obstructing access to the surgical space.

Methods and devices for illuminating a surgical space in a patient are provided. A retractor provides a portal or working path for access to a working space location in the patient. The retractor transmits and emits light from a light delivery system to illuminate the working channel and surgical space.

Methods and devices for performing surgery in a patient are provided. A cannula provides a working channel for access to a location in the patient. A clamp assembly is removably engaged to the cannula. The clamp assembly allows use of an endoscopic viewing system or can be removed to allow use of a microscopic viewing system in order to view the surgical site in the patient through the working channel. The clamp assembly includes a viewing element mounting portion having a length along which an endoscopic viewing element can be selectively positioned.

Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another.
