    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.

    摘要: Devices and methods for performing percutaneous spinal surgery under direct visualization and through a single cannula are shown. A device (10) is provided which includes an elongated cannula (20) having a first inner diameter (DI) and an outer diameter (DO) sized for percutaneous introduction into a patient. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D2) equal to the diameter (DI) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30). The fixture (30) includes a housing (31) attachable to the proximal end (22) of the cannula (20) that defines a working channel opening (35) which is in communication with the working channel (25). The housing (31) also defines an optics bore (60) adjacent the working channel opening (35). In certain embodiments, the fixture (30) supports the viewing element (50) for translation and/or rotation within the optics bore (60) along the longitudinal axis of the bore, and for rotation of the housing (31) relative to the cannula (20) so that the longitudinal axis of the optics bore (60) will rotate about the longitudinal axis of the working channel (25). Methods are also provided for performing spinal surgeries percutaneously with direct visualization and without the requirement for a fluid-maintained workspace.

The fixture (30, 170) includes a housing/body (31, 171) attachable to the proximal end (22) of the cannula (20). The housing (31) defines an optics bore (60, 180) to support a viewing element (50) for translation and rotation relative to the cannula (20) so that the longitudinal axis of the optics bore (60, 180) will translate parallel to and rotate about the longitudinal axis of the working channel (25).

    摘要: Devices and methods for performing percutaneous spinal surgery under direct visualization and through a single cannula are shown. A device (10) is provided which includes an elongated cannula (20) having a first inner diameter (D.sub.I) and an outer diameter (D.sub.O) sized for percutaneous introduction into a patient. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D.sub.2) equal to the diameter (D.sub.I) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30). The fixture (30) includes a housing (31) attachable to the proximal end (22) of the cannula (20) that defines a working channel opening (35) which is in communication with the working channel (25). The housing (31) also defines an optics bore (60) adjacent the working channel opening (35). In certain embodiments, the fixture (30) supports the viewing element (50) for translation and/or rotation within the optics bore (60) along the longitudinal axis of the bore, and for rotation of the housing (31) relative to the cannula (20) so that the longitudinal axis of the optics bore (60) will rotate about the longitudinal axis of the working channel (25). Methods are also provided for performing spinal surgeries percutaneously with direct visualization and without the requirement for a fluid-maintained workspace.
