Method and apparatus for cannula fixation for an array insertion tube set

摘要

An instrument holding system for a drive system is provided. The system can include an array holder that defines at least one bore for receipt of an instrument therethrough. The at least one instrument can be adapted for insertion into an anatomy. The array holder can be in communication with the drive system to receive a driving force. The system can include a fixation plate operable to move relative to the array holder such that the fixation plate is in contact with at least a portion of the at least one instrument to couple the at least one instrument to the array holder to enable the at least one instrument to be driven by the driving force into the anatomy.

1. A system comprising:
a block configured to connect to and receive a driving force from a driver, wherein the block comprises (i) mating surfaces extending in a first direction, and (ii) a first bore extending through the block in a second direction perpendicular to the first direction, and wherein the first bore is configured to guide a first cannula in or out of a patient in the second direction; and a guide member connected to the block and having a second bore, wherein the second bore is aligned in the second direction with the first bore of the block; and a plate configured to be moved in the first direction relative to the block, wherein
the plate comprises a pair of members and a slot,the slot extends in the first direction and is configured to receive a first electrode of the first cannula,the pair of members extends from and is perpendicular to the plate,the pair of members engages with the mating surfaces of the block such that a gap exists between the block and the plate, wherein the gap is sized such that a first depth stop mounted on the first cannula is received in the gap and on an uppermost surface of the block, and wherein when the plate is slid on the block, the gap exists between the uppermost surface of the block and an opposing inner surface of the plate, andthe pair of members is configured to be slid on the mating surfaces such that (i) the first cannula is received in the slot of the plate, (ii) the first depth stop is received in the gap, and (iii) the first cannula is driven by the plate into the patient as a result of the driving force exerted on the block.
