Percutaneous Tissue Access Device
First Claim
1. A surgical device for percutaneously accessing a tissue of interest comprising:
- a handle including a longitudinal groove;
a resilient member disposed within the groove;
a locking sleeve at least partially disposed within the groove and slidingly engaging the groove, wherein the locking sleeve has a first end engaging and compressing the resilient member and a second end extending beyond the groove, and wherein the second end includes a flange defining a locking recess having a non-circular cross-section;
a cannula including a locking end and an axial through bore, wherein the locking end includes a locking flange having a non-circular cross-section;
wherein the non-circular cross-section of the locking flange and the non-circular cross-section of the locking recess are adapted to prevent the rotation of the cannula relative to the locking sleeve when the locking flange is at least partially received by the locking recess; and
means for rotationally coupling the cannula to the handle.

13. A surgical device for percutaneously accessing a tissue of interest comprising:
-
a handle including an axial annular groove defining an axial post, wherein the axial post has a threaded portion; a resilient member disposed within the annular groove; an annular locking sleeve partially disposed within the annular groove, wherein the annular locking sleeve has a first end engaging and compressing the resilient member and a second end extending beyond the annular groove, wherein the second end includes a flange having a locking recess with a noncircular cross-section; and a cannula including a locking end and an axial through bore, wherein the locking end includes a locking flange having a non-circular cross-section, and wherein the axial through bore has an threaded portion adapted to mate with the threaded portion of the axial post; wherein the non-circular cross-section of the locking flange and the non-circular cross-section of the locking recess are adapted to prevent the rotation of the cannula relative to the locking sleeve when the locking flange is at least partially received by the locking recess; wherein the surgical device has a locked position with the cannula threadibly coupled to the axial post and the locking flange at least partially received within the locking recess. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
