| 摘要 |
An apparatus for remotely and subcutaneously positioning a tethering strand in tissue includes a housing, an actuator coupled with the housing for longitudinal reciprocation relative to the housing, and a nested pair of needles including a first needle coupled with the housing and a second needle coupled with the actuator. One of the needles has a sharpened tip and another one of the needles has a blunted tip. The first needle has a first length and the second needle has a second length, and the first length and the second length are selected so that advancement of the second needle using the actuator causes the sharpened tip to project beyond the blunted tip, and so that retraction of the second needle using the actuator causes the blunted tip to project beyond the sharpened tip. |

1. An apparatus for remotely and subcutaneously positioning a tethering strand in tissue, wherein the apparatus comprises a housing, an actuator coupled with the housing for longitudinal reciprocation relative to the housing, and a nested pair of needles including a first needle coupled with the housing and a second needle coupled with the actuator, wherein one of the needles has a sharpened tip and another one of the needles has a blunted tip, wherein the first needle has a first length and the second needle has a second length, and wherein the first length and the second length are selected so that advancement of the second needle using the actuator causes the sharpened tip to project beyond the blunted tip, and so that retraction of the second needle using the actuator causes the blunted tip to project beyond the sharpened tip. |
