Abstract
A medical instrument includes a guide (102) having an interlocking structure. A tool (104) is enclosed within the guide and has an interlocking feature configured to engage the interlocking structure of the guide. The tool has a stored position and a deployed position such that in transitioning between the stored position and the deployed position, motion of the tool relative to the guide is controlled in accordance with the interlocking structure.
Claims16
A medical instrument, comprising:
- a guide (102) having an interlocking structure;
- and
- a tool (104) comprising a component having a functional portion extendable from a distal end portion of the tool, said tool is enclosed within the guide and having an interlocking feature configured to engage the interlocking structure of the guide;
- the tool having a stored position and a deployed position wherein the functional portion extends beyond the interlocking structure of the guide such that in transitioning between the stored position and the deployed position, motion of the tool relative to the guide is controlled in accordance with the interlocking structure.
