Minimally invasive surgery (MIS) assembly
A surgical tool adaptor includes a distal interface member and a proximal holder. The surgical tool adaptor is formed with a lumen through the distal interface member and the proximal holder for passing a guiding element (e.g., K-wire) distally through the distal interface member. The proximal holder includes a locking element for locking the guiding element in the lumen and the distal interface member includes a connecting element for connecting to a surgical tool. The proximal holder is movable relative to the distal interface member so that the proximal holder is movable to a position wherein the guiding element does not protrude proximally out of the proximal holder.
1. An assembly comprising:
a surgical tool adaptor comprising a distal interface member for connecting to a surgical tool; and
a proximal holder rotatable with respect to said distal interface member, wherein a lumen is formed through said distal interface member and said proximal holder for passing therethrough a guiding element;
said proximal holder comprising a capturing element for capturing the guiding element in said lumen, and said distal interface member comprising a connecting element for connecting to a surgical tool,
wherein said proximal holder is axially movable relative to said distal interface member so that said proximal holder is movable to a position wherein the guiding element does not protrude proximally out of said proximal holder, wherein capturing of said guiding element by said capturing element is independent of movability of said proximal holder relative to said distal interface member, and wherein after said guiding element is captured, said proximal holder is movable relative to said distal interface member to move said guiding element more distally or more proximally relative to said distal interface member.
2. The assembly according to claim 1 , wherein said proximal holder is threadingly mounted on a shaft and rotation of said proximal holder on said shaft moves said proximal holder axially relative to said distal interface member.
3. The assembly according to claim 1 , wherein said proximal holder comprises a proximal face for striking with a striking tool.
4. The assembly according to claim 1 , wherein said connecting element comprises a threaded element for threaded connection with the surgical tool.
5. The assembly according to claim 1 , wherein said connecting element comprises a male or female connector for connection with the surgical tool.
6. The assembly according to claim 1 , further comprising a handle for turning said surgical tool adaptor.
7. The assembly according to claim 1 , wherein said proximal holder is rotatable with respect to said distal interface member.
8. The assembly according to claim 1 , wherein said guiding element comprises a K-wire.
9. The assembly according to claim 1 , further comprising a force sensor mounted on said guiding element.
10. A method comprising:
using the assembly of claim 1 , passing a guiding element through said distal interface member and said proximal holder, capturing said guiding element by said capturing element, and wherein after said guiding element is captured, moving said proximal holder relative to said distal interface member to move said guiding element more distally or more proximally relative to said distal interface member.
