Abstract
A surgical guidewire device includes an outer tube and a guide needle. The outer tube has a needle tip formed at a tube distal end of the outer tube. The guide needle is movably disposed in the outer tube and has a needle eye structure. When the surgical guidewire device is in use, a suture extends through the needle eye structure, and is carried through the outer tube along with the needle eye structure as the guide needle is moved relatively toward the tube distal end and then away from the outer tube.

A surgical guidewire device comprising:
- an outer tube being hollow and extending along an axial direction and comprising:
- a tube distal end,
- a tube proximal end, and
- a needle tip being formed at the tube distal end;
- a guide needle movably disposed within the outer tube and comprising:
- a needle proximal end, and
- a needle eye structure being hollow and formed at the needle proximal end;
- and
- a guidewire block configured to selectively prevent movement of the guide needle into an incision of a patient, the guidewire block comprising:
- a fixing part detachably engaged to the outer tube or the guide needle, and
- a guidewire part comprising a treading structure,
- wherein, when the guidewire block is engaged to the tube proximal end or the needle proximal end, at least a part of the guidewire part and the treading structure extend through the needle eye structure for receiving a tissue fixation material.
