Abstract
An instrument for tensioning a flexible elongate member in a surgical procedure includes a tensioning mechanism engageable to a portion of the flexible elongate member and operable to apply a tensioning force to the elongate member. The instrument includes a distal end portion at a distal end of the tensioning mechanism that is adapted to allow orientation of the elongate member in a first direction for implantation and to allow the instrument to extend transversely to the implantation orientation during application of a tensioning force. The distal end portion can also include a receptacle to receive a structure at the surgical site to facilitate positioning of the distal end portion at the desired location.
Claims35
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to the flexible elongate member and operable to apply a tensioning force thereto;
- and
- a distal end portion at a distal end of said tensioning mechanism including a receptacle opening at a distal end of said distal end portion and said opening extending from said distal end along at least one side of said distal end portion, said receptacle being sized to at least partially receive a structure at the surgical site when said distal end portion is positioned at the surgical site, wherein said distal end portion includes a support member and during application of the tensioning force a portion of the elongate member extending from the distal end portion is orientable in a first direction for implantation and the elongate member contacts said support member for orientation of a second portion of the elongate member in a second direction along said tensioning mechanism.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to the flexible elongate member and operable to apply a tensioning force thereto;
- and
- a distal end portion at a distal end of said tensioning mechanism including a receptacle opening at a distal end of said distal end portion and said opening extending from said distal end along at least one side of said distal end portion, said receptacle being sized to at least partially receive a structure at the surgical site when said distal end portion is positioned at the surgical site, wherein said distal end portion includes a housing, said housing including opposite end walls extending between opposite side walls, said end walls and said side walls extending about said receptacle, at least one of said end walls including a passage in communication with said receptacle and said at least one end wall includes a pair of abutment members extending outwardly therefrom, said abutment members being spaced from one another along opposite sides of said passage.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to the flexible elongate member and operable to apply a tensioning force thereto;
- and
- a distal end portion at a distal end of said tensioning mechanism including a receptacle opening at a distal end of said distal end portion and said opening extending from said distal end alone at least one side of said distal end portion, said receptacle being sized to at least partially receive a structure at the surgical site when said distal end portion is positioned at the surgical site, wherein said distal end portion includes a housing, said housing including opposite end walls extending between opposite side walls, said end walls and said side walls extending about said receptacle, at least one of said end walls including a passage in communication with said receptacle and said housing include a bore extending proximally therethrough in communication with said receptacle, said housing further including a support member offset from said bore toward said at least one end wall.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to the flexible elongate member and operable to apply a tensioning force thereto;
- and
- a distal end portion at a distal end of said tensioning mechanism including a receptacle opening at a distal end of said distal end portion and said opening extending from said distal end along at least one side of said distal end portion, said receptacle being sized to at least partially receive a structure at the surgical site when said distal end portion is positioned at the surgical site, wherein said distal end portion includes a housing, said housing including:
- a collar;
- opposite end walls extending distally from said collar;
- opposite side walls extending distally from said collar and between said opposite end walls;
- and
- at least one of said end walls and said opposite side walls each including a flared wall portion to separate said at least one end wall and said opposite side walls from one another, said receptacle being defined at least in part by said separated end wall and opposite side walls.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to a first portion of the elongate member and operable to apply a tensioning force to the elongate member;
- and
- a distal end portion at a distal end of said tensioning mechanism, said distal end portion including a support member contactable with the elongate member to orient said tensioning mechanism in a first direction relative to a second portion of the elongate member extending distally from the tensioning mechanism in a second direction that is transverse to said first direction.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to a portion of the flexible elongate member and operable to apply a tensioning force to the elongate member;
- and
- a distal end portion at a distal end of said tensioning mechanism, said distal end portion including a housing and a support member within said housing contactable with the elongate member to change an orientation of the portion of the elongate member engaged with said tensioning mechanism relative to a portion of the elongate member extending from said housing from said support member.
An instrument for tensioning a flexible elongate member in a surgical procedure, comprising:
- a tensioning mechanism engageable to the flexible elongate member and operable to apply a tensioning force thereto;
- and
- a distal end portion at a distal end of said tensioning mechanism including a receptacle opening at a distal end of said distal end portion and said opening extending from said distal end along at least one side of said distal end portion, said receptacle being sized to at least partially receive a structure at the surgical site when said distal end portion is positioned at the surgical site, wherein said distal end portion includes a support member in contact with the elongate member, said support member being rotatable about an axis transversely oriented to the elongate member.
