Abstract
Abstract A suture passer comprises a longitudinally extending hollow cannula having a central passage slidingly receivable of a surgical suture; a manually graspable handle connected to the hollow cannula for manipulation thereof, the handle having an upper surface; first guide member, connected to the upper surface of the handle, proximate a distal end of the handle for releasably, guidingly, holding the surgical suture; second guide member, connected to the upper surface of the handle, proximate to the first guide member, for releasably, guidingly, holding the surgical suture. The suture passer can be provided in a kit, for use in the suturing of internal tissue, along with a cannula bender, various hollow surgical needles and surgical suture material. The suture passer finds particular use in the suturing of internal tissues which are at least partially accessible through a body cavity, e.g. arthroscopic surgery.

A suture passer according to claim 1 further comprising means for disengaging said cannula from said handle.
Claim 4
Dependent Claim
57 words
A suture passer according to claim 1 wherein said tubular cannula includes a proximal portion, and further wherein said proximal portion of said cannula is receivable within a first bore formed in said handle, said bore terminating at a distal opening adjacent to said upper surface of said handle intermediate said first and second suture guide means.
Claim 5
Dependent Claim
109 words
A suture passer according to claim 3 wherein said means for releasably, lockingly maintaining said cannula in a fixed position relative to said handle comprises: a thin radial fin extending outwardly from said proximal portion of said cannula; a longitudinal slot extending into said distal end of said handle and communicating with said first bore, said slot including a pair of side walls separated by a gap slightly larger than the thickness of said fin; and means for restricting axial movement of said cannula relative to said handle; whereby said fin may slide into said slot as said proximal portion of said cannula is engaged in said first bore.
Claim 6
Dependent Claim
129 words
A suture passer according to claim 4 wherein said means for restricting axial movement of said cannula relative to said handle comprises: a tab extending proximally from said fin, said tab including at least one tab projection defining a distally facing tab shoulder; a proximal end of said slot; a cavity in said handle located immediately proximally of said slot, said cavity having sidewalls defining at least one sloping, inwardly extending sidewall projection defining a proximally facing sidewall shoulder; and said tab being configured to enter said cavity as said cannula is inserted into said first bore and said fin slides into said slot, such that said at least one distally facing tab shoulder will form a snap lock engagement against said at least one proximally facing sidewall shoulder.
Claim 7
Dependent Claim
135 words
A suture passer according to claim 5 wherein a second bore extends axially and proximately through said handle from said cavity to said proximal end of said handle and a release rod is slidably mounted in said second bore for reciprocal movement between a distalmost position and a proximalmost position, said release rod having a proximal portion extending proximally of said proximal end of said handle and a distal end, whereby distal movement of said proximal portion of said release rod will cause said release rod to move from said proximalmost position toward said distalmost position so that said distal end of said release rod will deflect said tab laterally so as to disengage said at least one distally facing tab shoulder from said lock engagement with said at least one proximally facing sidewall shoulder.
Claim 8
Dependent Claim
16 words
A suture passer according to claim 6 wherein said release rod comprises a bevelled distal end.
Claim 9
Dependent Claim
75 words
A suture passer according to claim 7 wherein said release rod comprises a drive surface proximal to its bevelled surface, and further wherein distal movement of said proximal portion of said release rod from said proximalmost position to said distalmost position will cause said drive surface to engage said tab and move said cannula distally after said at least one distally facing tab shoulder is disengaged from said at least one proximally facing sidewall shoulder.
