Abstract
An insertion needle that is turnably mounted on a handle, which holds the insertion needle, wherein the insertion needle includes a turn arm that turns so as to face the tip of the insertion needle, and a target site that guides the insertion needle provided on the tip of the turn arm, and is further provided with: through-holes in two locations that are provided separated in the longitudinal direction of the tip of the insertion needle; an indentation formed between these through-holes; and a groove in the direction from the tip of the insertion needle toward the base of the insertion needle. Furthermore, the insertion needle is suitably used in urinary incontinence surgery, pelvic organ prolapse surgery or the like.
Claims3
A surgical needle apparatus, comprising:
- a main body configured as a needle so as to have a distal end adapted to insert into a body cavity or through tissue, and having a proximal end opposite the distal end;
- the main body extending so as to curve along a length from the proximal end to the distal end;
- the main body having a radially-extending first passage in a first plane transverse to said length at a first longitudinal location along said length, and having a radially-extending second passage at a second plane transverse to said length at a second longitudinal location along said length;
- said first passage and said second passage each having a first opening adapted for passing a surgical thread therethrough;
- the main body including a reduced-diameter first section along said length between said first longitudinal location and said second longitudinal location, said reduced-diameter section being solid along an entire length of said reduced-diameter section and adapted so that said surgical thread would traverse exterior to an outer surface of said reduced-diameter section as the surgical thread extends from the first passage to the second passage;
- and
- the main body having a groove extending longitudinally along an outer surface of the main body from a second opening of said first passage toward said proximal end without traversing said reduced-diameter first section.
