a table in which searching orders are allocated to respective tag numbers, wherein the searching action controller controls searching for positions corresponding to the tag numbers allocated by the table referring to the layout drawing.
5. The capping system according to claim 4, further comprising:
a memory memorizing detected positions of optical semiconductor elements mounted on respective stems; and
a search starting point setting portion setting a distribution center of the detected positions as the search starting point.
6. A capping system comprising:
a moving portion moving a stem, on which an optical semiconductor element is mounted, horizontally;
a fixer fixing a cap having a window to the stem so the cap covers the stem;
a camera taking an image of the cap and the stem from above the cap and the stem;
a detector detecting whether the optical semiconductor element is present within a visual field of the camera;
a searching action controller controlling the moving portion to move the stem for searching the optical semiconductor element;
a memory memorizing detected positions of optical semiconductor elements mounted on respective stems; and
a search starting point setting portion setting a distribution center of the detected positions as a search starting point, wherein the searching action controller controls the searching from the search starting point.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for fixing a piece of tissue in a bone tunnel in a bone, the method comprising the steps of:
advancing a first trocar and sleeve assembly through the bone and toward the bone tunnel;
advancing a second trocar and sleeve assembly through the bone and toward the bone tunnel;
each of the assemblies comprising a trocar disposed within a sleeve and having a sharpened end extending beyond an end of the sleeve, the trocar substantially filling the sleeve within which the trocar is disposed;
the first and second assemblies being advanced spaced apart and generally normal to the bone tunnel;
placing a bone block having the piece of tissue attached thereto in the bone tunnel;
withdrawing the first trocar from the first sleeve, leaving the first sleeve in the bone;
advancing a first bio-absorbable rod into the first sleeve and through the bone block;
withdrawing the first sleeve from the bone block and the bone, leaving the first bio-absorbable rod in place;
withdrawing the second trocar from the second sleeve, leaving the second sleeve in the bone;
advancing a second bio-absorbable rod into the second sleeve and through the bone block; and
withdrawing the second sleeve from the bone block and the bone, leaving the second bio-absorbable rod in place;
wherein the rods retain the bone block, and thereby the piece of tissue, in the bone tunnel; and
wherein the bio-absorbability of the rods is such as to enable absorption of the rods by a body in which the rods are disposed over time, such that the tissue is initially attached to the bone by the rods and, subsequently, the rods are absorbed into the body.
2. A method according to claim 1 wherein the rods are of a material selected from a group consisting of polylactic acid, polyglycolic acid and polydiaxanone.
3. The method according to claim 1 wherein the rods are formed of a material selected from a group consisting of substantially rigid metals, plastics and ceramics.
4. A method according to claim 1 wherein the trocars each define a tip adapted to drill through the bone by rotation about a longitudinal axis thereof.
5. A method for fixing a piece of tissue in a bone tunnel in a bone, the bone tunnel having a substantially closed distal end and an open proximal end, the method comprising the steps of:
placing a bone block having the piece of tissue attached thereto in the bone tunnel adjacent the substantially closed distal end of the bone tunnel, with the tissue extending outwardly from the open proximal end of the bone tunnel; and
advancing a rod through the bone and across the bone tunnel adjacent to a proximal end of the bone block;
whereby to capture the bone in the bone tunnel between the substantially closed end of the bone tunnel and the rod.
