A method for autotransplantation, is provided including the steps of (a) obtaining a piece of tissue from one part of a body, (b) preserving the tissue by contacting it with a tissue preserving medium, without tissue culturing occurring, and (c) grafting the tissue in another part of the body. The method is especially advantageous for the repair of hypospadias using buccal mucosa tissue. The tissue preserving medium preferably is a solution of (a) 80-120 mM NaCl, (b) 3-6 mM KCl, (c) 0. 1-0. 3 mM MgSO. sub. 4. 7H. sub. 2 O, (d) 1-3 mM CaCl. sub. 2. 2H. sub. 2 O, (e) 0. 2-0. 6 mM NaH. sub. 2 PO. sub. 4, (f) 1. 5-4 mM glucose, (g) 15-25 mM Na lactate, (h) 0. 2-0. 6 mM Na pyruvate, (i) 0. 01-0. 05 mM phenol red, (j) 0. 1-0. 4 mM L-glutamine, (k) 2-35 mM sodium bicarbonate, (l) 125-200 units/ml penicillin-G, (m) 40-60. mu.

A needle holding device includes a handle, a pivot point and two opposing jaws opposite the handle and pivotable about the pivot point. The jaws have inner opposing surfaces and at least one inner opposing surface has at least one needle groove formed therein for receiving and gripping a needle. At least one of the opposing surfaces has a knurled or rugged platform for securely gripping at least one needle. The needle holding device may have a plurality of substantially parallel or non-parallel needle grooves formed therein for simultaneously receiving and gripping a plurality of needles. Additionally, the plurality of non-parallel needle grooves preferably includes an innermost needle groove disposed nearest to the pivot point and an outermost needle groove disposed furthest from the pivot point, wherein the plurality of needle grooves successively increase in depth from the outermost needle groove to the innermost needle groove so that a plurality of needles can be simultaneously held regardless of needle size or position within the holder.

The invention is directed to a microsurgical needle for use in microsurgical techniques. The distal segment of the needle is straight with a circular cross section, and has a sharpened tip with a triangular cross section having three sharp edges for cutting rather than tearing tissue during penetration. The middle segment of the needle has an acutely angled arched shape, and a transitional cross section which transitions between a squared cross section of the main shaft segment and the circular cross section of the straight distal segment. The main shaft segment of the needle has a generally squared cross section, and forms a broadly curved or arched shaft segment which may be easily gripped by a needle holder. The proximal end of the needle forms a suture attachment segment, and may be circular in cross section. The shape of the needle provides an easy angle, better stability, superior tissue alignment, and better control than conventional.
