In a method and system for corrective surgery of a bone, a bone is cut into a first bone segment and a second bone segment. A plate is positioned over the first bone segment and the second bone segment such that at least one member of the plate is positioned to engage the second bone segment. The at least one member of the plate is inserted into the second bone segment. At least one bone screw is screwed into the first bone segment through at least one compression slot of the plate causing an application of compressive force to secure the first bone segment and the second bone segment to form a corrective construct. The at least one member is positioned at an angle or an offset from the second plate segment

A method for corrective surgery in a human subject of a vocal cord defect amenable to rectification by the augmentation of tissue subadjacent to the vocal cord defect, the method comprising: placing an effective amount of autologous in vitro cultured cells into a vocal cord tissue of the subject in a position subadjacent to the vocal cord defect, wherein the vocal cord tissue is selected from the group consisting of a scar, Reinke's space, a muscle of the vocal cord, and the lamina propria, wherein the in vitro cultured cells are obtained by culturing a plurality of viable cells retrieved from the subject, and wherein the cultured cells are suspended in a collagen or modified collagen solution prior to injection of the cultured cells. The in vitro cultured cells can be fibroblasts, e.g., fibroblasts derived from dermis, fascia, connective tissue, or lamina propria.

In a preferred application, e.g., the repair of vaginal prolapse after relocation of the vagina and any organs displaced by the prolapse, corrective surgery is initiated by applying a hollow tubular element, formed to forcibly insert a barbed anchor attached to a distal end of a first length of suture, without any incision, from the inside of the vagina through the vaginal wall (the supported tissue) into selected support tissue within a patient's pelvis. This involves puncturing and thus locally severe physical distressing of both the supported tissue and the support tissue. The barbed anchor is left in the support tissue as the tubular element is then withdrawn from the support tissue and out of the vagina, leaving the proximate end portion of the suture extending through the vaginal wall into the vagina. A second such anchor, with a second length of suture attached thereto, is similarly inserted adjacent to the first anchor. The proximate end portions of the sutures are tied to each other inside the vagina, to thereby secure the vaginal wall to the support tissue with corresponding punctures formed in each by the insertions of the two anchors being thereby held in respective, precisely aligned, intimate contact during healing. This results in a pair of fused scars that cooperate to permanently bond the vaginal wall locally to the support tissue. If the sutures and / or the anchors are made of absorbable material they will all eventually disappear and the fused scars will provide the permanent bonding. If the anchors are made of non-absorbable material they may remain where located. A plurality of such paired fused-scar bonds may be generated, at the surgeon's discretion, to ensure adequate support for the repaired vagina. The apparatusand method can be readily adapted to similarly effect deliberate, local, beneficial bonding between other adjacent living tissues in a patient.

A method of maintaining the structure of an opening in the anterior or posterior capsule formed by a capsulorhexis whereby a device is inserted into opening in the anterior or posterior capsule, the device having a main body including a peripheral portion and an opening therethrough, wherein the peripheral portion engages with the inside peripheral edge of the opening in the anterior or posterior capsule, wherein the device is inserted into the opening in the anterior or posterior capsule after an intraocular lens has been inserted into the capsular bag of an eye during cataract corrective surgery.

Improved devices, systems, and methods for planning cataract surgery on an eye of a patient incorporate results of prior corrective surgeries into a planned cataract surgery of a particular patient by driving an effective surgery vector function based on data from the prior corrective surgeries. The exemplary effective surgery vector employs an influence matrix which may allow improved refractive corrections to be generated so as to increase the overall efficacy of a cataract surgery by specifying one or more parameters of an intraocular lens (IOL) to be implanted during the cataract surgery.

A spinal deformity correcting instrument is made of shape memory alloy capable of being implanted into the spinal column of a human body, and comprises a hook, universal heads and longitudinal bars. The universal heads and the hook are integrated, the universal heads on two sides of the hook are respectively arranged on a left shoulder and a right shoulder of the hook and are hollow cylinders, U-shaped grooves are arranged on the cylinders, and threads are arranged on inner side surfaces of the U-shaped grooves; the longitudinal bars are solid cylinders and are fixedly placed in the U-shaped grooves of the universal heads, and diameters of the longitudinal bars are matched with sizes of the U-shaped grooves arranged on the universal heads; and the hook is arched, bent hooks are arranged at two ends of the hook, and a longitudinal groove is arranged on the arched top of the hook. During usage, a doctor can operate the spinal deformity correcting instrument on a transverse process or vertebral plate without implanting a pedicle screw into the human body or opening the spinal canal of the human body, advantages of the bent hooks, the longitudinal bars and the universal heads which are made of the memory alloy can be sufficiently played, complicated surgical operation is simplified, surgical risks are greatly reduced, and the spinal deformity correcting instrument can be widely applied to various spinal deformity correcting surgeries and can be easily popularized in primary hospitals.

The invention relates to a planning device for generating control data, a treatment device for refractive ophthalmic surgery and a method for generating control data for such a treatment device which enables better Complementary refractive correction. In this case, the planning device includes a calculation unit for determining the corneal cutting plane for the retreatment, wherein the calculation unit is designed to take into account changes in the thickness of the epithelium, which are mainly caused by previous treatments, during the calculation. .

A system and method are provided for an ophthalmic surgical procedure to provide a refractive correction for an eye. Specifically, the procedure is indicated when the desired refractive correction “dreqd” exceeds the capability of a correction achievable when corneal tissue is only ablated. In accordance with the present invention, an optimized refractive correction “d1” is accomplished by the ablation of corneal tissue (e.g. by a PRK or LASIK procedure). The optimized correction is then followed by a complementary refractive correction “d2” wherein stromal tissue is weakened with Laser Induced Optical Breakdown (LIOB). Together, the optimized refractive correction (ablation) and the complementary refractive correction (LIOB) equal the desire refractive correction (dreqd=d1+d2).
