A method of locating and identifying, during surgery, target regions within a body intended for excision of suspect tissue and/or removal of diseased organs or foreign objects, resides in implantation within the body proximate the suspect tissue or object prior to surgery of one or more passive integrated transponder tags and, at the time of and/or during surgery, scanning of the body with a radio frequency scanner or reader that activates the tag or tags and provides the surgeon with one or more signals indicative of the approximate location and unique identification of each of the tags, thereby to aid the surgeon in performance of the surgery. Verification of the success of the surgical procedure is obtained following surgery by scanning the site for absence of the tag or tags and/or by scanning the excised tissue for presence of the tag or tags.

The invention belongs to the computer aided surgical technique and maxillofacial plastic medical treatment equipment field and relates to a computer simulation method for predicting soft tissue appearance change after a maxillofacial bone plastic surgery. The method comprises the following steps that: spiral CT scanning is performed on the maxillofacial of a patient before the surgery; data are led into maxillofacial surgery design simulation software, namely, CMF-pre CADS, so that a three-dimensional maxilla and skin surface model is re-constructed; a bone segment is reset/shifted to a preliminary location; and the similarity of a pre-surgery prediction model and a post-surgery true appearance is judged through comparison through Geomagic software. With the method adopted, the post-surgery appearance and stomatognathic system functions can be recovered excellently; the appearance of soft tissues are symmetrical, harmonious and beautiful; the post-surgery satisfaction degree of the patient reaches 95%; the effects of the plastic surgery are stable; and long-term satisfaction is also very high.

A threaded cap or c-clip that attaches to a spinal rod or bone screw. Such a threaded cap or c-clip prevents slippage of the spinal system assemblies along or off their rods or bone screws during intra- or post-operative periods.

An adjustable drill guide is provided that can be used to deliver a cross pin at a distance near the entrance to the femoral bone tunnel during ligament surgery. The cross pin positioned at the joint line, or tunnel opening, compresses and secures the graft within the bone tunnel, thereby preventing the graft from swaying back and forth post surgery when the joint is in motion. The adjustable drill guide assembly comprises a guide frame that includes an arm portion and a base portion that extends transversely to the arm portion. A rod member connects to the base portion for extending into the hone tunnel of the bone. Also included is a guide member configured for connection to the arm portion. The guide member is configured to be in moveable and lockable disposition along a length of the arm portion.

An expandable surgical retractor for minimally invasive surgical applications is disclosed. The expandable retractor, preferably in the form of an inflatable balloon retractor, is inserted in a surgical corridor and expanded to the desired size and shape. The retractor of the present invention is amenable to many shapes including cylindrical, conical with the base at the depth of the corridor, hourglass, and crescent and are dictated by the surgeon's needs. Cooling of the retractor allows the retractor to maintain the expanded characteristic. The expanded relatively rigid retractor provides an ideal corridor for surgical applications. In a preferred embodiment, a second retractor, of the invention, can be placed at a greater depth through the first placed retractor; the “telescoping” effect rapidly provides greater exposure with minimal manipulation. Following surgery, such retractor(s) can be removed in a manner that minimizes bleeding and tissue damage. One such method is reheating to soften and restore the retractor to its unexpanded size. Or, laterally placed perforations allow for fracturing of the retractor by bovie cautery, facilitating removal by “unzipping” the retractor.

In the present invention, Applicants demonstrate the effect of a biomembrane sealing agent on the development of chronic pain following tissue injury as well as acute pain in a model of acute inflammation. Applicants demonstrate the ability of this class of agents referred to as “biomembrane sealing agents” to reduce the severity of hyperalgesia and allodynia following mechanical insult to the nervous system as well as their ability to reduce acute pain in a model of acute inflammation. Applicant describes the use of injectable or depot formulations of biomembrane sealing agent(s) for prophylactic treatment such as they could be administered after the insult (i.e. post-injury or post-surgery) but before the onset of acute or chronic pain. Alternatively, biomembrane sealing agents could be used to reduce the severity of acute or chronic pain after onset.

Resorbable polylactide polymer healing membranes and methods of their applications are disclosed. In a broad embodiment, the invention features methods for inducing proper tissue healing after an open heart surgery. In one embodiment, the methods includes a step of forming a patch with a healing membrane over the open pericardium to induce proper tissue healing and placement in other open heart surgery procedures to facilitate re-entry by the surgeon.

A method for reducing muscle atrophy in an individual undergoing orthopedic surgery, the method comprising administering to said individual a mixture of protein and non-protein nutrients for 4-7 days pre-surgery and for 10-21 days post-surgery. The protein dosage is 15-30 g, of which 17-25% is leucine, 23-35% is 1-glutamine, 10-15% is 1-arginine and 1-2% is cysteine. The protein nutrients are derived from a combination of commercially available proteins and the appropriate free amino acid. The non-protein nutrients are a mono or disaccharide in the amount of 15-30%, N-acetyl-cysteine in the amount of 1-15% and the antioxidant Vitamin C.

A post-surgery bra includes an aperture appropriately sited to so that tubes from a boost-treatment device or drain implanted in a wearer of the bra protrude therethrough. The post-surgery bra includes a fixation element for immobilizing the tubes of the boost-treatment device that protrude through the aperture. In some embodiments, the post-surgery bra also includes a retaining ring, which is coupled to the bra below the breast cup nearest to the aperture and which is openable and closeable for engaging and securing a loop of material that extends from the collection bulb of the drain.

The invention discloses an anatomy reconstruction skull patch filling a skull defect opening part. An edge shape of the patch is identical to an edge shape of the skull defect opening; a patch stereoscopic structure is identical to a skull defect stereoscopic structure; and the patch is made of degradable biological hard material. The invention further discloses an anatomy reconstruction skull patch quick manufacturing method. The patch manufacturing method can produce patches with high accuracy, great coupling property, great repairing exactness, firmness and safety as well as reliability; great patch structure and biocompatibility can be achieved; surgery cost can be reduced and time can be shortened; and post-surgery complications can be reduced.

A sling apparatus and method of treatment for stress urinary incontinence, prolapse, and the like. The apparatus and method may comprise a support material of any construction known within the art which is temporarily held in position by at least one tension member. A tension member may be attached to an end of the support material and the remaining free end of the tension member may then be releasably fastened to a fixation device at or above the level of the skin. Both the tension member and the fixation device may have incremental and/or measurable indicia disposed thereon to provide for either incremental increases or decreases in support material tension post-surgery. Upon support material natural fixation, the tension member may be cut at or below the level of the patient's skin. The tension member may comprise either permanent or bio-absorbable material.
