Devices and methods are disclosed for achieving hemostasis in patients who have received skin-penetrating wounds to the periphery, including the head, arms, and legs. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery, or military setting. The devices utilize fluid impermeable barriers surrounded by exterior dams and pressure to achieve tamponade and hemostasis, primarily by exertion of force to hold the dams against the skin surrounding a wound. The devices are capable of serving as carriers for thrombogenic, antimicrobial or antipathogenic agents. The devices do not require the use of adhesives to work as they are attached to the patient using mechanical locking devices. Peripheral haemostatic packing devices include optional adhesive hemostatic barriers to attach at least a portion of the device to the skin or to assist with initial coupling of a hold-down strap to another strap using a more secure mechanical lock. The peripheral hemostatic packing system does not completely surround the extremity having the wound and therefore do not cause a tourniquet effect. The peripheral hemostatic packing system preferably is held against the skin surrounding a wound by a force that is generally unidirectional and substantially perpendicular to the plane in which the skin of the wound resides.

Devices and methods are disclosed for achieving hemostasis in solid visceral wounds. Such devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to the abdominal viscera. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts are pulled tight to bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts overcome the limitations of sutures that are currently used for the same purposes. The bolts come in a variety of lengths and diameters. Since the bolts are flexible, the curvature may be adjusted by the surgeon. The devices are flexible, bendable, and conformable in their wet or dry state. They can be used either straight or through a broad range of curvatures to suit the needs of various pathologies. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts may be placed and removed by open surgery or laparoscopic access.

Devices and methods are disclosed for achieving chest drainage in humans or other animals. Chest drainage is often required following traumatic injury or surgery. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting. The devices utilize a chest tube with a cutting distal end and a central blunt trocar. The blunt trocar or obturator shields the sharp cutting distal end of the chest tube until controllably retracted. Once the blunt trocar or obturator is retracted, the chest tube is advanced out through its sterile, protective package and into the patient. The blunt trocar is advanced back into its position to shield the sharp tip of the chest tube during patient insertion. The chest tube also includes a hold-down mechanism that is created by an adhesive seal to the patient's chest and ribbons or straps that are wrapped around the chest tube once it is correctly positioned. The straps include adhesive ends to grip the chest tube once the straps are in place.

Hepatic ischemic reperfusion injury is a major complication of liver transplantation, resectional hepatic surgeries, trauma surgery and shock. Disclosed herein are methods for the prevention and treatment of ischemia and reperfusion injury with the administration of sulfatides. Also disclosed herein are methods of preventing and treating hepatic reperfusion injury by administering an amount of a sulfatide to the body of a patient effective to reduce or prevent the symptoms of the injury.

The invention discloses a Fourier-Mellin domain based two-dimensional/three-dimensional image registration method, which belongs to the field of medical image registration. The method can be applied to bone trauma surgery navigation systems, and used for associating a preoperative planning with intraoperative three-dimensional images so as to achieve the purpose of guiding an operation. The method is implemented through the following steps: by using the scale of images in a Fourier-Mellin domain, rotating and translating the coupling degree among invariably-separated to-be-optimized parameters; according to an estimated out-of-plane rotation parameter, calculating an in-plane rotation parameter; estimating the distance between an X ray and a three-dimensional image; estimating the distance between the three-dimensional image and a receiver; and calculating an in-plane translational sequence so as to carry out registration. The two-dimensional/three-dimensional image method disclosed by the invention lays a foundation for the reconstruction of preoperative data in intraoperative three-dimensional images.

Devices and methods are disclosed for achieving hemostasis in solid visceral wounds. Such devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to the abdominal viscera. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts are pulled tight to bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts, or soft tissue rivets, overcome the limitations of sutures that are currently used for the same purposes. The bolts come in a variety of lengths and diameters. Since the bolts are flexible, the curvature can be adjusted by the surgeon. The devices are flexible, bendable, and conformable in their wet or dry state. They can be used either straight or configured in a broad range of curvatures to suit the needs of various pathologies. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts may be placed and removed by open surgery or laparoscopic access. The bolts can be placed into tissue where both sides of the bolt are exposed, or the bolts can be placed blindly into tissue where the bolt does not protrude out of the tissue at its distal end.
