Devices and methods for achieving hemostasis and leakage control in hollow body vessels such as the small and large intestines, arteries and veins as well as ducts leading to the gall bladder and other organs. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting, and most especially during damage control procedures. In such cases, the patient may have received trauma to the abdomen, extremities, neck or thoracic region. The devices utilize removable or permanently implanted, broad, soft, parallel jaw clips with minimal projections to maintain vessel contents without damage to the tissue comprising the vessel. These clips are applied using either standard instruments or custom devices that are subsequently removed leaving the clips implanted, on a temporary or permanent basis, to provide for hemostasis or leakage prevention, or both. These clips overcome the limitations of clips and sutures that are currently used for the same purposes. The clips come in a variety of shapes and sizes. The clips 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.

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 patients who have received skin-penetrating wounds to the body in regions such as the shoulder, pelvis, neck, or groin, where standard bandages are difficult to apply and where large blood vessels exist which can hemorrhage severely. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery, or military setting. The devices utilize packing pillows that are held in place by rigid structures that can cause the packing pillows to be brought into the wounds and be held in place while the packing pillows are inflated to fill the wounds, prevent bleeding, and tamponade hemorrhaging large blood vessels exposed therein.

A screw element includes a screw axis, a shank for inserting in a bone, and a drive portion for engaging a screw driver. The drive portion includes a first wall defining a first recess and a second wall defining a second recess. Drive grooves are formed in the first wall and extend parallel to the screw axis. The second wall extends axially from a free end portion of the screw element to the first wall and has an inner diameter that continuously increases from the first wall towards the free end portion. A plurality of guide grooves are formed in the second wall at circumferential positions corresponding respectively to circumferential positions of the drive grooves. The guide grooves extend further radially from the screw axis than the drive grooves and guide the screw driver from the free end portion of the screw element to the drive grooves.
