摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack. The instrument further has a manually actuatable retraction system that does not require the use of additional springs or other mechanisms to generate retraction forces which must be overcome when generating the forces necessary to fire the device. In various embodiments, the retraction system provides a visual indication to the surgeon as to how far firing has progressed.

摘要： Apparatuses and methods for safely inserting of a catheter into a patient and the use of a solid needle. An exemplary apparatus of the present invention includes a needle shaft, which is coupled to a solid needle tip. The needle shaft includes a first end, a second end, and a first dimension. The solid needle tip includes a sharp end and a blunt end, a groove, and a second dimension. The second dimension is greater than the first dimension such that a juncture, which is a step up from the first end, is formed when the needle shaft is coupled to the solid needle tip. The groove runs axially along a surface of said solid needle tip and extends from said sharp end to said blunt end. A catheter is disposed about the needle shaft and the solid needle tip with the solid needle tip protruding from an edge of the catheter. A connector is used to couple the catheter to a safety container, which is partially disposed within a body. The safety container is designed to trap the solid needle tip therein after the solid needle tip retracts into the safety container.
