Abstract: A needle or cylindrical element position lock includes a disposable template assembly having front and back templates halves which define an array of close-fitting through-holes to guide needles therethrough. A series of lock slides locks the positions of columns of needles positioned within the template. Each lock slide locks the position of one or more needles inserted into one or more series of the through- holes in the template, with a preferred embodiment locking two series of needles. Each lock slide has the capability of locking one or more series of needles inserted into through-holes in the needle guide template by an axial motion applied by a lock lever or cam. When the lock slide is moved axially, a locking function is provided by a wedge/clamp which engages an inserted needle. For a typical template arrangement, six lock slides are used to lock twelve columns of needles inserted into through-holes in the template assembly.

Abstract: An electrosurgical hemostatic instrument including a curved end effector. A preferred embodiment of the invention provides a bipolar endoscopic clamping, coagulation and cutting device. In this device, a substantially straight, axially flexible knife is used to cut tissue grasped by the jaws of the end effector. The end effector includes a knife channel which is wider than the knife. The knife may include sacrificial contact points adapted to contact the walls of the knife channel as the knife moves through the channel, protecting the cutting edges of the knife blade from damage.
