Abstract: A multi-functional handle manipulates a medical instrument and includes a body capable of being gripped by a hand of a user and further capable of being in communication with the medical instrument. In non-limiting exemplary embodiments, the handle may include one or more of a first trigger assembly, a second trigger assembly and a third trigger assembly. Non-limiting exemplary embodiments also include one or more of a primary digit-receiving member, a secondary digit-receiving member, and a tertiary digit-supporting member for facilitating ergonomic operation of the handle. The actuation arm actuates the medical instrument independently from movement of the primary digit-receiving member wherein the primary digit-receiving member can be selectively displaced between alternate orientations relative to a position of the body and relative to a position of the actuation arm, respectively, without affecting manipulation of the medical instrument.

Abstract: A multi-functional handle manipulates a medical instrument and includes a body capable of being gripped by a hand of a user and further capable of being in communication with the medical instrument. In non-limiting exemplary embodiments, the handle may include one or more of a first trigger assembly, a second trigger assembly and a third trigger assembly. The body may also include a first portion and a second portion coupled thereto such that the second portion is displaced relative to the first portion. At least one of the first portion, second portion and first trigger assembly is capable of manipulating the medical instrument. Non-limiting exemplary embodiments also include one or more of a primary digit-receiving member, a secondary digit-receiving member, and a tertiary digit-supporting member for facilitating ergonomic operation of the handle.

Abstract: A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a housing with an opening formed in line with an axis of the housing. The cap assembly also includes a variable opening flexible sealing gland having a stack of valve body sections each including a valve extension extending from a valve ring and having a valve opening and a slit extending between a valve opening and the valve ring. The combination of the individual valve body sections forms a substantially conically shaped iris diaphragm portion of the sealing gland. The iris is positioned to individually and separately receive elongate tools so that when any one of the elongate tools is positioned through the valve opening, a seal is maintained between peripheries of the seal gland surrounding the iris and outer peripheries of the inserted elongate tool.

Abstract: An optical safety trocar and method of use thereof, wherein a shield deploys to guard against accidental tip contact and potential injury therefrom, and wherein an optical tip facilitates visualization of the trocar advancement into a body cavity, such that the visualization not only precludes blind penetration in order to avoid inadvertently injurious positioning of the tip, but enables identification of any unintentional and otherwise undetectable damage.

Abstract: A surgical device having a trocar, a handle with hand-gripping portion adjacent a proximal end, a cannula-interface portion adjacent a distal end and having a recess therein, and an instrument opening extending into a medial portion and through the recess in the cannula-interface portion. The device also includes an instrument seal having an opening therein, positioned in the medial portion of the handle adjacent the instrument opening, a tubular trocar having a proximal end portion adapted to be positioned in the recess of the cannula—interface portion, adjacent the instrument seal and extending outwardly therefrom, and a cannula adapted to receive at least portions of the tubular trocar there through and having a proximal end portion adapted to be received in the recess of the cannula-interface portion of the handle and extending outwardly therefrom so that the handle supports the combination of the cannula and trocar when positioned in the recess.
