    摘要： The invention is directed to a surgical instrument comprising an elongate tube extending along an axis including a camming rod and an actuation mechanism operably connected to the camming rod, the camming rod having a camming pin and a camming projection; a first jaw spine having a first cam slot, a first interior camming surface, and a first exterior camming surface; and a second jaw spine having a second cam slot, a second interior camming surface, and a second exterior camming surface, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin operably connected to the elongate tube to open and close the jaw spines in response to movement of the actuation mechanism. The camming pin rides along the first and second interior camming surfaces and operates to close the jaw spines when the camming rod is moved proximally. When the camming rod moves distally, the camming projection rides on the first and second exterior camming surfaces formed on the proximal sides of the respective first and second jaw spines and operates to open the jaw spines. A feature of the invention is one camming surface on each jaw spine can facilitate closing the jaw spines while the other camming surface on each jaw spine can facilitate opening the jaw spines. These two camming surfaces on each jaw spine can be widely separated. The jaw spines can be formed of a metallic material and are overmolded with an atraumatic plastic material. By overmolding the plastic onto the metal spine, an atraumatic outer surface can be formed of the plastic material along with a high degree of detail.

    摘要： A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE). With the process of the invention, the heat of the molten gel at its molding temperature is transferred to the surface of the LDPE mold so as to melt a thin layer of the LDPE. The mold may comprise a mold base having a plurality of mold holes forming a plurality of mold cavities, each of the mold holes comprising an axial pin to mold an axial hole through a center of the gel, an LDPE cylinder providing a predetermined inside diameter for the mold, and an LDPE disc mounted on the axial pin and disposed at the bottom of each mold cavity in the mold base. The process may further comprise the step of dabbing the gel in a low-friction powder such as polytetrafluoroethylene (PTFE) and a lubricant. The mold may further comprise a mold top disposed axially of the mold base and comprises a plurality of holes forming a plurality of cavities, each of the mold top holes is adapted to receive the LDPE cylinder, and a second LDPE disc disposed at the top of each mold cavity of the mold top.

    摘要： The invention is directed to a method for manufacturing a thin-wall, single-piece optical obturator having an integral tip and shaft. The invention includes providing an injection mold defining a mold cavity having a core pin positioned within the mold cavity. The mold includes at least one gate and multiple core support pins between the core pin and the mold cavity walls, with at least one primary core support pin positioned on a side opposite the at least one gate. The method also includes injecting a transparent molten polymeric material having high flow properties into the injection mold such that the polymeric material flows between the surface of the mold cavity and the core pin. The core support pins substantially prevent the core pin from shifting while the polymeric material is injected into the mold. The high-flow nature of the polymeric material allows for complete filling of the mold cavity.

    摘要： A surgical access device comprises an elongate shaft with a bladeless tip at the distal end. The bladeless tip has an outer surface with a proximal portion, a distal portion, and an intermediate portion. In a cross section in the proximal portion, the outer surface defines a circle. In a cross section in the intermediate portion, the outer surface defines a shape having a length greater than a width. The outer surface has first and second opposing surface portions of the shape that are generally aligned with the length. In a cross section in the distal portion, the outer surface defines a circle. In progressive proximal cross sections in the distal portion, the circle expands. In progressive proximal cross sections in the intermediate portion, a ratio of the width of the shape to the length of the shape increases and the first and second opposing surface portions are more arcuate.

    摘要： A surgical obturator comprising an elongate shaft extending along an axis between a proximal end and a distal end includes a bladeless tip disposed at the distal end of the shaft. The tip has a blunt point and a pair of shorter side surfaces separated by a relatively longer pair of opposing surfaces to form in radial cross-section a geometric shape that has a longer length and relatively narrower width. The side surfaces and opposing surfaces terminate in end surfaces located proximally from the blunt point. The end surfaces extend radially outwardly from opposite locations of the outer surface. A conical surface facilitates initial insertion of the obturator and the geometric shape facilitates separation of consecutive layers of muscle tissue having fibers oriented in different directions and provides proper alignment of the tip between the layers of muscle.

    摘要： A surgical obturator comprising an elongate shaft extending along an axis between a proximal end and a distal end, and a bladeless tip disposed at the distal end of the shaft having a conical surface forming proximally into an outer surface, the outer surface extending distally to a blunt point and having a pair of side sections. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. The conical surface facilitates insertion of the obturator with a reduced penetration force and minimizes tenting of the body wall. The conical surface further facilitates separation of different layers of the body wall and provides proper alignment of the tip between the layers. The surgical obturator may be constructed from a disposable or reusable material such as a metal or an autoclavable polymer. While certain embodiments have been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope thereof as defined by the following claims.

    摘要： The present invention relates to an apparatus that controllably allows the relative rotation between structures, such as a gimbal and a structure to which it is mounted. According to one aspect, the apparatus includes a twist capsule assembly with internal stop mechanisms that controllably prevents the amount of clockwise and counterclockwise rotation with respect to a rotation axis. According to another aspect of the invention, by limiting the amount of relative rotation, other means of communicating power and signals between the structures can be used, thus avoiding or reducing the limitations imposed by conventional slip ring assemblies. According to yet another aspect, the invention includes techniques and structures for allowing conventionally shielded cables and wires to be used in place of slip rings, while allowing for rotation between structures, thus even further improving the communication of power and signals between structures.
