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 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 method for forming a high flow insufflation needle stylet having distal, intermediate and proximal sections includes providing a flat sheet of metal and forming pilot holes in the sheet proximate opposed edges of the sheet. A profile of a flat pattern of the stylet is formed. The flat pattern has a proximal end, a distal end and a pair of substantially longitudinal edges. At least one support tab is positioned between the flat pattern and the sheet. The intermediate and the proximal sections of the stylet are progressively formed into a partial cylindrical shape with the proximal end being open and the longitudinal edges in the intermediate and proximal sections being positioned between about 90° and 180° apart. The distal section is progressively formed into a substantially cylindrical shape having a closed distal end. The stylet is trimmed from the sheet by cutting the at least one support tab.

摘要： The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a 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 and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers. The side sections include a distal portion and a proximal portion, the distal portion of the side sections being twisted radially with respect to the proximal portion of the side sections. The intermediate section includes a distal portion and a proximal portion, the distal portion of the intermediate section being twisted in a first radial direction and the proximal portion of the intermediate section being twisted in a second radial direction opposite the first radial direction.
摘要翻译：本发明涉及一种无插管套管针闭塞器，用于在插入穿过体壁时分离或分离身体组织。一方面，本发明的闭孔器包括沿着近端和远端之间的轴延伸的轴; 以及设置在所述轴的远端处并且具有大致锥形构造并具有外表面的无叶尖，所述外表面向远侧延伸到钝点，一对侧部具有共同的形状并且被至少一个中间体其中每个所述侧部分从所述钝点径向向外延伸，并具有沿所述轴向近端的渐进位置，并且所述轴的尺寸和构造用于容纳具有远端以接收所述身体组织的图像的光学仪器。通过这个方面，锥形配置便于分离身体组织的不同层，并提供顶层在层之间的适当对准。侧部包括远端部分和近端部分，侧部分的远侧部分相对于侧部部分的近端部分径向扭转。中间部分包括远端部分和近端部分，中间部分的远端部分在第一径向方向上扭转，并且中间部分的近端部分在与第一径向方向相反的第二径向扭转。
