摘要： A stability assembly for a trocar cannula includes a conical stability member, a base, and a cannula retention member. The base has a passage defining an inner surface, and a constriction in the passage. The cannula retention member is rotatable within the passage, and advancement of the cannula retention member over the constriction reduces the inner diameter of the passage to restrain a cannula in the passage. Various latch mechanisms including interface surfaces on the base and the cannula retention member can be used in the stability assembly to secure the stability assembly around a cannula. Various conical stability members can be used in the stability assembly.

摘要： The invention is directed to a pair of laparoscopic scissors, comprising a pair of blades connected at a pivot, each of the blades having a length, a tip portion, a body portion, an outer surface, an inner surface and a cutting edge, the cutting edge forming an angle with the outer surface along the length of the blade such that tension during a cutting operation at the tip portion is about the same as tension at the body portion during the cutting operation. The angle formed may be greater at the tip portion which continuously decreases over the length of the blade. The tip portion may have a first body thickness and the body portion may have a second body thickness different from the first body thickness. During the cutting operation, the blades progressively move over each other to provide a point contact along the cutting edges. The blades may be thickened in a number of locations and combinations including: (1) one blade could be thicker than the other to force the opposing blade to flex; (2) both blades could be thicker at the body portions to give more strength when cutting staples; (3) each blade could be thickened on one side or the other to stiffen certain locations; and (4) the tips of each blade could be thicker than the body portions to provide increased tension at the tips. In another aspect of the invention, a process of manufacturing the pair of scissors of the invention is disclosed, comprising the steps of form grinding the blades into a desired shape from a pre-hardened block of material, and sharpening the cutting edges of the blades. The blades may also be formed through other processes including wire EDM, laser cutting, waterjet cutting, machining, cast or metal injection molding, and other independent profile manufacturing processes. The manufacturing process of the invention is beneficial in that each profile can be accurately controlled, and the parts will be exact every time.
摘要翻译：本发明涉及一对腹腔镜剪刀，包括一对在枢轴处连接的刀片，每个刀片具有长度，尖端部分，主体部分，外表面，内表面和切割边缘，切割刃沿着刀片的长度与外表面形成一角度，使得在切割操作期间在尖端部分的切割操作期间的张力与主体部分处的张力大致相同。形成的角度可能在尖端部分处大于叶片长度上连续减小的角度。尖端部分可以具有第一本体厚度，并且主体部分可以具有不同于第一主体厚度的第二主体厚度。在切割操作期间，叶片逐渐地彼此移动以沿着切割边缘提供点接触。叶片可以在多个位置和组合中增厚，包括：（1）一个叶片可以比另一个叶片更厚以迫使相对的叶片弯曲; （2）当切割订书钉时，两个叶片在主体部分可以较厚，以提供更大的强度; （3）每个叶片可以在一侧或另一侧增厚以加固某些位置; 和（4）每个叶片的尖端可以比主体部分更厚，以在尖端处提供增加的张力。在本发明的另一方面，公开了一种制造本发明的一对剪刀的方法，包括以下步骤：从预硬化的材料块将刀片成型为期望的形状，并且磨削刀片的切割刃。刀片也可以通过包括线切割，激光切割，水刀切割，机械加工，铸造或金属注射成型以及其它独立轮廓制造工艺的其它工艺形成。本发明的制造方法的优点在于，可以精确地控制每个轮廓，并且每个部件将每次都精确。

摘要： A surgical instrument comprising an elongate tube extending along an axis includes an actuation mechanism; a first jaw spine; and a second jaw spine the second jaw spine pivotally connected to the first jaw spine at a common pivot pin to open and close the jaw spines in response to movement of the actuation mechanism. 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： Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.
