摘要： The invention is directed to a pin and slot design where the driving slots are moved from the tips to the actuation rod in one aspect of the invention. As a result, the back end of each blade or tip can be dramatically reduced in area so that during full deflection, very little or no part of the blade or tip extends beyond the outside diameter of the shaft. This ensures that nothing catches on the blades or tips during grasper use and the shrink tubing found on the scissors would not be deformed. This can be done because the area for the slots is not needed. Moreover, the usable area for the drive slots on the blade or tip of the actuation rod is maximized to the overall diameter of the outer tube or shaft which provides additional leverage to the blades or tips. In addition, the depth of each slot can be varied such that during actuation, increased tension can be put on the blades or tips throughout the cut. More specifically, the surgical instrument of the invention comprises an elongate tube extending along an axis including an actuation rod coaxially slidable within the elongate tube, a first tip including a first pin formed on a proximal end surface of the first tip, and a second tip including a second pin formed on a proximal end surface of the second tip, the second tip pivotally connected to the first tip at a common pivot pin operably connected to the elongate tube to open and close the tips in response to movement of the actuation rod. The actuation rod has a slot to accept the pins of the first and second tips, the slot has camming surfaces for the pins to slide within the slot, and the proximal ends of the tips extend minimally outside the diameter of the elongate tube during actuation of the tips.
摘要翻译：本发明涉及一种销和槽设计，其中驱动槽在本发明的一个方面中从尖端移动到致动杆。结果，每个叶片或尖端的后端可以大大减小面积，使得在完全偏转期间，叶片或尖端的很少或没有一部分延伸超过轴的外径。这样可以确保在抓紧器使用过程中没有抓住刀片或尖端，并且剪刀上发现的收缩管不会变形。这可以做到，因为不需要插槽的区域。此外，用于驱动槽上的驱动槽或致动杆顶端的可用面积最大化到外管或轴的总直径，这为叶片或尖端提供额外的杠杆作用。此外，每个槽的深度可以变化，使得在致动期间，可以在整个切割中的刀片或尖端上增加张力。更具体地说，本发明的手术器械包括沿着轴延伸的细长管，该细长管包括在细长管中同轴滑动的致动杆，包括形成在第一末端的近端表面上的第一销的第一末端和第二末端包括形成在所述第二末端的近端表面上的第二销，所述第二末端以可操作地连接到所述细长管的共同枢轴销枢转地连接到所述第一末端，以响应于所述致动杆的移动来打开和关闭所述末端。致动杆具有用于接纳第一和第二尖端的销的槽，槽具有用于销在槽内滑动的凸轮表面，并且尖端的近端在致动提示。

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.
摘要翻译：本发明涉及一种外科器械，其包括沿轴线延伸的细长管，所述细长管包括可操作地连接到所述凸轮杆的凸轮杆和致动机构，所述凸轮杆具有凸轮销和凸轮凸轮; 具有第一凸轮槽，第一内部凸轮表面和第一外部凸轮表面的第一颚骨脊; 以及具有第二凸轮槽，第二内部凸轮表面和第二外部凸轮表面的第二夹爪，所述第二夹爪枢转地连接到与所述细长管可操作地连接以打开和关闭的公共枢轴的所述第一夹爪颚爪响应于致动机构的移动而刺入。凸轮销沿着第一和第二内部凸轮表面骑行，并且当凸轮杆向近侧移动时操作以闭合颚骨棘爪。当凸轮杆向远侧移动时，凸轮突起可骑在形成在相应的第一和第二爪脊的近侧上的第一和第二外部凸轮表面上，并且操作以打开颚骨。本发明的特征是每个颚骨上的一个凸轮表面可以有助于闭合颚骨棘爪，而每个颌骨上的另一个凸轮表面可以有助于打开颚骨。每个颚骨上的这两个凸轮表面可以被广泛地分开。颚棘可以由金属材料形成，并用无创伤的塑料材料包覆成型。通过将塑料包覆成型到金属脊上，无损伤的外表面可以由塑料材料以高度的细节形成。
