摘要： PROBLEM TO BE SOLVED: To provide a surgical stapler having a longer distance capable of sewing than a conventional one, easy turning operation of a cam-operated lever, and capable of miniaturizing, and to provide its operation unit. SOLUTION: In the surgical stapler 10, a straightly moving stroke of a slide cam 23 is longer than that of a gear shaft 53 of the rolling gear 50 pivotally supported to one place, and the distance capable of sewing becomes longer. Furthermore, because the distance capable of sewing becomes longer by moving the rolling gear 50 itself, the power transmission efficiency is not fallen as in the case of increasing number of stages of the gear. In addition, the gear is attempted to miniaturize as compared with the diameter of a big gear 52 enlarged to a small gear 51. Namely, longer sewing is enabled by easy turning operation of the cam-operated lever 35, and the surgical stapler 10 can be miniaturized more than before. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供一种具有比常规缝纫更长距离的手术吻合器，容易地转动操作操纵杆并且能够小型化并提供其操作单元。解决方案：在外科缝合器10中，滑动凸轮23的直线移动的行程比可枢转地支撑在一个位置的滚动齿轮50的齿轮轴53的行程长，并且能够缝制的距离变长。此外，由于通过移动滚动齿轮50本身而能够缝制的距离变长，所以与齿轮级数增加的情况相比，传动效率不会下降。此外，与扩大为小齿轮51的大齿轮52的直径相比，尝试将齿轮小型化。即，通过容易地旋转操作杆35来进行更长的缝合，并且外科缝合器10可以比以前更小型化。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a surgery apparatus capable of enhancing force of holding or cutting an object to be operated comparing to that of a conventional apparatus. SOLUTION: According to a stapler 10, an axial force of a slide member 16 can be converted to turning force of the movable clamp 15 amplifying more than that of the the conventional ones, because a toggle mechanism for converting the axial force of a slide member 16 to the turning force of the movable clamp 15 is constituted of a pair of toggle links 41, 42 and an acting force providing link 44. Thereby, the force for holding or cutting the object to be operated between movable clamp 15 and an immobile clamp 17 can be enhanced compared to that of the conventional ones. Furthermore, the constitution of the distal end portion of a base member 14 can be made compact because the pair of toggle links 41, 42 are arranged in a direction (a longitudinal direction) in which the base member 14 extends.

摘要： PROBLEM TO BE SOLVED: To provide a disposable surgical instrument for preventing reuse and its reuse preventing method. SOLUTION: In using a bipolar tweezers 10 in a surgical operation, tab operation is carried out to perform hemostasis and/or incision of an affected part with arc generated between the tips of conductive members 14, 14. When heating sterilization treatment is conducted after the surgical operation, a resin member 13 is softened and deformed so that the paired conductive members 14, 14 are shifted from each other to disable generation of arc. Thus, the bipolar tweezers 10 can be prevented from being accidentally reused. Further, even if the bipolar tweezers 10 is heat-treated for discarding not for the purpose of use, the appearance is eroded so that the third person can be made to easily recognize the impossibility of reuse.

摘要： PROBLEM TO BE SOLVED: To provide a surgical stapler and its operating unit capable of performing an operation of a clamping body for clamping suture objects with force smaller than the conventional one. SOLUTION: This surgical stapler 10 is constituted of a toggle mechanism 34 converting the rotational movement of an opening/closing operation lever 33 into a linear movement of a linear movement body 16 by a pair of toggle links 41 and 42 and an orthogonal link 44 so as to relatively strongly push the linear movement body 16 to the side of the operating part 11 by relatively small operating force to the opening/closing operation lever 33. This constitution can perform an operation of clamping the suture objects 90A and 90B between a movable clamping body 15 and a stationary clamping body 17. The pair of toggle links 41 and 42 are formed into approximately same lengths to efficiently convert the rotational operating force of the opening/closing operation lever 33 into the linear movement driving force of the movable clamping body 15.

摘要： PROBLEM TO BE SOLVED: To provide a surgical instrument and a hand piece making it easy to perform an operation or process on areas that the difficult to handle with conventional surgical instruments and hand pieces of the type causing vertical vibration. SOLUTION: The surgical instrument 10 achieves hemostasis using frictional heat by pressing an affected area against a side face of a shaft-like tool 12 as the side face of the tool 12 vibrates in a direction perpendicular to an axial direction, because vibration transmitted to the tool 12 is torsional vibration. In this case, an end face of the tool 12 without axial vibration does not collide against the affected area, reducing stimuli to the affected area as compared with conventional surgical instruments of the type causing vertical vibration. Thus, hemostasis can be achieved for such affected areas as are difficult to handle with conventional surgical instruments of the type causing vertical vibration.
