摘要： A dental burr has an axis of rotation and a cooling water passage extending therethrough in coaxial relation to the dental burr. The cooling water passage opens to a front end face of the dental burr, and this opening in the front end of the dental burr is disposed in an area including the axis of rotation of the dental burr. A dental handpiece for rotatably holding a dental burr includes a handgrip portion, a hollow head portion provided at a front end of the handgrip portion, and a cooling water passage. This cooling water passage extends along the handgrip portion,and opens at one end to a rear end of the handgrip portion while the other end thereof is connected to an internal space of the head portion. Part of the internal space serves as a passage for communicating the cooling water passage of the dental handpiece with the cooling water passage of the dental burr held by the dental handpiece.

摘要： In a medical stapler, an anvil is disposed in the vicinity of an opening in a casing, and is disposed in a path of movement of a ram. A foremost staple placed on the anvil is shaped through the cooperation of the advancing ram with the anvil in such a manner that a pair of legs of this foremost staple are moved toward each other. The anvil has a shaping surface disposed in opposed relation to the ram. This shaping surface is inclined relative to the path of movement of the ram in such a manner as to approach the ram progressively toward the distal end of the shaping surface.

摘要： A surgical stapler has a body capable of containing a plurality of staples in an aligned state; a ram provided inside said body, having a central concave portion and pressure armatures on both sides of the concave portion; an anvil that, when the armatures of said ram contact both sides of a crown of a staple, forces the center of the crown into the concave portion of the ram; and a trigger rotatably supported on the body so as to cause relative movement between the ram and the anvil. A moving member strikes another member so as to produce a sound or a sensation of impact after a staple sandwiched between the ram and the anvil is bent by the advance of the anvil into the concave portion of the ram and bending of the staple is completed.

摘要： A surgical staple has a base portion and a pair of leg portions respectively extending angularly from the opposite ends of the base portion. Each leg portion has at its distal end portion a first inclined surface and a second inclined surface extending from the first inclined surface to the distal end of said leg portion. The first and second inclined surfaces are inclined with respect to the axis of the leg portion. The angle between the first inclined surface and the axis of the leg portion is smaller than the angle between the second inclined surface and the axis of the leg portion. The second inclined surface terminates in a sharp edge at its distal end. For producing the surgical staple, a blade is moved toward each of the leg portions in inclined relation to the axis thereof to shear the leg portion, so that a smooth sheared surface and a coarse ruptured surface are formed on the distal end portion of the leg portion and arranged in this order toward the distal end of the leg portion. The sheared surface defines the first inclined surface whereas the ruptured surface defines the second inclined surface. A shearing member having the above blade serves to bend and shear the leg portions of the surgical staple.

摘要： A guide instrument for passing a medical needle with thread through or between body tissues has first and second shafts mounted to be pivotally movable to each other and is formed with, on the first shaft, a needle stand for making the needle with thread stand up and holding the needle with thread, a hole for guiding the thread, and a slit and with, on the second shaft, a needle receiver for receiving the needle when the shafts are made close while the needle with thread stands up at the needle stand. When the shafts 1, 2 are made close while the needle with thread stands up at the needle stand, the needle with thread passes through and between the body tissues and is engaged with the needle receiver. When the shafts are made open, the needle with thread while keeping the engagement with the needle receiver separates from the needle stand, and therefore, the needle with thread can be guided from the first shaft to the second shaft. Where a container for containing the needle with thread is formed in continuation with the needle stand on the parting faces of the first and second shafts, the container can prevent the needle with thread from dropping out, as well as can prevent the body tissues from being damaged by the needle, before the needle reaches an affected area at a time of ligation or suture.
摘要翻译： 用于使带有螺纹的医用针穿过身体组织之间的引导仪器具有安装成可枢转地彼此移动的第一和第二轴，并且在第一轴上形成有针架，用于使针具有螺纹架起来， 用螺纹夹持针头，用于引导线的孔和狭缝，并且在第二轴上具有用于当轴线在针架上竖立时使轴靠近时接收针的针头接收器。 当针1,2在针架处于针架的状态下靠近时，具有线的针穿过身体组织之间并且与针接收器接合。 当轴打开时，具有与针接收器保持接合的线的针与针架分离，因此具有线的针可以从第一轴被引导到第二轴。 当用针头容纳针的容器形成为与第一和第二轴的分离面上的针架相连时，容器可以防止具有线的针脱出，并且可以防止身体组织 在针结扎或缝合时针头到达受影响的区域之前被针损坏。

摘要： A dental handpiece includes an arm, and a hollow head formed on a distal end of the arm. The head has a nozzle projecting from an inner surface thereof. Cooling water, fed via a main coolant passageway of the arm, is injected from the nozzle. A generally cylindrical holder for supporting a dental burr is rotatably supported within the head. The cooling water injected from the nozzle passes through an auxiliary coolant passageway, formed axially through the dental burr, and is injected from a grinding portion of the dental burr. The dental handpiece also includes a pump mechanism for feeding the cooling water. Injected from the nozzle, into the auxiliary coolant passageway of the dental burr. The pump mechanism includes a screw mounted on the outer periphery of the nozzle, and a pump housing which is mounted on one end portion of the holder disposed close to the nozzle and surrounds the screw. The cooling water within the pump housing rotates in response to the rotation of the holder and the pump housing, and therefore is guided by the stationary screw to be fed into the auxiliary coolant passageway of the dental burr.
