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： There are disclosed a method of and apparatus for grinding an elongated material for a suture needle. An elongated grinding tape is reciprocally moved in its longitudinal direction, and simultaneously the material is pressed against the grinding tape in such a manner that the material is disposed substantially perpendicular to the longitudinal direction of the grinding tape and is inclined relative to one face of the grinding tape, thereby grinding the material to form a cutting edge on at least one side edge of a grounded surface of the material. The grinding apparatus includes a mechanism for reciprocally moving the grinding tape in opposite directions along the longitudinal direction of the grinding tape, a mechanism for transferring the grinding tape in a predetermined one of the opposite directions along the longitudinal direction of the grinding tape, a tape support member, and a mechanism for supporting the material and for pressing the material against that portion of the grinding tape positioned at a support surface of the tape support member. A suture needle includes at least one ground surface, and a pair of cutting edges formed respectively on opposite side edges of the ground surface. The ground surface has grinding traces which extend perpendicular to an axis of the suture needle, and the pair of cutting edges are in generally the same condition from a microscopic point of view.

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.

摘要： In producing the surgical staple, a cutting edge is moved toward each of the leg portions of the wire from which the staple is formed in inclined relation to the axis of the leg portion to shear the leg portion, the leg portion being set on a receiving surface. A smooth sheared surface and a coarse ruptured surface are formed in order on the distal end portion of the leg portion toward the distal end of the leg portion. A shearing member having the cutting edge above serves to bend and shear the leg portions of the surgical staple.

摘要： There is disclosed a surgical stapler. An anvil is mounted on a distal end portion of an elongated body of the stapler. A guide member supports a number of staples disposed in contiguous relation to one another. The staples are urged toward the anvil by an urging mechanism. A ram is mounted on the body for movement along the longitudinal axis of the body. A lever is pivotally mounted on the body, and the pivotal movement of the lever is converted into a rectilinear movement of the ram by a motion converting mechanism. The ram, when advanced, cooperates with the anvil to deform the staple disposed in a path of movement of the ram. In order to achieve a lightweight and small-size construction of the stapler, the lever is pivotally connected at its proximal end to the proximal end portion of the body so that the lever is pivotally movable toward and away from the body, and a distal end portion of the lever serves as a manipulating portion. A mid portion of the lever spaced apart from the manipulating portion acts on the motion converting mechanism. Also, in order to achieve the above purpose, a guide passage for guiding an urging member of the urging mechanism has a curved portion, and the urging member has a flexible portion which can be guided by the curved portion.

摘要： An apparatus for attaching an end of a suture to an axially extending bore formed in a proximal end of a surgical needle. At least one of a pair of staking dies is movable toward and away from the other. A proximal end face of the surgical needle is engageable with a stopper surface of a guide unit to axially position the surgical needle. The guide unit has a guide passage extending substantially perpendicularly to the stopper surface, for guiding the end of the suture. An outlet of the guide passage opens to the stopper surface in confronting relation to a space between the staking dies. The guide passage has a tapered portion decreasing in cross-sectional area toward the outlet. The proximal end of the surgical needle is positioned by a positioning mechanism perpendicularly to the axis of the surgical needle so that the bore in the surgical needle is brought substantially into alignment with the outlet of the guide passage.

摘要： A method of forming a bore for attachment of an end of a suture, in a proximal end portion of an eyeless operating needle. An original needle is prepared which has its outer diameter greater than that of the operating needle. Beam is applied to an end face of a proximal end portion of the original needle to form the bore therein extending along an axis of the proximal end portion of the original needle, with an outer peripheral portion of the original needle serving as a heat conductive material. Subsequently, an outer diameter of the original needle is reduced to remove the outer peripheral portion from the original needle, to form the operating needle. Alternatively, a separate heat conductive material is disposed around at least one eyeless operating needle and is removed after the bore is formed in the proximal end portion of the operating needle.
