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： A triangular suture needle having a low thrust resistance and a press mold suitable for manufacturing the same are provided. The triangular suture needle includes: an angular triangular prism-shaped part (100a) on the needlepoint side; a rounded triangular prism-shaped part (100b) connecting to the needle base side of said triangular prism-shaped part; and a thread attaching part (100c) in a needle base end. The entire angular triangular prism-shaped part (100a) is ground, forming a pointed, sharpened part (100d) with a sharp tip. Furthermore, width (w1) of the thickest portion of the sharpened part (100d) is greater than width (w2) of the rounded triangular prism-shaped part connecting to that portion.

摘要： The present invention relates to a twisting apparatus for an ultrafine rectangular bar, comprising: a chuck; chuck driving means; at least two vise clamps each of the vise clamps having a pressing surface capable of contacting to a side surface of the ultrafine rectangular bar; and vise clamp driving means. The chuck driving means and the vise clamp driving means are so controlled that, after the proximal end of the ultrafine rectangular bar is held by the chuck where the vise clamps are placed closely to the ultrafine rectangular bar, the chuck disengages the ultrafine rectangular bar when the vise clamps contact to the ultrafine rectangular bar and then engages again the ultrafine rectangular bar, in a ease where the vise clamps are approached closely to the ultrafine rectangular bar held by the chuck to twist the ultrafine rectangular bar upon isolating, as rotated correlatively, the chuck and the vise clamps from each other.
