摘要： A backflush needle allowing maintaining the shape of a soft member at the tip when passing through a cannula. A backflush needle is used in an ophthalmic operation with the backflush needle passed through a cannula attached to an eyeball. The needle includes a tubular needle main body to pass through the cannula, a tubular soft member connected to a front end of the needle main body, and a rod-shaped core member to pass through respective tubular hollow cavities of the needle main body and the soft member. The core member is axially movable, allowing protrusion of a front end of the core member from the soft member and retraction of the front end until a position detached from the needle main body.

摘要： Strength of a front end part having a sharp point of a medical suture needle is maintained and resistance when piercing tissue is reduced. There is provided a medical suture needle having a triangular cross section made of austenitic stainless steel having a fibrously extending structure, having two first slanted surfaces (11) ground and sandwiching a ridge (20), and a bottom surface (13) sandwiched between the two first slanted surfaces and ground. The ridge is formed comprising a first cutting blade (1) that is formed by the two first slanted surfaces (11) intersecting, a ridge part (20) that is formed on a body part side of the first cutting blade without the first slanted surfaces (11) intersecting, and a second cutting blade (2) that is formed by two second slanted surfaces (12) ground, intersecting and sandwiching the first cutting blade (1) on a front end side of the first cutting blade (1). Length L2 of the first cutting blade is within a range of 3 to 20 times length L1 of the second cutting blade (2), and a front end (3) of the second cutting blade (2) is positioned deviating from the material center.

摘要： [Problem] To provide a medical cutting tool with low impalement resistance. [Solution] The edged medical cutting tool comprising a knife, trocar or cutting suture needle has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge, and the color of the portion of the flat part (2a) along the edge (1) differs from the color of the rest of the flat part (2b). The difference in color results from a difference in the thickness of an oxide film. Another edged medical cutting tool is configured of austenite stainless steel and has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge. The chrome content of the portion of the flat part (2a) along the edge is higher than the chrome content of the rest of the flat part (2b).

摘要： There is provided a piercing needle-equipped cannula that has a pre-attached piercing needle, and no deformation of the slit portion due to the piercing needle is left after the piercing needle is pulled out. A piercing needle-equipped cannula (100) includes: a cannula (10) pierced in an eyeball and used in ophthalmic operations; a resin cap (13) having a slit (13a) opened in the cannula (10); and a piercing needle (15) attached to the cannula (10). The piercing needle (15) includes a needle main body (15c) on a front end side, a base (15d) on a base end side, and a slit piercing part (15s) piercing the slit (13a) in a state where the needle main body (15c) and the base (15d) are connected, and the cross-sectional area of the slit piercing part (15s) is smaller than that of the thickest part of the needle main body (15c).

摘要： A medical knife configured such that a cutting blade does not face upward when placed on a stand. A medical knife (10) includes a handle (20) and a cutting portion (30). The handle (20) includes a protrusion (20a) that makes point contact with a flat surface or makes line contact with the flat surface along the axis of the handle when trying to place the medical knife on the flat surface with a cutting blade (30a) of the cutting portion (30) of the medical knife facing upward. Moreover, the protrusion (20a) makes contact with a horizontal surface at a position deviating from a position defined by a line extending downward vertically from the center of gravity of the medical knife (10).

摘要： There is provided a packaging material for a suture thread with needle allowing extraction of the suture thread with needle from the packaging material without the suture thread being entangled, and making it difficult for the suture thread to be scraped at a point of the packaging material when extracting the suture thread with needle stored in the packaging material. The packaging material folded in three or more for storing the suture thread with needle includes a curved cutout part on an end part of the packaging material in an open state. A through-hole for the suture thread is formed by a crease and the curved cutout part when the packaging material is folded so that the curved cutout part is positioned on the inner side of the packaging material), and the suture thread passes through the through-hole when extracting the stored suture thread with needle from the packaging material.

摘要： A medical knife which maintains low penetration resistance, without the maximum-width parts of the medical knife creating sudden changes in penetration resistance even when passing through tissue. Knife includes a pointed tip, a cutting part which has edges having first oblique faces which are formed along the outer periphery, and second oblique faces which are formed inside the first oblique faces. Maximum-width parts are formed contiguously with the cutting part. A shank part is formed contiguously with the maximum-width parts. The cutting part is formed in such a way that the shape of the planar projection thereof becomes wider from the pointed tip towards the maximum-width parts, and the first oblique faces extend further towards the shank part side than the second oblique faces over at least one portion of the area running from the maximum-width parts to the shank part.

摘要： There is provided a suture needle having a base end surface to which either both ends of a single suture thread or two suture threads are attached allowing easy and secure attachment even of a thicker suture thread than in the past. A suture needle, which is provided with a blind hole along the axis from a base end surface of the suture needle, and a suture thread attached by inserting the suture thread in the blind hole and crimping it, is characterized by having the blind hole opened in two places in the same base end surface, and thereby both ends of a single suture thread or two suture threads may be attached to the needle. Moreover, the blind holes opened in two places may be connected so as to make overall shape of the blind holes in the base end surface have a figure eight shape.
摘要翻译：提供了一种具有基端面的缝合针，单个缝合线或两根缝合线的两端都可以连接到基端面，即使是比以前更粗的缝合线也容易且牢固地附着。缝合针从缝合针的基端表面沿轴线设置有盲孔，并且通过将缝合线插入盲孔中并将其压接而附接的缝合线，其特征在于，盲孔打开在同一基端表面的两个位置，从而可以将单个缝合线或两个缝合线的两端附接到针上。此外，可以将在两个位置打开的盲孔连接成使得基端面中的盲孔的整体形状具有八字形状。

摘要： This invention relates to a dental reamer used in dental treatment for forming a root canal, in which the dental reamer prevents digging into a root canal wall and deviation even when attached to a handpiece and driven by an engine. With this reamer, a spiral working portion is formed by grinding and cutting away a tapered rod with two oppositely faced lines, and then, the ground material left with two arcs and a center of a circle is inserted into a molding space comprised of a pair of holding jigs and support jigs to perform the twist-process. In association with the twist-process, a cutting portion and a flank portion are formed on both ends of the working portion.
