Abstract: According to the aspect of the present disclosure, various forms of medical 3D threads produced using ultrasonic waves are provided. Thus, we can expect high satisfaction with the medical 3D threads having high tensile strength and holding power. The medical 3D threads can be produced to have about twice as many barbs as conventional medical threads and can be produced using ultrasonic waves without damaging yarn or making knots. Thus, it is possible to overcome the cause of a decrease in physical strength.

Abstract: A system for making braided barbed sutures includes a filament winding assembly, a barbed insert including an elongated core and barbs extending outwardly from the elongated core, and a barbed insert dispenser opening defining a passageway for orienting the barbed insert as the barbed insert is dispensed into the filament winding assembly. The barbed insert dispenser opening allows longitudinal movement of the barbed insert relative to the barbed insert dispenser opening while simultaneously preventing twisting movement of the barbed insert relative to the barbed insert dispenser opening.

Abstract: A cutting apparatus includes a wire cutting member, a plurality of wheels about which the wire cutting member is at least partially wrapped, a first arm member supporting at least one of the plurality of wheels, and a second arm member supporting at least one of the plurality of wheels. The first arm member and the second arm member may be moveable between a first position, in which the cutting apparatus has a first size, and a second position, in which the cutting apparatus has a second size larger than the first size. A wire saw includes an adjustment member coupled to at least one of a plurality of wheels for moving the at least one of the plurality of wheels to adjust a tension of a wire cutting member.

Abstract: The present invention relates to a saw blade for a sawing machine, said sawing machine (10) being arranged for cutting micro trenches by means of said saw blade (1), wherein said micro trenches are adapted for receiving at least one duct/cable; wherein said saw blade comprises mechanical coding means (2) selected from the group consisting of holes, depressions and protrusions arranged on said saw blade (1); and said holes, depressions and protrusions being coding elements for forming at least one code symbol (4) representing a unique identity (ID) for said saw blade.

Abstract: A cutting structure for plastic film includes a bracket, a first roller, a second roller, a tachometer, a processor, a monitor and a cutter. The bracket includes a bottom and two sidewalls extending from the bottom along a same direction. The first roller includes a shaft fixed to the sidewalls and a sleeve rotatably sleeving on the shaft. The second roller is pivotally connected to the sidewalls. The tachometer is disposed on one end of the second roller and configured for measuring the rotation speed of the second roller. The processor is configured for reading the rotation speed and further calculating a rotation distance of the second roller. The monitor is configured for displaying the rotation distance. The cutter extends upward from the bottom for cutting the plastic film pulled from the first roller and the second roller.

Abstract: The invention relates to a collision sensing device which can detect a collision between two or more objects. The collision sensing device comprises a deformable member (5) that defines a space (15) which can be assigned a pressure. In a first condition, the deformable member is undeformed, whereby the space (15) is assigned a first pressure (P1). In a second condition, the deformable member (5) is deformed whereby the space (15) is assigned a second pressure (P2). The pressure in the space is monitored. A collision with an object is detected when the pressure in the space changes from the first pressure to the second pressure. The invention can e.g. be applied in connection with machining, such as water jet cutting, but several other fields of application are also conceivable.

Abstract: A handheld power tool having a power tool that executes a reciprocating motion, in particular a reciprocating power saw with a reciprocating sawblade (14), is disclosed. To prevent the power tool from sawing untrue during the cutting operation, in particular between the upper and lower cutting edges, the power tool is assigned at least one force transducer (19), which measures the magnitude of a transverse force, oriented transversely to the direction of motion, that occurs at the power tool, and at least one actuator (21), which acts on the power tool as a function of the measured magnitude of the transverse force, is provided for transverse force compensation.

Abstract: A barbed suture for connecting tissue, and a combination surgical needle with a barbed suture. The suture includes an elongated body and a plurality of barbs projecting from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. The disposition of the barbs on the body may be staggered, twist cut multiple spiral, overlapping, or random. Also, the configuration of the barbs may be a certain spirality angle &agr;, barb cut angle &THgr;, barb cut depth, barb cut length, barb cut distance, corrugated barb underside, arcuate barb base, or varying barb size.
