A barbed microcatheter includes a hollow tube having an elongated lumen, outwardly projecting barbs, fluid egress openings, a tissue anchor secured to a proximal end of the hollow tube, and a needle secured to the distal end of the hollow tube. The needle is used to form a first tissue opening at the first end of the wound. The hollow tube is pulled through the first tissue opening until the tissue anchor abuts against tissue at the first end of the wound. The needle is used to form a second tissue opening at the second end of the wound. The hollow tube is pulled through the second tissue opening so that barbs engage wound tissue. After cutting away the needle, a therapeutic fluid is introduced into the elongated lumen and passes through the fluid egress openings for infusing the wound with the therapeutic fluid.

The present invention relates to a rechargeable hydraulic punching machine for a cable tray, in which a battery, a grip, a motor, a hydraulic cylinder, a punch, and a die are sequentially disposed along a straight line, a C-shaped head coupled to the head of the hydraulic cylinder is disposed, the punch and the die are disposed at both open ends of the C-shaped head, respectively, punch guards are disposed on a portion of the head spaced apart from both sides of the punch, the battery is configured to be charged and detachably attached, the motor transfers power to the hydraulic cylinder by using the power of the battery, and the hydraulic cylinder punches assembly holes of a cable tray by pushing the punch in the direction of the die by using hydraulic power based on the power of the motor.

A hand-held apparatus is for hole-making in an elongated body. The apparatus has a housing including a rotatable cutting tool arranged to be axially movable from a non-cutting position into a cutting position. The first end portion of the housing comprises a clamping device arranged to be adjusted from a first, inactive position into a second, active position, wherein the clamping device, in the active position, is arranged to hold the apparatus fixed to the elongated body. The apparatus further has a device for connecting to a driving means, for example a hand-held drill.

A handheld punch tool includes a housing, a die holder coupled to the housing, a die supported by the die holder, the die and the die holder defining a feed slot therebetween for receiving a workpiece to be cut, and a punch configured to reciprocate within the die holder, with a main body defining a first longitudinal axis extending centrally through the main body and a punch element extending from the main body along a second longitudinal axis parallel to the first longitudinal axis. The punch element is configured to cut a first distance into the workpiece per stroke of the punch when the feed slot faces a first side of the punch and to cut a second distance into the workpiece per stroke when the feed slot faces a second side of the punch opposite the first side. The first distance is greater than the second distance.
