A C-type tubing cutter is described that accommodates and cuts a range of tubing or workpiece sizes. The cutter includes a radially positionable roller carriage that can be selectively positioned in one of several predetermined positions corresponding to different tubing sizes. The cutter also includes a trigger that can be engaged with the roller carriage to lock the carriage in a desired position. Certain versions of the cutters also utilize arcuate slots or tracks along which a cutter wheel is positionable.

C-type tubing cutters are described. The cutters include a cutting wheel that can be easily and quickly replaced. In many versions of the cutters, the cutting wheel can be replaced without disassembly of the housing and/or without the use of tools.

A pipe cutter for cutting a pipe includes a cutting head assembly having a first carriage and a second carriage spaced apart to define a cutting area. The first carriage supports a cutting mechanism, and the second carriage is configured to support a pipe within the cutting area. The carriages have a locked state and an unlocked state such that when the carriages are in the unlocked state, the carriages are movable relative to each other and biased into the cutting area. The pipe cutter also includes a drive assembly configured to rotate the cutting head assembly and a locking mechanism configured for changing the carriages from the unlocked state to the locked state and for holding the carriages in the locked state. The locking mechanism includes an actuation member rotatably coupled to the first carriage.

A pipe shears includes a base, a ratchet plate pivotally connected to the base, a cutter blade detachably mounted to the ratchet plate, a positioning member mounted between an elongated hole of the ratchet plate and a positioning groove of the cutter blade, and a push rod inserted in the base and stopped against a stop member. When the push rod is not pushed, it is positioned in the elongated hole of the ratchet plate and stopped against the positioning member to force the positioning member into engagement with the positioning groove of the cutter blade, and the cutter blade is not detachable at this time. When the push rod is pushed, the stop member is moved out of the elongated hole of the ratchet plate to unlock the positioning member from the positioning groove of the cutter blade for allowing removal of the cutter blade.

The invention relates to manual pliers (1) which comprise a fixed cutting jaw (26) and a movable cutting jaw (23). The manual pliers (1) comprise a first maximal opening position in which it is possible to run through a working stroke part caused by the closure of the hand levers (2). In the first maximal opening position the latching lever (16) and a pushing lever (19) engage with a toothing (32) of the movable cutting jaw (23). With the actuation of the latching lever (16) it is possible to transfer the manual pliers into a second maximal opening position in which the opening angle of the hand levers (2) is larger than in the first maximal opening position. In the second maximal opening position the latching lever (16) and the pushing lever (19) do not engage with the toothing (32) of the movable cutting jaw (23). For the definition of the two opening positions, two stops are used which are formed by the latching lever (16) and a swivel bolt of the latching lever (16).

A multifunctional tool includes first and second handle members, first and second jaw members operatively connected to the first and second handle members and movable between a first open position and a second closed position, and first and second removable collar attachment members configured to be removably installed in the first and second jaw members, respectively, to provide different sizes of compressing and/or cutting diameters when the first and second jaw members are in the second closed position.

The present invention discloses a tube cutter which includes a first clamp handle, a second clamp handle, a blade, and a holder. The first clamp handle includes an opening. The second clamp handle is pivotally connected with the first clamp handle. The blade is connected with the second clamp handle. The holder comprises a first recess and at least one second recess, wherein the first recess has a width wider than that of the at least one second recess. The holder is movably connected with the first clamp handle to form a first state or a second state with respect to the first clamp handle, wherein the first recess is located at the opening when in the first state and the second recess is located at the opening when in the second state.

A cutting device with wheeled blades has a shear and a cutting wheel set-blade. The shear has a first handle and a second handle pivoted together via a pivot member, the first handle extending to form a first arm, and the first arm provided with a connecting aperture, and the second handle extending to form a second arm, an assembling aperture provided at an end of the second arm. The cutting wheel set-blade having two positioning wheeled-blades, a third arm and a movable wheeled blade. The positioning wheeled-blades are respectively connected to the connecting aperture and the assembling aperture of the shear, the third arm lockable with the adjustment apertures of the shear via a knob, a locking aperture provided on the extended third arm and engaging the movable wheel-blade, and the two positioning wheeled-blades and the movable wheeled blade are disposed in a triangular arrangement on the shear.

Access port cutters and related systems and methods can be used to cut an access port to a desired length based on particular patient and/or surgical procedure needs at a point of use. More particularly, an access port cutter can include a base with an opening that can receive an access port therein such that a desired length of the access port can extend from the opening. An actuation mechanism can translate a blade linearly along at least a portion of the base such that the blade can traverse the opening and cut across the access port. In some embodiments, the actuation mechanism can include a handle that can pivot relative to the base to drive the blade. One or more safety features can reduce the risk of inadvertent actuation of the blade and/or prevent debris from contaminating a surgical site or falling onto a patient.
