A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical Stapling Apparatus

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

PROBLEM TO BE SOLVED: To improve safety and operability by providing a dissection section which is not insulated, in a range of a specified mm from the tip end of the exposed section of a knife wire which is exposed at the tip end of an insertion section, and insulating the remaining section. SOLUTION: On an exposed section of a total length Y of a knife wire 6 which is exposed at the tip end section of an insertion section 3, a range X of 5-15 mm from the tip end is formed into a dissection section 9 which is not insulated. An insulated section 10 is provided by applying an insulation on the section excepting the dissection section 9. The insulated section 10 is formed by coating 11 a fluorine based resin, or the like, for insulation, on the outer peripheral surface of a wire strand of the knife wire 6. By applying a high-frequency to the dissection section 9, the biological tissue of a lesion is incised. Also, the dissection section 9 and the coating 11 of the insulated section 10 are made to have different colors, and they may be made identifiable. By this constitution, safety and the operability can be improved.

Treating utensil for endoscope

PROBLEM TO BE SOLVED: To provide a guide wire insertion aid which can achieve the prevention of buckling of the guide wire, shortening of the time for insertion and removal work, the curtailment of the man-hours of provided with a helper, etc., in the insertion and removal work of the guide wire, can improve the insertability of the guide wire to a guide wire insertion appliance, enables the helper to easily carry out the work to rotate the guide wire, facilitates the operation of the guide wire and can make the craft of the guide wire easier. SOLUTION: This guide wire insertion aid is provided with a guide wire insertion aid body 17 which intermittently performs the action to insert and remove the guide wire 2 into and from a catheter 1 by repeating the action to move the guide wire 2 locked to a locking section 18a of an inner cylindrical member 16 together with the inner cylindrical section 16 by accompanying the action to project and sink the inner cylindrical member 16 into and out of an outer cylindrical member 15 and the inner cylindrical member 16 is provided with a rotation regulating section 25 of the guide wire 2.
