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

Systems, devices and methods are provided for endoscopic procedures involving tissue manipulations beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body having a scope therethrough and at least one steerable tool arm which extends from the distal end of the main body. In preferred embodiments, the system includes two tool arms, each arm steerable to form a curve laterally outward which then bends laterally inward so that the arms form an angular shape. In addition, end effectors extend from the distal ends of each tool arm for use in manipulation of tissue. The angular shape brings the end effectors together in view of the scope for cooperative movements which are continuously visible by the surgeon. In addition, the tool arms may be steerable in any additional direction and may be rotateable to allow grasping, elevation and more complex manipulation of tissue.

Endoluminal tool deployment system

PROBLEM TO BE SOLVED: To easily carry out the remote control of a treatment tool from the direction suitable for the treatment with regard to the morbid portion, without interfering the field of vision of an endoscope. SOLUTION: This endoscopic therapeutic 1 is made up of an endoscope 2, two forceps 3 as a treatment tool, two treatment-tool guiding/inserting tool 4 in which the two forceps 3 are inserted and first and second bent parts 28a, 28b bent in the opposite directions to each other are provided respectively one by one, a therapeutic device guiding tube body 5 for arranging and holding the two inserting tools 4 in the symmetrical positions to each other with regard to the endoscope 2, and the like. The device 1 is inserted into the body cavity of a patient, and while observing the morbid portion with the endoscope 2, the first and second bent parts 28a, 28b are bent by remote operation, and the morbid portion is grasped with the two forceps 3 in the symmetrical position on the both sides of the endoscope 2 apart from the remote end surface of the endoscope 2. Thus, the morbid portion can be cut off with an electric surgical knife 16 incorporated in the endoscope 2. COPYRIGHT: (C)2000,JPO

Endoscopic therapeutic device

PROBLEM TO BE SOLVED: To provide an endoscopic treatment apparatus which can reduce limitation in treatment when a plurality of treatment instrument is introduced by a plurality of elasticity introducing guide tubes. SOLUTION: The endoscopic treatment apparatus has a plurality of introducing guide tubes 4a, 4b having curved parts 11, 12 capable of conducting curving operation. A plurality of introducing guide tubes 4a, 4b are connected and fixed. Their fixing part is used as a fulcrum 27 to move the curved parts 11, 12 of the introducing guide tubes 4a, 4b.

Capsule type medical treatment device

PROBLEM TO BE SOLVED: To easily treat the tissue part of an affected part or the like over a wide range by using an endoscope provided with at least two channels for passing through a treatment tool. SOLUTION: This endoscope 1 is provided with at least two channels 21 and 22 for passing through the treatment tool. In this case, the tip opening parts 23 and 24 of at least one or more of the plural channels 21 and 22 are provided with forceps electing table 27 for controlling the projecting direction of a treatment tool projecting therefrom, and the table 7 is fixed so as to erect the treatment tool in the direction of being away from the parts 23 and 24 of the other channel 21 and 22.

Endoscope for treatment

PROBLEM TO BE SOLVED: To provide an endoscope insertion aid securing a high insertion property even if an insertion rout is long or complicatedly curved. SOLUTION: This endoscope insertion aid is provided with an inside overtube 1B for inserting the endoscope in the inside and capable of assuming a flexible and passively shape-variable first state and a second state of being fixed its shape by a frictional force; and an outside over tube 1A for inserting the inside overtube 1B in the inside and capable of assuming the first state and the second state. This aid is inserted in the body cavity by repeating the following actions that the outside over tube 1A is fixed, the inside over tube 1B is advanced in the body cavity with the help of the curved part of the endoscope, then the over tube 1B is fixed, and the over tube 1 is followedly advanced therein.
