Hydraulically and electrically actuated articulation joints for surgical instruments

Articulation joints for use in connection with a surgical instrument that has a portion that must be passed through a trocar or similar structure and then articulated relative to another portion of the instrument received within the trocar. Various embodiments of the articulation joint include at least one fluid-actuated cylinder or flexible driven member to articulate the surgical implement relative to the handle assembly of the instrument.

End effector coupling arrangements for a surgical cutting and stapling instrument

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and / or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and / or disposable loading unit can further include a threaded collar and / or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

Stapling and cutting in resectioning for full thickness resection devices

InactiveUS7334718B2Suture equipmentsStapling toolsSuturing unitFull thickness excision
A stapling unit for use with an endoscopic stapling system adapted to be advanced along an endoscope to a predetermined location within a body lumen to staple the portion of tissue, as part of an occlusal or full thickness resectioning procedure. The stapling unit comprises a first casing having a distal end, a proximal end and a stapling device mounted thereto adjacent to a first window extending through a periphery of the first casing. The invention includes methods for the stapling, severing and removal of tissue by using the device.

Anastomosis instrument and method for performing same

A surgical instrument for anastomosis of first and second blood vessels includes a housing having distal and proximal ends and an actuator disposed therebetween. The actuator includes a handle and a link assembly, the link assembly being movable through a firing stroke in response to movement of the handle. The instrument also includes a disposable loading unit releasably attached to the distal end of the housing in mechanical cooperation with the actuator. The disposable loading unit supports a plurality of surgical fasteners, which deform upon movement of the actuator and the link assembly through the firing stroke.

Surgical stapling instrument

A surgical stapling instrument (1) comprises a staple fastening assembly (4) in the distal region of said instrument, the staple fastening assembly (4) including a cartridge device (8) which comprises at least one closed row (17, 18) of staples and defines a wavy distal end surface (14), and an anvil (9) which defines a wavy proximal staple forming surface (20) substantially matching the distal end surface (14) and which is adapted to cooperate with the cartridge device (8) for forming the ends of the staples exiting from the cartridge device (8), wherein the distal end surface (14) and the staple forming surface (20) have a globally wavy shape including two opposite peaks (21) and two opposite valleys (22) angularly spaced at about 90° from the adjacent peaks (21) and in that said two-peaks-two-valleys wavy shape is formed by a stepped configuration of said surfaces (14, 20).

Endoscopic tissue removal apparatus and method

An apparatus for withdrawing a tissue specimen being held by a grasping instrument through an endoscope includes an endoscope having an endoscopic shaft with proximal and distal ends and a lumen extending therebetween. The apparatus also includes first and second hoop-like support members which are selectively slideable within the lumen from a first position to at least one second position. Each of the hoop members includes a diameter which is variable from a first diameter to at least one different diameter. The apparatus also includes a pouch having first and second ends which attach to respective first and second hoop members. The pouch defines a container therein for retaining the tissue specimen. A pair of drawstrings are attached to the first and second ends of the pouch, respectively, and are remotely operable to close the ends about the tissue specimen.

Adhesive Mechanical Fastener for Lumen Creation Utilizing Tissue Necrosing Means

A two piece anastomosis device for attaching two organs together and creating a passage between the organs is disclosed. The anastomosis device has a first tissue clamping ring and a second tissue clamping ring that are brought together to clamp tissue therebetween and cut off the flow of blood to the tissue. The tissue clamping rings are locked together with an adhesive, and over time, causes the clamped tissue to necrose and slough off. The sloughed tissue creates a passageway through the anastomosis device. A method of using the fastener to create a bypass passageway between the stomach and small intestine is disclosed.

Piston-actuated endoscopic tool

Endoscopic apparatus is provided, having a distal end (102) for insertion into a body of a patient and a proximal end that is held outside the body of the patient. The apparatus includes a proximal cylinder (404), disposed in a vicinity of the proximal end of the endoscopic apparatus. A proximal piston (406) is slidably contained within the proximal cylinder. A distal cylinder (328) is disposed in a vicinity of the distal end of the endoscopic apparatus, and a distal piston (310) is slidably contained within the distal cylinder. A tube (402) for containing a liquid is coupled between the proximal and distal cylinders. A tool (e.g., biopsy tool 115) is coupled to be actuated by displacement of the distal piston, so as to perform a mechanical action on tissue of the body or contents of the body, responsive to displacement of the distal piston.

Endovascular fastener applicator

Endovascular fastener applicator for endoluminally fastening prosthetic grafts to vessels, are provided. The endovascular fastener applicator includes a delivery assembly configured for positioning within a vessel, and a control assembly mounted to a proximal end of the outer sheath for extracorporeal control of the delivery assembly. The delivery assembly includes an expandable portion disposed adjacent a distal end of an outer sheath and being expandable to support a prosthetic in contact with an inner surface of a vessel; a yoke assembly disposed within the expandable portion; an applicator head assembly pivotably mounted to the yoke assembly and movable between a loading position longitudinally aligned with the yoke assembly, and a firing position oriented substantially perpendicular to the yoke assembly; and a fastener assembly connectable to a distal end of the expandable portion, the fastener assembly retaining at least one fastener therein.
