Embodiment Construction

[0065] Embodiments of the present disclosure will now be described in detail with reference to the drawings, wherein like reference numerals refer to the same or corresponding elements throughout the several views. As used herein, the term "clinician" refers to a doctor, nurse, or any other care provider and may include support personnel. Throughout this specification, the term "proximal" refers to the portion of the device or its components that is closest to the clinician, while the term "distal" refers to the portion of the device or its components that is furthest from the clinician.

[0066] The present disclosure relates to a loading unit for a powered or manual surgical handle that includes an end effector for engaging tissue. The end effector has jaws that rotate to a closed position and can take the form of a clamshell. The end effector includes a retainer jaw that is pivotally received in a groove defined by the fastener jaw. The retainer jaws are pivoted from the ...

Abstract

The present invention discloses a clamshell surgical stapling loading unit. A clamshell stapling end effector includes first and second jaws and defines an end effector axis. The first jaw has proximal, central, and distal portions. The central portion includes a first tissue contacting surface and defines a cavity. The second jaw includes a second tissue contacting surface and is rotatably secured to the first jaw about a rotation axis. The rotation axis is parallel to the end effector axis. The second jaw has a folded position such that the second jaw is positioned within the cavity of the first jaw with the first and second tissue contacting surfaces parallel to one another and facing in the same direction and a clamped position such that the first and second tissue contacting surfaces oppose one another. The present invention also discloses a loading unit.

Description

technical field [0001] The present disclosure relates to a surgical instrument, and more particularly, to an instrument for closing an open end of a hollow device. Background technique [0002] During a hysterectomy procedure, such as a laparoscopic total hysterectomy (TLH) procedure, the uterus and cervix are removed, resulting in a generally rounded structure at the end of the vaginal canal known as the vaginal cuff. Closure of the remaining vaginal stump becomes one of the most challenging aspects of the procedure. It is also seen as one of the obstacles to the use of laparoscopic surgery in open procedures to those skilled in the art. [0003] After the uterus is removed, it is necessary to close the vaginal stump while avoiding dehiscence if the wound ruptures along the surgical suture. Currently, vaginal stump closure is performed manually by means of needles and sutures or by means of suturing surgical instruments. Both methods require a lot of surgical skill and t...
