A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween. The surgical clip applier can include a variety of features to facilitate use of the device, including features to prevent misalignment of the jaws and clip therebetween, features to protect the jaws, and features to ensure proper closure of the jaws and clip therebetween.

Surgical clip applier

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Method of suturing a trocar path incision

A trocar assembly includes a cannula assembly, an obturator assembly, and a catch arm. The cannula assembly has a housing, a cannula, and a working channel defining a longitudinal axis from a proximal opening to a distal opening. The obturator assembly includes a proximal head, a distal tip, and a shaft extending therebetween. The catch arm is selectively moveable from a retracted position to a first and second deployed positions and is configured to releasably capture a suture thread. In the retracted position, the catch arm is positioned radially inward from the first deployed position. In the first deployed position, the catch arm is positioned radially outward from the retracted position. In addition, the catch arm is configured to be moved a predetermined distance from the first deployed position to the second deployed position and release the captured suture thread therefrom.

Needle guide instrument with transverse suture capture feature

A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.

Surgical clip applier methods

Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.

Hydraulic fracturing system and method

An apparatus is operable to secure suture fasteners to sutures to eliminate the need to tie knots in the sutures. The apparatus comprises a shaft, an end effector disposed at the distal end of the shaft, and a suture fastener removably secured to the end effector. The end effector may include a pivoting jaw or a suture cutter. The suture fastener may be secured to one, two, or more strands of suture. The apparatus may include several suture fasteners and may secure those fasteners to one or more sutures in a serial fashion without having to remove the apparatus from the patient for reloading. A plurality of fasteners may be arranged within the apparatus in an end-to-end configuration. The suture fastener may include an inner fastener member and an outer fastener member, and may capture one or more strands of suture between the inner and outer fastener members.

Suture fastening device

A tissue retrieval device comprises a tissue retrieval bag and resilient arms. The bag is releasably engaged with the resilient arms. One or two resilient arms expand the bag along a first plane to open the mouth of the bag. Another resilient arm expands the bag along a second plane to unfurl the bag. The first plane is substantially perpendicular to the second plane. The device further comprises a support tube having a passageway and a push/pull rod slidingly positioned within the passageway. The resilient arms are engaged with the push/pull rod such that the resilient arms and the push/pull rod travel uniformly relative to the longitudinal axis of the support tube. The arms collapse within the support tube and are resiliently biased to extend outwardly when the push/pull rod is translated distally relative to the support tube to expose the bag and arms.

Tissue retrieval device with pouch stretching arm

A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is insertable into a patient through a trocar. The bag may be selectively exposed at the distal end of the introducer tube, receive a tissue specimen, and be withdrawn from the patient. The bag includes a plurality of folds allowing the bag to transition from a folded configuration to an unfolded configuration. The folds may extend along a length of the bag transverse to the introducer tube; or along a length of the bag parallel to the introducer tube. The folds may extend about a perimeter of the bag, such as a circumference of the bag, and may be spaced apart along a length of the bag transverse to the introducer tube. The folds may be formed by petals that provide the bag with a generally spherical configuration when the bag is unfolded.

Tissue retrieval device with gusseted pouch

A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The tissue retrieval bag may be selectively exposed at the distal end of the introducer tube within the patient. The tissue retrieval bag may receive a tissue specimen and be withdrawn from the patient. The tissue retrieval bag may include an inflatable portion. When inflated, the inflatable portion may extend the tissue retrieval bag from a contracted configuration to an expanded configuration. The inflatable portion may substantially seal a tissue specimen within the tissue retrieval bag. The tissue retrieval bag may me formed of an environmentally sensitive material such that the size of the tissue retrieval bag expands when the tissue retrieval bag is exposed within the patient.

Tissue retrieval device with bladders

Surgical clip advancement mechanism

A surgical access port comprises a wound protector adapted for insertion into a wound in the abdominal wall of a patient. A resilient pad comprising a laminated structure with a plurality of layers of resilient materials is attached to the wound protector. The pad comprises an aperture adapted to receive and seal against a surgeon's arm or surgical instruments and is self-closing in the absence of a surgeon's arm or surgical instrument.
