Instrument for occlusion of uterine blood vessels

A surgical instrument for at least partial occlusion of the uterus blood vessels comprising two opposing jaws with scissor-type handles and a latching mechanism. Each jaw has a straight member 1 and a straight member 2 connected with an angle 30-45 degrees. Each said member 1 has a tubular cover. Each member 2 is integrated with the scissor-type handle. Each jaw has an inner side and an outer side. The jaws are made movable relative to each other in order to at least partially occlude the uterus blood vessels by the opposite sides of the covers on the inner sides of the members 1. The latching mechanism is made to retain the jaws in the working position over a needed period of time and release the jaws when the need for occlusion is over. Each cover has an inner cavity open from one end for receiving and retaining the member 1 of said jaw. The thickness of each said cover on the inner side of the member 1 is 8-12 mm, the width of said cover is 10-30 mm, the length of said cover is 50-60 mm, and said cover is made of soft plastic, silicon, fabric, gauze or non woven material.

Ultrasonic surgical instrument with staged clamping

An apparatus comprises a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm comprises a clamp pad. The clamp arm is movable toward the ultrasonic blade to compress tissue between the clamp pad and the ultrasonic blade in two stages. During the first stage, the clamp arm is configured to compress tissue with only a distal portion of the clamp pad. During the second stage, the clamp arm is configured to compress tissue with the distal portion and a proximal portion of the clamp pad. Thus, the tissue compression begins at the distal portion and subsequently progresses toward the proximal portion.

Sleeve features for ultrasonic blade of a surgical instrument

An apparatus comprises a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade, a clamp arm, and a sleeve. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is configured to move toward the ultrasonic blade. The sleeve extends along at least part of the length of an outer portion of the ultrasonic blade or the clamp arm. The sleeve is configured to prevent tissue from contacting a portion of the ultrasonic blade or clamp arm covered by the sleeve.

Shielding features for ultrasonic blade of a surgical instrument

An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

Electrically conductive/insulative over-shoe for tissue fusion
09980770 · 2018-05-29 · ·

An over shoe for use with electrosurgical instruments having a pair of juxtaposed jaw members pivotably associated with one another, at least one of which includes an electrically conductive surface disposed thereon which is in electrical engagement with an electrosurgical energy source. According to one aspect of the present disclosure, the over shoe includes a tissue contacting wall configured and dimensioned to selectively and substantially overlie the electrically conductive surface of the electrosurgical instrument. The tissue contacting wall is fabricated from a non-conductive material and includes a plurality of apertures formed therethrough. In another embodiment, the tissue contacting wall is electrically conductive and is configured for selective engagement atop on of the jaw members.

A jaw member for use with a surgical instrument includes a support base, a jaw liner, and an elongated plate. The support base defines a cavity therein configured for receipt of the jaw liner. The elongated plate is configured to be seated in the cavity of the support base adjacent the jaw liner to secure the jaw liner relative to the support base.

APPARATUS, SYSTEMS, AND METHODS OF FACILITATING MANIPULATION OF TISSUE
20180132896 · 2018-05-17 ·

A method includes advancing a surgical device into a vaginal opening of a subject such that the surgical device remains proximal of a cervix of the subject, transitioning the surgical device from a first state to a second state such that an outer surface of the surgical device applies force to vaginal walls of the subject in a radially outward direction to frictionally engage the vaginal walls, and moving the surgical device in a caudal direction to manipulate the cervix. Surgical devices systems include a surgical device that is transitionable between the first and second states to frictionally engage the vaginal walls. The surgical device systems further include a friction-enhancing material disposed on at least a portion of the outer surface of the surgical device. The friction-enhancing material is configured to increase frictional engagement of the at least a portion of the surgical device with the vaginal walls.

Double Forceps
20180078271 · 2018-03-22 ·

Handheld forceps having plural pincers for grasping and holding multiple objects, such as Peanut or Cotton Kittner sponges, at the same time are disclosed. The handheld forceps include opposing arms having proximal and distal ends. A hinge connects the opposing arms together between the proximal and distal ends. The opposing arms articulate relative to each other about the hinge. A handle portion at the proximal ends of the opposing arms has an open and closed position for articulating the distal ends open and closed. Distal ends are configured with plural pincers whereby jaws are formed between the plural pincers for grasping and holding multiple objects at the same time.

Manipulator for grasping tissue

A manipulator adapted to grasp and draw tissue comprises first and second arms having proximal ends and distal ends separated by a distance. First and second grasping surfaces each connected to and extending from respective distal ends of the first and second arms are biased toward each other by a respective spring force. When the first and second arms are actuated to reduce the distance, the manipulator is configured such that tissue arranged between the first and second grasping surfaces resist actuation of the first and second arms. The first and second arms are further actuatable to overcome the spring force of the first and second grasping surfaces so that the first and second grasping surfaces pivot at respective pivot points such that the distance between the distal ends of the first and second arms is reduced.
