Described herein are various method of using a direct drive system to perform procedures at a distance. One exemplary method include tying a knot or suturing at a distance with a first and second end effector. The direct drive system can enable sufficient end effector dexterity, including the ability to control various degrees of freedom of end effector movement, and allow a user to perform complicated task at a distance. In one aspect the direct drive system includes flexible tools that permit access to surgical site via a natural orifice.

ADVANCED MINIMALLY INVASIVE MULTI-FUNCTIONAL ROBOTIC SURGICAL DEVICES AND METHODS
20220117617 · 2022-04-21 ·

Minimally invasive, multi-functional robotic surgical tool devices for use as lavaging, material aspiration or delivery surgical forceps, scissors or clamp or other device, consisting of a monolithic work element and open central lumen with various functional tips. Such devices may in use follow a central lumen of another device or over a wire in a longitudinal direction upon introduction to a body. Flush and vacuum transport mechanisms, imaging mechanisms or energy source mechanisms may be incorporated. Inner and outer sheaths which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks and provisions for simultaneous beak closing under rotation may be incorporated.

Cutting mechanisms for surgical end effector assemblies, instruments, and systems

An end effector assembly configured for use with a surgical instrument or surgical system includes first and second jaw members each including an outer jaw housing, a tissue-treating plate, and a longitudinally-extending channel therethrough. At least one of the first or second jaw members is pivotable relative to the other between a spaced-apart position and an approximated position. A cutting mechanism is configured to cut tissue grasped between the jaw members. The cutting mechanism may include an activation member coupled to a knife and configured to advance the knife transversely between the jaw members, a heat-activated elongated sheet configured to un-roll to advance a cutting edge thereof transversely between the jaw members, or a clutch and spring mechanism configured to deploy a knife longitudinally between the jaw members.

TOOL FOR NEUROMA TREATMENT AND NERVE REGENERATION PROCEDURES

The present disclosure provides a mechanically-actuated tool for cutting a tissue graft having a hollow core and methods for use thereof. A portion of a biological structure, such as a nerve, is attached to the hollow core to form an implantable neural graft assembly. The tool has a cutter mechanism and a grasper mechanism. The grasper mechanism has one or more component(s) that open and close via an actuation mechanism, like a handle, and rotate via a controller component, like a rotatable wheel. The cutter mechanism may be a cutting tube component that harvests the tissue graft. The tool may also have an ejector mechanism to remove the tissue graft as part of the implantable neural graft assembly. Such devices and methods are particularly suitable for treating neuromas and other neural regeneration procedures.

METHOD AND DEVICE FOR THE PERCUTANEOUS RELEASE OF THE A1 PULLEY IN THE HAND
20220022909 · 2022-01-27 ·

A method and device for the percutaneous release of the A1 pulley in the hand, as the triggering of the associated tendon can occur at the A1 pulley in the hand. A blade/hook construct is provided to release the A1 pulley and subsequently confirm the release. The blade and hook are disposed about opposite ends of an elongated shaft, allowing the tool to be used for both cutting and confirming the release of the A1 pulley in the hand. The blade assembly is adapted to avoid damage to adjacent structures, such as nerves and arteries. Advantageously, the A1 pulley may be cut in a distal-to-proximal or proximal-to-distal manner and the percutaneous skin incision may be made centered over the mid-portion of the A1 pulley, or it may be made more proximal or distal.

SURGICAL MULTI-TOOL AND METHOD OF USE
20210361346 · 2021-11-25 ·

Surgical tools are disclosed that include a first handle having a first recess, a second handle having a second recess, a first tip disposed in the first recess and extending distally, and a second tip disposed in the second recess and extending distally. The first tip has a first external surface and a first internal surface. The second tip has a second external surface and a second internal surface. The surgical tool has a first configuration wherein the surgical tool operates as forceps. The surgical tool has a second configuration wherein the surgical tool operates as scissors. The first internal surface can be moved adjacent to the second internal surface to permit rotation of the first tip relative to the first recess and permit rotation of the second tip relative to the second recess. The rotation of the first tip and the second tip transitions the surgical tool between the first configuration and the second configuration.
