Surgical apparatus

The disclosure provides a surgical apparatus comprising: a steerable member that is bendable and comprises a plurality of bending segments with channels therein; and a plurality of bending actuation wires that are arranged to pass through the steerable member and cause the steerable member to bend, the steerable member comprising at least one outwardly opening lumen through which the bending actuation wires pass.

TISSUE THICKNESS COMPENSATOR COMPRISING A RESERVOIR

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

ARTICULATING MICROSURGICAL INSTRUMENT

An apparatus and method for an articulating microsurgical instrument is disclosed herein. The articulating microsurgical instrument may be configured to be operable with a Doppler probe, bone grasper, soft tissue grasper/dissector, scissors, flexible forceps, or a suction/irrigation line configured to provide tools within a surgical location that can be adjusted to a desired angle of operation. A tip assembly may comprise an articulating portion at a distal tip and the articulating portion may be configured to deflect upon actuation of an articulation control. The articulation control may be a trigger assembly or a roller wheel. A bayonet-style handle may include a set of posts configured to interact with the one or more control wires during actuation of the articulation control. One or more control wires may be housed in a lumen and actuated using a articulation control of a handle assembly.

11478306 · 2022-10-25 · ·

A medical manipulator system according to the present invention is provided with: a manipulator; a manipulator channel; a route that extends along the manipulator channel; a shape sensor that detects shape information of the manipulator channel; a shape-sensor driving portion that causes the shape sensor to be driven; a manipulator driving portion that causes the manipulator to be driven; a positional-information calculating portion that calculates positional information of the shape sensor on the basis of a driven amount of the shape-sensor driving portion; a shape estimating portion that estimates a bent shape of the manipulator on the basis of the shape information of the manipulator channel and the positional information; a control-parameter calculating portion that calculates a control parameter of the manipulator from the bent-shape information; and a manipulator controller that controls the manipulator on the basis of the control parameter.

STEERABLE CATHETER

A delivery system includes a handle, a catheter shaft, and a steering mechanism. The catheter shaft extends from the handle to a flexible distal end portion. The steering mechanism is configured to steer the flexible distal end portion. The steering mechanism can include a steering element a control member, and one or more actuation elements. Actuating the control member can move the steering element to increase and/or decrease tension in one or more actuation elements.

STIFFNESS-REINFORCED SURGICAL SYSTEM AND CONTROL METHOD THEREOF

Provided is a stiffness-reinforced surgical system. A stiffness-reinforced surgical system includes a plurality of links provided rotatably with each other to form a joint device, a main tendon configured to form a traction force for driving the links, an auxiliary tendon configured to form a traction force to resist rotation of the links, and a controller configured to control the traction forces of the main tendon and the auxiliary tendon. According to example embodiment, it is possible to provide a stiffness-reinforced surgical system configured such that an overtube forms sufficient flexibility while being inserted into the lumen and forms high stiffness during lesion removal, and a control method thereof.

ONE-HANDED AND DOUBLE ROW METHODS FOR TISSUE FIXATION

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation, namely embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein. Other preferred embodiments of the present invention relate to multi-anchor constructs that may employ threaded implants exclusively, push-in implants exclusively, or a combination of threaded and push-in implants.

Adhesive film laminate

A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion. The flowable attachment portion may be indefinitely flowable. The flowable attachment portion may be flowable from the time that layer is installed to the fastener cartridge to the time in which the layer is implanted to patient tissue. The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.

Posterior to lateral interbody fusion approach with associated instrumentation and implants
11602368 · 2023-03-14 ·

Methods for accessing a disc space of a patient as a part of an interbody fusion, as well as the tools employed therewith. An exemplary method may include inserting a leading end of a tool into the patient's back at a location on the posterior surface that is laterally offset from a patient's spinous process and disc. The tool's initial entry into the patient may be from a posterior approach. As the tool is advanced along its designated path, it begins to deviate from the posterior approach towards a lateral approach. When the leading end reaches the disc, it may access the disc from a lateral or substantially lateral location. The tool may be used to access the disc location, to remove disc material, to deliver a cutting tool for removing the disc material, and other steps associated with the spinal interbody fusion procedure.
