A system, and method of using the system, for changing the angle of a bone of a subject is provided by the present disclosure. In one embodiment the system includes a non-invasively adjustable implant configured to be placed inside a longitudinal cavity within the bone and comprising an outer housing and an inner shaft telescopically disposed in the outer housing, at least one of the outer housing and inner shaft associated with a first anchor hole and a second anchor hole, the first anchor hole configured to pass a first anchor for coupling the adjustable implant to a first portion of bone and the second anchor hole configured for to pass a second anchor for coupling the adjustable implant to the first portion of bone, the inner shaft configured to couple to a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes the inner shaft to extend from the outer housing and to move the first portion of bone and the second portion of bone apart angularly; a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; and wherein the first anchor hole is configured to allow the first anchor to pivot in at least a first angular direction and the second anchor hole is configured to allow the second anchor to translate in at least a first translation direction.

An adjustable bowel treatment arm (110) features a telescoping shaft (112) having a proximal end and a distal end. A handle (118) is secured to the distal end of the telescoping shaft, while a pivot junction (122) positioned at the proximal end of the telescoping shaft. A stem has a proximal end and a distal end, where the distal end of the stem is attached to the pivot junction. A head (124) is attached to the proximal end of the stem.

In one embodiment, a surgical rigid arm (100, 150, 200, 900) includes a first portion (102, 152, 202, 902), a second portion (103, 153, 203, 903) and a central portion (105, 154, 205, 906), where the central portion is extends between the first and second portions. A first end of the first portion and a second end of the second portion are each attached to a peripheral side (14) of a surgical bed (10, 30) such that the first portion and the second portion extend from the surgical bed in a first direction. The central portion extends substantially horizontally and is positioned over the surgical bed, the central portion being connected to the surgical instrument such that a load from the surgical instrument is distributed across the central portion to the first portion and second portion to provide rigid support for the surgical instrument.

An aspiration catheter is provided including a proximal section and a distal section extendable through the proximal section. A vacuum transfer tool may be coupled to a proximal end of the proximal section. The vacuum transfer tool may include a proximal transfer tube and a distal transfer tube, each having an aspiration port in communication with a vacuum source. The proximal transfer tube may be removably received within a proximal end of the distal transfer tube. The proximal transfer tube may maintain a vacuum around the proximal end of the distal section of the catheter such that when the distal section is removed by decoupling the proximal and distal transfer tubes, the vacuum within the distal transfer tube and proximal section of the catheter is maintained, preventing the escape of any clots.

A telescoping access cannula comprising: an outer tube; an inner tube carried by the outer tube, the inner tube being coaxial with the outer tube and longitudinally movable relative to the outer tube; and a rotatable member carried by the outer tube and connected to the inner tube, wherein rotation of the rotatable member causes longitudinal movement of the inner tube relative to the outer tube.

A tissue retractor comprising an outer ring, an inner ring, and a flexible, metal sheath extending therebetween is described. Embodiments of the inner ring comprise a flat or wedge-shaped conformation useful for insertion between muscle layers. Other embodiments of the inner ring include variable diameter inner rings, where the diameter can be adjusted as required and optionally locked into place, and reshapeable inner rings that permit a user to conform the inner ring to the anatomy of the patient when placing the inner ring.

A surgical device may include a disposable needle assembly, a reusable handle assembly, and a retractable slide. The handle assembly may include a ratchet mechanism, a locking mechanism, an arming mechanism, and a cage. A method for inserting and releasing the disposable needle assembly from the reusable handle assembly is also disclosed herein.

The present disclosure describes a spinal fixation system comprising a telescoping spinal rod, as well as methods of its use and a guide tower for use therewith. The telescoping rod can be extended after it has been inserted into the patient below the fascia, which permits it to be extended in the sub-fascial space.

A flow blocking catheter including an inner tube, an outer tube and a flow blocking member is provided. The flow blocking member has one end attached to an outer circumference of the inner tube and the other end attached to a distal end of the outer tube. The flow blocking member is configured to expand as the outer tube moves toward a distal end of the inner tube and to collapse as the outer tube moves away from the distal end of the inner tube. In this way, expansion of the flow blocking member is able to be controlled simply by pushing/retracting the outer or inner tube to offer a fast shifting between different configurations. The flow blocking member is able to occlude blood flow with a controllably expansion to lower stimulation to the wall of the blood vessel and avoid the easy bursting of the balloon.

A robotic surgery system for supporting a patient and a robotic surgical manipulator. The robotic surgery system includes a base, a pillar coupled to the base at a first end and extending vertically upwardly to an opposing second end, and an attachment structure coupled to the second end of the pillar. A patient table is coupled to the attachment structure. A robot support arm has a first end coupled to the attachment structure. The robot support arm extends vertically upwardly from the first end to a second end. The robot support arm may further extend horizontally over the patient table to support a robotic surgical manipulator that will extend generally downward from the robot support arm toward a patient supported by the patient table to place an end effector of the robotic surgical manipulator adjacent a desired surgical site on the patient.
