Surgical procedures using instrument to boundary spacing information extracted from real-time diagnostic scan data

The present disclosure is directed to improved phacoemulsification procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance concerning the distance separating a working end of a phacoemulsification instrument and the posterior capsule of the eye during a surgical procedure involving the removal of the crystalline lens of an eye. Such information is implemented to aid the surgeon in cutting or scoring the lens to a desired depth while minimizing the risk of penetrating the posterior portion of the capsule with the working end of the instrument. Some embodiments provide for the visual and / or auditory conveyance of distance information to the surgeon. Additional embodiments can provide for overlaying visual representations of selected structure information with the images provided to the surgeon.

Multifunctional forceps set and loop ligature co-used therewitn

A multifunctional forceps set which integrates two important surgical procedures of incision and ligation into a continuous working procedure. The forceps set is co-used with two loop ligatures formed of braided sutures and transfigured from a surgeon's knot. In use, the loop ligatures are side by side loaded in the forceps mouth of the forceps and controlled by the forceps to minify the size of the loop and accomplish ligation function. The forceps set is developed from consolidation of surgical scalpel, forceps and device simulating finger's functions. Also, the forceps set can rapidly perform the procedures of double grasping, incision between grasping, proper ligating divided pedicles and cutting residual sutures of post-ligation. The forceps set enables surgeons to use familiar technique in a challenging operative field such as endoscopic surgery.

Surgical Procedures Using Visual Images Overlaid with Visual Representations of Selected Three-Dimensional Data

Embodiments of the invention are directed to improved surgical procedures such as ophthalmic procedures that utilize overlaid visual representations of three-dimensional data or other data with direct or indirect visual images of a surgical region (e.g. the eye) to provide improved information to a surgeon to speed surgical procedures and / or to provide improved outcomes of those procedures. In some embodiments, ophthalmic procedures are combined cataract removal and astigmatism reduction procedures. In other embodiments the ophthalmic procedures are corneal refractive surgical procedures that reshape the cornea to reduce astigmatism or other aberrations. In some ophthalmic procedures the three-dimensional data is topography data associated with the anterior surface of the cornea. In some embodiments, the three-dimensional data may be enhanced or replaced with aberrometric data associated with the optical path of the eye.

Spinal Curvature Modulation Systems and Methods

Spinal curvature modulation systems, methods and related devices and instrumentation are disclosed, which include a flexible tether, a tether tensioning unit and bone anchors for the flexible tether that allow the tether to be secured across multiple vertebrae in a region of treatment. When the flexible tether is attached to multiple vertebrae, it can be used to correct spinal deformities. Tension in the flexible tether is adjustable transcutaneously without invasive surgical procedures by use of remotely driven actuators, such as a magnet-driven motor, or by a small tool insertable through a small incision. Disclosed systems and methods thus allow for multiple adjustments of tether tension, and spinal curvature, over time without repeated, highly invasive, spinal surgeries.

Computer Vision Based Method And System For Evaluating And Grading Surgical Procedures

To increase the timeliness, objectivity, and efficiency in evaluating surgical procedures such as those performed by ophthalmology residents' learning of cataract surgery, an automatic analysis system for surgeries such as cataract surgery is provided to assess performance, particularly in the capsulorrhexis step on the Kitaro simulator. Computer vision technologies are employed to measure performance of this critical step including duration, centrality, circularity, size, as well as motion stability during the capsulorrhexis procedure. Consequently, a grading mechanism is established based on either linear regression or non-linear classification via Support Vector Machine (SVM) of those computed measures. Comparisons of expert graders to the computer vision based approach have demonstrated the accuracy and consistency of the computerized technique.

Intravascular deliverable stent for reinforcement of vascular abnormalities

A stent / graft especially designed to be used in a minimally invasive surgical procedure for treating an abdominal aortic aneurysm (AAA) comprises an innermost tubular structure of a length (L1) formed by braiding a relatively few strands of shape memory alloy wire. The pick and pitch of the braid are such as to provide relative large fenestrations in the tubular wall. A portion of the innermost tubular structure of a length L2<L1 is surrounded by a further braided tubular structure having relatively many strands that occlude the fenestrations of the innermost tubular structure. The composite structure can be stretched to reduce the outer diameter of the stent / graft, allowing it to be drawn into a lumen of a delivery catheter. The catheter can then be advanced through the vascular system to the site of the AAA and then ejected, allowing it to self-expand with the portion L2 bridging the aneurysm. The portion L1>L2 does not block blood flow to the renal arteries while the portion L2 prevents the aneurysm to grown and burst.

Method for determining patient suitability for a surgical procedure

A system and method for determining a patient's suitability for a proposed surgical procedure is disclosed in which a simulated, procedure specific hemodynamic profile of an individual patient is obtained using a hemodynamic simulation module operating on a digital processor using a patient specific hemodynamic calculation parameter set. This is used by a trained clinician to evaluate whether the patient is a suitable candidate to undergo the proposed surgery. The patient specific hemodynamic calculation parameter set is obtained by optimizing a generic hemodynamic calculation parameter set. Optimization is done automatically by adjusting the generic hemodynamic calculation parameter set based on the comparison of simulated profiles corresponding to measured hemodynamic profiles of the patient in a non-operation situation. The automatic adjustment is guided by a Damped Least Squares Method and related algorithms.
