METHOD AND APPARATUS FOR COUPLING SOFT TISSUE TO A BONE
20230000484 · 2023-01-05 ·

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel.

Opthalmic microsurgical instrument
11564835 · 2023-01-31 ·

In some embodiments, a microsurgical instrument includes a trocar having a rigid, hollow shaft formed with a lumen extending from a proximal end to a distal end of the shaft. The distal end of the shaft may be shaped for tissue penetration. The instrument may further include a composite microcannula slidably engaged with the trocar in the lumen. The microcannula includes a light guide and a flexible hollow tube having an outer diameter less than an inner diameter of the lumen in the trocar. Other embodiments include placing the microcannula in the lumen of the trocar, illuminating the end of the trocar by illuminating the end of the microcannula, advancing the trocar from a selected entry point on an eye into a selected structure in the eye, and extending the illuminated end of the microcannula from the trocar into the selected structure.

TROCAR-CANNULA ASSEMBLY CAP

The present disclosure relates to trocar-cannula insertion tools for ophthalmic procedures. In certain embodiments, a cap for a trocar-cannula insertion tool includes a body having a proximal end and a distal end opposite the proximal end. A marking element extends in a distal direction from the distal end of the body and includes at least one marking tip for forming one or more indentations on a patient's eye during an ophthalmic procedure. A manipulation element extends from the body in a direction different from the marking element and includes at least one manipulation tip for gripping a tissue of the patient's eye during the ophthalmic procedure. In certain embodiments, the cap further includes at least one window for exposing a photoluminescent cannula of the trocar-cannula insertion tool to light, enabling the cannula to absorb photons prior to insertion thereof.

BALANCING FEATURE FOR REUSABLE TROCAR
20230225759 · 2023-07-20 ·

A surgical access device assembly includes a cannula hub and a cannula tube. The cannula tube extends distally from the cannula hub along a longitudinal axis. The cannula tube defines a working channel. The cannula tube includes a tissue engagement feature and a balancing feature. The balancing feature is configured to promote lateral stability of the cannula tube and the cannula hub relative to the body cavity wall of the patient. The balancing feature includes a proximal portion of the cannula tube having a first wall thickness. The balancing feature also includes a distal portion of the cannula tube having a second wall thickness that is greater than the first wall thickness. At least a portion of the proximal portion is proximal relative to the tissue engagement feature. At least a portion of the distal portion is distal relative to the tissue engagement feature.

System and method for video assisted percutaneous needle cricothyrotomy and tracheostomy
11559646 · 2023-01-24 ·

A system and method for video assisted percutaneous needle cricothyrotomy and tracheostomy to assist physicians in quickly intubating patients suffering from respiratory distress when oral or nasal intubation is not possible or contraindicated. The system and method includes a display monitor, a percutaneous needle assembly including a connection hub having a syringe port for removably attaching a syringe, a needle port for attaching a hollow needle, and a stylet port in communication with the needle port for receiving a fiber optic stylet that extends through the hollow needle. The fiber optic stylet includes one or more illuminators, and a camera for capturing and transmitting anatomical images for display on the display monitor to visually assist physicians in locating a patient's trachea lumen. The fiber optic stylet is positioned within the trachea lumen, and used as a guide wire to insert a dilator and cannula for ventilating the patient.

Angled surgical trocars
11696784 · 2023-07-11 · ·

Various exemplary angled surgical trocars and methods of using angled surgical trocars are provided. In general, a trocar configured to be advanced into a body of a patient can have an angled distal portion. The trocar can have a cut-out at its distal end in the angled distal portion of the trocar. The trocar can be advanced into the patient's body alone or with an obturator located therein. The obturator located in the trocar can have a flexible portion configured to bend within the trocar's angled distal portion. The trocar and obturator can be used in a variety of medical procedures, for example thoracic procedures in which the trocar is used to provide access to a thoracic cavity of a patient.

Instrument set for spinal operations
11547424 · 2023-01-10 · ·

A complete removal and reinsertion of instruments is avoided when the instruments are initially not correctly positioned during a minimally invasive operation on a bone, in particular a vertebra of the spine. This aim is achieved by an instrument set for spinal operations, including a guide rod, which has a cavity extending along the axis of the guide rod, and a guide tube, which can be received in the cavity of the guide rod, wherein the guide rod has a distal lip, which is arranged eccentrically to the cavity and/or to a center axis of the guide rod.
