This small-diameter endoscope surgical instrument comprises: an inner pipe 20 that has an outer diameter equal to that of a small-diameter endoscope 10 to be used, that is used for inserting the small-diameter endoscope surgical instrument into a body, and that is replaced with the small-diameter endoscope 10 after insertion thereof; a guide pipe 30 which is configured to have the small-diameter endoscope or the inner pipe inserted therethrough and which supports the small-diameter endoscope or the inner pipe so as to be movable in an axial direction; and a treatment pipe 40 which is configured to have the guide pipe inserted therethrough to support the guide pipe so as to be movable in the axial direction, and which has, at the leading end thereof, a treatment means such as an electrode, a blade, or a hook, wherein each of the small-diameter endoscope, inner pipe, guide pipe, and treatment pipe has an independent operation part at the proximate end thereof, and thus the rotation angle and the position in the axial direction thereof can be changed. The present invention enables, with a simple configuration, gripping or fixing of tissues, electrocautery, electrocoagulation, ablation, mobilization, separation, or traction of tissues, and further enables removal of blood clots, etc., stuck to a hook during surgery, and a sample extraction for biopsy.

The cage handle with an endoscope function of the present invention is equipped with a lens and an optical cable so that a surgeon can perform an interbody fusion cage surgery, viewing the image of the front of a cage accurately, clearly. Since a separate endoscope or X-ray is not used, the surgery can be performed more easily, efficiently, and economically.

The present invention relates to a surgery instrument set for single port spinal surgery, in which since a surgical instrument is inserted into an endoscope so as to secure a surgery space through a single port to perform surgery, an invasion may be minimized and a surgical instrument may be replaced with instruments having a variety of functions and shapes according to the purpose of surgery so as to reduce time consumed for the surgery. To this end, the present invention relates to a punch configured to form a treatment hole, an intubator inserted into the formed treatment hole and configured to secure a path, an endoscope inserted into the intubator and configured to secure a view of a surgery region, and a surgical instrument set including surgical instruments which are each replaceable with an adequate instrument according to the purpose and target of surgery and inserted into the endoscope to perform surgery and a method of using the same.

A trajectory guiding apparatus and one or more methods associated therewith for facilitating precision-guided alignment and implantation of a DBS therapy device in a patient. A base plate and base frame combination provides a platform for a dual-stage slider (DSS) assembly comprising a bottom stage slider (BSS) table and a top stage slider (TSS) table that each have suitably sized apertures or orifices therethrough for allowing the passage of and securely holding an instrumentation column (IC) assembly whose translational movement (i.e., sideways or forward and/or backward directions along a translational plane) and pivotal/rotational movement (i.e., around a perpendicular axis orthogonal to the translational plane and extending through a pivot or fulcrum) are independently controlled by respective slide actuators in order to properly align the IC assembly to a desired trajectory.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

A trajectory guiding apparatus and one or more methods associated therewith for facilitating precision-guided alignment and implantation of a DBS therapy device in a patient. A pivotally rotatable stage is pivotally coupled to a base support and a vertical support operative to support a slider assembly arranged to accommodate an instrumentation column (IC) containing the therapy device. A first gimbal drive is disposed between the pivotally rotatable stage and the base support, wherein the first gimbal drive is actuatable to cause a first pivotal motion of the slider assembly including the IC, the first pivotal motion defined along a first arcuate path pivoted around a first pivotal axis. A second gimbal drive is disposed between the pivotally rotatable stage and the vertical support, wherein the second gimbal drive is actuatable to cause a second pivotal motion of the slider assembly including the IC, the second pivotal motion defined along a second arcuate path pivoted around a second pivotal axis perpendicular to the first pivotal axis.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Instrumentation for microendoscopic surgery comprises a retractor system including a navigated initial probe, nested retractors and a navigated final tubular retractor defining an interior passage extending between a proximal end and a distal working end. A multi-planar navigation marker including a plurality of spaced-apart, radiopaque marker bodies can be mounted to the tubular retractor at a predetermined multi-planar spatial and rotational relation to the distal working end. The retractor can optionally include systems for fluid irrigation and suction with differential activation allows for the option of maintaining a dry surgical field or a submerged surgical field depending on the surgeon's preference during various portions of the procedure. The instrumentation can also include a camera for direct viewing and navigated burrs and/or navigated osteotomes, which allow the surgeon to use direct visualization and/or information from instrument localization on multi-planar images depending on surgeon facility resources.
