A device includes a handle, an apparatus for probing and cutting, and an adaptor. The handle includes one or more triggers. The apparatus for probing and cutting is connectable to the handle and includes an elongated member, a probe, and a blade. The probe and the blade are selectively deployable from the elongate member via activation of the one or more triggers on the handle. The adaptor is configured to selectively connect the apparatus to the handle in a predetermined orientation.

An endoscopic surgical instrument includes a main body assembly, and a cannula having a lumen and formed with a slot. An inner tube, which houses a spring-biased retractable cutting blade assembly having a cutting blade, is mounted on one end of the main body assembly and extends axially therefrom. The tube is receivable within the lumen of the cannula, and may be particularly oriented within the cannula lumen such that the cutting blade may be caused to project from both the tube and the cannula slot. The inner tube has a bore in which the distal end of an endoscope may be received. The instrument may be locked in one position to allow the endoscope to engage the blade assembly and cause the cutting blade to project from the cannula slot during a tissue cutting procedure, or may be locked in another position wherein the cutting blade remains retracted.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

An endoscopic surgical blade having a low-profile design, with an upper cutting surface and a lower cutting surface at its distal end and having a non-cutting radiused surface at the top end of the upper cutting surface, and the upper cutting surface and lower cutting surface meet at a crotch therebetween is disclosed. The blade is part of an endoscopic knife assembly which also contains a hollow knife tube hollow that allows the insertion of an endoscope for viewing of the surgical procedure. The endoscopic knife assembly can be used for in endoscopic surgery by insertion of the assembly through a slotted cannula. A method for a performing an operative procedure on a target tissue in a subject using the endoscopic knife assembly having a low-profile blade with an upper cutting surface and a lower cutting surface is also described.

The present invention relates to a surgical cutting instrument for minimally invasive surgery comprising a gripping element, a hollow stem mounted as an extension of said gripping element along a longitudinal axis of the instrument; a tie rod housed in the hollow stem and having a proximal end coupled to a control lever in said gripping element and a distal end hinged to a blade element; a covering and guiding sheath for said blade element as an extension of said stem. The blade element has a fulcrum that is movable in said covering and guiding sheath and is configured to pass from an inactive position in which it is hidden housed in said covering sheath and an active position protruding outwardly through a window of said covering sheath and vice versa.

A clamping arthroscopic resection tool is provided. The clamping arthroscopic resection tool includes a first jaw and a second jaw positionable on opposing sides of a tissue, a clamping structure which biases the first jaw and the second jaw against the tissue to clamp the tissue between the first jaw and the second jaw, an indicator mark disposed along one of the first jaw and the second jaw at an intermediate location, and a cutting member which is movable between the first jaw and the second jaw and between a non-cutting position and a cutting position to cut the tissue up to the indicator mark.

Some embodiments provide a soft tissue device, such as a transverse carpal ligament cutting device having one or more balloons that are deflated when the device is in an inactive position and are inflated when the device is in an active position. Other embodiments provide a soft tissue cutting method, such as a method of cutting a transverse carpal ligament that uses a soft tissue cutting device.

A device for dividing a fibrous structure comprising a catheter; an expandable member positioned near a distal end of the catheter and in fluid communication with a lumen of the catheter; and a cutting element situated on an outer surface of the expandable member. A method for dividing a fibrous structure comprising positioning, proximate the fibrous structure, an expandable member having a cutting element situated thereon; expanding the expandable member outwards to tension the fibrous structure across the cutting element; and activating the cutting element to weaken or cut the fibrous structure. A method for treating carpal tunnel syndrome comprising inserting a needle into the carpal tunnel; directing a guidewire to a position proximate the transverse carpal ligament; advancing, along the guidewire, a device having an expandable member and a cutting element; positioning the cutting element; tensioning the ligament across the cutting element; and weakening or cutting the ligament.

A Carpal Tunnel Release (CTR) surgical tool is disclosed. The CRT tool is useable to perform CTR surgically endoscopically through an incision in the patient, and includes dedicated optical components within the tool. The tool also includes wireless communication means to broadcast video images from the camera to an external display without the use of any cabling. The CTR tool is modular, thus allowing different portions of the tool to be replaced, including a blade tip assembly. The CTR tool is comprised of components manufactured of materials that can be cleaned and sterilized using an autoclave alone, which allows the tool to be more easily and cheaply used in subsequent surgeries, and in contexts that may lack the resources and support traditionally necessary for surgery. The CTR system may simply comprise of the tool (and its cheaper replacement parts), a monitor having wireless capability, and a simple autoclave.

The present disclosure describes a subcutaneous cutting device for insertion into tissues and cutting of targeted tissues. The cutting device includes a handle, a cannula extending distally from the handle to a sharpened distal tip, and an adjustable blade disposed within a blade-holding section of the cannula. The blade is selectively adjustable between a retracted position within the cannula and an open position with the blade tip lifted up and angled away from the cannula. When the blade is in the open position, the blade tip points proximally toward the handle.
