In some examples, a catheter includes an elongated body defining an inner lumen and comprising an expandable member disposed at a distal portion of the elongated body, and a rotatable cutting tool located within an inner lumen of the elongated body, the rotatable cutting tool configured to segment a thrombus into smaller pieces while an aspiration force pulls the thrombus proximally into the inner lumen. In some examples, the catheter further comprises an intermediate structure oriented radially between the rotatable cutting tool and an interior surface of the elongated body, the intermediate structure configured to prevent the cutting tool from contacting the interior surface of the elongated body. In some examples, a stopper is configured to limit movement of the cutting tool distally past a distal end of the expandable member.

A surgical bone-protecting drill guide device includes a body formed of biocompatible material forming a shell. The body includes an outer surface, an interior surface being a reverse-engineering surface approximation of a protruding boney structure of one or more bones in an image of a patient and body material between the outer surface and the interior surface. The device includes implant guides. Each implant guide is configured to extend from the outer surface and through the body material and the interior surface and provide a window to a pre-planned implant location for implanting a respective one implant relative to the protruding boney structure of the patient. The window has a size and shape that is pre-calculated as a function of a size of a pre-determined tool to be inserted through the window.

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.

An endoscopic surgical instrument includes a front slide, a scope coupler mounted on the front slide, a hammer pivotally mounted on the front slide, a cannula having a lumen and formed with a slot, a sleeve mounted to partially rotate on a portion of the cannula, a blade tube and a retractable cutting blade assembly having a cutting blade situated within the blade tube. The blade tube extends axially from the front slide. The tube is received by the lumen of the cannula. The blade 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 tip of 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.

A device for cutting soft tissues in the body, such as a transverse carpal ligament in a hand, includes a handle, a shaft, a cutting device on or in the shaft (e.g., a blade or radiofrequency electrodes), and a single expansion band or bowing flanges that bow out laterally to form a safe zone. The expansion band or bowing flanges is/are movable between an expanded configuration and a retracted configuration using a slidable actuator on the handle.

A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

A surgical stapling device includes a tool assembly having an anvil assembly, a cartridge assembly, and a drive assembly. The cartridge assembly includes a channel member that defines a recess and a staple cartridge that is releasably received within the recess of the channel member. The staple cartridge includes a cartridge body, staples, pushers, and an actuation sled that supports a knife. The drive assembly has a working member that is movable through the tool assembly to advance the actuation sled through the staple cartridge to actuate the tool assembly. The actuation sled of the staple cartridge includes a guard to shield the knife and minimize any likelihood of injury to medical personnel during installation and replacement of the staple cartridge.

A container holds at least one surgical implement, has a lock mechanism, and has a signature label that impedes access to the surgical implement until the correct surgical site is confirmed. A method of using the container includes the steps of confirming the correct surgical site, signing the label and removing it from the container, placing the label in the medical record, unlocking the container, removing the implement, and beginning the surgery, wherein the surgical team is forced to pause to confirm the correct surgical site before starting the surgery. The system and method may also include a wrong site surgery profile used by individuals within the surgical procedure environment and third parties for tracking and determining if, and where, a wrong site surgical procedure occurred. The profile can be updated, tacked and monitored while a patient is interacting within the medical environment.

Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.

An insertion device is disclosed. The insertion device includes a base portion, a top portion slidably connected to the base portion, an introduction needle, a catheter in slidable relation to the introduction needle, and a substantially cylindrical flash chamber, the flash chamber having an inlet in fluid communication with the introduction needle. The flash chamber is connected to the base portion, the top portion slidably engages with the flash chamber, and the catheter and the top portion slidably advance with respect to the introduction needle and the base portion.

A surgical tool arrangement for performing endoscopic surgical procedures which includes a powered handpiece and a surgical cutting accessory which detachably connects to the handpiece. The cutting accessory incorporates a cutting head for resecting tissue and a suction arrangement at the distal end of the cutting accessory closely adjacent the cutting head which suction arrangement serves to evacuate tissue from the surgical site and additionally serves as a cleaning mechanism for the surgical cutting accessory. The accessory additionally incorporates a bearing arrangement for supporting the cutting element as same rotates within the housing element.
