Systems and methods are disclosed that include a guide catheter apparatus insertable through a external body passage of a subject. The guide catheter apparatus includes a substantially rigid shaft and a handle. The shaft has a proximal opening, a distal opening, and a lumen extending between the proximal opening and the distal opening. The handle has a structure to allow a position of the guide catheter to be controlled by some or all of three fingers of one hand of an operator of the handle. The structure of the handle is adapted to permit the operator to position a thumb and index finger of the hand to manipulate a working device inserted into the lumen of the guide catheter, where the working device is manipulable via a portion of the working device immediately adjacent to the handle.

An instrument system for treating a sinus of a subject includes an instrument including a base configured to be gripped by an operator, and an elongate probe including a probe proximal end coupled with the base and extending to a probe distal end. The probe includes an aspiration lumen terminating at an inlet port proximate the probe distal end, and a delivery lumen terminating at an outlet port proximate the probe distal end. The instrument also includes a waveguide on the probe and having a light emitting end proximate the probe distal end.

Delivery devices, delivery systems, and related methods, for precise administration of hemostatic compositions are disclosed, which may include a trigger mechanism, a pusher, a valve, and a cannula. The pusher is configured to engage with the trigger mechanism, retain a first syringe, a least by coupling with a plunger of the first syringe. The valve is fluidly coupled to the first syringe. The valve is further configured to engage with a second syringe, in fluid communication with both the valve and the first syringe. The cannula extends distally from and is fluidly coupled to the valve. Activation of the trigger mechanism causes the pusher and the plunger of the first syringe to translate in a distal direction, to expel a composition out of the first syringe, through the valve, through the cannula, and out of a distal end of the cannula.

User interface devices for manipulating a robotic surgical tool in a surgical robotic system are described. A user interface device can include a device body containing a tracking sensor to generate a spatial state signal in response to movement of the device body. The spatial state signal can be used to control a spatial motion of a surgical robotic system actuator. Several grip linkages can be pivotally coupled to the device body. A grip linkage displacement sensor may monitor movement of the grip linkages relative to the device body, and generate a grip signal in response to the movement. The grip signal can be used to control a grip motion of a robotic surgical tool mounted on the surgical robotic system actuator. Other embodiments are also described and claimed.

Provided are systems, apparatuses, and methods for performing minimally invasive spinal surgery. For example, provided is a minimally invasive surgical apparatus for securing a pedicle screw or lateral mass screw to a vertebral lateral mass or pedicle. The example apparatus includes an instrument portal, a pedicle screw or lateral mass screw reducer, an anchor pin receiving chamber, an anchor pin, and a handle.

A surgical stapler for stapling the tissue of a patient is disclosed. The surgical stapler comprises a handle, a shaft extending from the handle, and an end effector. The end effector comprises a tissue compression surface, a plurality of staples, and an anvil comprising staple forming pockets, wherein the anvil is movable toward the tissue compression surface during a closing stroke to clamp the patient tissue against and tissue compression surface. The surgical stapler further comprises an anvil closing system configured to move the anvil through the closing stroke, a staple firing system configured to deploy the staples during a staple firing stroke, and means for clamping and holding the patient tissue during the staple firing stroke and moving the end effector relative to the patient tissue after the staple firing stroke.

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. The surgical tool is constructed and arranged for use in conjunction with X-ray or ultrasound machines. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a bone or pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the wire be retracted, a jack member is included to allow the wire to be precisely retracted. The hand grip is securable to various surgical driving tools for the purpose of providing the ability to cooperate with various brands of pedicle screws and other surgical implants for spinal procedures.

A circular stapling device is described that is particularly suited for creating stomas. The circular stapling device includes two tool assemblies. The first tool assembly is adapted to create a reinforced incision in tissue, e.g., the rectus sheath, through which a vessel portion, e.g., colon, small intestine, etc. can be pulled through during a surgical procedure. The second tool assembly is adapted to attach a stomal sleeve within the vessel portion such that the stomal sleeve extends from the stoma.

The invention is directed to a surgical device which is externally used as aiming device that permits accurate placement of surgical wire to mend a supracondylar fracture. The device of the invention decreases operative time, risks of the re-dislocation through continuous manipulation, radiology exposure for both the patient and operation room staff, and to decreases anesthesia duration. It is also directed to surgical use of the device for repair of a supracondylar fracture and to methods for making it.

A specimen retrieval device includes outer and inner shafts. An end effector is supported on a distal end of the inner shaft and includes first and second arms that are configured to support a specimen bag. The first and second arms are movable via actuation of a handle between a proximal position wherein the first and second arms are retracted and a distal positon wherein the first and second arms are deployed and the specimen bag is positioned for receiving tissue. A release tube is disposed within a collar defined in the specimen bag and is configured to releasably engage respective first and second arms to provide stability when supporting the specimen bag and facilitate disengagement of the first and second arms from within the collar upon retraction of the first and second arms.
