FLUID TRANSFER DEVICE
The present application provides a device (100) for transferring a fluid from a surgical site, comprising an elongate body portion (102) defining a proximal end region (106) connectable to a source of negative pressure; an elongate neck portion (104) defining a distal end region (108) of the device locatable at a surgical site; a through bore (118) extending from the distal end region to the proximal end region; and a control member (116) for selectively controlling a negative pressure at the distal end region, wherein the control member comprises a valve portion (124) configured to at least partially restrict a fluid flowing along the through bore when moved from an open position towards a closed position. A system including the device for transferring a fluid from a surgical site is also provided.
Combination suction and irrigation hand tool
An irrigation fluid dispensing tool well suited for use in a combination suction and irrigation tool has a frame carrying a surge flow pump formed of a flow controller of a manipulable handgrip of the tool handle, compressible irrigation fluid reservoir, and frame where the flow controller preferably is formed of a handle lever of the handgrip that is displaceable, preferably pivotable, between one or more of a surge flow actuation position, flow obstructing actuation position, and flow initiating position. The lever actuates a valve, preferably a pinch valve, when displaced toward the flow obstructing actuation position. The lever actuates the surge pump by compressing the reservoir, preferably squeeze bulb, against the frame when the handgrip is squeezed. The lever can be assembled to the frame in a protective shipping and storage position and is movable to a tool operating position providing irrigation fluid flow control during tool operation.
A Disposable Flushing and Suction Drainage Tube and Its Operation Method
A disposable flushing and suction drainage tube and a-using method thereof comprises a flushing tube, a suction tube, and a mounting base. The flushing tube and the suction tube are respectively mounted at one end of the mounting base, and an air connector and a water connector are mounted at the other end; the mounting base comprises a tube body base and a control base, the flushing tube and the suction tube are mounted at one end of the tube body base, and the other end is detachably connected to the control base. The disposable flushing and suction drainage tube controls suction for the suction tube by a negative pressure adjusting opening on the mounting base; opening, closing, and water flow of the flushing tube is controlled by a water control switch on the mounting base, and switching between flushing and drainage and the flow of drainage can be controlled.
DEVICES AND METHODS FOR MANAGING CHEST OR WOUND DRAINAGE
Devices and methods for managing chest or wound drainage are disclosed where in one embodiment, the system generally comprises a chest tube configured for insertion at least partially within a body of a subject, a drainage tube fluidly coupled with the chest tube, a reservoir fluidly coupled with the drainage tube, a pump in communication with the reservoir, and a controller in fluid communication with the drainage tube. The controller may be configured to determine a readiness for removal of the chest tube from the body based upon one or more removal parameters which are obtained over a period of time via the controller.
Anti-clog suction tip apparatus and methods
Various forms of anti-clog suction tips apparatus are disclosed. An exemplary anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.
Anti-clog suction tip apparatus and method
An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.
ASPIRATION THROMBECTOMY SYSTEM AND METHODS FOR THROMBUS REMOVAL WITH ASPIRATION CATHETER
A method of operating an aspiration catheter having a proximal end and a distal end includes the acts of at least partially blocking the distal end of the aspiration catheter with an embolus, creating a vacuum at the distal end of the aspiration catheter with a vacuum source adjacent the proximal end of the aspiration catheter, at least partially relieving the vacuum at the distal end of the catheter by at least one of interrupting the vacuum from the vacuum source and venting the aspiration catheter with a vent fluid adjacent the proximal end, and repeating the acts of interrupting the vacuum and venting the aspiration catheter in a timing cycle that maximizes the time that the aspiration catheter is at vacuum and changes pressure at the distal end of the catheter from vacuum to at least atmospheric pressure during each cycle.
OCULAR SURGICAL WORK TIP ADAPTER
An adapter for a surgical hand piece with a single lumen work tip converts the handpiece to infusion/aspiration (I/A) cleanup of lens epithelial cells in the capsular bag of the eye a patient after phacoemulsification. The adapter is in the form of a sleeve whose proximal end is to be joined to the distal end of work tip. The sleeve also has at least one aspiration hole located toward the distal end of the sleeve.
TRACKED SUCTION TOOL
A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.
Variable aspiration control device
An aspiration control device may include a conduit having a distal end and a proximal end and defining a conduit lumen, wherein the conduit defines a vent that is open to the conduit lumen, a coupling configured to couple the proximal end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula, a sleeve movably disposed about the conduit and configured to move relative to the vent to achieve a desired level of vacuum delivered to the inner cannula.
