METHOD FOR OPERATING SURGICAL INSTRUMENT SYSTEMS
A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
HEMOSTATIC CLIP AND AUXILIARY SYSTEM
A hemostatic clip and an auxiliary system are disclosed. The hemostatic clip includes a first clip arm (110), a second clip arm (120), a tightening tube (140), a middle clip arm (150), an intermediate assembly (160), a traction assembly (170), a control handle (180) and at least two separators (190). The traction assembly (170) is connected to both the control handle (180) and the intermediate assembly (160), and the intermediate assembly (160) is connected to the tightening tube (140). Both the first clip arm (110) and the second clip arm (120) are proximally connected to the traction assembly (170). The middle clip arm (150) extends through the tightening tube (140) and is fixed proximally to the intermediate assembly (160). The first clip arm (110) and the second clip arm (120) are disposed on opposite sides of the middle clip arm (150). The first clip arm (110) makes up a first clip together with the middle clip arm (150), and the second clip arm (120) makes up a second clip together with the middle clip arm (150). The control handle (180) is configured to open or close the first clip and/or the second clip corresponding to the first clip arm (110) and/or second clip arm (120). The separators (190) are disposed in a lumen of the tightening tube (140) in such a manner that they are individually located between the first clip arm (110) and the middle clip arm (150) and between the second clip arm (120) and the middle clip arm (150), thus reducing the risk of device faults caused by interference of the first clip arm (110) and the second clip arm (120) with the middle clip arm (150).
Trans-esophageal aortic flow rate control
A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.
END EFFECTOR INSTRUMENT
Some embodiments of the present disclosure may provide an end effector instrument. The end effector instrument may include: an end effector device, the end effector device comprising an effector portion configured to perform a specified operation, and a delivery device connected to the end effector device, the delivery device being configured to deliver the end effector device to a target region where the specified operation is to be performed. The delivery device may include an operation portion. The operation portion may be configured to drive the effector portion to perform the specified operation.
Hemostasis reloadable clip release mechanism
A system for treating tissue includes a clip assembly including clip arms movable relative to a channel of a capsule so that the clip arms are movable between a tissue receiving configuration and a tissue clipping configuration. Also, the system includes an applicator releasably coupleable to the clip assembly. The applicator includes a bushing and a control member extending therethrough. The bushing includes deflectable fingers, each of the fingers including an engaging feature at a distal end thereof to engage a corresponding engaging feature of the capsule of the clip assembly and assembled with a pusher element configured to push the fingers to a radially outward position. The pusher element includes a U-shaped portion curving into a channel of the bushing and a longitudinal portion extending distally therefrom. A cam washer is slidable over a length of the control member and positioned distally of the U-shaped portion.
Surgical Instrument
A surgical instrument includes: a handle and a working head connected with the handle, in which the handle or the working head provides a power; a firing sleeve assembly detachably connected with the working head, in which a clip-jaw is provided on a side of the firing sleeve assembly far away from the working head; and a clip-cartridge assembly inserted into the firing sleeve assembly and detachably connected with the working head. The working head includes: a firing drive assembly for driving the firing sleeve assembly to achieve closing or opening of the clip-jaw, a clip delivery drive assembly for driving the clip-cartridge assembly to deliver a ligating clip, and a switching assembly for transmitting the power to the firing drive assembly or the clip delivery drive assembly.
REPOSITIONABLE OVER THE SCOPE CLIP
A clipping system includes an adapter configured to be mounted over an insertion device and a clip including first and second jaws movable between an insertion configuration and an initial deployed configuration. A first extending member is releasably coupled to the clip and movably connected to the adapter to permit a movement of the clip relative to the adapter from the insertion configuration to the initial deployed configuration. The first extending member is configured to permit withdrawal of the adapter away from the clip to place the system in a review configuration to enhance a visual observation of the clip. The first extending member is operable to retract the clip over the adapter so that the clip is forced open, freeing the clip from tissue on which it has been clipped. The first extending member is configured to release the clip therefrom in a final deployed configuration.
REPOSITIONAL CLIP WITH EXTENSION
A clipping system includes an adapter mounted on an insertion device and a clip including first and second jaws connected via hinges so that the first and second jaws are movable between an insertion configuration and an initial deployed configuration. A deployment member is configured to move the clip distally over and off of the adapter so that, as the clip leaves the adapter, the clip moves from the insertion configuration to the initial deployed configuration. An extending member is releasably coupled to the clip and movably connected to the adapter, and is configured to permit the withdrawal of the adapter away from the clip while the extending member remains coupled to the clip to place the system in a review configuration. The extending member is operable to retract the clip over the adapter, freeing the clip from tissue on which it had been clipped.
ENDOSCOPIC CLIP DEVICES AND RELATED METHODS FOR MUCOSAL DEFECT AND TRANSMURAL PERFORATION CLOSURE
An endoscopic clip device for closure of a mucosal defect or transmural perforation in a gastrointestinal wall may include a sleeve and a clip disposed at least partially within and coupled to the sleeve. The clip may be configured for reversibly moving between an open configuration for positioning relative to the wall and a closed configuration for closing the defect or perforation. The clip may include a first clip arm configured for engaging the mucosal and submucosal layers of the wall and including a first needle extending to a distal end of the first clip arm and configured for advancing through the mucosal layer and into at least the submucosal layer, and a second clip arm disposed opposite the first clip arm and configured for engaging the mucosal layer. The device may be configured for advancing through an operative channel of an endoscope or overtube having a tortuous shape.
Surgical clip applier and method of assembly
Surgical clip appliers are provided and includes a channel assembly extending distally from a housing; a clip carrier disposed within said channel assembly and defining a channel and a plurality of windows therein; a plurality of clips slidably disposed within said channel of said clip carrier; a wedge plate reciprocally disposed within said channel assembly, said wedge plate being operatively connected to said handles and including a plurality of apertures formed along a length thereof; and a clip follower slidably disposed within said channel of said clip carrier and disposed proximally of said plurality of clips, said clip follower being configured and adapted for selective engagement with said windows of said clip carrier and said apertures of said wedge plate. The clip follower is configured and adapted to urge said plurality of clips, in a distal direction relative to said clip carrier, upon reciprocal movement of said wedge plate.
