The first and second jaw members may be configured to move relative to each other between an open configuration and a closed configuration. The clip applier may also include a stabilizing member having an end portion secured to the first jaw member. The stabilizing member may be configured to engage a proximal portion of the surgical clip and be compressed from a first configuration when the first and second jaw members are in the open configuration to a second configuration when the first and second jaw members are in the closed configuration. The stabilizing member may have at least one bend that facilitates compression of the stabilizing member.

A cartridge system includes a clip unit including a clip having a plurality of arms; a case including an accommodation region in which the clip unit is accommodated; and a spacer that is accommodated in the accommodation region, wherein the spacer is configured to be separated from the clip unit when the clip unit is pulled to a proximal-end side of the cartridge system.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

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).

The present disclosure provides a multiple-processing device for an endoscope. The multi-processing device may comprise a plurality of processing units, a conveying component, and an operation component. The processing units may include a capsule body and clamping arms. A proximal end of the capsule body may be provided with a first limit part that may be available for deformation or failure under an external force. The distal end of a conveying pipe of the conveying component and/or the proximal end of the capsule body may be provided with a second limit part configured to expand and contract along a radial direction of the conveying pipe. The multiple-processing device not only enhances the combination between the capsule body and the conveying pip, so as to control the opening and closing of the clamping arms, but also prevents the processing units from interfering or jamming the inner wall of the conveying pipe due to the expanded first limit part, which can ensure the smooth movement of the processing units in the conveying pipe, so that the processing units can be effectively repeatedly opened and closed before being released. The present disclosure also provides a use method of a multi-multi-processing device for an endoscope.

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.

An occluder device is provided for occluding a cardiovascular defect or a gap between a medical device and adjacent body tissue, the device including a compliant balloon defining a fluid-tight balloon chamber and a balloon channel forming a longitudinal passage from a proximal to a distal side of the balloon, the balloon including a fluid port for filling a fluid into the balloon chamber. A tip and a base are coupled to the distal and the proximal sides of the balloon, respectively. At least one connecting strut is attached to the tip and to the base. An elongate actuator is disposed longitudinally slidable in the balloon channel and connected to the tip, and longitudinally slidable with respect to the base so as to set a distance between the tip and the base. A lock is configured to maintain the distance between the tip and the base. Other embodiments are also described.

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.

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.
