A knotter, including: a driving structure; a punching and shearing clip, a clip mouth of the punching and shearing clip having a first position in an open state, and a second position in a punching state when driven by the driving structure; and scissor having a first position in an open state when driven by the driving structure, and a second position in a shearing state when driven by the driving structure. The second position of the scissor is synchronized with the second position of the punching and shearing clip. The disclosure effectively solves the problem that the shearing knife of the knotter in the related art is unstable when cutting the suture line.

An atrial appendage occluder capable of entering a half-released state by means of pushing a head-end fiber comprises: an occlude body (); a head-end control fiber (); and a tail-end control fiber (). A head end of the occluder body () is connected to one end of the head-end control fiber () by means of a head-end threaded bushing (). A tail end of the occluder body () is connected to one end of the tail-end control fiber () by means of a tail-end threaded bushing (). The tail-end control fiber () is in the form of a hollow column. The other end of the head-end control fiber () sequentially passes through the tail-end threaded bushing () and the tail-end control fiber (). The occluder body () is in a woven-net support structure, and has a shape preconfigured to match the structure of an atrial appendage after the occluder body () has been fully released. The occluder body () is in the form of a strip and disposed in an outer sheath () before being released. The occluder body () is in a half-release state after being pushed out of the outer sheath (). The diameter of the occluder body () is changed by pushing or pulling the head-end control fiber (). The atrial appendage occluder can adjust its location in the atrial appendage, such that the occluder can be released precisely in a preset location.

Disclosed are an auricle clamp () and a delivery device thereof. The auricle clamp () includes two parallel clamp arms (); and two springs () located at two ends of the parallel clamp arms () respectively and are used for connecting the two ends of the two clamp arms () to form a closed-loop structure and providing a clamping force enabling the two clamp arms () to be located close to each other; and at least one of the two clamp arms () is divided into a first segment and a second segment, and the first segment and the second segment are pivotally connected or connected via a flexible material. The delivery device includes a handle; a coupler () capable of rotating relative to the handle; an outer tube () connected with the coupler (), wherein the outer tube () rotates about a centre axis of the outer tube () with the rotation of the coupler (); a liner tube () capable of moving within the outer tube () along the centre axis of the outer tube (); a trigger (), which is connected to an end of the liner tube () close to the handle so as to push the liner tube () to move within the outer tube (); and upper teeth and lower teeth, which are connected to the liner tube () respectively so as to pivot relative to the outer tube () with the movement of the liner tube () within the outer tube () to facilitate the scissor-type opening and closing of the upper teeth and lower teeth.

Auricle clamp and delivery device thereof

The present disclosure discloses a knot-tying device and a knot-tying system with the knot-tying device. The knot-tying device comprises a shear knife provided at a front end of a driving rod. Hilts of the shear knife () are opened by an elastic member, and the hilts are pressed by the driving rod to close and cut a suture. The shear knife is used as a substitute for a cutter in the related art, and is driven to close by the driving rod so as to realize a shearing function. When the suture is cut off by the shear knife, a requirement for sharpness of blades are greatly reduced, and the blades are able to be realized by a common processing method, thereby greatly reducing cost while ensuring reliability. In addition, abrasion on the blades from the suture is reduced, thereby greatly prolonging the service life of the product.

Pulmonary artery stent

A control method, system and apparatus for flow detection, a controller and a detection device. The method includes the controller acquires a flow identifier of a flow to be detected by each flow detection module in a network; adjusts the flow to be detected by each flow detection module according to a set load balancing policy; and delivers a detection instruction to each flow detection module, where the detection instruction includes a flow identifier of a flow to be detected by each flow detection module after the adjustment. In the present invention, because multiple flow detection modules are deployed in a network in a distributed manner, when there are a large number of switching devices included in the network, load balancing can be performed for detection of flows transmitted between these switching devices.

A method and a device for synchronizing network data flow detection status are provided. The method includes: a status synchronizing server receives a first request sent by a first security device node, where the first request carries a first flow entry of a first data flow that is currently detected by the first security device node; determines first network data flow detection status corresponding to the first flow entry; sends a first response to the first security device node, where the first response carries the first network data flow detection status. A security device node requests previous network data flow detection status of a data flow from a status synchronizing server so as to synchronize network data flow detection status, thereby allowing the security device node to detect a network attack in a more accurate way and improving network system security.

Embodiments of the present invention disclose a method, an apparatus, and a system for establishing an FCoE communication connection and a name server. According to a WWN world wide name identifier of a target to be accessed, a destination MAC address used to access the target to be accessed is acquired. According to the destination MAC address, a login operation is performed for the target to be accessed, to establish an FCoE fiber channel over Ethernet communication connection, so that an FCoE initiator may directly establish a communication connection with an FCoE target, thereby reducing data transmission delay and lightening the processing load of an original FCoE forwarder.
