The present invention provides a delivery device for medical implants. The delivery device has a detachable structure and includes a handle () and a catheter assembly () that are separated from each other. The handle () and the catheter assembly () are connected by a transmission shaft (). By configuring the handle () and the catheter assembly () to be separated from each other, the catheter assembly () has less weight than that of a traditional delivery assembly, so that the operator can position the medical implant and adjust the position of the medical implant by moving only the catheter assembly (). The catheter assembly () is lighter in weight and smaller in size, which improves the stability, precision and accuracy of the operation. Moreover, the impact of vibration and/or movement of the handle () on the catheter assembly () are avoided, which further improves the stability and thus the quality of the operation.

Medical implant conveying device

A delivery device (') for loading, delivering and deploying an implant () includes a handle (), an inner tubular core (), a sheath tube () and a guide tip (). The inner tubular core () is coupled, at a proximal end thereof, to an inner tubular core actuation member arranged in the handle (), and the guide tip () is disposed at a distal end of the inner tubular core () and fixedly connected to a distal end of the sheath tube (). The sheath tube is () sleeved over the inner tubular core (). Here, the proximal end of each component refers to the end thereof closer to the handle (), while the distal end thereof is the end farther away from the handle (). As the sheath tube () is fixedly connected, at the distal end thereof, to the guide tip (), the implant () is loaded at the proximal end of the sheath tube () in the delivery device (′). During deployment of the implant (), the sheath tube () is caused to move toward distal end, that is, the sheath tube () continues moving toward a target site for the implant (), rather than moves backward to the handle (). This can effectively avoid the problems that may arise from retraction of the sheath tube () through a three-dimensionally curved path, such as unstable or even faulty deployment of the implant (), thus allowing deployment of the implant () with enhanced quality.

Delivery device

A balloon dilation catheter, a balloon () and preparation method therefor. The balloon () is prepared by co-mixing at least two of L25, TR55, TR90, and TR70, and has high puncture resistance and low compliance with respect to a balloon () made of a single nylon material. The balloon () is preferably a hollow multilayer structure, and the puncture resistance of the balloon () can be further improved and the compliance can be further reduced with respect to a single-layer structure.

A slow-motion video shooting method includes detecting that a preset motion occurs on a main object in a video stream; determining a first video clip in the video stream based on the preset motion; determining a first frame rate based on the preset motion; and processing the first video clip based on the first frame rate to obtain a second video clip, where a play time of the second video clip at a target play frame rate is greater than a collection time of the first video clip, and the first frame rate is greater than the target play frame rate. When a main object for shooting moves, the first video clip, for example, a highlight clip, is obtained from the video stream, so that an electronic device can accurately capture a highlight moment of the main object.

A vertical synchronization signal-based control method. The method includes the electronic device draws a first layer of a first application in response to a first vertical synchronization signal, and buffers the first layer to a first buffer queue. The electronic device performs, in response to a second vertical synchronization signal, layer composition on the layer buffered in the first buffer queue, to obtain an image frame. The electronic device adjusts a signal period of the first vertical synchronization signal to first duration if a quantity of layers buffered in the first buffer queue is less than a first preset threshold, where the first duration is less than a signal period of the second vertical synchronization signal.

A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.

A cardiac valve prosthesis, comprising: an expandable valve support provided with multiple fixing holes, an artificial valve provided on the valve support, and a thorn structure comprising an expandable thorn support and multiple thorns. The multiple thorns are provided on the thorn support, and are used for, when the cardiac valve prosthesis is implanted into a cardiac chamber, passing through the multiple fixing holes and penetrating tissue in the cardiac chamber so as to fix the valve support. The thorn structure and the valve support are provided independent of each other so that separate manufacturing and processing thereof can be achieved, and the thorn structure and the valve support work together in a non-connected manner so as to facilitate step-by-step load and release, such that the size of a delivery catheter and the length of the valve support can be effectively reduced, the risk of breakage is reduced, and it also facilitates recovery when the cardiac valve prosthesis is not released in place.
