Disclosed in the present invention is an interventional system for an artificial implant. The interventional system for an artificial implant has a distal end and a proximal end which are opposite to each other, and, taken as a whole, has an axial direction when straightened and corresponding radial and circumferential directions. The interventional system comprises: a control handle having a top side and a bottom side which are opposite to each other in the radial direction, wherein the control handle has a use state in which the top side faces upwards, and the control handle is provided with a reference mark for indicating the use state; a catheter assembly having a proximal end connected to and controlled by the control handle; and an artificial implant provided with a first visualization mark and loaded to a distal end of the catheter assembly according to a preset included angle, wherein the preset included angle corresponds to a circumferential offset amplitude between the first visualization mark and the reference mark when the control handle is in the use state. The interventional system can achieve rapid registration and release of the artificial implant.

The present application relates to the technical field of artificial implant medical device surface modification and middle ear hearing reconstruction, and discloses a processing method for enhancing the fixing stability of an artificial auditory ossicle prosthesis, the prosthesis and application. The method comprises the following steps: after the surface of the auditory ossicle prosthesis in contact with the middle ear tissue is cleaned, a polydopamine layer is formed in a basic dopamine solution, then gelatin, hyaluronic acid or cellulose sulfate is connected to the surface of the polydopamine layer through a carbodiimide activation system to form a viscous functional layer, and the dry sponge-like structure is obtained through freeze-drying. The functional layer can quickly rehydrate and restore the adhesion state after contacting with human blood or tissue fluid, thereby improving the fixing stability of the artificial auditory ossicle prosthesis in the initial implantation stage and reducing the risk of displacement or dislocation.

The application relates to a compression sleeve set for guiding deformation of an artificial implant, comprising a supporting assembly including an auxiliary guide tube and an inner tube, the inner tube having a lumen for the auxiliary guide tube to pass through, one end of the auxiliary guide tube being provided with a coupling structure which can be exposed to the inner tube and establish a detachable temporary connection with the artificial implant; a guiding assembly including an outer tube and a guide cylinder which is connected to the outer tube in a docking mode, the guide cylinder having a guiding cavity which is gradually tapered towards the outer tube, the auxiliary guide tube driving the artificial implant to enter the outer tube via the guiding cavity, and the artificial implant being radially compressed under the action of the guiding assembly. The application can improve the loading efficiency of the artificial implant and reduce the operation difficulty by improving the components in the compression sleeve set and the auxiliary device and the adaptive method.

This application discloses a control mechanism, a locking mechanisms, an interventional delivery system, a control method, and a loading method for an artificial implant. The control mechanism includes a base, a pulling wire and a locking member, wherein the base defines a locking hole, the pulling wire includes a free end that can pass through, wind around, or be detached from the artificial implant. The locking member as a whole is located at a distal end of the base, and rotatably engages with the base to lock the free end of the pulling wire.
