Title:
CONVEYING APPARATUS CAPABLE OF REALIZING RAPID ELECTRICAL SEPARATION
Document Type and Number:
WIPO Patent Application WO/2022/142706
Kind Code:
A1
Abstract:
The present invention relates to a conveying apparatus capable of realizing rapid electrical separation. The conveying apparatus comprises: a conveying steel catheter, wherein an insulation catheter is sheathed on the proximal end thereof, a conductive catheter is sheathed on the outer side of the insulation catheter, and a support spring is connected to the distal end of the conveying steel catheter; the distal end side of the support spring is provided with a second cathode, and the second cathode is connected to the proximal end of the conveying steel catheter via a cathode conductive wire; the distal end side of the second cathode is provided with a second anode, the second anode is provided with a separation point, and the second anode is connected to the conductive catheter by means of an anode conductive wire; both the anode conductive wire and the cathode conductive wire run through the conveying steel catheter; the second anode, the anode conductive wire and the conductive catheter form a positive path and are connected to a positive electrode of an electrical separator; the second cathode, the cathode conductive wire and the proximal end of the conveying steel catheter form a negative path, and are connected to a negative electrode of the electrical separator; and the second anode and the second cathode conduct the positive path and the negative path by means of electrolyte in blood, so as to form a low-resistance loop. The separation point is subjected to electrochemical dissolution fracture to be separated from an implant, the separation time is short, and the stability is good.
