Description
Technical field
This utility model relates to a kind of mechanical kickoff mechanism of arterial blood tuberculation thromboembolism spring coil.
Background technology
The blood vessel embolism apparatus is widely used in diseases such as treatment cerebral artery vessel tumor.Hemangioma spring thromboembolism minimally-invasive treatment can be summarized as follows: the doctor feeds micro-wire, microtubular in the encephalic angioma through heart at first respectively by femoral artery (or carotid artery) under X-light radiography instructs.After micro-wire was drawn out of, microtubular just became hemangioma and external path.The doctor fastens the feeding of plug spring coil according to the size order with hemangioma and frees in hemangioma.The blood of intravasation tumor slows down because of hindered gradually by spring coil, solidifies, and is converted into stable glue unit tissue.The former tissue that at any time may disruptive hemangioma therefore be stabilized replaces, thereby has prevented that effectively hemangioma from breaking and cause the possibility of cerebral hemorrhage apoplexy.For the hemorrhage patient of hemangioma, hemangioma latch plug minimally-invasive treatment can effectively stop the further cerebral hemorrhage of hemangioma.General blood vessel embolism apparatus is the soft spiral winding that is formed by the tinsel coiling.Typing is processed into the secondary shape again.
The blood vessel embolism spring coil is to push hemangioma by pushing away silk by microtubular, and the thromboembolism spring coil needs to locate to disconnect with spring coil contact (main contact) pushing away silk, that is, free.Disconnecting the pusher silk extracts out by conduit.According to the needs of thromboembolism volume and density, the doctor can continue other thromboembolism spring coil to be pushed by microtubular and free in hemangioma.Generally need implant a plurality of blood vessel embolism spring coil intravasation tumors to the each patient.In the prior art, with electrolysis with spring coil with push away the terminal spring coil of freeing of silk, be with the spring coil tail end and push away a head end welding or weld and form.Push away silk by the rustless steel manufacturing, when the thromboembolism spring coil feeds human body, push away a head end (that is main contact place) and be exposed in the body fluid that solion is arranged, when impressed current, disconnect because of electrolysis.Also have and use the machinery of hook fastening mechanism to separate desorption method etc.The shortcoming that electrolysis is freed is: the time of 1) freeing is long, 2) main contact is a solid structure, microtubular can be released original position by recoil when the spring coil tail end is pushed out microtubular, thereby the operator can not accurately control the transfer position of spring coil and often need readjust the position of microtubular and hemangioma neck.The shortcoming that existing machinery is separated desorption method is: 1) moving in a big way can take place in main contact when freeing, thereby changes the thromboembolism spring coil, microtubular, and angiomatous relative position; Also may increase angiomatous compressing when serious even cause hemangioma to break.2) junction point (main contact) is difficult to make flexible structure, microtubular can be released original position by recoil when the spring coil tail end is pushed out microtubular, thereby the operator can not accurately control the transfer position of spring coil and often need readjust microtubular and angiomatous position.
