Abstract
The utility model designs a blood vessel inner support frame used in the operation, including a metal support frame with a composite film and a transmission device with a transmission component; the transmission device includes a bushing and a tubular handle connected with the bushing; the metal and the transmission component match each other and are connected with the far end of the bushing in a dismounting way. The support frame for operation of the utility model is simple in structure, convenient in use and reliable in work; the device can keep good geometrical shape; the physical properties are good; the biocompatibility is good. The utility model can not only finish two operations at one time, but also shortens the operation time at one time. The device is applicable to the overall interlayer aneurysm surgical treatment of the aortic pathological changes.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, uses endovascular stent in particularly a kind of operation.
Background technology
In existing medical skill, (comprise ascending aorta to suffering from whole aorta, bow portion, descending aorta and ventral aorta) patient of pathological changes all adopts center open chest surgery treatment, rise with artificial blood vessel, bow portion replaces and also send into one section artificial blood vessel (being commonly called as trunk) in the descending aorta section, for second operation or secondary interventional therapy (multiple membrane support implantation) are prepared.So once operation can not be finished treatment.Second operation will be opened breast under left rib, cause the bigger misery of patient, and spin out treatment cycle, increases risk; Secondary interventional therapy expense is expensive and certain linking difficulty arranged.
Summary of the invention
This utility model technical issues that need to address are to use endovascular stent in a kind of operation of design, to satisfy the needs of medical field.
The technical solution of the utility model:
Use endovascular stent in a kind of operation, or title stent-type artificial blood vessel, comprise metal rack that is provided with multiple film and the conveyer device that is provided with transfer member, said conveyer device comprises sleeve and coupled piped handle, and metal rack matches with transfer member and releasably is connected in the telescopic far-end.
Said metal rack can adopt the medical elastic alloy as CoCr alloy such as 3J21; NiTi marmem, or 316L/317L rustless steel, its structure can make Z-shaped structure, also can adopt braiding structure.Support can be made unidirectional or multi-direction bending, to adapt to crooked blood vessel.
Said compound membrane material adopts doctor's macromolecular material, as terylene, and polyamine fat, politef etc.This material is identical with common artificial blood vessel, can make corrugated surface garden column, also can be used as straight garden column.
Art medium-height trestle of the present utility model is simple in structure, easy to use, and reliable operation can keep good geometry, and physical property is good, good biocompatibility.It not only makes two operations once finish, and has shortened the once time of operation.Be applicable to the dissecting aneurysm operative treatment of whole aorta pathological changes.
Description of drawings
Fig. 1 is the support of stay-supported conveyer device.
Fig. 2 is the support of propelling movement type conveyer device.
Fig. 3 is an I type dissecting aneurysm art medium-height trestle operative treatment sketch map.
The specific embodiment
Fig. 1 uses endovascular stent in the operation of stay-supported conveyer device, comprises the metal rack 1 that is provided with multiple film, the conveyer device that is provided with transfer member;
Said conveyer device comprises sleeve 2, piped handle 3, and handle 3 is connected with an end of sleeve 2;
Said transfer member comprises stainless steel silk 4 and surgical thread 5, surgical thread 5 is bundled into slice with metal rack 1, stainless steel silk 4 passes handle 3, sleeve 2 and is bundled into the metal rack 1 of slice with surgical thread 5, the part that surgical thread 5 is tied up metal rack 1 is twined mutually with the stainless steel silk 4 that passes wherein simultaneously, the other end of surgical thread 5 is connected with handle 3, and the head of metal rack 1 releasably inserts sleeve 2.
The head of stainless steel silk 4 is provided with annulus 7, so that pull.
During use art medium-height trestle 1 is sent in the blood vessel from the blood vessel otch, it is fixing to arrest handle 3 on the other hand, and another hands is pulled out stainless steel silk 4, and support 1 just automatically springs open in blood vessel.
Fig. 2 is the support of propelling movement type conveyer device.Comprise the metal rack 1 that is provided with multiple film, the conveyer device that is provided with transfer member.
Said conveyer device comprises: sleeve 2, piped handle 3 and push rod 6, and handle 3 is connected with an end of sleeve 2, and said transfer member comprises push rod 6, and push rod 6 is inserted piped handle 3 and sleeve 2 slidably, pack into the far-end of sleeve 2 of support 1.
To withstand support 1 with push rod 6 in the sleeve 2 insertion blood vessels during use, the fixed position, with sleeve 2 recession, support 1 just discharges and flicks from the epitheca pipe.
After art medium-height trestle 1 flicks, the film of support head and the artificial blood vessel or the tissue at other positions can be sewed up, finish whole operations.
Fig. 3 is an I type dissecting aneurysm art medium-height trestle operative treatment sketch map.
With the art medium-height trestle I type dissecting aneurysm patient is implemented operation, use the cochrome support, ripple tubular dacron membrane is used the stay-supported mode of movement.What patient suffered from is I type dissecting aneurysm.Must make full bow replaces.Ascending aorta and bow portion have done artificial blood vessel's replacement in the operation, send into the art medium-height trestle from descending aorta blood vessel incision, and support automatically springs open, and then art medium-height trestle proximal part edge and artificial blood vessel are sewed up.Postoperative is good through the molding of contrast examination blood vessel, ne-leakage.
