Release assembly, described release assembly is slidably disposed on supporting body, and described release assembly with described Frame bundled piece be connected, when discharge assembly slide backward relative to supporting body time, described release assembly by support bundled piece from from swollen Detach out on swollen support, so that self-expanding stent expands.

Operative site, the head of described supporting body is needed to be provided with target seeker further for facilitating entrance.

Further, the outer wall of described supporting body is provided with the self-expanding stent binding portion for bundling self-expanding stent Point.

Further providing a kind of release channel and the concrete structure of release assembly, described release assembly has release Silk, is provided with release channel in described supporting body, the outlet of described release channel is positioned at described self-expanding stent binding part Rear portion, described release silk is interspersed on release channel, and the head of described release silk passes from the outlet of described release channel Outside supporting body, and bundled by described support bundled piece with described self-expanding stent.

Further, described release assembly also has release lever, and described release lever is connected to discharge the tail end of silk.

Further, the afterbody of described supporting body is provided with operation handle.

Further, the seal wire duct of interspersed seal wire in being provided with it in described supporting body.

Further, the outer wall of described supporting body is additionally provided with graduation mark.

Further for the position observed when advancing operative site, described self-expanding stent is that the self-expanding of band development is propped up Frame.

Further, described support bundled piece is lashing wire.

After have employed technique scheme, this support release only has a bearing part, self-expanding stent is installed on and holds In holder, with the fixing self-expanding stent of support bundled piece binding, it is simple to the release of self-expanding stent, at binding self-expanding stent Placing a release silk, when self-expanding stent is downloaded to diseased region, as long as pulling release silk, support bundled piece unclamps simultaneously, Self-expanding stent swells naturally, and self-expanding stent is placed complete, the most only need to release release, this makes it possible to make support Off-position is accurate, and support release quickly, improves the convenience of operation.

Detailed description of the invention

In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached Figure, is described in further detail this utility model.

As shown in figs. 1 to 6, a kind of support release, it includes:

Supporting body 7；

Self-expanding stent 3；

Support bundled piece 2, self-expanding stent 3 is compressed on the outer wall of supporting body 7 and will be from swollen by described support bundled piece 2 Swollen support 3 is bundled on supporting body 7；

Release assembly, described release assembly is slidably disposed on supporting body 7, and described release assembly with described Frame bundled piece 2 is connected, when discharging assembly and sliding backward relative to supporting body 7, described release assembly by support bundled piece 2 from from Detach out on expanding stent 3, so that self-expanding stent 3 expands.

As it is shown in figure 1, the head of described supporting body 7 is provided with target seeker 1.The setting of target seeker 1 makes support release energy Enough convenient entrance operative sites.

As it is shown in figure 1, be provided with the self-expanding stent bundle for bundling self-expanding stent 3 on the outer wall of described supporting body 7 Tie up part.

As it is shown on figure 3, described release assembly has release silk 4, in described supporting body 7, it is provided with release channel (11), institute The outlet 5 stating release channel (11) is positioned at the rear portion of described self-expanding stent binding part, and it is logical that described release silk 4 is interspersed in release On road (11), and the head of described release silk 4 passes to supporting body 7 from the outlet 5 of described release channel (11), and and institute Stating self-expanding stent 3 to be bundled by described support bundled piece 2, the import of shown release channel (11) is positioned at supporting body 7 On tail end.

As it is shown in figure 1, described release assembly also has release lever 9, described release lever 9 is connected to discharge the tail of silk 4 End, the setting of release lever 9 facilitates operator and operates release assembly.

As it is shown in figure 1, the afterbody of described supporting body 7 is provided with operation handle 8, the setting of operation handle 8 facilitates operation Person operates supporting body 7.
