In another embodiment, actuation part 112 also has engaging portion 1122 (as shown in Figure 1B), can be separately positioned on the
On one actuating unit 1124a and the second actuating unit 1124b, for combining an effect force applicator 2.Please refer to figure
1E is sleeved on the engaging portion 1122 of actuation part 112 through by the positioning region 21 for acting on force applicator 2, and user can pass through behaviour
Making portion 22 is the application active force of actuation part 112, so that the first actuating unit 1124a and the second actuating unit 1124b stress, and enable
Clamping part 111 is in pre- clamp position.Furthermore the positioning region 21 for acting on force applicator 2 can be relative to the engaging portion of actuation part 112
1122 are rotated, with the angle between adjustment effect force applicator 2 and clamping ontology 11, thus best convenient for users to finding
Position is operated.
In addition, as referring to figure 1E, since effect force applicator 2 has extended operation portion, user can pass through work
Clamping ontology 11 operated in the external of patient with force applicator 2.
Please refer to Fig. 1 D, for the side view of the clamping external member 12 of the first embodiment of display the application.As schemed
Show, clamping has the second positioning region 121 in external member 12, wherein when clamping part 111 is clamped in blood vessel or blood vessel and surrounding group
When knitting, clamping external member 12 can be sheathed on clamping part along the first surface 1111a and second surface 1111b of clamping part 111
On 111, and by making to clamp the second positioning region 121 of external member 12 and appointing in multiple first positioning regions 1112 of clamping part 111
Meaning one match so that clamping external member 12 be located on clamping part 111, wherein can by make the second positioning region 121 from it is different
The first positioning region 1112 cooperate, with adjust clamping external member 12 and clamping part 111 relative position, and then adjusting clamping part
111 chucking powers applied.
Please refer to Figure 1A, in this present embodiment, when the second positioning region 121 is positioned on clamping part 111 further away from cause
When on first positioning region 1112 in dynamic portion 112, then clamping part 111 under the action of clamping external member 12, get over by the chucking power applied
It is small；Conversely, when the second positioning region 121 is positioned on clamping part 111 on the first positioning region 1112 of actuation part 112,
The chucking power that then clamping part 111 is applied is smaller, and user can clamp external member 12 by adjusting according to actual demand as a result,
With the relative position of clamping part 111, blood vessel or blood vessel and surrounding structural clamping are clamped in adjust clamping part 111
Power.
In this present embodiment, the second positioning region 121 may be designed as the band shape matched with the first positioning region 1112.
Interlocked by the band of the first positioning region 1112 and the second positioning region 121, and can opposite sliding or locking.In addition, clamping external member
12 can be as made by deformable material, and clamping external member 12 may be designed as U-shaped folder, torsional spring or elastic piece (as shown in Figure 3).
Please continue to refer to Fig. 1 D, in an embodiment, clamping external member 12 holds portion 122a with first set and second set is held portion
122b, and first set holds the length of portion 122a and is greater than second set of length for holding portion 122b.It is corresponding please refer to Figure 1B,
Portion 113 is worn in being additionally provided with first on clamping ontology 11, may be disposed at first surface 1111a or second surface 1111b its
On middle one, in this present embodiment, first wear portion 113 be arranged on first surface 1111a close to actuation part 112 one
One boss at end, wears in first and is additionally provided with the first perforating 1131 in portion 113, will clamp longer first in external member 12
Set holds portion 122a as fixed arm, and is arranged in the first perforating 1131 and carries out axial shifting relative to the first perforating 1131
Dynamic (as shown in Figure 1A), so as to the relative position of adjustment clamping external member 12 and clamping part 111, and wearing portion 113 by first can
Clamping external member 12 is connected on clamping ontology 11, to be user-friendly for operating.
In this present embodiment, the first perforating 1131 may be configured as the non-circular shape such as rectangle, triangle, ellipse,
This measure is that it is opposite can to limit clamping external member 12 in order to make first set hold portion 122a after being arranged among the first perforating 1131
It is circumferentially rotated in clamping ontology 11, that is, only allows to clamp external member 12 and moved along the axial direction of clamping ontology 11,
But it can not be circumferentially rotated relative to clamping ontology 11, so that can keep mutual between clamping external member 12 and clamping ontology 11
Orthogonal position, therefore user only needs front and back push-and-pull clamping external member 12, clamps without rotating when operating this instrument
External member 12 adjusts position, to facilitate operation.
Please refer to Fig. 1 F, in another embodiment of the application, adjustable blood vessel blocking device 1 further includes push-pull rod
13, it is fixedly attached to clamping external member 12, by applying active force to pull-push piece 13, and push-pull rod 13 is made to drive clamping external member 12
Mobile relative to the clamping ontology 11, whereby, user can be by push-pull rod 13 in the external to clamping external member of patient
12 are operated.
Please refer to Figure 1A and Figure 1B, in an embodiment, clamping in the actuation part 112 of ontology 11 also has second to wear
If portion 1123, and second wears and is additionally provided with the second perforating 11231 in portion 1123, so that the push-pull rod is arranged in described second
In perforating.Push-pull rod 13 can be made to be fixed with the relative position for clamping external member 12, to facilitate through push-pull rod 13
Indirect operation clamps external member 12.
Specifically, as referring to figure 1E, push-pull rod 13 also has epitheca 131, inner core 132 and handle 133.Wherein, epitheca
131 can fix and be arranged in second perforating 11231, and export trade 131 can not carry out week relative to the second perforating 11231
To rotation, can be moved axially whereby relative to the second perforating 11231 with limiting push-pull rod 13 only.The proximal end of inner core 132
(leaning on one end of proximal operator, that is, one end far from clamping external member 12) is sheathed in epitheca 131, and inner core 132 is remote
End is then fixedly attached in clamping external member 12, so that push-pull rod 13 is fixedly connected with clamping external member 12.And then fixation connects handle 133
It is connected to the proximal end of inner core 132, and exposed (protrusion), in the surface of epitheca 131, user can be by acting on 133 application of handle
Power so that inner core 132 is moved inside epitheca 131 relative to epitheca 131, and drives clamping external member 12 relative to clamping sheet
Body 11 is mobile.
To sum up, when using the adjustable blood vessel blocking device 1 of the application, user can apply by active force first
Adjustable type blood vessel blocking device 1 is sent into patient's body by device 2, and is adjusting angle, and make to clamp ontology 11 be clamped in blood vessel or
After blood vessel and surrounding tissue, effect force applicator 2 is withdrawn from, then the grasping in vitro in patient by push-pull rod 13
Make, to adjust clamping external member 12 and clamp the relative position between ontology 11, to realize the adjusting of the arm of force.
Fig. 2A to Fig. 2 D is to show that each implementation of the second embodiment of adjustable blood vessel blocking device of the application illustrates
It is intended to.
The building block of the adjustable blood vessel blocking device 1 of the second embodiment of the application is substantially and first embodiment
