Embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining The utility model, is not used to limit the utility model.

Please referring to Fig.1, Fig. 2, the embodiment of the utility model provides a kind of cerebral angiography stent, including：

Base 1；

Neck guard mechanism 2, its neck guard supporting block 21 for including being fixed on the base 1, be attached at the neck guard supporting block Neck guard supporting pad 22 in concave curved surface on 21 and two press components for being symmetrically set in 21 both ends of neck guard supporting block 23, each the press component 23 includes being vertically arranged and the lifting hydraulic cylinder of the neck guard supporting block 21 is fixed in lower end 231st, be connected with the upper end of the lifting hydraulic cylinder 231 by pressure cylinder 232 and arranged on the piston by pressure cylinder 232 Press pressure ball 233 in end；

Head protector mechanism 3, its support plate 31 for including being arranged in parallel with the neck guard supporting block 21, be connected the base 1 with The adjustment hydraulic cylinder 32 of 31 lower surface of support plate, the head protector supporting block 33 arranged on the middle part of support plate 31, be attached at institute State the head protector supporting pad 34 of the concave curved surface in head protector supporting block 33 and be symmetrically disposed on two of 31 both ends of support plate Fixation kit 35, each fixation kit 35 include lower end and are connected to fixed frame 351 in the support plate 31, for gland The geometrical clamp 352 in portion and the spring 353 of the connection geometrical clamp 352 and the fixed frame 351.

When the present embodiment cerebral angiography stent specifically acts on, head can be positioned in head protector supporting block 33, head protector branch The concave curved surface mutually agreed with human body head is provided with bracer 33, and is set in the concave curved surface of head protector supporting block 33 There is head protector supporting pad 34, which ensure that the comfort level that head is placed, when being positioned on head in head protector supporting block 33, pressable is solid Determine the geometrical clamp 352 of component 35 so that the spring 353 of two fixation kits 35 compresses, after head is positioned in supporting block, Geometrical clamp 352, which is pushed against, under the action of spring 353 fixes head in human body head, due to use spring 353, therefore its fix support Surging will not be excessive, it advantageously ensures that the fixation comfort on head；When being positioned on head in head protector supporting block 33, human body Neck is corresponded to and is positioned in neck guard supporting block 21, when the height of neck guard supporting block 21 and head protector supporting block 33 is not suitable for, can be led to Cross adjustment hydraulic cylinder 32 and adjust the height of support plate 31, and then adjust the relatively high of head protector supporting block 33 and neck guard supporting block 21 Degree, ensures the comfort level that neck guard supporting block 21 and head protector supporting block 33 respectively support neck and head.It is corresponding, the present embodiment The concave curved surface mutually agreed with neck, and corresponding setting neck guard supporting pad 22 are also equipped with neck guard supporting block 21, The internal carotid of neck both sides can be pressed respectively by two press components 23 at the same time, and then improve the development effect of internal carotid Fruit, specifically, two press components 23 of the present embodiment can adjust height in vertical direction by lifting hydraulic cylinder 231, and leads to The dynamics by the adjustment pressing of pressure cylinder 232 is crossed, it advantageously ensures that the pressing accuracy and adjustability of different crowd, and adopts With in the spherical comfort for being pressed by pressure ball 233, ensure that pressing.

And in order to ensure comfort that head is clamped, the opposite side of the geometrical clamp 352 of the present embodiment two is respectively provided with For concave curved surface, and gripper pad 354 is both provided with the concave curved surface of the geometrical clamp 352, and geometrical clamp 352 is interior Concave arc surface can be set mutually to be agreed with human body head both sides, ensures the comfort level gripped.

Since the difference of human body head size is larger, in order to improve the adaptability of the present embodiment cerebral angiography stent, this reality Apply example 31 upper surface of support plate and be provided with two guide grooves 311 arranged along its length, two guide grooves 311 are symmetrical 33 both sides of head protector supporting block are arranged at, the fixation kit 35 further includes one end and is connected, separately with the head protector supporting block 33 One end drives the clamping hydraulic cylinder 355 that the fixed frame 351 is moved along the guide groove 311, is supported when being positioned over head in head protector When on block 33, by clamping hydraulic cylinder 355 two fixed frames 351 can be driven remote, that is, drive two geometrical clamps 352 remote, when After head is positioned in head protector supporting block 33, by clamping hydraulic cylinder 355 two geometrical clamps 352 can be driven close by human body head Grip.

For the ease of driving fixed frame 351, guide groove 311 described in the present embodiment is less than its groove for dovetail groove and its width of rebate Bottom width degree, 351 lower end of fixed frame, which coordinates, to be embedded in the guide groove 311,351 lower end of fixed frame can be specifically arranged to 311 phase of guide groove is agreed with trapezoidal.

Compared with prior art, on the one hand the utility model sets neck guard mechanism 2, it supports neck by neck guard supporting block 21 Portion, improves the comfort level of neck in angiographic procedure, and can coordinate pressing internal carotid by press component 23, avoids to be formed The x-ray of radiography precision is influenced, on the other hand head protector mechanism 3 is set, it can pass through head protector supporting block 33 and two fixation kits Head is fixed in 35 cooperation, and fixation kit 35 is supported, is buffered using spring 353, it, which is conducive to improve, fixes Stability and comfort.
