Abstract

The invention provides a novel viewSite brain access system (VBAS). The VBAS comprises a tubular main body which is made of a transparent material, has elliptical section and has slight taper in the axial direction, wherein an edge is arranged at the upper end of the tubular main body; and a connection handle is arranged on the margin of the edge. The VBAS is characterized in that a matched expansion tube is arranged on the inner side of the lower end of the tubular main body; a lower sealing ring which is elastically locked outside the expansion tube is arranged at the lower end of the tubular main body; an upper sealing ring which is elastically tensioned on the inner side of the tubular main body is arranged at the upper end of the expansion tube; and a circular and smooth bottom necking is arranged at the bottom of the expansion tube. The VBAS has the following advantages: the height of the tubular main body and the aperture of the bottom necking can be adjusted as required, thus the production and operation costs are greatly lowered; and the VBAS is unnecessary to replace during operation, thus avoiding causing extra harms to patients.

Thebottom constriction 4 in this embodiment is a fixed structure, and its diameter is fixed.

图1中的伸缩管3缩入管状主体2内，在需要延长时，可以根据需要向下拉出伸缩管3局部或全部，图2所示是伸缩管3全部伸出的状态。Thetelescopic tube 3 in Fig. 1 is retracted into the tubularmain body 2, and when it needs to be extended, part or all of thetelescopic tube 3 can be pulled out downwards as required, and Fig. 2 shows the state where thetelescopic tube 3 is fully stretched out.

参见图4-图13，该实施例是所述的底部缩口4为可改变口径的结构，底部缩口4为花瓣形结构，在多个花瓣41的根部的内侧和外侧均设有沿圆周的内侧的凹槽8和外侧的凹槽9，其作用是使得花瓣41容易在此处弯曲。在该底部缩口的花瓣41外侧设有弹性膜42，在没有外力的情况下，弹性膜42将多个花瓣41聚拢在一起（各个花瓣41之间没有间隙，参见图4-图6），此时的口径最小；在需要扩大口径时，用一个合适口径的扩大环7（参见图12和图13）从底部缩口4的内部向下卡入口径内，使得口径边缘卡入扩大环7外沿的卡槽71内，此时的底部缩口4的口径被扩大，各个花瓣41之间出现尖角形的间隙，但外侧还有弹性膜42包覆（参见图8-图11）。弹性膜42可采用医用硅胶。Referring to Fig. 4-Fig. 13, in this embodiment, thebottom constriction 4 is a structure that can change the caliber, thebottom constriction 4 is a petal-shaped structure, and the inner and outer sides of the root of a plurality ofpetals 41 are provided with a ring along the circumference. The inner groove 8 and the outer groove 9 are used to make thepetal 41 easy to bend here. Anelastic film 42 is provided on the outside of thepetals 41 constricted at the bottom. In the absence of external force, theelastic film 42 gathers thepetals 41 together (there is no gap between thepetals 41, see Fig. 4-Fig. 6), At this time, the caliber is the smallest; when the caliber needs to be enlarged, use anexpansion ring 7 of a suitable caliber (see Figure 12 and Figure 13) to snap into the diameter from the inside of thebottom constriction 4, so that the edge of the caliber snaps into theexpansion ring 7 In theslot 71 on the outer edge, the diameter of thebottom constriction 4 is enlarged at this time, and there are pointed gaps between thepetals 41, but the outer side is covered by the elastic membrane 42 (see Fig. 8-Fig. 11).Elastic film 42 can adopt medical silica gel.

本发明的第三实施例是上面两个实施例相互结合（未图示），即将第一实施例中的底部缩口4改为第二实施例中的花瓣形结构，其他不变。具有可以伸长高度和扩大底部缩口4口径的两个功能。The third embodiment of the present invention is the combination of the above two embodiments (not shown), that is, thebottom constriction 4 in the first embodiment is changed to the petal-shaped structure in the second embodiment, and the others remain unchanged. It has two functions of extending the height and enlarging thebottom neck 4 caliber.
