Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings.It is retouched in of the invention
In stating, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", " length ", " width ", " thickness ", "upper", "lower",
"front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside", " clockwise ", " counterclockwise ", " axis
To ", " radial direction ", the orientation or positional relationship of the instructions such as " circumferential direction " be to be based on the orientation or positional relationship shown in the drawings.
In addition, term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance
Or implicitly indicate the quantity of indicated technical characteristic.Define " first " as a result, the feature of " second " can be expressed or
Implicitly include at least one this feature.In the description of the present invention, the meaning of " plurality " is at least two, such as two, three
It is a etc., unless otherwise specifically defined.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to for solving
The present invention is released, and is not considered as limiting the invention.
As shown in Figure 1 to Figure 3, blood vessel clip of the invention includes the first clamp arm 1 and the second clamp arm 2.
As shown in Figure 1, the first clamp arm 1 includes the first bar 101 and the second bar 102, the first bar 101 hangs down with 102 phase of the second bar
Directly at T-shaped.The length of first bar 101 is greater than the length of the second bar 102.First bar 101 includes first end and second end, the
One end is the insertion end matched with the first element 201 of the second clamp arm 2, the first bar 101 and the second phase at second end of bar 102
Connection is integrally formed.
As shown in Fig. 2, the second clamp arm 2 includes first element 201, second element 202 and intermediary element 203.First element
201 be in the first arc, is connected or is integrally formed with intermediary element 203, also, intermediary element 203 is located at the first arc
Inside.First element 201 includes the first sheet shaped piece 2011 and the second sheet shaped piece 2022, the top and second of the first sheet shaped piece 2011
There is gap between the top of sheet shaped piece 2022, the middle part of the middle part of the first sheet shaped piece 2011 and the second sheet shaped piece 2022 it
Between formed hole 2013, the lower part of the first sheet shaped piece 2011 and the lower part of the second sheet shaped piece 2022 are integrated.Gap and hole 2013 connect
It is logical.Due to the presence in gap, when the first end of the first bar 101 of the first clamp arm 1 is pressed into, with first end against first
The top of shape part 2011 and the top of the second sheet shaped piece 2022 are easier to that flexible deformation occurs, so that the first end of the first bar 101
It is easy to slide and be pressed into.Hole 2013 is used to accommodate the first end of the first bar 101 of the first clamp arm 1 being pressed into and stops to it
Dynamic, after first end access aperture 2013, the first clamp arm 1 fits closely the engaging, it can be achieved that blood vessel clip with the second clamp arm 2, in turn
Realize clamping, the hemostasis to blood vessel.The shape of the first end of first bar 101 of the shape in hole 2013 and the first clamp arm 1 is adapted.
For arc, the present invention defines the inside that center of circle side is arc, and the other side of arc is outside, that is, arc is
Indent evagination."upper", "lower" direction are based on orientation and positional relationship shown in Fig. 2.
As shown in Fig. 2, second element 202 includes the lower part and arc-shaped top in plane.The lower part of second element 202
For plane, can fit with the lower surface of the second bar 102 after blood vessel clip engaging.The top of second element 202 is in the second arc,
The arc length of second arc is greater than the first arc.Longer second arc of arc length makes the intensity with higher of second element 202.The
The top of two element 202 has through slot 2021, and at least part on the top of second element 202 is separated into two by through slot 2021
Small arc-shaped workpiece.Obviously, the distance that through slot 2021 is extended on the top of second element 202 is longer, the first clamp arm 1 and the second clamp arm
Maximum opening angle between 2 is bigger.Through slot 2021 to open between the first clamp arm 1 and the second clamp arm 2 with wide-angle, just
In clamping blood vessel.The lower part of second element 202 is connected or is integrally formed with intermediary element 203, also, intermediary element 203
In the inside of the second arc.
Intermediary element 203 is linear, is preferably straight-bar.
In the space that the second element 202 that second bar 102 of the first clamp arm 1 is placed in the second clamp arm 2 is surrounded.When opening,
The part of the second end of first bar 101 of the first clamp arm 1 or neighbouring second end is located in through slot 2021.First clamp arm 1 is pushed,
With its rotation, the first end of the first bar 101 and the first sheet shaped piece 2011 of first element 201 and the second sheet shaped piece 2022 are slided
Contact, and make the first sheet shaped piece 2011 and the second sheet shaped piece 2022 that elastic deformation occur.The first end of first bar 101 continues to turn
Dynamic, in access aperture 2013, the first sheet shaped piece 2011 and the second sheet shaped piece 2022 restore from elastic deformation, the first clamp arm 1 with
Second clamp arm 2 fits closely, and realizes the engaging of blood vessel clip, and then realizes clamping, the hemostasis to blood vessel.Also, with the first folder
The rotation of arm 1, even if the first end in the first bar 101 of the first clamp arm 1 is housed inside the first element 201 of the second clamp arm 2
After in hole 2013, the arc length of the second arc still makes the second end of the first bar 101 of the first clamp arm 1 or the part of neighbouring second end
Without being detached from from through slot 2021 in through slot 2021.
