In (R1+R2) be 400~700 times of cross-sectional diameter D of flexible strap 23.The present embodiment solves the problems, such as, due to existing
Technology absolutely not provides the characteristic of strap, only records " work of rigidity satisfaction of the strap with flexibility and the strap in gravity
With the lower shape that can maintain itself substantially ", to those skilled in the art, this vague description cannot achieve, this
Field technical staff does not know the shape for how being just able to maintain strap completely.Present inventor thinks by analysis, first
Strap is needed using the flexible strap 23 for having certain stiffness and strength, secondly in view of the operability of connection, this flexibility
The diameter of strap 23 can't be too thin, and otherwise flexible strap 23 is more than certain length, and flexible strap 23 cannot maintain its shape
Shape, before installation is fixed, flexible strap 23 will be too soft and position is not capable of fixing, and cannot achieve normal conduit and fixes
Function.In addition, the size due to utensil limits, the diameter of flexible strap 23 can not be too thick, and otherwise structure can become larger, and mistake
Big rigidity causes bending angle limited, cannot firmly bind diversion pipe.Based on the above analysis, the preferably flexible strap of the present invention
23 cross-sectional diameter D is 0.1~0.5 millimeter, can be preferably made of nylon.The length of corresponding flexibility strap 23 is excellent
Choosing is no more than 50~350 millimeters.However, although the above rough reckoning is able to solve certain problem, for this field
For technical staff, for each different size of conduit retainers, it is soft with determination to require the survey calculation carried out repeatedly
The installation site of the suitable length of property strap 23, is pretty troublesome problem really.
Therefore, the proposition of the invention, for the structure type that diagram three flexible straps 23 are laid out at equal intervals, only
(R1+R2) is set as 400~700 times of the cross-sectional diameter D of flexible strap 23, for the conduit retainers of any size,
It can simply determine very much the flexible strap 23 for selecting much diameters, or select the installation site of flexible strap 23.For example,
For being specifically used for the conduit retainers of child, size cannot be too big, therefore the conduit retainers being restricted by size
When design, the range of (R1+R2) can easily be determined, and only need to select the cross section of flexible strap 23 straight at this time
Diameter D is in the range of 1/1/400th~700th (R1+R2), so that it may meet design needs, guarantee of the invention lead
Tube fixer can normal accurate fixed operation.For another example, the occasion very big for drainage pipe size, it is biggish due to needing
Fixing intensity, therefore the cross-sectional diameter D of flexible strap 23 may be determined in advance can be at this point, according to aforementioned value formula
The range that (R1+R2) is determined by 400~700 times of diameter D is also just easy to calculate further according to the range of (R1+R2)
To the parameters index of conduit retainers.
In conclusion the present invention proposes the 400 of the cross-sectional diameter D that (R1+R2) is flexible strap 23 due to creativeness
~700 times of calculation formula provides the index model of general design parameter for different applications, can be directed to
No matter different surgical environments, need the conduit retainers of which kind of size, as long as following this characteristic Design, can select well
Corresponding flexible strap is selected, is easily operated with, therefore, this design scheme of the invention has better versatility.
