Be provided with groove along its length, second point of cutting ring 6 be provided with close to the side of first point of cutting ring 5 be used cooperatively it is convex
Edge.Alternatively, first point of cutting ring 5 is provided with convex edge along its length, second point of cutting close to the side of second point of cutting ring 6
Ring 6 is provided with the groove being used cooperatively close to the side of first point of cutting ring 5.Matched by the way that the sliding being arranged along its length is arranged
Close the groove that uses and convex edge so that form the cutting ring first point of cutting ring 5 and second point of cutting ring 6 it is effective
Connection length is able to carry out adjustment.The sliding relative movement of first point of cutting ring 5 and second point of cutting ring 6 for convenience, first
Divide cutting ring 5 and second point of cutting ring 6 is arc-shaped, the radius of the arc-shaped is the length of corresponding cutting arm 2, and the center of circle is
The intersection point of cutting arm 2 and guide rod 1, so that the opposite sliding of first point of cutting ring 5 and second point of cutting ring 6 is more smooth.
Wherein, the cross section of the groove is T shape, arc-shaped or swallow-tail form, is also possible to other skilled in the art
Common shape, such as U-shaped.The cross sectional shape of the convex edge is corresponding with the cross sectional shape of the groove.
In another embodiment, as shown in Figure 1 to Figure 3, the position that first point of cutting ring 5 is connect with second point of cutting ring 6
For hollow cylinder-like structure 51, second point of cutting ring 6 is slidably connected at the interior of the cylinder-like structure 51 of first point of cutting ring 5
Portion.Alternatively, the position that second point of cutting ring 6 is connect with first point of cutting ring 5 is hollow cylinder-like structure 51, first point of cutting
Ring 5 is slidably connected at the inside of the cylinder-like structure 51 of second point of cutting ring 6.First point of cutting ring 5 and second point for convenience
The sliding relative movement of cutting ring 6, first point of cutting ring 5 and second point of cutting ring 6 are arc-shaped, the radius of the arc-shaped with
Above-described embodiment is identical, and the radius of the arc-shaped is the length of corresponding cutting arm 2, and the center of circle is corresponding cutting arm 2 and lead
The intersection point of bar 1.
In another embodiment, as shown in Figure 4 and Figure 5, it further includes capableing of conductive connection sleeve 4 that cutting, which is fastened with a rope, string, etc., and first point
Cutting ring 5 and second point of cutting ring 6 one end close to each other are slidably connected in connection sleeve 4.First point of electricity for convenience
The sliding relative movement of ring 5 and second point of cutting ring 6 is cut, first point of cutting ring, 5, second points of cutting rings 6 and connection sleeve 4 are
The radius of arc-shaped, the arc-shaped is same as the previously described embodiments.
Wherein, in order to prevent in sliding process, first point of cutting ring 5 or second point of cutting ring 6 take off out of connection sleeve 4
Out, the diameter for connecting the both ends open position of sleeve 4 is less than the intracavity diameter of connection sleeve 4, first point of cutting ring 5 and second point
The diameter dimension of cutting ring 6 is corresponding with the connection diameter of aperture position of sleeve 4, first point of cutting ring 5 and second point of cutting ring 6
End diameter in connection sleeve 4 is corresponding with the connection intracavity diameter of sleeve 4, to effectively prevent first point of cutting ring 5
Or second point of cutting ring 6 is located at the end abjection in connection sleeve 4.
Specifically, end of the cutting arm 2 far from guide rod 1 is arranged in the cutting ring.
As shown in Figure 9 and Figure 10, cutting button loop provided by the invention, in single cut, cutting button loop stretches out the behaviour of resectoscope
Make cavity, since the resilient support of the spring 3 on cutting button loop makes to cut off every time so that the cutting amplitude of cutting button loop obviously expands
The width of tissue obviously increases, and the tissue block cut every time is significantly greater than the immutable tissue block for cutting the button loop excision of width cutting, excision
The speed of tissue will be greatly speeded up, so that operative speed is obviously accelerated, improve the speed of operation, reduce going out for the surface of a wound
Blood improves the safety of operation.After cutting, cutting button loop retracts the operation cavity of resectoscope, at this point, two cutting arms 2 are pressed
It closes, angle becomes smaller, and spring 3 is compressed.The length of the operation cavity of resectoscope, control cutting button loop are stretched out by control cutting arm 2
Effective cutting width, i.e., by resectoscope operation cavity cavity wall suppress cutting arm 2 different location, to realize to spring
The adjustment of 3 reduction length, to control effective cutting width of cutting button loop.
The cutting of the various embodiments described above is fastened with a rope, string, etc., and can be not only used cooperatively with transurethral prostate resection mirror, can also change cutting
In the case where the size of button loop, for being used cooperatively with ureteroscope and kidney mirror, in use, cutting button loop passes through the behaviour of these endoscopes
Make channel merging, enters and carry out tissue cutting actions in ureteral lumen or kidney aggregation system.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
