So, the stability coordinating between the preparation for ease of body 1 and mounting ring 21 and body 1, above-mentioned raised 14 are preferably annular
Raised.
Mode two, as shown in Figure 3 b, the side wall of body 1 is provided with annular groove 16 corresponding with mounting ring 21, mounting ring 21
It is limited in the annular groove 16 of body 1.
Mode three, as shown in Figure 3 c, is connected by multiple rivets 4 between mounting ring 21 and body 1, specifically, on body 1
It is provided with the stopper slot 15 of the annular towards mounting ring 21 for the opening, mounting ring 21 is provided with multiple through holes running through its thickness direction,
It is provided with one to slotting rivet 4 in each through hole；Wherein, each includes two band cap bodies of rod to slotting rivet 4, as institute in Fig. 3 c
The band cap body of rod 41 showing and the band cap body of rod 42, are mutually inserted with the body of rod with the cap body of rod 42 with the cap body of rod 41 and the body of rod, and carry cap
The cap body of the body of rod 42 is limited in stopper slot 15 and is slidably matched with stopper slot 15, and the body of rod runs through the through hole of mounting ring 21；Band cap
The one side that the cap body of the body of rod 41 deviates from body 1 with mounting ring 21 offsets, to realize the activity between mounting ring 21 and body 1 even
Connect.
Certainly, can also be connected by other means between the mounting ring 21 of handle 2 and body 1, no longer go to live in the household of one's in-laws on getting married one by one here
State.
Further, in order to reduce the body 1 of anus-expanding unit in operation the damage to tissue it is preferable that on
State the fillet between the side wall of the perisporium of positioning port 11 and body 1 in the body 1 of anus-expanding unit with smooth excessiveness.Positioning port 11
Perisporium and body 1 side wall between there is the fillet seamlessly transitting, can prevent the body 1 of anus-expanding unit stretch into anus and adjust
During whole positioning port 11 position location, belong between the perisporium of positioning port 11 and tissue and seamlessly transit, and then reduce
The damage to tissue for the perisporium of positioning port 11.
In a kind of preferred implementation, in order that body 1 can stretch into different length, handle 2 edge according to actual needs
Axial line 3 direction of body 1 is adjustably installed on the side wall of body 1.By installation position on body 1 side wall for the regulation handle 2
Put, the distance between mounting ring and body top can be adjusted, realize body 1 is stretched into the adjustment of anus depth.
In a kind of preferred implementation, the mounting ring 21 of handle 2 is flexible installing ring, has certain elasticity, mounting ring
That passes through mounting ring 21 between 21 and body 1 tightens up power cooperation, when needing to adjust installation site on body 1 for the handle 2, directly
Axial line 3 direction along body 1 promotes mounting ring 21.Certainly, mounting ring 21 can also by two can snapping hemizonid
Formed, enclosed ring handle 2 being arranged on body 1 after two hemizonid snappings, can be formed, need along body 1
During the installation site of axial line 3 direction regulation handle 2, two hemizonids are taken apart, determine after good position again by two hemizonids
Snapping, and then handle 2 is arranged in defined location.
On the basis of the respective embodiments described above, refer to Fig. 2, in a kind of preferred implementation, along the axial line of body 1
3 directions, the side wall of body 1 has multiple scale mechanisms 12 being arranged in order.Operative doctor is according to the scale on body 1 side wall
Mechanism 12 can intuitively obtain the length that body 1 stretches into anus, and then judges surgery location；Operative doctor can also be according to this
Scale mechanism 12 on body 1 makes the body 1 of anus-expanding unit stretch into suitable depth, thus preferably being performed the operation.
Preferably, said scale mechanism 12 is the scale groove being engraved on body 1 side wall or is printed on body 1 side wall
Scale.
In addition, judge the position of anal pathological tissues according to scale for the ease of operative doctor, as shown in Fig. 2 it is engraved in
Scale groove on body 1 side wall or the expression word being printed in the scale on body 1 side wall are seen as reversely outside body 1
Word, i.e. the word seen during scale on body 1 internal read body 1 in operative doctor operation process is positive word,
It is easy to read.
It is highly preferred that the spacing between the two of arbitrary neighborhood scale grooves is equal.
Obviously, those skilled in the art can carry out various changes and modification without deviating from this to the embodiment of the present invention
Bright spirit and scope.So, if these modifications of the present invention and modification belong to the claims in the present invention and its equivalent technologies
Within the scope of, then the present invention is also intended to comprise these changes and modification.
