DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(17) Referring to FIGS. 1-3 of the drawings, a disposable circumcision anastomat is illustrated, comprising: an inner ring 2 and an outer ring 1 corresponding to the inner ring 2; wherein a corresponding closure structure 4 is provided at an outer ring opening, which overlaps for forming a smooth closure. The disposable circumcision anastomat may further comprise an elastic gasket between the inner ring 2 and the outer ring 1.

(18) Referring to FIG. 5, the outer ring 1 is formed by three arc structures hinged to each other (comprising two first arc structures 3 and a second arc structure 5). Besides, the outer ring 1 may be formed by two first arc structures 3, two first arc structures 3 and two second arc structures 5, or two first arc structures 3 and more second arc structures 5.

(19) Referring to FIG. 6, the arc structures comprises arc sidewalls, and the arc sidewalls are connected to arc blades 7; a loop blade is formed by a plurality of the arc blades 7 with cutting edges facing inwards (as shown in FIG. 5); convex structures 8 are arranged on the arc sidewalls.

(20) When the elastic gasket is not used by the disposable circumcision anastomat, a width S1 of each of the convex structures 8 is no wider than a width S2 of any of the arc blades 7, because if not, no sufficient cutting engagement can be provided. According to clinical researches, in practice of cutting prepuce tissues, when the width of the convex structures 8 equals to the width the arc blades 7, sufficient cutting engagement is also provided (as shown in FIG. 14).

(21) When the elastic gasket is used by the disposable circumcision anastomat, a width of each of the convex structures 8 is no wider than a combination of a width of any of the arc blades 7 and a thickness of the elastic gasket, and is no narrower than a difference of the width of any of the arc blades 7 and the thickness of the elastic gasket. That is to say, S2DS1S2+D. If S1<S2D, when the arc blades 7 contact with the elastic gasket after cutting the prepuce, the convex structures 8 are still not able to touch the elastic gasket, resulting in no effect. If S1>S2+D, when the convex structures 8 presses into the elastic gasket and presses against the inner ring 2, the arc blades 7 are still not able to closely contact with the elastic gasket and the prepuce tissues, which means no sufficient cutting engagement.

(22) Referring to FIG. 4, the convex structures 8 are repeatedly arranged on the arc sidewalls and extend towards a loop center.

(23) When removing redundant prepuce or phimosis with the disposable circumcision anastomat, the inner ring 2 (if there is the elastic gasket, then the elastic gasket is sleeved outside the inner ring 2) is placed between a prepuce inner plate and a glans and adjusted. The outer ring 1 is placed at a position corresponding to the inner ring 2 and outer than a prepuce outer plate. The prepuce is adjusted to a proper position before tightening the corresponding closure structure 4. The redundant prepuce is cut with a blade along the loop blade. With the disposable circumcision anastomat for removing redundant prepuce or phimosis, incision is neat, postoperative bleeding hardly happens, operation is easy, and operation time is short. After removing the circumcision device, a prepuce surgery section is difficult to bleed, wound is smooth, and physical as well as mental health of the patient receives good care.

(24) The convex structures 8 on the arc blades 7 are jagged, triangular, spike or conical. On one hand, the convex structures 8 provide a sufficient fixing effect, so as to enable tight fixing and sufficient jointing between the inner and outer prepuce plates, and avoid sliding or even falling off and bleeding. On the other hand, intervals between the convex structures 8 enable smooth blood flow when fixing tissues, avoiding tissue necrosis.

(25) The convex structures 8 on the arc blades 7 are repeatedly arranged with an interval of 1.0-10.0 mm, so as to ensure sufficient fixing, for avoiding avascular necrosis at a far side of the fixed tissue or hidden dangers such as prepuce cracking and bleeding due to unstable fixing and easy falling off, thus providing a relative aesthetic surgical result.

(26) The arc blades 7 have effects such as cutting, fitting, and preventing bacterial infection. During operation, the convex structures 8 fix the tissues, and the arc blades 7 cooperate with the inner ring 2 and the outer elastic gasket for cutting the prepuce tissues. Meanwhile, cutting wounds of the inner and outer prepuce plates are neatly engaged for achieving engagement. After cutting, the arc blades 7 and the external sidewalls of the inner ring 2 form a relatively sealed face (when using the elastic gasket, the arc blades 7 may form the relatively sealed face with the elastic gasket and the external sidewalls of the inner ring 2), wherein the relatively sealed face provides better protection to the cutting wounds of the prepuce, and prevents bacterial infection.

(27) Referring to FIG. 6, the convex structures 8 may be placed at any position on the arc sidewalls, and there are certain intervals between the arc blades 7 and the convex structures 8, so as to form containing spaces 6 therebetween. If the containing spaces 6 formed by the arc blades 7 and the convex structures 8 are smooth arc as shown in FIG. 8, then smooth transition is provided to the inner and outer prepuce plates, which promotes wound healing and further improves the aesthetic surgical result.

(28) Parallel distances between the arc blades 7 and the convex structures 8 may be 1.5-6.0 mm, in such a manner that tissue binding is extremely tight, no falling off happens, and postoperative prepuce length is proper. Fixed prepuce tissue falling off, bleeding or improper postoperative prepuce length is avoided as much as possible, so as to achieve a desired outcome.

(29) Referring to FIG. 8, first ends of the first arc structures 3 have arc transition structures 12, and second ends of the first arc structures 3 have the corresponding closure structure 4. Referring to FIGS. 9 and 10, both a first end and a second end of the second arc structure 5 have the arc transition structures 12, wherein the arc transition structures 12 at the first end of the second arc structure 5 are placed at top faces of the arc blades 7, and the arc transition structures 12 at the second end of the second arc structure 5 are placed at lower faces of the arc blades 7. The arc transition structures 12 enable smooth closure of edges of the arc blades 7, so as to prevent the prepuce tissues from being clutched in a joint portion of the loop blade.

(30) Referring to FIG. 11, upper edges of external sidewalls of the inner ring 2 have loop convexes 9, and lower edges of the external sidewalls of the inner ring 2 have intermittent convexes 10. Referring to FIG. 12, both the upper and lower edges have the intermittent convexes 10. Alternatively, both the upper and lower edges may have the loop convexes 9.

(31) Referring to FIG. 13, the outer ring 1 has at least two through-holes 11, and the through-holes 11 are placed between the arc blades 7 and the convex structures 8. The through-holes 11 may be arranged on a same arc structure or on different arc structures. The through-holes 11 are suitable for injection.

(32) The disposable circumcision anastomat with the through-holes 11 further comprises a fixing fiber, wherein the fixing fiber passes through one of the through-holes 11 and bypasses the inner ring 2, then passes through the other of the through-holes 11. During operation, the inner ring 2 is placed between a prepuce inner plate and a glans and adjusted. The outer ring 1 is placed at a position corresponding to the inner ring 2 and outer than a prepuce outer plate. The prepuce is adjusted to a proper position before fixing the inner and outer prepuce plates on the inner ring 2 with the fixing fiber and closing the outer ring 1. After reaching a desired result, the fixing fiber is removed, and the redundant prepuce is cut with a blade along the loop blade. With the fixing fiber, the inner and outer prepuce plates are fixed on the inner ring 2 in a better condition for adjusting a prepuce cutting range. Meanwhile, the prepuce is fixed more smoothly between the inner ring 2 and the outer ring 1 for avoiding folding.

(33) It is known to persons skilled in the art that the closure structure 4 may be a corresponding screw hole structure, wherein a screw bolt passes through the screw hole for closing. The closure structure 4 may also be a corresponding Z-shaped structure as shown in FIG. 1, which uses a clutching effect of the Z-shaped structure for fixing. Besides, the closure structure 4 may adopt an opening plug structure, a fiber tying structure or other structures for fixing.

(34) It will thus be seen that the objects of the present invention have been fully and effectively accomplished. Its embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
