Detailed Description

The invention provides a disposable circumcision anastomat, which realizes the drainage effect on lymph fluid by improving the structural design of the inner side edge of a blunt incision, effectively prevents edema and can accelerate the healing of a foreskin wound.

Referring to fig. 1 and 2, the disposable circumcision anastomat according to the embodiment of the invention comprises an outer ring 1 and an inner ring 2 which are matched with each other, wherein a blunt knife edge 11 for extruding foreskin is arranged on the inner side of the outer ring 1, the blunt knife edge 11 is in a sheet shape, and the blunt knife edge 11 forms a ring shape after the outer ring 1 is closed. The thickness of the blunt edge 11 is gradually reduced from outside to inside, thereby forming an edge part 12 on the inner side. A plurality of concave pits 13 (for example, ten concave pits are uniformly distributed, and the design can be adjusted according to the requirement) are arranged on a circle of annular surface of the inner side edge part 12 of the blunt edge. The recesses 13 are preferably circular, point-like recesses as shown in fig. 1 or vertical, linear, longitudinal, strip-like grooves as shown in fig. 4, the depth of the recesses 13 preferably being 2mm, which, whatever the shape used, occupy only a small part of the edge and do not affect the integrity of the edge. . In the prior art, the blunt incision 11 does not have the concave pit 13, so the foreskin in the structures of the outer ring 1 and the inner ring 2 is in a fully closed state, and edema is easily caused.

The inner ring 2 is, for example, ring-shaped and has an upper flange 24 and a lower flange 26 protruding outward at both ends, and the foreskin is clamped and fixed between the inner ring side wall 25 and the blunt incision 11 between the two flanges, which is more stable. Preferably, the inner ring 2 is provided with a plurality of convex points 21 on the outer side, and the convex points 21 correspond to the concave pits 13 one by one, so that when in use, the convex points 21 enter the concave pits 13 to penetrate the foreskin inner plate and the foreskin outer plate, so that lymph fluid between the foreskin inner plate and the foreskin outer plate seeps out, and further the accumulation of the lymph fluid is prevented. At the position of the blunt knife edge 11 without the convex points 13, a certain distance is reserved between the blade part 12 and the inner ring 2, and a gap for accommodating the foreskin is formed.

Referring to fig. 3, in some embodiments, the inner ring 2 further includes an elastic washer 22 disposed at an outer side thereof (the elastic washer 22 and the inner ring 2 may be a split structure or an integrated structure), for example, made of a rubber material, so as to have a larger friction force and a better stabilizing effect, the elastic washer 22 is provided with a washer recess 23 at a position corresponding to the recess 13, and the washer recess 23 is preferably a through hole connected to the recess 13.

Further preferably, an indicator is provided on the outer ring and/or the inner ring at a position corresponding to the pit. As shown in fig. 1, an outer ring indicator 14 is provided on the outer ring 1 at a position corresponding to the dimples 13; as shown in fig. 5, inner ring indicators 28 are provided on the inner ring 2 at positions corresponding to the dimples 13 (or the bumps 21). Preferably, the outer ring 1 and the inner ring 2 are provided with indicator structures. For the outer ring 1, the outer ring indicator 14 may be arranged on the upper surface of the outer cylinder, the outer side surface and/or the upper surface of the blunt edge 11, etc.; for the inner ring 2, the pit indicator 28 may be provided on the upper surface and/or the outer side surface of the upper flange 24, or the like. The outer ring indicator 14 and the inner ring indicator 28 may be any type of indicia, such as in relief as protrusions, grooves, or simply in the form of lines drawn on a surface. The outer ring indicator 14 and the inner ring indicator 28 serve to facilitate viewing and alignment during installation.

Referring to fig. 2, at least one circle of blunt knife edges 11 are arranged on the inner side of the outer ring 1, and the upper and lower sides of the blunt knife edges 11 are preferably frosted surfaces, so as to prevent adhesion. The blunt knife edge 11 is provided with an upper half knife edge extension part 15A and a lower half knife edge extension part 15B which are matched with each other at two ends of the opening of the outer ring 1 (and at movably connected positions in a two-section or multi-section structure), for example, the thickness of the corresponding position is reduced by half, the upper half knife edge extension part 15A is only reserved on the upper half part, the lower half knife edge extension part 15B is only reserved on the lower half part, and the upper half knife edge extension part and the lower half knife edge extension part can be overlapped together in the closing process of the outer ring 1. The outer ends of the upper and lower

knife edge extensions

15A, 15B have rounded corners 16 so that the inner edges are smoothly curved when opening and closing and do not erroneously clamp the foreskin during closing.

The two ends of the outer ring 1 are respectively provided with a first combining block 17A and a second combining block 17B, the two combining blocks are arranged at a high position and a low position, the opposite surfaces are provided with saw teeth, the slope of the saw teeth at the opposite side of the opening of the outer ring 1 is relatively slow, and the slope of the saw teeth at the outward side is relatively steep, so that the opening can be clamped and fixed when being closed, and the saw teeth cannot be easily separated (after the disposable circumcision anastomat is used, the first combining block 17A and the second combining block 17B can be pried by a hard rod tool). Preferably, at least one of the first and

second coupling blocks

17A and 17B is provided with an elastic groove 18, and the thickness of the portion of the outer ring 1 to which the first and/or

second coupling blocks

17A and 17B are connected is reduced by the elastic groove 18, so that the elastic deformation is more easily generated, and the outer ring 1 can be more easily engaged when being mounted and closed. In addition, in order to make the clamping and fixing effect better, it is preferable to arrange the first and second coupling blocks and the upper and lower half blade extensions in a staggered manner, that is, for example, as shown in fig. 1, the first coupling block 17A is located below, the upper half blade extension 15A is adjacent to the first coupling block 17A, and the other end of the coupling is located above the second coupling block 17B and the lower half blade extension 15B, so that after the outer ring 1 is closed, the upper half blade extension 15A and the lower half blade extension 15B can simultaneously play a role of limiting the first coupling block 17A and the second coupling block 17B, and prevent the first coupling block 17A and the second coupling block 17B from slipping and separating. It should be noted that other fastening structures or bolt and screw hole structures that can perform similar fixing functions may be used, and the invention is not limited thereto.

In still other embodiments of the present invention, referring to fig. 5 and 6, at least two circles of blunt incision (e.g. including an upper incision 11A and a lower incision 11B) are disposed inside the outer ring 1 to form a double-incision (or multi-incision) structure, so as to enhance the blocking effect on the foreskin, and a certain volume of space is naturally formed between two or more incisions, so that absorbent cotton, ointment or liquid medicine can be placed between the two or more incisions, thereby eliminating inflammation and accelerating healing. Alternatively, the upper blade 11A and the lower blade 11B (or more blades) may be provided with the dimples in only one circle or both with the dimples 13, and the dimples 13 on the upper blade 11A and the lower blade 11B (or more blades) may be aligned up and down or staggered up and down. And, the inner ring 2 can be selected to have the salient point 21 of upper and lower two rows (or more rows) of corresponding to offer, the inner ring 2 is equipped with the middle part and raised 27 in the position between two rows or multirow knife edges correspondingly, form the trough corresponding to double knife edge (or more knife edges) with the upper flange 24 and lower flange 26, further strengthen the clamping and blocking effect to treat removing the foreskin, make its blood flow not smooth but necrotic.

As shown in fig. 7, the outer ring 1 may be an integral C-shaped structure made of a soft material (e.g., soft plastic) and opened and closed by its flexibility; or as shown in fig. 2 and fig. 1, the two or three sections and the multi-section structure are movably connected, each section is arc-shaped, and the sections are rotatably connected through a pivot structure so as to realize opening and closing.

On the other hand, the inner ring 2 can adopt a whole annular structure as shown in fig. 1, and can also adopt a two-section (or multi-section) arc-shaped structure as shown in fig. 6, so that the discomfort of a patient caused by the fixed inner diameter of the inner ring 2 is avoided, and the installation and the removal are more convenient.

As shown in fig. 4, the disposable circumcision anastomat of the invention can be circular or elliptical, and the shapes of the outer ring 1 and the inner ring 2 are matched.

In conclusion, the disposable circumcision anastomat at least has the following beneficial effects:

the disposable circumcision anastomat is provided with the concave pit 13 at the inner side of the blunt incision 11 of the outer ring 1, plays a role in draining lymph fluid, effectively prevents edema and can accelerate the healing of a foreskin wound.
