[0031] The present invention will be described below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figures 1 to 5 As shown, a novel foreskin dilator comprises a base member 1 and a foreskin dilator 2 , wherein the foreskin dilator 2 is provided with at least two elastic dilating arms 21 .

[0033] Further, such as Figures 1 to 5 As shown, the base member 1 includes a first base portion 11 , and an abutment top portion 12 is respectively provided at the edge portion of the first base portion 11 corresponding to each elastic expansion arm 21 . The first base portion 11 and the abutment top portion 12 are an integral structure, and a first through hole 13 is opened at the center position of the first base portion 11 .

[0034] Furthermore, Figures 1 to 5 As shown, the foreskin expander 2 includes a second base 22 , and each elastic expansion arm 21 is respectively arranged at the edge of the second base 22 . The second base 22 and the elastic expansion arm 21 are an integral structure, and a second through hole 23 is opened at the center of the second base 22 .

[0035] Also, if Figures 1 to 5 As shown, the novel foreskin dilator also includes an adjusting bolt 3 and an adjusting nut 4. The adjusting bolt 3 includes a large head end 31 and a threaded rod 32. The threaded rod 32 of the adjusting bolt 3 passes through the second through hole 23 and the first through hole 13 from front to back in sequence. The adjusting nut 4 is screwed to the threaded rod 32 of the adjusting bolt 3. The first base 11 and the second base 22 are located between the large head end 31 of the adjusting bolt 3 and the adjusting nut 4.

[0036] In addition, if Figures 1 to 5 As shown, the front end of each elastic expansion arm 21 extends to the front side of the corresponding abutment portion 12 , and each abutment portion 12 contacts and presses the rear end of the corresponding elastic expansion arm 21 .

[0037] It should be pointed out that the base component 1 and the foreskin expander 2 of the first embodiment of the present invention can be made of plastic materials respectively, that is, the base component 1 and the foreskin expander 2 of the first embodiment of the present invention are plastic components respectively; specifically, the first base portion 11 and each abutment portion 12 of the base component 1 are injection molded into one piece by plastic material, and the second base portion 22 and each elastic expansion arm 21 of the foreskin expander 2 are injection molded into one piece by plastic material.

[0038] When the new foreskin expander of the first embodiment is used for foreskin expansion, the adjusting nut 4 is first tightened and the adjusting nut 4 and the large end 31 of the adjusting bolt 3 are gradually brought close to each other. During this process, the adjusting nut 4 and the large end 31 of the adjusting bolt 3 bring the first base 11 of the base member 1 and the second base 22 of the foreskin expander 2 close to each other. Since the foreskin expander 2 moves close to the base member 1 and each abutting portion 12 contacts and presses the rear end of each elastic expansion arm 21, the front end of each elastic expansion arm 21 is respectively deflected inwards, that is, the entire foreskin expander 2 is close to the base member 1. The front end portion contracts inwardly; after the front end portion of the entire foreskin expander 2 contracts inwardly into place, the front end portion of each elastic expansion arm 21 is respectively extended into the foreskin opening of the patient, and then the adjusting nut 4 is loosened. Under the action of the restoring elastic force of each elastic expansion arm 21, the second base 22 of the foreskin expander 2 moves away from the first base 11 of the base member 1, and the front end portion of each elastic expansion arm 21 swings outwardly. At this time, the front end portion of each elastic expansion arm 21 of the foreskin expander 2 physically stretches and expands the patient's foreskin, and this embodiment 1 can realize a staged gradual expansion operation.

[0039] It should be emphasized that the new foreskin expander of the present embodiment 1 is composed of only a base member 1, a foreskin expander 2, an adjusting nut 4 and an adjusting bolt 3. Compared with the prior art, the present embodiment 1 is simpler as a whole; in addition, when it needs to be disassembled and cleaned, it is only necessary to unscrew the adjusting nut 4 from the threaded rod 32 of the adjusting bolt 3 and withdraw the threaded rod 32 from the first through hole 13 and the second through hole 23. Compared with the prior art, the present embodiment 1 is easy to disassemble and clean; in addition, after disassembly and cleaning, it is only necessary to reinsert the threaded rod 32 of the adjusting bolt 3 into the first through hole 13 and the second through hole 23 and screw on the adjusting nut 4 to achieve assembly, and the assembly connection is convenient and quick.

[0040] Based on the above, it can be seen that through the above structural design, the new foreskin dilator of the first embodiment has the advantages of novel design, simple structure and easy disassembly and assembly.

[0041] Embodiment 2, as Figures 1 to 5 As shown, the difference between the second embodiment and the first embodiment is that the front end of each abutting top portion 12 is respectively provided with a limiting groove 14 opening forward, and the rear end of each elastic expansion arm 21 is respectively extended into the limiting groove 14 of the corresponding abutting top portion 12.

[0042] In the process of achieving expansion adjustment of the front end of each elastic expansion arm 21 through the adjustment structure composed of the adjustment bolt 3 and the adjustment nut 4, since the rear end of each elastic expansion arm 21 is respectively extended into the limit groove 14 of the corresponding abutment top part 12, the second embodiment can use the limit groove 14 to stop and limit the rotation of each elastic expansion arm 21 to avoid the foreskin expansion member 2 rotating relative to the base member 1 during use, causing the elastic expansion arm 21 to slip off from the front end of the corresponding abutment top part 12, thereby improving the stability and reliability of use.

[0043] Embodiment three, as Figures 1 to 5 As shown, the difference between the third embodiment and the first embodiment is that the new foreskin dilator also includes a silicone sleeve 5.

[0044] When the novel foreskin dilator is used, the front end of each elastic dilating arm 21 is respectively covered with a silicone sleeve 5 .

[0045] When the front end of each elastic expansion arm 21 is extended into the foreskin opening of the patient and the foreskin of the patient is physically expanded by the front end of each elastic expansion arm 21, each elastic expansion arm 21 contacts the foreskin of the patient through the silicone sleeve 5, which can effectively improve the comfort of the foreskin during expansion.

[0046] Embodiment 4, as Figures 1 to 3 As shown, the difference between the fourth embodiment and the first embodiment is that the foreskin expansion member 2 is provided with two elastic expansion arms 21, and the two elastic expansion arms 21 of the foreskin expansion member 2 are arranged opposite to each other.

[0047] Embodiment 5: The difference between the embodiment 5 and the embodiment 1 is that the foreskin expansion member 2 is provided with three (such as Figure 4 as shown) or four (as shown Figure 5 As shown in the figure, the elastic expansion arms 21 of the foreskin expansion member 2 are arranged in a circular array.

[0048] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
