Referring to fig. 1 and 2, the genital prepuce extension device of the present embodiment includes: a grip portion 100; a plurality of expansion petals 220 circumferentially disposed on the grip portion 100, the expansion petals 220 extending gradually inward in a direction away from the grip portion 100; and an adjusting device provided on the grip part 100 for adjusting the expansion angle of the plurality of expansion petals 220.

By applying the genital prepuce expansion device of the embodiment, when the prepuce expansion operation is performed, the contracted tail ends of the expansion flaps 220 can be inserted into the middle of the prepuce by holding the holding part 100 by hand, and then the adjustment device is controlled to slowly open the expansion flaps 220 to open the prepuce, and when the opening angle is too large, the adjustment device can be controlled to reduce the opening angle of the expansion flaps 220 for flexible application; because the expansion flap 220 is contracted towards the direction far away from the body 210, in the process of expanding the foreskin, the inclined plane of the outer wall of the expansion flap 220 directly acts on the surface of the foreskin and cannot be embedded into the foreskin, so that the condition that the foreskin is easily damaged when the foreskin is expanded by adopting the expansion rod in the prior art is effectively improved, and the pain born by a patient is reduced.

The adjusting device can adjust the expansion angle of the expansion petals 220 in various ways, for example, a sliding groove is formed in the inner wall of the expansion petals 220, a sliding block in sliding fit with the sliding groove is arranged, the plurality of expansion petals 220 are pushed open by forward movement of the sliding block, a pushing block capable of moving outwards can be arranged on the holding part 100, and the expansion petals 220 are directly opened outwards by the pushing block.

Specifically, as shown in fig. 3 and 4, the genital prepuce extension device comprises a genital prepuce extension member, the genital prepuce extension member is arranged on the holding portion 100, the genital prepuce extension member at least comprises a plurality of extension petals 220, the extension petals are arranged on the holding portion 100 in a surrounding manner, and the plurality of extension petals 220 are gathered inwards like unopened petals, so that the outer contour of the genital prepuce extension member is tapered, and the taper direction is far away from the holding portion 100.

As shown in fig. 1, the genital prepuce expander can be used with the grip portion 100 and the adjustment device, or used separately from the grip portion 100 and the adjustment device, or used by placing the expander assembly on other surgical instruments, etc.

In order to facilitate the installation of the plurality of expansion flaps 220 on the holding part 100, the genital prepuce expansion member may further include a body 210, the body 210 is sleeved on the holding part 100, and the plurality of expansion flaps 220 are arranged on the body 210 in a surrounding manner; in order to ensure that the expansion petals 220 can generate inward elastic force when being expanded, the expansion petals 220 can automatically retract when the expansion angle is too large, and the expansion angle is reduced; the plurality of expansion flaps 220 may be integrally provided with the body 210, and the plurality of expansion flaps 220 generate an inward elastic force when being expanded by the elasticity of the material itself; or elastic hinges are arranged on the body 210, so that the expansion flaps 220 are hinged to the body 210 through the elastic hinges, and at this time, the elastic hinges can apply elastic force to the expansion flaps 220, so that the expansion flaps 220 can extend inwards.

Of course, to avoid the adjustment device, the body 210 may be perforated back and forth such that the adjustment device may pass inside the body 210.

As shown in fig. 3 and 4, in order to facilitate adjustment of the opening angle of the expansion petals 220, the adjustment device includes a top block 130 disposed inside the plurality of expansion petals 220, the top block 130 being capable of moving forward to abut against the expansion petals 220 and open the plurality of expansion petals 220; when the top block 130 moves forwards, the expansion valve 220 is opened by the abutment of the top block 130, and when the top block 130 moves backwards, the expansion valve 220 loses the abutment of the top block 130 and can be automatically closed; when the expansion device needs to be used repeatedly, the top block 130 only needs to be reset, so that the expansion flap 220 is folded to the initial position, and then the expansion flap 220 is taken out of the foreskin.

Further, since the expansion flaps 220 gradually extend inward in a direction away from the grip portion 100; within a certain range, the longer the distance that the top block 130 moves forward, the larger the opening angle of the expansion flap 220; therefore, the opening angle of the expansion valve 220 can be flexibly controlled according to the forward movement position of the top block 130.

Further, a screw 110 is in threaded fit with the holding portion 100, and the screw 110 is connected with the top block 130; when the top block 130 needs to be controlled to move previously and the opening angle of the expansion valve 220 is adjusted, the screw 110 is only required to be rotated, so that the screw 110 drives the top block 130 to move back and forth; because the screw rod 110 has reverse self-locking performance, when the top block 130 stops moving, the screw rod 110 can automatically lock the top block 130 at the current position, and the situation that the expansion valve 220 is contracted due to retraction of the top block 130 after adjustment is completed so as to cause failure in placement of the expansion device is prevented.

In order to facilitate the twisting of the screw rod 110, a hand wheel 120 may be disposed on the screw rod 110, and a plurality of grooves extending in the front-rear direction may be distributed on the hand wheel 120, so as to facilitate the increase of friction when the hand wheel 120 is rotated.

As shown in fig. 3 and 4, a reducing section 230 is arranged at one end of the expansion valve 220 away from the grip part 100; specifically, as shown in fig. 3, in the constricted section 230, the outer diameter of a part surrounded by the plurality of expansion flaps 220 is smaller than the outer diameter surrounded by the expansion flaps 220 at the front and rear ends of the constricted section 230, during the expansion of the foreskin by the expansion flaps 220, the foreskin slides along the outer wall of the expansion flaps 220 away from the holding part 100, when the edge of the foreskin slides to the constricted section 230, the protrusion at the front side of the constricted section 230 can block the foreskin from further sliding out, so that the expansion flaps 220 can be fixed inside the foreskin, and when no additional clamping device is needed, the expansion flaps 220 can be ensured to stably expand the foreskin for a long time, thereby facilitating parents to place children in self-behaviors in the home dilator.

As shown in fig. 1 and 2, the expansion valve further comprises an elastic ring 310, the elastic ring 310 is sleeved on the periphery of the plurality of expansion valves 220, and the elastic ring 310 abuts against the plurality of expansion valves 220; when the expansion flaps 220 are repeatedly expanded and are not elastic enough, the elastic ring 310 can hoop around the plurality of expansion flaps 220 to provide elasticity for the expansion flaps 220.

Wherein, in order to prevent the elastic ring 310 from sliding out of the expansion valve 220, a convex rib 221 is arranged on the outer wall of the expansion valve 220, the convex rib 221 extends along the front-back direction, and the elastic ring 310 can abut against the surface of the convex rib 221.

To prevent sharp distal ends of the expansion flap 220 during placement of the expansion flap 220 onto the foreskin. The glans body 210 may be scratched, and an outwardly convex flange may be provided at an end of the expansion flap 220 away from the body 210.
