Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a foreskin dilator convenient to operate. BACKGROUND

[0002] Phimosis is a common disease in children. Children's phimosis is caused by narrow preputial orifice or adhesion of prepuce to glans penis, which leads to the inability of prepuce to turn back to expose the urethral orifice and glans penis. The current treatment methods for phimosis mainly include preputiectomy and prepuce dilation surgery. Preputiectomy will inevitably cause trauma to the patient, and sometimes it is difficult to control the extent of resection, causing pain to the child and easily causing complications.

[0003] Because the preputial orifice of children is relatively narrow, the prepuce of children will cause the foreskin dilator to be difficult to enter and insert into the inner plate of the prepuce during the first dilation. For example, a foreskin dilation device and method are disclosed in Chinese patent CN2023106993712. The dilation device solves the problem of difficult insertion by providing different lengths of insertion portions. Although this dilation device is easier to insert into the preputial orifice, the different lengths of the insertion portions also cause uneven stress on the penis during early dilation, reducing the dilation effect. Furthermore, the dilation petals have certain edges, and the different lengths of the insertion portions increase the risk of damage to the inner membrane of the prepuce. Therefore, there is an urgent need for a foreskin dilator convenient to operate to solve the above problems. SUMMARY

[0033] Reference Figs. 1 to 3 A convenient foreskin dilator includes a holding part 100, a driving assembly 200, an insertion head 300, a traction member 400, and several dilation flaps 500.

[0034] The expansion flap 500 is connected to the front end of the gripping part 100 and forms an expansion cavity 600;

[0035] The drive assembly 200 is mounted on the gripping part 100 and is used to drive the expansion petal 500 to open outward;

[0036] The insertion head 300 is positioned at the front end of the dilation valve 500;

[0037] The traction member 400 passes through the holding part 100 and the expansion cavity 600 and is connected to the insertion head 300;

[0038] The drive assembly 200 can push the dilation valve 500 outward when the insertion head 300 is inserted into the foreskin opening, so that the traction member 400 pulls the insertion head 300 to be received in the dilation cavity 600.

[0039] 1) In this invention, during operation, firstly, multiple expansion flaps 500 are arranged and their front ends are brought inward as much as possible. Then, the insertion head 300 is pulled by the traction member 400 to abut against the front ends of the multiple expansion flaps 500. After preparation, the insertion head 300 is aligned with the foreskin opening and inserted until the insertion head 300 is completely inside the foreskin opening and at least a portion of the expansion flaps 500 is inside the foreskin opening. Then, the driving component 200 drives the expansion flaps 500 to open outward, thereby expanding the foreskin. It should be noted that the minimum outer diameter formed by the expansion flaps 500 is smaller than the maximum outer diameter of the insertion head 300, so as to avoid the expansion flaps 500 being blocked by the retraction of the foreskin after the insertion head 300 is completely inside the foreskin opening, which can further improve the convenience of insertion into the foreskin opening.

[0040] 2) In some embodiments, the driving assembly 200 comprises a connecting seat 210, a driving head 220, a screw rod 230 and an adjusting part 240; at least part of the connecting seat 210 is accommodated in the holding part 100 and is detachably connected to the holding part 100; the driving head 220 is arranged in the expansion cavity 600; one end of the screw rod 230 is connected to the driving head 220 and the other end is threaded through the connecting seat 210; the adjusting part 240 is connected to the other end of the screw rod 230 and is used for driving the driving head 220 to push the expansion petals 500 outwardly; in some embodiments, the expansion petals 500 are integrally formed on the holding part 100, which can simplify the structure of the dilator and also reduce the production difficulty and assembly difficulty.

[0041] Specifically, rotating the adjusting part 240 will drive the screw rod 230 and the driving head 220 to rotate, and since the screw rod 230 is threadedly connected to the connecting seat 210, the adjusting part 240, the screw rod 230 and the driving head 220 will integrally rotate and move forward, so that the driving head 220 pushes the expansion petals 500, and finally the expansion petals 500 are expanded outwardly, completing the expansion of the foreskin.

[0042] 3) In some embodiments, the holding part 100 is provided with a clamping groove 710, the connecting seat 210 is provided with a clamping block 720 on the side close to the holding part 100 and a limiting block 730 on the side away from the holding part 100, the clamping block 720 can be clamped in the clamping groove 710 when the connecting seat 210 is inserted into the holding part 100, and the limiting block 730 abuts against the end face of the holding part 100; in further embodiments, the expansion petals 500 are arranged along the circumference of the holding part 100 to form the clamping groove 710.

[0043] Specifically, during assembly, the screw rod 230 is threadedly connected to the connecting seat 210 and rotated to abut the driving head 220 against the upper end face of the connecting seat 210, then the clamping block 720 of the connecting seat 210 is arranged opposite to the clamping groove 710 on the holding part 100, and the connecting seat 210 is pushed into the holding part 100 until the clamping block 720 is clamped in the clamping groove 710, completing the connection between the connecting seat 210 and the holding part 100, and at this time the driving head 220 is located in the expansion cavity 600.

[0044] 4) In some embodiments, one end of the screw rod 230 is integrally formed with the driving head 220; which can simplify the structure of the dilator and also reduce the production difficulty and assembly difficulty.

[0045] 5) In some embodiments, the other end of the screw rod 230 is connected to the adjusting part 240 through a limiting pin shaft 800.

[0046] 6) In some embodiments, the outer wall of the holding part 100 is provided with first anti-skid stripes 910; this arrangement can increase the friction when the doctor holds the holding part 100, avoiding slipping during the operation; further, the outer wall of the expansion flap 500 is provided with second anti-skid stripes 920; this arrangement can increase the friction between the expansion flap 500 and the inner prepuce, avoiding the expansion flap 500 slipping out of the inner prepuce.

[0047] 7) In some embodiments, the traction member 400 is arranged as a pull rope.

[0048] 8) The advantages of the present application are that the above-mentioned structure can not only be very convenient for insertion into the prepuce opening for expansion, but also the stress is relatively uniform in all aspects during expansion, which can improve the operation convenience while reducing the risk of damage to the inner prepuce, meeting the use requirements.
