Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a foreskin dilator that can be easily inserted. Background Technology

[0002] Phimosis is a common condition in children. In children, phimosis occurs because the foreskin opening is narrow or the foreskin is adhered to the glans penis, preventing the foreskin from being retracted to expose the urethral opening and glans penis. Current treatment methods for phimosis mainly include circumcision and foreskin dilation surgery. Circumcision, however, inevitably causes trauma to the patient, and it is sometimes difficult to control the extent of removal, causing pain to the child and easily leading to complications.

[0003] Because children's foreskin openings are relatively narrow, foreskin dilators are difficult to insert into the foreskin during the first expansion. For example, Chinese Patent CN2023106993712 discloses a foreskin dilator and foreskin dilator method. This dilator solves the problem of difficulty in insertion by setting extension parts of different lengths. Although this dilator is easier to insert into the foreskin opening, the different lengths of the extension parts also cause uneven force on the penis during the initial dilation, reducing the dilation effect. Furthermore, the dilator flap has certain edges, and the different lengths of the extension parts increase the risk of damage to the foreskin lining. Therefore, there is an urgent need for a foreskin dilator that is easy to insert to solve the above problems. Utility Model Content

[0033] Reference Figures 1 to 3 A foreskin dilator that is easy to insert includes a gripping part 100, a driving assembly 200, an insertion head 300, a traction member 400, and a plurality of 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 utility model, during operation, firstly, multiple expansion flaps 500 are arranged and their front ends are retracted 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 drive assembly 200 includes a connecting seat 210, a drive head 220, a screw 230, and an adjusting part 240; at least a portion of the connecting seat 210 is housed within the holding part 100 and detachably connected to the holding part 100; the drive head 220 is disposed within the expansion cavity 600; one end of the screw 230 is connected to the drive head 220, and the other end passes through the connecting seat 210; the adjusting part 240 is connected to the other end of the screw 230 and is used to drive the drive head 220 to push the expansion petal 500 outward through the screw 230; in some embodiments, the expansion petal 500 is integrally formed on the holding part 100, which can simplify the structure of the expander and also reduce the difficulty of production and assembly.

[0041] Specifically, rotating the adjustment part 240 will drive the screw 230 and the drive head 220 to rotate. Since the screw 230 and the connecting seat 210 are connected by a thread, the adjustment part 240, the screw 230 and the drive head 220 will rotate and move forward as a whole, causing the drive head 220 to push the expansion petal 500, and finally causing the expansion petal 500 to open outward, thus completing the expansion of the foreskin.

[0042] 3) In some embodiments, the gripping part 100 is provided with a slot 710, and the connecting seat 210 is provided with a locking block 720 on the side near the gripping part 100 and a limiting block 730 on the side away from the gripping part 100. The locking block 720 can be locked in the slot 710 when the connecting seat 210 is inserted into the gripping part 100, and the limiting block 730 abuts against the end face of the gripping part 100. In a further embodiment, the expansion petals 500 are arranged at intervals along the circumference of the gripping part 100 to form the slot 710.

[0043] Specifically, during assembly, first connect the screw 230 to the connecting seat 210 and rotate it until the drive head 220 abuts against the upper end face of the connecting seat 210. Then, arrange the locking block 720 of the connecting seat 210 opposite to the locking groove 710 on the holding part 100, and push the connecting seat 210 into the holding part 100 until the locking block 720 is engaged in the locking groove 710, thus completing the connection between the connecting seat 210 and the holding part 100. At this time, the drive head 220 is located in the expansion cavity 600.

[0044] 4) In some embodiments, one end of the screw 230 is integrally formed with the drive head 220; this simplifies the structure of the expander and also reduces the difficulty of production and assembly.

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

[0046] 6) In some embodiments, a first anti-slip stripe 910 is provided on the outer wall of the gripping part 100; this provision can increase the friction when the doctor grips the gripping part 100 and prevent slippage during the operation; further, a second anti-slip stripe 920 is provided on the outer wall of the dilation valve 500; this provision can increase the friction between the dilation valve 500 and the foreskin lining and prevent the dilation valve 500 from slipping out of the foreskin.

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

[0048] 8) The advantages of this utility model are: the above structure not only makes it very easy to insert into the foreskin opening for expansion, but also ensures that the force is evenly distributed in all aspects during expansion, which improves the convenience of operation and reduces the risk of damage to the foreskin lining, thus meeting the needs of use.

[0049] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
