Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a foreskin dilator which is easy to operate. Background Art

[0002] Phimosis is a common disease in children. Children have phimosis because the foreskin opening is narrow or the foreskin is adhered to the glans penis, which makes the foreskin unable to be turned back to expose the urethral opening and glans penis. The current treatments for phimosis mainly include circumcision and foreskin dilation. Circumcision will bring inevitable trauma to the patient, and sometimes it is difficult to control the degree of resection, which brings pain to the child and is also prone to complications.

[0003] Since the foreskin opening of children is relatively narrow, the foreskin of children will make it difficult for the foreskin dilator to enter and be inserted into the inner plate of the foreskin during the first expansion. For example, Chinese patent CN2023106993712 discloses a foreskin expansion device and a foreskin expansion method. The expansion device solves the problem of difficult insertion by setting an insertion part of different lengths; although this expansion device is easier to insert into the foreskin opening, it is also due to the different lengths of the insertion part that the penis is unevenly stressed during the early expansion, reducing the expansion effect; furthermore, the expansion flap has certain edges and angles, and the different lengths of the insertion part will increase the risk of damage to the foreskin lining; therefore, there is an urgent need for a foreskin dilator that is easy to operate to solve the above problems.

[0033] Reference Figures 1 to 3 , a conveniently operated foreskin dilator, comprising a gripping portion 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 holding portion 100 and encloses an expansion cavity 600;

[0035] The driving assembly 200 is mounted on the holding portion 100 and is used to drive the expansion valve 500 to open outwards;

[0036] The insertion head 300 is disposed at the front end of the expansion flap 500;

[0037] The traction member 400 is disposed in the holding portion 100 and the expansion cavity 600 and is connected to the insertion head 300;

[0038] The driving assembly 200 can push the expansion flap 500 to open outward when the insertion head 300 is inserted into the foreskin opening, so that the pulling member 400 pulls the insertion head 300 to be accommodated in the expansion cavity 600 .

[0039] 1) In the present invention, during operation, firstly, the plurality of expansion flaps 500 are arranged and their front ends are folded inward as much as possible, and then the insertion head 300 is pulled by the traction member 400 to abut against the front ends of the plurality of expansion flaps 500. After preparation, the insertion head 300 is aligned with the foreskin opening and inserted until the insertion head 300 completely enters the foreskin opening and at least part of the expansion flaps 500 enters the foreskin opening, and then the expansion flaps 500 are driven to open outward by the drive assembly 200, thereby expanding the foreskin. It should be noted that the minimum outer diameter enclosed 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 due to the retraction of the foreskin after the insertion head 300 completely enters the foreskin opening, thereby further improving the convenience of insertion into the foreskin opening.

[0040] 2) In some embodiments, the drive assembly 200 includes a connecting seat 210, a driving head 220, a screw 230 and an adjusting portion 240; at least a portion of the connecting seat 210 is accommodated in the holding portion 100 and is detachably connected to the holding portion 100; the driving head 220 is disposed in the expansion chamber 600; one end of the screw 230 is connected to the driving head 220, and the other end is passed through the connecting seat 210; the adjusting portion 240 is connected to the other end of the screw 230, and is used to drive the driving head 220 to push the expansion flap 500 to open outward through the screw 230; in some embodiments, the expansion flap 500 is integrally formed on the holding portion 100, which can simplify the structure of the expander, while also reducing the difficulty of production and assembly.

[0041] Specifically, when the adjusting portion 240 is rotated, the screw 230 and the driving head 220 will be driven to rotate. Since the screw 230 and the connecting seat 210 are threadedly connected, the adjusting portion 240, the screw 230 and the driving head 220 will rotate and move forward as a whole, so that the driving head 220 pushes the expansion flap 500, and finally the expansion flap 500 opens outward, completing the expansion of the foreskin.

[0042] 3) In some embodiments, a card slot 710 is provided on the holding portion 100, a card block 720 is provided on the side of the connecting seat 210 close to the holding portion 100, and a limit block 730 is provided on the side away from the holding portion 100. The card block 720 can be engaged in the card slot 710 when the connecting seat 210 is inserted into the holding portion 100, and the limit block 730 abuts against the end face of the holding portion 100; in a further embodiment, the expansion petals 500 are arranged at intervals along the circumference of the holding portion 100 to form the card slot 710.

[0043] Specifically, during assembly, the screw 230 is first threadedly connected to the connecting seat 210 and rotated until the drive head 220 abuts against the upper end surface of the connecting seat 210, and then the block 720 of the connecting seat 210 is arranged relative to the slot 710 on the holding portion 100, and the connecting seat 210 is pushed into the holding portion 100 until the block 720 is engaged in the slot 710, completing the connection between the connecting seat 210 and the holding portion 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 rod 230 is integrally formed with the drive head 220; this can simplify the structure of the expander and also reduce the difficulty of production and assembly.

[0045] 5) In some embodiments, the other end of the screw rod 230 is connected to the adjustment portion 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 holding portion 100; this setting can increase the friction when the doctor grasps the holding portion 100 to prevent slipping during the operation; further, a second anti-slip stripe 920 is provided on the outer wall of the expansion flap 500; this setting can increase the friction between the expansion flap 500 and the foreskin lining to prevent the expansion flap 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 the present invention are: the above structure can not only be easily inserted into the foreskin opening for expansion, but also the forces in all directions are relatively uniform during expansion, which improves the convenience of operation and reduces the risk of damage to the foreskin lining, thus meeting the use requirements.

[0049] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
