Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a foreskin expander. 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] For example, Chinese patent CN2020108332068 discloses a foreskin dilator. This dilator can dilate the foreskin by adjusting multiple dilating flaps when the gripping part is grasped. However, this dilator is prone to slippage during use and may even cause injury to the penis of a boy. Secondly, the gripping part of this dilator is an independent structure, which, combined with the mounting structure on the dilating flaps, results in a long longitudinal length of the entire dilator, affecting its weight and hindering the miniaturization and lightweight requirements of instruments in foreskin dilation surgery. Furthermore, the structural design of this dilator is unreasonable, and the production and assembly process is relatively complex. Therefore, there is an urgent need for a foreskin dilator to solve the above problems. Utility Model Content

[0026] Reference Figures 1 to 2 A foreskin dilator includes a gripping part 10, a connecting seat 20, a driving head 30, a screw 40, an adjusting part 50, and a plurality of dilating flaps 60.
[0027] The expansion flap 60 is integrally formed on the grip portion 10 to form an expansion cavity 61;
[0028] At least a portion of the connecting seat 20 is housed within the grip portion 10 and is detachably connected to the grip portion 10;
[0029] The drive head 30 is disposed within the expansion cavity 61;
[0030] One end of the screw 40 is connected to the drive head 30, and the other end passes through the connecting seat 20;
[0031] The adjustment part 50 is connected to the other end of the screw 40 and is used to drive the drive head 30 to push the expansion petals 60 outward through the screw 40.
[0032] 1) In this utility model, preferably, the gripping part 10 is provided with a slot 71, and the connecting seat 20 is provided with a locking block 72 on the side near the gripping part 10 and a limiting block 73 on the side away from the gripping part 10. The locking block 72 can be locked into the slot 71 when the connecting seat 20 is inserted into the gripping part 10, and the limiting block 73 abuts against the end face of the gripping part 10. In a further embodiment, the expansion petals 60 are arranged at intervals along the circumference of the gripping part 10 to form the slot 71. During assembly, the screw 40 is first threaded onto the connecting seat 10. The drive head 30 is rotated onto the connector 20 until it abuts against the upper end face of the connector 20. Then, the locking block 72 of the connector 20 is arranged opposite to the locking groove 71 on the gripping part 10, and the connector 20 is pushed into the gripping part 10 until the locking block 72 is engaged in the locking groove 71, thus completing the connection between the connector 20 and the gripping part 10. At this time, the drive head 30 is located in the expansion cavity 61. In some embodiments, the expansion petal 60 is integrally formed on the gripping part 10, which can simplify the structure of the expander and also reduce the difficulty of production and assembly.
[0033] 2) During operation, first arrange the multiple expansion flaps 60 and make their front ends as close inward as possible, then align them with the foreskin opening and insert them until at least part of the expansion flap 60 enters the foreskin opening. Then, by rotating the adjustment part 50, the screw 40 and the drive head 30 will be driven to rotate. Since the screw 40 and the connecting seat 20 are connected by threads, the adjustment part 50, the screw 40 and the drive head 30 will rotate and move forward as a whole, causing the drive head 30 to push the expansion flap 60, and finally causing the expansion flap 60 to open outward, thus completing the expansion of the foreskin.
[0034] 3) In some embodiments, one end of the screw 40 is integrally formed with the drive head 30; this simplifies the structure of the expander and also reduces the difficulty of production and assembly.
[0035] 4) In some embodiments, the adjustment part 50 is connected to the other end of the screw 40 via a pin structure 80.
[0036] 5) In some embodiments, a first anti-slip stripe 11 is provided on the outer wall of the gripping part 10; this setting can increase the friction when the doctor grips the gripping part 10 and prevent slippage during the operation; further, a second anti-slip stripe 62 is provided on the outer wall of the dilation valve 60; this setting can increase the friction between the dilation valve 60 and the foreskin lining and prevent the dilation valve 60 from slipping out of the foreskin.
[0037] 6) In some embodiments, a foreskin dilator further includes a tether 91 and a pull ring 92. One end of the tether 91 is connected to the adjustment part 50 and the other end is connected to the pull ring 92. Specifically, when using the dilator, the doctor can insert his finger into the pull ring 92 to further prevent slippage. The doctor can also wrap the tether 91 around the front end of the dilator 60 to pull the dilator 60 inward and close it when the front end of the dilator 60 is not closed enough, thereby further improving the convenience of using the dilator.
[0038] 7) The advantages of this utility model are: the above structure can not only reduce the complexity of production and assembly, but also the overall structure is small, which can meet the requirements of miniaturization and lightweighting of instruments in circumcision, and has very good practicality.
[0039] 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.
