Description

Technical Field

[0001] This utility model relates to an easy-to-operate foreskin expander. Background Technology

[0002] Some men have phimosis (tight foreskin), so it is recommended that men of a certain age have a relevant examination at the hospital and have the excess foreskin cut to prevent inflammation and affect normal erectile function. During the examination, the doctor usually uses a speculum to separate the foreskin and glans to determine the length of foreskin that needs to be cut. Current speculum dilates the foreskin slowly due to its threaded insertion method, making it suitable for cases where the foreskin and glans are adhered. However, when there is no adhesion, the slow threaded insertion speed affects the doctor's consultation and surgical efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned problems. We provide an easy-to-operate foreskin dilator that uses a direct-push dilation method and has the advantage of fast dilation speed.

[0004] To achieve the above objectives, we provide an easy-to-operate foreskin dilator, which includes multiple dilators, a push rod, and a dilator head. Each dilator includes a base and multiple dilators disposed on the base. The multiple dilators are evenly distributed circumferentially at the front end of the base and are in a contracted state. The dilator head is disposed at the front end of the base and is located inside the multiple dilators. The base has holes for the push rod to pass through. The push rod passes through the base and connects to the dilator head. The outer wall of the push rod has multiple locking parts distributed at intervals along its length. The holes have clearance openings corresponding to the locking parts. The locking parts can be rotated by the push rod to offset from the clearance openings and engage with the upper edge of the clearance openings.

[0005] In one or more embodiments, the base has an upwardly extending limiting portion on the upper edge side of the clearance opening.

[0006] In one or more embodiments, a spring is provided between the expansion head and the base.

[0007] In one or more embodiments, both the expansion head and the base have annular grooves, and the two ends of the spring are respectively embedded in the annular grooves of the expansion head and the base.

[0008] In one or more embodiments, the outer side wall of the base is provided with a plurality of circumferentially evenly distributed raised ribs.

[0009] In one or more embodiments, the push rod has a handheld portion at the other end relative to the expansion head.

[0010] In one or more embodiments, an arc-shaped transition surface is provided at both the upper outer edge and the lower outer edge of the card portion.

[0011] Compared with the prior art, this utility model has the following technical effects: the foreskin expander has the advantages of being easy to use and having a fast expansion speed. It can switch the expansion speed according to the doctor's operation, and is very suitable for some cases where the foreskin and glans are not adhered. It can improve the doctor's examination speed and shorten the operation time. Attached Figure Description

[0015] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0016] Please refer to Figure 1-3 This application provides an easy-to-operate foreskin dilator, which includes multiple dilators, a push rod 1, and a dilator head 2. Each dilator includes a base 3 and multiple dilator flaps 4 disposed on the base. The multiple dilator flaps are evenly distributed circumferentially at the front end of the base and are in a constricted state. The dilator head 2 is disposed at the front end of the base 3 and located inside the multiple dilator flaps 4. The base 3 has holes 5 for the push rod to pass through. The push rod passes through the base and connects to the dilator head 2. Pushing the dilator head forward with the push rod can open the multiple dilator flaps. The outer wall of the push rod 1 has multiple locking parts 6 spaced apart along its length, with the holes corresponding to the locking parts. The position has an opening 7 for the obstruction. The locking part can be rotated by the push rod to displace the obstruction and engage with the upper edge 71 of the obstruction 7. In specific operation, one hand holds the base and the other hand pushes the push rod to expand the dilation flap outward, thereby opening the foreskin. When it is expanded to a certain size, the current expansion size can be fixed by rotating the push rod to displace the locking part with the obstruction. During the expansion process, the push rod can be pushed quickly to open the dilation flap, or the push rod can be pushed slowly to open the dilation flap slowly, so that the doctor can adjust the opening speed of the dilation flap according to the actual situation during actual operation.

[0017] The base 3 has an upwardly extending limiting part 8 on the upper edge of the clearance opening. The limiting part can restrict the rotation direction of the push rod so that after expansion is completed, the push rod can be rotated back. The limiting part is used to position the locking part and the clearance opening to achieve quick alignment, so that the expansion head can be pulled back.

[0018] A spring 9 is provided between the expansion head 2 and the base 3. Since the expansion petals will apply pressure to the expansion head when they go from the open state to the closed state, the spring can provide a certain buffer force to prevent the expansion head from pulling back too quickly, so that the expansion head can be pulled back slowly.

[0019] Both the expansion head 2 and the base 3 have annular grooves 10. The two ends of the spring are respectively embedded in the annular grooves of the expansion head and the base. The annular grooves play a certain positioning role for the spring and can prevent the spring from shifting.

[0020] The outer wall of the base 3 is provided with multiple circumferentially evenly distributed protruding ribs 11. The multiple protruding ribs form an anti-slip structure, which can prevent slipping and allow the operator to firmly fix the base.

[0021] To facilitate the operator's rotation of the push rod, a handhold 12 is provided on the other end of the push rod 1 relative to the expansion head. The handhold is composed of two pieces that are disposed opposite to each other on the push rod.

[0022] The card part 6 has an arc-shaped transition surface 13 at both the upper outer edge and the lower outer edge to facilitate the card part passing through and exiting the clearance opening.

[0023] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
