Description

Technical Field

[0001] This utility model relates to a disposable support head for a 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 avoid 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. Currently, speculum on the market are not disposable products and need to be thoroughly sterilized before each use. Sterilization takes a certain amount of time and steps, and sometimes when there are many patients, the sterilization time of the speculum seriously affects the speed of the examination.

[0003] Therefore, it is necessary to further improve the expanders available on the market. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a disposable support head for a foreskin expander. The expander uses a disposable support head that can be detached and replaced, eliminating the need for sterilization and saving sterilization time.

[0005] To achieve the above objectives, we provide a disposable support head for a foreskin expander, which includes a support head, a base, an expansion head, and a push rod. The support head includes a connecting part and multiple expansion flaps. The base has a threaded through hole extending from front to back at the middle position. The push rod is screwed into the threaded through hole, and the front end of the push rod extends out of the base and connects to the expansion head. The front end of the base has a connecting step, and the connecting part is sleeved on the connecting step and threadedly connected and fixed thereto.

[0006] In one or more embodiments, the outer peripheral wall of the connecting step is provided with an external thread structure, and the inner wall of the connecting part is provided with an internal thread structure that mates with the external thread structure.

[0007] In one or more embodiments, the height of the connecting portion is 5-8 mm.

[0008] In one or more embodiments, the push rod is provided with a handle at the connection end of the expansion head, and a first anti-slip structure is provided on the outer peripheral wall of the handle. The first anti-slip structure is composed of a plurality of circumferentially evenly distributed first ribs.

[0009] In one or more embodiments, the handle is fixed to the push rod by screws.

[0010] In one or more embodiments, the outer peripheral wall of the base is provided with a second anti-slip structure, which is composed of a plurality of circumferentially evenly distributed second ribs.

[0011] In one or more embodiments, the base, expansion head, and push rod are made of stainless steel; the connecting part and the plurality of expansion flaps are injection molded as a single unit.

[0012] In one or more embodiments, a third anti-slip structure is provided on the outer peripheral wall of the connecting portion.

[0013] Compared with the prior art, this utility model has the following technical effects: the support head and the base are fixed by threaded connection, the support head can be made of disposable material, and the support head can be removed and discarded into the medical waste bin after each use. When it is used again, a new support head can be directly replaced. These support heads can be sterilely and individually packaged for easy storage and use, saving the sterilization time of the support head and improving the efficiency of medical treatment.

[0015] Figure 2 This is an exploded view of the foreskin expander of this utility model. Detailed Implementation

[0016] 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.

[0017] Please refer to Figure 1-2 This application provides a disposable foreskin dilator head, comprising a head 1, a base 2, a dilator head 3, and a push rod 4. The head includes a connecting part 11 and multiple dilator flaps 12. The base 2 has a threaded through hole at its center, and the push rod 4 is screwed into the threaded through hole. The front end of the push rod 4 extends out of the base 2 and connects to the dilator head 3. By rotating the push rod, it moves forward relative to the base, causing the dilator head to move forward and open the dilator flaps. The front end of the base has a connecting step 5, and the connecting part 11 is sleeved on the connecting step and threadedly connected and fixed thereto. After each use, the head is disassembled and disposed of in a designated medical waste bin. A new head is then installed for use when the next patient needs examination. With this structure, the head of the dilator can be sterilely and individually packaged, making it convenient to open for each use and saving the step of head sterilization, thus improving examination efficiency.

[0018] Specifically, the outer peripheral wall of the connecting step is provided with an external thread structure 6, and the inner wall of the connecting part 11 is provided with an internal thread structure 7 that mates with the external thread structure. The height of the connecting part 11 is 5-8mm, preferably 6mm, to ensure that the connecting part and the connecting step have a certain connection area and to ensure that the support head is not easy to loosen after installation.

[0019] The push rod 4 has a handle 8 at the connection end with the expansion head. The outer peripheral wall of the handle has a first anti-slip structure, which consists of multiple circumferentially distributed first protruding ribs 9. The handle allows the user to easily rotate the push rod. The handle 8 is specifically fixed to the push rod 4 with screws.

[0020] The outer peripheral wall of the base 2 is provided with a second anti-slip structure, which consists of multiple circumferentially evenly distributed second ribs 10, making it less likely for the user to slip when holding the base.

[0021] The base 2, expansion head 3, and push rod 4 are made of stainless steel. Stainless steel has the advantages of corrosion resistance, water resistance, high structural strength, and easy cleaning. The connecting part 11 and multiple expansion petals 12 are injection molded as a single unit. The injection molded support head has low cost and good expansion elasticity.

[0022] The outer peripheral wall of the connecting part 11 is provided with a third anti-slip structure 13, which can prevent slippage when the user installs and disassembles the connecting part.

[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.
