Description

Technical Field

[0001] The present application relates to a phimosis treatment device, in particular to a phimosis treatment device suitable for patients of all ages. Background Art

[0002] This application is suitable for treating phimosis. Phimosis refers to the narrow opening of the foreskin (the skin covering the glans penis), or the adhesion of the foreskin to the glans penis, so that the foreskin cannot be turned up, and the external urethral opening and the glans penis cannot be exposed. Normally, it is physiological phimosis within 3 years old. After 3 years old, the foreskin opening of some boys will loosen by themselves, and most boys can turn up the foreskin at the age of five. However, in some boys' cases, turning up the foreskin by force will leave scars, and not paying attention to hygiene will cause inflammation or infection, which may cause pathological phimosis, and the foreskin cannot be turned up even after adulthood. Some male children also suffer from occlusive dry balanitis, a chronic dermatitis that can cause foreskin scarring and atrophy. This disease can involve the urinary tract, urethra and urethral opening, leading to urethral stenosis. Male children with pathological phimosis will have complications such as erectile pain, urine deviation, urine splashing, urinary tract infection, and repeated foreskin infection.

[0003] As for the treatment of phimosis, existing technologies include circumcision. However, circumcision may not be recommended for children with phimosis. Instead, physical methods of stretching the foreskin and turning it back are used in combination with topical medications. The more recommended approach is to repeat the physical therapy one or more times a day, and through a continuous course of treatment for a period of time, the phimosis problem can be gradually alleviated until it is completely resolved.

[0004] There is no doubt that physical manipulation therapy is an ideal and safe choice for most patients, but there are obstacles to this program in practice, mainly including: the program needs to be repeated once or multiple times a day and needs to last for a period of time. Patients prefer to complete the operation conveniently in a home environment, but for patients, they lack medical knowledge. At this time, convenient and safe specific devices are necessary; and because most of these patients are growing boys, preferably, the treatment device also needs to adapt to the changes in different tissue volumes during the growth period.

[0005] The prior art also explores similar home treatment devices, such as the solution disclosed in patent CN112741949A, but this type of solution only focuses on how to pull open the foreskin to achieve expansion and relieve the patient's pain. The functional design requirements in terms of convenience, safety and long-term versatility of device operation are still not met. Summary of the invention

[0055] Various exemplary embodiments of the present application are described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is by no means intended to limit the present application and its application or use. The present application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present application thorough and complete and to fully express the scope of the present application to those skilled in the art. It should be noted that unless otherwise stated, the relative arrangement of the components and steps, numerical expressions, and numerical values, etc., described in these embodiments should be interpreted as being merely exemplary, rather than as limitations.

[0056] The words “include” or “comprising” and the like used in this application mean that the elements preceding the words include the elements listed after the words, and do not exclude the possibility of also including other elements.

[0057] All terms (including technical terms or scientific terms) used in this application have the same meaning as those understood by ordinary technicians in the field to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be understood to have meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined in this article.

[0058] Components not described in detail in this section, parameters such as specific models of components, relationships between components, and control circuits may be considered as technologies, methods, and equipment known to ordinary technicians in the relevant fields, but in appropriate circumstances, such technologies, methods, and equipment should be considered as part of the specification.

[0059] The following reference Figure 1-4 The phimosis treatment device of the present application is described in detail. Figure 1 is a cross-sectional view of the initial state of the phimosis treatment device. Figure 2 It is a cross-sectional view of the phimosis treatment device in the working state. The phimosis treatment device of the present application comprises a dilator 2, a dilator driving unit 3, a support member 4 and a support member driving unit 5. Figure 3 is a schematic diagram of the structure of the elastic expansion component 21, Figure 4 31 is a schematic structural diagram of the expander propulsion unit 31.

[0060] See also Figure 1 The phimosis treatment device of the present application is used to probe into and expand the target part, and the expansion of the foreskin opening is used as an example for explanation. The phimosis treatment device comprises an outer sheath 1, a dilator 2, and a dilator driving unit 3.

[0061] For ease of explanation, this application takes the extension direction of the outer sheath 1 shown in the figure as the axial direction, the direction perpendicular to the axial direction as the radial direction, the axial insertion end, i.e., one end where the dilator 2 is installed, as the front end, and the other end as the rear end. Unless otherwise specified below, the expression of direction is the same.

[0062] In this embodiment, the outer sheath 1 has an inner cavity that penetrates along the axial direction, and the dilator 2 includes an elastic dilating component 21 that can at least partially penetrate into the target site. The dilator driving unit 3 includes a dilator propulsion unit 31 .

[0063] As an example, the expander drive unit 3 further includes a first drive handle 331, a first hinge rod 321, a second drive handle 332, and a second hinge rod 322. The front ends of the first drive handle 331 and the second drive handle 332 are respectively hinged to the outer wall of the outer sheath 1, the two ends of the first hinge rod 321 are respectively hinged to the first drive handle 331 and the expander propulsion unit 31, and the two ends of the second hinge rod 322 are respectively hinged to the second drive handle 332 and the expander propulsion unit 31. Therefore, when the first drive handle 331 and the second drive handle 332 are manually pressed, the first drive handle 331 and the second drive handle 332 are closed radially inward, and the expander propulsion unit 31 is pushed forward relative to the outer sheath 1 via the first hinge rod 321 and the second hinge rod 322, respectively. Figure 2 The figure shows the expansion device propulsion unit 31 moving forward.

[0064] It can be understood that the first driving handle 331, the first hinge rod 321 and the second driving handle 332, the second hinge rod 322 are only an example of driving the expander propulsion unit 31 forward. Other driving methods can also be adopted, such as directly manually pushing the rear end of the expander propulsion unit 31 to move it forward, or only setting the first driving handle 331 and the first hinge rod 321 as a set of hinge transmission mechanisms. The present application sets two sets of hinge transmission mechanisms just to facilitate operation, but it is not a specific limitation.

[0065] Continue to view Figure 1 In the assembled state, the elastic expansion component 21 and the expander propulsion part 31 are at least partially located in the inner cavity of the outer sheath 1. The elastic expansion component 21 extends axially and is constrained by the front end inner wall of the outer sheath 1 and contracts radially, so that the front end of the elastic expansion component 21 is aggregated and is easier to insert into the foreskin opening.

[0066] During expansion operations, Figure 2 As shown, driven by external force, the expander propulsion portion 31 can push the expander 2 forward axially. After the elastic expansion component 21 reaches the predetermined position, it breaks away from the constraint of the outer sheath 1 and expands radially. At this time, the elastic expansion component 21 has at least partially penetrated into the foreskin opening, and the foreskin opening is stretched as the elastic expansion component 21 rebounds and expands.

[0067] See also Figure 3 The expander 2 further includes an expansion base 22. In this embodiment, the expansion base 22 is annular, and its shape is actually not limited, as long as it can fix the elastic expansion component 21. In this embodiment, the elastic expansion component 21 includes a plurality of elastic members distributed at intervals on the same side of the expansion base 22. More preferably, the plurality of elastic members are distributed at equal intervals along the circumference on the same side of the expansion base 22.

[0068] As a preferred method, Figure 3 Six elastic members are shown that are evenly spaced along the circumference. Each elastic member is made of metal and extends from the expansion base 22 to the same side in a broken line style. The front end of each elastic member away from the expansion base 22 has a certain curvature to facilitate penetration into the foreskin and reduce tissue damage.

[0069] It is understood that the number and structure of the elastic members in the elastic expansion assembly 21 are not specifically limited. It can be two elastic members symmetrically arranged in the radial direction, three elastic members arranged in a triangle, or more elastic members distributed at intervals, or it can be an integral elastic member arranged around the axis of the expansion base 22. As long as it can contract and expand in the radial direction, it will not be described here one by one. It is understood that the more elastic members in the present application, the more uniform the expansion force, the closer the foreskin opening is to a ring when it is stretched, the better the expansion effect, and the higher the user comfort.

[0070] During the expansion operation, the expander propulsion unit 31 pushes the elastic expansion component 21 forward in the axial direction via the expansion base 22. Figure 3 The side of the expansion base 22 away from the elastic expansion component 21 is provided with an axial groove 221 extending axially and a radial groove 222 extending circumferentially. The axial groove 221 and the radial groove 222 are connected to each other and both open toward the side away from the elastic expansion component 21. The radial groove 222 has a space for accommodating the plug bending portion 3112 described later on the side close to the elastic expansion component 21. As shown in the figure, the front inner wall of the radial groove 222 is in a step-like style to form a plug accommodating area 223.

[0071] In this embodiment, each axial groove 221 and radial groove 222 constitutes a groove group. A plurality of such groove groups can be arranged on the side of the expansion base 22 facing away from the elastic expansion component 21. The figure shows four equally spaced groove groups, but the specific number and distribution are not limited.

[0072] See also Figure 4The front end of the expander pusher 31 is provided with a pusher plug 311 corresponding to each groove group formed by the axial groove 221 and the radial groove 222. As an example, the pusher plug 311 is generally L-shaped, having an axially extending plug body 3111 and a plug bending portion 3112 bent from the front end of the plug body 3111 toward the radial inside.

[0073] During the assembly process, the expander 2 is installed into the inner cavity of the outer sheath 1 with the expansion base 22 facing backward, and the elastic expansion component 21 also at least partially enters the inner cavity of the outer sheath 1, and is then squeezed by the front inner wall of the outer sheath 1 and shrinks radially inward. The expander propulsion part 31 is installed into the inner cavity of the outer sheath 1 from the rear end, so that the propulsion part plug 311 is first inserted into the corresponding axial groove 221 on the expansion base 22, and then the expander propulsion part 31 or the expansion base 22 is rotated axially, so that the plug body 3111 enters the radial groove 222, and the plug bending part 3112 enters the plug accommodating area 223. Thereby, the expander propulsion part 31 and the expansion base 22 are mutually engaged.

[0074] After the expander 2 moves forward to the predetermined position, the expander propulsion unit 31 or the expander base 22 is rotated in the reverse direction to return the plug body 3111 and the plug bending portion 3112 to the axial groove 221, so that the expander 2 and the expander propulsion unit 31 can be easily separated.

[0075] It is understandable that the above-mentioned groove group and plug connection structure are only a preferred method, which can make the expansion base 22 and the expander propulsion part 31 connected firmly enough, so that the process of the expander 2 moving forward and entering the foreskin opening is more stable. Other connection methods can also be set, or only the expansion base 22 is abutted against the front end of the expander propulsion part 31, and the expander propulsion part 31 can also push the expansion base 22 forward and facilitate separation.

[0076] Support

[0077] Next, combine Figure 1 , Figure 2 and Figure 5 , Figure 6 The support member driving unit 5 will be described in detail. Figure 5 is a schematic diagram of the front end structure of the support member driving unit 5, Figure 6 It is a schematic structural diagram of the support member 4.

[0078] As mentioned above, the dilator 2 is used to stretch the foreskin and can stay in the foreskin for a period of time. However, during this period of stay, it may still cause certain discomfort to the user, especially when used for infants and young children. The dilator 2 is usually inserted during the day when the parents can watch over the child, but at night when the parents cannot watch over the child all the time, the dilator 2 is easy to fall off due to the infant's lack of cooperation.

[0079] To this end, the phimosis treatment device provided in the present application can provide another more comfortable and safer foreskin stretching retention device by integrating the support member and its driving unit in the inner cavity of the dilator propulsion part 31. Specifically, the support member driving unit 5 has a support member ejection part 51 and a support member propulsion part 52, and the dilator propulsion part 31 is provided with an inner cavity that penetrates along the axial direction. In the assembled state, the support member 4 is located on the radial inner side of the dilator 2, and the support member driving unit 5 is at least partially located in the inner cavity of the dilator propulsion part 31.

[0080] like Figure 1 As shown, as a preferred embodiment, the support member ejection portion 51, the support member propulsion portion 52 and the expander propulsion portion 31 are arranged in layers from the inside to the outside in the radial direction. As an example, the support member propulsion portion 52 is connected to the expander propulsion portion 31 via a threaded connection. The support member ejection portion 51 and the support member propulsion portion 52 are connected via a pin 53 extending in the radial direction, such as Figure 5 The support member pushing portion 52 has a pin groove 521 extending in the axial direction and opening toward the insertion end, and the pin groove 521 actually constitutes a front end notch of the support member pushing portion 52. In the assembled state, the pin 53 is inserted into the pin hole (not shown in the figure) of the support member ejection portion 51 and is located in the pin groove 521 of the support member pushing portion 52.

[0081] Therefore, when the external force rotates the support member ejection part 51 axially, the support member propulsion part 52 rotates synchronously under the drive of the pin 53. Since the support member propulsion part 52 and the expander propulsion part 31 are connected via threads, the support member propulsion part 52 moves forward relative to the expander propulsion part 31 when rotating. Then, the rear end groove wall of the pin groove 521 pushes the pin 53 forward, and the support member ejection part 51 is driven by the pin 53 to synchronously move forward along the axial direction relative to the expander propulsion part 31, and the support member 4 is pushed into the foreskin opening.

[0082] When the support member 4 is about to reach the predetermined position, the rotation of the support member ejection part 51 is stopped, and the support member ejection part 51 is pushed forward axially. The support member ejection part 51 pushes the support member 4 to the predetermined position and drives the pin 53 to move forward from the pin groove 521. At this time, the support member propulsion part 52 does not move axially, thereby separating the support member 4 from the support member propulsion part 52.

[0083] In other words, the support member propulsion portion 52 can rotate synchronously with the support member ejection portion 51, thereby driving the support member ejection portion 51 to move forward synchronously, and then the support member propulsion portion 52 remains stationary when the support member ejection portion 51 moves forward alone, so that the support member 4 can be easily separated from the support member propulsion portion 52. The setting of the threaded structure can also freely adjust the axial position of the support member propulsion portion 52 by rotation, which increases the operational flexibility.

[0084] In actual operation, the dilator 2 can be used alone for expansion, and dilators 2 of different specifications can be selected according to the size of the foreskin opening and the elasticity of some skin. At the same time, due to the small foreskin opening of infants and the difficulty in cooperation, it is difficult to place the support member 4. In this application, after the dilator 2 is placed and the foreskin opening is expanded, the support member 4 can be placed in the foreskin opening through the support member driving unit 5. After that, the dilator 2 is taken out, and only the support member 4 is retained in the foreskin opening as a replacement, which can achieve a certain expansion effect and increase the user's comfort.

[0085] like Figure 6 As shown, as a preferred embodiment, the support member 4 adopts a U-shaped design of a silicone ring. The silicone material is softer and skin-friendly. The overall shape of the U-shaped ring can be easily assembled with the support member drive unit 5, and the hollow channel can be easily put on the glans penis to achieve fixation and is not easy to fall off. The insertion end is designed with a frenulum avoidance port 41, which will not cause damage to the frenulum and reduce discomfort. The inner wall of the hollow channel of the support member 4 can be coated with drugs, or the drugs can be delivered to the hollow channel of the support member 4 through the support member drive unit 5, which can provide a better treatment effect. In addition, a urination hole is left in the middle of the support member 4, which does not affect normal urination after insertion.

[0086] The expander 2 and the support member 4 can be equipped with a variety of specifications, and the size can be gradually increased according to the actual situation. The expander 2 can be realized by adjusting the shape of the elastic expansion component 21, such as the bending angle and the diameter of the elastic expansion component 21, so that the outer sheath 1 does not need to be replaced. The support member 1 can be assembled at the front end of the support member driving unit 5, and the support member 4 can enter or not enter the inner cavity of the expander propulsion part 31, so that a support member driving unit 5 of one specification can be used to adapt to supports 4 of different specifications.

[0087] In addition, a flushing channel can be preset on the top of the dilator 2. After the dilator 2 is placed, the outside of the dilator 2 can be connected to a flusher for flushing or drug spraying, and the urethral opening can be avoided. No more details will be given here.

[0088] Elastic pin

[0089] Next, combine Figure 1 , Figure 2 The elastic pin will be described in detail.

[0090] See also Figure 1 , Figure 2 The outer peripheral wall of the outer sheath 1 is provided with a first pin hole 11, and a first elastic pin 61 having a specified deformation allowance in the radial direction is provided in the first pin hole 11. Meanwhile, the outer peripheral wall of the dilator propulsion part 31 has a plurality of first limiting grooves 610 spaced apart in the axial direction.

[0091] During the expansion operation, when the expander propulsion unit 31 moves axially under the action of external force, the first elastic pin 31 is first squeezed and deformed by the outer peripheral wall of the expander propulsion unit 31, and then rebounds and is inserted into one of the multiple first limiting grooves 610 to limit the axial movement of the expander propulsion unit 31; when the external force applied to the expander propulsion unit 31 reaches a predetermined value, it can overcome the limitation of the first elastic pin 61, so that the first elastic pin 61 is squeezed again and compressed radially, and disengaged from the limiting groove to release the limitation on the axial movement of the expander propulsion unit 31.

[0092] Furthermore, the outer peripheral wall of the outer sheath 1 is provided with a second pin hole 12, and a second elastic pin 62 having a specified deformation tolerance in the radial direction is provided in the second pin hole 12. The outer peripheral wall of the dilator propulsion part 31 has a plurality of second limiting grooves 620 spaced apart in the axial direction.

[0093] During the expansion operation, when the expander propulsion unit 31 moves axially under the action of external force, the second elastic pin 62 is first squeezed and deformed by the outer peripheral wall of the expander propulsion unit 31, and then rebounds and is inserted into one of the multiple second limiting grooves 620 to limit the axial movement of the expander propulsion unit 31; when the external force applied to the expander propulsion unit 31 reaches a predetermined value, it can overcome the limitation of the second elastic pin 62, so that the second elastic pin 62 is squeezed again and compressed radially, and disengaged from the limiting groove to release the limitation on the axial movement of the expander propulsion unit 31.

[0094] Among them, preferably, the first elastic pin 61 and the second elastic pin 62 are staggered in the axial direction in such a way that only one can be inserted into the corresponding limiting groove at a time. For example, the axial spacing between two adjacent limiting grooves in the plurality of first limiting grooves 610 and the plurality of second limiting grooves 620 is 2 mm, and the axial spacing between the first elastic pin 61 and the second elastic pin 62 is 1 mm. Then, when the first elastic pin 61 is inserted into the corresponding limiting groove, the second elastic pin 62 is in a state of being squeezed by the outer peripheral wall of the expander propulsion part 31 and not inserted into the corresponding limiting groove; when the first elastic pin 61 is disengaged from the corresponding limiting groove, the second elastic pin 62 enters the corresponding limiting groove. In this way, the step length of the axial limit during the advancement of the expander 2 can be shortened when the limiting groove is relatively fixed.

[0095] In summary, the phimosis treatment device of the present application can conveniently place the dilator 2 into the foreskin opening and separate it from the main body of the dilator. At the same time, the support member 4 can be conveniently placed into the foreskin opening and separated from the main body of the dilator according to the treatment needs of the user, thereby increasing the user's comfort. The drive unit of the dilator 2 and the drive unit of the support member 4 are integrated in a channel nesting manner, and flexible switching selection of functions is achieved with a smaller volume. Furthermore, the dilator 2 and the support member 4 are arranged on the front side of the outer sheath 1, and the dilator drive unit 3 and the support member drive unit 5 are arranged in the inner cavity of the outer sheath 1. The dilator 2 and the support member 4 can be set to different sizes and specifications for flexible disassembly, and the two sets of mechanisms are interconnected and compact in structure, which can achieve a better dilation effect and ensure convenient, simple and reliable operation, taking into account the safety, convenience and long-term versatility of phimosis treatment.
