[0028] As shown in the figure, the utility model provides a clinical prostate expansion structure, including a spiral rod 1, a first expansion component 2 is provided on the spiral rod 1, a first sleeve 21 is provided on the first expansion component 2, a second sleeve 22 is provided at one end of the first sleeve 21, and an elastic film 23 is provided outside the first sleeve 21 and the second sleeve 22; the two ends of the elastic film 23 are respectively bonded to the two ends of the first sleeve 21 and the second sleeve 22. The first sleeve 21, the second sleeve 22, and the spiral rod 1 covered by the first sleeve 21 and the second sleeve 22 are all provided with air holes 4, and the spiral rod 1 is provided with a fifth circular hole 5, and the depth of the fifth circular hole 5 is the distance from one end of the spiral rod 1 to one end of the first sleeve 21.

[0029] Gas is introduced into the spiral rod 1 through the fifth circular hole 5, and the gas passes through the air holes 4 on the spiral rod 1, the first sleeve 21 and the second sleeve 22, gradually expanding the elastic membrane 23 until it expands to a required size. The elastic membrane 23 expands the prostate to improve the user's comfort.

[0030] The second expansion component 3 is disposed on the periphery of the first expansion component 2, and a first fixing plate 31 is disposed on the second expansion component 3. A plurality of first grooves 32 are evenly disposed on the first fixing plate 31. First round holes 33 and second round holes 34 are disposed on both sides of the first groove 32, respectively, on the first fixing plate 31. A second fixing plate 35 is also disposed on the second expansion component 3, and a second groove 36 is disposed on the second fixing plate 35. The first fixing plate 31 and the second fixing plate 35 are connected by a plurality of supporting units 39. When the first fixing plate 31 is in a fixed state, the supporting units 39 can be changed into different states by adjusting the second fixing plate 35.

[0031] A first support rod 391 is provided on the support unit 39, a first connecting plate 392 is provided at one end of the first support rod 391, a second support rod 393 is provided on one side of the first connecting plate 392, a first pillar 394 is provided at the other end of the first support rod 392 and vertically connected thereto, and a second pillar 395 is provided at one end of the second support rod 393 and vertically connected thereto.

[0032] A third groove 12 and a fourth groove 13 are respectively provided at both ends of the first connecting plate 392, a sixth circular hole 14 and a seventh circular hole 15 are respectively provided on both sides of the third groove 12, and an eighth circular hole 16 and a ninth circular hole 17 are respectively provided on both sides of the first connecting plate 392.

[0033] The first support rod 391 is arranged at the first groove 32, and the two ends of the first pillar 394 are respectively arranged in the first circular hole 33 and the second circular hole 34; the second support rod 393 is arranged at the second groove 36, and the two ends of the second pillar 395 are respectively arranged in the third circular hole 37 and the fourth circular hole 38.

[0034] The structural design of the support unit 39 can flexibly change its own state.

[0035] The reason for providing the first groove 32 and the second groove 36 at the first fixing plate 31 and the second fixing plate 35 respectively is that if protrusions are provided, the nerves at the urethra, bladder and prostate are relatively sensitive. After the clinical expansion structure of the prostate enters these places, the protrusions will aggravate the stimulation to the surfaces of these places, causing the patient to feel great discomfort and may even struggle. Therefore, the first groove 32 and the second groove 36 are provided to reduce the stimulation and reduce the patient's discomfort.

[0036] One side of the first fixing plate 31 is connected to one end of the spiral rod 1, and the other side of the first fixing plate 31 is provided with a probe 6. The probe 6 can detect the inner conditions of the prostate clinical expansion structure after it enters the urethra, gradually enters the bladder and the prostate, and the surface of the probe 6 is relatively smooth, so the user's pain can be reduced when the probe 6 initially enters the urethra and gradually goes deeper.

[0037] The second fixing plate 35 is provided with a through hole 7. The second fixing plate 35 is sleeved on the spiral rod 1 at one end of the second sleeve 22. A snap ring 8 is provided on the other side of the second fixing plate 35 to be fixedly connected thereto. A third sleeve 9 is sleeved on the snap ring 8. A fourth sleeve 10 is provided on the other end of the third sleeve 9 to be fixedly connected thereto. An auxiliary rotating head 11 is provided on the other end of the fourth sleeve 10 to help the user not to slip during rotation. The inner sides of the fourth sleeve 10 and the auxiliary rotating head 11 are provided with threads that match the threads on the spiral rod 1. The auxiliary rotating head 11 can be rotated to rotate the fourth sleeve 10 and the third sleeve 9. At the same time, the snap ring 8 and the second fixing plate 35 are moved in the direction of the second sleeve 22, and the support unit 39 is expanded. Due to the arrangement of the first sleeve 21 and the second sleeve 22, the distance that the snap ring 8 and the second fixing plate 35 can move is limited, which prevents the support unit 39 from expanding too much.

[0038] Working principle: When in use, rotate the auxiliary rotating head 11, the third sleeve 9 and the fourth sleeve 10 rotate and move, the retaining ring 8 and the second fixed plate 35 move, so that the support unit 4 expands to a certain range, and then gas is introduced into the spiral rod 1 through the fifth circular hole 5. After the elastic membrane 23 expands, rotate the auxiliary rotating head 11 again, and the expansion range of the support unit 39 decreases until the expansion diameter requirement is met and the patient is in a more comfortable state. At this time, only the expanded elastic membrane 23 is completing the expansion.

[0039] Therefore, the utility model adopts the above-mentioned prostate clinical expansion structure, which can not only observe the situation of entering the prostate but also reduce the discomfort of the user.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
