Description

Technical Field

[0001] The utility model relates to the field of medical correction devices, and particularly relates to a nipple inversion correction device. Background Art

[0002] Nipple inversion means that the nipple fails to protrude sufficiently from the areola plane but is sunken inward into the areola, which not only affects the appearance but also brings troubles to lactation and breast health, seriously affecting the patient's lactation and causing breast inflammation, peculiar smell, etc. With the improvement of aesthetic concepts and the progress of medical technology, nipple inversion correction has increasingly become the focus of attention, aiming to restore the normal shape of the nipple and enhance the patient's self-confidence and quality of life.

[0003] Currently, nipple correction mostly uses a sleeve to cover the nipple, and a traction wire is passed through the bottom of the nipple and then fixed on the sleeve. By continuously applying force to the nipple through the traction wire, it is promoted to gradually return to its place and restore the normal shape. During the correction process, the patient needs to visit the hospital for a follow-up visit every week, and the medical staff tightens the traction wire to ensure the traction effect. The entire correction process lasts for several months. Frequent follow-up visits not only consume a lot of the patient's time, but also increase the workload of the medical staff, and may also bring economic pressure to the patient. Especially for patients far from the hospital, it is very inconvenient to travel back and forth. Content of the Utility Model

[0004] The utility model aims to provide a nipple inversion correction device to solve the problems that the current nipple correction device requires the patient to frequently go to the hospital to tighten the traction wire, resulting in inconvenience to the patient and a large workload for the medical staff.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A nipple inversion correction device includes a fixed cylinder and traction wires. The number of traction wires is two. Four wire passing holes are evenly arranged on the outer wall of the fixed cylinder. A rotating rod is arranged above the wire passing holes. The rotating rod is rotatably connected to the fixed cylinder. A fixing hole for fixing the traction wire is opened on the rotating rod. A plurality of card slots are evenly arranged on the rotating rod. A steel ball that can be inserted into the card slots is movably arranged on the fixed cylinder. A return spring is connected between the steel ball and the fixed cylinder. The depth of the card slot is less than the radius of the steel ball. The rotating rod is connected with a positioning member for positioning the rotating rod.

[0007] Preferably, as an improvement, the positioning member is a positioning sleeve. The positioning sleeve is threadedly connected to the rotating rod. An annular threaded hole is opened on the fixed cylinder outside the rotating rod. The positioning sleeve can be threadedly connected into the threaded hole.

[0008] Preferably, as an improvement, a wire collecting groove is arranged on the rotating rod.

[0009] Preferably, as an improvement, anti-slip lines are arranged on the positioning sleeve.

[0010] Preferably, as an improvement, an annular base is fixed to the bottom end of the fixing cylinder.

[0011] Preferably, as an improvement, a wear-resistant ring is provided on the inner wall of the wire passing hole.

[0012] The principle and beneficial effects of this solution are as follows:

[0013] 1. This solution facilitates the patient to tighten the traction wire by themselves. In actual use, it can be adjusted at home according to the doctor's advice, which can effectively extend the time for returning to the hospital for review, reduce the cost of the patient and the workload of medical staff, effectively improve the patient's compliance, and overcome the drawback that the existing correction device can only have the medical staff tighten the traction wire in the hospital. Specifically: In actual use, the two traction wires are crossed from the base of the nipple and then the two ends of the same traction wire are respectively fixed to the rotating rods on the opposite two wire guide grooves. Then, the positioning sleeve is screwed tightly into the fixing cylinder to fix the rotating rod, thereby fixing the traction wire. When adjustment is needed, the positioning sleeve is unscrewed, and the traction wire is tightened by rotating the rotating rod. When each rotating rod rotates to a card slot above the steel ball, the steel ball is snapped into the card slot under the action of the return spring. Continuing to apply force can squeeze the steel ball out of the card slot to continue rotating the rotating rod. By sensing the change in resistance after the steel ball is snapped in, the rotating rod can be rotated one grid at a time, which is convenient for controlling the tightening degree of the traction wire, ensuring that the two traction wires are evenly stressed, and the patient can also ensure the correction effect by self-adjustment.

[0014] 2. A wire winding groove is provided on the rotating rod of this solution to limit the traction wire, so that the traction wire is wound in the wire winding groove.

[0015] 3. Anti-slip lines are provided on the positioning sleeve to improve the operation stability and avoid slipping.

[0016] 4. An annular base is fixed to the bottom end of the fixing cylinder to increase the contact area with the breast, avoid stress concentration, thereby avoiding pressure sores and improving comfort.

[0017] 5. A wear-resistant ring is provided on the inner wall of the wire passing hole to improve the wear resistance of the wire passing hole and extend the service life of the fixing cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is further detailed through specific embodiments:

[0021] The reference numerals in the accompanying drawings of the specification include: fixed cylinder 1, wire passing hole 12, wear-resistant ring 13, traction wire 2, base 3, positioning sleeve 4, rotating rod 41, fixing hole 42, wire winding groove 43, card slot 44, steel ball 45, return spring 46, threaded hole 47.

[0022] Embodiment:

[0023] As Figure 1 and Figure 2 shown, a nipple inversion correction device includes a fixed cylinder 1 and a traction wire 2. A circular base 3 is integrally formed at the bottom end of the fixed cylinder 1. Four wire passing holes 12 are evenly formed in the outer wall of the fixed cylinder 1. A wear-resistant ring 13 is adhesively fixed on the inner wall of the wire passing hole 12. The wear-resistant ring 13 is made of a wear-resistant material in the prior art, such as rubber. Above the wire passing hole 12, there is a rotating rod 41. The rotating rod 41 is rotatably connected to the fixed cylinder 1. An annular wire winding groove 43 is formed in the rotating rod 41, and a fixing hole 42 for fixing the traction wire 2 is formed in the rotating rod 41. The number of traction wires 2 is two. In actual use, after the two traction wires 2 cross each other and pass through the nipple base, the two ends of the same traction wire 2 respectively pass out from two opposite wire passing holes 12 and are fixed on the rotating rod 41. A plurality of card slots 44 are evenly formed in the rotating rod 41. The number of card slots 44 can be set as required. In this embodiment, the number of card slots 44 is 10, and the distance between two adjacent card slots 44 is 2 mm. A steel ball 45 that can be inserted into the card slot 44 is movably arranged on the fixed cylinder 1. A return spring 46 is connected between the steel ball 45 and the fixed cylinder 1. The depth of the card slot 44 is less than the radius of the steel ball 45.

[0024] The rotating rod 41 is connected with a positioning member for positioning the rotating rod 41. The positioning member is a positioning sleeve 4. The positioning sleeve 4 is threadedly connected to the rotating rod 41. An annular threaded hole 47 is formed in the fixed cylinder 1 outside the rotating rod 41. The positioning sleeve 4 can be threadedly connected into the threaded hole 47. Anti-slip lines are engraved on the positioning sleeve 4.

[0025] In actual use, the two traction wires 2 cross each other and pass through the nipple base. The two ends of the traction wire 2 are located outside the skin. The fixed cylinder 1 is covered on the nipple. Then, after the two ends of the same traction wire 2 respectively pass out from two opposite wire passing holes 12 on the fixed cylinder 1 to the outside of the fixed cylinder 1, they are pulled to the rotating rod 41 above and pass through the fixing hole 42 on the rotating rod 41 and then tied into a knot to fix the traction wire 2 on the rotating rod 41. After fixing, the positioning sleeve 4 is screwed tightly into the threaded hole 47 on the fixed cylinder 1, thereby fixing the traction wire 2.

[0026] After the correction device of the present utility model is worn for the first time, the doctor issues medical advice to the patient, instructing the patient how often to tighten the traction wire 2 each time, how much to tighten each time, and how often to go to the hospital for a review. Specifically, when tightening the traction wire 2, first screw out the positioning sleeve 4 from the fixed cylinder 1. At this time, the rotating rod 41 can rotate. Then rotate the rotating rod 41. During the rotation process, every time a card slot 44 rotates above the steel ball 45, the steel ball 45 pops out under the action of the return spring 46 and snaps into the card slot 44, thereby rotating the rotating rod 41 by one grid. Due to the action of the steel ball 45 and the card slot 44, the resistance to rotating the rotating rod 41 becomes larger at this time, and more force is required to continue rotating the rotating rod 41 to squeeze the steel ball 45 out of the card slot 44. After the steel ball 45 is squeezed out, the resistance to rotating the rotating rod 41 becomes smaller, and at this time the rotating rod 41 rotates more easily. By clamping and positioning the rotating rod 41 through each card slot 44, the rotating rod 41 can be rotated one grid at a time. In actual use, medical staff can write in the medical advice how many grids to rotate each time when tightening. The patient can ensure that the rotation amplitudes of the four rotating rods 41 are the same according to the medical advice, thereby ensuring that the tightening degree of the end of the traction wire 2 is the same, ensuring balanced force on the nipple, so that the patient can tighten the traction wire 2 by himself without having to go to the hospital for medical staff to tighten each time.

[0027] The above are only embodiments of the present utility model. Specific technical solutions and / or common knowledge such as characteristics known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
