Description

Technical Field

[0001] The utility model belongs to the technical field of medical assistance, and in particular relates to a self-adhesive tissue compensation material. Background Art

[0002] Breast cancer is a phenomenon in which mammary epithelial cells proliferate uncontrollably under the influence of a variety of carcinogenic factors. In the early stages of the disease, symptoms such as breast lumps, nipple discharge, and enlarged axillary lymph nodes often occur. In the late stages, cancer cells may metastasize to distant sites, leading to multi-organ lesions that directly threaten the patient's life. Radical mastectomy is a common surgical treatment for breast cancer patients and is also the preferred treatment option for breast cancer patients. In the treatment of breast cancer, due to the dose-building effect of radiation, when the tumors of some patients invade the skin or are close to the skin, the skin dose will be insufficient and the cancer cells cannot be completely killed. Therefore, patients need to use tissue compensation during postoperative radiotherapy.

[0003] The patent with announcement number CN219071879U discloses a self-adhesive tissue compensator, which relates to the field of medical auxiliary technology, and includes two tissue compensators, each of which includes a hemispherical positioning membrane in the shape of a breast, and a hemispherical opening is opened on one side, the hemispherical positioning membrane is disconnected from the middle, and a retractable positioning belt that connects the disconnected hemispherical positioning membrane is fixedly connected, and the lower end of the disconnected side of the hemispherical positioning membrane is fixedly installed with a fixed plate, and an adjustment mechanism for adjusting the opening size of the retractable positioning belt is arranged between the two fixed plates. This technology adjusts the size of the positioning membrane by adjusting the tightening belt and the adhesive sheet in the adjustment mechanism. In addition, a plurality of notches are opened on the tightening belt, and a tightening rope runs through the plurality of notches. When the adhesive sheet slowly loses its stickiness due to contact, the adhesive sheet can be slowly locked by tightening the tightening rope.

[0004] During long-term use of the tissue compensator, the adhesive sheet in the adjustment mechanism will slowly lose its stickiness, and after the adhesive sheet loses its stickiness, it needs to be tightened with the tightening rope in the adjustment mechanism. Since the tightening rope has many turns when passing through the tightening belt when tightening, the friction between the tightening rope and the tightening belt is large, and it is not convenient to bring the relative adhesive sheets close to each other and lock them, resulting in the overall low practicality of the tissue compensator and the troublesome operation.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 7As shown, the technical solution adopted by the utility model is as follows: a self-adhesive tissue compensation material, including a positioning film 1, two positioning film pieces 1 form a hemispherical positioning film, and a retractable band 2 is fixedly arranged between the two positioning film pieces 1. The retractable band 2 and the positioning film 1 are a kind of thermoplastic film, specifically made of polymer elastic powder, liquid paraffin, and transparent polyethylene film, which can improve the elasticity of the hemispherical positioning film and the retractable band 2 during use. The retractable band 2 and the hemispherical positioning film are prepared by mixing, heating and curing, or by heating and curing any one of silicone and rubber. The retractable band 2 can be adjusted in width according to different forms of breasts.

[0028] The hemispherical positioning membrane is in the shape of a cover, and two hemispherical positioning membranes are fixedly provided. A bottom plate 16 is fixedly provided on one side of the two hemispherical positioning membranes away from the arc surface, and an adhesive plate 7 is slidably provided on the side of the hemispherical positioning membrane away from the arc surface; a hole is opened on the adhesive plate 7, and the hole is used for combining the breast and the hemispherical positioning membrane; the bottom plate 16 and the adhesive plate 7 are slidably matched.

[0029] A slider 18 is fixedly arranged on the top of the positioning film 1, and the slider 18 is fixedly connected to the bottom plate 16; a fixing block 14 is fixedly arranged on the top of the adhesive plate 7, and a groove 15 is opened at the bottom of the fixing block 14; the slider 18 is slidably connected to the groove 15, and the slider 18 can slide in the groove 15.

[0030] The sticking plate 7 is provided with a lifting and locking linkage mechanism for adjusting the size of the hemispherical positioning film. The lifting and locking linkage mechanism includes a card plate 3, which is fixedly connected to the sticking plate 7. A limiting groove 13 is provided on the card plate 3. The limiting groove 13 consists of a vertical groove and a horizontal groove. There are multiple horizontal grooves that are arranged parallel to each other, and one end of the multiple horizontal grooves is connected to the vertical groove. A push rod 4 is slidably arranged in the limiting groove 13.

[0031] A "V"-shaped limit block 5 is slidably arranged on one side of the adhesive plate 7 close to the card plate 3. A step groove 19 is provided on the limit block 5, and the step groove 19 close to the card plate 3 is a small groove. The push rod 4 is slidably connected with the step groove 19. The push rod 4 is provided with a chassis. The push rod 4 chassis slides in the large groove of the step groove 19, and the push rod 4 chassis is slidably connected with the adhesive plate 7, and the push rod 4 body slides in the small groove of the step groove 19. The step groove 19 is provided to prevent the push rod 4 from sliding out of the limit groove 13.

[0032] The bottom of the positioning film 1 is fixed with arc blocks 17, which are fixedly connected to the bottom plate 16. The lower ends of the opposite sides of the two arc blocks 17 are provided with arc surfaces. The two ends of the "V"-shaped limit block 5 are in conflict with the arc surfaces of the arc blocks 17.

[0033] By pulling the push rod 4 to move upward in the vertical groove, the limit block 5 is driven to move upward. When it moves to a suitable position, the push rod 4 only needs to slide into the horizontal groove on one side, and the limit block 5 will be limited by the horizontal groove in the limit groove 13. In addition, during the upward movement of the limit block 5, since the two ends of the limit block 5 are in contact with the arc surface of the arc block 17, the limit block 5 will generate a thrust to move toward the two arc blocks 17 during the upward movement, so that the arc block 17 pushes the two positioning film parts 1, so that the two positioning film parts 1 move toward each other, thereby squeezing the telescopic belt 2, and adjusting the hemispherical positioning film.

[0034] An elastic band 6 is fixedly arranged between the two adhesive plates 7 for adjusting the distance between the adhesive plates 7. A fixing band 8 is fixedly arranged at one end of the two adhesive plates 7 away from the elastic band 6, a Velcro 9 is fixedly arranged on one side of the fixing band 8, and a Velcro mother band 10 is fixedly arranged on the other side of the fixing band 8 for fastening the hemispherical positioning film.

[0035] A first adhesive sheet 11 is fixedly arranged inside the positioning film 1, and a second adhesive sheet 12 is fixedly arranged on the bottom plate 16. By tearing off the surface films on the first adhesive sheet 11 and the second adhesive sheet 12, the hemispherical positioning film is buckled on the breast to fit the skin and prevent slipping.

[0036] How it works

[0037] When the self-adhesive tissue compensator needs to be used, the Velcro sub-tape 9 and the Velcro mother-tape 10 are opened, the retractable belt 2 is stretched to a proper distance by external force, and then the self-adhesive tissue compensator is put on the patient.

[0038] When worn, the two hemispherical positioning membranes will slide along the width of the breast. When they slide to a comfortable position for the patient, the push rod 4 can be slid upward. The push rod 4 slides upward along the vertical groove to drive the limit block 5 to move upward. During the upward movement of the limit block 5, a thrust will be generated on the corresponding two arc blocks 17, prompting the two arc blocks 17 to push the corresponding two positioning membrane parts 1 inward. When moved to the appropriate position, just slide the push rod 4 to the horizontal groove on one side to limit the limit block 5, and then the two positioning membrane parts 1 will stop moving. It is more convenient for patients to adjust during use, and they can wear it directly for adjustment, avoiding discomfort caused to patients during use when the shape does not match.

[0039] After being adjusted to a suitable size, the surface films on the first adhesive sheet 11 and the second adhesive sheet 12 are torn off so that the hemispherical positioning film can be buckled onto the breast, thereby ensuring the breast skin dose during radiotherapy and effectively solving the problem that the breast-conserving therapy compensation material is difficult to apply.
