Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical rehabilitation equipment, in particular to a compression fixing device for postoperative rehabilitation of breast cancer. BACKGROUND

[0002] Breast cancer is one of the most common malignant tumors in women, and surgical treatment is the main treatment method, including mastectomy, breast-conserving surgery and axillary lymph node dissection. During the wound healing process after surgery, complications such as subcutaneous hydrops, hematoma and skin flap necrosis are prone to occur. The incidence of subcutaneous hydrops after axillary lymph node dissection is relatively high, which seriously affects the rehabilitation process of patients. Compression fixation, as a key link of postoperative nursing, aims to promote the close adhesion of skin flaps and chest wall tissue through external moderate pressure, reduce bleeding and exudation of the wound, and reduce the risk of complications. At the same time, it needs to provide a stable environment for wound healing to avoid skin flap displacement caused by limb movement. In addition, there are different needs for compression force at different rehabilitation stages - mild compression is needed in the early postoperative period to prevent bleeding, and moderate compression is needed in the recovery period to promote the absorption of hydrops, which puts forward clear requirements for the pressure adjustment ability of the compression fixing device.

[0003] The current clinical and market postoperative compression fixing products for breast cancer mainly include traditional elastic bandages, 8-shaped bandages, special compression chest bands and axillary compression bandages. Although the traditional elastic bandage is soft and low in price, it has obvious defects: first, the pressure uniformity is poor and cannot be accurately adjusted, which is easy to cause over-tightening to affect blood circulation or over-looseness to cause compression failure, and some patients also have skin problems due to material allergy; second, it lacks upper limb restraint function, and the uncontrolled movement of the affected upper limb after surgery easily leads to skin flap displacement, increasing the risk of subcutaneous hydrops. The 8-shaped bandage needs to be used with an axillary pad, but its elasticity is poor and the fixation is unstable, and the doctor needs to operate for more than 20 minutes with two people, and cannot consider the synchronous compression of the breast and axilla, and needs to be completely disassembled and re-wrapped for postoperative adjustment, which is extremely inconvenient. The existing special compression chest bands, such as the breast compression elastic bandage produced by Di Furen, can realize local compression of the breast or axilla, but generally have the problem of insufficient adaptability, such as size deviation leading to edge lifting, lack of consideration for different surgical resection ranges and breast residual volume, and inability to realize dynamic adaptation from early postoperative anti-hemorrhage to recovery period to promote hydrops absorption, which restricts the postoperative rehabilitation effect. SUMMARY

[0004] To solve the above problems, the present application provides a compression fixing device for postoperative rehabilitation of breast cancer, which realizes precise postoperative rehabilitation compression of breast cancer through differential pressure adjustment, upper limb restraint cooperation and individual adaptation optimization.

[0005] In order to achieve the above object, the technical scheme of the present application is as follows: A compression fixing device for breast cancer postoperative rehabilitation, comprising a main belt body for surrounding the chest and / or back of a patient, the main belt body comprising a healthy area and a sick side area located at a position corresponding to a surgical area, the sick side area being provided with a compression assembly near the middle part, and symmetrical shoulder straps being provided at the top of the main belt body, the shoulder strap located at one side of the sick side area being provided with a restraint assembly for restraining the lifting action of the upper limbs of the patient;

[0006] The compression assembly comprises a base layer located inside the main belt body and close to the skin side, and a plurality of adjusting petals arranged along the axial direction of the base layer; the bottom and top of the main belt body are respectively provided with a second movable cavity and a first movable cavity, the first movable cavity and the second movable cavity are respectively provided with a first pulling assembly and a second pulling assembly, the top and bottom of the adjusting petals are respectively fixedly connected with the first pulling assembly and the second pulling assembly, and the top of the first pulling assembly is fixedly connected with the restraint assembly.

[0007] The first pulling assembly and the second pulling assembly are both used to drive the adjusting petals to move based on the body shape and posture of the patient to reduce the compression on the surgical area of the patient, and the sick side area is further provided with an adjusting assembly, the two sides of the adjusting assembly are respectively fixedly connected with the first pulling assembly and the second pulling assembly, the adjusting assembly comprises a fixed strip, one side of the fixed strip is provided with a pulling strip, the pulling strip penetrates through the main belt body and extends to the outside, an elastic rope is arranged on the pulling strip, and a plurality of adjusting blocks are equidistantly arranged on the underarm of the patient at one side of the surgical area of the patient on the outer side wall of the main belt body.

[0008] The technical principle of the above scheme is as follows:

[0009] The pressure dynamic adjustment is realized through the adjusting assembly of the sick side area of the main belt body, which adapts to the differentiated needs of early postoperative bleeding prevention and recovery period liquid absorption promotion; at the same time, the restraint assembly of the shoulder strap and the first pulling assembly of the compression assembly are linked, when the upper limbs of the patient on the sick side are unconsciously lifted, the restraint assembly pulls the first pulling assembly, the arm part is tightened to remind braking, and the premature activity of the upper arm is avoided to cause subcutaneous hydrops, and the surgical area is not severely compressed.

[0010] The above scheme has the following beneficial effects:

[0011] 1、The pulling strip can drive the first pulling assembly and the second pulling assembly to adjust the moving state of the adjusting petals, and in combination with the limiting of the adjusting blocks corresponding to the early postoperative bleeding prevention and the recovery period liquid absorption promotion, the surgical area compression strength can be accurately controlled, the rehabilitation is avoided to be affected by improper compression, early bleeding is prevented, and late liquid absorption is promoted.

[0012] 2、The constraint assembly is fixedly connected with the first pulling assembly. When the patient tries to lift the upper arm (postoperative contraindicated action), the constraint assembly will be first pulled tight, and the force is then transmitted through the first pulling assembly, mainly causing the tightening of the device in the armpit and the upper arm root area, producing a direct restraint and reminding, rather than converting all the pulling force into vertical pressure on the surgical incision. This not only achieves the purpose of limiting improper activities, but also protects the surgical area from accidental pulling or excessive compression, in line with the psychological and physiological bearing capacity of the patient.

[0013] 3、The main band body changes the fitting relationship with the skin when the patient takes a deep breath, expands the chest, or changes posture, and the first pulling assembly and the second pulling assembly can drive the adjusting flaps to fold or open slightly, redistributing the pressure and avoiding the formation of uncomfortable compression points at the intercostal or scar protrusions, improving the comfort and safety of long-term wear.

[0014] Further, the main band body further comprises a fixing band and an adjusting band, both of which are located at the lower part of the main band body close to the patient's chest side segment, and both the fixing band and the adjusting band are provided with an arc-shaped memory keel that can adaptively deform according to the patient's chest contour and maintain a fitting state. The main band body is provided with an adjusting buckle at the patient's back, which is used to adjust the gap between the fixing band and the adjusting band.

[0015] Beneficial effects: The memory keel can automatically bend to fit the patient's unique chest contour, providing uniform base support and avoiding the upper and lower edges of traditional bandages from being raised or unevenly compressed due to fixed shape. Combined with the adjusting buckle, the patient can easily adjust the overall tightness of the main band body, ensuring that the device is stable and does not slide down while adapting to possible postoperative changes in chest circumference, such as swelling subsiding, achieving individualized initial adaptation.

[0016] Further, the adjusting buckle comprises a sliding block and a sliding rail that slide relative to each other, and the sliding block is provided with a locking knob. The overall circumference of the main band body is adjusted by moving the sliding block horizontally along the sliding rail.

[0017] Beneficial effects: The overall circumference of the main band body can be adjusted by moving the sliding block horizontally along the sliding rail, which is intuitive and convenient to operate. The locking knob can fix the position of the sliding block after adjusting to the appropriate circumference, preventing the device from loosening during wear and ensuring the stability of the compression force and the restraint effect.

[0018] Further, the elastic connecting pieces are buckle-connected between adjacent adjusting flaps to adapt to different surgical resection ranges and residual breast volumes.

[0019] Beneficial effects: The elastic connecting pieces have scalability, which can flexibly adapt to the range of resected breast tissue and the residual breast volume after surgery, avoiding local compression discomfort caused by the hard connection between the adjusting flaps, and improving the adaptation ability of the device to different individual surgical conditions.

[0020] Further, the first pulling assembly and the second pulling assembly respectively include a first pulling strip and a second pulling strip, the inner side wall of the adjusting petal is provided with symmetrical rigid support strips, the rigid support strips extend to the top and the bottom of the adjusting petal, and the first movable cavity and the second movable cavity are respectively provided with a first connecting cloth and a second connecting cloth, the first connecting cloth and the second connecting cloth are both two cloth strips provided with through channels, and the cloth strips of the first connecting cloth and the second connecting cloth are respectively fixedly connected with the two ends of the rigid support strips.

[0021] Beneficial effects: The connecting cloth increases the contact area of the first pulling strip and the second pulling strip at the connection position of the adjusting petal, so that the force transmission is more uniform, and local stress concentration is avoided to cause damage of the adjusting petal or discomfort of the patient; the fixed connection of the pulling strip and the fixed strip ensures that the adjusting effect of the adjusting assembly on the compression assembly can be stably transmitted, and the reliability of pressure adjustment is improved. The rigid support strip enhances the structural strength of the connecting cloth, avoids deformation of the connecting cloth during pulling to affect power transmission, drives the adjusting petal to be precisely folded or expanded along the radial direction through the first pulling strip and the second pulling strip, realizes fine adjustment of compression force, and improves the accuracy of pressure control.

[0022] Further, the first connecting cloth is slidably connected with first and second pulling ropes in opposite directions, the left end of the first pulling rope is fixedly connected with the first pulling strip, the first movable cavity is provided with a first partition layer, and the right end of the second pulling rope penetrates through the first partition layer and is fixedly connected with the first pulling strip located on the left side of the affected side area; the second connecting cloth is slidably connected with third and fourth pulling ropes in opposite directions, the second movable cavity is provided with a second partition layer, the left end of the third pulling rope is fixedly connected with the second pulling strip, and the right end of the fourth pulling rope penetrates through the second partition layer and is fixedly connected with the second pulling strip.

[0023] Beneficial effects: The first / second pulling rope or the third / fourth pulling rope is connected to the first pulling strip or the second pulling strip in opposite directions, when the first pulling strip or the second pulling strip is pulled in the same direction, the two pulling ropes in opposite directions can be simultaneously tightened in one direction, realizing rapid and symmetrical tightening of the connecting cloth on one side. The existence of the first partition layer and the second partition layer enables the first / second pulling rope or the third / fourth pulling rope to be pulled at both ends simultaneously when the same force is applied, and avoids the first / second pulling rope or the third / fourth pulling rope from being intertwined and knotted in the first movable cavity or the second movable cavity.

[0024] Further, the restraint assembly includes a plurality of traction belts, one end of each of the traction belts is fixedly connected in the shoulder strap, and the other end of each of the traction belts is fixedly connected to one side of the first pulling strip.

[0025] Beneficial effects: The plurality of traction belts can pull the first pulling strip from multiple angles of the shoulder strap, so that the force transmission is more balanced when the upper limb is lifted, local discomfort or adjusting deviation of the adjusting petal caused by a single traction point is avoided, and the stability and effectiveness of the upper limb restraint are enhanced.

[0026] Further, the traction belt is an elastic binding belt with adjustable length, and the part of the traction belt in contact with the upper arm of the affected side is provided with a plurality of pads.

[0027] Beneficial effects: the adjustable length design can adapt to the upper arm size of different patients, ensuring moderate restraint force; the elastic material allows a certain amount of activity while restraining, improving wearing comfort; the pads can reduce friction between the traction belt and the skin of the affected upper arm, avoid skin damage, and enhance the tolerance of long-term wearing.

[0028] Further, the adjusting block is provided with scale marks corresponding to the mild area for preventing bleeding in the early postoperative period and the moderate area for promoting fluid absorption in the recovery period, respectively.

[0029] Beneficial effects: the scale marks enable medical staff and patients to quickly identify and adjust the compression force to the corresponding rehabilitation stage without relying on experience, improving the convenience and accuracy of pressure adjustment, and ensuring that the rehabilitation needs of each stage are accurately met.

[0030] Further, the base layer and the shoulder strap are made of medical-grade elastic fiber material that is breathable and anti-allergic.

[0031] Beneficial effects: the breathable material can promote skin blood circulation and reduce skin discomfort caused by sweat accumulation; the anti-allergic property reduces the risk of allergic reactions in sensitive skin after surgery, improves the biocompatibility and wearing safety of the device, and is suitable for long-term wearing by patients.

[0041] The specific embodiments will be described in detail below:

[0042] Embodiment:

[0043] In the rehabilitation after breast cancer surgery, effective local compression is essential to prevent bleeding, promote skin flap adhesion and drain effusion. However, the existing postoperative compression bandage or fixing band widely used in clinical practice has significant defects: first, most of these products are designed with uniform or limited sizes, which cannot accurately fit the individualized chest shape, surgical resection range and residual breast volume of patients, and are prone to uneven compression, resulting in effusion cavity in the concave part and excessive compression in the convex part.

[0044] Therefore, the inventors propose a compression fixing device for postoperative rehabilitation of breast cancer as shown in the accompanying drawings. Figure 1 The compression fixing device for postoperative rehabilitation of breast cancer comprises a main band body 2 for wrapping around the chest and / or back of the patient, the main band body 2 comprising a healthy area 15 and a diseased area 14 located at the corresponding position of the surgical area, the diseased area 14 being provided with a compression assembly near the middle part, and symmetrical shoulder straps 1 being provided at the top of the main band body 2, one of the shoulder straps 1 located at the side of the diseased area 14 being provided with a restraint assembly for restricting the lifting action of the upper limbs of the patient.

[0045] The compression assembly comprises a base layer and a plurality of adjusting petals 12, the base layer being located inside the main band body 2 and close to the skin side, and the base layer and the shoulder straps 1 being made of medical-grade elastic fiber material with air permeability and anti-allergy.

[0046] The adjusting petals 12 are arranged along the axial direction of the base layer; the bottom and top of the main band body 2 are respectively provided with a second movable cavity 10 and a first movable cavity 21, the first movable cavity 21 and the second movable cavity 10 are respectively provided with a first pulling assembly and a second pulling assembly, the top and bottom of the adjusting petals 12 are respectively fixedly connected with the first pulling assembly and the second pulling assembly, and the top of the first pulling assembly is fixedly connected with the restraint assembly; the first pulling assembly and the second pulling assembly are used to drive the adjusting petals 12 to move based on the body shape and posture of the patient to reduce the compression on the surgical area of the patient, and the side of the diseased area 14 is provided with an adjusting assembly, the two sides of the adjusting assembly are respectively fixedly connected with the first pulling assembly and the second pulling assembly, the adjusting assembly comprises a fixed strip 8, one side of the fixed strip 8 is provided with a pulling strip 4, the pulling strip 4 penetrates through the main band body 2 and extends to the outside, the pulling strip 4 is provided with an elastic rope 5, a plurality of adjusting blocks 3 are equidistantly arranged on the lateral wall of the main band body 2 at the armpit of the patient on the side of the surgical area, and the adjusting blocks 3 are all provided with grooves for suspending the elastic rope 5; the adjusting blocks 3 are respectively provided with scale marks corresponding to the mild area for preventing bleeding in the early postoperative period and the moderate area for promoting effusion absorption in the recovery period, as shown in the accompanying drawings, the mild area is the adjusting block 3 close to the upper and lower sides of the elastic rope 5, and the moderate area is the adjusting block 3 away from the upper and lower sides of the elastic rope. Figure 1

[0047] The first pulling assembly and the second pulling assembly respectively comprise a first pulling strip 16 and a second pulling strip 9, and the inner lateral wall of the adjusting petals 12 is provided with symmetrical rigid support strips 20, as shown in the accompanying drawings. Figure 5 ​As shown, the rigid support strip 20 extends to the top and bottom of the adjusting petals 12, and the first movable cavity 21 and the second movable cavity 10 are respectively provided with a first connecting cloth 22 and a second connecting cloth 11, both of which are two cloth strips with through passages, and the cloth strips of the first connecting cloth 22 and the second connecting cloth 11 are respectively fixedly connected with the two ends of the rigid support strip 20; the first connecting cloth 22 is slidably connected with a first pulling rope 23 and a second pulling rope 24 in opposite directions, as shown in Figure 3 As shown, the left end of the first pulling rope 23 is fixedly connected with the first pulling strip 16, the first movable cavity 21 is provided with a first partition layer 25, the right end of the second pulling rope 24 penetrates through the first partition layer 25 and is fixedly connected with the first pulling strip 16 located on the left side of the affected side area; similarly, the second connecting cloth 11 is slidably connected with a third pulling rope 26 and a fourth pulling rope 27 in opposite directions, the second movable cavity 10 is provided with a second partition layer 28, the left end of the third pulling rope 26 is fixedly connected with the second pulling strip 9, and the right end of the fourth pulling rope 27 penetrates through the second partition layer 28 and is fixedly connected with the second pulling strip 9.

[0048] The main band body 2 further comprises a fixing band 17 and an adjusting band 18, both of which are located at the lower part of the main band body 2 close to the patient's chest side segment, and both the fixing band 17 and the adjusting band 18 are provided with an arc-shaped memory keel made of medical-grade shape memory alloy or high-molecular composite material with elastic memory function, which has a long strip-shaped arc-shaped support strip and a flat or oval cross-section, and is embedded along the inner side of the fixing band 17 and the adjusting band 18, and is pre-formed into an arc shape along the natural curvature of the human thoracic cavity. Since the memory keel has a certain initial curvature, it is suitable for the average curvature of the human thoracic cavity, and at the same time, the material has flexibility and elastic memory characteristics, which can bend and deform within a certain range and return to its original state after the external force is removed. Therefore, when the patient wears the device, the memory keel is slightly compressed by the actual curvature of the thoracic cavity, and the curvature is completely fitted to the individual thoracic cavity of the patient. Because the material has shape memory characteristics, the memory keel will not completely rebound after deformation, but will remain in the adapted arc state, thereby realizing personalized fitting.

[0049] The main band body 2 is provided with an adjusting buckle 19 at the patient's back, which is used to adjust the gap between the fixing band 17 and the adjusting band 18. The adjusting buckle 19 comprises a sliding block and a sliding rail that slide relative to each other, and a locking knob is arranged on the sliding block. The overall circumference of the main band body 2 is adjusted by moving the sliding block along the sliding rail, and the adjacent adjusting petals 12 are connected by elastic connecting pieces 13 to adapt to different surgical resection ranges and breast residual volumes.

[0050] The restraint assembly includes several traction straps. One end of each traction strap is fixedly connected to the shoulder strap 1, and the other end of each traction strap is fixedly connected to one side of the first pull bar 16. Each traction strap is an adjustable-length elastic restraint strap 7, and the part of the traction strap that contacts the affected upper arm is provided with several pads 6.

[0051] The following example uses a patient who underwent a modified radical mastectomy for right-sided breast cancer with axillary lymph node dissection. Specifically, on the first postoperative day, medical staff fitted the patient with this compression fixation device. First, the main strap 2 is wrapped around the patient's chest and back, with the affected side area 14 of the main strap 2 corresponding to the surgical area. The lower fixing strap 17 and adjusting strap 18 of the main strap 2 contain an arc-shaped memory rib. After contacting the patient's ribcage, the memory rib adapts to the curvature of the ribcage, quickly and tightly fitting the patient's ribcage to ensure the stability of the main strap 2. Next, medical staff adjust the overall circumference of the main strap 2 using the adjusting buckle 19 on the back of the main strap 2. The adjusting buckle 19 includes a slider and a slide rail that slide together. Medical staff push the slider laterally along the slide rail until the circumference of the main strap 2 is suitable, and then tighten the locking knob to fix the slider position, so that the main strap 2 is neither too loose to cause displacement nor too tight to affect the patient's breathing.

[0052] Subsequently, to address the need for mild compression in the early postoperative period to prevent bleeding, medical staff operated the adjustment components on the affected side 14. The adjustment components include a fixing bar 8 and a drag bar 4. The drag bar 4 extends through the main band 2 to the outside and is equipped with an elastic cord 5. Several adjustment blocks 3 are symmetrically located on the outer side of the main band 2 under the armpit. Each adjustment block 3 has markings corresponding to the mild postoperative area and the moderate recovery area. Medical staff suspended the elastic cord 5 on the drag bar 4 at the mild area marking on the adjustment block 3. At this time, the elastic cord 5 exerted a certain pulling force on the drag bar 4, causing the drag bar 4 to drive the first and second pulling components fixedly connected to it. Because the first and second pulling components respectively include a first pulling bar 16 and a second pulling bar 9, and their ends away from the adjustment flap 12 are fixedly connected to the fixing bar 8, when the first pulling bar 16 is pulled to the left (towards...), Figure 3 Taking the direction as an example, the first pull bar 16 simultaneously drives the first drawstring 23 and the second drawstring 24 to pull to the left. Since the second drawstring 24 is set through the first partition 25, when the second drawstring 24 is pulled to the left, the actual force direction is the right end. Therefore, the first drawstring 23 and the second drawstring 24 can simultaneously achieve the purpose of tightening the first connecting cloth 22. Therefore, the first connecting cloth 22 drives the several adjusting valves 12 arranged axially along the rigid support bar 20 to converge towards the middle area of ​​the patient. The second pull bar 9 works in the same way. Therefore, when the adjusting valves 12 converge, a slight pressure is formed on the surgical area of ​​the patient. The pressure is just enough to prevent bleeding in the surgical area without affecting local blood circulation.

[0053] Meanwhile, the restraint assembly on the side of the shoulder strap 1 in the affected area 14 begins to work. The restraint assembly includes several traction belts, one end of which is fixed in the shoulder strap 1, the other end is fixed on one side of the first pulling bar 16, and the adjustable length elastic binding belt 7 is provided with a pad 6 in contact with the upper arm of the affected side. The medical staff adjusts the length of the traction belt according to the size of the patient's upper arm, so that the traction belt gently binds the patient's upper arm on the affected side. When the patient unconsciously wants to lift the upper arm on the affected side due to discomfort, the upper arm will generate a pulling force on the traction belt, which will drive the first pulling bar 16 to tighten further, and the first pulling bar 16 will drive the first connecting cloth 22 through the first and second pulling ropes 23 and 24 to drive the adjusting flap 12 to further close, and at the same time, the elastic binding force of the traction belt itself will also be enhanced, tightening the patient's arm, which will remind the patient not to lift the arm, thereby effectively restraining the lifting action of the upper limb on the affected side, avoiding the subcutaneous hydrops caused by early activity. The setting of the pad 6 improves the comfort of the patient when wearing, preventing the traction belt from causing pressure damage to the skin.

[0054] On the fourth day after the operation, the risk of bleeding in the patient's operation area is reduced, and the patient enters the recovery period and needs moderate pressure to promote the absorption of hydrops. The medical staff only needs to remove the elastic rope 5 on the pulling bar 4 in the adjusting assembly from the light area scale of the adjusting block 3 and rehang it at the moderate area scale. After the elastic rope 5 is hung at a different position, the pulling force on the pulling bar 4 increases, and further drives the first and second pulling bars 16 and 9 through the fixed bar 8 to generate greater pulling force, which is transmitted to the rigid support bar 20 through the first and second pulling ropes 23 and 24, and the third and fourth pulling ropes 26 and 27, so that the adjusting flap 12 is further closed along the radial direction, and the pressure on the patient's operation area is increased to a moderate range. This moderate pressure can promote the diffusion and absorption of subcutaneous hydrops in the operation area to the surrounding tissue, and speed up the patient's recovery process.

[0055] At this stage, the restraint assembly still continues to work. When the patient tries to lift the arm, the linkage mechanism of the traction belt and the first pulling bar 16 will still remind and restrain in time to ensure that the patient will not affect the absorption of hydrops due to the early activity of the upper limb during the recovery period. At the same time, the elastic connecting piece 13 connected by buckling between the adjacent adjusting flaps 12 on the main belt body 2 begins to show its adaptive advantage. Since the residual volume of the patient's breast may change due to factors such as detumescence during the recovery process, the elastic connecting piece 13 can stretch according to the change of the residual volume of the breast, keep the adjusting flap 12 closely fitted with the patient's operation area, and ensure the stability of the compression effect. At the same time, when the patient needs to relax the operation area, the elastic rope 5 is removed from the adjusting block 3, and after losing the pulling force, the elastic connecting piece 13 reversely pushes the adjusting flap 12 to reset, allowing the patient to relax the restraint of the affected area appropriately. The memory keel also continuously maintains the fitting state with the patient's chest, ensuring that the entire device will not be displaced during the patient's activity.

[0056] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
