Description

Technical Field

[0001] This invention specifically relates to a device for preventing wound rupture during upper limb exercise after breast surgery. Background Technology

[0002] Breast cancer is a condition in which breast epithelial cells proliferate uncontrollably under the influence of various carcinogenic factors. Early symptoms often include breast lumps, nipple discharge, and enlarged axillary lymph nodes. In later stages, distant metastasis of cancer cells can lead to multi-organ complications, directly threatening the patient's life.

[0003] Surgery is one of the main treatment methods for breast cancer. Breast cancer patients are prone to upper limb movement disorders after surgery. Additionally, lymphatic drainage is often obstructed due to axillary lymph node dissection, leading to upper limb edema. Therefore, postoperative upper limb functional exercises are particularly important. Exercises should begin early postoperatively; waiting until surgical scars have formed reduces their effectiveness. However, when patients perform arm-raising exercises early postoperatively, the upward movement of the arm pulls on the wound skin. Since the wound is not fully healed in the early postoperative period, this can easily cause wound dehiscence, making upper limb exercises inconvenient and increasing the risk of infection. Therefore, to address these technical problems, a wound dehiscence prevention device for upper limb exercises after breast cancer surgery is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a wound rupture prevention device for upper limb exercises after breast surgery, which avoids pulling on the wound skin during upper limb exercises and prevents wound rupture, while also facilitating upper limb exercises.

[0005] A device for preventing wound rupture during upper limb exercise after breast surgery, comprising:

[0006] The fixation base can be secured to the patient's skin;

[0007] A driving component is slidably disposed on the fixed base along the height direction of the fixed base, and the driving component can slide upward when the patient raises his arm;

[0008] The first protective component includes a first pressure rod, which is slidably disposed on the fixed base along the height direction of the fixed base and located below the driving member;

[0009] The second protective component includes two sets of second pressure rods, which are slidably disposed on the fixed base along its length and located below the first pressure rod. One side of both the first and second pressure rods is designed to conform to the skin surrounding the patient's wound.

[0010] A transmission mechanism is mounted on the fixed base and is connected to the driving member, the first pressure rod, and the two sets of second pressure rods respectively, so that when the patient raises his arm, the sliding of the driving member is converted into the movement of the first pressure rod and the two sets of second pressure rods toward closing the wound.

[0011] The beneficial effects of the above-mentioned upper limb exercise wound rupture prevention device after breast surgery are as follows:

[0012] By fixing the fixation base to the patient's skin and positioning the first pressure bar above the wound, with two sets of second pressure bars on either side of the wound, and both the first and second pressure bars in contact with the patient's skin, when the patient raises their arm and causes the drive component to slide upward, the upward sliding of the drive component drives the first pressure bar and the two sets of second pressure bars to move toward the wound via the transmission mechanism. This movement of the first pressure bar and the two sets of second pressure bars toward the wound can move the skin around the wound toward the wound, thereby preventing the wound from tearing due to the patient pulling on the wound skin during the arm raising process, and making upper limb exercises convenient.

[0013] In one embodiment, the transmission mechanism includes a first transmission component and a second transmission component. The first transmission component is connected to the driving member and the first pressure rod, respectively. The first transmission component can convert the upward sliding of the driving member into the downward sliding of the first pressure rod. The second transmission component is connected to the first transmission component and two sets of second pressure rods, respectively. The second transmission component can convert the upward sliding of the driving member into the relative close movement of the two sets of second pressure rods through the first transmission component.

[0014] In one embodiment, the first transmission assembly includes a rotating shaft; the side wall of the fixing seat away from the patient's skin has an installation groove, and the rotating shaft is rotatably disposed in the installation groove along the length direction of the fixing seat. Gears are respectively disposed at both ends of the rotating shaft. Two sets of first racks are vertically disposed on the driving member, and the two sets of first racks slidably pass through the fixing seat into the installation groove and mesh with the two sets of gears. Two sets of second racks are vertically disposed on the first pressure rod, and the two sets of second racks slidably pass through the fixing seat into the installation groove and mesh with the two sets of gears. The first racks and second racks are staggered vertically. Moving the driving member upward causes the gears to rotate via the first racks, and the rotation of the gears meshing with the second racks causes the first pressure rod to move downward. Controlling the downward movement of the first pressure rod is convenient, avoiding upward pulling on the skin around the wound and preventing wound dehiscence.

[0015] In one embodiment, the second transmission assembly includes two sets of guide rods; both ends of the rotating shaft are provided with threaded portions, the two sets of threaded portions having opposite helical directions, and the two sets of guide rods are slidably disposed in the mounting groove along the length direction of the fixed seat, and are respectively threadedly connected to the two sets of threaded portions. The bottom surface of the mounting groove has a guide groove penetrating the fixed seat, and one end of each set of guide rods passes through the guide groove and is respectively connected to the two sets of second pressure rods. When the gear rotates, the gear drives the rotating shaft to rotate, and the rotation of the rotating shaft causes the two sets of guide rods to move relatively closer through the threaded engagement of the two sets of threaded portions and the two sets of guide rods. The relative movement of the two sets of guide rods can drive the two sets of second pressure rods to move relatively closer, making it convenient to move the two sets of second pressure rods, avoiding the skin around the wound being pulled by both sides, and preventing the wound from dehiscing.

[0016] In one embodiment, the second transmission assembly further includes two sets of sliding seats; the guide groove is an arc-shaped structure protruding towards the patient's skin, and the two sets of sliding seats can move along the arc of the guide groove. Each set of sliding seats has a groove at its upper end, and each set of guide rods has a lever at its lower end. The lever slidably passes through the groove, and the lower ends of the two sets of sliding seats are detachably connected to the two sets of second pressure rods. When the two sets of second pressure rods slide close to each other, the closer the two sets of pressure rods are to each other, the tighter the two sets of second pressure rods fit against the patient's skin, thus preventing slippage between the second pressure rods and the patient's skin, improving the wound's protection against lateral pulling, and enhancing the wound's protective effect.

[0017] In one embodiment, both sets of sliding seats have spring clip slots at their lower ends, and both sets of second pressure rods are equipped with spring clip buckles that can engage within the spring clip slots. This facilitates the installation and removal of the second pressure rods and allows for the replacement of second pressure rods of different sizes according to the size of the wound.

[0018] In one embodiment, the two sets of second pressure bars are arc-shaped structures that match the curvature of the wound. This facilitates the matching of the second pressure bars with the arc shape of the wound and makes it easier for the second pressure bars to contact the skin around the wound, thereby improving the tensile strength of the skin around the wound.

[0019] In one embodiment, a baffle is provided at the opening of the mounting slot, and the baffle is detachably connected to the fixing base. By blocking the mounting slot with the baffle, external debris can be prevented from entering the mounting slot and affecting the rotation of the shaft.

[0020] In one embodiment, the driving component includes a driving rod disposed at the upper end of the fixed base, one side of which can conform to the patient's axillary skin. When the patient raises their arm, the skin under the patient's arm moves upward, which in turn drives the driving rod upward, making it easy to move the driving rod upward.

[0021] In one embodiment, the contact surfaces of the drive rod, the first pressure rod, and the second pressure rod with the patient's skin are each detachably equipped with anti-slip pads made of rubber. This increases the friction between the drive rod, the first pressure rod, and the second pressure rod and the patient's skin, facilitating movement of the patient's skin while preventing pressure injuries. The detachable design also allows for easy replacement of the anti-slip pads. Attached Figure Description

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0033] Please see Figures 1 to 4 One embodiment of a post-masturbation upper limb exercise wound rupture prevention device includes a fixing base 10, a driving component, a first protective component, a second protective component, and a transmission mechanism 17.

[0034] The fixation base 10 can be fixed to the patient's skin. In one embodiment, both ends of the fixation base 10 are provided with fixing straps 14, and the free ends of the two sets of fixing straps 14 can be bonded together. By fitting the fixation base 10 to the patient's skin, and then wrapping the two sets of fixing straps 14 around the patient's body and bonding the free ends of the two sets of fixing straps 14 together, the fixation base 10 can be fixed to the patient's skin by the two sets of fixing straps 14, making the fixation base 10 easy to fix.

[0035] Please refer to the following: Figure 4 In one embodiment, the contact surface between the fixing seat 10 and the patient's skin is provided with anti-slip strips 103, and multiple sets of anti-slip strips 103 are spaced apart along the length of the fixing seat 10. When the fixing seat 10 is fixed to the patient's skin, the multiple sets of anti-slip strips 103 can contact the patient's skin, thereby increasing the friction between the fixing seat 10 and the patient's skin, and thus improving the stability of the fixing seat 10 fixed to the patient's skin.

[0036] The driving component is slidably mounted on the fixed base 10 along its height direction and slides upward when the patient raises their arm. Specifically, the driving component includes a driving rod 13, which is located at the upper end of the fixed base 10. One side of the driving rod 13 can fit against the patient's axillary skin. Because the driving rod 13 fits against the patient's axillary skin, when the patient raises their arm, the axillary skin moves upward, which in turn drives the driving rod 13 upward, making it easy to move the driving rod 13 upward.

[0037] The first protective component includes a first pressure rod 15, which is slidably mounted on the fixed base 10 along its height and located below the drive member. The second protective component includes two sets of second pressure rods 16, which are slidably mounted on the fixed base 10 along its length and located below the first pressure rod 15. One side of the first pressure rod 15 and the second pressure rod 16 can conform to the skin around the patient's wound. A transmission mechanism 17 is mounted on the fixed base 10 and connected to the drive member, the first pressure rod 15, and the two sets of second pressure rods 16, respectively, so that when the patient raises their arm, the sliding of the drive member is converted into a closing movement of the first pressure rod 15 and the two sets of second pressure rods 16 toward the wound.

[0038] When the patient raises their arm, causing the drive component to move upward, the transmission mechanism 17 drives the first pressure rod 15 and the two sets of second pressure rods 16 to move toward the wound. At this time, the first pressure rod 15 and the two sets of second pressure rods 16 can move the skin around the wound closer to the wound, thereby avoiding the skin around the wound from being pulled and causing the wound to rupture.

[0039] Please see Figure 2 , Figure 3 , Figure 4 , Figure 7 In one embodiment, the transmission mechanism 17 includes a first transmission component and a second transmission component. The first transmission component is connected to the driving member and the first pressure rod 15, respectively. The first transmission component can convert the upward sliding of the driving member into the downward sliding of the first pressure rod 15.

[0040] Specifically, the first transmission assembly includes a rotating shaft 172; a mounting groove 101 is provided on the side wall of the fixed seat 10 away from the patient's skin, the rotating shaft 172 is rotatably disposed in the mounting groove 101 along the length direction of the fixed seat 10, and gears 173 are respectively provided at both ends of the rotating shaft 172; two sets of first racks 171 are vertically arranged on the driving component, the two sets of first racks 171 can slide from the outside of the fixed seat 10 into the mounting groove 101 and mesh with the two sets of gears 173; two sets of second racks 174 are vertically arranged on the first pressure rod 15, the two sets of second racks 174 can slide from the outside of the fixed seat 10 into the mounting groove 101 and mesh with the two sets of gears 173; the first racks 171 and the second racks 174 are staggered in the vertical direction.

[0041] When the patient raises their arm, causing the drive component to slide upward, the drive component moves the first rack 171 upward. The upward movement of the first rack 171 engages with the gear 173, causing the gear 173 to rotate. The rotation of the gear 173 engages with the second rack 174, causing the second rack 174 to move downward. The downward movement of the second rack 174 causes the first pressure rod 15 to move downward. The downward movement of the first pressure rod 15 can move the skin on the upper side of the wound closer to the wound, thereby preventing the patient from pulling the skin on the upper side of the wound when raising their arm, thus preventing the wound from opening.

[0042] The second transmission assembly is connected to the first transmission assembly and the two sets of second pressure rods 16 respectively. The second transmission assembly can convert the upward sliding of the driving member into the relative close movement of the two sets of second pressure rods 16 through the first transmission assembly.

[0043] Specifically, the second transmission assembly includes two sets of guide rods 175; both ends of the rotating shaft 172 are provided with threaded portions 177, the two sets of threaded portions 177 have opposite helical directions, and the two sets of guide rods 175 are slidably disposed in the mounting groove 101 along the length direction of the fixed seat 10, and are respectively threaded onto the two sets of threaded portions 177. The upper ends of the two sets of guide rods 175 are respectively provided with first limiting sliders 1752, and the top side of the mounting groove 101 is provided with a first limiting groove 1011, in which the first limiting sliders 1752 are slidably locked, improving the stability of the sliding of the guide rods 175. The bottom surface of the mounting groove 101 is provided with a guide groove 102 that penetrates the fixed seat 10, and one end of the two sets of guide rods 175 passes through the guide groove 102 and is respectively connected to the two sets of second pressure rods 16.

[0044] When the patient raises their arm, causing the drive component to slide upwards, the drive component rotates gear 173. Gear 173 rotates, which in turn rotates shaft 172. Shaft 172 rotates, causing two sets of threaded portions 177 to rotate. The rotation of these threaded portions 177 engages with the threaded connections of two sets of guide rods 175, bringing them closer together. This movement of the guide rods 175 then moves the two sets of second pressure rods 16 closer together, which in turn moves the skin on both sides of the wound closer to the wound. This prevents the skin on both sides of the wound from being pulled when the patient raises their arm, thus preventing wound dehiscence. During arm-raising exercises, the first pressure rod 15 and the two sets of second pressure rods 16 prevent the skin around the wound from being pulled upwards and laterally, thus avoiding wound dehiscence during arm-raising exercises and facilitating upper limb exercises.

[0045] Please see Figure 4 , Figure 5In one embodiment, the second transmission assembly further includes two sets of sliding seats 176; the guide groove 102 is an arc-shaped structure protruding towards the patient's skin, and the two sets of sliding seats 176 can move along the arc of the guide groove 102. The sidewall of the guide groove 102 is provided with a second limiting groove 1021 along the arc of the guide groove 102, and the sidewall of the sliding seat 176 is provided with a second limiting slider 1761, which is slidably locked in the second limiting groove 1021. This improves the stability of the sliding seat 176 sliding in the guide groove 102. The upper end of each set of sliding seats 176 is provided with a groove 1762, and the lower end of each set of guide rods 175 is provided with a lever 1751, which can slide through the groove 1762. The lower ends of the two sets of sliding seats 176 are detachably connected to the two sets of second pressure rods 16 respectively.

[0046] In the above embodiment, when the two sets of guide rods 175 move closer to each other, the two sets of guide rods 175 move the sliding seat 176 along the guide groove 102 in an arc shape through the lever 1751. At this time, the lever 1751 slides in the groove 1762, and the two sets of sliding seats 176 drive the two sets of second pressure rods 16 to move closer to each other in an arc shape. The closer the relative distance between the two sets of second pressure rods 16, the tighter the two sets of second pressure rods 16 fit with the patient's skin, thereby avoiding slippage between the patient's skin and the second pressure rods 16, thereby improving the effect of the second pressure rods 16 in moving the patient's skin closer to the wound and preventing pulling.

[0047] Please see Figure 6 In one embodiment, each of the two sets of sliding seats 176 has a spring clip slot 1763 at its lower end, and each of the two sets of second pressure rods 16 is provided with a spring clip buckle 161, which can be engaged in the spring clip slot 1763. The second pressure rod 16 and the sliding seat 176 are detachably connected, which facilitates the installation and removal of the second pressure rod 16 and allows for the replacement of second pressure rods 16 of different sizes according to the size of the wound.

[0048] Please see Figure 1 In one embodiment, the two sets of second pressure rods 16 are arc-shaped structures that match the curvature of the wound. Since breast cancer surgery wounds are mostly arc-shaped, by setting the second pressure rods 16 with arc-shaped structures, it is easier for the second pressure rods 16 to contact the skin around the wound, thereby improving the tensile strength of the skin around the wound.

[0049] Please see Figure 1 , Figure 2In one embodiment, a baffle 11 is provided at the opening of the mounting groove 101. The baffle 11 is detachably connected to the fixing seat 10. Specifically, both ends of the baffle 11 are provided with connecting buckles, and the fixing seat 10 is provided with connecting slots 104 corresponding to the two sets of connecting buckles. The two sets of connecting buckles can be locked in the two sets of connecting slots 104. By blocking the mounting groove 101 with the baffle 11, it is possible to prevent external debris from entering the mounting groove 101 and affecting the rotation of the rotating shaft 172.

[0050] Please see Figure 2 In one embodiment, the contact surfaces of the drive rod 13, the first pressure rod 15, and the second pressure rod 16 with the patient's skin are each detachably equipped with anti-slip pads 12, which are made of rubber. This increases the friction between the drive rod 13, the first pressure rod 15, and the second pressure rod 16 and the patient's skin, facilitating movement of the patient's skin while preventing pressure injuries. The detachable design also makes it easy to replace the anti-slip pads 12.

[0051] The specific implementation method of the above-mentioned upper limb exercise wound rupture prevention device after breast surgery is as follows:

[0052] First, attach the fixing seat 10 to the patient's skin and place the drive rod 13 close to the skin under the patient's armpit. The first pressure rod 15 is located above the wound, and the two sets of second pressure rods 16 are located on both sides of the wound. Then, wrap the two sets of fixing straps 14 around the patient's body and connect the free ends of the two sets of fixing straps 14 together to fix the device to the patient.

[0053] When the patient performs arm-raising exercises, the skin under the armpit moves upward as the patient raises their arm. At this time, the drive rod 13 moves upward, which in turn moves the first rack 171 upward. The first rack 171 moves upward and meshes with the gear 173, causing the gear 173 to rotate. The rotation of the gear 173 meshes with the second rack 174, causing the second rack 174 to move downward. The downward movement of the second rack 174 moves the first pressure rod 15 downward. The downward movement of the first pressure rod 15 can move the skin above the wound downward and closer to the wound, thereby avoiding the upward pulling of the wound skin and preventing the wound from opening.

[0054] Simultaneously, the rotation of gear 173 drives the rotation of shaft 172, which in turn causes the two sets of threaded parts 177 to rotate. The rotation of the two sets of threaded parts 177 engages with the threaded engagement of the two sets of guide rods 175, allowing the guide rods 175 to move closer together. This movement of the guide rods 175, in turn, causes the two sets of second pressure rods 16 to move closer together. This movement of the second pressure rods 16 then moves the skin on both sides of the wound closer to the wound, thus preventing the skin on both sides of the wound from being pulled when the patient raises their arm, thereby preventing wound dehiscence. During arm-raising exercises, the first pressure rod 15 and the two sets of second pressure rods 16 prevent the skin around the wound from being pulled upwards and laterally, thus avoiding wound dehiscence during arm-raising exercises and facilitating upper limb exercises.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
