Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure relate to the technical field of medical auxiliary equipment, and in particular, to a pelvic fixing structure. Background Art
[0002] Pelvic fixation equipment is an important tool used in clinical medicine to treat pelvic fractures, soft tissue injuries and postoperative fixation. At present, common pelvic fixation devices are mainly divided into two categories: one is the pelvic external fixator, and the other is the bandage-type annular fixation belt. Although the external fixator can provide strong mechanical support, it is bulky, inconvenient to carry, and complicated to operate. It needs to be installed by professional medical personnel, which limits the feasibility of patients' daily activities and home rehabilitation. As an alternative to the external fixator, the bandage-type annular fixation belt is fixed by Velcro bonding, and the operation is relatively simple. However, the tightness of the traditional strap Velcro is difficult to control accurately after bonding, and it is easy to shift due to patient activities or changes in body position. It takes multiple adjustments to achieve the ideal state, which affects the user experience; at the same time, the existing straps are mostly made of a single dense fabric and lack a breathable design. Long-term wear can easily cause skin stuffiness, moisture, and even infection, reducing patient comfort. Summary of the invention
[0003] In order to overcome the above-mentioned defects, an embodiment of the present disclosure provides a pelvic fixation structure, which solves the technical problem that the pelvic fixation device in the prior art is difficult to have both good fixation effect and air permeability.
[0004] According to one aspect, at least one embodiment of the present disclosure provides a pelvic fixation structure for fixing the periphery of a patient's pelvis, comprising: A first annular fixing belt, wherein the first annular fixing belt has a first hard fixing portion and a first flexible connecting portion, wherein two ends of the first flexible connecting portion are respectively connected to two ends of the first hard fixing portion, and the first hard fixing portion is used to support the periphery of the patient's pelvis; a second annular fixing belt, wherein the second annular fixing belt is detachably and slidably arranged on the first annular fixing belt, A third annular fixing belt is detachably slidably arranged on the first annular fixing belt, the second annular fixing belt and the third annular fixing belt are respectively located at the upper and lower sides of the first annular fixing belt, and the first annular fixing belt, the second annular fixing belt and the third annular fixing belt are all used to wrap around the periphery of the patient's pelvis.
[0005] For example, at least one embodiment of the present disclosure provides a pelvic fixation structure, wherein the second annular fixation belt has a second rigid fixation portion, the third annular fixation belt has a third rigid fixation portion, the first rigid fixation portion has a first card slot and a second card slot on the lower and upper sides respectively, the second rigid fixation portion has a first snap-in portion, the third rigid fixation portion has a second snap-in portion, and the first snap-in portion and the second snap-in portion are used to snap into the first card slot and the second card slot respectively.
[0006] For example, in at least one embodiment of the present disclosure, a pelvic fixing structure is provided, wherein one end of the second hard fixing portion has a plurality of first adjustment clamping portions, and the pelvic fixing structure further comprises: a first swinging member, one end of which is hinged to one end of the second hard fixing portion; A second swinging member, one end of the second swinging member is hinged to the first swinging member, the other end of the second swinging member has a first clamping groove, the second swinging member is configured to make the first adjustment clamping part engage or cancel the engagement with the first clamping groove after swinging, and the second swinging member is simultaneously configured to move horizontally after being driven by the first swinging member to swing, so as to tighten the second annular fixing belt.
[0007] For example, in at least one embodiment of the present disclosure, a pelvic fixing structure is provided, wherein one end of the third hard fixing portion has a plurality of second adjustment clamping portions, and the pelvic fixing structure further comprises: a third swinging member, one end of which is hinged to one end of the third hard fixing portion; A fourth swinging member, one end of which is hinged to the third swinging member, and the other end of which has a second clamping groove. The fourth swinging member is configured to make the second adjustment clamping part engage or cancel the engagement with the second clamping groove after swinging, and the fourth swinging member is also configured to move horizontally after being driven by the third swinging member to swing, so as to tighten the third annular fixing belt.
[0008] For example, at least one embodiment of the present disclosure provides a pelvic fixing structure, wherein the pelvic fixing structure further includes: A fourth annular fixing belt, the fourth annular fixing belt is used to be put on the patient's waist; A fifth annular fixing belt, the fifth annular fixing belt is used to be sleeved on the patient's legs, and the fifth annular fixing belt has a third clamping portion; a first connecting rod, one end of which is swingably disposed on the fourth annular fixing belt; The second connecting rod has one end hinged to the first connecting rod and the other end having a third clamping slot, wherein the third clamping portion is clamped into the third clamping slot after the third clamping slot is driven by the second connecting rod to swing.
[0009] For example, at least one embodiment of the present disclosure provides a pelvic fixing structure, wherein the second connecting rod has a fourth clamping groove, and the second annular fixing belt has a fourth clamping portion, and the fourth clamping groove is configured to be driven by the second connecting rod to swing, so that the fourth clamping portion is clamped into or un-clamped into the fourth clamping groove, so as to limit or cancel the upward movement of the second annular fixing belt.
[0010] For example, in at least one embodiment of the present disclosure, a pelvic fixing structure is provided, wherein the second connecting rod also has a fifth clamping groove, and the third annular fixing belt has a fifth clamping portion, and the fifth clamping groove is configured to be driven by the second connecting rod to swing, so that the fifth clamping portion is clamped into or un-clamped into the fifth clamping groove, so as to limit or cancel the downward movement of the third annular fixing belt.

[0014] The beneficial effects of the embodiments of the present disclosure are: In the present disclosure, the tightening degree of the second annular fixing belt can be precisely adjusted through the cooperation between the first adjustment card part and the first clamped slot, and the linkage operation of the first and second swinging parts. Different patients have different pelvic conditions and treatment needs. This precise adjustment can enable the annular fixing belt to provide just the right fixing force, which not only ensures that the pelvis is stably supported, but also does not cause discomfort to the patient due to excessive tightness, thereby improving the comfort of fixation and the treatment effect. At the same time, after the first adjustment card part is engaged with the first clamped slot, a reliable connection can be formed, which effectively prevents the second annular fixing belt from loosening by itself during the patient's activities. Even if the patient performs some large-amplitude movements, the second annular fixing belt can maintain a stable fixed state, provide continuous and stable support for the pelvis, contribute to the normal recovery of the pelvis, and reduce the risk of secondary injury that may be caused by loose fixation.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0024] like Figure 1 to Figure 6As shown, it shows a pelvic fixation structure in an embodiment of the present disclosure, which is used to provide fixation for the periphery of the patient's pelvis, including a first annular fixation belt 1, the first annular fixation belt 1 has a first hard fixing portion 101 and a first flexible connection portion 102, the two ends of the first flexible connection portion 102 are respectively connected to the two ends of the first hard fixing portion 101, and the first hard fixing portion 101 is used to support the periphery of the patient's pelvis; the second annular fixation belt 2 is detachably slidably arranged on the first annular fixation belt 1, and the third annular fixation belt 3 is detachably slidably arranged on the first annular fixation belt 1, the second annular fixation belt 2 and the third annular fixation belt 3 are respectively located on the upper and lower sides of the first annular fixation belt 1, and the first annular fixation belt 1, the second annular fixation belt 2 and the third annular fixation belt 3 are all used to wrap around the periphery of the patient's pelvis.
[0025] For example, there are three different implementations in this embodiment. One: The first mode is a daily flexible wrapping state using only the first annular fixing belt 1: The first rigid fixing portion 101 of the first annular fixing belt 1 is designed to be a relatively thin and flexible structure, and is made of, for example, flexible plastic material, which can provide certain support and adapt to daily body activities. The first flexible connecting portion 102 is made of skin-friendly, breathable elastic fabric, such as Lycra fabric, and its two ends are firmly connected to the two ends of the first rigid fixing portion 101.
[0026] When in use, the first annular fixing belt 1 is wrapped around the patient's pelvis, and the first hard fixing part 101 is aligned with the key supporting position of the pelvis, such as the stress point on the front or outside of the pelvis. The first flexible connecting part 102 bends naturally with the body and uses its own elasticity to fit the body, providing the pelvis with the flexible wrapping support required for daily activities, without hindering the patient from performing some simple daily activities, such as slow walking, sitting posture adjustment, etc.
[0027] 2: The second method is a full-range hard fixation state in which three annular fixing belts are used simultaneously: The first hard fixing part 101 of the first annular fixing belt 1 is made of a harder material, such as aluminum alloy, to provide strong support for the pelvis. The first flexible connecting part 102 still connects the two ends to connect and assist in fitting the body.
[0028] The second annular fixing belt 2 and the third annular fixing belt 3 are also made of hard materials, such as high-strength plastic, and are detachably connected to the slide groove on the first annular fixing belt 1 through a slider. When in use, the first annular fixing belt 1 is first wrapped around the pelvis and initially fixed. According to the specific conditions of the patient's pelvis, the second annular fixing belt 2 and the third annular fixing belt 3 are slid to appropriate positions along the slide groove of the first annular fixing belt 1. For example, the second annular fixing belt 2 can be located above the pelvis near the iliac crest, and the third annular fixing belt 3 is located below the pelvis near the pubic symphysis. Then the three annular fixing belts are tightened around the pelvis to form an all-round hard fixation, which provides comprehensive and stable support for the pelvis, and is suitable for emergency situations or treatment stages that require strict restriction of pelvic movement.
[0029] 3: The third method is to remove the temporary support state of the first annular fixing belt 1: The first annular fixing belt 1 is quickly disassembled by providing a quick disassembly structure at the first flexible connection portion 102. When ventilation, cleaning or physiological needs are required, the quick disassembly structure is opened to disassemble the first annular fixing belt 1.
[0030] At this time, the second annular fixing belt 2 and the third annular fixing belt 3 have been adjusted to the appropriate position and fastened before, and continue to provide hard restraint and temporary support to the pelvis. Their hard materials and reasonable position distribution can maintain the relative stability of the pelvis to a certain extent, meet the basic activity needs of the patient in a short period of time, and avoid the risk of pelvic displacement caused by complete removal of the fixing device.
[0031] In some examples, the second annular fixing belt 2 has a second rigid fixing portion 201, the third annular fixing belt 3 has a third rigid fixing portion 301, the first rigid fixing portion 101 has a first card slot 103 and a second card slot 104 on the lower and upper sides respectively, the second rigid fixing portion 201 has a first snap-in portion 202, the third rigid fixing portion 301 has a second snap-in portion 302, and the first snap-in portion 202 and the second snap-in portion 302 are used to snap into the first card slot 103 and the second card slot 104 respectively.
[0032] For example, Figure 2As shown, the first rigid fixing part 101 of the first annular fixing belt 1 is provided with a first slot 103 and a second slot 104 on both sides. The shape of the slot can be designed as a dovetail slot or a circular slot or a strip slot structure that matches the snap-in part. This design not only ensures the stability of the connection, but also facilitates snap-in and disassembly. The slot is longitudinally distributed along the edge of the first rigid fixing part 101, and runs through a certain length to meet the snap-in requirements of the second annular fixing belt 2 and the third annular fixing belt 3 at different positions. Through the snap-in connection mode of the first snap-in part 202 and the first slot 103, and the second snap-in part 302 and the second slot 104, the connection between the second annular fixing belt 2 and the third annular fixing belt 3 and the first annular fixing belt 1 is more stable and reliable. During the patient's activities, the second annular fixing belt 2 and the third annular fixing belt 3 can be effectively prevented from slipping or shifting from the first annular fixing belt 1, ensuring that the pelvic fixing structure always maintains a stable fixing effect, providing reliable protection for the recovery of the pelvis.
[0033] The design of the card slot and the card-in portion ensures a stable connection while facilitating the installation and removal of the second annular fixing belt 2 and the third annular fixing belt 3. During use, medical staff or patients can quickly and conveniently connect or separate the second and third annular fixing belts from the first annular fixing belt, saving time and energy and improving the convenience of use, whether in the initial installation, position adjustment or subsequent care.
[0034] In some examples, one end of the second hard fixing portion 201 has a plurality of first adjustment clamping portions 203, and a pelvic fixing structure also includes a first swinging member 4, one end of the first swinging member 4 is hinged to one end of the second hard fixing portion 201; one end of the second swinging member 5 is hinged to the first swinging member 4, and the other end of the second swinging member 5 has a first clamping groove 501, and the second swinging member 5 is configured to make the first adjustment clamping portion 203 engage in or cancel the engagement in the first clamping groove 501 after swinging, and the second swinging member 5 is also configured to move horizontally after being driven by the first swinging member 4 to swing, so as to tighten the second annular fixing belt 2.
[0035] For example, Figures 4 and 5 The structures of the second annular fixing belt 2 and the third annular fixing belt 3 are similar. When the second annular fixing belt 2 needs to be tightened, the operator holds the first swinging member 4 and swings it in a direction away from the second hard fixing portion 201, driving the second swinging member 5 to move synchronously. During the swinging process, the second swinging member 5 will move horizontally. This is due to the movement trajectory determined by the two hinge points and the overall structural design. At the same time, the second swinging member 5 swings around the hinge point with the first swinging member 4, so that the first adjustment clamping portion 203 gradually approaches and is clamped into the first clamping groove 501. As the swing amplitude increases, more first adjustment clamping portions 203 are clamped into the first clamping groove 501, thereby shortening the effective length of the second annular fixing belt 2 and achieving a tightening effect.
[0036] If the second annular fixing belt 2 needs to be loosened, the first swinging member 4 is swung in the opposite direction, so that the first adjustment clamping portion 203 is gradually withdrawn from the first clamped slot 501, thereby increasing the effective length of the second annular fixing belt 2. Through the cooperation between the first adjustment clamping portion 203 and the first clamped slot 501, and the linkage operation of the first and second swinging members, the degree of tightening of the second annular fixing belt 2 can be precisely adjusted. Different patients have different pelvic conditions and treatment needs. This precise adjustment can enable the annular fixing belt to provide just the right fixing force, which not only ensures that the pelvis is stably supported, but also does not cause discomfort to the patient due to excessive tightening, thereby improving the comfort of fixation and the treatment effect. At the same time, after the first adjustment clamping portion 203 is engaged with the first clamped slot 501, a reliable connection can be formed, effectively preventing the second annular fixing belt 2 from loosening itself during the patient's activities. Even if the patient performs some large-amplitude movements, the second annular fixing belt 2 can maintain a stable fixed state, provide continuous and stable support for the pelvis, help the normal recovery of the pelvis, and reduce the risk of secondary injury that may be caused by loose fixation.
[0037] In some examples, one end of the third hard fixing portion 301 has a plurality of second adjustment clamping portions 303, and a pelvic fixing structure also includes a third swinging member 6, one end of the third swinging member 6 is hinged to one end of the third hard fixing portion 301; one end of a fourth swinging member 7 is hinged to the third swinging member 6, and the other end of the fourth swinging member 7 has a second clamping groove 701, and the fourth swinging member 7 is configured to make the second adjustment clamping portion 303 engage in or cancel the engagement in the second clamping groove 701 after swinging, and the fourth swinging member 7 is also configured to move horizontally after being driven by the third swinging member 6 to swing, so as to tighten the third annular fixing belt 3.
[0038] For example, Figures 4 and 5 As shown, similar to the adjustment structure of the second annular fixing belt 2, the third annular fixing belt 3 can accurately adjust the tightening degree of the third annular fixing belt 3 through the cooperation of the second adjustment clamping portion 303 and the second clamped groove 701 and the linkage of the third and fourth swinging members. Different patients have different pelvic shapes, injury degrees and recovery stages. This precise adjustment can ensure that the third annular fixing belt 3 provides the most suitable fixing force, meet personalized treatment needs, and help improve the treatment effect.
[0039] In some examples, a pelvic fixation structure also includes a fourth annular fixation belt 8, which is used to be mounted on the patient's waist; a fifth annular fixation belt 9 is used to be mounted on the patient's legs, and the fifth annular fixation belt 9 has a third clamping portion 901; one end of the first connecting rod 10 is swingably set on the fourth annular fixation belt 8; one end of the second connecting rod 11 is hinged to the first connecting rod 10, and the other end has a third clamping groove 1101, and the third clamping groove 1101 is configured so that after being driven by the second connecting rod 11 to swing, the third clamping portion 901 is clamped into the third clamping groove 1101.
[0040] For example, during installation, the fourth annular fixing belt 8 is first fixed to the patient's waist, and the fifth annular fixing belt 9 is fixed to the patient's legs. Then, the first connecting rod 10 is swung to drive the second connecting rod 11 to move. The position of the second connecting rod 11 is adjusted to align the third clamping groove 1101 with the third clamping portion 901, and the first connecting rod 10 is continuously swung to allow the second connecting rod 11 to swing until the third clamping portion 901 is clamped into the third clamping groove 1101, thereby establishing a connection between the waist and the legs, and enhancing the stability of the pelvic fixation.
[0041] In some examples, the second connecting rod 11 has a fourth clamping slot 1102, and the second annular fixing belt 2 has a fourth clamping portion 204. The fourth clamping slot 1102 is configured to be driven by the second connecting rod 11 to swing, so that the fourth clamping portion 204 is clamped into or un-clamped into the fourth clamping slot 1102, so as to limit or cancel the upward movement of the second annular fixing belt 2.
[0042] In some examples, the second connecting rod 11 also has a fifth clamping slot 1103, and the third annular fixing belt 3 has a fifth clamping portion 304. The fifth clamping slot 1103 is configured to be driven by the second connecting rod 11 to swing, so that the fifth clamping portion 304 is clamped into or un-clamped into the fifth clamping slot 1103, so as to limit or cancel the restriction on the downward movement of the third annular fixing belt 3.
[0043] For example, in this embodiment, there are two working states; The first is an overall fixation strategy in a serious injury scenario: when the patient's pelvic area is seriously injured, the various parts of the pelvic fixation structure work together to achieve a more stable fixation of the human body. The second is that the first annular fixation belt 1 can still ensure good fastening and supporting performance after being removed.
[0044] During the installation process, the medical staff first firmly fixes the fourth annular fixing belt 8 on the patient's waist, and the fifth annular fixing belt 9 is wrapped around the patient's legs in a suitable position and fixed. Then, carefully swing the first connecting rod 10 to drive the second connecting rod 11 to swing, so that the fourth clamping groove 1102 is aligned with the fourth clamping portion 204 of the second annular fixing belt 2, and the fifth clamping groove 1103 is aligned with the fifth clamping portion 304 of the third annular fixing belt 3. Due to the serious injuries of the patient, the operation needs to be extremely cautious to avoid secondary injuries. Then, slowly and accurately continue to swing the second connecting rod 11, so that the fourth clamping portion 204 is gradually clamped into the fourth clamping groove 1102, and the fifth clamping portion 304 is clamped into the fifth clamping groove 1103, until the best clamping state is reached, thereby forming a stable constraint on the second annular fixing belt 2 and the third annular fixing belt 3, respectively, to prevent the second annular fixing belt 2 from moving up and the third annular fixing belt 3 from moving down. The coordinated operation of the first annular fixing belt 1, the second annular fixing belt 2, the third annular fixing belt 3, the fourth annular fixing belt 8 and the fifth annular fixing belt 9 and the connecting rod structure realizes the all-round and multi-level fixation of the pelvis and surrounding body parts. From directly supporting the pelvis to stabilizing the waist and legs, the multi-part and multi-angle fixation mode significantly reduces the relative movement between the parts, greatly reduces the risk of pelvic re-injury, and provides a strong guarantee for the patient's body stability during treatment. Even in the case of serious injury, the structure still retains good adjustability. The first connecting rod 10 and the second connecting rod 11 realize the engagement and separation of the fourth clamping part 204 and the fourth clamping groove 1102, and the fifth clamping part 304 and the fifth clamping groove 1103, which is convenient for medical staff to accurately fine-tune the fixing structure according to the patient's injury changes or treatment needs. While ensuring flexibility, the high-strength design of the overall structure ensures the high reliability of fixation, providing safe and effective fixation for patients with serious pelvic injuries.
[0045] In some examples, the fourth clamping portion 204 and the fifth clamping portion 304 are respectively disposed on the second rigid fixing portion 201 and the third rigid fixing portion 301 in a one-to-one correspondence.
[0046] For example, the fourth clamping portion 204 and the fifth clamping portion 304 are respectively arranged on the second rigid fixing portion 201 and the third rigid fixing portion 301, so that the connection between the second annular fixing belt 2 and the third annular fixing belt 3 and the second connecting rod 11 is more accurate and stable. For patients with severe pelvic injuries, this precise structural design can better withstand the force generated by the movement of the patient's body, effectively prevent the displacement of the annular fixing belt, and ensure that the pelvis recovers in a stable environment.
[0047] In some examples, the fourth annular fixing belt 8 and the fifth annular fixing belt 9 are bonded, sleeved or clamped.
[0048] In some examples, the first annular fixing belt 1 , the second annular fixing belt 2 , the third annular fixing belt 3 , the fourth annular fixing belt 8 , and the fifth annular fixing belt 9 are all provided with flexible materials inside.
[0049] For example, by arranging the above-mentioned different flexible materials inside the first annular fixing belt 1, the second annular fixing belt 2, the third annular fixing belt 3, the fourth annular fixing belt 8 and the fifth annular fixing belt 9, not only the effective fixation of the pelvis by the pelvic fixing structure is ensured, but also the comfort of the user when wearing it is greatly improved.
