Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a hip and leg braking device. Background Technology

[0002] After a temporary pacemaker is implanted via femoral vein puncture or after cerebral angiography via femoral artery puncture, the patient's lower limbs need to be immobilized.

[0003] The device provided by the related technology achieves immobilization of the patient's lower limbs by immobilizing the patient's thigh. At this time, the patient can still raise the lower leg by moving the knee, which may lead to problems such as temporary pacemaker displacement after surgery or bleeding at the puncture site after cerebral angiography, thus posing risks.

[0004] The above analysis shows that the relevant technology has the technical problem of not being able to simultaneously immobilize the patient's thigh and calf to prevent the patient's lower limbs from bending. This can lead to problems such as temporary pacemaker displacement after surgery or bleeding at the puncture site after cerebral angiography, which bring risks. Utility Model Content

[0026] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] It should be noted that the hip and leg braking device provided in this application embodiment can be used in the field of medical device technology, or in any field other than the field of medical device technology. The application field of the hip and leg braking device in this application is not limited.

[0029] The hip and leg immobilization device provided in this application embodiment is specifically applied to scenarios where the patient's lower limbs are immobilized after a temporary pacemaker implanted via femoral vein puncture or after cerebral angiography via femoral artery puncture. It can be worn on the patient's hip and one lower limb.

[0030] Temporary pacemaker implantation via femoral vein puncture is a surgical procedure that delivers a pacing electrode to the right ventricle through the femoral vein to treat bradycardia. During the procedure, the surgeon selects the right femoral vein for puncture. Through this puncture point, the pacing electrode passes through the femoral vein and inferior vena cava, enters the right atrium, and then passes through the tricuspid valve into the right ventricle.

[0031] Cerebral angiography via femoral artery puncture is a procedure in which contrast agent is injected into the blood vessel through a puncture of the femoral artery to visualize the course, structure, and blood flow of cerebral blood vessels.

[0032] After this type of surgery, the lower limb on the implanted side must be immobilized to restrict movement and reduce irritation and damage to the puncture site, thereby minimizing potential postoperative risks. Simultaneously, the puncture site should be closely monitored post-operatively so that any abnormalities can be promptly reported to the doctor for appropriate intervention.

[0033] The device provided by the related technology achieves immobilization of the patient's lower limbs by immobilizing the patient's thigh. At this time, the patient can still raise the lower leg by moving the knee, which may lead to problems such as temporary pacemaker displacement after surgery or bleeding at the puncture site after cerebral angiography, thus posing risks.

[0034] Meanwhile, the devices provided by the relevant technologies cannot conveniently observe the puncture site while protecting it. These devices either protect the puncture site by setting up a shielding part, requiring the device to be detached from the patient's lower limb for observation, or they fail to protect the puncture point for easy observation.

[0035] The above analysis shows that the relevant technology has technical problems, such as the inability to simultaneously immobilize the patient's thigh and calf, and the inability to observe the puncture site while protecting it.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0037] Combination Figure 1 , Figure 2 , Figure 1 Strabismus of the hip and leg braking device provided in the embodiments of this application Figure 1 , Figure 2 Strabismus of the hip and leg braking device provided in the embodiments of this application Figure 2 ,like Figure 1 and Figure 2 As shown, the hip and leg braking device provided in this application embodiment can be worn on the patient's hip and one lower limb, including: hip fixator 1, thigh fixator 2, lower leg fixator 3 and support plate 4.

[0038] Among them, hip fixation device 1 is used to wrap the patient's hip, thigh fixation device 2 is used to wrap the patient's thigh on one side, and calf fixation device 3 is used to wrap the patient's calf on that side.

[0039] The support plate 4 passes through the hip fixator 1, thigh fixator 2 and calf fixator 3, and is located inside the hip fixator 1, thigh fixator 2 and calf fixator 3, to prevent the patient's lower limb from bending.

[0040] The hip and leg braking device provided in this application can be worn on the hip and right lower limb, or it can be worn on the hip and left lower limb. The following description uses the device worn on the hip and right lower limb as an example.

[0041] During use, the patient wears the hip and leg immobilization device, such as after a temporary pacemaker implantation via femoral vein puncture or a cerebral angiography via femoral artery puncture. The patient wears the hip and right lower limb immobilization device, with the hip fixator 1 wrapping around the entire hip, the thigh fixator 2 wrapping around the right thigh, and the lower leg fixator 3 wrapping around the right lower leg. At the same time, the support plate 4 runs through the hip fixator 1, thigh fixator 2, and lower leg fixator 3, and is located inside the hip fixator 1, thigh fixator 2, and lower leg fixator 3. The support plate 4 connects the hip fixator 1, thigh fixator 2, and lower leg fixator 3 into a whole. At the same time, the support plate 4 has a supporting function, supporting the patient's hip, thigh, and lower leg, thereby achieving simultaneous immobilization of the patient's hip, thigh, and lower leg to prevent the patient's lower limb from bending.

[0042] The hip and leg braking device provided in this application embodiment, by setting a hip fixator 1 to wrap around the patient's hip, a thigh fixator 2 to wrap around the patient's thigh on one side, and a calf fixator 3 to wrap around the patient's calf on the same side, and a support plate 4 that runs through the hip fixator 1, thigh fixator 2 and calf fixator 3, achieves the technical effect of simultaneously braking the patient's hip, thigh and calf, preventing the patient's lower limb from bending, thereby effectively preventing displacement of surgically implanted instruments or bleeding at the puncture site, and reducing postoperative risks.

[0043] In some implementations, since different patients have different weights, the hip-leg braking device needs to be adapted to patients of different weights. Therefore, different numbers of support plates 4 can be set according to the patient's weight. The number of support plates 4 includes two or more, and the two or more support plates 4 are arranged in parallel.

[0044] As an example, such as Figure 1 , Figure 2 As shown, three parallel support plates 4 can be fixed on the inner side of the hip fixator 1, the inner side of the thigh fixator 2, and the inner side of the calf fixator 3 of the hip and leg braking device. After the patient wears the hip and leg braking device, the three parallel support plates 4 are positioned on the back of the patient's hip and lower limb to brake the back of the patient's hip and lower limb, thereby preventing the patient's lower limb from bending.

[0045] In these embodiments, by providing different numbers of support plates 4 on the inner side of the hip and leg fixator 1, the inner side of the thigh fixator 2, and the inner side of the calf fixator 3 of the hip and leg braking device, the practicality of the hip and leg braking device is improved to accommodate patients of different weights.

[0046] In some embodiments of these implementations, since the support plate 4 of the hip and leg braking device mainly serves as a support and brake, the support plate 4 needs to have a certain rigidity to ensure that the support plate 4 can simultaneously bear the weight of the patient's hip and lower limb, help maintain the correct position of the leg during the healing process, and prevent unnecessary movement; at the same time, since wearing the hip and leg braking device for a long time can cause discomfort in the patient's lower limb, the support plate 4 includes at least one arc-shaped structure, which makes the support plate 4 fit the patient's hip, thigh and calf.

[0047] Specifically, at least one arc-shaped structure of the support plate 4 can be configured according to the curves of the patient's hip, thigh, and calf, so that the support plate 4 fits the patient's hip, thigh, and calf.

[0048] In these embodiments, by designing the support plate 4 as at least one arc-shaped structure, the support plate 4 can conform to the patient's hip, thigh and calf, thereby improving the comfort of the hip and leg braking device.

[0049] In some of these implementations, since the hip curve, thigh curve, and calf curve are different for different patients, and for the hip and leg braking device with multiple support plates 4, the multiple support plates 4 arranged in parallel on the inner side of the hip fixator 1, the inner side of the thigh fixator 2, and the inner side of the calf fixator 3 support different parts of the patient's hip, thigh, and calf, and the curves of different parts of the patient's hip, thigh, and calf are also different, the size of the arc of the arc structure can be adjusted.

[0050] It should be noted that, since the main support plate 4 is used to support and immobilize the patient's hip and lower limbs, the curvature of the arc structure can only be adjusted slightly.

[0051] In these embodiments, by adjusting the curvature of the arc structure of the support plate 4, the hip and leg braking device can fit more closely to the patient's hip, thigh, and calf, thereby further improving the comfort of the hip and leg braking device.

[0052] In some embodiments of these implementations, in order to ensure that the support plate 4 has a certain rigidity to ensure the braking effect of the device on the patient's hip, thigh and calf, while ensuring that the support plate 4 has a high degree of comfort, the material of the support plate 4 includes one or more of the following: steel and aluminum.

[0053] It should be noted that other materials that can simultaneously meet the above conditions can also be used to make support plate 4, and this application does not limit them.

[0054] In these embodiments, the support plate 4, made of steel, aluminum or other materials, is lightweight and has a certain rigidity, while also allowing for fine-tuning of the curvature of the support plate 4, ensuring the braking effect of the hip and leg braking device while taking into account the comfort of the device.

[0055] In some embodiments of these implementations, in order to protect the patient's puncture site and facilitate observation of the puncture site by the patient and medical staff, the hip fixator 1 and the thigh fixator 2 are connected; a transparent observation window 5 is provided in the connection area of ​​the hip fixator 1 and the thigh fixator 2, wherein the transparent observation window 5 is located at the site for observing the patient's wound.

[0056] As an example, since the puncture point for temporary pacemaker surgery via femoral vein puncture or cerebral angiography surgery via femoral artery puncture is located on the front of the right thigh, after the patient wears the hip and leg immobilizer, the support plate 4 of the hip and leg immobilizer fits against the patient's right posterior hip, the back of the right thigh, and the back of the right calf, while the transparent observation window 5 is set opposite to the support plate 4, specifically in the connection area between the hip fixator 1 and the thigh fixator 2.

[0057] In these embodiments, a transparent observation window 5 is provided in the connection area between the hip fixator 1 and the thigh fixator 2, and the transparent observation window 5 is placed at the site of observation of the patient's wound to protect the patient's puncture site, while also facilitating the patient or medical staff to observe the condition of the puncture site at any time.

[0058] In some embodiments of these implementations, in order to ensure that the transparent observation window 5 has the above-mentioned properties, the material of the transparent observation window 5 needs to have high transparency, as well as scratch resistance, wear resistance and anti-fog properties. Therefore, the transparent observation window 5 is made of one or more of the following materials: PVC material and polyurethane material.

[0059] In these embodiments, the transparent observation window 5 is made of PVC and / or polyurethane materials, which protects the patient's puncture site while ensuring the transparency of the transparent observation window 5 so that the patient or medical staff can easily observe the puncture site.

[0060] In some embodiments of these implementations, since the hip and leg braking device needs to be worn on the patient's hip and lower limb, to facilitate wearing the hip and leg braking device, one end of the hip fixator 1 is provided with a first connecting device 6 and the other end is provided with a second connecting device 7, and the first connecting device 6 and the second connecting device 7 are connected in cooperation.

[0061] The thigh fixation device 2 is provided with a third connecting device 8 at one end and a fourth connecting device 9 at the other end, and the third connecting device 8 and the fourth connecting device 9 are connected together.

[0062] The lower leg fixation device 3 has a fifth connecting device 10 at one end and a sixth connecting device 11 at the other end, and the fifth connecting device 10 and the sixth connecting device 11 are connected together.

[0063] As an example, such as Figure 1 and Figure 2 As shown, the first connecting device 6 can be located at the middle of one end of the hip fixator 1, and the second connecting device 7 can be located at the middle of the other end of the hip fixator 1, so that after the patient wears the hip-leg braking device, the first connecting device 6 and the second connecting device 7 are positioned at the patient's anterior hip. The third connecting device 8 can be located at the middle and lower part of one end of the thigh fixator 2, and the fourth connecting device 9 can be located at the middle and lower part of the other end of the thigh fixator 2, so that after the patient wears the hip-leg braking device, the third connecting device 8 and the fourth connecting device 9 are positioned at the front of the patient's thigh and knee. The fifth connecting device 10 can be located at the middle of one end of the calf fixator 3, and the sixth connecting device 11 can be located at the middle of the other end of the calf fixator 3, so that after the patient wears the hip-leg braking device, the fifth connecting device 10 and the sixth connecting device 11 are positioned at the front of the patient's calf.

[0064] During the wearing of the hip and leg immobilization device, the patient or medical staff can open the hip fixator 1, thigh fixator 2, and calf fixator 3 respectively. Then, the hip fixator 1 is used to wrap around the patient's hip, and the first connecting device 6 and the second connecting device 7 are connected to fix the hip. The thigh fixator 2 is used to wrap around the patient's thigh, and the third connecting device 8 and the fourth connecting device 9 are connected to fix the thigh. The calf fixator 3 is used to wrap around the patient's calf, and the fifth connecting device 10 and the sixth connecting device 11 are connected to fix the calf.

[0065] In these embodiments, by providing a first connecting device 6 at one end of the hip fixator 1 and a second connecting device 7 at the other end, a third connecting device 8 at one end of the thigh fixator 2 and a fourth connecting device 9 at the other end, and a fifth connecting device 10 at one end of the calf fixator 3 and a sixth connecting device 11 at the other end, the hip and leg braking device is made easier to wear and the operating efficiency is improved.

[0066] In some of these implementations, since the hip circumference, thigh circumference and calf circumference of different patients are different, in order to ensure that the hip and leg braking device can be adapted to the hip, thigh and calf of different patients, the hip fixator 1, thigh fixator 2 and calf fixator 3 support adjustable size of their respective wrapping circumference.

[0067] Specifically, the tightness of the connection between the first connecting device 6 and the second connecting device 7 in wrapping the patient's hip, the tightness of the connection between the third connecting device 8 and the fourth connecting device 9 in wrapping the patient's thigh, and the tightness of the connection between the fifth connecting device 10 and the sixth connecting device 11 in wrapping the patient's calf are adjustable.

[0068] As an example, the first connecting device 6 may include a card head, and the second connecting device 7 may include a card tape. The first connecting device 6 and the second connecting device 7 are connected by the card head and the card tape.

[0069] The third connecting device 8 may include a card head, and the fourth connecting device 9 may include a card tape. The third connecting device 8 and the fourth connecting device 9 are connected by the card head and the card tape.

[0070] The fifth connecting device 10 may include a card head, and the sixth connecting device 11 may include a card tape. The fifth connecting device 10 and the sixth connecting device 11 are connected by the card head and the card tape.

[0071] As an example, the first connecting device 6 may include hook-and-loop fasteners, and the second connecting device 7 may include loop fasteners. The first connecting device 6 and the second connecting device 7 are connected by the hook-and-loop fasteners and the loop fasteners.

[0072] The third connecting device 8 may include hook and loop fasteners, and the fourth connecting device 9 may include loop fasteners with a fleece surface. The third connecting device 8 and the fourth connecting device 9 are connected by the hook and loop fasteners and the fleece surface fasteners.

[0073] The fifth connecting device 10 may include hook and loop fasteners, and the sixth connecting device 11 may include loop fasteners with a velvet surface. The fifth connecting device 10 and the sixth connecting device 11 are connected by the hook and loop fasteners and the velvet surface fasteners.

[0074] As an example, the first connecting device 6 may include a strap, the second connecting device 7 may include a strap, and the first connecting device 6 and the second connecting device 7 are connected by the strap.

[0075] The third connecting device 8 may include a strap, and the fourth connecting device 9 may include a strap. The third connecting device 8 and the fourth connecting device 9 are connected by the strap.

[0076] The fifth connecting device 10 may include a strap, and the sixth connecting device 11 may include a strap. The fifth connecting device 10 and the sixth connecting device 11 are connected by the strap.

[0077] In these embodiments, by providing buckle devices, Velcro devices, or strap devices on the first connecting device 6, the second connecting device 7, the third connecting device 8, the fourth connecting device 9, the fifth connecting device 10, and the sixth connecting device 11 to adjust the tightness of the hip fixator 1, the thigh fixator 2, and the calf fixator 3 respectively, the tightness of the hip fixator 1 wrapping the patient's hip, the thigh fixator 2 wrapping the patient's thigh, and the calf fixator 3 wrapping the patient's calf can be adjusted as needed, thereby improving the comfort and practicality of the hip and leg braking device.

[0078] In some of these implementations, wearing the hip and leg immobilizer for a long time puts the patient's hip, thigh and calf in a relatively enclosed space, which can easily cause the space to be damp and thus cause discomfort. Therefore, the hip fixator 1, thigh fixator 2 and calf fixator 3 are each provided with multiple ventilation holes.

[0079] In these embodiments, by providing multiple ventilation holes in the hip fixator 1, thigh fixator 2, and calf fixator 3, the ventilation and perspiration functions of the hip and leg immobilization device are enhanced, thereby keeping the patient's skin dry and reducing infection or discomfort caused by moisture.

[0080] In some embodiments of these implementations, to make the hip-leg immobilizer more comfortable to wear, the hip fixator 1, thigh fixator 2, and calf fixator 3 are each made of a stretchable, flexible material. This allows the hip fixator 1, thigh fixator 2, and calf fixator 3 to work together with the support plate 4 so that after the patient wears the hip-leg immobilizer, the pressure of the hip-leg immobilizer is evenly distributed on the key support points of the patient's hip and lower limb. This reduces the pressure on the local skin caused by prolonged immobilization of the patient's hip and lower limb, lowers the risk of pressure sores, and maintains the stability of the postoperative puncture site guidewire.

[0081] As an example, when a patient wears a hip-leg immobilizer, the pressure can be evenly distributed at the following key support points:

[0082] In the hip region, this includes the anterior superior iliac spine and the ischial tuberosity. The anterior superior iliac spine, as an important bony landmark of the pelvis, plays a fundamental role in positioning and supporting the hip-leg immobilizer when the patient is supine. It effectively limits excessive hip abduction and rotation, ensuring the stability of the fixation. The ischial tuberosity primarily bears part of the patient's body weight on the buttocks. Proper support provided by the hip-leg immobilizer at this location prevents the body from sinking or shifting, maintaining overall lower limb stability. This is crucial for maintaining the stability of the pacing lead postoperatively, preventing lead traction or displacement due to hip movement.

[0083] In the thigh region, this includes the greater trochanter of the femur and the mid-shaft of the femur. The greater trochanter is more prominent in the supine position and is a crucial pressure point for the hip-leg immobilizer to fix the lateral aspect of the thigh, preventing lateral movement of the thigh and ensuring alignment and positional fixation of the lower limb. The mid-shaft of the femur plays a key role in bearing the patient's body weight. The hip-leg immobilizer distributes pressure evenly here, effectively reducing pressure on the local skin of the thigh, lowering the risk of pressure sores, and maintaining relative stability of the thigh muscles and bones, preventing muscle contraction or bone movement from affecting the fixation effect.

[0084] In the knee joint area, including the femoral condyle and tibia, when the patient is supine with the knee extended, the femoral condyle and tibial plateau are in close contact. The hip-leg immobilization device needs to provide appropriate support at this point to ensure that the knee joint is maintained in a functional position, preventing excessive flexion, extension, or varus / valgus, ensuring normal transmission of force lines in the lower limb, and avoiding compression or damage to the ligaments, menisci, and other structures around the knee joint. This helps maintain the stability and comfort of the entire lower limb and promotes postoperative recovery.

[0085] In the lower leg, including the area near the anterior tibial border and the Achilles tendon attachment point, the anterior tibial border is relatively superficial and bears certain pressure from the skin and soft tissues when the patient is supine. The hip-leg immobilizer effectively distributes pressure here to prevent excessive pressure on the anterior skin of the lower leg, ensuring unobstructed blood circulation. Through precise biomechanical analysis and design, the pressure of the hip-leg immobilizer is evenly distributed at key support points of the lower limb, reducing pressure on the local skin from prolonged immobilization, lowering the risk of pressure sores, and maintaining the stability of the postoperative pacing lead.

[0086] In these embodiments, the hip fixator 1, thigh fixator 2, and calf fixator 3 are made of stretchable flexible materials, so that the hip and leg braking device can be adapted to the hip and right lower limb shape of different patients, thereby ensuring that the hip and leg braking device fits the patient's hip and right lower limb shape closely, making the hip and leg braking device more comfortable to wear.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the following claims.

[0088] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
