Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a transverse bone transport bracket for ilium and a method of using the bracket. Background Art

[0002] Chronic ischemic diseases of the lower limbs include thromboangiitis obliterans, arteriosclerosis obliterans, and diabetic foot. As the disease progresses, it can lead to microcirculatory disorders and different degrees of distal lower limb ischemic symptoms, such as claudication, rest pain, ischemic ulcers, or gangrene. Such patients have complex physical conditions and many complications. If an ischemic ulcer occurs, the ulcer may not heal, and ulcers and gangrene will increase the risk of systemic infection, or the pain in the affected limb due to ischemia is unbearable, and amputation is ultimately necessary.

[0003] Hinchliffe et al. conducted a systematic review and revealed that osteotomy can indirectly send signals to the body to increase distal perfusion, thereby creating favorable conditions for ulcer healing. In the past, the transverse tibial bone transport technique was often used to treat ischemic ulcers of the lower limbs. Based on the tension-stress principle of Ilizarov, the transverse tibial bone transport technique involves distraction osteogenesis, which often leads to neovascularization of the surrounding tissues. This technique can not only relieve ischemia and pain, but also promote the healing of refractory ulcers and improve the limb salvage rate. It has shown promising results in the treatment of chronic ischemic diseases of the lower limbs. However, major complications include tibial fractures, osteomyelitis and pin site infection, as well as skin necrosis due to the relatively poor vascularity of the anterior tibia.

[0004] The principle of iliac traction technique is similar to that of tibial transverse bone transport technique. Iliac traction technique stimulates the production of angiogenic factors, promotes angiogenesis in newly formed bone, and induces high expression of vascular endothelial growth factor and basic fibroblast growth factor. These systemic reactions lead to the release of various inflammatory mediators, hormones, stem cells, and growth factors. Unlike the tibia, the iliac crest is not weight-bearing and is far away from foot ulcers. In addition, the iliac crest contains abundant cancellous bone and has a rich blood supply, which can reduce the incidence of osteomyelitis. Iliac traction technique can effectively increase distal perfusion, promote ulcer healing, and avoid tibial fractures. After surgery, patients can walk freely, reduce some complications related to bed rest (muscle weakness, pneumonia, urinary tract infection, pressure sores, deep vein thrombosis), and improve the quality of life. In addition, the skin around the anterior superior iliac spine is better vascularized than the anterior tibial skin, reducing the risk of pin site infection and skin necrosis. In conclusion, the iliac crest distraction technique offers several advantages over the lateral tibial bone transport technique, including better blood supply, reduced risk of complications, and improved patient outcomes, making it a superior technique for the treatment of chronic lower extremity ischemic disease.

[0005] As a new treatment technology, iliac distraction technology has been used clinically. However, there is no external fixator specifically used for iliac distraction on the market. The simple external fixator used in clinical practice is large, with thick traction needles, large trauma, and high difficulty in operation, which still brings certain inconveniences to patients' lives. In addition, postoperative distraction generally requires manual distraction of 1 mm per day for 12 days, which is subjective and some patients are prone to mistakes (such as forgetting the number of distraction days and times, etc.), which affects the treatment effect. Therefore, it is necessary to design a portable, automated lateral bone transfer bracket specifically for iliac distraction. Summary of the invention

[0044] When the bone block needs to be raised, the rising stud drives the first permanent magnet to approach the second permanent magnet, and the upper bracket is slowly raised by the repulsive force. The slowly raised magnetic force makes the upper bracket rise more slowly and with uniform force.

[0045] When the bone block needs to be lowered, the descending stud drives the first permanent magnet away from the second permanent magnet, so that the upper bracket slowly descends, which is beneficial to protecting the pulled bone tissue and reducing pain.

[0046] ④ The electromagnetic module is also electrically connected to the timer, the light sensor and the battery module, and the electromagnetic module can be powered by timing, thereby generating a repulsive magnetic force to drive the upper bracket to move upward;

[0070] The automatic lifting component 5 includes a rotating lifting member 501 and an electromagnetic module 502. The rotating lifting member 501 is installed between the upper bracket 2 and the lower bracket 3, and can drive the upper bracket 2 to rise or fall along the height direction of the rotating lifting member 501. A magnet block is provided inside the rotating lifting member 501, and a plurality of electromagnetic modules 502 are spaced around the magnet block of the rotating lifting member 501. The electromagnetic module 502 can attract the rotating lifting member 501 to rotate by changing the magnetic force position.

[0071] The electromagnetic module 502 is also electrically connected to the timer, the light sensor and the battery module.

[0072] The upper bracket 2 is provided with a through hole, and the upper bracket 2 is connected to the rotary lifting member 501 (specifically, to the stud of the rotary lifting member 501) without threading. Specifically, the stud passes through the through hole.

[0073] As a new treatment technique, iliac bone distraction technique is used to make an arc incision of about 5 cm in length on the anterior and lateral side of the anterior superior iliac crest on the affected limb. The skin is cut to the periosteum, the periosteum is cut and peeled off (pay attention to protect the integrity of the periosteum), and the periosteum and skin are sutured to avoid separation. Two vertical osteotomies are made with a bone knife at 2 cm and 7 cm above the upper edge of the anterior superior iliac spine. The tensor fasciae latae and gluteus minimus fibers are split with an electric knife, and the bone is cut transversely on the outer wall to 2 cm deep from the iliac crest. The iliac muscle fibers are cut and the inner bone is cut to form a bone flap of about 5 cm × 1.5 cm to maintain muscle attachment. Two bone traction needles (2.0 mm) are inserted into the middle of the bone flap, and the other two bone traction needles (3 mm) are inserted into the iliac spine 2 cm outside the bone flap, and an external fixator is installed. The wound is cleaned, hemostasis is fully stopped, a drainage tube is left in place, the periosteum, subcutaneous tissue and skin are sutured layer by layer, and the wound is bandaged with sterile dressings. Bone distraction is started on the third day after surgery.

[0074] The bone traction needle 1 is connected to the upper bracket 2, and the lower bracket 3 is connected to the bone fixation needle 8. The automatic lifting component 5 is arranged between the upper bracket 2 and the lower bracket 3. The automatic lifting component 5 can accurately control the traction height of the bone flap driven by the bone traction needle 1, and can be automatically adjusted according to the patient's specific situation and treatment stage, making the treatment process more comfortable and humane; it can also prevent patients from making mistakes (such as forgetting days, times, etc.) affecting the treatment effect.

[0075] Specifically, the bone traction needle 1 and the bone fixation needle 8 have the same appearance, and the same design allows the two needles to be used interchangeably in certain circumstances, thereby enhancing the versatility of medical devices, reducing inventory complexity, and facilitating hospital management and emergency deployment.

[0076] Specifically, the upper bracket 2 and the lower bracket 3 are located in the same plane and are parallel to each other, the photosensor and the timer are turned on, the battery module is connected to the circuit of the electromagnetic module 502, and the electromagnetic modules 502 with an interval ring design are respectively powered to generate a rotating changing magnetic force, and the rotating changing magnetic force attracts the rotating lifting member 501 to drive the bone traction needle 1 connected to the upper bracket 2, and moves along the vertical height direction of the rotating lifting member 501. The bone traction needle 1 fixed to the upper bracket 2 stimulates the regeneration of limb capillaries by stretching the iliac bone block 9, promotes the recruitment of stem cells to damaged tissues, participates in the mediation and reduces the inflammatory response, improves the local microenvironment, facilitates the activation of local stem cells, and accelerates tissue repair, thereby achieving the purpose of improving blood supply to the lower limbs and promoting wound healing; it also ensures that the electromagnetic module 502 works according to a preset time sequence, realizes fine control of the rotating lifting member 501, and ensures the accuracy and safety of treatment.

[0077] As a specific implementation, a placement groove 301 is provided in the middle of the lower bracket 3, the magnet block portion of the rotary lifting member 501 is arranged in the placement groove 301, and the top of the rotary lifting member 501 is connected to the upper bracket 2 through a slow lifting component 6;

[0078] A screw cover 7 is detachably connected to the top of the slow-lift component 6 , and the screw cover 7 is used to prevent the upper bracket 2 from falling off the rotating lifting member 501 .

[0079] Specifically, the rotary lifting member 501 includes a stud and a nut, and the stud and the nut are movably connected by a thread. When working, the nut rotates, thereby driving the stud to move up and down. The nut is provided with a spacer magnet block and can be rotatably set in the placement groove 301. The lower bracket 3 is provided with a coaxial through hole connected to the placement groove 301. The stud moves through the upper bracket 2 and synchronously threads the through hole and the nut; when working, the electromagnetic module 502 is used to drive the nut to rotate to make the stud rise, so that the upper bracket 2 connected to the top drives the bone traction needle 1 to rise.

[0080] Specifically, a magnet block is arranged on the nut of the rotary lifting member 501, and a plurality of electromagnetic modules 502 are arranged around the magnet block; the stud is threadedly connected to the upper bracket 2 and passes through the top thereof, and a tightening screw cover 7 is also arranged on the top to prevent it from loosening;

[0081] When working, the battery module supplies power to a plurality of electromagnetic modules 502 at intervals to generate a rotating magnetic force outside the magnet block of the rotating lifting member 501, so that the nut rotates to drive the stud to rise or fall; and the upper bracket 2 connected to the top drives the bone traction needle 1 to rise or fall;

[0082] When the bone block needs to be raised, the battery module generates a positive rotating magnetic force outside the magnet block through positive power supply, so that the nut rotates to drive the stud to rise, and the upper bracket 2 connected to the top drives the bone traction needle 1 to rise, ensuring the smooth transmission of force and the precise application of traction force;

[0083] When the bone block needs to be lowered, the battery module generates reverse rotating magnetic force on the outside of the magnet block through reverse power supply, so that the nut rotates to drive the stud to descend, and the upper bracket 2 connected to the top drives the bone traction needle 1 to descend, thereby greatly improving the accuracy, comfort and convenience of bone traction treatment, which is a manifestation of the progress of modern orthopedic treatment technology.

[0084] As a specific embodiment, the slow-lift component 6 includes a first permanent magnet 601 and a second permanent magnet 602; the first permanent magnet 601 is fixedly arranged on the rotating lifting component 501 and rises or falls as the rotating lifting component 501 rotates, and the second permanent magnet 602 is installed on the upper bracket 2 and rises or falls as the first permanent magnet 601 approaches.

[0085] Specifically, a first permanent magnet 601 is fixed on the stud of the rotating lifting member 501, and a second permanent magnet 602 is installed at the bottom of the upper bracket 2 and arranged on the top of the first permanent magnet 601 with the same polar surface corresponding to the first permanent magnet 601. The electromagnetic module 502 is used to drive the nut to rotate to make the stud rise or fall.

[0086] Since the upper bracket 2 is connected to the rotating lifting member 501 (specifically, the stud of the rotating lifting member 501) without threaded connection, during operation, the electromagnetic module 502 drives the rotating lifting member 501 to drive the first permanent magnet 601 to move up and down, the first permanent magnet 601 drives the second permanent magnet 602 to move up and down, and the second permanent magnet 602 drives the upper bracket 2 to drive the bone traction needle 1 to move up and down to complete bone traction.

[0087] When the bone block needs to be raised, the rising stud drives the first permanent magnet 601 to approach the second permanent magnet 602, and the upper bracket 2 is slowly raised by the repulsive force. The slowly raised magnetic force makes the upper bracket 2 rise more slowly and with uniform force.

[0088] When the bone block needs to be lowered, the descending stud drives the first permanent magnet 601 away from the second permanent magnet 602, so that the upper bracket 2 slowly descends, which is beneficial to protecting the pulled bone tissue and reducing pain.

[0089] As a specific implementation method, the needle heads of the bone traction needle 1 and the bone fixation needle 8 are self-tapping screw heads; since the bone traction needle 1 and the bone fixation needle 8 with self-tapping screw heads can effectively cut and grasp the bone when entering the bone, there is no need for pre-drilling, which reduces the surgical steps and makes the operation faster. At the same time, it ensures that the needle body is firmly fixed and not easy to slip.

[0090] Specifically, bone distraction began on the third day after surgery, with 1 mm of movement per day, which was completed in 4 times on average. X-rays were reviewed one week after movement to determine the position of the bone block, and the bone block was maintained for 3 days after the movement distance reached 12 mm; then the bone block was moved back at the same speed until it returned to its original position, and the X-rays were reviewed to determine and adjust the position of the bone block; the bone movement bracket was removed after 5 days of maintenance.

[0099] Specifically, the number of the first insertion holes 202 of the upper bracket 2 and the second insertion holes 303 of the lower bracket 3 are both two and parallel to each other, that is, the two bone traction pins 1 and the bone fixation pins 8 are parallel to each other, which is convenient for positioning after being inserted into the cut.

When the bone traction pin 1 passes through the first mounting hole 201 and the through hole, the connecting bolt 402 is tightened, that is, the connecting bolt 402 is used to push the bone traction pin 1 to fit and abut against the arc groove edge of the through hole to prevent the bone traction pin 1 from falling out of the first insertion hole 202. Specifically, the bone fixation pin 8 is fixed to the lower bracket 3 in the above manner.

[0103] As a specific implementation, the timer is installed inside the lower support 3; the photosensor is installed outside the lower support 3 to sense light; the battery module is installed inside the lower support 3;

[0104] The photosensor is installed on the outer side of the lower bracket 3 to ensure that the light can directly irradiate the sensing area.

[0105] Example 3

[0106] like Figure 1-8 As shown, Figure 1-8As shown, this embodiment discloses a transverse bone transport bracket for ilium, comprising: a bone traction pin 1, an upper bracket 2, a lower bracket 3, a rotation adjustment component 4, an automatic lifting component 5 and a slow lifting component 6, the bone traction pin 1 is connected to the upper bracket 2 through the rotation adjustment component 4, the lower bracket 3 is connected to the bone fixation pin 8, the upper bracket 2 is connected to the lower bracket 3 through the automatic lifting component 5, and a slow lifting component 6 is provided between the upper bracket 2 and the lower bracket 3;

[0107] The automatic lifting component 5 includes a rotating lifting member 501 and an electromagnetic module 502. The rotating lifting member 501 is installed between the upper bracket 2 and the lower bracket 3, and can drive the upper bracket 2 to rise or fall along the height direction of the rotating lifting member 501. A magnet block is provided inside the rotating lifting member 501, and a plurality of electromagnetic modules 502 are spaced around the magnet block of the rotating lifting member 501. The electromagnetic module 502 can attract the rotating lifting member 501 to rotate by changing the magnetic force position.

[0108] The electromagnetic module 502 is also electrically connected to the timer, the light sensor and the battery module.

[0109] As a specific implementation manner, there is a threaded connection between the upper bracket 2 and the rotating lifting member 501; specifically, the upper bracket 2 and the stud of the rotating lifting member 501 are threadedly connected and fixedly connected, and do not move relative to each other during operation.

[0110] The rotary lifting member 501 comprises a stud and a nut, and the stud and the nut are fixedly connected. When working, the nut and the stud have no relative movement.

[0111] During operation, the electromagnetic module 502 drives the rotary lifting member 501 to move up and down, and the screw of the rotary lifting member 501 drives the upper bracket 2 and the first permanent magnet 601 to move up and down to complete bone traction. The lifting of the first permanent magnet 601 can also make the movement of the upper bracket 2 smoother and more uniform through repulsion, which is beneficial to protect the pulled bone tissue and reduce pain.

[0112] Example 4

[0113] like Figure 1-8 As shown, this embodiment discloses a method for using a transverse bone transport bracket for an ilium, comprising:

[0114] S1: insert the bone traction needle 1 into the middle of the bone flap, insert a bone traction fixation needle 1 at both ends of the ilium 2 cm away from the bone flap, then install the lower bracket 3 outside the bone traction needle 1 and the bone fixation needle 8, then connect the upper bracket 2 to the lower bracket 3 through the automatic lifting component 5 and the slow lifting component 6, and finally adjust the angles of the bone traction needle 1 and the bone fixation needle 8 to the upper bracket 2 and the lower bracket 3 respectively through the rotation adjustment component 4 and then fix them;

[0115] S2: When bone distraction is required, the battery module is turned on to power different electromagnetic modules 502 in sequence, and the power supply time is set on the timer. The bone is moved by distraction by 1 mm every day, and it is completed in 4 times on average. After 1 week of movement, the X-ray film is checked again to determine the position of the bone block. When the movement distance reaches 12 mm, it is maintained for 3 days; then the bone is moved back at the same speed until it returns to the original position;

[0116] S3: At night, the light sensor is turned off, the battery module and the electromagnetic module 502 are powered off, and the electromagnetic module 502 with an interval ring design loses power and does not generate magnetic force;

[0117] S4: During the day, the light sensor and the timer are turned on, the battery module is connected to the circuit of the electromagnetic module 502, and the electromagnetic modules 502 with an interval ring design are powered to generate a rotating variable magnetic force, which attracts the rotating lifting member 501 to drive the bone traction needle 1 connected to the upper bracket 2 to rise or fall;

[0118] S5: When the power supply time of the timer ends, the next power supply time of the timer is started, the battery module and the electromagnetic module 502 are powered off, the electromagnetic modules 502 with an interval ring design are powered off and do not generate magnetic force, and the rotating lifting component 501 stops driving the bone traction needle 1 connected to the upper bracket 2 to rise or fall.

[0119] Specifically, the diameter of the bone traction fixation needle 1 is 2 mm. When performing bone traction, the bone traction fixation needle 1 with a diameter of 2 mm can reduce the trauma of the puncture point, reduce damage to the bones and surrounding soft tissues, reduce the risk of infection, and is more easily accepted by the bones and tissues, thereby reducing the postoperative recovery time.

[0120] Specifically, the electromagnetic module 502 is electrically connected to the battery module through a timer and a photosensor, the photosensor and the timer are turned on, the circuits of the battery module and the electromagnetic module 502 are connected, and the electromagnetic modules 502 with an interval ring design are energized to generate a rotating changing magnetic force. The rotating changing magnetic force attracts the rotating lifting component 501 to drive the bone traction needle 1 connected to the upper bracket 2 to rise or fall, ensuring that the electromagnetic module 502 works according to a preset time sequence, achieving fine control of the rotating lifting component 501, and ensuring the accuracy and safety of treatment.

[0121] In addition, the patented ICBD surgery has another advantage over conventional tibial transverse transport technology, which is that ICBD surgery does not require waiting for bone healing, and can be removed after the bone fragment returns to its original position for 5 days. Conventional tibial transverse bone transport stents generally need to wait for fracture healing (generally, the bone fragment returns to its original position and is fixed for another 2 months) before the stent is removed. ICBD surgery reduces the time patients spend wearing external fixators, reduces the impact of carrying external fixators on patients' daily lives, and effectively shortens the patient's treatment cycle.

[0122] How it works

[0123] The bone traction needle 1 is connected to the upper bracket 2, the lower bracket 3 is connected to the bone fixation needle 8, and the automatic lifting component 5 is set between the upper bracket 2 and the lower bracket 3. The automatic lifting component 5 can accurately control the traction height of the bone flap driven by the bone traction needle 1, and can be automatically adjusted according to the patient's specific situation and treatment stage, making the treatment process more comfortable and humane; it can also prevent patients from making mistakes (such as forgetting days, times, etc.) that affect the treatment effect.

[0124] During operation, the photosensor and the timer are turned on, the battery module is connected to the circuit of the electromagnetic module 502, and the electromagnetic modules 502 with an interval ring design are energized to generate a rotating variable magnetic force. The rotating variable magnetic force attracts the rotating lifting component 501 to drive the bone traction needle 1 connected to the upper bracket 2, and moves along the vertical height direction of the rotating lifting component 501. The bone traction needle 1 fixed to the upper bracket 2 stimulates the regeneration of limb capillaries by lifting or pressing down the patient's ilium 9, promotes the recruitment of stem cells to damaged tissues, participates in the mediation and reduces inflammatory reactions, improves the local microenvironment, facilitates the activation of local stem cells, and accelerates tissue repair, thereby achieving the purpose of improving blood circulation in the lower limbs and promoting wound healing; it also ensures that the electromagnetic module 502 works according to the preset time sequence, realizes the fine control of the rotating lifting component 501, and ensures the accuracy and safety of treatment.
