Description

Technical Field

[0001] The invention relates to the technical field of surgical medical instruments, in particular to a temporary local fixation device for fracture patients used in surgical emergency. Background Art

[0002] The existing emergency surgery department or emergency medicine center is the department in the hospital with the most diseases and the heaviest rescue and management tasks. It is the only way for all emergency patients to be admitted to the hospital for treatment. In the emergency surgery department, for patients with broken lower legs, since they cannot walk due to broken lower legs, and cannot sit in a wheelchair before plaster and treatment (the lower leg will be under stress), the patient's leg must be temporarily fixed first to facilitate the patient to take X-rays of the broken arm and other examinations and transfers in the hospital, and to facilitate the doctor to plan the treatment of the patient's leg.

[0003] 1. Traditional local temporary fixation devices for calf fractures generally use screw adjustment to achieve tightening between clamps, and the clamps are generally distributed in multiple groups and have the same size. However, the thickness of human calves is not completely the same. Therefore, when clamps of the same size are used to fix the patient's calf, the upper part of the calf may be fixed but the lower part of the calf cannot be fixed, and the full clamping effect cannot be achieved. There are great limitations. In addition, the human calf is generally conical, that is, thick at the top and thin at the bottom. It requires a strong clamping force to achieve the stability of the device only by the clamping effect of the clamp, which will cause great pain to the patient and may also cause secondary damage to the fracture site.

[0004] Therefore, the first direction of the present invention is to maximize the reduction of damage to the patient while improving the stability of the clamp.

[0005] 2. As we all know, patients with calf fractures have great inconvenience in life. They can only lie in bed and move their thighs slowly. However, clinicians usually force rehabilitation patients to move their calves more (bend their knees) to prevent calf muscle atrophy and knee damage caused by lying flat for a long time. Normally, human knee flexion is formed by the combination of two actions, namely, lifting the thigh and retracting the calf. For rehabilitation patients with calf fractures, lifting the thigh is no problem, but retracting the calf requires the autonomous force of the calf muscles, which will cause unbearable pain at the fracture site.

[0006] Therefore, a second aspect of the present invention is to use a fixation device to assist patients recovering from a lower leg fracture to perform knee flexion exercises with less pain.

[0007] In view of the above problems, it is urgently necessary to make innovative designs based on the original temporary local fixation devices for fracture patients used in surgical emergencies. Summary of the invention

[0008] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a temporary local fixation device for fracture patients for surgical emergency treatment, so as to solve the problem proposed in the above background technology that people's calves are not completely the same in thickness. Therefore, when clamps of the same size are used to fix the patient's calves, the upper half of the calf may be fixed but the lower half of the calf cannot be fixed, and a comprehensive clamping effect cannot be achieved, which has great limitations.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a temporary local fixation device for fracture patients for surgical emergency treatment, comprising a first frame and a second frame, wherein a first rotating shaft is symmetrically hinged between the two ends of the first frame, and a rotating rod is provided at one end of the first frame through a bearing, a control component is installed at one end of the rotating rod for synchronously controlling the two groups of first rotating shafts, and the other end of the rotating rod is fixedly connected to one end of a connector, and the other end of the connector is fixedly connected to a screw rod.

[0010] Preferably, the screw rod is installed inside the second frame, and the second rotating shaft is symmetrically installed inside the second frame, and the outer wall of the second rotating shaft is fixed with a clamping plate for clamping at the root of the thigh to achieve locking.

[0011] Preferably, a threaded block is slidably provided on the outer wall of the screw rod, and a screw hole matching the thread of the outer wall of the screw rod is provided inside the threaded block, and the threaded block is respectively fitted to the two second rotating shafts.

[0012] Preferably, the outer wall of the second rotating shaft is provided with a second guide rail, and one end of a second protrusion is slidably arranged inside the second guide rail, and the other end of the second protrusion is fixed to the outer wall of the threaded block, and the second guide rail is arranged in an arc shape on the outer wall of the second rotating shaft.

[0013] Preferably, the control component includes a slider, a first protrusion, a first guide rail, a slide groove and an adjusting rod, and the outer wall of the rotating rod is sleeved with a slider, a screw hole matching the thread of the outer wall of the rotating rod is provided inside the slider, and a first guide rail is provided on the outer wall of the first rotating shaft, one end of the first protrusion is slidably provided inside the first guide rail, and the other end of the first protrusion is fixed to the outer wall of the slider side, a slide groove is provided at the end of the rotating rod away from the connector, and the end of the adjusting rod is slidably provided inside the slide groove, the other end of the adjusting rod is penetrated and installed on the outside of the first frame, and a screw hole matching the thread of the outer wall of the adjusting rod is provided inside the first frame.

[0014] Preferably, the first protrusions are symmetrically arranged at the centers of both sides of the slider, and the first guide rail is arranged in an arc shape. A splint is fixed to the outer wall of the first rotating shaft, and the first rotating shaft and the splint are symmetrically arranged about the central axis of the rotating rod. The splints are distributed in four groups with decreasing radius and at equal intervals on the outer wall of the first rotating shaft, and the radius of the splints adjacent to the adjusting rod reaches the lowest value.

[0015] Preferably, a regular hexagonal structure is provided at the inner end of the adjusting rod, and the adjusting rod forms a snap-fit ​​sliding structure with the rotating rod through a sliding groove.

[0016] Preferably, a base is provided under the first frame body, and a groove is provided on the upper surface of the base, and a fixing rod is fixed inside the base, and the outer walls of the fixing rod are respectively sleeved with a limit block and a spring, and one end of the spring is welded to the outer wall of the limit block, and the other end of the spring is fixed to the inner wall of the groove, the upper ends of the limit blocks are respectively hinged with a first support plate and a second support plate, and the first support plate and the second support plate are respectively hinged to the second frame body and the lower surfaces of the first frame body, the side of the second support plate is hinged with the telescopic end of the damper, and the bottom end of the damper is hinged to the upper surface of the base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Four groups of symmetrically arranged splints are distributed in a manner that the radius of the clamp gradually decreases from top to bottom along the calf, which can fit the patient's leg muscles well and effectively avoid the occurrence of clamping gaps at the lower end of the calf. At the same time, a group of symmetrically arranged thigh clamps are connected through a connector that can rotate and transmit in multiple directions (the existing transmission structure is not described in this article), which can not only be opened and tightened by the rotation adjustment of the adjustment rod, but also be engaged at the lower end of the patient's thigh to achieve locking of the calf clamp (the reason why the calf clamp can be locked is that when a person lies flat, the upper surface of the thigh and calf can be understood as an oblique line, but the knee is protruding, so that the calf clamp is synchronously locked by blocking the two clamps with the knee, avoiding horizontal deviation of the calf clamp), which minimizes the harm to the patient while effectively improving the stability of the clamp;

[0019] When the adjusting rod is rotated, the sliding groove inside the rotating rod is used to offset the horizontal position of the adjusting rod, and then the rotation of the adjusting rod drives the first screw rod to rotate and realize the horizontal sliding of the slider, so that the two groups of first protrusions slide synchronously and squeeze the two groups of first guide rails, and then the two groups of first rotating shafts can synchronously perform adaptive symmetrical rotation to adjust the fixture spacing;

[0020] 2. As mentioned above, a calf clamp structure is provided on the first frame, a stabilizing structure is provided on the second frame, and the first frame and the second frame are connected by a multi-directionally rotatable connector, so that the patient's normal knee flexion movement will not be affected. At the same time, two sets of support plates that can rotate in both directions are hinged by a limit block that can only slide horizontally. When the patient attempts to flex his knee normally, the thigh first exerts force to pull the limit block horizontally to the left through the first support plate. When the limit block slides horizontally to the left, it will simultaneously generate an oblique pulling force on the second support plate. Therefore, when the thigh is lifted, the device will autonomously generate a pulling force on the calf to move closer to the thigh, thereby realizing that the thigh drives the calf to assist in knee flexion and reduces the degree of autonomous force of the calf.

[0030] See also Figure 1-7 The present invention provides a technical solution: a temporary local fixation device for fracture patients for surgical emergency treatment, comprising a first frame 1 and a second frame 11, wherein a first rotating shaft 2 is symmetrically hinged between the two ends of the first frame 1, and a rotating rod 4 is provided at one end of the first frame 1 through a bearing, a control component is installed at one end of the rotating rod 4 for synchronously controlling the two groups of first rotating shafts 2, and the other end of the rotating rod 4 is fixedly connected to one end of a connector 10, and the other end of the connector 10 is fixedly connected to a screw rod 14.

[0032] A threaded block 15 is slidably provided on the outer wall of the screw rod 14, and a screw hole matching the thread of the outer wall of the screw rod 14 is opened inside the threaded block 15, and the threaded block 15 is respectively attached to the two second rotating shafts 12.

[0035] The first protrusions 6 are symmetrically arranged at the centers of both sides of the slider 5, and the first guide rails 7 are arranged in an arc shape. A splint 3 is fixed to the outer wall of the first rotating shaft 2, and the first rotating shaft 2 and the splint 3 are symmetrically arranged about the central axis of the rotating rod 4. There are four groups of splints 3 distributed at equal intervals in a decreasing radius on the outer wall of the first rotating shaft 2, and the radius of the splints 3 adjacent to the adjusting rod 9 reaches the minimum value. The splints 3 distributed at equal intervals in a decreasing radius can achieve the maximum wrapping of the patient's calf, avoid clamping gaps, and also reduce the patient's discomfort.

[0036] The inner end of the adjusting rod 9 is provided with a regular hexagonal structure, and the adjusting rod 9 forms a snap-fit ​​sliding structure with the rotating rod 4 through the slide groove 8, ensuring that when the adjusting rod 9 rotates and slides horizontally, the adjusting rod 9 will slide along the inside of the slide groove 8 while driving the rotating rod 4 to rotate through the slide groove 8, and the thread between the adjusting rod 9 and the first frame 1 has a certain self-locking function, which can realize the locking of the whole.

[0037] A base 18 is provided below the first frame body 1, and a groove is provided on the upper surface of the base 18, and a fixing rod 19 is fixed inside the base 18, and the outer wall of the fixing rod 19 is respectively sleeved with a limit block 20 and a spring 21, and one end of the spring 21 is welded to the outer wall of the limit block 20, and the other end of the spring 21 is fixed to the inner wall of the groove, and the upper end of the limit block 20 is respectively hinged with a first support plate 22 and a second support plate 23, and the first support plate 22 and the second support plate 23 are respectively hinged to the lower surfaces of the second frame body 11 and the first frame body 1, and the side of the second support plate 23 is hinged with the telescopic end of the damper 24, and the bottom end of the damper 24 is hinged to the upper surface of the base 18.

[0038] Working principle: When using this surgical emergency fracture patient temporary local fixation device, first Figure 1 , Figure 4 and Figure 5 As shown, the fixing device is placed under the leg of the patient with a calf fracture, and then the two groups of clamping plates 13 are fitted on the lower end of the thigh, and the four groups of splints 3 symmetrically distributed in sequence are fitted on the patient's calf, and then the adjusting rod 9 is rotated clockwise, and the adjusting rod 9 rotates clockwise and slides toward the inside of the first frame 1. At this time, the inner end of the adjusting rod 9 will slide along the inner wall of the slide groove 8 in a clamping manner and synchronously drive the rotating rod 4 to rotate clockwise synchronously through the inner wall of the slide groove 8. At the same time, the clockwise rotating rotating rod 4 will drive the slider 5 to slide horizontally to the right under the action of the thread, so that the two groups of first protrusions 6 synchronously squeeze the inner walls of the two groups of first guide rails 7, thereby making the two groups of first rotating shafts 2 synchronously and symmetrically rotate adaptively and making the corresponding two groups of splints 3 gradually approach and gradually wrap and fix the patient's calf.

[0039] At the same time, the rotating rod 4 synchronously drives the screw rod 14 to rotate clockwise through the connector 10. When the screw rod 14 rotates clockwise, under the action of the outer wall thread of the screw rod 14 and the fitting limit action of the two groups of second rotating shafts 12, the threaded block 15 will slide horizontally to the left along the outer wall of the screw rod 14 and drive the two groups of second protrusions 16 to squeeze the inner walls of the two groups of second guide rails 17, thereby making the two groups of second rotating shafts 12 synchronously and adaptively rotate symmetrically and making the two groups of clamping plates 13 gradually rotate close to and tighten at the lower end of the patient's thigh (near the knee). With the tightening of the two groups of clamping plates 13 and the eight groups of splints 3, the patient's calf is fixedly clamped (the reason why the calf clamp can be locked is that when a person lies flat, the upper surface of the thigh and calf can be understood as an oblique line, but the knee is protruding, so that the calf clamp is synchronously locked by blocking the two clamping plates 13 with the knee, avoiding horizontal displacement of the calf clamp), maximizing the reduction of damage to the patient while effectively improving the stability of the clamp.

[0040] like Figure 1 As shown, when the patient attempts to flex the knee normally, the thigh first exerts force through the first support plate 22 to pull the limit block 20 horizontally to the left. When the limit block 20 slides horizontally to the left, it will simultaneously generate an oblique pulling force on the second support plate 23. Therefore, while the thigh is lifted, the device will autonomously generate a pulling force on the calf to move closer to the thigh, thereby achieving the thigh driving the calf to assist in flexing the knee, reducing the degree of autonomous force of the calf, and when the calf needs to be lowered, the resetting cooperation between the spring 21 and the damper 24 will enable the calf clamp to be lowered with the patient's calf in a gentle posture to avoid damage to the patient's fracture.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
