Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular is a trauma fracture fixation device capable of improving the fixation effect of patients. Background Art

[0002] The rapid development of modern industry, construction, transportation and other fields has made high-energy injuries more common, and various emergency traumas have increased rapidly. In the past, on-site first aid was generally carried out by carrying, pulling, dragging, lifting and moving. Due to the lack of equipment or improper rescue, the trauma was often more serious, resulting in secondary injuries at the fracture site. At present, traditional fracture fixation methods are mostly used. Patients with rib fractures are fixed with rib fixation belts, patients with lumbar fractures are fixed with waist belts, and patients with limb fractures (or injured persons) are fixed with limb splints, pads, and cable ties. The extremities are exposed, and then the patients are moved to the hard stretcher for transportation through the correct method. Patients with thoracic and lumbar fractures require three people to complete the transportation. The three people hold the shoulder, back, waist, buttocks and lower limbs on the right side of the patient, and under unified command, move the patient on or off the hard stretcher together.

[0003] When patients suffer high-energy violent injuries, they are often accompanied by severe bleeding and complex complications. In some special occasions, such as major traffic accidents, there is a lack of equipment for on-site first aid, and it is difficult to stop bleeding and carry the patient, which greatly increases the chance of secondary injury. Therefore, there is an urgent need for a simple, effective and standardized external fixation device and instrument that can be widely used in traumatic fractures of the limbs, spine, pelvis and other parts. The affected limb can be effectively immobilized to avoid secondary injuries, so that patients can receive safe and effective treatment at the pre-hospital first aid site and in the hospital. In addition, during use, the above-mentioned device is simple, rapid, non-invasive and effective to operate. Users do not need to undergo special training, and can quickly restore the stability of the cervical, lumbar and pelvic rings, reduce abnormal activities of the fracture ends, and achieve the effect of controlling the bleeding of important vascular injuries in the fracture, thereby facilitating the safe transportation and anti-shock treatment of patients and improving the success rate of rescue.

[0059] First embodiment:

[0060] Place Figure 1-2 As shown, the trauma fracture fixation device of this embodiment has the advantages of improving the fixation effect of patients, and is characterized by:

[0061] The fixing device includes an outer frame and an inner frame, both of which are rectangular, and the long sides of the rectangular outer frame and inner frame are called sides, and the short sides are called ends; the ends of the outer frame are provided with crossbeams and handles extending outward and exceeding the crossbeams; the ends of the inner frame are assembled and connected to the crossbeams of the ends of the outer frame at corresponding positions, and a gap is left between the sides of the inner frame and the sides of the outer frame; the inner frame is provided with a bearing surface, which is arranged inside the inner frame, the bearing surface is rectangular, and its edge coincides with the contour of the inner frame, and the edge of the bearing surface is fixedly connected to the inner frame; the main parts and direct contact parts of the inner frame and the bearing surface that carry the patient, the outer frame is used to provide a support frame for the inner frame, and provide a support platform for other devices such as clamping devices, isolation tents, etc. Further, the outer frame can also be equipped with long or short feet, casters, legs and other structures to enable the fixing device to be lifted to a certain height from the ground.

[0062] The fixing device is provided with a clamping device, which is arranged above the bearing surface, and is used for clamping and fixing the fracture site of the patient placed on the bearing surface; the above-mentioned clamping device is arranged above the bearing surface, which means that the clamping device is on the upper part of the bearing surface, and there may be a gap between the clamping device and the bearing surface, and the clamping device may be in a suspended state, or the clamping device may be fixed to the bearing surface directly or through an extension component.

[0063] The fixing device is provided with at least one set of clamping devices, which are used to clamp and fix one or any several of the fracture traumas including but not limited to the limbs, spine, and pelvic parts; the clamping devices are assembled on the end of the inner frame, or the end of the outer frame, or the bearing surface through a connecting piece. Generally speaking, patients usually suffer from a single fracture trauma, and it is rare for multiple fractures to occur at the same time. Therefore, the fixing device is generally equipped with a set of clamping devices to fix the corresponding fracture site; when multiple fractures occur, corresponding multiple clamping devices can be assembled according to the different fracture sites, so as to fix multiple fracture sites at the same time. In addition, for traumas at different fracture sites, the clamping devices used should be different. For example, for fractures in the pelvic area, the clamping device used and the clamping device for fractures of the limbs, especially the lower limbs, will have different structures, especially in terms of size specifications, shape contours, etc., and the differences are obvious. However, for the invention, the clamping device has the same working principle, which is a hard outer plate inner wall with a contoured profile, and an inflatable cushion layer is provided. After the hard outer plate is buckled on the fracture site and adjusted to a certain position, the tightness between the fracture site and the clamping device is further adjusted by the inflation degree of the inflatable cushion layer, so as to achieve flexible fixation of irregularly shaped fracture sites, so that the fixation effect is better, and the impact of external fixation on the patient's body function is further reduced. Based on the above principles, in the following description, only the fixation of limbs, especially lower limb fracture trauma, is used as an example to describe in detail the specific structure of the clamping device and its related components. The clamping devices applicable to other fracture sites can be implemented by reference.

[0064] The connecting member includes but is not limited to any one of a support frame, a support rod, and a support plate. The connecting member and the inner frame end, or the outer frame end, or the bearing surface are connected by any one of the methods including but not limited to welding, riveting, clamp connection, bolt connection, and hinged connection. When the clamping device is assembled on the bearing surface, the connecting member used to assemble and connect the clamping device and the bearing surface is a sewn connecting line. As can be seen from the above description, a high-level general concept in the connecting member refers to an existing conventional component that can realize the assembly connection between the clamping device and the inner frame end, or the outer frame end, or the bearing surface. It can adopt any existing known public technology, which will not be repeated here.

[0067] The clamping device comprises a splint, a rotating rod, a distance adjusting part and a buckle; the splint is a pair of long arc-shaped hard plates with arc surfaces arranged opposite to each other, and the clamp can be buckled on the fracture site of the patient to clamp the fracture site; the rotating rod is a long rod-shaped component, and there are two rotating rods, which are respectively arranged at the middle position of the outer side of a pair of splints, and the rotating rod is fixedly connected to the splints;

[0068] The distance adjusting part includes a sliding rod, a support rod, and a pulling rod; the sliding rod is fixedly connected to a connecting piece, and the connecting piece is used for the assembly connection between the clamping device and the end of the outer frame; the sliding rod is hinged to one end of the support rod at one end close to the splint, and the support rod has two, and the other end of the support rod is hinged to the rotating rod; a sliding block and a rack are provided at the end of the sliding rod away from the splint, the sliding block can slide freely on the sliding rod, the rack is provided on the sliding rod, and a locking button is provided between the sliding block and the rack; the locking button can adopt any existing known public technology, such as a pawl in a ratchet structure, or a button with a spring based on the same principle, which will not be repeated.

[0069] The buckle is provided with a splint at one end away from the distance adjustment part, and the buckle is used to limit the gap between the two arc-shaped hard plates at one end of the splint away from the distance adjustment part. The buckle can adopt any existing known public technology, and its function is to limit the gap between a pair of splints after locking, so that the splints will not be separated from the patient's fracture site; when the buckle is opened, the gap between the splints can be adjusted, and the two splints can be opened to remove or install the clamping device. The buckle can be directly implemented by existing technology, and it will not be repeated here.

[0070] The connecting member includes a support and a sleeve. The sleeve is sleeved on the beam at the end of the outer frame. The sleeve can slide freely along the axial direction of the beam and rotate around the beam. One end of the support is fixedly connected to the sleeve, and the other end is fixedly connected to the sliding rod of the distance adjustment part.

[0071] Place Figure 4 As shown, the clamping device is provided with two groups, and the two groups of clamping devices are arranged in parallel on the crossbeam at the end of the outer frame, and are used to fix the fractures of both lower limbs at the same time.

[0074] The above-mentioned different pad areas correspond to different body positions of the patient. The splint is used to limit the basic position of the clamping device. The hard inner plate and the soft pad layer are used to directly contact the patient's body surface, which will not cause mechanical damage to the body surface, and can enable the hard inner plate to clamp the fracture site more directly, thereby avoiding the flexible airbag from causing dislocation and compression of the fracture site, or other unreasonable extrusion; the airbag flexibly adjusts the distance between the hard inner plate and the splint, and through the characteristics of the airbag, makes the inner plate fit the patient's fracture site more closely.

[0075] In addition, the air cushion on the splint is divided into multiple pad areas, and the adjustment of the airbags in each pad area is independent, so that the tightness of the fracture site, especially the lower limb fracture site, can be adjusted more reasonably, the fracture site can be effectively fixed, and through the adjustment of different pad areas, different parts of the lower limbs can be compressed to different degrees to prevent the occurrence of other body symptoms.

[0076] The air cells in the cushion area are arranged in an aligned or staggered manner.
