Description

External protection device of pelvic unlocking and reduction bracket

Technical Field

The invention relates to the technical field of protective devices, and in particular to an external protective device of a pelvic unlocking and resetting bracket.

Background technique

With the rapid development of modern society, the incidence of pelvic fractures has increased year by year. Pelvic fractures have a high disability rate (37%) and a high mortality rate (30-60%). Traditional surgery is very traumatic and critically ill patients cannot bear it. Minimally invasive surgery for pelvic fractures has the advantages of less trauma and faster recovery, but fracture reduction is difficult. Complications of minimally invasive surgery such as nerve damage and poor limb function are all related to poor fracture reduction.

At present, pelvic reduction brackets are mostly used for treatment of pelvic fractures. As shown in FIG1 , the reduction bracket is composed of many metal brackets, joints and metal screws. The metal screws are inserted into the pelvis for fixation, reducing the activity of the fracture site and stabilizing the entire pelvis. The advantages of fixation by the reduction bracket are small surgical trauma, multiple fractures can be fixed at the same time, and it is easy to remove after the fracture heals. However, during the recovery process of the pelvic reduction bracket fixation, a large amount of gauze needs to be placed under the reduction bracket to separate the patient from the bed. Since the patient needs to lie on the bed for a long time during the recovery period, the gauze will be pressed tightly. At the same time, when the patient turns over during the use of this type of reduction bracket, the metal bracket of the reduction bracket will hit the trunk, causing skin rupture. Therefore, although the current recovery effect of the reduction bracket is good, the patient's experience during use is relatively poor.

Summary of the invention

In this regard, the present invention aims to provide an external protective device for a pelvic unlocking and reduction bracket. By using this external protective device, a buffer can be formed between the patient and the reduction bracket, and it is beneficial for the patient to turn over, thereby improving the use effect.

In this embodiment, an inner bag 19 is further provided on the inner side of the inflatable cushion between the left protection module 1 and the right protection module 2. In this way, in actual use, since the patient will be in a supine position for a long time, a material with a certain elasticity such as silicone can be added to the inner bag 19 to improve comfort.

In this embodiment, the inflatable cushion is provided with an inflation port 20, and a cover is provided on the inflation port 20. The inflation port is also connected to an inflation tube, and the inflation tube is connected to an airbag ball. The airbag ball adopts the structure of a sphygmomanometer. The inflation port is pressed and inflated by the airbag ball, thereby playing a role of inflating the inflatable cushion. The structure is simple and inflation is more convenient. Of course, an electric air pump can also be used for inflation.

In this embodiment, the inflation port 20 is a tubular structure, and an annular groove 21 is provided on the inner wall of the inflation port 20. An elastic sealing ring 28 is embedded in the annular groove 21. When the cover is inserted into the elastic sealing ring 29, the elastic sealing ring 29 can be squeezed to deform and fill the annular groove 21, thereby ensuring the sealing between the annular groove 21 and the cover and reducing air leakage.

In this embodiment, the cover includes a circular cover body 29, a connecting boss 30 is connected to the cover body, and two inclined sealing sheets 31 are arranged on the connecting boss 30 at intervals. After the cover is closed, the elastic sealing ring 29 can press the sealing sheet 31 to make it close to the wall of the connecting boss 30, thereby enhancing the sealing between the elastic sealing ring 29 and the connecting boss 30, thereby ensuring the overall sealing effect, making the device more reliable.

In this embodiment, guide grooves are provided on the inner sides of the left protection module 1 and the right protection module 2 for inserting the other end of the lateral adjustment component 7, so that the lateral adjustment component 7 can be limited and its moving direction can be guided.

In this embodiment, in actual use, the method of fixing the inflatable cushion by Velcro may be inconvenient to remove. When removing, due to the large area of Velcro, medical personnel need to tear it open with force, which will cause the patient to make large movements. Therefore, the following connection structure can be adopted. The following connection includes: a connecting plate 26, a first Velcro, a mounting frame 22, a positioning rod 23 and a connecting belt 24. The connecting plate 26 is detachably fixed to the outer side of the right protective module 2 by the first Velcro, and a mounting frame 22 is embedded on the connecting plate 26. The mounting frame 22 is spaced apart. A plurality of positioning rods 23 are provided, and the two ends of the positioning rods 23 are movably connected to the two sides of the mounting frame 22 respectively. There are a plurality of connecting belts 24, which are sewn on the ends of the inflatable cushion respectively. When in use, the connecting belt 24 is wound around each positioning rod 23 in a serpentine shape and then tightened. The connecting belt 24 is clamped and fixed by the pressure of the positioning rod 23, and finally the end of the connecting belt 24 is fixed to the inflatable cushion by the second Velcro 25. This effectively reduces the area of the Velcro, and can also ensure the connection strength, which is more convenient for disassembly.

In this embodiment, installation grooves are provided on both left and right sides of the inner wall of the installation frame 22 , and bearings capable of connecting to the positioning rod 23 are provided in the installation grooves.

In this embodiment, the first Velcro and the second Velcro 26 both include a hook surface and a fleece surface, and the connecting plate 26, the right protective module 2, the connecting belt 24 and the inflatable cushion are respectively provided with a hook surface and a fleece surface.
