Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of medical products, more particularly, relates to a non-slip pad for hip joint surgery. BACKGROUND
[0002] Hip arthroplasty, hip arthroscopy surgery and the like require continuous strong traction on the affected limb during the operation. In order to avoid the patient from sliding along the operating table to the tail or both sides of the bed, the fixing methods commonly used in the prior art include fixing belt fixing method and perineal column counter traction method. Among them, the fixing belt fixing method refers to tightly binding the patient's thorax or pelvis on the operating table by using a wide cloth belt or a special binding belt. This method has limited fixing force, and sliding may still occur under a large traction force. At the same time, the over-tight binding can limit the thoracic breathing movement, and may cause pressure marks, friction injuries or nerve compression on the patient's skin. The perineal column counter traction method refers to placing a column wrapped with a soft pad on the patient's perineum, and resisting the traction force by the column against the pubic bone or the thigh root, which is the most commonly used method at present, but there is a risk of perineal soft tissue crush injury, nerve injury and skin pressure sores. SUMMARY
[0003] 1. PROBLEMS TO BE SOLVED Based on this, the purpose of the present application is to provide a non-slip pad for hip joint surgery, which is laid between the patient and the operating table during the operation, and reduces the displacement caused by the traction force and the harm caused to the patient by the fixing method by increasing the movement resistance between the patient and the non-slip pad, and between the non-slip pad and the operating table.
[0004] 2. TECHNICAL SOLUTION In order to solve the above problems, the technical scheme adopted by the present application is as follows: The present application provides a non-slip pad for hip joint surgery, comprising a skin-friendly layer and a non-slip layer, a flow layer is arranged between the skin-friendly layer and the non-slip layer, the flow layer comprises a closed bag filled with flow particles, a through hole is arranged on the skin-friendly layer, an elastic assembly is arranged in the through hole, the elastic assembly comprises a protrusion and a spring, one end of the spring is connected to the protrusion, and the other end of the spring is connected to the top surface of the flow layer, and the spring assembly can move up and down to make the protrusion higher or lower than the top surface of the skin-friendly layer.
[0005] Preferably, the material of the non-slip layer is silicone or rubber.
[0006] Preferably, the lower surface of the non-slip layer is provided with a non-slip texture, and the non-slip texture comprises micro-protrusions, grooves and suction cups.
[0007] Preferably, the elastic assemblies are arranged in an array.
[0008] Preferably, the protrusions are made of flexible material.
[0009] Further preferably, the flexible material comprises silicone, polyurethane and rubber.
[0010] Preferably, the protrusions are cylindrical or hemispherical in shape.
[0011] Under the action of the patient's body weight, the protrusions of the elastic assembly in contact with the patient move downward and closely adhere to the patient's body, while the remaining protrusions remain above the top surface of the skin-friendly layer, forming a concave-convex structure on the top surface of the anti-skid pad. Due to the elastic effect of the springs, this concave-convex structure dynamically adjusts with changes in the patient's body position, thereby limiting the displacement of the patient.
[0012] Preferably, the material of the flow particles is polypropylene foam or polystyrene foam.
[0013] Under the action of the patient's body weight, the flow layer deforms, the patient's body, especially the shoulders and hips, sinks on the anti-skid pad, the contact area between the two increases, the friction force is greater, and the comfort of the patient is also increased.
[0014] Preferably, the material of the skin-friendly layer is medical-grade memory sponge or silicone gel.
[0015] Preferably, the area of the anti-skid layer is larger than the area of the skin-friendly layer.
[0016] It should be noted that when the area of the anti-skid layer is larger than the area of the skin-friendly layer, the edge rolling phenomenon that occurs during the displacement of the anti-skid pad can be avoided.
[0017] 3. Advantages Compared with the prior art, the advantages of the present application are: (1) The anti-skid pad for hip joint surgery of the present application, under the action of the patient's body weight, the elastic assembly in contact with the patient moves downward, the protrusions closely adhere to the patient's body, while the protrusions of the elastic assembly that have not moved downward remain above the top surface of the skin-friendly layer, forming a concave-convex structure on the top surface of the anti-skid pad that dynamically adjusts with changes in the patient's body position. At the same time, the flow layer also deforms under the action of the patient's body weight, especially the shoulders and hips sink, causing the anti-skid pad to form a shape that is adapted to the human body, increasing the contact area between the patient and the anti-skid pad, and thereby increasing the friction force between the two. Therefore, under the combined action of the elastic assembly and the flow layer, with the help of the patient's body weight, the displacement resistance between the anti-skid pad and the patient is increased.
[0018] (2) The anti-skid pad for hip joint surgery of the present application not only increases the displacement resistance between the patient and the anti-skid pad, but also increases the friction force between the anti-skid pad and the operating bed by providing anti-skid textures on the lower surface of the anti-skid layer, the combination of the two greatly reduces the displacement of the patient caused by traction, thereby reducing the harm to the patient caused by the fixation method.

[0021] It should be noted that when a component is referred to as being "mounted" on another component, it can be directly on the other component or the two components can be integrated as one unit; when a component is referred to as being "connected" to another component, it can be directly connected to the other component or the two components can be integrated as one unit. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
[0022] The present invention will be further described below with reference to specific embodiments.
[0023] Example 1 like Figure 1 As shown, an anti-slip pad for hip joint surgery includes a skin-friendly layer 1, an anti-slip layer 2, a flow layer 3, a through-hole 4, and an elastic component 5, wherein the elastic component 5 includes a protrusion 51 and a spring 52. The flow layer 3 is located between the skin-friendly layer 1 and the anti-slip layer 2, and the flow layer 3 includes a closed bag filled with flowable particles. The skin-friendly layer 1 has a through-hole 4, and the elastic component 5 is disposed within the through-hole 4. One end of the spring 52 is connected to the protrusion 51, and the other end is connected to the top surface of the flow layer 3. The elastic component 5 can move up and down to make the protrusion 51 higher or lower than the top surface of the skin-friendly layer 1.
[0024] Under the action of the patient's body gravity, the elastic component 5 in contact with the patient moves downward, the part of the protrusions 51 closely contacts the patient's body, while the rest of the protrusions 51 remains above the top surface of the skin-friendly layer 1, so that the top surface of the anti-skid pad forms a concave-convex structure, further limiting the displacement of the patient. Since the flow layer 3 is filled with flow particles (polypropylene foam material or polystyrene foam material), the anti-skid pad sinks under the action of the patient's body gravity, especially the shoulder and hip, forms a shape suitable for the human body, increases the contact area between the two, and increases the friction, and also increases the comfort of the patient.
[0025] The material of the anti-skid layer 2 can be silicone or rubber, and the lower surface is provided with anti-skid textures, such as micro-protrusions 21 (see Figure 2 ), grooves 22 (see Figure 3 ) and suction cups 23 (see Figure 4 ). Due to the presence of the anti-skid layer 2, there is a large friction between the anti-skid pad and the operating bed.
[0026] In order to increase the comfort of the patient, the protrusions 51 are made of flexible materials, such as silicone, polyurethane or rubber, and the material of the skin-friendly layer 1 is medical-grade memory sponge, silicone gel or low-allergy soft foam material.
[0027] In order to avoid the edge of the anti-skid pad for hip joint surgery from rolling during movement, the area of the anti-skid layer 2 is larger than that of the skin-friendly layer 1.
[0028] The above is a schematic description of the present application and its embodiments, which is not restrictive, and the embodiments shown in the examples are only one of the embodiments of the present application, and the actual embodiments are not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the spirit of the present application, without creative design, similar embodiments and examples of the technical solution are not creative design, which should belong to the protection scope of the present application.
