Description

Technical Field

[0001] The utility model relates to the technical field of children's operating frames, in particular to a medical children's interventional operating frame. Background Art

[0002] Interventional therapy is a minimally invasive treatment performed using modern high-tech means. Under the guidance of medical imaging equipment, special catheters, guidewires and other precision instruments are introduced into the human body to diagnose and locally treat pathologies in the body. Interventional surgery has the characteristics of small incisions, less pain and quick recovery, and has been widely used in clinical practice. Interventional surgical instruments are relatively sophisticated and difficult to operate, especially for children. Children's bodies are not fully developed, they are smaller in size and have thinner blood vessels, and the difficulty of the operation increases exponentially. The operation often requires intervention through the limbs. During the operation, medical staff are often required to hold the child's body to facilitate the doctor's operation. The medical staff's hand support is not only inconvenient to operate, but may also cause shaking, which can easily lead to operational errors.

[0003] The Chinese utility model patent with announcement number CN208910511U in the prior art discloses a medical pediatric interventional surgical frame, including a connecting frame, a mounting plate and a rotating rod, a fixing rod is welded on the upper side of the connecting frame, and the upper end of the fixing rod is welded with a connecting seat, a connecting rod is welded on the upper part of the connecting seat, and the outer side of the connecting rod is rotatably connected to the support frame, the upper part of the connecting seat is threadedly connected to a positioning bolt, and a friction block is glued to one end of the positioning bolt close to the support frame, and the upper side of the support frame is connected to the mounting plate by screws, and the upper side of the mounting plate is rotatably connected to the rotating rod, and the other end of the rotating rod is rotatably connected to the connecting rod, and the other end of the connecting rod is rotatably connected to the connecting plate. The surgical frame can fix the part of the child that requires surgery during the operation to avoid shaking during the operation. The surgical frame can adjust the clamping degree according to the child's body shape, and can also be rotated to facilitate adjustment to the angle most suitable for the doctor's operation. It is commonly used for upper and lower limbs.

[0004] However, when the above device fixes the upper or lower limbs of a child, the clamping is performed through the clamping block and the rotating rod. Not only is the clamping effect unstable, but the clamping comfort is poor, which can easily cause discomfort to the child. Utility Model Content

[0005] The purpose of the utility model is to provide a medical interventional surgery stand for children to solve the technical problems in the above-mentioned prior art.

[0006] The utility model provides a medical interventional surgery frame for children, comprising a connecting frame, a rotating frame, a mounting plate and an arcuate plate. The rotating frame is L-shaped, and one end of the rotating frame is rotatably mounted on the connecting frame, the mounting plate is fixed to the other end of the rotating frame, the arcuate plate is fixed to a side of the mounting plate away from the rotating frame, and further comprises a clamping airbag, which is fixed to a side of the arcuate plate facing the mounting plate. The clamping airbag can be expanded, and when the clamping airbag is expanded, it can clamp and fix the upper limbs or lower limbs of a child.

[0007] Furthermore, three balloons are installed in the clamping airbag, and the three balloons are connected to each other through a connecting tube. One of the balloons is equipped with an air injection tube, which extends outward from one end of the balloon and passes through the clamping airbag and the arc plate and is connected to the air pump.

[0008] Furthermore, among the three balloons, the elastic coefficient of the balloon located at the highest point of the arc-shaped plate is smaller than the elastic coefficients of the other two balloons.

[0009] Furthermore, a filling layer is formed between the clamping airbag and the spherical balloon, and the filling layer is filled with a non-Newtonian fluid.

[0010] Furthermore, reinforcing ribs are installed on the rotating frame.

[0011] Furthermore, a fixing column is installed on the connecting frame through a thread, and when the fixing column contacts the rotating frame, it can interfere with and limit the rotation of the rotating frame through friction.

[0012] Furthermore, a friction block is installed on the side of the fixed column facing the rotating frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The utility model fixes the upper or lower limbs of a child by expanding the clamping airbag, which not only has a better fixation effect but also disperses the clamping force, thereby improving the comfort during clamping;

[0015] (2) The utility model uses an air pump to input air to drive the three balloons to expand, and the elastic coefficient of the balloon 210 at the highest point is the smallest, so its expansion degree is the smallest, and the elastic coefficient of the balloons on both sides is larger, so the expansion degree of the balloons on both sides is larger than the expansion degree of the balloon at the highest point. Through this setting, it can better fit the upper or lower limbs of the child, further strengthening the clamping and fixing effect;

[0016] (3) The present invention is filled with non-Newtonian fluid, so that the clamping effect is softer during the clamping operation. In addition, if an unexpected situation occurs and an external force acts on the clamping airbag, the instantaneous external force will come into contact with the non-Newtonian fluid, causing the non-Newtonian fluid to harden and protect the clamped part of the child.

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] The following combination Figures 1 to 3 As shown, an embodiment of the present invention provides a medical interventional surgical frame for children, including a connecting frame 100, a rotating frame 110, a mounting plate 120 and a curved plate 130. The rotating frame 110 is L-shaped, and one end of the rotating frame 110 is rotatably mounted on the connecting frame 100, the mounting plate 120 is fixed to the other end of the rotating frame 110, and the curved plate 130 is fixed to the side of the mounting plate 120 away from the rotating frame 110. It also includes a clamping airbag 200, which is fixed to the side of the curved plate 130 facing the mounting plate 120. The clamping airbag 200 can be inflated, and when the clamping airbag 200 is inflated, it can clamp and fix the upper or lower limbs of the child.

[0029] By expanding the clamping airbag 200 to fix the child's upper or lower limbs, not only the fixation effect is better, but also the clamping force is more dispersed, thereby improving the comfort during clamping.

[0030] Preferably, three balloons 210 are also installed in the clamping airbag 200, and the three balloons 210 are connected to each other through a connecting tube 220. One of the balloons 210 is installed with an air injection tube 230, which extends outward from one end of the balloon 210 and passes through the clamping airbag 200 and the arc plate 130 and is connected to the air pump (not shown in the figure).

[0031] Preferably, among the three balloons 210 , the elastic coefficient of the balloon 210 located at the highest point of the arc-shaped plate 130 is smaller than the elastic coefficients of the other two balloons 210 ;

[0032] Air is input through an air pump to drive the three balloons 210 to expand, and the elastic coefficient of the balloon 210 at the highest point is the smallest, so its expansion degree is the smallest. The elastic coefficient of the balloons 210 on both sides is larger, so the expansion degree of the balloons 210 on both sides is larger than the expansion degree of the balloon 210 at the highest point. Through this setting, it can better fit the upper or lower limbs of the child, further enhancing the clamping and fixing effect.

[0033] Preferably, a filling layer 240 is formed between the clamping airbag 200 and the balloon 210, and the filling layer 240 is filled with a non-Newtonian fluid. Through the filling of the non-Newtonian fluid, the clamping effect is softer during the clamping operation, and if an accident occurs, an external force acts on the clamping airbag 200. When the instantaneous external force comes into contact with the non-Newtonian fluid, the non-Newtonian fluid hardens and can also protect the clamped part of the child.

[0034] Preferably, reinforcing ribs 140 are installed on the rotating frame 110 .

[0035] Preferably, a fixing column 150 is installed on the connecting frame 100 through a thread. When the fixing column 150 contacts the rotating frame 110, it can interfere with and limit the rotation of the rotating frame 110 through friction.

[0036] Preferably, a friction block 160 is installed on the side of the fixing column 150 facing the rotating frame 110 .

[0037] During use, the medical staff first fixes the connecting frame 100 to the corresponding position on the side of the operating table, then rotates the rotating frame 110 to a suitable angle, tightens the fixing column 150, so that the friction block 160 contacts the rotating frame 110, and then the medical staff inserts the child's upper or lower limbs into the space between the curved plate 130 and the mounting plate 120, and then starts the air pump to inflate the balloon 210. The expansion of the balloon 210 drives the clamping airbag 200 to expand together, and as the clamping airbag 200 expands, the child's upper or lower limbs are gradually tightened and clamped.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
