Description

Technical Field

[0001] The invention belongs to the technical field of operating tables, and in particular relates to a combined operating table capable of seeing through X-rays during an operation. Background Art

[0002] Orthopedic surgery, especially internal fixation surgery for limb fractures, relies heavily on intraoperative fluoroscopy, which is of great reference value for the fracture reduction effect and the accuracy of the internal fixation position. With the help of fluoroscopy results, it is possible to timely discover unsatisfactory fracture reduction and poor internal fixation position, and timely correct and solve them during surgery to eliminate medical risks. Whether the operating table can facilitate the operation will directly affect the progress and effect of the operation. Intraoperative C-arm X-ray fluoroscopy is often required in orthopedic surgery to determine anatomical landmarks or fracture reduction. Existing orthopedic operating tables include ordinary operating tables and orthopedic traction tables. The characteristics of this type of operating table are that the bed surface is mostly made of metal structure, the back is uneven, and the bed support is located in the middle, mostly in a large cylindrical shape. Therefore, this type of operating table can only take lateral X-rays during orthopedic surgery. Frontal X-rays are often blocked by the cylindrical pillars or affected by various metal parts of the bed. The impact is most serious when orthopedic surgeries in the middle part of the human body, such as pelvic fractures and hip fractures, require fluoroscopy. Therefore, when frontal X-rays are required, the anesthetized patient often needs to be moved to minimize metal obstruction, which brings inconvenience to the surgical operation process.

[0003] Some other operating tables only have the bed panel made of X-ray-permeable carbon fiber plate or other materials, and the bed panel is supported by a metal frame around it. When projecting the C-arm anteroposterior film, since the position of the limbs does not need to be changed too much, it can basically meet the development needs. However, when projecting lateral oblique X-rays, since the bed frame and bracket are made of metal materials, the rays will be blocked and cannot be transmitted through the X-rays. Even if the bed panel can transmit X-rays, it will overlap with the contralateral limbs or trunk and cannot be accurately developed. In addition, due to the anesthesia effect, the patient's limbs cannot be coordinated to place in the correct perspective position. It is often necessary for the surgeon to lift the patient, avoid and interleave with the contralateral limbs or trunk before exposure and development, so that a reliable image can be fully projected. Lifting the patient's body by hand will still cause micro-movement during exposure and development, which will also cause artifacts in the image and unclear development, making it difficult to accurately judge the fracture reduction effect during surgery, prolonging the operation time, increasing the chance of intraoperative contamination and postoperative infection rate, which is not good for the health of doctors and the safety of patients' surgery, and causing medical risks.

[0004] Existing pure fiber orthopedic operating tables are mostly made by foreign professional companies and are monopolized products. Their manufacturing process is complex, they are all modular, inconvenient to use, easy to damage, and especially expensive, costing millions to tens of millions, and are generally unavailable to small and medium-sized hospitals below the county level. Given the very low per capita medical level in my country, developing an operating table with a simple structure, low cost, and barrier-free perspective can significantly reduce treatment costs and benefit more patients.

DETAILED DESCRIPTION

[0029] The present invention aims to improve an operating table capable of seeing through X-rays, Figure 1-Figure 14 Various embodiments shown, as well as other embodiments not included in the figures, are described in detail below.

[0030] Example 1: Basic version of the combined operating table Figure 1 and Figure 2 As shown, about 3-5 bed units are connected in sequence to form a connected structure for use as an operating bed. Figure 1 and Figure 2 Only the most streamlined mode of the operating bed is shown, and further additional components can be added to the combination, such as adding slides or kits on its side for installing surgical instruments. The model of each bed unit that constitutes the combined bed is as consistent as possible to facilitate random assembly. However, they can also be inconsistent. For example, the bed units near the head of the bed or the bed are set separately, while the model of the bed unit in the middle remains consistent. Regardless of whether the bed unit model changes, the connecting parts are basically the same, so as to simplify the installation procedure and achieve fast and unified assembly. In this embodiment, a combined operating bed is formed by connecting and combining multiple bed units. The operating bed can be optimally assembled and modified according to the patient's body shape to accommodate adults and children, as well as patients of different heights, fatness, and thinness.

[0031] Each bed unit includes a horizontally arranged U-shaped upper frame 1 and a plurality of supporting legs 2. The U-shaped upper frame 1 includes two side bars and a bottom bar, which are located at the four top corners of the U-shaped upper frame 1 and are connected downward to the corresponding supporting legs 2. The U-shaped upper frame 1 or the supporting legs 2 of the bed unit can be made of square tubes such as Figure 1 , or use a round tube such as Fig.10 , and a combination of square tubes and round tubes.

[0032] like Figure 2As shown, the ends of the two side rods of the open end of the U-shaped upper frame 1 are respectively provided with supports 4, and the two ends of the carbon fiber rod 3 are respectively sleeved in the two side supports 4. In this embodiment, the carbon fiber rod 3 only provides support. At the same time, a plurality of parallel traction belts 5 are sleeved and connected between the two side rods of the U-shaped upper frame 1. The two side rods and the bottom rod of the U-shaped upper frame 1 are metal rods with sufficient strength, while there is no metal rod connection at the open end of the U-shaped upper frame 1, which is a weak force-bearing part, but through the support of the carbon fiber rod 3 and the tightening of the traction belt 5, a high-strength stable structure can still be formed. In this embodiment, the carbon fiber rod 3 is used as a support, and the two side rods of the U-shaped upper frame 1 are pulled by the traction belt 5, so that the U-shaped upper frame 1 is in a firm state as the support surface of the operating bed. Among them, the carbon fiber rods 3 of the multiple bed monomers constituting the operating bed are located on the left or right side of the bed body, that is, close to the side of the C-arm X-ray machine 36. During orthopedic surgery, a C-arm X-ray machine 36 is required for perspective. The carbon fiber rod 3 at the open end of the U-shaped upper frame 1 will not cause interference during projection, which is conducive to the smooth progress of the surgery and avoids repeated pushing of the surgical patient during the surgery, affecting the surgery and increasing the risk of infection.

[0033] The multiple bed units constituting the operating bed are connected as a whole by connecting members. In this embodiment, the connecting members are provided with transverse through holes on the supporting legs 2 of the adjacent bed units, and connecting bolts 7 are installed through them. Figure 1 or Figure 4 The connection structure shown is this connection method.
