Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary technology, and in particular to a prone positioning support for surgery under CT scan. Background Technology

[0002] The incidence of malignant tumors is increasing year by year, and most patients with malignant tumors have already lost the opportunity for surgery by the time they are diagnosed. With the development of imaging technologies such as ultrasound, CT, and MRI, the application of minimally invasive techniques, including cryoablation, radiofrequency ablation, microwave ablation, radioactive particle ablation, laser ablation, ultrasound ablation, and chemical ablation, for the ablation treatment of solid tumors that cannot or are not suitable for surgical resection has become an important part of modern cancer treatment. Minimally invasive ablation treatment for solid tumors generally needs to be performed under the guidance of imaging equipment (including B-ultrasound, CT, and MRI). As the types of minimally invasive ablation treatments gradually increase and become more widespread in medical institutions, some corresponding problems in minimally invasive treatment procedures are also gradually emerging.

[0003] Currently used ablation devices such as microwave, radiofrequency, cryotherapy, and irreversible electroporation for tumor ablation therapy follow similar surgical procedures. All involve percutaneous puncture of the ablation needle through a connecting tube after image-guided positioning, allowing the needle to reach the ablation device. During our procedures in the CT room, due to the long treatment time and prolonged prone position, pressure ulcer protection of the limbs is necessary. Furthermore, some procedures require anesthesia or analgesia, which presents challenges in the prone position. Patients must lie prone on the CT bed for various minimally invasive surgeries guided by the CT equipment. During these procedures, patients need a comfortable position to tolerate the long surgery. On the other hand, maintaining unobstructed breathing is crucial when relying solely on intravenous anesthesia or analgesia. The prone position restricts breathing space, and the concave surface of the CT bed further hinders breathing in this position. Currently, when patients undergo prone surgery on a CT scanner, the existing positioning pads are of a fixed size, which limits the applicable population and results in poor compatibility and comfort. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a prone positioning support for surgery under CT scan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prone positioning support for surgery under a CT scanner includes a base, a sliding assembly disposed on the base, and two positioning pads fixedly connected to the sliding assembly. The side of the base that contacts the machine tool is configured with a protruding arc-shaped surface structure. The sliding assembly includes two slide rods. The two slide rods are spaced apart on the other side of the base, and the length direction of the positioning pads is perpendicular to the length direction of the slide rods. The two positioning pads are spaced apart, with one end of each positioning pad slidably connected to one of the slide rods and the other end of each positioning pad slidably connected to the other slide rod.

[0007] By adopting the above technical solution, the side of the base that contacts the machine tool is designed with a protruding arc-shaped surface structure, which makes the base fit the machine tool better and the installation more stable. This helps to ensure the stability of the patient's position during the operation. The two positioning pads can be slidably set on the base through the slide bar, which makes it easy to adjust the distance between the two positioning pads according to people of different body types. This makes the system more compatible, easier to adjust, and more comfortable to use.

[0008] Furthermore, an installation chamber is provided on the other side of the base, and the two sliding rods are fixed in the installation chamber for protection. The sliding assembly also includes two sliders, with each positioning pad fixedly connected to one slider. One end of the slider is slidably mounted on one of the sliding rods, and the other end of the slider is slidably mounted on the other sliding rod, reducing the contact area, improving adjustment efficiency, and making operation more convenient.

[0009] Furthermore, the sliding assembly also includes an adjusting rod. One end of the adjusting rod has a knob, and the rod body has external threads. Both sliders have internally threaded mounting holes. The knob of the adjusting rod is located on the outside of the base, and the other end of the adjusting rod passes through the base and is threaded into the two mounting holes. The adjusting rod is threaded to the two sliders. By rotating the knob clockwise or counterclockwise, the two sliders can be moved closer or further apart to adjust the distance between the two positioning pads. The two positioning pads adjust synchronously, improving adjustment efficiency and comfort, and can accommodate people of different body types, offering greater compatibility.

[0010] Furthermore, the adjusting lever is positioned between the two sliding rods, which facilitates the synchronous movement of both ends of the slider, making adjustment more convenient.

[0011] Furthermore, the base includes an arc-shaped fixing plate and a sealing plate. The longitudinal section of the fixing plate is set as an arc-shaped structure, and the side of the fixing plate opposite to the arc-shaped surface is fixedly connected to the sealing plate. The sealing plate is provided with the mounting chamber, and the side of the sealing plate opposite to the fixing plate is provided with two through grooves. Each set of sliders and the positioning pad are provided with one of the grooves to improve sealing, extend service life, and prevent interference during operation. Each slider is provided with several support rods, and the end of the support rod away from the slider passes through the groove and connects to the positioning pad.

[0012] Furthermore, the width of the groove is smaller than the width of the slider, which improves the sealing performance, helps protect the internal sliding structure, and extends the service life.

[0013] Furthermore, the side of the positioning pad facing the slide bar is designed as a planar structure, which can increase the force-bearing area and improve the load-bearing strength. The other side of the positioning pad is designed as an arc-shaped surface structure with gradually changing curvature along the direction of the human body, which can improve comfort.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This invention features a protruding arc-shaped surface structure on the side of the base that contacts the machine tool, allowing the base to fit more closely to the machine tool and ensuring a more stable installation. This helps to guarantee the stability of the patient's position during surgery. The two positioning pads can be slidably mounted on the base via a slide bar, making it easy to adjust the spacing between the two positioning pads according to different body types. This design offers greater compatibility, convenient adjustment, and greater comfort. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The embodiments of this utility model will be described in further detail below.

[0026] A prone positioning support 1 for surgery under CT scan, such as Figure 1 , Figure 2 , Figure 3As shown, it includes a base 2, a sliding assembly mounted on the base 2, and two positioning pads 4 fixedly connected to the sliding assembly. The side of the base 2 that contacts the machine tool is designed with a protruding arc-shaped surface. The sliding assembly includes two slide rods 31. The two slide rods 31 are spaced apart on the other side of the base 2, and the length direction of the positioning pads 4 is perpendicular to the length direction of the slide rods 31. The two positioning pads 4 are spaced apart, with one end of each positioning pad 4 slidably connected to one of the slide rods 31, and the other end of each positioning pad 4 slidably connected to the other slide rod 31.

[0027] The side of the base 2 that contacts the machine tool is designed with a protruding arc-shaped structure, which allows the base 2 to fit more closely to the machine tool, making the installation more stable and helping to ensure the stability of the patient's position during surgery. The two positioning pads 4 can be slidably set on the base 2 via the slide bar 31, making it easy to adjust the spacing between the two positioning pads 4 according to people of different body types, resulting in higher compatibility, convenient adjustment, and more comfortable use. Of course, multiple positioning pads 4 can also be densely arranged to increase the force-bearing area for the patient when prone, making prone positioning more comfortable.

[0028] In some embodiments, please refer to Figure 3 The other side of the base 2 is provided with an installation chamber 23, and two sliding rods 31 are fixed in the installation chamber 23 for protection. The sliding assembly also includes two sliders 32, and each positioning pad 4 is fixedly connected to one slider 32. One end of the slider 32 is slidably mounted on one of the sliding rods 31, and the other end of the slider 32 is slidably mounted on the other sliding rod 31, reducing the contact area, improving the efficiency of adjustment, and making operation more convenient.

[0029] In some embodiments, please refer to Figure 3 To improve adjustment efficiency and convenience, the sliding assembly also includes an adjustment lever 33. One end of the adjustment lever 33 has a knob 331, and the lever body has an external thread 332. Both sliders 32 have internally threaded mounting holes. The knob 331 of the adjustment lever 33 is located on the outside of the base 2, and the other end of the adjustment lever 33 passes through the base 2 and is threaded into the two mounting holes, thus securing it to the base 2. The adjustment lever 33 is threaded to the two sliders 32. Rotating the knob 331 forwards or backwards moves the two sliders 32 closer together or further apart, adjusting the distance between the two positioning pads 4. The two positioning pads 4 adjust synchronously, improving adjustment efficiency and comfort, and making it suitable for people of different body types, thus offering greater compatibility.

[0030] Specifically, the adjusting lever 33 is positioned between the two sliding rods 31, which facilitates the synchronous movement of both ends of the slider 32, making adjustment more convenient.

[0031] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 4 The base 2 includes an arc-shaped fixing plate 21 and an encapsulation plate 22. The longitudinal section of the fixing plate 21 is set as an arc-shaped structure, and the side of the fixing plate 21 facing away from the arc-shaped surface is fixedly connected to the encapsulation plate 22. An installation chamber 23 is provided inside the encapsulation plate 22, and two through grooves 24 are provided on the side of the encapsulation plate 22 facing away from the fixing plate 21. Each set of sliders 32 is provided with a groove 24 between it and the positioning pad 4 to improve sealing, extend service life, and prevent interference during operation. Each slider 32 is provided with several support rods 34, and the end of the support rod 34 away from the slider 32 passes through the groove 24 and connects to the positioning pad 4.

[0032] The width of the groove 24 is smaller than the width of the slider 32, which improves the sealing performance, helps protect the internal sliding structure, and extends the service life.

[0033] The side of the positioning pad 4 facing the slide bar 31 is designed as a flat structure, which can increase the area of ​​force bearing and improve the load-bearing strength. The other side of the positioning pad 4 is designed as an arc-shaped surface structure with gradually changing curvature along the direction of the human body, which can improve comfort.

[0034] In use, place the entire prone positioning bracket on the machine tool and adjust the position of the base 2 to better fit the recessed area of ​​the machine tool. Depending on the patient's physique, rotate knob 331. Adjusting lever 33, via external thread 332, drives two sliders 32 to move in opposite directions, causing the two positioning pads 4 on them to move further apart or closer together until they adapt to the patient's physique. Adjusting lever 33 has a self-locking function; it automatically locks after adjustment to prevent the two positioning pads 4 from moving during use, avoiding safety hazards. The patient lies prone on the positioning pads 4, improving patient comfort and positional stability during surgery, maintaining unobstructed breathing, and effectively stabilizing the patient's limbs, thus allowing the surgery to be completed smoothly.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
