Abstract
Claims
1. A CT intervention with a cross-shaped frame, characterized in that: The frame includes a skeleton consisting of two horizontal bars and two vertical bars. The distance between the two horizontal bars is the same as the distance between the two vertical bars. The length and cross-section of the two horizontal bars and the two vertical bars are the same. The center position of the two horizontal bars and the two vertical bars is a central grid. A central ring is provided in the central grid of the grid frame. The central ring is connected to the frame of the grid frame by four support rods arranged in a ring array.
2. The cross-shaped frame for CT intervention according to claim 1, wherein: One of the horizontal bars and one of the adjacent vertical bars are provided with equally spaced scale bars, which extend away from the central ring and perpendicular to the grid frame. The scale bars are used to indicate the scale during CT imaging.
3. The CT interventional use cross-shaped stand according to claim 2, characterized in that: The scale rod includes several first scale rods of the same length and a second scale rod that is longer than the first scale rods.
4. The cross-shaped frame for CT intervention according to claim 3, wherein: Both the horizontal and vertical bars have rounded corners in their cross-sections.
5. The CT interventional use cross-shaped stand according to claim 4, wherein: The grid frame, the first scale rod, the second scale rod, and the central ring are all made of stainless steel.
6. The CT interventional use cross-shaped stand according to claim 5, wherein: All support rods are made of PVC.
7. A CT interventional treatment kit comprising a CT interventional frame as described in any one of claims 1-6, comprising a first tray and a second tray stacked on top of each other, and an outer packaging wrapped around the outside of the first tray and the second tray, wherein a sterile drape is laid flat on the first tray, characterized in that: The first tray and the second tray are respectively provided with a first slot and a second slot for placing medical devices. The cells in the second slot are divided into a syringe storage area, a miscellaneous storage area and a positioning device storage area arranged sequentially along the length of the second tray. The positioning device includes an angle ruler, a right angle ruler and the grid frame.
8. The CT intervention treatment package of the CT intervention well-shaped frame according to claim 7, characterized in that: The positioning device storage area includes angle ruler cells, right angle ruler cells, and grid cells arranged sequentially along the width of the second tray.
