[0039] The utility model discloses a gastrointestinal machine CBCT detection bracket, which is installed on the gastrointestinal machine so that the gastrointestinal machine has a CBCT function, greatly improves the use value of the gastrointestinal machine, and improves the diagnosis effect on patients.

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] See also Figures 2 to 5 The gastrointestinal machine CBCT detection bracket of the utility model comprises a rotating frame 2 and a head fixing frame 1. The top of the rotating frame 2 is rotatably connected to the head fixing frame 1, and the bottom of the rotating frame 2 is connected to the rotating foot pedal 4 of the gastrointestinal machine 5. The head fixing frame 1 is connected to the bed surface 3 of the gastrointestinal machine 5. The top and bottom of the rotating frame 2 are defined relative to the orientation of the patient when in use. The end of the rotating frame 2 close to the patient's head is the top, and the end close to the patient's feet is the bottom.

[0042] The rotating foot pedal 4 and the bed surface 3 of the gastrointestinal machine 5 are both existing structures on the gastrointestinal machine 5 , and the CBCT detection bracket of the gastrointestinal machine is installed on the existing gastrointestinal machine 5 .

[0043] The gastrointestinal machine CBCT detection bracket of the utility model is installed on the rotating foot pedal 4 and the bed surface 3 of the gastrointestinal machine 5. During the detection, the patient to be detected stands on the rotating frame 2, and the patient rotates stably with the rotating foot pedal 4, thereby realizing the CBCT function of the gastrointestinal machine, which can greatly improve the value of the gastrointestinal machine and enhance the diagnostic effect on the patient.

[0044] Specifically, the head fixing frame 1 includes a supporting main board 101 and a supporting arm 104. Figures 6 to 8 The support arm 104 is connected to the support main board 101, and the connection here can be welding. The top of the rotating frame 2 is rotatably set in the limiting groove 1041 of the support arm 104. The supporting main board 101 is connected to the bed surface 3. It can be seen that one end of the rotating frame 2 is limited by the limiting groove 1041, and the other end is limited by the rotating foot pedal 4. Since the rotating frame 2 is rotatably set in the limiting groove 1041, when the rotating foot pedal 4 of the gastrointestinal machine 5 rotates, the rotating frame 2 is driven to rotate.

[0045] In order to facilitate the connection of the head fixing frame 1 to the bed surface 3, the head fixing frame 1 further includes a connecting seat 102, one end of the connecting seat 102 is connected to the supporting main board 101, and the other end is connected to the bed surface 3. In other words, the head fixing frame 1 is connected to the bed surface 3 through the connecting seat 102.

[0046] In a specific embodiment, the connection seat 102 is an L-shaped seat body. Figure 6 , the bent end of the connecting seat 102 is slidably arranged in the slide groove 301 on the side edge of the bed surface 3, that is, the bent end of the connecting seat 102 is slidably connected to the slide groove 301, and the slide groove 301 is extended along the length direction of the bed surface 3, so that the connecting seats 102 of different heights can be adapted. By setting the slide groove 301, the displacement of the connecting seat 102 in the direction perpendicular to the bed surface 3 is better avoided. In order to position the connecting seat 102, a locking knob 103 is threadedly connected on the side wall of the connecting seat 102 opposite to the bent end, and the locking knob 103 is threadedly connected to the connecting seat 102. The tail end of the locking knob 103 is pressed against the edge of the bed surface 3 to prevent the locking knob 103 from sliding along the slide groove 301. In order to facilitate manual tightening, the locking knob 103 is a plum blossom knob.

[0047] In order to ensure the reliability of the connection between the head fixing frame 1 and the bed surface 3, two connecting seats 102 are provided, and the two connecting seats 102 are respectively fixedly connected to the two ends of the supporting main board 101. The connection method of the connecting seat 102 and the supporting main board 101 can be a connecting piece connection or welding, or other commonly used connection methods in the art, which will not be repeated here.

[0048] In order to achieve reliable limiting of the rotating frame 2 , two support arms 104 are provided. A limiting groove 1041 is respectively provided on the opposite sides of the two support arms 104 . The top of the rotating frame 2 is rotatably disposed in the two opposite limiting grooves 1041 .

[0049] Further, the rotating frame 2 includes a connecting bottom plate 201, a connecting side plate 202 and a connecting top frame 203. The connecting bottom plate 201 is connected to the rotating foot pedal 4 of the gastrointestinal machine 5. One end of the connecting side plate 202 is fixedly connected to the connecting bottom plate 201, and the other end is fixedly connected to the connecting top frame 203. The connecting top frame 203 is rotatably connected to the head fixing frame 1. Among them, the connecting bottom plate 201 is connected to the rotating foot pedal 4 of the gastrointestinal machine 5 through a connecting piece, the connecting side plate 202 is connected to the connecting bottom plate 201 through a connecting piece, and the connecting side plate 202 is connected to the connecting top frame 203 through a connecting piece. The connecting piece here is a connecting screw or a connecting bolt, and it can also be other connecting methods commonly used by those skilled in the art, which are not limited here. Specifically, the connecting top frame 203 is rotatably set in the limiting groove 1041.

[0050] In order to ensure the smooth rotation of the rotating frame 2, the connecting top frame 203 is a circular frame, such as Fig. 9 An arc-shaped limiting groove 1041 is provided at a position of the head fixing frame 1 corresponding to the frame. The limiting groove 1041 is provided corresponding to the connecting top frame 203 , and the frame connected to the top frame 203 is rotatably connected in the limiting groove 1041 .

[0051] The connecting side plate 202 is an arc-shaped plate, the curvature of the connecting side plate 202 is the same as the curvature of the frame, and the curvature of the connecting top frame 203 is the same as the curvature of the connecting bottom plate 201. The connecting side plate 202 is made of non-metallic material, preferably, the connecting side plate 202 is an acrylic plate. The connecting side plate 202 can also be a plate body of other non-metallic material that does not affect scanning, which is not limited here. The connecting side plate 202 has the function of supporting and protecting.

[0052] In order to improve the structural strength of the connecting top frame 203, the frame is provided with a reinforcing rod 2031. In one embodiment, one reinforcing rod 2031 is provided, and the reinforcing rod 2031 is arranged along the diameter direction of the connecting top frame 203. In other embodiments, a plurality of reinforcing rods 2031 are provided, and different reinforcing rods 2031 are arranged in parallel or intersecting, and the plurality here refers to two or more.

[0053] When the CBCT detection bracket of the gastrointestinal machine of the utility model is working, the patient stands on the rotating frame 2, and the patient and the rotating frame 2 stably rotate along with the rotating foot pedal 4 of the gastrointestinal machine 5, thereby realizing the CBCT function of the gastrointestinal machine together with the ball tube and flat panel detector of the gastrointestinal machine. The gastrointestinal machine of the utility model can realize the CBCT function of the gastrointestinal machine by adding the CBCT detection bracket, which can greatly increase the value of the gastrointestinal machine and improve the diagnostic effect on patients.
