[0030] The present application provides a probe assembly of an open-type SPECT device and a SPECT device including the probe assembly.

[0031] The structure of the probe assembly of the open SPECT device in a specific embodiment is described below in conjunction with the accompanying drawings. It should be understood that the accompanying drawings and the following description are only examples and are not intended to limit the scope of protection of this application.

[0032] like Figure 1 As shown, the present application provides a probe assembly of an open-type SPECT device and a SPECT device including the probe assembly. The probe assembly of the open-type SPECT device includes: a probe bracket 1, the probe bracket 1 is arc-shaped, and the probe bracket 1 is provided with an arc-shaped guide rail 2; a connecting member 4, the connecting member 4 is slidably connected to the arc-shaped guide rail 2 through a slider 3; a probe body 5, which is installed on a first side of the connecting member 4 and can rotate around an axis S relative to the connecting member 4; a first driving mechanism, which is used to drive the connecting member 4 to slide along the arc-shaped guide rail 2 relative to the probe bracket 1; and a second driving mechanism, which is used to drive the connecting member 4 to rotate around the axis.

[0033] By adopting the structure of the probe assembly, under the driving action of the first driving mechanism, the probe body 5 can slide along the arc guide rail 2 with the connecting member 4 to change the position of the probe body 5, and under the driving action of the second driving mechanism, the probe body 5 can rotate relative to the connecting member 4 to change the angle of the probe body 5. The structure is simple and easy to use, thereby well meeting the needs of the open SPECT device to flexibly adjust the probe position and angle, and can more conveniently collect scanning data. The first driving mechanism and the second driving mechanism can be controlled by a remote controller, or the control buttons or control panels of the first driving mechanism and the second driving mechanism can be directly set on the SPECT device. By controlling the first driving mechanism and the second driving mechanism, the position of the probe body 5 in the SPECT device and the rotation angle of the probe body 5 can be conveniently controlled. By adopting the structure of the probe assembly, the various components therein can be easily repaired and replaced, which has greater flexibility compared to traditional SPECT devices.

[0034] like Figure 1 As shown, in this embodiment, the upper and lower sides of the probe holder 1 are respectively provided with an arc guide rail 2, and the screw rod 7 is located between the arc guide rail 2 on the upper side and the arc guide rail 2 on the lower side. The first driving mechanism includes a first motor 8 and a screw rod 7. The first motor 8 is a screw motor with a nut inside. The first motor 8 includes a housing, a stator, a rotor and a nut arranged inside the housing. The rotor drives the nut to rotate. The nut is sleeved on the outside of the screw rod 7 and is threadedly matched with the screw rod 7. The housing of the first motor 8 is fixed to the second side of the connecting member 4. The screw rod 7 is an arc screw rod 7, and the screw rod 7 is arranged parallel to the arc guide rail 2. Through the cooperation of the nut and the screw rod 7, the rotational motion output by the first motor 8 is converted into the arc motion of the connecting member 4 along the screw rod 7.

[0035] In this embodiment, the upper and lower ends of the connecting member 4 are slidably connected to the arc guide rail 2 through the slider 3. The slider 3 is provided with a groove on one side facing the arc guide rail 2, and the arc guide rail 2 is embedded in the groove of the slider 3, so that the slider 3 can slide along the arc guide rail 2, and the arc motion of the connecting member 4 is guided by the cooperation of the slider 3 and the arc guide rail 2. By respectively arranging the sliders 3 cooperating with the arc guide rail 2 at the upper and lower ends of the connecting member 4, the upper and lower ends of the connecting member 4 can be well guided, so that when the connecting member 4 slides along the screw 7, the connecting member 4 will not rotate or tilt relative to the screw 7, and the stable cooperation between the connecting member 4 and the first motor 8 and the screw 7 is maintained. By controlling the rotation speed of the rotor of the first motor 8, the speed of the connecting member 4 and the probe body 5 moving along the screw 7 can be adjusted, and by controlling the rotation direction and angle of the rotor of the first motor 8, the direction and angle of the movement of the connecting member 4 and the probe body 5 along the screw 7 can be adjusted.

[0036] like Figure 1 As shown, in this embodiment, the axis S is parallel to the length direction of the connecting member 4, that is, Figure 1 The two ends of the probe body 5 are rotatably connected to the two ends of the connecting member 4. Specifically, the second driving mechanism includes a second motor 9, the output shaft of the second motor 9 is parallel to the axis, and the output shaft of the second motor 9 is connected to the lower end of the probe body 5 through a coupling 6. The upper end of the probe body 5 is connected to the connecting member 4 through a bearing 10. After the second motor 9 is started, the output shaft of the second motor 9 transmits the rotational motion to the probe body 5 through the coupling 6, so that the probe body 5 can rotate around the axis relative to the connecting member 4. The upper end of the probe body 5 is connected to the connecting member 4 through a bearing 10, so that when the probe body 5 rotates, the connecting member 4 will not rotate relative to the probe bracket 1. By controlling the rotation speed of the output shaft of the second motor 9, the speed of the probe body 5 rotating around the axis S can be adjusted, and by controlling the rotation direction and angle of the output shaft of the second motor 9, the direction and angle of the probe body 5 rotating around the axis S can be adjusted.

[0037] In another embodiment, the probe assembly may include a plurality of connectors 4 and a plurality of probe bodies 5, each of which is respectively mounted with a probe body 5, and the plurality of connectors 4 are arranged in parallel with each other, each of which is respectively driven by a first motor 8 to slide along the arc guide rail 2, and each of which is respectively rotated around an axis by a second motor 9, that is, the connector 4 corresponds to the probe body 5 one by one, the connector 4 corresponds to the first motor 8 one by one, and the probe body 5 corresponds to the second motor 9 one by one. Optionally, the plurality of connectors 4 are evenly arranged along the extension direction of the screw 7, and scanning and data acquisition can be performed evenly. In practical applications, the number of probe bodies 5 can be selected as needed, and can be increased or decreased according to different needs. For each probe body 5, its position on the probe holder 1 and its rotation angle relative to the probe holder 1 can be individually controlled to achieve flexible control of the probe assembly and meet various different data acquisition requirements.
