[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] See also Figure 1-5As shown, this embodiment is a photoacoustic detection device for tumor cells, comprising:

[0036] A housing 11 vertically arranged on a horizontal plane;

[0037] The top of the housing 11 is fixedly connected to a workbench 12, the bottom of the housing 11 is fixedly connected to a base 13, the top of the workbench 12 is fixedly connected to a frame 14, and the interior of the housing 11 is slidably connected to a photoacoustic detector 15;

[0038] The workbench 12 is used as a space for medical personnel to operate. The photoacoustic detector 15 can image the observed object in a short time and its non-destructive nature to the original object makes this technology better serve the diagnosis of cancer patients. The photoacoustic detector 15 irradiates the tissue with pulsed laser. After the tissue absorbs the light, it generates thermal expansion and ultrasonic waves. The ultrasonic waves are received by the ultrasonic transducer and the image is reconstructed.

[0039] Protection assembly: The protection assembly includes a motor 21, a protective cover 22, a rotating shaft 23, a guide frame 24, a rotating rod 25, a first bevel gear 26, a second bevel gear 27, a sleeve 28, a fixing block 29; and a rotating gear 210;

[0040] The motor 21 is fixedly connected to one side of the housing 11, the first bevel gear 26 is fixedly connected to one end of the motor 21, the rotating rod 25 is rotatably connected to the top of the base 13, the guide frame 24 is fixedly connected to the inside of the housing 11, the second bevel gear 27 is fixedly connected to the outside of the rotating rod 25, the sleeve 28 is fixedly connected to the bottom end of the photoacoustic detector 15, the fixing block 29 is fixedly connected to the top of the photoacoustic detector 15, the rotating shaft 23 is rotatably connected to both sides of the top of the frame 14, and the rotating gear 210 is fixedly connected to one end of the rotating shaft 23;

[0041] The output shaft of the motor 21 is mounted with a first bevel gear 26 via a coupling. The guide frame 24 is used to provide a space for the rotating rod 25 to rotate and to provide a guide trajectory for the sleeve 28 to move upward and downward, thereby providing power for the photoacoustic detector 15 to move upward and downward and power for the protective cover 22 to flip over.

[0042] Through the auxiliary cooperation between the motor 21 and the rotating rod 25, the sleeve 28 on the same central axis can be raised and lowered along the threaded track of the rotating rod 25, which can retract and protect the photoacoustic detector 15 and extend the service life of the photoacoustic detector 15. At the same time, through the auxiliary cooperation between the fixed block 29 and the rotating gear 210, the protective cover 22 can be turned over while the photoacoustic detector 15 rises, which can facilitate medical personnel to quickly use the device;

[0043] Working principle: When medical staff use the photoacoustic detection device;

[0044] First, the medical staff starts the motor 21 to rotate the rotating rod 25. Since the sleeve 28 and the guide frame 24 are arranged on the same central axis, the sleeve 28 can be guided upward along the thread track of the rotating rod 25, thereby allowing the photoacoustic detector 15 to slide upward and extend into the interior of the frame 14.

[0045] Next, the fixed block 29 is slid upward, which can rotate the rotating gear 210, thereby rotating the rotating shaft 23, and causing the protective cover 22 to flip horizontally by 90°, thereby releasing the protection formed on the front end of the photoacoustic detector 15.

[0046] See also Figure 1-5 As shown, this embodiment is based on the above embodiment 1 and also includes a storage component;

[0047] The storage assembly includes a storage box 31, a spring plate 32, a spring block 33, and a spring buckle 34;

[0048] The storage box 31 is fixedly connected to one end of the inner wall of the protective cover 22, the spring plate 32 is slidably connected to one side of the front end of the protective cover 22, the spring buckle 34 is fixedly connected to the upper part of one side of the spring plate 32, and the spring block 33 is slidably connected to the upper part of the front end of the protective cover 22;

[0049] The storage box 31 is used to provide storage space for medical devices. The spring plate 32 is used to provide a protective shielding function for the storage box 31. The spring buckle 34 is used to limit the spring plate 32. The spring block 33 can release the limit formed on the spring plate 32.

[0050] Through the auxiliary cooperation between the spring block 33 and the spring buckle 34, the two sets of spring plates 32 can slide in opposite directions to each other, thereby releasing the protection formed on the storage box 31, making it easier for medical staff to store and take out medical equipment;

[0051] Working principle: When medical staff use the device;

[0052] First, the medical staff can release the engagement formed by the spring buckle 34 by pressing the spring block 33, thereby causing the two sets of spring plates 32 to slide in opposite directions;

[0053] Next, the blocking formed on the storage box 31 is released to facilitate medical personnel to store the medical equipment.
