Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0030] Referring to Figures 1-7 As shown in the drawings, the present application provides an ultrasonic probe, which comprises a shell 1 provided with a containing space 6 and a probe body 2 slidably connected in the shell 1 through a sliding assembly 3, the scanning end of the probe body 2 extends out of the containing space 6, a clamping assembly 4 is connected between the probe body 2 and the shell 1, when the ultrasonic probe is in a powered state, the clamping assembly 4 is in a clamping state to prevent the probe body 2 from sliding along the length direction of the probe body 2, when the ultrasonic probe is in a powered-off state, the clamping assembly 4 is in a separated state to enable the probe body 2 to slide along the length direction of the probe body 2.

[0031] The ultrasonic probe described above, when a robot is used to control the ultrasonic probe to examine a patient, if a sudden power-off situation occurs, the clamping assembly 4 will be in a separated state, at this time the mechanical arm continues to move forward under the action of inertia, the probe body 2 is extruded by the mechanical arm and the patient to slide into the containing space 6 to reduce the extrusion on the patient, thereby reducing the possibility of injury to the patient.

[0032] In some embodiments, referring to Figures 2-6The clamping assembly 4 comprises a clamping piece 41 connected to the probe body 2 and a connecting seat 42 connected to the shell 1. One side of the clamping piece 41 facing the connecting seat 42 is provided with a protrusion 411, and one side of the connecting seat 42 facing the probe body 2 is provided with a clamping groove 421 adapted to clamp the protrusion 411. The clamping assembly 4 of the present application is clamped by the mutual clamping of the protrusion 411 of the clamping piece 41 and the clamping groove 421 of the connecting seat 42. When the ultrasonic probe is powered on, the protrusion 411 is located in the clamping groove 421. When the ultrasonic probe is powered off, the protrusion 411 is separated from the clamping groove 421. In some embodiments, the protrusion 411 can also be provided on the connecting seat 42, and the clamping groove 421 is correspondingly provided on the clamping piece 41, as long as the probe body 2 can be clamped with the shell 1 when powered on and separated from the shell 1 when powered off.

[0033] In some embodiments, referring to Figures 2-6 , when the protrusion 411 is provided on the clamping piece 41, the clamping assembly 4 further comprises a clamping seat 7 connected to the probe body 2 and an electromagnet 8 located below the connecting seat 42. The clamping piece 41 is connected to the clamping seat 7 through a first elastic piece 9, and the electromagnet 8 is adapted to attract the clamping piece 41 to clamp the protrusion 411 with the clamping groove 421.
