As shown in fig. 1 to 3, the disclosed embodiment of the present invention discloses an ultrasonic probe for performing ultrasonic diagnosis on a human body.

The ultrasonic probe includes: a main body 10, a probe body 20, and a damping mechanism 30. The main body 10 is provided for a doctor to handle, and the probe body 20 is provided in the main body 10 so as to be extendable and retractable with respect to the main body 10. The damping mechanism 30 is disposed between the main body 10 and the probe body 20 for enabling the probe body 20 to contact human tissue with a certain pre-tightening force. The damping mechanism 30 is used to extend and contract the probe body 20 with a certain degree of rigidity.

The probe body 20 is a working member for performing diagnosis.

The above-described embodiments of the present invention have the advantages that:

according to the invention, the probe body 20 is arranged on the main body part 10 in a telescopic manner relative to the main body part 10, and a certain rigidity is provided for the probe body 20 through the damping mechanism 30, so that the probe body 20 not only can form a certain contact force with human tissues 100 (such as armpits), but also when the transverse probe encounters human bones, the probe body 20 can hide the human bones through the telescopic manner.

In a preferred embodiment of the invention, the probe body 20 is provided at the front end of the main body 10; wherein the head of the probe body 20 forms a spherical surface. The spherical surface makes the probe body 20 more suitable for contacting human tissue having a deep socket.

By arranging the guide holes and the guide posts 40 and matching the guide posts 40 with the guide holes, the probe body 20 is strictly extended and contracted in the axial direction.

In a preferred embodiment of the present invention, the damping mechanism 30 includes an elastic member disposed in the guide hole to apply force to the probe body 20 in a direction toward the head of the probe body 20. Preferably, the elastic member is a spring 31; wherein: the guide post 40 is formed with a first step surface 41 facing the hole bottom direction of the guide hole; the spring 31 is sleeved on the guide post 40 and is located between the first step surface 41 and the hole bottom of the guide hole. Preferably, the damping mechanism 30 further includes an electromagnet 33 and a permanent magnet 32; wherein: the electromagnet 33 is arranged at the hole bottom of the guide hole, the permanent magnet 32 is arranged at the end part of the guide post 40 and is opposite to the electromagnet 33 or the permanent magnet 32 is arranged at the hole bottom of the guide hole, and the electromagnet 33 is arranged at the end part of the guide post 40 and is opposite to the permanent magnet 32; wherein: the magnetic repulsion between the electromagnet 33 and the permanent magnet 32 is changed by changing the current through the coil of the electromagnet 33.

The advantages of the above embodiment are:

by changing the current passing through the coil of the electromagnet 33, the magnetic repulsion is changed, and the expansion stiffness of the probe body 20 can be changed, and the maximum contact force that can be formed between the probe body 20 and the human tissue can be adjusted.

In a preferred embodiment of the invention, a retainer ring 70 is provided at the port of the guide hole; wherein: the guide post 40 is formed with a second step surface 42 facing the probe body 20, and the retainer ring 70 is adapted to abut against the second step surface 42. In this embodiment, the engagement of the retainer ring 70 with the second step surface 42 prevents the guide post 40 from being removed from the guide hole.

In a preferred embodiment of the present invention, the lower portion of the probe body 20 is sleeved with a first connection ring 61, and the upper portion of the main body 10 is sleeved with a second connection ring 62; wherein: the ultrasound probe further comprises a protective sheath 50 made of a flexible material; a first embedding groove 611 is formed on the outer circumferential surface of the first connecting ring 61, and a second embedding groove 621 is formed on the outer circumferential surface of the second connecting ring 62; a first annular protrusion 51 is formed on the inner wall of the upper port of the protective sleeve 50, the upper port of the protective sleeve 50 is sleeved on the first connecting ring 61, and the first annular protrusion 51 is embedded in the first embedding groove 611; the inner wall of the lower port of the protection sleeve 50 is formed with a second annular protrusion 52, the lower port of the protection sleeve 50 is sleeved on the second connection ring 62, and the second annular protrusion 52 is embedded in the second embedding groove 621. The intermediate portion of the protective sheath 50 is formed with a telescoping bend 53 to allow the axial dimension of the protective sheath 50 to be adjusted. Preferably, the retaining sleeve is made of silicone.

The advantages of the above embodiment are:

1. the protective cover 50 can effectively prevent foreign substances from entering into the body 10.

2. The protective sleeve 50 can extend and retract along with the probe body 20 by arranging the bending part 53, so that the probe body 20 is prevented from being limited to extend and retract.
