Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically an angle-adjustable ultrasound probe. Background Technology
[0002] An ultrasound probe is used to send and receive ultrasound waves reflected from the human body. The ultrasound waves emitted by the probe are attenuated by the body tissues and then reflected back to the probe.
[0003] In preoperative and postoperative examinations, existing equipment uses an ultrasound head fixed to the device for monitoring. During treatment, the ultrasound used for monitoring generally needs to be adjusted to the optimal position for monitoring and fixed to the device. However, existing ultrasounds on the market cannot be adjusted in angle. If adjustment is required, a specific structure needs to be designed and the ultrasound head fixed to that structure.
[0004] Chinese Publication No. CN 214318875 U discloses an angle-adjustable ultrasound device, comprising a transducer, a rotating shaft, a clutch, a rear housing, and a cable tail sleeve. The front end of the rotating shaft is fixedly connected to the transducer, and the central axis of the rotating shaft coincides with the central axis of the transducer's imaging detection surface. The clutch, rear housing, and cable tail sleeve are sequentially mounted on the rear end of the rotating shaft. The clutch employs a toothed interlocking clutch structure for locking and unlocking the rotating shaft. The rear housing is mounted on the rotating shaft via bearings. The cable tail sleeve is detachably and fixedly connected to the rear end of the rotating shaft. This invention solves the problem of ordinary ultrasound devices being unable to adjust angles: through a special structural design, it can precisely rotate and adjust the required monitoring angle around the central axis of the ultrasound imaging detection surface and can quickly lock; moreover, it can be quickly assembled and disassembled on focused ultrasound treatment equipment, saving one ultrasound probe required during treatment.
[0005] In the above solution, the locking structure of the clutch does not limit the rotation angle, meaning the probe can rotate arbitrarily multiple times. This would cause excessive twisting of the cable at the back end of the ultrasound machine. Furthermore, the cable end sleeve serves to press against the rear shell, and the cable end sleeve needs to rotate synchronously with the rotating shaft. The squeezing and friction between the cable end sleeve and the rear shell would affect the rotation of the rotating shaft. Based on this, an ultrasound probe with adjustable angle is provided.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1-5 In this embodiment of the present invention, an angle-adjustable ultrasound probe includes a probe assembly 1 consisting of a probe body 101, a rotating shaft 102, a concave groove 103, and a cable 104, and an adjustment assembly 2.

Multiple positioning blocks 2042 are provided, and the multiple positioning blocks 2042 are fixed to the rear end of the ring tooth seat 2041 in a ring.
[0045] The clamping plate 2052 is fixed to the inner side of the front end of the outer shell 2051, and the positioning groove 2053 is opened at the front end of the clamping plate 2052 and completely penetrates the rear end of the clamping plate 2052.
[0046] The annular gear seat 2041 is sleeved on the outside of the positioning cylinder shaft 1022. The outer shell body 2051 is attached to the rear end of the annular gear seat 2041 through the clamping plate 2052.

[0047] The clamping component 206 includes a clamping seat 2061, a through hole 2062, a clamping hole 2063, and a ball bearing 2064;
[0048] Through hole 2062 and clamping hole 2063 are respectively opened at the front and rear ends of clamping seat 2061, and through hole 2062 and clamping hole 2063 are connected. Ball 2064 is rolled and connected to the inner side of clamping seat 2061 and distributed at the junction of through hole 2062 and clamping hole 2063. Ball 2064 protrudes from the inner side of through hole 2062 and clamping hole 2063.
[0049] The clamping seat 2061 is clamped to the rear end of the outer shell body 2051. The connecting cylinder shaft 1023 extends through the through hole 2062 to the inside of the clamping hole 2063. The cable tail sleeve 207 extends into the inside of the clamping hole 2063.

[0050] An annular groove is provided inside the clamping seat 2061 at the position where it contacts the ball 2064, allowing the ball 2064 to roll. Multiple balls 2064 are evenly arranged along the circumference, and the inner diameter of the multiple balls 2064 matches the outer diameter of the connecting cylinder shaft 1023.
[0051] In this embodiment: the angle adjustment operation of this ultrasound probe is as follows:
[0052] By pushing the rotary switch 201 towards the probe body 101, the rotary switch 201 compresses the spring 202 and simultaneously causes the arc-shaped locking block 203 to separate from the ring tooth seat 2041. At this time, the locking of the probe assembly 1 is released, so the probe assembly 1 and the rotary switch 201 can be rotated as a whole, thereby realizing the angle adjustment of the probe body 101.
[0053] After adjusting to the required angle, release the push on the rotary switch 201. At this time, the rotary switch 201 is reset under the elastic force of the spring 202 and pushes the arc-shaped locking block 203 to engage with the ring tooth seat 2041, thus locking the angle of the probe body 101. During this process, the limiting protrusion 2043 limits the rotation angle of the arc-shaped locking block 203, so that the maximum rotation angle of the arc-shaped locking block 203 is 180 degrees. That is, while meeting the angle adjustment requirements of the probe body 101, it also avoids the probe body 101 from rotating multiple times, causing the cable 104 to twist and deform too much.
[0054] In addition, when the probe assembly 1 is adjusted in angle, the cable tail sleeve 207 rotates synchronously with the rotating shaft 102. Its ball bearings 2064 can provide support for the rotation of the cable tail sleeve 207 and the connecting cylinder shaft 1023. At the same time, the rolling of the ball bearings 2064 can also reduce the rotational resistance of the cable tail sleeve 207, making the angle adjustment of the probe assembly 1 easier.
[0055] Please refer to this carefully. Figures 2-4The outer diameters of the front cylindrical shaft 1021, the positioning cylindrical shaft 1022, and the connecting cylindrical shaft 1023 decrease sequentially.
[0056] In this embodiment, the structure of the front cylinder shaft 1021, the positioning cylinder shaft 1022, and the connecting cylinder shaft 1023 with decreasing outer diameters in sequence not only enables convenient installation of the adjustment component 2, but also provides a limit for the horizontal direction of the brake component 204.
[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
