Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic scanners, in particular to a scanner with a protective structure. Background Art

[0002] Medical ultrasonic scanners are medical devices developed based on the principle of ultrasound and used in the medical and health field to diagnose and treat diseases. Ultrasound refers to sound waves with a frequency higher than 20,000 Hz that cannot be heard by humans. It has the characteristics of good directionality and strong penetration. The working principle of medical ultrasonic examination is similar to that of sonar, that is, ultrasound is emitted into the human body. When it encounters an interface in the body, it will be reflected and refracted, and it may be absorbed and attenuated in human tissues. Because the morphology and structure of various tissues in the human body are different, the degree of reflection, refraction and absorption of ultrasound is also different. Doctors distinguish them through the wave pattern, curve, or image characteristics reflected by the instrument. In addition, combined with anatomical knowledge, normal and pathological changes, they can diagnose whether the examined organ is normal.

[0003] Medical ultrasonic scanners mainly consist of two parts, namely the main unit and the ultrasonic probe. The main unit of the ultrasonic diagnostic instrument mainly processes and displays the signals received from the probe. The ultrasonic probe can transmit and receive ultrasound, perform electroacoustic signal conversion, convert the electrical signal sent by the main unit into a high-frequency oscillating ultrasonic signal, and convert the ultrasonic signal reflected from the tissues and organs into an electrical signal and display it on the display of the main unit.

[0004] During the use of an ultrasonic scanner, the ultrasonic probe is in an unprotected state when it is idle. The ultrasonic probe is a precision mechanical product. When the ultrasonic probe is idle and not in use, external bumps may cause damage to the ultrasonic probe. Therefore, a protective device is required to protect the ultrasonic probe. Based on this, a scanner with a protective structure is provided. Utility Model Content

[0030] The protection component 2 includes a protection unit, a linkage guide unit and a reset unit;

[0031] The protection unit in the unfolded state is away from the front end of the ultrasonic probe 1 and does not affect the use of the ultrasonic probe 1. The retracted protection unit moves forward to wrap the front end of the ultrasonic probe 1 to protect the front end of the ultrasonic probe 1.

[0032] The linkage guide unit is used to guide and limit the movement of the protection unit, and is used to realize the expansion and contraction of the protection unit;

[0033] The reset unit is used to provide power for the deployment and reset of the protection unit;

[0034] The protection unit includes an arc-shaped protection cover 201 and a side protection plate 202;

[0035] The side guard plates 202 are symmetrically fixed on both sides of the arc-shaped protective cover 201;

[0036] There are two arc-shaped protective covers 201, which are symmetrically distributed up and down with the ultrasonic probe 1 as the center and do not contact the ultrasonic probe 1. The side guard plates 202 are distributed on both sides of the outside of the ultrasonic probe 1.

[0037] The arc-shaped protective covers 201 that are far away from each other are distributed at the upper and lower ends of the ultrasonic probe 1 and are far away from the front end of the ultrasonic probe 1, so as not to affect the use of the ultrasonic probe 1;

[0038] The contact position of the arc-shaped protective covers 201 close to each other is located in front of the front end of the ultrasonic probe 1, so as to shield and protect the front end of the ultrasonic probe 1;

[0039] The linkage guide unit includes an inclined guide groove 203, a limiting guide column 204, a vertical slide groove 205 and a return-shaped sliding frame 206;

[0040] The inclined guide groove 203 is symmetrically arranged on both sides of the front end of the ultrasonic probe 1, and the limiting guide post 204 is fixed to the side of the side guard plate 202 close to the ultrasonic probe 1 and is slidably connected to the inner side of the inclined guide groove 203. The inclined guide groove 203 and the limiting guide post 204 cooperate to guide the movement of the arc-shaped protective cover 201 and the side guard plate 202.

[0041] The vertical slide groove 205 is opened inside the side guard plate 202 and passes through both sides of the side guard plate 202. The return-shaped sliding frame 206 is sleeved and slid on the outer side of the front end of the ultrasonic probe 1, and the side part of the return-shaped sliding frame 206 is slidably connected to the inside of the two vertical slide grooves 205 distributed up and down. The cooperation between the vertical slide groove 205 and the return-shaped sliding frame 206 allows the movement of the side guard plates 202 distributed up and down to be synchronized.

[0042] The reset unit includes a Z-shaped spring piece 207, which is symmetrically bonded and fixed to the upper and lower ends of the circular sliding frame 206, and the other end of the Z-shaped spring piece 207 is in contact with the inner wall of the arc-shaped protective cover 201. When the two arc-shaped protective covers 201 approach each other, the Z-shaped spring piece 207 is squeezed to shrink, and the shrinking Z-shaped spring piece 207 is used to provide power for the reset of the arc-shaped protective cover 201.

[0043] In this embodiment: when the ultrasonic probe 1 is held for inspection, the arc-shaped protective cover 201 does not receive external squeezing force, and its Z-shaped spring piece 207 can keep the two arc-shaped protective covers 201 away from each other, and the ends of the arc-shaped protective cover 201 are located at the upper and lower ends of the front end of the ultrasonic probe 1, so that the front end of the ultrasonic probe 1 is exposed, and this area is the detection working area, so that the inspection operation can be conveniently performed. At the same time, the front end of the arc-shaped protective cover 201 is an arc-shaped structure. When performing ultrasonic inspection, the arc-shaped protective cover 201 will not contact the human body during the swing and movement of the ultrasonic probe 1, thereby ensuring the normal operation of the inspection;

[0044] When the ultrasonic probe 1 is placed idle on the workbench, one of the arc-shaped protective covers 201 faces the workbench surface. During the placement process, the arc-shaped protective cover 201 will contact the workbench surface. At this time, under the action of the ultrasonic probe 1's own gravity, the arc-shaped protective cover 201 will be subjected to an upward squeezing force, which can push the arc-shaped protective cover 201 and the side guard plate 202 and the limiting guide column 204 connected thereto to move synchronously. The limiting guide column 204 moves along the track of the corresponding inclined guide groove 203, so that the moving track of the arc-shaped protective cover 201 is inclined upward;

[0045] At the same time, the movement of the arc-shaped protective cover 201 can synchronously drive the return-shaped sliding frame 206 to move horizontally, and the return-shaped sliding frame 206 will drive another arc-shaped protective cover 201 to move, and the other arc-shaped protective cover 201 moves along another set of inclined guide grooves 203, and the movement trajectory of the other arc-shaped protective cover 201 is inclined downward;

[0046] Finally, the front ends of the two arc-shaped protective covers 201 are moved in front of the front end of the ultrasonic probe 1, and the front ends of the two arc-shaped protective covers 201 are fitted together, that is, the front end of the ultrasonic probe 1 is wrapped inside the two arc-shaped protective covers 201, so that external objects cannot contact the front end of the ultrasonic probe 1, effectively avoiding collision damage to the front end of the ultrasonic probe 1 when taking other items on the workbench.

[0047] Please refer to Figures 1 to 3 Two groups of inclined guide grooves 203 are arranged on the side of the outer wall of the ultrasonic probe 1, and each group includes two inclined guide grooves 203. The two inclined guide grooves 203 in each group of inclined guide grooves 203 are flush in the horizontal direction, and the upper and lower groups of inclined guide grooves 203 are symmetrical and staggered in the vertical direction. The two side guard plates 202 distributed upper and lower are each provided with two limiting guide pillars 204, and the positions of the limiting guide pillars 204 distributed upper and lower correspond to the two groups of inclined guide grooves 203 respectively.

[0048] In this embodiment, two sets of symmetrical and staggered inclined guide grooves 203 are arranged so that the upper and lower limit guide pillars 204 do not interfere with each other when moving along the track of the inclined guide grooves 203.

[0049] Through the cooperation structure of the two limiting guide pillars 204 and the two inclined guide grooves 203, the movement of the arc-shaped protective cover 201 can be made more stable and the deflection phenomenon can be avoided.

[0050] Please refer to Figures 1 to 3 A plurality of Z-shaped spring pieces 207 are evenly arranged along the track of the horizontal portion of the return-shaped sliding frame 206 , and the total elastic force of the plurality of Z-shaped spring pieces 207 is less than the self-weight of the ultrasonic probe 1 .

[0051] In this embodiment, the structural arrangement of the multiple Z-shaped spring pieces 207 makes the contraction movement of the arc-shaped protective cover 201 more stable, and can also buffer the impact force of the ultrasonic probe 1 placed on the workbench.

[0052] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
