Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a solid coupling agent component. Background Art

[0002] At present, during B-ultrasound examination or ultrasound treatment, the presence of air between the ultrasound probe and the skin prevents the ultrasound waves emitted by the ultrasound probe from passing through the skin and entering the human body, so medical ultrasound coupling agents have come into being. In some three-dimensional ultrasound scanning systems, due to the structure of the mechanical arm, a large gap is easily generated between the probe and the skin, and liquid coupling agents cannot fill the gap, so solid coupling agents are often used.

[0003] However, solid coupling agents are not easy to fix to the probe and are easy to slip off the skin or produce displacement deviations. Therefore, during the use of solid coupling agents, the position of the solid coupling agents needs to be corrected multiple times, thereby reducing the efficiency of medical staff in performing ultrasound scanning.

[0004] In summary, how to improve the ultrasonic scanning efficiency of solid coupling agents is an urgent problem to be solved. Utility Model Content

[0037] A solid coupling agent assembly provided in an embodiment of the present application can improve the ultrasonic scanning efficiency of the solid coupling agent.

[0038] Figure 1 A schematic partial structural diagram of a solid coupling agent assembly provided in an embodiment of the present application, see Figure 1 The present application provides a solid coupling agent assembly, including a coupling sleeve 1 and a fastening assembly 2.

[0039] Exemplarily, the coupling sleeve 1 is used to couple an ultrasonic probe. A receiving groove 11 is provided on the coupling sleeve 1. The receiving groove 11 corresponds to the groove wall of the coupling sleeve 1 and is used to mount the ultrasonic probe. The coupling sleeve 1 is elastic and can be better adapted to fit the skin. The coupling sleeve 1 is made of, for example, elastic material.

[0040] In some examples, the accommodating groove 11 forms an accommodating space on the coupling sleeve 1, the ultrasonic probe is placed in the accommodating space, and part of the groove wall of the accommodating groove 11 fits or abuts the detection end of the ultrasonic probe, while part of the groove wall of the accommodating groove 11 fits the wall surface of the ultrasonic probe.

[0041] It is understandable that the material of the coupling sleeve 1 is a material that can couple ultrasound into the skin. In the art, for example, the coupling sleeve 1 is made of a solid coupling agent, and thus the coupling effect of the coupling sleeve 1 of the present application on ultrasound is more ideal.

[0042] Exemplarily, the fastening assembly 2 is detachably mounted on the coupling sleeve 1 , and the fastening assembly 2 is arranged corresponding to the receiving groove 11 .

[0043] In some examples, the fastening component 2 can be squeezed from the outside of the coupling sleeve 1 toward the inside thereof. For example, the fastening component 2 is a binding strap, and the size of the limiting hole surrounded by the fastening component 2 can be fixed by tying a knot, so that the groove wall size of the accommodating groove 11 at the corresponding position is retracted by the fastening component 2, so that the accommodating groove 11 fits or abuts against the ultrasonic probe.

[0044] Exemplarily, the fastening assembly 2 can also be interference-fitted to the coupling sleeve 1 .

[0045] In some examples, the size of the frame formed by the fastening component 2 is smaller than the size of the wall of the coupling sleeve 1 that fits the fastening component 2, so that the wall of the corresponding part of the coupling sleeve 1 is pressed against the ultrasonic probe. At the same time, the force generated by the interference fit is greater than the force generated by the transition fit, and after the fastening component 2 completes the fixing operation, the coupling sleeve 1 is difficult to separate from the fastening component 2.

[0046] In summary, the fastening assembly 2 of the present application is a structure capable of adjusting the size. By limiting the size of the accommodating groove 11 through the fastening assembly 2, a portion of the ultrasonic probe can be further confined in the accommodating groove 11, making it difficult for the ultrasonic probe to separate from the accommodating groove 11.

[0047] The fastening component 2 can act on the part of the coupling sleeve 1 corresponding to the accommodating groove 11, so that the size of the accommodating groove 11 is reduced, and the pressure on the coupling sleeve 1 is increased, so that the coupling sleeve 1 is easier to abut against the ultrasonic probe, and based on the pressure of the fastening component 2, the friction between the groove wall of the accommodating groove 11 and the ultrasonic probe is increased, and the ultrasonic probe is not easy to produce relative displacement with the accommodating groove 11. Therefore, the present application does not need to adjust the position of the coupling sleeve 1, so that the efficiency of the ultrasonic detection operation is higher.

[0048] The fastening component 2 is interference-fitted with the coupling sleeve 1 , so that the extrusion effect of the fastening component 2 can also avoid deformation caused by deformation of other positions of the coupling sleeve 1 , thereby achieving a better fastening effect of the fastening component 2 .

[0049] Exemplarily, the fastening assembly 2 includes a first limit member 21 and a second limit member 22, wherein the second limit member 22 is detachably connected to the first limit member 21, and when the first limit member 21 and the second limit member 22 are connected, the first limit member 21 and the second limit member 22 can enclose a limit hole for interference fit with the coupling sleeve 1.

[0050] Exemplarily, the cross-sectional area of ​​the limiting hole is adjustable.

[0051] In some examples, the cross-sectional area of ​​the limiting hole is limited by the first limiting member 21 and the second limiting member 22, that is, the connection between the first limiting member 21 and the second limiting member 22 is adjustable, and different lengths, widths or diameters of the limiting hole can be achieved by adjusting the relative positions of the first limiting member 21 and the second limiting member 22, so that the fastening assembly 2 of the present application is suitable for a variety of usage scenarios.

[0052] Exemplarily, the first limiting member 21 and the second limiting member 22 are an integrated structure, such as a clamp, and a detachable connection structure is formed by the two ends of the clamp, and the clamp is tightened by bolts to achieve an interference fit between the fastening component 2 and the coupling sleeve 1.

[0053] Exemplarily, the first limiting member 21 and the second limiting member 22 are split structures, the first limiting member 21 is provided with a latch 211 , the second limiting member 22 is provided with a plurality of pin slots 221 , and the latch 211 is detachably engaged in the pin slots 221 .

[0054] In some examples, Figure 2 A schematic top view of a solid coupling agent assembly provided in an embodiment of the present application is shown in FIG. Figure 2As shown, the portion of the accommodating groove 11 corresponding to the coupling sleeve 1 is a block structure, that is, the cross-sectional area of ​​the portion corresponding to the coupling sleeve 1 is rectangular, the first stopper 21 and the second stopper 22 are bent structures forming a right angle, that is, the first stopper 21 and the second stopper 22 respectively include a right angle and two sides forming a right angle, a latch 211 is provided on the two sides of the first stopper 21, and a plurality of pin grooves 221 are provided on the two sides of the second stopper 22, and the plurality of pin grooves 221 correspond to the latch 211 one by one, thereby, by placing the latches 211 of the two sides of the first stopper 21 in the corresponding pin grooves 221 of the second stopper 22, the first stopper 21 and the second stopper 22 are connected, and the length distance and width distance in the cross section of the stopper hole can be fixed. In some examples, the number of the latches 211 can be set to be multiple, so as to facilitate the adjustment of the length and width of the stopper hole. In some examples, a latch 211 and a pin slot 221 may be respectively provided on two sides of the first limiting member 21, and a pin slot 221 and a latch 211 at corresponding positions may be provided on two sides of the second limiting member 22. In this example, the number of latches 211 on any side may be set to one.

[0055] In some examples, such as Figure 2 As shown, the portion of the accommodating groove 11 corresponding to the coupling sleeve 1 is a block-shaped structure, and the first limiting member 21 includes, for example, a first limiting segment, a first connecting segment, and a second connecting segment, and the two ends of the first limiting segment are respectively connected to the first connecting segment and the second connecting segment, and the connection may be a right angle, so that the first connecting segment and the second connecting segment are arranged relative to each other. The second limiting member 22 includes, for example, a second limiting segment, a third connecting segment, and a fourth connecting segment, and the two ends of the second limiting segment are respectively connected to the third connecting segment and the fourth connecting segment, and the connection may be a right angle, so that the third connecting segment and the fourth connecting segment are arranged relative to each other.

[0056] In such Figure 2 In the example shown, the lengths of the first limiting segment and the second limiting segment along the first direction are less than or equal to the length of the coupling sleeve 1 along the first direction, the first connecting segment and the second connecting segment are respectively provided with latches 211, and the third connecting segment and the fourth connecting segment are respectively provided with a plurality of pin grooves 221, and the plurality of pin grooves 221 are arranged along the second direction, and the latches 211 are connected with different pin grooves 221 in the second direction to adjust the length of the limiting hole along the second direction, thereby changing the size of the cross-sectional area of ​​the limiting hole, and then when the length of the limiting hole along the second direction is less than the length of the coupling sleeve 1 along the second direction, the first limiting member 21 and the second limiting member 22 can be interference fit in the coupling sleeve 1.

[0057] In some examples, since the coupling sleeve 1 is elastic, the length of the limiting hole along the second direction will continue to be reduced on the basis of the interference fit, so that the connection between the fastening component 2 and the coupling sleeve 1 has a smaller deformation amount. The coupling sleeve 1 will deform after contacting the skin, and it is less likely to cause the connection between the fastening component 2 and the coupling sleeve 1 to deform.

[0058] Exemplarily, the connected first limiting member 21 and the second limiting member 22 form an equal-height structure.

[0059] Exemplarily, the fastening component 2 is made of plastic material or rubber material.

[0060] In some examples, the fastening component 2 is made of hard plastic, for example, and the coupling sleeve 1 is made of silicone, for example, and the fastening component 2 can still squeeze the coupling sleeve 1 well.

[0061] Exemplarily, the hardness of the fastening component 2 is greater than the hardness of the coupling sleeve 1 .

[0062] In some examples, the fastening component 2 has a greater hardness and can better squeeze the coupling sleeve 1 and produce a smaller deformation, thereby improving the fixing effect of the fastening component 2 .

[0063] Exemplarily, the coupling sleeve 1 includes a fastening section 113 and a coupling section 111. The notch of the accommodating groove 11 is located at one end of the fastening section 113, the coupling section 111 is connected to the other end of the fastening section 113, and the bottom of the accommodating groove 11 is located in the coupling section 111. The fastening assembly 2 is detachably sleeved on the fastening section 113, and the coupling section 111 is used to correspond to the detection end of the ultrasound probe.

[0064] In some examples, Figure 3 A schematic side view of a solid coupling agent assembly provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, at least the detection end of the ultrasonic probe is located in the receiving groove 11, and the detection end is covered by the coupling section 111. The detection direction of the ultrasonic probe is along the opening of the receiving groove 11 to the bottom of the groove. Therefore, the coupling section 111 located at the bottom of the groove can better receive the ultrasonic wave emitted by the detection end to complete the detection operation.

[0065] Exemplarily, there is a smooth transition between the fastening section 113 and the coupling section 111 .

[0066] In some examples, both the inner wall surface and the outer wall surface of the coupling sleeve 1 corresponding to the connection between the fastening section 113 and the coupling section 111 adopt smooth transition, or the inner wall surface adopts smooth transition, or the outer wall surface adopts rounded transition.

[0067] Exemplarily, a rounded structure is formed at one end of the coupling section 111 away from the fastening section 113 .

[0068] In some examples, since the wall surface of the coupling section 111 needs to contact the skin, a certain friction force will be generated. The rounded structure formed makes the wall thickness of the coupling section 111 more uniform, thereby avoiding excessive force changes during the movement of the coupling section 111, resulting in relative displacement of the coupling sleeve 1 and the ultrasound probe.

[0069] Exemplarily, a transition section 112 is formed between the fastening section 113 and the coupling section 111 , the transition section 112 is smoothly connected to the fastening section 113 and the coupling section 111 , and the wall thickness of the transition section 112 is uniformly set.

[0070] In some examples, the transition section 112 forms a rounded corner structure with the wall surface of the coupling sleeve 1, that is, the two connections of the outer wall surface of the transition section 112 form rounded corners. Or in some examples, the transition section 112 forms a rounded corner structure with the wall surface of the accommodating groove 11, that is, the two connections of the inner wall surface of the transition section 112 form rounded corners. Or in some examples, the wall surface connections of the transition section 112 all form rounded corner structures, that is, the connections between the inner wall surface and the outer wall surface of the transition section 112 all form rounded corners. As a result, the connection between the fastening section 113 and the coupling section 111 is smoother through the transition section 112. At the same time, the wall thickness of the transition section 112 is uniform, which can produce the same deformation, avoiding the phenomenon that the thinner wall thickness of the transition section 112 cracks first.

[0071] Exemplarily, the coupling sleeve 1 further includes a flange 12 . The flange 12 is disposed on the fastening section 113 , and the fastening assembly 2 is detachably sleeved on a portion of the fastening section 113 between the flange 12 and the coupling section 111 .

[0072] In some examples, such as Figure 3 As shown, the flange 12 may correspond to one end of the coupling sleeve 1 where the receiving groove 11 is provided with an opening, or in some examples, the flange 12 corresponds to between the opening and the bottom of the receiving groove 11 and corresponds to the fastening section 113 .

[0073] Exemplarily, the fastening section 113 is a columnar structure, the transition section 112 is a table-like structure, the coupling section 111 is a columnar structure, and the cross-sectional area of ​​the fastening section 113 is greater than the cross-sectional area of ​​the coupling section 111 .

[0074] In some examples, the fastening section 113 is block-shaped, and the coupling section 111 is block-shaped. Since there is a difference between the cross-sectional areas of the two connecting parts of the transition section 112, the sizes of the two ends of the transition section 112 are different, so that the transition section 112 has an inclined side wall, and thus the transition section 112 is in the shape of a prism.
