Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, it relates to an ultrasonic puncture auxiliary device and ultrasonic puncture system. BACKGROUND

[0002] Upper limb puncture refers to inserting a needle or catheter into a blood vessel in the upper limb (such as arm, forearm, back of hand, etc.) through the skin for medical procedures. This process is mainly used for venous or arterial puncture, commonly seen in medical scenarios such as infusion, blood drawing, drug injection, catheter placement, etc. Since the arm veins may be thin or hidden deep, accurate puncture requires high skill.

[0003] Upper limb ultrasonic puncture is a technique that uses ultrasonic equipment for real-time imaging to assist blood vessel puncture, commonly used for venous and arterial puncture. In ultrasonic upper limb puncture, the doctor first locates the target blood vessel with an ultrasonic probe, then determines the puncture point, and finally completes the ultrasonic-guided needle insertion and adjustment for post-puncture observation and treatment. Ultrasonic guidance improves the accuracy of puncture by displaying the depth, direction and blood flow state of the blood vessel, and is particularly suitable for patients with difficult-to-touch blood vessels, such as those with poor venous condition, obesity or long-term infusion. Compared with traditional methods, ultrasonic puncture reduces the risk of puncture failure and complications, and improves patient comfort and medical efficiency.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0052] The following is combined Figures 1 to 6 The ultrasonic puncture auxiliary device and ultrasonic puncture system provided in this utility model will be described in detail through specific embodiments and application scenarios.

[0053] Firstly, such as Figure 1 As shown, this embodiment provides an ultrasonic puncture assist device 1, including: a mounting frame 11, an adjustment component 12, a locking component 13, and a puncture guide component 14.

[0054] The adjustment assembly 12 is used to mount the ultrasonic probe 2. The adjustment assembly 12 is vertically mounted on the mounting frame 11 and can rotate within the ultrasonic plane formed by the ultrasonic probe 2 and tilt outside the ultrasonic plane to adjust the position of the ultrasonic probe 2.

[0055] The locking component 13 is located on the adjustment component 12, and the locking component 13 is used to lock the position of the ultrasound probe 2 after it has been adjusted to a suitable position.

[0056] The puncture guide assembly 14 is located on the adjustment assembly 12 and is used to accommodate the puncture needle.

[0057] Understandably, ultrasound probe 2 can emit an ultrasound beam. During the puncture, the ultrasound can detect blood vessels, and ultrasound probe 2 can also receive reflected ultrasound waves to generate images. The ultrasound plane usually refers to the area covered by the sound waves formed when ultrasound probe 2 emits ultrasound waves. This area can be used to capture information about the internal structure of blood vessels. Generally, "inside the ultrasound plane" refers to the plane where the ultrasound beam is located, and the ultrasound plane is parallel to the imaging plane; "outside the ultrasound plane" refers to the non-parallelism of the imaging plane caused by the movement of ultrasound probe 2, including rotation around the center line of ultrasound probe 2 and tilting movements to adjust the tilt angle of ultrasound probe 2.

[0058] The mounting bracket 11 provides a mounting support for the adjustment component 12 and provides support for the puncture site for the patient. When the mounting bracket 11 is set to a smaller size, ultrasonic puncture can be performed on the patient's upper limb. This embodiment uses the upper limb as the puncture site for illustration.

[0059] The adjusting assembly 12 is used to support and accommodate the ultrasound probe 2, and the lifting movement of the adjusting assembly 12 relative to the mounting frame 11 can adjust the distance of the ultrasound probe 2 relative to the upper limb of the patient, so as to adapt to the upper limbs of different thicknesses, so as to ensure that the distance of the ultrasound probe 2 to the outer surface of the upper limb is equal.

[0060] Further, the adjusting assembly 12 can also adjust the tilting movement of the ultrasound probe 2 out of the ultrasound plane and the rotation in the ultrasound plane, and by adjusting the ultrasound probe 2 in the ultrasound plane and out of the ultrasound plane, the pose of the ultrasound probe 2 can be adjusted, the target blood vessel can be quickly positioned, and the puncture point can be determined.

[0061] Specifically, the adjusting assembly 12 can be provided with a rotating shaft 143 to rotate around the mounting frame 11 to realize the rotation in the ultrasound plane, or a gear can be provided to rotate to realize the rotation in the ultrasound plane, or a telescopic rod or a guide rail slider can be provided to realize the tilting movement out of the ultrasound plane.

[0062] After the adjusting assembly 12 has completed the adjustment of the pose of the ultrasound probe 2, the ultrasound probe 2 has completed the detection of the needle insertion point, the needle insertion angle and the needle insertion depth of the blood vessel, and the pose of the ultrasound probe 2 is locked by using the locking assembly 13. In this way, the plane of the ultrasound probe 2 emitting the ultrasound waves is fixed, and the target blood vessel can also obtain clear imaging. The user's operation on the pose of the ultrasound probe 2 has ended, and the locking assembly 13 can ensure that the pose of the ultrasound probe 2 is fixed and unchanged during the subsequent puncture operation, and the user does not need to hold the ultrasound probe 2, which frees the user's hand movement, so that the user can hold the puncture needle with both hands.

[0063] Specifically, the locking assembly 13 can use a fastener to fix the pose of the adjusting assembly 12, or can use a latch to fix the pose of the adjusting assembly 12, or can use a buckle to fix the pose of the adjusting assembly 12.

[0064] Correspondingly, the puncture guide assembly 14 is used to provide guidance for the puncture path of the puncture needle, and since the puncture guide assembly 14 is arranged on the adjusting assembly 12, the puncture guide assembly 14 can be adjusted along with the change of the pose of the ultrasound probe 2 along with the adjustment of the adjusting assembly 12, so that the puncture path of the puncture needle can be adapted to the adjustment of the pose of the ultrasound probe 2, so as to ensure that the puncture path of the puncture needle is adapted to the ultrasound beam emitted by the ultrasound probe 2, so that the puncture needle can puncture the blood vessel at the needle insertion point, the needle insertion angle and the needle insertion depth determined by the ultrasound probe 2, and the accuracy and safety of the puncture are improved.

[0065] In practical application, first, the upper limbs of the patient are placed on the mounting frame 11, then the ultrasonic probe 2 is installed on the adjusting assembly 12, the height of the ultrasonic probe 2 is adjusted through the adjusting assembly 12, the angle of ultrasonic wave emitted by the ultrasonic probe 2 is adjusted, the adjustment of the position and posture of the ultrasonic probe 2 is realized, then the position and posture of the ultrasonic probe 2 is locked by using the locking assembly 13, finally, the puncture needle is placed in the puncture guiding assembly 14, and the puncture operation is performed under the guidance of the puncture guiding assembly 14.

[0066] The ultrasonic puncture auxiliary device 1 provided by the utility model, through the adjusting assembly 12, the height adjustment of the ultrasonic probe 2 relative to the mounting frame 11 is adjusted, the rotary adjustment of the ultrasonic probe 2 in the ultrasonic plane and the tilting movement of the ultrasonic probe 2 out of the ultrasonic plane are realized, the adjustment of the position and posture of the ultrasonic probe 2 is realized, the ultrasonic probe 2 adjusted to the appropriate position and posture is locked by using the locking assembly 13, so that the user does not need to hold the ultrasonic probe 2 when puncturing, and the guiding effect of the puncture needle is completed through the puncture guiding assembly 14, so that the puncture needle can puncture the blood vessel at the determined needle insertion point, at the determined needle insertion angle and the determined needle insertion depth, the adjustment of the position and posture of the ultrasonic probe 2 is separated from the puncture operation, the convenience of ultrasonic puncture is improved, and the difficulty of ultrasonic puncture is reduced.

[0067] In some embodiments, as shown in Figs. Figure 2 and Figure 3 The adjusting assembly 12 of the embodiment comprises a lifting plate 121.

[0068] The mounting frame 11 comprises a top plate 111, a bottom plate 112 and a support 113.

[0069] The top plate 111 and the bottom plate 112 are respectively arranged at two ends of the support 113.

[0070] The lifting plate 121 is arranged between the top plate 111 and the bottom plate 112, and the lifting plate 121 is installed on the support 113 in a lifting manner.

[0071] It can be understood that the lifting adjustment of the lifting plate 121 is realized based on the movement of the lifting plate 121 relative to the support 113. When the upper limbs are placed on the bottom plate 112, the user can manually adjust the height of the lifting plate 121 according to the thickness of the upper limbs, so as to adjust the distance between the ultrasonic probe 2 and the upper limbs. The structure is simple and can be realized manually, thereby reducing the adjustment cost.

[0072] Further, the support 113 can be a support rod, mounting holes 14121 are arranged on the top plate 111, the bottom plate 112 and the lifting plate 121, the top plate 111 and the bottom plate 112 are fixedly sleeved on the support rod, the lifting plate 121 is sleeved on the support rod in a lifting manner, and the lifting adjustment of the lifting plate 121 is realized through the movement of the lifting plate 121 on the support rod.

[0073] In some embodiments, as shown in Figure 3 The adjusting assembly 12 of the embodiment further comprises a first support 122 and a second support 123.

[0074] The first support 122 is rotatably arranged on the lifting plate 121, the second support 123 is rotatably arranged on the first support 122, and the ultrasonic probe 2 is mounted on the second support 123.

[0075] The rotation axis of the first support 122 and the rotation axis of the second support 123 are arranged vertically.

[0076] It can be understood that the first support 122 can rotate relative to the lifting plate 121, the second support 123 can rotate relative to the first support 122, and the rotation axis of the first support 122 and the rotation axis of the second support 123 are arranged vertically, so that the rotation directions of the first support 122 and the second support 123 are perpendicular to each other.

[0077] In actual application, the first support 122 rotates in the ultrasonic plane, and the second support 123 tilts out of the ultrasonic plane, or the second support 123 rotates in the ultrasonic plane, and the first support 122 tilts out of the ultrasonic plane.

[0078] The embodiment sets the first support 122 and the second support 123 on the adjusting assembly 12, and the rotation directions of the first support 122 and the second support 123 are perpendicular to each other, so that the rotation of the first support 122 relative to the lifting plate 121 and the rotation of the second support 123 relative to the first support 122 can realize that the adjusting assembly 12 can rotate in the ultrasonic plane formed by the ultrasonic probe 2 and tilt out of the ultrasonic plane, and the position and posture of the ultrasonic probe 2 can be conveniently adjusted. The rotation structure design of the first support 122 and the second support 123 is compact and simple in adjustment mode, and easy to operate.

[0079] In some embodiments, as shown in Figure 3 The adjusting assembly 12 of the embodiment further comprises a first bearing 124 and a first rotary joint 125.

[0080] The first support 122 is rotatably connected to the lifting plate 121 through the first rotary joint 125, and the first end of the first rotary joint 125 is provided with the first bearing 124.

[0081] It can be understood that the first rotary joint 125 can realize rotation around a fixed shaft, has simple structure, occupies small space, and has flexible movement, and can reliably realize the rotation connection of the first support 122 and the lifting plate 121.

[0082] Further, the first bearing 124 can provide support for the first rotary joint 125, reduce friction, increase the service life of the first rotary joint 125, and reduce the need for maintenance and replacement of the first rotary joint 125.

[0083] In some embodiments, as shown in Figure 3 and Figure 4 The adjusting assembly 12 of the embodiment further includes a second bearing 126 and a second rotary joint 127.

[0084] The second support 123 is rotatably connected with the first support 122 through the second rotary joint 127, and the first end of the second rotary joint 127 is provided with the second bearing 126.

[0085] It can be understood that the second rotary joint 127 can realize rotation around a fixed shaft, has simple structure, occupies small space, and has flexible movement, and can reliably realize the rotation connection of the first support 122 and the second support 123.

[0086] Further, the second bearing 126 can provide support for the second rotary joint 127, reduce friction, increase the service life of the second rotary joint 127, and reduce the need for maintenance and replacement of the second rotary joint 127.

[0087] In some embodiments, as shown in Figure 3 The locking assembly 13 of the embodiment includes a first damping ring 131.

[0088] The second end of the first rotary joint 125 is provided with the first damping ring 131.

[0089] It can be understood that after the rotation angle of the first support 122 is adjusted, the pose of the ultrasonic probe 2 needs to be locked by using the locking assembly 13, and the first damping ring 131 can generate damping energy consumption through friction between the first damping ring 131 and the first rotary joint 125, so as to inhibit the rotary motion of the first rotary joint 125, and thus the rotation of the first support 122 is locked without manual operation of the first support 122.

[0090] Since the first damping ring 131 occupies small space and can be directly sleeved on the first rotary joint 125, no additional installation space is needed, space is saved, and the first damping ring 131 is light in weight and easy to install, thereby conveniently realizing the locking of the first support 122.

[0091] In some embodiments, as shown in Figure 4 The locking assembly 13 of the embodiment includes a second damping ring 132.

[0092] The second end of the second rotary joint 127 is provided with the second damping ring 132.

[0093] It can be understood that after the rotation angle of the second support 123 is adjusted, the pose of the ultrasonic probe 2 needs to be locked using the locking assembly 13, and the second damping ring 132 can generate damping energy consumption through friction between the second damping ring 132 and the second rotary joint 127 to inhibit the rotary motion of the second rotary joint 127, and thus the rotation of the second support 123 is locked without manually operating the second support 123.

[0094] Since the second damping ring 132 occupies a small space and can be directly sleeved on the second rotary joint 127 without the need for additional installation space, space is saved, and the second damping ring 132 is light in weight and easy to install, thereby conveniently achieving locking of the second support 123.

[0095] In some embodiments, as shown in Figure 3 the lifting plate 121 of the present embodiment is hollow, the first support 122 and the second support 123 are both elliptical supports, and the ultrasonic probe 2 is placed at the center of the second support 123.

[0096] It can be understood that the lifting plate 121 of the present embodiment is hollow, a containing space is formed at the center, the first support 122 and the second support 123 are installed in the containing space, and installation space is saved, so that the overall volume of the adjusting assembly 12 is small.

[0097] Furthermore, the first support 122 and the second support 123 are elliptical supports that can rotate in two directions, and the ultrasonic probe 2 is placed at the center of the second support 123, so that the ultrasonic probe 2 is placed at the centers of the two elliptical supports, the first support 122 and the second support 123 are symmetrically arranged relative to the ultrasonic probe 2, the distance from the center of the elliptical support to the edge of the elliptical support is constant, so that when the first support 122 and the second support 123 rotate, the ultrasonic probe 2 can scan at a uniform distance during rotation, providing consistent image quality, and the pose adjustment of the ultrasonic probe 2 is always at the center of the symmetric space, which can ensure that the target area is scanned comprehensively and uniformly, reducing imaging dead angles.

[0098] In some embodiments, as shown in Figure 5 and Figure 6 the puncture guide assembly 14 of the present embodiment includes a mounting seat 141 and a catheter 142.

[0099] The mounting seat 141 is provided on the adjusting assembly 12, and the catheter 142 is rotatably provided on the mounting seat 141.

[0100] The rotation direction of the catheter 142 is in the ultrasonic plane.

[0101] It can be understood that the mounting seat 141 is provided on the adjusting assembly 12, and the position of the mounting seat 141 can be changed as the adjusting assembly 12 is adjusted.

[0102] The catheter 142 can rotate in the ultrasound plane, that is, the catheter 142 can guide the puncture needle to adjust the puncture angle in the ultrasound plane, the user can more clearly observe the position and movement of the puncture needle, and the accuracy and safety of puncture are improved. The catheter 142 can rotate in the ultrasound plane, the angle of needle insertion can be adjusted, and the depth of needle insertion is further increased, which further increases the adjustment flexibility of the puncture needle and ensures that the puncture needle accurately reaches the target needle insertion site.

[0103] In some examples, the mounting seat 141 is fixedly connected to the second bracket 123, and since the second bracket 123 can rotate in the ultrasound plane, the mounting seat 141 can also rotate in the ultrasound plane, thereby ensuring that the catheter 142 rotates in the ultrasound plane.

[0104] In some embodiments, as shown in Figure 6 The mounting seat 141 of the present embodiment includes a connecting portion 1411 and a mounting portion 1412.

[0105] One end of the connecting portion 1411 is connected to the adjusting assembly 12, and the other end of the connecting portion 1411 is connected to the mounting portion 1412.

[0106] The mounting portion 1412 is provided with a mounting hole 14121, the catheter 142 passes through the mounting hole 14121, the side wall of the catheter 142 is fixedly connected with a rotating shaft 143, and the other end of the rotating shaft 143 is rotatably arranged in the mounting portion 1412.

[0107] It can be understood that the catheter 142 can rotate along the axis of the rotating shaft 143 in the mounting hole 14121, and the catheter 142 is arranged in the mounting hole 14121 of the mounting portion 1412, which is relatively compact, and the rotation of the catheter 142 is realized in the mounting portion 1412. The two sides of the mounting portion 1412 can also limit the rotation of the catheter 142, so that the catheter 142 cannot rotate continuously by 360°, and the rotation amplitude of the puncture needle is avoided to be too large and difficult to control accurately.

[0108] In some embodiments, as shown in Figure 6 The connecting portion 1411 and the mounting portion 1412 of the present embodiment are arranged at an angle, and the mounting portion 1412 is inclinedly arranged towards the direction close to the ultrasound probe 2.

[0109] It can be understood that since the connecting portion 1411 and the mounting portion 1412 are arranged at an angle, the mounting portion 1412 is inclined towards the direction of the ultrasound probe 2, so that the puncture needle is closer to the ultrasound probe 2, and the puncture needle in the ultrasound plane is more clear, and the accuracy of puncture is further improved.

[0110] In the second aspect, in some embodiments, the present embodiment provides an ultrasonic puncture system, comprising: an ultrasonic probe 2, a puncture needle, an imaging device and an auxiliary device 1 as above.

[0111] The ultrasonic probe 2 and the puncture needle are mounted on the auxiliary device 1, and the ultrasonic probe 2 is in communication connection with the imaging device.

[0112] Specifically, since the ultrasonic puncture system comprises the auxiliary device 1, the specific structure of the auxiliary device 1 is referred to the above-mentioned embodiments, the ultrasonic puncture system shown in the present embodiment comprises all the technical solutions of the above-mentioned embodiments, therefore, at least has all the beneficial effects obtained by all the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0113] It can be understood that the auxiliary device 1 is used for accommodating the ultrasonic probe 2 and the puncture needle, and can also adjust and fix the pose of the ultrasonic probe 2, and guide the puncture needle to perform puncture operation.

[0114] The ultrasonic probe 2 can exchange images and data information with the imaging device, the ultrasonic probe 2 feeds back the images of the internal tissues obtained to the imaging device, and displays the images using the imaging device, and the imaging device can display the depth, direction and blood flow state of the blood vessels, so that the user can perform accurate puncture operation under monitoring, avoid damage to the surrounding tissues, and improve the safety and effectiveness of puncture.

[0115] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
