Description

Technical Field

[0001] The present invention relates to the field of ultrasonic puncture-assisted technology, and in particular to an ultrasonic intervention-assisted operation device. Background Art

[0002] Ultrasound intervention is an extension and development of the clinical application of ultrasound. It mainly performs puncture operations under the dynamic monitoring or guidance of real-time ultrasound. During the entire operation, the puncture needle is indispensable. In the interventional surgery guided by medical imaging, the "one-step method" and "two-step method" of ultrasound access refer to different technical processes for puncture under ultrasound guidance. The "one-step method" of ultrasound access is more frequently used because it is simple and fast to operate and does not require additional steps.

[0003] The "one-step method" operation requires the puncture needle and the ultrasound probe to maintain a specific angle, and both hands are required to cooperate with the handheld device. When performing delicate operations for a long time, the operator's arms, fingers, wrists and other parts need to maintain a state continuously. During the operation, there is a lack of body support and operation assistance to reduce the operating pressure, making it difficult for the operator to interrupt the current operating state. The long-term use of fingers, wrists and other parts may affect the delicate operation, and the angles of the puncture needle and ultrasound probe need to be adjusted frequently to ensure the accuracy of the puncture trajectory.

[0004] At present, auxiliary equipment for the "one-step method" operation includes an ultrasonic puncture auxiliary guide, which is installed on the ultrasonic probe and serves as a probe holder to assist users in reducing operating actions. However, the puncture needle is installed on the probe holder. Although the matching angle of the puncture needle and the ultrasonic probe can be guaranteed, the adjustment angle of the puncture needle on the ultrasonic probe holder is limited. When the two are combined together, it is difficult to obtain clear operating feedback during the puncture operation. It also lacks a certain degree of flexible operation, and the weight of the entire arm cannot be supported, and it cannot provide the operator with much gain auxiliary effect.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-2 , an ultrasonic interventional auxiliary operation device, comprising a mounting seat 1 and a joint rod 4, the mounting seat 1 is provided with a mounting strap 2 and an elastic strap 3, the elastic strap 3 is provided with a plurality of connecting buckles 24, the mounting strap 2 is installed on the arm for wearing the device, the elastic strap 3 is sleeved on the neck or other positions that can provide support, so that the device can use the body as a support point and let other parts of the body as a supporting part, and at the same time, it is installed to the joint rod 4 or other positions through the connecting buckle 24 to form three supporting points. When installed to the joint rod 4, a triangular supporting structure can be formed with the sleeve points of the mounting seat 1, the joint rod 4 and the elastic strap 3, while ensuring the support stability, the distance and length between each supporting point of the elastic strap 3 can be adjusted to provide effective support force for the user's arm for operation, so as to assist the continuous operation;

[0039] Reference Figure 1-2In this embodiment, the mounting base 1 can also be installed on any fixed support device such as a cylindrical support rod, a support frame with a tripod structure, a guardrail on the edge of a hospital bed, etc. After installation, the way of installation on the arm can be changed. At the same time, because there is a fixed support point, the mounting strap 2 and the elastic strap 3 can still be installed on the operator's body or other positions to form a three-point fixation to provide operation support.

[0040] In an example scenario: the mounting base 1 is installed on the mobile drip stand (cylindrical support rod) by bolts, mounting straps 2, tapes, nylon buckles or any other suitable fixing methods. After the mounting base 1 is fixed, the fixed point serves as a support point for the user. The elastic strap 3 is installed on the mobile drip stand (cylindrical support rod) in the same way and is located above the fixed point. One or more ends of the elastic strap 3 are installed on the joint rod 4 by connecting the buckle 24 to increase multiple fixed support points at different positions, forming a support rod structure for pulling the joint rod 4. When the user operates, the position of the joint rod 4 is supported, thereby enhancing the support force for the user's operation. When no operation is performed, the device uses the formed support structure to be fixed or suspended on the mobile drip stand (cylindrical support rod) for the next operation.

[0041] In another example scenario, the difference compared to the above example scenario is that the mounting base 1 is fixed on the guardrail at the edge of the bed, and the elastic strap 3 is installed at the human body position (neck), so that the user can help operate according to the movement of his body (lowering the head, raising the head, etc.).

[0042] Reference Figure 1-6 A joint shaft is provided in the middle position of the joint rod 4, which is used to divide the joint rod 4 into an active rod body 1 5 and an active rod body 2 6. A sliding groove 7 is provided on the active rod body 1 5. The active rod 2 is connected to the mounting seat 1 through a rotating rod. Through the rotating rod and the joint shaft, after the patient wears the device, the horizontal degree of freedom and the longitudinal degree of freedom can be rotated respectively, so that the device can be used for multi-degree-of-freedom rotation, thereby adapting to the bending movement of the arm to assist the smooth operation of ultrasonic intervention.

[0043] An auxiliary frame 8 is provided at one end of the joint rod 4 away from the mounting seat 1. The auxiliary frame 8 is used to clamp the puncture needle. At the same time, a non-handheld auxiliary operation mode is provided for the user. The user operates the puncture needle through the auxiliary frame 8, which reduces the unstable influence of the puncture needle insertion trajectory, angle and positioning operation caused by the long-term grip of the puncture needle by the hand or fingers;

[0044] The auxiliary frame 8 is connected to the joint rod 4 through a rotating slider 9, and the rotating slider 9 slides inside the sliding groove 7. In a specific implementation, the rotating slider 9 moves in the sliding groove 7 through an I-shaped slider, and there is damping in the sliding contact, which is used for the rotating slider 9 to slide in the sliding process. In the case of no external force, after the rotating slider 9 slides and adjusts, it will not be displaced by gravity and other factors, and can generate resistance when sliding in one direction or in a reciprocating direction. The user needs to use a little more force than usual to operate, thereby reducing the shaking that may be caused by muscle spasms or unstable grip of the device;

[0045] An operation slot 10 is provided inside the auxiliary frame 8. A guide matching structure 13 for fixing and guiding the advancing route of the puncture needle is provided on the auxiliary frame 8. The operation slot 10 is used for the user to insert his hand into it and use the auxiliary frame 8 to assist the operation performed by the hand;

[0046] Reference Figure 1-6 The auxiliary frame 8 rotates with the rotating slider 9 as the axis. By rotating the slider 9, the auxiliary frame 8 can drive the puncture needle to adjust the angle. When the one-step method is used for ultrasonic intervention, the angle of the puncture needle can be adjusted in multiple positions to cooperate with the ultrasonic guidance probe for detection, so as to reach the biopsy position more smoothly. In the process of fixing the puncture needle, the auxiliary frame 8 can also adjust the angle of the puncture needle on the auxiliary frame 8 to assist the user to flexibly adjust and change the puncture trajectory during use;

[0047] In the specific implementation, the auxiliary frame 8 has damping when rotating and sliding the sliding block 9, and the damping is used to prevent the customer from making changes to the components after adjusting the components due to non-human factors such as gravity, so as to prevent the components from being too active and affecting the inconvenience of operation;

[0048] A support hose 18 is provided at the bottom end of the joint rod 4. The support hose 18 is used to provide a support point for the end of the joint rod 4. The support point includes but is not limited to the patient's body part, a bed or other supporting platform. In this embodiment, the support point is preferably selected on the patient's body part to assist the ultrasound guidance probe to locate the position of ultrasound intervention. Figure 1-6 In a specific embodiment of the present application, an auxiliary groove 11 is provided on one side wall of the auxiliary frame 8. The auxiliary groove 11 is a T-shaped structure connected to the operation groove 10. A positioning frame 12 matching the auxiliary groove 11 is provided inside the auxiliary groove 11. The positioning frame 12 is a rectangular structure. The positioning frame 12 moves in the auxiliary groove 11 by sliding a slider in the auxiliary groove 11, so that the user can move the puncture needle along a stable trajectory after fixing the puncture needle through the positioning frame 12, thereby assisting the stability of the intervention operation trajectory;

[0049] The guiding matching structure 13 is installed on the positioning frame 12, and the guiding matching structure 13 is used to fix the puncture needle and assist the patient to operate accurately on the puncture needle so that the puncture needle can feedback according to the user's expected idea;

[0050] Reference Figure 1-6 In a specific embodiment of the present application, the guide matching structure 13 includes an operating shaft 131 located in the middle of the positioning frame 12, one end of the operating shaft 131 extends into the operating slot 10, and the end surface of the other end is flush with the surface of the positioning frame 12. After the operating shaft 131 extends into the operating slot 10, the user can directly control the rotation of the operating shaft 131. After the operating shaft 131 matches with the penetration needle, the user can use the operating shaft 131 as the axis to adjust the angle of the penetration needle.

[0051] A fixing plate 132 is symmetrically provided on the operating shaft 131. The length of the fixing plate 132 is greater than that of the operating shaft 131. A reset feedback spring 133 is provided between the fixing plate 132 and the operating shaft 131. The fixing plate 132 and the operating shaft 131 are combined to form a cylindrical structure. The part of the fixing plate 132 that exceeds the operating shaft 131 serves as a structure for clamping and fixing the measuring needle, and the clamping force is ensured by the reset feedback spring 133.

[0052] An operating ring 134 is provided at one end of the operating shaft 131 extending to the operating slot 10. A pressing protrusion 135 connected to the fixing plate 132 is provided inside the operating ring 134. A feedback grid is provided between the operating shaft 131 and the positioning frame 12 for feedback adjustment of touch. The operating ring 134 is an annular structure for the user to insert a finger. When assisting the user in performing the puncture operation, it provides support for precise operation. When the user adjusts the angle through the operating shaft 131, each rotation of the feedback grid will provide vibration feedback, so that the user can get clear operation feedback. After adjusting the angle and performing the puncture, if the subcutaneous tissue moves, the patient's body shakes, or other factors cause the puncture needle to produce changes outside the predetermined angle, vibration feedback will also be obtained, so that the user can clearly perceive the changes, thereby assisting the user in the puncture operation;

[0053] Reference Figure 1-6In the specific embodiment of the present application, a locking frame 14 is provided at one end of the fixing plate 132 extending out of the auxiliary frame 8. The locking frame 14 is sleeved on the fixing plate 132 and connected to the fixing plate 132 through a sliding ball 15. The locking frame 14 can replace the structural fixation of the fixing plate 132 to fix puncture needles of different sizes. The clamping force and the clamping gap are ensured by the reset feedback spring 133 to ensure that the two locking frames 14 or the fixing plate 132 can stably clamp the puncture needle, thereby increasing the adaptation range of the puncture needle. In addition, the sliding ball 15 can make the locking frame 14 slide within the range formed by the cooperation with the fixing plate 132, thereby driving the puncture needle to perform additional movement. In the specific implementation, the locking frame 14 has damping through the movement of the sliding ball 15, and the damping is set to meet the damping force of the puncture needle to normally penetrate the skin tissue;

[0054] A punch structure 16 is provided at one end of the positioning frame 12, and the punch structure 16 is used to push the locking frame 14 to move the locking frame 14 along the puncture trajectory. The punch structure 16 allows the locking frame 14 to drive the puncture needle to accelerate and move a certain distance, and the maximum distance is limited by the matching stroke of the locking frame 14 and the fixing plate 132.

[0055] The top punch structure 16 includes a spring top punch frame 161, a top punch protrusion 162 is provided inside the spring top punch frame 161, a spring buckle 163 is provided at the bottom of the top punch protrusion 162, and a top punch spring 164 is provided between the top punch structure 16 and the spring top punch frame 161. It is not difficult to see from the above design that the top punch spring 164 is initially in a compressed state, and the compressed state of the top punch spring 164 is fixed by the spring buckle 163. By releasing the restriction of the spring buckle 163 on the top punch spring 164 (it can be pressed in the operating groove to release the spring buckle 163 after contraction), the top punch spring 164 will extend out quickly, causing the top punch protrusion 162 to extend out together, and the top punch protrusion 162 will quickly impact the locking frame 14, causing the locking frame 14 to drive the clamped and fixed puncture needle to move. Because it has a certain acceleration, the puncture needle can move forward a certain distance quickly and smoothly, assisting the user in performing ultrasonic intervention operations, and ensuring the stability and accuracy of the insertion point, the initial insertion trajectory and the insertion angle.

[0056] Reference Figure 1-6 In a specific embodiment of the present application, a guide plate 17 is provided on one side of the auxiliary groove 11, and a plurality of guide frames 25 are provided on the guide plate 17. The guide frames 25 are used to guide the advancement trajectory of the puncture needle tube. The guide frames 25 are plugged into the guide plate 17 to perform secondary positioning on the puncture needle, thereby preventing the puncture needle from shaking or becoming unstable during the advancement process due to the excessive length of the needle body, thereby enhancing the stability of the operation, and ensuring that the non-interventional operation can be performed according to the predetermined trajectory and accurately reach the expected position.

[0057] In a specific embodiment of the present application, an auxiliary strip 19 is symmetrically provided at the bottom end of the support hose 18, and the auxiliary strip 19 is connected to the support hose 18 through an auxiliary rod 20, and the auxiliary rod 20 is an arc-shaped rod. The support hose 18 can use the patient's body part as a support point through the auxiliary strip 19. Because the auxiliary strip 19 is a strip structure and is symmetrically distributed, the position where the ultrasonic intervention operation is to be performed can be marked and fixed through the auxiliary strip 19, so as to assist the user in locating the skin area for the operation;

[0058] In addition, the support hose 18 can provide a larger support area through the auxiliary strip 19, and because of the arc-shaped structure of the auxiliary rod 20, when the user wears the device on the arm for operation, the arm can be transferred partly to the support hose 18, which makes the user more labor-saving while the operating position will not change, and can help fix the patient's body to prevent the patient from creeping, shaking or spasming.

[0059] In a specific embodiment of the present application, a scale rod 21 is sleeved on the rotating slider 9, and the end of the scale rod 21 is a spherical structure. The end of the scale rod 21 away from the rotating slider 9 is provided with a scale ring 22 connected to the auxiliary frame 8, and the scale ring 22 is provided with a plurality of grooves 23 that match the scale rod 21. It is not difficult to see from the above design that the grooves 23 are grooves 23 of a semicircular structure and are distributed in a circle around the scale rod 21. When the spherical end of the scale rod 21 enters a groove 23, it means that the auxiliary frame 8 has rotated to a specific angle, which provides an auxiliary judgment for the next puncture operation. In addition, when the spherical end of the scale rod 21 enters from one groove 23 to the next groove 23, it will provide an obvious vibration feedback to the user, and the user can know the current puncture angle without observing it. Without artificially applying too much force, after the spherical end of the scale rod 21 enters the groove 23, it can prevent the auxiliary frame 8 from continuing to rotate, so as to assist in supporting the user's operation to disengage. The user can stop or disengage from the operation for a certain period of time, and then return to the operating point to continue the operation.

[0060] The above description 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
