Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ultrasound positioning device for intraoperative interventional occlusion of atrial septal defect associated with pulmonary hypertension. Background Art

[0002] Small atrial septal defects usually close on their own, but larger ones cannot, leading to overload of the right atrium and right ventricle, and eventually causing pulmonary hypertension. Interventional occlusion uses a femoral vein puncture method to deliver the occluding umbrella into the atrium, fix it to the atrial septal defect (ASD), and permanently stay at the defect site to restore normal blood circulation. During the operation, ultrasound assistance is required. Ultrasound is divided into two situations: in vivo and in vitro. In the in vitro situation, an ordinary ultrasound handle is used, and the surgeon is required to adjust the position and angle of the ultrasound handle to achieve the best image. In the subsequent operation process, the surgeon is assisted in performing the operation. In this process, the surgeon is required to continuously control the position of the ultrasound handle, occupying one hand of the surgeon and causing difficulties in the operation.

[0003] In view of the above problems, an ultrasound positioning device for interventional occlusion of atrial septal defect with pulmonary hypertension is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide an ultrasound positioning device during interventional occlusion of atrial septal defect with pulmonary hypertension, which solves the problem in the background technology that the doctor needs to continuously use one hand to control the ultrasound handle, thereby increasing the difficulty of the operation.

The interior of the positioning groove is rotatably connected to the transverse screw through the transverse motor, the outer wall of the transverse screw is threadedly connected to the transverse screw block, the interior of the positioning groove is fixedly connected to the auxiliary block, and the interior of the positioning groove is provided with a longitudinal adjustment mechanism between the transverse screw block and the auxiliary block.

The three-dimensional movement of the ultrasonic handle 7 can be achieved through the lateral adjustment mechanism 3, the longitudinal adjustment mechanism 4 and the telescopic rod 6, so as to contact with the patient for detection, and it is installed on the bed through the bracket 9 for easy use.

[0019] Combination Figure 2 and Figure 3The lateral adjustment mechanism 3 includes a lateral motor 301, a lateral screw 302, a lateral screw block 303 and an auxiliary block 304. The interior of the positioning groove 2 is rotatably connected to the lateral screw 302 through the lateral motor 301. The outer wall of the lateral screw 302 is threadedly connected to the lateral screw block 303. The interior of the positioning groove 2 is fixedly connected to the auxiliary block 304. The interior of the positioning groove 2 is located between the lateral screw block 303 and the auxiliary block 304. The longitudinal adjustment mechanism 4 includes a longitudinal motor 401, a longitudinal screw 402 and a longitudinal screw block 403. The interior of the lateral screw block 303 is fixedly connected to the longitudinal motor 401. The output shaft of the longitudinal motor 401 is fixedly connected to the longitudinal screw 402. The outer wall of the auxiliary block 304 is threadedly connected to the lateral screw block 303. The wall is slidably connected with a longitudinal adapter block 404, the longitudinal screw 402 is rotatably connected to the longitudinal adapter block 404, the outer wall of the longitudinal screw 402 is threadedly connected with a longitudinal screw block 403, and a limiting rod 10 is fixedly connected between the transverse screw block 303 and the longitudinal adapter block 404, and the limiting rod 10 passes through the longitudinal screw block 403; the transverse motor 301 drives the transverse screw 302 to rotate, so that the transverse screw block 303 moves laterally, driving the longitudinal screw 402 and the longitudinal adapter block 404 to move, and then the longitudinal motor 401 drives the longitudinal screw 402 to rotate. Due to the limiting rod 10, the longitudinal screw block 403 can move longitudinally, and the contact box 501 is driven up and down by the telescopic rod 6 to allow the ultrasonic handle 7 to contact the patient.

[0020] Combination Figure 3 and Figure 4 The contact adjustment mechanism 5 includes a contact box 501, a splint 502, a rotating rod 503 and a first air bag 504.
