Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an auxiliary positioning device based on puncture surgery. Background Art

[0002] Puncture, a commonly used surgical term in medicine, is a diagnostic and treatment technique of inserting a puncture needle into a body cavity to extract secretions for laboratory tests, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is to draw blood for laboratory tests, transfuse blood, infuse fluids, and insert a catheter for angiography, etc.

[0003] The femoral artery is the direct continuation of the external iliac artery. It originates from the posterior of the midpoint of the inguinal ligament, passes through the vascular lacuna to enter the femoral triangle, enters the adductor canal from the tip of the femoral triangle downward, passes through the adductor magnus tendon hiatus to reach the popliteal fossa, and continues as the popliteal artery.

[0004] The puncture point usually selected for femoral artery puncture is 2 - 3 fingers below the inguinal ligament. After local anesthesia by inserting a needle from the medial side of the femoral artery, when the pulsation of the femoral artery is touched, the needle is inserted for puncture. However, in the above traditional puncture technique, it is more dependent on the operator to confirm the puncture point by palpating the femoral artery pulsation, but there are the following problems. Obese patients have thicker subcutaneous fat, and the operator cannot well confirm the puncture point, which may lead to puncture failure. Then, multiple punctures are required. However, multiple punctures will cause hematoma or pseudoaneurysm at the puncture point, resulting in increased pain for the patient. Therefore, we urgently need an auxiliary positioning device based on puncture surgery to solve the above problems. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7 , the present invention provides a technical solution: an auxiliary positioning device for puncture surgery, including two bases 1. A placement plate 3 is fixedly installed on the two bases 1 through a moving component 2. Self-locking air springs 4 are fixedly installed on the left and right sides of the placement plate 3 by opening placement grooves. The output ends of the two self-locking air springs 4 are fixedly installed with insertion blocks 5, and a scanning and positioning assembly 6 is arranged on the placement plate 3.

[0032] The self-locking air spring 4 is filled with inert gas or oil-gas mixture in a sealed pressure cylinder, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure. By using the fact that the cross-sectional area of the piston rod is smaller than the cross-sectional area of the piston, a pressure difference is generated to realize the movement of the piston rod. Adding self-locking air springs 4 on both sides of the placement plate 3 can be used to adapt to various distances between the two bases 1. The two bases 1 are independently designed to facilitate adapting to the body shapes of obese people.

[0033] The moving component 2 includes a first electric guide rail 21. The two first electric guide rails 21 are respectively fixedly installed on the bases 1 on the left and right sides. Driving blocks 22 are slidably connected to the two first electric guide rails 21. Opposite sides of the two driving blocks 22 are fixedly connected with vertical rods 23. Second electric guide rails 24 are fixedly installed on opposite sides of the two vertical rods 23. Driving blocks 25 are slidably connected to the two second electric guide rails 24. One side of the insertion block 5 driving the insertion rod is inserted into the insertion groove opened on the driving block 25.

[0034] Both the first electric guide rail 21 and the second electric guide rail 24 use electrical signal transmission to drive the corresponding first driving block 22 and second driving block 25 to move. Both the first electric guide rail 21 and the second electric guide rail 24 are electrically connected to an external power supply control unit through a wire harness to attach Figure 2 For example, the first driving block 22 reciprocates in the Z-axis direction, and the second driving block 25 reciprocates in the Y-axis direction.

[0035] The scanning and positioning assembly 6 includes a controller 61. The controller 61 is fixedly installed on the upper surface of the placement plate 3. A display 62 is electrically connected to the controller 61 through a wire harness. An ultrasonic probe 63 is fixedly installed on the lower surface of the placement plate 3. The ultrasonic probe 63 is interconnected with the controller 61 through a wire harness. A first U-shaped frame 64 is fixedly installed at the rear side of the placement plate 3. A first servo motor 65 is fixedly installed on the first U-shaped frame 64. One end of a transmission rod 66 is fixedly installed at the output end of the first servo motor 65, and the other end of the transmission rod 66 extends inward into the first U-shaped frame 64 and is rotationally connected to a bearing in a corresponding bearing hole opened on the corresponding side surface of the first U-shaped frame 64. An installation bracket 67 is fixedly installed on the transmission rod 66. A near-infrared spectrum sensor 68 is fixedly installed on the installation bracket 67. The near-infrared spectrum sensor 68 is interconnected with the controller 61 through a wire harness.

[0036] It should be noted that the controller 61 is a common control unit for necessary functions such as power supply to components, action control, signal transmission and reception, etc., so it will not be elaborated here. The ultrasonic probe 63 is used to obtain the cross-sectional image of the patient's blood vessels. The near-infrared spectrum sensor 68 can achieve angular movement through the cooperation of the first servo motor 65, the transmission rod 66 and the installation bracket 67, and is used to detect the difference in the concentration of oxyhemoglobin in subcutaneous blood vessels.

[0037] A second U-shaped frame 69 is fixedly installed at the front side of the placement plate 3. A second servo motor 610 is fixedly installed on the second U-shaped frame 69. One end of a transmission rod 611 is fixedly installed at the output end of the second servo motor 610, and the other end of the transmission rod 611 extends inward into the second U-shaped frame 69 and is rotationally connected to a bearing in a corresponding bearing hole opened on the corresponding side surface of the second U-shaped frame 69. A joint arm 612 is fixedly installed on the transmission rod 611. The joint arm 612 is interconnected with the controller 61 through a wire harness. A rectangular block 613 is fixedly installed on the end arm of the joint arm 612. Sliding grooves 614 are opened on the left and right sides of the rectangular block 613. Two sliders 615 are slidably connected in the two sliding grooves 614 through guide rails. A third U-shaped frame 616 is fixedly connected to the two sliders 615. An arc-shaped clamping plate 617 is hinged on the two third U-shaped frames 616 through a rotating rod.

[0038] The articulated arm 612 is a common component that can simulate a human arm. The angle of the lower swing arm is driven and adjusted by a joint motor at its joint, and in cooperation with the second servo motor 610 and the second transmission rod 611, the positioning of the upper and lower swing arms of the articulated arm 612 is made more accurate.

[0039] Threaded holes 618 are provided on two arc-shaped clamping plates 617, and threaded limit is carried out through a screw rod 619 and a nut 620. A fixed tube 621 is arranged between the two arc-shaped clamping plates 617, and a visual probe 622 is fixedly installed on the fixed tube 621.

[0040] The fixed tube 621 is used for sleeving a puncture needle tube. Since the angle of the fixed tube 621 is the positioning angle after the puncture point is confirmed, therefore, the needle tube can be directly placed in the fixed tube 621 at the same inclination angle, so as to ensure the accuracy of the puncture point. The visual probe 622 is Bluetooth-transmitted, transmits the signal to the controller 61, and then is transmitted to the display 62 by the controller 61, which is convenient for medical staff to view.

[0041] Working principle: When the puncture surgery-based auxiliary positioning device works, medical staff place the two bases 1 on both sides of the patient's leg and adjust the distance. The output ends of the self-locking air springs 4 on both sides of the placement plate 3 are pulled out and inserted into the insertion slots on the driving block 25 through the insertion blocks 5. After the insertion is fixed, the fixation of the placement plate 3 is completed. At this time, the placement plate 3 is located above the patient's leg;

[0042] In the first inspection, the operator controls the driving block two 25 on the second electric guide rail 24 to move downward. The placement plate 3 will move downward following the driving block two 25 until the ultrasonic probe 63 contacts the patient's leg. Then, the driving block one 22 on the first electric guide rail 21 will drive the placement plate 3 to perform a reciprocating motion. When the placement plate 3 moves, the ultrasonic probe 63 starts and scans the patient's leg to obtain the cross-sectional image of the blood vessel at the puncture site. After the image is transmitted to the display 62, the driving block two 25 on the second electric guide rail 24 will drive the placement plate 3 to move upward, separating the ultrasonic probe 63 from the patient's leg;

[0043] At this time, the first servo motor 65 on the first U-shaped frame 64 drives the first transmission rod 66 to rotate. After the near-infrared spectrum sensor 68 on the mounting frame 67 rotates to the detection position, the first electric guide rail 21, the driving block one 22, and the driving block two 25 on the second electric guide rail 24 move. The driving block two 25 drives the placement plate 3 to move downward, and the driving block one 22 drives the placement plate 3 to move, so that the near-infrared spectrum sensor 68 can completely scan the puncture site of the patient's leg, thereby obtaining the detected difference value of the oxyhemoglobin concentration in the subcutaneous blood vessels and synchronously transmitting the data to the display 62;

[0044] After both pieces of data are fully displayed on the display 62, the electric guide rail 1 21 drives the driving block 1 22 to move. After the fixed tube 621 moves to near the puncture point, the servo motor 2 610 drives the transmission rod 2 611 to preliminarily adjust the articulated arm 612. After the position of the fixed tube 621 is closer to the puncture point, through the fine adjustment at the joint of the articulated arm 612 and in cooperation with the electric guide rail 1 21 and the electric guide rail 2 24 to drive the corresponding driving block 1 22 and the driving block 2 25 to adjust the position of the placement plate 3, so that the fixed tube 621 moves and positions the puncture point, and after adjusting the inclination angle of the needle insertion, the medical staff can place the syringe in the fixed tube 621 and cooperate with the visual probe 622 to puncture the patient. It should be noted that during the puncture process, the articulated arm 612, the electric guide rail 1 21 and the electric guide rail 2 24 will also move accordingly. This movement data is calculated by the controller 61 and is used to assist the medical staff in puncturing;

[0045] When the screw 619 is turned and the nut 620 is removed, the two arc-shaped clamping plates 617 can move, and the fixed tube 621 can be taken out.
