Description

Technical Field

[0001] The present invention relates to the technical field of cardiology interventional auxiliary treatment, and in particular to a cardiology interventional treatment auxiliary support arm. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up by the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, irregular heartbeat, myocardial infarction, cardiomyopathy, myocarditis and acute myocardial infarction and other cardiovascular diseases. Currently, interventional treatment is used in many cases in cardiology treatment. Interventional treatment is a minimally invasive treatment that uses puncture needles, catheters and other interventional equipment to introduce specific instruments into the lesion site of the human body through natural channels or tiny incisions under the guidance and monitoring of imaging equipment such as digital subtraction angiography, CT, ultrasound and magnetic resonance imaging.

[0003] The existing auxiliary support arm for interventional treatment in cardiology can firmly fix the catheter during interventional treatment, thereby reducing the vibration or displacement that may occur during manual operation. However, it is inconvenient to automatically intervene or remove the catheter during intervention or removal, so that medical personnel are required to continuously intervene or remove the catheter. After the catheter is removed, it is inconvenient for auxiliary medical personnel to compress the puncture site of the patient to stop bleeding, thereby increasing the difficulty of operation for medical personnel and increasing the workload of medical personnel.

[0004] Combining the above problems, it is found that it is difficult to avoid the above problems at the same time when using the existing auxiliary support arms for interventional treatment of cardiology on the market, and even if they can be solved, they need to be solved through the cooperation of external tools, thus failing to achieve the desired effect.

[0037] See also Figure 5A placement rack 2119 is fixedly installed on the upper surface of the support frame 13, and a partition plate 2120 is fixedly installed on the inner wall of the placement rack 2119. By setting up the placement rack 2119, medical devices required for patient interventional treatment can be stored, so that it is convenient for personnel to take and use the medical devices. The partition plate 2120 can separate the placement rack 2119, so that the medical devices can be conveniently classified and placed.

[0038] See also Fig. 9 An electric telescopic rod 2121 is fixedly installed on the inner top wall of the base 11, and a grounding frame 2122 is fixedly installed on the telescopic end of the electric telescopic rod 2121. By setting the electric telescopic rod 2121, the grounding frame 2122 can be driven to move up and down, so that the grounding frame 2122 can contact the ground when in use, thereby preventing the universal wheel 14 from sliding at will, and facilitating medical staff to adjust the height of the device, ensuring the treatment operation of medical staff.

[0039] See also Figure 3 A limit bearing 2123 is fixedly installed on the right end of the first reciprocating screw rod 2116, and the right side surface of the limit bearing 2123 is fixedly connected to the inner wall of the support frame 13. The limit bearing 2123 can be used to limit and fix the first reciprocating screw rod 2116, thereby preventing the first reciprocating screw rod 2116 from shaking or deviating during rotation, thereby ensuring the stability of the first reciprocating screw rod 2116 during rotation.

[0040] See also Figure 4 A mounting frame 2124 is fixedly installed on the back of the support frame 13, and the inner wall of the mounting frame 2124 contacts the outer surface of the three-way hose 2110. The three-way hose 2110 can be limited by the mounting frame 2124, thereby preventing the three-way hose 2110 from accumulating and ensuring the normal transportation of gas.

[0041] The specific implementation of this embodiment is as follows: when the catheter needs to be intervened, the catheter is first passed through the movable frame 2101 and the fixed frame 2103, and the second solenoid valve 2112 is opened. The suction force provided by the suction pump 2109 can allow the gas to enter the first air bag 2102 through the first air inlet pipe 2111, so that the first air bag 2102 can expand in the movable frame 2101, thereby clamping and limiting the catheter. The power provided by the bidirectional motor 2115 can drive the first reciprocating screw rod 2116 to rotate clockwise, so that the first arc The block 2117 can drive the movable block 2118 to move, so that the clamped catheter can be transported. When the movable frame 2101 transports the catheter for a distance, the first solenoid valve 2106 opens, so that the air in the first airbag 2102 can be evacuated outward, so that the first airbag 2102 can release the clamping limit of the catheter. After the limit is released, the first reciprocating screw rod 2116 can drive the movable block 2118 to move to the right, and the fourth solenoid valve 2114 opens, so that the air pump 2109 can transport the gas to the second airbag 2104, and the first reciprocating screw rod 2116 can drive the movable block 2118 to move to the right, and the fourth solenoid valve 2114 opens, so that the air pump 2109 can transport the gas to the second airbag 2104. The second airbag 2104 expands to clamp and limit the catheter, thereby preventing the catheter from shaking when the movable frame 2101 moves to the right. When the movable frame 2101 intervenes in the catheter again, the third solenoid valve 2108 opens, allowing the air in the second airbag 2104 to be discharged from the second exhaust pipe 2107, thereby releasing the limit on the catheter. When the catheter needs to be taken out, contrary to the intervention operation, when the movable frame 2101 is on the left, the first airbag 2102 clamps the catheter, and the first reciprocating screw rod 2116 drives the catheter to move to the right. The movable frame 2101 moves so that the catheter can be pulled out. After the movable frame 2101 pulls the catheter out for a certain distance, the first airbag 2102 releases the limit on the catheter, and the second airbag 2104 clamps and limits the catheter to prevent the catheter from shaking when the movable frame 2101 moves to the left. The catheter can be automatically clamped and intervened and clamped and pulled out, so that the catheter can be automatically intervened and removed, so that there is no need for personnel to continuously intervene or remove the catheter, and continuous intervention or pulling out of the catheter can be prevented to prevent arm soreness, so as to reduce the difficulty of operation for medical personnel.
