Description

Technical Field

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

[0002] Cardiology, that is, cardiovascular medicine, is a clinical department set up in 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, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, and acute myocardial infarction, etc. In current cardiology treatment, in many cases, interventional treatment is adopted. Interventional treatment is to use puncture needles, catheters and other interventional devices to introduce specific instruments into the diseased parts of the human body through natural orifices or tiny incisions in the human body under the guidance and monitoring of imaging devices such as digital subtraction angiography machines, CT, ultrasound, and magnetic resonance for minimally invasive treatment.

[0003] The existing interventional treatment auxiliary support arm for cardiology can firmly fix the catheter during interventional treatment, thereby reducing the tremor or displacement that may occur during manual operation. However, when inserting or removing the catheter, it is not convenient to automatically insert or remove the catheter, which requires medical staff to continuously insert or pull out the catheter. And after the catheter is pulled out, it is not convenient to assist the medical staff to compress and stop bleeding at the puncture site of the patient, thus increasing the operation difficulty of the medical staff while also increasing the work intensity of the medical staff.

[0004] Combined with the above problems, it will be found that the existing interventional treatment auxiliary support arm for cardiology on the current market is very difficult to avoid the above-mentioned problems simultaneously during use. And even if it can be solved, it needs to be solved by cooperating with external tools, thus unable to achieve the desired effect.

[0035] The interventional extraction mechanism 2 includes a clamping and moving unit 21. The clamping and moving unit 21 is located above the support frame 13 and is used for the intervention and extraction of the catheter.

[0036] As a further limitation of the intervention and extraction mechanism 2 of the present invention, the clamping and moving unit 21 includes a moving frame 2101. The bottom surface of the moving frame 2101 is slidably connected to the upper surface of the support frame 13. A first airbag 2102 is fixedly installed on the inner wall of the moving frame 2101.

One end of the second intake pipe 2113 penetrates through the fixed frame 2103 and is fixedly communicated with the outer surface of the second airbag 2104. A fourth solenoid valve 2114 is fixedly communicated with the outer surface of the second intake pipe 2113. A bidirectional motor 2115 is fixedly installed on the inner bottom wall of the support frame 13. The output end of the power of the bidirectional motor 2115 is fixedly installed with a first reciprocating lead screw 2116. A first arc-shaped block 2117 is slidably connected to the outer surface of the first reciprocating lead screw 2116. A moving block 2118 is fixedly installed on the back surface of the first arc-shaped block 2117. The outer surface of the moving block 2118 is slidably connected to the inner wall of the support frame 13. The upper surface of the moving block 2118 is fixedly connected to the bottom surface of the moving frame 2101. Through the clamping and moving unit 21 of the intervention and extraction mechanism 2, the catheter for cardiovascular medicine treatment can be automatically clamped and pushed and clamped and pulled outwards, so that the catheter for cardiovascular medicine treatment can be automatically intervened and extracted, thus eliminating the need for personnel to continuously intervene or extract the catheter for cardiovascular medicine treatment, preventing arm soreness caused by continuous intervention or pulling by personnel, and reducing the operation difficulty of medical staff.

[0037] Please refer to Figure 5, a 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 providing the placement rack 2119, medical devices required for patient interventional treatment can be stored, facilitating personnel to pick up and use the medical devices. The partition plate 2120 can partition the placement rack 2119, enabling convenient classification and placement of medical devices.

[0038] Please refer to Figure 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 at the telescopic end of the electric telescopic rod 2121. By providing the electric telescopic rod 2121, it can drive the grounding frame 2122 to move up and down, enabling the grounding frame 2122 to contact the ground during use, preventing the universal wheels 14 from sliding randomly, and facilitating medical staff to adjust the height of the device, ensuring the treatment operations of medical staff.

[0039] Please refer to Figure 3 , a limit bearing 2123 is fixedly installed at the right end of the first reciprocating lead screw 2116, and the right side surface of the limit bearing 2123 is fixedly connected to the inner side wall of the support frame 13. Through the limit bearing 2123, the first reciprocating lead screw 2116 can be limited and fixed, preventing the first reciprocating lead screw 2116 from shaking and offsetting during rotation, ensuring the stability of the first reciprocating lead screw 2116 during rotation.

[0040] Please refer to Figure 4 , an installation frame 2124 is fixedly installed on the back surface of the support frame 13, and the inner wall of the installation frame 2124 is in contact with the outer surface of the three-way hose 2110. Through the installation frame 2124, the three-way hose 2110 can be limited, preventing the three-way hose 2110 from accumulating and ensuring the normal transmission of gas.

[0041] The specific implementation of this embodiment is as follows: When catheter intervention is required, first pass the catheter through the movable frame 2101 and the fixed frame 2103. Open the second solenoid valve 2112. The suction force provided by the air pump 2109 can cause gas to enter the first airbag 2102 through the first air inlet pipe 2111, enabling the first airbag 2102 to 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 lead screw 2116 to rotate clockwise, causing the first arc-shaped block 2117 to drive the movable block 2118 to move, thereby conveying the clamped catheter. When the movable frame 2101 conveys the catheter a certain distance, the first solenoid valve 2106 is opened, allowing the air in the first airbag 2102 to disperse outward, so that the first airbag 2102 can release the clamping and limiting of the catheter. After the limit is released, the first reciprocating lead screw 2116 can drive the movable block 2118 to move to the right. The fourth solenoid valve 2114 is opened, enabling the air pump 2109 to convey gas to the second airbag 2104. The expansion of the second airbag 2104 can 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 is opened, allowing the air in the second airbag 2104 to be discharged outward from the second exhaust pipe 2107, thereby releasing the limit on the catheter. When the catheter needs to be removed, contrary to the intervention operation, when the movable frame 2101 is on the left side, the first airbag 2102 clamps the catheter, and the first reciprocating lead screw 2116 drives the catheter to move to the right, thereby pulling out the catheter. When the movable frame 2101 pulls out the catheter 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. Thus, automatic clamping intervention and outward clamping and pulling of the catheter can be achieved, enabling automatic intervention and removal of the catheter, so that there is no need for personnel to continuously intervene or remove the catheter, preventing arm soreness caused by continuous personnel intervention or pulling, and reducing the operation difficulty of medical staff.

[0042] Embodiment 2: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , the present invention provides a technical solution: a cardiology intervention treatment auxiliary support arm.

[0043] As a further limitation of the intervention extraction mechanism 2 of the present invention, the compression hemostasis unit 22 includes a limit frame 2201.

A sliding block 2211 is fixedly installed on the left side surface of the second arc-shaped block 2210. The outer surface of the sliding block 2211 is slidably connected to the inner wall of the limit frame 2201. A moving block 2212 is fixedly installed on the left side surface of the sliding block 2211. A cylinder 2213 is fixedly installed on the bottom surface of the moving block 2212. A compression frame 2214 is fixedly installed on the bottom surface of the cylinder 2213. A third airbag 2215 is fixedly installed on the inner wall of the compression frame 2214. An air supply hose 2216 is fixedly communicated with the outer surface of the three-way hose 2110. One end of the air supply hose 2216 sequentially penetrates through the moving block 2212 and the compression frame 2214 and is fixedly communicated with the outer surface of the third airbag 2215. The outer surface of the air supply hose 2216 is fixedly connected to the inner wall of the cylinder 2213. A fifth solenoid valve 2217 is fixedly communicated with the outer surface of the air supply hose 2216. An air outlet pipe 2218 is fixedly communicated with the outer surface of the third airbag 2215. One end of the air outlet pipe 2218 penetrates through the compression frame 2214 and extends to the outside of the compression frame 2214. A sixth solenoid valve 2219 is fixedly communicated with the outer surface of the air outlet pipe 2218. By providing the compression hemostasis unit 22, it is possible to assist medical staff in compressing and stopping bleeding at the puncture site of the patient after the catheter is pulled out, so that it is not necessary for medical staff to continuously press and stop bleeding at the puncture site after the catheter is pulled out, thereby reducing the operation difficulty of medical staff while also reducing the work intensity of medical staff.

[0044] Please refer to Figure 6 A connecting frame 2220 is fixedly installed on the bottom surface of the moving block 2212. A lighting lamp 2221 is fixedly installed on the bottom surface of the connecting frame 2220. By providing the connecting frame 2220, the lighting lamp 2221 can be limited, so that the lighting lamp 2221 can provide illumination for medical staff, thereby facilitating the operation of medical staff.

[0045] The specific implementation of this embodiment is as follows: After the catheter is removed, the medical staff place the gauze at the puncture site of the patient. The bidirectional motor 2115 drives the one-way bearing 2202 to rotate in the reverse direction, so that the one-way bearing 2202 can drive the first gear 2203 to rotate. The rotation of the first gear 2203 can drive the first transmission belt 2205 to rotate, so that the second gear 2204 can drive the movable rod 2206 to rotate. The rotation of the movable rod 2206 can drive the first bevel gear 2207 to rotate, so that the first bevel gear 2207 can drive the second bevel gear 2208 to rotate. The rotation of the second bevel gear 2208 can drive the second reciprocating lead screw 2209 to rotate, so that the second reciprocating lead screw 2209 can drive the second arc-shaped block 2210 to move up and down, thereby driving the compression frame 2214 to compress the puncture site of the patient. The fifth solenoid valve 2217 is opened, so that the air pump 2109 can transport the gas through the air delivery hose 2216 to the third airbag 2215. The third airbag 2215 can compress and stop bleeding at the puncture site of the patient. The sixth solenoid valve 2219 can discharge the air in the third airbag 2215 to the outside, thereby reducing the pressure in the third airbag 2215, enabling tight compression at the initial stage of hemostatic compression, gradually reducing the compression force during the later hemostasis process, gradually buffering and releasing the hemostatic pressure, ensuring the normal circulation of blood, improving the hemostatic effect, and thus assisting the medical staff to compress and stop bleeding at the puncture site of the patient after the catheter is pulled out. Therefore, after the catheter is pulled out, it is not necessary for the medical staff to continuously press and stop bleeding at the puncture site, thereby reducing the operation difficulty of the medical staff and also reducing the work intensity of the medical staff.

The bottom surface of each clamping frame 301 is slidably connected to the upper surface of the support frame 13. A third gear 302 is fixedly installed on the outer surface of the power output end of the bidirectional motor 2115. A rotating rod 305 is rotatably connected to the outer surface of the support frame 13. A fourth gear 303 is fixedly installed on the outer surface of the rotating rod 305. A second transmission belt 304 is commonly engaged with the outer surfaces of the third gear 302 and the fourth gear 303. A third bevel gear 306 is fixedly installed at the left end of the rotating rod 305. A fourth bevel gear 307 is engaged with the outer surface of the third bevel gear 306. A threaded lead screw 308 is fixedly installed on the upper surface of the fourth bevel gear 307. A push frame 309 is arranged inside the support frame 13. The inner wall of the push frame 309 is threadedly connected to the outer surface of the threaded lead screw 308. The outer surface of the threaded lead screw 308 is rotatably connected to the inner wall of the support frame 13. A connecting rod 310 is fixedly installed on the left side surface of the third bevel gear 306. A worm 311 is fixedly installed at the left end of the connecting rod 310. A worm gear 312 is engaged with the outer surface of the worm 311. A bidirectional threaded rod 314 is fixedly installed inside the worm gear 312. Both ends of the bidirectional threaded rod 314 are rotatably connected to the inner wall of the support frame 13. Two movable plates 313 are slidably connected to the inner wall of the support frame 13. The inner walls of the two movable plates 313 are both threadedly connected to the outer surface of the bidirectional threaded rod 314. The upper surface of each movable plate 313 is fixedly connected to the bottom surface of the clamping frame 301. By providing the limiting mechanism 3, the arm of the patient can be limited and fixed during puncture or catheter intervention and removal, thereby preventing the patient's arm from shaking during puncture or catheter intervention and removal, enabling the medical staff to support the patient's arm while also preventing secondary injury to the patient caused by arm shaking.

[0048] Please refer to Figure 7 and Figure 8 Each clamping frame 301 has a first rubber pad 315 fixedly installed on its inner wall. A second rubber pad 316 is fixedly installed on the outer surface of the push frame 309. The outer surface of the second rubber pad 316 is slidably connected to the inner wall of the support frame 13. The first rubber pad 315 can protect the clamped patient's arm, thereby preventing discomfort caused by excessive clamping. The second rubber pad 316 can increase the comfort of the patient's wrist, ensuring the comfort of the patient during treatment.

[0049] The specific implementation of this embodiment is as follows: The power provided by the bidirectional motor 2115 can drive the third gear 302 to rotate clockwise, so that the third gear 302 can drive the second transmission belt 304 to rotate, and the second transmission belt 304 can drive the fourth gear 303 to rotate, thereby driving the rotating rod 305 to rotate. The rotation of the rotating rod 305 can drive the third bevel gear 306 to rotate, the rotation of the third bevel gear 306 can drive the fourth bevel gear 307 to rotate, and the rotation of the fourth bevel gear 307 can drive the threaded lead screw 308 to rotate, so that the threaded lead screw 308 can drive the push frame 309 to move upward, enabling the push frame 309 to lift the patient's wrist, which is convenient for medical staff to perform puncture and catheter intervention to remove. The rotation of the third bevel gear 306 can drive the connecting rod 310 to rotate, so that the connecting rod 310 can drive the worm 311 to rotate, the rotation of the worm 311 can drive the worm gear 312 to rotate, so that the worm gear 312 can drive the bidirectional threaded rod 314 to rotate, and the rotation of the bidirectional threaded rod 314 can drive the movable plate 313 to move. The movement of the movable plate 313 can drive the two clamping frames 301 to approach, thereby clamping and limiting the patient's arm. By driving the third gear 302 to rotate counterclockwise by the bidirectional motor 2115, the rotating rod 305 can be driven to rotate in the reverse direction, so that the third bevel gear 306 can drive the fourth bevel gear 307 to rotate in the reverse direction, and thus the threaded lead screw 308 can drive the push frame 309 to move downward. The reverse rotation of the connecting rod 310 can drive the worm 311 to rotate in the reverse direction, so that the worm gear 312 can drive the bidirectional threaded rod 314 to rotate in the reverse direction, and the clamping frames 301 can be separated from each other, enabling the limitation of the patient's arm to be released. Therefore, the patient's arm can be limited and fixed during puncture or catheter intervention and removal, preventing the patient's arm from shaking during puncture or catheter intervention and removal, so that while assisting medical staff in supporting the patient's arm, it can also prevent secondary harm to the patient caused by arm shaking.
