Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an automated device. Background Technology

[0002] Mitral regurgitation is usually caused by incomplete closure of the mitral valve, allowing blood to flow back into the left atrium. Treatment methods include general treatment, medication, and surgery. Generally, if the mitral regurgitation is not severe and there are no obvious symptoms, no special treatment is needed; regular checkups as prescribed by a doctor are sufficient. During this time, it is important to rest more and avoid strenuous exercise to prevent increasing the burden on the heart. If mitral regurgitation causes uncomfortable symptoms such as shortness of breath or wheezing, medications such as sodium nitroprusside, spironolactone, and furosemide can be used as prescribed by a doctor to dilate blood vessels, reduce cardiac load, and relieve related discomfort. For some severe cases of mitral regurgitation that do not respond well to the above treatments, surgical treatment may be considered, including mitral valve repair or valve replacement.

[0003] Currently, during mitral valve repair surgery, the bending device is usually adjusted manually by the doctor. The adjustment and the position of the bending device need to be adjusted based on the doctor's experience. Manual adjustment is prone to over-rushing, which can cause the bending wire in the catheter to break due to excessive tension. Summary of the Invention

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-2 As shown, this embodiment provides an automated device, including a support 1 for supporting a bending device 5. The bending device 5 is provided with a conduit 51 for conveying the bending wire. It also includes an inflation negative pressure mechanism 2, which is used to inject physiological saline into the bending device 5 during surgery to prevent blood clotting. It can also adjust the pressure of the conduit 51 while rotating to prevent air from entering the conduit 51 and improve the safety of the surgery.

[0021] An adjustment mechanism 3 is also provided, which is installed at the front end of the bracket 1 and is used to adjust the position of the bending device 5.

[0022] It also includes a foolproof mechanism 4, which limits the rotation angle of the bending device 5 to prevent the bending wire in the guide tube 51 from being too tight during the bending process of the bending device 5, which could lead to breakage.

[0023] In a specific embodiment, the inflation negative pressure mechanism 2 includes an air pump 22, which is connected to an air supply pipe 23. The other end of the air supply pipe 23 is connected to a Luer connector 24, and the Luer connector 24 is connected to a conduit 51 through a connector.

[0024] Furthermore, a pressure sensor can be installed in the gas supply pipe 23. The pressure sensor is connected to the control unit, and the control unit is connected to the air pump 22 to realize the opening and closing of the air pump 22.

[0025] The pressure sensor monitors the pressure inside the gas delivery tube 23 and the catheter 51. When outside air enters the catheter 51, the pressure sensor detects an increase in the internal pressure of the catheter 51 and outputs a signal to the control unit. The control unit controls the air pump 22 to operate, drawing out the pressure inside the catheter 51 to prevent excessive pressure inside the catheter 51. When the pressure sensor detects that the internal pressure of the catheter 51 reaches the pressure range required for the operation, it outputs a signal to the control unit, which controls the air pump 22 to stop, thereby regulating the internal pressure of the catheter 51 and improving the safety of the operation.

[0026] In other embodiments, the air pump 22 can also be a peristaltic pump. The peristaltic pump is connected to the Luer connector 24 via a connecting hose. The peristaltic pump outputs the gas in the conduit 51, preventing the gas-liquid mixture inside the conduit 51 from being discharged from the Luer connector 24 at the same time during use. This avoids damage to the conventional air pump 22 and extends the service life of the equipment.

[0027] The air-filled negative pressure mechanism 2 also includes a reservoir 21, which is used to store heparinized saline. The reservoir 21 is connected to the inlet of the reservoir pump 25 through a second water pipe 27. The outlet of the reservoir pump 25 is connected to a Luer connector 24 through a first water pipe 26. The Luer connector 24 is connected to a conduit 51. When the reservoir pump 25 is started, the heparinized saline in the reservoir 21 is drawn into the conduit 51 through the first water pipe 26 and the second water pipe 27, and then into the patient's body through the conduit 51, which has the effect of preventing coagulation.

[0028] In this embodiment, the Luer connector 24 can be a three-way Luer connector, with one interface connected to the first water pipe 26 and the other interface connected to the gas supply pipe 23. During the operation, the Luer connector 24 is opened to connect with the first water pipe 26, and the heparinized saline in the reservoir 21 is drawn into the catheter 51 by the reservoir pump 25. The Luer connector 24 is opened to connect with the gas supply pipe 23, and the air is drawn out of the catheter 51 by the air pump 22 to maintain the pressure balance in the catheter 51.

[0029] In other embodiments, two straight-through Luer connectors 24 may be provided, both of which are connected to the conduit 51. One Luer connector 24 is connected to the first water pipe 26, and the other Luer connector 24 is connected to the air supply pipe 23. Air is drawn out of the conduit 51 by the air pump 22, and heparinized saline is injected into the conduit 51 by the liquid storage pump 25.

[0030] In this embodiment, the adjustment mechanism 3 includes a first driving member 33, which is fixed on the bracket 1. The first driving member 33 is connected to a worm gear 34, which meshes with a worm wheel 35. The worm wheel 35 is connected to a rotating shaft 351, which is connected to a support frame 31 via a bearing.

[0031] It also includes a rotating frame 32, one end of which is fixedly connected to a rotating shaft 351. When the first driving member 33 is activated, it drives the worm gear 34 to rotate, which in turn drives the worm wheel 35 and the rotating shaft 351 to rotate. The rotating frame 32 rotates synchronously. The first driving member 33 rotates in both the forward and reverse directions to drive the rotating frame 32 to rotate left and right, and to adjust the rotation angle of the rotating frame 32.

[0032] It also includes a movable frame 36, which is located above the rotating frame 32. Fasteners 361 are installed on both sides of the movable frame 36. The bending device 5 is placed on the movable frame 36, and the bending device 5 is fixed by rotating the fasteners 361.

[0033] Furthermore, a support rod 310 is fixedly connected to the lower end face of the movable frame 36, and a lead screw nut 39 is fixedly connected to the other end of the support rod 310. The lead screw nut 39 is connected to the lead screw 38, one end of the lead screw 38 is connected to the second drive member 37, the second drive member 37 is fixed to the lower end face of the rotating frame 32, and the other end of the lead screw 38 is connected to the bearing bracket (not shown in the figure) through a bearing. The bearing bracket is fixed to the lower end face of the rotating frame 32.

[0034] In this embodiment, the rotating frame 32 has a U-shaped hole 321 corresponding to the support rod 310, and the support rod 310 passes through the U-shaped hole 321.

[0035] In another embodiment, a slider is fixed on the support rod 310, and a groove is provided on one side of the U-shaped hole 321. The slider slides along the groove to limit the support rod 310.

[0036] Specifically, the second drive unit 37 is activated to drive the lead screw 38 to rotate in the forward and reverse directions, causing the lead screw nut 39 to move back and forth along the lead screw 38, thereby driving the movable frame 36 to move back and forth.

[0037] In this embodiment, the first drive unit 33 and the second drive unit 37 can be servo motors, which can improve accuracy.

[0038] Please see Figures 4-5 In this embodiment, the foolproof mechanism 4 includes a support column 41, which is fixed on the support frame 31. The upper end of the support frame 31 is provided with a limiting groove 311, and the bottom end face of the limiting groove 311 is arc-shaped to support the guide tube 51. When the rotating frame 32 rotates, the guide tube 51 moves along the bottom end face of the limiting groove 311, thereby improving the stability of the movement of the guide tube 51.

[0039] In another embodiment, the top of the limiting groove 311 is a smooth arc surface, which supports the conduit 51 while reducing the friction between the conduit 51 and the conduit 51.

[0040] The foolproof mechanism 4 also includes a knob 42, which is connected to an adjusting screw 43. The support column 41 has a threaded hole corresponding to the adjusting screw 43. The adjusting screw 43 is screwed into the threaded hole. The other end of the adjusting screw 43 is connected to a limiting block 44, which is located inside the limiting groove 311.

[0041] Specifically, rotating the knob 42 drives the adjusting screw 43 to rotate, which can adjust the position of the limiting block 44 in the limiting groove 311. There are two limiting blocks 44, and both limiting blocks 44 are connected to the adjusting screw 43. The adjusting screw 43 is threadedly connected to the support column 41. The two limiting blocks 44 limit the guide tube 51, and prevent the bending thread in the guide tube 51 from being too tight and breaking during the bending process of the bending device, thus avoiding product failure.

[0042] In use, the front end of the bending device 5 is placed on the movable frame 36, and the fastener 361 is tightened to fix the bending device 5 on the movable frame 36. The guide tube 51 is placed in the limiting groove 311. During the operation, the first driving component 33 is activated to drive the worm gear 34 to rotate, which in turn drives the worm wheel 35 and the rotating shaft 351 to rotate, driving the rotating frame 32 to rotate. The first driving component 33 can rotate in both the forward and reverse directions to adjust the left and right rotation angle of the rotating frame 32. The second driving component 37 is activated to drive the lead screw 38 to rotate, which drives the lead screw nut 39 to move along the lead screw 38, driving the support rod 310 and the movable frame 36 to move back and forth, thereby adjusting the forward and backward movement of the bending device 5, greatly reducing the difficulty of the operation.

[0043] It is understandable that controlling the forward and reverse rotation of the first driving member 33 and the second driving member 37 through a computer program, and controlling the rotation angle of the first driving member 33 and the second driving member 37 through an electromagnetic relay, can be obtained by those skilled in the art through conventional experimental methods, and will not be elaborated here.

[0044] During the procedure, if an increase in pressure is detected inside catheter 51, air pump 22 is activated to remove air from catheter 51 and adjust the pressure inside catheter 51. Liquid pump 25 draws heparinized saline from liquid reservoir 21 and injects it into catheter 51 before it is administered to the patient, which can prevent blood clotting.

[0045] The foolproof mechanism 4 has a foolproof function. During the bending process of the bending device 5, it prevents the bending wire in the guide tube 51 from being too tight and breaking, thus avoiding product failure.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
