Description

Technical Field

[0001] The present invention relates to the technical field of cardiovascular interventional devices, and in particular to a CRT coronary sinus sheath device. Background Art

[0002] Cardiac resynchronization therapy (CRT) is an effective means of treating heart failure. It adds left ventricular pacing to the traditional dual-chamber pacing. Left ventricular pacing is achieved by passing an electrode through the coronary sinus opening of the right atrium, entering the posterior wall branch of the left ventricle of the coronary vein, and pacing the left ventricle. Pacing with left and right ventricular electrodes can restore synchronous ventricular contraction and reduce mitral regurgitation.

[0003] The specific operation process is to first select the left subclavian vein to puncture and insert the guide wire, and then send the long coronary sinus sheath into the coronary sinus through the guide wire. First, retrograde coronary sinus angiography should be performed to understand the direction of the coronary sinus and its branch vessels, and then the coronary sinus electrode wire should be inserted into the cardiac vein branch. After the left ventricular electrode wire is inserted into the venous branch through the coronary sinus, the left ventricular pacing threshold is tested, and the left ventricular electrogram and surface electrocardiogram are recorded. In addition, high-voltage stimulation should be performed to detect whether there is phrenic nerve stimulation. Finally, the right atrium and right ventricle electrode wires are implanted to test the pacing thresholds of the right atrium, right ventricle and biventricular heart, respectively. After the test is satisfactory, the electrode wire is connected to the pulse generator and then buried in the subcutaneous pouch on the left chest of the patient.

[0004] However, in actual surgery, due to changes in the heart structure of patients with heart failure, it is difficult to get the sheath into the coronary sinus during CRT surgery, which sometimes takes half an hour or even an hour to complete. Secondly, the left ventricular electrode needs to be placed in the lateral vein. When the lateral vein is small or the lateral vein opening is tortuous, the sheath usually used does not have enough support, making it difficult to place the left ventricular electrode. Patients who undergo CRT surgery often have severe heart failure and relatively low tolerance for surgery time, which can easily lead to surgery failure due to the long operation time.

[0029] like Figure 1-3 As shown, a CRT coronary sinus sheath device provided by the present invention comprises a plurality of sub-tubes 7 and a control end 5, wherein each of the sub-tubes 7 is electromagnetically connected end to end in sequence;

[0030] The sub-tube 7 includes a spherical tube body, a plurality of first electromagnetic sheets 8 are evenly arranged on the surface of the tube body, a channel 1 for penetrating the electrode is opened in the axial direction of the tube body, a first processor and a first power supply are also arranged in the tube body, a camera 9 is also arranged on the tube body at the head end, the tube body at the tail end is connected to the control end 5 through a connecting line 6, and the first processor signal of each sub-tube 7 is connected;

[0031] The control end 5 includes a body, in which a second power supply is arranged, and the second power supply is used to supply power to the first power supply, and the first power supply of each of the sub-tubes 7 is electrically connected to the second power supply in sequence;

[0032] The first processor on the sub-tube 7 located at the head end receives the image captured by the camera 9, and determines the direction of the venous sinus based on the image captured by the camera 9, and controls the first electromagnetic plate 8 according to the direction of the venous sinus, so that there is a bending angle between two adjacent sub-tubes 7, and determines the advancement speed of the sub-tube 7 according to the image captured by the camera 9, and sends the bending angle and the time corresponding to the bending angle to the first processors of other sub-tubes 7 according to the speed; the first processor of the sub-tube 7 located at the non-head end controls the first electromagnetic plate 8 at the time corresponding to the complete angle based on the received bending angle and the time corresponding to the bending angle, so that there is the bending angle between two adjacent sub-tubes 7.

[0033] The device of the present invention is manufactured using tiny electronic components. The diameter of the sub-tube 7 is less than 2.5 mm, the diameter of the connecting wire 6 is 1 mm, and the size of the control terminal 5 is similar to that of an ordinary mobile phone. Figure 1 The drawing only shows some of the sub-tubes 7 for illustrative purposes. In the device actually used, the number of the sub-tubes 7 ranges from thirty to forty or even fifty, which is determined according to the size of the sub-tubes 7.

[0034] When the present invention is in use, the doctor places the sub-tube 7 into the venous sinus and slowly pushes it forward, holding the control end during the pushing. The present invention transmits information between the sub-tubes 7, and the sub-tube 7 located at the head end judges the direction of the front, and determines the angle to be presented by the current sub-tube 7 and the adjacent sub-tube 7 according to the direction, that is, the bending angle. One position corresponds to one bending angle, and the bending angle is an angle in a three-dimensional space. Therefore, the sub-tube 7 of the present invention is spherical, and the judgment method is an image processing method. At the same time, the pushing speed is judged according to the image processing method, so that the time when the subsequent sub-tube 7 arrives at that place can be known. After arriving, the bending angle at this place needs to be used so that the sub-tube 7 at this place and its adjacent sub-tube 7 present the bending angle. Therefore, during the pushing process, the sub-tubes 7 of the device of the present invention are always in a changing process from a macroscopic perspective.

[0035] At the same time, in order to save electric energy, in the present invention, the first power supply in the sub-tube 7 is powered by the second power supply, and it is only necessary to connect the channel 1 of each sub-tube 7 through a wire. The wire can also be used for signal transmission between the first processors, and can also be used for model transmission between the second processor of the subsequent control end and each first processor.

[0036] During the operation, after the device reaches the appropriate position, the doctor inserts the electrode through the channel 1 of the sub-tube 7 to carry out subsequent work. In order to facilitate the work, the present invention can connect a soft tube between the two sub-tube 7 channels 1 to prevent the position of the electrode from deviating.

[0037] In order to facilitate the delivery of the electrode, the inner wall of the channel 1 of the sub-tube 7 is further provided with a plurality of second electromagnetic sheets 2, and the second electromagnetic sheets 2 are sequentially distributed along the direction of the channel 1;

[0038] The first processor on the sub-tube 7 at the tail end and the first processor on the sub-tube 7 at the head end control the second electromagnetic sheets 2 thereon to be turned on and off in sequence from the tail to the head, in a reciprocating cycle.

[0039] The second electromagnetic sheet 2 on each sub-tube 7 is opened once from the tail to the head and then closed, which can form an attractive pull for the electrode, and the pulling force changes from the tail to the head. When the electrode is placed, the electrode can automatically go to the sub-tube 7 at the head end, which is convenient and quick.

[0040] At the same time, in order to further optimize the above-mentioned effect, a connecting rod 10 is further provided outside the sub-tube 7 at the head end, and a second electromagnetic sheet 2 is provided at the rod head of the connecting rod 10;

[0041] The first processor on the sub-tube 7 at the head end controls the second electromagnetic sheet 2 on the connecting rod 10 so that it and other second electromagnetic sheets 2 are opened and closed in a reciprocating cycle.

[0042] The present invention allows the electrode to eventually extend out of the sub-tube 7 at the head end, facilitating subsequent surgical work.

[0043] In addition, the edges of two adjacent first electromagnetic sheets 8 on the sub-tube 7 are in contact, thereby achieving angle adjustment in multiple three-dimensional directions. There are multiple cameras 9, and the multiple cameras 9 are evenly distributed on the edge tube body of the channel 1. Multiple cameras 9 can make the collected data more accurate.

[0044] In the present invention, the control terminal 5 can also be improved and optimized, and the control terminal 5 is provided with a display screen 3, a position adjustment operation terminal 4, and a first and a second processor;

[0045] The first processor of the sub-tube 7 located at the head end transmits the picture taken by the camera 9 to the second processor, and the second processor sends the picture taken by the camera 9 to the display screen 3 for display;

[0046] The second processor receives the input of the position adjustment operating terminal 4, determines the bending angle, and sends the bending angle to the first processor of the sub-tube 7 located at the head end. The first processor of the sub-tube 7 located at the head end controls the first electromagnetic plate 8 so that there is a bending angle between two adjacent sub-tubes 7, and judges the advancement speed of the sub-tube 7 according to the picture taken by the camera 9, and sends the bending angle and the time corresponding to the bending angle to the first processors of other sub-tubes 7 according to the speed.

[0047] The present invention adds a control terminal 5. The doctor can watch the situation inside the venous sinus through the display screen 3 on the control terminal 5, and adjust the movement of the sub-tube 7 at the head end in real time through the position adjustment operation terminal 4, so that the sub-tube 7 can meet the doctor's idea when moving. In other words, this technical solution is a correction to the aforementioned automatic propulsion, which requires the accuracy of the device of the present invention to enter the venous sinus to prevent harm to the patient.

[0048] For easy operation, the display screen 3 and the position adjustment operation terminal 4 on the control terminal 5 are respectively located on one side of the control terminal 5. The control terminal 5 is also provided with a handheld portion, which is located on the other side of the control terminal 5.

[0049] The present invention uses microelectronic technology to divide the sheath into multiple sub-tubes that are electromagnetically connected to each other. The position of the multiple sub-tubes is automatically adjusted according to the direction of the coronary sinus through the front-end camera, so that the shape of the sheath is consistent with the direction of the coronary sinus, so that the coronary sinus can be entered and the electrode can be delivered at one time, thereby reducing the operation time and improving the success rate of the operation.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
