Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a heart repair filler. Background Art

[0002] In medical fields such as minimally invasive surgery for tissue injection filling, the key to treatment is to use a suitable injection device or filling system to inject a specific amount or volume of injectable (including filler) into the target area or specific location (including injection depth) of the tissue to be treated or repaired.

[0003] In the process of filling the gel in the existing heart repair filler, one end of the filling tube is placed on the surface of the part of the heart to be filled, and then the heart is repaired and filled.

[0004] However, due to the different sizes of the cardiac lesion tissues to be repaired or filled in the target population or patients, the surgeon needs to fine-tune the position of one end of the filling tube against the surface of the area to be filled according to the size and shape of the filling range, so as to ensure the integrity of the filling of the cardiac lesion, which greatly increases the workload of the surgeon; and one end of the filling tube is on the surface of the heart. As the heart keeps beating, the gel inside the filling tube may not be able to be stably filled into the cardiac lesion, which may cause the filler to flow into the surface of other tissues, thereby affecting the smooth progress of the operation, resulting in a prolongation of the operation, and posing a risk to the life safety of the target population or patients.

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The embodiment of the present application provides a heart repair filler, which solves the problem of heavy reliance on surgical personnel to manually adjust the filling position of the filling tube, thereby achieving the purpose of accurately, completely and efficiently filling and repairing heart tissue.

[0052] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0053] The heart repair filler is provided with a guide bending adjustment handle on the outer surface of the guide tube to roughly adjust the direction and angle of the filling tube when entering. At the same time, a filling range adjustment component, a lighting lamp and a camera are provided. The lighting lamp is used to illuminate the position of the heart to be repaired, so that medical staff can observe the patient's chest environment. The camera is used to observe the lesion range of the patient's heart, so as to adjust the size of one end of the rubber tube according to the lesion range. The driving motor in the filling range adjustment component is used to drive the threaded barrel to rotate, so that the threaded ring moves, and the diameter of the rubber tube is correspondingly reduced or increased when sliding inward or outward. The diameter of the rubber tube is adjusted according to the observed damage range of the patient's heart, so as to ensure the integrity of the filling of the patient's heart.

[0054] In addition, by setting up a pressure balancing component, the pressure difference inside and outside the rubber tube is balanced to avoid damage to the heart when the filling tube is pulled out; by setting up a synchronous motion component, in coordination with the filling range adjustment component, the rubber tube can move synchronously with the beating heart, thereby ensuring that the gel inside the filling tube can be stably filled into the heart lesion and reducing the gel from flowing into the surface of other tissues, allowing the operation to proceed smoothly and protecting the patient's life; by setting up a pushing component, the position of the filling tube can be controlled more accurately and smoothly to ensure that it reaches the site that needs to be repaired accurately and slowly, thereby improving the safety of the operation.

[0055] In order to better understand the above technical solution, Figure 1-10 And specific implementation methods are used to describe the above technical solutions in detail.

[0056] Embodiment 1

[0057] This embodiment proposes a heart repair filler, such as Figure 1-2 As shown, it includes: a pilot pipe 1, a filling pipe 3, and a filling range adjustment component 5.

[0058] The filling tube 3 is built into the lumen of the pilot tube 1 and is slidably connected to the inner wall of the pilot tube 1. The filling range adjustment component 5 is arranged at one end of the filling tube 3, and the filling range adjustment component 5 includes a rubber tube 501, and the rubber tube 501 has strong compressibility and stretchability. By adjusting the diameter of the rubber tube 501, the injection amount of the injection (including the filler) can be controlled, thereby controlling the filling range of each injection of the filler.

[0059] In this embodiment, in order to ensure the accuracy of the filling range control as much as possible, the filling range adjustment component 5 is arranged at the front end of the filling tube 3 extending toward the patient's area to be filled.

[0060] Further, in order to ensure that when the filling range adjustment component 5 is arranged at one end of the filling tube 3, the diameter of the rubber tube 501 can be controlled more conveniently and stably, a preferred implementation method is as follows: Figure 3-4 As shown, a fixed cylinder 502 is fixedly installed on the outer surface of the filling tube 3, and the outer wall of the fixed cylinder 502 is slidably connected to the inner wall of the guide tube 1. At the same time, the inner wall of the fixed cylinder 502 is rotatably connected to a rotating gear ring 510, and the inner wall of the rotating gear ring 510 is meshingly connected to a driving gear 503, and a driving shaft is fixedly installed inside the driving gear 503. A side card cover 511 is fixedly installed on the outer end surface of the fixed cylinder 502, and a driving motor 504 is fixedly installed inside the side card cover 511, and the output end of the driving motor 504 is fixedly connected to the driving shaft.

[0061] A threaded cylinder 505 is fixedly installed on one end surface of the rotating gear ring 510, and the inner side surface of the threaded cylinder 505 is threadedly connected to the outer side surface of the threaded ring 506, and a plurality of guide pillars 512 are slidably penetrated and connected inside the threaded ring 506, and one end of the guide pillar 512 is fixedly installed on the inner side wall of the fixed cylinder 502. A plurality of hinge seats 513 are arranged in a circular array on one end surface of the threaded ring 506, and the inner side of the hinge seat 513 is rotatably connected to one end of the adjustment rod 507, and the other end of the adjustment rod 507 is rotatably connected to the adjustment plate 508 through the movable seat, and the adjustment plate 508 is fixedly installed on the outer surface of the rubber tube 501, and the inner side of the movable seat is rotatably connected to the rotating shaft, and the outer surface of the rotating shaft is rotatably connected to the adjusting rod 507, and both ends of the rotating shaft are rotatably connected to the telescopic plates 509, and the telescopic plates 509 are fixedly installed on the inner side wall of the fixed cylinder 502.

[0062] When it is necessary to adjust the diameter of the rubber tube 501 and thus control the size of the filling range, the driving motor 504 rotates, and the fixed tube 502 moves along the guide column 512 through the meshing cooperation of the driving gear 503, the threaded tube 505, and the threaded ring 506. Thus, by pulling the adjusting rod 507 and cooperating with the telescopic plate 509, different pressures are applied to the adjusting plate 508, thereby controlling the diameter of the rubber tube 501 to change the size of the filling range.

[0063] In one embodiment, in order to ensure that the heart repair filler proposed in the above embodiment can freely adjust the angle, so as to approach the patient's area to be repaired at the most appropriate angle and position, a preferred method is that the above heart repair filler also includes a bending adjustment handle, which is used to adjust the filling angle of the heart repair filler during filling.

[0064] More preferably, there are two bending adjustment handles for adjusting the bending degree at different positions. Specifically, the outer surface of the pilot tube 1 is provided with a pilot bending adjustment handle 2, and the filling tube 3 is connected to a secondary bending adjustment handle 4. Figure 1-2Preferably, the bending adjustment handle is an adjustable bending sheath tube structure. The adjustable bending sheath tube structure has an adjustable bending function, and can reach the expected position quickly and reliably through free bending at the far end, which is convenient and quick.

[0065] Embodiment 2

[0066] In order to facilitate the visualization of the process of the heart repair filler in the above embodiment penetrating into the heart surface of the patient's chest cavity, and also to facilitate observation by medical staff, a heart repair filler proposed in this embodiment, based on the above embodiment 1, proposes a preferred method as follows: Figure 5 As shown, an annular placement groove is provided on the side surface of the guide tube 1, and a plurality of cameras 12 are arranged inside the annular placement groove, and the cameras 12 are electrically connected to an external display. When the guide tube 1 moves, the internal cameras 12 are driven to move synchronously, and the environment inside the patient's chest cavity can be observed through the cameras 12.

[0067] Preferably, in order to make the vision clearer, multiple lighting lamps 8 are arranged on both sides of the plurality of cameras 12. The multiple lighting lamps 8 are evenly distributed on both sides of the camera 12 to illuminate the environment inside the patient's chest cavity. The arrangement of the lighting lamps 8 can enhance the light during the penetration of the heart repair filler, and improve the vision and clarity.

[0068] More preferably, in order to effectively protect the camera 12 and the lighting lamp 8, a transparent convex cover 9 is threadedly connected to the inner part of the annular placement groove, and the transparent convex cover 9 will effectively protect the camera 12 and the lighting lamp 8 inside.

[0069] In addition, in order to prevent tissue fluid and the like from adhering to the surface of the transparent convex cover 9 and affecting the line of sight, micro vibrators 10 are provided on both sides of the inner wall of the transparent convex cover 9. The micro vibrators 10 drive the transparent convex cover 9 to vibrate, thereby removing the tissue fluid on the surface of the transparent convex cover 9, ensuring that the camera 12 can clearly observe the internal environment, thereby improving the efficiency of the operation.

[0070] Embodiment 3

[0071] In order to balance the pressure difference between the inside and outside of the rubber tube 501 after the filling material is discharged, a heart repair filling device proposed in this embodiment, based on any of the above embodiments, proposes a preferred method as follows: Figure 6As shown, the cardiac repair filler further includes a pressure balance component 11. The pressure balance component 11 includes: a first row of pressure holes 1111 are opened on both sides of the rubber tube 501, and second row of pressure holes 1112 are opened on both sides of the inner wall of the first row of pressure holes 1111, and one end of the second row of pressure holes 1112 penetrates the rubber tube 501 and is located on the surface of the rubber tube 501. In addition, a connecting plate is fixedly installed on both sides of the rubber tube 501, and a micro electric push rod 1113 is arranged on the side surface of the connecting plate, and a blocking block 1114 is fixedly installed on one end of the micro electric push rod 1113, and the blocking block 1114 is slidably connected to the inside of the first row of pressure holes 1111, and is connected to the output shaft of the micro electric push rod 1113.

[0072] After the gel is discharged, a small negative pressure is formed inside the rubber tube 501. At this time, the blocking block 1114 is driven to move by starting the micro electric push rod 1113. The blocking block 1114 slides outward inside the first row of pressure holes 1111, and the external air enters the interior through the second row of pressure holes 1112, thereby balancing the internal and external pressures and avoiding damage to the heart caused by pulling the filling tube 3 outward.

[0073] Embodiment 4

[0074] The heart repair filler proposed in this embodiment, based on any of the above embodiments, further includes: a plurality of groups of synchronous motion components 6 arranged in a circular array are arranged inside the filling tube 3. Figure 7-8 .

[0075] Each synchronous motion component 6 includes: a support member 601 arranged on the outer surface of the rubber tube 501, and the interiors of several support members 601 are rotatably connected with a first air pipe 602, the first air pipe 602 is fixedly installed inside the guide tube 1, one end of the first air pipe 602 is fixedly installed with an adsorption cover 603, the other end of several first air pipes 602 is fixedly installed on the same connecting air ring 604, one end of the connecting air ring 604 is fixedly installed with an air nozzle 605, the air nozzle 605 penetrates the surface of the guide tube 1 and extends to the outside of the guide tube 1.

[0076] The synchronous motion component 6 also includes a guide column 606 fixedly installed inside the filling tube 3, the outer surface of the guide column 606 is slidably connected with an ejection ring 607, and a filling needle 608 is fixedly installed in a ring array on one side surface of the ejection ring 607. A first slide groove is opened on the inner wall of the filling tube 3, and a guide block 610 is fixedly installed on the side surface of the ejection ring 607. A return spring 609 is fixedly installed on one side surface of the guide block 610, and one end of the return spring 609 is fixedly installed on the inner wall of the first slide groove.

[0077] When the rubber tube 501 is in close contact with the surface of the heart, the adsorption cover 603 rotates and is in close contact with the surface of the heart as the rubber tube 501 moves, and is connected to the air nozzle 605 through an external air pump, so that a negative pressure is formed inside the adsorption cover 603, and the rubber tube 501 is connected to the heart. At the same time, in the process of inputting gel, the gel will squeeze the ejection ring 607 under the guidance of the guide column 606, so that the ejection ring 607 drives the filling needle 608 on one side to insert into the tissue, and the gel will continue to flow inward through the guide column 606, thereby filling the heart tissue. After the filling is completed, the ejection ring 607 drives the guide block 610 to slide inside the first slide groove through the reset force of the reset spring 609, so that the ejection ring 607 resets and slides and the filling needle 608 is separated from the tissue.

[0078] The connection between the adsorption cover 603 and the filling needle 608 allows the rubber tube 501 to move synchronously with the beating heart, thereby ensuring that the gel inside the filling tube 3 can be stably filled into the heart lesion, reducing the gel from flowing onto the surface of other tissues, allowing the operation to proceed smoothly and ensuring the patient's life safety.

[0079] Embodiment 5

[0080] The heart repair filler proposed in this embodiment, based on any of the above embodiments, further comprises: a pushing component 7. Figure 9-10 The push assembly 7 is arranged on the guide tube 1, and the filling tube 3 can be pushed forward slowly and steadily by the push assembly 7, so as to achieve the purpose of safely and steadily approaching the patient's filling area. Specifically, the push assembly 7 includes: a support part 706, the support part 706 is fixedly installed inside the guide tube 1, and the filling tube 3 is slidably connected inside the support part 706. When the filling tube 3 slides inside the support part 706, it is mainly realized in the following ways:

[0081] A second slide groove is provided on the upper and lower sides of the support portion 706, and a driven tooth plate 701 is fixedly installed on the upper and lower sides of the outer surface of the filling tube 3. The surface of the driven tooth plate 701 is meshed with a rotating gear 702, and a transmission shaft 703 is fixedly installed inside the rotating gear 702. Positioning plates are rotatably connected to the outer surface of the transmission shaft 703 on both sides, and the positioning plates are fixedly installed on the inner wall of the guide tube 1. The side surface of the guide tube 1 is rotatably connected to a rotating rod 707, and the rotating rod 707 and the outer surface of the upper transmission shaft 703 are fixedly installed with transmission gears 704, and the transmission gears 704 on the upper and lower sides are meshed with each other. Pulleys are fixedly installed on the outer surface of the rotating rod 707 and the lower transmission shaft 703, and belts are overlapped on the outer surfaces of the two pulleys.

[0082] A protective shell 708 is fixedly mounted on the outer surface of the pilot tube 1, and a rotating rod 707 is rotatably connected to the surface of the protective shell 708. A driving handle 705 is fixedly mounted on one end of the rotating rod 707, and a damping plate is arranged on the surface of the rotating rod 707. The damping plate can reduce the vibration generated when the rotating rod 707 rotates.

[0083] During the filling process, when it is necessary to slowly push the internal filling tube 3, the medical staff slowly rotates the driving handle 705, and the driving handle 705 stably rotates on the surface of the protective shell 708 provided with a damping plate, and the driving handle 705 drives the transmission gear 704 at one end to rotate, and the transmission gear 704 drives the rotating rod 707 to rotate, and the rotating rod 707 drives the transmission shaft 703 below to rotate through the pulley, and the transmission gear 704 below drives the transmission gear 704 above to rotate, and the transmission shafts 703 on the upper and lower sides rotate synchronously in the opposite direction, and the transmission shaft 707 03 drives the rotating gear 702 to rotate, and the rotating rotating gear 702 drives the meshing driven tooth plate 701 below to move, and the driven tooth plate 701 slides inside the second slide groove, and the driven tooth plate 701 drives the filling tube 3 fixedly connected on the surface to slide stably inside the guide tube 1 and the support part 706, reducing the impact force caused by the filling tube 3 on the surface of the heart, greatly reducing the risk of heart tissue rupture and bleeding caused by instantaneous impact force (for example, the impact force caused by medical staff's operating errors, excessive force, etc.), and improving the safety of the operation. At the same time, by slowly and steadily sliding the filling tube 3 until it touches the heart, the operator can control the position of the filling tube 3 more accurately to ensure that it accurately reaches the part that needs to be repaired, thereby improving the effectiveness and safety of the operation.

[0084] The following is a method of using and operating instructions for the heart repair filler proposed in the above embodiment of the present application:

[0085] First, the guide tube 1 is passed through the incision into the patient's chest cavity, and then the guide bending adjustment handle 2 is used to preliminarily adjust the bending degree of the guide tube 1 to reach the surface of the heart;

[0086] The range to be filled is observed through the camera 12, and the rubber tube 501 at one end of the filling tube 3 is slid out of the interior of the pilot tube 1 through the pushing assembly 7, and the curvature of the filling tube 3 is adjusted through the secondary bending adjustment handle 4, so that one end of the filling tube 3 corresponds to the damaged area of ​​the heart more accurately;

[0087] Then, according to the filling range, the driving motor 504 is started to rotate clockwise or counterclockwise, driving the driving gear 503 to rotate, the driving gear 503 drives the meshing rotating gear ring 510 to rotate, the rotating gear ring 510 drives the threaded tube 505 to rotate, the threaded tube 505 rotates so that the threaded ring 506 slides stably on the outer surface of the guide column 512, so that the threaded ring 506 moves parallel, the threaded ring 506 drives the adjusting rod 507 on one side to move through the hinge seat 513, the adjusting rod 507 drives the adjusting plate 508 to move through the rotating shaft, so that the internal rubber tube 501 expands outward or contracts inward, the adjusting plate 508 drives the rotating shaft to move, and the rotating shaft moves vertically under the guidance of the telescopic plate 509, so as to ensure the stability of the adjusting plate 508 during movement, and the size of one end of the rubber tube 501 is adjusted according to the observed damaged range of the patient's heart, so as to ensure the integrity of the filling of the patient's heart, and there is no need to move the filling tube 3 continuously to fill the lesion range, thereby reducing the workload of medical staff.

[0088] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0089] 1. A heart repair filler proposed in the present invention can adjust the size of one end of the rubber tube according to the damaged range of the patient's heart by setting a filling range adjustment component, thereby ensuring complete and accurate filling of the patient's heart. Medical staff do not need to manually move the filling tube constantly to fill the diseased range, which not only ensures the accuracy and completeness of the filling range, but also reduces the workload of medical staff.

[0090] 2. The heart repair filler proposed in the present invention can roughly adjust the initial position, direction, and angle of the filling catheter when it enters by setting a pilot bending adjustment handle and a secondary bending adjustment handle, thereby ensuring that the filling catheter can reach the position to be repaired quickly and accurately.

[0091] 3. The cardiac repair filler proposed in the present invention can illuminate the interior of the tissue to be repaired by arranging a camera and a lighting lamp, so as to facilitate medical staff to observe the patient's chest environment and observe and grasp the scope of the patient's heart lesions; further, a transparent convex cover and a micro vibrator are arranged to protect and optimize the camera and the lighting lamp, which can reduce the influence of tissue fluid on the field of vision during observation, ensure that the camera can clearly observe the internal environment of the tissue to be repaired, and improve the efficiency of the operation.

[0092] 4. The heart repair filler proposed by the present invention can balance the pressure difference between the inside and outside of the rubber tube after the gel is discharged from the filling tube by setting a pressure balance component, thereby avoiding damage to the heart when the filling tube is pulled out.

[0093] 5. A heart repair filler proposed by the present invention cooperates with a filling range adjustment component by setting a synchronous motion component. When one end of the filling range adjustment component is on the surface of the heart, the adsorption cover on the outer surface of the synchronous motion component is synchronously located on the surface of the heart. As one end of the filling range adjustment component moves, the adsorption cover rotates and adheres to the surface of the heart, and then is connected to the air nozzle through an external air pump, so that negative pressure is formed inside the adsorption cover and adsorbed on the surface of the heart. During the filling process, the movement of the gel will squeeze the ejection ring to slide to one side, driving the filling needle at one end to penetrate into the heart tissue. The two connection methods allow the rubber tube to move synchronously with the beating heart, thereby ensuring that the gel inside the filling tube can be stably filled into the heart lesion and reducing the gel from flowing into the surface of other tissues, so that the operation can be carried out smoothly and the patient's life safety can be guaranteed.

[0094] 6. A heart repair filler proposed in the present invention, by providing a pushing assembly, can rotate the driving handle to make the rotating gears on the upper and lower sides rotate synchronously in opposite directions, so that the meshing driven gear plate below drives the internal filling tube to move slowly, and the filling tube can slide stably and slowly inside the guide tube, thereby reducing the impact force of the filling tube on the surface of the heart, and greatly reducing the risk of serious consequences such as heart tissue rupture and bleeding due to instantaneous impact force. At the same time, in the process of slowly contacting the heart, the operator can control the position of the filling tube more accurately to ensure that it accurately reaches the part that needs to be repaired, thereby improving the safety of the operation.
