Description

Technical Field

[0001] The present invention relates to the technical field of magnetic anastomosis devices, and more specifically, to a magnetic anastomosis device for tissue clamping under a digestive endoscope. Background Art

[0002] With the development of medical technology, minimally invasive treatment techniques under a digestive endoscope have gradually become the preferred treatment options for many digestive system diseases. Among them, the technology of using a digestive endoscope to control a magnetic anastomosis device for tissue clamping has shown significant advantages in clinical applications. This technology is particularly suitable for patients who require temporary tissue clamping, such as in the repair of gastrointestinal fistulas, perforation repair, endoscopic gastric bypass surgery, and other situations where it is necessary to temporarily seal or connect gastrointestinal tissues.

[0003] During the process of using a magnetic anastomosis device for temporary tissue clamping, first, it is necessary to select a magnetic anastomosis device of an appropriate size according to the treatment needs of different patients. Then, the magnetic anastomosis device is sent to the target position through a digestive endoscope. After accurately positioning the target tissue with the camera on the endoscope, the adjustment module on the release mechanism can be used to finely adjust the magnetic elements to ensure that they are accurately adsorbed on the target tissue. Then, the magnetic elements are unlocked through the release handle to make them tightly combined with the target tissue.

[0004] Although the technology of using a digestive endoscope to control a magnetic anastomosis device for tissue clamping has made significant progress clinically, there are still some challenges, especially the problem that the position of the magnetic anastomosis device cannot be effectively adjusted after it is placed and clamped. Because in the actual operation process, once the magnetic elements are adsorbed on the target tissue after the magnetic anastomosis device releases the magnetic elements, it is very difficult to adjust the position again. Moreover, most of the magnetic elements are in an integrated circular ring shape, which may cause some areas on the magnetic ring not to be accurately adsorbed at the optimal position, thus affecting the treatment effect of temporary sealing. Therefore, it is necessary to provide a magnetic anastomosis device for tissue clamping under a digestive endoscope. Summary of the Invention

[0005] Aiming at the problem that it is very difficult to adjust the position again once the magnetic elements are adsorbed on the target tissue in the prior art, the purpose of the present invention is to provide a magnetic anastomosis device for tissue clamping under a digestive endoscope.

Second buffer bottom plates are fixedly installed on the outer edge surface of the second engaging ring at positions corresponding to each side linear guide rail frame. A number of sixth magnetic attraction blocks with gradually decreasing magnetic properties are sequentially fixedly installed on the surface of the second buffer bottom plate.

[0015] Optionally, second magnetic attraction blocks are fixedly installed on both side surfaces of the square sleeve block facing the first circular opening and the second circular opening; and the second magnetic attraction blocks on each side are magnetically repulsive to the fifth magnetic attraction blocks and the sixth magnetic attraction blocks at the corresponding circular opening ends. Release module touch tubes are sleeved and installed outside the first wiring block, the first limit buckle, and the second limit buckle.

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] In the above solution, through the adjustment area and the reserved area provided by the circular ring skeleton, during the temporary clamping process, through the rotation setting of the magnetic attraction cover plate mechanism, the configured first magnetic attraction block can be rotated to any position in the adjustment area to interact with the adjustable magnetic attraction block mechanism at the bottom, so that the fourth magnetic attraction block of the adjustable magnetic attraction block mechanism is lifted upward, which is different from the prior art and can temporarily loosen the clamping end at this position. Further adjustment can still be carried out when the upper part of the magnetic circular ring fails to be accurately adsorbed at the optimal position, improving the flexibility and controllability of the magnetic components.

[0021] Through the inner ring magnetic attraction adjustment ring mechanism and the outer ring magnetic attraction adjustment ring mechanism configured on the inner and outer rings of the circular ring skeleton, by using the release module touch tube on the release module to pull the corresponding first clamping ring and second clamping ring, the magnetic blocks with different magnetic forces can be aligned with the square sleeve blocks in sequence, and the position of the whole adjustable magnetic attraction block mechanism can be adjusted by using the different magnetic forces at the head and tail ends, so that the magnetic components can adjust the inner diameter of the adsorption end circular ring according to the actual situation of the patient and the actual situation of the temporary clamping during use, further improving the flexibility and controllability of the magnetic components.

[0022] Magnetic drive can avoid the problems of jamming or overload that may occur in mechanical drive, thereby improving the safety during the temporary clamping process. And the magnetic drive has a fast response time. Different from mechanical drive adjustment, it not only produces a smaller motion effect feedback to improve the comfort of the patient, but also does not require lubrication because it is non-contact, which can reduce the maintenance cost and complexity.

[0023] During the process of the inner ring magnetic attraction adjustment ring mechanism and the outer ring magnetic attraction adjustment ring mechanism cooperating to adjust the position of the adjustable magnetic attraction block mechanism, they can also control the position of the draw plate by pulling the pull wire through the square sleeve block, and can control the draw plate to pull the film upward. When the fourth magnetic attraction block is lifted upward to cancel the clamping state, the tissue at the corresponding end can be pulled, so that the tissue at the clamped end can be finely adjusted again, further improving the flexibility and controllability of the magnetic components.

[0049] As Figures 1 to 10 shown, an embodiment of the present invention provides a magnetic anastomosis device for tissue clamping under a digestive endoscope, including a first magnetic element 1 and a second magnetic element 2, the overall structures of the first magnetic element 1 and the second magnetic element 2 being the same; from top to bottom, it successively includes a magnetic attraction cover plate mechanism 6, a circular ring support mechanism 4, and a secondary fine adjustment mechanism 5.

[0050] The circular ring support mechanism 4 includes a circular ring skeleton 41 for overall support, and a plurality of linear guide rail frames 45 are fixedly connected to the inner wall of the circular ring skeleton 41; an adjustable magnetic attraction block mechanism 7 facing the secondary fine adjustment mechanism 5 is slidably disposed on each linear guide rail frame 45.

[0051] Among them, the adjustable magnetic attraction block mechanism 7 includes a square sleeve block 71 and third magnetic attraction blocks 74 and fourth magnetic attraction blocks 75 located on the upper and lower sides of the square sleeve block 71. The secondary fine adjustment mechanism 5 includes a circular ring tray frame 51 fixedly installed at the bottom of the circular ring skeleton 41 and a thin film 56 corresponding to each adjustable magnetic attraction block mechanism 7 on the circular ring tray frame 51. The third magnetic attraction block 74 is magnetically adsorbed and corresponding to the magnetic pole of the magnetic attraction cover plate mechanism 6, and is used to lift the fourth magnetic attraction block 75 at the corresponding end to loosen the clamping state on this side to adjust the clamped tissue.

[0052] To solve the problem in the prior art that it is very difficult to adjust the position when a magnetic element is adsorbed on a target tissue, the above technical solution is adopted to solve it. The above technical solution mainly includes a first magnetic element 1 and a second magnetic element 2. The overall structures of the first magnetic element 1 and the second magnetic element 2 are the same, but the difference is that one acts on one end and the other end of the tissue to be temporarily clamped. And each element is composed of a magnetic attraction cover plate mechanism 6, a circular ring support mechanism 4, and a secondary fine adjustment mechanism 5. Among them, the circular ring support mechanism 4 plays an overall supporting role, with a magnetic attraction cover plate mechanism 6 movably sleeved on the upper side and a circular ring tray frame 51 fixedly installed at the bottom. Through the effect that the third magnetic attraction block 74 is magnetically adsorbed and corresponding to the magnetic pole of the magnetic attraction cover plate mechanism 6, during use, the fourth magnetic attraction block 75 at the corresponding end can be lifted to loosen the clamping state on this side to adjust the clamped tissue, so as to solve the problem in the prior art that it is very difficult to adjust the position when a magnetic element is adsorbed on a target tissue.

[0053] As Figures 1 to 6 shown, at the center position of the circular ring skeleton 41, a first guide rail circular ring frame 44 is fixedly connected through the support of a linear guide rail frame 45. A second guide rail circular ring frame 48 is fixedly installed on the outer edge surface of the circular ring skeleton 41. The inner circle of the circular ring skeleton 41 is divided into an outer circle and an inner circle by the separation of the first guide rail circular ring frame 44. The outer circle is an adjustment area 42, and the inner circle is a reserved area 43. The linear guide rail frames 45 are uniformly arranged at a certain interval in the adjustment area 42. The opening of the reserved area 43 communicates with the opening at the center position of the circular ring tray frame 51 to serve as a temporary channel in the tissue clamping state.

[0054] As Figures 2 to 4As shown, the entire linear guide rail frame 45 is a support plate structure composed of two groups connected to the inner wall of the adjustment area 42; and first limit notch openings 46 are provided on the support plates thereof. The square sleeve blocks 71 are movably sleeved on the linear guide rail frames 45 on each side; and auxiliary wheels 76 sleeved in the first limit notch openings 46 are movably installed at both ends of the surface of each square sleeve block 71. Insertion rods 73 capable of moving up and down are movably inserted into the surfaces of the square sleeve blocks 71. The third magnetic attraction block 74 is fixedly installed on the upper side of the insertion rod 73; and the magnetic attraction end faces outward. The fourth magnetic attraction block 75 is fixedly installed on the lower side of the insertion rod 73; and the magnetic attraction end faces outward.

[0055] As Figures 3 to 6 shown, the magnetic attraction cover plate mechanism 6 includes a circular ring cover plate 61 movably installed on the upper side of the circular ring skeleton 41. A visible circular ring partition 63 is fixedly installed on the surface of the circular ring cover plate 61. A first wiring block 62 is fixedly installed on the upper circular ring surface of the visible circular ring partition 63. A first magnetic attraction block 64 is fixedly installed on the lower circular ring surface of the visible circular ring partition 63. The overall length of the first magnetic attraction block 64 is the same as the inner diameter of the adjustment area 42; and its magnetic pole is adsorbed and corresponding to the magnetic pole of the third magnetic attraction block 74. First circular openings 47 penetrating the first guide rail circular ring frame 44 and second circular openings 49 penetrating the second guide rail circular ring frame 48 are respectively provided at the head and tail ends of the linear guide rail frame 45.

[0056] Among them, the configured visible circular ring partition 63 and the circular ring cover plate 61 are of an integral structure, specifically manifested as a visible circular ring partition 63 is configured on the surface of the circular ring cover plate 61, which can cooperate with the camera end on the release structure for real-time detection. The first circular opening 47 penetrating the first guide rail circular ring frame 44 and the second circular opening 49 penetrating the second guide rail circular ring frame 48 are specifically opened on the two circular ring frames.

[0057] As Figures 3 to 6 shown, arc guide notch openings 410 are provided on the upper and lower edge surfaces of the first guide rail circular ring frame 44 and the second guide rail circular ring frame 48. An inner ring magnetic attraction adjustment ring mechanism 8 is movably configured inside the first guide rail circular ring frame 44. The inner ring magnetic attraction adjustment ring mechanism 8 includes a first engaging circular ring 81. First limit buckles 82 slidably clamped in the arc guide notch openings 410 of the first guide rail circular ring frame 44 are fixedly installed on the upper and lower edge surfaces of the first engaging circular ring 81. First buffer bottom plates 83 are fixedly installed on the outer edge surface of the first engaging circular ring 81 corresponding to the positions of the linear guide rail frames 45 on each side. A number of fifth magnetic attraction blocks 84 with gradually decreasing magnetic properties are fixedly installed in sequence on the surface of the first buffer bottom plate 83.

[0058] As Figures 3 to 8As shown, an outer ring magnetic attraction adjustment ring mechanism 9 is movably arranged on the second guide rail ring frame 48. The outer ring magnetic attraction adjustment ring mechanism 9 includes a second engaging ring 91. Second limit buckles 92 that are slidably clamped in the arc guide notches 410 of the second guide rail ring frame 48 are fixedly installed on the upper and lower edge surfaces of the second engaging ring 91. Second buffer bottom plates 93 are fixedly installed on the outer edge surface of the second engaging ring 91 corresponding to the positions of each side linear guide rail frame 45. A number of sixth magnetic attraction blocks 94 with gradually decreasing magnetic properties are fixedly installed on the surface of the second buffer bottom plates 93 in sequence.

[0059] As Figures 3 to 8 shown, second magnetic attraction blocks 72 are fixedly installed on both side surfaces of the square sleeve block 71 facing the first round opening 47 and the second round opening 49; and the second magnetic attraction blocks 72 on each side are magnetically repulsive to the fifth magnetic attraction blocks 84 and the sixth magnetic attraction blocks 94 at the corresponding round opening ends. Release module touch tubes 3 are sleeved and installed outside the first wiring block 62, the first limit buckle 82, and the second limit buckle 92.

[0060] Among them, the configured release module touch tube 3 is a touch tube structure installed on the release module in the prior art. The release module is a structure for releasing magnetic elements in the prior art. It generally includes a handle for a doctor to control the release of magnetic elements, an adjustment module for ensuring that the magnetic elements remain fixed during transportation, and an indicator for displaying the state of the magnetic elements. The touch tube is a tubular structure connected to the release end. It is an overall slender flexible tube used to send magnetic elements into the digestive tract and is used in conjunction with a push rod, all of which are conventional configurations in the prior art.

[0061] The specific working state of its adjustable magnetic attraction block mechanism 7 is:

[0062] Pre-adjustment stage: According to requirements, the release module touch tube 3 set on the first limit convex buckle 82 and the second limit convex buckle 92 can be used to pull the inner ring magnetic attraction adjustment ring mechanism 8 and the outer ring magnetic attraction adjustment ring mechanism 9 respectively. Since the magnetic force of the fifth magnetic attraction block 84 on the outer ring of the first engagement ring 81 that is movably clamped in the first guide rail ring frame 44 gradually weakens, and the magnetic force of the second engagement ring 91 that is movably clamped in the second guide rail ring frame 48 also gradually weakens, and both are aligned with the second magnetic attraction block 72 on the square sleeve block 71 through the first round opening 47 and the second round opening 49 on the corresponding side. Therefore, only the first engagement ring 81 and the second engagement ring 91 need to be adjusted separately. By sliding the first limit convex buckle 82 and the second limit convex buckle 91 in the arc guide groove 410 to change their respective positions, the fifth magnetic attraction block 84 and the sixth magnetic attraction block 94 with different magnetic forces can be aligned with the second magnetic attraction blocks 72 on the front and back sides of the square sleeve block 71, so that the square sleeve block 71 changes its current position. For example, if the magnetic force of the fifth magnetic attraction block 84 is stronger than that of the sixth magnetic attraction block 94, the square sleeve block 71 will move towards the outer end of the ring frame 41 along the linear guide rail frame 45, and vice versa, it will move towards the inner end of the ring frame 41 to change the position of the square sleeve block 71. The change in the position of the square sleeve block 71 can synchronously adjust the position of each fourth magnetic attraction block 75 to change the inner diameter of the magnetic attraction end of the magnetic component;

[0063] Secondary fine-tuning stage: After controlling the release of the first magnetic component 1 and the second magnetic component 2 into the digestive tract through the release module touch tube 3, when they enter the designated position, several groups of fourth magnetic attraction blocks 75 on the two components will adsorb and fit to temporarily clamp this position. When it is necessary to perform secondary fine-tuning on a certain area of the temporarily clamped end, only need to pull the release module touch tube 3 set on the first connection block 62, and control the ring cover plate 61 movably clamped on the upper side of the ring frame 41 to rotate through the release module touch tube 3. During the rotation of the ring cover plate 61, the first magnetic attraction block 64 on its bottom surface will also rotate synchronously. During the rotation around the adjustment area 42, since the first magnetic attraction block 64 and the third magnetic attraction block 74 on the upper side of the insertion rod 73 of the square sleeve block 71 attract each other, in the state of being vertically aligned with the third magnetic attraction block 74 on the corresponding side, the first magnetic attraction block 64 will adsorb the third magnetic attraction block 74 at this position. And the insertion rod 73 is movably installed on the square sleeve block 71, and the upward lifting of the third magnetic attraction block 74 will drive the synchronous upward movement of the fourth magnetic attraction block 75, so that the fourth magnetic attraction blocks 75 in the adsorbed state on the first magnetic component 1 and the second magnetic component 2 will separate, thus canceling the clamping state at this position;

[0064] Among them, since the first magnetic element 1 and the second magnetic element 2 are extended into the patient's interior through the release module contact tube 3 on the release module, and the release module is provided with a corresponding camera end to provide real-time feedback of the internal situation, and with the help of the camera end and the visible circular ring partition 63 of the circular ring cover 61, the internal situation of the circular ring frame 41 can also be observed, so as to facilitate the control of the fourth magnetic suction block 75 on the corresponding side to lift up to cancel the clamping state of the corresponding side.

[0065] like Figures 2 to 10 As shown, the ring tray frame 51 is a hollow cylindrical structure with an open upper side; and a first square slot 52 is provided on the bottom surface of the cylinder at a position corresponding to the linear guide frame 45 on each side; a connected second square slot 53 is provided on the inner end cylindrical side surface corresponding to the first square slot 52 on each side, and the first square slot 52 and the second square slot 53 are an L-shaped opening shape along the cylindrical end of the ring tray frame 51; and a second limiting slot 54 is provided on the inner wall of each first square slot 52 and the second square slot 53, and a limiting baffle 58 is fixedly connected at the intersection of the first square slot 52 and the second square slot 53.

[0066] like Figures 2 to 10 As shown, a spring winding drum 55 is fixedly installed on one end of the first square slot 52 close to the side wall of the ring tray frame 51, and the spring winding drum 55 is a winding drum structure with a built-in return spring; and a film 56 that is slidably sleeved in the second limiting slot 54 is fixedly connected to its winding end, and the film 56 is arranged at the bottom of the ring tray frame 51 through a limiting baffle 58 on the corresponding side.

[0067] like Figures 2 to 10 As shown, a pull plate 57 is fixedly installed on one end of the film 56 away from the spring winding drum 55, and the pull plate 57 is also slidably stuck in the second limiting groove 54 on the corresponding side, and the upper side of the second square groove 53 is fixedly connected with an extended side plate 59, and a threading opening 510 is opened in the middle position of the surface of the extended side plate 59, and the upper surface of the pull plate 57 is fixedly connected with a pull wire 511 passing through the threading opening 510; and the pull wire 511 passing through each side is fixedly connected to the square sleeve block 71 on the corresponding side.

[0068] Among them, the fourth magnetic attraction block 75 of the adjustable magnetic attraction block mechanism 7 at the corresponding position on the circular ring skeleton 41 is lifted upward. After canceling the clamping state on the corresponding side, the thin film 56 in the secondary fine-tuning mechanism 5 can also be pulled by the adjustable magnetic attraction block mechanism 7 for secondary fine-tuning. The specific steps are as follows: First, the first magnetic attraction block 64 at the bottom of the circular ring cover plate 61 is aligned with the fourth magnetic attraction block 75 on the corresponding side. After lifting it, the relative positions of the inner ring magnetic attraction adjustment ring mechanism 8 and the outer ring magnetic attraction adjustment ring mechanism 9 can be adjusted again through the release module touch tube 3 configured on the first limit buckle 82 and the second limit buckle 92, so that the square sleeve block 71 closely adheres to the outermost inner wall of the circular ring skeleton 41. The other end of the pull wire 511 is connected to the square sleeve block 71. During the outward expansion of the square sleeve block 71, it will pull the thin film 56 at the bottom of the pull plate 57, causing the thin film 56 to move upward along the second limit notch 54 on the first square notch 52 and the second square notch 53. The bottom of the thin film 56 is in contact with the tissue layer of the patient. Therefore, when the thin film 56 is pulled upward, the tissue layer on the corresponding side will also be pulled, causing the tissue layer at this position to be secondarily fine-tuned;

[0069] Among them, the limit baffle 58 configured at the first square notch 52 and the second square notch 53 is used to limit the thin film 56 outward, so that the thin film 56 can move at the outermost edge position at the bottom of the circular ring tray 51 to pull the tissue layer at this position well. The configured pull plate 57 is specifically slidably clamped in the second limit notch 54 on the vertical side.

[0070] The working process of the technical solution of the present invention is as follows:

[0071] First, the release module touch tube 3 is used to pull the first limit buckle 82 and the second limit buckle 92 on the inner ring magnetic attraction adjustment ring mechanism 8 and the outer ring magnetic attraction adjustment ring mechanism 9, so that the first engaging circular ring 81 and the second engaging circular ring 92 rotate correspondingly, changing the positions of the fifth magnetic attraction block 84 and the sixth magnetic attraction block 94 at one end of the second magnetic attraction block 72 on the surface facing the square sleeve block 71. According to the corresponding magnetic force, the position of the square sleeve block 71 is adjusted, the position of the fourth magnetic attraction block 75 is changed to change the inner diameter of the entire magnetic component. Further, the first magnetic attraction block 64 on the rotating circular ring cover plate 61 can be used to adsorb the third magnetic attraction block 74 to release the fourth magnetic attraction block 75 on the corresponding side, and cooperate with the square sleeve block 71 to pull the pull plate 57 upward, so that the thin film 56 in the secondary fine-tuning mechanism 5 pulls the tissue layer, causing the tissue layer at this position to be secondarily fine-tuned.
