Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an intestinal anti-absorber implantation device. Background Art

[0002] Intestinal anti-absorbers can be clinically used to help control metabolic diseases such as obesity, diabetes, and non-alcoholic fatty liver, and have good application prospects.

[0003] See Figure 1 As shown, the working principle of the intestinal anti-absorber 100 is as follows: The intestinal anti-absorber 100 includes a stent body 110 and a membrane tube 120 connected to one end of the stent body 110. The intestinal anti-absorber 100 is implanted into the human body through an implantation device, so that the membrane tube 120 is implanted into the duodenum to isolate chyme. Thus, after implantation, the food from the stomach passes through the cavity of the membrane tube 120, while bile and pancreatic juice are isolated outside the membrane tube 120, causing the bile, pancreatic juice and food to "diverge", blocking the digestion and absorption of food in the intestine, and adjusting the secretion of digestive enzymes, thereby playing a role in regulating blood sugar, blood lipids and controlling body weight. However, the existing intestinal anti-absorber implantation device pushes out the intestinal anti-absorber by relative sliding between the tubes. Due to the elastic restoring force, the intestinal anti-absorber 100 will quickly unfold itself. The process of the intestinal anti-absorber 100 unfolding itself is uncontrollable, and the huge impact force generated by the rapid unfolding easily causes the intestinal anti-absorber 100 to deviate too much, resulting in an unsatisfactory release position.

[0004] Therefore, it is necessary to provide a new intestinal anti-absorber implantation device. Summary of the Invention

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present invention is to provide an intestinal anti-absorber implantation device that can control the process of the intestinal anti-absorber unfolding itself and avoid the unsatisfactory release position caused by excessive deviation of the intestinal anti-absorber.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: An intestinal anti-absorption device placement device includes an inner tube, an outer tube sleeved outside the inner tube, a middle tube disposed between the inner tube and the outer tube and connected to the inner tube, and a stopper. One end of the inner tube is provided with a guiding head. The stopper is connected to one end of the middle tube close to the guiding head. An accommodation cavity is provided in the inner cavity of the outer tube between the stopper and the guiding head. The outer tube and the inner tube can slide relative to each other axially. The intestinal anti-absorption device placement device further includes a binding wire. The binding wire is tied to the folded intestinal anti-absorption device through a slipping knot. One end of the binding wire is fixed to the middle tube, and the other end of the binding wire passes out of the intestinal anti-absorption device placement device. When pulling the end of the binding wire that passes out of the intestinal anti-absorption device placement device, the binding wire tied to the intestinal anti-absorption device will gradually disengage along the axial direction of the intestinal anti-absorption device until the binding wire completely disengages from the intestinal anti-absorption device.

[0007] Further, the intestinal anti-absorption device placement device further includes a first handle fixedly connected to the inner tube and the middle tube, and a second handle fixedly connected to the outer tube.

[0008] Further, the end of the binding wire for passing out of the intestinal anti-absorption device placement device finally passes out through a first through-hole on the first handle.

[0009] Further, a first window is opened on the middle tube near the accommodation cavity. The end of the binding wire for passing out of the intestinal anti-absorption device placement device passes through the gap between the middle tube and the inner tube through the first window until it passes out through the first through-hole.

[0010] Further, a guiding member corresponding to the end of the inner tube is installed on the first handle. A first through-hole communicating with the inner cavity of the inner tube and the first through-hole is opened on the guiding member. The inner tube is inserted and fixed in the first through-hole of the guiding member. A second through-hole is also opened on the guiding member. The end of the binding wire for passing out of the intestinal anti-absorption device placement device sequentially passes through the second through-hole and the first through-hole.

[0011] Further, a first window is opened on the middle tube near the accommodation cavity. Two inner tubes are arranged side by side. Both inner tubes pass through the middle tube. A second window is opened on one of the inner tubes near the first window on the middle tube. The end of the binding wire for passing out of the intestinal anti-absorption device placement device sequentially passes through the first window, the second window, and the inside of the inner tube provided with the second window until it passes out through the first through-hole.

[0012] Further, a guide member corresponding to the end of the inner tube is installed on the first handle. Two first through holes are formed in the guide member, and the first through holes communicate with the first through ports. The two inner tubes are respectively inserted and fixed in the two first through holes of the guide member, and one end of the binding wire for passing out of the intestinal anti-absorbing device is sequentially passed through one of the first through holes and the first through port.

[0013] Further, the intestinal anti-absorbing device further includes a fixing member. The fixing member is sleeved and fixed on the middle tube, and one end of the binding wire for being fixed on the middle tube is pressed on the middle tube.

[0014] Further, the intestinal anti-absorbing device further includes a pull ring. The pull ring is fixed to one end of the binding wire passing out of the intestinal anti-absorbing device.

[0015] Further, the elastic intestinal anti-absorbing device can be folded and compressed and can automatically unfold when the restraint is removed.

[0016] The beneficial effects of the present invention are as follows: The intestinal anti-absorbing device provided by the present invention further includes a binding wire. The binding wire is tied to the folded intestinal anti-absorbing device through a slip knot. One end of the binding wire is fixed on the middle tube, and the other end of the binding wire passes out of the intestinal anti-absorbing device. When pulling the end of the binding wire passing out of the intestinal anti-absorbing device, the binding wire tied to the intestinal anti-absorbing device will gradually disengage along the axial direction of the intestinal anti-absorbing device until the binding wire completely disengages from the intestinal anti-absorbing device, and the intestinal anti-absorbing device automatically unfolds. Therefore, in the intestinal anti-absorbing device provided by the embodiment of the present invention, by moving the outer tube relative to the inner tube, the accommodating cavity can be opened. When the accommodating cavity is opened, pulling the binding wire can make the binding wire tied to the intestinal anti-absorbing device gradually disengage, so that the intestinal anti-absorbing device will be controlled by the binding wire and gradually unfold automatically. Compared with the prior art, the process of the automatic unfolding of the intestinal anti-absorbing device can be controlled, and it is avoided that the intestinal anti-absorbing device deviates too much during the unfolding process, resulting in an unsatisfactory release position of the intestinal anti-absorbing device.

Detailed implementation manners

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] It should be noted that when an element is referred to as being "connected to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the phrases "in one embodiment", "in some embodiments" or "in some of these embodiments" appearing throughout the specification do not all refer to the same embodiment. Additionally, in one or more embodiments, the specific features, structures, or characteristics may be combined in any suitable manner.

[0039] Please refer to Figure 2 and Figure 3As shown in the figure, a device for implanting an intestinal anti-absorber provided by an embodiment of the present invention will be described. The device for implanting an intestinal anti-absorber provided by an embodiment of the present invention is used to release the intestinal anti-absorber 100 into the human body. The device for implanting an intestinal anti-absorber includes an inner tube 1, an outer tube 2 sleeved outside the inner tube 1, a middle tube 3 between the inner tube 1 and the outer tube 2 and connected to the inner tube 1, and a stop block 4. One end of the inner tube 1 is provided with a guiding head 11 located outside the outer tube 2. The stop block 4 is connected to one end of the middle tube 3 close to the guiding head 11. The stop block 4 is used to block one corresponding end of the intestinal anti-absorber 100. An accommodation cavity 5 is provided in the inner cavity of the outer tube 2 between the stop block 4 and the guiding head 11. The accommodation cavity 5 is used to accommodate the intestinal anti-absorber 100 in a folded state. The outer tube 2 and the inner tube 1 can slide relative to each other along the axial direction. When the outer tube 2 moves relative to the inner tube 1 until the outer tube 2 abuts against the guiding head 11, the accommodation cavity 5 is closed; and when the outer tube 2 moves relative to the inner tube 1 until it disengages from the guiding head 11, the accommodation cavity 5 is opened. The device for implanting an intestinal anti-absorber further includes a tying wire 8. Refer to Figure 5 As shown in the figure, the tying wire 8 is tied to the intestinal anti-absorber 100 in a folded state through a slipping knot. One end of the tying wire 8 is fixed to the middle tube 3, and the other end of the tying wire 8 passes out of the device for implanting an intestinal anti-absorber. When pulling the end of the tying wire 8 that passes out of the device for implanting an intestinal anti-absorber, the tying wire 8 tied to the intestinal anti-absorber 100 will gradually disengage along the axial direction of the intestinal anti-absorber 100 until the tying wire 8 completely disengages from the intestinal anti-absorber 100, and the intestinal anti-absorber 100 unfolds itself. Therefore, for the device for implanting an intestinal anti-absorber provided by an embodiment of the present invention, by moving the outer tube 2 relative to the inner tube 1, the accommodation cavity 5 can be opened. When the accommodation cavity 5 is opened, pulling the tying wire 8 can make the tying wire 8 tied to the intestinal anti-absorber 100 gradually disengage, so that the intestinal anti-absorber 100 will be controlled by the tying wire 8 and gradually unfold itself. Compared with the prior art, the process of the intestinal anti-absorber 100 unfolding itself can be controlled, avoiding excessive deviation of the intestinal anti-absorber 100 during the unfolding process, resulting in an unsatisfactory release position of the intestinal anti-absorber 100.

[0040] In some embodiments, the elastic intestinal anti-absorber 100 can be folded and compressed and unfold itself when the restraint is removed. As Figure 1 shown in the figure, after the intestinal anti-absorber 100 is unfolded, the stent body 110 thereof is restricted at the pylorus 220. The main function of the stent body 110 is to fix the position of the membrane tube 120, so that the membrane tube 120 is placed and stays in the duodenum 210.

[0041] In some of these embodiments, the stent body 110 is a rhombic structure woven from elastic wires, which enables the stent body 110 to be compressed or expanded in the transverse and longitudinal directions, has good elastic deformation ability, and facilitates the compression of the stent body 110 into the accommodation cavity 5 of the intestinal anti-absorption device. In some of these embodiments, the elastic wires can be metal wires, polymer material wires, or biodegradable material wires.

[0042] As Figure 2 shown, in some of these embodiments, the guide head 11 is a conical structure, which is conducive to passing through the inner wall of the tissue. Additionally, the guide head 11 is made of a soft material and will not cause damage to the inner wall of the tissue.

[0043] As Figure 3 shown, in some of these embodiments, the inner tube 1 is a hollow tubular structure. Thus, during use, the intestinal anti-absorption device can be guided to a designated position by threading a guide wire through the inner tube 1. More precisely, before using the intestinal anti-absorption device, after the guide wire is inserted into the human intestine through the endoscopic channel, the guide wire is kept in its original position, the endoscope is withdrawn, and then the intestinal anti-absorption device provided by the embodiments of the present invention is guided into the duodenum through the guide wire. Subsequently, the intestinal anti-absorption device is operated to release the intestinal anti-absorption device 100.

[0044] As Figure 4 shown, in some of these embodiments, the stopper 4 includes a boss 41 and a plug 42 provided at one end of the boss 41. Also referring to Figure 3 , the plug 42 is inserted and fixed in the middle tube 3, and an abutting end face 411 is provided at one end of the boss 41 exposed outside the middle tube 3. Thus, when the outer tube 2 slides relative to the inner tube 1 to open the accommodation cavity 5, due to the blocking of the intestinal anti-absorption device 100 by the abutting end face 411, the intestinal anti-absorption device 100 is not easily moved along with the outer tube 2 and thus slips relative to the inner tube 1. Additionally, the stopper 4 can be made of a heavy metal material harmless to the human body such as platinum, gold, or tantalum, and thus can also play a role in imaging, accurately showing the position under X-ray for the convenience of the operator's operation.

[0045] As Figure 2 shown, in some of these embodiments, the intestinal anti-absorption device further includes a first handle 6 fixedly connected to the inner tube 1 and the middle tube 3, and a second handle 7 fixedly connected to the outer tube 2, so that the operator can hold the first handle 6 and the second handle 7 to control the movement of the outer tube 2 relative to the inner tube 1.

[0046] As Figure 7As shown, in some of these embodiments, one end of the middle tube 3 and the inner tube 1 remote from the seeker 11 are both fixedly coupled to the first handle 6, such that the middle tube 3 and the inner tube 1 are relatively fixed. In this embodiment, the middle tube 3 is inserted and fixed on the first handle 6, and the inner tube 1 passes through the middle tube 3 and is fixed to the first handle 6.

[0047] As Figure 7 shown, in some of these embodiments, a first through port 61 communicating with the inner cavity of the inner tube 1 is provided on the first handle 6. More precisely, the first through port 61 is aligned with the end of the inner tube 1, so that the guide wire can smoothly penetrate into the inner tube 1 through the first through port 61 to guide the intestinal anti-absorber implantation device.

[0048] As Figure 7 shown, in some of these embodiments, the second handle 7 is in a cylindrical structure and sleeved outside the middle tube 3, and one corresponding end of the outer tube 2 is inserted and fixed on the second handle 7. Specifically, a fastener 71 is provided at one end of the second handle 7 close to the seeker 11, and a flange 21 is provided at one end of the outer tube 2 close to the second handle 7. The fastener 71 is connected to the second handle 7 and clamps the flange 21 to be fixed on the second handle 7. In this embodiment, the fastener 71 is in a screwed connection with the second handle 7, so that the fastener 71 can be detachably connected to the second handle 7, and at the same time, it is convenient for the installation and disassembly of the outer tube 2 and the second handle 7.

[0049] As Figure 7 shown, in some of these embodiments, a second through port 72 is provided on the outer side of the second handle 7. The second through port 72 communicates the gap between the inner cavity of the second handle 7 and the middle tube 3, and the gap between the outer tube 2 and the middle tube 3. The gap between the outer tube 2 and the middle tube 3 communicates with the accommodation cavity 5. Specifically, there is a space between the stopper 4 and the inner wall of the outer tube 2, so that the gap between the outer tube 2 and the middle tube 3 can communicate with the accommodation cavity 5. Through the above design, during the process of operating the outer tube 2 to move relative to the inner tube 1 to release the intestinal anti-absorber 100, a certain amount of water or physiological saline can be injected into the second through port 72. The water or physiological saline enters the accommodation cavity 5 through the gap between the outer tube 2 and the middle tube 3 to moisten the intestinal anti-absorber 100, accelerating the release of the intestinal anti-absorber 100 in the duodenum. Because when releasing the intestinal anti-absorber 100, the membrane tube 120 peristalsis from the duodenum to the jejunum direction along with the peristalsis of the human intestine. During this process, the water or physiological saline will flow along the gap between the outer tube 2 and the middle tube 3 to the membrane tube 120, accelerating the peristalsis of the membrane tube 120 to the jejunum direction, thereby accelerating the release of the membrane tube 120 and accelerating the release of the intestinal anti-absorber 10,000.

[0050] To avoid the outer tube 2 moving relative to the inner tube 1 due to misoperation and accidentally releasing the intestinal anti-absorber 100, as Figure 7As shown, in some of these embodiments, an adjusting member 73 is provided at one end of the second handle 7 away from the fastener 71. The adjusting member 73 is used to lock the middle tube 3 and the second handle 7, so that the inner tube 1 is fixed relative to the outer tube 2. Specifically, the adjusting member 73 is screwed onto the second handle 7, and a locking member 74 sleeved outside the middle tube 3 is clamped between the second handle 7 and the adjusting member 73. Refer to Figure 9 As shown, a plurality of clamping blocks 741 arranged around the middle tube 3 are provided on the locking member 74. When the adjusting member 73 is screwed and cooperated with the second handle 7 and the adjusting member 73 is rotated closer to the second handle 7, the clamping blocks 741 contract and clamp onto the middle tube 3, thereby locking the middle tube 3 and the second handle 7 and fixing the inner tube 1 relative to the outer tube 2. At this time, accidental touch can be avoided to cause the intestinal anti-absorption device 100 to be accidentally released; when the adjusting member 73 is rotated away from the second handle 7, the clamping blocks 741 open and disengage from the middle tube 3, and the locking relationship between the inner tube 1 and the outer tube 2 can be released.

[0051] As Figure 7 shown, in some of these embodiments, a sealing member 75 with good elasticity and sealing performance is installed between the locking member 74 and the second handle 7. The sealing member 75 seals and resists between the second handle 7 and the locking member 74 to prevent the fluid injected from the second through-port 72 from overflowing from one end of the second handle 7 close to the adjusting member 73.

[0052] In some of these embodiments, one end of the tying wire 8 that passes out of the intestinal anti-absorption device finally passes out of the first through-port 61 on the first handle 6.

[0053] As Figure 5 and Figure 6 shown, in some of these embodiments, a first window 31 is opened on the middle tube 3 near the accommodating cavity 5. One end of the tying wire 8 that passes out of the intestinal anti-absorption device passes through the gap between the middle tube 3 and the inner tube 1 through the first window 31 until it passes out of the first through-port 61. As Figure 7 and Figure 8 shown, in addition, a guiding member 62 corresponding to the end of the inner tube 1 is fixedly installed on the first handle 6. A first through-hole 621 communicating with the inner cavity of the inner tube 1 and the first through-port 61 is opened on the guiding member 62. The inner tube 1 is inserted and fixed in the first through-hole 621 of the guiding member 62. A second through-hole 622 is also opened on the guiding member 62. One end of the tying wire 8 that passes out of the intestinal anti-absorption device sequentially passes through the second through-hole 622 and the first through-port 61.

[0054] As Figures 11 to 14As shown, in some other embodiments, a first window 31 is formed on the middle tube 3 near the accommodating cavity 5. Two inner tubes 1 are arranged side by side, and both inner tubes 1 pass through the middle tube 3. A second window 12 is formed on one of the inner tubes 1 near the first window 31 on the middle tube 3. One end of the tying wire 8 for passing out of the intestinal anti-absorbing device is sequentially passed through the first window 31, the second window 12, and the interior of the inner tube 1 provided with the second window 12 until it passes out from the first through port 61. As Figure 13 and Figure 14 shown, in addition, a guiding member 62 corresponding to the end of the inner tube 1 is fixedly installed on the first handle 6. Two first through holes 621 are formed on the guiding member 62, and the first through holes 621 communicate with the first through port 61. The two inner tubes 1 are respectively inserted and fixed in the two first through holes 621 of the guiding member 62. One end of the tying wire 8 for passing out of the intestinal anti-absorbing device sequentially passes through one of the first through holes 621 and the first through port 61. In this way, one of the inner tubes 1 can be used to guide the guide wire through, and the other inner tube 1 is used to pass through the tying wire 8 without interfering with each other.

[0055] As Figure 5 shown, in some of the embodiments, the intestinal anti-absorbing device further includes a fixing member 10. The fixing member 10 is sleeved and fixed on the middle tube 3, and one end of the tying wire 8 for fixing on the middle tube 3 is pressed against the middle tube 3.

[0056] As Figure 2 or Figure 7 shown, in some of the embodiments, the intestinal anti-absorbing device further includes a pull ring 9. The pull ring 9 is fixed to one end of the tying wire 8 that passes out of the intestinal anti-absorbing device, so that the operator can pull the tying wire 8 through the pull ring 9 to untie the binding of the tying wire 8 to the intestinal anti-absorbing device 100.

[0057] In some of the embodiments, when the intestinal anti-absorbing device releases the intestinal anti-absorbing device 100, the inner tube 1 is fixed and the outer tube 2 is moved to open the accommodating cavity 5 to complete the release of the intestinal anti-absorbing device 100.

[0058] The operation of the intestinal anti-absorbing device provided by the embodiments of the present invention is described as follows:

[0059] First, the folded intestinal anti-absorbing device 100 is received in the accommodating cavity 5. Subsequently, under the guidance of the guide wire, the guiding head 11 of the intestinal anti-absorbing device is sent into the body. The first handle 6 is fixed and the adjusting member 73 is unlocked, and the second handle 7 is retracted to be close to the first handle 6 to open the accommodating cavity 5 so that at least part of the intestinal anti-absorbing device 100 is exposed. Subsequently, the intestinal anti-absorbing device 100 is gradually released and unfolded by pulling the tying wire 8 until the intestinal anti-absorbing device 100 is completely released and unfolded.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
