Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anal dilation and irrigation device. Background Art

[0002] Anal irrigation is a crucial step in rectal cancer surgery, ensuring a clean surgical area and ensuring optimal conditions for a smooth procedure. Currently, anal irrigation using a bulb and saline solution is often used in clinical practice. However, this traditional irrigation method has significant drawbacks, creating complications and risks during surgery.

[0003] First, the irrigating fluid is prone to spraying out of the anus. When using an irrigating bulb to inject saline, precise pressure control is difficult, often resulting in large amounts of irrigating fluid spraying out of the anus quickly. This not only contaminates the surgical field, hindering the surgeon's clear observation of the surgical site and increasing the difficulty of the procedure, but also easily contaminates the surgeon's clothing and surgical instruments, significantly increasing the potential risk of surgical infection.

[0004] Secondly, the force of finger dilation is uneven. Before performing anal irrigation, it is often necessary to dilate the anus first, and the traditional method is mostly to rely on fingers to dilate the anus. However, it is difficult for different doctors or the same doctor to maintain a stable and consistent force of finger dilation at different times. Excessive force can easily cause perianal tears, which not only causes additional trauma to the patient, but may also cause a series of postoperative complications such as bleeding and infection, affecting the patient's postoperative recovery.

[0005] Finally, traditional anal dilators are too rigid and lack progressive adjustment. Existing anal dilators are generally made of too hard a material, making them difficult to flexibly adjust to the patient's specific needs. Furthermore, they lack progressive adjustment to gradually adapt to the patient's anal dilation needs, further increasing the difficulty of operation and the potential for injury.

[0006] In summary, the current anal irrigation method of injecting saline with an irrigation ball and the accompanying anal dilation method used in rectal cancer surgery have the risk of causing injury to patients. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. It is apparent that the described embodiments are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0042] like Figures 1 to 15 As shown, an anal dilation and flushing device in an embodiment of the first aspect of the present invention includes a multi-stage airbag 1, a water barrier 2 and a flushing assembly. An airbag hole 11 is provided in the middle of the multi-stage airbag 1, the water barrier 2 is installed on the side wall of the multi-stage airbag 1 and covers the airbag hole 11, and the flushing assembly is inserted on the water barrier 2, and the flushing assembly is used for flushing the anus.

[0043] In the above embodiment, it should be noted that the multi-stage airbag includes a plurality of elliptical ring-shaped or circular ring-shaped airbags which are sequentially arranged and connected from the inside to the outside, a pressure sensor 15 is provided between each two adjacent airbags, and an air tube 7 is provided on each airbag. Each airbag is connected to a small air pump or a hand-pressed airbag through the air tube 7, and the water barrier 2 is connected to the side wall of the innermost airbag or any one of the other airbags.

[0044] Specifically, taking three airbags as an example, they are the first airbag 12, the second airbag 13 and the third airbag 14. The first airbag 12, the second airbag 13 and the third airbag 14 are arranged concentrically. The first airbag 12 is located on the periphery of the second airbag 13, and the second airbag 13 is located on the periphery of the third airbag 14. The water retaining member 2 is installed on the surface of the third airbag 14, the surface of the second airbag 13 or the surface of the first airbag 12, and the water retaining member covers the airbag hole 11 of the third airbag 14. The setting of multiple airbags realizes the graded inflation of the multi-stage airbag 1. When it is needed When the size of the anus to be expanded is small, it is only necessary to inflate the inner airbag to reach the corresponding anus size to ensure sufficient pressure. When the size of the anus to be expanded is large, both the outer and inner airbags are inflated and the inflation is stopped after the anus is opened to a sufficient size to achieve the effect of anal expansion. When the anal expansion is completed, the flushing component is used to flush the anus. The setting of the water barrier 2 can prevent the flushing water from spraying onto the body or face of the medical staff; the setting of the pressure sensor 15 can provide real-time feedback on the pressure exerted on the multi-stage airbag 1 to avoid excessive expansion of the multi-stage airbag 1.

[0045] The water retaining member is made of silicone material or other medical flexible materials, and the multiple air bags are all made of uniform materials.

[0046] The technical effect achieved by the above embodiment is: the expansion strength can be adjusted step by step through the setting of multi-stage airbags to avoid tissue damage caused by single excessive expansion. At the same time, the flexible material of the multi-stage airbags fits the anal anatomical structure, provides uniform support, and reduces the risk of slippage.

[0047] By setting the through hole in the middle of the multi-stage airbag, an operating channel is reserved for the flushing component without affecting the expansion effect, thereby ensuring the continuity of treatment.

[0048] Optional, such as Figures 1 to 15 As shown, in some embodiments, an airbag positioning component 4 is further included. The airbag positioning component 4 is installed on the water retaining member 2. The airbag positioning component 4 is used to insert the multi-stage airbag 1 on the anus.

[0049] In the above optional embodiments, it should be noted that the airbag positioning component 4 can be a separate cylindrical rod with a rod size between 2mm and 5mm. The airbag positioning component 4 is connected to the water retaining part 2 by injection molding or bonding. When working, the airbag positioning component 4 is inserted into the anus with the multi-stage airbag 1, and then the multi-stage airbag 1 is opened to expand the anus, so that the flushing component can be operated to achieve flushing of the anus.

[0050] The airbag positioning assembly 4 can also be composed of a telescopic rod structure, which drives the multi-stage airbag 1 to be inserted into the anus to achieve expansion of the anus.

[0051] The beneficial effect of the above optional embodiment is that the multi-stage airbag 1 can reliably expand the anus through the provision of the airbag positioning assembly 4 .

[0052] Optional, such as Figures 1 to 15 As shown, in some embodiments, the airbag positioning assembly 4 includes a fixed sleeve 41, an intermediate telescopic rod 42 and a tail telescopic rod 43. The fixed sleeve 41 is installed on the water retaining member 2, the intermediate telescopic rod 42 is slidably connected to the fixed sleeve 41, and the tail telescopic rod 43 is slidably connected to the intermediate telescopic rod 42. The airbag positioning assembly 4 also includes a pull-out rod 44, one end of which passes through the fixed sleeve 41 and the intermediate telescopic rod 42 in sequence and is detachably connected to the tail telescopic rod 43.

[0053] In the above optional embodiment, it should be noted that the number of the intermediate telescopic rods 42 can be one or more, and the specific number is set according to actual needs, and the multiple intermediate telescopic rods 42 are slidably connected in sequence.

[0054] The fixing sleeve 41 , the middle telescopic rod 42 and the tail telescopic rod 43 are all made of hard or rigid materials.

[0055] The fixed sleeve 41 includes a fixed cylinder 411, a fixed plate 412, a first stopper 414 and a first retaining ring 415. The inner wall of the fixed cylinder 411 is provided with a first sliding groove 413. The outer wall of the fixed cylinder 411 is connected to the fixed plate 412 by bonding, injection molding, screw connection or welding connection. The inner wall of the first end of the fixed cylinder 411 is connected to the first retaining ring 415 by bonding, injection molding, screw connection or welding connection. A first stopper 414 is provided in the first sliding groove 413. The first stopper 414 and the first retaining ring 415 are respectively located at the opposite ends of the fixed cylinder 411. The fixed plate 412 and the water retaining part 2 are connected by bonding, injection molding, screw connection or welding connection.

[0056] Each intermediate telescopic rod 42 includes an intermediate sliding rod 421, a second retaining ring 422, a first slider 424 and a second stopper 425. The inner side wall of the intermediate sliding rod 421 is provided with a second sliding groove 423, the inner side wall of the first end of the intermediate sliding rod 421 is provided with a second retaining ring 422, the outer side wall of the first end of the intermediate sliding rod 421 is provided with a first slider 424, the second end of the intermediate sliding rod 421 is provided with a second stopper 425 and the second stopper 425 is located in the second sliding groove 423; the intermediate sliding rod 421 is slidably connected to the fixed cylinder 411 through the first slider 424, specifically, the first slider 424 is slidably connected to the first sliding groove 413.

[0057] The tail telescopic rod 43 includes a tail sliding rod 431, a ball head 432, a second slider 433 and a connecting ring 434, including a side wall of the tail sliding rod 431 connected to the second slider 433 by bonding, injection molding, screw connection or clamping, etc., a first end of the tail sliding rod 431 is provided with a ball head 432, the second slider 433 is slidably connected to the second slide groove 423, at least one water pipe through hole 435 is opened on the tail sliding rod 431, the water pipe through hole 435 passes through the tail sliding rod 431 and the ball head 432, and a connecting ring 434 is provided at the first end of the tail sliding rod 431.

[0058] The pulling rod 44 includes a rod body 441, a connecting part 442 and a handle 443. One end of the rod body 441 is connected to the connecting part 442 by bonding, injection molding or screw connection, and the other end of the rod body 441 is connected to the handle 443 by bonding, injection molding or screw connection. The connecting part 442 is connected to the connecting ring 434 by screw connection or clamping.

[0059] It also includes a connecting piece 10 . Optionally, a first end of the connecting piece 10 is connected to the tail telescopic rod 43 , and a second end of the connecting piece 10 is connected to the water retaining member 2 .

[0060] The operating principle of this airbag positioning assembly 4 is as follows: the middle telescopic rod 42 and the tail telescopic rod 43 slide within the fixed sleeve 41, allowing the assembly's length to be adjusted according to actual needs. To extend the airbag positioning assembly 4, the handle 443 of the pull-out rod 44 is pulled. Because the connecting portion 442 of the pull-out rod 44 is connected to the connecting ring 434 of the tail telescopic rod, the pull-out rod drives the tail telescopic rod 43 to move. The second slider 433 of the tail telescopic rod 43 slides on the second chute 423 of the middle telescopic rod 42, and the first slider 424 of the middle telescopic rod 52 slides on the first chute 413 of the fixed sleeve 41, thereby extending the tail telescopic rod 43 and the middle telescopic rod 42. If there are multiple middle telescopic rods 42, they are connected in a sliding manner. When the pull-out rod is pulled, the multiple middle telescopic rods are extended in sequence. Similarly, to retract the assembly, pushing the pull-out rod causes the telescopic rods to slide back in the opposite direction.

[0061] The first stopper 414 and first retaining ring 415 of the fixed sleeve, and the second stopper 425 and second retaining ring 422 of the middle telescopic rod, act as position limiters. The first stopper 414 and first retaining ring 415, located at opposite ends of the fixed sleeve 411, restrict the sliding range of the middle telescopic rod within the fixed sleeve. The second stopper 425 and second retaining ring 422 restrict the sliding range of the tail telescopic rod within the middle telescopic rod, preventing it from slipping out.

[0062] Connection and Operation of the Extension Rod 44: The extension rod's connecting portion 442 is connected to the rear telescopic rod's connecting ring 434 via a screw or snap connection, ensuring stable movement of the rear telescopic rod when the extension rod is pulled or pushed. The handle 443 is designed to facilitate operator application of force and control of the assembly's extension and retraction.

[0063] The beneficial effects of the above optional embodiments are as follows: First, multi-stage rigid telescopic expansion and contraction achieves precise positioning and stable support; the fixed sleeve 41, the intermediate telescopic rod 42, and the tail telescopic rod 43 are all made of hard materials such as medical plastics or metal materials, and the multi-stage chute and block cooperate (for example, the first chute 413 and the first slider 424, the second chute 423 and the second slider 433) to form an axial telescopic adjustment mechanism. When the telescopic rods are gradually expanded, the blocks (such as the first block 414 and the second block 425) and the retaining rings (such as the first retaining ring 415 and the second retaining ring 422) form upper and lower limit structures, which can not only accurately control the telescopic length, but also prevent the intermediate telescopic rod 42 and the tail telescopic rod 43 from excessively slipping, ensuring that the multi-stage airbag 1 maintains stable support during intra-anal expansion. The ball head 432 at the end of the tail telescopic rod 43 is further configured to fit the physiological curvature, reducing tissue friction damage.

[0064] Second, the pull rod 44 is detachably connected to the connecting ring 434 of the rear telescopic rod 43 via the connecting portion 442. The surgeon simply pulls the handle 443 to control the expansion and contraction of the multi-stage telescopic rod, eliminating the tedious adjustment process. The rod body 441 passes through the fixed sleeve and the interior of the telescopic rod, forming an axial linkage. This simplifies the structural complexity, ensures that the direction of force is consistent with the telescopic trajectory, and reduces the risk of operational errors. The water pipe hole 435 of the rear telescopic rod 43 integrates a flushing pipeline channel to prevent external pipeline entanglement and interference with positioning.

[0065] One end of the connecting piece 10 is fixed to the rear telescopic rod, and the other end is connected to the water retaining member, so that when the airbag positioning assembly 4 is extended, the multi-stage airbag 1 can be driven to be inserted into the anus, thereby ensuring the reliability of anal dilation.

[0066] Optional, such as Figures 1 to 15 As shown, in some embodiments, the flushing assembly includes a liquid inlet pipe 3. When in operation, the first end of the liquid inlet pipe 3 passes through the fixed sleeve 41, the middle telescopic rod 42 and the tail telescopic rod 43 in sequence and is then placed in the anus.

[0067] In the above optional embodiments, it should be noted that the second end of the liquid inlet tube 3 can be connected to a liquid pump or a negative pressure liquid suction device. When flushing is required, the second end of the liquid inlet tube 3 is connected to the liquid pump. When the flushing is completed and the flushing liquid needs to be discharged, the second end of the liquid inlet tube 3 is connected to the negative pressure liquid suction device to realize the discharge of the liquid; at this time, only one water pipe through hole 435 is required; in addition, a pressure sensor 31 is also included. A pressure sensor 31 is provided on the liquid inlet tube 3 to realize the measurement of the air pressure when air is pumped into the anus after the anus is flushed, so as to avoid the occurrence of anastomotic rupture caused by excessive air pressure.

[0068] The beneficial effect of the above optional embodiment is that the cleaning liquid can be effectively injected into the anus through the provision of the liquid inlet tube 3 to achieve sufficient cleaning of the anus.

[0069] Optional, such as Figures 1 to 15 As shown, in some embodiments, the flushing assembly further includes a liquid outlet pipe 5. During operation, one end of the liquid outlet pipe 5 passes through the fixed sleeve 41, the middle telescopic rod 42 and the tail telescopic rod 43 in sequence and is then placed in the anus.

[0070] There is a gap between the liquid outlet pipe 5 and the liquid inlet pipe 3.

[0071] In the above optional embodiment, it should be noted that the other end of the liquid outlet pipe 5 is connected to a negative pressure liquid aspirator by means of screw connection or clamping to discharge the liquid after cleaning; at this time, there are two water pipe holes 435, and the liquid inlet pipe and the liquid outlet pipe are respectively arranged on one water pipe hole 435.

[0072] It also includes a valve 9, which is provided on both the liquid inlet pipe 3 and the liquid outlet pipe 5. The valve 9 is a solenoid valve or a manual valve.

[0073] The beneficial effect of the above optional embodiment is that the liquid after cleaning can be reliably discharged through the provision of the liquid outlet pipe 5 .

[0074] Optional, such as Figures 1 to 15 As shown, in some embodiments, the flushing assembly further includes a nozzle 8, and the nozzle 8 is connected to the first end of the liquid inlet pipe 3 by bonding, injection molding, screw connection, or clamping.

[0075] In the above optional embodiment, it should be noted that the nozzle 8 is a multi-hole nozzle.

[0076] The beneficial effect of the above optional embodiment is that the flushing effect of the anus can be guaranteed by the arrangement of the nozzle 8.

[0077] Optional, such as Figures 1 to 15 As shown, in some embodiments, a resisting mounting member 6 is further included, and the water-blocking member 2 is connected to the multi-stage airbag 1 through the resisting mounting member 6; the resisting mounting member 6 includes a connecting plate 61, and the water-blocking member 2 includes a first baffle 21, a second baffle 25 and a connecting portion 442, the connecting plate 61 is installed on one side of the multi-stage airbag 1, the first baffle 21 is connected to the connecting plate 61, and the second baffle 25 is connected to the first baffle 21 through the connecting portion 442; the resisting mounting member 6 also includes a connecting retaining ring 62, and the water-blocking member 2 also includes a retaining edge 22, the first baffle 21 is provided with a retaining edge 22, the connecting plate 61 is provided with a connecting retaining ring 62, and the connecting retaining ring 62 is connected to the retaining edge 22.

[0078] In the above optional embodiment, it should be noted that the second end of the connecting piece 10 can also be connected to the resisting mounting member 6; the resisting mounting member 6 and the water retaining member 2 are both made of flexible silicone material or other medical flexible materials.

[0079] The connecting plate 61 is connected to the multi-stage airbag 1 by bonding or injection molding, the connecting retaining ring 62 and the connecting plate 61 are integrally injection-molded, the retaining edge 22 and the first baffle 21 are integrally injection-molded, the connecting portion 442 includes a first connecting portion 23 and a second connecting portion 24, and the first baffle 21 and the second baffle 25 are connected in turn with the first connecting portion 23 and the second connecting portion 24 by bonding or injection molding.

[0080] A first through hole 26 is defined on the second baffle 25 , and a second through hole 63 is defined on the connecting plate 61 . The first through hole 26 and the second through hole 63 are coaxially arranged. A slot 27 is defined on the second baffle 25 , and the fixing plate 412 is disposed in the slot 27 by bonding or injection molding, and the slot 27 is connected to the first through hole 26 .

[0081] The retaining edge 22 is disposed on the outer periphery of the connecting retaining ring 62 and is bonded to the connecting retaining ring 62 .

[0082] During operation, the first baffle 21 is located on one side of the multi-stage airbag 1 , and the second baffle 25 is located on the other side of the multi-stage airbag 1 to ensure the sealing effect during operation. The first connecting portion 23 and the second connecting portion 24 are both located in the airbag hole 11 .

[0083] The beneficial effects of the above optional embodiment are: the resisting mounting part 6 and the water retaining part 2 are integrally injection-molded with flexible materials such as medical silicone, and the connecting plate 61 is tightly bonded to the multi-stage airbag 1 to form a flexible transition interface.

[0084] The first baffle 21 of the water retaining member is connected to the connecting retaining ring 62 through the retaining edge 22, and cooperates with the setting of the second baffle 25. It can adaptively bend as the perianal tissue deforms when the multi-stage airbag 1 is inflated and expanded, thereby maintaining the seal between the water retaining member 2 and the anal wall, avoiding overflow of flushing fluid or infiltration of pollutants, and reducing the risk of mucosal damage caused by rigid friction. It is especially suitable for patients with large differences in anal sphincter tension.

[0085] The first baffle 21 and the second baffle 25 are connected by the first connecting portion 23 and the second connecting portion 24 to form an adjustable folding structure, which can be compressed to facilitate placement, and can be fixed with the assistance of the connecting piece 10 and the resisting mounting member 6 after unfolding to form a multi-directional mechanical support.

[0086] The nested locking of the retaining edge 22 and the connecting retaining ring 62 constitutes an axial anti-slip mechanism, which effectively resists the device displacement caused by the impact of the flushing fluid or intestinal peristalsis, ensuring that the position of the water retaining member 2 is constant during the treatment process.

[0087] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.

[0088] The terms "upper", "lower", "left", "right", "middle", etc. used in this specification are only for the convenience of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the present invention without substantially changing the technical content.
