Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical apparatus and instruments, especially to a NOSES operation rectal flushing sterilizer. BACKGROUND

[0002] NOSES operation is the abbreviation of natural orifice specimen extraction surgery. The main feature of this operation is to take out the surgical specimen through the natural orifice of the human body, such as the anus, without the need for an incision on the abdominal wall. NOSES operation leaves only a puncture on the abdominal wall, which is a minimally invasive surgical technique characterized by rapid recovery and less pain.

[0003] As an advanced minimally invasive surgical technique, NOSES operation provides a better treatment option for patients with colorectal cancer and other diseases. During colorectal NOSES operation, feces or intestinal fluid may flow out when the distal rectum is opened, contaminating the abdominal cavity. To reduce the risk of infection and promote wound healing, the intestinal tract needs to be flushed and disinfected during the operation. The traditional flushing method is to use a syringe to inject physiological saline into the intestinal tract from the anus, but this method has some drawbacks. For example, the contaminated liquid after flushing will directly flow out from the anus, which will cause repeated contamination, reducing the flushing efficiency and effect. In addition, the syringe can only be placed in a shallow position in the anus, and cannot achieve deep cleaning effect, thus requiring multiple flushing, making the operation steps cumbersome.

[0004] The Chinese utility model patent with publication number CN 208756659 U discloses a rectal flushing device used during rectal anastomosis operation, which includes a syringe, a piston rod, a piston, an injection port, a rubber ring, a flushing pipe, an inflation pipe, a sealing ring, a hand squeeze air pump, an exhaust port, a rubber plug, a side hole, an air bag, a communication pipe, a threaded protrusion, and a hydrophilic coating. This technology is provided with a flushing pipe, which is provided with a side hole. During flushing, the flushing pipe is placed into the rectum from the anus, and then the flushing liquid is sprayed out from the side hole by pressing the syringe, so as to flush the intestinal tract. Although this technology can achieve better flushing effect compared to directly using a syringe for flushing, it does not have a drainage function, and the liquid after flushing will still flow out directly from the anus, also reducing the flushing effect.

The second elastic sheet 703 and the second limiting part 702 jointly form an anti-backflow device, and the opening and closing of the second through hole 704 is completed by using the elastic property of the second elastic sheet 703.

[0053] Please refer to Figure 3 As shown, the nozzle 101 comprises a nozzle bottom 1011 and a spraying surface 1012; the front end surface of the nozzle bottom 1011 is connected with the spraying surface 1012, and the rear end surface of the nozzle bottom 1011 is connected with the pipe body 102; the nozzle bottom 1011 is provided with a third through hole 1013, and the nozzle cavity 103 is in communication with the water inlet channel 104 through the third through hole 1013; the spraying surface 1012 is provided with a plurality of spraying holes 106; the spraying surface 1012 is in a semispherical shape, and the plurality of spraying holes 106 are distributed on the semispherical spraying surface 1012; when the physiological saline is sprayed from the plurality of spraying holes 106, a shower-like water flow can be formed, so that a better flushing effect can be achieved.

[0054] Please refer to Figure 7As shown, the pipe body 102 comprises an annular pipe wall 1021 and a plurality of arc-shaped pipe walls 1022, each of which is connected to the inner wall of the annular pipe wall 1021, and each of which, together with the inner wall of the annular pipe wall 1021, forms a water inlet channel 104; a plurality of drainage holes 107 are formed on the annular pipe wall 1021; further, the bottom 1011 of the nozzle is provided with a plurality of third through holes 1013 equal in number to the water inlet channels 104, and each water inlet channel 104 communicates with the nozzle cavity 103 through a third through hole 1013. Such a design not only forms the water inlet channel 104, but also the plurality of arc-shaped pipe walls 1022 can support the inside of the annular pipe wall 1021, so that the pipe body 102 is not easy to deform when subjected to external force, thereby ensuring that each channel in the drainage tube 1 remains unobstructed.

[0055] Please refer to Figure 7 As shown, the plurality of arc-shaped pipe walls 1022 are uniformly arranged along the circumference of the annular pipe wall 1021, and a plurality of drainage holes 107 are arranged between each adjacent two arc-shaped pipe walls 1022; the plurality of drainage holes 107 arranged between each adjacent two arc-shaped pipe walls 1022 are distributed along the length direction of the annular pipe wall 1021 and are distributed in the front part of the annular pipe wall 1021. In this way, the plurality of drainage holes 107 are distributed on the outer periphery of the front part of the annular pipe wall 1021, thereby achieving better drainage effect

[0056] The outer wall of the drainage tube 1 is provided with a scale line 8, so as to facilitate the viewing of the depth of the drainage tube 1 entering the intestinal tract.

[0057] Further comprising a leak-proof plug 9, which is detachably sleeved on the drainage tube 1; the cross-sectional area of the leak-proof plug 9 gradually shrinks from the rear end to the front end; preferably, the leak-proof plug 9 is made of elastic material. In use, the leak-proof plug 9 is sleeved from the front end of the drainage tube 1, and the depth of the drainage tube 1 entering is determined according to the position of the operation, so as to determine the fixed position of the leak-proof plug 9 on the drainage tube 1. Then the drainage tube 1 is placed into the intestinal tract from the anus until the leak-proof plug 9 is placed at the anus. At this time, the front end of the leak-proof plug 9 enters the anus, blocking the gap between the drainage tube 1 and the anus, which can prevent the liquid after flushing from flowing out. In addition, after the leak-proof plug 9 is installed on the drainage tube 1, the inner wall of the leak-proof plug 9 is in close contact with the outer wall of the drainage tube 1, which can prevent the liquid after flushing from flowing out between them. Further, when the pipe body 102 is placed in a shallow position of the intestinal tract, the rear drainage holes 107 may leak outside, and the leak-proof plug 9 can block the drainage holes 107 placed outside.

[0058] The leakage-proof plug 9 is provided with a through channel 901, and a limiting protrusion 902 is arranged in the through channel 901, and the limiting protrusion 902 is matched with the drainage hole 107. The leakage-proof plug 9 is provided with a through channel 901, and one or more limiting protrusions 902 are arranged in the through channel 901. The pipe wall of the pipe body 102 is provided with a plurality of drainage holes 107, and one limiting protrusion 902 is matched with each drainage hole 107. When the leakage-proof plug 9 is installed, the drainage tube 1 is inserted through the through channel 901 of the leakage-proof plug 9, and the fixed position is determined according to the actual needs. In this process, the leakage-proof plug 9 is fixed by embedding the one or more limiting protrusions 902 into the corresponding drainage hole 107. This design ingeniously uses the drainage hole 107 as a positioning groove, simplifies the structure, and improves the stability.

[0059] The control valve 10 is further arranged on the connecting pipe 3. Preferably, the control valve 10 is a flow regulator, and the speed of drainage is adjusted by controlling the flow regulator.

[0060] Further, in a preferred embodiment, the pipe body 102 has a slight arc, which is more convenient for the pipe body 102 to smoothly enter the intestinal tract.

[0061] Further, in a preferred embodiment, the outer diameter of the pipe body 102 is 1.2 cm; the outer diameter of the air pipe 5 is 3 mm; the length of the drainage tube 1 ranges from 20 cm to 25 cm; the axial length of the leakage-proof plug 9 is 5 cm; and the distance between the drainage hole 107 farthest from the nozzle 101 and the front end of the drainage tube 1 is 8 cm.

[0062] Working principle:

[0063] In use, first, the leakage-proof plug 9 is sleeved on the front end of the drainage tube 1, and the depth of the drainage tube 1 entering the intestinal tract is determined according to the position of the operation, so as to determine the fixed position of the leakage-proof plug 9 on the drainage tube 1. Then the drainage tube 1 is inserted into the intestinal tract from the anus until the leakage-proof plug 9 is placed at the anus. Then the syringe containing physiological saline is connected with the first connecting head 6. When the syringe is pushed, the liquid exerts pressure on the top surface of the first elastic sheet 603 after passing through the first through hole 604, causing the first elastic sheet 603 to deform and separate the top surface from the first contact surface, forming a gap. Then the liquid flows into the water injection pipe 4 from the gap between the first elastic sheet 603 and the first contact surface. Subsequently, the liquid sequentially passes through the water inlet cavity 202, the water inlet channel 104, the third through hole 1013 and the nozzle cavity 103, and finally is sprayed from the spraying hole 106, realizing the flushing and disinfection of the intestinal tract.

[0064] After the flushing is completed, the liquid needs to be led out of the intestinal tract. For this purpose, the connecting tube 3 is connected to the negative pressure device, and after the negative pressure device is started, a negative pressure is generated in the drainage channel 105, so that the liquid in the intestinal tract is sucked into the drainage channel 105 from the drainage hole 107. Then the liquid passes through the connecting channel 201 into the connecting tube 3, and finally is introduced into the negative pressure device. The drainage process can be adjusted by the control valve 10 to adjust the drainage speed. In addition, since the vent pipe 5 is in communication with the connecting channel 201, when the negative pressure device is working, a negative pressure is also generated in the vent pipe 5, and when the negative pressure in the vent pipe 5 reaches a threshold value that can make the second elastic sheet 703 deform, the top surface of the second elastic sheet 703 separates from the second contact surface to form a gap. Air enters the vent pipe 5 through this gap, so as to balance the air pressure inside and outside the system.
