[0027] like Figure 1-Figure 4 As shown, the utility model provides a flushing and drainage device suitable for placement in laparoscopic surgery, comprising an outer sleeve 1, an inner core suction tube 3 and a sealing membrane 2.
[0028] The outer tube 1 is closed at one end and open at the other end. A flushing channel 12 is provided in the tube wall along the length direction. A plurality of drainage holes 11 are also provided on the tube wall. A flushing channel interface 4 is provided at one end of the flushing channel 12 for connecting with saline flushing liquid. The other end is open and extends to the closed end of the outer tube 1. The drainage holes 11 are divided into a plurality of groups, and each group of drainage holes 11 is evenly arranged along the circumference of the outer tube 1. Figure 4 As shown, in some embodiments, each group of drainage holes is provided with 4, and adjacent drainage holes 11 in the same group are arranged on the outer sleeve 1 at intervals of a quarter of a circle, and drainage holes 11 in different groups are arranged along the length direction of the outer sleeve 11, and the spacing between drainage holes 11 in adjacent groups is the same. The drainage holes 11 and the flushing channels 12 are arranged alternately, and after the physiological saline enters the flushing channel 12 through the flushing channel interface 4, it can flow all the way to the end of the flushing channel 12, enter the abdominal cavity, flush the contents of the abdominal cavity, and then be sucked into the outer sleeve 1 through the drainage holes 11. In some embodiments, the outer wall of the outer sleeve 1 is provided with scale marks, which start from the closed end of the outer sleeve 1 and are distributed along the length direction of the outer sleeve 1.
[0029] Both ends of the inner core suction tube 3 are open, and the length of the inner core suction tube 3 is greater than the outer sleeve 1, and the outer diameter is smaller than the inner diameter of the outer sleeve 1. In the use state, one end of the inner core suction tube 3 is placed in the outer sleeve 1, and the other end is placed outside the outer sleeve 1, connected to the suction device. In some embodiments, a protrusion 32 is provided on the inner core suction tube 3. After the inner core suction tube 3 is placed in the outer sleeve 1, the protrusion 32 can abut against the inner wall of the outer sleeve 1, so that the inner core suction tube 3 can be fixed in the outer sleeve 1. In some embodiments, the inner core suction tube 3 includes a tapered inner core suction tube interface 31 at one end outside the outer sleeve 1, so as to better connect the suction device.
[0030] In the initial state, the sealing film 2 is adhered to the inner wall of the outer tube 1, covering the drainage hole 11. In the use state, the sealing film 2 can be torn off the inner wall of the outer tube 1. In some embodiments, a tear strip 21 is connected to the sealing film 2, and the tear strip 21 can be pulled to separate the sealing film 2 from the inner wall of the outer tube 1. Preferably, the connection between the tear strip 21 and the sealing film 2 is located at the closed end of the outer tube 1, so that the sealing film 2 can be completely torn off from the inner wall of the outer tube 1; the other end of the tear strip 21 extends out of the outer tube 1, which is convenient for the operator to pull.
[0031] The method of using the utility model is as follows: when performing laparoscopic surgery, the closed end of the outer sleeve 1 is extended into the patient's abdominal cavity, and the open end is located outside the patient's body. After placement, due to the presence of the sealing film 2, the drainage hole 11 is sealed, and pneumoperitoneum will not be affected; after the operation is over, the sealing film 11 is torn off to expose the drainage hole 11, and the inner core suction tube 3 is placed in the outer sleeve 1, and physiological saline is introduced into the flushing channel. The physiological saline flows into the abdominal cavity to flush the contents of the abdominal cavity, and at the same time, the end of the inner core suction tube 3 located outside the body is connected to a negative pressure suction device for suction, so that negative pressure is formed inside the outer sleeve 1. Under the action of the negative pressure, the flushing fluid in the abdominal cavity is sucked into the outer sleeve 1 from the abdominal cavity through the drainage hole 11, and is discharged from the inner core suction tube 3 out of the body.
[0032] In summary, the flushing and drainage device provided by the utility model and suitable for placement in laparoscopic surgery can be used in laparoscopic surgery, the closed end of the outer sleeve is extended into the patient's abdominal cavity, and the open end is located outside the patient's body. Since a sealing film is arranged inside the outer sleeve, the drainage hole will not leak, and the pneumoperitoneum will not be affected. After the operation, the sealing film can be torn off, and then physiological saline can be dripped into the flushing channel for flushing. The physiological saline can enter the outer sleeve through the drainage hole, and be sucked out by the inner core suction tube inserted in the outer sleeve to discharge the contents of the abdominal cavity.
