Laparoscopic surgery needs to enter the abdominal cavity before the beginning of the start of the cavity. The Hasson method is currently a standard puncture in laparoscopic surgery.

1.hasson puncture method
The Hasson method is currently the standard Trocar entry method of laparoscopic surgery. It is required to open the abdominal wall structure in an open field to open the abdominal wall layer by layer and separate until the peritoneal cavity gap.

The process of opening the abdominal wall structure of the Hasson puncture method is clear and visible, avoiding the risk of damaging the internal organs in the abdominal cavity, because the separation of layers of separation can be treated in time in time. method.

2. Stranging operation
Make a 10-12 mm long vertical or horizontal or curved skin incision on the lower or upper edge of the umbilicus. The selection of the incision position can be based on the preferences of the surgeon or considering the adhesion at the previous incision. Use thin narrow hooks or Kelly hematopoietic tongs to separate subcutaneous fat and tissue. After seeing the white line of the abdomen, you can clamp the two sides of the hematopoietic pliers and lift it up. Make a 10 mm vertical incision. Continue to separate the hematopoietic pliers. It can be seen that the white thick peritoneum can be seen. Use a pair of hematopoietic pliers to grab the sides of the peritoneal and lift it up. Carefully open the peritoneum with a surgery knife. Traction lines are used to attract peritoneal and white lines and subsequently used to fix the Hasson sheath tubes.

Next, you need to confirm whether you have successfully entered the abdominal cavity. The surgeon inserts the small finger to the incision. Using this action can verify whether the opening is sufficient to insert into the sheath tube, and at the same time, it can touch the local situation. Usually the peritoneum of this part is free, but occasionally there may be some thin omentum adhesions, which can be pushed away by hand. Insert the Hasson sheath tube with a blunt head core into the abdominal cavity, spin the spiral sleeve into the fascia to prevent air leakage, and then fix the stitching on both sides on the grooves on both sides of the tube. Then pull out the core, connect to the gas injection tube, turn on the switch, set the flow rate and drunk pressure of the gas (15 mmHg, the elderly patients should be appropriately reduced). When the abdominal wall is drumming, observe the total pressure of the abdominal cavity and the total amount of gas injected.

If there is a large omentum adhesion and a rough velvet ligament, the lens may not be smooth when entering the abdominal cavity through the end of the Hasson sheath. If the surgeon has no abnormally discovery of the touch inspection of this part of this part, the rotation and adjustment of the lens angle can usually find the correct way. If the entrance cannot be found, you should pull out the tube and re -investigate before inserting it. In extremely individual cases, due to the dense adhesion, if the finger detection cannot find a feasible path, the position of inserting the Hasson sheath should be replaced.


Unimicro Hasson puncture
Hasson type puncture (applicable to obese patients)
Specification: 10mmx100mm, 12mmx100mm
Dark round head knife, reduce puncture damage, is suitable for most patient surgery, especially patients with obesity and abdominal adhesion, the protection of organs is good;
Full separation structure provides more operations for clinical operations;
With the fixed device of the abdominal wall, the length of the sleeve can be adjusted, and the fixed wing of the abdominal wall can be strengthened
