Background
With the increasing popularity of minimally invasive surgery, the use of linear cutting staplers has been quite frequent. The linear cutting anastomat comprises a nail bin seat assembly, a sleeve assembly and a gun body assembly.
The key using steps of the linear cutting anastomat are as follows: 1. selecting tissue to be anastomosed for cutting; 2. pre-pressing tissues, namely, giving tissue pressure to the same position to be cut by the anastomat in advance, pressing, and preparing to form staples, wherein the tissue thickness is the tissue thickness when the staples are fired; 3. when the anastomotic nail is fired, the anastomotic nail can form a B shape in tissues after being fired under an ideal state, and the anastomosis is finished.
The staple forming effect of the anastomotic staples is very important for realizing one of the functions of the anastomat, namely anastomosis. Each staple has a range of tissue thicknesses for which it is suitable. When the tissue thickness exceeds or is lower than the range in which the anastomosis nail can effectively work, the anastomosis nail is difficult to effectively lock the anastomosis opening, complications such as bleeding, liquid leakage, air leakage and the like easily occur, and in addition, the excessive tissue thickness also easily causes excessive squeezing pressure to cause tissue damage and even necrosis.
At present, most of clinical mainstream staples have 2-4 staple cartridge specifications, the lower limit of the applicable tissue thickness range is about 1-2.3mm, the upper limit is about 2-4mm, the span is about 0.7-1.7mm, and the selection of the staple cartridge completely depends on the visual inspection and experience of doctors. Under the complicated and tense operation environment, the doctor is easy to have errors in selecting the nail bin in the face of such small differences. The literature reports that the incidence rate of anastomotic leakage in colorectal surgery can reach 30 percent.
