Trocar intorduction:
Speaking of laparoscopic surgery, people are not unfamiliar, usually 2-3 small 1 cm incisions are performed in the patient's cavity, and the main purpose of the disposable laparoscopic trocar in laparoscopic surgery is to penetrate the abdominal wall Full-layer, establish a passage between the outside world and the abdominal cavity, allowing surgical instruments to enter the abdominal cavity through the trocar sleeve, completing the surgical process and achieving the same purpose as the traditional open surgery.
The disposable laparoscopic trocar is composed of a puncture sleeve and a puncture core. The main task of the puncture core is to penetrate the entire abdominal wall together with the trocar sleeve, leaving the puncture sleeve on
the abdominal wall. The main task of the puncture cannula is to allow various surgical instruments to pass into the abdominal cavity, so that the doctor can perform surgical operations and complete the surgical tasks.
The following editor will take you to learn more about the characteristics and advantages of disposable laparoscopic trocars.
Double-sided separation of puncture core head end
According to the statistical analysis of the report, many puncture hole complications are caused by infection, bleeding, puncture hole hernia and tissue damage. See the table below:
Table 1 Analysis of the causes of complications in the puncture hole after laparoscopic surgery
| project | Damage | Bleeding | Infect | Hernia | total |
| Improper selection of parts | 1 | 2 | 5 | 0 | 8 |
| Insufficient abdominal muscle relaxation | 2 | 1 | 0 | 0 | 3 |
| Blind puncture for the second operation | 2 | 0 | 0 | 0 | 2 |
| Incision contamination | 0 | 0 | 12 | 0 | 12 |
| Not tightly stitched | 0 | 1 | 3 | 3 | 7 |
| total | 5 | 7 | 20 | 3 | 35 |
Table 2 Relationship between puncture hole complications and puncture hole diameter after laparoscopic surgery
| project | Aperture 5mm | Aperture 11-15mm | Aperture >15mm |
| damage | 0 | 5 | 0 |
| Bleeding | 0 | 7 | 0 |
| Infect | 1 | 17 | 2 |
| hernia | 0 | 3 | 0 |
| total | 1 | 32 | 2 |
The core head of the disposable laparoscopic trocar is transparent and tapered. The blunt separation method without a knife is used to separate the tissue instead of cutting the tissue. When the trocar enters the abdominal wall, the puncture core pushes the tissue and blood vessels away along the tissue fibers. Limit damage to the abdominal wall and blood vessels. Compared with the trocar with a knife, it reduces fascia damage by about 40% and reduces the formation of puncture hole hernia by more than 80%. Through the endoscope, the entire process of abdominal wall puncture can be controlled directly to avoid damage to the abdominal tissue It can also save operation time and reduce surgical pain.
