When it comes to laparoscopic surgery, people are no stranger. It is usually operated in the patient's cavity through 2-3 small incisions of 1 cm. The main purpose of disposable laparoscopic puncture device in laparoscopic surgery is to penetrate the whole layer of abdominal wall, establish a channel between the outside and the abdominal cavity, let the surgical instruments enter the abdominal cavity through the puncture device sleeve, complete the surgical process and achieve the same purpose of traditional open surgery.
The disposable laparoscopic puncture device consists of a puncture sleeve and a puncture core. The main task of the puncture core is to penetrate the whole process of the abdominal wall together with the puncture sleeve and leave the puncture sleeve on the abdominal wall. The main task of puncture cannula is to let all kinds of surgical instruments enter the abdominal cavity. Doctors can perform surgical operations and complete surgical tasks.
Detailed understanding of the characteristics and advantages of disposable laparoscopic puncture device
Double sided separation of puncture core end
According to the statistical analysis of the report, many puncture hole complications are caused by infection, bleeding, puncture hole hernia and tissue injury. See the following table:
The core head of the puncture device for disposable laparoscopy is transparent and conical, and the knife free blunt separation method is adopted to replace the cut tissue with the separated tissue. When the puncture device enters the abdominal wall, the puncture core pushes the tissue and blood vessels away along the tissue fibers to minimize the damage to the abdominal wall and blood vessels. Compared with the puncture device with knife, it reduces about 40% of fascia damage and more than 80% of the formation of puncture hole hernia. The whole process of abdominal wall puncture can be directly controlled through endoscope, It can avoid damaging abdominal tissue, save operation time and reduce operation pain.
External barb thread of sheath
The external barbed thread is adopted on the sheath surface of the puncture device for disposable secondary laparoscopy to increase the fixation of the abdominal wall. When the puncture core is pulled out, the strength is increased, which can improve the fixation of the abdominal wall by about 90%.
45 ° inclined opening at sheath head
The head end of the sheath tube of the disposable laparoscopic puncture device is opened in a 45 ° inclined plane, which is convenient for the specimen to enter the sheath tube and leaves space for the operation of the instrument.
Complete models and specifications
There are many specifications of disposable puncture device for secondary laparoscopy: inner diameter 5.5mm, 10.5mm, 12.5mm, etc.
In a word, disposable laparoscopic puncture device can reduce the amount of bleeding in laparoscopic minimally invasive surgery, make patients recover faster, shorten the operation time, and make patients become the beneficiaries of minimally invasive abdominal surgery.
