What is laparoscope?
One of the minimally invasive surgery instruments is laparoscope. This device has three main part:
- Vision system
- Light system
- Insufflation system:
Vision system: it has four parts: lens, lens cable, film processor and monitor.
Lens is a rod with 34 to 44 cm length and 3 or 5 or 10 mm diameter and designs to take film. Data is transferred via lens cable to the processor and then processed film is shown by the monitor. In this method the film has very good quality and 15 to 20 times more magnification so the laparoscopic and minimally invasive surgeon has much better view and access, so the surgery proceeds in a nice manner.
Vision is completed by the light because the abdominal cavity is dark by its own, so this light will be emitted by xenon or LED lamps via a fiber optic cable.
Carbon dioxide is an inert and safe gas for our body so we use it to insufflate the abdomen to separate the abdominal wall away from its contents and get the better view. After ending the operation all of gas is evacuated or resorbs and cleaned via respiratory work.
It’s a type of minimally invasive surgery performed by a specialized robot. The basic concept is just like laparoscopic surgery but the patients are not connected physically and the surgeon may be sited in another room to conduct the robot. These operations are so expensive and not widely applicable. There is no robot in Iran just now but with negotiations it may be available soon.
As its name informs this type of surgery is performed with minimal invasion and less damage to human tissue. Primarily skin and underlying tissues are cut with small and minimal incisions about 5 to 10 mm instead of large incisions in open surgeries. In another next step internal organs are manipulated much less than open counterpart so the patients has no damage to these organs. In post-operative period he or she experience lower pain. Due to less invasion patients return to work and normal daily activity earlier. It is important to note that minimally invasive surgeries have more primary costs due to expensive instruments but due to earlier discharge and return to work, these type of operation is financially beneficial.
benefits: less invasion and damage to patients’ tissue, less pain and earlier return to work and routine life activity
problems: primary higher costs due to expensive instruments costs, performing laparoscopic surgery by none-professional surgeons
