Principle and Advantages of Using Endoscopic Linear Cutter Stapler

A linear cutting and stapling device includes a handle body, a pusher, a nail cartridge holder, and a staple holder. A push button for controlling the pusher is provided on the handle body. A cam with a hook portion is rotationally connected to the handle body. The cam's side is equipped with a safety mechanism. When the safety mechanism is in the locked state, the hook portion hooks on the push button, and the cam is fixed relative to the handle body. When the safety mechanism is in the unlocked state, the hook portion releases the push button.

Advantages of the endoscopic linear cutter stapler

The endoscopic linear cutter stapler is now widely used in anal and rectal surgeries and has significant advantages over manual anastomosis.

  • The device can complete some anastomoses that are difficult to accomplish manually, as well as anastomoses for low rectal cancer.

  • It shortens operation time, reduces trauma from long-term surgery and anesthesia, reduces the impact on organs such as the heart, lungs, liver, and kidneys, and increases operative safety.

  • The quality of the anastomosis produced by the device is high, with a smooth and neat inner wall, tightly and reliably stapled rows on both sides of the anastomosis, better blood supply to the anastomosis, and lower complications than the traditional double-line suturing method.

  • This type of medical stapler is suitable for both open and laparoscopic surgery.

  • The anastomotic material used by the device is metal staples, which are tissue-compatible and cause less inflammation than foreign body stimulation, making it easier for the anastomosis to heal. Selecting the appropriate height of the nail cartridge and the diameter of the anastomotic tube according to the thickness of the tissue and the diameter of the anastomosis, mastering the characteristics of the tissue and the principles of anastomosis, and grasping the key points of anastomosis are critical to successful anastomosis. The endoscopic linear cutter stapler can be used in open or laparoscopic surgery.

  • Although the linear cutter price may be high compared to other surgical tools, its advantages make it a cost-effective option in the long run, as it reduces the need for blood transfusions and compensatory interventions. In summary, the endoscopic linear cutter stapler is a valuable surgical tool that offers numerous benefits to patients and surgeons alike.

Operating principle of the endoscopic linear cutter stapler

  • Select and use a nail cartridge that matches the thickness of the tissue.

  • Effective pre-compression. Clamp and wait for 15 seconds, then tap the instrument to remove tissue fluid and reduce tissue thickness, while fully protecting the mucosa and submucosa of the anastomotic tissue.

  • The tapping should be stable, ensuring the stability of the endoscopic linear cutter stapler during tapping and preventing traction.

  • When there is bleeding or oozing from the anastomosis, the energy device should be used cautiously to prevent additional damage.

  • Precautionary reinforcement. After tapping, observe the condition of the anastomotic line, especially where the suture lines overlap. If necessary, use a suture to reinforce the full muscle layer or multi-layer suture.
