Description

Liquid-absorbing magnetic blood vessel stapler for thoracic surgery

technical field

The invention relates to the technical field of thoracic surgery instruments, in particular to a liquid-absorbing magnetic blood vessel stapler for thoracic surgery.

Background technique

Vascular anastomosis technology began more than one hundred years ago with the application of manual sutures such as Carrel, A, (1908) and Hopfnet, E, (1903) for vascular grafting and replantation of amputated limbs. After more than one hundred years of development, this The technology has been widely used in various surgical procedures. The basic working principle of the stapler is to clamp the tissue by closing the two corresponding handle components (usually including the anvil base component and the staple cartridge component), and then push the staples in the staple cartridge component into shape to suture the tissue together. In some staplers, a cutting knife is also installed to cut off the stitched tissue.

According to the above, the vascular stapler currently used in clinical thoracic surgery has many defects and deficiencies due to its traditional structure and single function, as follows;

1. The traditional vascular stapler cannot quickly butt the two blood vessels at the far end at a close distance. It requires multiple medical staff to operate surgical forceps to clamp the blood vessels for closer butt joint, so it is not only time-consuming and laborious. In addition, due to the operation of more surgical instruments, it also greatly increases the difficulty of surgery.

2. In the traditional way, because the blood vessels are clamped by manually operated surgical forceps, the stability is poor, and the blood vessels cannot be effectively fixed before the complete anastomosis, and problems such as slipping and loosening are prone to occur.

3. During the operation, if the fluid in the patient's body accumulates, if it is not treated, it will easily interfere with the normal operation. The current clinical practice generally uses a drainage tube for drainage, but this also increases the number of instruments and further compresses the patient's body. Operating space, disguised interference and aggravated the difficulty of surgery.

Therefore in view of the above defects, it is necessary to design a liquid-absorbing magnetic blood vessel stapler for thoracic surgery.
