Embodiment

[0032] see figure 1 and figure 2 , the tissue magnetic retraction and suspension device for laparoscopy in the illustration is a preferred solution of the present invention, specifically including an external magnet 5 and an internal suction cup 16 and a retraction suspension assembly that are sent into the body through the laparoscope, and the internal suction cup 16 is magnetically fixed with the external magnet 5 through the skin layer tissue, and the external magnet 5 is tensioned and set by the winding system installed outside the body, and the retraction suspension component is connected with the internal suction cup 16, and the external magnet 5 and the internal suction cup are fixed by magnetic attraction 16. The organs and tissues in the body are retracted and suspended.

[0033] Wherein, the external magnet 5 is supported on the operating table 9 by a winding system composed of the external wire take-up device 3, the external pull wire 4, the front section support ...

Embodiment 2

[0044] see Figure 5 and Figure 6 , the retraction suspension assembly of the present embodiment includes a connecting line 14 and two sets of fixing hooks 15 connected to the two ends of the connecting line 14, the connecting line 14 bypasses the bottom of the organ tissue to be displaced, and the two sets of fixing hooks 15 are connected with the two sets of fixing hooks respectively. The internal sucker 16 is articulated, and the organ tissue is suspended by two sets of external magnets 5 .

[0045] During operation, after the two groups of suction cups 16 in the body are retracted and the suspension assembly is sent into the body through a laparoscopic channel, the two groups of suction cups 16 in the body are respectively fixed on the inner side of the skin layer tissue 17 in an open state through laparoscopic instruments, and the external magnets 5. Through the skin layer tissue 17 to absorb the suction cup in the body to complete the fixation, use other laparoscopic i...

Abstract

The invention discloses a tissue magnetic attraction traction suspending device for a laparoscope. The tissue magnetic attraction traction suspending device includes an in vitro magnet, an in vivo sucker and a traction suspension assembly, wherein the in vivo sucker and the traction suspension assembly are sent in vivo through the laparoscope. The in vivo sucker is fixed to the in vitro magnet ina magnetic attraction mode through a skin layer tissue, the in vitro magnet is tensioned through a winding system arranged in vitro, the traction suspension assembly is connected with the in vivo sucker, and in vivo organs and tissues undergo traction and suspending through the vitro magnet and the in vivo sucker which are fixed by magnetic attraction. The tissue magnetic attraction traction suspending device is ingenious in structural design and reasonable in structure, discrete metal particles serve as magnetic receiving bodies of the in vivo sucker, the volume of the magnet capable of beingin vivo and the magnetic field action area are effectively increased, magnetic attraction of internal and external structures is enhanced, and the feasibility of the internal and external structuresduring concrete implementation is enhanced. A relatively large traction force can be provided by an electromagnetic attraction force, and through electromagnet control and adjustable output power of an energy supply device, the needs of different operations can be met.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a tissue retraction suspension device, in particular to a tissue magnetic retraction suspension device for laparoscopy. Background technique [0002] With the development of medical technology, endoscopic surgery, as a new type of surgery, is more and more favored by doctors and patients, and has the advantages of small surgical wounds. Due to the different surgical sites during the operation, other organs need to be temporarily displaced to expose the field of view required for the operation. In the prior art, the operation is performed through tissue retraction and suspension. It mainly includes the following two options: [0003] The first solution is to use both ends of the clamping instrument, one end is clamped on the organ tissue that needs to be displaced, and the other end is clamped on the inner wall of the abdominal cavity. The supporting force required for traction of the organs is...
