Magnetic control intra-lumen tissue tractor

Abstract

The invention relates to a magnetic control intra-lumen tissue tractor, which comprises a tissue holder for clamping tissues in a lumen and a motion controller which is arranged outside the lumen andgets into magnetic-attraction matching with the tissue holder, and further comprises a holder accommodating controller, wherein the motion controller, when moving outside the lumen, can control the position status of the tissue holder in the lumen, so that tissues, which are held, can be clamped and drawn via the tissue holder; the tissue holder can be accommodated via the holder accommodating controller, and via the holder accommodating controller, the tissue holder can be pushed into the lumen and tissues, which are required in the lumen, can be clamped; and the tissue holder is released andkept in the lumen via the holder accommodating controller after the tissue holder enters the lumen to clamp the tissues. The tissue tractor provided by the invention is compact in structure; intra-lumen traction and in-vitro traction of the tissues can be conducted, so that space occupation of the intra-lumen traction can be diminished, a space can be saved, trauma caused by traction can be relieved and requirements on operating personnel can be reduced; and the tissue tractor is convenient to use.

Description

technical field [0001] The invention relates to a retractor, in particular to a magnetically controlled intracavity tissue retractor, which belongs to the technical field of medical instruments. Background technique [0002] In minimally invasive surgery such as laparoscopic surgery or endoscopic surgery, since the surgeon's hand cannot enter the patient's body cavity, the body tissue that needs to be operated on is subject to self-suspended tissue, partially cut free tissue or internal organs (such as liver, spleen) When covering, these organs must be turned to expose the surgical operation site and continue the surgical process. [0003] At present, when laparoscopic surgery is used to stretch the tissue to expose the surgical site, the method used is to make an additional puncture incision and place a long-rod surgical forceps for stretching and exposure. The long-rod surgical forceps occupy the operating space and affect the operation of the surgeon. At the same time, T...

Problems solved by technology

[0003] At present, when laparoscopic surgery is used to stretch the tissue to expose the surgical site, the method used is to make an additional puncture incision and place a long-rod surgical forceps for stretching and exposure. The long-rod surgical forceps occupy the operating space and affect the operation of the surgeon. At the same time, The puncture incision will increase the trauma and pain of the patient, and increase the scar on the patient's body surface and affect the appearance

[0004] There is no safe and effective pulling exposure method in endoscopic surgery, and the extremely ineffective body position reversal or insertion of surgical wires is often used to pull through the mouth or anus, which greatly affects the operation process, not only increases the operation cost, but also increases the risk of surgery for patients , needs improvement
