A medical system for direct tissue repair and shaping in the body

Abstract

Disclosed are a medical system for directly repairing and forming an in vivo tissue and a repair method thereof, wherein the medical system comprises a support platform, an imaging unit, an execution unit, a forming unit and a control unit. According to the information acquired by the imaging unit in real time, the control unit is manipulated to drive the execution unit comprising three mechanical arms with six degrees of freedom and an execution instrument at an end portion thereof to operate, thus excising a diseased tissue and repairing and forming a new tissue. The present invention is based on the minimally invasive surgery and tissue forming principle, wherein first, a diseased tissue to be excised is excised and sucked out from the body; then, a macromolecular solution containing cells is sprayed at a set position to form a cell layer; and finally, a macromolecular solution is sprayed outside the cell layer to form a protective film. The tissue repair and forming is performed following the set steps. The present invention causes less trauma for a patient, and can achieve the accurate positioning of multiple materials and multiple cells at a position in the body, thus rapidly repairing a diseased tissue in vivo and restoring the tissue function thereof.

Description

technical field [0001] The invention relates to a medical system used in a patient's body, in particular to a medical system for directly repairing and shaping tissues in the body and a repairing method thereof. technical field [0002] The invention relates to a medical system used in a patient's body, and belongs to the technical field of medical equipment. Background technique [0003] Large pieces of soft tissue and internal organs (such as heart, liver, spleen, lung, kidney, etc.) are important components of the human body. Due to related damage and dysfunction caused by disease, trauma and aging, they seriously endanger human health and quality of life. Traditional surgery requires the use of instruments such as knives, scissors, and needles to operate on parts of the human body. It is the main treatment method of surgery, commonly known as "surgery". The purpose is to treat or diagnose diseases, such as removing diseased tissue, repairing damage, transplanting orga...

AI Technical Summary

Problems solved by technology

[0004] 1) Large wound: the traditional long incision is ≥10cm, and the scar is long and linear, which affects the appearance;

[0005] 2) Great pain: Traditional surgery requires laparotomy, and the incision site is often accompanied by pain, soreness, and numbness after surgery;

[0006] 3) Slow recovery: Due to the large incision in traditional surgery, it will cause damage to muscles, blood vessels and corresponding nerves near the incision, which may be accompanied by some tissue infection complications, so the recovery speed of patients is slow

[0007] 4) Long hospital stay: get out of bed 24 hours after surgery, and leave the hospital in 7-15 days, the cost is relatively high

[0008] 5) Much bleeding: the traditional surgery separates the tissue extensively, and the amount of bleeding is relatively large

[0012] ①The function is not perfect. Generally, after necrosis of tissue lesions needs to be removed, cell printing, tissue repair and restoration of its proper functions are also required.

③The degree of freedom is low, and the six-degree-of-freedom operating device can effectively simulate the movement of the human arm to ensure the smooth and efficient completion of the operation
