Graphene peritoneoscope and use method thereof

Abstract

The invention discloses a graphene peritoneoscope and a use method thereof. The graphene peritoneoscope comprises a mechanical rod connected with an external handle, wherein the mechanical rod is of asectional hollow structure, and comprises a front section rod, a first middle section rod, a second middle section rod and a rear section rod which have gradually increased diameters and are in telescopic sleeved connection with one another, and the front end of the front section rod is provided with a surgical instrument capable of stretching, contracting and swinging. The peritoneoscope has theadvantages that an operation can be performed under a CO2-free pneumoperitoneum condition, only one operative incision needs to be formed in the human body, and since a graphene material is used, sterilization and bacteriostasis can be effectively performed, and bacterial infection and inflammation of an operative site and operative incision are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a graphene laparoscope and a method for using the same. Background technique [0002] Laparoscope is an essential medical device in minimally invasive surgery. It can effectively help medical workers observe the condition of the surgical site and improve surgical accuracy by setting a miniature camera. However, existing laparoscopes still have the following defects: [0003] First, in laparoscopic surgery, CO 2 Pneumoperitoneum is the most common method of providing abdominal operating space, however, CO 2 Gas insufflation leads to increased intra-abdominal pressure and peritoneal CO 2 Absorption can induce a series of complications, such as hypercapnia, cardiopulmonary disease, venous stasis, gas embolism, thromboembolism and other serious complications. In addition, renal function, liver function, nerve conduction and systemic metabolism may also be disturbed. [00...

Problems solved by technology

[0003] First, in laparoscopic surgery, CO 2 Pneumoperitoneum is the most common method of providing abdominal operating space, however, CO 2 Gas insufflation leads to increased intra-abdominal pressure and peritoneal CO 2 A series of complications can be induced, such as hypercapnia, cardiopulmonary disease, venous stasis, gas embolism, thromboembolism and other serious complications. In addition, renal function, liver function, nerve conduction and systemic metabolism may also be disturbed.

[0004] Secondly, the existing laparoscopes need to open at least two surgical incisions in the human body, which affects the patient's recovery and postoperative aesthetics. Although some single-port laparoscopes have appeared, these single-port laparoscopes have complex structures, and the gap between the camera and surgical instruments Mutual interference between them makes the field of view obstructed, the operation is restricted, and the difficulty of the operation is increased.

[0005] Thirdly, a small amount of bacteria will inevitably be brought into the abdominal cavity of the human body during laparoscopic surgery, which is very likely to cause infection and inflammation of the surgical site and surgical incision, reducing the effectiveness of the operation
