A magnetically anchored laparoscopy system based on near-infrared light visual diagnosis

Abstract

The invention provides a magnetic anchoring laparoscope system based on near-infrared light vision diagnosis. The magnetic anchoring laparoscope system comprises a dual-light-source magnetic anchoring laparoscope, an in-vitro magnetic unit, a hydraulic button and an in-vitro working station, wherein an inner magnet, a white light LED, a near-infrared light LED, a CCD camera and hydraulic biopsy forceps are arranged in the dual-light-source magnetic anchoring laparoscope, the hydraulic biopsy forceps comprise a first hydraulic cavity and elastic biopsy forceps, forceps heads extend out of the dual-light-source magnetic anchoring laparoscope, the in-vitro magnetic unit is matched with the inner magnet to locate the dual-light-source magnetic anchoring laparoscope, the hydraulic button is arranged externally, and connected with the hydraulic biopsy forceps through a hydraulic line to control opening and closing of the forceps heads, and the in-vitro working station comprises a displayer and a processor and is connected with the white light LED, the near-infrared light LED and the CCD camera through data lines. The laparoscope, the magnetic anchoring technology and the near-infrared light tumor developing technology are combined, the size is small, a magnetic anchoring mode is adopted for locating, a traditional laparoscope can be used for trocar, during an operation, the trocar space is not occupied, and under the condition of using the single traditional laparoscope for trocar, liver tumor probing and biopsy obtaining can be completed.

Description

technical field [0001] The invention belongs to the technical field of medical equipment laparoscopy, in particular to a magnetic anchoring laparoscopy system based on near-infrared light visual diagnosis. Background technique [0002] The laparoscopic technology that emerged in the 1990s brought surgery into the era of minimally invasive surgery. Taking cholecystectomy as an example, traditional open surgery requires an incision of about 15 cm, while laparoscopic surgery only requires 3-4 pokes with a diameter of 5-10 mm. The card can be completed by inserting the laparoscope, pulling instruments and cutting instruments. On this basis, surgeons have been exploring more minimally invasive surgical methods, so that patients can obtain maximum benefits with minimum trauma. The transumbilical single-port laparoscopic surgery (LESS) developed in recent years is the result of surgeons' pursuit of ultra-minimally invasive surgery. In single-port laparoscopic surgery, since the l...

Problems solved by technology

In addition, the current laparoscope only has lighting and camera functions, and cannot provide more information for the diagnosis of liver tumors, so the exploration and biopsy of liver tumors often need to be performed under laparotomy conditions, which greatly increases the trauma of patients
