Problems solved by technology

Although the natural orifice trans-luminal endoscopic surgery (NOTES) method does not require any incision, it is technically difficult, and surgical instruments need to pass through a long and narrow and complex human cavity before clamping and suturing, etc. surgical action
Most of the existing NOTES surgical mechanisms have many defects such as excessive volume and insufficient operational precision, and it is difficult to meet the technical requirements of endoscopic suture surgery, resulting in this type of device not being widely used clinically.

Abstract

The invention discloses a single-port laparoscopic imaging system for minimally invasive surgery. The system comprises an imaging terminal and a drive terminal. The imaging terminal comprises an imaging terminal head, an imaging terminal neck and a rotating mechanism. The imaging terminal neck can rotate around the imaging terminal head through a rotating mechanism. The imaging terminal neck is provided with a main lighting module. The imaging terminal head is provided with a camera module. The drive terminal comprises a flexible continuum mechanism and a drive terminal sleeve. The drive terminal is used for controlling the rotating mechanism to move and the flexible continuum mechanism to turn so that the imaging terminal head and the imaging terminal neck relatively rotate by a certain angle, and also adjusting the shooting angle of the imaging terminal so that the imaging terminal unfolds and adjusts in operating state. The imaging terminal and the drive terminal in the system are 12mm in maximum outside diameter, and the system can access the human body through a surgical sleeve just 12mm in diameter. The single-port laparoscopic imaging system for minimally invasive surgery is small in size, high in flexibility and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an imaging system for laparoscopic minimally invasive surgery. Background technique [0002] Minimally invasive surgery in the modern medical field has successfully reduced patients' postoperative pain, complications, hospital stay, and improved postoperative scar conditions. Although the natural orifice trans-luminal endoscopic surgery (NOTES) method does not require any incision, it is technically difficult, and surgical instruments need to pass through a long and narrow and complex human cavity before clamping and suturing, etc. surgical action. Most of the existing NOTES surgical mechanisms have many defects such as excessive volume and insufficient operational precision, and it is difficult to meet the technical requirements of endoscopic suture surgery, resulting in that this type of device has not been widely used clinically. Therefore, due to the unique adva...
