Example Embodiment

[0159]Such asFigures 1 to 36 As shown, the present embodiment provides a moving mechanism of minimally invasive surgery, including a plurality of joints, and hinged between adjacent two joints.

[0160]Various improvements as this embodiment will be detailed below.

[0161]Such asfigure 1 ,figure 2 ,Figure 6 withFigure 29 Distance

[0162]A damping torsion spring 8 is provided between the two adjacent joints.

[0163]The damping torsion spring 8 is set on the hinge shaft 7.

[0164]Two of the damping towers 8 are attached to each of the hinge shafts 7.

[0165]The two of the two of the damping towers are mounted.

[0166]The adjacent two joints are pressed between the damping towers 8.

[0167]In two end faces opposite adjacent two joints, one of the end faces is provided with two outer articulated ear, and the end surface is provided with two inner articulated ear.

[0168]The three of the outer hinged hinges are blind holes or through holes.

[0169]The hinged holes of the two outer hinges are located on the s...

Abstract

The invention discloses a movement mechanism of a minimally invasive surgery medical device and the minimally invasive surgery medical device. The movement mechanism comprises a plurality of joints and every two adjacent joints are hinged through a hinged shaft; a damping torsional spring is arranged between every two adjacent joints; the damping torsion springs sleeve the hinged shaft; each hinged shaft is sleeved with two damping torsional springs; mounting directions of the two damping torsion springs are opposite; every two adjacent joints are connected with the damping torsion springs in a press fit manner; in two opposite end faces of the two adjacent joints, one end face is provided with two outer side hinge lugs, and the other end face is provided with two inner side hinge lugs; and the two damping torsion springs on the same hinged shaft are respectively arranged between two pairs of the adjacent outer side hinge lugs and inner side hinge lugs. A problem that the joints are disjointed in an operation process is not prone to occurring, movement instability between every two adjacent joints can be effectively prevented, and safety of operation is greatly improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a movement mechanism of a minimally invasive surgical medical device and the minimally invasive surgical medical device. Background technique [0002] Minimally invasive surgery refers to the surgical operation performed by doctors using modern medical instruments such as laparoscopy and thoracoscopy, as well as related equipment. Minimally invasive surgery technology is known as one of the important contributions of the medical field to human civilization in the 20th century. It is the development of global surgery in the 21st century. the main theme. Compared with traditional open surgery, minimally invasive surgery has the advantages of small incision, less blood loss, short recovery time, and small postoperative scar, and is more and more widely used in clinical operations. [0003] On July 07, 2017, the Patent Office of the State Intellectual Property Office of the People's Republic of C...
