Embodiment Construction

[0159] Such as Figure 1 to Figure 36 As shown, this embodiment provides a movement mechanism of a medical instrument for minimally invasive surgery, which includes a plurality of joints, and two adjacent joints are hinged by a hinge shaft 7 .

[0160] Various improvements of this embodiment are described in detail below.

[0161] Such as figure 1 , figure 2 , Figure 6 and Figure 29 as shown,

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

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

[0164] Two damping torsion springs 8 are sheathed on each hinge shaft 7 .

[0165] The directions in which the two damping torsion springs 8 are installed are opposite.

[0166] Two adjacent joints are press-fit connected with the damping torsion spring 8 .

[0167] Among the two opposite end surfaces of two adjacent joints, one of the end surfaces is provided with two outer hinge ears, and the other end surface is provided with...

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...
