Embodiment Construction

[0013] The present invention will be further described in detail in conjunction with specific embodiments and accompanying drawings.

[0014] See first figure 1 The perspective view of the present invention shows that the hollow-shaped transmission member 1 for a multi-degree-of-freedom transmission mechanism is installed in the transmission mechanism of a minimally invasive surgical instrument for transmitting surgical operation force and torque. The hollow-shaped transmission part 1 is a round tube, and its two ends are end portions 12 for connecting the handle of the surgical instrument and the actuator brake mechanism. The end portion 12 is a hollow cylinder in this embodiment, and may also be a solid Cylinder; the middle of the hollow-shaped transmission part 1 is a hollow part 11, please refer to figure 2 , the hollow part 11 is provided with a plurality of through holes 111 penetrating through the tube wall of the round tube, and the shape of the through holes 111 can...

Abstract

The invention discloses a hollowed-out transmission part for a multi degree of freedom (DOF) transmission mechanism, characterized in that: the hollowed-out transmission part is a circular pipe, two ends of the circular pipe are end portions, the end portions are solid circular columns or hollow circular columns, the middle portion of the hollowed-out transmission part is a hollow out portion, the hollow out portion is provided with a plurality of through holes which break through the pipe wall of the circular pipe, and the through holes are rhomboic or rectangular. According to the invention, the hollowed-out transmission part is a half-rigid member having a certain flexibility, can transmit enough operation operating physical force and torque and can realize bending, and can guarantee the multi DOF and agility of surgical equipment operation. The hollowed-out transmission part for the multi DOF transmission mechanism has a simple structure, can be easily cleaned and disinfected, and can be reused. The hollowed-out transmission part for the multi DOF transmission mechanism is suitable for transmission mechanisms of minimally invasive minimally invasive surgical operation equipments.

Description

technical field [0001] The invention relates to the field of minimally invasive medical instruments, in particular to a hollow-shaped transmission member used in a multi-degree-of-freedom transmission mechanism in minimally invasive surgical instruments. Background technique [0002] The minimally invasive surgery (Minimally Invasive Surgery, MIS) technology field is at the forefront of today's medical technology development direction. Minimally invasive surgery represented by Laparoscopic Surgery (LS) has gradually replaced traditional laparotomy. After more than 20 years of development, laparoscopic minimally invasive surgery technology has gradually matured. It has been widely used and satisfied in clinical practice due to its characteristics of small surgical trauma, mild postoperative pain, short hospital stay, and good cosmetic effect. Effect. Conventional laparoscopic surgery is accomplished through multiple (3-5) tiny incisions (about 5-12mm). With the enrichment of...
