Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of straight-line motion mechanism and trolley of performing the operation.
Background technique
As shown in figure 5, operation trolley includes pedestal 100, the rotary column 300 on pedestal 100, is set to rotary column
The structures such as the crossbeam of 300 upper ends and the manipulator 200 on crossbeam, the straight-line motion mechanism on rotary column rise for bearing
It is vertical to be passed to revolution by the weight for dropping body (lifting body is crossbeam and manipulator 200 in Fig. 5) for transverse bending moment from lifting body
Column, and drive lifting body to move up and down, while can require to stop at any time according to control in lifting process, and long-term, reliable
Ground is kept at the desired position.In order to realize better surgical procedure, it is desirable that the axial stroke of lifting body is long, and can be any
Position stops and locks, the driving method of preferred (ball) feed screw nut in numerous driving methods.
Currently, the mounting means of feed screw nut mainly has following three kinds: a, fixation-fixed；B, fixation-is supported；c,
Fixation-free style.For two kinds of mounting means of a and b, the pedestal at screw rod fixing end and support end requires to be mounted on fixed base
On plate, load is mounted on nut, is rotated by motor drives screw mandrel, and nut can drive load to make linear reciprocation fortune
Dynamic, in fixation-free style mounting means, the pedestal of screw rod fixing end is installed on substrate, and free end is hanging, load peace
It on nut, is rotated by motor drives screw mandrel, nut can drive load to make straight reciprocating motion.
For mounting means a and b, requires fixing end and the pedestal at end is supported to be mounted on fixed substrate, if
The ontology of load needs 1. to need to slot on load beyond end is supported, to avoid supporting the pedestal at end, but can weaken negative
The lateral rigidity of carrier；2. load is passed through connecting plate rigidity axially with the enough distances of screw rod axis parallel offset
Attaching nut and load, but screw rod will receive transverse bending moment, and the performance and safety to screw rod impact.For mounting means
C, although can satisfy the demand that load exceeds free end, this mounting means is suitable only for the fixing end of screw rod upper
The case where end, load exceed from lower end, the scope of application is small.
Rotary column on existing operation trolley is usually closed rectangle, circle or square, and inside does not accommodate zero
Component or not as the main structure for accommodating components, straight-line motion mechanism is generally located on the outer surface of rotary column, i.e.,
