Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As Figure 1-3, a kind of multi-angle puncture probe locator, including stepper motor 1 and it is arranged on stepper motor 1 one
The shaft coupling 3 at end, shaft coupling 3 are fixed on the one end of stepper motor 1 by screw 2, and the other end of shaft coupling 3 passes through the He of round nut 4
Hex nut 6 connects protective case 7, and the other end of protective case 7 is connected with supporting plate 8, and the bottom of supporting plate 8 is fixed with handle 10,
The both sides of handle 10 are respectively arranged with support frame 9, and the bottom of support frame 9 is fixed with universal wheel 12, and the both sides of protective case 7 are set respectively
Rolling guide 5 is equipped with, the inside of rolling guide 5 is fixed with rolling guide sliding block 18, and protective case 7 is internally provided with roller bearing screw mandrel
17, the middle part of roller bearing screw mandrel 17 is connected with feed screw nut 19, and the other end of feed screw nut 19 is fixed on axle by hex bolts 21
In bearing 22, the other end of roller bearing screw mandrel 17 is fixed on the deep groove ball bearing 14 in sleeve 13, and the top of sleeve 13 is fixed with
Stud 11, the end face of bearing block 22 are fixed with bearing (ball) cover 23, and the side of bearing (ball) cover 23 is provided with self-centering fixture 27,
The top of self-centering fixture 27 is provided with ball valve 26, and the both sides of ball valve 26 are provided with handle 25.
The outer cover of roller bearing screw mandrel 17 is equipped with sealing ring 15, and one end of sealing ring 15 is fixed with protective case flange 16.Roller bearing
The junction of screw mandrel 17 and bearing block 22 is provided with packing ring 20.The top of self-centering fixture 27, the company with rolling guide sliding block 18
The place of connecing is provided with spiral protective sheath 24.
Specifically, in use, in order that the locator can be easy to mobile and control, we employ the knot of universal wheel 12
Structure, in order to realize that X.Y motions can take the strap brake of universal wheel 12, it is allowed to 360 degree of rotations of horizontal direction, 8 wheels can be used.It is mobile
The locator is to before sick bed, when reaching desired position, it is possible to the brake of universal wheel 12 is stepped on, therefore can be locked by its, then
The position in locator X.Y directions determines that this is simple in construction, and easily operation, cost are also low, it is possible to achieve Expected Results.
Realize that lengthwise movement can use guide rail, motor driven ball-screw 17, the main function of ball-screw 17 is to be revolved
Transhipment is dynamic to be become to move along a straight line, and rolling movement is done due to many balls among ballscrew shaft and ball-screw nut be present,
Therefore the high transmission efficiency of comparison can be reached；With the features such as precision height, axial rigidity is high.Ball guide screw nat can be pre-
Pressure, but because precompression makes along the Variable between the direction of axle to negative value, so as to reach very strong rigidity.Due to
The locator disposably can not possibly move to accurate location, therefore also need to traverse feed, and traverse feed system is same
Using the structure as lengthwise movement structure, the horizontal movement on crossbeam is realized, it is reached defined location.
After position substantially is reached, the diseased region to be punctured is detected with probe, due to requiring that detection probe can be real
Existing 100~200 degree space is freely turned round, and in order to realize the requirement, probe is connected with sphere auxiliary structure and longitudinal motion mechanism
Connect, can easily realize the requirement.
Postponed when probe detects that diseased region positions really it is necessary to which its is locked., can be by tape spool when needing self-locking
Watt screw be screwed into, make probe self-locking, then the position that punctures determines.
After the position of probe determines, probe is removed, probe is changed, probe can be made with mould, so may be used
To be easy to feel relieved, and change and be convenient to.
After the position of above structure determines, then it can be accurately positioned.
This kind of multi-angle puncture probe locator, puncture technique can utilize the accurate action of the device, registration height, behaviour
The advantages that making to facilitate assisted surgery doctor carries out good operation technique, and success rate can significantly improve.Medical treatment can not only be mitigated
The fatigue of worker, and bigger progress is obtained in terms of the precision and security of raising operation.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
