, and realize the Micro trauma of patient, lose blood less, the purpose that postoperative infection is few, post-operative recovery is fast, the medical machine for operation
People's system is usually using master-slave mode mechanical arm.Operator is to main hand mechanical arm（Main operation manipulator）When being operated, hand
Athletic meeting drives main operation manipulator to move therewith, and each joint of main operation manipulator is mainly passive movement, so as to measure
To the movable information of joint, then by master ＆ slave control algorithm by the Motion mapping of main manipulator to from manipulator, so as to
Driving realizes corresponding sports from manipulator.
Operate main hand for example, Chinese patent discloses a kind of micro-wound operation robot seven freedom [application publication number is
CN106667583A], including pedestal, the rotating disk for being arranged on pedestal and being rotated around z-axis, being rotated around x-axis of being connected with rotating disk
Connecting rod, being rotated around the No.1 rotation connecting rod that x-axis rotates, with what No.1 rotation connecting rod was connected around x-axis of being connected with connecting rod
No. two rotation connecting rods and connected clamping device, clamping device include the thumb component and forefinger part that rotate against,
By setting four bugle displacement transducers to measure the angle that forefinger part turns over relative to thumb component in real time.
Above-mentioned clamping device, although the angle that forefinger part turns over relative to thumb component can be measured in real time, its according to
So problems be present：1st, clamping device can not produce displacement in the axial direction, and the free degree is low；2nd, when forefinger part is relative to thumb
It can not be automatically reset after part rotation, need hand-reset after each end of operation, efficiency is low；3rd, clamping device is Passive part,
The action of finger can only be followed and moved, it is impossible to realize positive action.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of achievable positive action
Seven freedom main operation manipulator hand-held mechanism.
The purpose of this utility model can be realized by following technical proposal：
The hand-held mechanism of this seven freedom main operation manipulator, including bearing and be arranged in bearing can be around own central axis
The rotating shaft of line rotation, the outer end of the rotating shaft are hinged with two tongs being oppositely arranged, it is characterised in that the outer end of the rotating shaft
With being symmetrically hinged on along its axially extending fluting, two tongs in fluting, described rotating shaft, which is provided with, to be used to limit two tongs
The limit assembly of angle is outwards rotated up to, is provided between the tong described in two after tong is to internal rotation and is used to answer two tongs
The resetting structure of position.
In the hand-held mechanism of above-mentioned seven freedom main operation manipulator, described limit assembly includes being fixed on rotating shaft

Drift angle, drift angle is resisted against on end cap after tong outwards rotates to an angle.
In the hand-held mechanism of above-mentioned seven freedom main operation manipulator, described resetting structure includes same be located in and turned
Positioning hole in axle, the push rod being arranged in positioning hole and the spring between push rod and bottom, one end of the push rod are same
When act on two tongs.
One end of spring is resisted against the bottom of positioning hole, and its other end is acted on push rod, in the presence of spring force,
One end of push rod is promoted to be resisted against simultaneously on the inner side of two tongs.When two tongs simultaneously to internal rotation when, tong pressure-ram, make
Push rod produces axial movement, and spring is compressed, and when acting on the disappearance of the chucking power on tong, spring reset, drives two tongs
Reset, until the drift angle of two tongs is abutted on end cap.
In the hand-held mechanism of above-mentioned seven freedom main operation manipulator, described push rod is cut with scissors close to one end of two tongs
Bearing one is connected to, described bearing one is in rolling contact with the medial surface of two tongs simultaneously.
Accurate displacement is provided with the hand-held mechanism of above-mentioned seven freedom main operation manipulator, in described bearing to sense
Device, its internal diameter being coaxially disposed in described rotating shaft are less than the pilot hole of positioning hole internal diameter, cunning are equipped with described pilot hole
Lever, one end and the push rod of the sliding bar are connected, and the other end of the sliding bar is connected with precise displacement sensor.
Have in the hand-held mechanism of above-mentioned seven freedom main operation manipulator, in described bearing and axially prolong along rotating shaft
The horizontal chamber stretched and the vertical chamber connected with horizontal chamber, described rotating shaft are located in horizontal intracavitary, and described vertical intracavitary is provided with when rotating shaft rotates
It is used for the reset assembly for resetting rotating shaft afterwards.
In the hand-held mechanism of above-mentioned seven freedom main operation manipulator, described reset assembly is included located at vertical intracavitary
Motor, the rear end of the rotating shaft is provided with bevel gear one, and the output shaft of the motor is provided with bevel gear two, bevel gear one and cone
Gear two engages.
In the hand-held mechanism of above-mentioned seven freedom main operation manipulator, described motor, which is provided with, to be used to measure its turn
The encoder of the axle anglec of rotation.
It is provided with and is located in the hand-held mechanism of above-mentioned seven freedom main operation manipulator, between described rotating shaft and bearing
The bearing two of horizontal intracavitary.
When applying chucking power on two tongs, tong promotes bearing one to move, so as to promote push rod and sliding bar to do branch line
Motion, spring produce resistance, while the distance moved by precise displacement sensor record sliding bar to the pressing action of tong,
The swing angle of tong can be learnt by corresponding geometric transformation；When chucking power removes, spring promotes push rod resilience, band moving axis
A resilience is held, bearing one is acted on two tongs simultaneously makes its opening, it is known that untill the drift angle of tong abuts to end cap.If rotating shaft
Rotate, then two tongs can be driven to rotate together, band dynamic bevel gear one rotates when rotating shaft rotates, and bevel gear one is with mantle tooth
The rotation of wheel two, so as to which drive motor rotating shaft rotates, the angle that machine shaft rotated can record by encoder；Turn when acting on
When revolving force on axle removes, motor rotates as active force band dynamic bevel gear two, so as to be rotated with dynamic bevel gear one and rotating shaft,
Now machine shaft is oppositely oriented, and angle of revolution is the angle of encoder record.
When motor works, rotating shaft can be driven to carry out active rotation, so as to realize positive action.
Compared with prior art, the hand-held mechanism of this seven freedom main operation manipulator has advantages below：By tong
Swing angle is converted into linear motion, so that by measuring indirect measurement of the straight-line displacement realization to tong swing angle, simultaneously
The indirect measurement of the countershaft anglec of rotation is realized using encoder, it is convenient and accurate to measure；After rotation, resetting structure can be passed through
Resetted with reset assembly, automaticity is high；Rotating shaft can both move along a straight line, and can also rotate, and the free degree is high, be applicable model
Enclose wide；Positive action, automaticity height can be realized.
