Pickup robot in a kind of operation
Technical field
The present invention relates to medical instruments, in particular to pickup robot in a kind of operation.
Background technique
During surgery, medical worker takes object out of doctors and patients body, such as cotton balls, gauze, other internal fifth wheels, commonly use hand,
Tweezers, scissors, such tool is not easy and inconvenience exhausts internal fifth wheel completely, alternatively, internal fifth wheel is exhausted ratio completely
It is cumbersome.
Summary of the invention
Technical problem solved by the invention: the medical worker in operation is not easy or inconvenience is complete by fifth wheel in patient
It exhausts.
In order to solve the above technical problems, the invention provides the following technical scheme: pickup robot in a kind of operation, including bottom
Pedestal, the large arm being articulated on waist rotation member, the manipulator being mounted in large arm, is consolidated the waist rotation member being articulated on base body
The forearm being scheduled in large arm, the mechanical claw hand being mounted on forearm, waist rotation member are rotated around base body, and large arm turns around waist rotation member
It is dynamic;
The mechanical claw hand includes cleft hand rack, two pairs of cleft hands being hinged in cleft hand rack, is mounted in cleft hand rack
Cleft hand driving mechanism for driving two pairs of cleft hands to act;
The cleft hand driving mechanism includes support body, the first locking body, the second locking body;The support body is equipped with crank
Rocker Driving Mechanism, crank rocker driving gear include and the slide bar of cleft hand housing slide cooperation, first company hinged with slide bar
Bar and second connecting rod and the hinged telescopic rod of slide bar, crank and rocker mechanism;The first connecting rod and the first locking body are hinged, the
Two connecting rods and the second locking body are hinged, and the rocking bar in crank and rocker mechanism is hollow, and telescopic rod activity is plugged in rocking bar;Support body
It is equipped with the guide rod being oriented to the lifting of the first locking body and the second locking body;
Two cleft hands in first pair of cleft hand in two pairs of cleft hands are symmetrical set, second pair in two pairs of cleft hands
It is symmetrical arranged before and after two cleft hands in cleft hand, it is sliding that the bottom of two cleft hands in first pair of cleft hand opens up first be obliquely installed
The bottom of row slot, two cleft hands in second pair of cleft hand opens up the second slide slot being obliquely installed, the top of first locking body
Portion is equipped with the first sliding pin being slidably matched with the first slide slot, and the top of the second locking body is equipped with to be slidably matched with the second slide slot
The second sliding pin.
According to the above technical scheme, the working principle of pickup robot is as follows in a kind of operation of the present invention: first, medical matters
Personnel hold manipulation hand, rotate large arm or waist rotation member, are in the mechanical claw hand on forearm at item to get body;Second, crank
Rocking bar in rocker device is swung, and rocking bar is moved laterally by telescopic rod driving slider with respect to cleft hand rack, and first connecting rod drives
Dynamic first locking body decline, second connecting rod drive the second locking body to rise, and the first locking body drives the decline of the first sliding pin, due to the
One slide slot is obliquely installed, and therefore, the first sliding pin being vertically lowered can drive any cleft hand in first pair of cleft hand to surround itself and pawl
The hinged place of handset mounting rotates, in this way, first pair of cleft hand makees opposite swing;Meanwhile second locking body drive the second sliding pin rise,
Since the second slide slot is obliquely installed (the inclined direction of the second slide slot and the first slide slot are inclined contrary),
The second sliding pin risen vertically drives any cleft hand in second pair of cleft hand to rotate around the hinged place of itself and cleft hand rack, in this way,
Second pair of cleft hand makees opposite swing;So far, two pairs of cleft hands are in shape is collapsed, for grabbing object, at this point, rocking bar is rocked to left end
And rest on left end;Third, after object is removed doctors and patients' body by manipulator by medical worker, in crank and rocker mechanism
Rocking bar acts again, is rocked to right end from left end, driving slider makees reversed transverse shifting, the first lock of first connecting rod driving
Tight body rises, and second connecting rod drives the decline of the second locking body, and the first locking body drives the first sliding pin to rise, meanwhile, the second locking
Body drives the decline of the second sliding pin, and two pairs of cleft hands are in shape is actuated out, for discharging the object of crawl.
Through the above technical solutions, first pair of cleft hand connects the first locking body, second pair of cleft hand connects the second locking body, bent
Handle rocker device drives the first locking body and the second locking body to make reversed movement by first connecting rod and second connecting rod, makes first
To cleft hand and second pair of cleft hand moves at the same time and motion amplitude is identical, convenient for accurately and fully grabbing sufferer intrabody object.On
It states mechanical claw hand and cooperates rotatable waist rotation member and large arm, medical worker is facilitated to take object out of patient.
