Description
Technical field
The utility model relates to a kind of rotating shaft cylinder locking device, particularly relates to the rotating shaft cylinder locking device of a kind of oral cavity dentistry operation microscope joint arm.
Background technique
The microscopical joint arm of operation on oral cavity, in the time turning to microscope alignment lens patient focus, make it maintain static at present, needs rotation to stop the rotating shaft on tight handwheel locking joint arm, prevents microscopical movement.So operative doctor is being adjusted after surgery location, the surgery location of must standing up to leave, needs screwing and stop tight handwheel (have four-five on an operation microscope and stop tight handwheel) on joint arm one by one.If doctor need change surgery location or patient tells the rinse water in mouth, all can cause microscope to depart from patient's focus, so doctor must repeat again above set-up procedure, more difficult and trouble operates.If without handwheel locking rotating shaft, as long as touch a little a little, microscope will depart from patient's focus, operation just cannot be carried out.In the time carrying out oral cavity or dentistry micrurgy, need to lock the rotating shaft of each joint arm, otherwise operation microscope is difficult for aligning patient focus, easily produces deviation, cannot perform the operation.While carrying out now oral cavity or dentistry micrurgy, be all that operation microscope is aimed to patient's affected area, and then screw one by one the tight handwheel that stops of rotating shaft on joint arm, to prevent microscopical movement.The shortcoming of prior art is as follows: one, and operative doctor is adjusting joint arm while making microscope alignment patient focus, can not go to screw to stop tight handwheel simultaneously.In the time that doctor stands up to screw handwheel, microscope position can produce again deviation.Two, in the time carrying out operation on oral cavity, patient can be frequent tell watery blood and the rinse water of in mouth, overflowing, therefore, otherwise open close mistake is adjusted microscope on joint arm and aims at patient's affected area, and doctor just must constantly carry out unclamping and screwing of handwheel, operates so pretty troublesome, time is long, and efficiency is low.Three, if doctor is by microscope alignment patient affected area, does not screw and stop tight handwheel, in surgical procedure, as long as a little touch joint arm, microscope will depart from patient's affected area, causes operation to carry out.
Summary of the invention
Technical problem to be solved in the utility model is to provide the rotating shaft cylinder locking device of a kind of oral cavity dentistry operation microscope joint arm, its registration, and easy-to-operat, raises the efficiency, and operation is carried out smoothly.
The utility model solves above-mentioned technical problem by following technical proposals: the rotating shaft cylinder locking device of a kind of oral cavity dentistry operation microscope joint arm, it is characterized in that, it comprises joint arm axle sleeve, suction tude, solenoid valve, bearing, rotating shaft, clamp ring, and cap, thimble, pneumatic tube, the first cylinder, the second cylinder, the 3rd cylinder, four-cylinder, the 5th cylinder, the 6th cylinder, pneumatic control switch, joint arm axle sleeve by bearing housing in rotating shaft, rotating shaft is between bearing and clamp ring, suction tude is connected with solenoid valve, and cap is positioned at the top of clamp ring, the first cylinder, the second cylinder, the 3rd cylinder, four-cylinder, the 5th cylinder, the 6th cylinder is all connected with solenoid valve by pneumatic tube, the first cylinder is connected with thimble, pneumatic control switch is connected with solenoid valve.
Preferably, described joint arm axle sleeve, bearing are all positioned on a column.
Preferably, described solenoid valve is positioned on a crossbeam, between the second cylinder, the 3rd cylinder, four-cylinder, the 5th cylinder, the 6th cylinder, connects by a link arm.
Positive progressive effect of the present utility model is: one, and by pneumatic control switch, rotating shafts all on joint arm can be locked simultaneously or unclamp, and do not need doctor to remove one by one degree of tightness handwheel, lock.Two, doctor, in by microscope alignment patient focus, synchronously carries out pneumatic control locking, registration with pneumatic control switch on handle.In the time that doctor need readjust surgery location, or the continuous movement of patient can unclamp pneumatic control switch at any time, location fast again, quick locking.Three, the utility model utilizes the existing source of the gas of the department of stomatology, easy to operate, saves time, and raises the efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the rotating shaft cylinder locking device of the utility model oral cavity dentistry operation microscope joint arm.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the rotating shaft cylinder locking device of the utility model oral cavity dentistry operation microscope joint arm comprises joint arm axle sleeve 1, suction tude 2, solenoid valve 3, bearing 4, rotating shaft 5, clamp ring 6, and cap 7, thimble 8, pneumatic tube 9, the first cylinder 10, the second cylinder 11, the 3rd cylinder 12, four-cylinder 13, the 5th cylinder 14, the 6th cylinder 15, pneumatic control switch 19, joint arm axle sleeve 1 is enclosed within rotating shaft 5 by bearing 4, rotating shaft 5 is between bearing 4 and clamp ring 6, suction tude 2 is connected with solenoid valve 3, and cap 7 is positioned at the top of clamp ring 6, the first cylinder 10, the second cylinder 11, the 3rd cylinder 12, four-cylinder 13, the 5th cylinder 14, the 6th cylinder 15 is all connected with solenoid valve 3 by pneumatic tube 9, the first cylinder 10 is connected with thimble 8.Joint arm axle sleeve 1, bearing 4 are all positioned on a column 16.Solenoid valve 3 is positioned on a crossbeam 17, between the second cylinder 11, the 3rd cylinder 12, four-cylinder 13, the 5th cylinder 14, the 6th cylinder 15 5, connects by a link arm 18, and pneumatic control switch 19 is connected with solenoid valve 3.
Joint arm is by bearing housing in rotating shaft, and joint arm can carry out 360 ° of rotations along substantially horizontal like this, adds that a clamp ring is in the time having External Force Acting in clamp ring in rotating shaft, and clamp ring can be pinned rotating shaft, causes rotating shaft not rotate.Source of the gas is supplied with the pressurized air of 0.8MPa to solenoid valve by suction tude, control solenoid valve and give each cylinder air feed by pneumatic tube.When cylinder operation, the thimble of connection moves forward and acts on clamp ring, causes clamp ring to pin rotating shaft, and now all joints all can not freely be rotated.In the time stopping air feed, cylinder quits work, and thimble provides active force to clamp ring no longer forward, and all joints open can be freely movable.
Doctor is in the time adjusting to patient's affected area by the microscope on joint arm, needn't stand up to remove to screw each handwheel with hand, and the rotating shaft cylinder locking device of employing the utility model oral cavity dentistry operation microscope joint arm, by the pneumatic control switch on handle, carry pressurized air to go to lock each rotating shaft on joint arm to cylinder, and the operation that can utilize pneumatic control switch to unclamp at any time and lock, so just can accurately locate, easy-to-operat, raises the efficiency, and operation is carried out smoothly.
Above-described specific embodiment; technical problem, technological scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
