Abstract
The utility model relates to a miniature pneumatic bone saw which belongs to the technical field of medical appliances, and particularly relates to the miniature pneumatic bone saw used for bone surgery. The utility model comprises a saw blade 1, a casing 2, a switch press plate 3, a gas pipe joint 4, a valve body 17 and a pneumatic motor 18, and has the technical proposal that the miniature pneumatic bone saw is also provided with a locking nut 5, a saw blade clamping block 6, a reciprocating shaft 7, a connecting rod 8, a clamping head 9, a coupling device 10 and an eccentric head 20 of the coupling device. The utility model has the advantages of easy assembly and clamping of the saw blade, small size, light weight, smooth motion, safety function, optionally transport of the gas pipe joint, simple and reliable operation, etc., and is widely be used widely popularized and applied in medical units.
Description
This utility model belongs to technical field of medical instruments, particularly relates to a kind of minitype pneumatic bone saw that is used for bone surgery.
At present, domestic and foreign hospitals employed minitype pneumatic bone saw power section and motion parts are separate type, and gas-tpe fitting and bone saw can not rotate for being threaded, and saw blade is installed to be needed tighten with screwdriver, and switch does not have insurance function, complex operation.
The purpose of this utility model is a kind of monoblock type of design, and the saw blade that is installed is easy, has the minitype pneumatic bone saw of switch insurance.
The technical solution of the utility model accompanying drawings is as follows: the minitype pneumatic bone saw, comprise saw blade 1, housing 2, switch press plate 3, gas-tpe fitting 4, valve body 17, air motor 18, it is characterized in that: also have locking nut 5, saw blade fixture block 6, reciprocating shaft 7, connecting rod 8, dop 9, coupling 10, eccentric 20 of coupling, gas-tpe fitting 4 can rotate arbitrarily in valve body 17 and housing 2, and switch 11 can move on switch press plate 3, and switch press plate 3 has a hole 22 with valve rod 13 relative positions.Saw blade fixture block 6 overlaps upper locking nut 5 after inserting reciprocating shaft 7 front ends, connecting rod 8 one ends link to each other with reciprocating shaft 7 rear portions, the other end is connected with dop 9, the off-centre of coupling 10 20 cooperates with dop 9, coupling 10 another termination air motors 18, bearing 19 is equipped with at coupling 10 middle parts, and valve body 17 is equipped with several balls 16 with gas-tpe fitting 4 junction surfaces, housing 2 is fixing with valve body 17 by location-plate 12, and setscrew nut 21 is equipped with in housing 2 front portions.Operation principle of the present utility model: adopt compressed air to drive air motor 18 high speed rotating, by coupling 10 and eccentric 20 high speed swinging that high speed rotary motion is become dop 9 of coupling, and the saw blade 1 that drivening rod 8 moves back and forth, so be installed at a high speed on the reciprocating shaft 7 is just done reciprocating motion at a high speed.Operating process of the present utility model: at first saw blade 1 is inserted in the saw blade fixture block 6, rotation lock nut 5 clamps saw blade 1, and source of the gas is tapped into trachea 15, the exhaustor QI KOU 14 of running in, and moving switch 11 backward, press switch press plate 3 down, are duty; Trip switch pressing plate 3 is off working state; Move forward switch 11 and leave valve rod 13, press switch press plate 3 down, be safety position this moment, prevents misoperation.
Advantage of the present utility model: saw blade is installed easily; Volume is little in light weight, and moving equilibrium has insurance function, and gas-tpe fitting can rotate arbitrarily, and operation is simple and reliable.
Description of drawings: Fig. 1 is an axonometric chart of the present utility model, has represented saw blade 1, housing 2, switch press plate 3 among the figure, gas-tpe fitting 4; Fig. 2 is a main pseudosection of the present utility model, locking nut 5, saw blade fixture block 6, reciprocating shaft 7, connecting rod 8, dop 9, coupling 10, eccentric 20 of coupling, bearing 19, air motor 18, switch 11, valve rod 13, air inlet pipe 15 have been represented among the figure, air vent 14, valve body 17, ball 16, location-plate 12, Fig. 3 is the A place vertical view of Fig. 2, has represented hole 22 among the figure.
Embodiment: reach accompanying drawing to specifications and design the minitype pneumatic bone saw that meets national standard and always scheme installation diagram, part drawing.Selecting plastics, sealing member for use except that switch selects for use the rubber, all the other all select stainless steel material for use, the employing process for machining is produced, housing 2 external diameters are got 15mm, and air motor 18 is selected homemade high speed pneumatic vane motor for use, with the strict check of each part after producing, assemble according to installation diagram then, connect source of the gas, check whether duty adheres to specification, packing is promptly produced product of the present utility model at last.
