Description
Technical field
This utility model relates to a kind of shearing-type plaster saw, belongs to armarium technical field.
Background technology
In Orthopaedics Clinic, there are a lot of extremity fracture patients to adopt the treatment of Gypsum Fibrosum fixing means, wherein plaster cast is the conventional Therapeutic Method of doctor.In recent years, the appearance of macromolecule plaster bandage, has brought better treatment to select to fracture patient.Macromolecule plaster bandage claims again " AGMA ", and the macromolecular fibre being soaked into through polyurethane, polyester by multilamellar forms.Having the features such as sclerosis is fast, intensity is high, not water funk, is the upgrading products of conventional gypsum binder.But the development of plaster removing device tool relatively lags behind, it is rarely found having that electric plaster saw that safety precautions and quickness and high efficiency remove is applied in Orthopedic Clinical.
At present, more conventional orthopaedics plaster removing device tool is mainly manual gypsum cutter and electric plaster bandage saw.Manual gypsum cutter is by one end of the shears with protective measure is stretched between Gypsum Fibrosum edge and patient skin, and the other end is placed in gypsum surface, by shears interlock, to cut off Gypsum Fibrosum.Though gypsum cutter can not damage patient skin, it uses comparatively effort, and dismounting speed is slower, also may be because compressing patient swelling skin causes pain.Electric plaster bandage saw uses comparatively general in compared with large hospital; its high-speed rotation by circular saw blade is cut Gypsum Fibrosum; though save more manpower; but safety is poor, between Gypsum Fibrosum and skin, lack protective measure, in the uppity situation of depth of cut; very easily cause skin injury; and due to gypsum density inequality, when cutting, can cause too much vibration and noise, operator and patient are made troubles.
Summary of the invention
This utility model provides a kind of shearing-type plaster saw, the potential safety hazard existing for solving existing plaster removing device tool, and operation inconvenience, vibrates the problems such as large.
The technical solution of the utility model is: a kind of shearing-type plaster saw, comprises motor 1, safety guard 3, saw blade 4, handle 5, button 6, power line 7, connecting rod 8, torsion spring fulcrum 9, lever 10; Wherein the central axis of the output shaft of motor 1 and saw blade 4 aligns linked, the long end of lever 10 is fixedly connected with motor 1, the short end of lever 10 is connected with button 6, be positioned at torsion spring fulcrum on lever 10 9 inner hinged with handle 5, safety guard 3 is under saw blade 4, in one plane, the power line 7 that is positioned at handle 5 one end is connected with motor 1 for connecting rod 8 and saw blade 4.
Also comprise containment vessel 2, wherein containment vessel 2 blocks saw blade 4, and shielded area is extremely from upwards 1/5th saw blade 4 radial height of saw blade 4 lower limbs from saw blade 4 top edges.
The width of described safety guard 3 is greater than the thickness of saw blade 4.
The front end of described safety guard 3 does Passivation Treatment.
The width of described connecting rod 8 is less than or equal to the thickness of saw blade 4.
In in described torsion spring fulcrum 9, establish torsion spring.
Operation principle of the present utility model is: the inner lever construction that adopts of plaster saw, one end connection button 6(of lever 10 is that the short end of lever 10 is connected with button 6, what short end represented is the shorter one end of distance between element and torsion spring fulcrum 9), other end connection motor 1(is that the long end of lever 10 is fixedly connected with motor 1, what long end represented is one end that the distance between element and torsion spring fulcrum 9 is grown), this button 6 is the volume under pressure that on and off switch also can be controlled electric saw, and due to lever principle, make to apply a less power at turret terminal, electric saw end just can have a larger downward shearing force, be more suitable for high strength gypsum binder, the frictional force of electric saw is combined with shearing force, make cutting more laborsaving, and the Gypsum Fibrosum of different-thickness is had to better adaptive capacity, in the time disassembling Gypsum Fibrosum, become shearing propelling from common linear advancement motion, saw blade 4 can from the superficial to the deep cut Gypsum Fibrosum, saw blade 4 and the contact area of Gypsum Fibrosum are changed from small to big, active force also changes from small to big, and makes cutting action effective gently, reduces the vibration of plaster saw and Gypsum Fibrosum in the time that cutting has some setbacks, reduce operator's operation easier, also reduced due to the excessive sense of discomfort of bringing to patient of vibration, the torsion spring fulcrum 9 being positioned on lever 10 is established torsion spring, be used for the gravity of balance electric saw end, make to press down rear saw blade 4 at every turn and can arrive original height by automatic rebounding, conveniently carry out continuous shearing cutting, like this cutting action of gypsum cutter and plaster saw is effectively combined, greatly increased cutting efficiency, safety guard 3 is set under saw blade 4, and safety guard 3 stretches into the gap between Gypsum Fibrosum and patient skin, can avoid pressing down shearing mistiming and hinder skin, eliminates patient's feared state of mind.
When use, the hand-held shearing-type plaster saw of user carries out Gypsum Fibrosum while disassembling, safety guard 3 is stretched into Gypsum Fibrosum and patient skin gap, (safety guard 3 front end passivation can not scrape skin while making it to contact with patient skin) now Gypsum Fibrosum body edge at saw blade 4 centre with safety guard 3.Afterwards, pressing button 6, when pressing button 6, not only opened motor 1 and driven saw blade 4 to rotate but also saw blade 4 is pressed down, Gypsum Fibrosum had been cut out after place's otch, just can at the uniform velocity push ahead, and in the time that cutting has some setbacks, repeatedly carry out the action of pressing button 6, the pressing force of finger presses down by the frictional force of saw blade 4 and saw blade 4 shearing force of bringing by lever 10 and act on Gypsum Fibrosum, the vibration that reduces to bring simultaneously in the time that cutting has some setbacks, reduce operator's operation easier, increase patient's comfort level.
Due to the existence of the torsion spring of establishing in torsion spring fulcrum 9, after each pressing button 6, all can make saw blade 4 automatically rebound, conveniently carry out the shear action that presses down next time.Now, connecting rod 8 can enter in the Gypsum Fibrosum breach that saw blade 4 cuts, and can keep so continuous cutting operation, thereby make plaster saw successfully unload Gypsum Fibrosum from patient skin.The comfortable size of gripping of the size conforms staff of handle 5, and can observe easily from the side the cutting position of saw blade 4 and cut direction and whether in poised state, thus bring great convenience to medical worker's operation.Finally, due to the existence of containment vessel 2, in use, operator can not be subject to the injury that saw blade 4 brings equally.For alleviating the weight of plaster saw, and due to the existence of lever 10, preferably, can select moment of torsion suitably little, the less micromachine of weight is as driver.
The beneficial effects of the utility model are:
1, the lever construction of inner employing is simple, and reliable in action can less pressing force provides the downforce of larger saw bit end, reaches labour-saving object.
2, torsion spring can make saw blade automatically rebound after pressing down, and can carry out easily the cutting that presses down next time, makes shear action more smooth and easy, improves cutting efficiency.
3, press down while shearing, saw blade and Gypsum Fibrosum contact area are changed from small to big, and contact force also has little change large, and transition nature has reduced vibration when cutting has some setbacks effectively, handled easily person, and increase patient's comfort level.
4, the existence of safety guard and containment vessel, makes operator and patient all avoid the injury of saw blade, and has reduced patient's the feared state of mind.
