Abstract
The invention relates to medical apparatus and instruments, particularly relating to adjustable wheel-pressure medical forceps, comprising a right forceps arm, a housing, a knob, a left forceps arm, two axial troughs, a rotating shaft, a regulating wheel and a pulley groove, wherein, the housing is a shell the side face of which is a right-angle trapezoid; the housing is sheathed on the right forceps arm and the left forceps arm; one side of the housing with a right-angle side and the right forceps are fixed into a whole; the middle part of one side of the housing with a sloping side is provided with a vertical pulley groove; the two sides of the inner side of the pulley groove are respectively provided with a strip-type axial trough; two ends of the rotating shaft of the regulating wheel are respectively positioned in the two axial troughs; and the regulating wheel is positioned in the pulley groove of the housing. The medical apparatus and instruments of the invention can clamp absorbent cotton all the time without long-time force applied by fingers, thus avoiding fatigue generation of fingers in the disinfectant process when the medical care personnel uses the forceps to clamp the absorbent cotton, and has the advantages of labor saving and convenient operation.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of adjustable wheel-pressure medical forceps.
Background technology
Existing tweezers do not have self-locking mechanism usually, use tweezers to clamp in the process that absorbent cotton carries out disinfection medical personnel, and finger is in the state to the two arm application of forces of tweezers all the time, if overlong time is easy to generate fatigue.
Summary of the invention
The present invention provides a kind of adjustable wheel-pressure medical forceps with auto-lock function for solving the deficiencies in the prior art.
The scheme that solves the technology of the present invention problem is: adjustable wheel-pressure medical forceps is made of right tweezer arm, sheath body, knob, left tweezer arm, axial trough, rotating shaft, regulating wheel and race.The upper end of right tweezer arm and left tweezer arm connects as one, and sheath body is that the side is the trapezoid housing in a right angle, and sheath body is enclosed within on right tweezer arm and the left tweezer arm, and the one side that sheath body has a right-angle side is pasted mutually with the outside of right tweezer arm and by knob right tweezer arm and sheath body is fixed as one.There is a race vertical, bar shaped at the middle part that sheath body has the one side of hypotenuse, and respectively there is the axial trough of a bar shaped on the both sides of the inboard of race.Regulating wheel is the oblate body that has burr on the periphery, and the place, axle center of regulating wheel is the rotating shaft that runs through regulating wheel and be in active relationship with regulating wheel.The two ends of rotating shaft are in respectively in the described axial troughs.Frictional force between rotating shaft and the axial trough can be fixing with the position relation of rotating shaft and axial trough when no external force applies.Regulating wheel is in the race of sheath body.The radius of regulating wheel is greater than the length of going to the bottom of sheath body side right-angled trapezium and the wall thickness sum of left tweezer arm.
During use, earlier right tweezer arm and left tweezer arm are clamped absorbent cotton, regulating wheel are being pushed away downwards with middle finger with thumb and forefinger, rotating shaft promptly in axial trough to lower slider, under the constraint of sheath body and under the extruding of regulating wheel, right tweezer arm and left tweezer arm close up.After unclamping finger, the frictional force between rotating shaft and the axial trough makes right tweezer arm and left tweezer arm be in the state that clamps absorbent cotton all the time.In the time of right tweezer arm and left tweezer arm need being opened, only need regulating wheel upwards pushed away getting final product.
Adopt such scheme, can reach following effect:
Because the present invention need not to point the long-time application of force and just can clamp absorbent cotton always, avoided medical personnel to use tweezers to clamp that finger produces fatigue in the process that absorbent cotton carries out disinfection.Has laborsaving, easy to operate advantage.

Fig. 2 is the left view of Fig. 1.
Among the figure: 1. right tweezer arm 2. sheath bodies 3. knobs 4. left tweezer arm 5. axial troughs 6. rotating shafts 7. regulating wheels 8. races
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Adjustable wheel-pressure medical forceps is made of right tweezer arm 1, sheath body 2, knob 3, left tweezer arm 4, axial trough 5, rotating shaft 6, regulating wheel 7 and race 8.
The upper end of right tweezer arm 1 and left tweezer arm 4 connects as one, sheath body 2 is that the side is the trapezoid housing in a right angle, sheath body 2 is enclosed within on right tweezer arm 1 and the left tweezer arm 4, and the one side that sheath body 2 has a right-angle side is pasted mutually with the outside of right tweezer arm 1 and by knob 3 right tweezer arm 1 and sheath body 2 is fixed as one.There is a race 8 vertical, bar shaped at the middle part that sheath body 2 has the one side of hypotenuse, and respectively there is the axial trough 5 of a bar shaped on the both sides of the inboard of race 8.Regulating wheel 7 is the oblate bodies that have burr on the periphery, and the place, axle center of regulating wheel 7 is the rotating shafts 6 that run through regulating wheel 7 and be in active relationship with regulating wheel 7.The two ends of rotating shaft 6 are in respectively in the described axial troughs 5.Frictional force between rotating shaft 6 and the axial trough 5 can be fixing with the position relation of rotating shaft 6 and axial trough 5 when no external force applies.Regulating wheel 7 is in the race 8 of sheath body 2.The radius of regulating wheel 7 is greater than the length of going to the bottom of sheath body 2 side right-angled trapezium and the wall thickness sum of left tweezer arm 4.
During use, earlier right tweezer arm 1 and left tweezer arm 4 are clamped absorbent cotton, regulating wheel 7 are being pushed away downwards with middle finger with thumb and forefinger, rotating shaft 6 promptly axial trough 5 in to lower slider, under the constraint of sheath body 2 with the extruding of regulating wheel 7 under, right tweezer arm 1 and left tweezer arm 4 close up.After unclamping finger, the frictional force between rotating shaft 6 and the axial trough 5 makes right tweezer arm 1 and left tweezer arm 4 be in the state that clamps absorbent cotton all the time.In the time of right tweezer arm 1 and left tweezer arm 4 need being opened, only need regulating wheel 7 upwards pushed away getting final product.
