Abstract
The invention relates to a medical appliance, in particular to a backwards-turnable type hand surgery quick-assembling handle. The backwards-turnable type hand surgery quick-assembling handle consists of a base, a positioning groove, an anti-rotation groove, a sleeve, a positioning block, a snap ring, a tail disk, a spring, a handle, a raised strip and a replaceable head, wherein the base is cylindrical; an n-shaped positioning groove is formed on a side wall of the base; the positioning block is a cubic bulge positioned on a side wall of the left end of the handle; the positioning block and the handle are formed into a whole; and the positioning block is positioned in the positioning groove and is movably matched with the positioning groove. Compared with the prior art, the backwards-turnable type hand surgery quick-assembling handle fully avoids stripping between a screw driver or a screw tap and a handle by adopting the n-shaped positioning groove to lock the base of the replaceable head and the handle when used, is stable, and can be conveniently and quickly assembled and disassembled at the same time.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of formula hands surgery quick-mounting handle of turning round back.
Background technology
The screw tap that existing hands surgery is used, the screwdriver of immersing oneself in device and being screwed into screw etc. mostly are the handles that is equipped with oneself separately, though such design is simple in structure, but because screw tap, screwdriver are fragile, be an indivisible integral body with handle again simultaneously, therefore intact handle also can become waste product because of the damage of screw tap, screwdriver, this makes the cost of operating theater instruments too high, causes waste.Simultaneously, because the perioperatively medical apparatus and instruments needs disinfection, handle can occupy bigger space after entering sterilizing equipment decontaminating apparatus, has increased the disinfectant cost on the one hand, has also reduced disinfectant efficient simultaneously.
Avoid the problems referred to above, just must make screw tap, screwdriver and its handle separable, but accomplish both can easily connect fast between the two and quick-detach, replacing soon, make again between the two can stablize, firmly, the combination of non-loosening ground, but to be those skilled in the art thirst for to solve the problem that always can thoroughly not solve for many years always for this.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provides a kind of can the realization to be connected fast easily and quick-detach, replacing soon between replacement head and the handle, can make between the two again can stablize, firmly, the bonded formula hands surgery quick-mounting handle of turning round back in non-loosening ground.
The scheme that solves the technology of the present invention problem is: turn round back formula hands surgery quick-mounting handle and be made of pedestal, locating slot, anti-rotation groove, sleeve, locating piece, snap ring, final quotaion, spring, handle, raised line and replacement head.Wherein, pedestal is the cylindrical shape that left end sealing right-hand member is opened wide, the left end and the replacement head of pedestal are as a whole, have on the sidewall of pedestal one longitudinally, cross section is orthogonal anti-rotation groove, the locating slot that also has η shape on the sidewall of pedestal, unequal vertically straight trough and a transverse groove constitute locating slot longitudinally along pedestal by two length.The left justify of two vertical straight troughs, transverse groove laterally connects the left end of described two vertical straight troughs.Locating slot connects the interior or exterior space of pedestal, and wherein the right-hand member of a long vertical straight trough is opened wide and be concordant with the right side of pedestal.Handle is cylindrical, the right-hand member of handle be with handle be holistic discoidal final quotaion, locating piece is the cube shaped projection that is positioned on the sidewall of left end of handle, locating piece and handle are as a whole.Sleeve is a cylindrical shape, on the inwall of telescopic middle part snap ring is arranged, snap ring be with telescopic inwall be holistic annular solid, handle is in the sleeve and passes snap ring and be in active relationship with snap ring.On the handle between snap ring and the final quotaion, be with spring.The inwall of sleeve left end also has one to be holistic, raised line longitudinally with sleeve.Pedestal is in the telescopic left end and with sleeve and becomes assembling to concern movingly, the left end of handle inserts in the pedestal and with pedestal and becomes assembling to concern movingly, raised line is in the anti-rotation groove and becomes assembling relation movingly with anti-rotation groove, and locating piece is in the locating slot and with locating slot and becomes assembling to concern movingly.
In the time of replacement head need being taken off, only need push final quotaion left, make locating piece slide into the left end of short vertical straight trough of locating slot, rotary handle again, make locating piece slide into the left end of a vertical straight trough of length of locating slot along the transverse groove of locating slot, can extract replacement head and pedestal out easily this moment from telescopic left end.
When needing new replacement head is installed, only the anti-rotation groove of pedestal need be alignd with telescopic raised line and pedestal is inserted in the sleeve, rotary handle makes the right output port of long vertical straight trough of the locating piece positioned in alignment groove of handle, and to the left end driving handle, when locating piece slides into the long vertical straight trough left end of locating slot, rotary handle makes locating piece slide into the left end of short vertical straight trough of locating slot along the transverse groove of locating slot, after unclamping hands, locating piece slides into the right-hand member of the short vertical straight trough of locating slot under the promotion of spring, and this moment, pedestal and replacement head were locked.
Adopt such scheme, can reach following remarkable technique effect:
1. owing to the present invention screwdriver, these flimsy apparatus fabricates of screw tap are become interchangeable member and separate setting with action bars, greatly reduce the cost of operating theater instruments like this, avoid waste, because replacement head can be concentrated separately and carry out disinfection, saved disinfection space and cost of transportation simultaneously.
2. the present invention's mode of having adopted the locating slot of η shape to combine with the locating piece of handle locks the pedestal and the relation of the position between the handle of replacement head, compared with prior art, the situation of in use having stopped fully to skid between screwdriver, screw tap and the handle takes place, has good steadiness, simultaneously, installation or removal process is also very convenient quick.
