Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to the replaceable quick handle of a kind of screw tap.
Background technology
The screw tap of the different model that existing hands surgery is used mostly is the holder that is equipped with oneself separately, though such design is simple in structure, but because screw tap is fragile, be an indivisible integral body with holder again simultaneously, therefore intact holder also can become waste product because of the damage of screw tap, this makes the cost of operating theater instruments too high, causes waste.Simultaneously, because the perioperatively medical apparatus and instruments needs disinfection, holder 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 and its holder 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.
The utility model content
This utility model is for solving the deficiencies in the prior art, provide a kind of can the realization to be connected fast easily and quick-detach, replacing soon between screw tap replacement head and the holder, can make between the two again can stablize, firmly, the replaceable quick handle of the bonded screw tap in non-loosening ground.
The scheme that solves this utility model technical problem is: the replaceable quick handle of screw tap is made of lever, switch bar, annular protrusion, shaft seat, chute, slide-bar seat, slide-bar, gim peg, seal mouth ring, spring, action bars, replacement head, blind hole and lock hole.Wherein, action bars has the cylinder of an axial blind hole for lower end central authorities, and the upper end and the lever of action bars are combined as a whole.Replacement head is by bar portion and be connected to holistic screw tap head with bar portion two ends respectively and pedestal constitutes.Pedestal and bar portion are co-axial cylinder, and bar portion diameter is less than susceptor diameter.One circular hole is arranged on the sidewall of pedestal.Pedestal is in the blind hole and with blind hole and becomes assembling to concern movingly.One lock hole that communicates with blind hole is arranged on the sidewall of action bars.Gim peg is the cylinder bodily form, an end of gim peg have with gim peg be holistic slide-bar seat, also have on the sidewall of gim peg with gim peg be holistic annular protrusion.Gim peg and annular protrusion are in the lock hole and annular protrusion and lock hole are in active relationship, and gim peg does not insert in the circular hole of replacement head pedestal with an end of slide-bar seat.Seal mouth ring is that cross section is orthogonal torus, and seal mouth ring embeds in the lock hole and the outer wall of seal mouth ring combines with screw thread with lock hole, and seal mouth ring is placed in gim peg and has on the end of slide-bar seat and with gim peg and be in active relationship.Spring be placed on the gim peg and be compressed in annular protrusion and seal mouth ring between.On the sidewall of action bars, be connected to holistic shaft seat with action bars in addition, have on the shaft seat with shaft seat be holistic rotating shaft.The switch bar is the vertical bar that has linear bending, in the rotating shaft that the bending place of switch bar is placed in and with rotating shaft become rotation to concern movingly.On the straight section of switch bar a chute is arranged, with the slide-bar seat be that holistic slide-bar is in the described chute and can slides along chute.
When needing to change screw tap, only need the switch bar is pressed, the chute of perk is pulled outwardly the slide-bar seat, and the slide-bar seat drives gim peg and outwards moves, and extract out from the circular hole of replacement head pedestal the end of gim peg, and replacement head can be extracted out from blind hole easily.When new replacement head is installed, only need earlier the switch bar to be pressed, the pedestal with replacement head inserts back trip switch bar in the blind hole again, and the rotation replacement head, when the circular hole of replacement head pedestal was corresponding with gim peg, gim peg can insert in the circular hole automatically under the effect of spring replacement head is fixed.
Adopt such scheme, can reach following effect:
1. these have multiple model and flimsy apparatus fabricate becomes interchangeable member and separates setting with action bars because this utility model is with screw tap, greatly reduce the cost of operating theater instruments like this, avoided waste, because replacement head can be concentrated separately and carry out disinfection, disinfection space and cost of transportation have been saved simultaneously.
2. because the mode that this utility model has adopted the circular hole of gim peg and replacement head pedestal sidewall to plug together fixes replacement head, compared with prior art, the situation of in use having stopped fully to skid between screw tap and the holder takes place, and has good steadiness.
3. because this utility model only need just can realize that the fixing and releasing of replacement head is fixing by unclamping with the depress switch bar, make the installation or removal process very convenient quick.
4. because replacement head of the present utility model is simple in structure, and its shape only is the simple geometric body, easily process, cost is low.
