Abstract
The utility model discloses an error-proof percussion safety mechanism of a straight-line incision anastomat. The error-proof percussion safety mechanism of the straight-line incision anastomat comprises an assembly seat frame and a percussion mechanism. The percussion mechanism is provided with a percussion drive device. The percussion drive device comprises a screw rod, a transmission nut and a rotating handle. The rotating handle is connected with one end of the screw rod in an inserting mode. The transmission nut and the screw rod form a screw rod nut pair. The error-proof percussion safety mechanism of the straight-line incision anastomat further comprises a safety accessory. The safety accessory is provided with a first clamping groove used for clamping the rotating handle. The safety accessory is further provided with a second clamping groove used for clamping the assembly seat frame. The error-proof percussion safety mechanism of the straight-line incision anastomat can prevent a misoperation phenomenon caused by rotation of the rotating handle when the straight-line incision anastomat does not work.
Description
Technical field
This utility model relates to a kind of anti-error percussion insurance institution of linear cutting anastomat, belongs to technical field of medical instruments.
Background technology
At present, the employed firing lock of prior art is the push button driving normally, its operation principle is: promote the percussion button, inner mobile by tiltedly carving at nail bin, tiltedly carve the drive push jack, anastomosis staple is released the nail bin surface until molding, the percussion structure is that firing action is finished in direct promotion by people's hands when performing an operation, this kind mode is high to the requirement (skill and dynamics on hand) of user, in case skill and dynamics are grasped not goodly is easy to cause the apparatus percussion motionless and can only pull the trigger half, finally causes operative failure, risk is high, so, improvement has designed the structure that a kind of feed screw nut's formula percussion drives, but in practice process, when linear cutting anastomat is not worked, turning handle rotates easily, causes maloperation.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of anti-error percussion insurance institution of linear cutting anastomat is provided, and it can prevent that when linear cutting anastomat is not worked turning handle from rotating and the maloperation phenomenon that takes place.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of anti-error percussion insurance institution of linear cutting anastomat, comprise assembly mounting and firing lock, firing lock has the percussion driving device, the percussion driving device comprises screw mandrel, transmission nut and turning handle, one end of turning handle and screw mandrel is pegged graft, transmission nut and screw mandrel are formed feed screw nut pair, also comprise the insurance adnexa, described insurance adnexa has first draw-in groove that blocks turning handle, and described insurance adnexa also has second draw-in groove that blocks the assembly mounting.
Further, described second draw-in groove has two, and described first draw-in groove is arranged on the middle part of insurance adnexa, and described two second draw-in grooves lay respectively at the both sides of first draw-in groove.
After having adopted technique scheme, when not using linear cutting anastomat, insurance adnexa of the present utility model can be turning handle and assembly mounting relative fixed, when using linear cutting anastomat, pull up the insurance adnexa, turning handle is namely rotatable, very convenient, has prevented that turning handle rotates and the maloperation phenomenon of generation when linear cutting anastomat is not worked.
Description of drawings
Fig. 1 is the anti-error installation axonometric chart of pulling the trigger insurance institution of linear cutting anastomat of the present utility model;
Fig. 2 is the axonometric chart of insurance adnexa of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below,
Shown in Fig. 1 ~ 2, a kind of anti-error percussion insurance institution of linear cutting anastomat, comprise assembly mounting 12 and firing lock, firing lock has the percussion driving device, the percussion driving device comprises screw mandrel 2, transmission nut 3 and turning handle 1, turning handle 1 is pegged graft with an end of screw mandrel 2, transmission nut 3 is formed feed screw nut pair with screw mandrel 2, also comprise insurance adnexa 8, insurance adnexa 8 has the first draw-in groove 8-1 that blocks turning handle 1, and insurance adnexa 8 also has the second draw-in groove 8-2 that blocks assembly mounting 12.
As shown in Figure 2, the second draw-in groove 8-2 has two, and the first draw-in groove 8-1 is arranged on the middle part of insurance adnexa 8, and two second draw-in groove 8-2 lay respectively at the both sides of the first draw-in groove 8-1.
Operation principle of the present utility model is as follows:
When not using linear cutting anastomat, insurance adnexa 8 of the present utility model can be turning handle 1 and assembly mounting 12 relative fixed, when using linear cutting anastomat, pull up insurance adnexa 8, turning handle 1 is namely rotatable, very convenient, prevented that turning handle 1 rotates and the maloperation phenomenon of generation when linear cutting anastomat is not worked.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
