Abstract
The utility model discloses a kind of anti-lock intracavity anastomat, the jaw folding drive mechanism comprising fixed handle, close handles and be connected with close handles, close handles is also connected with handle locking connector, handle locking connector can lock with unlock switch, it is characterized in that, unlock switch is provided with anti-lock-switch, when handle locking connector and unlock switch are in unlocked state, anti-lock-switch and unlock switch limitation locking; When handle locking connector and unlock switch are in the lock state, anti-lock-switch and unlock switch is spacing unblanks.Effectively can avoid locking the mistake of jaw in operation process, improve instrumentation safety.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of anti-lock intracavity anastomat.
Background technology
Current intracavity Endo-GIA is more general to be applied in the reconstruction operations of stomach, Colon and rectum etc.Sometimes in order to find the best clip position of tissue in operation, need to stir tissue, doctor can utilize intracavity Endo-GIA to clamp and stir tissue, but in the process used, as firmly jaw locked slightly greatly.Jaw must be unclamped could again stir tissue by being unlocked by pressing switch after jaw locking, troublesome poeration.Even due to above-mentioned maloperation, jaw is locked and is clamped the tissue that should not press from both sides, tissue is damaged, adds operation risk.
Summary of the invention
The problem that will solve of the present utility model there is jaw locking by mistake when organizing in anastomat clamping, upset, causes the problem of tissue injury, provide a kind of lock-out state of jaw controllable anti-lock intracavity anastomat.
The scheme that this utility model solves the problems of the technologies described above is:
Anti-lock intracavity anastomat, the jaw folding drive mechanism comprising fixed handle, close handles and be connected with close handles, close handles is also connected with handle locking connector, handle locking connector can lock with unlock switch, it is characterized in that, unlock switch is provided with anti-lock-switch, when handle locking connector and unlock switch are in unlocked state, anti-lock-switch and unlock switch limitation locking; When handle locking connector and unlock switch are in the lock state, anti-lock-switch and unlock switch is spacing unblanks.
Optimize structure as one, the gim peg of anti-lock-switch both sides is fixed on fixed handle, the clamping block at middle part coordinates with the dead bolt in unlock switch, and when clamping block and dead bolt screens, anti-lock Switch Controller unlock switch is spacing, and unlock switch cannot lock with handle locking connector; When clamping block and dead bolt depart from (namely unlocking), anti-lock Switch Controller unlock switch unlocks, and unlock switch can lock with handle locking connector.
The beneficial effects of the utility model are, add the anti-lock-switch coordinated with unlock switch, by locking or the unblock of anti-lock Switch Controller unlock switch, control coordinating between locking switch with handle locking connector, thus control the lock-out state of jaw, avoid locking the mistake of jaw in operation process.In addition, anti-lock-switch can also play instant lock function in operation process, when apparatus needs to take out from abdominal cavity, presses unlock switch to maximum position, jaw opens, anti-lock-switch return, anti-lock-switch and unlock switch lock, and close handles of can holding with a firm grip takes out apparatus, jaw opens when trip switch, directly change new nail bin to carry out using next time, repeatedly need not unlock by being unlocked by pressing switch, simplify and use step.

In figure, 1 nail bin seat, 2 nail supporting bases, 3 closed throw-out collars, 4 sleeves, 5 contiguous blocks, 6 ejector pin retaining plates, 7 unlock switch, 71 dead bolts, 8 anti-lock-switch, 81 gim pegs, 82 clamping blocks, 9 unlock buttons, 10 springs, 11 handle locking connectors, 12 fixed handles, 13 close handles, 14 return springs.
Detailed description of the invention
As shown in Figure 1, nail bin seat 1 and nail supporting base 2 define the jaw of apparatus, and close handles 13, ejector pin retaining plate 6, contiguous block 5, sleeve 4, closed throw-out collar 3 belong to interlink function.Hold close handles 13, under the interlink function of ejector pin retaining plate 6, contiguous block 5, sleeve 4, promote closed throw-out collar 3 travel forward, closed by the jaw opened, grasping tissue stirs.
Close handles 12 is also connected with handle locking connector 11, and handle locking connector 11 can lock with unlock switch 7.Anti-lock-switch 8 is provided with above unlock switch 7, the structure of the unlock switch of the present embodiment is see Fig. 4, anti-lock construction of switch is see Fig. 5, and anti-lock-switch 8 is fixed on fixed handle 12 by the gim peg 81 of both sides, and the clamping block 82 at middle part coordinates with the dead bolt 71 in unlock switch 7.When being unlocked by pressing button 9 spring 10 is out of shape, when unlock switch 7 is pressed into maximum position, dead bolt 71 in unlock switch 7 locks with clamping block 82, limit function between unlock switch 7 and handle locking connector 11 lost efficacy, apparatus is in unlocked state (Fig. 2), operation close handles 13 can realize the freely openable of jaw, and doctor can utilize apparatus to carry out clamping or stirring tissue.When needs apparatus jaw locking, when carrying out cutting and stitching function, press anti-lock-switch 8 to the left or to the right, the clamping block 82 of anti-lock-switch 8 unlocks with the dead bolt 71 of unlock switch 7, unlock switch 7 can be discharged, the limit function that unlock switch 7 and handle close between connector 11 comes into force, and apparatus is in the lock state (Fig. 3), operation close handles can realize jaw locking, completes the normal function of apparatus.Anti-lock-switch 8 in unlock switch 7 by can self-return during maximum position, self-return principle is: return spring 14 is enclosed within anti-lock switch shaft on both sides, when anti-lock-switch 8 non-locking unlock switch 7, as shown in Figure 6, return spring 14 is in Pre strained state, now press unlock switch 7 to maximum position, anti-lock-switch will be returned to position shown in Fig. 7 under spring force, thus locking unlock switch.This design can realize all exercisable characteristic of left and right both direction.
