Abstract
The invention discloses an intracavity incision anastomat. The intracavity incision anastomat comprises a fixed handle, a closed handle and a jaw opening and closing transmission mechanism which is connected with the closed handle. The closed handle is used for opening and closing a jaw, the closed handle is further connected with a closed handle linkage part, and a locking area is arranged on the closed handle linkage part. The locking area can be locked with an unlocking switch which is fixed on the fixed handle. The fixed handle is provided with a jaw closing safety device, and the unlocking switch can be limited by opening the jaw closing safety device. The locking area can not be locked with the unlocking switch when the jaw is closed, the jaw closing safety device is closed, and the locking area is locked with the unlocking switch when the jaw is closed. In the instrument original state, the jaw closing safety device is placed in the opened mode, closing and opening of the jaw can be operated freely, unlocking operation is needless, and using is convenient.
Description
Technical field
The invention belongs to medical instruments field, specifically be a kind ofly close the intracavity Endo-GIA of safety with jaw.
Background technology
Intracavity Endo-GIA is applied to abdominal cavity formula and interiorly peeps in operation, in use often needs freely clamp with the jaw of anastomat head or stir tissue.Needing to hold close handles when entering perforator jaw is closed, opening jaw after entering and operating, but the intracavity Endo-GIA used at present, jaw is lockable when closed, when again opening jaw, need unlocked step to realize, use and bother very much.
Summary of the invention
The technical problem to be solved in the present invention opens inconvenience after the jaw of intracavity Endo-GIA closes.
In order to solve the problems of the technologies described above, the scheme that the present invention takes is: intracavity Endo-GIA, comprise fixed handle, close handles and the jaw folding drive mechanism be connected with close handles, close handles is in order to folding jaw, close handles is also connected with close handles linkage part, close handles linkage part is provided with lock room, lock room can lock with the unlock switch be fixed on fixed handle, fixed handle is provided with jaw and closes safety, opening jaw closedown safety carries out spacing to unlock switch, during closed jaw, lock room can not lock with unlock switch, close jaw and close safety, during closed jaw, lock room and unlock switch lock.
Further, described jaw is closed safety and is comprised lock dog, pull bar, slide block moving part and slide block, lock dog one end is connected with fixed handle by bearing pin, the other end is keyed end, and lock dog body is connected with pull bar, and pull bar is connected with slide block by slide block linkage part, slide block is positioned at initial bit, lock dog carries out spacing to unlock switch, and slide block is positioned at end position, and lock dog is not spacing to unlock switch.
Further, fixed handle is provided with slide block linkage part spring.
Further, described jaw folding drive mechanism comprises drive link, contiguous block, sleeve and closed throw-out collar, and jaw folding drive mechanism and close handles interlock promote jaw and close or open.
The invention has the beneficial effects as follows, intracavity Endo-GIA of the present invention is provided with jaw and closes safety, close safety at apparatus original state jaw and be in open mode, hold close handles jaw to close, and close handles linkage part does not lock with unlock switch, unclamp close handles jaw to open, this process is without the need to unlocking operation, easy to use.When carrying out organizing cutting and stitching, close jaw and close safety, hold close handles when closing jaw, linkage part and unlock switch locks, and jaw locks, and organize clamped.

In figure, 1 nail bin seat, 2 nail supporting bases, 3 closed throw-out collars, 4 sleeves, 5 contiguous blocks, 6 drive links, 7 close handles moving parts, 8 unlock switch, 9 lock up gap, 10 boss, 11 unlock buttons, 12 lock dogs, 13 pull bars, 14 slide block moving parts, 15 slide block moving part springs, 16 slide blocks, 17 fixed handles, 18 close handles, 71 lock rooms.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further elaborated, and be below only one preferably embodiment, the present invention is not limited thereto.
As depicted in figs. 1 and 2, nail bin seat 1 and nail supporting base 2 define the jaw of apparatus, and close handles 18, drive link 6, contiguous block 5, sleeve 4, closed throw-out collar 3 belong to interlink function.Hold close handles 18, under the interlink function of drive link 6, contiguous block 5, sleeve 4, promote closed throw-out collar 3 travel forward, closed by the jaw opened, grasping tissue stirs.
Close handles moving part 7 is connected with close handles 18, be provided with lock room 71, described lock room 71 can lock with the unlock switch 8 be fixed on fixed handle 17, fixed handle 17 is provided with jaw and closes safety, opening jaw closedown safety carries out spacing to unlock switch 8, during closed jaw, lock room 71 can not lock with unlock switch 8, and close jaw and close safety, during closed jaw, lock room 71 and unlock switch 8 lock.
As a kind of preferred implementation, jaw is closed safety and is comprised lock dog 12, pull bar 13, slide block moving part 14 and slide block 16, lock dog 12 one end is connected with fixed handle 17 by bearing pin, the other end is keyed end, lock dog body is connected with pull bar 13, and pull bar 13 is connected with slide block 16 by slide block moving part 14, and slide block 16 is positioned at initial bit (as depicted in figs. 1 and 2), namely open jaw and close safety, lock dog 12 pairs of unlock switch 8 are carried out spacing.Slide block 16 is positioned at end position (as shown in Figure 3 and Figure 4), and namely close jaw and close safety, lock dog 12 pairs of unlock switch 8 are not spacing, and after close handles closed 18, lock room 71 locks with unlock switch 8, and jaw locks.
Apparatus enter perforator or other need close jaw and without the need to locking jaw time, slide block 16 is positioned at initial bit, jaw is closed safety and is opened, the keyed end of lock dog 12 enters the lock up gap 9 that unlock switch 8 is formed with boss 10, lock dog 12 can carry out spacing to unlock switch 8, hold close handles 18 when closing jaw, lock room 71 cannot lock with unlock switch 8 screens, as shown in Figure 2.
When needs open jaw, only need to loosen close handles 18 and just can stir by grasping tissue, as shown in Figure 1.
When needing locking jaw to carry out the cutting and stitching organized, the first step is closed jaw and is closed safety, stirs slide block 16 downwards, and lock dog 12 goes out of lock gap 9, and lock dog 12 no longer carries out spacing to unlock switch 8, as shown in Figure 3.Second step jaw locks, and after holding close handles 18, lock room 71 and the unlock switch screens of close handles moving part 7, as shown in A in Fig. 4, jaw is locked, and tissue is clamped.
Tissue cutting is complete, and jaw needs to open, and presses unlock button 11, and lock dog 12 moves upward reset under the effect of slide block moving part spring 15, and slide block 16 resets; The lock room 71 of unlock switch 8 and close handles moving part misplaces, and as shown in B in Fig. 5, close handles moving part 7 moves downward, and close handles 18 automatically resets thereupon.
