Description

Intracavity Endo-GIA
Technical field
The invention belongs to medical instruments field, specifically be a kind of with jaw close safety intracavity Endo-GIA.
Background technology
Intracavity Endo-GIA is applied to abdominal cavity formula and interior peeps in operation, the most often needs freely clamp with the jaw of anastomat head or stir tissue.Need to hold close handles to be closed by jaw when entering perforator, open jaw after entrance and operate, but currently used intracavity Endo-GIA, jaw is lockable when Guan Bi, when being again turned on 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 be intracavity Endo-GIA jaw Guan Bi after open inconvenience.
In order to solve above-mentioned technical problem, the scheme that the present invention takes is: intracavity Endo-GIA, including fixed handle, close handles and the jaw folding drive mechanism being connected with close handles, close handles is in order to folding jaw, close handles is also connected with close handles linkage part, it is provided with lock room on close handles linkage part, lock room can be with the unblock switch locking being fixed on fixed handle, it is provided with jaw on fixed handle and closes safety, open jaw closedown safety and carry out spacing to solving lock-switch, during Guan Bi jaw, lock room can not lock with unlocking switch, close jaw and close safety, during Guan Bi jaw, lock room locks with unlocking switch.
Further, described jaw is closed safety and is included 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 solving lock-switch, and slide block is positioned at end position, and lock dog is the most spacing to solving lock-switch.
Further, fixed handle is provided with slide block linkage part spring.
Further, described jaw folding drive mechanism includes that drive link, contiguous block, sleeve and Guan Bi throw-out collar, jaw folding drive mechanism and close handles interlock promotion jaw Guan Bi 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 switchs locking with unlocking, unclamping close handles jaw to open, this process is without solving latching operation, easy to use.When carrying out tissue cutting and sewing up, closing jaw closedown safety, when holding close handles Guan Bi jaw, linkage part locks with unlocking switch, and jaw locks, and tissue is clamped.

In figure, 1 staple cartridge tray, 2 nail supporting bases, 3 Guan Bi throw-out collars, 4 sleeves, 5 contiguous blocks, 6 drive links, 7 close handles moving parts, 8 solve lock-switch, 9 lock up gap, 10 boss, 11 unlock button, 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 the most only one preferably embodiment, the invention is not limited in this.
As depicted in figs. 1 and 2, staple cartridge tray 1 and nail supporting base 2 define the jaw of apparatus, and close handles 18, drive link 6, contiguous block 5, sleeve 4, Guan Bi throw-out collar 3 belong to interlink function.Hold close handles 18, drive link 6, contiguous block 5, sleeve 4 interlink function under promote Guan Bi throw-out collar 3 travel forward, will open jaw Guan Bi, clamping tissue stir.
Close handles moving part 7 is connected with close handles 18, it is provided with lock room 71, described lock room 71 can lock with the solution lock-switch 8 being fixed on fixed handle 17, it is provided with jaw on fixed handle 17 and closes safety, open jaw closedown safety and carry out spacing to solving lock-switch 8, during Guan Bi jaw, lock room 71 can not lock with solving lock-switch 8, closes jaw and closes safety, and during Guan Bi jaw, lock room 71 locks with solving lock-switch 8.
As a kind of preferred implementation, jaw is closed safety and is included 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), i.e. opening jaw and close safety, lock dog 12 carries out spacing to solving lock-switch 8.Slide block 16 is positioned at end position (as shown in Figure 3 and Figure 4), i.e. closes jaw and closes safety, and lock dog 12 is the most spacing to solving lock-switch 8, and after close handles Guan Bi 18, lock room 71 locks with solving lock-switch 8, and jaw locks.
Apparatus enter perforator or other need to close jaw and during without locking jaw, slide block 16 is positioned at initial bit, jaw is closed safety and is opened, the keyed end of lock dog 12 enters and solves the lock up gap 9 that lock-switch 8 is formed with boss 10, lock dog 12 can carry out spacing to solving lock-switch 8, hold close handles 18 when closing jaw, lock room 71 cannot with solve lock-switch 8 screens locking, as shown in Figure 2.
When needs open jaw, it is only necessary to loosen close handles 18 and just can clamp tissue and stir, as shown in Figure 1.
When the cutting needing locking jaw to carry out organizing is sewed up, the first step is closed jaw and is closed safety, stirs downwards slide block 16, and lock dog 12 departs from lock up gap 9, and solution lock-switch 8 is no longer carried out spacing, as shown in Figure 3 by lock dog 12.Second step jaw locks, and after holding close handles 18, the lock room 71 of close handles moving part 7 switchs screens with unlocking, and 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 unblock 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 solving lock-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 therewith.
