Abstract
The invention discloses an intra-cavity cutting anastomat. The intra-cavity cutting anastomat comprises a cannula, a cover plate and an assembly splint, wherein the cover plate and the assembly splint are connected to the two ends of the cannula respectively. The assembly splint is connected with a nail butting base in a rotating mode, and the front end of the assembly splint is connected with a nail bin. A cutting knife capable of moving in the direction of the nail bin during operation is arranged in the cannula, the front end of the cutting knife is sleeved with a knife locking piece used for locking the cutting knife, and anti-rotation cushion blocks capable of preventing the knife locking piece from being reversely rotated and disengaged are bonded between the knife locking piece and the cutting knife. According to the intra-cavity cutting anastomat, after the knife locking piece and the cutting knife are assembled in place, the two anti-rotation cushion blocks are bonded at the gaps between the two sides of the cutting knife and the knife locking piece, the knife locking piece and the cutting knife are firmly connected, and therefore the reverse rotation and disengaging phenomena happening in the using process of the knife locking piece can be effectively avoided.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of intracavity Endo-GIA.
Background technology
In intracavity Endo-GIA, the effect of lock knife is exactly dead knife, ensure it in the process cut and organized steadily forward, current structure is generally and lock knife is enclosed within after on cutter by certain angle, and rotation lock knife pins cutter to another location, and the cooperation of both requirements is very accurate, lock the tool setting of knife phase during final locked position can not rotate, this structure, when locking knife turned position and pinning cutter, lock knife is easy to produce and reverses obscission.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of and can firmly lock knife, prevents locking knife and produce the intracavity Endo-GIA reversing and come off.
The technical solution adopted for the present invention to solve the technical problems is: a kind of intracavity Endo-GIA, comprise sleeve pipe, be connected to the cover plate at sleeve pipe two ends and assembly clamping plate, assembly clamping plate are rotatably connected to nail supporting base, be positioned at assembly clamping plate front end and be connected with nail bin, to the cutter of nail bin direction movement when being provided with operation in sleeve pipe, cutter leading section is set with pins the lock knife of cutter, is bonded with to prevent locking knife and reverse the anti-rotation cushion block come off between described lock knife and cutter.
Further, described anti-rotation cushion block be two pieces points be located at cutter both sides with lock knife bond.
Described nail supporting base is provided with nail supporting base cover plate.
The invention has the beneficial effects as follows: the present invention is after lock knife and cutter are seated, to bond two anti-rotation cushion blocks at the lock knife gap location of cutter both sides, lock knife is firmly connected with cutter, thus effectively prevent the reverse obscission of locking knife and producing in use procedure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
In figure, knife 8. anti-rotation cushion block 9. nail supporting base cover plate locked by 1. sleeve pipe 2. cover plate 3. assembly clamping plate 4. nail supporting base 5. nail bin 6. cutter 7.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings only illustrate basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, a kind of intracavity Endo-GIA shown in Fig. 2, comprise sleeve pipe 1, be connected to cover plate 2 and the assembly clamping plate 3 at sleeve pipe 1 two ends, assembly clamping plate 3 are rotatably connected to nail supporting base 4, nail supporting base 4 is connected with nail supporting base cover plate 9, be positioned at assembly clamping plate 3 front end and be connected with nail bin 5, to the cutter 6 of nail bin 5 direction movement when being provided with operation in sleeve pipe 1, cutter 6 leading section is set with the lock knife 7 of pinning cutter 6, be bonded with between described lock knife and cutter and prevent locking knife and reverse the anti-rotation cushion block come off, described anti-rotation cushion block 8 has two pieces, two pieces of anti-rotation cushion blocks, 8 points of gap locations be located between cutter 6 both sides and lock knife 7 bond, come off to prevent lock knife 7 from reversing.
The present invention is after lock knife 7 is seated with cutter 6, to bond two anti-rotation cushion blocks 8 at lock knife 7 gap location of cutter 6 both sides, lock knife 7 is firmly connected with cutter 6, thus effectively prevent the reverse obscission of locking knife 7 and producing in use procedure.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
