Specific embodiment
Core of the invention is to provide a kind of stitching unstrument that can prevent secondary percussion.
It is below in conjunction with attached drawing and specifically real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 5, a kind of suture with percussion locking device is provided according to one embodiment of present invention
Device is arranged in release button 11 including stitching unstrument ontology 1, the nail pushing plate being mounted on stitching unstrument ontology 1 12 and release button 11
There is nail pushing plate locking plate 111, nail pushing plate protrusion 121 is provided on nail pushing plate 12, the distal end of nail pushing plate locking plate 111 can be with nail pushing plate
Protrusion 121 abuts.As shown in Figure 1, nail pushing plate locking plate 111 is not raised with nail pushing plate under the original state before stitching unstrument use
121 contacts, nail bin 15 are in original state；With further reference to Fig. 2, the closed state of stitching unstrument is shown, holds suture at this time
The lower jaw that the close handles 14 of device, nail bin 15 and stitching unstrument execute end is closed；With further reference to Fig. 3, stitching unstrument is shown
Cock holds the firing handle 13 of stitching unstrument at this time, which makes nail pushing plate 12 advance, and nail pushing plate 12 pushes away in turn
Staple in dynamic nail bin 15, and push cutter (not shown) to cut tissue, after percussion, nail pushing plate locking plate 111 it is remote
End 121 is abutted with nail pushing plate protrusion just, locks nail pushing plate 12, therefore stitching unstrument will not return to original state, therefore even if
Doctor holds firing handle 13 because of maloperation again, and firing handle 13 will not rise to push to nail pushing plate 12 and cutter again to be made
With to prevent the secondary percussion of stitching unstrument, that is, avoiding the secondary cut tissue of cutter, prevent malpractice.
Above-mentioned ejector pin locking plate 111 can be made by leaf spring or by other elastic materials, and release button 11 can be solid with nail pushing plate locking plate 111
Fixed connection.
Further, as shown in figure 5, nail pushing plate locking plate 111 can also be connected with release button 11 by 112 activity of pin
It connects, torsional spring 113 is provided on pin 112.Nail pushing plate locking plate 111 can be relative to 11 carry out activity of release button as a result, and turns round
Spring 113 makes the distal end of nail pushing plate locking plate 111 keep inclination downward, can guarantee that the distal end of nail pushing plate locking plate 111 can be in this way
Nail pushing plate protrusion 121 abuts, and such mode keeps the operation of nail pushing plate locking plate 111 more flexible and stablizes.
Further, referring to fig. 4, stitching unstrument according to the present invention can also include the instruction card 16 connecting with nail pushing plate 12
And the indicating window (not shown) being connect with instruction card 16.Under the original state of stitching unstrument, nail pushing plate locking plate 111 not with ejector pin
Plate protrusion 121 contacts, and the indicating window connecting at this time with instruction card 16 is shown as white.Further, in the closed form of stitching unstrument
Under state, the close handles 13 of stitching unstrument are held, then the lower jaw of nail bin 15 and stitching unstrument end effector is closed, and nail pushing plate 12 drives
Instruction card 16 moves, and keeps indicating window shown in green.Further, under the cock of stitching unstrument, hitting for stitching unstrument is held
Handle 13 is sent out, nail pushing plate 12 advances, and the staple in nail bin 15 is fired, and push cutter to cut tissue, at this point, nail pushing plate is locked
The distal end of piece 111 is abutted with nail pushing plate protrusion 121, keeps nail pushing plate 12 locked without retreating, so that stitching unstrument will not return just
Beginning state, the indicating window connecting at this time with instruction card 16 is shown in red, since instruction card 16 is connect with nail pushing plate 12, in ejector pin
In the case that plate 12 is locked, instruction card 16 also locks motionless, therefore before pressing release button 11, indicating window will be always maintained at
It is displayed in red, reminds operator's stitching unstrument that percussion is completed.
Further, nail pushing plate protrusion 121 can be positioned below fluted (not shown), after the completion of stitching unstrument percussion, push away
In the embeddable groove in the distal end of nail-plate locking plate 111, distal end and the nail pushing plate that can further avoid nail pushing plate locking plate 111 in this way are convex
It plays 121 and abuts retrolisthesis.The setting of groove can make nail pushing plate locking plate 111 more firm when abutting with nail pushing plate protrusion 121.More into
One step, as shown in figure 5, the distal end of nail pushing plate locking plate 111 is provided with locking plate protrusion 1111, locking plate protrusion 1111 makes nail pushing plate
The contact area of locking plate 111 and nail pushing plate protrusion 121 reduces, and makes mutual between nail pushing plate locking plate 111 and nail pushing plate protrusion 121
Abutting is more firm, is not susceptible to slipping phenomenon.
Proximal end herein is limited according to industry practice, that is, person close from doctor is proximal end when performing the operation, opposite one
End is distal end.
The stitching unstrument with percussion locking device provided by the present invention is described in detail above.It is used herein
Principle and implementation of the present invention are described for specific example, but the explanation of above example is only intended to help to manage
The principle of the present invention and its core concept are solved, not limiting the scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, without departing from the principle of the present invention, can also to the present invention carry out it is several improvement and repair
Decorations, these improvements and modifications also fall within the scope of protection of the claims of the present invention.
