Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.
As Figure 1-3, this utility model is provided with position fixing handle 1, flexible handle 2, nail supporting base support 3 and cutting assembly frame
4.Position fixing handle 1 is fixing with nail supporting base support 3 to be connected, and flexible handle 2 is connected with cutting assembly frame 4, by beak hook 5 and locating shaft
6 are connected with nail supporting base support 3.Nail supporting base support 3 lower surface is provided with nail supporting base 17.Cutting assembly frame 4 is provided with push rod 7, push rod 7 end
End is provided with percussion button 8.
As shown in figs. 1 and 4, flexible handle 4 is provided with tripper and shell fragment.Tripper includes solving lock-switch 10, unlocking
Switch spring 11, lock pin 12 and snap close 13；Lock pin 12 one end with solve lock-switch 10 be connected, contact with snap close 13, the other end with
Unlock switch spring 11 to connect.
As shown in Figures 4 and 5, it is provided with percussion button boss 9 bottom percussion button 8.Push rod 7 end is additionally provided with percussion button fixing device
With arc guide barrel 14, percussion button fixing device includes bayonet lock 15 and bayonet lock spring 16.
As Figure 6-9, cutting assembly frame 4 is additionally provided with nail bin groupware 18, and nail bin groupware 18 is provided with and dismountable protects nail-plate
19, anti-skid structure and suturing nail 22.Anti-skid structure includes anti-skid stud 20, cascaded surface 21 and antiskid groove 23, can make near tissue
The pressure of 24 incisxal edge sides increases, increasing friction force then, plays restriction tissue 24 slidings on the basis of not destroying tissue 24
Effect.Stitching thread extends to inside jaw, and both sides respectively extend a suturing nail 22, makes the tissue being extruded within jaw
24 also can be sewn.
Below work process of the present utility model is described in detail.
Holding position fixing handle 1, switch 10 with hands being unlocked by pressing, unlock switch spring 11 and compressed, lock pin 12 is away from snap close
13, under the effect of the internal shell fragment of flexible handle 2, flexible handle 2 automatically opens up along arrow C direction.Nail supporting base support 3 and cutting
Jaw between assembly frame 4 opens the most automatically, and beak hook 5 hooks on locating shaft 6, and anastomat is in center lock position (such as Fig. 2).
Take off and protect nail-plate 19, now can clamp tissue 24.After tissue 24 is had good positioning, firmly Compressive activities handle 2, lock pin 12 snaps in
In snap close 13, can hear " clicker " prompting sound after putting in place, now flexible handle 2 locks, and jaw closes.Period push rod 7 end
Percussion button 8 is in initial position (such as Fig. 1) all the time, maintains static under the effect of bayonet lock 15 and bayonet lock spring 16, but applies relatively
Little revolving force can make its arcuately guide groove 14 rotate (such as Fig. 5).Operating habit according to doctor rotates percussion button 8, fires button
Boss 9 arcuately can turn to required I side or II side by guide groove 14, promotes forward percussion button 8 to stop, i.e. to cutting terminated line with hands
