The work process of whole device described below:
When performing the operation, inserting internal after first being closed by the distal jaw assembly 1 of intracavity Endo-GIA, now joint is not
Turn to, keep straight, it is simple to apparatus inserts and seals, and after entering body cavity, distal jaw assembly 1 is opened, according to actual operation need
Want, carry out joint course changing control.
In the steering control device of joint, turn to gear piece 11 will rotate with joint steering knob 3.Turn to right slide block 14
Cylindrical boss 30 is positioned in the U-type groove 2 25 turning to gear piece 11, and the cylindrical boss 32 of port slide block 13 positions
In the U-type groove 1 turning to gear piece 11, initial position is shown in Figure 11.The tip 35 of card article resilience drive block 12 is stuck in and turns to gear piece
In the tooth root of the arc teeth portion 29 of 11.Steering connections card article 20 under the spring effect of spring 19 by the point of steering connections card article 20
End 38 withstands on the tooth root of arc teeth portion 52 of steering connections 21, limits the rotation of steering connections 21, i.e. limits turning of joint
Dynamic, lockable angle simultaneously.
Turn to gear piece 11 when rotating counterclockwise by Figure 12 direction of arrow with hands, turn to the arc teeth portion 29 of gear piece 11 to apply
To the thrust that the tip 35 of card article resilience drive block 12 is certain, card article resilience drive block 12 is made to retreat (side to the right in Figure 12
To), hook sheet 17 by card article rollback and steering connections card article 20 is pulled back (in Figure 12 direction) to the right, make steering connections card article
20 disengage with steering connections 21, when turning to gear piece 11 to rotate α angle, turn to the U-type groove 2 25 of gear piece 11, the side of U-type groove 1
Wall just withstands the cylindrical boss 32 turning to the cylindrical boss 30 of right slide block 14, port slide block 13, turns to gear piece
11 utilize U-type groove 1, the sidewall of U-type groove 2 25 to be applied to port slide block 13 thrust, are applied to turn to right slide block 14 pulling force,
Port hook sheet 15 and turn to right hook sheet 16 by port slide block 13, turn to right slide block 14 pretightning force and do not move, such as Figure 12
Shown in Figure 13 I partial enlarged drawing.With reference to Figure 14, being rotated further joint steering knob 3, now steering connections 21 is by port
Hook the thrust (B direction in Figure 14) in sheet 15 direction and turn to the pulling force (A direction in Figure 14) of right hook sheet 16, steering connections 21 inverse time
(it should be noted that port hooks sheet 15 and turns to right hook sheet 16 is resilient, thrust is the most inoperative, main in pin rotation
If pulling force makes steering connections 21 turn to), now the firmly steering connections card article 20 of the tooth top on steering connections 21 makes it without falling into turning
In the tooth root in joint 21, as shown in II partial enlargement of Figure 15.If now release joint steering knob 3, port hooks sheet
15 and turn to right hook sheet 16 to lose pretightning force, now steering connections 21 will be rotated further 38 turns of the tip making steering connections card article 20
Entering in the tooth root of steering connections 21, steering angle is locked in herein.If not discharging joint steering knob 3, steering connections card article
The tip 38 of 20 will not snap in the tooth root of steering connections 21 all the time, can realize the continuous rotation in joint.
Port hooks sheet 15 and turns to right hook sheet 16 to be not limited to rigid material to make, it is also possible to be that flexible material is made.Adopt
When using rigid material, port hooks sheet 15 and turns to right hook sheet 16 is elongated structural member.
By the rotation of joint steering knob 3, drive the rotation turning to gear piece 11, turn to gear piece 11 profile of tooth by mechanics meter
Calculation and Analysis, makes the least can the realization of joint steering knob 3 rotatory force rotate, promotes card article resilience drive block 12 to move along a straight line, turn
Hook sheet 15 to the left and turn to right hook sheet 16 to pull steering connections 21 to rotate, i.e. realizing joint go to action, turn when being applied to joint
When the power of knob 3 is cancelled, steering connections card article 20 snaps in the tooth root of steering connections 21 under spring force, limits and turns
Rotation to joint 21, it is achieved joint steering angle locks, it is possible to realize continuous cradle head steering knob 3, it is achieved different
Joint steering angle.Angle can position, and simple in construction is safe and reliable.
Turning to angle design between the arc teeth portion 29 of gear piece 11 and most advanced and sophisticated 35 to ensure will not self-locking.Steering connections 21
Between arc teeth portion 52 and most advanced and sophisticated 38 angle design want can self-locking, therefore can realize when joint turns to laborsaving, turn to rear angle
Lockable.
The above only to preferred embodiment of the present utility model, is not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.Every in claim of the present utility model
In the range of restriction, any modification, equivalent substitution and improvement etc. done, all should be within protection domain of the present utility model.
