Description
Technical field
It can be adjusted in the jaw direction of the hysteroscope Endo-GIA of bidirectional locking on multiple positions the present invention relates to a kind of
Mechanism, belong to technical field of medical instruments.
Background technology
Chinese invention patent《Suitable for the Endo-GIA of Minimally Invasive Surgery》Application No. CN201310263622.9, below
To sketch as patent 1, disclose a kind of surgical operating instrument, rotary joint knob drives socket joint synchronous axial system, and 2 in socket joint
Root bearing pin drives 2 joint push rods to slide back and forth, and makes 2 articular link plates inside executive module drive jaw to turn around swivel pin
Dynamic regulation, also, the decorative pearl on top of an official cap of positioning bead, in the corresponding locating slot of embedded socket joint in the presence of stage clip elastic force, positioning bead relies on
The mode of frictional force is blocked socket joint and not rotated so that the joint knob of operation may remain on a certain gear to realize jaw
Positioning after turning.In view of the structure of positioning bead part is smaller, the elastic force of internal stage clip is also smaller, and the decorative pearl on top of an official cap is spherical so that behaviour
Making joint knob drives the jaw left and right adjusting of stapler light easily.But in the clinical operation of reality, the pincers of stapler
For mouth when turn condition clamps and coincide thick tissue, the elastic pusher with I-beam feature closes bit as actuator
Close, organize thicker percussion resistance bigger.Larger resistance forces the elastic pusher transversely deforming of 5 superpositions to be blocked in turning shape
The jaw of state, when stapler, which fires, to be continued, easily forming a cross force makes jaw be rotated towards apparatus y direction, and is in
Its internal elastic pusher of the jaw of turn condition is also at flexural deformation state, and the intrinsic elastic deformation of elastic pusher is also formed
One cross force makes jaw be rotated towards apparatus y direction.Therefore, jaw turns under the influence of two transverse directions are made a concerted effort around swivel pin
Dynamic, i.e., stapler jaw is towards apparatus y direction backswing, or is turned round by force under uncertain factor.Now, jaw is controlled to turn
The elastic force of the inside stage clip of the ripple pearl of positioning is smaller, be easily caused jaw rotation cross force break through, therefore jaw pass through it is right
Articular link plate, joint push rod and the perpendicular pin connect reversely drives socket joint and joint knob and trip stop occurs, originally should make
When socket joint of the remains stationary in a certain gear, the uncontrollable jaw positioning locking of joint knob.In view of hysteroscope Minimally Invasive Surgery
Particularity, stapler are inserted into 2 or 3 and are called in the tubular conduit of " trocar ", and doctor distally grasps under television monitoring
Make apparatus and completion is very big with the step technical difficulty of traditional operation, all there may be harm for any uncertain action.It is above-mentioned
The jaw that harm caused by phenomenon is main is to rotate involves to the tissue for cutting and suturing, and causes staple line and cuts
Secant shifts.On the one hand the distance between the broken ends of fractured bone and tumour are influenced whether, if displacement is big, a. deviation lesions or cancer can be caused
The tumor tissues of change, it is most likely that the risk of ring week positive margin be present, cause to expand secondary excision extension；B. it is inclined to normal group
The part that it should retain when knitting side is excessively cut off.On the other hand, the jaw of rotation involves on tissue can influence anastomosis staple
Anastomosis staple after shaping, and percussion easily loosens or come off, and then causes anastomotic leakage, and these risks are not received.
United States Patent (USP)《SURGICAL INSTRUMENT WITH ARTICULATION MECHANISM》US2013/
0292448 A1, described briefly below is patent 2, also discloses a kind of hysteroscope joint governor motion.Rotary joint knob makes 2 vertical slots
The driving bull stick of cooperation and upper fluted disc synchronous axial system, driving bull stick drive cam pin to make yoke block movable to realize that jaw is turned
Regulation.Upper fluted disc is under the thrust that multiple wavy springs are superimposed, when the triangle double wedge of its end face falls into fixed lower tooth
Engaged in the end face teeth groove of disk so that joint knob is maintained on a certain gear, to realize the positioning after jaw turning.And
And to ensure the effective locking of mechanism, prevent jaw backswing and reversely drive driving bull stick, upper fluted disc, joint knob to occur
Trip stop, wavy spring, which needs to apply, larger forces tight upper and lower fluted disc.As can be seen here, joint knob is difficult, and operation is laborious
And feel is stiff, some unfavorable factors are added to operator.If wavy spring power is smaller, still have jaw backswing and nothing
The possibility of legal position locking.
Obviously, the technical scheme of above-mentioned two patent has some shortcomings and drawback, is mainly shown as that a. is chronically at pressure
The easy fatigue failure of spring of contracting state.B. the size of spring force it is expected that the feel of light operation and mechanism are reliable in surgeon
Property aspect be a contradiction point.Patent 1 is using 2 axis and the ripple pearl of joint knob diameter parallel, its internal stage clip elastic force
Small, although operating handle is light, shortcoming is the jaw percussion thick tissue meeting backswing in turn condition, joint knob occurs and jumps
Shelves and locking stapler jaw can not be positioned, its reliability deficiency.Also, if simply increase the bullet of stage clip inside ripple pearl
Power, it is a very big risk that released state will be chronically to the weld strength of swivel head upper and lower covers.Patent 2 uses and joint
Multiple wavy springs superposition of the same axis of knob compresses upper and lower fluted disc, and by the engagement of triangle teeth groove, although spring force is bigger
Prevent the possibility of jaw backswing smaller, but its shortcoming is that triangle teeth groove area of contact is big, and frictional resistance is big, required operating physical force
Also it is big, and the power of the upper fluted disc of wavy spring compression is directly perceived by operator, therefore the bigger operation of wavy spring thrust is closed
It is harder to save knob.In view of surgeon operate apparatus feel exist it is biased be difficult to quantitative, its force value tends to small, and above-mentioned machine
Structure ensures that the spring force value of jaw not backswing tends to big, and this is clearly a prominent contradiction point.C. mechanism can not retardation motion
Reverse special delivery.The triangle teeth groove that above-mentioned patent 1 is used using the positioning ripple pearl and patent 2 of spheric is all without motion
One-way, in the case that spring force is smaller or fails, it can not effectively prevent jaw backswing or prevent its reversely band movable joint rotation
Button rotates and trip stop.D. in view of the width of the diameter of the decorative pearl on top of an official cap of the ripple pearl of patent 1 and the end face of patent 2 distribution teeth groove, is assurance mechanism
Validity, the gear indexing of apparatus regulation receives the limitation of structure, and the flexibility of stapler jaw receives restriction, can only
Control is in 2-3 symmetrical gear regulation motions.In surgical hysteroscope Minimally Invasive Surgery in use, its operating space is narrow and small,
Stapler jaw is confined to the gear regulation of 2-3 position, and its convenience operated is restricted, also, is coincide in performing the operation
Regulation of the device jaw compared with large span has the risk that unknown injury is caused to tissue.Therefore, based on above-mentioned analysis, hysteroscope cutting
The joint governor motion of stapler also needs further to improve.
By above-mentioned it will be clear that a kind of feel simple in construction, operation joint knob of design is more light soft, pincers
Mouthful gear rotated is more and span is small, and and can ensures that jaw effectively positions the hysteroscope of locking in turn condition cutting thick tissue and cut
The joint governor motion of stapler is cut, is that those skilled in the art need lasting improvement and solved the problems, such as.
The content of the invention
