Description
Technical field
The present invention relates to a kind of can be on multiple positions the chamber mirror Endo-GIA of bidirectional lockingJaw direction adjustment organization, belong to technical field of medical instruments.
Background technology
Chinese invention patent " being applicable to the Endo-GIA of Minimally Invasive Surgery " application number isCN201310263622.9, below summary, for patent 1, discloses a kind of surgical operating instrument,Rotary joint knob drives socket joint synchronously to rotate, and 2 bearing pins in socket joint drive 2 passesBefore and after joint push rod, slide, make 2 articular link plates of executive module inside drive jaw around hingedPin rotates and regulates, and the decorative pearl on top of an official cap of positioning bead embeds socket joint phase under the effect of stage clip elastic forceIn the locating slot of answering, positioning bead blocks socket joint by means of the mode of frictional force and does not rotate, and makes behaviourThe joint knob of doing can remain on a certain gear to realize the location after jaw is turned. In view ofThe structure of positioning bead part is less, and the elastic force of inner stage clip is also less, and the decorative pearl on top of an official cap is spherical, makesOperation joint knob drives the jaw left and right adjusting of stapler light easily. But, in realityIn clinical operation, the jaw of stapler is in the time that turn condition clamping coincide thick organizing, with I-shapedThe elastic pusher of beam feature makes bit closure as actuator, organizes thicker percussion resistance moreGreatly. Larger resistance forces the elastic pusher transversely deforming of 5 stacks to be blocked in turn conditionJaw, in the time that stapler percussion continues, easily form a cross force and make jaw towards the apparatus longitudinal axisDirection is rotated, and its inner elastic pusher of jaw in turn condition also becomes in bendingShape state, the intrinsic strain of elastic pusher also forms a cross force makes jaw vertical towards apparatusDirection of principal axis rotates. Therefore, jaw rotates around swivel pin under two impacts of laterally making a concerted effort,Stapler jaw is towards the backswing of apparatus y direction, or turns round by force under uncertain factor. Now,The elastic force of the inside stage clip of the ripple pearl of control jaw turning location is less, is easily caused jaw and turnsMoving cross force breaks through, and therefore jaw is by articular link plate, joint push rod and the perpendicular pin of dockingOppositely drive socket joint and joint knob and occur trip stop, make originally should keep being still inThe socket joint of a certain gear, the uncontrollable jaw of joint knob location locking. In view of Qiang Jing WicresoftThe particularity of operation, stapler is to be inserted in 2 or 3 tubuloses that are called " trocar " to lead toIn road, doctor's far-end operation apparatus completing and the step technique of traditional operation under television monitoringDifficulty is very large, and any uncertain action all may produce harm. Above-mentioned phenomenon mainly producesHarm is that the jaw rotating involves the tissue that cuts and sew up, and causes staple lineBe shifted with line of cut. Can have influence on the distance between the broken ends of fractured bone and tumour on the one hand, if displacementGreatly, can cause the tumor tissues of a. deflection pathology or canceration, very likely have all incisxal edge sun of ringThe risk of property, causes expanding secondary excision extension; B. while being partial to normal structure one side, it should be protectedThe part of staying is too much excised. On the other hand, the jaw of rotation involves and can impact coincide tissueNail is shaped, and anastomosis staple after percussion is easily loosening or come off, and then causes anastomotic leakage, thisA little risks are not received.
United States Patent (USP) " SURGICALINSTRUMENTWITHARTICULATIONMECHANISM " US2013/0292448A1, below summary, for patent 2, has also disclosedMirror joint, a kind of chamber governor motion. Rotary joint knob make driving bull stick that 2 vertical slots coordinate andUpper fluted disc synchronously rotates, and drives bull stick to drive cam pin to make yoke piece move forward and backward to realize jaw and turnsCurved adjusting. Upper fluted disc under the thrust of multiple wavy springs stack, when the triangle of its end face protrudingDedentition enters in the end face teeth groove of fixed lower tooth disk to engage, and joint knob is maintained atOn a certain gear, to realize the location after jaw is turned. And, for ensureing the effective locking of mechanism,Prevent jaw backswing and oppositely drive driving bull stick, upper fluted disc, joint knob to occur trip stop,Wavy spring need to apply the larger tight upper and lower fluted disc of defeating. As can be seen here, joint knob turnsMoving difficulty, operation effort and feel are stiff, have increased some unfavorable factors to operator. IfWavy spring power is less, still has jaw backswing and cannot locate the possibility of locking.
Obviously, the technical scheme of above-mentioned two patents has some shortcomings and drawback, main manifestationsFor a. easy fatigue failure of the spring in compressive state for a long time. B. the size of spring force is at surgeryDoctor expects that the feel of light operation and mechanism reliability aspect are contradiction points. Patent 1 is adoptedWith the ripple pearl of 2 axis and joint rotation axis line parallel, its inner stage clip elastic force is little, althoughOperating handle is light, but shortcoming is to pull the trigger thick tissue meeting backswing in the jaw of turn condition, goes outShow joint knob trip stop and cannot locate locking stapler jaw, its reliability deficiency. And,If simply increase the elastic force of the inner stage clip of ripple pearl, by the weld strength to swivel head upper and lower coversLong-term is a very large risk in released state. Patent 2 adopts and the same axle of joint knobMultiple wavy spring stacks of line compress upper and lower fluted disc, and rely on the engagement of triangle teeth groove, althoughThe possibility of the larger prevention jaw of spring force backswing is less, but its shortcoming is the triangle teeth groove field of conjugate actionLong-pending large, frictional resistance is large, and required operating physical force is also large, and the upper fluted disc of wavy spring compressionPower is by the direct perception of operator, and therefore the larger operation of wavy spring thrust joint knob is harder.In view of the feel of surgeon's operating apparatus exists biased being difficult to quantitatively, its power value trend is little, andSaid mechanism guarantees that the spring force value trend of not backswing of jaw is large, and this is obviously an outstanding lanceShield point. C. the reverse special delivery that mechanism cannot retardation motion. Above-mentioned patent 1 adopts determining of sphericThe triangle teeth groove that position ripple pearl and patent 2 adopt does not have the one-way of motion, works as spring forceIn less or situation about losing efficacy, cannot effectively stop jaw backswing or stop its oppositely band movable jointKnob rotates and trip stop. D. in view of diameter and patent 2 end faces of the decorative pearl on top of an official cap of patent 1 ripple pearl distributeThe width of teeth groove, is the validity of assurance mechanism, and the gear calibration that apparatus regulates has been subject to structureRestriction, the flexibility of stapler jaw has been subject to restriction, can only be controlled at 2-3 symmetricalGear adjustment movement. In surgical chamber mirror Minimally Invasive Surgery uses, its operating space is narrow and small,The gear that stapler jaw is confined to 2-3 position regulates, and the convenience of its operation has been subject to limitSystem, and in operation, stapler jaw has tissue is caused to unknown wound compared with the adjusting of large spanThe risk of evil. Therefore, based on above-mentioned analysis, the joint governor motion of chamber mirror Endo-GIAAlso need further improvement.
Obviously can be found out by above-mentioned, design a kind of feel of simple in structure, operation joint knobMore light softly the gear of jaw rotation is more and span is little, can guarantee that again jaw is in turningThe joint governor motion of the thick chamber mirror Endo-GIA of organizing effective location locking of state cutting, isThose skilled in the art need to continue the problem of improving and solving.
