In nail-anvil assembly, there are nail anvil and nail anvil frame. Nail anvil can be made one with nail anvil frame. Nail anvil is lineShape, can be both rectilinear, also can be curved. On the surface of nail anvil, be arranged with nail bin in anastomosis staple positionCorresponding anastomosis staple grooving. Multiple anastomosis staple groovings (comprise two be staggered to two rows on the surface of nail anvil more thanRow). On nail anvil frame, there are middle part projection and nearside projection. Clamp hook and nail bin frame are pivotally connected. At nail bin groupware and nail-anvil assemblyAfter mutually closing up, clamp hook is rotated around nail bin frame pivot, make clamp hook hook the middle part projection on nail anvil frame, drive nail binBriquetting on frame is pressed on the nearside projection of nail anvil frame, and the clamped hook of nail bin groupware and nail-anvil assembly is clamped, and will wait to coincideClamp tissue is between nail anvil and nail bin.
As introduced in United States Patent (USP) publicity 20090308909: the pushing away of the firing lock of surgical linear Endo-GIAButton is positioned at the one-sided of nail bin groupware. In the time that the push button promotion slide block of firing lock moves forward in nail bin frame, slipper push pushes awayBar moves forward in nail bin frame, and push rod promotes ejector pin again and tiltedly carves with cutter and move forward in nail bin frame, and ejector pin is tiltedly carved againPromote successively each ejector pin piece releases anastomosis staple in nail bin. Anastomosis staple in nail bin takes the shape of the letter U. When ejector pin piece is by anastomosis stapleIn nail bin, release, the nail tip of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, make two nail legs of the anastomosis staple of U-shapedBend to the anastomosis staple of B shape along grooving, reach and will organize identical operation object. The tissue that coincide will be waited in order to ensure to reachAccurately identical operation object, the push button of firing lock in the time of percussion, need without a break continuously by the anastomosis staple of 80 left and right fromIn nail bin, release, and make two nail legs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, surgical doctor appliesActive force on push button is larger. The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of this styleBe: when nail bin groupware and the clamped hook of nail-anvil assembly clamp and will, in the time that identical clamp tissue is between nail anvil and nail bin, be waited to kissThe impact of the charge-coupled anatomical position of knitting, the position at the push button place of one-sided placement may be not easy to surgical doctor and apply active force and existPush button, thus impact will be waited the accurately identical operation object of tissue of coincideing. As introduced in United States Patent (USP) publicity 20080116244: the pivot of the slide block that the push button of the firing lock of surgical linear Endo-GIA can be in being arranged on nail bin frame rotates. WhenPush button is after the pivot of slide block rotates, and push button both can be given prominence to the left side of nail bin frame, also can give prominence to the right side of nail bin frame,Be convenient to surgical doctor and select the position of the push button that applies active force. The percussion of the surgical linear Endo-GIA of above-mentioned two kinds of stylesThe unsatisfactory place of mechanism is: side-prominent to nail bin frame all the time due to the push button of firing lock, at clamp hook around nail binFrame pivot rotates when nail bin groupware and the clamped hook of nail-anvil assembly are clamped, and outstanding push button affects surgical doctor to clamp hookApply active force, thereby impact will treat that identical tissue is accurately clamped in the operation between nail anvil and nail bin, or cause surgical doctorOperation fatigue. As introduced in United States Patent (USP) publicity 20110155787: the firing lock of surgical linear Endo-GIAPush button can be in being arranged on nail bin frame the pivot of slide block rotate. When push button is after the pivot of slide block rotates, push button both canLeft side to nail bin frame is outstanding, also can give prominence to the right side of nail bin frame. Because push button is positioned at the afterbody of nail bin frame, treat in clampingWhile coincideing the operation of tissue, not any side-prominent to nail bin frame of push button, does not affect surgical doctor clamp hook is applied to effectPower; In push button when operation percussion, be convenient to again surgical doctor and select the position of the push button that applies active force. The surgical thread of this styleThe unsatisfactory place of the firing lock of shape Endo-GIA is: because push button is positioned at the afterbody of nail bin frame, increased surgical threadThe entire length of shape Endo-GIA, making does not have enough operative spaces to offer at the identical tissue for the treatment of of some anatomical positionThe operation of surgical linear Endo-GIA. The firing lock of the surgical linear Endo-GIA of above-mentioned three kinds of styles unsatisfactoryPlace is: the first, and because push button is given prominence to the one-sided of nail bin frame, in the time that push button is pulled the trigger, surgical doctor only can cut at surgical linearThe one-sided active force that applies of stapler, the surgical doctor less to strength, or to cutting the larger operative site of resistance that coincide, exampleAs, the cutting thicker or harder tissue that coincide of waiting that coincide, or cutting the coincideing of this tissue place that waits to coincide while coincideing last operationNail, is just difficult to reach and will waits the accurately identical operation object of tissue of coincideing; The second, because push button is given prominence to the one-sided of nail bin frame,The outstanding position of push button from the point of force application of the slide block in push button and nail bin frame away from, therefore, push button acts on the power formation of slide blockTo cutting coincide useful thrust and useless moment of torsion, the frictional force between moment of torsion increase slide block and nail bin frame and the change of slide blockShape, the resistance thereby the cutting of increase firing lock coincide; The 3rd, in the time that push button starts to pull the trigger, or in the time that push button completes percussion, orWhen push button returns while resetting, firing lock both insentience, also voiceless sound is reminded the variation that operation technique personnel pull the trigger process, therebyMay cause firing lock operate miss. Therefore the firing lock of surgical linear Endo-GIA also needs to improve.
Obviously can be found out by above-mentioned, design now a large amount of not surgical linear Endo-GIAs in specie, andAnd the development work of the firing lock of new surgical linear Endo-GIA is still continuing, to using in a large number in the world every yearSurgical linear Endo-GIA be improved further, reach more convenient, more laborsaving while use, more reliable, the operation of being more convenient forDoctor applies active force and does not reduce the surgical effect of the operation accommodation of surgical linear Endo-GIA.
Summary of the invention
The object of the invention is to propose a kind of firing lock of surgical linear Endo-GIA, realize two push buttons respectivelyDraw the left and right sides at nail bin frame in. Both can nail bin frame the push button in left side launch to the left side of nail bin frame, also can nail bin frameThe push button on right side launches to the right side of nail bin frame, and two push buttons that can also nail bin frame both sides are respectively to the left and right sides of nail bin frameLaunch. Thereby both reach in the time of the operation clamping wait the tissue that coincide, not any side-prominent to nail bin frame of push button, does not affect handArt doctor applies active force to clamp hook; Again in push button when operation percussion, be convenient to surgical doctor and select to apply the push button of active forcePosition; Also do not increase the entire length of surgical linear Endo-GIA, the operation that does not reduce surgical linear Endo-GIA is suitableAnswer the surgical effect of scope.
Another object of the present invention is to propose a kind of firing lock of surgical linear Endo-GIA, realize push button outstandingPosition from the point of force application of the slide block in push button and nail bin frame close to, reduce as far as possible between the slide block and nail bin frame that moment of torsion producesFrictional force and the distortion of slide block, thereby reach the coincide result of use of resistance of the cutting that reduces firing lock.
A further object of the present invention is to propose a kind of firing lock of surgical linear Endo-GIA, realizes the near of slide blockThe flexible projection of side, when push button is in the time pulling the trigger state or when push button is in the time completing percussion state, maybe ought start to push awayWhen button, the resistance that change elastic projection moves is also sounded, thereby reaches firing lock by feel and sound double-remindingOperation technique personnel pull the trigger the result of use of the variation of process.
At present, known surgical linear Endo-GIA is made up of nail bin groupware, nail-anvil assembly and clamp hook.
In nail bin groupware, there is nail bin, the nail bin frame of nail bin is installed and is arranged on the firing lock in nail bin frame. Nail bin is lineShape, can be both rectilinear, also can be curved. Ejector pin piece and anastomosis staple are installed in nail bin. Multiple anastomosis staplesBe staggered to two rows in nail bin more than, (comprise two rows). On nail bin frame, there is briquetting.
In nail-anvil assembly, there are nail anvil and nail anvil frame. Nail anvil can be made one with nail anvil frame. It is linear that nail anvil is, and can be bothRectilinear, also can be curved. On the surface of nail anvil, be arranged with coincide corresponding with anastomosis staple position in nail binNail grooving. More than being staggered to two rows on the surface of nail anvil, multiple anastomosis staple groovings (comprise two rows). On nail anvil frameThere are middle part projection and nearside projection.
Clamp hook and nail bin frame are pivotally connected. After nail bin groupware and nail-anvil assembly close up mutually, by clamp hook around nail binFrame pivot rotates, and makes clamp hook hook the middle part projection on nail anvil frame, drives the briquetting on nail bin frame to be pressed in the near of nail anvil frameOn side projection, the clamped hook of nail bin groupware and nail-anvil assembly is clamped.
Task of the present invention is achieved through the following technical solutions:
The firing lock of surgical linear Endo-GIA of the present invention is tiltedly carved and cutter by push button, slide block, push rod, ejector pinComposition. Two push buttons lay respectively at the left and right sides of nail bin frame. Two push buttons have respectively pivot hole. Slide block is constrained on nail bin frameSlide in interior front and back. There is a pivot at slide block middle part. After two upper and lower overlapping placements of push button, be enclosed within the same of slide block by pivot holeOn pivot. Two push buttons can rotate around the pivot of slide block separately. When each push button is after the pivot of slide block rotates, push button is to nailLaunch in the outside of storehouse frame. Both can nail bin frame the push button in left side launch to the left side of nail bin frame, also can nail bin frame right side push awayButton launches to the right side of nail bin frame, and two push buttons of all right nail bin frame both sides launch to the left and right sides of nail bin frame respectively. WhenWhen push button promotion slide block moves forward in nail bin frame, slipper push push rod moves forward in nail bin frame, and push rod promotes againNail is tiltedly carved with cutter and is moved forward in nail bin frame, ejector pin tiltedly carve promote successively again each ejector pin piece by anastomosis staple in nail binRelease.
Like this, two push buttons draw in respectively in the left and right sides of nail bin frame, both can nail bin frame the push button in left side to nail binLaunch in the left side of frame, and push button that also can nail bin frame right side launches to the right side of nail bin frame, can also nail bin frame both sides twoPush button launches to the left and right sides of nail bin frame respectively. In the time that push button promotion slide block moves forward in nail bin frame, slipper push pushes awayBar moves forward in nail bin frame, and push rod promotes ejector pin again and tiltedly carves with cutter and move forward in nail bin frame, and ejector pin is tiltedly carved againPromote successively each ejector pin piece releases anastomosis staple in nail bin. Firing lock is clamping in the time coincideing the operation of organizing, push buttonNot any side-prominent to nail bin frame, does not affect surgical doctor clamp hook is applied to active force. Firing lock is pulled the trigger at push buttonWhen operation, surgical doctor can coincide and treat thickness and the soft or hard of identical tissue according to cutting, or according to cutting last behaviour of coincideingWhile work, whether this tissue place that waits to coincide has anastomosis staple, or according to the strength size of surgical doctor, selects one hand or both hands to apply workThe position of push button firmly. Firing lock also reaches the entire length that does not increase surgical linear Endo-GIA, does not reduce surgeryThe surgical effect of the operation accommodation of linear Endo-GIA.
Two push buttons of surgical linear Endo-GIA of the present invention can have respectively pivot hole and deep-slotted chip breaker, slide block far-endThe wing that launch the left and right sides that can oriented nail bin frame. When each push button is after the pivot of slide block rotates, push button is to nail bin frameLaunch in outside, and the deep-slotted chip breaker of push button is inserted on the wing of slide block, and the wing that push button promotes slide block by deep-slotted chip breaker makes slide block at nail binIn frame, move forward, slide block promotes push rod again and moves forward in nail bin frame, and push rod promotes ejector pin again and tiltedly carves with cutter at nailIn the frame of storehouse, move forward, ejector pin is tiltedly carved and is promoted successively each ejector pin piece again anastomosis staple is released in nail bin.
Like this, the wing that promotes slide block by deep-slotted chip breaker due to push button moves forward slide block in nail bin frame, therefore pushes awayThe outstanding position of button from the point of force application of the slide block in push button and nail bin frame close to, can reduce as far as possible slide block that moment of torsion produces andFrictional force between nail bin frame and the distortion of slide block, thus reach the coincide result of use of resistance of the cutting that reduces firing lock.
The pivot nearside of slide block can have chute. Two push buttons can have respectively projection. The left and right two of the near-end of nail bin frameSide can be jagged respectively. In the time that each push button is drawn close the side of nail bin frame, the projection of push button is positioned at the chute of slide block. When respectivelyIndividual push button is in the time that the pivot rotation of slide block launches to the outside of nail bin frame, and the projection of push button shifts out slide block from the indentation, there of nail bin framePivot nearside chute and lean against on the side of nail bin frame. When the push button that promotes to launch to the outside of nail bin frame moves forwardTime, the push button launching to the outside of nail bin frame promotes slide block and moves forward in nail bin frame, does not launch to the outside of nail bin frameThe projection of push button is constrained in the chute of pivot nearside of slide block and moves forward by nail bin frame. When launch in the outside to nail bin framePush button while moving backward, the projection of the push button launching to the outside of nail bin frame leans against on the side of nail bin frame, stop push button aroundThe pivot of slide block rotates, thereby the push button band movable slider launching to the outside of nail bin frame is moved backward in nail bin frame.
In the chute of the pivot of slide block, can there is projection. Can be fluted on the projection of push button. When push button is drawn close nail bin frameSide time, the groove on the projection of push button is stuck on the projection of chute of slide block, and push button is constrained on slide block. When pushing awayMoving push button is in the time that the pivot rotation of slide block launches to the outside of nail bin frame, and the groove on the projection of push button departs from the chute of slide blockThe constraint of projection.
Can there be key the both sides of slide block. Can there be keyway the inner side of nail bin frame. The key of slide block is constrained on nail bin frame inner sideKeyway in slide block is constrained in nail bin frame move forward and backward.
The nearside of slide block can flexible projection. The near-end of the bottom of nail bin frame and middle part can be porose respectively. Work as push buttonIn in the time pulling the trigger state, the elastic projection of slide block springs in the proximal orifice of bottom of nail bin frame, and slide block is constrained in to nail bin frameNear-end. When push button is in the time completing percussion state, the elastic projection of slide block springs in the mider hole of bottom of nail bin frame, will slidePiece constrains in the middle part of nail bin frame. In the time starting to promote push button, act on making every effort to overcome on push button and take the hole pair of the bottom of nail bin frameThe constraint of the elastic projection of slide block, makes push button promote slide block and moves forward and backward in nail bin frame.
Like this, when push button is in the time pulling the trigger state or when push button is in the time completing percussion state, maybe ought start to push awayWhen button, concurrent the speaking of resistance that the firing lock of surgical linear Endo-GIA of the present invention moves by changing elastic projectionSound, pulls the trigger the use effect of the variation of process thereby reach firing lock by feel and sound double-reminding operation technique personnelReally.

Introduce in detail knownly according to above-mentioned, compare with existing various surgical linear Endo-GIAs, of the present invention outsideThe firing lock of the linear Endo-GIA of section has following technique effect:
The push button of the firing lock of more existing surgical linear Endo-GIAs is positioned at the one-sided of nail bin groupware. Work as percussionWhen the push button promotion slide block of mechanism moves forward in nail bin frame, slipper push push rod moves forward in nail bin frame, and push rod againPromote ejector pin and tiltedly carve with cutter and move forward in nail bin frame, ejector pin tiltedly carve promote successively again each ejector pin piece by anastomosis staple fromIn nail bin, release. Anastomosis staple in nail bin takes the shape of the letter U. When ejector pin piece is released anastomosis staple in nail bin, by the anastomosis staple of U-shapedNail tip is pressed on the grooving of nail anvil, makes two of anastomosis staple nail legs of U-shaped bend to the anastomosis staple of B shape along grooving,Reach and will organize identical operation object. The accurately identical operation object of tissue of coincideing, firing lock will be waited in order to ensure to reachPush button need continuously the anastomosis staple of 80 left and right is released in nail bin without a break in when percussion, and make the anastomosis staple of U-shapedTwo nail legs bend to the anastomosis staple of B shape along grooving, the active force that surgical doctor is applied on push button is larger. ThisThe unsatisfactory place of the firing lock of the surgical linear Endo-GIA of kind of style is: when nail bin groupware and nail-anvil assembly are pressed from both sidesTight hook clamps will be in the time that identical clamp tissue be between nail anvil and nail bin, is treated the impact of the anatomical position of identical tissue, one-sidedThe position at the push button place of placing may be not easy to surgical doctor and apply active force at push button, thereby impact will be waited to coincide, tissue is accurateReally identical operation object. The push button of the firing lock of existing other surgical linear Endo-GIAs can be around being arranged on nailThe pivot of the slide block in the frame of storehouse rotates. When push button is after the pivot of slide block rotates, push button both can be given prominence to the left side of nail bin frame,Also can give prominence to the right side of nail bin frame, be convenient to surgical doctor and select to apply the position of push button of active force. Above-mentioned two kinds of stylesThe unsatisfactory place of firing lock of surgical linear Endo-GIA be: because the push button of firing lock is all the time to nail bin frameOne side-prominent, rotate when the clamped hook of nail bin groupware and nail-anvil assembly is clamped around nail bin frame pivot at clamp hook, give prominence toPush button affect surgical doctor clamp hook applied to active force, thereby impact will be treated identical tissue and accurately be clamped in nail anvil and nail binBetween operation, or cause the operation fatigue of surgical doctor. The existing percussion lock that also has some surgical linear Endo-GIAsThe push button of structure can be in being arranged on nail bin frame the pivot of slide block rotate. When push button is after the pivot of slide block rotates, push button bothCan give prominence to the left side of nail bin frame, also can give prominence to the right side of nail bin frame. Because push button is positioned at the afterbody of nail bin frame, at folderTightly in the time of the operation of the tissue that coincide, not any side-prominent to nail bin frame of push button, does not affect surgical doctor clamp hook is appliedActive force; In push button when operation percussion, be convenient to again surgical doctor and select the position of the push button that applies active force. Outside this styleThe unsatisfactory place of the firing lock of the linear Endo-GIA of section is: because push button is positioned at the afterbody of nail bin frame, outside having increasedThe entire length of the linear Endo-GIA of section, making does not have enough operative spaces to carry at the identical tissue for the treatment of of some anatomical positionSupply with the operation of surgical linear Endo-GIA. Making us not of the firing lock of the surgical linear Endo-GIA of above-mentioned three kinds of stylesSatisfied place is: the first, and because push button is given prominence to the one-sided of nail bin frame, in the time that push button is pulled the trigger, surgical doctor only can be at surgical linearThe one-sided active force that applies of Endo-GIA, the surgical doctor less to strength, or to cutting the larger Surgery of resistance that coincidePosition, for example, the cutting thicker or harder tissue that coincide of waiting that coincide, or cutting this tissue place that waits to coincide while coincideing last operationAnastomosis staple, is just difficult to reach and will waits the accurately identical operation object of tissue of coincideing; The second, because push button is dashed forward to the one-sided of nail bin frameGo out, the outstanding position of push button from the point of force application of the slide block in push button and nail bin frame away from, therefore, push button acts on the power shape of slide blockThe identical useful thrust of cutting and useless moment of torsion in pairs, the frictional force between moment of torsion increase slide block and nail bin frame and the change of slide blockShape, the resistance thereby the cutting of increase firing lock coincide; The 3rd, in the time that push button starts to pull the trigger, or in the time that push button completes percussion, orWhen push button returns while resetting, firing lock both insentience, also voiceless sound is reminded the variation that operation technique personnel pull the trigger process, therebyMay cause firing lock operate miss. Therefore the firing lock of existing surgical linear Endo-GIA also needs to improve.
Two push buttons of the firing lock of surgical linear Endo-GIA of the present invention rotate around the pivot of slide block separately. WhenEach push button is after the pivot of slide block rotates, and push button launches to the outside of nail bin frame. Both can nail bin frame the push button in left side to nailLaunch in the left side of storehouse frame, and push button that also can nail bin frame right side launches to the right side of nail bin frame, can also nail bin frame both sides twoIndividual push button launches to the left and right sides of nail bin frame respectively. In the time that push button promotion slide block moves forward in nail bin frame, slipper pushPush rod moves forward in nail bin frame, and push rod promotes ejector pin again and tiltedly carves with cutter and move forward in nail bin frame, and ejector pin is tiltedly carvedPromote successively each ejector pin piece releases anastomosis staple in nail bin again. Compare with existing surgical linear Endo-GIA, thisThe firing lock of the surgical linear Endo-GIA of invention both reached and was clamping in the time coincideing the operation of organizing, and push button is not to nail binFrame any one side-prominent, does not affect surgical doctor clamp hook is applied to active force; Again in push button when operation percussion, surgical doctorCan also coincide and wait coincide thickness and the soft or hard of tissue according to cutting, or this waits the group of coincideing while coincideing last operation according to cuttingWhether the place of knitting has anastomosis staple, or according to the strength size of surgical doctor, selects one hand or both hands to apply the position of the push button of active forcePut; Also do not increase the entire length of surgical linear Endo-GIA, the operation that does not reduce surgical linear Endo-GIA adapts to modelThe surgical effect of enclosing.
Two push buttons of the firing lock of surgical linear Endo-GIA of the present invention have respectively pivot hole and deep-slotted chip breaker, slidingThe wing that launch the left and right sides of the oriented nail bin frame of piece far-end. When each push button is after the pivot of slide block rotates, push button is to nail bin frameOutside launch, the deep-slotted chip breaker of push button is inserted on the wing of slide block, the wing that push button promotes slide block by deep-slotted chip breaker is being followed closely slide blockIn the frame of storehouse, move forward, slide block promotes push rod again and moves forward in nail bin frame, and push rod promotes ejector pin again and tiltedly carves with cutter and existIn nail bin frame, move forward, ejector pin is tiltedly carved and is promoted successively each ejector pin piece again anastomosis staple is released in nail bin. Outside existingThe linear Endo-GIA of section is compared, because the push button of the firing lock of surgical linear Endo-GIA of the present invention passes through arcGroove promotes the wing of slide block slide block is moved forward in nail bin frame, and therefore the outstanding position of push button is from the cunning in push button and nail bin frameThe point of force application of piece is nearer, can reduce as far as possible moment of torsion produce slide block and nail bin frame between frictional force and the change of slide blockShape, thus reach the coincide result of use of resistance of the cutting that reduces firing lock.
The firing lock of surgical linear Endo-GIA of the present invention, when push button is in the time pulling the trigger state, the bullet of slide blockProperty projection springs in the proximal orifice of bottom of nail bin frame, slide block is constrained in to the near-end of nail bin frame; When push button is in completing percussionWhen state, the elastic projection of slide block springs in the mider hole of bottom of nail bin frame, slide block is constrained in to the middle part of nail bin frame; When openingBegin to promote when push button, act on the constraint of the hole of bottom that making every effort to overcome on push button the take nail bin frame elastic projection to slide block, makePush button promotes slide block and moves forward and backward in nail bin frame. Therefore, when push button in hitting in completing in the time pulling the trigger state or when push buttonSend out when state, maybe in the time starting to promote push button, compare with existing surgical linear Endo-GIA, surgical linear of the present inventionThe resistance that the firing lock of Endo-GIA moves by change elastic projection is also sounded, and passes through thereby reach firing lockFeel and sound double-reminding operation technique personnel pull the trigger the result of use of the variation of process.
Surgeon is in the time using surgical linear Endo-GIA of the present invention, and two push buttons of firing lock draw in respectivelyIn the left and right sides of nail bin frame, both can nail bin frame the push button in left side launch to the left side of nail bin frame, also can nail bin frame right sidePush button launch to the right side of nail bin frame, two push buttons that can also nail bin frame both sides are respectively to the left and right sides exhibition of nail bin frameOpen. Thereby reach in the time of the operation clamping wait the tissue that coincide, not any side-prominent to nail bin frame of push button, not affecting operation doctorTeacher applies active force to clamp hook; In the time of push button percussion operation, the resistance of firing lock is less, and surgical doctor can also be according to cuttingCutting coincide waits coincide thickness and the soft or hard of tissue, or whether this tissue place that waits to coincide has kiss while coincideing last operation according to cuttingDowel, or according to the strength size of surgical doctor, select one hand or both hands to apply the position of the push button of active force; Outside also not increasingThe entire length of the linear Endo-GIA of section, does not reduce the surgical effect of the operation accommodation of surgical linear Endo-GIA.When push button is in the time pulling the trigger state or when push button is in the time completing percussion state, maybe in the time starting to promote push button, of the present inventionThe resistance that the firing lock of surgical linear Endo-GIA moves by change elastic projection is also sounded, thereby reaches percussionThe result of use of the variation of process is pulled the trigger by feel and sound double-reminding operation technique personnel by mechanism.
