Can know that according to above-mentioned detailed introduction compare with existing various surgical linear Endo-GIAs, the firing lock of the surgical linear Endo-GIA of this utility model 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.When the push button promotion slide block of firing lock moves forward in the nail bin frame; Slide block promotes push rod and in the nail bin frame, moves forward; Push rod promotes ejector pin again and tiltedly carves with cutter and in the nail bin frame, move forward, and ejector pin is tiltedly carved and promoted each ejector pin piece more successively anastomosis staple is released in nail bin.Anastomosis staple in nail bin takes the shape of the letter U.When the ejector pin piece is released anastomosis staple in nail bin, the nail point of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, make two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, reach the operation purpose that tissue is coincide.In order to guarantee to reach with waiting the accurately identical operation purpose of tissue of coincideing; Anastomosis staple about the push button of firing lock needs without a break continuously with 80 when percussion is released in nail bin; And two of anastomosis staple nail lower limbs that make U-shaped bend to the anastomosis staple of B shape along grooving, and the active force that surgical doctor is applied on the push button is bigger.The dissatisfied place of making us of the firing lock of the surgical linear Endo-GIA of this style is: when the clamped hook of nail bin groupware and nail-anvil assembly clamps will treat that identical clamp tissue is between nail anvil and nail bin the time; Treated the influence of the anatomical position of identical tissue; The position at the push button place of one-sided placement possibly be not easy to surgical doctor and apply active force at push button, the accurate operation purpose of coincideing of tissue thereby influence will be waited to coincide.The push button of the firing lock of existing other surgical linear Endo-GIAs can be around the pivoted of the slide block in being installed in the nail bin frame.When push button after the pivoted of slide block, push button both can be outstanding to the left side of nail bin frame, also can be outstanding to the right side of nail bin frame, be convenient to the position that surgical doctor selects to apply the push button of active force.The dissatisfied place of making us of the firing lock of the surgical linear Endo-GIA of above-mentioned two kinds of styles is: because the push button of firing lock side-prominent to the nail bin frame all the time; At clamp hook when nail bin frame pivoted makes that the clamped hook of nail bin groupware and nail-anvil assembly clamps; Outstanding push button influences surgical doctor clamp hook is applied active force; Tissue accurately is clamped in the operation between nail anvil and the nail bin thereby influence will be waited to coincide, or causes the operation fatigue of surgical doctor.It is existing that the push button of the firing lock of some surgical linear Endo-GIAs can be around the pivoted of the slide block in being installed in the nail bin frame in addition.When push button after the pivoted of slide block, push button both can be outstanding to the left side of nail bin frame, also can be outstanding to the right side of nail bin frame.Because push button is positioned at the afterbody of nail bin frame, when clamping waited to coincide the operation of tissue, push button is any side-prominent to the nail bin frame not, do not influence surgical doctor clamp hook is applied active force; When push button percussion operation, be convenient to the position that the surgical doctor selection applies the push button of active force again.The dissatisfied place of making us of the firing lock of the surgical linear Endo-GIA of this style is: because push button is positioned at the afterbody of nail bin frame; Increased the entire length of surgical linear Endo-GIA, made that the tissue that coincide waited at some anatomical position does not have enough operative spaces to offer the operation of surgical linear Endo-GIA.The dissatisfied place of making us of the firing lock of the surgical linear Endo-GIA of above-mentioned three kinds of styles is: first; Because push button is one-sided outstanding to the nail bin frame, when push button is pulled the trigger, the one-sided active force that applies that surgical doctor only can the linear Endo-GIA of orthopaedic surgical operations; The surgical doctor less to strength; Or to cutting the bigger operative site of resistance that coincide, for example, identical thicker or harder the waiting of cutting coincide and organizes; Or the anastomosis staple at cutting this tissue place that waits to coincide when coincideing last operation, just be difficult to reach the operation purpose that the tissue of waiting to coincide is accurately coincide; Second; Because push button is one-sided outstanding to the nail bin frame; The point of force application of the slide block of the outstanding position of push button in push button and nail bin frame is far away, and therefore, the power that push button acts on slide block forms cutting coincide useful thrust and useless moment of torsion; The frictional force between moment of torsion increase slide block and the nail bin frame and the distortion of slide block, the resistance thereby the cutting of increase firing lock coincide; The 3rd, when push button begins to pull the trigger, or when push button is accomplished percussion, or return when resetting when push button, firing lock is numbness, the also voiceless sound prompting operation technique personnel variation of pulling the trigger process both, thereby possibly cause the firing lock operate miss.Therefore the firing lock of existing surgical linear Endo-GIA also need improve.
Two push buttons of the firing lock of the surgical linear Endo-GIA of this utility model are separately around the pivoted of slide block.When each push button after the pivoted of slide block, push button launches to the outside of nail bin frame.Both can the nail bin frame push button in left side launch to the left side of nail bin frame, push button that also can nail bin frame right side launches to the right side of nail bin frame, two push buttons that can also nail bin frame both sides launch to the left and right sides of nail bin frame respectively.When push button promotion slide block moves forward in the nail bin frame; Slide block promotes push rod and in the nail bin frame, moves forward; Push rod promotes ejector pin again and tiltedly carves with cutter and in the nail bin frame, move forward, and ejector pin is tiltedly carved and promoted each ejector pin piece more successively anastomosis staple is released in nail bin.Compare with existing surgical linear Endo-GIA; The firing lock of the surgical linear Endo-GIA of this utility model reaches both when clamping waits to coincide the operation of organizing; Push button is any side-prominent to the nail bin frame not, do not influence surgical doctor clamp hook is applied active force; Again when push button percussion operation; Surgical doctor can also coincide according to cutting and treat the thickness and the soft or hard of identical tissue; Or whether this tissue place that waits to coincide has anastomosis staple when coincideing last operation according to cutting; Or big or small according to the strength of surgical doctor, select one hand or both hands to apply the position of the push button of active force; Also do not increase the entire length of surgical linear Endo-GIA, do not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.
Two push buttons of the firing lock of the surgical linear Endo-GIA of this utility model have pivot hole and arcuate groove respectively, the unfolded wing in the left and right sides of the oriented nail bin frame of slide block far-end.When each push button after the pivoted of slide block; Push button launches to the outside of nail bin frame; The arcuate groove of push button is inserted on the wing of slide block, and push button makes slide block in the nail bin frame, move forward through the wing that arcuate groove promotes slide block, and slide block promotes push rod again and in the nail bin frame, moves forward; Push rod promotes ejector pin again and tiltedly carves with cutter and in the nail bin frame, move forward, and ejector pin is tiltedly carved and promoted each ejector pin piece more successively anastomosis staple is released in nail bin.Compare with existing surgical linear Endo-GIA; Because the push button of the firing lock of the surgical linear Endo-GIA of this utility model makes slide block in the nail bin frame, move forward through the wing that arcuate groove promotes slide block; Therefore the point of force application of the slide block of the outstanding position of push button in push button and nail bin frame is nearer; Can reduce slide block and the frictional force between the nail bin frame and the distortion of slide block that moment of torsion produces as far as possible, thereby reach the result of use of the identical resistance of cutting that reduces firing lock.
The firing lock of the surgical linear Endo-GIA of this utility model, when push button is in when waiting to pull the trigger state, the elastic projection of slide block springs in the proximal orifice of bottom of nail bin frame, slide block is constrained in the near-end of nail bin frame; When push button is in when accomplishing the percussion state, the elastic projection of slide block springs in the mider hole of bottom of nail bin frame, slide block is constrained in the middle part of nail bin frame; When beginning to promote push button, act on of the constraint of the hole of the bottom of making every effort to overcome clothes nail bin frame on the push button to the elastic projection of slide block, make push button promote slide block and in the nail bin frame, move forward and backward.Therefore; When push button be in when waiting to pull the trigger state or when push button be in when accomplishing the percussion state, maybe when beginning to promote push button; Compare with existing surgical linear Endo-GIA; The firing lock of the surgical linear Endo-GIA of this utility model is through the resistance that changes elastic projection and move and sound, and pulls the trigger the result of use of the variation of process thereby reach firing lock through feel and sound double-reminding operation technique personnel.
The surgeon is when using the surgical linear Endo-GIA of this utility model; Two push buttons of firing lock draw the left and right sides at the nail bin frame respectively in; Both can the nail bin frame push button in left side launch to the left side of nail bin frame; Push button that also can nail bin frame right side launches to the right side of nail bin frame, and two push buttons that can also nail bin frame both sides launch to the left and right sides of nail bin frame respectively.Thereby reach when clamping waits to coincide the operation of tissue, push button is any side-prominent to the nail bin frame not, do not influence surgical doctor clamp hook is applied active force; When push button percussion operation; The resistance of firing lock is less; Surgical doctor can also coincide according to cutting and treat the thickness and the soft or hard of identical tissue; Or whether this tissue place that waits to coincide has anastomosis staple when coincideing last operation according to cutting, 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 force; Also do not increase the entire length of surgical linear Endo-GIA, do not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.When push button be in when waiting to pull the trigger state or when push button be in when accomplishing the percussion state, maybe when beginning to promote push button; The firing lock of the surgical linear Endo-GIA of this utility model is through the resistance that changes elastic projection and move and sound, and pulls the trigger the result of use of the variation of process thereby reach firing lock through feel and sound double-reminding operation technique personnel.
So can find out that the above-mentioned target of stating comprises that those targets that shown by the front explanation have been reached effectively.Described here only is the typical best form of implementation of this utility model application, can do some to said structure and change also spirit and scope without prejudice to this utility model.This utility model does not limit to or is placed restrictions on the detail of being stated in here, and that kind of stating in should qualification as claim to keep affiliated field secondary technology personnel be conspicuous any improvement or remodeling.
