Description
Technical field
Surgical instruments of the present invention, particularly relates to a kind of surgical operation anastomat; Particularly, relate to by a direction control mechanism, when making the same firing trigger of percussion, the executor of surgical instruments performs the control device of different actions.
Background technology
The action principle of surgical stapling, is closed with grasping tissue by two corresponding jaws, then the peg in anastomat nail storehouse is released molding, by tissue apposition together.In some anastomat, cutter are also housed, open for the tissue sewed up is cut off.
The anastomat with above-mentioned functions includes executor, intermediate connector and a controller.Executor is made up of nail-anvil assembly, nail bin groupware and driven unit.Nail-anvil assembly comprises a nail forming surface, and nail forming surface comprises many nail-arranging slots.Nail bin groupware generally comprises nail bin, suturing nail, ejector pin block and ejector pin slide block and nail bin seat, and the upper surface of nail bin is tissue contact surface, and nail bin is arranged in nail bin seat.Nail-anvil assembly movably links together at the near-end of the nail bin seat of near-end and nail bin groupware, and can change between open configuration and closed condition.Driven unit is connected with drive mechanism, for the action of firing trigger being converted to the closedown of executor, percussion and expansion action.Generally, nail-anvil assembly and nail bin seat also comprise a cannelure, and above-mentioned cannelure passes through for holding driven unit.When driven unit by above-mentioned cannelure to the distal movement of executor time, can nail-anvil assembly be ordered about and nail bin groupware is converted to closed condition from open configuration, and order about ejector pin slide block and ejector pin block ejects nail and molding in the nail forming tank of the nail forming surface of nail-anvil assembly.Generally, driven unit also comprises cutter, for be sewn nail stitching at tissue after, cuts and organizes between many nails line.Controller is used for Non-follow control operating apparatus, has generally comprised a fixed handle, the firing trigger that is dynamically connected relative to fixed handle, and one group is transmitted the drive mechanism of firing trigger action to executor.Intermediate connector is movably connected with the far-end of controller, and links together with the near-end of executor, and intermediate connector forms an interface channel, for realizing, the action of firing trigger is passed to executor.The EndoGIAUniversal Endo-GIA of Covidien company of the U.S. is the representational product realizing above-mentioned functions, US Patent No. 5,762, and 256 are described this product correlation technique.The said goods is sold for many years, is also proved to have good clinical application effect by market.But the design of this apparatus still has needs perfect place, the complexity of such as structure, the convenience of operation and reduction production cost.
Such as, at patent US5,762, in 256, after anastomat completes firing action, need driven unit to be retracted into initial position, in the technical scheme of patent and accompanying drawing, describe two kinds of backing mechanisms, be the automatic rollback mechanism based on energy-storaging spring, a kind of is backing mechanism by manually retracted trigger.
Automatic rollback mechanism based on energy-storaging spring installs in the controller, comprise that an one end is connected with drive mechanism, the other end be fixedly mounted on energy-storaging spring on fixed handle, one prevent the unidirectional locking parts of drive mechanism rollback, switch block and a unidirectional locking reset components opening locking component.Close executor at operation firing trigger drive transmission device, eject suturing nail and in the process of molding, along with the movement of drive mechanism, drive energy-storaging spring distortion and accumulation of energy, produce power drive mechanism being retracted original position.Unidirectional locking parts and drive mechanism can be dynamically connected, and stop drive mechanism to be drawn back.After the operation that anastomat completes cut out and suturing nail molding, console switch parts open locking component, and drive disk assembly just retreats to home position next time in the pulling force effect of energy-storaging spring.After drive disk assembly returns home position, reset components makes unidirectional locking parts also recover home position, makes whole anastomat can pull the trigger another replaceable nail kit or replaceable nail bin.The deficiency of this technical scheme is present in two aspects: one, when energy-storaging spring coefficient of elasticity is not high enough, anastomat is at cut out, percussion suturing nail after molding, tissue and the resistance of apparatus to drive disk assembly and driven unit rollback too high time, the elastic force of energy-storaging spring savings likely deficiency allows drive disk assembly set back completely, and this is a very large risk to the safety of patient in operation; They are two years old, if energy-storaging spring coefficient of elasticity is too high, then spring is in closedown and percussion process, very large percussion resistance is produced because of pressurized accumulation of energy, in the occasion of some thick organizations, when closing and pull the trigger, the power of operation required for firing trigger is natively very large, and the resistance of the extra energy-storaging spring increased will make a part of surgeon very difficult when percussion, can increase the risk of operation equally.
By manually retracted trigger backing mechanism can longitudinally linear slide installation in the controller, and on the left and right shell of controller, have the sliding-rail groove of one group of symmetry.This backing mechanism at least comprises two rollback triggers, a coupling control assembly and a coupling and controls reset components.Movable the coordinating with percussion tooth bar of rollback trigger, and there is stroke limit with percussion tooth bar.Rollback trigger is controlled reset components and is dynamically linked together by elastomeric element with being coupled, and the percussion direction of deflection percussion tooth bar.Rollback trigger movably links together with the control assembly that is coupled, and coupling control assembly is along with the motion of rollback trigger, and control percussion is pulled out tooth and is in couple state or non-coupled state with percussion tooth bar.In anastomat closing process, or in percussion process, or after having pulled the trigger, when operator wants to exit closed condition or cock, he needs a fixed handle holding controller, another holds two rollback triggers, and draw in the opposite direction to percussion side, rollback trigger is in the stroke of rollback, first the motion of coupling control assembly is driven, make the percussion of firing trigger pull out tooth and be in non-coupled state with percussion tooth bar, then rollback trigger reaches the stroke limit position in percussion tooth bar, and drive percussion tooth bar and rollback trigger together rollback.The deficiency of this technical scheme is present in: the action need operator of backing mechanism uses bimanualness simultaneously, makes operator loosen control to other operating theater instruments; Meanwhile, the operation of both hands makes the executor of anastomat far-end easily produce to rock more greatly, causes being produced displacement by the tissue that clamps or organ and damaging.In the anastomosis procedures of some thick tissue, because the wall thickness of organ is very thick, executor is after tissue is closed in clamping, organize and very large reverse elastic force is produced to nail-anvil assembly and nail bin groupware, in most of the cases can cause nail-anvil assembly or the even plastic deformation of nail bin groupware generation elasticity, the driven unit of executor is in back off procedure, not only need the frictional resistance overcoming driven unit and increase between nail-anvil assembly and nail bin groupware, also to overcome the large drag forces of the plastic deformation of nail-anvil assembly and nail bin groupware, this can increase in operation rollback trigger process further, the amplitude that executor's far-end rocks and to tissue or organ pull power, increase tissue or organ injury risk.
