Description
Technical field
This utility model relates to surgical instruments, especially a kind of surgical operation anastomat, in particular it relates to the surgical instruments improved, especially its controller, it is possible to one-handed performance apparatus realizes specific function.
Background technology
The action principle of surgical stapling, is closed by two corresponding jaws (being commonly referred to nail-anvil assembly and nail bin groupware) to clamp tissue, is then followed closely by the metal suture in anastomat nail storehouse and releases molding, by tissue apposition together. In some anastomat, it is also equipped with cutter, for being cut off by the tissue sewed up.
The anastomat with above-mentioned functions includes an executor, intermediate connector and controller. Executor is made up of nail-anvil assembly, nail bin groupware and driving assembly. Nail-anvil assembly comprises a nail forming surface, and nail forming surface comprises many nail-arranging slots, and nail groove is for the molding of metal suture nail. Nail bin groupware generally comprises nail bin, suturing nail, ejector pin block and ejector pin slide block and staple cartridge tray, and the upper surface of nail bin is tissue contact surface, and nail bin is arranged in staple cartridge tray. Together with nail-anvil assembly is movably attached to the near-end of nail bin groupware at near-end, it is possible to change between open configuration and closed mode. Assembly is driven to be connected with drive mechanism, for the action of firing trigger is converted to the closedown of executor, percussion and expansion action. Generally, nail-anvil assembly and staple cartridge tray also respectively comprise a cannelure, and above-mentioned cannelure is used for holding driving assembly and passes through. When driving assembly by above-mentioned cannelure to the distal movement of executor, nail-anvil assembly and nail bin groupware can be ordered about and be converted to close off state from open configuration, and order about ejector pin slide block and ejector pin block ejects suturing nail molding in the nail groove of the nail forming surface of nail-anvil assembly. Generally, driving assembly also to include cutter, for after tissue is sewn stapling conjunction, between multiple rows of staple line, cutting is organized.Controller, for Non-follow control operation apparatus, has generally comprised a fixed handle, the firing trigger that is dynamically connected relative to fixed handle, and one group is transmitted the firing trigger action drive mechanism to executor, a hand-reset assembly. When the nail bin groupware of executor is in closure state with nail-anvil assembly, operates manual reset assembly and can order about nail bin groupware and nail-anvil assembly recovery open configuration. Intermediate connector is movably connected with the far-end of controller, and links together with the near-end of executor, and intermediate connector constitutes an interface channel, for realizing the action of firing trigger is passed to executor.
Such as, american documentation literature US2014/0001233A1 discloses a kind of anastomat, this anastomat is operated by firing trigger can make the nail-anvil assembly of executor and nail bin groupware be converted to close off state to perform the action such as pressing, percussion from open configuration, need during reset to be pulled back to hand-reset assembly with another hands, order about nail bin groupware and recover open configuration with nail-anvil assembly. This technical scheme does not have firing safety mechanism, it is impossible to effectively prevent mistakenly hit from sending out, and organize percussion to be the coherent process that a Continued depression operates firing trigger from pressing, it is impossible to make doctor perceive control clearly and perform pressing and firing action respectively.
Again such as, a kind of stiching instrument disclosed in Chinese patent literature CN202950702U, although this stiching instrument has possessed percussion safety device, but, the operation button controlling this percussion safety device is positioned at the side of stiching instrument, cause the hypertelorism between this operation button and percussion spanner, make it difficult to one-handed performance, even so, even if assuming that the finger of doctor is longer, then doctor need nonetheless remain for being operated respectively the operation button of firing trigger and percussion safety device by forefinger and thumb, in the process, owing to thumb general and other four refers to be positioned at the not homonymy of stiching instrument handle, therefore the lax of thumb is easily caused gripping stiching instrument shakiness. and this stiching instrument does not have automatic reset mechanism, doctor is after operation performs one step press action, need hand-reset structure to be pulled back the initial position of near-end with another hands, just can make to order about nail bin groupware and recover open configuration with nail-anvil assembly, therefore, it is operated it is true that this stiching instrument need nonetheless remain for two handss when tissue is carried out pressing by needs repeatedly, and one-handed performance can not be realized.
Again such as, the EndoGIAUniversal Endo-GIA that TycoHealthcare company of the U.S. (renames as Covidien) afterwards, and the Echelon Endo-GIA of EthiconEndo-Surgery company of the U.S. is the representational product realizing above-mentioned functions. The said goods is sold for many years, is also proved have good clinical application effect by market. But, the design of these apparatuses still there is a need to perfect place, and such as apparatus is in operation, and some operation needs both hands cooperation just can complete, and is unfavorable for that operative doctor operates apparatus in operation process.
Such as, in US Patent No. 5,865,361, function and the design of EndoGIAUniversal Endo-GIA (hereinafter referred to as EndoGIA anastomat) are described by TycoHealthcare. When firing the firing trigger of EndoGIA anastomat, the nail-anvil assembly of anastomat and nail bin groupware will be changed into closed mode from open configuration, clamp destination organization. In operation, need to adjust the position that clamping is organized if doctor thinks, then doctor needs to be pulled back to hand-reset assembly with another hands, order about nail bin groupware and recover open configuration with nail-anvil assembly. In actual operation, the destination organization of anastomat includes the tissues such as stomach, lung, large intestine, and wherein, these tissues of harmonization of the stomach large intestine are generally relatively thick, and anatomical lumens has abundant wrinkle, surface to be likely to also have the fatty tissue not being kept completely separate; And in lung tissue, have substantial amounts of alveolar, therefore, the executor of anastomat is when first time closes and clamps above-mentioned tissue, and due to reasons such as the thickness of tissue, wrinkle, fatty tissue or in-house bubbles, tissue is generally difficult to be compressed into desirable uniform thickness. By repeatedly at same position clamping tissue, it is possible to effectively eliminate the tissue compression non-uniform phenomenon that above-mentioned factor causes, making anastomat when ordering about titanium nail anastomosed tissue and cutting tissue subsequently, titanium nail forming height is uniform, and match result is good, and tissue incisxal edge is smooth. Realizing repeatedly clamping tissue at same tissue site, doctor needs to unclamp the apparatus that another hands grips, and repeatedly with the hands operates firing trigger and the hand-reset trigger of EndoGIA anastomat.Additionally, the executor of EndoGIA anastomat is after correct clamping tissue, doctor is before determining identical and cutting tissue, firstly the need of pressing the percussion safety button of anastomat with another Hand supplementary to open percussion safety device, then could again operate firing trigger and perform subsequent action, this makes troubles to instrumentation, brings additional risk to operation. In micro-wound surgical operation, doctor's two handss sometimes operate different apparatuses respectively, if a certain apparatus needs two handss to operate simultaneously, doctor needs first to unclamp another apparatus of gripping. In micro-wound surgical operation, the apparatus not controlled by doctor is arranged in external controller and likely shifts, shifting it is possible to cause a large amount of uncontrolled displacement of the executor of apparatus far-end on a small quantity of apparatus controller because of art touching unexpectedly; Because of the tissue in executor and the surgical target district of apparatus far-end and organ very close to, the uncontrolled displacement of executor likely damages neighbouring tissue and organ. Not operating apparatus room temporarily, this apparatus can be extracted out external by some doctor, to avoid risk; In some cases, apparatus can be taken over to hold up by other doctor temporarily and hold; Sometimes, doctor simply unclamps apparatus, and is pressed against by the far-end of apparatus in the gap of some tissue or tissue, these movements or can extend operating time, or there is damage organizes the risk with organ.
If doctor's one-handed performance anastomat just can realize clamping repeatedly and organize the function at same position, doctor will be very beneficial for and implement operation, and promote the thickness evenness of held destination organization, and then improve identical and cutting effect. If under the premise of not sacrificing security, doctor can open firing safety mechanism by one-handed performance, also will reduce the risk in operation process, shortens operating time.
