Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments, method or conversion functionally are all included in protection scope of the present invention.
Expression position described in the present invention and the word in direction are all using exercises on apparatus author as reference, and be near-end near one end of operator, the one end away from operator is far-end.
In embodiments of the present invention, with chamber mirror surgical incision anastomat for example does concrete explaination to Medical stapler of the present invention, but it should be noted that skill spirit involved in following embodiment can use on the anastomat of other form with being replaced.
As shown in Figure 1, in an embodiment of the present invention, the volution 20 that described Medical stapler comprises instrument body 10, connects with described instrument body 10, and the percussion handle 30 of pivotally connected described instrument body 10.
As shown in Figures 1 and 2, the far-end of described instrument body 10 is also provided with nail bin groupware 40, and described nail bin groupware 40 comprises nail anvil 401, nail bin 403, nail bin frame 407 and I-shaped cutter 409.
Described nail bin 403 is positioned at described nail bin frame 407.
In the present embodiment, as shown in Figure 2, when described Medical stapler/nail bin groupware is in original state, the nail anvil tail of the near-end of described nail anvil is subject to External Force Acting, to keep described nail anvil 401 and nail bin 403 in opening shape, described I-shaped cutter 409 is positioned at the near-end of described nail bin groupware.
As shown in Figure 3, under the driving of described I-shaped cutter 409, when described Medical stapler/nail bin groupware is in closure state, described nail anvil 401 and nail bin 403 close, and can clamp therebetween and treat physiological tissue.For original state, described I-shaped cutter 409 moves certain distance to the far-end of described Medical stapler/nail bin groupware, but is still positioned at the near-end of described nail bin groupware in general.
When described Medical stapler/nail bin groupware is in cock, described nail anvil 401 and nail bin 403 still remain closed, described I-shaped cutter 409 is distally moved by the near-end of described nail bin groupware, the physiological tissue of cutting clamping, and it is mobile to be subject to spacing stopping at the far-end of described nail bin groupware.
As shown in Figure 2 and Figure 3, in an embodiment of the present invention, described nail anvil 401 comprises nail anvil body 4011, is arranged at the nail anvil tail 4013 of described nail anvil body 4011 near-end.
Described nail anvil body 4011 comprises nail anvil face 40111, and resistance surface 40113 that is opposing with nail anvil face 40111 and that can coordinate with I-shaped cutter 409, and described I-shaped cutter 409 can drive described resistance surface 40113, and described nail anvil 401 is closed with described nail bin 403.
Wherein, the near-end of described resistance surface 40113 or the near-end of close described resistance surface 40113 are provided with a projection 40115, and described protruding 40115 are greater than the vertical dimension in described other parts of resistance surface 40113 and described nail anvil face 40111 with the vertical dimension in described nail anvil face 40111.Be understandable that, the vertical dimension in the described summit of protruding 40115 and described nail anvil face 40111 is described resistance surface 40113 point maximum with the vertical dimension in described nail anvil face 40111.
Further, described protruding 40115 is a curved flanges.Described curved flanges is arranged near the near-end of described resistance surface, and the resistance surface 40113 of described curved flanges and its near-end is set to smooth excessiveness.Although be namely provided with certain gradient between described curved flanges and resistance surface 40113, but do not formed stepped, but by circular sliding slopes excessively (airflow design), during to ensure that described I-shaped cutter 409 drives described nail anvil 401 to close with described nail bin 403, and the process of sliding from the near-end of described resistance surface 40113 to described curved flanges keeps relatively level and smooth.Certainly, the resistance surface 40113 of described curved flanges and its far-end also can be set to smooth excessiveness.
Wherein, described I-shaped cutter 409 comprises cutter hub 4091, is arranged at first auxiliary section 4093 and second auxiliary section 4095 at described cutter hub about 4091 two ends respectively.
Described first auxiliary section 4093 can coordinate described resistance surface 40113, and described resistance surface is slided.Described second auxiliary section 4095 can coordinate described nail bin frame 407, and described nail bin frame 407 slides.So, described I-shaped cutter distally can be moved by the near-end of described nail anvil 401 and described nail bin 403, certainly, also proximally can move from the far-end of described nail anvil 401 and described nail bin 403.
Driven the resistance surface 40113 of described nail anvil 401 by described first auxiliary section 4093, the far-end of described nail anvil 401 can be made to draw close to described nail bin 403, finally arrive closure state to make nail anvil 401 and nail bin 403.
Further, described nail anvil 401 also comprises a nail anvil lid 4015, and described nail anvil lid 4015 is arranged at the side of described resistance surface 40113, and the slideway 4017 coordinating formation one to allow the first auxiliary section 4093 of described I-shaped cutter 409 to pass through with described resistance surface 40113.
Further, described protruding 40115 is that this plastic cement is elastomeric material by formed at the near-end plastic-injection of described resistance surface 40113.When described resistance surface 40113 does not arrange described protruding 40115, after Jia Bi physiological tissue, described nail anvil 401 is parallel with nail bin 403, or becomes one towards the described angle of apparatus far-end and the opening direction of angle towards the far-end of described apparatus.Due to the described setting of protruding 40115, when described I-shaped cutter 409 acts on described protruding 40115, give nail anvil 401 1 towards the active force in nail bin direction by described resistance surface 40113, the angle towards described apparatus far-end ordering about original parastate or formation between described nail anvil 401 and nail bin 403 changes, form one towards the angle of described apparatus near-end, or the original angle towards apparatus far-end is diminished.Namely, when described nail anvil 401 and described nail bin 403 arrive closure state, described I-shaped cutter and the described conflict of protruding 40115 cooperation can ensure when closed, clamp the tissue between described nail anvil 401 and described nail bin 403 more tightly.
Be appreciated that in the present embodiment, arrive closure state when described I-shaped cutter 409 acts on described Medical stapler/nail bin groupware, between described nail anvil face 40111 and described nail bin face 4031, coordinate formation one towards the angle of described nail bin groupware near-end.Further, described angle is acute angle.So, when described nail bin groupware arrives closure state, between described nail anvil 401 and described nail bin 403, clamped organizing not easily is slided, and improves the degree of safety of operation.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
