The haemorrhoid anastomat for the operations comprises a nail abutting base, an annular cutter, a nail bin sleeve, a nail pushing sheet, a fixing handle, a safety block, a movable handle and a nail bin. The haemorrhoid anastomat for the operations is characterized in that symmetrical positioning ribs are fixed on a connecting shaft of the nail abutting base, the symmetrical positioning ribs are symmetrically distributed on the upper face and the lower face of the connecting shaft; symmetrical positioning grooves are formed in the nail bin sleeve, the positioning grooves are formed in corresponding reinforcing ribs, and the positioning grooves are communicated with a center hole of the nail bin sleeve; and the symmetrical positioning ribs on the nail bin base are matched with the symmetrical positioning grooves on the nail bin sleeve. The haemorrhoid anastomat for the operations is simple in structure. An osculating assembly of the haemorrhoid anastomat for the operations and the nail abutting base are concentric, and using is more stable. The symmetrical positioning grooves of the nail bin sleeve are formed in the symmetrical reinforcing ribs, the symmetrical positioning ribs are designed on the connecting shaft of the nail abutting base, and concentricity and stability are guaranteed. Titanium nails are good in forming and uniform in forming heights.
Description
Technical field
The present invention relates to a kind of anastomat, a kind of operation hemorrhoid anastomat particularly, it mainly is applicable to belong to medical apparatus and instruments in the piles operation.
Background technology
In prior art, although the operation of hemorrhoid can be by the disposable mechanical anastomosis of completing the pathological tissues joint-cutting of anastomat.But find by inquiry, the past inclination on one side of nail supporting base or nail supporting base and anastomosis cut component decentraction during the percussion of hemorrhoid anastomat, asymmetric inconsistent with forming height thereby generation titanium nail is shaped, this might affect match result, and can cause Anastomotic bleeding.
find by technical Analysis, the inner core of existing hemorrhoid anastomat nail storehouse sleeve all only has plane of orientation and a locating slot at 45 ° with reinforcement, the nail storehouse sleeve inner core is due to the unsymmetry of structure like this, can produce internal strain in the course of processing, cause the inner core center unstable, again due to locating slot not on reinforcement, so insufficient strength, might be due to self resistance to deformation insufficient strength when anastomat percussion nail is shaped, the hemorrhoid anastomat is unstable and insufficient strength due to the center, support nail toward tilting when percussion on one side, thereby producing the titanium nail is shaped asymmetric inconsistent with forming height.
Find by technical Analysis, the nail supporting base coupling spindle adds a plane of orientation and positioning bar on pole, because bar has interior gravitation, if surface of fracture is asymmetric, bar will be out of shape, so just might cause nail supporting base and anastomosis cut component decentraction, be shaped asymmetric inconsistent with forming height thereby produce the titanium nail.
China Patent No. 2004200240651 discloses the utility model patent that a kind of name is called " a kind of improved anastomosis cut component ", and it is to be provided with 3-8 hook wire casing on nail storehouse sleeve at the needle chamber cover, shortens operating time by increasing the hook wire casing.But the structural design that this needle chamber cover is nail storehouse sleeve is still reasonable not, and it does not overcome defects of the prior art.
China Patent No. 2009201622266 discloses the utility model patent that a kind of name is called " surgical operation anastomosis ring applicator ", its purpose be for solve nail storehouse sleeve and adapter sleeve be axially accurately locating of sleeve pipe and be convenient to the assembling, and coordinate to reach above goal of the invention by the mortise on nail storehouse sleeve with draw pin on adapter sleeve, although this technical scheme has partly solved the axial location problem of nail storehouse sleeve, but due to its nail supporting base and nail storehouse sleeve and structural design still reasonable not, it does not still overcome defects of the prior art.
China Patent No. 012377597 discloses the utility model patent that a kind of name is called " a kind of flexible digestive tract stapler ", but its center-pole is designed to the form of bending, with convenient operation, reduces damage; Lever parts and nail seat parts adopt hose connection, thus the crooked radian of scalable flexible pipe.But the center-pole of this anastomat all connects with flexible pipe, stability and the rigidity of anastomat have been reduced, scale value and the actual variable thickness of coincideing are caused, thereby cause coincideing not exclusively, cause Anastomotic bleeding, also might cause excessive compression anastomosis tissue, cause organizing blood supply insufficiency, cause necrosis; Simultaneously, it does not overcome defects of the prior art yet.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide that a kind of structural design is more reasonable, the better operation hemorrhoid anastomat of concentricity and stability.
the present invention addresses the above problem the technical scheme that adopts: this operation comprises flap with the hemorrhoid anastomat, nail supporting base, over cap, endless knife, nail storehouse sleeve, pushing slice of nail, sleeve pipe, screw mandrel, fixed handle, safety block, flexible handle, straight push rod and nail bin, nail supporting base, endless knife, nail storehouse sleeve, pushing slice of nail is on same axis, endless knife, nail storehouse sleeve, pushing slice of nail and nail bin form anastomosis cut component, nail storehouse sleeve and nail bin are fixed, nail supporting base coordinates with nail storehouse sleeve, it is characterized in that: the positioning bar that is fixed with a symmetry on the coupling spindle of described nail supporting base, this symmetrical positioning bar is symmetrically distributed on the upper and lower surfaces of coupling spindle, have the locating slot of a symmetry on described nail storehouse sleeve, this locating slot is opened on the reinforcement corresponding with it, and locating slot communicates with the center of nail storehouse sleeve, on described nail supporting base on symmetrical positioning bar and nail storehouse sleeve the locating slot of symmetry match.Make thus concentricity of the present invention and stability better, make the shaping of titanium nail more intact, forming height is more consistent.
The present invention is evenly equipped with four kidney slots of symmetry in twos on the outer surface of described nail storehouse sleeve, wherein two kidney slots are distributed on the horizontal center line of nail storehouse sleeve symmetrically.
The present invention compared with prior art, have the following advantages and effect: structural design is more reasonable, anastomosis cut component of the present invention and nail supporting base are more concentric, use more stable; The symmetrical locating slot design of nail storehouse sleeve is designed with symmetrical positioning bar on the coupling spindle of nail supporting base on symmetrical reinforcement, guaranteed concentricity and stability, the titanium nail is shaped more intact, and forming height is more consistent.
