Disposable rotation cast Endo-GIA working principle:
Generally when carrying out operation on digestive tract, rotating adjusting nut counterclockwise first, in screw rod rear end, adjusting nut is matched
Under the action of closing screw thread, promotion is vertically connected with bar, is vertically connected with piece, guiding axis, circlip pipe, Clip Reed, resist-nailed seat, will support nail
Seat circlip tube portion screws out, and pulls up the resist-nailed seat circlip pipe assembled, will need to cut identical tissue and accomplishes fluently pocket, will support nail
Seat circlip pipe clamp be attached on guiding axis, doctor can up push rotary switch at this time, make the rotary switch protrusion of fixed handle from
Abjection in the rotation card slot of rotating handle, rotatable rotating handle, drives nail bin, nail storehouse sleeve by curved aluminum pipe, curved push rod at this time,
Resist-nailed seat rotation, is adjusted to suitable surgery location, unclamps rotary switch, under the action of rotary switch spring, fixed handle
On rotary switch protrusion continue to be installed on rotation card slot.Adjusting nut, observation window are rotated clockwise again, if pointer does not have
Flexible handle is accidentally pressed to firing position, at this point, the insurance boss of flexible handle acts against the insurance of pointer drag hook
It in plane, can not fire, continue rotating adjusting nut, until pointer indicates firing position, at this time the insurance boss of flexible handle
The hollow place in left side of insurance plane in pointer drag hook, presses flexible handle, pushes straight push rod, curved push rod, pushing slice of nail, annular
Knife completes cutting and coincide, and under the action of firing spring, straight push rod, curved push rod, pushing slice of nail, endless knife is driven to reset.
Disposable rotation cast Endo-GIA advantage:
Disposable rotation cast Endo-GIA, design are rationally, compact-sized.In operation on digestive tract, by rotating hand
Handle is capable of the position of any angle adjusting fixed handle and resist-nailed seat, reduces operating difficulty, the position of flexible handle is avoided to hinder
The operating space of operation.By indicating safety device, cutting anastomotic site can be clearly observed, turn adjusting nut, indicator is not
To firing position, flexible handle is accidentally pressed at this time, then cannot be fired, if continuing turn adjusting nut, indicator instruction is hit
Position is sent out, presses flexible handle at this time, percussion can be completed, is reduced in operation, bring operative failure due to maloperation, hand is improved
Art success rate.Big form design, the observation instruction pin position that can be more clear, it is difficult to reduce the observation of doctor in the course of surgery
Degree.Sharp cutter can once cut off tissue at the time of surgery, complete cutting suture, mitigate the pain of sufferer.Flexible handle
Encapsulated processing technology is used with fixed handle, frosted sense of touch can play anti-skidding effect, both wings tune in the course of surgery
Nut design is saved, when rotated more easily.
Disposable rotation cast Endo-GIA passes through rotating handle, screw rod, up and down since resist-nailed seat regulating device is arranged
Bar, upper connection sheet, lower connection sheet, guiding axis are connected, can conveniently adjust position between resist-nailed seat and nail bin, endless knife, side
Just surgical procedure.
Rationally, compact-sized, driving is stablized for the push jack driving device structure design of disposable rotation cast Endo-GIA,
Moment is big, and intensity is high, in operation on digestive tract, rotating adjusting nut, and until pointer indicates firing position, flexible handle at this time
Insurance boss is in the hollow place in left side of the insurance plane of pointer drag hook, presses flexible handle, pushes straight push rod, curved push rod, pushes away
Follow closely piece, endless knife, it is disposable to complete cutting, coincide, under the action of firing spring, drive straight push rod, curved push rod, pushing slice of nail,
Endless knife resets, and surgical procedure is convenient, it is ensured that successful surgery.
The fixed device design of the nail bin of disposable rotation cast Endo-GIA is rationally, compact-sized, since nail bin is installed
In nail storehouse sleeve front end, raised phase secure fit is installed by the nail bin of nail storehouse sleeve installation groove and nail storehouse sleeve, curved aluminum pipe front end is logical
It crosses nail storehouse sleeve installation male cooperation to be mounted in the curved aluminum pipe mounting groove of nail storehouse sleeve, retainer before outside is set with, curved aluminum pipe rear end is set
It is equipped with rotating handle mounting hole, is fitted in the curved aluminum pipe installation protrusion of rotating handle, retainer after the suit of outside, nail bin,
Curved aluminum pipe, rotating handle fixing-stable are reliable, easy to install and use.
