Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to the instruction of disposable rotation cast Endo-GIA
Safety device matches with disposable rotation cast Endo-GIA, is suitable for the operation on digestive tract such as clinical esophagus, stomach, intestines
In end-end, end to side and side-side-to-side anastomosis.
Background technique
Circular-pipe anastomat is a kind of medical instrument being commonly used when carrying out surgical operation to physiological tissues such as alimentary canals.
This kind of stapler mostly uses greatly the inside bookbinding form of axis, and two sections of tissues are containing when coincideing, and portion forms circular anastomosis ring within the organization,
The instrument can enable the body bleeding generated in surgical procedure as content is discharged together, and collective organization is easier after operation
Healing.
Currently, excision of the lesion and suture generally are carried out by stapler for operation on digestive tract, it is existing for controlling
The flexible handle of system excision and suture is fixed with fixed handle position, due to the real-time direction needs of stapler in the course of surgery
It is determined according to the concrete condition of operation, so that it sometimes appear that the position of flexible handle can hinder the operating space of operation
Or the position of flexible handle causes surgical staff to operate uncomfortable situation.
Summary of the invention
The utility model aim is in view of the above shortcomings, to provide a kind of finger of disposable rotation cast Endo-GIA
Show safety device, is matched with disposable rotation cast Endo-GIA, in operation on digestive tract, pass through rotating handle, energy
Enough any angles adjust the position of fixed handle and resist-nailed seat, reduce operating difficulty, and the position of flexible handle is avoided to hinder operation
Operating space.By indicating safety device, cutting anastomotic site can be clearly observed, prevents mistakenly hit from sending out.
The instruction safety device of disposable rotation cast Endo-GIA adopts the following technical solutions to achieve:
The instruction safety device of disposable rotation cast Endo-GIA includes spring leaf, form, indicator, pointer drawing
Hook, adjusting block, guider screw and compressed spring.Indicator lower part is provided with fixed handle mounting hole, is mounted on fixed handle
In indicator mounting post, lower end is provided with pointer drag hook boss, and top is provided with pointer and spring leaf installation base, spring leaf peace
In the indicator mounting post of fixed handle, top is acted against on the spring leaf installation base of indicator, is provided on form
Fixed handle installation base is mounted in the form mounting groove of fixed handle, through transparent window, it can be seen that the pointer of lower section,
Pointer drag hook front end is provided with drag hook, and rear end is provided with screw rod mounting hole, and middle part is provided with insurance plane, and pointer drag hook is sleeved on
On screw rod, it is mounted in the pointer drag hook loose slot of fixed handle, the drag hook of front end hooks on the pointer drag hook boss of indicator,
Compressed spring is sleeved on screw rod, and front end abuts against pointer drag hook, and rear end acts against on adjusting nut, and adjusting block is U-shaped, and centre is set
It is equipped with kidney slot, adjusting block is mounted on screw rod by guider screw, and guider screw is fixedly mounted on guider screw installation screw thread
In hole.It is acted against on adjusting block on the left of pointer drag hook, guider screw is movable in the guider screw loose slot of fixed handle.
Fixed handle front end is provided with rotary switch protrusion, and front inner is provided with rotating handle installation protrusion, rotates hand
Handle installation protrusion right side is provided with torsional spring backing pin mounting hole, and downside is provided with flexible handle loose slot, is provided with work on the upside of lower part
Fixed handle pin mounting hole and indicator mounting post, top are provided with form mounting groove, and pointer drag hook activity is provided on the downside of rear portion
Slot, rear portion middle part are provided with guider screw loose slot, and fixed handle rear end is provided with adjusting nut mounting groove.The fixed handle
It is made of left fixed handle and right fixed handle two parts.
The instruction safety device of disposable rotation cast Endo-GIA, it is mating with disposable rotation cast Endo-GIA
It uses, disposable to rotate 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.
The instruction safety device of disposable rotation cast Endo-GIA, it is mating with disposable rotation cast Endo-GIA
It uses, disposable to rotate 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.
