Abstract
The invention discloses the devices for restoring initial position after a kind of percussion for minimally invasive hysteroscope Endo-GIA, comprising: 1 constant force spring is fixedly connected with driving rack；2 process scale on constant force spring, observe drive position information by transparent amplification form.Constant force spring described in claim is fixedly connected with driving rack, driving rack can be made rapidly to reset, and since constant force spring stress is relatively uniform, avoids the plastic components intense impact in reseting procedure to instrument.In addition scale is processed on constant force spring, drive position information is observed by transparent amplification form, simplifies the structure that drive position is shown, display is accurate.The quality for improving product is stablized, and the specific requirements of appliance function are sufficiently met.
Description
Technical field
The invention belongs to minimally invasive medical instrument fields, and in particular to a kind of minimally invasive hysteroscope Endo-GIA recovery initial position
Device, minimally invasive hysteroscope Endo-GIA be in Minimally Invasive Surgery excision, a kind of cross-section and anastomosed tissue instrument.
Background technique
Hysteroscope Endo-GIA is widely used in needle holder being applied to surgery Minimally, instead of the hand cut and suture of traditional operation,
Now it is summarized as three categories:
A, percussion+spanner is pulled back reset three times, and most widely used at present, structure is simple, and Technical comparing is mature and stable.The disadvantage is that
Its component cost is relatively high.
B, percussion+cylindrical spring pulls back reset as a kind of upper trend of instrument progress and has had phase at present three times
When use lead to reset of pulling back since cylindrical spring stress is related with the deflection of spring in such instrument use process
When generate moment stress it is excessive, have instrument plastic structural part by the risk of impact fracture.
C, electronic percussion+electronic reset, battery+motor driven that the percussion of such instrument is carried with reset by instrument, by
More expensive in price, market penetration rate is lower.
We give more sustained attention, collect the clinical information of various such instruments, the characteristics of for b class instrument, determine to instrument
Structure of pulling back improve, avoid risk of the plastic structural part by impact fracture.
Summary of the invention
The technical problem to be solved in the invention is mainly to improve resetting structure of pulling back, and avoids instrument plastic structural part quilt
The risk of impact fracture.
The present invention is fixedly connected using constant force spring (also known as wind spring) with driving rack, during instrument percussion, transmission
Constant force spring accumulation of energy is driven while remaining moving component of rack drives, after the completion of percussion, pushing stopping mechanism aside makes driving cog
Radial motion is without hindrance, provides continual and steady pulling force using constant force spring release accumulation of energy, dilatory driving rack drives remaining
Movement mechanism return initial position.
In addition it is attached to a function, is moved synchronously using constant force spring and driving rack, is processed on constant force spring steel band
Scale for showing percussion/reply position, while utilizing optics convex lens principle, has enlarging function with transparent material production
Display window, drive display structure for substituting original gear.
It is had the following advantages compared with using structure on existing product:
A, original structure is combined using cylindrical spring, in order to keep the stationary performance of pulling force, can only use several spring assemblies
Get up to use, structure is complicated, and pulling force is not stable enough, there is example of the plastic structural part by impact fracture in use.This
There is constant force spring used in invention accumulation of energy release to stablize, and dilatory driving rack strength is steady, it is possible to prevente effectively from product
Plastic structural part is structurally reasonable reliable by impact fracture.
B, original position is shown is driven using gear, has the features such as structure is complicated, and process and assemble process is more.The present invention
Position used is shown, processes scale on constant force spring steel band, is shown with the convex lens with enlarging function, has assembly effect
The advantages that rate is high, structurally reasonable reliable, clear scales, generous tailored appearance.
Detailed description of the invention
Fig. 1: the product shape without component.
Fig. 2: removal casing-upper half.
Fig. 3: the octuple enlarged drawing in two part of figure.
Fig. 4: the structure chart of constant force spring and driving rack；Part sequence number is corresponding: driving rack (part 1), constant force spring with
Driving rack fixed pin (part 2), constant force spring briquetting (part 3), constant force spring (part 4), constant force spring and shell fixed pin (part
5).
Specific embodiment
Further details of explanation is made to the present invention below in conjunction with attached drawing.
Referring to shown in attached drawing, restore the device of initial position after a kind of percussion for minimally invasive hysteroscope Endo-GIA.
It include: that 1 constant force spring is fixedly connected with driving rack；Scale is processed on 2 constant force springs, passes through transparent amplification form
Observe drive position information.
During instrument percussion, driving rack drives constant force spring accumulation of energy while driving remaining moving component, is hitting
After the completion of hair, pushing stopping mechanism aside keeps driving rack radial motion without hindrance, is continued using constant force spring release accumulation of energy offer steady
Fixed pulling force, dilatory driving rack drive remaining movement mechanism to return to initial position.
Moved synchronously using constant force spring and driving rack, process scale on constant force spring steel band, for show percussion/
Position is replied, while utilizing optics convex lens principle, makes display window with transparent material.
When use: instrument percussion is completed, and automatically into initial position is restored, is resetted rapidly.In percussion/reseting procedure,
The running position of instrument can be paid close attention to by transparent amplification form.
The device of the invention has more optimized structure, rationally reliable, assembly efficiency height, position compared with original structure
Show the advantages that clear.
The technical concepts and features of structure described above only to illustrate the invention, are a kind of preferred technical concept, mesh
Be that related practitioner cans understand the content of the present invention and implement it accordingly, protection model of the invention can not be limited with this
It encloses.Equivalent transformation or modification made by all Spirit Essences according to the present invention, should be covered by the protection scope of the present invention.
