Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of pre- identical pressure magnetic inductive tube type anastomat.
Background technique
The stitching unstrument coincideing for the various cavities of human body is known as tube type anastomat, can enter and leave in tissue, shape
At the multiple rows of interlaced staple being collectively aligned, at the same with endless knife will its inside tissue cut off, can with progress it is quickly simple
Just the suture of luminal organs.
Traditional tube type anastomat is in the operating process used, by the spacing of resist-nailed seat and nail bin to determine whether group
It knits oneself to be adequately compressed or correctly coincide, therefore, it is necessary to the spacing to resist-nailed seat and nail bin to be indicated so as to doctor's progress
Judgement.However, working as doctor since the indicator to be observed of doctor is located at in the transparent indication window of firing handle opposite side
Since operation technique or operation require, indication window is not towards doctor's sight side when doctor operates instrument；Doctor is in order to observe
Body whether rotate to can fire zone (green area), and be adjusted to can fire zone, according to tissue thickness in green area
When being finely adjusted to instruction pin position, doctor is influenced very much to the harmony (eye, hand, instrument, tissue) of instrumentation.
But current market sales of tube type anastomat does not have precompression lock function, such as China Patent No.
Disclosed in " bent tube type alimentary canal cervical anastomosis device ", China Patent No. 201220732744.9 disclosed in 201220052990.X
" tubular type kiss disclosed in " pointer member and the circular-pipe anastomat equipped with the pointer member ", China Patent No. 201220732605.6
Clutch ", " circular-pipe anastomat ", China Patent No. 201820041248.6 disclosed in China Patent No. 201210582068.6
" a kind of more indicating window tube type anastomats " etc., without reference to the scheme for how determining pre- identical pressure.Wherein, China Patent No.
201820041248.6 " a kind of more indicating window tube type anastomats " refer to indicating mechanism, although the mechanism can be around stapler
Body rotation, but structure is complicated, also cannot achieve the accurate judgement to pre- identical pressure, doctor is still needed to have superb technical ability
With rich experiences to the spacing of resist-nailed seat and nail bin to determine whether oneself is organized to be adequately compressed or correctly coincide.Because of people
Difference (especially thickness is different) simple Distance Judgment of body intestinal wall or gastric tissue can not react between two parts tissue
The state of fitting.
" circular-pipe anastomat " disclosed in China Patent No. 201220732605.6 has done stapler percussion operation a large amount of
Datail description.
The advantages of tube type anastomat, has very much, such as previous anastomotic no-station pole canopy, anastomosis blood supply is good, anastomosed tissue no inflammation,
Damage, oedema or cancerous tissue residual etc..But in use due to the difference of human body constitution, especially human body intestinal wall stomach function regulating
The tissue thickness of wall is different, and pre- identical pressure is caused (tissue wall to be anastomosed need to be close together, and keep certain pressure
It is able to achieve accurate coincide) need to fully rely on the empirically determined of doctor, it is sometimes desirable to the phase of adjustment resist-nailed seat component repeatedly
Suitable pre- identical pressure is had determined that position, just can be carried out the percussion operation that coincide, low efficiency, operation difficulty are big, are also easy to make
The problems such as at previous anastomotic, Anastomotic bleeding；The great work intensity of doctor is caused simultaneously, and psychological pressure is big.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of pre- identical pressure magnetic induction
Formula tube type anastomat directly reacts the precompression state between intestinal wall to be anastomosed or stomach wall by the design that pressure perceives, directly,
Efficiently, the labor intensity and psychological pressure of doctor are reduced.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: pre- identical pressure magnetic inductive tube type anastomat, packet
