Description
Technical field
The utility model is related to medical instruments fields, and in particular, to a kind of electronic hysteroscope stapler.
Background technology
It is medical since invention the 1960s first staple class product in the surgical operation of medical science
Stapler has become the essential a kind of medical instrument aided in edge of a knife sewing process.Development with medicine and product
Research and development, more and more multi-functional staple class products application is in clinic.The scope of application has been directed to gastrointestinal surgery, liver and gall surgical department, chest
The every field such as surgery, Urology Surgery, gynemetrics become one of essential tool of doctor.For patient have art in compared with
Few bleeding, less operating time, with instrument replaces by hand to reduce due to manual and caused by error, avoid infection, postoperative
A variety of advantages such as functional rehabilitation is fast.
Traditional surgical operation includes cutting, separation, ligation, hemostasis, suture, eventually arrive at excision to organ lesion and
The reconstruction of organ.Mechanical staplers can replace traditional operation, by three basic operations realize diseased organ excision and
It rebuilds.
1, separate：Organ is sutured away from lesion certain distance using linear staplers, including parenchymatous organ and
Cavity organ, blood vessel etc., then detachment cuts off diseased organ, or once completes suture and detachment using linear incision stitching unstrument.
2, the tissue apposition sutured will be needed, with linear staplers stapling, such as the longitudinal sectional transverse joint at pylorus, is completed deep and remote
Door plasty.
3, with anastomosis ring applicator, can cavity organ such as oesophagus, stomach, small intestine, colon be subjected to end end kiss very conveniently
It closes, end-to-side anastomosis.Stomach and intestine side to side anastomosis is carried out using stapler.Such as nodus hemorrhoidalis end-to-end intestinal anastomosis, gastric and esophageal end side
Anastomosis and stomach jejunum side-to-side anastomosis etc..
The special stitching unstrument of hysteroscope at present, i.e., various hysteroscope staplers.This stitching unstrument shares six row's staples, has in nail kit complete
New blade, blade cuts off tissue from centre while stitching, and each three rows staple in both sides is made to complete suture, the functions such as hemostasis.
At present in actual use, there are mainly of two types for the special stitching unstrument of hysteroscope.It is another one is manual hysteroscope stapler
Kind is electronic hysteroscope stapler.
Manual hysteroscope stapler is mainly to realize the advance of cutter by rack and percussion impelling sheet, and retreat and need manually
It retracts.The opening and closing of nail bin groupware, the knife pin on cutter push the inclined-plane on resist-nailed seat to realize beating for resist-nailed seat
It opens and is closed.Relatively easy from total but complicated for operation, the stability of instrument at work is bad, percussion force size
Variation is apparent, when instrument is driven it is fast with it is bigger by influencing manually slowly, especially everyone grip difference in size it is larger, tie
Fruit is that the speed when cutter cut tissue is sometimes fast and sometimes slow, it is easy to cause the tissue surface cut uneven, the speed of pushing slice of nail
Degree similarly exists sometimes fast and sometimes slow, it is easy to the problems such as causing nail type bad, it is easy to influence the final effect of operation.
Electronic hysteroscope stapler includes the compositions such as battery feed, circuit control system, motor, transmission system.Pass through machine
The combination of electricity, operation become simple, can well control device work when stability, using widely being promoted.Specifically
Ground, existing electronic hysteroscope stapler include power supply, the first microswitch, the second microswitch, motor, transmission mechanism and lead screw,
Wherein：Power supply, the first microswitch, motor form motor forward control circuit, and the rotating forward of the first microswitch control motor is opened
Dynamic, the rotating forward of motor drives lead screw forward axial motion by transmission mechanism；Power supply, the second microswitch, motor form motor
Reverse turn control circuit, the reversion that the second microswitch controls motor start, the reversion of motor by transmission mechanism drive lead screw to
After be axially moved, the front and back axial movement of lead screw can drive the swivel head of anastomat nail storehouse component to swing.During use,
Manually opened first microswitch, lead screw forward axial motion move to certain distance and the first microswitch, lead screw are turned off manually
Stop forward axial motion；Manually opened second microswitch, lead screw backward axial movement move to certain distance and are turned off manually
Second microswitch.Such electronic hysteroscope stapler has problems in that：（1）The front and back dwell time being axially moved of lead screw needs
It is high to personnel control required precision by manually controlling.（2）The frequency of use of microswitch is high, and increased wear, reliability reduce.
It can be seen that above-mentioned existing hysteroscope stapler is in structure, method and using upper, it is clear that there are still have it is inconvenient with it is scarce
It falls into, and needs to be further improved.How to found it is a kind of it is safe and reliable, control accuracy is high, is not easy to be affected by human factors
New electronic hysteroscope stapler, becoming current industry pole needs improved target.
