Description
Technical field
The utility model is related to a kind of medical instrument of surgical operation, specifically a kind of novel minimally invasive hysteroscope stapler
Cutter, belong to the field of medical instrument technology.
Background technology
Minimally invasive hysteroscope stapler is primarily adapted for use in abdominal surgery, gynaecology, is organized in paediatrics and thoracic surgery endoscopy surgery
Excision, it is cross-section and identical.Minimally Invasive Surgery is the operation method that a new development is got up, and is that one of the following operation method development must
Right trend.With advancing by leaps and bounds for industrial manufacturing technology, related discipline be fused to carry out new technology, new method established it is firm
Basis, in addition the operation that doctor is more and more consummate so that many past open operations taken by intracavity operation now and
Instead of, surgical selection chance is considerably increased.The method of Minimally Invasive Surgery is to make three 1 centimetre or so small in patient's waist to cut
Mouthful, it is respectively inserted into a pipe-like service aisle for being called " trocar ", later every operation is carried out by these three pipelines；Again
The step same as open surgery is completed under television monitoring with special lengthening surgical instrument, reaches same surgical effect.
Due to the notch very little of human body surface, only 1 centimetre or so, so just having to the flexibility of minimally invasive hysteroscope stapler very high
It is required that while being also had higher requirement to the flexibility and sharpness of the cutter of minimally invasive hysteroscope stapler, existing minimally invasive chamber
There are two types of the cutter of mirror stapler, and one is the cutter of unyielding linear, this cutter use thicker material
Matter, can guarantee the sharpness of cutting, but be unable to flexural deformation, cannot meet the requirement to product flexibility in clinical operation.
