Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of locking double-jacket tube medical safe puncture needle.
Background technique
Surgical operating instrument has had centuries history, and doctor completes tissue with different surgical instruments in surgical operation
Crawl is sheared, separation, blood coagulation, and the operation such as suture closure, surgical operating instrument develops mature by centuries.Hysteroscope hand
The clinical of art is carried out more than 30 years, just in rapid advances.Briefly, endoscope-assistant surgery, that is, operative doctor is using the hysteroscope lengthened
Hand-held apparatus enters patient's body via the puncture channel of natural cavity or building, completes tissue crawl, shears, separate, coagulates
Blood, the operation such as suture closure.
Laparoscopic surgery is being carried out, most common instrument is veress needle, drainage needle and infusion double sheathed needle.Traditional puncture
Needle includes outer needle, interior needle, and interior needle can be in the interior movement of outer needle；In use, one hand-held puncture needle of doctor, another hand is in patient
Abdomen determines position, determines behind position that puncture needle is acted on patient abdomen by doctor, at this time the interior needle syringe needle of puncture needle first with suffer from
Person's skin contact, due to interior needle syringe needle be it is blunt nosed, contact patient skin after, patient skin can not be pierced through and enter abdominal cavity of patients
It is interior；Doctor continues to apply downward power to abdominal cavity of patients direction, and the internal needle of patient skin imposes upward power, is retracted to it outer
In needle.After interior needle syringe needle is fully retracted into outer needle, outer needle needle contact patient skin simultaneously pierces through patient skin, into patient's abdomen
Chamber.
Veress needle penetrates each layer tissue of stomach wall, and each layer tissue penetrated includes that skin, subcutaneous tissue, subcutaneous layer of fat are subcutaneous
Muscle layer, peritonaeum.Wherein, peritonaeum is especially fine and close, and toughness is stronger, since resistance declines suddenly when puncture needle penetrates peritonaeum, breaks through sense
It is extremely strong；Existing puncture needle, can not safe self-locking when penetrating stomach wall, it is easy to the damage of abdominal cavity inner tissue or internal organs be caused to lead
Cause unexpected occur.A kind of puncture needle of urgent clinical needs, can be self-locking by puncture tip when penetrating stomach wall, avoids to intraperitoneal group
It knits or organ causes to damage.
