Description
Technical field
The utility model is related to surgical tissue specimen fetching technical field more particularly to a kind of disposable specimen fetchings
Device.
Background technology
With being constantly progressive for human medical's technology, hand is had become by the endoscope minimally invasive operation of representative of laparoscopic surgery
The trend and mainstream of art development.Currently, domestic laparoscopic surgery amount is in the situation of cumulative year after year, not only more and more hospitals have
The standby technology and condition for carrying out laparoscopic surgery, and it is continuous consummate and perfect with surgical technology so that the past
Many open surgeries are replaced by endoscope-assistant surgery.Relative to traditional operation, laparoscopic surgery has, pain small to patient trauma
The features such as bitter light, postoperation recovery is fast.But in laparoscopic surgery, for how safety thoroughly takes out operation excision object, avoid
Residual is always a key points and difficulties, this is not only directly related to the success or failure of whole laparoscopic surgery, is also relate to patient's
Postoperative rehabilitation.In a very long time, domestic laparoscopic surgery is opened there is no the medical instrument taken out specifically for excision object
Opening up the hospital of laparoscopic surgery can only use self-control gloves or self-control polybag to complete this key after simple processing disinfection
One step of property.Such self-control gloves or self-control polybag make trouble, and are difficult to ensure and take out operation excision object for a full due,
It avoids residual and load-engaging device damaged, therefore there are larger infection and residual risk, inconvenience is brought to operator
And hidden danger.
There are many specimen fetching devices on the market at present, as the Chinese utility model of Patent No. 201320278204.2 discloses
A kind of disposable specimen fetching device, including hollow pull rod A and the setting of hollow ends pull rod B, the pull rod A
Have and be provided with handle B on the outside of the ends handle A, the pull rod B, the pull rod B is interspersed in the pull rod A, described
Pull rod B is fixedly arranged at the front end with memorial alloy ring, and extraction bag is connected on the memorial alloy ring, is arranged in a organized way in pull rod B
Fixed locked guiding mechanism.But such design is needed A, B bar while being extracted out when finally shrinking sack, extraction bag packet
Tissue substance shrinkage is wrapped up at incision of abdominal wall, when tissue block is slightly larger, needed vessel forceps by having been flattened by abdominal wall tissue
Sack little by little takes out tissue, and operation is very difficult, and has the risk for clipping broken sack.
Utility model content
The purpose of this utility model is that for the above-mentioned deficiency of the prior art, proposes that one kind is easy to operate, takes object rapid
And also it can smoothly be taken out when success rate is high, tissue block is larger, bag body is not easy the disposable sample of shrinkage and rupture
Take sundries.
