Abstract
The utility model discloses a tube placing instrument for puncture of abdominal cavity, which is used in ventriculo-peritoneal shunt. The tube placing instrument comprises a sheath which contains a puncture needle. A top end of the puncture needle penetrates the sheath. One end of the puncture needle, which is far from the top end, is fixedly provided with a fixing cap. The fixing cap is detachably connected with the sheath. One end of the sheath, which is next to the top end of the puncture needle, is provided with a chamfer; and the other end of the sheath is provided with screw thread. The sheath is provided with scales. The setting of scales facilitates observing to the insertion depth for preventing danger. The setting of the chamber facilitates the insertion of the tube placing instrument. The tube placing instrument for puncture of abdominal cavity has the advantages of simple structure and convenient use. The fixing cap is detachably connected with the sheath, and the pulling of the puncture needle is facilitated.
Description
Technical field
This utility model relates to and is used for a kind of abdominal paracentesis tube placing device that v p shunt is used, and belongs to medical apparatus and instruments.
Background technology
In v p shunt in the past, must open abdomen when ventricles of the brain peritoneal shunt pipe abdominal end is inserted the abdominal cavity places, upper abdomen otch 10～15cm, wound is big, and easily cause the complication of abdominal, as intestinal adhesion, infection of incisional wound etc., the abdominal cavity less invasive techniques has overcome this shortcoming in recent years, and the abdominal cavity less invasive techniques need be used the abdominal paracentesis tube placing device, traditional abdominal paracentesis tube placing device, the complex structure troublesome poeration is not suitable for promoting the use of, and the bad assurance of the degree of depth of puncture, the dark internal organs of damage easily punctured.
The utility model content
The technical problems to be solved in the utility model is the deficiency at technique scheme, provides simple in structure, safe a kind of abdominal paracentesis tube placing device easy to use.
For solving the problems of the technologies described above the technical solution of the utility model be:
A kind of abdominal paracentesis tube placing device comprises the sheath cover, accommodates puncture needle in the described sheath cover, and the tip of described puncture needle passes outside the sheath cover, and the end away from the tip on the puncture needle is fixed with locking cap, and locking cap and sheath cover removably connect.
Below be to further improvement in the technical proposal:
The end that sheath puts near the puncture needle tip has chamfering, and the other end has screw thread, and described sheath puts and is provided with scale.
Graduatedly the convenient insertion depth of observing be set prevent danger, chamfering the insertion that makes things convenient for tube placing device is set.
Described locking cap cooperates with the sheath external threading.
The outer surface of sheath cover is fixed with handle.
Being provided with of handle conveniently held and puncture.
During use,,, turn on locking cap after finishing puncture, extract puncture needle, place the mozzle process of finishing the work then then with whole tube placing device insertion patient abdominal part earlier with locking cap and sheath cover.
Adopt technique scheme, this utility model is simple in structure, and is easy to use, and locking cap and sheath cover removably connect and make things convenient for the extraction of puncture needle.
Below in conjunction with drawings and Examples technique scheme is described further.
