Summary of the invention
The object of the invention is exactly for the sealing member that overcomes existing housing can not rotate with the operation apparatus, causes the defective of Intraabdominal gas leak, and a kind of universal abdominal paracentesis device is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of universal abdominal paracentesis device; Comprise housing with black box; The housing rear end is provided with the puncture shell, and a puncture needle is stretched into by the housing front end and passes black box in the puncture shell, and it is characterized in that: the housing front end is fixedly connected a spherical connector spare; Spherical connector spare has the through hole that axially runs through, and is used for the insertion of puncture needle; The front end of spherical connector axially cooperates with a ball cup, and ball cup constitutes universal the connection with spherical connector, and ball cup has the through hole that axially runs through, and is used for the insertion of puncture needle; The front end of ball cup axially cooperates with an elastic sealing element, and elastic sealing element has the axial seal hole, is used for forming sealing in the periphery of puncture needle; The front end of elastic sealing element is provided with gland, and gland has the through hole that axially runs through, and is used for the insertion of puncture needle, and gland is fixedly connected with ball cup.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
The rear end of ball cup is connected with a binding ring, and binding ring is sleeved on the spherical connector, and ball cup is remained and being connected of spherical connector.
Be provided with sealing ring between annular seating and binding ring, last ring set is used for forming sealing in the periphery of spherical connector on spherical connector.
Elastic sealing element is the sealing member with arc hermetically-sealed construction.
The invention has the beneficial effects as follows that the front end through spherical connector axially cooperates with a ball cup; Elastic sealing element can be rotated with the puncture shell relatively; Insert in the abdominal cavity rotating process at medical apparatus and instruments, elastic sealing element can rotate along with medical apparatus and instruments, makes elastic sealing element form effective seal in the periphery of medical apparatus and instruments; Can deformation because of the rotation of medical apparatus and instruments, avoid leaking of gas.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
