Insufflation needles are already known in various designs, see ζ.

The mechanism of the needle with a spring is designed in such a way that a blunt ".and r in (hollow needle) is pushed forward by a sharp inclusion needle with spring force about 1 cm. As soon as the sharp had el: -, ρ it se the abdominal wall and the abdomen pierce the child, the blunt stylet jumps forward, so that with v ^.: ej t moving the insufflation needle no f. injuries ie: Dar: *.

The first disadvantage is to be seen in the fact that the needle is about 1 zn in Lurch ::.

The wide disadvantage is that the measurement of the current static intradonial pressure about 5 to 3 mn behind the outlet opening for the . insufflated Gaa is Zs is as follows: r.it the possibility that the region of the needle does not Kits rr.it ui inungen both the insufflation dhrit flationsöffnung and d-ir Me ^ öifnung sits in the 3-asblase, veil is dazv / een E.g. the peritoneum, an arterial bz ¹ :;. t, while he .T. with a high pressure the gas directly in egg n vessel, in an intestine or in an intergrowth niche.

The needle according to the innovation is free from the drawbacks of the known needles and is shown in the accompanying illustration . First of all, the needle in the mandrin 5 ″ with a rounded tip has two outlet openings 6, δ ′, which are spaced apart from one another are arranged opposite each other behind the rounded tip.

ser of the trocar 3 of only 2: rm the Einotrömungswiderotand for
Carbonic acid and NC gas to be lowered to about 2 mm of mercury. The trocar 3 is displaceable on the mandrin 5 and carries a cutting edge with a point on one side and an innd-riff 2 on the other side, which is under the action of fire. the
Handle 2 is on the one hand on a r. Hollow cylinder 4 and on the other hand with the trocar 3 guided on the mandrin. The cylinder spring in the handle 2 sor ^ t for it, ia;?. the point at the edge
of the trocar 3 in its rest position is always held above the outlet openings 6, 6 '. One side of the hollow cylinder 4 can be screwed into a threaded hole of the mandrel ^ . On the other side of the cabbage cylinder 4 is a Y-shaped tap 1 with an inlet port 7 for measuring the
Insufflation back pressure as well as with an inlet port 8 for
the measurement of the current static intradominoll pressure
urd arranged with a handle 9, which can be rotated in three positions:

Position to the left: Connection connecting piece 7 with

Stylet 5,
Position to the right! Connection of connecting piece 8 with

the stylet 5,

Middle position: neither connection with 7 or 8, more complete

Gas stop.

Other advantages of the new needle: Hit the handle 2 can
the trocar 3 can be rotated into any position
the two openings 6, 6 'of the mandrin are never covered by the sharp edge of the trocar 3. Furthermore, it is possible that when using different insufflation needles, every trocar fits every needle, since it does not matter what the needle tip of the trocar is After screwing in the stylet, it does not cover the openings 6,6 'in any position.

The Ir.sufflation needle according to the innovation can be different

for

amniocentesis is also well suited, i.e. zurr. Piercing The 3-ebärnutterv / and for sucking off amniotic fluid, for e.g. 3 genetic prenaeal diagnostics.
