Abstract
The utility model discloses a puncture needle for abdominal cavities, which comprises a hollow needle body, wherein one end of the needle body is provided with a needle tip and the other end of the needle body is fixedly connected with a needle seat. A needle core, the shape of which is matched with the shape of the needle body, is arranged in a hollow cavity of the needle body. A plurality of radial through holes are arranged on the periphery surface of the needle body, which is adjacent to the needle tip position. The needle tip is provided with a bended part. The utility model solves the problem that a needle tip hole is easily blocked by foreign materials, and has the advantages of easy use, safety and remote possibility of blocking by the foreign materials. Simultaneously, other organs in abdominal cavities are not easily punctured. The utility model is used for clinical diagnosis and treatment of acute abdomen diseases.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of abdominal paracentesis pin.
Background technology
Known a kind of abdominal paracentesis pin comprises needle body and needle stand, needle lumen be provided with one with the suitable nook closing member of its shape.During use, elder generation is to patient's point of puncture local anesthesia, again the needle body tip of needle body is thrust patient's intraperitoneal, connect syringe or negtive-pressure implement through interface then, Intraabdominal liquid or gas are extracted, in the time of need repeatedly extracting, take off syringe or negtive-pressure implement earlier, with the connector insertion needle body cavity of nook closing member from needle stand, Intraabdominal gas of shutoff or liquid; Again nook closing member is extracted, connected syringe or negtive-pressure implement and extract once more.Its shortcoming is first: the needle point pore volume is easily by foreign body obstruction, and influences normal therapeutic; Second: needle point is too sharp-pointed, punctures Intraabdominal other organ easily.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of abdominal paracentesis pin, to solve the needle body tip easily by the problem of foreign body obstruction.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of abdominal paracentesis pin, comprise a hollow needle body, this needle body one end is a needle point, the fixedly connected needle stand of its other end, be provided with the nook closing member suitable with its shape in the cavity of described needle body, described needle body is provided with several radial direction through hole near the side face at needle point place.
Owing to adopted technique scheme, because needle body is provided with several radial direction through hole near the side face at needle point place, when the needle point hole was stopped up by foreign body, Intraabdominal liquid or gas can flow in the needle body cavity by radial direction through hole, are taken away by syringe or negtive-pressure implement.
As a kind of improvement, described needle point has a turn of bilge, and when using abdominal paracentesis to be needled into the abdominal cavity, needle point can directly not faced intra-abdominal organ, thereby is not easy to puncture Intraabdominal other organ.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the structure cutaway view of this utility model embodiment.
The specific embodiment
As shown in drawings, a kind of abdominal paracentesis pin comprises a hollow needle body 1, and these needle body 1 one ends are needle point 11, and needle point 11 has a turn of bilge; The fixedly connected needle stand 3 of its other end, needle stand 3 are provided with hand-held with handle 31, and its effect is: more convenient when holding puncture.Be provided with the nook closing member 2 suitable with its shape in the cavity of needle body 1, described needle body 1 is provided with several radial direction through hole 12 near the side face at needle point 11 places.The side face of needle body 1 is provided with scale, and its effect is: can make medical personnel accurately hold the degree of depth of puncture.
Because needle body 1 is provided with several radial direction through hole 12 near the side face at needle point 11 places, when the needle point hole was stopped up by foreign body, Intraabdominal liquid or gas can flow in needle body 1 cavity by radial direction through hole 12, are taken away by syringe or negtive-pressure implement.Needle point 11 has a turn of bilge, and when using abdominal paracentesis to be needled into the abdominal cavity, needle point 11 can directly not faced intra-abdominal organ, thereby is not easy to puncture Intraabdominal other organ.
