Abstract
The utility model belongs to the field of medical devices and discloses a novel abdominal cavity puncture needle. The scheme of the novel abdominal cavity puncture needle is as follows: an outer sleeve is formed by connecting a needle head with a needle bed through a rubber tube, a needle core penetrates into the rubber tube from the needle bed, a position-limiting handle is arranged at the tail end of the needle core, and a side hole is formed on the needle head. As the needle bed part and the needle head part positioned in the abdominal cavity are connected through the rubber tube, the disturbance action of the needle bed to the needle head is smaller and the risk of injuring organs in the abdominal cavity is further reduced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of novel abdominal paracentesis pin.
Background technology
At present, the abdominal paracentesis pin be mainly used in abdominal paracentesis tap the abdomen inspection, put ascites treating, intraperitoneal and inject Drug therapy etc.The present abdominal paracentesis pin that uses is processed by metal material, and integral body linearly punctures and fixes the often Intraabdominal syringe needle part interlock of drive of back exposed parts, causes the position of syringe needle part to be difficult to fix, and has the danger that injures the abdominal viscera tissue.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, easy to use that this utility model provides, the novel abdominal paracentesis pin that needle end position, puncture back is difficult for touching.
For realizing above-mentioned technical purpose; This utility model is to adopt following technical scheme to realize: a kind of novel abdominal paracentesis pin; Be made up of trocar sheath and nook closing member, it is characterized in that: trocar sheath is formed by connecting syringe needle and the needle stand sebific duct through between the two, and nook closing member is penetrated in the sebific duct by needle stand; The nook closing member tail end is provided with spacing handle, has side opening on the syringe needle.
The utlity model has following beneficial effect: before the puncture, earlier nook closing member is placed in the sebific duct in real time, make trocar sheath linearly; And has certain intensity; Syringe needle punctured nook closing member extracted out to the intraperitoneal correct position, can implement that chemotherapeutics injects or operation such as hydrops drain and since the needle stand part be positioned at Intraabdominal syringe needle and partly link to each other through sebific duct; Needle stand is less to the perturbation action of syringe needle, reduces the risk that injures abdominal visceral browser.
