The serous cavity of human body only has a small amount of liquid under normal circumstances as thoracic cavity, abdominal cavity, pericardial cavity etc., at the main lubricate of intracavity, generally not easily collects.Then may have volume fluid retention in pathological conditions and form serous cavity liquid, clinician's row pleurocentesis, peritoneocentesis or pericardiocentesis gather the hydrops of different parts respectively.At present, clinical conventional be conventional needle, doctor is difficult to when operating hold paracentesis depth, and performance accuracy is limited, easily causes the damage of important organ, brings larger misery to patient.In order to ensure performance accuracy from apparatus structure, need a kind of piercing needle rational in infrastructure.
Utility model content
The purpose of this utility model is the accuracy in order to ensure paracentesis depth, and spy provides a kind of serous cavity sting device with controlling depth of needle.
This utility model provides a kind of serous cavity sting device with controlling depth of needle, it is characterized in that: described with the serous cavity sting device that can control depth of needle, comprise rear end sleeve pipe 1, front end sleeve pipe 2, flexible sleeve 3, special-shaped screw 4, link 5, indicating graduation labelling 6, Screw 7, puncture needle 8;
Wherein: rear end sleeve pipe 1 is the hollow structure of two symmetrical structure compositions, connects into a sleeve pipe entirety by Screw 7; Sleeve pipe entirety is enclosed within puncture needle 8;
The lower end of rear end sleeve pipe 1 and the upper end of front end sleeve pipe 2 are socketed, and the internal diameter of rear end sleeve pipe 1 is greater than the external diameter of front end sleeve pipe 2;
The middle and upper part of special-shaped screw 4 is with the outstanding structure of ring-type, and the side of rear end sleeve pipe 1 is with the boss 101 stretched out, and boss 101 inside is with annular recess; The outstanding structure of the ring-type of special-shaped screw 4 freely can be rotated and be realized axially blocking in annular recess;
The lower end of front end sleeve pipe 2, with ring-type limit structure, ring-type limit is fixed with link 5, link 5 is threaded hole, and screwed hole and special-shaped screw 4 are connected;
The side of front end sleeve pipe 2 is with indicating graduation labelling 6.
Described with the serous cavity sting device that can control depth of needle, also comprise flexible sleeve 3, flexible sleeve 3 is enclosed within the inside of front end sleeve pipe 2.
Before using, for the degree of depth that different patient need puncture, adjustment special-shaped screw 4, realizes regulating the socket degree of depth between rear end sleeve pipe 1 and front end sleeve pipe 2, controls the exposed length of puncture needle 8 needle point.
Advantage of the present utility model:
Serous cavity sting device with depth of needle can be controlled described in the utility model, theory structure is simple, and the needle point exposed length of puncture needle easily realizes accurate control, be conducive to carrying out smoothly of puncture, facilitate doctor to operate, reduce the risk of damage important organ, alleviate the misery of patient.
