Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of puncture needle.
Background technology
The purpose of pleurocentesis is to clarify a diagnosis and alleviates the pressure of internal organs, and its main operational steps is: (1) is in selected point of puncture inserting needle local anesthesia; (2) whether the detection puncture needle is unobstructed, prepares puncture; The doctor punctures at point of puncture, slow inserting needle during puncture, when the degree of depth shown in inserting needle to B ultrasonic is located, the pumpback of trying as extracting out without gas or liquid, can continue suitable inserting needle, extract out if any gas or liquid, stop continuing inserting needle, the intrathoracic gas of suction or liquid, complete puncture under assistant's assistance; When (4) needing to intrapleural injection after puncture is complete, need to use syringe to be connected with puncture needle, inject medicinal liquid; (5) carry out afterwards post surgery treatment.
As shown in Figure 5, existing puncture needle comprises puncture needle tubing 201 and the connection tube 202 that is connected with described puncture needle tubing 201.existing puncture needle is after thrusting the inside in thoracic cavity, if a people aspirates the work of intrathoracic gas or liquid, need to connect syringe at the tail end of described connection tube 202, and in connecing syringe or using the process of syringe pump, swinging can appear in described puncture needle tubing 201, can't stablize, may be to patient's intrathoracic organ injury, therefore, connect the process of syringe or use syringe pump, need to be in assistant's assistance, and in the process of assisting with the assistant, if inharmonious with assistant's co-operate, make puncture needle unstable, puncture needle can damage intrathoracic organ.And when intrathoracic gas or liquid were taken out fewer and fewer, visceral pleura was more and more pressed close to parietal pleura, and the doctor needs the position of conversion needle tip often as thinking extracting gases as far as possible or liquid, easy like this visceral pleura, internal organs was damaged.If the intrathoracic hydrops amount of patient is few, the point of puncture position so more easily damages on the lower side or site of puncture when closing on vitals or blood vessel.Moreover when patient's cough, heartbeat or position change, puncture needle also can be to intrathoracic organ injury.
The utility model content
The purpose of this utility model is to provide a kind of puncture needle, and easy damaged thoracic cavity internal not when using this puncture needle to carry out thoracentesis needle is safe.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of puncture needle comprises puncture needle tubing, protection nook closing member and connection tube;
The head of described puncture needle tubing is pointed, and the sidewall of head is provided with at least one hole;
Described protection nook closing member is hollow structure, and the head of described protection nook closing member is smoothly blunt nosed for sealing, and the sidewall of head is provided with at least one hole;
