Abstract
The utility model discloses a safety medical puncture outfit, comprising a puncture needle, a tube and an elastic device; wherein the puncture needle is hollow, a tube core at the front of the tube penetrates through the puncture needle and is exposed outside the puncture needle, and the elastic device is fixed on the body of the tube. Compared to the prior art, the safety medical puncture needlehas the advantages of simple structure, easy use, noninvasive operation, safety and good effect.
Description
Technical field
This utility model belongs to technical field of medical instruments, more specifically relates to a kind of safety medical thrust device.
Background technology
The drawing liquid utensil that uses for the puncture treatment of cardiothoracic surgery is that the syringe front portion is with puncture tube at present, and the puncture pipe end is equipped with syringe needle, and syringe needle thrusts affected part, and the operation syringe extracts the liquid of affected tissue.There is following weak point in this device:
1. its sharp-pointed needle point tends to bring the damage of some pulmonarys, especially it is less to work as hydrothorax, perhaps hydrothorax is sucked out major part, and when perhaps ultrasonic diagnosis was wrong, expansible pulmonary tended to by sharp keen puncture needle damage, this situation is elderly patients, the critical patient or and to merge the probability that patient's (as the big kitchen of lung, chronic obstructive pulmonary disease etc.) of basic pulmonary illness takes place on one's body bigger, pneumothorax can appear, hemopneumothorax, consequence is quite serious sometimes.It is reported pneumothorax to occur behind the thoracentesis, the incidence rate of hemopneumothorax can reach 7.5%.
2. when operation needs two people to operate simultaneously, and when syringe is pulled out from rubber tube, when the liquid in the syringe was pushed away sky, the assistant need close rubber tube with the blood vessel clamp, in case the air admission thoracic cavity.In addition, when liquid more for a long time, need to extract repeatedly repeatedly, complex operation can't be finished simultaneously and insert the purpose that drainage tube reaches long-term drain.
The utility model content
The purpose of this utility model is to overcome the weak point that prior art exists, and a kind of safety medical thrust device is provided.
For achieving the above object, this utility model has been taked following technical scheme:
Safety medical thrust device comprises puncture needle, conduit and elastic device; Described conduit is successively by tube core, and outer cover bobbin and tube head connect and compose; Puncture needle is a hollow, is positioned at the forward tube core of conduit and sees through puncture needle, and the head of tube core exposes outside puncture needle; Elastic device is fixed on the body of conduit.Can avoid damaging tissues such as pulmonary so when in use.
As improvement of the technical scheme, the syringe needle of puncture needle is the inclined-plane, is tip shape.
As improvement of the technical scheme, the head of tube core is a hollow, is blunt nosed shape.
As improvement of the technical scheme, on the tube head of conduit, also be provided with a controlled valve device.
The operator takes out syringe when completely needing the emptying syringe, does not need the assistant to help folder to close and prevents the air admission thoracic cavity, only valve closing need be got final product.
In addition, can insert drainage tube, realize the effect of constant drainage by nook closing member.
As improvement of the technical scheme, be fixed into one between puncture needle and the conduit by being threaded.
As improvement of the technical scheme, described elastic device is a spring.
As improvement of the technical scheme, described tube core is located in the outer cover bobbin, and its afterbody is butted on the afterbody of overcoat bobbin by spring.
Compared with prior art, the more traditional thoracic-puncture needle of this utility model is significantly improved, and has simple in structurely, easy to use, avoids damage, diverse in function, and advantage such as respond well if can necessarily can become doctor's good assistant at clinical expansion, benefits patient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with Figure of description,
Fig. 1 is a structural representation of the present utility model; Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
As shown in Figures 1 and 2: safety medical thrust device comprises puncture needle 1, conduit 2 and elastic device 3; Puncture needle is a hollow, is positioned at the forward tube core 21 of conduit and sees through puncture needle, and expose outside the syringe needle 11 of puncture needle; Elastic device is fixed on the outer sleeve 22 of conduit.
As improvement of the technical scheme, 23 also are provided with a controlled valve device 4 on the tube head of conduit.
Improve as the another kind of technique scheme, be fixed into one between puncture needle and the conduit by being threaded.
Described elastic device is a spring.
When this utility model used in puncture, owing to be positioned at the forward tube core of conduit through behind the puncture needle, the head of tube core exposed outside puncture needle, the about 0.5cm of outstanding trocar sheath syringe needle under its blunt nosed normal condition, meet obstructions in the regracting overcoat bobbin of back, when resistance disappears, can eject automatically.
Like this, when hand-held overcoat bobbin punctures, the internal die withdrawal that meets obstructions, when thrusting the thoracic cavity, after the resistance disappearance that soft tissue brings, internal die ejects automatically, has blunt nosedly replaced sharp-pointed syringe needle, can effectively reduce the pulmonary lesion that may bring.
And, wear behind this puncture needle one can switch valve, when the syringe suction is full of hydrothorax need be discharged the time, as long as valve-off, do not need as traditional thoracic-puncture needle assistant of needs to help the clamp rubber tube in order to avoid the air admission thoracic cavity is simple and convenient with vascular forceps.Can penetrate the thoracic cavity from backshank with the flexible plastic tube of this puncture needle size coupling by one in addition, to make the usefulness of long-term drain.
