Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of puncture needle.
Background technology
Plays lubrication containing a small amount of liquid (10-15mL) in the pleural space of normal person, in negative pressure in pleural space, chest fluid leach and absorption is in dynamic equilibrium.When pleural space endogenous cause of ill hydrops or pneumatosis form high pressure, lung tissue meeting atrophy, function reduction.Hydrops in pleural space or pneumatosis can cause in drainage bottle by closed drainage of pleural cavity, intrapleural pressure power is made to recover normal, thus lung tissue is opened and restore funcitons again, playing a very important role for treatment hemothorax, pneumothorax, empyema, is one of Diagnosis and Treat means that thoracic trauma etc. is commonly used.
The common tool of current closed drainage of pleural cavity is puncture needle, mostly is solid construction.After the method adopted is generally and determines otch, doctor finds the gap inserting needle of patient's intercostal, and solid puncture needle is directly thrust skin by otch, need to rely on personal experience, confirm site of puncture, then drainage tube is inserted along puncture path direction, take out puncture needle.Such operation has blindness, and paracentesis depth should not be grasped, and experience doctor generally must be had to operate.Sometimes obese patient intercostal space is not obvious, not easily finds and localised puncture point, likely causes puncture path and be separated not in same path, thus cause the postoperative untoward reaction of subcutaneous emphysema, subcutaneous hemorrhage.
Utility model content
In order to solve the problems referred to above that prior art exists, this utility model provides a kind of puncture needle.
The technical scheme that this utility model adopts is:
A kind of puncture needle, comprise piercing portions and grip portions, described piercing portions and grip portions are hollow, and described piercing portions comprises needle body and syringe needle, and described syringe needle is arranged on one end of described needle body, and described grip portions is arranged on the other end of described needle body.
Further, described syringe needle comprises pinhead handle and needle point, and described needle point is connected to the first end of described pinhead handle, and described syringe needle is arranged at one end of described needle body by the second end of described pinhead handle, and described pinhead handle is cylinder, and external diameter is not more than needle body external diameter.
Further, described grip portions comprises needle holder and needle holder handle, and described needle holder handle and needle holder are connected to one end of described needle body successively.
Further, described needle body is provided with some conduction holes.
Preferably, described hollow internal diameter is for being greater than 2mm.
Preferably, described needle holder handle outer wall is provided with the draw-in groove that medical guiding wire established by card.
Preferably, described piercing portions adopts aluminum alloy material.
The beneficial effects of the utility model are: make traditional solid puncture needle into hollow puncture needle, hollow internal diameter is arranged to be greater than 2mm, to implant medical guiding wire, locate in advance by medical guiding wire, easy and simple to handle, reduce the difficulty of operation, the accuracy of Needle localization can be improved, increase success rate, reduce the misery of patient and postoperative untoward reaction.Body sections is provided with some conduction holes, can increase drainage, prevents from forming thromboembolism.Piercing portions adopt aluminum alloy material have body gently, not corrosion, be not easy to bend, the features such as good rigidly.

Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of puncture needle, comprise piercing portions and grip portions, described piercing portions comprises needle body 2 and syringe needle, described piercing portions and grip portions are hollow-core construction, described syringe needle is arranged on one end of described needle body 2, and described grip portions is arranged on the other end of described needle body.Described syringe needle comprises pinhead handle 102 and needle point 101, and described needle point 101 is arranged at the first end of described pinhead handle 102, and described syringe needle is arranged at one end of described needle body 2 by the second end of described pinhead handle 102.In order to reduce the damage to patient body, described needle body 2 and pinhead handle 102 are cylinder, and pinhead handle 102 external diameter is not more than needle body 2 external diameter.Described grip portions comprises needle holder 302 and needle holder handle 301, and described needle holder handle 301 and needle holder 302 are connected to one end of described needle body 2 successively.Medical guiding wire is fastened on the outer wall of needle holder handle 301 by draw-in groove 5, can completely take, and medical guiding wire takes off by operation consent from draw-in groove 5, handled easily.
Doctor is when carrying out closed drainage of pleural cavity, after selecting point of puncture according to the situation of patient, local anesthesia is carried out in sterilization, try on the Syringe injector of implantable seal wire, after sucking-off gas or liquid, implant medical guiding wire, skin and subcutaneous tissue is scratched successively along direction, intercostal space with knife blade, implant skin dilator, along the direction of medical guiding wire, doctor's hands holds grip portions, in turn the syringe needle of puncture needle and needle body 2 are sent into focus, protector fixing plan penetration depth part is fixed with silica gel, take out medical guiding wire, remove silica gel and fix protector, complete the operation of closed drainage of pleural cavity.
The needle body 2 of puncture needle is provided with some conduction holes 4, can increase drainage, and hydrops or pneumatosis, not only by needle point 101, more enter needle body 2 by conduction hole 4, excrete smoothly, effectively can prevent thromboembolism.
Described syringe needle and needle body 2 adopt aluminum alloy material, have body gently, not corrosion, be not easy to bend, the features such as good rigidly.
In order to other puncture instruments existing with the use of, the hollow puncture needle that this utility model provides, can be made into 16F, 20F, 22F tri-kinds of specifications; In order to make medical guiding wire pass through smoothly in hollow, the hollow internal diameter of puncture needle is for being greater than 2mm.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
