Abstract
The invention discloses a renal puncture needle and belongs to the field of clinical medical appliances. The renal puncture needle comprises a needle body, a transparent casing, a scaled ruler, a needle handle, a push rod, an anaesthesia liquid cavity, a control valve and an anaesthesia pipe, wherein the transparent casing is installed at the periphery of the needle body, the scaled ruler is installed inside the transparent casing, and scales are arranged on the outer side of the scaled ruler; the anaesthesia liquid cavity is installed at the lower part of the needle handle; and the anaesthesia pipe is installed at the lower part of the needle body, the liquid inflow end of the anaesthesia pipe is communicated with the anaesthesia liquid cavity, the liquid outflow end of the anaesthesia pipe is located at the front end of the needle body, and the control valve is installed on the anaesthesia pipe. The renal puncture needle has the beneficial effects that: the defects existing in the prior art are solved; by arranging the transparent casing on the surface of the needle body, the puncture needle can be very clearly distinguished from the kidneys and peripheral tissues in ultrasonic projection, and the puncture accuracy is improved; and by the built-in scaled ruler, the puncture precision is improved, the working difficulty of medical personnel is reduced, and the built-in scales does not cause extra damage and the like to the patient.
Description
Technical field
The present invention relates to a kind of medical instruments, specifically is a kind of kidney puncture needle, belongs to clinical treatment apparatus field.
Background technology
The renal puncture biopsy is a kind of important method of Diagnosis of Renal disease.Be under ultrasonic guidance, to carry out puncture procedure at present clinically mostly; But common puncture needle is very unintelligible in ultrasonic following projection; Be difficult to puncture needle and kidney and surrounding tissue are distinguished; Cause the site of puncture inaccurate, increased work difficulty, also bring unnecessary damage to the patient easily to medical worker.Simultaneously; Employed clinically kidney puncture needle mainly is made up of needle body and needle handle, in the process of puncture, is difficult to the weight of control puncture; Once there was technology scale to be set on the needle body surface; But can increase the frictional force of needle body like this, when puncture, increase patient's misery, and be not suitable for clinical use.
Existing puncture procedure can cause great misery to patient, often need anaesthetize by anesthesia outfit.But existing anesthesia outfit is when anesthesia, and effect is often undesirable, or the anesthesia scope is too big, easily patient is caused adverse effect; The anesthesia position is inaccurate, can't play good anaesthetic effect.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of kidney puncture needle, and it is through being provided with transparent pipe box on the needle body surface; Can be in ultrasonic projection down; Gem-pure puncture needle and kidney and surrounding tissue are distinguished, and built-in rule, the degree of accuracy of puncture can be improved; Reduce healthcare givers's work difficulty, reduce patient's misery.
To achieve these goals, the technical scheme of the present invention's employing is: a kind of kidney puncture needle comprises needle body; Transparent casing, rule, needle handle; Push rod, anesthesia sap cavity, by-pass valve control and anesthesia pipe; The needle body periphery is installed transparent casing, and rule, arranged outside scale on the rule are installed in the transparent casing; The anesthesia sap cavity is installed in the needle handle bottom; The anesthesia pipe is installed in the needle body bottom, and anesthesia pipe liquid feeding end is communicated with the anesthesia sap cavity, and anesthesia pipe liquid outlet is positioned at the needle body anterior end, and the anesthesia pipe is gone up the installation and control valve.
The invention has the beneficial effects as follows and to solve the deficiency that exists in the known technology; Through transparent pipe box being set on the needle body surface, can be in ultrasonic projection down, gem-pure puncture needle and kidney and surrounding tissue are distinguished, improve the accuracy that punctures; Built-in rule can improve the degree of accuracy of puncture, reduce healthcare givers's work difficulty, and built-in scale can not cause additional injuries to patient; The present invention also has following characteristic through supplementary technology: carry anesthesia outfit, can carry out local anesthesia with puncture, the anesthesia precision is high, can reduce the misery of patient when performing the operation, and reduces the untoward reaction that anesthesia brings.
Description of drawings

Fig. 2 is an A-A section structure for amplifying sketch map among Fig. 1.
Among the figure: 1, needle body, 2, transparent casing, 3, rule, 4, needle handle, 5, push rod, 6, the anesthesia sap cavity, 7, by-pass valve control, 8, the anesthesia pipe.
The specific embodiment
To combine accompanying drawing that the present invention is described further below.
As depicted in figs. 1 and 2, agent structure of the present invention comprises needle body 1, transparent casing 2, rule 3; Needle handle 4, push rod 5, anesthesia sap cavity 6; By-pass valve control 7 and anesthesia pipe 8 are installed transparent casing 2, said transparent pipe box 2 in needle body 1 periphery; In ultrasonic down projection, can gem-pure puncture needle and kidney and surrounding tissue be distinguished, improve the accuracy that punctures.Rule 3 is installed in the transparent casing 2; Arranged outside scale on the rule 3, the present invention adopts built-in rule 3, accurately the localised puncture degree of depth; And the smoothness that can keep the puncture needle outside and bodily tissue contact site; Can when puncture, not cause extra damage to health, rational in infrastructure, easy to use.
The present invention is in order to improve anaesthetic effect, and patient's misery when reducing puncture procedure is preferably installed anesthesia sap cavity 6 in said needle handle 4 bottoms, storage anesthesia liquid in the anesthesia sap cavity 6.Anesthesia pipe 8 is installed in needle body 1 bottom, and anesthesia pipe 8 liquid feeding ends are communicated with anesthesia sap cavity 6, and anesthesia pipe 8 liquid outlets are positioned at needle body 1 anterior end, can together get in the human body with needle body 1.Installation and control valve 7 on the said anesthesia pipe 8.Present embodiment is opened by-pass valve control 7 in use, and when needle body 1 thrust the site of puncture, anesthesia liquid flow to the site of puncture along anesthesia pipe 8, carries out local anesthesia, and it is accurate that this embodiment anaesthetizes the position, and the anesthesia scope is little, and is little to injury of human.
