Abstract
The invention relates to a biopsy puncture needle with accurately mastered needle insertion angle and depth. The biopsy puncture needle is provided with a needle handle and a needle head connected with the needle handle, wherein an angle indicator is installed on the needle handle and scales are marked on the needle head. In the use process, when the puncture needle is inclined, a pointer can indicate the inclined angle, so that a clinician can insert the needle while observing the angle at any time, and can accurately observe the needle insertion depth, thus greatly improving the puncture accuracy. The biopsy puncture needle provided by the invention has skillful conception, reasonable design and better economic and social benefits.
Description
Technical field
The invention belongs to technical field of medical instruments, specifically, is a kind of biopsy needle, is particularly suitable for using under the image location condition.
Background technology
The biopsy puncture is one of important diagnosis and treatment means clinically, mainly is for patient's focus is got biopsy, to reach the purpose of check.When carrying out puncture procedure, for can make puncture needle sting comparatively exactly in patient's focus, especially for avoiding mistake to wear the patient vessel, need under the image location, puncture usually, for example measure distance and the angle of entry point, and then carry out puncture procedure to patient's focus by CT scan.But existing puncture needle can not be indicated the angle of inserting needle, the clinicist can only rely on individual's experience to determine needle angle like this, be difficult to the angle of inserting needle is accurately held, the number pin that often needs to puncture just can be worn middle focus, for the doctor who lacks experience, the difficulty more that operates had both caused the damage of normal structure and unnecessary misery to the patient, also prolong the time of puncture procedure, also may cause doctor-patient dispute thus.In addition, the mark of existing its depth of needle of biopsy needle is also clear and definite inadequately, has also caused the inconvenience of operation thus.
Summary of the invention
The purpose of this invention is to provide a kind of biopsy needle that can under the image location condition, use, use this biopsy needle, can hold the angle and the degree of depth of inserting needle comparatively exactly, easy to use.
For achieving the above object, technical scheme of the present invention comprises needle handle and the syringe needle that is connected on the needle handle, it is characterized in that the angle indicator is installed on the needle handle, and syringe needle is marked with scale.
Said angle indicator comprises table body, dial plate and pointer, and described pointer relies on the gravity of self to remain state perpendicular to the ground.The angle indicator is installed on a side of needle handle, and when syringe needle was in state perpendicular to the ground, the angle of pointer indication was zero.Described dial plate can be semicircle.The scale subscript of syringe needle is marked with Arabic numerals.
The present invention is skillfully constructed, and is reasonable in design.It is the instrument that installation one can be indicated angle on the needle handle of puncture needle, the pointer of instrument is indicated direction perpendicular to the ground all the time by self gravitation, when puncture needle tilts, pointer can indicate the angle that tilted, like this clinicist can be under the situation of viewing angle at any time inserting needle, and syringe needle of the present invention is marked with scale, and be marked with Arabic numerals at the scale subscript, the clinicist can grasp the degree of depth of puncture exactly, and the puncture accuracy rate is improved greatly, and general one-time puncture can be successful, both can reduce the injury that patient's normal structure is brought by puncture, alleviate patient's misery, can shorten the puncture time again, puncture procedure is standardized more.In the piercing process, also can cooperate the support bracket fastened use of puncture needle, puncture needle is fixed on the site of puncture, rock when avoiding carrying out image scan and be shifted, further reduce damage patient.The present invention and existing puncture needle are carried out the clinical comparison test, use existing lancet puncture patient 80 examples, one-time successful puncture rate only is 20%, and uses lancet puncture patient's 90 examples of the present invention, and one-time successful puncture rate reaches 99%.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
Concrete real-time mode
With reference to accompanying drawing, the embodiment of the invention has needle handle 1, is connected with syringe needle 2 on it, and angle indicator 3 is installed on the needle handle 1.Described angle indicator is installed on a side of needle handle 1, and it comprises table body, semicircle dial plate and pointer 4, and pointer 4 relies on the gravity of self to remain state perpendicular to the ground.When syringe needle 2 was in state perpendicular to the ground, the angle of pointer 4 indications was zero.Syringe needle 2 subscripts are marked with scale, and are marked with Arabic numerals at the scale subscript.The present invention can adopt one-time formed mode processing and fabricating.In the use, when puncture needle tilted, pointer can indicate the angle that tilted, like this clinicist can be under the situation of viewing angle at any time inserting needle, the degree of depth that can observe puncture exactly simultaneously improves the puncture accuracy rate greatly.The present invention also can cooperate the support bracket fastened use of puncture needle, and puncture needle is fixed on the site of puncture, rocks when avoiding carrying out image scan and is shifted.
