Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a spinal tumor biopsy puncture needle.
Background
Spinal tumors (spinal tumors) refer to primary and secondary tumors that occur in the spine. The overall incidence of primary spinal tumors is approximately 0.4%. Most juvenile spinal tumors are benign, while middle-aged and young patients have a high probability of malignant tumors. Benign tumors usually involve the posterior structures, while malignant tumors usually involve the vertebral bodies. Primary benign spine tumors generally progress slowly and have a long course of disease; malignant spine tumor has rapid progress, short course of disease and rapid clinical symptoms, and accounts for about 10% of newly-added malignant bone tumor every year.
The spinal tumor is taken as a common orthopedic disease, correct diagnosis is particularly important for treatment and patient prognosis evaluation, and currently, biopsy for pathological diagnosis is one of the most important examinations for diagnosis of spinal tumor.
The existing spinal puncture biopsy defects: the puncture hollow trephine or the threaded solid drill can not take out the focus of some patients when the focus of the patients has serious bone destruction or relatively less bone content or obvious hardening.
Disclosure of Invention
The invention aims to provide a spinal tumor biopsy puncture needle, which is used for solving the problems in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a spinal bone tumor biopsy puncture needle comprises a puncture needle body, wherein the puncture needle body is a hollow tube structure with a through hole in the middle; a plurality of sawteeth are annularly distributed at one end of the puncture needle body and are used for entering a focus through rotation of the sawteeth; and barbs are arranged in the through holes and used for catching focus when the puncture needle body is pulled out.
Optionally, the outer wall of the other end of the puncture needle body is provided with a handle, so that the spinal bone tumor biopsy puncture needle can be conveniently grabbed through the handle, and the spinal bone tumor biopsy puncture needle can be more conveniently and stably controlled.
Optionally, the tips of all the saw teeth extend along the length direction of the puncture needle body, that is, the saw teeth are not arranged in the circumferential direction of the puncture needle body but towards the length direction of the puncture needle body, so that the saw teeth can enter into the focus of the human body more easily.
Optionally, the length of all the sawteeth is shortened in turn along the clockwise direction or the anticlockwise direction of the puncture needle body, and then when the sawteeth enter the focus part of the human body, a structure entering in a spiral mode can be formed, the quantity of the sawteeth in direct contact with the focus part of the human body is reduced, namely, the stress area of the spinal bone tumor biopsy puncture needle in contact with the focus part of the human body is reduced, the resistance of the sawteeth is smaller, the entering mode of the sawteeth is simpler, and the whole body can enter the focus part of the human body more.
Optionally, the face of all the serrations adjacent the axis of the through-hole is bevelled. Alternatively, the longer the length of the saw tooth, the smaller the inclination of the inclined surface thereof. That is to say that the length of sawtooth is shorter more, and the gradient is bigger, can guarantee the stability of sawtooth like this on the sharp basis of guaranteeing the sawtooth, and then make the sawtooth when cutting the focus position, the resistance that receives is littleer as far as possible, just also can make the more light entering human focus position of sawtooth.
For example, the total number of the saw teeth 2 is five, five saw teeth 2 are uniformly and annularly distributed at one end of the puncture needle body 1, and the inclination of one surface of the five saw teeth 2 close to the axis of the through hole 101 is sequentially 1 °, 10 °, 20 °, 30 ° and 40 °, wherein the length of the saw tooth 2 with the inclination of 1 ° is 1.0cm, the length of the saw tooth 2 with the inclination of 10 ° is 0.9cm, the length of the saw tooth 2 with the inclination of 20 ° is 0.8cm, the length of the saw tooth 2 with the inclination of 30 ° is 0.7cm, and the length of the saw tooth 2 with the inclination of 40 ° is 0.6 cm.
Optionally, the circumferencial direction and the length direction of through hole are equallyd divide cloth and are had a plurality of barbs, more accurately say that, all are provided with a plurality of barbs at a plurality of cross sections of pjncture needle body, can be so that the barb is more firm to the snatching of focus, and stability is better.
Optionally, the barb sets up with the internal face acutangular angle of through hole, and the one end of barb is connected with the inner wall of through hole, and the other end of barb extends the setting to the other end of pjncture needle body, when the focus is caught to the barb, can guarantee the stability of snatching for the focus can not be easy breaks away from the barb, and then makes the barb can give an outside power of dragging of focus, and then stable snatchs away from the human body with the focus.
Optionally, the through hole is of a conical hole structure, the inner diameter of the through hole gradually increases from one end of the puncture needle body to the other end of the puncture needle body, so that after a focus enters the through hole, the focus part entering the through hole forms a conical structure along with the fact that the puncture needle body continues to go deep into a focus part of a human body, and when the focus is grabbed, the resistance of the focus breaking away from the through hole is larger, and the focus grabbing of the puncture needle body is easier.
Optionally, an injector is connected to the end of the through hole corresponding to the other end of the puncture needle body. The air in the through hole can be extracted by the syringe, so that the negative pressure state is formed in the through hole, the focus can enter the through hole more easily, and the focus can be grabbed more easily. It should be noted that the syringe is only a distance, and the main function is to suck the air inside the through hole, so that a negative pressure state is formed inside the through hole, and further the focus grasping is more convenient, so that the syringe can be an air extractor capable of sucking the air inside the through hole, such as an air bag or a negative pressure pump. Meanwhile, a connecting structure can be designed at the end part of the through hole corresponding to the other end of the puncture needle body for connecting the puncture needle body and the air extractor, so that a detachable connecting relation is formed, and the puncture needle can be conveniently installed or detached according to actual conditions.
Has the advantages that: the spinal bone tumor biopsy puncture needle realizes the grabbing of the focus by utilizing a similar tubular structure, has a simple structure, can enable the spinal bone tumor biopsy puncture needle to more conveniently and quickly enter the focus position in a human body by utilizing the saw teeth distributed in an annular shape, can enable the focus to enter the through hole to be accurately positioned, and then grabs the focus by utilizing the barbs, so that the focus is easier to be grabbed away from the human body.
