Background
As is known, after a patient clinically diagnoses a tumor primarily, the patient needs to firstly puncture the tumor part through a puncture biopsy needle, take out tumor tissues for pathological examination, determine the specific property of the pathological changes, and then make a specific treatment scheme. However, the traditional tumor puncture needle is mainly divided into 1, different types of high-edge needle points are adopted, and a needle core is rotated to obtain tissues; 2. the syringe consists of a needle head and a piston of the syringe, and when the syringe is used, the piston is pulled to suck tissue fluid; the two types of puncture needles have high probability of not effectively puncturing the tissues in the tumor, thereby bringing the pain of multiple times of puncture and delayed diagnosis and treatment to patients and bringing inconvenience to the work of medical staff.
Disclosure of Invention
The utility model aims at solving the deficiencies of the prior art, providing a simple structure, with low costs, can effectively draw tumor tissue and cell's tumor puncture diagnosis needle, reduce invalid puncture rate, avoid a lot of punctures for the painful bone tumor pjncture needle that the patient brought.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a bone tumor pjncture needle, its characterized in that this pjncture needle includes sleeve, cylinder and nook closing member, the nook closing member outside cover have the cylinder, the outside cover of cylinder has the sleeve, the lower extreme inner wall of cylinder on be equipped with internal screw thread form spiral blade, the lower extreme of spiral blade stretch out the cylinder part, the lower extreme of nook closing member establish to sharp form, extract the nook closing member after penetrating the tumour tissue through sleeve, cylinder and nook closing member three are integrative, rethread rotates the cylinder and makes the cylinder remove and cut tumour tissue towards the below under the effect of internal screw thread form spiral blade, makes tumour tissue take out after staying cylinder lower extreme inside.
Telescopic rear end be equipped with outer handle, the cylinder rear end is equipped with well handle, the nook closing member rear end is equipped with interior handle, the upper end of outer handle be equipped with well handle and accomodate the groove, well handle accomodate the tank bottom in groove be equipped with the outer through-hole of sleeve intercommunication, the upper end of well handle be equipped with interior handle and accomodate the groove, the tank bottom that the groove was accomodate to interior handle is equipped with the interior through-hole that is linked together with the cylinder, interior through-hole supplies the nook closing member to insert.
The height of the lower end of the spiral blade extending out of the needle cylinder is 0.2-1mm, so that the needle cylinder can be conveniently screwed downwards to easily cut tumor tissues.
The height of the internal thread-shaped spiral blade at the lower end of the needle cylinder is 3-5cm, so that the sampling length is limited.
The length of the needle cylinder is larger than the length of the sleeve, the difference between the length of the needle cylinder and the length of the sleeve is 3-5cm, and the needle cylinder can conveniently extend into tumor tissues from the lower part.
The width of the internal thread-shaped spiral blade at the lower end of the needle cylinder is 1mm, the thread pitch is 2-4mm, and the cut tumor tissues can be effectively extruded and rotated into the needle cylinder.
By adopting the above structure, the utility model, have simple structure, with low costs, can effectively draw the tumour puncture diagnosis needle of tumour tissue and cell, reduce invalid puncture rate, avoid advantages such as the misery that many times of punctures brought for the patient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the attached drawing, the bone tumor puncture needle is characterized by comprising a sleeve 1, a needle cylinder 2 and a needle core 3, wherein the needle cylinder 2 is sleeved outside the needle core 3, the sleeve 1 is sleeved outside the needle cylinder 2, an internal thread-shaped spiral blade 4 is arranged on the inner wall of the lower end of the needle cylinder 2, the lower end of the spiral blade 4 extends out of the needle cylinder 2, the lower end of the needle core 3 is pointed, the needle core 3 is extracted after the sleeve 1, the needle cylinder 2 and the needle core 3 are integrally punctured into tumor tissue, and then the needle cylinder 2 moves downwards under the action of the internal thread-shaped spiral blade 4 and cuts the tumor tissue by rotating the needle cylinder 2, so that the tumor tissue is left inside the lower end of the needle cylinder 2 and then is extracted.
Further, sleeve 1's rear end be equipped with outer handle 5, 2 rear ends of cylinder are equipped with well handle 6, and 3 rear ends of nook closing member are equipped with interior handle 7, the upper end of outer handle 5 be equipped with well handle and accomodate groove 8, well handle accomodate the tank bottom of groove 8 be equipped with the outer through-hole of sleeve 1 intercommunication, the upper end of well handle 6 be equipped with interior handle and accomodate groove 9, the tank bottom that interior handle accomodates groove 9 is equipped with the interior through-hole that is linked together with cylinder 2, interior through-hole supplies nook closing member 3 to insert.
Furthermore, the height of the lower end of the spiral blade 4 extending out of the needle cylinder 2 is 0.2-1mm, so that the needle cylinder 2 can be conveniently screwed downwards, and tumor tissues can be easily cut.
Further, the height of the internal thread-shaped spiral blade 4 at the lower end of the needle cylinder 2 is 3-5cm, so that the sampling length is limited.
Furthermore, the length of the needle cylinder 2 is larger than that of the sleeve 1, and the difference between the length of the needle cylinder 2 and the length of the sleeve 1 is 3-5cm, so that the needle cylinder 2 can extend into tumor tissues downwards.
