Abstract
The utility model discloses a tumour puncture sampling needle which comprises a puncture needle core formed by a needle core and a needle base, an inclined inverted hook is arranged at the head part of the needle core, a sleeve needle is sheathed at the outer part of the puncture needle core, the sleeve needle comprises a sleeve needle head and a sleeve needle seat, the front end of the sleeve needle head is in a diagonal plane which is the same as that of the front end of the needle core, and the length of the needle core is larger than that of the sleeve needle head. When the tumour puncture sampling needle carries out histological examination on a patient, the puncture needle core and the sleeve needle can be simultaneously punctured under skin to the surface of a lump and are pushed into a little depth, then, the puncture needle core is continuously punctured into the center of the lump, and is rotated by a circle to take out a block of tissue by the inverted hook on the head part of the needle core, and the inverted hook on the needle core is retreated into the sleeve needle, therefore, the needle core and the sleeve needle are simultaneously pulled. The tumour puncture sampling needle disclosed by the utility model is simple and convenient, and safe when carrying out histological examination on the patient, so that operation pains of the patient can be avoided. The tumour puncture sampling needle disclosed by the utility model can be widely applied in clinics.
Description
Technical field this utility model belongs to technical field of medical instruments, relates to a kind of tumor puncture sampling probe that histological examination is carried out in the tumor puncture that is used for.
Background technology is present, and cytolgical examination and histological examination method are generally adopted in clinical inspection to tumor.Cytolgical examination is to do inspection with the cell that fine needle is drawn affected area, and prior art generally adopts entry needle, has in the operation that negative pressure is big, pin hole stops up easily, draws that thing is less, the depth is difficult for defectives such as grasp, and entry needle can't be done histological examination.When doing histological examination, need cut the fritter tumor tissues by operation and check, bring great misery to the patient.
The summary of the invention the purpose of this utility model is to solve prior art to have the technical problem that sampling is difficult, the patient suffering is big, provides a kind of tumor puncture sampling probe that carries out histological examination, to overcome the deficiencies in the prior art.
To achieve these goals, this utility model tumor puncture sampling probe comprises the puncture nook closing member that is made of nook closing member and needle stand, and its main points are: the head at nook closing member is provided with an oblique barb, the outside sheathed trocar of puncture nook closing member, the trocar is made of sleeve pipe syringe needle and sleeve pipe needle stand; Described sleeve pipe syringe needle front end is the oblique section identical with the nook closing member front end; Described nook closing member length is greater than the length of sleeve pipe syringe needle.
When this utility model is done histological examination to patient, puncture nook closing member and the trocar together can be thrust subcutaneous surperficial and advance a little to lump, the nook closing member that will puncture then continues to thrust the lump center, rely on the barb of nook closing member head to take off a block organization rotation of puncture nook closing member, the barb on the nook closing member is retreated in the trocar together extract again.When this utility model is done histological examination, not only easy but also safety, the hardship of having exempted patient's operation can be widely used in clinical.
Appended drawings is this utility model structural representation.
The specific embodiment is with reference to accompanying drawing, this utility model comprises the puncture nook closing member that is made of nook closing member 1 and needle stand 2, head at nook closing member 1 has an oblique barb 3, be with a trocar in the outside of nook closing member 1, the trocar is made of sleeve pipe syringe needle 4 and sleeve pipe needle stand 6, sleeve pipe syringe needle 4 front ends are the oblique section 8,7 identical with nook closing member 1 front end, and nook closing member 1 length is greater than the length of sleeve pipe syringe needle 4.During use, earlier do routine disinfection to the site of puncture, with 0.5% benefit card 2-4ml local anaesthesia,, nook closing member 1 and sleeve pipe syringe needle 4 are together thrust subcutaneous to the lump surface and advance a little with the fixing lump of left index finger and thumb, then nook closing member 1 is continued to thrust the lump center, nook closing member 1 is rotated a circle, rely on the barb 3 of nook closing member 1 head to take off a little block organization, nook closing member 1 is retreated in the trocar lumen 5 together extract again, take off piece of tissue in barb 3, it is to be checked to put into the formal Specimen bottle.The tissue of obtaining can not push, and can not damage trunk, presses slightly puncture place 2-3 minute after pulling out pin, in case hematoma.
