Abstract
The utility model discloses a sampler for a tumor tissue examination, which comprises a puncture needle core composed of a needle core and a needle seat. The utility model has the point that the head part of the needle core is provided with a sloping barb, the outer part of the puncture needle core is sheathed with a trocar and the trocar is composed of a trocar head and a trocar seat. When a patient does histological examination by the utility model, the puncture needle core and the trocar can penetrate a skin together to the surface of a tumor and is propelled a little and then the puncture needle core continues penetrating the center of the tumor. The puncture needle core rotates a circle, a piece of tissue is disassembled through the barb at the head part of the needle core and the barb on the needle core is withdrawn to the inner side of the trocar and is drawn together. When the sampler of the utility model does the histological examination, the utility model is simple and convenient and safe, avoids the pain of an operation for the patient and can be widely used for clinic.
Description
Technical field this utility model belongs to technical field of medical instruments, relates to a kind of tumor tissues censored sample device that histological examination is carried out in tumor puncture and lymph node and soft tissue neoplasms 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 provides a kind of tumor tissues censored sample device that carries out histological examination, to overcome the deficiencies in the prior art.
To achieve these goals, this utility model tumor tissues censored sample device 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.
Said sleeve pipe syringe needle front end is the oblique section identical with the nook closing member front end.
Said 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, the nook closing member that will puncture rotates a circle, rely on the barb of nook closing member head to take off a block organization, the barb on the nook closing member is retreated in the trocar together extract again.When this utility model sampler is done histological examination, not only easy but also safety, the hardship of having exempted patient's operation can be widely used in clinical.
Description of drawings Fig. 1 is a puncture needle cored structure sketch map of the present utility model;
Fig. 2 is a trocar design sketch map of the present utility model.
Among the figure: 1, nook closing member 2, needle stand 3, barb 4, sleeve pipe syringe needle 5, trocar lumen 6, sleeve pipe needle stand 7,8, oblique section
The specific embodiment is with reference to Fig. 1, Fig. 2, 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 4 in the outside of nook closing member 1, the trocar 4 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.
