Description
Technical Field
The utility model relates to the field of flushing parts, in particular to a puncture needle flushing part.
Background
Under the guidance of B ultrasonic, the prostate puncture needle is used for biopsy and diagnosis of prostate cancer, and is widely applied in clinic at present. According to the tumor site, 10-15 needle punctures are performed, and each site of the prostate is taken. Each needle can take down the prostate tissue penetrated by the puncture needle, and the collection is inconvenient because the sample is tiny; therefore, the puncture needle is directly washed in the bottled formalin bottle at present, so that the collection of specimens is facilitated. However, if the puncture needle tip is dipped with formalin liquid and then is not thoroughly flushed, trace formalin solution can enter the puncture part of a patient along with the needle, and a certain amount of solution can enter local tissues of the patient after multiple punctures, so that iatrogenic injury or hidden danger of examination is caused to the patient.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to solve the technical problems described in the background art, the utility model provides a puncture needle flushing piece. The needle body is placed in the needle body accommodating pipe, and the flushing liquid is sent into the needle body accommodating pipe through the water receiving pipe, so that the needle body in the needle body accommodating pipe is flushed, and the tiny specimen on the needle body is flushed out and collected. The needle body can be prevented from contacting formalin, and further iatrogenic injury to a patient caused by repeated puncture can be avoided.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a puncture needle washes piece, includes needle body holding pipe, water receiving pipe, sealing block, connecting piece, be connected with the water receiving pipe that is used for the input flushing fluid on the body of needle body holding pipe, the entrance that the needle body held the pipe is equipped with the sealing block that is used for preventing that the flushing fluid from flowing into the connecting piece and is used for the connecting piece on the cylinder with washing the piece.
Specifically, the connecting piece comprises a sleeve body and a rubber ring, wherein an opening at one end of the sleeve body is fixed at the inlet of the needle body accommodating tube, and the rubber ring is fixed at the edge of the opening at the other end of the sleeve body.
Specifically, the sleeve body is a film sleeve.
Specifically, a conical hole is formed in the sealing block.
Specifically, a sealing ring is arranged at the opening of the conical hole.
The beneficial effects of the utility model are as follows: the utility model provides a puncture needle flushing piece. The needle body is placed in the needle body accommodating pipe, and the flushing liquid is sent into the needle body accommodating pipe through the water receiving pipe, so that the needle body in the needle body accommodating pipe is flushed, and the tiny specimen on the needle body is flushed out and collected. The needle body can be prevented from contacting formalin, and further iatrogenic injury to a patient caused by repeated puncture can be avoided.

Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
FIG. 1 is a schematic diagram of the structure of the present utility model; fig. 2 is a cross-sectional view of a sealing block of the present utility model.
As shown in figure 1, the puncture needle flushing piece comprises a needle body accommodating pipe 1, a water receiving pipe 2, a sealing block 3 and a connecting piece 4, wherein the pipe body of the needle body accommodating pipe 1 is connected with the water receiving pipe 2 for inputting flushing liquid, and the inlet of the needle body accommodating pipe 1 is provided with the sealing block 3 for preventing the flushing liquid from flowing into the connecting piece 4 and the connecting piece 4 for connecting the flushing piece on a needle cylinder.
The connecting piece 4 consists of a sleeve body 41 and a rubber ring 42, wherein one end opening of the sleeve body 41 is fixed at the inlet of the needle body accommodating tube 1, and the rubber ring 42 is fixed at the edge of the other end opening of the sleeve body 41.
The sleeve body 41 is a film sleeve.
As shown in fig. 2, a tapered hole 5 is provided in the sealing block 3.
The opening of the conical hole 5 is provided with a sealing ring 6. The sealing ring 6 can prevent water from flowing out from the inlet of the needle accommodating tube 1 when water enters the needle accommodating tube 1.
The application mode is as follows: after the puncture needle samples, the needle body is inserted in the inlet of the needle body accommodating tube 1, and passes through the connecting piece 4 and the sealing block 3 until the connector of the needle cylinder and the needle body is attached to the sealing ring 6 of the sealing block 3, and the needle body is positioned in the needle body accommodating tube 1. While the rubber ring 42 is tightened against the barrel. Finally, the flushing liquid is input into the needle accommodating pipe 1 through the water receiving pipe 2, the needle in the needle accommodating pipe 1 is flushed, and the flushed specimen is collected.
