Description

A device and method for collecting and storing specimens for prostate biopsy

technical field

The invention relates to a new type of medical equipment, in particular to a device and method for collecting and storing specimens for prostate biopsy.

Background technique

With the development of my country's economy and society, the awareness of national health care and health check-ups are increasing, and prostate cancer screening is gradually becoming popular. More and more patients need to undergo prostate biopsy. According to the patient's age, physical fitness, prostate size, PSA level, tumor invasion range and other indicators, the current number of puncture needles is mostly 8 or 13. Due to the lack of standardized puncture and collection equipment, every time a prostate biopsy is performed, the operator needs to temporarily find a large number of empty bottles with different styles and contents, wash them and then fill them with 10% formalin as a specimen fixation It is time-consuming and laborious, and the fixing solution volatilizes during the production process, polluting the environment and bringing potential hazards to the health of operators. The prostate specimen obtained during the puncture will be more tightly adhered to the puncture needle, and it is difficult to directly immerse it in the fixative solution to make the specimen fall off by itself and enter the specimen bottle. If the puncture needle is attached to the mouth of the bottle and pulled back, use the edge of the bottle mouth to block and separate the specimen and the puncture needle. The specimen often adheres to the mouth of the bottle, and it is necessary to use additional fine needles or auxiliary instruments to pick up the specimen and put it into the fixative middle. If the specimen is dropped from the bottle mouth by inversion and vibration, the specimen adhered to the bottle mouth will affect the closure of the bottle cap, and the fixative will overflow from the gap of some bottle caps that are not tightly closed during the process of inversion and vibration. Therefore, the self-made specimen bottle has the inconvenience that the specimen attached to the puncture needle is difficult to come off smoothly and enter the fixative in the bottle. The common practice in clinical work is at present, scratches the puncture needle attached to the specimen on the hands to make the specimen fall off in the palm of the hand, and then picks up the specimen with a fine needle and places it in the specimen bottle. The steps of this method are cumbersome, and it is easy to accidentally injure people's hands, resulting in iatrogenic injury.

Contents of the invention

Technical problem: The technical problem to be solved by the present invention is to provide a device and method for collecting and storing specimens for prostate biopsy with strong stripping ability. Among the fixed solutions in the bottle, it has the advantages of simple structure, low cost and convenient use.

Technical scheme: in order to solve the above technical problems, the technical scheme adopted in the present invention is:

A sample collection and storage device for prostate puncture biopsy according to the present invention comprises a sealed bottle, a detachable sealed bottle cap and a bottle number are arranged on the top of the bottle, a push rod is arranged on the sealed bottle cap, and There is a sealing sheet in the bottle, and the lower space of the sealed bottle formed by the sealing sheet is the specimen storage chamber, and the fixative is filled in the specimen storage chamber, and an arc-shaped indentation is arranged on the sealing sheet, when the arc-shaped indentation After the inner sealing sheet area is subjected to top pressure, arc-shaped indentation cracks are generated on the sealing sheet and form a door sheet.

A method for collecting and storing specimens for prostate biopsy according to the present invention comprises the following steps:

Step 1 Take a sealed bottle corresponding to the bottle number and there is a push rod on the sealed bottle cap. There is a sealing sheet inside the sealed bottle. The lower space of the sealed bottle separated by the sealing sheet is the specimen storage chamber. filled with fixative,

Step 2 Unscrew the sealing bottle cap, press the sealing sheet with the ejector pin, so that the sealing sheet produces arc-shaped indentation cracks and forms a door that opens into the specimen storage chamber,

Step 3 Insert the puncture needle attached with the specimen from the door and into the specimen storage chamber, and then use the specimen attached to the puncture needle to drive and close the door. As the door closes, the gap between the door and the sealing piece The gap gradually decreases, and the specimen is immediately held together by the door and the sealing plate, and then the puncture needle is pulled out again, and the specimen attached to the puncture needle falls off from the puncture needle, falls into the specimen storage chamber, and is immersed in the fixative solution , and finally cover the airtight bottle cap and tighten it.

Compared with prior art, the present invention has following advantage:

In the present invention, an arc-shaped indentation is set on the sealing sheet, so that after the sealing sheet area in the arc-shaped indentation is pressed by the ejector rod, an arc-shaped indentation crack is formed on the sealing sheet and a door sheet is opened into the specimen storage cavity. The puncture needle attached with the specimen is inserted from the door and enters the specimen storage chamber, and the specimen attached to the puncture needle is used to drive and close the door. As the door is closed, the gap between the door and the sealing piece gradually decreases , the specimen is immediately resisted by the door piece and the sealing piece together, and is stuck in the gap between the door piece and the sealing piece (see Figure 3), and then the puncture needle is pulled out again, and the specimen attached to the puncture needle is released on the door. Under the joint action of the sealing sheet and the sealing sheet, it falls off from the puncture needle, falls into the specimen storage chamber, and is immersed in the fixative solution. It can be seen that the whole process of stripping the specimen from the puncture needle is in a relatively closed environment in the sealed bottle. The peeling of the specimen is completed directly by using the inner door and sealing sheet of the bottle, avoiding operations such as scratching and peeling on the outside of the sealed bottle, so that the sample is free from contamination during the peeling process and avoids accidental injuries caused by the puncture needle. iatrogenic injury, at the same time, the peeling of the sample by using the above-mentioned joint action of the door sheet and the sealing sheet greatly improves the peeling force of the sample, and even the sample with a strong binding force can be successfully peeled off from the puncture needle by the present invention down.

The invention has simple structure, low cost and convenient use. The specimen collection and storage device for prostate puncture biopsy of the present invention comprises a sealed bottle, a sealed bottle cap and a sealed sheet. The entire unit is made of plastic for low cost. When in use, select the device with the number of the bottle body corresponding to the sample number, push away the arc-shaped indentation of the sealing sheet through the ejector rod in the center of the bottle cap, generate an arc-shaped indentation crack on the sealing sheet and form a door sheet, and then use the attached The specimen on the puncture needle goes to close the door, and as the door closes, the gap between the door and the sealing sheet gradually decreases, and the specimen is immediately resisted by the door and the sealing sheet, and then the puncture needle is pulled out and attached The specimen on the puncture needle falls off from the puncture needle, falls into the specimen storage cavity, and is immersed in the fixing solution, which is simple and convenient to use. If the specimen sticks to the door or seal when it comes off the puncture needle, shake the sealed bottle to allow the fixative to wash over the specimen and cause it to fall off and fall into the fixative. At the same time, the collection bottle of the present invention can be made into sets of 8 and 13, which can be selected according to the patient's age, constitution, prostate size, PSA level, tumor invasion range, etc., to meet the needs of patients with different conditions, avoid waste, and facilitate popularization and application.
