Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a cell brush pathological specimen bottle. Background Technique
[0002] A cell brush is a medical device suitable for brushing tissue samples of the respiratory tract and digestive tract under endoscopy, and is a disposable medical device. Endoscopic cell brushing is a method of obtaining diseased cells by repeatedly brushing the surface of a lesion with a cell brush under direct vision of an endoscope. It can brush mucosal cells of the lesion over a large area, especially cells on ulcer surfaces, bleeding sites and biopsy wounds, and complements biopsy pathology examinations, reducing the missed diagnosis rate and having great value for disease diagnosis, especially for the initial screening of tumors.
[0003] After the cell brush extracts pathological tissue, it needs to be put into a pathological bottle and sent to the pathology department. Currently, the most commonly used method in clinical practice is to cut off the brush head with scissors. However, when different patients use the same pair of scissors, it is easy to cause cross-contamination. With the development of high-tech detection technologies such as gene detection, the required sample volume for detection is getting smaller and smaller, and it is even possible to accurately determine the gene expression profile within a single cell. During the process of using the same pair of scissors to cut off the brush heads of cell brushes from different patients, even if there is contamination of a single cell, it may cause misdiagnosis for the patient. Especially for patients who use cell brushes to obtain pathology, most of them are suspected of having tumors, and the purpose of obtaining pathology is to confirm whether they have malignant tumors, determine the pathological type of the tumor and the gene expression profile. In this case, if misdiagnosis occurs, it will cause great confusion to clinicians' diagnosis and also bring great harm to the patients.
[0004] There may already be technical solutions in the prior art to solve the above technical problems. In view of this, this case wants to provide an alternative or substitute technical solution. Content of the Utility Model
[0005] In view of the deficiencies of the prior art, the utility model provides a cell brush pathological specimen bottle, which solves the technical problem of cross-contamination of pathological tissues of different patients during the existing pathological recycling process.

An external thread is provided on the mouth of the storage bottle, and a bottle cap is screwed onto the mouth of the storage bottle. An internal thread matching the external thread is provided inside the bottle cap. A scissor head fixing ring is assembled on the side wall of the storage bottle. A scissor head fixing rod is inserted into the scissor head fixing ring. A disposable scissor head is clamped on the scissor head fixing rod. A scissor head insertion rod is assembled on the disposable scissor head, and a reusable scissor handle is inserted on the scissor head insertion rod.
[0007] Preferably, a push button is movably assembled in the card slot of one connecting arm of the reusable scissors.
[0008] Preferably, a magnet block is assembled in the card slot of the other connecting arm of the reusable scissors.

[0022] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment:
[0024] Refer to Figures 1-4 , it is realized that the cell brush head is cut off by a disposable scissor head to avoid cross-contamination. The reusable scissor handle 9 is reusable, and each patient only needs to replace a disposable scissor head 7, with low usage cost and easy to promote. The specific working principle is as follows.
[0025] When in use, check that the push button 10 is in the retracted state, insert the scissor head insert rod 8 into the jack of the reusable scissor handle 9, so that the disposable scissor head 7 is installed on the reusable scissor handle 9. A magnet block 11 is provided in the jack of the reusable scissor handle 9, which has an attracting effect on the scissor head insert rod 8 made of metal iron material, making the insertion more convenient and firm.
[0026] Open the storage bottle 1, place the bottle cap 3 upside down with the opening facing upwards in a clean area, and use the silicone suction cup 14 to suck the storage bottle 1 onto the table to prevent the storage bottle 1 from sliding or tipping during the operation, resulting in the spillage of formalin solution or specimens.
[0027] Medical staff hold the reusable scissor handle 9 in their right hand and insert the scissor head fixing rod 6 into the scissor head fixing ring 5. Hold the cell brush after pathology with the left hand, insert the cell brush head into the storage bottle 1 through the gap between the anti-slip grooves 13 between the two scissor blades. Note that the cell brush is located within the anti-slip grooves 13, and cooperate with the right hand to cut off the cell brush head so that the brush head falls into the storage bottle 1. Check the brush head and soak it in the formalin solution, and throw the remaining cell brush into the medical waste bin with the left hand. The cell brush is made of steel wire braid, and it is easy to slide when cutting, especially after use when the cell brush is attached with the patient's mucus, and it is more likely to slip off when cutting. The anti-slip grooves 13 are provided to prevent the cell brush from sliding when cutting.
[0028] Vacate the left hand to hold the scissor head fixing rod 6 and remove it from the scissor head fixing ring 5. Push the push knob 10 forward with the right hand, and cooperate with both hands to separate the disposable scissor head 7 from the reusable scissor handle 9. There is a magnet block 11 in the insertion hole of the reusable scissor handle 9, which has an attracting effect on the scissor head. Therefore, there is a certain resistance when separating the disposable scissor head 7 from the reusable scissor handle 9. The push knob 10 is set to push out the disposable scissor head 7, making it easier to remove the scissor head. At the same time, it can avoid splashing the patient's body fluid on the scissor head due to excessive force when pulling out the disposable scissor head 7, resulting in environmental pollution.
[0029] Throw the disposable scissor head 7 into the sharp container, and retract the push knob 10 to the recycling state.
[0030] Retrieve the bottle cap 3 and tighten it to seal. Affix a label and send it to the pathology department.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
