Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pathological tissue collection bottle used for puncture needle pathology. Background Technology

[0002] Pathological puncture needles are medical devices used to obtain human tissue or cell samples. They are mainly divided into two categories: core needles and fine needles. The core function of pathological puncture needles is to assist doctors in clarifying the nature of lesions through minimally invasive procedures.

[0003] After the pathological tissue specimen is collected using a pathological puncture needle, the pathological tissue specimen adhering to the tip of the needle needs to be removed and collected using a collection bottle.

[0004] It should be noted that the Chinese utility model patent with patent number ZL201820465450.1 and patent name "A Novel Puncture Tissue Specimen Collection Bottle" substantially discloses a collection bottle device for collecting pathological tissue specimens from a pathological puncture needle. Specifically, this novel puncture tissue specimen collection bottle discloses the following technical solution: A novel puncture tissue specimen collection bottle includes a specimen bottle, a cap, an inner core, and a brushing device. The specimen bottle is used to hold the specimen on the puncture needle. The cap is detachably and fixedly connected to the mouth of the specimen bottle. The inner core has a tubular structure with openings at both ends, with one end fixedly connected to the cap and the other end sealed to the bottom of the specimen bottle. The cap has a through hole corresponding to the opening of the inner core. The brushing device is located inside the inner core and is used to brush off the specimen from the puncture needle.

[0005] During the collection of puncture tissue specimens using the aforementioned novel puncture tissue specimen collection bottle, formaldehyde solution or other fixative is injected into the inner core. Only a small amount of tissue fixative is needed to immerse the tissue specimen on the puncture needle, reducing the adhesion between the tissue specimen and the puncture needle and making it easier to detach. A brushing device set in the inner core is used to assist in brushing off the tissue specimen on the puncture needle. The bottle cap is separated from the specimen bottle so that the pathological tissue specimen in the inner core falls into the specimen bottle.

[0006] It should be noted that the aforementioned new type of puncture tissue specimen collection bottle still has the following defects, specifically: Defect 1: When detaching the pathological tissue specimen from the pathological puncture needle, it is necessary to first inject the tissue fixative into the core, and then insert the pathological puncture needle with the pathological tissue specimen attached into the core containing the tissue fixative. During this process, the tissue fixative in the core can easily overflow, which increases the wiping and cleaning process and makes it less convenient to use. Defect 2: When collecting pathological tissue specimens from the pathological puncture needle using this new type of puncture tissue specimen collection bottle, the bottle cap must first be kept closed to ensure the airtightness between the inner core and the bottom of the bottle. Then, the bottle cap needs to be opened to allow the pathological tissue specimen in the inner core to fall into the specimen bottle. Finally, the bottle cap needs to be closed to achieve the in-hospital transfer of the pathological tissue specimen. That is, the entire operation involves multiple bottle cap closing operations, which is relatively complicated and inconvenient to use. Utility Model Content

[0007] The purpose of this invention is to provide a pathological tissue collection bottle for puncture needle pathology, which addresses the shortcomings of existing technologies. This pathological tissue collection bottle for puncture needle pathology has a novel structural design and is easy to use.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0009] A pathological tissue collection bottle for use in puncture needle pathology includes a bottle body and a bottle cap. The bottle body has an upward-opening collection chamber inside, and the bottle cap is detachably attached to the upper end of the bottle body. The bottle cap is equipped with a specimen scraper that extends vertically downwards and into the collection chamber. The specimen scraper has a flat, sheet-like structure. The specimen scraper has a bottom edge, a first vertical edge, and a second vertical edge that is spaced apart from the first vertical edge. The lower end of the front of the specimen scraper has a specimen scraping groove that opens toward the first vertical edge. The specimen scraping groove is a slanted groove structure, and the thickness value of the specimen scraper at the corresponding specimen scraping groove position gradually decreases along the direction close to the first vertical edge. The specimen scraper has a guide flange extending along the bottom edge and the second vertical edge on the front side, and the guide flange protrudes from the front side of the specimen scraper.

[0010] The bottom edge of the specimen scraper and the second vertical edge are transitioned by a rounded corner, and the guide flange is aligned with the specimen scraping groove in an arc shape.

[0011] The specimen scraper has a wedge-shaped reinforcing rib on its back side, and the reinforcing rib is an integral structure with the specimen scraper.

[0012] The bottle body has an external thread on its outer circumferential surface at the upper end, and the bottle cap has an internal thread on its inner circumferential surface. The internal thread of the bottle cap is screwed into the external thread of the bottle body.

[0013] The bottle body is a transparent component.

[0014] The bottle cap has several anti-slip grooves arranged at intervals along its circumference on its outer circumference.

[0015] The specimen scraper and the bottle cap are injection molded into a single structure.

[0016] The bottle cap has a downward-facing alignment groove corresponding to the specimen scraper. The upper end of the specimen scraper is inserted into the alignment groove of the bottle cap, and the specimen scraper is glued or fused to the bottle cap.

[0017] Compared with existing technologies, this invention has the following advantages: Specifically, when collecting pathological tissue specimens from a biopsy needle using this invention, medical personnel hold the operating bottle cap and scrape off the pathological tissue specimen adhering to the biopsy needle using the specimen scraper on the cap. The specimen scraping groove and guide flange on the specimen scraper allow the pathological tissue specimen to adhere to the scraper. After scraping off the pathological tissue specimen, the bottle cap is closed, and the specimen scraper is inserted into the collection chamber of the bottle. Compared with existing technologies, the pathological tissue collection bottle of this invention for biopsy needles has the advantages of novel structural design and ease of use.

Detailed Implementation

[0023] The present invention will now be described in conjunction with specific embodiments.

[0024] Example 1, as Figures 1 to 3 As shown, a pathological tissue collection bottle for puncture needle pathology includes a bottle body 1 and a bottle cap 2. The bottle body 1 has an upward-opening collection chamber 11 formed inside, and the bottle cap 2 is detachably installed at the upper end of the bottle body 1.

[0025] It should be explained that the bottle cap 2 can be connected to the bottle body 1 by screwing. Specifically, the outer circumferential surface of the upper end of the bottle body 1 is provided with an external thread 12, and the inner circumferential surface of the bottle cap 2 is provided with an internal thread 21. The internal thread 21 of the bottle cap 2 is screwed to the external thread 12 of the bottle body 1. Of course, the above screwing method does not constitute a limitation on this embodiment, that is, the bottle cap 2 in this embodiment can also be connected to the bottle body 1 by twisting or snapping.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the bottle cap 2 is equipped with a specimen scraper 3 that extends vertically downward and into the collection chamber 11. The specimen scraper 3 has a flat sheet structure.

[0027] It should be explained that the specimen scraper 3 and the bottle cap 2 are injection molded into an integral structure; or, the bottle cap 2 has a downward-facing alignment groove corresponding to the specimen scraper 3, the upper end of the specimen scraper 3 is inserted into the alignment groove of the bottle cap 2, and the specimen scraper 3 is glued or ultrasonically welded to the bottle cap 2.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the edge of the specimen scraper 3 includes a bottom edge 311, a first vertical edge 312, and a second vertical edge 313 arranged opposite to the first vertical edge 312 at intervals. The lower end of the front side of the specimen scraper 3 is provided with a specimen scraping groove 32 that opens toward the first vertical edge 312. The specimen scraping groove 32 is a slanted groove structure, and the thickness value of the specimen scraper 3 at the position corresponding to the specimen scraping groove 32 gradually decreases along the direction close to the first vertical edge 312.

[0029] In addition, the front side of the specimen scraper 3 is provided with a guide flange 33 extending along the bottom edge 311 and the second vertical edge 313. The guide flange 33 protrudes from the front side of the specimen scraper 3 and the guide flange 33 is an integral structure with the specimen scraper 3.

[0030] In the process of collecting pathological tissue specimens using the pathological tissue collection bottle applied to puncture needles in this embodiment, the bottle cap 2 is first removed from the upper end of the bottle body 1. Then, the medical staff holds the pathological puncture needle with the left hand, making the needle tip face forward, and the long strip of pathological tissue specimen adheres to the front end of the pathological puncture needle. The medical staff then takes the bottle cap 2 with the right hand, aligns the specimen scraping groove 32 of the specimen scraper 3 with the pathological tissue specimen of the pathological puncture needle, and scrapes the specimen scraper 3 along the needle tail towards the needle tip, so that the pathological tissue specimen passes through the specimen scraping groove 32, and finally the pathological tissue specimen adhering to the pathological puncture needle is scraped off by the specimen scraper 3. During this process, the pathological tissue specimen adheres to the specimen scraper 3. Finally, the specimen scraper 3 with the pathological tissue specimen attached is inserted into the placement chamber of the bottle body 1 and the bottle cap 2 is closed to complete the collection of pathological tissue specimens using the collection bottle.

[0031] It should be emphasized that the guide flange 33 in this embodiment has the following functions: 1. When medical personnel scrape the specimen scraper 3 and allow the pathological tissue specimen to pass through the specimen scraping groove 32, the guide flange 33 can guide the long strip of pathological tissue specimen to turn, so that the long strip of pathological tissue specimen can be stably attached to the front of the specimen scraper 3, so as to prevent the pathological tissue specimen from slipping off from the second vertical edge 313 when scraping; 2. The guide flange 33 can play a blocking role. When the specimen scraper 3 with the long strip of pathological tissue specimen attached is inserted into the collection chamber 11 of the bottle 1, the guide flange 33 can prevent the pathological tissue specimen attached to the specimen scraper 3 from slipping off and falling off.

[0032] It should be further emphasized that the specimen scraping groove 32 in this embodiment is a slanted groove structure, and the thinnest part of the specimen scraper 3 is the specimen scraping groove 32 at the first vertical edge 312. This structural design makes it easier for the specimen scraper 3 to scrape the pathological tissue specimen off the pathological puncture needle.

[0033] It should be noted that when it is necessary to remove the pathological tissue specimen from the collection bottle, since the pathological tissue is attached to the specimen scraper 3, medical staff only need to open the bottle cap 2 and pull the specimen scraper 3 out of the collection chamber 11 of the bottle body. That is, there is no need to use tweezers to pick up the pathological tissue specimen from the collection chamber 11, making the operation very convenient.

[0034] In summary, since this embodiment does not involve immersion in tissue fixation fluid or repeated cap 2 closing operations, the pathological tissue collection bottle used for puncture needle pathology in this embodiment has the advantages of novel structural design and good ease of use compared to the prior art.

[0035] Example 2, as Figure 2 and Figure 3As shown, the difference between this embodiment 2 and embodiment 1 is that the bottom edge 311 of the specimen scraper 3 and the second vertical edge 313 are transitioned by rounded corners, and the position of the guide flange 33 aligned with the specimen scraping groove 32 is an arc-shaped part 331.

[0036] The arc portion 331 located on the guide flange 33 can effectively ensure the stable and accurate turning of the long strip-shaped pathological tissue specimen.

[0037] Example 3, as Figure 3 As shown, the difference between this embodiment 3 and embodiment 1 is that the back of the specimen scraper 3 is provided with a wedge-shaped reinforcing rib 34, and the reinforcing rib 34 and the specimen scraper 3 are an integral structure.

[0038] The reinforcing rib 34 in this embodiment 3 can effectively enhance the structural strength of the specimen scraper 3.

[0039] Example 4, as Figure 2 and Figure 3 As shown, the difference between this embodiment four and embodiment one is that the bottle body 1 is a transparent part.

[0040] As for bottle 1 in this embodiment 4, since it is a transparent structure, medical staff can easily and intuitively view the storage status of the disease tissue specimens inside the collection bottle.

[0041] Example 5, as Figures 1 to 3 As shown, the difference between this fifth embodiment and the first embodiment is that the outer circumferential surface of the bottle cap 2 is provided with a plurality of anti-slip grooves 22 arranged sequentially and at intervals along the circumference of the bottle cap 2.

[0042] As for the anti-slip groove 22 in this embodiment, it can facilitate medical staff to rotate the bottle cap 2 to avoid slipping when rotating the bottle cap 2.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
