[0002] The content of this part only provides background information related to the utility model, which may not constitute prior art.

[0003] During the pathological specimen sampling in endoscopic examination (also known as endoscopy), it is an important basis for clinical digestive doctors to judge benign and malignant tumors and chronic inflammation of the gastrointestinal tract. The test results directly affect the diagnosis, treatment and prognosis analysis of diseases. Rapid collection of pathological specimens during endoscopy can effectively shorten the time of endoscopy, reduce the pain of patients and ensure the safety of patients.

[0004] During the endoscopic examination, the traditional method for collecting pathological specimens is to stick the removed pathological specimens one by one on filter paper. If there are pathological specimens that require multiple-site biopsy and separate bottle submission for inspection, especially for patients with inflammatory gastrointestinal diseases who may need to obtain pathological specimens from multiple sites, at this time, the patient needs to wait for the nurse to first put the pathological specimen into a bottle after each site is taken, then prepare the next filter paper, and then take the pathological specimen from the next site.

[0005] The following defects exist in the above related technologies. During the process of sticking the pathological specimens, the nurse needs to repeat the operations of sticking the cotton swabs and loading the pathological specimens into the bottles. Especially when dealing with pathological specimens from multiple sites, the operations of medical staff are rather cumbersome, which prolongs the sampling time of the pathological specimens and increases the work burden of the medical staff. Content of the Utility Model

Detailed implementation mode

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0035] The following refers to Figures 1 to 4 to further elaborate on the present utility model.

[0036] Refer to Figure 1 , a pathological specimen collection bottle for endoscopic examination sampling, comprising a bottle body 1 and a cover body 11. A rod body 12 is detachably connected to the bottom of the cover body 11. An external thread 13 is fixedly arranged on the outer part of the bottle mouth of the bottle body 1. A first internal thread 14 adapted to the external thread 13 is arranged on the inner wall of the cover body 11. A connection ring 15 is fixedly arranged at one end of the cover body 11 away from the rod body 12. A second internal thread 16 adapted to the external thread 13 is fixedly arranged on the inner wall of the connection ring 15. Of course, in some other alternative embodiments, a smooth hole without the internal thread 16 can also be arranged on the inner wall of the connection ring 15. At that time, the smooth hole on the connection ring 15 can be directly sleeved on the external thread 13 of the bottle body 1.

[0037] An installation part 2 is fixedly arranged at one end of the rod body 12 away from the cover body 11.

[0038] Among them, refer to Figure 1 , 2 , a connection part 3 is fixedly arranged on the inner top wall of one end of the cover body 11 close to the bottle body 1. A connection hole 31 is opened on the connection part 3 for the rod body 12 to be inserted and connected.

[0039] As an implementation manner of the present utility model, the materials of the rod body 12 and the connecting portion 3 are both set as high molecular plastics. Both the rod body 12 and the connecting portion 3 are allowed to have certain elastic deformations. During the actual use process, the diameter of the rod body 12 is slightly larger than the diameter of the connecting hole 31. Therefore, the fitting relationship between the rod body 12 and the connecting hole 31 is interference fit or interference tight fit. The position of the rod body 12 on the connecting portion 3 is limited by the frictional force between the rod body 12 and the inner wall of the connecting hole 31. At this time, the rod body 12 can be disassembled and taken conveniently and quickly.

[0040] Among them, referring to Figure 2 , the installation portion 2 is set in an umbrella shape. The tip of the installation portion 2 is arranged on the side away from the rod body 12. The rod body 12 is fixedly connected to the horizontal end surface of the installation portion 2.

[0041] Referring to Figure 1 、 2 , a limiting ring 4 is fixedly arranged at the bottle mouth of the bottle body 1. The limiting ring 4 is arranged below the external thread 13. The top of the limiting ring 4 is used to abut against the cover body 11 to limit the position of the cover body 11 on the bottle body 1. The outer diameter of the limiting ring 4 is larger than the inner diameter of the cover body 11. When the cover body 11 is installed on the bottle body 1, as the cover body 11 rotates, the lower edge of the cover body 11 abuts against the limiting ring 4. At this time, the rotation of the cover body 11 can be limited. At the same time, as a possible implementation manner of the present utility model, the material of the limiting ring 4 is set as silicone rubber, which has a large friction coefficient and allows certain elastic deformations. It can not only limit the position of the cover body 11, but also play a good protection effect on the edge of the cover body 11 and the bottle body 1.

[0042] Among them, referring to Figure 3 、 4 , as another implementation manner of the present utility model, an installation hole 5 is radially opened at one end of the rod body 12 away from the installation portion 2. A limiting pin 51 is slidably arranged in the installation hole 5. A sliding groove 52 for the limiting pin 51 to slide and connect is opened on the connecting portion 3. The sliding groove 52 is opened along the axial direction of the connecting portion 3, and one end of the sliding groove 52 close to the installation portion 2 is penetrated. A limiting hole 53 for the limiting pin 51 to insert is opened on the inner wall of the sliding groove 52. A first elastic member 54 is arranged in the installation hole 5. The first elastic member 54 is used to drive the limiting pin 51 to move in a direction away from the installation hole 5.

[0043] Referring to Figure 4, a ring-shaped anti-disengagement portion 55 is provided at the orifice of the mounting hole 5. The inner diameter of the anti-disengagement portion 55 is adapted to the diameter of the limit pin 51. A retaining ring 56 is fixedly provided at the tail of the limit pin 51. The diameter of the retaining ring 56 is larger than the diameter of the limit pin 51 and also larger than the inner diameter of the anti-disengagement portion 55, and the diameter of the retaining ring 56 is adapted to the inner diameter of the mounting hole 5, so that the retaining ring 56 can slide within the mounting hole 5. During actual use, one side wall of the retaining ring 56 abuts against the inner side wall of the anti-disengagement portion 55, thereby achieving the effect of preventing the limit pin 51 from disengaging from the mounting hole 5.

[0044] As an embodiment of the present invention, referring to Figure 4 , the first elastic member 54 is arranged as a compression spring. The first elastic member 54 is arranged within the mounting hole 5. One end of the first elastic member 54 abuts against the tail of the limit pin 51, and the other end abuts against the inner wall of the mounting hole 5.

[0045] Among them, referring to Figure 4 , a guiding inclined surface 57 is provided at the opening of the sliding groove 52 near one end of the mounting portion 2. The depth of the sliding groove 52 is less than the length of the limit pin 51 extending out of the mounting hole 5 in the natural state. The guiding inclined surface 57 is used to abut against the end of the limit pin 51. The end of the limit pin 51 is arranged as a spherical shape. The depth of the limit hole 53 is less than the diameter of the end of the limit pin 51. During actual use, the end of the limit pin 51 first abuts against the guiding inclined surface 57. As the rod body 12 is further inserted, the limit pin 51 moves towards the inside of the mounting hole 5 under the pressure of the guiding inclined surface 57. At this time, the first elastic member 54 is compressed. When the end of the limit pin 51 moves within the sliding groove 52, the first elastic member 54 is always in a compressed state. After the end of the limit pin 51 is inserted into the limit hole 53, the first elastic member 54 remains in a compressed state.

[0046] Referring to Figure 4 , the limit hole 53 is arranged as an arc-shaped concave hole. After the end of the limit pin 51 extends into the limit hole 53, it can play a certain role in limiting and positioning the rod body 12 within the connecting hole 31. However, when the pulling force applied by the staff on the rod body 12 is relatively large, the limit pin 51 can still disengage from the limit hole 53. At this time, the rod body 12 can be detached from the cover body 11, and the rod body 12 and the mounting portion 2 can be cleaned, disinfected, and replaced.

[0047] As an embodiment of the present invention, referring to Figure 4 , the end of the limit pin 51 is arranged as a spherical shape. When the limit pin 51 slides within the sliding groove 52, its spherical end can effectively reduce the friction between it and the inner wall of the sliding groove 52. At the same time, it can also reduce the friction between the end of the limit pin 51 and the inner wall of the limit hole 53 to a certain extent. While facilitating the operation of the staff, it can also reduce wear and improve the overall service life of the device.

[0048] Reference Figure 1 、 2 There is an anti-slip pattern 6 on the outside of the cover body 11. By setting the anti-slip pattern 6, the friction between the hands of the staff and the cover body 11 can be effectively increased, facilitating the staff to drive the cover body 11 to deflect.

[0049] Reference Figure 5 、 6 As an embodiment of the present utility model, the installation part 2 includes a receiving part 21 and a top cover 22. A receiving cavity 23 for holding specimens is provided in the receiving part 21. The top of the receiving cavity 23 is open, and the top cover 22 is covered on the top opening of the receiving part 21. The top cover 22 and the top of the receiving part 21 can be connected to each other by a snap-fit method. As another possible embodiment of the present utility model, the top cover 22 and the receiving part 21 can also be fixedly connected by a heat fusion connection method.

[0050] Among them, referring to Figure 5 、 6 a through hole 24 communicating with the receiving cavity 23 is provided on the top cover 22. A sealing plate 25 is rotatably provided on the top cover 22. The sealing plate 25 is used to close or open the through hole 24. The shape of the sealing plate 25 is adapted to the through hole 24. The projected area of the sealing plate 25 on the horizontal plane is larger than the opening area of the through hole 24.

[0051] Reference Figure 6 、 7 a driving member 26 is provided on the top cover 22. The driving member 26 is used to drive the sealing plate 25 to deflect to open or close the through hole 24. As an embodiment of the present utility model, the driving member 26 is set as a driving shaft.

[0052] Among them, referring to Figure 7 、 8 a vertical hole 27 penetrating the top cover 22 is provided on the top cover 22 in the vertical direction. The driving member 26 is rotatably provided in the vertical hole 27 in the vertical direction. The diameter of the vertical hole 27 is adapted to the diameter of the driving member 26. The sealing plate 25 is fixedly installed at one end of the driving member 26 located in the receiving cavity 23. The top of the sealing plate 25 is used for sliding connection with the bottom of the top cover 22. A driving part 28 is fixedly provided at the top end of the sealing plate 25 away from the receiving part 21. A driving groove 281 is provided on the driving part 28. As an embodiment of the present utility model, referring to Figure 6, the shape of the driving groove 281 is set as a cross groove. When it is necessary to put a pathological specimen into the accommodating cavity 23, the staff only needs to insert the tip of the forceps for clamping the specimen or other tools into the driving groove 281, and then rotate the driving part 28 to drive the driving member 26 to deflect in the vertical hole 27. As the driving member 26 rotates, the sealing plate 25 can be driven to deflect, so as to drive the sealing plate 25 to open the through hole 24. At this time, the staff can put the collected pathological specimen into the accommodating cavity 23 through the opened through hole 24. After the collection of the pathological specimen is completed, the staff drives the driving part 28 to rotate in the reverse direction, and the sealing plate 25 can be driven to close the through hole 24.

[0053] Refer to Figure 7 , 8 , a second elastic member 29 is arranged on the top cover 22, and the second elastic member 29 is used to drive the sealing plate 25 to move away from the accommodating part 21.

[0054] Furthermore, refer to Figure 7 , as another implementation manner of the present utility model, an installation ring 7 is rotatably arranged on one side of the top cover 22 away from the accommodating part 21, the driving member 26 rotates and passes through the installation ring 7, and the inner diameter of the installation ring 7 is adapted to the diameter of the driving member 26; a circular groove 71 is opened at the top of the top cover 22 away from the accommodating part 21, the circular groove 71 is arranged along the circumferential direction of the vertical hole 27, and an annular block 72 is slidably arranged in the circular groove 71, and the top of the annular block 72 is fixedly connected to the bottom of the installation ring 7.

[0055] As an implementation manner of the present utility model, refer to Figure 7 , the circular groove 71 is opened as a T-shaped groove, and the annular block 72 is arranged as a T-shaped block adapted to the circular groove 71; as another possible implementation manner of the present utility model, the circular groove 71 can also be opened as a dovetail groove, and the annular block 72 is arranged as a dovetail block adapted to the annular block 72. Through the above settings, the installation ring 7 can only rotate along the axial direction of the vertical hole 27 on the top of the top cover 22 and cannot generate longitudinal displacement in the axial direction of the vertical hole 27.

[0056] Refer to Figure 7 , 8, as an implementation manner of the present utility model, the second elastic member 29 is arranged as a compression spring. One end of the second elastic member 29 abuts against the mounting ring 7, and the other end abuts against the bottom of the driving portion 28. During actual use, the second elastic member 29 is always in a compressed state, thereby acting on the driving member 26, so that the driving member 26 always has a tendency to move in a direction away from the accommodating portion 21, and then drives the top of the sealing plate 25 to always abut against the bottom of the top cover 22, enabling a certain contact pressure to be generated between the top of the sealing plate 25 and the bottom of the top cover 22, thereby being able to prevent the driving member 26 from deflecting in position in a state without being manually toggled, improving the practicability and reliability of the device.

[0057] Referring to Figure 7 , 8 , as an implementation manner of the present utility model, there are two annular blocks 72, and the two annular blocks 72 are symmetrically arranged on both sides of the driving member 26 along the axial direction of the driving member 26.

[0058] In addition, referring to Figure 5 , through holes 8 are provided through the top cover 22 and the sealing plate 25.

[0059] During actual use, when it is necessary to store the collected specimens, the staff rotates the cover body 11, removes the cover body 11 from the bottle body 1, then flips the cover body 11, and slews the cover body 11 over the external thread 13 of the bottle body 1 through the second internal thread 16 or the light hole on the inner wall of the connecting ring 15, so that the rod body 12 is arranged upward. Then the staff inserts forceps or other tools into the driving groove 281 and presses the driving portion 28 downward, thereby driving the driving member 26 to move downward. A vertical relative displacement is generated between the driving member 26, the mounting ring 7 and the top cover 22, and then the sealing plate 25 is driven to be separated from the bottom of the top cover 22. Subsequently, rotating the driving member 26 can drive the sealing plate 25 to deflect, thereby opening the through hole 24. At this time, the staff can place the collected pathological specimens into the accommodating cavity 23 through the opened through hole 24; after the collection of the pathological specimens is completed, the staff presses the driving portion 28, drives the driving member 26 to move downward, separates the sealing plate 25 from the bottom of the top cover 22, then drives the driving member 26 to rotate in the reverse direction, and finally closes the through hole 24 with the sealing plate 25. After the collection of the pathological specimens is completed, flip the cover body 11, and the mounting portion 2 and the rod body 12 can be placed back into the bottle body 1. The protective liquid reserved in the bottle body 1 enters the accommodating cavity 23 through the through hole 8, playing a role in protecting the pathological specimens in the accommodating cavity 23.

[0060] The implementation principle of an endoscopic pathological specimen collection bottle proposed by an embodiment of the present utility model is:

[0061] In actual use, when it is necessary to take pathological specimens from multiple parts of the patient, the staff first rotates the cover 11 to unscrew the cover 11 from the bottle body 1, then flips the cover 11, and flips the cover 11 over and sleeves it on the external thread 13 of the bottle body 1 through the second internal thread 16 or the light hole on the inner wall of the connecting ring 15, so that the rod body 12 is set upward. At this time, the staff can insert tweezers or other tools into the driving groove 281, press the driving part 28 downward, and then drive the driving member 26 to move downward, and a vertical relative displacement is generated between the driving member 26 and the mounting ring 7 and the top cover 22, and then drive the sealing plate 25 to break contact with the bottom of the top cover 22, and then rotate the driving member 26 to drive the sealing plate 25 to deflect, thereby opening the through hole 24. At this time, the staff The collected pathological specimen can be placed in the accommodating chamber 23 through the opened through hole 24; after completing the collection of the pathological specimen, the staff presses the driving part 28 to drive the driving member 26 to move downward, so that the sealing plate 25 is out of contact with the bottom of the top cover 22, and then drives the driving member 26 to rotate in the opposite direction, and finally makes the sealing plate 25 seal the through hole 24. After completing the collection of the pathological specimen, the cover body 11 is flipped over, and the mounting part 2 and the rod body 12 can be put back into the bottle body 1. The protective liquid reserved in the bottle body 1 enters the accommodating chamber 23 through the liquid inlet hole 8, thereby protecting the pathological specimen in the accommodating chamber 23. In the above process, the medical staff only needs to complete the adhesion of the pathological specimen, thereby effectively simplifying the operation of the medical staff and reducing the workload of the medical staff.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
