The application is characterized in that: when the existing endoscope is matched with the treatment instrument to perform sampling operation, the sample collecting bottle and the endoscope are of split type structures, when a collected sample is transferred to the sample collecting bottle by the treatment instrument, the collected sample is likely to be exposed to the external environment, so that hidden danger of indoor environmental pollution exists in the collected sample, and hidden danger of sample pollution exists in the indoor environment. Therefore, the application provides a sample collecting device which is arranged at the position of the instrument mouth on the handle of the endoscope, so that the sample collected by the treatment instrument can be directly released at the position, and the pollution problem caused by sample exposure is avoided; meanwhile, the sample collecting device can reduce the operation difficulty of an operator in the process of inserting and releasing the treatment instrument into the sample through the position relation of the channels, and improve the operation efficiency.

The sample collection device, the endoscope handle and the endoscope provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes thereof with reference to fig. 1 to 16.

The first aspect of the present embodiment provides a sample collection device.

The sample collection device of the present embodiment is applied to an endoscope, and includes a plug 11 and a sample storage container 12, as shown in fig. 1 to 8. The plug body 11 is arranged at an instrument nozzle 21 on the handle of the endoscope, the plug body 11 is provided with a first channel 111 and a second channel 112 which are communicated with each other, the first channel 111 is used for passing a treatment instrument, the second channel 112 is used for passing a sample, and the central axes of the first channel 111 and the second channel 112 are perpendicular to each other; the sample storage container 12 has a sample storage space 121, the sample storage space 121 communicates with the second channel 112, and the sample storage space 121 is disposed coaxially with the second channel 112, as shown in fig. 1 to 11. Fig. 15 and 16 show schematic views of the plug 11 mounted at the instrument mouth 21.

Since the first channel 111 is for passing the treatment instrument, it is known that the first channel 111 is penetrating the plug 11, as shown in fig. 4, 8 and 11. Preferably, the first channel 111 is disposed along the axial direction of the plug 11 and penetrates the plug 11, the second channel 112 is disposed along the radial direction of the plug 11, and the first channel 111 is further in communication with the second channel 112, the sample storage container 12 is disposed below the plug 11, the sample storage space 121 is in communication with the second channel 112, and the sample storage space 121 is disposed coaxially with the second channel 112, as shown in fig. 4 and 8. Specifically, after the plug 11 is mounted on the instrument nozzle 21, the sample storage container 12 connected to the plug 11 is placed in a substantially vertical state, so that the sample enters the sample storage space 121 by using the gravity of the sample itself for collection, as shown in fig. 16.

Specifically, the sampling operation performed by using the sample collection device of the present embodiment includes the following steps:

step 1: inserting a treatment instrument into an instrument channel in the endoscope handle along the first channel 111, and then reaching a site to be sampled along the instrument channel;

step 2: performing a sampling operation with the treatment instrument;

step 3: after the sampling operation is completed, the treatment instrument is retracted to the first channel 111 along the instrument channel, and when the treatment instrument is retracted to the region where the first channel 111 and the second channel 112 are communicated with each other (the region where the first channel 111 and the second channel 112 are communicated with each other means that the region belongs to both the first channel 111 and the second channel 112, that is, the common part of the first channel 111 and the second channel 112), the operator can control the treatment instrument to release the sample, and the sample falls into the sample storage space 121 coaxially arranged with the second channel 112 under the action of self gravity to be collected;

step 4: after the sample is released, the treatment instrument continues to exit along the first channel 111 until the treatment instrument is completely separated from the sample collection device.

Further, after the sampling operation is completed, the endoscope and the sample collecting device can be transferred to a detection chamber for detection and analysis; the sample collection device can be separated from the instrument nozzle 21, and then the sample collection device can be independently transferred to a detection chamber for detection and analysis.

Further, the plug 11 may be made of a transparent material so as to determine whether the treatment instrument is just retracted to the region where the first channel 111 and the second channel 112 communicate with each other; or for a treatment instrument with a larger distal end size, the resistance to passing through the port at the distal end of the plug 11 is larger due to the larger distal end size, and the operator can judge whether the treatment instrument just retreats to the region where the first channel 111 and the second channel 112 communicate with each other by the damping feeling received during the retreating of the treatment instrument.

Further, the aperture of the opening of the first channel 111 near the instrument tube side is smaller than the outer diameter of the treatment instrument, and the first channel 111 is made of an elastic material, so that when the treatment instrument passes through the first channel 111, the first channel can not only support the treatment instrument, but also scrape mucus on the outer wall of the treatment instrument when the treatment instrument exits from the insertion part, and the mucus is prevented from entering the sample storage space 121, so that the reliability of sample collection is ensured.

The sample collection device based on the above scheme is applied to an endoscope, because the sample collection device comprises a plug body 11 and a sample storage container 12, the plug body 11 is provided with a first channel 111 and a second channel 112 which are communicated with each other, the central axis of the first channel 111 and the central axis of the second channel 112 are perpendicular to each other, when a treatment instrument (such as a biopsy forceps) after collecting a sample is retreated to an area where the first channel 111 and the second channel 112 are communicated with each other along the instrument channel, an operator can control the treatment instrument to release the sample, and because the sample storage space 121 of the sample storage container 12 and the second channel 112 are coaxially arranged, the released sample can enter the sample storage space 121 to be collected under the action of gravity. Therefore, the sample collecting device of the embodiment is characterized in that the sample is positioned in the endoscope and cannot be exposed to the external environment in the process of sampling and collecting the sample, so that the hidden danger that the sample is polluted and the indoor environment is polluted can be avoided, the reliability of sample detection can be ensured, the personnel infection risk is reduced, and the indoor environment pollution risk is reduced. Namely, the sample collection device of the embodiment solves the technical problem that samples are exposed when samples collected by a treatment instrument are transferred to a sample collection bottle in the related technology.
