[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] Example 1

[0037] Reference Figure 1-9 , which is the first embodiment of the present invention, provides a digestive endoscope auxiliary inspection device, the digestive endoscope auxiliary inspection device comprises a cable tube 1, one end of the cable tube 1 is connected to an endoscope body 11, and one end of the cable tube 1 close to the endoscope body 11 is equipped with a mobile sampling component 5;

[0038] The mobile sampling assembly 5 includes a jacket assembly 51, and the end of the jacket assembly 51 close to the endoscope body 11 is connected to the propulsion assembly 52, and the end of the propulsion assembly 52 close to the endoscope body 11 is provided with a first connecting member 53, and the end of the jacket assembly 51 away from the propulsion assembly 52 is provided with a second connecting member 54, and the first connecting member 53 and the second connecting member 54 are respectively assembled with the cable tube 1, and the jacket assembly 51 includes a sleeve 511, and a positioning sleeve 513 is coaxially installed in the sleeve 511, and the sleeve 511 is away from the second connecting member. One end of the connecting member 54 is an open end, and the end of the sleeve 511 close to the second connecting member 54 is a closed end. The closed end of the sleeve 511 is sleeved outside the cable tube 1, and the positioning sleeve 513 is sleeved outside the cable tube 1. The propulsion assembly 52 includes a sliding sleeve 521, and the sliding sleeve 521 is movably sleeved outside the positioning sleeve 513. The end of the sliding sleeve 521 close to the second connecting member 54 is concentrically connected to the piston sleeve 522, and the end of the sliding sleeve 521 away from the piston sleeve 522 is concentrically movably connected to the rotating sleeve 523. One side of the rotating sleeve 523 is connected There is a sampling box 524, one end of the sleeve 511 close to the second connecting piece 54 is connected to the boosting pipe 4, the other end of the boosting pipe 4 is connected to the boosting pump 41 close to the cable tube 1, and a sealed cavity is formed between the end of the piston sleeve 522 close to the second connecting piece 54 and the inner wall of the sleeve 511. When the boosting pump 41 increases the pressure to the sleeve 511, the piston sleeve 522 moves axially along the positioning sleeve 513 to drive the sampling box 524 to move axially. The sampling box 524 is connected to the sampling tube 3, and the inner wall of the rotating sleeve 523 is annular. A plurality of racks 528 are arranged at equal intervals, a motor 527 is arranged on one side of the rack 528, the motor 527 is connected to the outer wall of the sliding sleeve 521, the motor 527 is transmission-connected to a gear roller 526 meshing with the rack 528, the motor 527 is used to drive the sampling box 524 to rotate in a circle, a sampling port is provided on the side of the sampling box 524 away from the rotating sleeve 523, the other end of the sampling tube 3 is connected to the sampling pump 31 close to the cable tube 1, and the sample at the position of the sampling box 524 can be sucked by controlling the sampling pump 31.

[0039] Combined with Figure 3 , Figure 4 , Figure 7 and Figure 8 Two first limiting strips 14 are symmetrically installed on the outer wall of the cable tube 1, and two first limiting grooves 515 are symmetrically opened on the inner wall of the positioning sleeve 513. The first limiting strips 14 slide in cooperation with the first limiting grooves 515. A first threaded portion 12 is provided at one end of the cable tube 1 close to the endoscope body 11, and a second threaded portion 13 is provided at one end of the cable tube 1 away from the endoscope body 11. The outer diameter of the second threaded portion 13 is greater than the outer diameter of the first threaded portion 12. One end of the positioning sleeve 513 extends to a position close to the second threaded portion 13, and the other end extends to a position close to the first threaded portion 12, so that the sleeve 511 and the cable tube 1 remain fixedly positioned. When the cable tube 1 is stationary, the sleeve 511 is stationary.

[0040] Combined with Figure 3 , Figure 5 and Figure 7 The end of the positioning sleeve 513 close to the second threaded portion 13 is fixedly connected to the inner wall of the sleeve 511, and the piston sleeve 522 is limited to slide between the inner wall of the sleeve 511 and the outer wall of the positioning sleeve 513. Two second limiting grooves 529 are symmetrically opened on the inner wall of the sliding sleeve 521, and two second limiting strips 514 are symmetrically installed on the outer wall of the positioning sleeve 513. The second limiting strips 514 slide in cooperation with the second limiting grooves 529, so that the sliding sleeve 521 and the positioning sleeve 513 maintain axial limited sliding. When the circumferential position of the positioning sleeve 513 remains unchanged, the boost pipe 4 pressurizes the sleeve 511 to drive the sliding sleeve 521 to move axially along the positioning sleeve 513.

[0041] Combined with Figure 4-6 , one end of the sliding sleeve 521 away from the second limiting groove 529 is concentrically sleeved with two fixed rings 525, and the two ends of the rotating sleeve 523 are concentrically connected with end sleeves 5231, respectively. The end sleeves 5231 are sealed and movably connected with the two corresponding fixed rings 525, and the movable connecting parts are sealed bearings. The motor 527 and the gear roller 526 are located between the two fixed rings 525. The outer diameter of the fixed ring 525 is larger than the inner diameter of the sleeve 511. Since the sliding sleeve 521 cannot rotate in a circle, when the motor 527 drives the gear roller 526 to rotate, the gear roller 526 engages with the rack 528 to drive the rotating sleeve 523 to rotate, and the rotating sleeve 523 and the sliding sleeve 521 rotate in a circle relative to each other, so that the sampling box 524 can rotate in a circle to the corresponding sampling position.

[0042] Combined with Figure 5 and Figure 6 At least one baffle 5281 is installed on the inner wall of the rotating sleeve 523, and at least one baffle 5281 is located on a side close to the rack 528 located at the end. The setting of the baffle 5281 ensures that during the engagement process between the toothed roller 526 and the rack 528, the rotating sleeve 523 is limited to a forward rotation of no more than 360°, or a reverse rotation of no more than 360°.

[0043] The working principle is that after the mobile sampling assembly 5 is assembled at one end of the cable tube 1 close to the endoscope body 11, the sampling pump 31 and the booster pump 41 are located at the end of the cable tube 1 farthest from the endoscope body 11, and the endoscope body 11 is inserted for inspection, the sampling position is determined by the imaging of the endoscope body 11. After the sampling position is confirmed, the pressure is increased or reduced by the booster pump 41, and the piston sleeve 522 is controlled to move axially in the sleeve 511, so that the sampling box 524 moves to the approximate position where the sample is located, and then the gear roller 526 is driven to rotate by controlling the motor 527 to make the rotating sleeve 523 rotate in a forward or reverse circle, so that the sampling box 524 moves to capture the specific sample concentration position, and then the sampling pump 31 is controlled to make the sampling box 524 absorb the sample, thereby achieving the effect of assisting the digestive endoscopy to accurately sample.

[0044] Example 2

[0045] Reference Figure 1-9 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0046] A silicone sleeve 512 is concentrically connected to the outer wall of one end of the sleeve 511 away from the second connecting piece 54, and the end of the sleeve 511 close to the silicone sleeve 512 is an open end. The other end of the silicone sleeve 512 is fixedly connected to the outer wall of the rotating sleeve 523, and two fixing rings 525 are movably connected to the two ends of the rotating sleeve 523, so that the rotating sleeve 523 remains sealed to prevent the sample from entering the rotating sleeve 523. When the rotating sleeve 523 moves axially, the silicone sleeve 512 ensures the sealing state between the sleeve 511 and the rotating sleeve 523 to prevent the sample from entering the sleeve 511.

[0047] Combined with Figure 1 , Figure 2 , Figure 4 and Figure 8 The first connecting piece 53 is composed of a sleeve and a hexagonal nut sleeve, and the second connecting piece 54 is composed of a sleeve and a hexagonal nut sleeve. The inner diameter of the hexagonal nut sleeve of the first connecting piece 53 is smaller than the inner diameter of the hexagonal nut sleeve of the second connecting piece 54. The sleeve of the first connecting piece 53 abuts against the positioning sleeve 513, and the sleeve of the second connecting piece 54 abuts against the sleeve 511. The second connecting piece 54 is connected to the second threaded portion 13, and then the outer sleeve assembly 51 and the propulsion assembly 52 are slid onto the outside of the cable tube 1, and then the first connecting piece 53 is connected to the first threaded portion 12, so that the mobile sampling assembly 5 and the cable tube 1 can be quickly assembled.

[0048] Combined with Figure 1 and Fig. 9The outer wall of the cable tube 1 is provided with a plurality of tube clamp assemblies 2, and the tube clamp assemblies 2 include a tube clamp seat 21 and a sleeve 23. Two card slots 22 are symmetrically provided on the inner side of the tube clamp seat 21, and two card blocks 24 are symmetrically installed on the outer wall of the sleeve 23. The card blocks 24 are engaged with the card slots 22, and the tube clamp seat 21 is connected to the outer wall of the cable tube 1. The sleeve 23 is interference-engaged with the sampling tube 3 or the booster tube 4. A plurality of sleeves 23 are sleeved on the outer wall of the sampling tube 3 or the outer wall of the booster tube 4. After the mobile sampling assembly 5 is assembled with the cable tube 1, the card blocks 24 corresponding to the sleeves 23 are engaged with the card slots 22 corresponding to the tube clamp seat 21, so that the sampling tube 3 or the booster tube 4 is positioned along the outer wall of the cable tube 1 to avoid being inserted into the cable tube 1 for inspection.

[0049] Working principle: when the mobile sampling assembly 5 is installed with the cable tube 1, first disassemble the endoscope body 11 and the cable tube 1, then move the second connecting piece 54 from the end of the cable tube 1 to the position of the second threaded portion 13, and the hexagonal nut sleeve of the second connecting piece 54 is threadedly connected and fixed with the second threaded portion 13, then put the outer sleeve assembly 51 and the propulsion assembly 52 on the end of the cable tube 1, and then put the first connecting piece 53 on the end of the cable tube 1, and the hexagonal nut sleeve of the first connecting piece 53 is connected with the first threaded portion 12, and the outer sleeve assembly 51 and the propulsion assembly 52 are pressed between the first connecting piece 53 and the second connecting piece 54, and then the sleeve 23 of the sampling tube 3 and the boosting tube 4 is clamped and positioned with the tube clamp seat 21 on the outer wall of the cable tube 1, and finally the endoscope body 11 is installed on the end of the cable tube 1, and the assembly of the mobile sampling assembly 5 and the cable tube 1 is completed.
