[0031] In this embodiment, each gripper is an arc-shaped gripper. The two grippers are divided into a first gripper 201 and a second gripper 202. The arc-shaped shapes of the first gripper 201 and the second gripper 202 will not scratch the inner wall of the patient's intestine, and the arc-shaped shapes of the first gripper 201 and the second gripper 202 are adapted to the shape of feces after closing, making it easy to load and take feces; further, each gripper is provided with a plurality of filter holes 203, and the plurality of filter holes 203 are convenient for filtering liquids other than hard feces.

[0032] In this embodiment, the abutting parts of the two grippers are provided with mutually meshing saw teeth 204. The meshing saw teeth 204 are used to cut off long strips of hard feces to avoid the situation where the length of the hard feces is greater than the length of the grippers and the hard feces cannot be grasped. Specifically, the saw teeth 204 are only provided at the abutting parts at the top of the first gripper 201 and the second gripper 202. After the first gripper 201 and the second gripper 202 are opened, the saw teeth 204 are only aimed at the feces to be cut and taken out. The arc-shaped outer wall of the gripper abuts against the inner wall of the patient's intestine. There is a certain distance between the saw teeth 204 and the inner wall of the intestine. The saw teeth 204 will not touch the inner wall of the patient's intestine and will not cause damage to the inner wall of the patient's intestine.

[0033] In this embodiment, the gripping portion 20 includes a connecting portion 205 and two grippers rotatably connected to the connecting portion 205. Two fixed shafts are provided in the connecting portion 205, each of which is connected to a gear. The two gears are of the same size and number of teeth, mesh with each other, and are each fixedly connected to a gripper. One end of a driving line 40 that can drive the gear to rotate outward is fixed to one of the gears, and the driving portion 30 controls the gear with the driving line 40 to rotate outward. Specifically, the inner front wall of the connecting portion 205 is provided with a first fixed shaft and a second fixed shaft (not shown in the exploded view), and the two gears are respectively a first gear 206 and a second gear 207. The first fixed shaft is vertically connected to the middle position of the front end face of the first gear 206, and the second fixed shaft is vertically connected to the middle position of the front end face of the second gear 207, that is, the first gear 206 is fixedly connected to the connecting portion 205 through the first fixed shaft, and the second gear 207 is fixedly connected to the connecting portion 205 through the second fixed shaft; the rear end face of the first gear 206 is provided with a first connecting column for fixedly connecting to the first gripper 201 208, the rear end face of the second gear 207 is provided with a second connecting column 209 for being fixedly connected to the second gripper 202; the front end face of the first gear 206 is fixed with one end of the driving wire 40, and the one end of the driving wire 40 is also abutted against the upper edge of the first fixed shaft; the front end face of the first gear 206 can be fixed with one end of the driving wire 40, either directly, or a winding column can be provided below the front end face of the first gear 206, one end of the driving wire 40 is fixedly wound around the winding column, and then one end of the driving wire 40 is abutted against the upper edge of the first fixed shaft; the driving wire 40 is made of a material that is not easily broken by pulling, such as iron wire.

[0034] In this embodiment, the connecting portion 205 is provided with a baffle 2051 for preventing feces from getting stuck in the two gears, and the baffle 2051 is provided with at least one through hole 2052. Specifically, the top of the connecting portion 205 is provided with a baffle 2051 to prevent large hard feces that cannot be cleaned by conventional cleaning means from getting stuck in the gears and affecting the operation of the gears; and a through hole 2052 is provided to leave space for the first connecting column 208, the second connecting column 209 and the rotation path of the two.

[0035] In this embodiment, the elastic part 50 is a torsion spring, which includes a spring coil and torsion arms arranged at both ends of the spring coil. The spring coil is sleeved on a fixed shaft corresponding to another gear, and the two torsion arms are fixedly connected to the inner wall of the connecting part 205 and the end face of another gear respectively. Furthermore, the torsion spring is provided with an anti-rust layer to extend the service life of the torsion spring. Specifically, the spring coil is sleeved on the second fixed shaft, and the two torsion arms are fixedly connected to the inner wall of the connecting part 205 and the front end face of the second gear 207 respectively.

[0036] In addition to being arranged on the second gear 207, the torsion spring can also be arranged at the connection between the gripper and the connecting part 205. Specifically, two torsion springs are arranged in total, and the connection between each gripper and the connecting part 205 is arranged on the third fixed shaft, the spring coil is sleeved on the third fixed shaft, and the two torsion arms are respectively fixedly connected to the inner wall of the connecting part 205 and the inner wall of the gripper. When the pull-down driving part 30 stops, the torsion spring directly drives the gripper back to the initial closed position. If the torsion spring is arranged at the connection between the gripper and the connecting part 205, then the baffle 2051 is also provided with a through hole 2052 to leave space for the torsion spring.

[0037] In this embodiment, the operating end of the colonoscope body 10 is provided with a sliding groove 60, and the sliding groove 60 is slidably adapted to be provided with the driving part 30. The gripper can be manipulated to open by pressing the driving part 30 with a hand to make it slide downward in the sliding groove 60, and after the hand is released, the driving part 30 automatically slides up to the original position under the action of the elastic part 50, and the operation is simple; further, at least part of the driving part 30 is located outside the sliding groove 60, so that it is convenient to manipulate the driving part 30 to slide up and down.

[0038] The working principle of the colonoscope device for taking hard feces proposed in the utility model is as follows:

[0039] First, place the entire colonoscope device into the patient's intestine, and then move the position to locate the hard feces to be taken. Pull the other end of the drive wire 40 to move its position toward the operating end. At this time, one end of the drive wire 40 fixed to the front end surface of the first gear 206 moves along the first fixed axis first toward the visible end of the colonoscope body 10, and then moves down toward the operating end, so that the entire first gear 206 rotates outward. While the first gear 206 rotates outward, the second gear 207 meshing with it also rotates outward, that is, the second gear 207 rotates to the left, and the first gear 206 rotates to the right, and the two grippers connected to the two gears through the connecting column also rotate together, thereby realizing the opening of the two grippers.

[0040] After opening, the two grippers successfully grab the feces, then release the grippers and stop operating the driving unit 30. The second gear 207 rotates inward under the action of the torsion spring, and the first gear 206 meshing with the second gear 207 also rotates inward, driving the two grippers to close at the same time, and the driving unit 30 automatically slides back to the initial position under the drive of the first gear 206. After closing, the entire colonoscope device is moved out of the patient's intestines and taken out of the body, and then the grippers are opened in the same steps as above to release the feces to the designated position.

[0041] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
