[0037] Reference Figures 1 to 3As shown, an embodiment of the utility model provides a medical endoscope measuring device, comprising a handle 1, a measuring component 2 and an adjusting component 3. A cavity 11 is provided in the handle 1, and the adjusting component 3 is installed in the cavity 11. The measuring component 2 is arranged on one side of the handle 1, and the adjusting component 3 is able to drive the measuring component 2 to bend. In the process of measuring the size of the lesion, the measuring component 2 can be controlled by the adjusting component 3 to be bent to be nearly parallel to the lesion, so that the measuring component 2 can accurately measure the size of the lesion, thereby improving the measurement accuracy and providing a reliable basis for the subsequent formulation of a treatment plan for the patient.

[0038] like Figure 4 As shown, the measuring assembly 2 includes a pipe 21, a bending piece and a measuring ruler 23. One end of the pipe 21 is inserted into the cavity 11, and the bending piece includes at least two bending rings 22. The two bending rings 22 are rotatably connected, wherein one end of one bending ring 22 is connected to an end of the pipe 21 away from the cavity 11, and one end of the other bending ring 22 is connected to the measuring ruler 23, and the bending ring 22 is suitable for driving the measuring ruler 23 to bend. Each bending ring 22 is provided with at least one limiting ring 221, and the limiting ring 221 is formed by being recessed from the outer surface of the bending ring 22 toward the center of the circle thereof. The adjusting assembly 3 includes a rotating disk 31 and a connecting piece 32, wherein the outer diameter of the connecting piece 32 is less than or equal to the inner diameter of the limiting ring 221, one end of the connecting piece 32 is fixed on the rotating disk 31, and the other end of the connecting piece 32 passes through the limiting ring 221 and is connected to the measuring ruler 23. In this embodiment, the rotating disk 31 can be rotated, and the rotating disk 31 can pull the measuring ruler 23 by tightening or loosening the connecting piece 32. At the same time, the connecting piece 32 can adjust the bending angle of the measuring ruler 23 by controlling the relative rotation between the two bending rings 22. Therefore, in the actual operation process, the bending degree of the bending piece can be adjusted according to the position of the lesion, so that the measuring ruler 23 is rotated to be roughly parallel to the lesion, and then the size of the lesion can be accurately measured by the scale on the measuring ruler 23. The measurement process of this embodiment is simple and convenient, and the accuracy is high. At the same time, in the actual operation process, the position of the measuring ruler 23 can be adjusted according to the specific position of the lesion, which ensures its measurement accuracy and improves its practicality.

[0039] like Figures 5 to 7As shown, a cylinder 311 and a stopper 312 are provided on the turntable 31. The stopper 312 is fixed to one side of the cylinder 311. The diameter of the stopper 312 is larger than the diameter of the cylinder 311. One end of the connecting member 32 is wound around the cylinder 311, and the stopper 312 can stop the connecting member 32 on the cylinder 311. A ring 313 is sleeved on the outer side of the cylinder 311. The inner diameter of the ring 313 is equal to the diameter of the stopper 312. The ring 313 is clamped on the outer side of the stopper 312, and is suitable for clamping the connecting member 32 on the cylinder 311. In actual operation, one end of the connector 32 can be fixed on the cylinder 311 and wrapped around the cylinder 311 for several turns, and then the connector 32 is passed through the through hole 314 on the limit block 312, and then the ring 313 is sleeved on the outside of the limit block 312, thereby achieving the fixation between the connector 32 and the cylinder 311. By fixing the connector 32 and the cylinder 311 by the above method, the turntable 31 can tighten or loosen the connector 32 when the turntable 31 is rotated, thereby achieving the bending of the measuring ruler 23 by pulling the measuring ruler 23 through the connector 32 and bending the bending piece, so that the measuring ruler 23 can be bent to be nearly parallel to the lesion to be measured, thereby achieving the purpose of accurately measuring the size of the lesion.

[0040] like Figure 5 As shown, the stop block 312 is provided with a through hole 1 314, the turntable 31 is provided with a through hole 2 315, and one side of the connector 32 passes through the through hole 1 314, the through hole 2 315 and the pipe 1 21 and is connected to the measuring ruler 23. In actual operation, one end of the connector 32 is fixedly connected to the cylinder 311, and the other end of the connector 32 is connected to the measuring ruler 23. Therefore, if the turntable 31 is rotated, the length of the connector 32 between the measuring ruler 23 and the cylinder 311 will change, so that under the action of the connector 32, the bending member will bend, and the bending member can drive the measuring ruler 23 to move until the measuring ruler 23 moves to be nearly parallel to the lesion, thereby achieving the purpose of measuring the size of the lesion.

[0041] In actual operation, the measuring ruler 23 is inserted from the endoscope channel hole in a straight state (i.e., the measuring ruler 23 and the pipe 21 are in the same straight line). After entering the body, the connecting member 32 can be stretched or relaxed by turning the dial 31 on the handle 1, so that the measuring ruler 23 can be bent at 0° to 90°. During measurement, the measuring ruler 23 can be controlled to be nearly parallel to the lesion according to actual conditions, and then the size of the lesion can be obtained by observing the scale of the measuring ruler 23. The measuring ruler 23 is adjusted to bend by adjusting the component 3, so that the measuring ruler 23 can be bent to be nearly parallel to the lesion, further improving the measurement accuracy of the measuring ruler 23.

[0042] like Figure 2As shown in FIG. 1 , it is a schematic diagram of the state when the measuring ruler 23 is bent to 90°. In this embodiment, the bending angle of the measuring ruler 23 is between 0° and 90°.

[0043] like Figure 1 and Figure 3 As shown, the handle 1 is an openable and closable structure. The handle 1 includes a cover body 13 and a cover body 2 14. The cover body 2 14 covers the cover body 13, and the cover body 13 and the cover body 2 14 form a cavity 11. By providing the cover body 13 and the cover body 2 14, the handle 1 can be opened quickly by removing the cover body 2 14 from the cover body 1 13, so that the adjustment component 3 installed in the handle 1 is exposed. Therefore, when the adjustment component 3 is damaged, the adjustment component 3 in the cavity 11 can be repaired by quickly opening the cover body 2 14, making the entire repair process simple and convenient.

[0044] A fixing piece is provided on the cover body 13, and the turntable 31 is rotatably mounted on the fixing piece.

[0045] In this embodiment, the fixing member is a cylindrical 311 structure, and two elastic blocks of semi-cylindrical 311 structures are arranged on the top thereof, and the diameter of the cylinder 311 surrounded by the elastic blocks of the two semi-cylindrical 311 structures is larger than the diameter of the fixing member. In actual operation, a circular hole is arranged at the center of the rotating disk 31, and the circular hole is sleeved on the outside of the fixing member, so that the rotating disk 31 can rotate around the fixing member, thereby tightening or loosening the connecting member 32. At the same time, by providing two elastic blocks, the rotating disk 31 can be firmly limited to the cylinder 311, thereby improving the stability of the rotating disk 31 during rotation.

[0046] like Figure 5 and Figure 6 As shown, the handle 1 is provided with a through hole 3 12, which penetrates the handle 1 along the short axis direction of the handle 1, and the through hole 3 12 is connected to the cavity 11. By providing the through hole 3 12, the turntable 31 can extend out of the handle 1 from the cavity 11, thereby adjusting the bending angle of the measuring ruler 23 by holding the handle 1 and pushing and rotating it with fingers. The entire operation process is simple and convenient, and in actual application, the position of the measuring ruler 23 can be adjusted at any time according to actual conditions, thereby improving its practicality.

[0047] In this embodiment, the diameter of the through hole must be greater than the length of the cross section of the turntable 31 extending out of the through hole. By limiting the diameter of the through hole, the through hole will not interfere with the rotation of the turntable 31 during the rotation of the turntable 31, thereby improving the flexibility of the rotation of the turntable 31 and achieving flexible adjustment of the bending degree of the measuring ruler 23 to meet the purpose of measuring different lesions.

[0048] In this embodiment, the length of the turntable 31 extending out of the handle 1 is 0.2 to 0.3 times the diameter of the turntable 31. By limiting the length of the turntable 31 extending out of the handle 1, the turntable 31 can be quickly rotated by the protruding portion of the turntable 31 when the handle 1 is held, so as to achieve the purpose of adjusting the bending of the measuring ruler 23, and at the same time, the situation that the operation is inconvenient due to the large size of the entire measuring device will not occur.

[0049] like Figure 5 and Figure 6 As shown, a pair of guide posts 15 are provided in the cavity 11, and a gap 151 is provided between the pair of guide posts 15, one end of the gap 151 is aligned with the pipe 21, and the other end of the gap 151 is aligned with the through hole 314. By providing the guide posts 15, it is possible to ensure that the connecting member 32 between the measuring ruler 23 and the guide posts 15 moves in a straight line, thereby improving the stability of the connecting member 32 during the movement process, thereby ensuring the stability of the measuring ruler 23 driven by the bending member during the bending process.

[0050] like Figure 6 As shown, a clamping groove 16 is further provided in the cavity 11, and the clamping groove 16 is provided on the side of the guide column 15 away from the rotating disk 31, and the clamping groove 16 is suitable for clamping the pipe 1 21. By providing the clamping groove 16, the pipe 1 21 extending into the cavity 11 can be limited, and the stability of the connection between the pipe 1 21 and the handle 1 is further improved.

[0051] like Figure 5 and Figure 6 As shown, the turntable 31 is provided with a plurality of shifting blocks 316, which are distributed along the circumference of the turntable 31, and the shifting blocks 316 are arc-shaped structures. Two adjacent shifting blocks 316 are connected by an arc transition, and the contact area with the turntable 31 can be increased by providing the shifting blocks 316, so that the turntable 31 can be quickly rotated by the shifting blocks 316, so as to achieve the purpose of adjusting the position of the measuring ruler 23 through the turntable 31 and the connecting member 32.

[0052] In this embodiment, the connecting member 32 may be a steel wire.

[0053] In this embodiment, there are four bending rings 22, which are arranged in sequence along the vertical direction, and two adjacent bending rings 22 are connected in rotation. Among the four bending rings 22, the lowest bending ring 22 is connected to the end of the tube 24 on the road 21 away from the cavity 11, and the highest bending ring 22 is connected to the measuring ruler 23. The bending ring 22 is controlled to bend by adjusting the component 3, thereby driving the position of the measuring ruler 23 to change, so that the measuring ruler 23 can be rotated to be parallel to the lesion, so as to obtain the actual size of the lesion by observing the scale on the measuring ruler 23. The utility model can accurately measure the size of the lesion through the above-mentioned device, effectively solving the problem in the prior art that the size of the lesion can only be estimated by comparing the lesion with tools such as surgical forceps, improving the measurement accuracy of the lesion size, and providing a reliable basis for the subsequent formulation of treatment plans. Each bending ring 22 is provided with at least one limiting ring 221, which is formed by being recessed from the outer surface of the bending ring 22 toward the center thereof. The connecting piece 32 can be connected to the measuring ruler 23 by passing through the limiting ring 221. The limiting ring 221 can ensure the stability of the bending ring 22 during the bending process, and the bending piece can be bent by changing the length of the connecting piece 32.

[0054] In this embodiment, the bending piece can be a whole piece of stainless steel plate formed into a plurality of bending rings 22 by laser cutting.

[0055] like Figure 8 and Fig. 9 As shown, each bending ring 22 includes a rotating member 1 222 and a rotating member 223, which are arranged along the axial direction of the bending ring 22 and located at both ends of the bending ring 22; the rotating member 1 222 on one bending ring 22 is rotatably connected to the rotating member 2 223 on the other bending ring 22. By arranging the rotating member 1 222 and the rotating member 2 223, the bending member can be bent, thereby achieving the purpose of adjusting the position of the measuring ruler 23.

[0056] like Fig. 9 As shown, there are two rotating members 222, and the two rotating members 222 are symmetrically arranged on both sides of the limiting ring 221. By setting two rotating members 222, and the two rotating members 222 are symmetrically arranged on both sides of the limiting ring 221, when the connecting member 32 is pulled, the bending member will only bend along the connecting line direction of the two rotating members 222, so as to ensure the bending direction of the bending member. Therefore, when measuring the lesion, the bending direction of the bending member and the measuring ruler 23 can be estimated by the position of the rotating member 222, so as to avoid contact with the human body during the bending process, thereby improving the safety during the measurement process.

[0057] The number of the second rotating members 223 is the same as the number of the first rotating members 222 .

[0058] like Figure 8 and Fig. 9 As shown, the rotating member 1 222 includes a rotating block 1 224 and a rotating block 225, and a limiting groove 1 226 is formed between the rotating block 1 224 and the rotating block 225. The rotating member 223 can be inserted into the limiting groove 1 226 and wrapped around the outer side of the rotating block 1 224, and the rotating member 223 inserted into the limiting groove 1 226 can rotate around the rotating block 1 224. A limiting groove 227 is provided between the rotating member 223 and the bending ring 22, and the limiting groove 227 is suitable for the rotating block 225 to be inserted, and the rotating block 225 inserted into the limiting groove 227 can be wrapped around the outer side of the rotating member 223. The rotating block 225 and the rotating member 223 are both arc-shaped structures, and the outer diameter of the rotating block 1 224 is the same as the inner diameter of the rotating member 223. In this embodiment, the second rotating member 223 is included on the outside of the first rotating block 224, and the second rotating block 225 is wrapped on the outside of the second rotating member 223, so that the large circular ring 313 is wrapped on the outside of the small circular ring 313. Not only can the two bending rings 22 be relatively rotated to improve the flexibility of rotation, but also the firmness of the connection between the two bending rings 22 can be improved.

[0059] The upper end of the rotating block 1 224 is a circular structure, and the outer diameter of the rotating block 1 224 is the same as the inner diameter of the rotating member 223. By setting the upper end of the rotating block 1 224 as a circular structure, the smoothness of the two bending rings 22 during the rotation process can be improved, thereby achieving better adjustment of the position of the measuring ruler 23, so that the measuring ruler 23 can be bent to any angle between 0° and 90°, thereby improving its practicality.

[0060] The measuring ruler 23 in the utility model is made of silica gel, which has good biocompatibility, no stimulation to human tissue, no toxicity, no allergic reaction, very little body rejection reaction, and good physical and chemical properties, thus avoiding harm to the human body during the measurement process.

[0061] In another embodiment, two adjacent bending rings 22 may be connected by rivets. Connecting by rivets can improve the stability of the connection between the two bending rings 22.
