[0002] Currently, length and size are mainly measured using rulers, length measuring instruments, and other devices. However, these are not suitable for locations such as the human body's internal cavities, such as the trachea.

[0003] In modern medical activities, the diameter of the human body's internal cavities and the length of lesions are mainly measured by entering the location of the lesion through an endoscope. The instrument then determines the diameter of the cavity and the length of the lesion at the location based on the image taken by the endoscope. However, because the endoscope will magnify the interior, the tracheal diameter and the length of the lesion at the location displayed on the monitor are not accurate.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] like Figures 1 to 9 As shown, this embodiment provides a device for measuring the cavity diameter and lesion length at a lesion location, comprising a push rod 1 and a handle 2, wherein the handle 2 is sleeved on the push rod 1 and slidably connected thereto;

[0043] The push rod 1 is provided with a length scale bar 11, and the handle 2 is provided with a length indicator head 22 used in conjunction with the length scale bar 11;

[0044] It also includes an opening width measuring tube 6 and a length feeding tube 7, as well as a measuring component;

[0045] The length feed tube 7 is fixedly connected to the handle 2, the width measuring tube 6 is located inside the length feed tube 7 and is slidably connected thereto, one end of the measuring assembly is fixedly connected to the width measuring tube 6, and the other end abuts against the end of the length feed tube 7;

[0046] An amplitude scale bar 21 is provided on the handle 2 , and an amplitude indicator head 8 used in conjunction with the amplitude scale bar 21 is fixed to one end of the open width measuring tube 6 away from the measuring assembly.

[0047] This embodiment provides a handle 2, a push rod 1, an opening width measuring tube 6, a length feed tube 7 and a measuring assembly. The measuring assembly can be used to successively measure the lesion length and the cavity diameter at the lesion location. Through the mutual cooperation of the length indicator head 22 and the length scale bar 11, as well as the mutual cooperation of the amplitude indicator head 8 and the amplitude scale bar 21, the operator can accurately read the lesion length and the cavity diameter at the lesion location, effectively solving the current problem of inaccurate judgment of the tracheal diameter and lesion length at the lesion location based on endoscopy.

[0048] When measuring the lesion length and cavity diameter at the lesion location in this embodiment, first, the length and opening size of the measuring component in the natural state are L1 and L2 respectively, and the push rod 1 is used to drive the measuring component to extend into the lesion location. At this time, the lesion length is measured, and the push handle 2 is pushed to slide on the push rod 1 until the end of the measuring component just moves out of the lesion location. At this time, the length indicator head 22 of the record handle 2 is recorded at the indicated position of the length scale bar 11 to obtain the lesion length L3 at the lesion location.

[0049] After the lesion length measurement is completed, the cavity diameter measurement at the lesion location is started. At this time, the amplitude indicator head 8 is pulled. Since the amplitude indicator head 8 is fixedly connected to the opening width measuring tube 6, and the opening width measuring tube 6 is fixedly connected to the measuring component, the measuring component abuts against the end of the length feed tube 7. Pulling the amplitude indicator head 8 will cause the measuring component to be under pressure, and the length L1 of the measuring component gradually decreases, and the size of the opening width L2 gradually increases until the measuring component contacts the cavity diameter at the lesion location. At this time, the indicated position of the amplitude indicator head 8 at the amplitude scale bar 21 is read to obtain the cavity diameter at the lesion location.

[0050] In this embodiment, the size of the opening L2 of the measuring component corresponds to the position where the amplitude indicating head 8 points to the amplitude scale bar 21. This is a prior art and will not be described in detail here.

[0051] Specifically, in this embodiment, Figure 1 、 Figure 2 、 Figure 5 As shown, it also includes an outer sheath tube 3 that is sleeved on the length feed tube 7 and slidably connected thereto, and the outer sheath tube 3 is fixedly connected to the push rod 1. By arranging the outer sheath tube 3, the length feed tube 7 can be protected.

[0052] Specifically, in this embodiment, Figures 1 to 3 As shown, the measuring assembly includes a first connecting tube 5 and a second connecting tube 10, and at least two elastic measuring members 4;

[0053] The measuring member 4 is in a curved or bent shape, and the concave sides of the measuring member 4 are all arranged toward the open-width measuring tube 6;

[0054] The two ends of the measuring piece 4 are respectively fixed in the first connecting tube 5 and the second connecting tube 10. The first connecting tube 5 is fixedly connected to the opening measuring tube 6, and the second connecting tube 10 abuts against the end of the length feed tube 7. In this embodiment, the first connecting tube 5 and the second connecting tube 10 serve to fix multiple measuring pieces 4. The measuring piece 4 in this embodiment has a bent shape in its natural state and a curved shape in the pressurized state when measuring the cavity diameter.

[0055] Specifically, in this embodiment, the measuring member 4 is a steel wire having a circular or flat cross-section. In this embodiment, the measuring member 4 has a circular cross-section. In some embodiments, the measuring member 4 may also have a flat cross-section or other shapes, which are not described here. In this embodiment, the measuring member 4 is made of steel wire to ensure strength. Alternatively, other materials such as memory alloys may be used as needed.

[0056] Specifically, in this embodiment, two or more measuring pieces 4 are evenly distributed along the circumference of the open-width measuring tube 6, and the overall shape of the two or more measuring pieces 4 is olive-shaped. In this embodiment, the number of measuring pieces 4 is about 4 to 6, and technicians can also set it to 2, 3, 8, 10, etc. according to needs. No examples are given here.

[0057] Specifically, in this embodiment, the first connecting tube 5 and the second connecting tube 10 are fixedly connected to the measuring member 4 by welding or crimping.

[0058] Specifically, in this embodiment, Figure 1 and Figure 7 As shown, the push rod 1 is also provided with a first sliding groove 12 which is parallel to and close to the length scale bar 11, and a length marking head 9 which is slidably connected thereto is provided in the first sliding groove 12. By providing the first sliding groove 12 on the push rod 1 and providing the length marking head 9 in the first sliding groove 12, after the handle 2 returns to the lesion position, the length marking head 9 can still indicate the lesion length and remember the lesion length, thereby avoiding the operator from making a mistake in remembering the lesion.

[0059] Specifically, in this embodiment, the handle 2 is further provided with a second sliding groove 211 arranged parallel to and close to the amplitude scale bar 21;

[0060] The amplitude indicating head 8 is arranged in the second sliding groove 211 and is slidably connected thereto. When measuring the cavity diameter at the lesion location, the amplitude indicating head 8 can be moved to slide in the second sliding groove 211 until the measuring component is pressed against the inner wall of the cavity at the lesion location. The cavity diameter can be obtained based on the indicated position of the amplitude indicating head 8 on the amplitude scale bar 21.

[0061] Specifically, in this embodiment, Figure 6 As shown, the handle 2 is provided with a feed tube fixing head 23 , and the feed tube fixing head 23 is provided with a first mounting hole 231 . The length feed tube 7 is located in the first mounting hole 231 and fixedly connected thereto.

[0062] Specifically, in this embodiment, Figure 8 As shown, the end of the amplitude indicating head 8 away from the second sliding slot 211 is provided with a second mounting hole 801;

[0063] The width measuring tube 6 is located in the second mounting hole 801 and is fixedly connected thereto.

[0064] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will be able to make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
