Embodiment 1

[0039] Such as image 3 As shown, the medical measuring device 100 of the present invention includes a guide wire 10 , a measuring tube assembly 20 and a catheter 30 .

[0040] Figure 4 A schematic structural view of the guide wire 10 is shown, and the guide wire 10 includes a handle 11 , a main body section 12 and a guide section 13 .

[0041] The proximal end of the guide wire 10 is provided with a handle 11 that is convenient for pushing and holding, and the distal end of the handle 11 is provided with a section of external thread 111, which can form a threaded connection with the internal thread of the casing 22 in the measuring tube assembly 20, so that the guide wire 10 can drive the cannula 22 to move on the measuring tube 21 when moving to the bronchi waiting for the measuring body. It should be noted that the threaded connection between the handle 11 and the sleeve 22 is only a preferred embodiment, and it is not a limitation on the connection method between the ha...

Embodiment 2

[0063] It should be noted that the function of the catheter 30 in the first embodiment is mainly to implant the lung volume-reducing elastic implant into the bronchus 300, and the catheter 30 has little effect when the medical measuring device 100 measures the length of the diseased bronchus 300 .

[0064] Therefore, in the second embodiment, the medical measuring device 100 may only include the guide wire 10 and the measuring tube assembly 20 . The structure and working principle of the guide wire 10 and the measuring tube assembly 20 of the medical measuring device 100 are similar to those of the first embodiment, and will not be repeated here.

Abstract

The invention relates to a medical measuring device and a lung volume reduction system. The medical measuring device comprises a measuring tube assembly and a guide wire capable of movably penetrating through the measuring tube assembly, the measuring tube assembly comprises a measuring tube and a sleeve nested outside the measuring tube, a measuring scale section is arranged on the outer surface of the measuring tube, and when the guide wire moves, the sleeve is driven to slide on the measuring tube. The medical measuring device has the advantages that the length of the bronchial tube can be measured more conveniently and more precisely, the length of the bronchial tube can be measured without arranging a plurality of metal developing marks at the far end of the guide wire, the risk that the metal developing marks fall into organs is avoided, and the operability and the safety of the medical measuring device are improved.

Description

technical field [0001] The invention relates to the technical field of interventional medical equipment, in particular to a medical measuring device and a lung volume reduction system. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] In the current treatment of emphysema, the lung volume reduction elastic coil is implanted as an implant into the lung lesion of the human body. The lung volume reduction elastic coil is designed and made of nickel-titanium memory alloy wire, which can undergo elastic deformation under the action of external force. Under the constraints of the loading system (sheath), the lung volume-reducing elastic coil can be implanted into the lungs in a straight strip through the working channel of the bronchoscope. Constraint, restore the deformation into a natural shape (that is, the shape when it is not subjected to external force), and at the sa...
