[0002] Minimally invasive interventional therapy is a medical technology that uses specific puncture needles, guide wires or catheters under the guidance of images to accurately reach the lesion site for diagnosis and treatment without cutting into human tissue. Minimally invasive interventional therapy is increasingly favored by patients because of its small trauma, confirmed efficacy and no side effects.
[0003] A hypotube is a long piece of metal with micro-engineering properties throughout its entire tube. It is an important component in minimally invasive interventional therapy. In minimally invasive interventional therapy, related instruments are guided to the lesion site. However, during the guiding process, if the lesion site is severely blocked, the hypotube needs to be bent in a certain direction at a certain angle to smoothly reach the specific site. However, existing hypotubes are generally cut equidistantly on opposite sides, so that the hypotube can only bend to the left or right. Utility Model Content

[0028] Aiming at the problem that the existing hypotube can only bend to the left or to the right, a hypotube which can bend in any direction along the circumference of the tube body is disclosed.
[0029] The utility model discloses a hypotube for endoscope, comprising a tube body 1, Figure 1-2The tube body 1 is a hollow structure. Preferably, the tube body 1 is a cylindrical structure with a hollow interior. The tube body 1 includes a distal area 12 and a proximal area 13. The distal area 12 is provided with a plurality of pairs of cutting groove groups 11 extending along its circumference, and the plurality of pairs of cutting groove groups 11 provided in the distal area 12 are evenly distributed along the axial direction of the tube body 1; the proximal area 13 is provided with a plurality of pairs of cutting groove groups 11 extending along its circumference, and the plurality of pairs of cutting groove groups 11 provided in the proximal area 13 are evenly distributed along the axial direction of the tube body 1, and the distance between adjacent cutting groove groups 11 in the distal area 12 is smaller than the distance between adjacent cutting groove groups 11 in the proximal area 13. This design makes the hardness of the distal area 12 of the sea wave tube smaller than that of the proximal area 13, that is, the distal area 12 and the proximal area 13 of the sea wave tube have different hardnesses and multiple curvatures. Different curvatures can adapt to different application scenarios, thereby increasing its scope of application.
[0030] It can be understood that the cutting grooves in the cutting groove group 11 are cut in an arc shape along the circumference of the tube body 1, and the angle of the cutting arc is related to the required bending angle and the required hardness of the sea wave tube. The smaller the cutting arc, the smaller the angle at which the sea wave tube can be bent, and the harder the sea wave tube as a whole.
[0031] As an embodiment of the utility model, each cutting groove group 11 includes a first cutting groove 111 and a second cutting groove 112. Preferably, the cutting gap between the first cutting groove 111 and the second cutting groove 112 is 0-10 mm, the first cutting groove 111 and the second cutting groove 112 are symmetrical relative to the central axis of the tube body 1, and the first cutting groove 111 and the second cutting groove 112 are not connected at both ends to form a slot 113. Any slot 113 is rotated a certain angle with the slot 113 adjacent to it relative to the central axis of the tube body 1. Preferably, Selectively, along the direction from the distal area 12 to the proximal area 13 of the tube body 1, every 6 cutting groove groups 11 constitute a unit, and the first slot 113 in each unit is relatively positioned, and the other slots 113 in each unit are rotated 30° relative to the central axis of the tube body 1 than the previous slot 113. The 6 cutting groove groups 11 just circulate along the circumference of the tube body 1 for one cycle, which can not only ensure the supporting performance of the sea wave tube, but also enable the sea wave tube to bend in any direction along the circumference of the tube body, thereby improving the degree of freedom of the sea wave tube, and the process is simple and easy to implement.
[0032] As a preferred embodiment of the present invention, the distance between two adjacent cutting groove groups 11 is 0-100 mm.
[0033] The hypotube for endoscope disclosed by the utility model can be bent in any direction along the circumference of the tube body, thereby improving the degree of freedom of the hypotube, having a simple process, being easy to implement, and being able to ensure the supporting performance of the hypotube.
