Description

Technical Field

[0001] The invention relates to a tearable expansion channel tube, belonging to the technical field of medical equipment. Background Art

[0002] Existing intracranial lesion surgeries require surgery on the lesion site through brain tissue. Existing channel tubes require an expander to expand the brain tissue first, and then insert the channel tube until the channel tube reaches the lesion site. However, this will cause damage to the brain tissue, and the scale size on the current channel tube is easily blocked, affecting the accuracy of the surgery. Summary of the invention

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a tearable expansion channel tube, which is a spiral tube type and can be expanded; the channel tube wall can be torn off along the axial direction; and the scale lines are annular scale lines.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a tearable expansion channel tube, the channel tube body is in a spiral tube shape and is transparent, and is formed by spiraling a plastic round tube with a single side wall broken along the axial direction. The spiral makes the outer diameter of the channel tube smaller, and reduces the damage to the brain tissue when penetrating into the brain tissue. The inner edge of the channel tube body is provided with a convex edge, the outer edge of the channel tube body is provided with a groove, the inner side of the outer edge of the channel tube body and the head, tail and middle of the outer wall of the channel tube body are provided with virtual connection points, a dotted line breakpoint is provided at a distance of one-third of the circumference of the channel tube body from the convex edge, and a dotted line breakpoint is provided at a distance of one-third of the circumference of the channel tube body from the groove, so that the channel tube can be torn off, and the outer wall of the channel tube body is provided with scale lines, the scale lines are annular and surround the outer wall of the channel tube body, the annular scale lines are solid lines of a certain length at the scale values, and the scale lines of other parts are dotted lines.

[0005] The beneficial effects of the present invention are as follows: when the present invention is used to perform intracranial lesion surgery, the channel tube expands in the brain tissue after reaching the lesion position, thereby reducing damage to the brain tissue; when the scale value is blocked by blood or the like, the annular scale line facilitates viewing of the size; the channel tube can be torn off, thereby facilitating surgical instruments to reach lesion positions at different depths, making the operation more convenient and reducing surgical risks.

[0013] like Figure 1-4 As shown, a tearable expansion channel tube, the channel tube body 1 is a spiral tube-shaped and transparent as a whole, and is formed by spiraling a plastic round tube with a single side wall broken along the axial direction, the inner edge of the channel tube body 1 is provided with a convex edge 2, the outer edge of the channel tube body 1 is provided with a groove 3, the inner side of the outer edge of the channel tube body 1 and the head, tail and middle of the outer wall of the channel tube body 1 are provided with virtual joints 4, a tearable part 6 is provided at a distance of one-third of the circumference of the channel tube body 1 from the convex edge 2, and a dotted line breakpoint 6 is provided at a distance of one-third of the circumference of the channel tube body 1 from the groove 3, so that the channel tube can be torn off, and scale lines 5 are provided on the outer wall of the channel tube body 1, and the scale lines 5 are annular and surround the outer wall of the channel tube body 1. The scale lines 5 are solid lines of a certain length at the scale value, and the scale lines 5 in other parts are dotted lines.

[0014] Specific operation method:

[0015] The channel tube body 1 is slowly inserted into the lesion in the brain tissue, and a dilator is used to penetrate into the channel tube body 1. As the plastic round tube is spiraled, plastic deformation occurs. The balloon is slowly expanded until the virtual contact 4 is disconnected. The channel tube body 1 will expand autonomously, but will not expand to the state where the convex edge 2 contacts the groove 3. It is necessary to continue to expand the balloon so that the convex edge 2 is embedded in the groove 3, remove the balloon dilator, and perform the operation.
