[0021] The present invention provides a nerve conduit cleaning tool. The technical solution of the present invention is described in detail below with reference to the accompanying drawings to make it easier to understand and grasp.

[0022] Example 1

[0023] refer to Figure 1 - Figure 3 , a nerve catheter cleaning tool, comprising:

[0024] Two relatively parallel fixed bars 4; a plurality of position limiting guide holes are relatively arranged on the two fixed bars 4;

[0025] Two parallel first fixing rods 6 and second fixing rods 7, the two ends of the first fixing rod 6 are respectively fixedly connected to the first ends of the two fixing bars 4, and the two ends of the second fixing rod 7 are respectively fixedly connected to the second ends of the two fixing bars 4;

[0026] Multiple elastically deformable support rods 2 are arranged in one-to-one correspondence with multiple limiting guide holes. One end of the support rod 2 is inserted into the limiting guide hole of a fixing bar 4, and the other end is inserted into the limiting guide hole of another fixing bar 4.

[0027] In this embodiment, a plurality of support rods 2 are arranged in parallel and have the same length.

[0028] The length of the support rod 2 is greater than the distance between the two fixing bars 4 .

[0029] Preferably, the support rod 2 is a stainless steel rod with a slight bending property, and both ends are respectively inserted into the limiting guide holes of the fixing bars 4 on both sides.

[0030] In this embodiment, the length A of the support rod 2 is 425 mm, the distance B between the two arc end points of the bent support rod 2 is 420 mm, and the dimensional difference C between the length of the arc end points of the bent support rod 2 and the length of the support rod 2 in the normal state is 5 mm.

[0031] In this embodiment, the two fixing bars 4 are fixedly connected to the first fixing rod 6 and the second fixing rod 7 through the fixing assembly 3 .

[0032] Specifically, the fixing assembly 3 includes screws, washers and spring washers. The ends of the first fixing rod 6 and the second fixing rod 7 are provided with internal threads, and fixing holes are provided at both ends of the fixing bar 4. The screws are threadedly connected to the internal threads of the first fixing rod 6 / second fixing rod 7 through the washers, spring washers and fixing holes in sequence.

[0033] In this embodiment, each fixing bar 4 is provided with 20 limiting guide holes, corresponding to 20 support rods 2 , and each support rod 2 is passed through 6 nerve guide tubes.

[0034] The method of using the nerve conduit cleaning tool provided in this embodiment is as follows:

[0035] Insert the six nerve guides into the support rod 2 (stainless steel rod) in turn, and then insert the two ends of the support rod 2 (stainless steel rod) into the limiting guide holes of the fixing bars 4 on both sides (because the stainless steel rod has some bending properties, it is stuck in the limiting guide holes of the fixing bars 4 on both sides) so that the support rod 2 (stainless steel rod) is completely fixed in the limiting guide holes of the fixing bars 4; after cleaning is completed, because the support rod 2 (stainless steel rod) has some bending properties, take out the support rod 2 from the limiting guide hole and remove the six nerve guides in turn.

[0036] After the above-mentioned process of tube insertion and cleaning, the nerve conduit can always remain in a free state without being flattened, floating or bent, and the yield rate is high.

[0037] Example 2

[0038] In order to increase the cleaning quantity, this embodiment makes further arrangements based on embodiment 1.

[0039] In this embodiment, positioning holes are provided at both ends of the fixing strip in the length direction, and positioning pins 5 are provided in the positioning holes. The positioning pins 5 are used for positioning and connecting a plurality of the nerve conduit cleaning jigs when they are stacked.

[0040] In order to increase the number of nerve conduits cleaned, six nerve conduit cleaning jigs can be stacked and placed in a cleaning tank for cleaning, and the fixing bars 4 between two adjacent nerve conduit cleaning jigs are positioned and connected by positioning pins 5.

[0041] More specifically, the positioning pins 5 of the fixing strip 4 located between the lower nerve conduit cleaning jigs are inserted into the positioning holes of the fixing strip 4 located between the upper nerve conduit cleaning jigs.

[0042] The above fully describes the technical solution of the present invention. It should be noted that the specific implementation methods of the present invention are not limited to the above description. All technical solutions formed by ordinary technicians in this field using equivalent or equivalent transformations in structure, method or function based on the spirit of the present invention fall within the scope of protection of the present invention.
