[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figure 1-2 This utility model provides a technical solution: a reciprocating oscillating file: including an inner blade 1, an outer blade 2 at one end of the inner blade 1, an outer handle 3 at one end of the outer blade 2, an inner handle 4 in the inner cavity of the outer handle 3, a spring 5 on one side of the inner handle 4, a buckle 6 on one side of the outer handle 3, and a power interface 7 in the inner cavity of the buckle 6.

[0018] Among them, a grinding head 1.1 is provided on one side of the inner tool bar 1, and a flushing channel 1.2 is provided in the inner cavity of the inner tool bar 1.

[0019] In this embodiment, the power interface 7 is the power supply device for the file. Under the action of the spring 5, the cam moves, driving the inner blade shank 1 to reciprocate. The spring 5 compresses the inner blade handle 4 and the latch 6, allowing tissue grinding to be performed through the grinding head 1.1 of the inner blade handle 1. The inner cavity of the inner blade handle 1 has a transversely opened flushing channel 1.2, which facilitates flushing of the joint cavity and tissue debris during surgery.

[0020] Among them, an outer tool cam 2.1 is provided on one side of the outer tool holder 2.

[0021] Among them, an inner cam 4.1 is provided on one side of the inner shank 4, and a square key 4.2 is provided on one side of the inner shank 4.

[0022] In this embodiment, the inner tool cam 4.1 in the inner tool holder 4 contacts the outer tool cam 2.1 in the outer tool bar 2. Under the action of the spring force 5, the cam moves, driving the inner tool bar 1 to reciprocate. The power output is converted from axial rotation to axial extension and retraction.

[0023] The outer tool holder 3 has a retaining hole 3.1 in its inner cavity.

[0024] Among them, the buckle 6 has a locking key 6.1 on one side.

[0025] In this embodiment, the inner cavity of the outer tool holder 3 has two locking holes 3.1 that are on the same vertical line. The side of the buckle 6 is fixed with two locking keys 6.1 that are also on the same vertical line. The locking holes 3.1 and the locking keys 6.1 are on the same horizontal line. By using the locking keys 6.1 and the locking holes 3.1 together, the buckle 6 can be fixed to one side of the outer tool holder 3.

[0026] The power interface 7 has a square groove 7.1 in its inner cavity and a flushing channel 7.2 in its inner cavity.

[0027] In this embodiment, the power interface 7 is designed with a flushing channel 7.2, and the inner blade 1 is designed with a flushing channel 1.2. The entire reciprocating grinding file has interconnected flushing channels, which facilitates flushing of the joint cavity and tissue debris during surgery.

[0028] Working principle: The grinding file is connected to the power device through the power interface 7 at the tail end; the power device outputs rotary power, and the power interface 7 drives the inner handle 4 and the key 4.2 through the square groove 7.1, causing the inner handle 4 to rotate; the spring 5 is compressed between the inner handle 4 and the latch 6; the inner cam 4.1 in the inner handle 4 contacts the outer cam 2.1 of the outer handle 2. Under the action of the spring force 5, the cam moves, driving the inner handle 1 to reciprocate, and the power output changes from axial rotation to axial extension; the grinding head 1.1 of the inner handle 1 is used for tissue grinding. The inner handle 1 is designed with a 1.2 irrigation channel, and the power interface 7 is designed with a 7.2 irrigation channel. The irrigation channels of the entire reciprocating grinding file are connected, which is convenient for rinsing the joint cavity and tissue debris during surgery.
