[0031] By setting blade 2 as curved, and slender than ordinary surgical knife, when carrying out keloid removal, blade 2 can be subcutaneous dissociation removal, can be more flexible to the removal of nodule tissue, and reduce the destruction of epidermis, so that the operation of user is more flexible and convenient, can improve the speed of operation to some extent.

[0032] Specifically, the side surface of handle 1 is provided with socket 3, blade 2 is inserted and assembled in socket 3, the inside of socket 3 is provided with clamping piece, for clamping locking blade 2.

[0033] Specifically, the clamping piece includes sliding rod 4 slidingly inserted in the inner wall of socket 3, the bottom end of sliding rod 4 is fixedly connected with two plug posts 5 through a gasket, and the top end of sliding rod 4 is of inclined surface structure;The outer side surface of handle 1 is slidingly connected with push sleeve 6 for pushing sliding rod 4 to move downward;Baffle 7 is fixedly connected to the middle part of sliding rod 4, and sliding cavity 8 is formed in the position of socket 3 relative to baffle 7, and spring is arranged in the position between baffle 7 and sliding cavity 8 in the middle part of sliding rod 4.

[0034] For the assembly of blade 2 and handle 1, such asFigure 3 and Figure 4 As shown, by inserting the blade 2 into the socket 3 and then pushing the push sleeve 6, the push sleeve 6 presses down on the top of the slide rod 4. As a result, the slide rod 4 drives the insert pins 5 to move down. The two insert pins 5 move down and squeeze the blade 2, thereby completing the assembly of the blade 2 and the handle 1. At the same time, when the slide rod 4 moves down, the spring will be compressed. When the push sleeve 6 moves away from the slide rod 4, the insert pins 5 will separate from the blade 2 under the action of the spring. Through this structural design, the disassembly and assembly of the blade 2 can be completed.

[0036] Specifically, the blade 2 has two limiting holes 9 on its side, and the insert pin 5 can be inserted into the limiting holes 9. With this design, when the insert pin 5 moves down, the two insert pins 5 can be inserted into the limiting holes 9. The insert pin 5 and the limiting holes 9 cooperate to limit the blade 2, which can ensure the stability of the blade 2 assembly.

[0037] Specifically, the push sleeve 6 has an inclined opening on its side for fitting snugly against the top of the slide rod 4. This design facilitates the push sleeve 6 to push the slide rod 4 downward.

[0038] Specifically, the push sleeve 6 is threaded with a fastening rod 10 on its side to fix the push sleeve 6. After the position of the push sleeve 6 is adjusted, the user can rotate the fastening rod 10 so that the bottom end of the fastening rod 10 contacts the tool holder 1, thereby completing the restriction of the push sleeve 6.

[0039] like Figure 3 As shown, a connecting hole is also provided on the blade 2 near the limiting hole 9. The shape and structure of this connecting hole can be inserted into the handle of an existing ordinary surgical knife on the market. Through this structural design, the blade 2 can be directly assembled with an existing surgical knife handle.
