Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution for a surgical tool with an adjustable blade angle: a surgical tool with an adjustable blade angle, comprising a handle 1, and also comprising: a blade 2, a blade being provided at the bottom of the blade 2; an angle adjustment component 3, the handle 1 and the blade 2 being connected via the angle adjustment component 3; the angle adjustment component 3 comprising an adjustment disk 31, a rotating hole 32 and a positioning hole 33 provided on the outer side of the adjustment disk 31, a rotating column 34 and a limiting block 35 provided on the outer side of the handle 1, an auxiliary hole 36 provided on the outer side of the handle 1, a moving hole 37 and a limiting groove 38 provided inside the handle 1, a positioning column 39 provided inside the moving hole 37, a connecting block 310 connected to one side of the positioning column 39, and a supporting spring 311 provided on one side of the connecting block 310.

[0025] Among them, the number of anti-skid grooves 4 is several groups and distributed in an array, and the thickness of the anti-skid grooves 4 is less than the thickness of the handle 1, which is beneficial to increase the friction of the fingertips through several groups of anti-skid grooves 4 when holding the handle 1, thereby achieving an anti-skid effect.

[0026] In addition, the adjusting disk 31 and the cutter head 2 are fixedly connected. The adjusting disk 31 is a cylindrical structure. The rotating hole 32 runs through the middle of the adjusting disk 31, and the rotating hole 32 is matched with the rotating column 34. The rotating column 34 and the tool handle 1 are fixedly connected. The limit block 35 and the rotating column 34 are fixedly connected. The diameter of the limit block 35 is larger than the diameter of the rotating hole 32. The number of positioning holes 33 is several groups and is distributed in an array. The apertures of the auxiliary holes 36 and the movable holes 37 are equal. The movable holes 37 are connected with the limiting grooves 38. The end of the positioning column 39 is an arc structure. The positioning column 39 is matched with the movable hole 37, the positioning hole 33 and the auxiliary hole 36. The connecting block 310 and the positioning column 39 are fixedly connected. The two sides of the support spring 311 are respectively connected with the connecting block 310 and the limiting groove 38, which is conducive to the angle rotation adjustment of the cutter head 2.

[0027] During operation of the surgical knife with adjustable blade angle, the user holds the handle 1 and uses the anti-skid groove 4 to prevent slipping. At the same time, the angle of the blade 2 can be adjusted through the angle adjustment component 3 to facilitate subsequent cutting operations of the blade 2.

[0028] The user can adjust the angle of the cutter head 2 by pressing the positioning post 39 to move the positioning post 39 along the auxiliary hole 36, the positioning hole 33 and the movable hole 37, so that the positioning post 39 drives the connecting block 310 to move along the inner part of the limiting groove 38, and the supporting spring 311 is compressed until the positioning post 39 is compressed to the inner part of the movable hole 37 and then disengages from the inner part of the positioning hole 33, and then rotates the adjusting disk 31 to make the rotating hole 32 rotate along the outer side of the rotating post 34, and the limiting block 35 is used to prevent the rotating post 34 from disengaging from the rotating hole 32, and then the cutter head 2 is rotated and adjusted to the appropriate position, and the user releases the finger, and the positioning post 39 rebounds under the elastic potential energy of the supporting spring 311 and is inserted into the corresponding positioning hole 33, and then the adjusting disk 31 is fixed to prevent the cutter head 2 from being displaced during the force application process, thereby improving the stability, the structure is simple, the operation is convenient, and the practicality of the tool is improved.
