The first cutter 21 and the second cutter 22 in this embodiment can be selected as surgical cutters according to needs, and can use cutters with the same function or cutters with different functions, which will not be described in detail here.

[0023] An opening 11 is provided at one end of the blade body 1 along its length direction, and an avoidance groove 12 is provided on the side wall of the blade body 1 along its length direction for the first tool 21 or the second tool 22 to rotate. The avoidance groove 12 extends to the opening 11, and the length of the avoidance groove 12 is greater than the length of the first tool 21 or the second tool 22. The first tool 21 and the second tool 22 are rotatably arranged in the avoidance groove 12 to facilitate the rotation and replacement of the first tool 21 or the second tool 22.

[0024] Furthermore, it also includes a locking member 3 for limiting the rotation of the first tool 21 and the second tool 22. The tool body 1 is symmetrically provided with two through holes 13 along the direction of the avoidance groove 12, and one of the through holes 13 passes through the side wall of the tool body 1, and the other through hole 13 does not pass through the side wall of the tool body 1, so that one end of the pin 23 (described in detail below) can be pressed against the side wall of the tool body 1. A pin 23 hinged to the through hole 13 is provided at the connection between the first tool 21 and the second tool 22. The locking member 3 is fixedly connected to one end of the pin 23 and is provided on the outside of the tool body 1, and the locking member 3 is tightly matched with the through hole 13. It is worth noting that the locking member 3 in this embodiment can be a bolt or other parts, as long as it can be tightly matched with the through hole 13. In this embodiment, when the tool is to be switched, the locking member 3 and the pin shaft 23 are pulled outward so that the locking member 3 and the through hole 13 are unlocked. At this time, the locking member can be rotated to switch the first tool 21 or the second tool 22. Of course, the press-and-rebound structure commonly used on the market can also be adopted, that is, the locking member 3 is pressed so that the locking member 3 pops outward and unlocks the through hole 13. When the tool is switched, the locking member 3 and the pin shaft 23 are pressed inward again so that the locking member 3 and the through hole 13 are tightly matched to lock the first tool 21 and the second tool 22. At this time, the first tool 21 and the second tool 22 will not move considerably.

[0025] Furthermore, a limiting block 24 is provided on the inner side of the pin shaft 23 corresponding to the through hole 13 to limit the pin shaft 23 from escaping from the through hole 13 .

[0026] Furthermore, a slide groove 14 for the locking member 3 and the pin 23 to move is provided on one side of the blade body 1 corresponding to the through hole 13, and the locking member 3 and the pin 23 drive the first tool 21 and the second tool 22 to move on the slide groove 14. Specifically, the slide groove 14 has a first positioning groove 141 for the first tool 21 or the second tool 22 to move in a retracted state and a second positioning groove 142 for the first tool 21 or the second tool 22 to move in an extended state, the first positioning groove 141 is arranged at an end away from the opening 11, and the second positioning groove 142 is arranged at an end close to the opening 11. When the locking member 3 moves to the first positioning groove 141, the first tool 21 and the second tool 22 retract into the inner cavity of the blade body 1; when the locking member 3 moves to the second positioning groove 142, the first tool 21 and the second tool 22 extend, and at this time, the first tool 21 or the second tool 22 extends out of the opening 11. Specifically, the above-mentioned through hole 13 is arranged at the end of the first positioning groove 141 or the second positioning groove 142, and the diameter of the through hole 13 is larger than the width of the first positioning groove 141 or the second positioning groove 142, and the lowest end of the through hole 13 is lower than the lowest end of the first positioning groove 141 or the second positioning groove 142, so as to facilitate the positioning of the pin shaft 23 or the locking member 3, and place the pin shaft 23 or the locking member 3 in the first positioning groove 141 or the second positioning groove 142 to move.

[0027] Preferably, a connecting groove 143 is further provided between the first positioning groove 141 and the second positioning groove 142. The first positioning groove 141, the second positioning groove 142 and the connecting groove 143 all penetrate the side wall of the blade body 1. The connecting groove 143 is provided along the length direction of the blade body 1. The first positioning groove 141 and the second positioning groove 142 are provided along the width direction of the blade body 1, and the two are parallel to each other. The locking member 3 is moved by hand from the first positioning groove 141 provided on the upper side to the connecting groove 143, and then the locking member 3 is moved downward to move the locking member 3 downward in the connecting groove 143 until the bottom of the locking member 3 fits with the bottom of the connecting groove 143, and then the locking member 3 is moved into the second positioning groove 142 of the lower layer, so that the first tool 21 or the second tool 22 is extended out of the opening 13 of the blade body 1.

[0028] Preferably, the widths of the connecting groove 143 , the first positioning groove 141 and the second positioning groove 142 are comparable, and are all larger than the diameter of the pin shaft 23 and smaller than the diameter of the locking member 3 .

[0029] Furthermore, the length of the connecting groove 143 is equal to or greater than the length of the first tool 21 or the second tool 22. When the locking member 3 (the first tool 21 or the second tool 22) is moved upward, the first tool 21 and the second tool 22 of this embodiment can be hidden in the tool body 1.

[0030] Furthermore, the outer surface of the blade body 1 is provided with an anti-slip structure (not shown in the figure).

[0031] The utility model also provides another embodiment, in which the blade body 1 is provided with openings 11 at both ends along its length direction, that is, a rotatable and movable first blade 21 and a second blade 22 can be provided at both ends, so as to facilitate replacement of surgical tools with different cutting edges during actual use.

[0032] The utility model also provides another embodiment, which also includes an extended handle 4, and both ends of the extended handle 4 are detachably connected to the knife body 1. Preferably, there is at least one extended handle 4, so as to achieve the length adjustment of the entire scalpel, which is convenient for medical staff to determine the length according to specific circumstances, and is more convenient in actual use; at the same time, the knife head and the knife holder can be disassembled and replaced, which is convenient for replacing surgical tools with different cutting edges during actual use. Tools with different cutting edges work differently, so that a scalpel can have multiple functions. The extended handle 4 is set to be truncated, and the cross-sectional size gradually becomes smaller along the direction of its length setting, which is convenient for holding.

[0033] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are as follows: the first tool 21 and the second tool 22 with the same or different functions are combined together, so that one tool can be used for two purposes, which is convenient for replacing surgical tools with different cutting edges during actual use. Tools with different cutting edges work differently, so that one scalpel can have multiple functions, which is more convenient in actual use; because the first tool 21 and the second tool 22 are compactly arranged in the inner cavity of the same knife body 1 in design, the knife body material is saved, the manufacturing cost is reduced, and it is convenient for people to carry; at the same time, a quick-release structure of the extended knife handle 4 and the knife body 1 is provided to facilitate the disassembly and replacement of the knife used for surgery, thereby avoiding the increase in the use cost caused by replacing the entire surgical tool due to damage or breakage of the cutting edge of the sharp blade, and can extend the service life of the surgical tool.
