Preferably, as shown in fig. 1, 3 and 4, the front end of the shank is provided with two blade mounting portions 2, and as shown in fig. 4, the blade groove 21 is located in the middle of the blade mounting portions 2. Further preferably, as shown in fig. 3, the handle is symmetrical, the two blade mounting portions 2 are also symmetrically arranged, and adjacent sides thereof can be fixedly connected together, that is, the structure between the two blade grooves 21 can be an integral body, so that the strength of the blade mounting portions 2 is increased, and the manufacturing is easy. The distance between the two blades 4 is preferably 0.6 to 1.0mm.
A slidable device is added between the two blade mounting parts, so that the distance between the two blades can be adjusted, and the application range of the scalpel is wider. The sliding device can be used in the prior art. Preferably, at least one blade mounting portion 2 is provided at the front end of the handle by an adjusting member and is movable in a direction perpendicular to the blades 4 with respect to the other blade mounting portion 2, and the distance between the two blades 4 is adjustable by the adjusting member to change the width of the cut tissue according to actual needs.
In a preferred embodiment, the adjusting member includes a screw 22 and a nut 23, the axis of the screw 22 is perpendicular to the blade 4, at least one blade mounting portion 2 is sleeved on the screw 22, the nut 23 is meshed with the screw 22, and can convert rotation into movement along the axis direction of the screw 22, so as to drive the blade mounting portion 2 to move along the direction perpendicular to the blade 4.
Taking the example that two blade mounting portions 2 are provided at the front end of the cutter handle, preferably, as shown in fig. 6 (fig. 6 omits the hand-held portion of the cutter handle), one blade mounting portion 2 is fixedly provided at the front end of the cutter handle, the rear end of the other blade mounting portion 2 is located in a sliding groove at the front end of the cutter handle, and the sliding groove is parallel to the axis of the screw 22 for preventing the blade mounting portion 2 from shaking during the adjustment and movement. Of course, a sliding groove can be formed in the rear end of the blade mounting portion 2, a sliding rail is arranged at the front end of the cutter handle, and the blade mounting portion 2 is limited through cooperation of the sliding groove and the sliding rail, so that shaking of the cutter is prevented. The blade mounting part 2 is provided with a through hole, the nut 23 is arranged in the through hole and is contacted with the blade mounting part 2, and the blade mounting part 2 can be driven to move by rotating the nut 23.

Preferably, as shown in fig. 1 to 4, the supporting structure 3 is disposed at the front end of the hand-holding portion 1 and is close to the blade 4, that is, the supporting point of the supporting structure 3 is close to the rear end of the blade 4, when in use, the supporting structure 3 can not only support the blade 4 to keep a vertical state, but also does not affect the hand-held scalpel, thereby being convenient for operation, and not disturbing the replacement of the blade 4, and being convenient for use.
Preferably, the minimum distance from the support points of the first and second supports, which contact the tissue to be cut on both sides of the shank, to the blade 4 is in the range of 10-25 mm, i.e. the distance from the support points on both sides to the closest perpendicular to the blade 4 is in the range of 10-25 mm. Too close a supporting point of the supporting structure to the blade 4 is unfavorable for supporting, the blade 4 may not be ensured to be perpendicular to the tissue, and too far a distance may cause the volume of the scalpel to be too large, so that the flexibility is poor, and the operator is disturbed.
The first support piece and the second support piece can be support frames, the support frames are stable, but the support frames are rubbed with tissues during cutting, and operation can be affected. Preferably, as shown in fig. 1 to 3, the first supporting member and the second supporting member each comprise an axle 31 and a travelling wheel 32, the axes of the two axles 31 are perpendicular to the blade 4, and the two axles 31 are symmetrically arranged at equal heights on two sides of the cutter handle. The two travelling wheels 32 are the same in size, are respectively detachably sleeved on the corresponding wheel shafts 31 on the two sides of the cutter handle, and can rotate relative to the cutter handle. During the cutting process, the travelling wheel 32 rotates to continuously support the blade 4 with small resistance, so that the cutting process is smoother. If both wheel shafts 31 are fixed to the handle, the travelling wheel 32 needs to rotate relative to the wheel shafts 31. If two wheel shafts 31 pass through the tool handle to be connected, the wheel shafts 31 can rotate synchronously with the travelling wheels 32. The specific values of the diameters of the two road wheels 32 may be selected according to the height to be supported.
It is further preferred that the road wheels 32 are rotatably sleeved on the wheel axle 31 by means of bearings, i.e. that the road wheels 32 rotate relative to the wheel axle 31. The first supporting piece and the second supporting piece further comprise bearing check rings, the bearing check rings are sleeved on the wheel shaft 31 and located on the outer side of the bearing, and the bearing check rings are used for preventing the bearing from falling off from the wheel shaft 31.
Preferably, for conveniently adjusting the supporting height of the supporting structure 3, a plurality of adjusting grooves 33 are correspondingly arranged on two sides of the knife handle, the adjusting grooves 33 on two sides of the row are correspondingly arranged in pairs, the adjusting grooves 33 on the same side are correspondingly arranged at different mounting heights, when the supporting structure 3 is in contact with tissues at different mounting heights, the hanging heights of the knife handles at the mounting positions are different, the tips of the knife edges can cut into the tissues at different angles, for the same supporting structure 3, the smaller the mounting heights are, the closer the knife handles are to the edges of the knife handles, the larger the hanging heights of the knife handles at the mounting positions are, and the closer the cutting angles of the tips of the knife edges are to be vertical.
In a preferred embodiment, as shown in fig. 7, a plurality of adjusting grooves 33 are uniformly arranged longitudinally on the same side of the handle, one side of each adjusting groove 33 is communicated, after the wheel axle 31 is installed in the adjusting groove 33, the wheel axle 31 can be directly moved out of the adjusting groove 33 under one installation height during use, and the supporting height of the supporting structure 3 can be adjusted without dismounting the travelling wheel 32 by moving the communicated part to the adjusting groove 33 under the other installation height. The adjusting grooves 33 on two sides of the cutter handle can be communicated or not, if the adjusting grooves 33 on two sides of the cutter handle are communicated, the two wheel shafts 31 are connected into a whole through the cutter handle, and then the first supporting pieces and the second supporting pieces on two sides can be adjusted simultaneously, so that the adjustment is convenient.
