Abstract
The invention discloses a small-sized cutting scalpel, which comprises a circular scalpel handle, wherein a mounting groove is formed in the top surface of the left part of the circular scalpel handle, a cutting blade is placed on the top surface of the mounting groove, a through hole is formed in the middle of the cutting blade, a screw rod of a fixing screw is inserted and sleeved in the through hole, the bottom end of the screw rod of the fixing screw is in threaded connection with a threaded hole formed in the bottom surface of the mounting groove, and the cutting edge of the cutting blade extends out of the mounting groove. The novel small-sized cutting blade is small in size, suitable for outpatient small-sized cutting operations, convenient to install and disassemble and firm in fixing, and the cutting blade is fixed through the fixing screws.
Description
The technical field is as follows:
the invention relates to the technical field of medical equipment, in particular to a small-sized cutting scalpel.
Background art:
the existing surgical knife for hospitals generally comprises a knife handle and a blade, wherein a clamping groove is formed on the blade, the length of the knife handle is long, the knife handle is generally required to be held by the whole hand during holding, and is not suitable for small-part cutting operation, particularly in outpatient service operation, the knife only needs to be cut by a small part, and the two long-handle surgical knives are not suitable;
in addition, the blade of the existing surgical knife is directly clamped on the lug boss, and the fixation is not firm.
The invention content is as follows:
the invention aims to overcome the defects of the prior art and provides a small-sized cutting scalpel which is small in size and suitable for outpatient small-sized cutting operation, and the cutting blade of the scalpel is fixed by a fixing screw, so that the scalpel is convenient to mount and dismount and is firm in fixation.
The technical solution of the invention is as follows:
the utility model provides a small-size cutting scalpel, includes circular handle of a knife, the left part top surface shaping of circular handle of a knife has mounting groove, and cutting blade has been placed to mounting groove's top surface, and cutting blade's middle part shaping has a through-hole, and the screw rod plug bush of fixed screw is in the through-hole, and the bottom spiro union of fixed screw's screw rod stretches out mounting groove in some spiro union holes of mounting groove's bottom surface shaping.
The front portion and the rear portion of the top surface of the mounting groove are both formed with protruding strips, the cutting blade plug bush is arranged between the two protruding strips, and the side wall of the cutting blade is tightly attached to the inner side wall of the corresponding protruding strip.
The screw rod of the fixing screw is inserted and sleeved with an elastic pressing pad, the cutting blade is clamped between the top surface of the mounting groove and the elastic pressing pad, and the rotating part of the fixing screw is pressed against the top surface of the elastic pressing pad.
A plurality of protruding anti-skidding parts are formed on the top surface of the right part of the circular cutter handle.
The bottom surface of the circular knife handle is an elliptical convex surface.
The top surface of the circular knife handle is an elliptical convex surface.
The invention has the beneficial effects that:
the novel small-sized cutting blade is small in size, suitable for outpatient small-sized cutting operations, convenient to install and disassemble and firm in fixing, and the cutting blade is fixed through the fixing screws.
Description of the drawings:
FIG. 1 is a schematic view of a partial structure of the present invention;
fig. 2 is a partial cross-sectional view of the present invention.
The specific implementation mode is as follows:
example (b): referring to fig. 1 to 2, a small-size cutting scalpel comprises a circular scalpel handle 10, a mounting groove 11 is formed in the top surface of the left portion of the circular scalpel handle 10, a cutting blade 20 is placed on the top surface of the mounting groove 11, a through hole 21 is formed in the middle of the cutting blade 20, a screw rod of a fixing screw 30 is inserted into the through hole 21, the bottom end of the screw rod of the fixing screw 30 is screwed in a screwed hole formed in the bottom surface of the mounting groove 11, and the blade of the cutting blade 20 extends out of the mounting groove 11.
Further, the front part and the rear part of the top surface of the mounting groove 11 are both formed with a protruding strip 12, the cutting blade 20 is inserted between the two protruding strips 12, and the side wall of the cutting blade 20 is tightly attached to the inner side wall of the corresponding protruding strip 12; the screw of the fixing screw 30 is inserted and sleeved with an elastic pressing pad 40, the cutting blade 20 is clamped between the top surface of the mounting groove 11 and the elastic pressing pad 40, and the rotating part of the fixing screw 30 is pressed against the top surface of the elastic pressing pad 40.
The top surface of the right part of the circular cutter handle 10 is provided with a plurality of convex anti-skid parts 13.
The bottom surface of the circular knife handle 10 is an elliptical convex surface.
The top surface of the circular knife handle 10 is an elliptical convex surface.
In the embodiment, the circular knife handle 10 is adopted, so that the volume is small, the circular knife handle is suitable for the use in the outpatient small incision surgery, and meanwhile, the cutting blade 20 is fixed by the fixing screw 30, so that the installation and the disassembly are convenient, and the cutting blade 20 is firmly fixed;
in this embodiment, it is between two protruding strips 12 through cutting blade 20 plug bush, and the inside wall of the protruding strip 12 that corresponds is hugged closely to cutting blade 20's lateral wall to can prevent it rotatory at the horizontal direction, and fixed through set screw 30, can prevent that cutting blade 20 from dropping, its simple to operate, fixed firm, effectual.
