Description
Technical field:
This utility model relates to field of medical appliances, is specifically related to a kind of adjustable operation cutter.
Background technology:
At present, common scalpel is used in major part hospital, utilization is connected together, and easily throws off and drops, can be retained in patient body during use, there is malpractice, unnecessary injury is brought to patient, and some plug-type scalpels, also adjustable length, but be all that user rule of thumb regulates, the precision of adjustment is inaccurate.
Utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency and provides a kind of and regulate the accurate adjustable operation cutter of cutter hub length, can utilize the fine adjustment that the cooperation of fixation hook and holddown groove realizes in the length of cutter head.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of adjustable operation cutter, comprise handle of a knife and blade, described blade is arranged on one end of handle of a knife, it is characterized in that, described blade comprises blade body, raised line and fixation hook composition, described two raised lines are symmetricly set on one end of blade body, and be provided with fixation hook above described blade body, the upper surface of described fixation hook and blade body is hinged; One end of described handle of a knife is provided with a chute, and described raised line coordinates with chute, is provided with multiple holddown groove above described handle of a knife.
As preferably, described handle of a knife is evenly provided with multiple tread plate.
As preferably, the width of described holddown groove is set to 2mm ~ 5mm.
As preferably, described art chute designs wedgewise groove.
The beneficial effects of the utility model are: this utility model structure is simple, easy to use, can the front and back position of fine adjustment blade as required, and blade body and handle of a knife are not easy slippage, can improve the precision of operation, more allowing blade replacement is quick, blades fit is firm, and can not drop phenomenon, stable performance, bring convenience to medical worker, be easy to promote the use of.
Accompanying drawing illustrates:
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is the partial cutaway schematic diagram of handle of a knife;
Fig. 3 is the schematic perspective view of blade;
In figure: 1, handle of a knife; 1.1, chute; 1.2, tread plate; 1.3, holddown groove; 2, blade; 2.1, blade body; 2.2, raised line; 2.3, fixation hook.
Detailed description of the invention:
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
As shown in Figure 1, a kind of adjustable operation cutter, comprise handle of a knife 1 and blade 2, described blade 2 is arranged on one end of handle of a knife 1, as shown in Figure 3, described blade 2 comprises blade body 2.1, raised line 2.2 and fixation hook 2.3 and forms, and described two raised lines 2.2 are symmetricly set on one end of blade body 2.1, be provided with fixation hook 2.3 above described blade body 2.1, the upper surface of described fixation hook and blade body is hinged; As shown in Figure 2, one end of described handle of a knife 1 is provided with a chute 1.1, and described raised line 2.2 coordinates with chute 1.1, is provided with multiple holddown groove 1.3 above described handle of a knife 1.Described handle of a knife 1 is evenly provided with multiple tread plate 1.2.The width of described holddown groove 1.3 is set to 2mm ~ 5mm.Described chute 1.1 is designed to wedge-shaped slot.
During use, raised line 2.2 on blade 2 is inserted in chute 1.1, because chute 1.1 is wedge-shaped slot, described engaging is more firm, then hook in holddown groove 1.3 by fixation hook 2.3, the adjustable blade body degree of depth of inserting wedge groove and fixation hook 2.3 with which holddown groove 1.3 hook mutually and get as required, handle of a knife are provided with tread plate 1.2, effectively can prevent the slippage of scalpel, more stable during use.This utility model structure is simple, easy to use, can the front and back position of adjustable blade as required, can improve the precision of operation, more allowing blade replacement is quick, and blades fit is firm, and can not drop phenomenon, stable performance, brings convenience to medical worker, is easy to promote the use of.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
