Description
Technical field
Precisely adjustable surgical knife belongs to medical instruments field to a kind of depth of cut of the present invention, and more particularly to scalpel exists
Depth when cutting skin is precisely adjustable.
Background technology
Existing surgical knife mostly only has blade and handle of a knife composition, in use the depth of scalpel cutting skin
Depth of cut is rule of thumb controlled with sensation by operating doctor completely, is a kind of dangerous challenge for trainee, for
Bigger injury is can suffer from for patient, even veteran doctor can also occur accident, a kind of depth of cut essence once in a while
The surgical knife that will definitely be controlled still belongs to blank.
The content of the invention
Precisely adjustable surgical knife overcomes drawbacks described above to a kind of depth of cut of the present invention, by common surgical knife
By improving, support is mounted with behind cutting blade, the later half position of support has been arranged to bar shaped bolt, set behind bolt
Graduated scale is put, the both sides of cutting blade are respectively arranged a piece of identical banking stop and are connected with blade, and the inside of blade is equipped with branch
Frame, the latter half of blade are mounted with intermeshing with bar shaped bolt adjusting nut and locking nut, and thus structure can essence
The depth of cut of quasi- control knife blade.
A kind of accurate adjustable surgical knife of depth of cut：Including cutting blade 1, banking stop 2, blade 3, adjusting nut 4,
Locking nut 5, graduated scale 6, support 7, bar shaped bolt 8, cutting blade is connected with support, support and bar shaped bolt connection, bar shaped
Bolt is connected with graduated scale, and banking stop is connected with blade, and adjusting nut, locking nut and blade connect, cutting blade, support,
Bar shaped bolt, graduated scale are installed on the inside of blade.
Blade is cylindrical shape, and front end is mounted with two plate shapes similar to cutting blade and size identical banking stop, two side by side
Gap between piece banking stop is equal with the thickness of cutting blade, and the centre position of latter half is provided with what is be inwardly symmetrically recessed
Gap between two semicircle strips, two root long bars is equal with the thickness of bar shaped bolt, strip length and adjusting nut and
The overall length of locking nut is equal, adjusting nut and locking nut are installed on above strip.
Support is cylindrical shape, and front end is mounted with that dismountable cutting blade, blade are placed between two panels banking stop, after
End and the connection of the front end of bar shaped bolt, bolt are placed between two semicircle strips of blade, and the rear end of bar shaped bolt is connected to
Graduated scale, the length of graduated scale extend to the outside of blade end.
Beneficial effect：Existing surgical knife mostly only has blade and handle of a knife composition, and scalpel is cut in use
The depth of skin completely by operating doctor rule of thumb with feel to control depth of cut, improved surgical knife can be with
It is precisely controlled the depth of cut of knife blade.
Brief description of the drawings
Fig. 1 is a kind of front view of the accurate adjustable surgical knife of depth of cut.
Fig. 2 is banking stop, the schematic diagram of blade.
Fig. 3 is cutting blade, support, bar shaped bolt, the schematic diagram of graduated scale.
Fig. 4 is adjusting nut, the schematic diagram of locking nut.
Embodiment
Technical scheme is further illustrated in conjunction with accompanying drawing 1-4：
A kind of accurate adjustable surgical knife of depth of cut：Including cutting blade, banking stop, blade, adjusting nut, locking screw
Mother, graduated scale, support, bar shaped bolt, cutting blade are connected with support, support and bar shaped bolt connection, bar shaped bolt and scale
Chi is connected, and banking stop is connected with blade, and adjusting nut, locking nut and blade connect, cutting blade, support, bar shaped bolt, quarter
Degree chi is installed on the inside of blade；
Blade is cylindrical shape, and front end is mounted with that two plate shapes limit similar to cutting blade and size identical banking stop, two panels side by side
Gap between bit slice is equal with the thickness of cutting blade, and the centre position of latter half is provided with two be inwardly symmetrically recessed
Gap between semicircle strip, two root long bars is equal with the thickness of bar shaped bolt, strip length and adjusting nut and locking
The overall length of nut is equal, adjusting nut and locking nut are installed on above strip；
Support is cylindrical shape, and front end is mounted with that dismountable cutting blade, blade are placed between two panels banking stop, rear end with
The front end connection of bar shaped bolt, bolt are placed between two semicircle strips of blade, and the rear end of bar shaped bolt is connected to scale
Chi, the length of graduated scale extend to the outside of blade end.
According to a kind of above-mentioned depth of cut, precisely scalpel in use, is first placed in 120 by adjustable surgical knife
DEG C high temperature in sterilize 20min, place into medicinal alcohol soak it is stand-by, when patient need carry out surgical operation when, first confirm
The depth of cut of cutting part is needed, scalpel, rotating adjusting nut is taken out, examines the quarter for extending within out from blade
The scale of chi is spent, the scale that graduated scale is shown is exactly length, the i.e. depth of cut that cutting blade extends within out from banking stop,
Operator doctor can carefully cut out the depth of needs in affected part.
The conventional announcement of the present invention is the foregoing is only, any formal limitation not is made to the present invention；It is all to be familiar with sheet
The technical staff of industry in the range of without departing from technical scheme, implement techniques described above is made it is any equivalent
Adjustment, modification and differentiation of change etc., still fall within the protection domain of technical scheme.
