Description
Technical field
The present invention relates to field of medical device, specially a kind of detachable multifunctional scalpel.
Background technique
Medical technology refers to that medical institutions and its medical worker for the purpose of diagnosing and treating disease, make disease and sentence
It is disconnected and eliminate disease, alleviate the state of an illness, palliate the agonizing sufferings, improving function, extending life, help patient gets well and that takes examines
Disconnected, remedy measures.Medical technology is divided into three classes：First kind medical technology refers to that safety, validity are definite, and medical institutions pass through
Routine Management can ensure that the technology of its safety, validity in clinical application.Second class medical technology refer to safety, effectively
Property is definite, is related to certain ethics problem or risk is higher, administrative department of public health should be controlled the medical technology of management.
The scalpel that surgeon uses in hospital divides blade and knife handle.Blade is disposably that knife handle is not.It is other
Instrument is also not disposably, but is all by autoclaved in each use.The usage mode of scalpel has：(1)
Bow formula is held, most common one kind holds knife mode, and actuating range is wide and flexible, is firmly related to entire upper limb, mainly in wrist, is used for
Longer skin incision and the incision of theca of rectus abdominis muscle etc.；(2) pen-holding type, firmly softly, flexible operation are accurate, convenient for control knife
Dynamic degree, movement and strength are used for short and small notch and delicate procedure mainly in finger, such as dissect blood vessel, nerve and cut abdomen
Film etc.；(3) holding, full hand hold knife handle, and thumb and index finger are tightly pinched at knife handle indentation, this method control knife is more stable, operation
Main activities force is shoulder joint, tissue hard thick, firmly biggish incision wide for cut coverage, as amputation, tendon cut,
Longer skin incision etc.；(4) counter to choose formula, it is a kind of transition form of pen-holding type, blade is flipped out, in order to avoid damage deep group
It knits, when operation is first pierced into, and moves point in finger, for cutting the hollow organs such as abscess, blood vessel, tracheae, choledochus or ureter, cuts
Tissue or expansion skin incision of disconnected clamp etc.；(5) finger pressing type firmly weighs, and index finger pushes down knife handle front end, and later half end is hidden in hand
In, this method control knife is slightly not flexible, is primarily adapted for use in the skin histology for being difficult to cut.
Existing scalpel generally includes knife handle and blade, and knife handle and blade are to be detachably connected, and before surgery, needs
It first to link together by autoclaving sterilizations such as blade and knife handles, then by blade and knife handle, after completion of performing the operation, by blade
Damage is removed, and knife handle disinfection stores, for use next time.
But existing scalpel has the following defects：
(1) existing scalpel is that tweezers is needed to assist mostly when dismantling or installing blade, pretty troublesome, and is easy to draw
Hurt healthcare givers, so that device is inconvenient to use；
(2) existing scalpel specific aim is very strong, that is, cuts different tissues and need using different scalpels, so that
It when being performed the operation, needs frequently to replace scalpel, is unfavorable for the progress of operation；
(3) existing scalpel has a single function mostly, can only carry out cutting operation, but in actual operation, it is sometimes desirable to
Other operations are carried out, such as shearing, hook are drawn, and are required using other Medical Devices, so that the instrument prepared needed for operation is numerous
It is more, and doctor is needed frequently to replace instrument, aggravate the burden of healthcare givers.
Summary of the invention
