Description
Technical field
This utility model relates to medical surgical surgical medical technique with the apparatus field, particularly a kind of medical dermatome.
Background technology
At present in the clinical treatment of burn and shaping etc., carry out bark fetching, when transplanting skin and burn and cutting operation such as crust, need to use dermatome carry out the fly-cutting bark fetching.But aspect such as adjustment is short of this dermatome to some extent in the tangential, can not adapt to the whole body skin thin and thick everywhere needs different with the degree of tightness situation, and the doctor often by virtue of experience implements operation.Like this, not only bring to operation more highly difficult, to the operation success rate also bring certain influence.
Therefore, design a kind of simple in structurely, can assist a physician and take off that outward appearance is regular, thickness evenly the medical dermatome of skin-grafting be the technical problem that those skilled in the art need solution badly.
The utility model content
For overcoming the deficiency that above-mentioned similar technology exists, the purpose of this utility model provides a kind of assisting a physician and takes off the medical dermatome that outward appearance is regular, thickness is evenly made skin graft.
The technical scheme of this utility model is:
A kind of medical dermatome comprises cutter head, blade, knife bar and handle, and said blade is arranged on the cutter head, and said cutter head and knife bar removably connect, and the end of said knife bar is provided with handle.
As optimal technical scheme, the said cutter head of this utility model is connected fixing with knife bar through the mode that clamping perhaps is spirally connected.
As optimal technical scheme, the said handle surfaces of this utility model is enclosed with the nylon skid resistant course, is carved with anti-skid design above the said nylon skid resistant course.
As optimal technical scheme, the said cutter head of this utility model is vertical cutter head, and said blade is vertical cutting blade, and said blade vertically is arranged on the said cutter head, the vertical up and cutter head table plane of the blade of said blade.
As optimal technical scheme, the said cutter head of this utility model is the transverse cuts cutter head, and said blade is a transverse cutting blade, and said blade is horizontally installed on the said cutter head, the vertical up and cutter head table plane of the blade of said blade.
As optimal technical scheme, the said cutter head of this utility model is the ring cutting cutter head, and said blade is the ring cutting blade, and said cutter head and blade are one-body molded, and said cutter head is a hollow circular cylinder, and its top is a circular blade.
The beneficial effect of this utility model is: this utility model can be widely used in and go crust, bark fetching process and the preceding sampling process of bioassay (live body) before the skin grafting; Be that a kind of scope of application is extensive; Alleviate doctor's labor intensity; The medical apparatus and instruments that is easy to learn and use, regular through its skin-grafting outward appearance of taking off, thickness is even.

Fig. 3 is the structural representation of this utility model embodiment 3.
The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.
With reference to accompanying drawing 1; The specific embodiment 1 of this utility model is proposed; A kind of medical dermatome comprises cutter head 1, blade 2, knife bar 3 and handle 4, and said blade 2 is arranged on the cutter head 1; Said cutter head 1 removably connects with knife bar 3, and said cutter head 1 is connected fixing with knife bar 3 through the mode that clamping perhaps is spirally connected.Cutter head and knife bar are for removably connecting; Like this; The doctor can select suitable cutter head according to the practical situation of different parts, can guarantee to deacclimatize different skin thickness with the high cutter head of different swords; And can guarantee the depth of cut of expecting, thereby can when guaranteeing surgical effect, avoid producing cicatrix and pigmentation.
The end of said knife bar 3 is provided with handle 4.Said handle 4 is coated with the nylon skid resistant course, is carved with anti-skid design above the said nylon skid resistant course.The setting of handle and nylon skid resistant course, it is stable to make that the doctor holds when operation, can not skid, and makes operation more laborsaving, easy.
Said cutter head 1 is the transverse cuts cutter head, and said blade 2 is a transverse cutting blade, and said blade 2 is horizontally installed on the said cutter head 1, and the blade of said blade 2 is up and perpendicular to cutter head table plane.
With reference to accompanying drawing 2; The specific embodiment 2 of this utility model is proposed; The difference of itself and embodiment is: said cutter head 1 is vertical cutter head; Said blade 2 is vertical cutting blade, and said blade 2 vertically is arranged on the said cutter head 1, and the blade of said blade 2 is up and perpendicular to cutter head table plane.
With reference to accompanying drawing 3, the specific embodiment 3 of this utility model is proposed, said cutter head 1 is the ring cutting cutter head, and said blade 2 is the ring cutting blade, and said cutter head 1 is one-body molded with blade 2, and said cutter head 1 is a hollow circular cylinder, its top is a circular blade.During the present embodiment operation, hold handle, the ring cutting cutter head perpendicular to skin, along the axis rotary handle, can be caused circular damaged wound surface with downcutting with ring cutting blade diameter skin of a size, this wound surface is a regular circular.Said cutter head removably is connected with knife bar, can change the ring cutting cutter head of different bores as required, causes the wound surface of different sizes, makes the wound surface adjustable size.
The above is merely the preferred embodiment of this utility model; Be not therefore and the claim of restriction this utility model; Every equivalent structure transformation that utilizes this utility model description and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of this utility model.
