Ladder hole is inside provided with, the ladder hole includes screwed hole, wedged hole, the screwed hole and institute are provided with the outside of screwed hole
State the mating connection of the second external screw thread, the wedged hole and the sleeve compression fit.
Preferably, an interstage sleeve is also socketed on the fixed handle, the interstage sleeve is provided with set for one end open, an other end
Bottom, internal thread is provided with the open side, and internal thread is connected with first external screw thread, the set bottom of the interstage sleeve with it is described
The rear end face correspondence gear of knife rod coordinates.
Preferably, the center at the set bottom of the interstage sleeve is provided with a screw, and be connected one and the knife in screw
The screw rod that the rear end face gear of rod coordinates.
Preferably, also it is socketed on the interstage sleeve, is also set in the ladder hole of the clamp sleeve in the clamp sleeve
There is resigning hole, the resigning hole is stepped down with interstage sleeve to be coordinated.
Preferably, the knife rod is in the arc-shaped.
Preferably, each described fluting is through the front and rear end of the pressing spring.
The main mechanism of the minimally invasive strong dermatotome treatment venous leg ulcers is that it can be effectively eliminated because of venous hypertension
There is the capillary network of pathological change on subcutaneous or manadesma with caused by stasis of blood stream and its hypoxemia of generation is white with activation
The toxic metabolites that cell is discharged.
Advantages of the present invention is：The strong dermatotome of wound provided by the present invention, is the morbidity according to venous leg skin ulcer
Mechanism is developed, and can guarantee that and varicose venous diseases of lower limbs is treated under conditions of minimally invasive, its simple structure, practical and convenient, is controlled
Therapeutic effect is good, can guarantee that postoperative body surface is attractive in appearance, and focus is removed completely.
