Description
technical field:
This utility model relates to medical apparatus and instruments, particularly a kind of clear crust cutter.
background technology:
The wound surface of traumatic patient is (as traffic accident causes the wound surface pulling, slideway causes the wound surface of rubbing), the wound surface of burn patient needs to change dressings often, and conventional instrument is wooden, bamboo or plastic thin slice at present, its effect is too single, can only be used at wound surface surface-coated medicine.And the crust layer that wound surface forms makes medicine cannot penetrate into smoothly wound surface nexine, thereby do not reach best Drug therapy effect.The result causing is exactly that wounds recovers slowly, and treatment cycle is long.Reach good therapeutic effect if want, can only be first by pocket knife, the multiple types of tools such as tweezers, scissors, cut the slough of wound surface, remove, and small pieces are infected to peeling off of crust, and then just can carry out the coating of medicine, complete the overall process of changing dressings.Use these instruments to carry out crust clearly, then the program time of changing dressings is long, use instrument is many, and complex operation has increased patient's misery.For solving this technical problem, there are some modified device, as Chinese patent application 95225649.5 discloses the special ploughing and weeding cutter of a kind of burn, its operate portions at cutter arranges flat sword and cutter tooth, is beneficial to cutting slough, is coated with flat medicine.For another example Chinese patent application 201020126539.9 discloses a kind of medicine changing knife for burn patients, comprises handle of a knife and blade, is further provided with cutter groove on handle of a knife, and one end of handle of a knife is provided with spin axis, between handle of a knife and described blade, is rotatably connected by spin axis.One end of blade is further provided with cutter tooth, and a side of blade is provided with blade, and opposite side is provided with buckling plate, between blade and described cutter groove, is fastened and connected by described buckling plate.Also be the cutting for crust, peel off, to change dressings.The improvement of above-mentioned technology is thrown away and is had defect in practical operation, be specially: 1, cutting, the crust sheet of peeling off is tiny trifling, usually falls into wound depths, while being sandwiched in meat in scale removal process, must use tweezers gripping, and for the crust sheet of fritter, take out and be difficult for, and tweezers end is sharp-pointed, usually stimulate wound to cause patient to mismatch, so further increased the weight of the situation of traumatic infection.2, for the thicker crust sheet of thickness, be combined closely with crust sheet because of tissue, cannot cut while peeling off, need to use hand file to polish, wear down or at coating, so that medicine reaches focus as far as possible, this operation must additionally assist hand rubbing and hairbrush to operate.Operation is comparatively complicated.In view of above-mentioned technological deficiency, need to occur that one is simple in structure, easy to use, clear crust is easy, and function is multiplex and avoid chip to invade the clear crust cutter of one of wound.
summary of the invention:
The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of simple in structure, easy to use, and clear crust is easy, and function is multiplex and avoid chip to invade the clear crust cutter of one of wound.
To achieve these goals, this utility model provides a kind of clear crust cutter, comprise handle of a knife, the integrated butt end that is provided with in one end of handle of a knife, the integrated taper end that is provided with of the other end, butt end is semicircle shape, one side of butt end is provided with some cutters tooth, and opposite side is provided with blade, wherein, described handle of a knife inner hollow, in described handle of a knife, be provided with trachea, the cross section of described handle of a knife is ellipticity, and two walls of described butt end are provided with multiple guiding gutters, guiding gutter is flat, and the sidewall of taper end is provided with union joint; Union joint, trachea and guiding gutter form gas passage, multiple guiding gutters are fan-shaped distribution, the outgassing direction of guiding gutter, towards blade or cutter tooth, is threaded between union joint and the taper end of handle, and blade, cutter tooth, guiding gutter, trachea and handle of a knife are one-body molded during fabrication.
The end thread of the taper end of described handle of a knife is connected with file body, file body is round table-like, and file one end of body and the taper end of handle of a knife form arcuation groove or V shape groove, and this arcuation groove or V shape groove are for being adjacent to the tiger's jaw position of user, filing board is rounded, between filing board and file body, is threaded.
The curve of described arcuation groove or V shape groove composite human body tiger's jaw.(tiger's jaw is between the back of the hand thumb, forefinger).
Described union joint is used for plugging together connection vacuum extractor or blower fan.Show, can, along guiding gutter of the present utility model blow gas to dispel chip, also can be sucked in vacuum extractor along guiding gutter of the present utility model.
This utility model all parts is stainless steel products, can disassemble high-temperature sterilization.
Union joint when use is positioned at tiger's jaw top.
The length of described handle of a knife is 10-12cm.
The width of described handle of a knife from butt end to taper end is gradually thin.
Advantage of the present utility model is: simple in structure, easy to use, clear crust is easy, and function is multiplex and avoid chip to invade wound, is specially:
1, can giving vent to anger of guiding gutter, can air inlet, and the equipment connecting according to union joint is selected different occupation modes, and, further, on trachea, switch can be set, switch is arranged on the wall of handle of a knife, by the closure or openness of on-off control trachea.
2, guiding gutter is fan-shaped distribution, and corresponding corresponding blade or cutter tooth, with peeling off crust sheet with cleaning crust sheet, make wound keep neat and tidy, reduce infection chance.
3, the taper end file body that is threaded, in the time of the thicker crust sheet of needs filing, is inverted handle of a knife.
4, various piece is disassembled, and is stainless steel products, and sterilization easily, can Reusability after sterilization.
