A kind of mammary gland Mai Motong Minimally Invasive Surgery cutter
Technical field
This utility model relates to operating theater instruments, relates in particular to a kind of scalpel that is applicable to be used in the mammary gland Mai Motong microtrauma puncture biopsy incision skin.
Background technology
The full name of Mai Motong is rotary-cut system of vacuum-assisted mammary gland Wicresoft (The Mammotome System), is a kind of advanced person's Minimal Invasive Biopsy system, is mainly used in Wicresoft and obtains the mammary gland tissue sample, excision benign tumor etc.At present, be to adopt common knife blade to cut skin in the Mai Motong Minimally Invasive Surgery.The width of general surgery blade and Mai Motong operation are usually inconsistent, roomy blade easily strengthens wound surface when cutting skin, and common knife blade is plane more, a little less than the penetrance, be difficult for cutting holostrome skin, be difficult to grasp well dynamics, easily about vibrations, this just causes the larger cutting damage of surrounding tissue.Too narrow knife blade may cause otch too small when cutting skin on the other hand, and this just needs the Mai Motong puncture needle that skin is cut, and causes the otch profile irregular, is cauliflower-like, also causes the damage of otch surrounding tissue.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, this utility model provides a kind of convenient puncture, cuts holostrome skin, can reduce a kind of mammary gland Mai Motong Minimally Invasive Surgery cutter of wound surface.
Technical scheme: for achieving the above object, a kind of mammary gland Mai Motong Minimally Invasive Surgery cutter of the present utility model, comprise handle of a knife, be installed in the tool rest of handle of a knife front end and be located at blade on the tool rest, described blade front end forms tip, described blade both sides are provided with blade, and described blade width is corresponding with the width of Mai Motong micro-wound puncture needle.
Handle of a knife described in the utility model or tool rest are cylindrical or elliptical cylinder-shape or Polygonal column shape.
Described tool rest is provided with the skull for the protection of blade.Preferably, the shape of skull is corresponding with the shape of described handle of a knife, forms one with described handle of a knife after skull covers on handle of a knife.Described tool rest side is provided with convex, and is corresponding with the groove of being located at the skull inboard, is beneficial to skull is buckled on tool rest, prevents that skull from coming off.
The every side of described blade is 1.8 ~ 2.2mm from tip to the blade overall length.Preferably, the every side of described blade is 2.0mm from tip to the blade overall length, and this length can realize that the holostrome of skin cuts.Blade width is corresponding with the width of Mai Motong micro-wound puncture needle, can realize that surgical wound surface minimizes.
Grasp for convenient, described handle of a knife is provided with the reticulate pattern that is beneficial to grasping.
Beneficial effect: a kind of mammary gland Mai Motong Minimally Invasive Surgery cutter of the present utility model is rationally novel in design, simple in structure, can be perfectly and the Mai Motong microwound operation needle be used, this scalpel can conveniently vertically be cut when cutting skin, avoid vibrations to make wound surface minimum, the holostrome that can realize simultaneously skin cuts, and makes things convenient for operator to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in Figure 1, a kind of mammary gland Mai Motong Minimally Invasive Surgery cutter of the present utility model comprises handle of a knife 1, is installed in the tool rest 2 of handle of a knife 1 front end and is located at blade 3 on the tool rest 2 that tool rest 2 is provided with the skull 6 for the protection of blade 3.Handle of a knife 1 or tool rest 2 are cylindrical or elliptical cylinder-shape or Polygonal column shape, and tool rest 2 sides are provided with convex 7, and are corresponding with the groove of being located at the skull inboard, can realize skull is buckled on tool rest, prevent that skull from coming off.Wherein handle of a knife 1, tool rest 2, skull 6 are made for plastic material, and blade is that metal material is made.
Blade 3 front ends form tip 4, and blade 3 both sides are provided with blade 5, and 5 overall lengths are 1.8 ~ 2.2mm to blade 3 every sides from tip 4 to blade, are preferably 2.0mm, and skin holostrome thickness average out to 1.0mm can realize the holostrome incision of skin and the incision of part fat deposit.Blade 3 width are corresponding with the width of Mai Motong micro-wound puncture needle, match with the Mai Motong micro-wound puncture needle.Be provided with the reticulate pattern 8 that is beneficial to grasping at handle of a knife 1.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
