Abstract
The utility model discloses a kind of external fixator for orthopedics dep half pin with blade, comprise the drill bit of tubular main rod body and main rod body front end, it is characterized in that, vertically be connected with a blade in the middle part of described main rod body, the vertical dimension of the blade tip distance main rod body axis of described blade front end is 4 ~ 14mm.External fixator for orthopedics dep half pin of band blade described in the utility model can bone tractive be utilize blade slowly to cut skin and kindred, the infection not easily caused because integumentary musculature is downright bad, the misery that effective minimizing sufferer is brought because of cutting skin, also has the advantages such as convenient taking-up in addition.
Description
Technical field
This utility model belongs to medical apparatus, is specifically related to a kind of external fixator for orthopedics dep half pin with blade.
Background technology
Half pin of injured bone is used for fixing in prior art, namely the steel nail be commonly called as, used several shortcoming: (1) when half pin fixing as in bone time, along with the tractive of bone extends, bone and skin all can have drawing-off to elongate every day, half pin also can drive by tractive thereupon, tears skin and flesh thereupon and can cause severe pain to patient; (2) half general pin entire body is all cylinder, when taking out, cylindrical stressed not strong, is not easy to take out.In order to solve the problem, this utility model comes therefrom.
Utility model content
The purpose of this utility model be to provide a kind of can improve vinyl cover on slideway before external fixator for orthopedics dep half pin of band blade of line speed and degree of stability.
For realizing above-mentioned utility model object, this utility model have employed following technical scheme:
A kind of external fixator for orthopedics dep half pin with blade, comprise the drill bit of tubular main rod body and main rod body front end, it is characterized in that, be vertically connected with a blade in the middle part of described main rod body, the vertical dimension of the blade tip distance main rod body axis of described blade front end is 4 ~ 14mm.
Adding the most direct object of blade at bone tractive is exactly, and the blade of blade can slowly cut skin and kindred, and the pain that the cylinder surface of half pin more whole than it goes tractive skin to bring will alleviate a lot, effectively decreases the misery of sufferer.
Preferably, described blade is Three-dimensional triangle type, and the side, two, left and right of described blade is the arc-shaped curved surface of indent, and the bottom surface of described blade is the arc-shaped curved surface of indent, is fixedly connected with described main rod body periphery.
Preferably, the sole length of described blade is 20 ~ 60mm.
Preferably, the upper end of described main rod body is also connected with extraction portion, and described extraction portion lateral symmetry is provided with the taking-up groove of indent.
The setting of taking out groove facilitates some taking-up instruments can firmly fix half pin fast, thus can take out half pin easily.
Preferably, the cross section of described extraction portion is regular hexagon.
The regular hexagon being set to corner angle of extraction portion cross section or other polygons, effectively can improve the impetus of whole half pin, convenient taking-up.
Utility model advantage:
External fixator for orthopedics dep half pin of band blade described in the utility model can bone tractive be utilize blade slowly to cut skin and kindred, the infection not easily caused because integumentary musculature is downright bad, the misery that effective minimizing sufferer is brought because of cutting skin, also has the advantages such as convenient taking-up in addition.

Fig. 3 is the structural representation of blade described in the utility model;
Wherein, 1, main rod body; 2, drill bit; 3, blade; 4, extraction portion, 5, take out groove, 31, the side, two, left and right of blade, 32, the bottom surface of blade.
Detailed description of the invention
Below in conjunction with accompanying drawing and a preferred embodiment, the technical solution of the utility model is further described.
Embodiment:
As shown in Figure 1: a kind of external fixator for orthopedics dep half pin with blade, comprise the drill bit 2 of tubular main rod body 1 and main rod body 1 front end, vertically be connected with a blade 3 in the middle part of described main rod body 1, the vertical dimension of blade tip distance main rod body 1 axis of described blade 3 front end is 10mm.
Adding the most direct object of blade 3 is exactly when bone tractive, and the blade of blade can slowly cut skin and kindred, and the pain that the cylinder surface of half pin more whole than it goes tractive skin to bring will alleviate a lot, effectively decreases the misery of sufferer.
As shown in Figures 2 and 3, in a preferred embodiment of the present utility model, described blade 3 is Three-dimensional triangle type, and the side, two, left and right of described blade 3 is the arc-shaped curved surface of indent, the bottom surface of described blade 3 is the arc-shaped curved surface of indent, is fixedly connected with described main rod body 1 periphery.
Preferably, the sole length of described blade 3 is 30mm.
As shown in Figure 1, in a preferred embodiment of the present utility model, the upper end of described main rod body 1 is also connected with extraction portion 4, and described extraction portion 4 lateral symmetry is provided with the taking-up groove 5 of indent.
The setting of taking out groove 5 facilitates some taking-up instruments can firmly fix half pin fast, thus can take out half pin easily.
Preferably, the cross section of described extraction portion 4 is regular hexagon.
The square being set to corner angle of extraction portion 4 cross section or regular hexagon or other polygons, effectively can improve the impetus of whole half pin, conveniently takes out.
It is to be noted; as described above is only the preferred embodiment explaining this utility model; not attempt does any restriction in form to this utility model according to this; be with; all any modification or changes having relevant this utility model of doing under identical utility model spirit, all must be included in the category of this utility model intention protection.
