Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of Shin-bone internal broach internal fixation is led with fixation
Draw frame.
Background technique
Intramedullary needle internal fixation is chiefly used in long bone (such as stock, the upper arm, ruler, shin, radius) shaft fracture.Its advantage is that: marrow
Interior needle itself is more solid firm, and the postoperative early ambulant for being conducive to hurt limb with or without outer fixation that can lack is taken exercise;Skin is cut
Mouth is smaller, and periosteum stripping is limited in scope, and damages smaller;Intramedullary needle is long and has different shape corner angle, is embedded in pulp cavity, can achieve jail
The interior fixation leaned on, can be avoided the generation of rotation, sidesway and angulation displacement.The disadvantage is that: there need to be a locking equipment, operate more multiple
It is miscellaneous.The fracture that long bone is fixed with intramedullary needle, like passing through two section bamboo trunks with an axis.If the outer diameter of intramedullary needle is equal to length
The internal diameter of bone, such fixed function is all right, can stably keep contraposition, to line.
At present when carrying out intramedullary needle internal fixation, needs to arrange two doctors and patient's shank is fixed and is drawn,
Specifically, a doctor with the hands fixes patient thigh, and another doctor with the hands fixes patient's ankle, and two doctors are again
It is pulled in opposite direction, so that the shin bone to fracture resets, is then implanted into intramedullary needle to shin bone again.In implantation intramedullary needle
In the process, above-mentioned two doctor will also suitably adjust patient's shank position.Fracture of lower leg is drawn due to lacking at present
The traction device of reset, therefore current intramedullary needle internal fixation not only waste of manpower, but also by artificial for a long time to trouble
Person's shank pulls, and the hand muscle of doctor is easy fatigue, to generate shaking in distraction procedure, and then will increase in marrow
Needle is implanted to the difficulty in shin bone pulp cavity.
