Description
Technical field
What this utility model dilator related to is that a kind of surgical incision struts pincers, is specially adapted to the bone surgery otch and struts.
Background technology
When the bone surgery intramedullary pin is installed, need on patient's skin and flesh, open certain otch,, and, hole, can cause the skin and flesh damage, influence the otch recovery, cause patient's misery at cutting part unit protection device (drill bushing) so that on osteoderm, hole when inter-locking screw is installed.
Summary of the invention
On the purpose of this utility model at above-mentioned weak point, a kind of novel dilator is provided, can when intramedullary pin is installed, directly adopts the support set of dilator to strut directly boring of back the corrective surgery cutting part, can not cause the skin and flesh damage, and improve operation efficient, alleviated the corrective surgery misery.
Dilator takes following scheme to realize: the dilator structure is combined into one by rotating shaft by two calipers, the rear portion of caliper has handle, the handle rear portion is provided with anti-skidding elbow, and device has adjusting screw(rod) between two handles, and back-moving spring and adjusting nut are housed on the adjusting screw(rod), the caliper front portion is provided with jaw, support set is housed on the jaw, and support set is made of two semicircle stay tubes, installs respectively on two jaws, support set is provided with pilot hole, is used for the boring guiding.Can be provided with 1 to 2 support set on the jaw, it is consistent with the surgical hole position that support set is provided with the position.
Operation principle: after the corrective surgery mouth cuts, the support set of dilator is inserted corrective surgery skin and flesh otch until the sclerotin position, push handle jaw is strutted, drive support set and strut, adopt adjusting nut set lever position, making the jaw support set strut assurance necessarily dehisces, be that the hot spot that available drill bit medical laser direction finder produces in the sclerotin position is holed, be used to install inter-locking screw, after inter-locking screw assembles, take out dilator, unclamp locking nut, dilator automatically resets.
Dilator is reasonable in design, simple in structure, can easily surgical incision be strutted and carry out surgical operation, particularly install at the bone surgery intramedullary pin, when boring the inter-locking screw hole, can directly adopt the support set of dilator to strut at the corrective surgery otch, inter-locking screw is installed in directly boring, shortens operating time, improve operation efficient, can not cause the damage of patient's skin and flesh, alleviate the corrective surgery misery, can be widely used in surgery, bone surgery, can use separately, also can with the supporting use of other medical apparatus and instruments.
