Abstract
The utility model relates to a brain mastoid tractor, and belongs to the technical field of medical instrument supply structures. The brain mastoid tractor is characterized by comprising two pieces of traction blades and a base connected with the tail end parts of the traction blades via pin shafts; the traction blades can rotate around the pin shafts, so that distance between the two pieces of traction blades is increased, and the purpose of tissue traction is achieved. The brain mastoid tractor is scientific and reasonable in structure, convenient to operate, strong in flexibility, good in traction and fixing effects, can well strut and expose an operation view, facilitates operations, and improves the safety of the operations.
Description
Technical field
This utility model relates to a kind of brain mastoid tractor, belongs to medical apparatus and instruments articles for use technical field of structures.
Background technology
In cerebral surgery operation, often use brain retractor, there is fixing shakiness or be difficult to fixing problem in the brain retractor in use at present, affects surgical effect, is unfavorable for the treatment of disease.
Summary of the invention
The purpose of this utility model is just to provide the brain mastoid tractor of a kind of scientific and reasonable for structure, handled easily, good fixing effect.
This utility model is achieved through the following technical solutions:
Brain mastoid tractor, its special feature is to comprise that two retract leaf 1 and base 2 with retracting leaf tail end and being connected by bearing pin 3, retracting leaf can rotate around bearing pin, thereby pulls open two distances that retract between leaf, reaches the object that retracts tissue.
Described retracting between leaf 1 and base 2 is provided with fixture 4, for the relative position between leaf that retracts after fixedly retracting.
Described leaf 1 head end that retracts is provided with 2-5 hook solid projection 5.
Described hook solid projection (5) is installed on and retracts on leaf, can dismantle easily, during use, can select as required to install quantity.
Described leaf 1 head end that retracts is also provided with the draw-in groove 6 that can regulate distance between hook solid projection, is convenient to regulate tractive effective area, exposes surgical field of view completely.
The beneficial effects of the utility model: scientific and reasonable for structure, easy to operate, motility is strong, tractive good fixing effect, can well strut exposure surgical field of view, and convenient operation, improves the safety of performing the operation.
Accompanying drawing explanation
Fig. 1: be this utility model structural representation;
In figure: 1, retract leaf, 2, base, 3, bearing pin, 4, fixture, 5, hook solid projection, 6, draw-in groove.
The specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model to be further described.
Brain mastoid tractor, comprises that two retract leaf 1 and base 2 with retracting leaf tail end and being connected by bearing pin 3, and retracting leaf can rotate around bearing pin, thereby pulls open two distances that retract between leaf, reaches the object that retracts tissue.
Retract between leaf 1 and base 2 and be provided with fixture 4, for the relative position between leaf that retracts after fixedly retracting.
Retract leaf 1 head end and be provided with 3 hook solid projections 5.
