Abstract
The utility model discloses a neurocranium surgery cortex fistulization retracting device and belongs to the field of medical instruments. The neurocranium surgery cortex fistulization retracting device comprises a mind spatula, a loop and at least two fixed clamps, the mind spatula is arranged on the loop by a connecting chain, the fixed lamps are arranged on the loop by a connecting rod, and the connecting chain is arranged on an inner ring of the loop by a fixed device. The inner ring can be used as a track by the fixed device, and the fixed device slides and is fixed on the inner ring. The neurocranium surgery cortex fistulization retracting device has the advantages that the mind spatula can be fixed by the fixed device to achieve the aim that the mind spatula does not need operating manually in operation, a surgery is conducted, and the problem of post-operation complication of manual operation due to the fact that brain tissue is damaged in the surgery, surgery time is shortened and the like. The neurocranium surgery cortex fistulization retracting device has certain economic benefits and high practical value.
Description
Technical field
This utility model relates to a kind of brainpan operation cortex fistulation pull device, belongs to medical instruments field.
Background technology
At present when carrying out cranium brain keyhole surgery, when common separated cortex fistulization oral carries out deep operation, usually need to use brain spatula to carry out tractive, adopt this mode to have following drawback: the one, because the bone window is narrow and small, operating apparatus is too large or too many, can affect the space of partial operation; The 2nd because the bone window is narrow and small, can't take conventional self-retaining retractor fixing at bone window periphery, the part operation is not having the headstock to assist menisectomy fully, can't be on the headstock holder; The 3rd, when Deep Lesions was removed in cortex fistulation operation, cortex can obviously subside, and seals tiny fistulization oral, and carrying out energetically tractive this moment can affect on the contrary the deep and expose, and large-scale apparatus can't satisfy little auxiliary pulling power; The 4th, because Deep Lesions front and back and upper lower angle are large, the tractive of all angles that conventional apparatus can't facilitate.The 5th, it is required peripheral working place that large-scale apparatus can't provide Minimally Invasive Surgery.
The utility model content
In view of this, be necessary for above-mentioned problem, a kind of craniocerebral operations cortex fistulation pull device is provided, brain spatula is installed on the ring by connection chain, fixation clamp is installed on the ring by connecting rod, the easy fixing and miniature brain spatula that provides all angles to retract when having realized operation reaches the purpose of Minimally Invasive Surgery.
The technical solution adopted in the utility model: a kind of craniocerebral operations cortex fistulation pull device, comprise miniature brain spatula, ring and at least two fixation clamps, described brain spatula is installed on the ring by connection chain, fixture on the ring can be mobile fixing along ring 360 degree, and ring is fixedly linked by fixation clamp and the ring that is fixed on the bone window.
Further, described brain spatula is installed in by connection chain on the internal ring of ring, and described fixation clamp is installed on the outer shroud of ring by connecting rod.
Further, described connection chain is installed in by fixture on the internal ring of ring, fixture can internal ring as track, slide and fixing at internal ring.
Further, described brain spatula is connected with connection chain by rotator.
Further, the border circular areas diameter that surrounds between the described fixation clamp is less than the diameter of ring.
Further, described fixation clamp is worker's clevis.
Further, described connection chain is the distortion connection chain.
Further, described connecting rod is wire.
Further, brain spatula is easy miniature brain spatula.
This utility model is compared with prior art fixed miniature brain spatula by Simple fixing device in small space, do not need the purpose of performing the operation with the manually-operated brain spatula when not only having realized operation, and solved the problem that in the operation deep tissue is exposed and reduces brain tissue impairment, and greatly shortened the advantages such as operating time, had certain economic benefit and higher practical value.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of brainpan operation cortex fistulation pull device, comprise brain spatula 6 and ring 1 and three fixation clamps 5, described brain spatula 6 is installed on the ring 1 by connection chain 3, described fixation clamp 5 is installed on the ring 1 by connecting rod 7, described brain spatula 6 is installed on the internal ring of ring 1 by connection chain 3, described fixation clamp 5 is installed on the outer shroud of ring 1 by connecting rod 7, described connection chain 3 is installed on the internal ring of ring 1 by fixture 2, fixture 2 can internal ring as track, in internal ring slip and fixing, described brain spatula 6 is connected with connection chain 3 by rotator 4, the border circular areas diameter that surrounds between the described fixation clamp 5 is less than the diameter of ring 1, described fixation clamp 5 is worker's clevis, described connection chain 3 is the distortion connection chain, described connecting rod 7 is wire, and the device of the present embodiment highly is 100 millimeters, and the maximum gauge of ring 1 is 300 millimeters.
During use, three fixation clamps 5 are fixed on the skull operation opening part, make brain spatula 6 anglecs of rotation to correct position by rotator 4, connection chain 3 by distortion is adjusted height to correct position with brain spatula 6, by fixture brain spatula is slid into correct position and fixing, do not need to use the manually-operated brain spatula when realizing performing the operation with this, the purpose of performing the operation.
