Abstract
The utility model provides a callosum retractor which is composed of a traction bracket and a traction plate, wherein the traction bracket is in an X shape, the middle of the traction bracket is movably connected by a hinge, an annular handle and the traction plate are respectively arranged on both ends of the traction bracket, the traction bracket between the annular handle and the hinge is also provided with a cambered positioning gear rack and a locking handle which is corresponding to the cambered positioning gear rack, and the traction bracket between the hinge and the traction plate is also provided with a damping arm joint which can cause the traction plate to do rotation with 300 DEG. The callosum retractor has the characteristics of reasonable design, simple structure, high safety, convenient operation, etc.
Description
1, technical field
The present invention relates to a kind of operating theater instruments manufacturing technology, specifically a kind of corpus callosum retractor that is used for skull operation.
2, background technology
Corpus callosum is for connecting the dense plates in the corresponding district of both sides cerebral hemisphere, be that volume, top, temporal lobe are all corresponding with the callosity corpus callosum, the disease such as hemangioma, cyst that occurs in the callus tagma is much in clinical, present neurosurgery field, still it is many with brain spatula or the automatic dilator replacement of brain, as appearing the wild apparatus of art that the useless retractor that appears in the callus tagma, historical facts or anecdotes are executed this zone operation, but all undesirable, the quality and the progress of influence operation.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure easy to use, can improve the corpus callosum retractor of operation quality and progress.
The technical solution of the utility model realizes in the following manner, the corpus callosum retractor is to change a social system on the advantage basis of various operating theater instruments such as comprehensive mastoid process dilator and brain spatula to form, front end to retract plate similar to two brain spatula, anterior width is greater than the rear portion width when strutting to retract support, and the end design that retracts plate has the arc crimps of 15 degree.Favourable Rhizoma Atractylodis Macrocephalae open country appears the operation with the patient, and the length that retracts plate is 5cm, helps the excision of corpus callosum or dark cerebral tissue or ventricles of the brain diseased region, as big pathological tissues, can use two cover retractors simultaneously, helps appearing of diseased region.Retract shoulder joint is set on the support, help being positioned over the brain surface, also can prevent surgical instrument to brain tissue injury, the rear portion that retracts support is provided with the tooth bar detent mechanism, can arbitrarily adjust the retracting-exposing operative region, and can prevent the slippage of retractor.This corpus callosum retractor can not only be used for callus tagma operation, also can be used for brain and ICV operation, also can be used for abdominal operation, as Appendectomy etc.

Accompanying drawing 1 is the plan structure sketch map of corpus callosum retractor;
Accompanying drawing 2 is that the A-A of corpus callosum retractor is to structural representation;
Accompanying drawing 3 retracts the end face structure sketch map of plate for the corpus callosum retractor.
Labelling in the accompanying drawing is represented respectively; Retract support 1; Retract plate 2; Arc crimp 3; Shoulder joint 4; Arc-shaped rack 5; Locking handle 6; Annular hand grip 7; Hinge 8.
5, embodiment
Below in conjunction with accompanying drawing corpus callosum retractor of the present utility model is done following detailed description the in detail.
As shown in drawings, corpus callosum retractor of the present utility model is formed by retracting support 1 and retracting plate 2, retract support 1 and be the X shape, middle by hinge 8 flexible connections, annular hand grip 7 and retract plate 2 and be separately positioned on the two ends that retract support 1, retracting between annular hand grip 7 and hinge 8 also is provided with arc location tooth bar 5 and the locking handle 6 corresponding with arc-shaped rack on the support 1, hinge 8 with retract retracting between the plate 2 and also be provided with on the support 1 to allow and retract the damping shoulder joint 4 that plate 2 is done 300 degree rotations.
Retract plate 2 and be long 5cm, the rectangular thin plate of wide 2cm, a narrow limit that retracts plate 2 with retract support 1 and be connected, another narrow limit is processed with the arc crimp 3 of relative opposite direction bending.
Corpus callosum retractor of the present utility model is compared with existing technology, and has reasonable in design, simple in structure, peace The characteristics such as complete reliable, facilitating operation, thereby, have good value for applications.
