Description
This utility model belongs to a kind of cerebral surgery operation apparatus.
Cerebral operations, especially than the operation of position, deep, art is wild narrow and small and dark, has only the patient just can see the art open country clearly generally speaking.Need the assistant to cooperate during operation and retract cerebral tissue, expose the art open country.Because of the assistant cannot see the art open country, so cooperate often undesirable.Moreover cerebral tissue is more tender and lovely, and free-hand tractive firmly size is uneven, causes damage easily.Though " brain control oneself retractor " this import or counterfeit devices arranged at some large hospitals at present, involve great expense, volume is bigger, do not apply in most of hospitals.
The purpose of this utility model is according to the cerebral surgery operation needs, to provide a kind of volume brain little, convenient and practical, that be beneficial to popularization to retract holder.
Structure of the present utility model mainly is made up of two parts as shown in Figure 1, i.e. skull fixture and fixator for brain spatulas.This utility model is achieved in that skull fixture (1) and brain spatula fix (4) its cross section and be a U type structure, a hold-down screw (2) .(5 is respectively arranged in the above), be connected by one piece of attachment screw (3) between the two, the length of attachment screw (3) silk is the thickness of skull fixture and two connecting plates of fixator for brain spatulas.A quadrate brain spatula putting hole of prolate (6) is arranged on fixator for brain spatulas (4); Each parts material can select for use materials such as rustless steel to make.
Using method of the present utility model is: earlier skull fixture (1), be fixed on the skull by bone window edge, needs according to operation are adjusted brain spatula (7) degree of depth and flexibility, brain spatula (7) cranium outer end is fixed on the fixator for brain spatulas (4) by brain spatula putting hole (6), screws attachment screw at last.
The utility model has the advantages that: little, the portable band of volume, just occupy-place is little in detoxicating, the art, does not influence other operation; Processing technology is simple, and is cheap, is convenient to promote the use of; Be fixed together the brain tissue impairment of having avoided the activity of excuse portion to cause with head; Fixed, firmly evenly, help the operator operation, be particularly suitable for microneurosurgery and use.
Embodiment:
Brain retracts holder length overall 70mm, height overall 25mm, the adjustment angle between skull fixture and the fixator for brain spatulas is 90-180 °, lower plane one end of fixator for brain spatulas has a tablet, a hole is arranged on the tablet, and link to each other with skull fixture by attachment screw; Skull fixture is generally short slightly than fixator for brain spatulas, and skull fixture is got 25mm, and fixator for brain spatulas is got 45mm; The brain spatula putting hole is generally high 5mm, long 20mm, hold-down screw φ 5.
