Abstract

The utility model belongs to a medical appliance for operation on brain, comprising an upper tongs mouth (4) and a lower tongs mouth (5) which are hinged mutually. The upper tongs mouth (4) and the lower tongs mouth (5) compose a duckbill structure, and the back end of the upper tongs mouth (4) is fixed with one pressing plate (3). The back end of the lower tongs mouth (5) is fixedly provided with one handle (1). One spring (2) is fixedly arranged between the handle (1) and the pressing plate (3). The appliance can cause brain tissue to be separated by means of one-handed performance, and in addition, the utility model is favorable for the resection of intracerebral hematoma and tumour.

Description

Tractor for separating cerebral tissue

This utility model belongs to a kind of armarium, specifically a kind of used armarium of brain operation of doing.

Doing brain when operation, when the pathological changes in the cerebral tissue being excised or the hemorrhage of its inside etc. removed, traditional method is to utilize two monolithic brain spatula to operate, and promptly every hands takes a monolithic brain spatula to retract separation.Operation like this, because there do not have comparatively ideal armarium, doctor to do this operation to be all very difficult, a doctor is difficult to finish sometimes, so often needs two doctors' meticulous cooperation.

The purpose of this utility model is in order to overcome above-mentioned deficiency, to design a kind of cerebral tissue simple in structure, easy to use and separate retractor.

This utility model is to realize like this, it comprises that a pair of upper jaw that is hinged and its upper and lower jaw of lower jaw constitute the duckbill structure, be fixed with a pressing plate in the rear end of upper jaw, then be installed with a handle in the rear end of lower jaw, be installed with a spring between its handle and the pressing plate, so just constituted this cerebral tissue and separated retractor.Its operation principle is: behind the brain skin of fulgerizing, the handle of hand-held this retractor inserts in the cerebral tissue front end of duckbilled.Press...with one's finger pressing plate on the moving upper jaw inserts while separating, arrive the precalculated position after, with holder pressing plate is compressed the location, can operate by the duckbilled inner chamber of upper and lower jaw formation.It can be used for the excision of intracerebral hematoma and tumor.

Because what this utility model adopted is duckbilled mechanism, can do the separation of cerebral tissue with a hands, and be inserted into preposition.The another hands then can be done in the brain operation excision to pathological changes.Simple in structure, easy to use, be the ideal equipment that the medical personnel does cerebral surgery operation.

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Below in conjunction with accompanying drawing this utility model is described in detail: upper jaw of the present utility model [4], lower jaw [5] can be by the metal manufacturings, also can be with plastics or other materials manufacturing, and upper and lower jaw [4], [5] are hinged through hinge axis.As shown in the figure, upper and lower jaw [4], [5] constitute the duckbill structure.In order to control the unlatching of upper and lower jaw [4] [5], be fixed with a pressing plate [3] in the rear end of upper jaw [4]; Be installed with a handle [1] in the rear end of lower jaw [5].In order to guarantee that its upper and lower jaw [4], [5] use manual unlocking, auto-closing is installed with a spring [2] between pressing plate [3] and handle [1].Spring [2] remains closed upper and lower jaw [4], [5] formed duckbilled through to the effect between handle [1] and the pressing plate [3].In order to guarantee that its upper and lower jaw [4], [5] are held open state after opening, positioner of fixed installation between pressing plate [3] and handle [1].Like this, after open upper and lower jaw [4], [5], can guarantee the opening of its upper and lower jaw [4], [5] by this positioner, so that do various operations.

Claims

1, cerebral tissue separates retractor, and it comprises a pair of upper jaw that is hinged (4) and lower jaw (5), it is characterized in that: upper jaw (4) and lower jaw (5) constitute the duckbill structure, are fixed with a pressing plate (3) in the rear end of upper jaw (4); Be installed with handle (1) in the rear end of lower jaw (5), be installed with spring (2) between handle (1) and the pressing plate (3).
