Abstract

The utility model provides a chronic subdural hemorrhage drainage tube guide needle, which comprises an integral metal circular bar, wherein an elbow is bent at the front end of the metal circular bar; and the back end of the metal circular bar is provided with a lifting lug. During chronic subdural hemorrhage trepanation and drainage, the tail end of the guide needle is inserted from a side hole of a silica gel drainage tube, the head part of the drainage tube is bent through skull trepanation, the guide needle is gently introduced into a subdural hemorrhage cavity and is withdrawn, and the drainage tube and putamen are inserted into the subdural hemorrhage cavity in parallel, so that the drainage tube inserted into the putamen is prevented damaging a cerebral cortex, operative complications are reduced, and the operation effect is enhanced; and meanwhile, the chronic subdural hemorrhage drainage tube guide needle has the advantage of easiness for operating.

Description

CSDH drainage tube guid needle

Technical field

This utility model relates to the guid needle of being convenient to insert drainage tube intracranial CSDH chamber.

Background technology

In the CSDH trepanation and drainage; The silica gel drainage tube directly imports the CSDH intracavity, because CSDH trepanation and drainage art sphenotresia is less, drainage tube is difficult for inserting in the subdural hematoma chamber; Troublesome poeration, and the danger of latent lesion cerebral tissue is arranged.

Summary of the invention

In order to make the silica gel drainage tube make things convenient for to such an extent that insert in the CSDH chamber, this utility model proposes CSDH drainage tube guid needle.

For this reason, the technical scheme of this utility model is: CSDH drainage tube guid needle, comprise a bulk metal circle bar, and it is characterized in that: the front end of round metal bar is bent with elbow, and the rear end of round metal bar is provided with hanger.

Beneficial effect: in the CSDH trepanation and drainage, the guide pin end is penetrated through silica gel drainage tube side opening, through sphenotresia; Make the drainage tube head-bent, softly import the subdural hematoma intracavity, then the withdraw of the needle; Insert in the subdural hematoma chamber drainage tube is parallel with dura mater again; Prevent to insert under the dura mater drainage tube cerebral cortex that stabs, reduce postoperative complication, improve surgical effect; Simultaneously, has advantage simple to operate.

Description of drawings

Fig. 1 is the front view of this utility model.

Fig. 2 is the vertical view of this utility model.

The specific embodiment

Like Fig. 1, shown in 2, it is following to further describe this utility model: CSDH drainage tube guid needle, comprise a bulk metal circle bar 1, and the front end of round metal bar is bent with elbow 2, and the rear end of round metal bar is provided with hanger 3.

The concrete making: take the round metal bar of the about 25cm of length, diameter is 0.2-0.3cm, and the smooth circle of front end is blunt; Crooked 30 degree apart from the front end 4cm place of round metal bar; Apart from crooked once more 60 degree in the front end 1cm place of round metal bar, twice flexural deformation is in same direction, thus the formation elbow; The end of forming metal circle bar forms hanger.

The structure of this utility model is not limited to above-mentioned embodiment, as long as be provided with elbow at the front end of round metal bar, can insert the silica gel drain smoothly in the CSDH chamber, all should drop in the protection domain of this utility model.

Claims

1. CSDH drainage tube guid needle comprises a bulk metal circle bar, and it is characterized in that: the front end of round metal bar is bent with elbow, and the rear end of round metal bar is provided with hanger.

2. CSDH drainage tube guid needle according to claim 1 is characterized in that: the diameter of round metal bar is 0.2-0.3cm; Crooked 30 degree apart from the front end 4cm place of round metal bar, apart from crooked once more 60 degree in the front end 1cm place of round metal bar, twice flexural deformation is in same direction, thus the formation elbow.
