Abstract

The utility model provides a locator for brain surgery, which can accurately draw an incision line according to the position of an intracranial space-occupying lesion on a CT (Computed Tomography) film and the distance between the lesion edge and the front part of the skull and between the lesion edge and the rear part of the skull. The locator comprises a locating ruler supported through a bracket, wherein the locating ruler is semicircular; a locating pen is arranged on the locating ruler; the rear end of the locating pen is sleeved onto the locating ruler and can slide along the locating ruler; supporting shafts are arranged at the two ends of the locating ruler; and the supporting shafts are in sleeve joint with the bracket. According to the locator for brain surgery, the locating ruler is set to be semicircular so as to adapt the brain shape, so that the operating position can be located more accurately. An operating pen is in threaded connection with the bracket, so that the operating pen can be conveniently adjusted in length. The locator for brain surgery has the advantages of a simple structure and convenience for use.

Description

Cerebral surgery operation is used localizer

Technical field

This utility model relates to a kind of cerebral surgery operation and uses localizer.

Background technology

During the intracranial spaceoccupying lesion operation; Generally be promptly to draw lobe according to the position of pathological changes on CAG, ventriculography or the CT sheet cut line of on patient's scalp, drawing; This picture lobe method is often not accurate enough; Sometimes open the bone lobe and go into just to find behind the cranium that the pathological changes center not under otch or bad because of surgical field of view, and causes pathological changes not excise fully, directly influence surgical effect.

The localizer that uses at present is a positioning rule, and an angle square and vernier are arranged, and a slide rule is arranged on the vernier, and the slide rule lower end also has the positioning rule that can slide relatively with it of a level, and the positioning rule face is provided with positioning through hole, and structure is complicated, the manufacturing process trouble.

Summary of the invention

The purpose of this utility model provides a kind ofly uses localizer according to the position on the intracranial space-occupying lesion CT sheet and pathological changes edge far from scalp, accurately the draw cerebral surgery operation of cut line of the distance before and after the skull.

Said purpose realizes through following scheme:

A kind of cerebral surgery operation is used localizer, comprises the positioning rule through stent support, and said positioning rule is semicircle, is provided with pen with means for holding it in right position above the said positioning rule, and said pen with means for holding it in right position rear end is socketed on the positioning rule and can slides along positioning rule.

Said pen with means for holding it in right position rear end is fixed on the connector, and said connector is socketed on the positioning rule.

Between said pen with means for holding it in right position and connector through being threaded.

Said positioning rule two ends are provided with back shaft, socket between said back shaft and support.

This utility model is set to semicircle with positioning rule, to adapt to the brain profile, can position surgery location more accurately.Between operation pen and support through being threaded the length of convenient adjustment operation pen.The utlity model has simple in structure, the convenient advantage of using.

Description of drawings

Fig. 1 is the structural representation of this utility model.

The specific embodiment

Set forth this utility model in detail preferred embodiment below in conjunction with accompanying drawing.

A kind of cerebral surgery operation is used localizer, comprises the positioning rule 1 that supports through support 4, and said positioning rule 1 is semicircle, is provided with pen with means for holding it in right position 2 above the said positioning rule 1, and said pen with means for holding it in right position 2 rear ends are socketed on the positioning rule 1 and can slide along positioning rule 1.

Another kind of scheme does, the rear end of said pen with means for holding it in right position 2 is fixed on the connector 3, and said connector 3 is socketed on the positioning rule 1 and can prolongs positioning rule 1 and slide.Between said pen with means for holding it in right position 2 and the connector 3 through being threaded.

The two ends of said positioning rule 1 are provided with back shaft 5, socket between said back shaft 5 and the support 4.

This embodiment is the protection domain that the exemplary illustration of this patent is not limited it; Those skilled in the art can also carry out the part to it and change; The short of spirit that exceeds this patent all is regarded as the replacement that is equal to this patent, all within the protection domain of this patent.
