Abstract

The utility model relates to a laser auxiliary X-ray positioning device, which realizes the double positioning of the X-ray and laser to an X-ray positive foreign body and has high positioning precision. After the X-ray positive foreign body is positioned by the X-ray, the laser beam can indicate the position, the surgical doctor has an unequivocal object, the surgical procedure is quickened, the suffering of patients is decreased, and the X-ray exposure of the patients and the surgical doctor is decreased. The utility model can also be used for the external fixation of fracture, etc.

Description

Laser is assisted the X-ray positioner

Laser is assisted the X-ray positioner, is mainly used in positive foreign body operation of X line and external fixation of fracture etc., and its positioning accuracy height is simple and easy to do, shows and understands, has improved the operation quality, has alleviated patient's misery, has reduced the roentgen radiation x amount of patient and operative doctor.

Taking foreign body operation key is that want accurately the location, the positive foreign body operation of the X line C of use type arm X line machine is got more by present hospital with good conditionsi, no matter be before the art, make film in the art, still have an X-rayed in the art, all be difficult to realize the hi-Fix in the art, intuitive is poor, and the operative doctor target is indeterminate, thereby has increased the difficulty of operation.

The purpose of this utility model provides the auxiliary X-ray positioner of a kind of laser, is used to improve the positioning accuracy of the positive foreign body of X line, also can be used for external fixation of fracture etc.

This utility model laser is assisted the X-ray positioner, is on basis, former traditional X-ray location, has increased the laser auxiliary locator, and the positive foreign body of X line location is clearly indicated.With reference to Fig. 1, laser designator (1) adopts the magic lantern indicator, is mounted on light chopper or the X-ray machine head shell.Reflex reflector lens (2) be installed in the light chopper or X linear window guard shield in, in order to the laser beam of reflector laser indicator (1).Foresight is pulled (3) and is made up of Transmission X linear liner plate and location foresight that can be good, and the circular hole of about 2mm is opened at the liner plate center.The location foresight can adopt two kinds of versions, is the center with the liner plate circular hole all, a kind of employing annular high desnity metal, and the about 2mm of internal diameter is about the about 1mm of interior external diameter difference; A kind of high desnity metal silk section that adopts is evenly arranged into by outside radial of circular hole.Location or timing sight plate circular hole are fixed in light chopper or window expands cover X line central beam position.High desnity metal scoring ring (4) is the annulus of internal diameter 5-20mm, and location and timing are fixed in image amplifier (6) or the center is removed in the image enhancing, reaches X line focus (5), foresight center and scoring ring center sight alignment.For making laser beam be gone into to inject, reflect and will be offered two circular holes about 2mm to light path by light chopper or window guard shield, reflection hole is positioned at X floss central beam position, and location or timing foresight are pulled circular hole and overlapped with reflection hole.Adjusting laser designator (1) and reflecting optics (2) makes laser beam shine the scoring ring center by the sight plate circular hole.

The auxiliary X-ray positioner of laser has solved the positioning accuracy problem of the positive foreign body operation of X line, after whole device correction is good, during the X-ray location, as long as the foreign body image enters the scoring ring center, patient posture and X line seat in the plane are put and are remained unchanged, and close the X line, open laser designator, laser light reflected Shu Biran clearly indicates orientation, foreign body place, and increases the tracking foreign body with the degree of depth of the edge of a knife.

Description of drawings
