CN204814100U - Be used for positioner that punctures under CT guide - Google Patents

Abstract

The utility model provides a device that the puncture was fixed a position under was used for the CT guide for the CT scan can buckled and can fix the worm front end connection locating plate of angle patient localize puncture's device, installation biax digital display angle appearance on this locating plate, and the worm afterbody sets up the fixing clip, and the tail end sets up the shaping fixed swing handle of worm, and a plurality of puncture through -holes distribute on the locating plate. During the use, through the fixing clip with monolithic stationary on the support of CT bed board, under the CT scan condition, loosen earlier the worm and take shape fixed swing handle and adjust worm direction, shape, let the locating plate aim at the focus to confirm the angle through biax digital display angle appearance, the worm of screwing again takes shape and fixes the swing handle, selects the through -hole to puncture to the focus in a plurality of puncture through -holes, and is accurate reliable and stable.

Description

For CT Conducted Puncture positioner

Technical field

This utility model relates to a kind of device of locating with CT Conducted Puncture, specifically a kind of device for CT Conducted Puncture location.

Background technology

CT guided Percutaneous is human organ Deep Lesions pathologic sampling for diagnosing or the important method of some disease topical therapeutic.As Drug eluting stent, liver tumor percutaneous puncture micro-wave therapeutic etc.Current conventional method selects best aspect in CT scan, selects the angle θ of point of puncture, depth of needle d, puncture aspect needle track and Z axis, and record CT frame angle α.This technology puncture angle θ and α relies on spatial impression to be determined by operator usually at present, manually punctures.The method has following deficiency: 1, and artificial puncture requires that operator must have superb spatial impression and skilled " technology ".For small lesion or central focus, especially near cardiovascular injuries or other important organ, the accuracy of the method will show deficiency and risk is high.2, puncture angle uncertain, adds internal lesions displacement along with patient respiratory motion, needs repeatedly row CT scan to verify direction and the position of puncture needle in piercing process.During CT checking, the backshank of puncture needle drops because of gravity, and the position of puncture needle cannot be fixed, the repeatability of checking, poor reliability.Also people is had inclinometer to be fixed on CT bed board by coiled pipe or three-dimensional rack to guide puncture direction.But general coiled pipe motility is non-adjustable, employing be motility, the stability method all taking into account, compromise.Consequently dumb during adjustment puncture angle, unstable again during support puncture needle.

Summary of the invention

The purpose of this utility model is the accurate stable improving puncture, provides a kind of device for CT Conducted Puncture location, can adjust flexibly, the fast angle of stationary positioned plate and position under CT scan, punctures very easily.

This utility model comprises twin shaft digital display angle instrument, the technical scheme adopted is: can to the device of patient location puncture bent and can the coiled pipe front end connected positioning plate of fixed angle for CT scan, this location-plate is installed twin shaft digital display angle instrument, coiled pipe afterbody arranges fixing card, tail end arranges coiled pipe shaping fixed rotary handle, and location-plate distributes multiple puncture through hole.

The beneficial effects of the utility model are: arranged by above-mentioned such one, during use, to be fixed on by single unit system on the support that CT bed board fills by fixing card, namely under CT scan is guided, unclamp shaping fixed rotary handle, adjust location-plate flexibly, reach the puncture position of plan, angle.Then screw shaping fixed rotary handle, location-plate position is fixed.In this technical scheme, owing to arranging coiled pipe shaping fixed rotary handle at the tail end of coiled pipe, coiled pipe can be adjusted flexibly and fix, reach accurate positioning and the reliable and stable effect that punctures, easily there is deviation and error and cause the problem of repeated localised puncture in what solve that current CT scan relies on artificial puncture to exist completely, design science, easy to use, accurately and reliably.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is this utility model structural representation.

Detailed description of the invention

Shown in Fig. 1: can to the device of patient location puncture bent and can the coiled pipe 1 front end connected positioning plate 2 of fixed angle for CT scan, this location-plate 2 is installed twin shaft digital display angle instrument 3, coiled pipe 1 afterbody arranges fixing card 4, tail end arranges coiled pipe shaping fixed rotary handle 5, and location-plate 1 distributes multiple puncture through hole 6.

Coiled pipe 1 involved by this utility model is a kind of bent body by multiple steel bowl series combination, a location cable wire is provided with in body, and coiled pipe shaping fixed rotary handle 5 is set at tail end, unclamp coiled pipe shaping fixed rotary handle 5, body can bend arbitrarily, screw coiled pipe shaping fixed rotary handle 5, namely strain cable wire and the bending situation of body is fixed, can realize coiled pipe 1 thus needs with angle and bending adjustment angle can the needs of fixed angle.

Claims (1)

1. the device for CT Conducted Puncture location, comprise twin shaft digital display angle instrument (3), it is characterized in that: can to the device of patient location puncture bent and can coiled pipe (1) front end connected positioning plate (2) of fixed angle for CT scan, this location-plate (2) is upper installs twin shaft digital display angle instrument (3), coiled pipe (1) afterbody arranges fixing card (4), tail end arranges coiled pipe shaping fixed rotary handle (5), the multiple puncture through hole (6) of the upper distribution of location-plate (1).
