Abstract

The invention discloses a kind of positioning devices of puncture angle guidance, more particularly to can multi-angle regulation accurate guiding puncture device, the puncture angle guiding locator include elongated bottom plate (Fig. 1), angle adjustment plate (Fig. 2), puncture guide pipe (Fig. 3).The puncture guide pipe 31 includes symmetrical clamp button of the spring 32,32 opposite face of clamp button of the spring is connected with the arc hollow slots 22 of angle adjustment plate respectively, horizontal bubble instrument 12 is contained in the middle lower end of the elongated bottom plate 11, and effect is the horizontal position for adjusting elongated bottom plate；Angled adjustable plate link slot 13 in the middle-end of elongated bottom plate and upper end, effect are to carry out right angle connection with the protrusion 26 of 21 bottom of angle adjustment plate.The present invention improves the accuracy that puncture needle reaches targeted site direction, shortens the time of puncture, easy to use.

Description

A kind of positioning device for the guidance of patient's puncture angle

Technical field

The present invention relates to determine under field of medical technology more particularly to CT positioning what patient's lesion puncture angle guided Position device.

Background technique

As people's lives level is continuously improved, the various advanced appearance for checking equipment, the discovery rate of disease is also got over Come more, and the treatment of disease needs accurate pathological diagnosis to support；CT guided percutaneous needle biopsy is accurately obtained with the smallest wound Pathological tissues are obtained, for pathological diagnosis use, provide foundation for clinic diagnosis, so CT guided percutaneous needle biopsy is most common, Use scope is also relatively wide.The step of CT guided percutaneous needle biopsy of current most of hospitals and method: being obtaining by CT scan Take faultage image, select inserting needle level, obtain depth of needle and needle angle using CT Survey Software tool, then doctor according to Personal experience carry out hand operation.It is this merely by experience and feel operation, be often difficult once success, need repeatedly repeatedly into The angle that inserting needle is adjusted after row CT scan not only extends the puncture time in this way but also considerably increases patient irradiation dose, Increase the occurrence probability of complication.We develop a kind of positioning device for the guidance of patient's puncture angle thus.

Summary of the invention

It is an object of the invention to: overcome the defect of the above-mentioned prior art, one kind is provided and is convenient for doctor when puncturing to disease The hand-held puncture angle guide device that people site of puncture is quick and precisely operated.

To achieve the goals above, present invention employs following technical solutions:

Puncture angle guide device includes elongated ruler bottom plate 11, horizontal bubble instrument 12, angle adjustment plate 21, punctures guiding Pipe 31.Lower end has horizontal bubble instrument 12, middle upper end to have the connection connected with angle adjustment plate 21 in the elongated ruler bottom plate 11 Slot 13 and puncture hollow slots 14, lower end are operation handle 15.There are three protrusions 26 and elongated ruler bottom for the lower end of angle adjustment plate Three 13 right angles of hollow slots on plate are connected；Angle index line 23 and two sections of arc hollow slots 22 are furnished on angle adjustment plate, The inner side edge of two sections of arc hollow slots is furnished with angular adjustment card slot 24.Puncture guide pipe 31 be elongated cylindrical tube by plastic production and At internal is that cavity both ends communicate, and puncture guide pipe upper and lower ends has clamp button of the spring 32 respectively, passes through clamp button of the spring and angle Regulating tank is mutually engaged.

Specific embodiment

Attached drawing discloses a kind of specific structure of embodiment of the present invention without limitation, with reference to the accompanying drawing to this This embodiment of invention is further described.

In the present embodiment, as seen from Figure 1, the elongated ruler bottom plate 11, wherein there is horizontal bubble instrument 12 in lower end, in There are the hollow slots 13 of connection angle demodulator in upper end and puncture hollow slots 14, and lower end is operation handle 15.

When it is implemented, from Figure 2 it can be seen that there are three the angle adjustment plate lower ends in protrusion 26 and elongated ruler bottom plate Three 13 right angles of hollow slots be connected, angle index line 23 and two sections of arc hollow slots 22 are furnished on the angle adjustment plate, The inner side edge of two sections of arc hollow slots 22 is furnished with angular adjustment card slot 24.

When it is implemented, by Fig. 2 and Fig. 5 as it can be seen that 31 upper and lower ends of puncture guide pipe have clamp button of the spring 32 respectively It is engaged by clamp button of the spring 32 with 24 phase of angular adjustment slot on angle adjustment plate.The puncture guide pipe is elongated cylinder Pipe, internal is that cavity both ends communicate.The puncture guide pipe is formed by metal or plastic production.

When it is implemented, first by CT scan select puncture lesion center level 41 and selected the patient's body surface point of puncture 46.The path that point of puncture is calculated using CT measuring tool and body surface are to the length of lesion and the angle of inserting needle, then doctor The positioning device (Fig. 5) of hand-held the invention patent puncture angle guidance, the central point (Fig. 2) 25 of the present apparatus is worn with the patient's body surface It pierces mark point (Fig. 4) 46 to be overlapped, stirs and puncture the angle (Fig. 4) 44 that guide pipe (Fig. 5) 31 to CT is measured, by puncture needle along wearing Thorn guide pipe hollow shaft 33 carries out after the patient's body surface puncture marks point 46 enters and reaches lump 42 in vivo along puncture path 45 The biopsy extraction of next step.
