Description

Puncture auxiliary guider under CT guide

Technical Field

The utility model relates to the technical field of medical equipment, specifically a CT guide is puncture supplementary bullnose down.

Background

The percutaneous puncture under the guidance of CT is a clinical operation technology with simple operation and small wound, which is widely applied to various clinical departments, an operator needs to accurately guide a puncture needle into a focus under the guidance of CT images of a patient, and the accuracy of puncture is always a difficult problem in clinical work. The prior art positioning methods are mostly limited to the positioning of puncture points, such as metal grids, positioning grids, etc.

The angle positioning during the puncture process is always lack of a proper auxiliary guiding device, and the puncture complications such as repeated puncture and bleeding are easily caused because the deviation of the angle from the preset angle is very large in the puncture process. Brings risks to the patient and presents challenges to the doctor. The existing medical puncture auxiliary guide can not solve the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a CT guide is puncture supplementary bullnose down to the puncture in-process that proposes in solving above-mentioned background art appears the angle and predetermined deviation is very much, causes puncture complications such as repeated puncture and hemorrhage easily, has brought the risk for the patient, has provided challenge scheduling problem to the doctor.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a supplementary bullnose of puncture under CT guide, includes the guide pole, the guide pole comprises guide pole A and guide pole B, guide pole B installs in guide pole A's inside, movable mounting has spherical hinge between guide pole A and the guide pole B, the chassis is installed to the guide pole bottom, the rubber subsides are installed to the chassis bottom, the bar recess has been seted up in the chassis outside.

Preferably, the guide rod A of the guide rod is fixed and immovable, the guide rod B is movable, the guide rod B can rotate in a single direction with the guide rod A through a spherical hinge, and the guide rod A and the guide rod B are made of opaque X-ray materials.

Preferably, the chassis is circular, the guide rod is vertically connected with the chassis, the rubber sheet is annular, and the diameter of the rubber sheet is larger than that of the chassis.

Preferably, the horizontal section of the guide rod a is circular, the horizontal section of the guide rod B is arc-shaped triangle, and one guide rod is attached between the guide rod a and the guide rod B.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up guide rod, chassis and rubber subsides, can effectively solve the problem that angle and predetermined deviation are many appearing in the puncture in-process, avoid repeated puncture and puncture complications such as hemorrhage, reduce patient's treatment risk to can provide help for young doctor's quick growth.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to fig. 3, the present invention provides an embodiment: the utility model provides a CT guide is supplementary bullnose of puncturing down, includes guide bar 7, guide bar 7 comprises guide bar A1 and guide bar B2, guide bar B2 installs the inside at guide bar A1, movable mounting has spherical hinge 3 between guide bar A1 and the guide bar B2, chassis 4 is installed to guide bar 7 bottom, rubber subsides 5 are installed to chassis 4 bottom, bar recess 6 has been seted up in the 4 outsides on chassis.

Further, the guide rod a1 of the guide rod 7 is fixed and immovable, the guide rod B2 is movable, the guide rod B2 can rotate in one direction with the guide rod a1 through the spherical hinge 3, and the guide rod a1 and the guide rod B2 are both made of an X-ray-opaque material.

Through adopting above-mentioned technical scheme, can pass through spherical hinge 3 through guide bar B2 and guide bar A1 between the unidirectional rotation, be favorable to adjusting the angle of guide bar B2.

Further, the chassis 4 is circular, the guide rod 7 is vertically connected with the chassis 4, the rubber sheet 5 is annular, and the diameter of the rubber sheet 5 is larger than that of the chassis 4.

Through adopting above-mentioned technical scheme, the diameter through rubber 5 is greater than the diameter of chassis 4, is convenient for fix chassis 4, avoids positioning error.

Furthermore, the horizontal section of the guide rod A1 is circular, the horizontal section of the guide rod B2 is arc-shaped triangle, and the guide rod A1 and the guide rod B2 are jointed to form a guide rod 7.

Through adopting above-mentioned technical scheme, through the laminating between guide bar A1 and the guide bar B2 two for a guide bar 7, convenient to use improves positioning accuracy.

The working principle is as follows: before using, check whether the function of each part is intact, accomplish earlier the puncture point location earlier during the use, local anesthesia, it is fixed to hug closely the puncture point with chassis 4 central point, rubber subsides 5 laminating chassis 4 and patient's skin, carry out CT scanning once more, clarify the space angle relation of focus and guide bar A1, open guide bar B2 angle of adjustment, after the adjustment finishes, guide bar B2 promptly is as puncture guide path, place the pjncture needle in bar groove 6 department, puncture the focus along guide bar B2 direction, after the puncture finishes, withdraw from this supplementary guide ware along bar groove 6 opening opposite direction, extract the pjncture needle again, the hemostasis by compression, after the operation finishes, it ends the device to place to sum up.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
