Description

Arc-shaped puncture device and using method thereof

Technical Field

The invention belongs to the field of medical equipment, and particularly relates to an arc-shaped puncture device and a using method thereof.

Background

When the internal organs of the human body have substantive diseases, especially tumors, in order to clarify the pathology or directly perform ablation treatment on the focus, the puncture method is adopted, and the currently common method is to clarify the position and the depth of the focus and the skin needle insertion point after scanning the human body by tomography equipment such as magnetic resonance or CT and perform accurate puncture in the layer plane where the focus is located. However, the conventional positioning puncture is limited by the straight line modeling of the puncture needle, and only a straight line path can be selected for puncture, and if a certain straight line path exists on tissues which are not suitable for puncture, such as tumors which are easy to bleed, intertillage of the lung, bones such as scapular ribs and the like, the puncture path can be abandoned, and an angle which is far away or more difficult is selected for puncture, and what is more serious is that: some patients do not have any other suitable path for puncturing and can only abandon the treatment. At the moment, an arc puncture needle set which is simple to operate and similar to the traditional linear puncture needle in use method is needed, and the target part can be punctured by bypassing the tissues to be avoided in an arc needle inserting mode.

Disclosure of Invention

In view of the above prior art, the present invention provides an arc puncturing device and a method for using the same.

The technical scheme of the invention is realized as follows: the utility model provides an arc piercing depth, includes circular arc pjncture needle, convex circular arc pjncture needle guiding tube and guiding tube locating rack, and circular arc pjncture needle main part becomes circular arc and matches with convex circular arc pjncture needle guiding tube and makes the circular arc pjncture needle freely shuttle along the circular arc in the guiding tube, is equipped with the location strong point on the guiding tube and makes the guiding tube can fix to the locating rack on, the locating rack can be fixed to on human particular position and be equipped with a plurality of setpoints on the locating rack and can fix a position the guiding tube to.

The biopsy instrument has the beneficial effect that the biopsy instrument can bypass a special position to complete puncture and ensure a specific environment. Except for above puncture function, in practical application, because of the unable best position cooperation tradition puncture of selecting because of various reasons of part puncture patient, for example can't lie flat, can't lie prostrate or can't lie on one's side, at this moment, can use this arc piercing depth, to the requirement of patient's position during greatly reduced puncture.

Furthermore, a slide rail is arranged on the positioning frame, a slide block capable of moving and positioning along the slide rail is arranged on the slide rail, and a positioning supporting point is arranged on the slide block, so that the guide tube can be positioned to different positions along the slide rail, and thus, the guide tube can be positioned more accurately.

Furthermore, the arc-shaped puncture device is provided with an arc-shaped cutting knife, the head part of the cutting knife is a flat sheet-shaped knife head, the head part of the knife head is a knife body with a sharp angle gradually changing to a flat gradually-widening shape, and finally gradually changing to a cylindrical knife tail, the peripheral perimeter of the knife tail is slightly smaller than the peripheral perimeter of the knife body, so that the knife body and the knife tail can smoothly enter along with the knife tip after the knife tip cuts a puncture part, and the knife tail is connected with the arc-shaped knife handle. This design makes the wound easier to heal.

Furthermore, the arc puncture device is provided with an arc air bag guide head, the head of the air bag guide head is conical, the outer contour of the air bag guide head is the same as the size of the guide tube in an inflation state, and the head of the air bag guide head is connected with the inflatable bag through an air pipe so that the inflatable bag can inflate and deflate the head of the air bag guide head, so that the guide tube can be placed better.

Furthermore, the positioning support point on the arc-shaped guide pipe is overlapped with the arc center of the guide pipe and can be hinged with the positioning frame, the arc center of the arc-shaped cutter handle is provided with a hinged shaft which can be hinged with the positioning frame, the arc radius of the arc-shaped cutter handle is the same as that of the guide pipe, so that the guide pipe and the arc-shaped cutting knife can be interchangeable and can be hinged with the positioning frame at the same position, and the design and the positioning are more stable.

An arc puncture device using method, firstly, after scanning human body by tomography devices such as magnetic resonance or CT, the position and depth of focus and skin needle insertion point are determined; secondly, fixing the positioning frame at a specific position of a human body and confirming whether the positioning position can ensure that the puncture needle can reach the specified position or not through scanning calculation of tomography equipment such as magnetic resonance or CT (computed tomography); mounting the arc-shaped cutting knife on the positioning frame, rotating around the positioning frame, and using the knife tip to cut open the human body so that the focus of infection reaches the surface of the skin to form a flat channel; then taking out the cutting knife, placing the arc-shaped air bag guide head in the guide tube, inflating, fixing the guide tube on the positioning frame, placing the guide tube into the flat channel through the guide head, discharging the air in the air bag and taking out the guide head from the guide tube; and finally inserting the arc puncture needle for biopsy. The advantage of this design is that flat wounds heal more easily giving the patient a better protection against infirm conditions making it easier for the patient to recover.
