Description
Technical Field
The utility model relates to a cerebrovascular puncture technical field specifically indicates a cerebrovascular disease operation is with puncture positioning mechanism.
Background
The interventional therapy in cerebral blood vessels utilizes the catheter operation technology to diagnose and treat the pathological changes in the blood vessels of the affected nervous system under the support of digital subtraction angiography (DSA system) controlled by a computer. The technology of intervention in cerebral blood vessel is a new developed method for preventing and curing cerebrovascular disease. The cerebrovascular interventional operation has better accuracy and small wound, so that the operation treatment effect is obviously improved.
But at present, when carrying out blood vessel of brain interventional therapy for patient, the blood vessel is directly pierced with the pjncture needle mostly, because the pjncture needle is mostly handheld by the doctor when piercing, can not guarantee to pierce the perpendicular of needle and pierce, the deviation appears easily, and current piercing depth is inconvenient to be fixed a position simultaneously, appears the phenomenon of puncture dislocation easily to the dismantlement and the change of the inconvenient pjncture needle of current piercing depth.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a location accuracy, convenient to use's puncture positioning mechanism for cerebrovascular disease operation.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the design provides a cerebrovascular disease operation is with puncture positioning mechanism, including pillow, holding ring and guide, two bases about fixed being equipped with on the pillow, the fixed rotation type attenuator that is equipped with in one side that the base faces each other, the holding ring is half-circular arc's platelike spare, and its both ends pivotally connect the rotation type attenuator, guide sliding connection the holding ring, be equipped with on the guide be used for the guide with holding ring relatively fixed's fastening bolt and the stand-through guide tube, the axis of stand-through the centre of a circle of holding ring.
Further, the rotary damper is a disc damper or a cylindrical linear damper.
Furthermore, the positioning ring is provided with a strip-shaped hollow part along the ring body.
Furthermore, the fastening bolt penetrates through the hollow part and the guide part at the same time, a nut is arranged on the fastening bolt, the positioning ring and the guide part are clamped through the nut, and the outer diameter of the nut is larger than the width of the hollow part.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model provides a cerebrovascular disease operation is with puncture positioning mechanism adjusts the angle of guide through rotatable holding ring, has the stand pipe that is used for the pjncture needle direction on the guide to guide itself can remove and fix on the holding ring, consequently can make the stand pipe aim at the operation region conveniently when using, thereby makes the doctor can stably, puncture conveniently.

Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Example 1, see FIGS. 1-2: the utility model relates to a puncture positioning mechanism structure for cerebrovascular disease operation, which comprises a pillow seat 1, a positioning ring 2 and a guiding piece 4, a left base 3 and a right base 3 are fixedly arranged on the pillow base 1, a rotary damper 5 is fixedly arranged on one side of the bases 3 facing each other, specifically, a shell of the damper is fixedly arranged on the bases 3, the positioning ring 2 is a semi-circular arc-shaped plate-shaped piece, the two ends of the positioning ring 2 are pivotally connected with the rotary damper 5, the two ends of the positioning ring are fixedly connected with the rotary shaft of the rotary damper 5, the guide part 4 is connected with the positioning ring 2 in a sliding way, a fastening bolt 6 for fixing the guide part 4 and the positioning ring 2 relatively and a through guide pipe 7 are arranged on the guide part 4, the guide pipe 7 is a tubular part, the outer side of the positioning ring is provided with an external thread which is connected with the guide part 4 through a thread, and the axis of the guide tube 7 penetrates through the circle center of the positioning ring 2.
The rotary damper 5 used in this embodiment is a disc damper, specifically a bidirectional damper, and the static moment, the starting moment and the moving moment of the damper are all greater than the gravity of the positioning ring 2 and the guiding member 4, so as to provide good support for the positioning ring 2 and the guiding member 4.
The positioning ring 2 is provided with a strip-shaped hollow 8 along the ring body; the fastening bolt 6 penetrates through the hollow 8 and the guide 4 at the same time, a nut 9 is arranged on the fastening bolt 6, the positioning ring 2 and the guide 4 are clamped through the nut 9, and the outer diameter of the nut 9 is larger than the width of the hollow 8.
In the specific using process, the head of a patient is placed on the pillow base 1, and the medical staff performs puncture positioning through the rotary positioning ring 2; the guide piece 4 is rotated to the tangent plane of the puncture part by rotating the positioning ring 2, the guide tube 7 is vertical to the puncture blood vessel by sliding the guide piece 4, and the correct angle is ensured; the fastening bolt 6 is then tightened and fitted with the nut 9 to secure the guide 4 to the positioning ring 2, after which a puncture needle may be used to penetrate the guide tube 7 and puncture the lesion.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
