Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an automatic puncture painless intervention treatment instrument for trigeminal neuralgia. Background Art

[0002] Trigeminal neuralgia is the most common cranial nerve disease, mainly manifested as recurrent paroxysmal severe pain in the distribution area of the trigeminal nerve on one side of the face. Females are slightly more than males, and the incidence rate can increase with age. Trigeminal neuralgia mostly occurs in middle-aged and elderly people, and the right side is more than the left side. The characteristics of this disease are: in the distribution area of the trigeminal nerve in the head and face, the onset is sudden, stops suddenly, like lightning, knife cutting, burning, intractable, and unbearable severe pain. Speaking, washing the face, brushing teeth, or even a gentle breeze on the face, or even walking can cause paroxysmal severe pain. The pain lasts for several seconds or minutes, and the pain occurs cyclically. The interictal period is the same as that of normal people.

[0003] At present, some patients have poor tolerance to drug treatment, and the drug effect becomes poor in some patients after 2 - 3 years, and surgical intervention treatment is required. The current "troika" of surgical treatment is: microvascular decompression, balloon compression, and radiofrequency ablation. Microvascular decompression requires craniotomy, and some patients are resistant. For elderly patients, the general anesthesia risk is high. Balloon compression and radiofrequency surgery have less trauma and need to puncture to the specified position of the foramen ovale. Currently, the puncture is performed under DSA or C-arm machine. Puncture under DSA has high accuracy, good implementation effect, and can adjust the puncture direction and position in real time, but there is a risk that the surgeon needs to be exposed to the radiation for a long time. While the operation under C-arm machine can reduce the exposure to radiation, but it does not have the real-time feature, and the position adjustment needs to be corrected by static radiography, the operation time is long, the number of punctures is large, and the resulting trauma and loss of adjacent structures also increase accordingly. Summary of the Invention

[0004] The main purpose of the present invention is to provide an automatic puncture painless intervention treatment instrument for trigeminal neuralgia, which solves the problem of the long time risk that the surgeon needs to be exposed to the radiation by setting digital subtraction angiography and the manipulator arranged outside the digital subtraction angiography, and solves the problem of manually replacing the puncture needle by setting the adjusting mechanism and the locking mechanism.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An automatic puncture painless intervention treatment instrument for trigeminal neuralgia, comprising digital subtraction angiography, a manipulator arranged outside the digital subtraction angiography, and a controller (not shown in the figure) for controlling the movement of the manipulator, and further comprising a mounting disk fixedly connected to the end face of the manipulator, a fixed disk fixedly connected to the end face of the mounting disk, an adjusting mechanism fixedly connected to the end face of the mounting disk, and a locking mechanism connected to the fixed disk;

[0007] The adjusting mechanism includes a driving motor fixedly connected to the end face of the mounting disc, a bearing disc fixedly connected to the output end of the driving motor, and a mounting seat movably arranged on the outer surface of the bearing disc for mounting the puncture needle;

[0008] The locking mechanism includes a sliding groove opened on the inner side wall of the fixed disc and an electric telescopic rod fixedly connected to the inner side wall of the sliding groove for driving the adjusting member.

[0009] Preferably, the adjusting member includes a movable block movably arranged on the top of the fixed disc, a mounting groove opened on the opposite side walls of the movable block, and a gear rotatably connected to the inner side wall of the mounting groove;

[0010] The mounting seat is fixedly connected to the outer side wall of the gear.

[0011] Preferably, the number of the adjusting members is several groups, and several adjusting members are distributed in a circular array with the central axis of the mounting disc as the origin.

[0012] Preferably, the locking mechanism further includes a slider fixedly connected to the output end of the electric telescopic rod, a rectangular groove opened on the top of the slider, and a roller rotatably connected to the inner side wall of the rectangular groove;

[0013] The outer side wall of the movable block is fixedly connected to the outer side wall of the slider.

[0014] Preferably, the locking mechanism further includes a toothed plate fixedly connected to the top of the fixed disc, and the number of the toothed plates is several and matches the number of the adjusting members.

[0015] Preferably, the locking mechanism further includes a storage groove opened at the bottom of the mounting groove, an electromagnet embedded in the bottom of the storage groove, a connecting spring fixedly connected to the bottom of the storage groove, and a locking rod fixedly connected to the end face of the connecting spring.

[0016] Preferably, the locking mechanism further includes two groups of clamping grooves opened on the outer side wall of the gear connecting shaft, and the central axes of the two groups of clamping grooves are perpendicular to each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, in the present invention, by starting the electric telescopic rod, the previous movable block is driven to disengage from the bearing disc, and then the driving motor is started to drive the bearing disc to rotate until the opening of the bearing disc faces the required movable block at this time. Then, the electric telescopic rod of this movable block is started to insert the movable block into the bearing disc, realizing the replacement of the puncture needle.

[0019] Second, in the present invention, by energizing the electromagnet, it is made to have magnetic force to adsorb and lock the rod to move downward until the locking rod completely retracts into the interior of the storage groove. At this time, the connecting spring is in a compressed state, and the locking rod disengages from the card slot. Then the moving block continues to move, causing the toothed plate to mesh with the gear, thereby achieving the rotation of the gear and rotating the mounting seat from a vertical state to a horizontal state. At this time, the gear will separate from the toothed plate, and another card slot is facing the storage groove. Then the electromagnet is powered off. At this time, the locking rod will be inserted into the interior of the card slot under the action of the connecting spring to fix the mounting seat again, preventing the mounting seat from moving randomly during the movement of the manipulator, and the replaced mounting seats are all in a horizontal state, thereby preventing the puncture needle on the mounting seat from interfering with the puncture process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figure 1-6As shown in the figure, a painless interventional treatment instrument for automatic puncture of trigeminal neuralgia includes a digital subtraction angiography 1, a manipulator 2 arranged outside the digital subtraction angiography 1, and a controller (not shown in the figure) for controlling the movement of the manipulator 2. It also includes a mounting disk 3 fixedly connected to the end face of the manipulator 2, a fixed disk 4 fixedly connected to the end face of the mounting disk 3, an adjusting mechanism fixedly connected to the end face of the mounting disk 3, and a locking mechanism connected to the fixed disk 4;

[0029] The adjusting mechanism includes a driving motor 501 fixedly connected to the end face of the mounting disk 3, a bearing disk 502 fixedly connected to the output end of the driving motor 501, and a mounting seat 505 movably arranged on the outer surface of the bearing disk 502 for mounting a puncture needle;

[0030] The locking mechanism includes a chute opened on the inner side wall of the fixed disk 4 and an electric telescopic rod 601 fixedly connected to the inner side wall of the chute for driving an adjusting member.

[0031] The adjusting member includes a movable block 503 movably arranged on the top of the fixed disk 4, mounting grooves opened on the opposite side walls of the movable block 503, and a gear 504 rotatably connected to the inner side wall of the mounting groove;

[0032] The mounting seat 505 is fixedly connected to the outer side wall of the gear 504, wherein the thickness of the gear 504 is equal to the distance between the opposite side walls of the movable block 503, ensuring that the gear 504 can only perform circular motion. A threaded groove is opened on the top of the mounting seat 505 for mounting puncture needles of different specifications through the threaded groove.

[0033] The number of adjusting members is several groups, and several adjusting members are distributed in a circular array with the central axis of the mounting disk 3 as the origin.

[0034] First, puncture needles of different specifications are installed on the mounting seat 505. Then the doctor comes out of the treatment room and controls the operation of the manipulator 2 through the controller set outside according to the images transmitted in real time by the digital subtraction angiography 1, thereby reducing the influence of radiation on the doctor;

[0035] When it is necessary to replace different puncture needles, the electric telescopic rod 601 is started to drive the previous movable block 503 to disengage from the bearing disk 502. Then the driving motor 501 is started to drive the bearing disk 502 to rotate until the opening of the bearing disk 502 is facing the required movable block 503 at this time. After that, the electric telescopic rod 601 of this movable block 503 is started to insert the movable block 503 into the bearing disk 502 to realize the replacement of the puncture needle.

[0036] Embodiment 2: As Figure 1-6As shown in the figure, a painless interventional therapy instrument for automatic puncture of trigeminal neuralgia includes a digital subtraction angiography 1, a manipulator 2 arranged outside the digital subtraction angiography 1, and a controller (not shown in the figure) for controlling the movement of the manipulator 2. It also includes a mounting disk 3 fixedly connected to the end face of the manipulator 2, a fixed disk 4 fixedly connected to the end face of the mounting disk 3, an adjusting mechanism fixedly connected to the end face of the mounting disk 3, and a locking mechanism connected to the fixed disk 4;

[0037] The manipulator 2 adopts a serpentine pneumatic arm. The control system sends motion commands to each joint of the serpentine pneumatic arm, and then drives the joint to move by adjusting the air pressure inside the joint until it moves along the planned path and finally reaches the target position, so as to realize the adjustable puncture direction and depth of the puncture needle.

[0038] The adjusting mechanism includes a driving motor 501 fixedly connected to the end face of the mounting disk 3, a bearing disk 502 fixedly connected to the output end of the driving motor 501, and a mounting seat 505 movably arranged on the outer surface of the bearing disk 502 for installing the puncture needle;

[0039] The locking mechanism includes a chute opened on the inner side wall of the fixed disk 4 and an electric telescopic rod 601 fixedly connected to the inner side wall of the chute for driving the adjusting part.

[0040] The locking mechanism further includes a slider 602 fixedly connected to the output end of the electric telescopic rod 601, a rectangular groove opened on the top of the slider 602, and a roller 603 rotatably connected to the inner side wall of the rectangular groove;

[0041] The outer side wall of the movable block 503 is fixedly connected to the outer side wall of the slider 602, where the slider 602 is located inside the chute, and the upper and lower outer side walls of the roller 603 are respectively abutted against the upper and lower inner side walls of the chute.

[0042] The locking mechanism further includes a toothed plate 604 fixedly connected to the top of the fixed disk 4. The number of toothed plates 604 is several and matches the number of adjusting parts.

[0043] The locking mechanism further includes a storage groove opened at the bottom of the installation groove, an electromagnet 605 embedded in the bottom of the storage groove, a connecting spring 606 fixedly connected to the bottom of the storage groove, and a locking rod 607 fixedly connected to the end face of the connecting spring 606. The locking rod 607 is made of ferromagnetic material. When the electromagnet 605 is energized and has magnetic force, it will adsorb the locking rod 607 to move down until the locking rod 607 is completely retracted into the interior of the storage groove. At this time, the connecting spring 606 is in a compressed state.

[0044] The locking mechanism further includes two groups of card slots opened on the outer side wall of the connecting shaft of the gear 504, and the central axes of the two groups of card slots are perpendicular to each other.

[0045] When the movable block 503 disengages from the carrier plate 502, the electromagnet 605 is energized, so that it has magnetic force to adsorb and lock the rod 607 to move downward until the locking rod 607 is completely retracted into the interior of the receiving groove. At this time, the connecting spring 606 is in a compressed state, and the locking rod 607 disengages from the card slot. After that, the movable block 503 continues to move, so that the toothed plate 604 meshes with the gear 504, so as to achieve the rotation of the gear 504, thereby rotating the mounting seat 505 from the vertical state to the horizontal state. At this time, the gear 504 will be separated from the toothed plate 604, and another card slot is facing the receiving groove. Then the electromagnet 605 is powered off. At this time, the locking rod 607 will be inserted into the interior of the card slot under the action of the connecting spring 606, and the mounting seat 505 is fixed again to prevent the mounting seat 505 from moving randomly during the movement of the manipulator 2, and the replaced mounting seats 505 are all in the horizontal state, so as to prevent the puncture needle on the mounting seat 505 from interfering with the puncture process.
