Description

Technical Field

[0001] The present invention belongs to the technical field of medical scanning instruments, and in particular relates to an ultrasound-guided cerebral vascular interventional puncture device. Background Art

[0002] Currently, interventional techniques for cerebrovascular disease are mostly performed on the femoral artery. Patients need to be bandaged for 24 hours after surgery. Radial artery puncture is more comfortable and allows patients to get out of bed and move around after surgery. The current radial artery puncture process is mostly performed with a common puncture needle, using a Seldinger needle (non-surgical percutaneous vascular insertion technique). There are the following disadvantages: (1) It takes multiple practices to become familiar with the puncture technique; beginners may fail to puncture, and even experienced puncturers may fail to puncture because each patient's vascular structure is different; (2) The vascular condition cannot be fully understood, which may cause accidental damage to the blood vessels and surrounding tissues. At the same time, compared with femoral artery puncture, radial artery puncture is more difficult and more likely to damage the surrounding blood vessels and nerves; (3) There is a lack of accurate positioning. In the past, ordinary ultrasound probes could not see the corresponding positioning point from the image, which affected the accurate operation of the puncturist; (4) It is impossible to fully understand the specific situation of the patient's interventional surgery site; (5) There is a lack of intraoperative monitoring and continuous assessment of the patient's condition. With the development of cerebrovascular interventional technology, radial artery puncture has become a hot topic in neurology treatment. The present invention can provide doctors with a simpler and more effective device to improve their skills and provide a guarantee for beginners to master the technology. It can also serve patients and avoid the existence of puncture complications.

[0003] In the prior art, application number 201610347648.5 discloses a real-time puncture navigation system and its navigation method, but the above-mentioned prior art only monitors the image position of the puncture needle during the puncture process, and is unable to prepare for and monitor related intraoperative conditions. Application number 202110070422.6 discloses an ultrasound probe puncture guidance device, which is essentially a fixed frame installed on an ordinary probe, and avoids blind spots by adjusting the angle. The disadvantages are that it cannot monitor for a long time, cannot observe the intraoperative situation, and lacks specific monitoring of vascular intervention. Application number 202110208334.8 is an ultrasound-guided puncture needle equipment, which increases the reflective interface of the puncture needle, which is conducive to ultrasonic wave reflection. It is essentially an improvement of the needle. Application number 202110233157.9 is an infrared vascular puncture needle that can detect blood vessels. It is a far-infrared device, lacks the preparedness of ultrasound guidance, and cannot dynamically observe changes in the condition. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultrasound-guided cerebral vascular interventional puncture device in order to solve the technical problem of needing to perform real-time infrared monitoring and locate the position of the puncture needle during the puncture process.

[0007] A bidirectional screw is inserted and rotated in the wireless ultrasonic probe, the bidirectional screw is centrally symmetrically arranged, and knobs are installed on both sides of the bidirectional screw that pass through the extension ends of the wireless ultrasonic probe.

[0008] The bidirectional screw is provided with a limit swivel, the limit swivel and the bidirectional screw are coaxially arranged, and the wireless ultrasonic probe is provided with an inner groove for rotating in conjunction with the limit swivel.

[0009] Wherein, a thread groove matching the external thread of the bidirectional screw is opened on the slider, and the two sliders are symmetrically arranged about the symmetry center of the bidirectional screw.

[0010] The pull rope is arranged in a "C"-shaped structure, the center of the pull rope is arranged above the ultrasonic transmitter, and a limit pin is inserted between the two locking pins.

[0011] The wireless ultrasonic probe is provided with a movable fastener that cooperates with the rotation of the puncture component, a needle mounting rod is inserted and slidably inserted into the puncture component, and the wireless ultrasonic probe is provided with a storage groove that cooperates with the flipping of the needle mounting rod.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1, refer to Figure 1-5 An ultrasound-guided cerebral vascular interventional puncture device includes a wireless ultrasound probe 1, an ultrasound transmitter 11 is installed on the wireless ultrasound probe 1, a puncture component 2 is installed on the side of the ultrasound transmitter 11, a pull rope 3 is provided on the ultrasound transmitter 11, a slider 43 is fixed at one end of the pull rope 3, and a locking pin 4 is fixed at the other end, a slide groove 42 is provided on the slider 43 for sliding with the locking pin 4, and a slideway 17 is provided in the wireless ultrasound probe 1 for sliding with the slider 43.

[0026] Among them, the wireless ultrasonic probe 1 is an ultrasonic detection and positioning device for puncture surgery, wherein the wireless ultrasonic probe 1 is wirelessly connected to the ultrasonic detection and positioning device, and the ultrasonic transmitter 11 is used to emit ultrasonic waves and detect the position of the pull rope 3 on the front side and the position of the needle during puncture. The two pull ropes 3 are set as double developing lines, and there are scales on the side shell 15 that are attached to the outside of the two developing lines, and the scale numerical units are marked. The spacing between the two developing lines can be adjusted by the position of the scale on the side shell 15 to change the distance between the two developing lines. The sliding arrangement of the slider 43 and the slide 17 is used to adjust the position of the two pull ropes 3. At the same time, the sliding arrangement between the locking pin 4 and the slide groove 42 is used to press the two pull ropes 3 tightly to prevent the pull ropes 3 from bending and loosening.

[0027] A bidirectional screw 16 is inserted and rotated in the wireless ultrasonic probe 1 . The bidirectional screw 16 is centrally symmetrically arranged. Knobs 14 are installed on both sides of the bidirectional screw 16 that pass through the extension ends of the wireless ultrasonic probe 1 .

[0028] The thread structures on both sides of the bidirectional screw 16 are symmetrically arranged, and the knob 14 can be used to drive the bidirectional screw 16 to rotate, so that the thread structures on both sides of the bidirectional screw 16 rotate spirally toward the center.

[0029] The bidirectional screw 16 is provided with a limit swivel 18 , which is coaxially arranged with the bidirectional screw 16 . The wireless ultrasonic probe 1 is provided with an inner groove for cooperating with the limit swivel 18 to rotate.

[0030] Among them, the coaxial setting between the limit ring 18 and the bidirectional screw 16 makes the rotation speed of the limit ring 18 and the bidirectional screw 16 equal when they rotate. At the same time, the rotation setting between the limit ring 18 and the inner groove makes the limit ring 18 keep a fixed position, so that the position of the bidirectional screw 16 remains unchanged when it rotates.

[0031] The slider 43 is provided with a thread groove 19 that matches the external thread of the bidirectional screw 16 , and the two sliders 43 are symmetrically arranged about the symmetrical center of the bidirectional screw 16 .

[0032] Among them, the thread groove 19 and the bidirectional screw 16 are screwed together and rotated, so that when the bidirectional screw 16 rotates, it can drive the slider 43 to slide in the slide 17. At the same time, the symmetrical arrangement of the threads on both sides of the bidirectional screw 16 enables the bidirectional screw 16 to drive the two sliders 43 to slide in opposite directions and with equal spacing.

[0033] The pull rope 3 is arranged in a “C”-shaped structure, the center of the pull rope 3 is arranged above the ultrasonic transmitter 11 , and a limit pin 41 is inserted between the two locking pins 4 .

[0034] The pull rope 3 is used to block the ultrasonic wave of the ultrasonic transmitter 11 to form a positioning effect, thereby positioning the working position of the puncture component 2.

[0035] The wireless ultrasonic probe 1 is provided with a movable fastener 13 that cooperates with the rotation of the puncture component 2, a needle mounting rod 25 is inserted and slidably inserted into the puncture component 2, and a storage slot 24 that cooperates with the flipping of the needle mounting rod 25 is provided on the wireless ultrasonic probe 1.

[0036] Among them, the movable firmware 13 is used to control the flipping use of the puncture component 2, so that after the puncture component 2 is flipped, the locking pin 4 is pushed to slide through the limit pin 41, thereby tightening the two pull ropes 3 to reduce the possibility of sliding and shifting of the pull ropes 3 during positioning use. The needle mounting rod 25 is used to fix the external puncture needle, and the storage groove 24 is used to store the needle mounting rod 25 to reduce wear.

[0037] Among them, the end of the needle mounting rod 25 away from the receiving groove 24 is rotatably connected to the screw 21, and the screw 21 is screwed together with the inner cavity of the puncture component 2. A pin 23 is fixed at the edge of the end of the needle mounting rod 25 away from the receiving groove 24. A slot 22 for sliding with the pin 23 is provided in the puncture component 2. A fixed swivel 26 is provided at the end of the screw 21 close to the needle mounting rod 25, and the fixed swivel 26 is rotatably connected to the concave part of the needle mounting rod 25.

[0038] Among them, when the screw 21 rotates, the threaded structure pushes the screw 21 and the puncture component 2 to produce axial sliding, thereby driving the needle mounting rod 25 to slide back and forth through the rotation connection between the fixed swivel 26 and the needle mounting rod 25. At the same time, under the sliding limit between the slot 22 and the pin 23, the needle mounting rod 25 is stably advanced forward and backward to reduce the dislocation and deviation between the needle and the wireless ultrasound probe 1 when the needle is advanced, thereby facilitating use during surgery.

[0039] A side shell 15 is provided on the side of the ultrasonic transmitter 11 , and a notch 12 for engaging with the pull rope 3 is provided on the side shell 15 .

[0040] The side shell 15 is provided with a scale, and the notch 12 is provided to limit the pull rope 3 on the one hand, and to facilitate identification of the scale on the other hand.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
