Description

Technical Field

[0001] The utility model relates to the technical field of puncture devices, in particular to an arterial puncture trocar with ultrasound enhancement and X-ray dual development. Background Art

[0002] With the continuous advancement of medical imaging technology, ultrasound-assisted and X-ray imaging technologies are increasingly being used in vascular interventional procedures. However, existing arterial puncture cannulas have limitations in ultrasound enhancement and X-ray imaging. Furthermore, the transparent blood return chamber easily fills with blood, making it difficult to assess the position of the arterial puncture needle. This makes it difficult to simultaneously meet the requirements of high-precision positioning, clear imaging, and needle position assessment.

[0003] In actual operation, some patients may have difficulty locating the artery due to anatomical variations, obesity or other factors, making the puncture process challenging. At the same time, due to the operator's lack of technical level or experience, repeated punctures may occur, leading to complications such as hematoma, arterial spasm, vascular injury, and nerve damage. When conditions permit, the use of ultrasound to guide puncture can more accurately determine whether the needle has entered the artery, reduce the risk of mispuncture, and significantly improve the success rate of puncture. However, due to insufficient technology or experience, many anesthesiologists or surgeons still face puncture difficulties under ultrasound guidance, which requires us to improve the arterial puncture cannula to enhance its imaging effect and improve the success rate. At the same time, due to the existence of the above difficulties, the puncture time will be prolonged, causing the transparent blood return cavity to be quickly filled with arterial blood, making it difficult to assess the position of the arterial puncture needle. This requires us to improve the arterial puncture cannula to solve the problem of assessing the needle position.

[0004] Furthermore, due to forceful manipulation, mishandling, or accidental cutting, the arterial hose may break outside the patient's body, making it difficult to locate and only discovered when complications such as infection, bleeding, and organ damage occur. This requires improvements to the material of the arterial hose. The arterial hose described in this patent has X-ray imaging capabilities. When a rupture is suspected or confirmed, it can be located and grasped through X-ray fluoroscopy, sparing the patient the painful experience of surgical removal. For example, during an arterial puncture procedure at a hospital, the hose broke due to mishandling. Because the hose's location could not be confirmed, the patient ultimately had to undergo surgical removal.

[0005] Chinese patent document CN221154267U discloses a novel distal radial artery puncture sheath. This utility model discloses a novel distal radial artery puncture sheath, comprising an outer sheath, the outer sheath being a cylindrical structure, the surface of the outer sheath being coated with a hydrophilic smooth coating, an inner core being provided inside the outer sheath, the outer sheath being connected to a support, the tail end of the inner core passing through the support and being connected to a handle, the support being connected to a connecting tube, the connecting tube being connected to a pressure device, the left end of the support being concave, and the bottom of the pressure device being provided with a switch. The technical solution of this utility model can provide a special puncture sheath specifically for use by neurointerventionalists, which can be adapted to the needs of patients of different body shapes and minimize the risk of radial artery damage and spasm induction.

[0006] In the existing technology, the needle core cannot be positioned by ultrasound. Even if ultrasound is used for obese patients or patients with difficulty in ultrasound positioning, it consumes a lot of manpower and material resources and puncture is difficult. When the blood return cavity is full, the needle position cannot be determined in time and re-puncture is required. When a suspected or confirmed hose rupture occurs, the hose cannot be positioned by X-ray and surgical removal is required. Utility Model Content

[0007] In response to the shortcomings of the existing technology, the utility model provides an arterial puncture cannula needle with dual ultrasound enhancement and X-ray development. Under ultrasonic guidance, enhanced development positioning is performed according to the corrugated spiral groove segment on the needle core, which is conducive to more accurate judgment of whether the needle has entered the artery; the hollow chamber of the conical tower and the blood return part is separated by a pressure diaphragm. When the blood return part is filled with blood, the position of the needle can be evaluated by whether the water column in the conical tower changes; the hose is made of a polymer material that is not transparent to X-rays. If a suspected or confirmed break occurs, it can be located and grasped by X-ray fluoroscopy.

[0027] The tip of the needle core 11 protrudes from the front end of the flexible tube 10. The needle core 11 is a hollow steel structure with a corrugated surface in the first 2 centimeters to facilitate ultrasound imaging. The tip is designed with a blade surface, creating a sharper needle tip. The arterial flexible tube 10 is sheathed around the needle core 11. Made of a special material, the flexible tube 10 exhibits excellent X-ray imaging properties, does not affect ultrasound imaging, and exhibits high fracture resistance.

In addition, the arterial hose is made of polymer material and has X-ray imaging function. If a suspected or confirmed rupture occurs, it can be located and grasped through X-ray fluoroscopy, avoiding the patient from experiencing the pain of surgical removal. At the same time, the utility model also solves the problem of blood overflowing back in the arterial hose during arterial puncture, affecting the judgment of whether the needle core is accurately placed in the artery or whether it stays in the artery, thereby effectively overcoming the difficulties in existing arterial puncture technology and improving the safety and effectiveness of interventional treatment.
