Long-handled probe interventional ultrasonic puncture depth control device

Abstract

The invention provides a long-handle probe interventional ultrasonic puncture depth control device, which relates to the field of interventional ultrasonic equipment in medical equipment, which includes a puncture needle guide device and a depth control device; the puncture needle guide device is provided with a device for guiding the puncture needle The puncture guide cylinder is provided with a probe fixing wing for connecting a long-handled ultrasonic probe under the puncture guide cylinder; the depth control device is provided with a clamping device for fixing the position of the puncture needle, and is also provided with a clamping device for connecting with the puncture needle guide device. connection device. Through the provided puncture needle guide device and depth control device, the position of the puncture needle in the puncture guide cylinder can be conveniently limited, so that during the operation, the puncture needle can be locked according to the treatment needs, and the doctor's hands can be released for other diagnosis and treatment operate. The depth control device can be easily installed and removed during the operation without affecting the ultrasonic detection and puncture operation.

Description

technical field [0001] The invention relates to the field of interventional ultrasonic instruments in medical instruments, in particular to a long-handle probe interventional ultrasonic puncture depth control device. Background technique [0002] Interventional ultrasound (interventional ultrasound) is a technology developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment. It is the extension and development of the clinical application of ultrasound. Its main features are: Under dynamic monitoring or guidance, the puncture needle or catheter can be accurately inserted into the lesion, cyst cavity or pipeline structure by direct percutaneous puncture, and various puncture biopsy, angiography, drainage, drug injection and other operations can be completed. Compared with surgical operations, this technology has the advantages of less trauma, faster postoperative recovery, and accurate diagnosis and treatment effects. It is widely...

AI Technical Summary

Problems solved by technology

[0006] 3. During biopsy of small lesions, changes in the depth of the puncture needle cause the puncture needle to deviate from the lesion, resulting in failure of biopsy

[0007] 4. The internal blood supply is rich and special parts, such as: throat, thyroid and parathyroid glands, liver hilar and other lesions during biopsy and ablation treatment, if the puncture depth is too deep, the surrounding trachea, esophagus, recurrent laryngeal nerve, Damage to important structures such as the portal vein, and shallow puncture depth may lead to incomplete ablation treatment

However, the use of this structure still requires manual adjustment by the doctor, which still has a high degree of difficulty in operation.
