Description

Medical body surface ultrasonic positioning and marking device

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a medical body surface supersound location marking device.

Background

Precision surgery is the direction of the future in medicine. At present, an operation is to directly puncture and fix a puncture needle to the center of a focus under the guidance of ultrasound for untouchable soft tissue masses, particularly breast masses, but the operation is performed for a plurality of times under local anesthesia before an operation because of invasive operation, so that the pain, psychological burden and cost of a patient are increased, the bleeding probability after puncture is increased by puncture due to the puncture of a steel needle in a body, and the risk of high cost and perilescence caused by the fact that the puncture needle is broken and is difficult to take out occasionally is increased.

In fact, most hospitals adopt a non-invasive body surface positioning method at present, which can basically meet clinical requirements for body surface focuses, but the existing method is easy to generate deviation, and especially the deviation of deeper focuses can cause the problem of insufficient operation accuracy. When the focus is observed by ultrasound, according to clinical experience, the center of the marked focus is directly pressed by fingers at the center of an ultrasonic probe, and the position to be marked is drawn by a marker pen after a couplant is wiped off. Because the ultrasonic probe needs to be removed and then marked during operation, the marking position is usually shifted at the interval of moving the probe, smearing the couplant and marking by a pen, and even the time is delayed because the original pressing mark is not clear and the focus needs to be searched again by ultrasonic waves; this procedure may not be as large a shift as possible for superficial lesions, but for deeper lesions, particularly large relaxed breasts, the shift in the body surface positioning may be more exaggerated, creating a bias of millicentimetres, a spurious discrepancy sometimes resulting in a significant enlargement of the operative resection area, increasing the ineffective trauma of the patient's operation.

At present, two positioning methods are commonly used in the market for accurate positioning: the first steel needle puncture method is to puncture the central part of the focus from the side of the ultrasonic probe under ultrasonic observation after local anesthesia is applied before or on the day of operation. The utility model has the advantages that the utility model can be directly punctured into the tumor mass to accurately reflect the center position of the focus, and the unfavorable position is invasive operation, which can increase pain, panic and anxiety of the patient during the operation; the puncture needle also increases the medical expense; the side part penetrates into the position not right above the operation path to increase the length of the operation path; in addition, the increased needle surgery results in bleeding, infection and complications of broken needle leading to difficult removal. The second non-invasive body surface positioning method adopted at present is not only inefficient but also prone to deviation due to complicated and dragged processes, and often enlarges the invalid range of the operation during the conventional operation of non-ultrasonic monitoring in the operation, and increases the injury of patients (and people know that more than half of patients adopt the conventional operation during the operation of tumor mass which can not be touched by mammary gland, on one hand, some focuses contain coarse calcification or focus beside mammary gland, and are not suitable for the minimally invasive operation guided by ultrasonic in the operation, on the other hand, surgical instruments adopted by the minimally invasive operation are disposable, self-cost and expensive in price).

No similar devices were found by searching for prior patents.

Therefore, in summary, there is a need for a novel medical body surface ultrasonic positioning and marking device which is simple in operation, convenient to use, capable of marking the center of a focus and a planned puncture point or even the edge of the focus right below a body surface most accurately and quickly under the condition of no wound, and suitable for body surfaces including mammary glands, untouchable masses, lymph nodes or other focuses, and other body surfaces needing ultrasonic guided percutaneous puncture of the focus to be positioned and marked; however, no report is found about the novel medical body surface ultrasonic positioning and marking device.
