A Multi-Adjustable Ultrasonic Needle

Abstract

The invention relates to a multi-adjustable ultrasonic needle, which belongs to the field of medical devices and solves the problems that the existing ultrasonic needle technology has high requirements for the stability of the doctor's hand and the difficulty of the operation, and when the patient is unconscious or When the deviation occurs due to collision or other reasons, it will cause the puncture needle to deviate in the diseased tissue, and cause the problem of tearing the wound formed by puncture; this solution includes the ultrasonic needle and the adsorption frame installed on the side of the ultrasonic needle, the adsorption frame It is used for adsorption and fixation between the ultrasonic needle and the patient to keep the ultrasonic needle and the patient in a relatively static state. The ultrasonic needle includes a syringe, a needle assembly and a puncture assembly. The needle assembly is set to switch between the working state and the hidden state. The puncture assembly is used for operation by a doctor to drive the needle assembly to switch between the working state and the hidden state, and the operation modes of the puncture assembly include a coarse adjustment mode and a fine adjustment mode.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-adjustable ultrasonic needle. Background technique [0002] Intracranial hematoma is often secondary to cerebrovascular accident and craniocerebral trauma. If it cannot be removed in time, the mass effect caused by the severe increase in intracranial pressure and the toxic edema of surrounding brain tissue can lead to a series of irreversible injuries such as brain herniation and nerve damage. However, traditional craniotomy can cause risks such as brain tissue damage, ventricular septal pressure difference, and postoperative infection. Therefore, in the existing technology, the ultrasonic needle technology emerged as the times require, which is different from the general ultrasonic irradiation outside the lesion. In the treatment method, the piezoelectric ceramic transducer is placed at the rear, and a front horn is used to transmit the energy and amplitude to the need...

AI Technical Summary

Problems solved by technology

[0003] When the ultrasonic needle is used, the doctor needs to hold the ultrasonic needle, puncture the patient's skin tissue through the puncture needle, reach the diseased tissue, remove cerebral hematoma, etc. During use: 1. The stability of the doctor's hand is required to be high, and no Hand shaking and other phenomena increase the difficulty of the doctor during the operation; 2. During the operation, although the patient has been anesthetized, but when the patient deviates due to unconsciousness or collision, etc., the puncture needle will deviate in the lesion tissue. At the same time, it will also cause the wound formed by puncture to tear; generally speaking, when the existing ultrasonic needle is used, there are problems such as high requirements for doctors and high surgical risks. Therefore, the present invention proposes a multi-function Adjustable ultrasonic needle
