Multi-term adjustable ultrasonic needle

Abstract

The invention relates to a multi-item adjustable ultrasonic needle, belongs to the field of medical instruments, and solves the problems that in the existing ultrasonic needle technology, the requirement for the stability of the hand of a doctor is high, the operation difficulty is large, and when a patient deviates due to unconsciousness or collision and the like, a puncture needle deviates in pathological tissue, and the operation difficulty is high. And the problem of wound tearing caused by puncture is solved. According to the scheme, the device comprises an ultrasonic needle and an adsorption frame installed on the side portion of the ultrasonic needle, the adsorption frame is used for adsorption fixation between the ultrasonic needle and a patient, the ultrasonic needle and the patient are kept in a relatively static state, the ultrasonic needle comprises a needle cylinder, a needle head assembly and a puncture assembly, and the needle head assembly is switched between a working state and a hidden state. The puncture assembly is used for being operated by a doctor to drive the needle assembly to be switched between the working state and the hidden state, and the operation mode of the puncture assembly comprises 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 multiple adjustable ultrasonic needle. Background technique [0002] Intracranial hematoma is often secondary to cerebrovascular accidents and craniocerebral trauma. If it cannot be removed in time, the mass effect will cause a sharp increase in intracranial pressure and toxic edema of the surrounding brain tissue, which can cause a series of irreversible injuries such as brain herniation and nerve damage. However, traditional craniotomy can cause brain tissue damage, changes in ventricular septal pressure difference, and postoperative infection. Therefore, in the prior art, ultrasonic needle technology emerged as the times require, which is different from the general ultrasound that irradiates outside the lesion. In the treatment method, the piezoelectric ceramic transducer is placed behind, and a front horn is used to transmit the energy and amplitude to the needle tip, and...

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
