Description

Auxiliary supporting device for puncture and ultrasonic probe matching use

Technical Field

The invention belongs to the technical field of medical equipment, and particularly relates to an auxiliary supporting device for matching puncture with an ultrasonic probe.

Background

The ultrasonic guided puncture tube placing technology is widely applied to the current medical system, the puncture tube placing technology under ultrasonic guidance is one of the important components of interventional ultrasound, in clinical use, a puncture needle can be guided to enter a patient body for interventional therapy through the matching of an ultrasonic probe image and an ultrasonic probe puncture frame, in brief, the puncture operation of a target focus is carried out in real time through matching of an ultrasonic image, so that a punctured drainage tube is kept, the puncture drainage is a very common treatment means in clinic, and particularly the puncture tube drainage is carried out under the B ultrasonic guidance or CT guidance at present. The use of puncture drainage in the clinic is most common in the following 3 conditions or diseases: 1. mainly seen in the infection of pleural effusion or the dyspnea symptom caused by a large amount of pleural effusion, the puncture of the postcostal space is adopted for drainage. 2. In case of liver cirrhosis after hepatitis and increased intra-abdominal pressure caused by a large amount of ascites, abdominal puncture is used to release the ascites so as to relieve the intra-abdominal hypertension symptoms of the patient. 3. The abdominal cavity residual effusion after the abdominal operation such as hepatobiliary, gastrointestinal or appendiceal suppuration and even secondary bacterial infection are mainly seen, and abscess is formed to cause symptoms of chilliness, fever and even blood toxicity. The puncture drainage under the guidance of B-ultrasonic is adopted to drain the pus completely, thereby achieving the purpose of healing and avoiding secondary operation.

The existing puncture tube placement technology generally adopts a 'one-step method' and a 'two-step method' to carry out ultrasonic-guided puncture tube placement work, in brief, the 'one-step method' is that puncture of a flow guide tube is carried out at the position of a patient needing puncture, the flow guide tube is internally sleeved with a metal inner sleeve tube and an inner core, so that puncture is directly carried out, after the focus is punctured, the metal inner sleeve tube and the inner core are pulled out, the 'two-step method' is that puncture is carried out through a puncture needle at the position of the patient needing puncture, after the puncture is carried out to a designated position, a needle core in the puncture needle is taken down, then the puncture needle is taken down after a metal guide wire is placed, then the puncture needle is inserted into an expansion tube along the guide wire, after the expansion tube is withdrawn, the drainage tube and the metal inner sleeve tube are sleeved, at the moment, the inner core does not need to be installed, then the assembled drainage tube is inserted into the focus along the guide wire, and after the focus is reached, the guide wire is drawn out, the inner core is taken out simultaneously to finish the puncture and tube placement work, and then the drainage tube is fixedly connected with the skin through the fixer to prevent the drainage tube from being pulled out.

In the process of matching with ultrasonic guidance, the existing puncture catheter drainage technology often needs a user to constantly hold an ultrasonic probe to ensure accurate puncture in ultrasonic development, but in the process of needle insertion, the user often moves the ultrasonic probe to monitor the punctured part in real time, so that medical staff often needs the matching of two persons to complete the position adjustment work of the ultrasonic probe and the auxiliary support work of the ultrasonic probe, therefore, in the process of supporting and positioning the ultrasonic probe, the development area is often changed by moving, the medical staff needs to readjust, time and labor are wasted, and in the process of needle insertion, sometimes the angle and the direction of needle insertion can be adjusted, and the ultrasonic probe can always ensure the current position in the process of adjustment, and cannot receive the influence of the adjustment of the needle insertion direction, when the angle and the direction of the ultrasonic probe are adjusted, the adjustment is also desired to be convenient and simple, the support is reliable after the adjustment, meanwhile, in order to avoid the situation that violent puncture or puncture may occur after a puncture route and a puncture angle are selected in the process of manual puncture by medical workers, the requirement on the speed of puncture depth is not the same under different puncture situations, the closer to a focus area, the slower the puncture speed is required by the medical workers to prevent the puncture or the injury to surrounding tissues and blood vessels, meanwhile, due to the uncertainty of manual operation, the artificial subjective deviation is generated in the determined puncture route, so that the puncture route is changed, further, inevitable injury and loss are caused to patients, and in order to ensure the accuracy degree of puncture, the problems are solved, we have then developed an auxiliary support device for use with a puncture and ultrasound probe to address the above problems.
