Detailed Description
In order that the present disclosure may be more readily and clearly understood, reference will now be made in detail to the present disclosure as illustrated in the accompanying drawings.
Example 1
The multi-mode ultrasonic electrocardio-endoscope diagnosis and treatment instrument is opened, the ultrasonic probe 4 is connected, the ultrasonic control on the display 6 is clicked, the ultrasonic mode is selected, the ultrasonic probe 4 is used for searching the blood vessel (the important vein is selected here) after the upper arm of the patient is coated with the ultrasonic couplant, the position of the ultrasonic probe 4 is adjusted after the blood vessel is found, the ultrasonic probe is perpendicular to the blood vessel, the gain is adjusted, the ultrasonic signal is amplified and reduced, and the clear image is obtained from the display 6. After the measurement mode is selected to measure the pipe diameter and the depth of the blood vessel, a 21G ultrasonic probe puncture bracket is arranged on the ultrasonic probe 4, the direction of a needle groove is vertical to the direction of the probe, a puncture needle is inserted into the needle groove to puncture the blood vessel, the position of a needle point can be clearly seen in the puncture process, and visual and accurate puncture is realized. When the puncture enters the proper position, the puncture needle is separated from the needle groove of the puncture bracket, and the blood flows out from the tail end of the puncture needle, so that the puncture is successful.
Example 2
This embodiment is described by taking the case of catheter placement via a peripheral central catheter (PICC), and the implementation is as follows:
(1) Selecting an electrocardio mode on a multi-mode ultrasonic electrocardio-endoscope diagnosis and treatment instrument display 6, and respectively fixing 3 electrodes of an electrocardio lead wire 5 on the body surface skin under a left clavicle (LA), a right clavicle (RA) and a lower edge (LL) of a rib of a midline of the left clavicle to obtain a body surface electrocardiogram;
(2) Connect ultrasonic probe 4, click the supersound control on the display 6, select the supersound mode, convert the all-in-one into doppler supersound development interface, survey the upper arm vein with ultrasonic probe 4, first select the basilic vein, carry out visual puncture through the display screen, the puncture is succeeded in sending into the pipe, with lead wire jack end connection change over switch under the right clavicle, the operator is with lead wire metal clip and the interior seal wire end-to-end connection of PICC pipe, click the electrocardio control on the display 6 and switch into the electrocardio graphic mode, the seal wire can transmit internal signal of telecommunication as the electrode this moment. Because the amplitudes of the P waves in the blood vessels at different positions are different, when the tip of the guide wire is positioned in the peripheral vein, the amplitude of the electrocardiogram P wave is similar to the electrocardiogram of the body surface; when the tip of the guide wire enters the superior vena cava, the amplitude of the P wave of the guide wire is increased suddenly, when the guide wire enters the entrance of the right atrium, the amplitude of the P wave reaches the peak value, the P wave is reduced when the guide wire continues to advance, and negative or bidirectional P waves appear. The catheter tip is located in the lower third of the superior vena cava, which is the most desirable location for minimal complications. Therefore, the position of the catheter can be guided when the P wave on the electrocardiogram shown by the display 6 changes in the process of catheter placement. When the peak value of the P wave of the electrocardiogram is reached, the guide wire is positioned at 1/3 of the position below the superior vena cava, at the moment, the catheter is withdrawn by 1.5-2.0cm, and the catheter can be positioned at 1/3 of the position below the superior vena cava, namely the optimal catheter placement position.
Example 3
In this embodiment, the lacrimal passage drainage tube is taken as an example for illustration, and the content is as follows:
and clicking an ultrasonic control on a display 6 of the multi-mode ultrasonic electrocardio-endoscope diagnosis and treatment instrument to select an ultrasonic mode. Firstly, dilating punctum by a punctum dilator, probing lachrymal sac by the right-hand ultrasonic probe 4, displaying lachrymal sac images on the display 6, simultaneously inserting the lacrimal probe into the lacrimal passage through the punctum by the left hand, displaying complete strip-shaped images in the ultrasonic images if the lachrymal sac part is not blocked, and displaying the complete strip-shaped images after probing. When the lacrimal probe passes through the lacrimal canaliculus and the lacrimal sac, the probe is turned upwards by 90 degrees to probe the nasolacrimal duct and then enter the inferior nasal passage. And continuously carrying out ultrasonic exploration on the lacrimal passage part to avoid the formation of false canals. Then, click 6 nasolacrimoscope controls on the display, switch over to the nasolacrimoscope development mode, connect nasolacrimoscope 3, insert the nasolacrimoscope optic fibre in the nasal cavity, through the image in the display 6 display nasal cavity, take out the lacrimal passage probe from the nasal cavity with the drag hook under the visual condition.
The multi-mode ultrasonic electrocardio-endoscope diagnosis and treatment instrument improves the operation accuracy, can effectively avoid the formation of false tracts, reduces the pain of patients and scars. Especially, compared with the current blind hook, the operation of taking out the probe from the inferior nasal passage under the visual condition reduces the nasal bleeding probability of the patient, and even the medical care personnel with less experience can smoothly complete the operation under the visual condition.
