Description
Technical Field
The invention relates to the field of radial artery application, in particular to a system and a method for selecting the thickness degree of a radial artery lumen.
Background
The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery was about 21.2cm long with an outside diameter of about 0.3cm at the beginning. After the brachial artery is divided, the patient goes downwards and outwards, passes through between the brachioradialis muscle and the circumflex muscle, then is positioned between the flexor carpi radialis and the brachioradialis muscle, and enters the nasopharynx fossa of the pars plana after the lower end of the radius obliquely passes through the tendon deep surface of the extensor hallucis longus and the extensor hallucis brevis to the back of the hand, passes through the gap of the 1 st metacarpal bone and enters the deep part of the palm, and is divided out of the main artery of the thumb, and then is anastomosed with the deep branch of the ulnar artery to form the deep arch of the palm. The radial artery is shallow between the lower end of the radius and the flexor carpi radialis tendon, and is an ideal site for palpating the pulse and performing a puncture. The radial artery has a constant two-vein tracing. Drawing a straight line from 2.5cm below the center of the antecubital fossa to the inner side of the styloid process of the radius, and taking the straight line as the body surface projection of the radial artery.
The radial artery branches as follows: (1) the radial return artery, starting from the upper segment of the radial artery, goes outward and upward and is anastomosed with the radial collateral artery, and (2) several muscular branches distributed in the extensor group of the forearm. (3) The branch of the carpometacarpal branch, which originates from the lower edge of the anterior gyral surae muscle and runs to the ulnar side, coincides with the artery with the same name originating from the ulnar artery at the deep side of the flexor tendon and joins the lateral carpal meshwork. (4) The superficial branch of the palm, which originates before the radial artery turns to the back of the hand, descends into the palm and is distributed behind the thenar muscle and anastomoses with the superficial branch of the ulnar artery to form the superficial arch of the palm. (5) The dorsal branch of the wrist, which emerges after the radial artery turns into the dorsal region of the hand, joins the dorsal carpal meshwork. (6) The metacarpal artery, which emerges before the radial artery penetrates the first interosseous dorsal muscle. The finger is divided into three branches, which are downward distributed on the two side edges of the back of the thumb and the radial edge of the back side of the index finger. (7) The major thumb artery, which originates from the radial artery after the transfer into the palm, descends through the deep side of the oblique head of the adductor muscles of the thumb to the vicinity of the metacarpal joint of the thumb and divides into two branches, which are distributed at the two lateral edges of the palm surface of the thumb. The major artery of the thumb is often connected with the superficial arch of the palm by a larger anastomotic branch, thereby forming another artery arch besides the superficial and deep arches of the palm. (8) The radial artery of the index finger, which usually originates from the major artery of the thumb, runs along and is distributed along the radial side of the index finger.

Next, the detailed steps of the method for selecting the thickness of the lumen of the radial artery according to the present invention will be further described.
The method for selecting the thickness of the radial artery lumen may further include:

And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.

the data storage equipment is connected with the color Doppler ultrasound imaging instrument and used for establishing an image database to store various heart color Doppler ultrasound images respectively corresponding to various patients to be subjected to the heart bypass surgery;
using a user input interface for receiving a heart color Doppler ultrasound image of a patient to be subjected to a heart bypass operation, which is input by a worker according to the operation of the worker, as an image to be processed;
using a contour recognition device connected with the user input interface and used for performing matching operation of a reference human heart contour on the image to be processed and taking the area with the maximum area in each matched image area as a target area only comprising a heart target;
using a volume assessment mechanism connected with the contour recognition device for assessing a physical volume of the heart of the patient about to undergo the cardiac bypass surgery, based on the received area of the target region, inputted by a staff;
using a thickness selection mechanism connected with the volume evaluation mechanism for calculating the thickness degree of the lumen of the radial artery required for bridging based on the received heart solid volume;
the use site display mechanism is connected with the thickness selection mechanism and is used for receiving and displaying the thickness degree of the lumen of the radial artery required by bridging;
wherein calculating a thickness degree of a lumen of a radial artery required for bypass based on the received heart solid volume includes: the larger the received heart entity volume is, the thicker the lumen of the radial artery required for the obtained bypass is calculated;
wherein evaluating a physical volume of the heart of the patient about to undergo the cardiac bypass surgery input by a staff member based on the received area of the target region comprises: the staff member inputs the heart solid volume of the patient to be subjected to the heart bypass surgery in proportion to the received area of the target region.
7. The method for selecting a thickness of a lumen of a radial artery according to claim 6, wherein the method further comprises:
an X-ray scanning mechanism is used for carrying out X-ray scanning on the area where the radial artery of the patient to be subjected to the heart bypass surgery is input by staff to obtain an imaging image of the radial artery.
