Body surface localization is very necessary for the clinical treatment operation of needle minimally invasive medicine, because needle knife minimally invasive treatment is a kind of closed surgery, to effectively avoid the neurovascular and other important organs under the knife, all must have a clear understanding of the anatomical structure within the entry point, body surface localization is to solve this problem in the needle knife medicine clinical and proposed. I. Head and neck 1. Body surface positioning of the infraorbital foramen: located below the midpoint of the infraorbital rim, equivalent to the midpoint of the line from the tip of the nose to the outer corner of the eye. 2. Body surface positioning of the chin foramen: located on the lateral side of the mandibular body, directly below the first and second premolar teeth of the mandible. 3. Body surface positioning of the facial artery: the intersection of the lower edge of the mandible and the anterior edge of the occlusal muscle is the starting point of the facial artery into the face, where the pulsation can be felt. A vertical line is made downward from the outer canthus of the eye, and then two horizontal lines are drawn upward and downward from the lateral side of the lower edge of the nose and the corner of the mouth to intersect with the previous vertical line. These two horizontal lines can divide the facial artery into three segments: the first segment of the facial artery is below the horizontal line of the corner of the mouth; the segment between the upper and lower horizontal lines is the second segment of the facial artery; the segment between the upper horizontal line and the inner canthus is the third segment of the facial artery. 4.Surface positioning of the parotid duct: it is located about 25px below the zygomatic arch and the middle 1/3 of the line from the earlobe to the midpoint between the nose and the corner of the mouth. Superficial temporal artery: It is one of the terminal branches of the external carotid artery, starting from the posterior part of the flat mandibular angle below the anterior part of the external auditory canal, passing out from the superior edge of the parotid gland, and then ascending vertically between the temporomandibular joint and the external auditory canal to above the plane of the superior orbital rim, and then dividing into two branches: frontal and parietal. 6. Body surface localization of facial nerve: When the head is turned to the opposite side, four points are taken: the point of tympanotomy, the intersection of the upper 3/5 and lower 2/5 of the posterior margin of the mandibular branch, the intersection of the upper 1/3 and lower 2/3 of the posterior margin of the mandibular branch, and the intersection of the upper 2/3 and lower 1/3 of the posterior margin of the mandibular branch, and three lines are made: ① The upper part of the line connecting the first and second points is the body surface projection of the facial nerve trunk, and the midpoint of this line is the localization point of the bifurcation of the facial nerve trunk; ② The line from the midpoint of the ① line to the third point represents the projection line of the temporal trunk of the facial nerve; ③ The line from the midpoint of the ① line to the fourth point represents the projection line of the cervical trunk. 7, the body surface positioning of the occipital nerve: the occipital nerve starts from the posterior arch of the atlantoaxial vertebrae on the medial side of the transverse process of the cardinal vertebrae, rises obliquely upward and outward, passes between the cephalic semispinal muscles, attaches to the occipital bone at the cephalic semispinal muscles, passes through this muscle, and passes through the oblique tendon and the cervical fascia (the above is the course of the occipital nerve in the deep part, and this point is about 50px from the midline in the plane of the superior collar line), reaches the subcutis, and then divides into many branches, which are distributed in the head It then divides into many branches and is distributed over most of the skin at the back of the head. 8. Body surface localization of the common carotid artery: on the right side, a line is drawn from the midpoint of the line from the angle of the mandible to the mastoid process to the sternoclavicular joint; on the left side, the lower end of the line is slightly lateral, and this line is below the upper edge of the flat thyroid cartilage as the body surface localization of the artery. 9.Surface localization of the subclavian artery: the convex upward curve from the sternoclavicular joint to the midpoint of the clavicle, the highest point of which is about 25px from the upper edge of the clavicle. 10.Surface localization of the external jugular vein: the line from the angle of the mandible to the midpoint of the clavicle. 11.Surface localization of the collateral nerve: the line from the upper and middle 1/3 intersection of the posterior border of the sternocleidomastoid muscle to the middle and lower 1/3 intersection of the anterior border of the trapezius muscle. Body surface localization of the suprascapular nerve: this nerve starts from the upper trunk of the brachial plexus (C5, C6), located on the upper side of the brachial plexus, and travels upward and outward, through the deep side of the trapezius muscle and the scapular hyoid muscle, to the scapular notch, adjacent to the suprascapular artery. This artery travels superiorly through the transverse scapular ligament to the suprascapular fossa and then turns to the infrascapular fossa. The suprascapular nerve passes inferiorly through the transverse scapular ligament to the suprascapular fossa. Here the nerve branches off to innervate the supraspinatus muscle, the shoulder joint and the acromioclavicular joint. Then the suprascapular artery bypasses the scapular neck notch to the infragonal fossa and innervates the infragonal muscle. 2.Surface location of the subscapularis artery: it starts from the axillary artery near the inferior border of the subscapularis muscle and goes posteriorly, mainly divided into the thoracodorsal artery and the rotator scapular artery. The former accompanies the thoracic dorsal nerve and is distributed to the anterior serratus and latissimus dorsi muscles; the latter travels posteriorly through the trilateral foramen to the infragonal fossa and branches out to nourish the nearby muscles.
