Hexagonal-prism-like suture needle for oral mucosa and applicationTechnical Field
The invention belongs to the field of medicine, and particularly relates to a hexagonal-like suture needle for oral mucosa and application thereof.
Background
The oral mucosa has its particularity with respect to the skin and other visceral mucosa or musculature. The oral mucosa has more types and various characteristics: chewing mucous membrane: including gum and hard palate mucous membrane, bear pressure and friction during chewing, are firmly attached, cannot move, are relatively tough and have large brittleness; coating mucosa: the mucous membranes of the lips, the cheeks, the tongue abdomen, the mouth bottom, the soft palate and the like except chewing mucous membranes and tongue back mucous membranes are softer than mucous membranes of other parts, have gland elasticity, are not easy to tear off, have certain mobility and can relieve traction force; the special mucous membrane, namely the mucous membrane of the back of the tongue, has certain extension, but the tissue is easy to tear. The particularity of the mucosa leads to the particularity and diversity of the wound, and how to use one needle to suture various oral mucosa wounds needs to develop new technology and new method, thereby saving the suture time and obtaining better healing effect.
In general, surgery in the oral cavity may involve the gingival mucosa, periodontal mucosa, alveolar mucosa, palatal mucosa, the floor of the mouth and the mucosa of the dorsum of the tongue. The conventional outpatient department of stomatology carries out the operations of planting, periodontal flap, complex tooth extraction and the like, which can involve the suture of one or two kinds of mucous membranes, and the serious oral trauma can involve the suture of various or even all the oral mucous membranes, and the conditions are complex and various.
Currently, the following categories of medical suture needles are mainly used: round needle: the cross section of the whole needle body is round, and the needle body is mainly used for soft and easily penetrated tissues such as peritoneum, gastrointestinal tract and heart tissues and has small damage when penetrating; round angle needle: is suitable for tough tissue, the tip of the needle is triangular, and the needle body part is circular; angle needle: the part from the needle point to the belt line is triangular and is used for penetrating tough and hard tissues such as fascia, skin and the like; metal wallet: the metal wallet is put into a special nail box, and a special clamp is used for clamping the metal wallet, so that the metal wallet is mainly used for suturing skin and orthopedic surgery; fifthly, no damage sewing: this type of needle is attached to the ends of the suture and is used for both vascular anastomoses and tubular or circular constructs, as well as for continuous suturing, both curved and straight, as in intestinal anastomoses and cardiac surgeries; a threading needle: has a handle, the front end of which is a flat round blunt curved needle point and a needle body, and is used when the deep tissue ligates blood vessels, which is not easy to cut and convenient to operate and is commonly used in liver surgery.
In view of the fact that different suture needles are suitable for different tissues, there are three types of suture needles commonly used in stomatological surgery at present according to clinical use conditions: round needle: the section from the needle point to the part with the line is circular, and the suture is generally used for suturing the covered mucosa, has small penetrating power and small damage, and has the defects of large resistance and increased fatigue degree of an operator due to small penetrating power; round angle needle: the tip is triangular, the needle body part is round, the penetrating power is large, the injury is small, therefore after penetrating the mucous membrane, the resistance is large in the traction process, the fatigue of the operator is increased, and the horn needle: the part from the needle point to the belt line is triangular, the penetrating power is large, the operation is fast and simple, but the wound of the tissue is torn greatly, and the tissue which is fragile and easy to tear, such as the tongue back mucous membrane, is dangerous. The three suture needles are different from the needle holes left on the mucous membrane, the wound of the round needle is hollow, and the horn needle is a triangular wound with sharp edges. The most common oral surgery is the reverse angle needle in the angle needle at present, the wound is relatively small, but the application range is still relatively limited, the left suture wound is also large, and the healing time is prolonged.
The surgical procedure typically involves both resection and reconstruction, with suturing often being the most time consuming procedure. The suturing is strictly required, including the clamping position of a needle holder, how to insert and withdraw the needle, the use of forceps and the like, and a doctor can puncture the suturing needle to a desired position through standard operation to carry out accurate alignment suturing. In particular, the oral cavity injury position is usually deep, the visual field is limited and cannot be directly observed, so that the operation difficulty of suturing is higher, and the requirement on doctors is higher.
Compared with suturing of large clinical skin, visceral organs and the like, the oral mucosa suture is characterized in that injuries often involve various mucous membranes and are located at deep positions, how to enable a suture needle to be applicable to various mucosal injuries, and the suture needle can rapidly penetrate through the mucous membranes and cause small tissue injuries, so that the wound healing time is shortened, and the oral mucosa suture is a problem to be solved urgently in the current oral clinical suture.
Disclosure of Invention
The invention provides a suture needle aiming at the defects, which breaks through the constraint of the traditional round needle and angle needle concepts, is suitable for the suture of various oral mucosa and can enable the operation to be more minimally invasive and the linear suture wound to be more easily healed.
