本发明涉及医疗用具领域，尤其涉及一种口腔种植手术用手术刀及其操作方法。The invention relates to the field of medical appliances, in particular to a scalpel for oral implant surgery and an operating method thereof.
背景技术Background technique
种植牙是牙列缺失和牙列缺损最常用的治疗手段之一，种植牙包括种植外科部分和种植修复部分，种植体经种植手术植入牙槽骨内，通过骨结合机制与牙槽骨形成良好的结合，支持种植牙的上部修复结构。Dental implants are one of the most commonly used treatment methods for dentition loss and dentition defects. Dental implants include implant surgery and implant restoration. Implants are implanted into alveolar bone through implant surgery, and form with alveolar bone through osseointegration mechanism Good combination to support the superimposed prosthetic structure of the implant.
成功的种植手，要求术者必须具备良好的解解剖生理知识和娴熟的外科技术，切开是种植手术开始的第一步，也是手术医生必须掌握的最基本的技能，也是种植一期手术和种植二期手术最常用的操作步骤，手术刀片是切开的最基本的器械，刀片的灵巧度直接影响着手术的进程，尤其在后牙缺牙区，由于操作视野，患者开口度，及手术刀片角度的影响，常导致切口不能按设计的切口切开，影响术者的翻瓣和手术的进一步进行。Successful implant surgery requires the operator to have good knowledge of anatomy and physiology and skilled surgical techniques. Incision is the first step in implant surgery, and it is also the most basic skill that surgeons must master. The most commonly used operation steps in the second-stage implant surgery. The surgical blade is the most basic instrument for incision. The dexterity of the blade directly affects the progress of the operation, especially in the edentulous area of the posterior teeth. The impact of the blade angle often causes the incision to not be cut according to the designed incision, which affects the flapping of the surgeon and the further progress of the operation.
目前现有手术刀片种类也有很多，按其形态可分为圆刀、弯刀及三角刀等；按其大小可分大刀片、中刀片和小刀片。根据不同的手术部位也有很多不同的刀柄设计，用于浅表组织的切割的3#刀柄、用于切开皮肤的4#刀柄、用于切割深部，精细(深刀)组织的7#刀柄、用于眼科，耳鼻喉科的9#刀柄等，临床上应用最多为一次性不锈钢的材料，临床有些患者会对金属过敏，限制了手术过程，在显微外科和整形外科手术中，金属刀片切割后会引起明显的疤痕。Existing surgical blade kind also has a lot at present, can be divided into circular knife, machete and triangular knife etc. according to its shape; Can be divided into large blade, medium blade and small blade according to its size. There are also many different knife handle designs according to different surgical sites, 3# knife handle for cutting superficial tissue, 4# knife handle for cutting skin, and 7# knife handle for cutting deep and fine (deep knife) tissue. #Knife handles, 9# knife handles used in ophthalmology, ENT, etc., are mostly used in clinical practice as disposable stainless steel materials. Some clinical patients are allergic to metals, which limits the surgical process. It is used in microsurgery and plastic surgery. In , metal blades can cause noticeable scarring after cutting.
种植手术是口腔内进行的，由于患者开口度和操作视野的限制，后牙区的切开有时因为没有专用配套的刀柄和刀片，往往给术者带来很多不便，有些金属过敏患也不能应用金属刀片。Implant surgery is carried out in the oral cavity. Due to the limitation of the patient's opening and the operating field of view, the incision in the posterior tooth area sometimes does not have a special matching handle and blade, which often brings a lot of inconvenience to the operator, and some patients with metal allergies cannot. Apply a metal blade.
