Description
技术领域technical field
本实用新型涉及医疗技术领域中牙科用的器械，具体涉及微创阻生牙拔除器。The utility model relates to a dental instrument in the field of medical technology, in particular to a minimally invasive impacted tooth extractor.
背景技术Background technique
随着口腔牙槽外科微创拔牙技术的发展，直角手机在各类阻生牙微创拔除中的应用越来越广泛。但如何能够准确切割牙齿组织，又避免不伤及周围牙槽骨和重要的血管和神经等软组织，从而减少术中出血和并发症，成为微创阻生牙拔除的关键环节。With the development of minimally invasive tooth extraction techniques in oral and alveolar surgery, right-angle handpieces are more and more widely used in minimally invasive extraction of various impacted teeth. However, how to accurately cut tooth tissue without injuring soft tissues such as the surrounding alveolar bone and important blood vessels and nerves, thereby reducing intraoperative bleeding and complications has become a key link in minimally invasive impacted tooth extraction.
阻生牙微创拔除术中，医术者常常遇到这样的难题：未完全切透、残留部分牙体组织；切透牙体组织而又附带伤及周围组织。目前临床上，即使具有丰富临床经验的高年资医生，也很难保证每次都能成功实现：既能准确切割牙齿组织，但又不伤及周围和深层的牙槽骨和软组织，是否成功完全依靠操作者主观经验，重复性差、可操作性差。因此，临床术者常采用下列方法拔除阻生牙，即：在切割牙冠时，从牙体中央开始，在颊(唇)侧、舌(腭)侧和下方故意残留薄层牙体组织不切穿，然后用拔牙挺轻撬把牙齿分成两部分，最后再分别拔除。此方法的优点是：不伤及周围骨、血管和神经；缺点是：切割不彻底，分离的牙冠在牙窝内可松动、转动，但仍无法取出，需要二次切割。尤其在正畸需要拔除牙根未完全形成的埋伏阻生牙时，拔牙窝出口较小，此方法局限性甚为明显。因此，能够准确固定松动的牙齿、分离和保护周围正常组织成为手术成功的关键环节。In the minimally invasive extraction of impacted teeth, medical practitioners often encounter such problems: incomplete cutting, leaving part of the tooth tissue; cutting through the tooth tissue and incidentally damaging the surrounding tissue. At present, in clinical practice, even senior doctors with rich clinical experience can hardly guarantee success every time: whether the tooth tissue can be cut accurately without damaging the surrounding and deep alveolar bone and soft tissue, is it successful? Relying entirely on the subjective experience of the operator, the repeatability and operability are poor. Therefore, clinical operators often use the following methods to extract impacted teeth, that is, when cutting the crown, starting from the center of the tooth, deliberately leaving a thin layer of tooth tissue on the buccal (lip) side, tongue (palatal) side and below. Cut through, then use a tooth extraction jerk to gently pry the tooth into two parts, and finally extract them separately. The advantage of this method is that it does not damage the surrounding bones, blood vessels and nerves; the disadvantage is that the cutting is not thorough, and the separated crown can be loosened and rotated in the socket, but it still cannot be taken out, requiring a second cut. Especially when orthodontics needs to extract impacted teeth whose roots are not fully formed, the outlet of the extraction socket is small, and the limitation of this method is very obvious. Therefore, being able to accurately fix loose teeth, separate and protect surrounding normal tissues has become a key link for successful surgery.
对这一问题，目前，医术者常采用増隙器或小骨膜剥离器，撬起并固定松动的牙齿，从而实现切割目的。増隙器或小骨膜剥离器能够撬起牙齿，使其与下方的牙槽骨产生一定的距离，从而降低误伤牙槽骨和下牙槽神经管的可能性。但不足点是：1、増隙器固定作用差，不能分隔牙齿颊侧和下方牙槽骨以及周围软组织。2、小骨膜剥离器前端呈圆钝形，深入牙齿与牙槽骨之间，撬动牙齿功能差。3、手术操作者，一手持手机，一手持口角牵引器(口镜、大骨膜剥离器等)，另一助手把持増隙器或小骨膜剥离器需，严重影响术者涡轮手机的操作视野，增加操作的难度和降低了操作的准确性，增加了伤及周围牙槽骨、邻牙和软组织的风险性。To this problem, at present, the doctor often adopts gap increaser or small periosteum stripper, pries up and fixes the loose tooth, thereby realizes cutting purpose. Gap extenders or small periosteal strippers can pry the teeth a certain distance from the underlying alveolar bone, thereby reducing the possibility of accidentally injuring the alveolar bone and inferior alveolar canal. But the weak point is: 1, the fixation effect of the gap expander is poor, and the alveolar bone and surrounding soft tissue cannot be separated from the buccal side of the tooth and the lower alveolar bone. 2. The front end of the small periosteal stripper is round and blunt, and penetrates into the space between the tooth and the alveolar bone, and the function of prying the tooth is poor. 3. The operator holds a mobile phone in one hand, a tractor (mouth mirror, large periosteum stripper, etc.) Increase the difficulty of the operation and reduce the accuracy of the operation, increasing the risk of injury to the surrounding alveolar bone, adjacent teeth and soft tissue.

具体实施方式Detailed ways
如图1所示，该微创阻生牙拔除器包括连接为一体的手柄1、杆部2和头部3，拔除器呈S形，这种形状的设置，可以达到牵拉口角和颊侧牙龈粘骨膜瓣的目的，同时也比较适合人体口腔内的构造。As shown in Figure 1, the minimally invasive impacted tooth extractor includes a handle 1, a rod 2, and a head 3 that are connected as one. The purpose of the gingival mucoperiosteal flap is also more suitable for the structure of the human oral cavity.
头部3呈勺状，这种结构的独特设置能够很好的固定松动的牙齿，能分隔牙齿和下方牙槽骨以及周围软组织；同时将勺状头部的最前端设置成尖状，利于深入牙齿与牙槽骨之间，能发挥分离和撬动的作用。The head 3 is spoon-shaped, and the unique setting of this structure can fix loose teeth well, and can separate the teeth from the alveolar bone below and the surrounding soft tissues; Between the tooth and the alveolar bone, it can play the role of separation and prying.
为了满足拔除器符合人的口腔结构以及方便操作者手持拔牙器操作，杆部2由上至下依次由弯曲部21、直线部22和颈部23组成，且弯曲部21的长度为2cm，直线部22的长度为4cm，颈部23的长度为0.5cm；将手柄1的长度设置为10cm，杆部2长度设置为6.5cm。In order to meet the requirement that the extractor conforms to the human oral cavity structure and facilitate the operation of the operator holding the extractor, the rod part 2 is composed of a
为了适合不同大小牙齿的拔出，将拔牙器的头部3横径可以设置为0.8cm、0.6cm和0.4cm三种尺寸。In order to be suitable for extracting teeth of different sizes, the head 3 transverse diameter of the tooth extractor can be set to three sizes of 0.8cm, 0.6cm and 0.4cm.
该微创阻生牙拔除器进行阻生牙拔除如下：医疗人员用左手将该拔除器的头部3前端尖状插入牙槽骨与牙齿之间，向外牵拉手柄端，达到三方面的目的：牵拉口角；分离了牙齿周围牙龈组织瓣；分离了牙齿和牙槽骨。The minimally invasive impacted tooth extractor performs impacted tooth extraction as follows: the medical staff uses the left hand to insert the pointed front end of the head 3 of the extractor between the alveolar bone and the teeth, and pulls the handle end outward to achieve three-dimensional Purpose: To pull the corner of the mouth; to separate the flap of gingival tissue around the tooth; to separate the tooth and alveolar bone.
医疗人员用右手使用直角手机牙钻切割牙体组织，边切割边用左手向下插入该器械并撬动牙齿，使该器械头部3包绕牙体组织，从而进一步固定和隔离牙齿。由于器械在牙齿的颊侧和下方，即使手机牙钻切透牙体组织，也不会伤及周围骨组织。The medical personnel use the right-angle mobile phone dental drill to cut the tooth tissue with the right hand, insert the instrument downward with the left hand while cutting and pry the teeth, so that the head 3 of the instrument wraps the tooth tissue, thereby further fixing and isolating the teeth. Since the instruments are on the buccal and lower sides of the teeth, even if the mobile phone drill cuts through the tooth tissue, it will not damage the surrounding bone tissue.
医疗人员用左手握持该器械，根据预期的设计，切开牙体组织，分块拔除牙体组织。The medical staff holds the instrument with the left hand, cuts the tooth tissue according to the expected design, and extracts the tooth tissue piece by piece.
