Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to the technical field of dental pulp pathology, and particularly relates to a microscopic root tip operation needle sleeve box.
Background
The microscopic root tip operation is one of the most commonly used methods for treating persistent periapical periodontitis at present, and mainly comprises the steps of incision, flap turning, bone removal, root tip scraping treatment, root tip excision, root tip preparation, root tip pouring filling, suturing and the like. With the development of microscopes, cone beam CT, ultrasound and biocompatible materials, the success rate of microscopic root tip surgery is increasing. However, how to accurately locate the root tip, minimally invasive bone windowing is one of the difficulties of microscopic root tip surgery. For some diseased teeth with periapical lesions, which do not penetrate through cortical bone and are thicker in the buccal bone plate, the location of the periapical area is difficult, so that excessive bone tissue abrasion during operation is often caused, the trauma of the operation area is increased, and the postoperative complications of pain, swelling and the like of a patient are caused, so that the prognosis of the diseased teeth is influenced. Second, the deviation of the operative site, particularly in the posterior maxillary dental region, may damage important anatomical structures such as the mandibular nerve canal, maxillary sinus, etc. The traditional microscopic root tip operation is to locate the root tip of an operator according to the CBCT measurement before the operation of a patient, and the operator uses a high-speed mobile phone to operate under the free hand, so that the traditional microscopic root tip operation has higher technical sensitivity. Accurate positioning of the root tip region in microscopic root tip surgery, reduction of bone removal and removal of the root tip 3mm perpendicular to the long axis of the tooth is a significant challenge to the clinician.
Along with the rapid development of the digital technology, the digital technology combines imaging, navigation design software and 3D rapid prototyping printing technology, so that the digital guide plate static navigation and dynamic navigation are increasingly applied to the dental pulp field, in particular to microscopic root tip surgery. The digital dynamic navigation technology combines a medical image three-dimensional visualization technology, a spatial positioning technology, a registration technology, software, a computer and an optical positioning device, can dynamically display the position, angle and depth of the drill needle entering the affected teeth in real time, and indicates that the circular ring can become red early warning when the drill needle reaches the pre-designed depth, so that a doctor is reminded that the drill needle reaches the preset depth at the moment. However, when the cortical bone is cut under the assistance of dynamic navigation, the drill point is easy to shake, especially when the length of the drill point blade is increased, the shake amplitude of the drill point part is increased during drilling and grinding, and the stability of root tip positioning is affected; in addition, for microscopic root tip surgery in the posterior dental region, due to the limitation of buccal oral angle and mucoperiosteal flap traction, a needle with a longer working length can cause difficulty in positioning, and the accuracy of the surgery operation is affected. The static guide plate technology utilizes CBCT and three-dimensional intraoral scanning data, analyzes the obtained data through computer software, designs and manufactures a digital guide plate by combining with 3D printing technology, and assists an operator to position the position and angle of the lesion in the root tip region through a guide hole of the digital guide plate, but has a certain limit on the depth indication of root tip excision, and the depth of an intraoperative drill needle entering the jawbone needs to be controlled depending on the analysis of the tooth CBCT before the operator operation and the accumulation of long-term operation experience, so that the intraoperative drill needle is easy to be resected insufficiently or resected excessively.
The positioning turning needle can assist in positioning the root tip, reduces shaking in the drilling and grinding process, and improves the accuracy of positioning the root tip of a microscopic root tip operation under the assistance of dynamic navigation; trephine with different diameters and length specifications can meet the operation requirements of affected teeth in different operation areas and with different cortical bone thicknesses, and the limiting part of the trephine can limit the depth of a needle for cutting or entering teeth in microscopic root tip operation assisted by a static guide plate; the annular blade-shaped tool bit of the annular cutter can assist in positioning the mucous membrane soft tissue in the annular cutting root tip region, a soft tissue passage for microscopic root tip operation is initially established, and microscopic root tip operation without flap turning is realized.
