Description

Dynamic protection system for maxillary sinus perforation in root tip operation Technical Field The invention relates to the technical field of medical instruments, in particular to a dynamic protection system for maxillary sinus perforation in root tip operation. Background Dental pulp disease and periapical disease are common and frequently-occurring diseases of oral clinic, root canal treatment is the most effective and commonly-used treatment method at present, for diseased teeth which fail in root canal treatment and can not be treated again or still fail in root canal treatment, root tip operation becomes an effective means for retaining natural teeth, and the root tip operation is to cut off diseased root tips in a surgical mode and perform root canal pouring preparation and pouring filling, so that the purposes of eliminating infection and retaining diseased teeth are achieved; The maxillary sinus is the largest pair of maxillary bones on two sides of the nasal sinuses of the human body, is an air-containing cavity in the skull around the nasal cavity and is communicated with the nasal cavity, the root of the maxillary posterior tooth is adjacent to the maxillary Dou Debi, and part of the root even protrudes into the maxillary sinus, when the maxillary posterior root tip operation is carried out, in order to fully expose the pathological root tip, the maxillary sinus bottom lifting operation is required, and the maxillary Dou Debi is perforated in the process; Different from the lifting of the maxillary sinus in the oral implantation operation, the root tip operation needs to be performed with the steps of root tip excision, preparation pouring, filling pouring and the like after the maxillary sinus lifting, if the maxillary sinus perforation occurs in the operation, root tip fragments, preparation pouring fragments, infectious substances and filling pouring materials generated in the operation process can enter the maxillary sinus cavity through the perforation part to cause complications such as maxillary sinus infection, inflammation and the like, and in addition, surgical flushing liquid and oral liquid can also enter the maxillary sinus through the perforation part to cause symptoms such as choking cough, discomfort and the like of a patient, so that the operation safety and the patient experience are seriously affected; Aiming at the protection of maxillary sinus perforation in root tip operation, a hemostatic cotton ball with a traction wire is used for temporarily filling a perforation part at present, and is taken out after operation, however, the prior art has the following defects: 1. the cotton ball has limited water absorption capacity, and when the flushing liquid amount is large, liquid still possibly permeates into the maxillary sinus, so that the liquid cannot be effectively prevented from entering; 2. the traction wire needs to be led out from the operation wound, so that the operation space is occupied, and the operation field definition and operation are affected; 3. the cotton ball has difficult size selection, the perforated area cannot be completely covered by undersize, and the cotton ball is difficult to be placed through a limited bone window if the cotton ball is oversized; 4. the traction wire is in a loosening risk, and the cotton ball can slide into the maxillary sinus cavity to cause foreign matter residue, so that the cotton ball needs to be taken out by a secondary operation; 5. Cotton ball materials can generate cotton wool falling off, the cotton ball materials are left in an operation area to influence postoperative healing, and the non-degradable materials have biocompatibility risks; therefore, there is a need to develop a maxillary sinus perforation protection system for root tip surgery that can dynamically monitor, actively protect, safely and reliably, so as to overcome the above-mentioned drawbacks of the prior art. Disclosure of Invention In the summary, a series of concepts in a simplified form are introduced, which will be further described in detail in the detailed description. The summary of the invention is not intended to define the key features and essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. In order to at least partially solve the problems, the invention provides a dynamic protection system for maxillary sinus perforation in root tip surgery, which comprises an air bag, wherein the air bag is connected with an air charging device, a negative pressure suction device and a water leakage sensing device are arranged on the outer side of the air bag, the air charging device, the negative pressure suction device and the water leakage sensing device are electrically connected with a controller, and the controller is fixed on a head band assembly. Further, the air charging device comprises an air inlet pipe, one end of the air inlet pipe is fixed in the ai
