Description

Oral cavity strutting arrangement is used in excision of wicresoft's apex
Technical Field
The invention relates to the technical field of oral surgery equipment, in particular to an oral cavity supporting device for minimally invasive apical resection.
Background
Apical resection is a surgical procedure for promoting the healing of periapical disease by scraping the diseased tissue periapical and excising the infected root tip, treating the stump of the root tip, and depositing calcified material by the organization of blood clots. Partial additional or other operations such as root tip scraping, root tip breaking and root canal inverted filling are also generated on the basis of the root tip resection, and a limiting device is required to limit and fix the lips of a patient in the root tip surgery process, so that the operation is convenient to carry out.
Patent CN201911314214.5 discloses an oral cavity supporting device for minimally invasive root tip excision, which aims at the need of micro root tip surgery for retaining the affected tooth. Soft tissue flap turning is carried out under a microscope, sclerotin is removed, a diseased root tip is exposed, tissues around the root tip and a pulp cavity are cleaned, the diseased root tip is cut off, a root canal system at the root tip is sealed by special materials, finally, the diseased tooth is healed around the root tip, and the diseased tooth is reserved. When the root tip excision is performed, the lips of a patient need to be turned up, so that the gum of the patient is directly exposed, and the surgical operation of a doctor is facilitated. Most of the existing lip turning-up operations are that the lip of a patient is turned up by a medical worker holding a dial plate and is supported for a long time, so that the operation is very troublesome, and the medical worker can feel very fatigue when keeping a fixed posture for a long time; the arc-shaped shifting plate which can be replaced is arranged, so that cross infection can be avoided.
The supporting device has the following defects: 1. above-mentioned strutting arrangement is not convenient for fix according to the upper and lower width of patient's chin, can only fix the upper and lower lip that needs the operation position, can't firmly fix patient's chin, rocks easily in the operation, has fixed limitation, causes the influence to the operation, has reduced strutting arrangement's practicality. 2. Above-mentioned strutting arrangement is single-point control to the open degree control of patient's lip, is difficult to open the lip completely, and causes the damage to the lip easily, and above-mentioned strutting arrangement is not convenient for dismantle, if use same equipment to carry out oral cavity operation to the patient of difference, even if abluent clean again also has the bacterium to remain, causes cross infection easily, has reduced strutting arrangement's practicality. 3. The supporting device does not have lighting equipment, and other lighting equipment needs to be used for lighting in the operation, so that the operation efficiency is reduced, and meanwhile, the practicability of the supporting device is reduced.
