Description

Technical Field

[0001] The invention relates to the field of apical surgery, in particular to a moisture-absorbing paper tip set for apical surgery. Background Art

[0002] Micro-apical surgery is often used in situations including failed root canal treatment, inability to perform root canal treatment due to restorations, periapical cysts, root canal calcification, root canal separation instruments, overfilling, enlarged root canals, root fractures, failed apical surgery, apical perforation, and special root canal systems. It has a wide range of applications and a high treatment success rate. The micro-apical surgery process includes preoperative preparation; flap incision; bone removal and window opening; apical resection, scraping and inspection; root canal preparation and filling; bone cavity treatment; suturing. The main technical operations of root canal preparation and filling are: using preparation instruments to remove 3mm of infected tissue in the apical root canal, and after good root canal drying, use biological materials to fill the apical segment tightly. This step removes the infection in the irregular apical area and tightly seals the apical area. It is a key step in micro-apical surgery, and good root canal drying is indispensable. At present, apical surgery often directly uses moisture-absorbing paper tips for root canal treatment. This type of paper tip is made of pure cotton fiber, mainly divided into 02, 04, and 06 tapers, with a series of gradient apical diameters such as 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40 mm, and the length is generally 25 mm. This design takes into account the root canal morphology and drying requirements after root canal treatment. When used in apical surgery, the surgeon often needs to perform certain trimming, bending, and multiple "dip" drying operations. There are many inadaptability when using moisture-absorbing paper tips for root canal treatment directly in apical surgery.

[0003] The moisture-absorbing paper tips used for root canal treatment cannot meet the drying requirements in apical surgery. Their shape, apical diameter, length, etc. are not suitable for apical surgery. First of all, the morphology of the apex of different teeth after preparation is quite different. Most teeth have a diameter of about 0.6 mm after preparation with specific instruments, but in the case of apical fusion, the diameter can exceed 0.8 mm. However, for the maxillary first premolar with isthmus and the mandibular second molar with C-shaped root canal, the shape of the area to be dried after preparation is not a regular circle. Secondly, the field of view in apical surgery is small, and there is a large deviation in the angle of view. When drying the root canal, the straight moisture-absorbing paper tip needs to be bent at a certain angle to ensure that it reaches the apical drying area accurately, but it is difficult to grasp the precise angle by free hand bending. Furthermore, the apical surgery area is relatively moist, and a slight deviation by the doctor will cause the middle end of the moisture-absorbing paper tip to absorb water and soften in advance when it contacts other tissues, and it will not be able to exert a guiding force in the subsequent apex, increasing the "waste tip" rate. Repeated tip replacement will also increase the clinical operation time. In addition, traditional moisture-absorbing fingertips are made of pure cotton fibers, and their water absorption rate and efficiency need to be improved.

[0004] Chinese patent CN219089733U discloses a moisture-absorbing paper tip for apical surgery, which is a U-shaped structure composed of two side columns and a bottom column, the side columns and the bottom column are both circular with a diameter of 0.5-1mm, the side column length is 5-10mm, the bottom column length is 4-6mm, and the 2-4mm area on the marking area of ​​the two side columns is provided with scale lines. However, the above patent only designs a cylindrical moisture-absorbing paper tip. The cavities prepared in apical surgery are not all regular circles, and some root apices have isthmuses. Therefore, if the moisture-absorbing paper tip in the above document is used, it still needs to be trimmed and "dipped" multiple times, and there will also be the problem of increased "waste tip" rate. Moreover, the moisture-absorbing paper tip in the above document is U-shaped, and there are problems such as blocking the field of vision and inconvenience in operation. In addition, the scale in the above patent is not very useful for the moisture-absorbing paper tip used in apical surgery, because after the reverse preparation is completed, the doctor uses the microscopic caliber used in apical surgery to determine the situation after the reverse preparation, and performs reverse filling through repeated pressing. Summary of the invention

[0005] In view of this, the present invention proposes a moisture absorbing paper tip set specially used for apical surgery, which can solve the problems of narrow application range and poor adaptability of moisture absorbing paper tips in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention is configured as follows: a moisture-absorbing paper tip set for apical surgery includes a moisture-absorbing paper tip group 1 suitable for conventional tooth positions, a moisture-absorbing paper tip group 2 suitable for tooth positions with fused root canals and thick root canals, a moisture-absorbing paper tip group 3 suitable for maxillary first premolars with isthmuses and maxillary first molars with isthmuses in the mesial two buccal roots, and a moisture-absorbing paper tip group 4 suitable for mandibular second molars with C-shaped root canals; the moisture-absorbing paper tip group 1, the moisture-absorbing paper tip group 2, the moisture-absorbing paper tip group 3 and the moisture-absorbing paper tip group 4 all include a clamping part and a water-absorbing part, and the clamping part There is a prepared angle between the holding part and the water absorbing part; the water absorbing part of the moisture-absorbing paper tip group one is cylindrical with a diameter of 0.6mm; the water absorbing part of the moisture-absorbing paper tip group two is cylindrical with a diameter of 0.8mm; the water absorbing part of the moisture-absorbing paper tip group three is a columnar with a barbell-shaped cross-section; the width of the barbell-shaped cross-section is 1.7mm, the thickness at both ends is 0.6mm, and the thickness in the middle is 0.5mm; the water absorbing part of the moisture-absorbing paper tip group four is a columnar with a shuttle-shaped cross-section; the width of the shuttle-shaped cross-section is 1.7mm, the thickness in the middle is 0.6mm, and the two ends are pointed. The above-mentioned moisture-absorbing paper tip set is specially used for apical surgery and is suitable for various anatomical morphologies of surgical areas in apical surgery. For different tooth positions and root canal conditions, not only are moisture-absorbing paper tip group 1 and moisture-absorbing paper tip group 2 designed to be suitable for most tooth positions, but also moisture-absorbing paper tip group 3 and moisture-absorbing paper tip group 4 are designed for tooth positions with isthmus root canals and C-shaped root canals, which can meet the needs of all tooth positions and can be well adapted to the root canal morphology after apical inversion preparation. The "conventional tooth position" described in the present invention refers to a tooth position in which the cavity after inversion preparation in apical surgery is circular and does not have an isthmus, and most tooth positions are usually conventional tooth positions.

[0007] In order to further meet the drying angle in apical surgery, the prepared angle between the water absorbing part and the clamping part is 90°. At the same time, this angle is also more convenient for the operator to operate. In addition, the prepared angle between the clamping part and the water absorbing part of the moisture absorbing paper tip in the present invention can be manually adjusted, and the doctor can increase or decrease the prepared angle according to the actual situation.

[0008] Preferably, the length of the water absorbing portion is 3.5 mm, and the length of the clamping portion is 20 mm.

[0009] Preferably, the cross-sectional shape of the clamping portion is consistent with the cross-sectional shape of the water absorbing portion.

[0010] In order to improve the operation efficiency, a label is provided at the end of the clamping part, the label of the first moisture-absorbing paper tip group is a single bar of high-saturation yellow, the label of the second moisture-absorbing paper tip group is two bars of high-saturation yellow, the label of the third moisture-absorbing paper tip group is three bars of high-saturation yellow, and the label of the fourth moisture-absorbing paper tip group is four bars of high-saturation yellow. In this way, the surgeon can quickly identify when taking it.

[0011] To further ensure drying, the clamping part is wrapped with adhesive tape to prevent the clamping part from accidentally touching other surgical parts and getting wet due to hand shaking or other reasons during the dipping and drying process, which would make the moisture-absorbing paper tip unusable. At the same time, the paper core inside the adhesive tape still has a water-absorbing effect, which does not affect the effective water-absorbing length of the paper tip.

[0012] In order to further improve the water absorption efficiency, the moisture absorbing paper tip group one, moisture absorbing paper tip group two, moisture absorbing paper tip group three and moisture absorbing paper tip group four are all made of dust-free paper containing high molecular water-absorbing resin.

[0013] To further facilitate storage, preservation, carrying, classification and placement, the absorbent paper tip set for apical surgery also includes a storage box, the storage box has four storage spaces, each storage space is provided with an independent flip cover, and a buffer pad is provided at the bottom of each storage space, the front and rear sides of the buffer pad are against the front wall and the rear wall of the storage space, and there is a gap between the left and right sides of the buffer pad and the left wall and the right wall of the storage space, and the four storage spaces are respectively placed with the absorbent paper tip group one, the absorbent paper tip group two, the absorbent paper tip group three and the absorbent paper tip group four, the absorbent paper tip group one, the absorbent paper tip group two, the absorbent paper tip group three and the absorbent paper tip group four are placed in multiple layers, the clamping part is placed on the buffer pad, the water absorbing part is placed vertically in the gap, each layer of the absorbent paper tips is separated by sterile paper, and the water absorbing parts of the absorbent paper tips of two adjacent layers are placed in gaps in different directions.

[0014] Due to the adoption of the above technical solution, the present invention has the following advantages: The moisture absorbing paper tip set for apical surgery of the present invention combines the anatomical morphology of the surgical area in apical surgery, designs four shapes of moisture absorbing paper tips, and realizes personalized design between different tooth positions. In addition to the moisture absorbing paper tip group 1 and the moisture absorbing paper tip group 2 that can be used for most tooth positions, paper tip designs for special anatomical tooth positions are also added, including the moisture absorbing paper tip group 3 for tooth positions with isthmus root canals and the moisture absorbing paper tip group 4 for tooth positions with C-shaped root canals. These can well adapt to the root canal morphology after apical inversion preparation, thereby facilitating subsequent clinical surgical operations, increasing the success rate of the operation, reducing the pain of the patient, and thus being beneficial to the final clinical effect.

[0015] The present invention designs a clamping part for the moisture-absorbing paper tip, and performs hardening and waterproofing treatment on it, that is, dust-free paper containing a high molecular water-absorbing resin is used to improve the hardness of the moisture-absorbing paper tip, and adhesive tape is used to wrap the clamping part to achieve a waterproof function; in this way, the surrounding tissue is prevented from contaminating the paper tip, thereby avoiding waste of the paper tip, and increasing the use efficiency of the paper tip; the drying effect and cleanliness of the surgical area are increased.

[0016] The clamping part and the water absorbing part of the moisture absorbing paper tip of the present invention are pre-bent at 90 degrees, which meets the drying angle in apical surgery and is convenient for the operator to operate. The angle can also be automatically corrected according to special circumstances during the operation, and can meet the needs under different conditions while being easy to hold and use.

[0017] The moisture-absorbing paper tip of the present invention is added with a high-molecular water-absorbing resin, which has good biocompatibility, is safe and has no side effects, and has better water absorption and faster absorption rate, thereby avoiding the use of multiple moisture-absorbing paper tips and increasing the utilization rate.

[0018] 5. The present invention also provides a storage box for storing, preserving, carrying, classifying and placing four sets of moisture-absorbing paper tips. The storage space is fully utilized by stacking them. Sterile thin paper sheets are placed between each layer, which facilitates access while avoiding possible contamination. The box is suitable for clinical scenarios.

[0019] 6. The moisture absorbing paper tip kit of the present invention is based on clinical experience, combined with oral cone beam CT images of multiple patients and the actual situation in specific operations. The moisture absorbing paper tip specifications involved can be well adapted to the root canal morphology after apical inversion preparation, and has good application prospects.
