Abstract

The utility model provides a moisture-absorbing paper tip for microscopic apical surgery, which belongs to the field of moisture-absorbing paper tips and comprises a plastic handle, a splicing mechanism, a bendable mechanism, a length adjusting mechanism and a moisture-absorbing paper tip. In the scheme, an external thread block is in threaded connection in an internal thread groove, so that a rubber sleeve and a bendable iron wire are convenient to detach and separate; when the bendable iron wire is damaged after being bent for a long time, the rubber sleeve and the bendable iron wire can be detached and replaced, the bendable iron wire can be bent completely through the characteristics of the bendable iron wire, and the included angle between the moisture absorption paper tip and the plastic handle can be adjusted by bending the bendable iron wire. Meanwhile, the inclination angle of the moisture absorption paper tip during the microscopic root tip operation is adjusted, so that the pertinence is improved, and the problems that when the moisture absorption paper tip in the prior art is used in a limited area, the moisture absorption paper tip needs to be bent into a specific angle, and due to the fact that the material of the moisture absorption paper tip is too soft, the moisture absorption paper tip cannot be bent can be solved.

Description

Technical Field

[0001] The utility model belongs to the field of moisture-absorbing paper points, and particularly relates to a moisture-absorbing paper point for microscopic apical surgery. Background Technique

[0002] Clinically, microscopic apical surgery is the last resort to solve cases such as failed non-surgical root canal treatment, recurrent apical periodontitis, true cysts of periapical lesions, or separated instruments that are difficult to remove by non-surgical methods. An important step in microscopic apical surgery is to resect the root apex, thoroughly clean and shape the apical 3 mm of the root canal, and then dry and tightly fill the prepared apical resection cavity to prevent leakage of irritants remaining in the root canal after root apex resection and retrograde preparation of the root canal, ensuring the surgical effect. Therefore, only by effectively drying the retrograde-prepared root apex can the treatment effect of subsequent root canal retrograde filling be ensured.

[0003] The authorized publication number "CN219089733U" discloses "a moisture-absorbing paper point for apical surgery, which is a U-shaped structure composed of two side columns and a bottom column. The cross-sections of the side columns and the bottom column are both circular with a diameter of 0.5 - 1 mm. The length of the side columns is 5 - 10 mm, and the length of the bottom column is 4 - 6 mm. The moisture-absorbing paper point for apical surgery provided by the utility model can quickly and fully dry the ultrasonic retrograde-prepared cavity, and can also judge the depth of the retrograde-prepared cavity, simplify the operation steps, assist in judging the situation of retrograde preparation, and thus improve the quality of apical retrograde filling."

[0004] Although the above patent improves the quality of apical retrograde filling, when the above patent is used in a restricted area, the moisture-absorbing paper point needs to be bent at a specific angle. Due to the overly soft material of the moisture-absorbing paper point, it cannot be bent, so there are limitations in using it in a restricted area. Content of the Utility Model

[0005] The purpose of the utility model is to provide a moisture-absorbing paper point for microscopic apical surgery, aiming to solve the problem that when the moisture-absorbing paper point in the prior art is used in a restricted area, the moisture-absorbing paper point needs to be bent at a specific angle, but due to the overly soft material of the moisture-absorbing paper point, it cannot be bent.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A moisture-absorbing paper point for microscopic apical surgery, comprising:

[0008] A plastic handle;

[0009] A splicing mechanism arranged at the top of the plastic handle;

[0010] A bendable mechanism arranged on the splicing mechanism;

[0011] A length adjustment mechanism, provided on the bendable mechanism; and

[0012] A moisture-absorbing paper tip, which is provided on the length adjustment mechanism.

[0013] As a preferred solution of the present utility model, the splicing mechanism includes a rotating block, an internal thread groove and an external thread block. The internal thread groove is opened at the top of the plastic handle. The external thread block is threadedly connected to the internal thread groove, and the rotating block is fixedly connected to the top of the external thread block.

[0014] As a preferred solution of the present utility model, the bendable mechanism includes a rubber sleeve and a bendable iron wire. The bendable iron wire is fixedly connected to the top of the rotating block. The rubber sleeve is fixedly connected to the circumferential surface of the bendable iron wire, and the rubber sleeve is fixedly connected to the rotating block.

[0015] As a preferred solution of the present utility model, the length adjustment mechanism includes an internal thread sleeve and an external threaded rod. The external threaded rod is fixedly connected to the same side end of the rubber sleeve and the bendable iron wire. The internal thread sleeve is threadedly connected to the surface of the external threaded rod.

[0016] As a preferred solution of the present utility model, a slot is opened at one end of the external threaded rod.

[0017] As a preferred solution of the present utility model, anti-slip grooves are opened on the surface of the plastic handle.

[0018] As a preferred solution of the present utility model, one end of the moisture-absorbing paper tip is inserted into the slot.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. In this solution, by threadedly connecting the external thread block to the internal thread groove, the rubber sleeve and the bendable iron wire are easily disassembled and separated. When the bendable iron wire is damaged due to long-term bending, the rubber sleeve and the bendable iron wire can be disassembled and replaced. Due to the characteristics of the bendable iron wire itself, the bendable iron wire can be completely bent. By bending the bendable iron wire, the angle between the moisture-absorbing paper tip and the plastic handle can be adjusted, and at the same time, the inclination angle of the moisture-absorbing paper tip during microscopic root tip surgery can be adjusted, thereby improving the strong pertinence. By providing the rubber sleeve, it can be sleeved on the surface of the bendable iron wire to isolate the bendable iron wire.

[0021] 2. In this solution, the inner threaded sleeve is threadedly connected to the outer threaded rod, so that the inner threaded sleeve can move while rotating on the outer threaded rod. By moving the inner threaded sleeve on the outer threaded rod, it can be sleeved on the tip of the moisture-absorbing paper, thereby adjusting the length of the tip of the moisture-absorbing paper exposed, so that the length of the tip of the moisture-absorbing paper exposed can be adjusted at different depths. The setting of the anti-slip groove can increase the friction force, thereby preventing hand slippage. Description of the Drawings
