Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The embodiment of the utility model provides a positioning device that windows for oral surgery, including positioning network, fixed establishment and connecting rod 3, the fixed establishment card is solid on patient's tooth 4 and passes through connecting rod 3 with the positioning network links to each other, through fixed establishment can with the relative position of positioning network fixes, the positioning network can freely be moulding according to patient's oral cavity shape, through the positioning network refers to as the location, can make things convenient for the quick effectual affirmation position of punching and the scope of windowing of doctor.
Specifically, the method comprises the following steps:
as shown in fig. 1, in this embodiment, the fixing mechanism is a rubber dam clamp 1 which is widely used in dentistry, the rubber dam clamp 1 includes an arc-shaped bow 101 for providing elastic clamping force, clamping arms 102 disposed at both ends of the arc-shaped bow 101 for clamping teeth 4, the clamping arms 102 are provided with circular connecting holes 103, and the rubber dam clamp 1 can be positioned and fixed by inserting the working end of the corresponding clamping jaw into the connecting hole 103, spreading the rubber dam clamp 1, and clamping the clamping jaw to the neck of the corresponding tooth 4. When the rubber barrier clamps 1 are in place, the connecting holes 103 are used as jacks for connecting and fixing the positioning nets, and one positioning net is usually fixed by two rubber barrier clamps 1.
As shown in fig. 2, as a preferred embodiment, the positioning mesh is a titanium mesh 2, and the titanium mesh 2 is a planar mesh structure woven by titanium wires, because the titanium mesh 2 has the advantages of easy forming, strong plasticity, good biocompatibility, strong corrosion resistance, elastic modulus close to natural bone, etc., the mesh can be freely shaped according to the alveolar bone shape of a patient, and can keep the shape, perfectly fit the surfaces of gingiva and alveolar bone, and ensure the surgical precision. The meshes of the titanium wire mesh 2 are equilateral triangles with the side length of 5mm, so that the consistency of the distance between two adjacent nodes of the titanium wire mesh 2 can be ensured as much as possible when the titanium wire mesh 2 is plastic; and the connection node of the titanium wire mesh 2 is also integrally provided with an annular positioning hole 201, the positioning hole 201 is used as a position reference, and a doctor can accurately define the punching position of the embedded tooth and the windowing bone removal range through the positioning hole 201 by combining with CBCT, and the inner diameter of the positioning hole 201 is 1.5mm, so that a bone removal drill needle can be inserted conveniently, and the effect of assisting punching is achieved.
As shown in fig. 2, the number of the connecting rods 3 is the same as that of the rubber dam clamps 1, and there are two connecting rods, which are used for connecting two nodes on the edge of the titanium screen 2 with connecting holes 103 on the same side of the two rubber dam clamps 1 in a one-to-one correspondence manner. Specifically, taking one of the connecting rods 3 as an example, one end of each connecting rod 3 is rotatably connected with two positioning holes 201 at the edge of the titanium screen 2 at a certain interval through a revolute pair, so that the connecting rod 3 can rotate around the positioning holes 201 to adjust the angle; meanwhile, in order to prevent the connecting rod 3 from being loosened too much to influence positioning accuracy, the revolute pair adopts a tight fit connection mode, and the connecting rod 3 can be shifted to rotate only by exceeding a certain external force, so that the positioning accuracy is ensured; the other end of the connecting rod 3 is fixedly provided with a plug pin 5 matched with the connecting hole 103 of the rubber barrier clamp 1, and after the angle of the two connecting rods 3 is adjusted according to the distance between the two rubber barrier clamps 1, the plug pins 5 at the end parts of the two connecting rods 3 are inserted into the connecting holes 103 of the rubber barrier clamps 1 from the tooth crowns to the tooth root direction, so that the titanium silk screen 2 can be accurately connected with the rubber barrier clamps 1.
Further, in order to fix the titanium wire mesh 2 more firmly, the plug pin 5 is a pin made of titanium alloy, the diameter of the main body of the pin is slightly smaller than the aperture of the connecting hole 103, a chamfer is arranged at one end of the pin so that the pin can be conveniently inserted into the connecting hole 103, and a circular table top with the diameter larger than the aperture of the connecting hole 103 is arranged at the other end of the pin so as to prevent the pin from slipping out of the connecting hole 103.
It is worth mentioning that, because rubber dam clamp 1 is according to the position and the type of tooth, include that deciduous tooth presss from both sides, permanent tooth presss from both sides, preceding molar presss from both sides and the specification of multiple differences such as molar clamp, correspond, titanium silk screen 2 and connecting rod 3's size of a dimension also can carry out the adaptability adjustment according to the position of windowing and rubber dam clamp 1's connecting hole 103 diameter, thereby make the utility model discloses can be applicable to the positioning demand of windowing of various age groups and various profile of tooth patient oral surgery, the commonality is strong. As shown in figures 3 and 4, aiming at the positions of the embedded teeth and the morphological characteristics of adjacent teeth and alveolar bones, the rubber barrier clamp 1 and the titanium wire mesh 2 with corresponding sizes are flexibly selected, so that the extraction of the embedded impacted teeth and the more impacted teeth in the front teeth and the back teeth of the upper and lower jaws can be effectively met. Moreover, the device can be reused for the next patient after disinfection, can be quickly fixed and shaped according to the characteristics of different patients, and can perform immediate operation, thereby greatly reducing the economic cost and time cost of the operation.
Taking the bone removing operation of the embedded tooth as an example, the utility model has the following specific using method:
in using the utility model discloses the time, confirm according to the X line piece that the patient shot earlier that the tooth is roughly put that buries to choose for use two adjacent teeth in this region as fixed abutment, the rubber dam clamp 1 that the installation abutment corresponds, reselect the titanium silk screen 2 with big or small moderate degree, insert the bolt 5 at 2 edges of titanium silk screen and lie in the connecting hole 103 of burying tooth one side on the rubber dam clamp 1 and carry out the maintenance, press titanium silk screen 2 according to patient's alveolar bone form again, make titanium silk screen 2 laminate with the oral mucosa completely. Subsequently, the patient carries out CBCT (cone beam computed tomography) imaging examination, and the boundaries of the embedded teeth and the corresponding positioning nodes of the titanium silk screen 2 are determined according to CBCT imaging data. The titanium mesh 2 is removed while the rubber barrier clamp 1 is retained, and then the operation is performed. After the gingival flap is turned over, the sterilized titanium wire mesh 2 is worn again, and according to the previously determined positioning node, the bone removing drill needle is used for punching the surface of the jaw bone to determine the bone removing range of the embedded tooth. Finally, the titanium wire mesh 2 and the rubber barrier clamp 1 are removed, and the operation is continued, so that accurate bone removal and minimally invasive tooth extraction are realized.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
