Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a clamping forceps and a root canal surgery operation box used for tooth replantation. Background Art

[0002] Tooth replantation includes intentional replantation and autologous tooth transplantation. Intentional replantation is to extract the affected tooth with minimally invasive means and replant it back into the original alveolar socket after evaluating the root condition and removing the lesion. It is the last resort to preserve teeth with pulp and periapical diseases, and is used for difficult and complicated cases that cannot be solved by general treatment methods. Autologous tooth transplantation mainly refers to the surgical process of transplanting teeth from one location to another location in the same individual. The most common method is to transfer impacted, misplaced or ectopically erupted teeth to other alveolar sockets that require tooth extraction or missing teeth, or to surgically prepared alveolar sockets.

[0003] Among them, the "Intentional Tooth Replantation Operating Tool" disclosed in the application number "CN202123245579.2" is also an increasingly mature technology, which records "The utility model relates to the field of medical devices, and in particular to an intentional tooth replantation operating tool, including a fixing component and an immersion component, the fixing component is used to fix the ex-vivo tooth, the immersion component is used to hold physiological saline, and the fixing component and the immersion component cooperate so that the ex-vivo tooth can be immersed in physiological saline to complete the resection of the diseased root apex. The intentional tooth replantation operating tool described in the utility model is provided with the fixing component for fixing the ex-vivo tooth, thereby avoiding the sliding contact with the root surface caused by loose fixation during root canal surgery, which affects the survival rate of the ex-vivo tooth replantation. At the same time, the immersion component is provided to be used in conjunction with the fixing component, so that the ex-vivo tooth can always be immersed in physiological saline during the resection of the diseased root apex, further ensuring the survival rate of the ex-vivo tooth after replantation;

[0004] In addition, there are the following disagreements:

[0005] 1) In clinical operation, first use dental forceps to extract the affected tooth minimally invasively, and then perform root canal surgery on the affected tooth in vitro immediately, including apexectomy, root canal preparation, and root canal filling, and then reposition and fix the tooth. During the whole process, attention should be paid to protecting the periodontal membrane on the root surface, and the time of the affected tooth being out of body should be controlled within 15 minutes, otherwise the survival rate of the replanted tooth will be reduced. However, it is often difficult to fix the tooth in vitro during root canal surgery after tooth extraction. The main operation techniques are as follows: ① After extracting the tooth with dental forceps, transfer the tooth to wet gauze, hold the crown wrapped in wet gauze, or hold the crown directly, and perform apexectomy and root canal preparation and filling. After the operation, put the tooth back on the wet gauze, hold the crown of the tooth and adjust the direction of the tooth. ② After the tooth is extracted with forceps, the tooth is placed in a container, and then the tooth is transferred to a specific fixture. After the tooth is fixed, the apex resection and root canal preparation and filling are performed. After the operation, the device is released, the crown of the tooth is held and the direction of the tooth is adjusted, and the tooth is implanted back to the original extraction socket; ③ After the tooth is extracted with forceps, the forceps clamp the crown of the tooth, the doctor holds the forceps tightly, and changes the direction of the forceps so that the root is facing upward, so as to facilitate the apex resection and root canal preparation and filling. After the operation, the direction of the forceps is adjusted and the tooth is implanted back to the original extraction socket. Methods ① and ② have the transfer of the tooth from the forceps to other parts. On the one hand, the transfer process delays time, and on the other hand, it is easy to damage the periodontal membrane, affecting the prognosis. Method ③ The tooth is always clamped on the forceps, which reduces the transfer time and the risk of periodontal membrane damage during the transfer process, but the doctor needs to continuously apply force to clamp the tooth, which increases the doctor's hand fatigue and in the process of changing direction, the risk of accidentally causing the tooth to fall is greater.

[0006] 2) In addition, when performing root canal surgery outside the body of the affected tooth, it is necessary to constantly moisten the tooth with saline, and the gutta-percha debris produced during the apical preparation is easily attached to the periodontal membrane, making it difficult to clean and affecting the prognosis of cleaning.

[0015] Also included is an operating mechanism, the operating mechanism including a clamp placement box for carrying the clamp mechanism;

[0016] A placement slot for placing the clamp is provided in the middle of the clamp placement box, wherein the slot position of the placement slot is oval in shape.

[0017] As a preferred solution of the utility model: the two concave rubber clamps are sequentially adapted to the sides of the slot where the slot is placed, and the middle parts of the two concave rubber clamps are provided with a clamping groove.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1) The forceps beak and silicone clamping surface are used to clamp the patient's teeth. The silicone clamping surface increases friction. The small head design of the silicone clamping surface is suitable for all posterior and anterior teeth in the mouth. After clamping, a series of operations such as tooth removal - in vitro operation - replantation are integrated. It is adapted to the clamp placement box and the concave rubber clamp to avoid switching and transferring of multiple devices of the affected teeth, so as to reduce damage to the periodontal membrane, reduce operation time, and improve the survival rate of transplanted teeth;

[0020] 2) Pour physiological saline into the clamp placement box during root canal treatment to ensure the moistening of the periodontal membrane and allow the gutta-percha debris produced during root canal preparation to float in the physiological saline to avoid contamination of the periodontal membrane;

The liquid level of the physiological saline can be adjusted according to the total height of the clamping forceps and the tooth;

[0022] 4) By adopting a concave rubber clamp and placing the pliers into the designated slot, the corresponding pliers can be clamped and placed in place. In addition, the elastic traction of the spring is used to always keep the teeth in the beak of the pliers closed to prevent them from falling. The elastic damping state of the force spring is used to ensure that the beak of the pliers remains closed. The principle is that the beak of the clamping pliers is in a closed state in a natural state, because the reaction force of the force spring that recovers the deformation after being compressed makes the two handles move away and the two front end beaks move closer. When the beak of the pliers needs to be opened to clamp the teeth, the hand needs to apply force to bring the two handles closer and the two beaks apart. After clamping the teeth, the hand can be relaxed, and the beak of the pliers still remains clamped, thereby improving the clamping stability of the teeth. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 - Figure 5 The utility model provides a technical solution: a clamping forceps for tooth replantation, comprising a clamp mechanism 1, the clamp mechanism 1 comprises a clamp beak 11 for clamping, wherein the end of the clamp beak 11 is fitted with a silicone clamping surface 12, the middle of the edge of the silicone clamping surface 12 is fitted with a hinge shaft 13, the rear end of the hinge shaft 13 is provided with a toggle rod 14 for tilting, the middle of the rod body of the toggle rod 14 is driven with a clamping seat 15, and the side wall surface of the clamping seat 15 is sleeved with a force spring 16.

[0033] In this embodiment: the clamping seats 15 are symmetrically arranged on the inner wall of the middle part of the rod body of the toggle rod 14, and the force springs 16 are sleeved between the toggle rods 14, and the force springs 16 are adjacently sleeved on the surface of the clamping seats 15, elastically pushing the pliers beak 11 to clamp, and the spring buffering connection is used to connect them. The back side of the toggle rod 14 is provided with an arc-shaped holding mechanism 2 for hinged connection.

[0034] The applied force spring 16 ensures the elastic resistance of the lever body of the toggle lever 14, pulling so as to maintain the clamping of the silicone clamping surfaces 12 of the two clamps.

[0035] In this embodiment: the surface of the toggle lever 14 is provided with an elastic buffer, and the bottom of the toggle lever 14 is provided with an arc-shaped holding mechanism 2:

[0036] The arc-shaped gripping mechanism 2 comprises an arc-shaped gripping rod 21 respectively mounted on the end of the toggle rod 14. The outer wall surface of the arc-shaped gripping rod 21 is provided with anti-skid lines 22 to prevent the gripping hand from slipping. The groove surface of the anti-skid lines 22 is provided with gripping anti-skid grooves 23.

[0037] By using the arc-shaped holding rod 21, the anti-skid pattern 22 and the matching anti-skid groove 23, the teeth can be clamped by the corresponding silicone clamping surface 12 close to the patient's teeth.

[0038] In this embodiment, the pressure-coordinating end of the arc-shaped holding rod 21 is pulled by the toggle rod 14 , and the side wall of the arc-shaped holding rod 21 is hinged to the end of the toggle rod 14 .

[0039] By using the toggle rod 14 and the arc-shaped holding rod 21, the rod body is pressed down to adjust, which serves as the extrusion during the manual holding stage. The elastic adaptation of the forceps beak 11 and the middle force spring 16 elastically clamps the forceps beak 11 area to ensure that the forceps beak 11 always remains closed.

[0040] In this embodiment: the arc-shaped gripping rod 21 and the surface elastic damping clamp of the designated force spring 16, the end position of the toggle rod 14 is toggled by the hinge shaft 13 to move the two jaws 11 to make the jaws 11 and the silicone gripping surface 12 remain elastically closed, the jaws 11 are in a closed state, elastically connected by the force spring 16, so that the two jaw handles are separated and the two jaws 11 are close. When the jaws need to be opened to clamp the teeth, the hand needs to apply force to make the two jaw handles close and the two jaws separate. After clamping the teeth, the hand can be relaxed, and the jaws still remain clamped, thereby improving the clamping stability of the teeth.

[0041] By using the arc-shaped holding rod 21 and the elastic adaptation buffer of the force spring 16, pressure is applied to close the area of ​​the toggle rod 14.

[0042] A root canal surgery operation box, comprising the above-mentioned clamping forceps for tooth replantation:

[0043] It also includes an operating mechanism 3, which includes a clamp placement box 31 for carrying the clamp mechanism 1;

[0044] A placement slot 32 for placing the forceps is provided in the middle of the forceps placement box 31 , wherein the placement slot 32 is oval in shape.

[0045] The clamp placement box 31 and one end of the placement slot 32 are used to achieve close fitting, which facilitates the adjustment of the clamp placement box 31 in the later stage.

[0046] In this embodiment, two concave rubber clamps 33 are sequentially adapted to the sides of the slot 32 , and a clamping groove 34 is formed in the middle of the concave rubber clamp 33 .

[0047] The concave rubber clamp 33 is used to conveniently clamp the clamp into the slot for fixation.

[0048] Step 1: Operate the clamp mechanism 1 to clamp the patient's teeth; the dentist takes out the clamp mechanism 1 from the surface of the placement slot 32, holds it on the surface of the arc-shaped gripping rod 21, and adjusts the gap between the clamp beak 11 and the silicone clamping surface 12 to the position of the patient's teeth. The patient's mouth should be opened and kept still, so that the clamp beak 11 can be smoothly placed on the surface of the patient's loose and dislocated tooth. The rotation state of the hinge shaft 13 is used to reduce the distance between the ends of the clamp beak 11 until the silicone clamping surface 12 clamps the affected tooth, and then removes the affected tooth after applying a little force (the same is true for implanted teeth, except that the tooth is clamped at the position of the clamp beak 11 from the inside of the clamp placement box 31 and then added back into the mouth);

[0049] Step 2: Avoid slipping when holding the hand end, and keep the silicone gripping surface 12 firmly to prevent the tooth from accidentally falling off;

[0050] In this stage, the toggle rod 14 is determined to be uniformly closed according to the elastic compression of the arc-shaped holding rod 21;

[0051] The specific closing force is elastically squeezed according to the clamp seat 15 and the force spring 16 on its surface. In order to ensure that the spring does not slip off, the axial squeezing of the clamp seat 15 ensures that the toggle rod 14 coordinates the elastic clamping of the pliers beak 11 and the silicone clamping surface 12;

[0052] Step 3: The teeth are clamped by the silicone clamping surface 12 and do not fall off;

[0053] At this time, the force spring 16 has sufficient elastic potential energy to hold the extracted tooth from falling off;

[0054] And the patient's teeth are always clamped to facilitate the dentist's root canal surgery treatment in the later stage;

[0055] To prevent slippage during the gripping operation;

[0056] Step 4: Placement of the overall fixture;

[0057] At this time, the personnel will place the slot 32 slot area to make the concave rubber clamp 33 have elastic reset and clamp the clamp rod area, and then the user will toggle the designated concave rubber clamp 33 between the rotating states to embed the clamping clamp rod into the specific clamp groove.

[0058] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in the field. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for technical personnel in the field to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
