Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and more specifically, to a rubber dam clamp. Background Art

[0002] During the clinical treatment of the oral cavity, root canal therapy is the most effective method for treating pulp diseases and periapical diseases. During the treatment process, it is necessary to use a rubber dam for moisture isolation to isolate the teeth so that saliva in the oral cavity does not flow into the dentist's operation area.

[0003] The Chinese utility model patent with the authorization publication number CN219354206U discloses a leak-proof rubber dam clamp, including a rubber dam clamp body. A clamp pliers placement through hole is longitudinally penetrated through the bottom of the rubber dam clamp body. An inwardly concave beak edge is provided inside the bottom of the rubber dam clamp body. A beak contact lining strip is fixedly installed on the inwardly concave beak edge inside the bottom of the rubber dam clamp body. A tooth contact rubber column is bonded to the inner wall of the beak contact lining strip. By providing a beak contact lining strip at the inwardly concave beak edge of the rubber dam clamp body and providing a tooth contact rubber column on the beak contact lining strip, the beak contact lining strip intersects and contacts the teeth through the tooth contact rubber column. By providing a tooth contact rubber column made of silicone rubber to contact the teeth, the elasticity and deformation effect are good, so that the contact clamping is tighter, and thus it is not easy to leak. That is, the tightness between the rubber dam clamp and the teeth is improved, and the leak-proof effect is achieved, so that the medicine is not easy to penetrate into the oral cavity during treatment, and the inconvenient operation of using a sealant is avoided.

[0004] In the above structure, since the lengths of the side clamping arm plate and the beak contact lining strip are fixed, the adaptation effect is not good when clamping and isolating teeth of different lengths. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a rubber dam clamp. The utility model can adapt to teeth of different lengths by changing the lengths of both ends of the isolation member, and has good practicability.

[0063] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0064] Embodiment 1

[0065] Refer to Figures 1-4 , the rubber dam clamp 100 includes: an isolation member 101, a clamping group 102, and a ferrule 103; the isolation member 101 is configured in a U shape and has elasticity, and the elasticity of the isolation member 101 is in the outward expansion direction. The thickness of both ends of the isolation member 101 is greater than the thickness of the middle of the isolation member 101, so that the clamping group 102 and the ferrule 103 can be firmly fixed at both ends of the isolation member 101; the clamping group 102 is provided on the isolation member 101 and is used to squeeze the isolation member 101 to make both ends of the isolation member 101 move closer to the middle direction; the ferrule 103 is provided at both ends of the isolation member 101, and the ferrule 103 is made of rubber.

[0066] When using the rubber dam clamp 100, the doctor pinches the clamping group 102 tightly, so that the clamping group 102 no longer squeezes the isolation member 101. Both ends of the isolation member 101 expand outward, and the opening of the isolation member 101 becomes larger. Then, the isolation member 101 is clamped onto the tooth to be isolated, and the middle part of the isolation member 101 is embedded into the gap between two adjacent teeth. Then, the clamping group 102 is released, and the clamping group 102 is allowed to apply pressure to both ends of the isolation member 101 again, so that the opening of the isolation member 101 becomes smaller and the tooth is clamped.

[0067] By pinching and releasing the clamping group 102, the rubber dam clamp 100 can be quickly clamped onto or removed from the tooth, and the operation is convenient and fast.

[0068] The isolation member 101 is composed of an insertion part 101b and a fixing part 101c. The insertion part 101b is flat and U-shaped as a whole, so that the insertion part 101b can be inserted between the gaps of adjacent teeth; the fixing part is integrally formed at both ends of the insertion part 101b, and the thickness of the fixing part 101c is greater than the thickness of the insertion part 101b. The ferrule 103 is sleeved on the fixing part 101c.

[0069] The clamping group 102 includes: a first hand grip 102a, a second hand grip 102b, an elastic member 102c, and a support rod 102d; the first hand grip 102a is integrally formed on the separator 101 at one end of the separator 101; the second hand grip 102b is integrally formed on the separator 101 at the other end of the separator 101, and is mirror - set with the first hand grip 102a. There is a certain distance between the connection of the first hand grip 102a and the separator 101 and the end of the separator 101, and the first hand grip 102a is integrally constructed in an S shape.

[0070] The support rod 102d is horizontally slidably arranged on the second hand grip 102b, located at the lower middle of the second hand grip 102b. An activity hole 102e for the horizontal sliding of the support rod 102d is opened on the first hand grip 102a. The activity hole 102e is in a long - strip shape and extends along the length direction of the first hand grip 102a, so that the support rod 102d can swing along the length direction of the first hand grip 102a in the activity hole 102e. There are limit pieces 102f at both ends of the support rod 102d, and the limit pieces 102f at both ends of the support rod 102d are respectively in contact with the outer walls of the first hand grip 102a and the second hand grip 102b; the elastic member 102c is a spring, the elastic member 102c is sleeved outside the support rod 102d, and both ends of the elastic member 102c are respectively in contact with the inner walls of the first hand grip 102a and the second hand grip 102b, and the elastic force of the elastic member 102c is much greater than the elasticity of the separator 101.

[0071] The doctor tightly pinches the ends of the first hand grip 102a and the second hand grip 102b that are far from the separator 101, so that the ends of the first hand grip 102a and the second hand grip 102b that are far from the separator 101 approach each other. At this time, the elastic member 102c contracts, and the self - elasticity of the separator 101 causes the ends of the first hand grip 102a and the second hand grip 102b that are close to the separator 101 to move away, realizing that the opening of the separator 101 becomes larger. After the separator 101 is sleeved onto the tooth, the doctor releases the first hand grip 102a and the second hand grip 102b, and the elastic member 102c resets. At this time, the first hand grip 102a swings under the action of the elastic member 102c. The end of the first hand grip 102a that is far from the separator 101 moves in the direction away from the second hand grip 102b, and the end of the first hand grip 102a that is close to the separator 101 moves in the direction close to the second hand grip 102b, pressing the separator 101 tightly, so that the opening of the separator 101 becomes smaller, and the separator 101 clamps the tooth.

[0072] An embedding groove 101a is opened on the fixing part 101c, and the embedding groove 101a is a dovetail groove. The ferrule 103 is snapped into the embedding groove 101a.

[0073] The ferrule 103 is composed of an embedding part 103a and a sleeve part 103b. The embedding part 103a has the same shape as the embedding groove 101a and is embedded therein. The sleeve part 103b is integrally formed on the embedding part 103a, and the sleeve part 103b semi-wraps both ends of the spacer 101.

[0074] When installing or replacing the ferrule 103, the doctor aligns the embedding part 103a with the embedding groove 101a and then pushes it into the embedding groove 101a to complete the installation of the ferrule 103. When disassembling the ferrule 103, the doctor pushes the ferrule 103 to make the embedding part 103a slide out of the embedding groove 101a to complete the separation, realizing the disassembly and assembly of the ferrule 103, so that the doctor can replace ferrules 103 of different specifications to adapt to the teeth according to different tooth sizes and other situations.

[0075] Embodiment 2

[0076] Refer to Figure 5 The clamping group 102 includes: a connecting rod 202f, a fixing member 202a, a first pull rod 202b, a second pull rod 202c, a third pull rod 202d, and a driving member 202e. The connecting rod 202f is fixed to both ends of the spacer 101. The fixing member 202a is U-shaped and elastic. Both ends of the fixing member 202a are respectively fixed to the connecting rod 202f at both ends of the spacer 101, and the opening direction of the fixing member 202a is the same as the opening direction of the spacer 101. The first pull rod 202b is hinged to one end of the fixing member 202a. The second pull rod 202c is hinged to the other end of the fixing member 202a. The third pull rod 202d is vertically slidably disposed on the fixing member 202a, located in the middle of the fixing member 202a. One end of the third pull rod 202d away from the first pull rod 202b has a thread. The driving member 202e is threadedly connected to the third pull rod 202d, located on the side of the third pull rod 202d away from the first pull rod 202b, and the driving member 202e abuts against the lower end outside the fixing member 202a.

[0077] When using the rubber dam clamp 100, the doctor rotates the driving member 202e to move the third pull rod 202d towards the first pull rod 202b, increasing the angle between the pull rod and the second pull rod 202c, and increasing the distance between the end of the first pull rod 202b away from the second pull rod 202c and the end of the second pull rod 202c away from the first pull rod 202b, releasing the elasticity of the separator 101 and achieving an increase in the opening of the separator 101. Place the separator 101 on the tooth to be isolated and wrap the tooth. Then reverse the driving member 202e to drive the third pull rod 202d to move away from the first pull rod 202b, reducing the angle between the first pull rod 202b and the second pull rod 202c, and reducing the distance between the end of the first pull rod 202b away from the second pull rod 202c and the end of the second pull rod 202c away from the first pull rod 202b, pulling the two ends of the separator 101 closer to make the opening of the separator 101 smaller and clamping the tooth.

[0078] The driving member 202e is threadedly connected to the third pull rod 202d. Through the self-locking of the threaded connection, it is not easy for the separator 101 to fall off after clamping the tooth.

[0079] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
