technical field

The embodiments of the utility model relate to the technical field of medical equipment, in particular to a tooth extraction forceps.

Background technique

Tooth extraction is the most common treatment technique in dentistry and refers to the process of separating and removing the root of a tooth and the alveolar bone. If the area of contact between the root and the alveolar bone is small, the extraction of the tooth is relatively labor-saving, such as the extraction of a loose tooth. But in most cases, tooth extraction is not so easy, and the biggest difficulty for the patient is keeping the mouth open for a long time.

To keep the patient's mouth open, doctors often put mouth-openers in the patient's mouth. However, the long-term placement and the relatively large size of the existing mouth-opening device are easy to obstruct the sight of the medical staff, making it inconvenient to observe, and at the same time, the placement process is cumbersome and inconvenient to adjust. tearing of the mouth, etc.

Detailed ways

In order to facilitate the understanding of the present utility model, the present utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element, or one or more intervening elements may be present therebetween. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions used in this specification are for illustrative purposes only.

Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field belonging to the present invention. The terms used in the description of the present invention are only for the purpose of describing specific embodiments, and are not used to limit the present invention. As used in this specification, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

Please refer to FIG. 1 , which shows a schematic diagram of tooth extraction forceps according to an embodiment of the present invention. The tooth extraction forceps includes two rotatably connected struts 10 , a rotating shaft 20 , a forceps portion 30 and a tension spring 40 . Among them, the two rotatably connected support rods 10 play the role of supporting the opening of the oral cavity like a lever, the rotating shaft 20 is the fulcrum of the support rod 10, the pliers 30 plays the role of tooth extraction, and the tension spring 40 is used to maintain the support rod 10. Opening and closing angle. Each component will be explained separately below.

Regarding the strut 10, the two struts 10 are installed like scissors. The strut 10 includes a first rod section 11 and a second rod section 12. The first rod section 11 is used to open the mouth, and the second rod section 12 is provided with a shaft. A hole in which the shaft 20 is installed. The first rod section 11 is elastically connected with the second rod section 12 . Preferably, the first rod section 11 and the second rod section 12 are connected by springs, and of course, they can also be connected by means of rubber, which will not be described in detail here in the present invention. In addition, the present brace 10 is preferably made of stainless steel or other materials, since it extends into the oral cavity, rust should be avoided. In order to facilitate the grasping of the hands of the medical staff and facilitate the application of force, a diamond-shaped pattern 13 is partially provided on the surface of the second rod segment 12 to increase the frictional force of the contact surface. Of course, other patterns may also be used in other embodiments, and the present invention is not limited thereto.

Regarding the forceps 30, it is slightly modified from the existing tooth extraction forceps. The forceps portion 30 includes a forceps head 31 and a forceps handle 32 . In order to facilitate the physician to adjust the angle of the forceps head 31 according to the position of the target tooth, the forceps head 31 and the forceps handle 32 are rotatably connected. The pliers handle 32 is provided with a through slot through which the rotating shaft 20 passes, and the pliers handle 32 is slidable relative to the rotating shaft 20 , that is, the pliers handle 32 is slidable relative to the strut 10 . In addition, the tooth extraction forceps further includes a blocking piece 50 , the blocking piece 50 is mounted on the end of the rotating shaft 20 , and the end surface of the blocking piece 50 abuts against the forceps handle 32 . Of course, in other embodiments, the blocking piece 50 can also be disposed at a distance from the clamp handle 32 , that is, the rotating shaft 20 is loosely connected with the clamp handle 32 to ensure free movement of the clamp handle 32 in multiple dimensions.

As for the tension spring 40 , it is arranged between the two second rod segments 12 , and the tension spring 40 is used to keep the two second rod segments 12 close to each other, so as to maintain the tension between the second rod segments 12 . In order to avoid interference between the tension spring 40 and the movement of the clamp handle 32 , the clamp handle 32 is provided with a shaft sleeve 33 , and one end of the tension spring 40 is connected to the shaft sleeve 33 .

The use process of the embodiment of the present utility model: the medical staff first expands the opening and closing angles of the two second rod segments 12 to reduce the opening and closing angles of the two first rod segments 11, and then extends the first rod segments 11 into the oral cavity, One end of the first rod segment 11 abuts against the wall of the interface cavity, the hand releases the force of the second rod segment 12 , and the second rod segment 12 maintains the opening angle under the action of the tension spring 40 . Adjust the posture of the forceps handle 32 so that the forceps head 31 acts on the target tooth, and the tooth extraction function can be realized by dragging the forceps handle 32 .

To sum up, the tooth extraction forceps not only covers the tooth extraction function, but also includes the function of opening and fixing the mouth, and the angle of opening the mouth is adjustable. At the same time, the relative position of the forceps 30 and the strut 10 is clear, and there is no interference, which reduces the impact on the patient. Risk of injury.
