Background

Tooth extraction is the most commonly used treatment technique in the stomatology department, and refers to a process of separating and removing the root of a tooth and an alveolar bone. If the area of the root in contact with the alveolar bone is small, tooth extraction is relatively labor-saving, for example, extraction of a loosened tooth is performed. In most cases, tooth extraction is not so easy, and the greatest difficulty for the patient is to maintain the mouth-opened posture for a long time.

Doctors often place mouth openers in the mouth of a patient in order to keep the patient open. But long-time placing and the volume ratio of current gag are great, hinder medical staff's sight easily, inconvenient observation, and the process of placing simultaneously is loaded down with trivial details, adjusts inconveniently, and the time is one long, often can lead to patient's hydrops can not in time clear up, phenomenon such as the angle of the mouth is torn even.

Detailed Description

To facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, a schematic diagram of a dental forceps according to an embodiment of the present invention is shown, the dental forceps includes two rotatably connected support rods 10, a rotating shaft 20, a forceps portion 30 and a tension spring 40. Wherein, two brace rods 10 which are connected in a rotating way are like a lever and generally play a role in supporting the mouth to be opened, the rotating shaft 20 is a fulcrum of the brace rod 10, the clamp part 30 plays a role in tooth extraction, and the tension spring 40 is used for keeping the opening and closing angle of the brace rod 10. Each of the components will be described separately below.

Regarding the struts 10, two struts 10 are installed like scissors, the struts 10 include a first segment 11 and a second segment 12, the first segment 11 is used for opening the oral cavity, and the second segment 12 is provided with a shaft hole in which the rotating shaft 20 is installed. The first pole segment 11 is elastically connected to the second pole segment 12. Preferably, the first rod section 11 and the second rod section 12 are connected by a spring, and of course, they may be connected by rubber or the like, which is not described herein in too much detail. In addition, stainless steel is preferred for the stay 10 because it extends into the mouth and should avoid rusting. In order to facilitate the grasping of the hands of the medical staff and the application of force, the surface of the second rod section 12 is locally provided with diamond grains 13 to increase the friction of the contact surface. Of course, other patterns may be provided in other embodiments, and the present invention is not limited thereto.

With respect to the jaw portion 30, it is slightly modified from the existing dental forceps. The jaw portion 30 includes a jaw 31 and a jaw handle 32. In order to facilitate the doctor to adjust the angle of the forceps head 31 according to the position of the target tooth, the forceps head 31 is rotatably connected with the forceps handle 32. The clamp handle 32 is provided with a through slot, the rotating shaft 20 passes through the through slot, and the clamp handle 32 is slidable relative to the rotating shaft 20, that is, the clamp handle 32 is slidable relative to the stay bar 10. The dental forceps further includes a stopper 50, the stopper 50 is attached to an end portion of the rotary shaft 20, and an end surface of the stopper 50 abuts against the forceps handle 32. In other embodiments, the stop piece 50 can be spaced from the handle 32, i.e., the shaft 20 is loosely connected to the handle 32, so as to ensure the handle 32 to move freely in multiple dimensions.

As regards the tension spring 40, which is provided between the two second pole segments 12, the tension spring 40 is used to keep the two second pole segments 12 tending to approach each other, always with tension between the second pole segments 12. To avoid interference between the tension spring 40 and the movement of the forceps handle 32, the forceps handle 32 is provided with a bushing 33, and one end of the tension spring 40 is connected with the bushing 33.

The utility model discloses use of embodiment: medical staff enlarges the opening and closing angle of the two second rod sections 12 first to cause the opening and closing angle of the two first rod sections 11 to be reduced, then the first rod sections 11 stretch into the oral cavity, one end of the first rod sections 11 is abutted to the wall part of the oral cavity, the hand part loosens the acting force of the second rod sections 12, and the second rod sections 12 keep the opening angle under the action of the tension spring 40. The posture of the forceps handle 32 is adjusted, 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, this tooth forceps has not only covered the function of extracting teeth, has still included the fixed function of opening one's mouth to the angle of opening one's mouth is adjustable, and the relative position of jaw 30 and vaulting pole 10 is clear simultaneously, does not produce and interferes, has reduced the risk that causes the damage to the patient.
