Description

Technical Field

[0001] The utility model relates to the technical field of extraction forceps for stomatology, in particular to a special extraction forceps for stomatologists in the stomatology department. Background Technique

[0002] When a stomatologist treats a patient's oral teeth, the doctor will use extraction forceps to pull out the damaged teeth of the patient. The extraction forceps are instruments used to hold the tooth crown or root and loosen and dislocate the teeth through actions such as wedging, rocking, twisting, and traction.

[0003] At present, for the existing extraction forceps used by stomatologists, most of the jaws cannot open automatically during use and still need to be manually opened, resulting in poor convenience in using the extraction forceps. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a special extraction forceps for stomatologists, which can make the jaws open automatically without manual opening, improving the convenience of using the extraction forceps.

[0005] Technical Solution

[0006] To achieve the above object, the utility model provides the following technical solution: A special extraction forceps for stomatologists includes a left forceps, a right forceps, and a pin shaft. The left forceps and the right forceps are rotatably installed together through the pin shaft. It also includes an elastic opening mechanism. The elastic opening mechanism includes two groups of connecting blocks and a connecting shaft. The two groups of connecting blocks are symmetrically and fixedly installed on the inner sides of the left forceps and the right forceps respectively. A spring is fixedly connected between the two groups of connecting blocks. At the middle of the front ends of the two groups of connecting blocks, hinge seats are fixedly provided respectively. A left connecting strip and a right connecting strip are respectively hinged on the two hinge seats. An articulated groove is provided at the rear end of the left connecting strip, and a hinge head is provided at the rear end of the right connecting strip. The rear ends of the left connecting strip and the right connecting strip are rotatably connected together through a connecting shaft. The hinge head is inserted into the articulated groove, and limiting platforms are fixedly provided at both the upper and lower ends of the connecting shaft.

[0007] Preferably, anti-slip handle sleeves are sleeved on the front ends of the left forceps and the right forceps.

[0008] Preferably, a plurality of anti-slip protrusions are fixedly provided at equal intervals on the outer side walls of the anti-slip handle sleeves and the anti-slip protrusions.

[0009] Preferably, anti-slip patterns are provided on the jaw planes of the left forceps and the right forceps.

[0010] Preferably, a collar is sleeved between the two anti-slip handle sleeves.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When in use, medical staff hold the left pliers and the right pliers by hand, and by squeezing the left pliers and the right pliers inward to rotate, the jaws are closed and the spring is compressed. When opening, the hand can be slowly opened, and the left pliers and the right pliers rotate outward under the action of the spring rebound, so that the jaws are opened. The degree of opening of the jaws is controlled by the degree of opening of the hand. Through the hinge connection of the left connecting strip and the right connecting strip, it is possible to prevent the jaws from opening too large, so that the jaws can open by themselves without manual opening, improving the convenience of using the extraction forceps.

Detailed Description of the Embodiment

[0020] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0021] Embodiment

[0022] Please refer to Figures 1 - 7, A special extraction forceps for dentists of the present utility model includes a left forceps 1, a right forceps 2 and a pin shaft 3. The left forceps 1 and the right forceps 2 are rotatably installed together through the pin shaft 3. Two groups of connecting blocks 4 are symmetrically and fixedly installed on the inner sides of the left forceps 1 and the right forceps 2 respectively. A spring 5 is fixedly connected between the two groups of connecting blocks 4. In the middle of the front ends of the two groups of connecting blocks 4, hinge seats 6 are fixedly provided respectively. A left connecting strip 7 and a right connecting strip 8 are respectively hinged on the two groups of hinge seats 6. An articulated groove is provided at the rear end of the left connecting strip 7, and an articulated head is provided at the rear end of the right connecting strip 8. The rear ends of the left connecting strip 7 and the right connecting strip 8 are rotatably connected together through a connecting shaft 9. The articulated head is inserted into the articulated groove, and limiting platforms 10 are fixedly provided at both the upper and lower ends of the connecting shaft 9. When in use, medical staff hold the left forceps 1 and the right forceps 2 by hand, and by squeezing the left forceps 1 and the right forceps 2 inward to rotate, the jaws are closed, and the spring 5 is compressed. When opening, the hand can be slowly opened, and the left forceps 1 and the right forceps 2 rotate outward under the action of the spring 5 rebounding, so as to open the jaws. The degree of opening of the jaws is controlled by the degree of opening of the hand. Through the articulation of the left connecting strip 7 and the right connecting strip 8, it is possible to prevent the jaws from opening too large, so that the jaws can open by themselves without manual opening, improving the convenience of using the extraction forceps.

[0023] Anti-slip grips 11 are sleeved on the front ends of both the left forceps 1 and the right forceps 2; by providing the anti-slip grips 11, it is possible to prevent the situation of slipping when the left forceps 1 and the right forceps 2 are held by hand.

[0024] A plurality of groups of anti-slip protrusions 12 are fixedly provided at equal intervals on the outer side walls of the anti-slip grips 11 and the anti-slip protrusions 12; by providing the anti-slip protrusions 12, when the left forceps 1 and the right forceps 2 are held by hand, it is possible to further prevent slipping between the hand and the anti-slip grips 11.

[0025] Anti-slip patterns 13 are provided on the jaw planes of both the left forceps 1 and the right forceps 2; by providing the anti-slip patterns 13, it is possible to increase the friction at the jaw planes and avoid slipping during tooth extraction.

[0026] A collar 14 is sleeved between the two groups of anti-slip grips 11; by providing the collar 14, when not in use, the collar 14 can be sleeved on the two groups of anti-slip grips 11 to keep the spring 5 in a compressed state, so as to prevent the jaws from opening.

[0027] A special tooth extraction forceps for stomatologists of the present utility model, its working principle is as follows. When in use, medical staff hold the left forceps 1 and the right forceps 2 by hand, and by squeezing the left forceps 1 and the right forceps 2 inward to rotate, the jaws are closed, and the spring 5 is compressed. When opening, the hand can be slowly opened, and the left forceps 1 and the right forceps 2 rotate outward under the action of the spring 5 rebounding, so as to open the jaws. The degree of opening of the jaws is controlled by the degree of opening of the hand. Through the hinge of the left connecting strip 7 and the right connecting strip 8, the jaws can be prevented from opening too large, so that the jaws can open by themselves during use. When not in use, after closing the jaws, then put the collar 14 on the two groups of anti-slip grips 11 to keep the jaws closed.
