Description

Technical Field

[0001] The utility model relates to the technical field of extraction forceps, in particular to a structure of an extraction forceps. Background Art

[0002] Tooth extraction is one of the most basic operations in dental treatment. Among them, extraction forceps are most commonly used in dental operations. Extraction forceps are instruments used to hold the tooth crown or root and loosen and dislocate the tooth through actions such as wedging, rocking, twisting, and traction.

[0003] Currently, all extraction forceps are used for tooth extraction through the forceps head. However, due to the hardness of the teeth, the forceps head will be damaged after long-term use, which is not convenient to replace. It is necessary to replace the entire extraction forceps to ensure the tooth extraction effect, increasing the use cost of the extraction forceps. Therefore, we propose a structure of an extraction forceps. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structure of an extraction forceps to solve the problem that currently all extraction forceps are used for tooth extraction through the forceps head, and when replacing the forceps head, the entire extraction forceps need to be replaced, increasing the use cost as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A structure of an extraction forceps, including a first handle, a second handle, a forceps head, and a connection mechanism. The first handle and the second handle are rotatably connected. The forceps head is connected to the front ends of the first handle and the second handle through the connection mechanism. The connection mechanism includes a connection groove, a contraction cavity, a pull rod, a connecting plate, a return spring, a clamping block, a connecting block, and a clamping groove. A connection groove is opened in the middle of the front sides of the first handle and the second handle. A contraction cavity is opened in the middle of the mutually remote sides of the left and right connection grooves. The middle of the mutually remote sides of the left and right contraction cavities is penetrated and slidably connected with a pull rod. The opposite ends of the pull rod are fixedly connected with a connecting plate. The middle of the mutually remote sides of the left and right connecting plates is fixedly connected with a return spring. The middle of the rear side of the forceps head is fixedly connected with a connecting block. A clamping groove is opened in the middle of the mutually remote sides of the left and right connecting blocks.

[0006] As a further description of the above technical solution:

[0007] The connecting plate is slidably connected to the inside of the contraction cavity, and the outer side wall of the connecting plate is attached to the inner side wall of the contraction cavity.

[0008] As a further description of the above technical solution:

[0009] The left end of the left return spring is fixedly connected to the left side of the left contraction cavity, the right end of the right return spring is fixedly connected to the right side of the right contraction cavity, and the return spring is sleeved on the outside of the pull rod.

[0010] As a further description of the above technical solution:

[0011] A bevel is provided on the front side of the clamping block.

[0012] As a further description of the above technical solution:

[0013] An anti - detachment mechanism is fixedly connected to the outer sides of the first handle and the second handle. The anti - detachment mechanism includes a mounting frame, a fixing rod, a circular plate, a tension spring, a fixing seat, a strap and fixing holes. Mounting frames are fixedly connected to the rear parts of the mutually - remote sides of the first handle and the second handle. The middle parts of the mutually - remote sides of the left - and - right mounting frames are slidably connected through the fixing rods. Circular plates are fixedly connected to the mutually - remote ends of the left - and - right fixing rods. A tension spring is sleeved on the outer side of the fixing rod. Fixing seats are fixedly connected to the front parts of the mutually - remote sides of the first handle and the second handle. Straps are fixedly connected to the mutually - remote sides of the left - and - right fixing seats. Fixing holes are uniformly formed through the left side of the strap.

[0014] As a further description of the above technical solution:

[0015] The two ends of the tension spring are respectively fixedly connected to the opposite sides of the circular plate and the mounting frame.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. For the structure of this tooth extraction forceps, during replacement, directly pull the pull rod to move the clamping block out of the card slot, then pull the forceps head to disassemble the forceps head. After that, install a new one, make the connecting block embedded in the connecting slot, squeeze the clamping block, so that the clamping block contracts into the contraction cavity, and the return spring is compressed. When the clamping block is aligned with the card slot, through the reset of the return spring, the clamping block is embedded in the card slot to complete the installation. Thus, the forceps head is modularized, which is convenient for individual replacement, avoids replacing the whole tooth extraction forceps, saves costs, and improves the practicability of the device.
