Description

Oral surgical forceps

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an oral surgical forceps.

Background

The oral surgical forceps is a tool used for stomatology department and used for taking and transferring auxiliary materials in oral cavity; for taking and stabilizing the soft tissue piece during sewing; for cutting, holding and suturing soft tissues during fine microsurgery operation.

The dentist carries out operation or takes, passes auxiliary material etc. in the oral cavity because the oral cavity is darker and the visual angle is little and more difficult to observe, consequently all need illumination to assist when using usually, and need observe the oral cavity, therefore the doctor again closely observes, just leads to the contradiction between illumination and the field of vision, and sometimes the doctor needs to use the reflector and takes one hand and be inconvenient to hold the magnifying glass and observe, consequently has appeared the tweezers that have the magnifying glass, like the adjustable dental forceps of chinese patent publication No. CN208725918U, though it has the magnifying glass, it is located the clamping end portion of tweezers, can enter the oral cavity, to observing the help less, and its angle and position can not adjust. Therefore, the oral surgical forceps are provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an adjustable observation angle and oral cavity surgical forceps of position to solve the problem that provides among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an oral cavity surgical forceps, includes the main part, the intermediate junction of main part has the dead lever, be provided with the adjusting part that can carry out adjustment position and angle on the dead lever and be connected with the magnifying glass through adjusting part.

Preferably, the adjusting part includes the telescopic link, the end connection of dead lever has the connecting block, the connecting block is articulated with the dead lever, the end fixed connection of connecting block and telescopic link, telescopic link are used for adjusting the position of magnifying glass to can more convenient observation, and articulated then be convenient for adjust the angle of magnifying glass.

Preferably, the lateral wall sliding connection of the output of telescopic link has the installation piece, just the output of telescopic link is seted up flutedly, be provided with the elastic component in the recess, the one end and the magnifying glass fixed connection of telescopic link are kept away from to the installation piece, and the elastic component exerts certain power to the installation piece and makes it keep stable state, and can rotate the installation piece at will to change the angle of autogyration of magnifying glass, so that accomodate and stretch out.

Preferably, the end of the screw at the hinged position of the connecting block and the fixing rod is connected with a rotating block, and the rotating block can rotate the screw more conveniently so as to adjust the tightness of the hinged position.

Preferably, the side wall of the outer ring of the rotating block is provided with anti-slip lines, and the anti-slip lines can increase friction force so as to prevent slipping and require larger force.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a telescopic link and connecting block among the adjusting part carry out the regulation of position and angle to the magnifying glass, but also the installation piece that still can pass through telescopic link end connection rotates the angle of magnifying glass self, and three kinds of regulation cooperations enable the magnifying glass can be in each position and observe to the rotation of installation piece can be convenient for accomodate the magnifying glass between the two centre gripping arms of main part, so that more conveniently accomodate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an oral cavity surgical forceps, includes main part 1, the intermediate junction of main part 1 has dead lever 2, and dead lever 2 is located the centre of two centre gripping arms of main part 1, can be when tweezers use, and two centre gripping arms are drawn close inwards and can not influence the stability of dead lever 2 to the influence is observed, be provided with adjusting part 3 that can carry out adjusting position and angle on dead lever 2 and be connected with magnifying glass 4 through adjusting part 3.

The adjusting part 3 comprises an expansion link 5, the end part of the fixing rod 2 is connected with a connecting block 6, the connecting block 6 is hinged to the fixing rod 2, the connecting block 6 is fixedly connected with the end part of the expansion link 5, the angle between the adjusting part 3 and the main body 1 is changed through the hinged rotation of the connecting block 6 on the fixing rod, and the position of the magnifying lens 4 is changed through the expansion link 5 after the angle is changed.

The outer side wall of the output end of the telescopic rod 5 is connected with a mounting block 7 in a sliding way, the output end of the telescopic rod 5 is provided with a groove 8, an elastic element 9 is arranged in the groove 8, the elastic element 9 mainly applies certain force to the mounting block 7, so that the magnifier can be in a stable state and can not rotate randomly, the elastic piece is made of a material with good elasticity such as a flexible rubber block, or a spring is used, the embodiment adopts the spring, it is more stable and reliable to use, and long-lived, because of having elasticity, therefore the mounting block 7 can rotate on the end of the telescopic link 5, make the symmetrical plane of two convex surfaces of the magnifying glass parallel to the side of the fixed block while taking in, then the angle that the me needs to observe rotates by oneself while using, one end of the mounting block 7 far away from the telescopic rod 5 is fixedly connected with the magnifier 4, the middle parts of the two clamping arms of the main body 1 are provided with a certain convex structure, so that the holding arms do not touch the magnifying glass 4 and the fixed rod 2 when the holding tips of the tweezers are folded.
