The angle of tweezers end can't be adjusted to tweezers that present department of stomatology used when using to lead to the unable nimble somewhere tissue of getting in the oral cavity of pressing from both sides of user, the end of tweezers is receiving the striking to take place the deformation of certain degree easily simultaneously, thereby leads to whole tweezers to scrap, can't carry out the reuse.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a pair of forceps for stomatology department.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a pair of oral forceps comprises two groups of forceps plates which can be opened and closed, wherein one end of each forceps plate is provided with an elbow, and one end of each elbow is provided with a clamping piece for clamping oral tissues;

the welding of the position department on clamping piece surface near one end has the threaded rod, and in the through-hole that the elbow surface was predetermine was worn to establish to the threaded rod to the one end that the threaded rod extends to the through-hole outside is equipped with the cap body.

Preferably, tooth sockets with tooth-shaped sections are formed in the inner sides of the clamping pieces, and the tooth sockets on the surfaces of the two groups of clamping pieces are meshed with each other.

Preferably, a plurality of grooves are uniformly formed in the periphery of the through hole on the surface of the elbow, and the lug is clamped with any one of the grooves.

Preferably, the lug is of a hemispherical structure, and the magnetic absorption layer is electroplated on the surface of the clamping piece at a position corresponding to the elbow.

Preferably, the cross-section of the cap body is T-shaped, the cap body is of a hollow stainless steel structure, and one end of the threaded rod is not in contact with the inner wall of the cap body all the time.

Preferably, the cross section of the through hole is rectangular, and the inner wall of the through hole is straight and smooth.

Compared with the prior art, the utility model provides a department of stomatology tweezers has following beneficial effect:

firstly, set up rotatable clamping piece in the one end of elbow, can adjust the angle of clamping piece according to the position of organizing in the oral cavity, improved the flexibility that whole tweezers used.

Secondly, the tooth socket is arranged on the inner side of the clamping piece, so that the contact surface between the clamping piece and the oral tissue is increased, and the oral tissue can be smoothly clamped to the outside.

And thirdly, the mutually matched convex blocks and the grooves are adopted, so that the position stability of the clamping piece after the angle adjustment can be ensured, the convex blocks can be clamped into the corresponding grooves, and the phenomenon that the clamping piece deflects once more can be completely avoided after the clamping piece is matched with the cap body for use.

Detailed Description

The following describes a specific embodiment of the forceps for stomatology department with reference to fig. 1. The utility model of the forceps for stomatology is not limited to the description of the following embodiments.

In this embodiment, a specific structure of a pair of oral forceps is shown in fig. 1-4, the pair of oral forceps includes two sets of forceps plates 1 that can be opened and closed, an elbow 2 is disposed at one end of each forceps plate 1, and a clamping piece 3 for clamping oral tissue is disposed at one end of each elbow 2;

the surface of the clamping piece 3 is welded with a threaded rod 5 at a position close to one end, the threaded rod 5 penetrates through a through hole 6 which is preset in the surface of the elbow 2, and a cap body 4 is assembled at one end of the threaded rod 5 extending to the outside of the through hole 6.

The rotatable clamping piece 3 is arranged at one end of the elbow 2, so that the angle of the clamping piece 3 can be adjusted according to the position of tissues in the oral cavity, and the use flexibility of the whole tweezers is improved.

Specifically, the type of tweezers exists the end that has curved shape in current department of stomatology, conveniently presss from both sides the somewhere tissue of getting oral cavity depths, and this type of tweezers if take place to drop or when striking when using, very easily cause the end to take place the phenomenon of bending once more to cause whole tweezers to can't use, and use the utility model discloses a during tweezers, if take place the crooked phenomenon of clamping piece 3, can directly dismantle the change with this partial clamping piece 3, thereby the cost is reduced to a certain extent.

As shown in fig. 3, tooth grooves 31 with tooth-shaped cross sections are formed on the inner sides of the clip pieces 3, and the tooth grooves 31 on the surfaces of the two sets of clip pieces 3 are engaged with each other.

The tooth grooves 31 are formed in the inner sides of the clamping pieces 3, so that the contact surfaces of the clamping pieces 3 and oral tissues are increased, and the oral tissues can be smoothly clamped to the outside.

As shown in fig. 3 and 4, the outer side of the clamping piece 3 is welded with a convex block 8 at a position adjacent to the threaded rod 5, a plurality of grooves 9 are uniformly formed on the surface of the elbow 2 around the through hole 6, and the convex block 8 is mutually clamped with any one of the grooves 9.

As shown in fig. 3, the bump 8 is a hemispherical structure, and the magnetic absorption layer 7 is electroplated on the surface of the clip 3 corresponding to the bend 2.

Above-mentioned adopt mutual supporting lug 8 and recess 9, can guarantee that clamping piece 3 carries out the position stability after the angle modulation, in lug 8 can block to a recess 9 that corresponds, cooperation cap 4 uses the back, can avoid clamping piece 3 to take place the phenomenon of deflecting once more completely.

As shown in fig. 2 and 3, the cross-section of the cap body 4 is "T" shaped, the cap body 4 is a hollow stainless steel structure, and one end of the threaded rod 5 is not in contact with the inner wall of the cap body 4 all the time.

As shown in fig. 3 and 4, the cross section of the through-hole 6 is rectangular, and the inner wall of the through-hole 6 is straight and smooth.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
