Abstract

The utility model relates to a medical instrument, in particular to a gingival flap distractor for implant surgery and alveolar ridge plasty. The gingival flap distractor comprises a U-shaped inflexed part (1), a clamping buckle I (2), a clamping buckle II (5), a bitewing I (3) and a bitewing II (4), and is characterized in that the U-shaped inflexed part (1), the clamping buckle I (2), the clamping buckle II (5), the bitewing I (3) and the bitewing II (4) are formed in one step. The gingival flap distractor with a simple structure is convenient to use and can fully distract a gingival flap to expose a surgical area during the implant surgery and the alveolar ridge plasty, thereby facilitating the surgical operation and effectively avoiding gingival wounds.

Description

The gingival flap dilator

Technical field

This utility model relates to a kind of medical apparatus and instruments, more specifically to a kind of gingival flap dilator, is used for implant operation and alveolar ridge Trimming.

Background technology

The tooth-planting technology is a new clinical oral technology that grows up mid-term in 20th century.At present, tooth-planting operation is mainly turned over the lobe planting technology as main take gingiva, namely needs dentium sculptura peeled off when operation to turn over lobe and need bone grafting or complementary procedure special case with abundant exposure alveolar bone, particularly bone quantity not sufficient etc.Because gingiva contains abundant collagen fiber, and is tough and tensile and flexible, the gingival flap of therefore peeling off has the trend on self-resetting alveolar bone surface, has a strong impact on doctor's surgical field of view and operation technique, and causes easily the gingiva damage.Although can push gingiva open with drag hook or periosteal elevator by the assistant when operation technique, oral cavity volume itself is just little, and being made in has like this increased many apparatuses in the oral cavity, can make operation technique very inconvenient.

Summary of the invention:

The technical problems to be solved in the utility model is: solve the problem that gingival flap hinders operation technique in the tooth-planting operation, a kind of simply and easily gingival flap dilator is provided, be used for strutting gingival flap in the operation, make things convenient for operation technique.

This utility model comprises U-shaped revers turn part, buckle I, buckle II, fin I and fin II, and its characteristics are: U-shaped revers turn part, buckle I, buckle II, fin I and fin II, once-forming.

This utility model is simple in structure, easy to use, gingival flap fully can be strutted in implantation body's implantation and alveolar ridge finishing operation, exposes the art district, makes things convenient for operation technique, can effectively avoid the gingiva wound.

Description of drawings

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is this utility model gingival flap dilator structural representation;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the enlarged drawing at A place among Fig. 1;

Fig. 4 is the expanded view of Fig. 1.

The specific embodiment

In Fig. 1,2,3,4: U-shaped revers turn part 1, buckle I 2, buckle II 5, fin I 3 and fin II 4, once-forming adopts Ultimum Ti.Fin I 3 and fin II 4 are cutter shape projection, and its effect is: jut gos deep between gingiva and the alveolar ridge, and firm effect is played in constraint mutually.Insertion gingiva otch after the fin I 3 that opens and fin II 4 closed up, Nitinol be because the memory function of self has the trend of recovering original form, and then produce resilience force, utilizes simultaneously resilience force that gingival flap is strutted, so that operation technique.Buckle I 2 projections and the engagement of buckle II 5 recesses, buckle I 2 recesses and buckle II 5 card convexs go out the part engagement, its effect is: utilize the engagement of buckle I 2 and buckle II 5, the size that the distraction angle of control fin I 3 and fin II 4 struts with the control gingival flap.

This utility model is like this work:

When the surgical incision gingiva and peel off turn over lobe after, clutch fin I 3 and fin II 4 so that fin I 3 and fin II 4 close up, be that buckle I 2 and buckle II 5 block rear insertion gingiva otch mutually, fin I 3 and fin II 4 produce resilience force because of the memory function of Nitinol itself, thereby gingival flap is strutted, utilize buckle I 2 and buckle II 5 engagement what, the size that control fin I 3 and fin II 4 strut gingival flap, thereby expose the alveolus surface of bone, so that operation technique.It is complete to perform the operation, and again clutches fin I 3 and fin II 4, takes out from the gingiva incision after fin I 3 and fin II 4 are closed up.

In sum: this utility model is simple in structure, and is easy to use, can fully expose the art district, makes things convenient for operation technique, effectively avoids the gingiva wound, and the both hands that simultaneously can liberate the doctor make operation efficiently, finish smoothly.
