Abstract

The utility model discloses a maxillary sinus external lifting surgery retractor, including the handle, the bottom of handle is equipped with the bone face fixer, and the one end that the handle was kept away from to the bone face fixer is equipped with the fluke, and handle and bone face fixer, bone face fixer and fluke are fixed connection. The utility model discloses the maxillary sinus promotes operation drag hook outward can the maxillary outside bone wall internal rotation back, utilizes the bone wall fixed, and the soft tissue of upwards tractive oral mucosa can expose the operation completely wild, and bone grafting and planting body implantation under the direct vision improve the accuracy of operation treatment and obtain and stabilize treatment.

Description

Maxillary sinus external lifting operation retractor

Technical Field

The utility model belongs to the technical field of the oral cavity is clinical, concretely relates to maxillary sinus promotes surgery retractor outward.

Background

The oral dental implant technology is widely applied, but for partial maxillary posterior alveolar bone quantity insufficiency, the dental implant operation can be completed only after the maxillary sinus is lifted outwards. The external maxillary sinus lifting operation has small visual field, unclear exposure and serious influence on the completion of the operation and the treatment effect. If the maxillary sinus is lifted, the bone grafting and the implant implantation are completed under a clear visual field, which is the clinical problem to be solved at present.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a maxillary sinus promotes surgery drag hook outward has solved the maxillary sinus that exists among the prior art and has promoted the surgery field of vision outward and expose unclear clinical problem.

The utility model adopts the technical proposal that the utility model relates to an operation drag hook for maxillary sinus external lifting, which comprises a handle, the bottom of the handle is provided with a bone surface fixer, and one end of the bone surface fixer away from the handle is provided with an anchor hook.

The utility model is also characterized in that,

the bone surface fixer and the anchor hook are connected by a narrow bridge, and the narrow bridge is of an arc hook-shaped structure.

The handle is S-shaped.

The bone surface fixer is an arc flat structure, and the radian of the bone surface fixer is consistent with that of the outer side surface of the maxilla of a human body.

The anchor hook is of an arc-shaped structure, the tip end of the anchor hook is in a round blunt shape, and the thickness of the tip end is 3 mm.

The handle, the bone surface fixer and the anchor hook are of an integrated structure formed by pouring.

The utility model has the advantages that: the maxillary sinus external lifting is used as a common surgical technique for maxillary posterior tooth bone deficiency, has small operation visual field and unclear exposure after bleeding, and seriously influences the operation effect of completing bone transplantation and implant implantation under direct vision. The utility model discloses maxillary sinus promotes operation drag hook outward can treat the internal backspin of maxillary outside bone wall, utilizes the bone wall fixed, and the soft tissue of tractive oral mucosa that makes progress can expose the operation completely wild, and bone grafting and planting body implantation under the direct vision improve the accuracy of operation treatment and obtain and stabilize treatment.

fig. 2 is a side view of the maxillary sinus external lifting surgical retractor of the utility model.

In the figure, 1 is a handle, 2 is a bone surface fixer, and 3 is an anchor hook.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, for the utility model relates to a structure diagram of a maxillary sinus external lifting surgery retractor, which comprises a handle 1, the bottom of the handle 1 is provided with a bone surface fixer 2, and one end of the bone surface fixer 2 far away from the handle 1 is provided with an anchor hook 3.

The handle 1 is an arc flat structure, and when the handle 1 is used, the handle can be held by hands to bypass the soft tissue of the upper lip to perform operation.

The bone surface fixator 2 is of an arc-shaped flat structure, the radian of the bone surface fixator is consistent with that of the outer side surface of the maxilla of a human body, and the bone surface fixator 2 can be attached to the bone surface of the front outer wall of the maxilla.

The anchor hook 3 is of an arc-shaped structure, the arc-shaped level is downward, the tip end of the anchor hook 3 is of a round blunt shape, the thickness of the anchor hook is 3mm, the anchor hook 3 has two functions, one function is to fix the anchor hook 3 on the bone surface of a patient to realize fixation, and the problem that the handle 1 needs to be pulled all the time in the operation process of an operation is solved.

The handle 1 and the bone surface fixer 2 are integrally in an inverted 3 shape.

Handle 1 and bone face fixer 2, bone face fixer 2 and fluke 3 both can be for pouring fashioned integrated structure, can also be handle 1 and the integration of bone face fixer 2 and pour and form, connect through the narrow bridge between bone face fixer 2 and the fluke 3, and the narrow bridge between bone face fixer 2 and the fluke 3 is curved hook-like, hooks or fixes the inboard that promotes the osteotomy outside the maxillary sinus downwards, fixed and expose the operation field.

The utility model discloses a use does: after the maxillary bone surface is cut by a maxillary sinus lifting operation, the maxillary sinus mucosa is separated, and the upper and lower bone surfaces of the maxillary side wall fenestration are exposed. Hand-held handle 1, with anchor hook 3 at the upper bone wall of maxillary lateral wall fenestration, can also gently collude upward together free maxillary sinus mucosa, press bone face fixer 2 at the maxillary outside bone face, it is unusual to confirm around, maxillary sinus chamber field of vision is clear, that is 1 fixed that the assistant is handheld, can begin the implantation of planting, at this moment the operation doctor can clearly look at the degree of depth that the planting body implanted maxillary sinus clearly and surely protect the maxillary sinus mucosa, according to the scheme of confirming before the art, it can to implant the planting body in proper order.

The utility model relates to a maxillary sinus promotes surgery retractor outward, simple structure, the equipment that can effectively simplify the operation is operated to the good operation to realize that the operation is simplified more and accurate.
