Description

maxillofacial deep surgery retractor

technical field

The utility model relates to the technical field of medical instruments, in particular to a pull hook used for maxillofacial deep surgery.

Background technique

Surgical retractor is one of the commonly used instruments in surgical operations, and it is an important auxiliary means to ensure the surgical field of view, and its role is very important. In maxillofacial surgery, it often involves related operations on the bones and joint structures of the face. Due to aesthetic requirements, facial incisions usually have to be selected in hidden parts, which often cannot be positioned on the surface of the surgical area; in addition, the maxillofacial tissue structure is complex, and the surgical site has a deep layer. Therefore, when traditional surgical retractors are used to pull open the soft tissue and expose the surgical field of view, it is often difficult to expose the deep surgical area. For example, in mandibular surgery via extraoral approach, the incision on the lower edge of the mandible is often used far away from the mandibular ramus and body surgery area. When the retractor is pulled, in order to expose the distant bone, it is often necessary to extend the incision range to reduce the size of the tissue. Tension; excessive stretching during surgery can even cause soft tissue strain. At the same time, the difficulty of exposing the operation area also increases the difficulty of the operation and prolongs the operation time.

At present, the surgical equipment used in maxillofacial surgery is often dominated by traditional small right-angle retractors, intraoral contra-angles, and inward-retraction angle retractors, which lack corresponding instrument support for extraoral deep maxillofacial surgery. The retractor with this structure is unsatisfactory in terms of performance and structural design, the safety performance of the retractor cannot meet the requirements, and the shape and the operator's grip during the operation cannot be harmoniously coordinated. The mandibular bone in the maxillofacial area causes scratches, which brings trauma to the muscle soft tissue and nerve tissue in the human maxillofacial area, resulting in medical accidents.

Utility model content

The purpose of this utility model is to solve the above-mentioned technical problems, and provide a retractor for maxillofacial deep surgery with reasonable design, which can reduce the extra damage to human skin and soft tissue during the exposure process, has a more humanized structure, and is easy to operate and grasp.

In order to solve the above-mentioned technical problems, the utility model adopts a retractor for maxillofacial deep surgery, including a handle, a hook body and a hook head, the hook body is connected with the handle through a connecting rod, and the angle between the hook body and the connecting rod is Obtuse angle, the hook head is connected to the hook body to form an integral structure, and a folded plate structure is arranged between the hook body and the hook head.

Further, in the above technical solution, the hook head extends outward relative to the connecting rod at the other end of the hook body.

Further, in the above technical solution, the hook head is set inwardly with respect to the connecting rod at the other end of the hook body.

Further, in the above technical solution, the front edge of the hook head is provided with a circular arc-shaped rod placement hole, and claws are provided on both sides of the rod placement hole.

Further, in the above technical solution, the edges of the hook body, the hook head, the hole for placing the rod and the claw are all smooth arc-shaped surfaces.

Further, in the above technical solution, the hook head is configured as an outwardly convex curved panel structure.

Further, in the above technical solution, the handle is a bracket structure.

The beneficial effect that has in the utility model:

1) The obtuse angle design is adopted between the handle end and the hook body for holding. Compared with the traditional 90-degree structure, it can effectively avoid soft tissue damage caused by excessive traction during the operation under the premise of fully exposing the operation field. ;

2) The multi-angle design is adopted between the connecting parts of the entire retractor, so that the operator can hold the retractor more flexibly, facilitate the multi-directional operation of the assistant during the operation, and avoid blocking the view of the surgeon during the operation;

3) Different angles are used between the handle end and the hook head for holding, and the anti-angle or inner angle design is adopted between the hook body and the claw. , so that it can be used not only for fixed stretching of soft tissue, but also for blocking operation of deep soft tissue, and the application is more flexible;

4) The retractor is equipped with a rod-setting hole that is compatible with the retractor used in the operation, which can avoid structural obstruction between different surgical instruments during the operation and facilitate the operation of the operation.

detailed description

Below in conjunction with accompanying drawing, the utility model concrete structure, characteristic and using method thereof are described in detail as follows.

Embodiment one:

As shown in Figure 1, it is a retractor for deep maxillofacial surgery, including a handle 1, a hook body 3 and a hook head 4, the hook body 3 is connected to the handle 1 through a connecting rod 2, and the clip between the hook body 3 and the connecting rod 2 The angle is an obtuse angle, and the hook head 4 is connected to the hook body 3 to form an integral structure, and a folded plate structure is arranged between the hook body 3 and the hook head 4; 2 extend outward. The retractor with this structure is applicable to the blocking operation of deep soft tissues.

Embodiment two:

As shown in Figure 2, it is a retractor for deep maxillofacial surgery, including a handle 1, a hook body 3 and a hook head 4, the hook body 3 is connected to the handle 1 through a connecting rod 2, and the clip between the hook body 3 and the connecting rod 2 The angle is an obtuse angle, and the hook head 4 is connected to the hook body 3 to form an integral structure, and a folded plate structure is arranged between the hook body 3 and the hook head 4; Inner turning settings. The retractor with this structure is suitable for fixed pulling operation on soft tissue.

The obtuse angle design is adopted between the handle end and the hook body for holding in the above retractor structure. Compared with the traditional 90° structure, it can effectively avoid excessive pulling or gridlock during the operation under the premise of fully exposing the operation field.
