Abstract

The utility model relates to an oral-maxillofacial surgery retractor that is is characterized in that the retractor contains a handle and retractor heads arranged at the both ends of the handle. The front end of the U-shaped retractor head varies in the length. The utility model has the advantages of a simple structure, a small size and corrosion resistance. In the operations on the mandibula ascending branch or the maxillary bone, according to the positions of the operative sites of patients, different retractors can be chosen to operate, which makes the operation stable and easy, and the operative field exposure sufficient.

Description

The Oral and Maxillofacial Surgery surgery tractor

(1), affiliated technical field

This utility model relates to a kind of operating theater instruments, particularly a kind of drag hook of Oral and Maxillofacial Surgery operation.

(2), technical background

In the Oral and Maxillofacial Surgery clinical position, often need carry out the operation at mandibular bone ascending branch and upper jaw bone position, the oromaxillo-facial region complex structure, approach will be avoided important nerve, vitals etc., also to consider the factor that patient's postoperative is attractive in appearance, therefore, operative incision generally is selected in the mouth or at comparatively hidden jaw inferior segment, when particularly carrying out the operation of faces such as mandibular bone ascending branch position and upper jaw bone middle part, operative site is darker, and is far away with the position of operative incision, the operative incision limited length, the wild exposure of art is insufficient, and this has just brought very big inconvenience for operation technique.And traditional surgery tractor is primarily aimed at the use design of general surgery, and its limitation is arranged.

(3), summary of the invention

The purpose of this utility model just provide a kind of simple in structure, volume is little, corrosion resistant Oral and Maxillofacial Surgery surgery tractor.It can draw back the soft tissues such as muscle of superficial surface in the operation of carrying out mandibular bone ascending branch and upper jaw bone position, fully exposes the art open country.

The purpose of this utility model is to realize by such technical scheme, and it includes handle and is arranged on the drag hook head at handle two ends, and described drag hook head is the U type of front end varying length.

This utility model is to use like this: when undergoing surgery operation, grasp handle, the drag hook head is placed mandibular bone ascending branch or the upper jaw bone surface that needs exposure, the soft tissues such as muscle of superficial surface are drawn back, grow owing to the drag hook head is narrow, further enlarged the space of operation technique.The head of drag hook is the U type, can handle the situation of the tissue surface of being drawn back by the space of U type.

Owing to adopted technique scheme, the utlity model has simple in structure, volume is little, corrosion resistant advantage, it can be in the operation of carrying out mandibular bone ascending branch and upper jaw bone position, situation according to position, corrective surgery position, at any time select different drag hooks to operate, make operation technique stable, convenient, art is wild to be exposed fully.

(5), the specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, a kind of Oral and Maxillofacial Surgery surgery tractor is characterized in that: include handle 1 and the drag hook head 2 that is arranged on the handle two ends, described drag hook head 2 is the U type of front end varying length.

As shown in Figure 2, described drag hook integral body is Z-shaped.When undergoing surgery operation, the other end of drag hook just is upturned, and can not cause obstacle to operation technique.

Shown in Fig. 3,4, the section of described drag hook is curved.In the operation use, arcual concave upright, further enlarged the space of operation technique.
