Description

Oral retractor adapting to human oral cavity

Technical Field

The utility model belongs to the field of oral surgical tools, and particularly relates to an oral retractor suitable for an oral cavity of a human body.

Background

The oral maxillofacial plastic surgery requires surgery in the oral cavity for the most part due to the requirements of patients and the anatomical features of the oral maxillofacial. While intraoral surgery has intrinsic tissue barriers such as lips, cheeks, etc., the surgery must pull these parts apart to facilitate the procedure.

Based on this, the oral drag hook for oral surgery appears on the market, but current oral drag hook has different length and specification, but because the oral cavity structure of human body is all different, can't accomplish with the oral cavity fit completely, can't accomplish the laminating completely with human oral cavity, the condition of insufficient protection often appears in the intraoperative mucous membrane to the oral mucosa, especially the oral mucosa of angle, leads to postoperative patient's angle of mouth inflammation to aggravate, forms ulcer or scar even, influences patient's postoperative wound healing and to the satisfaction of operation.

Disclosure of Invention

In order to solve the problems, the primary aim of the utility model is to provide an oral retractor which is adapted to the oral cavity of a human body, can be completely adapted and attached to the oral cavity of the human body, and improves the protection effect on the oral cavity;

the utility model also aims to provide the oral retractor which is suitable for the oral cavity of a human body, and has the advantages of simple structure, low cost and convenient use and popularization.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides an oral cavity drag hook which is adapted to the oral cavity of a human body, and the oral cavity drag hook comprises a handle and an oral cavity drag hook which are fixedly connected, wherein a hook groove with an opening front and back is arranged on one surface of the oral cavity drag hook, which is close to the handle, the hook groove is adapted to the shape of the oral cavity of the human body, and the bottom surface of the hook groove is an outwards convex arc surface. Can better adapt to the oral cavity of a human body and avoid the damage to the oral cavity caused by the uncomfortableness of the size of the drag hook.

Further, arc-shaped guard edges are arranged on two sides of the hook groove.

Further, the handle is of an arc rod-shaped structure, and the inner side surface of the handle, which is close to the angle drag hook, is an inward concave arc surface. The inner side surface is set to be an arc surface which is concave, so that a certain distance exists between the handle and the human face when the novel human face massage device is used, the handle can be conveniently held, and the human face can be prevented from being squeezed by the handle.

Further, anti-skid patterns are further arranged on the handle.

Further, the oral retractor is made of photosensitive resin. The material is soft and has excellent heat insulation effect, does not conduct heat while being insulated, and can protect the oral cavity.

Further, the oral cavity drag hook is integrally processed and manufactured by adopting a 3D printing technology. Before operation, three-dimensional CT of the jaw face of a human body is shot, the anatomical structure of the oral cavity of a patient, especially the lip and cheek area, is rebuilt by using related software, and a personalized oral cavity drag hook which is suitable for the oral cavity structure of the patient is manufactured by using a 3D printing technology. On the one hand, due to the high conformability to the oral structure of the patient and taking into account the situation of the open surgery, the patient comfort and compliance are greatly increased; meanwhile, by utilizing three-dimensional CT digital design and computer modeling, the artificial error caused by different manufacturing levels is reduced. When the utility model is used, the angle retractor is fixed at the angle position, the handle is pulled backwards, the operation vision is fully exposed, the clinical requirement is met, and the mucous membrane around the angle is protected while the comfort is improved.

The utility model has the advantages that compared with the prior art:

firstly, the oral cavity drag hook is processed by adopting a 3D printing technology, so that a hook groove and a protective edge which are matched with the shape of a human body oral angle can be formed on the drag hook, the oral cavity drag hook can be more completely matched and attached with an oral cavity, the oral cavity is not pressed, and the oral cavity can be better protected;

and secondly, the utility model has simple structure, low production cost and convenient use and popularization.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

referring to fig. 1, this embodiment provides an oral retractor for adapting to the oral cavity of a human body, which comprises a handle 1 and an oral retractor 2 that are fixedly connected, wherein a hook groove 3 with front and rear openings is arranged on one surface of the oral retractor 2, which is close to the handle 1, the hook groove 3 is adapted to the shape of the oral cavity of the human body, and the bottom surface of the hook groove 3 is an arc surface with a convex shape. Can better adapt to the oral cavity of a human body and avoid the damage to the oral cavity caused by the uncomfortableness of the size of the drag hook.

Further, both sides of the hook groove 3 are provided with arc-shaped guard edges 4.

Further, the handle 1 is of an arc rod-shaped structure, and the inner side surface of the handle 1, which is close to the angle drag hook 2, is an inward concave arc surface. The inner side surface is set to be an arc surface concave, and when the novel human face-care device is used, a certain distance exists between the handle 1 and the human face, so that the handle 1 can be conveniently gripped, and the handle 1 can be prevented from extruding the human face.

Further, the handle 1 is also provided with anti-skid patterns 5.

Further, the oral cavity drag hook is integrally processed and manufactured by adopting a 3D printing technology. Before operation, three-dimensional CT of the jaw face of a human body is shot, the anatomical structure of the oral cavity of a patient, especially the lip and cheek area, is rebuilt by using related software, and a personalized oral cavity drag hook which is suitable for the oral cavity structure of the patient is manufactured by using a 3D printing technology. On the one hand, due to the high conformability to the oral structure of the patient and taking into account the situation of the open surgery, the patient comfort and compliance are greatly increased; meanwhile, by utilizing three-dimensional CT digital design and computer modeling, the artificial error caused by different manufacturing levels is reduced. When the portable hand-operated hook is used, the hand-operated hook 2 is fixed at the position of the angle of the mouth, the handle is pulled backwards, the operation vision is fully exposed, the clinical requirement is met, and the mucous membrane around the angle of the mouth is protected while the comfort is improved.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
