The utility model discloses simple structure, convenient to use, it is with low costs, more do benefit to opening of unilateral temporomandibular joint, provide the one field of vision open relatively for the operation.
Description
Technical field
This utility model belongs to field of medical auxiliary equipment, relates to a kind of joint dilator, is a kind of Unilateral TMJ surgical dilator specifically.
Background technology
Need to open remporomandibular joint in remporomandibular joint operation, broaden one's vision, facilitate operation technique, gag is used in opening of existing remporomandibular joint, as patent No. oral cavity mouth gag disclosed in the Chinese patent of CN203089444, comprise the elastic opening device body that size, profile and an oral cavity are suitable, described elastic opening device body has two for the occlusion of maxillary and mandibular teeth row, relative inclined-plane, and two inclined-planes are all longitudinally provided with anti-slop serrations; Oral cavity mouth gag also comprises a pull tab device, the both sides of described elastic opening device body are respectively provided with a connecting device, described pull tab device is detachably connected by connecting device described in one of them and described elastic opening device body, not only there is good serviceability, and have the function of pull tab device concurrently, greatly reduce the amount of labour of medical personnel.Gag just described above, these gags existing are all that bilateral remporomandibular joint is opened simultaneously, and clinical operation are mostly one-sided operation on joint, it is larger that resistance is opened in bilateral joint simultaneously, and there is no need also is a kind of waste.Double-side opening mouthpart is different from operative indication of the present invention on the market at present, and double-side opening mouthpart palate pharyngeal operation such as cleft palate, the oropharyngeal tumours of being applied to is performed the operation more, for one-sided operation on joint, and the dilator be not also applicable to.
Utility model content
The purpose of this utility model is to provide a kind of Unilateral TMJ surgical dilator, and structure is simple, and easy to use, cost is low, is more conducive to opening of Unilateral TMJ, for operation provides a relative wide visual field.
In order to achieve the above object, this utility model adopts following technical scheme: a kind of Unilateral TMJ surgical dilator, comprise an elastic rubbery body, described elastic rubbery body comprises lower functional areas and upper functional areas, the surface of described upper functional areas forms function curved surface, the lower surface indent of described lower functional areas forms one time and is engaged groove, and the middle part of described upper function curved surface forms a upper bite corresponding on vertical position with described lower occlusion groove.
This technical scheme safety non-toxic, opening of Unilateral TMJ can be facilitated, occlusion is stable, not easily landing, the one-sided effect opened, from the angle of biomechanics, one-sided opening can obtain larger joint space, for working place is created in operation, the present invention can adapt to one-sided operation on joint better.
As preferably, the ultimate range between the occlusal surface of described lower occlusion groove and the occlusal surface of described upper bite is 10-15mm.Can cut down according to actual needs or increase during operation.
As preferably, the both sides of described lower occlusion groove form edge, left limit side and edge, right limit side respectively, and the width on edge, described left limit side is greater than the width on edge, described right limit side.
As preferably, the thickness of described elastic rubbery body near outside is greater than the thickness of described elastic rubbery body near inner side, and the occlusal surface of described lower occlusion groove and the occlusal surface of described upper bite tilt slightly to the inside.
As preferably, described upper bite is less than the length of described lower occlusion groove in length, and described upper bite is near the rear portion of described lower occlusion groove.
As preferably, described elastic rubbery body is 1-2 ㎝ along the length on dental articulation direction.
As preferably, the occlusal surface of described lower occlusion groove is provided with anti-skidding occlusion stricture of vagina.
As preferably, the occlusal surface of described upper bite is also provided with anti-skidding occlusion stricture of vagina.
By implementing technique scheme, this utility model has following beneficial effect: this utility model structure is simple, and easy to use, cost is low, is more conducive to opening of Unilateral TMJ, provides the visual field that relatively open for performing the operation.
Accompanying drawing explanation
Accompanying drawing 1 is the front view of this utility model one embodiment;
Accompanying drawing 2 is the side view of this utility model one embodiment.
In figure, 1-gum elastic main body; Functional areas under 11-; Groove is engaged under 111-; Edge, 1111-left limit side; Edge, 1112-right limit side; The upper functional areas of 12-; The upper bite of 1211-.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
A kind of Unilateral TMJ surgical dilator, as shown in accompanying drawing 1,2, comprise an elastic rubbery body 1, can according to the smaller difference fine adjustment voluntarily of the size of the tooth form of user or tooth, to coordinate with tooth better, elastic rubbery body 1 is 1-2 ㎝ along the length on dental articulation direction, and general action is on the tooth of about 3, ensure the effect of one-sided expansion, the present embodiment is 1.5cm.The thickness of elastic rubbery body 1 near outside is greater than the thickness near inner side, and said outside, refers to the outside in oral cavity, and inner side refers near intraoral side.Elastic rubbery body 1 comprises and the lower functional areas 11 of lower row's teeth contact and the upper functional areas 12 with upper row's teeth contact, and the lower surface indent of lower functional areas 11 forms one time occlusion groove 111; The surface of upper functional areas 12 forms function curved surface 121, and middle part forms a upper bite 1211 corresponding on vertical position with lower occlusion groove 111; The occlusal surface of lower occlusion groove 111 and the occlusal surface of upper bite 1211 tilt slightly to the inside, are convenient to occlusion.Upper bite 1211 is less than the length of lower occlusion groove 111 in length, and upper bite 1211, near the rear portion of lower occlusion groove 111, after occlusion, opens joint very naturally, and follow-up fixed effect is better, is not easy to slide; Further, lower occlusion groove 111 with the occlusal surface of upper bite 1211 are all provided with anti-skidding occlusion stricture of vagina; Further, the both sides of lower occlusion groove 111 formed respectively left limit side along 1111 and right limit side along 1112, the width of left limit side along 1111 is greater than the width of right limit side along 1112, and follow-up fixed effect is better.Ultimate range between the occlusal surface of lower occlusion groove 111 and the occlusal surface of upper bite 1211 is 10-15mm, and remporomandibular joint can be ensured to expand, and be unlikely to again highly too large, cause pulling of facial muscle, the present embodiment is preferably 12mm.
