Abstract
This utility model discloses a kind of mandible angle retractor, comprises handle and working end, and working end becomes 30-60 to spend angle with handle, described working end is Y type, comprise divergent ends and link, the port of described divergent ends arranges the cheicers to downward-extension respectively, and described link is connected with handle.The utility model has the advantage of, 1. adopt appropriate design, working end is designed to Y-shaped, is deep into lower jaw member lower edge and ramus of mandible trailing edge respectively, exposes surgical field of view widely.2. link is designed to semilune, conforms to bicker profile, ensures maximum contact area, reduces the damage to bicker, can pull open bicker again simultaneously, exposes the surgical field of view in deep.3. because working end area is large compared with traditional drag hook, power drill and soft tissue can be isolated more fully, avoid accidentally injuring, play protection masseter and buccal mucosa.
Description
Technical field
This utility model relates to medical apparatus and instruments, more particularly, relates to the drag hook used in a kind of operation.
Background technology
Surgery tractor is one of apparatus the most frequently used in art, and it is that patient exposes the visual field large as far as possible in otch little as far as possible, and with raising surgical quality, shorten operating time, reducing operation wound has tight association.Different operative sites needs to use different drag hooks, the relation of oromaxillo-facial region because dissecting, operation technique narrow space.During operation for the capable angle of mandible region of intra-oral approach, be not exclusively used in the pull hook of angle of mandible finishing.The defect of other traditional drag hooks is as follows: 1. in order to go deep into angle of mandible, be usually designed to slender type, but fully can not expose surgical field of view (ramus of mandible, angle of mandible, lower jaw member); 2. large to bicker damage, easily tear bicker and cause angular cheilitis, bring misery to patient; 3. less to the obstruct protective effect of masseter, buccal mucosa, usually can damage.
Chinese utility model patent: CN2336754Y discloses a kind of mandible angle retractor, comprises handle, and its structural feature is that the cross section of pull head handle is curved, and pull head is curved surface pull head.Its curved surface pull head can not be deep into lower jaw member lower edge and ramus of mandible trailing edge, and the surgical field of view of exposure is limited.
Summary of the invention
Technical problem to be solved in the utility model is, provides one can be deep into lower jaw member lower edge and ramus of mandible trailing edge respectively, exposes the mandible angle retractor of surgical field of view widely.
In order to solve the problem, this utility model provides a kind of mandible angle retractor, comprise handle and working end, it is characterized in that, described working end becomes 30-60 to spend angle with handle, described working end is Y-shaped, comprises divergent ends and link, the port of described divergent ends arranges the cheicers to downward-extension respectively, and described link is connected with handle.
As a preferred version, described working end and handle are in angle of 45 degrees.Arranging of acute angle can protect buccal soft tissue.
As a preferred version, described link has the radian raised up, and the radian raised up makes link become semilune, conform to bicker profile, ensure maximum contact area, reduce the damage to bicker, can bicker be pulled open again simultaneously, expose the surgical field of view in deep.
As a preferred version, the bifurcation angle of described divergent ends can regulate, to adapt to the patient of different angle of mandible angle.
As a preferred version, the length of described link can regulate.
As a preferred version, described handle arranges handle hole, during operation technique, finger can be hooked in handle hole place and apply active force.
The utility model has the advantage of, 1. adopt appropriate design, working end is designed to Y-shaped, is deep into lower jaw member lower edge and ramus of mandible trailing edge respectively, exposes surgical field of view widely.2. link is designed to semilune, conforms to bicker profile, ensures maximum contact area, reduces the damage to bicker, can pull open bicker again simultaneously, exposes the surgical field of view in deep.3. because working end area is large compared with traditional drag hook, power drill and soft tissue can be isolated more fully, avoid accidentally injuring, play protection masseter and buccal mucosa.
Accompanying drawing explanation
Fig. 1 is this utility model mandible angle retractor structural representation.
Schematic diagram when Fig. 2 is the use of this utility model mandible angle retractor.
Label in diagram is: 1---hands handle; 11---handle hole; 2---working end; 21---link; 22---divergent ends; 23---cheicers.
Detailed description of the invention
Elaborate to this utility model below in conjunction with accompanying drawing, the purposes of embodiment is only to explain the present invention and non-limiting technical scheme.
Embodiment 1.
Refer to Fig. 1, mandible angle retractor comprises handle 1 and working end 2, angle is spent for 1 one-tenth 30-60 with handle in working end 2, preferably 45 degree of angles, described working end 2 is Y-shaped, comprise divergent ends 22 and link 21, the port of divergent ends 22 arranges the cheicers 23 to downward-extension respectively, and link 21 is connected with handle 1.
Continue see Fig. 1, link 21 has the radian raised up, and the radian raised up makes link 21 one-tenth semilune, conform to bicker profile, ensure maximum contact area, reduce the damage to bicker, can bicker be pulled open again simultaneously, expose the surgical field of view in deep.
The bifurcation angle of divergent ends 22 can regulate, to adapt to the patient of different angle of mandible angle.By on a bifurcated wherein, screw and nut can be set, to regulate its bifurcation angle.The length of link 21 can regulate.Link can be designed to the two-part that is nested, regulate its length by swivel nut, or the draw-in groove maintenance by being nested, elongate or shorten its length.
Handle 1 is arranged handle hole 11, during operation technique, finger can be hooked in handle hole place and apply active force.
Refer to Fig. 2, schematic diagram when Fig. 2 is mandible angle retractor use, bone-shaped represents mandibular bone, and crescent shape arc represents bicker.During use, Y shape working end is deep into lower jaw member lower edge and ramus of mandible trailing edge respectively, exposes surgical field of view widely.The radian that link raises up makes link become semilune, conforms to bicker profile, ensures maximum contact area, reduces the damage to bicker, can pull open bicker again simultaneously, exposes the surgical field of view in deep.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
