Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of cheekbone chin subtended angle formula shedding motion.
Background technology
Gag is a kind of auxiliary implement that opens patient's mouth by external force, while being mainly used in operation on oral cavity, opens patient's the upper jaw and the lower jaw.And existing gag is all by stretching into intraoral apparatus, the upper jaw and the lower jaw to be pried open, such operation can cause damage in various degree to patient's tooth, gingiva and oral mucosa on the one hand, on the other hand, because apparatus has occupied intraoral a part of space, also can stop the visual field of operation, the working place of Reduction surgery, reduce the efficiency of operation.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of without apparatus being stretched in patient's oral cavity, just can separate the cheekbone chin subtended angle formula shedding motion of patient's the upper jaw and the lower jaw.
The scheme that solves the technology of the present invention problem is: cheekbone chin subtended angle formula shedding motion, consists of grip tab, handle, rivet, spacing band, side trip bolt, rear trip bolt, post-tensioning contact pin, rotating shaft, axle sleeve, side cover, locating dowel, tooth, tooth bar, front fixed strip, draw ring handle, draw ring, spring, tabletting, tabletting axle sleeve, bit pressing shaft, tabletting pedestal, alignment pin, locating slot and a minute bit strip.
Wherein, spacing band is the flexible structure of plastic material, spacing band originates in the collare nest place of patient head, spacing band is walked around the crown and at place between the eyebrows place, is divided into left and right two stock bit strips downwards, two minutes described bit strips pass through respectively the lower limb of left and right cheekbone, and the lower end of two minutes bit strips lays respectively at the remporomandibular joint place of patient head both sides.There is the grip tab of the rectangular metal material connecting as one by rivet with spacing band the position that is positioned at forehead central authorities at spacing band, is welded with handle in grip tab.
Post-tensioning contact pin is semiorbicular sheet metal, and the mid point of post-tensioning contact pin is positioned at collare nest place, and the mid point of post-tensioning contact pin and the initiating terminal of described spacing band connect as one with rear trip bolt.The two ends of post-tensioning contact pin lay respectively at the remporomandibular joint place of head both sides.The two ends of post-tensioning contact pin have respectively one with the as a whole columnar locating dowel of post-tensioning contact pin, each locating dowel has a side trip bolt that stretches in locating dowel and be spirally connected with locating dowel, and the lower end of each spacing band is fixed between the head of a nail and locating dowel top of corresponding with it side trip bolt.
Junction in each locating dowel and post-tensioning contact pin also has the rotating shaft as a whole with post-tensioning contact pin, and in each rotating shaft, cover has an axle sleeve, and axle sleeve can rotate around the axis.On each axle sleeve, have one with the as a whole side cover of axle sleeve, side cover is hollow strip structure, the end of side cover opens wide.
Front fixed strip is the sheet metal of arc, and one end of the middle part of front fixed strip and shaft-like draw ring handle is welded as a whole, and the other end of draw ring handle is the draw ring as a whole with draw ring handle.There is the tooth bar of the bar shaped as a whole with front fixed strip at the two ends of front fixed strip, have equally distributed tooth on the lateral wall of each tooth bar.The lower limb at the middle part of front fixed strip is positioned at the upper edge of chin knuckle.The end of left and right two tooth bars is inserted left and right side cover and respectively and is become clearance fit relationship with the inwall of left and right side cover from the end opening wide of left and right side cover respectively.
On the lateral wall of each side cover, have with side and overlap as a whole tabletting pedestal, bit pressing shaft and the welding of tabletting pedestal, tabletting axle sleeve is placed in bit pressing shaft and can rotates around bit pressing shaft.On the excircle sidewall of tabletting axle sleeve, have respectively tabletting and the alignment pin of the bar shaped as a whole with tabletting axle sleeve, tabletting and alignment pin are mutually an obtuse angle.In the end of alignment pin, have a right angle turnover, the end of this right angle turnover is through the locating slot putting in side and insert on tooth bar in the gap between two corresponding with it teeth.Between tabletting and side cover, be provided with spring, weld with tabletting and side cover respectively at the two ends of spring.
The side towards skin at post-tensioning contact pin, spacing band, side cover, tooth bar, minute bit strip and front fixed strip is all bonded with one deck foam mat.
During operation, first regulate the total length of side cover and tooth bar so that the top of the inwall of front fixed strip and chin knuckle fits tightly, during adjusting, first with thumb, the end of tabletting is pressed, the now end perk of alignment pin, the right angle turnover of alignment pin end is also extracted out thereupon from locating slot.When the length of the tooth bar in inserting side cover reaches and needs, unclamp thumb, now in the end of the promotion lower sheeting of spring, be upturned, the end of alignment pin moves downward and drives its right angle turnover again through locating slot and be inserted between two corresponding with it teeth.Now, the position relationship of front fixed strip and chin knuckle is fixed.Then left hand is held handle, the right hand is held draw ring the downward application of force, because spacing band and coordinating of cheekbone can stop maxillary to move downward, and front fixed strip can stop lower jaw to move upward with coordinating of chin knuckle, when therefore before draw ring drives, fixed strip moves downward, lower jaw just be take remporomandibular joint and is rotated as axle center under the effect of external force, thereby separates with maxillary.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention can just can separate patient's the upper jaw and the lower jaw in the situation that any member not being stretched into patient oral cavity, this compared with prior art, avoided apparatus to cause damage to the intraoral tooth of patient, gingiva and oral mucosa on the one hand, also avoided on the other hand traditional mouth-gag to stretch into behind oral cavity, because occupying intraoral space stopping operation technique generation, improved the intraoral visual field, for operation technique provides the best visual field and sufficient working place, improve the effect of operation, shortened the time of operation.
2. the separation due to the upper jaw and the lower jaw relies on draw ring handle to drive chin knuckle to rotate around the axis to realize downwards, and the position of rotating shaft is arranged on remporomandibular joint place, therefore, the motion of lower jaw is also to rotate around remporomandibular joint, this is the physiological structure rule that meets head skeleton, therefore the present invention is not only easy to operate, but also under the prerequisite that can not exert an influence in remporomandibular joint, realizes the separation of the upper jaw and the lower jaw.
