Abstract
The utility model relates to a puncture sleeve for jaw bone fracture fixing and belongs to the technical field of medical equipment. The puncture sleeve for jaw bone fracture fixing can simultaneously fix the bone surface and a titanium plate, comprises a sleeve body and a straight rod and is characterized in that the sleeve body and the straight rod are in T-shaped fixed connection, the end of the sleeve body not connected with the straight rod is a furcated sleeve head, a press rod is arranged on the furcated sleeve head, and a water filling hole connected with the sleeve body is arranged on the half side of the straight rod. During use, a drill point used during drilling and the sleeve cannot slide easily, a drill hole can be sought easily and screwed with a screw, and the titanium plate can be prevented form moving.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically relates to a kind of jaw fracture and fixedly uses puncture casing.
Background technology
Jaw fracture is a kind of frequently-occurring disease, in the operation of processing jaw fracture, adopts in open reduction, the titanium plate fixing more.Jaw fracture is fixing to be for the fixing fixation aid of jaw fracture in cheek punctures of path open reduction in the per os with puncture casing.Smoothly both without the surface of bone fixation, fixedly the titanium plate easily slides during location drilling existing cannula end, is difficult for finding boring when screwing in screw.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of jaw fracture the fixing puncture casing of using, this sleeve pipe can be simultaneously fixedly surface of bone and titanium plate.
The technical scheme of this utility model technical solution problem is: puncture casing comprises sleeve pipe body and straight-bar, and its main points are, the sleeve pipe body is that T-shaped is fixedly connected with straight-bar, and the end that the sleeve pipe body is not connected with straight-bar is the fork-shaped tube head; Be provided with depression bar at the fork-shaped tube head; One side of something at straight-bar is provided with water injection hole, and water injection hole is communicated with the sleeve pipe body.
The said fork-shaped tube head of this utility model puncture casing is the V-arrangement prong.
Using method of the present utility model is: after choosing puncture position, in fork-shaped sleeve pipe front end drives in the wrong direction the insertion sleeve pipe V-type groove of inner core cone point is connected with the tight joint close of the fork configuration of sleeve pipe puncture inner core tail end, it is for subsequent use that tail end connects the puncture handle.Puncture and successfully press from both sides steady sleeve pipe by otch in the mouth with clamper, the puncture handle that then comes loose is along extracting the puncture inner core in the puncture direction per os.Puncture casing is stayed in the soft tissue of buccal, with drill bit in sleeve pipe outer end threading and the titanium plate hole that is fit to, adjust the clamper tong arm and move sleeve pipe and hole and sleeve pipe fork-shaped terminal spine is entered surface of bone to correct position and pushes down the titanium plate, oppositely withdraw from drill bit and connect screw with bottle opener and stretch in the sleeve pipe and screw in.Observation window between depression bar and fork-shaped tube head intrados can be observed the screw screw-in depth.
The beneficial effects of the utility model are:
1, this utility model puncture casing is owing to be provided with the fork-shaped tube head, and prong fixedly surface of bone, depression bar can be pushed down the titanium plate.Therefore, use present technique drill point and the difficult slip of sleeve pipe when boring, seek easily boring and screw-in screw, and can avoid the titanium plate to move.
2, this utility model puncture casing is owing to be provided with water injection hole, and therefore, simultaneously water filling is cooled off during boring.
3, this puncture casing can not only can also be used in the zygoma complex fracture fixing for the fracture at Mandibular Rumas angle of mandible position
This utility model cost of manufacture is low, and is simple to operate, easy to use, is easy to promote.
Description of drawings
Fig. 1 is the sketch map of the structure of this utility model embodiment.
Fig. 2 is the dextrad structural representation of Fig. 1.
Among the figure: 1, sleeve pipe body, 2, straight-bar, 3, the fork-shaped tube head, 4, water injection hole, 5, depression bar, 6, observation window, 7, the V-arrangement prong.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further details.
See figures.1.and.2, sleeve pipe body 1 and straight-bar 2 are for T-shaped is fixedly connected with, and the end that sleeve pipe body 1 is not connected with straight-bar 2 is fork-shaped tube head 3, and fork-shaped tube head 3 is V-arrangement prong 7, and one side of something of straight-bar 2 is provided with water injection hole 4, and water injection hole 4 is communicated with sleeve pipe body 2.At the fork-shaped tube head one depression bar 5 being set, is observation window 6 between depression bar 5 and the fork-shaped tube head intrados.
Claims (2)
1. a jaw fracture is fixed and is used puncture casing, comprises sleeve pipe body and straight-bar, and it is characterized in that: the sleeve pipe body is that T-shaped is fixedly connected with straight-bar, and the end that the sleeve pipe body is not connected with straight-bar is the fork-shaped tube head; Be provided with depression bar at the fork-shaped tube head; One side of something at straight-bar is provided with water injection hole, and water injection hole is communicated with the sleeve pipe body.
2. puncture casing according to claim 1, it is characterized in that: said fork-shaped tube head is the V-arrangement prong.
