Abstract
The utility model provides a soft tissue drag hook, including handheld handle and hook end, its characterized in that, catching hold of the end with a hook and setting up to elongated hook end and weak point type hook end, elongated hook end and short type hook end are all held the body and are connected in the infolding portion of hook end body lower extreme including the hook, infolding portion forms an angle with hook end body, and the hook end body of elongated hook end and short type hook end is connected with the both ends chamfer of handheld handle respectively, and hook end body is perpendicular with handheld handle. The utility model discloses soft tissue drag hook, the broken ends of fractured bone screw of conveniently fracturing is put into, saves operation time, reduces the operation cost, reduces postoperative complication's emergence, improves the comfortable degree that art person handed, more reduces the cutting action of drag hook to the soft tissue.
Description
Technical field
This utility model relates to a kind of dural retractor, belongs to surgical device technical field.
Background technology
Along with the development of contemporary surgery, the idea of Wicresoft is rooted in the hearts of the people gradually.Orthopedist wishes well to reset and the extent of exfoliation as far as possible reducing fracture end soft tissue under stablizing fixing prerequisite, so Reduction surgery otch obtains the common recognition of doctor reaching fracture site.And otch reduce the difficulty must bringing exposure of surgical field, affect accurately inserting of bone surgery light plate screw.In operation process, often need soft tissue in dural retractor tractive art, fully appear the visual field, be beneficial to operation and carry out.The good surgical operation especially that appears successfully ensures.But conventional dural retractor, because the defect of its profile, often makes to insert steel plate screw difficulty in bone surgery, especially all the more so for the position that soft tissue attachment is abundant.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of dural retractor, facilitates fracture site screw to insert, and saves operating time, reduce operation cost, reduce the generation of post-operative complication, improve the level of comfort that patient is hand-held, more reduce drag hook to the dissection of soft tissue.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of dural retractor, comprise hand holding handle and hook end, described hook end is set to elongated hook end and short hook end, elongated hook end and short hook end include hook end body and are connected to the inflexed part of hook end body lower end, at angle, elongated hook end is connected with the both ends chamfering of hand holding handle respectively with the hook end body of short hook end, and hook end body is vertical with hand holding handle for described inflexed part and hook end body shape.
Further, arc hollow out in the middle part of described hand holding handle.The counteracting force of handle opponent when available buffer is hand-held.
Further, described hook end body surface arranges groove, and described groove extends to hand holding handle upper surface from inflexed part.The inserting of screw when facilitating bone surgery, saves operating time, reduces operation cost, more reduce the generation of post-operative complication.
Further, the groove two edges of hook end body are provided with scale.Measuring bolt length during the inserting or take out of screw when facilitating bone surgery.
Further, hand holding handle length is 15-25cm.
Further, recess width 3-6mm.
Further, elongated hook end length is 5.5-8.5cm, and short hook end length is 4.0-6.0cm.The needs of Be unlike skill style can be met.
Further, the radius of described chamfering is 8-12mm.Reduce stress to concentrate, alleviate the stimulation to soft tissue.
Further, the angle ranging from 120 °-130 °.The hold of hook end and soft tissue can be increased.
Further, drag hook integral edge is set to the rounding that radius is 0.5-2.0mm.Improve the level of comfort that patient is hand-held, more reduce drag hook to the dissection of soft tissue.
Compared with prior art, this utility model dural retractor, the counteracting force of handle opponent when medial arc hollow out device buffering is hand-held; When the design of both sides 3-6mm diameter grooves facilitates bone surgery, screw is inserted, and saves operating time, reduces operation cost, more reduce the generation of post-operative complication; Hook end length etc. can not meet the needs of Be unlike skill style; Hook end and hand holding handle intersection rounding design and reduce stress and concentrate, and alleviate the stimulation to soft tissue; The rounding design of drag hook edge can improve the hand-held level of comfort of patient, more reduces drag hook to the dissection of soft tissue; When hook end scale facilitates bone surgery, measuring bolt length during the inserting or take out of screw, saves operating time.

Each parts mark in accompanying drawing: 1-hand holding handle, 2-groove, 3-chamfering, 4-elongated hook end, 5-scale, 6-inflexed part, 7-edge, 8-arc hollow out, 9-short hook end.
Detailed description of the invention
Dural retractor as shown in Figure 1, comprise hand holding handle 1 and hook end, described hook end is set to elongated hook end 4 and short hook end 9, elongated hook end and short hook end include hook end body and are connected to the inflexed part 6 of hook end body lower end, the angle that described inflexed part 6 and hook end body are formed is 120 °-130 °, can increase the hold of hook end and soft tissue, elongated hook end is connected with the both ends chamfering of hand holding handle respectively with the hook end body of short hook end, and hook end body is vertical with hand holding handle.Arc hollow out 8 is provided with in the middle part of hand holding handle.The counteracting force of handle opponent when available buffer is hand-held.Institute's hook end body surface arranges groove 2, and described groove extends to hand holding handle upper surface from inflexed part.The inserting of screw when facilitating bone surgery, saves operating time, reduces operation cost, more reduce the generation of post-operative complication.The groove two edges of hook end body are provided with scale 5.Measuring bolt length during the inserting or take out of screw when facilitating bone surgery.Hand holding handle length is 15-25cm, recess width 3-6mm.Elongated hook end length is 5.5-8.5cm, and short hook end length is 4.0-6.0cm.The needs of Be unlike skill style can be met.The radius of chamfering is 8-12mm.Reduce stress to concentrate, alleviate the stimulation to soft tissue.Drag hook integral edge is set to the rounding that radius is 0.5-2.0mm.Improve the level of comfort that patient is hand-held, more reduce drag hook to the dissection of soft tissue.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from this utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of this utility model request protection, all records in detail in the claims.
