Description
Technical field
This utility model relates to a kind of orthopaedic medical treatment device, specifically, relates to the directed dilator of a kind of percutaneous sacculus.
Background technology
Osteoporotic Vertebral Compression Fractures often causes patient pain, limitation of activity, and particularly along with aging degree increases, the sickness rate of Osteoporotic Vertebral Compression Fractures rises year by year.Traditional Therapeutic Method, for lying up, promotes bone absorption by medicine, reduces bone and dissolves and analgesia process.But the course for the treatment of of this Therapeutic Method is longer, and uncertain therapeutic efficacy is cut.Balloon angioplasty vertebroplasty is a kind of effective ways for the treatment of this type of fracture grown up in recent years, therapeutic process be roughly percutaneous puncture vertebral body inject bone cement or first strut compression with sacculus vertebral body after the bone cement that reinjects carry out Vertebroplasty, to reach stable fracture, to recover vertebral body mechanical strength and lenitive object.The Therapeutic Method of balloon angioplasty vertebroplasty is comparatively simple, but over the course for the treatment of, sacculus cannot orientation strut, and causes bone cement to expose, easily causes blood vesssls and nerves injuries, even causes serious complication, has a strong impact on the operative treatment situation of patient.
Utility model content
The purpose of this utility model is to provide the directed dilator of a kind of percutaneous sacculus, orientablely struts vertebral body, effectively reduces bone cement and exposes.
The technical solution of the utility model is: the directed dilator of a kind of percutaneous sacculus, this device is primarily of handle and working column composition, it is characterized in that: described working column is closed hollow sleeve, described sleeve pipe is stainless pipe, the nearly sacculus end of described working column is provided with oval side opening, the edge of described oval side opening is set to smooth, the long service capsule end of described working column is connected with handle, the connected mode of described working column and described handle is for being threaded, the length regulating described working column is rotated by described handle, described handle upper end is provided with the fastening bolt of steady job sleeve pipe.
Preferably, the distance of the nearly sacculus end of described oval side opening and described working column is 0.3 ~ 0.5mm.
Preferably, described handle is T-handle, and the surface of described T-handle is provided with anti-slip veins.
Preferably, described working column surface is provided with the rule positioned for strutting process to sacculus.
Preferably, the major axis dimension of described oval side opening is 1cm.
This utility model beneficial effect is compared with prior art:
(1) working column adopts closed hollow sleeve, and the nearly sacculus end of working column is provided with oval side opening, can carry out unidirectional orientation strut sacculus, assists the reduction of the fracture, effectively reduces bone cement and exposes;
(2) working column and the connected mode of handle are for being threaded, the length regulating working column is rotated by handle, and by the fastening bolt of handle upper end, working column is fixed, handle surfaces is provided with the rule positioned for strutting process to sacculus, the length of working column can be regulated according to concrete Treatment need, convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For making the object of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is the embodiment of this utility model part, instead of whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those skilled in the art obtain under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
Embodiment 1
The directed dilator of a kind of percutaneous sacculus, for osteoporotic vertebral operative treatment.This device forms primarily of handle 1 and working column 2, and structure is simple and convenient, orientablely struts vertebral body, effectively reduces bone cement and exposes.
Working column 2 is closed hollow sleeve, light quality.Sleeve pipe is stainless pipe, and the nearly sacculus end of working column 2 is provided with oval side opening 3, and the size of oval side opening 3 just allows sacculus strut and pass, and the edge of oval side opening 3 is set to smooth, avoids causing sacculus to destroy.The long service capsule end of working column 2 is connected with handle, the connected mode of working column 2 and handle 1 is for being threaded, the length regulating working column 2 is rotated by handle 1, handle 1 upper end is provided with the fastening bolt 4 of steady job sleeve pipe 2, user can regulate the length of working column according to concrete Treatment need, convenient and practical.
For realizing preferably therapeutic effect, oval side opening 3 is set to 0.3 ~ 0.5mm with the distance of the nearly sacculus end of working column 2, and the major axis dimension of oval side opening is 1cm.
For preventing handle in art from skidding, handle 1 is set to T-handle, and the surface of T-handle is provided with anti-slip veins, facilitates taking.
Measure for convenience of in therapeutic process the degree of depth that probes into of working column 2 and locate, working column 2 surface is provided with the rule positioned for strutting process to sacculus.
Those skilled in the art can understand the schematic diagram that accompanying drawing is only a preferred embodiment, and the structure in accompanying drawing might not be that to implement this utility model necessary with composition.
It is last it is noted that above embodiment is only for illustration of the technical solution of the utility model, but not be limited, although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of this utility model.
