Abstract
The utility model provides an expanding device for the vertebral plate. The expanding device comprises a base, a supporting plate and a limiting rod. The base comprises a fixing plate. A baffle extending out towards the portion above the fixing plate and a limiting portion bent downwards are arranged at one end of the fixing plate, and a screw hole is formed in the other end of the fixing plate. The supporting plate is installed on the base in a rotating mode and provided with a working end and a locating end. The working end and the baffle are arranged on the same side. The limiting rod is connected with the fixing plate and clamps the locating end of the supporting plate. In the use process of the expanding device, the cut rear vertebral plate is lifted and pulled under the rotation effect of the supporting plate, the ligament connected with the bone tissue does not need to be cut, so that unnecessary injury is reduced, and poor recovery of the function of the ligament and postoperation discomfort brought to patients are avoided, and the shortcomings in the prior art are effectively avoided.
Description
Technical field
This utility model relates to a kind of medical aid, relate in particular to a kind of in the time of operation on vertebra the device for spreading for Vertebral laminectomy expanding and shaping.
Background technology
Vertebra canalis spinalis (nerve system of human body penetrating via) is narrow is a kind of disease that needs surgical operation therapy, the main cause that causes this disease is spinal joint degeneration (Degeneration of Joint Disease), and its Clinical symptoms has neuralgia, myalgia and the dyskinesia etc. conventionally.For this disease, in modern clinic treatment, normally used Therapeutic Method is called as vertebral plate expanding and shaping art, in this technology, the rear vertebral plate of vertebra is opened to increase to the volume of canalis spinalis, and then alleviates the diseases such as nerve compression.According to drawing scalloping mode difference, vertebral plate expanding and shaping art is divided into again two kinds of single open-door and double doors.
Single open-door modus operandi is a side of vertebral plate after incision vertebra, then pulling open otch makes rear vertebral plate form " opening the door " to offside upset, due to the asymmetry of single open-door, need excision rear tractive ligament is connected with osseous tissue, but this physical function that can affect patients after surgery recovers and can cause pain, especially axle pain.
Double door modus operandi is along vertebral plate after the midline incision of vertebral plate after vertebra, pulls open otch and makes rear vertebral plate separately form " double door " to both sides.It is very limited that double door expands the space of canalis spinalis, and also cannot retain being connected of rear tractive ligament and osseous tissue, needs to excise.So what double door method was employed is not a lot.
The patent No. is that the Chinese patent of CN203001095U discloses a kind of cervical vertebra open dead plate, comprise vertebral plate fixing head, side plate fixing head and connecting plate, on connecting plate, one end of close vertebral plate fixing head is with clamp, vertebral plate fixing head and clamp composition bayonet socket, described vertebral plate fixing head is mutually vertical with side plate fixing head place plane.Although above-mentioned patent can be applied in vertebral plate expanding and shaping art, its structure is single, can not regulate according to practical situation, also has significant limitation in the time of operation.
In sum, single open-door mode and double door mode all come with some shortcomings, so medical personnel wish to have a kind of new technology can replace prior art always.Through a large amount of research, medical personnel propose a kind of desirable vertebral canal expansion forming method: i.e. vertebral plate from two lateral incision vertebras, by the whole vertebral plate cutting tractive backward, increase intravertebral space, and then fixed-type.This " lifting is opened the door " is simple by the vertebral plate tractive cutting, and can not bend, so can avoid unnecessary ligament cutting, wound is little, is beneficial to post-operative recovery, reduces pain.Due to whole rear vertebral plate promote after in a kind of free state, therefore need the support setting tool of an accurate stable.But going back at present the reliable device of neither one can help doctor to operate safely and steadly the laminoplasty of " lifting is opened the door ".
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Vertebral laminectomy device for spreading of simple in structure, dependable performance, to overcome the above-mentioned defect of prior art.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme: a kind of Vertebral laminectomy device for spreading, is characterized in that: comprise base, gripper shoe and gag lever post; Described base comprises fixing head, and one end of described fixing head is provided with the baffle plate and the reclinate limiting section that stretch out obliquely upward, and the other end of described fixing head is provided with screw hole; Described gripper shoe is rotating to be arranged on base, and described gripper shoe is provided with working end and positioning end, and described working end and described baffle plate are in the same side, and described gag lever post is connected with fixing head and clamps the positioning end of described gripper shoe.
Preferably, the working end of described gripper shoe is bent upwards.
Further, the positioning end of described gripper shoe offers limited mouth, the described gag lever post clamping and positioning end that is connected with the fixing head of described base by limited mouth.
Further, described gag lever post is screw, on described base, has installing hole, and the bar portion of described screw is threaded with the installing hole of described base through limited mouth, and the head of screw matches with fixing head the positioning end of gripper shoe is clamped.
Further, described baffle plate is provided with two side by side in one end of fixing head, and the working end of described gripper shoe is between two baffle plates.
Further, described screw hole is provided with two.
As mentioned above, device of the present utility model, has following beneficial effect:
After this utility model makes bilateral otch, vertebral plate lift technique becomes possibility, and cut rear vertebral plate is promoted tractive by the effect by gripper shoe in the time using this utility model, the ligament that does not need cutting to be connected with osseous tissue, reduce unnecessary wound, the situations such as the postoperative discomfort that has made up the not enough of ligament functional rehabilitation and bring to patient, effectively avoid the defect in prior art, for existing vertebral plate expanding and shaping art development provides an advantage.
