Abstract
The utility model relates to a manual depth-limiting drill with an atlantal vertebral pedicle location-guide function, aiming at providing a manual depth-limiting drill with an atlantal vertebral pedicle location-guide function, and capable of reducing a surgical risk, ensuring a surgical effect, reducing the blood loss volume of a patient, and saving auxiliary personnel. The manual depth-limiting drill disclosed by the utility model comprises a drill rod, a drill sleeve, an arc-shaped vertebral pedicle location seat, an anti-rotation location rod and a rod seat, wherein the drill rod is arranged in the drill sleeve in a penetrating manner and in threaded connection with the drill sleeve; the rod seat is fixedly connected to the head portion of the drill sleeve; one end of the anti-rotation location rod is fixedly connected with the rod seat and extends along the drill bit direction of the drill rod; the other end of the anti-rotation location rod is fixedly connected with the arc-shaped vertebral pedicle location seat.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to a kind of manual depth stop brill of positioning and guiding of putting the use of nail fixing operation for neck lepospondylous pedicle of vertebral arch.
Background technology
The lepospondylous pedicle of vertebral arch of mankind's cervical region is around being adjoined important blood vessel and nerve, and carrying out lepospondylous pedicle of vertebral arch while putting nail fixing operation, operating difficulty is large, and risk is high.At present, lepospondylous pedicle of vertebral arch is put the multiplex manual depth stop of nail fixing operation and has been bored, due to the defect of structural design, in art, the dissection witness marker of this brill is unintelligible, location is difficult for accurately, for guaranteeing operation quality and effect, must adopt nerve dissector to isolate lepospondylous pedicle of vertebral arch lower edge and medial wall, avoid damaging arteries.In nerve dissector separation process, patient's bleeding is many, and operative doctor relies on naked eyes location inaccurate, and poor stability needs to continue tractive dural sac and nerve root, and wants assistant and patient to cooperatively interact, otherwise very easily causes secondary damage.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of manual depth stop brill of atlas pedicle of vertebral arch positioning and guiding that reduces operation risk, assurance surgical effect, reduces patient's blood loss, saving paraprofessional personnel.
For reaching above-mentioned purpose, the manual depth stop of this utility model atlas pedicle of vertebral arch positioning and guiding is bored, comprise drilling rod, drill bushing, arc pedicle of vertebral arch positioning seat, anti-locating rod and the pole socket of revolving, described drilling rod is arranged in described drill bushing inside and is threaded with described drill bushing, described pole socket is fixedly connected on described drill bushing head, describedly anti-revolve that locating rod one end is fixedly connected with described pole socket and extend along the drill bit direction of described drilling rod, describedly preventing that revolving the locating rod other end is fixedly connected with described arc pedicle of vertebral arch positioning seat.
Wherein also comprise handle, described handle is connected in described drill bushing afterbody.
The manual depth stop of this utility model atlas pedicle of vertebral arch positioning and guiding is bored difference from prior art and is that this utility model obtained following technique effect:
1, the manual depth stop brill of this utility model atlas pedicle of vertebral arch positioning and guiding is simple in structure, cheap for manufacturing cost, uses operation simple and convenient in art, and lepospondylous pedicle of vertebral arch witness marker is clear, drilling rod accurate positioning;
2, use the manual depth stop of this utility model atlas pedicle of vertebral arch positioning and guiding to bore without adopting nerve dissector to isolate lepospondylous pedicle of vertebral arch lower edge and medial wall, good operation effect, risk is low, and patient loses blood few, saves assist personnel.
Below in conjunction with accompanying drawing, the manual depth stop of atlas pedicle of vertebral arch positioning and guiding of the present utility model is bored and is described further.
Accompanying drawing explanation
Fig. 1 is that the manual depth stop of atlas pedicle of vertebral arch positioning and guiding is bored population structure schematic diagram;
Fig. 2 is the left view of Fig. 1.
Description of reference numerals: 1-drilling rod; 2-drill bushing; 3-pole socket; The anti-locating rod that revolves of 4-; 5-arc pedicle of vertebral arch positioning seat; 6-handle.
The specific embodiment
Below in conjunction with drawings and Examples, technical characterictic and the advantage with other above-mentioned to this utility model are described in more detail.
The manual depth stop of this utility model atlas pedicle of vertebral arch positioning and guiding is bored, comprise drilling rod 1, pole socket 3, anti-locating rod 4 and the arc pedicle of vertebral arch positioning seat 5 of revolving, drilling rod 1 is arranged in drill bushing 2 inside and is threaded with drill bushing 2, so that drilling rod 1 axially-movable in the interior rotation of drill bushing 2, pole socket 3 is fixedly connected on drill bushing 2 heads, anti-revolve that locating rod 4 one end are fixedly connected with pole socket 2 and along the drill bit direction extension of drilling rod 1, prevent that revolving locating rod 4 other ends is fixedly connected with arc pedicle of vertebral arch positioning seat 5, drill bushing 2 afterbodys have handle 6.
In the time that operation is used, first arc pedicle of vertebral arch positioning seat 5 is leaned on patient's lepospondylous pedicle of vertebral arch medial wall and lower wall position, utilize the planform of lepospondylous pedicle of vertebral arch and coordinating of arc pedicle of vertebral arch positioning seat 5, make described manual depth stop bore integral circumferential and radially accurately locate, now, one holds the handle 6 that described manual depth stop is bored, adjust after the angle of described manual depth stop brill, keep stationary state, another hands rotates drilling rod 1, make drilling rod 1 carry out axially-movable in the interior rotation of drill bushing 2, accurately complete in lepospondylous pedicle of vertebral arch and hole.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of this utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of this utility model claims.
Claims (2)
