Abstract
The utility model relates to a bone drilling hole protector, which is used in the medical field to control the hole drilling depth during a surgical operation. The utility model comprises a curved and high elastic and adjustable sliding plate, a butterfly shaped bolt, and a Y-shaped positioning plate, wherein, an adjusting sliding groove is arranged on the high elastic and adjustable sliding plate, and the front end of the high elastic and adjustable sliding plate adopts a round obtuse inserting end; An adjusting sliding groove is arranged on the main section of the Y-shaped positioning plate, the two branches of the Y-shaped positioning plate are clipping arms, and pointed clipping nails are respectively connected at the inner sides of the two clipping arms; The high elastic and adjustable sliding plate and the Y-shaped positioning plate are fixedly connected at the adjusting sliding grooves through the butterfly shaped bolt.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of protectors for bone drilling.
Background technology
Now, in the fracture fixation operation, must on skeleton, hole fixedly the time with plate screw, during operation, operator directly towards part only be to cut to peel off the bone portion that the back exposes, and the back of skeleton can not directly be seen, and cutting the scope of peeling off on principle can not be too big, otherwise can influence knitting, therefore, the degree of depth of uncontrollable boring.When the cortical bone of the saturating back of bit drills, it is dark to cause drill bit to thrust as the degree of depth that can not fine keyhole, particularly when the drill bit high speed rotating, is easy to stab or twine muscle, blood vessel, the nerve of damage skeleton back, brings serious consequence.No matter be the doctor that the working time is short, experience is not abundant, or the very high doctor of the age and service seniority all might be taken place.
Summary of the invention
The purpose of this utility model provide a kind of can keyhole when performing an operation the protectors for bone drilling of the degree of depth.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of protectors for bone drilling comprises: the Y shape location-plate of crooked high resiliency adjustable slide plate, wing bolt, bending, and it is characterized in that: have the adjusting chute on the high resiliency adjustable slide plate, high resiliency adjustable slide plate front end is the round blunt shape insertion end; Have the adjusting chute on the trunk section of Y shape location-plate, two of Y shape location-plate branch into the card arm, and two card arm inboards are connected with pointed bail respectively; The high resiliency adjustable slide plate is fixedlyed connected at adjusting chute, adjusting chute place by wing bolt with Y shape location-plate.
Utilize this utility model when holing, can effectively hold the degree of depth of boring, can not make drill bit stab or twine muscle, blood vessel, the nerve of damage skeleton back to skeleton.
Description of drawings
Figure is a structural representation of the present utility model.
In the accompanying drawing:
1, high resiliency adjustable slide plate; 11, round blunt shape insertion end; 12, regulate chute;
2, wing bolt; 3, Y shape location-plate; 31, regulate chute;
32, card arm; 33, pointed bail.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described:
A kind of protectors for bone drilling as shown in the figure, comprising: the Y shape location-plate 3 of crooked high resiliency adjustable slide plate 1, wing bolt 2, bending, and have on the high resiliency adjustable slide plate 1 and regulate chute 12, high resiliency adjustable slide plate 1 front end is a round blunt shape insertion end 11; Have on the trunk section of Y shape location-plate 3 and regulate chute 31, two of Y shape location-plate 3 branch into 32, two cards of card arm arm, 32 inboards and are connected with pointed bail 33 respectively; High resiliency adjustable slide plate 1 is fixedlyed connected at adjusting chute 12, adjusting chute 31 places by wing bolt 2 with Y shape location-plate 3.
This utility model is made by the high resiliency steel disc, be bending under the naturalness when not using, form by high resiliency adjustable slide plate 1 and Y shape location-plate 3 two parts, the end of high resiliency adjustable slide plate 1 is a round blunt shape insertion end 11, and two card arm 32 terminal inboards of Y shape location-plate 3 are respectively equipped with a pointed bail 33.High resiliency adjustable slide plate 1 and Y shape location-plate 3 link together by wing bolt 2 at adjusting chute 12 and adjusting chute 31 places; can high resiliency adjustable slide plate 1 and Y shape location-plate 3 be relatively moved by unscrewing wing bolt 2; to prolong or to shorten this protector, to adapt to the skeleton of different thicknesses, different parts.
When this utility model is manipulated; regulate the length of protector earlier according to the thickness of skeleton; the round blunt shape insertion end 11 of high resiliency adjustable slide plate 1 is inserted to the back of skeleton along the upper limb that partly exposes skeleton; the card arm 32 of Y shape location-plate 3 is positioned at the exposure (being this one side that operator is faced) of skeleton; protector blocks skeleton by the elastical retraction of himself; pointed bail 33 avoids two card arms 32 to move attached to bone surface; midline position at two card arm 32 angles can be holed; when drill bit penetrates into the skeleton opposite; then must touch the steel disc of round blunt shape insertion end 11, thereby protect the blood vessel of skeleton rear side definitely; muscle; tissues such as nerve.
After boring finishes, with the depth finder thickness of energy measurement skeleton also so that the screw of selecting to be fit to fixes, from and brought into play adjection of the present utility model.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
