Abstract
The utility model provides a sleeve type bone driller, which comprises a common bone driller and a measuring pole. The utility model is characterized in that a heave head of a movable sleeve is fixed and connected with a concave slot of the measuring pole through a screw. The measuring pole is inserted into a movable safe slide block and a corresponding hole of a bracket. Another end of the sleeve is a movable tooth shaped semi-concave structure. The inner diameter and the length of the sleeve can be made into many types. The utility model uses the sleeve structure to prevent the parenchyma along the drilling hole from being damaged, uses the measuring pole to observe the needle depth dynamically, and uses the safe slide block to control the depth of the drilling hole. So the utility model has the advantages of safety, convenience, fast and much smaller damage for the drilling operation.
Description
Technical field
This utility model belongs to medical apparatus and instruments.
Background technology
At present the open reduction internal fixation of fracture operation be unable to do without hand or electric bone drill clinically, and there is following defective in present used bone drill tool: 1, because effect of inertia, easily cause the offside soft tissue injury when penetrating eventually not sclerotin, cause blood vessel or nerve injury; Its boring surrounding tissue was not thoroughly easily hindered by strand because of retracting when 2, drill bit or pin pierced; 3, drilling depth needs secondary to measure, and bothers time-consuming again.4, operator must be in the height biotonus for preventing offside tissue injury in the boring procedure.
Summary of the invention
The purpose of this utility model provides a kind of telescopic bone drill, it is by tube-in-tube structure prevent to hole surrounding soft tissue damage, dynamic observe depth of needle with measuring stick, with the insurance slide block keyhole degree of depth, reaching operation boring safety, easily and fast, the little advantage of damage.
The purpose of this utility model is achieved through the following technical solutions, telescopic bone drill, it has common bone drill and measuring stick, it is characterized in that: the plush copper of quill is fixedlyed connected by screw with the Baltimore groove of measuring stick end, and measuring stick is inserted in the corresponding aperture that slidably insures slide block and support.The telescopic other end is movable dentation dished structure.Telescopic internal diameter and length can be made into multiple model.
The beneficial effects of the utility model are not damage offside soft tissue face to cause blood vessel or nerve injury in the middle of operation, do not need secondary to measure, save time, laborsaving, can be by tube-in-tube structure prevent to hole surrounding soft tissue damage, dynamic observe depth of needle with measuring stick, with the insurance slide block keyhole degree of depth, reaching operation boring safety, easily and fast, the little advantage of damage.
Description of drawings
Fig. 1 is a main TV structure sketch map of the present utility model;
Fig. 2 is that the A-A of measuring stick 1 among Fig. 1 is to cutaway view;
Fig. 3 is the structural representation of quill 5 among Fig. 1.
Among the figure, 1 is that measuring stick, 2 is diaphysis for dentation dished structure, 10 for bone drill, 9 for Kirschner wire or drill bit, 8 for holding screw, 7 for quill, 6 for spring, 5 for support, 4 for insurance slide block, 3.
The specific embodiment
Telescopic bone drill, it has common bone drill 8 and measuring stick 1, it is characterized in that: the plush copper of quill 5 is fixedlyed connected by screw 6 with the Baltimore groove of measuring stick 1 end, and measuring stick 1 is inserted in the corresponding aperture that slidably insures slide block 2 and support 3.The other end of sleeve 5 is movable dentation dished structure 9.The internal diameter of sleeve 5 and length can be made into multiple model.
According to waiting to hole position size and surrounding soft tissue's situation, at first select the quill 5 of suitable types during use, and fixing with holding screw 6 with measuring stick 1, and it is fixing with bone drill 8 to select Kirschner wire or drill bit to pass quill 5 backs then; During boring, dentation dished structure 9 is tight against diaphysis 10 can prevents that drill bit or Kirschner wire from sliding on surface of bone.Sleeve 5 can need be made multiple model according to internal diameter and length.
Claims (3)
1, telescopic bone drill, it has common bone drill (8) and measuring stick (1), it is characterized in that: the plush copper of quill (5) is fixedlyed connected by screw (6) with the Baltimore groove of measuring stick (1) end, and measuring stick (1) is inserted in the corresponding aperture that slidably insures slide block (2) and support (3).
2, telescopic bone drill according to claim 1 is characterized in that: the other end of sleeve (5) is a movable dentation dished structure (9).
3, telescopic bone drill according to claim 1 is characterized in that: the internal diameter and the length of sleeve (5) can be made into multiple model.
