Description
Technical field
This utility model belongs to surgical operation medical apparatus technical field, particularly relates to a kind of medical cranial brain drill bit.
Background technology
When carrying out operation of opening cranium, usually drilling tool will be used to hole on hard skull, due to skull inner close fitting is meninges, require that drill bit can bore skull but not injure meninges, brill cranium is in the past all the feel and the experience that rely on doctor, will cause the accident unless you give your whole attention to it, operating difficulty is high, have a big risk, thickness due to the skull of people is generally 1 ~ 1.5 centimetre, so when sphenotresia, needs to arrange stopping means, to prevent drill bit after penetrating skull, continue deeply injured brain tissue.Although this device can effectively avoid excessively deeply entering of drill bit, if there is deviation between the position that stopping means contingency lost efficacy or stopping means is fixing in operation and skull, will injured brain tissue be caused, cause irreversible surgical consequences.
The patent No. is that the Chinese patent of CN204293220U provides a kind of drill for craniotomy drill bit, the external diameter of bit head is greater than by the diameter arranging conductive bar, to form hierarchic structure, thus ensure to there is deviation when other stopping means lost efficacy or between its position and skull, after bit head enters skull completely, conductive bar can be stuck on skull, avoids bit head to go deep into and injured brain tissue further.But this structure just prevents stopping means to lose efficacy, and itself can not play this effect, can not be used alone, still need with stereotactic surgery instrument with the use of.
Another kind of craniotome drill utilizes the master be nested, secondary drill bit realizes when stall rapid after the saturating skull of main bit drills, stopping brill is utilize spring will lead when boring saturating skull, it is right that secondary brill departs from, if slightly do not noted in the process departed from, main drill bit also can be rotated further the damage causing meninges, the patent No. is that the Chinese patent of CN203591296U discloses a kind of craniotome drill, the main drill chuck head arranged in sliding sleeve facing groove slips into ramp structure, make medical personnel handle bore time from stopping getting into the process of spudding in, dop enter the sense that groove does not steadily have kick, main brill can be realized more reliably once penetrate skull just reliably can stop brill at once, solve owing to being used alone the de-brill of spring, make operation more safe and reliable.But this structure entirety is more complicated, dismounting is inconvenient, and cost is higher.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of medical cranial brain drill bit, can be used alone, do not need with the positioner of stereotactic surgery instrument with the use of, eliminate the hidden danger that stopping means inefficacy exists, more safe and reliable.
To achieve these goals, this utility model adopts following technical scheme:
A kind of medical cranial brain drill bit, comprise drill main body, characterized by further comprising stop, rig connecting rod, described stop is provided with drill bit spacing hole, described drill main body one end is fixedly connected with described stop through described drill bit spacing hole, the described drill main body other end is fixedly connected with described rig connecting rod, and described drill main body front end is provided with screw thread.
Described stop comprises rotary part and fixed part, bearing one is provided with in described rotary part, bearing two is provided with in described fixed part, described rotary part and described fixed part are connected with described bearing two by described bearing one, described fixed part be respectively equipped with size, through hole that shape is identical in the middle part of described rotary part, described two through holes form described drill bit spacing hole, and centrage on the same line.
The diameter of described drill bit spacing hole is greater than the external diameter of described drill main body, and is less than the Breadth Maximum of described rig connecting rod cross section.
Described rotary part sidepiece is provided with fixing hole, and the direction, aperture of described fixing hole is vertical with the direction, aperture of described drill bit spacing hole, and described drill main body is fixedly connected with described rotary part by described fixing hole, fixture.
Described rotary part and described fixed part are cylindrical, and the diameter of described rotary part is less than the diameter of described fixed part.
Described drill main body and described rig connecting rod are formed in one structure.
The beneficial effects of the utility model are: drill main body is provided with screw thread, can limit the degree of depth piercing scalp; Drill main body is connected by fixing hole and fixture with stop, and what make drill main body pierces depth adjustment; By the effect of bearing one and bearing two, after reaching certain displacement, rotary part can dally relative to fixed part, position-limiting action can be played to drill main body, effectively prevent drill main body from creeping into the position of head excessively dark, thus ensure that the safety of patient in operative process; And the diameter that the diameter of rotary part is less than fixed part further increases the safety of operation, encounters head periphery when preventing rotary part from rotating; In addition stop of the present utility model and drill main body overall structure simple, easy accessibility, cost of manufacture is low, operate easy to adjust, stop and drill main body form an entirety, can be used alone, do not need with the positioner of stereotactic surgery instrument with the use of, eliminate the hidden danger that stopping means inefficacy exists, more safe and reliable.
