Abstract
The utility model relates to a minimally invasive craniotome comprising a driving device and a cutter, wherein the driving device and the cutter are connected by a transmission mechanism, and the cutter is an annular cutter. Compared with the design of an original drill bit, the annular cutter can reduce the area of the injured skull of a patient as far as possible, and a doctor can take out the skull of an opening part integrally; after the operation is finished, the taken-down skull is placed back to the original position of the patient by a medical technology, which shortens the periods of treatment and rehabilitation; and moreover, the magnitude of the size of the annular cutter can also be custom-made according to the special requirement of a user.
Description
Technical field
This utility model design relates to a kind of armarium, refers to a kind of Wicresoft's craniotome of cerebral operations especially.
Background technology
When being carried out surgical operation, brain often needs to use craniotome, traditional craniotome is a principle of utilizing power drill, utilize drill bit that head is burrowed, the skull of opening portion is pulverized fully when still utilizing this kind device, is unfavorable for the integrated degree and the recovery period of patient's head; And the drill bit of the craniotome that this kind is traditional all is to carry out high speed rotary motion to same direction when using, drill bit can stop operating automatically when punching skull, but because inertia, drill bit still can change certain distance in cranial cavity, will destroy brain tissue like this, serious even cause death.
Summary of the invention
The technical problem that this utility model design will solve is to provide a kind of novel cranium equipment of opening, need when opening cranium, can guarantee the complete taking-up rather than the pulverizing of skull of opening portion, thereby shorten patient's treatment and recovery period and the integrated degree that has guaranteed patient's head.
For solving the problems of the technologies described above, this utility model design provides a kind of Wicresoft craniotome, comprises driving device and cutter, is connected by drive mechanism between described driving device and the cutter, and wherein: described cutter is an annular cutter.
Than original drill bit design, annular cutter can reduce the area of patient trauma skull as much as possible, the doctor can the complete taking-up with the skull of opening portion, Deng the operation finish after, again so that the skull that takes off is put back to the original position of patient by medical skill, shortened treatment and recovery period, and this annular cutter can also be according to user's specific (special) requirements size customized.
The further improvement of this utility model design is, described drive mechanism comprises: one first driving member, one end of described first driving member is provided with power intake, described power intake and described driving device are in transmission connection, the other end of described first driving member is provided with clutch end, and described clutch end and described power intake are eccentric design; One second driving member, described second driving member comprises a driving shaft and a driven shaft, the outfan of described driving shaft and described first driving member is in transmission connection; One the 3rd driving member, described the 3rd driving member comprises a power transmission shaft, and hanging down at an end of described rotating shaft is provided with a link, and the driven shaft of described link and described second driving member is in transmission connection, and described power transmission shaft and described annular cutter are in transmission connection.Can realize the reciprocating motion of annular cutter by above-mentioned drive mechanism, rather than carry out high speed rotating, can significantly reduce the destruction of patient's soft tissue like this to same direction.
The further improvement of this utility model design is that the outfan of the driving shaft of described second driving member and described first driving member is in transmission connection by bearing; The driven shaft of the link of described the 3rd driving member and described second driving member is in transmission connection by bearing.Can make in swing process rolling friction replace sliding friction by the bearing transmission, thereby frictional force and noise can be dropped to minimum, kinetic energy is strengthened greatly.

The specific embodiment
Design is further described to this utility model below in conjunction with accompanying drawing.
At first consult shown in Figure 1ly, Wicresoft's craniotome 1 of this utility model design mainly comprises driving device 10, annular cutter 20 and drive mechanism 30, wherein:
Driving device 10 is a motor, and it is arranged on the motor cabinet 11, also is provided with motor shaft 12 on the motor and is used for to external transmission power;
Cooperate shown in Fig. 2 a, the 2b, it is one cylindric that annular cutter 20 roughly is, and comprises link 21 and annular cutter head 22, and this annular cutter head 22 is similar to one " rim of a cup ", along should " rim of a cup " week being formed with sawtooth;
Cooperate shown in Figure 3, it is one cylindric that first driving member 31 also roughly is, the through hole of a series of vary in diameter runs through first driving member 31 vertically, forms a power intake 311 at an end of first driving member 31, and this power intake 311 keeps coaxial design with whole first driving member 31; The other end at first driving member 31 forms a clutch end 312, and this clutch end 312 does not overlap with the central shaft of power intake 311, therefore is eccentric design; Be embedded with a hexagonal axle sleeve 313 in the power intake 311, motor shaft 12 plugs into being in transmission connection with power intake 311 formation in this hexagonal axle sleeve 313 and thus;
Cooperate shown in Figure 4, second driving member 32 comprises an intermediate connector 321, be formed with a driving shaft 322 and a driven shaft 323 respectively at the two ends of intermediate connector 321, driving shaft 322 plugs in the clutch end 312 of aforementioned first driving member 31, and keeps being in transmission connection by bearing group 324 and clutch end 312; Driven shaft 323 then is further used for transmitting kinetic energy to the 3rd driving member 33;
Cooperate shown in Figure 5, the 3rd driving member 33 comprises a power transmission shaft 331, at the vertical link 332 that is provided with of an end of power transmission shaft 331, aforesaid driven shaft 323 plugs in this link 332, and keep being in transmission connection by bearing group 333 and link 332 equally, be folded with spacer ring 334 between each two-part bearing of bearing group 333 and make the two-part bearing can positioning; Link 21 formation that power transmission shaft 331 passes an eccentric bushing 335 and annular cutter 20 are in transmission connection, and borrow 335 pairs of power transmission shafts 331 of this eccentric bushing that an effect of setting up is provided;
Further cooperate shown in Figure 1, when Wicresoft of the present invention craniotome 1 uses, the annular cutter 20 that is used to perform the operation is installed earlier, aiming at patient's head needs the part of opening, muzzle is vertical or be with angle all can, start driving device 10, thereby motor shaft 12 drive hexagonal axle sleeves 313 drive first driving member 31 and carry out the circumference rotation, because the off-centre of clutch end 312 design, further the driving shaft 322 that drives second driving member 32 is slightly swung, back and forth rotate thereby drive driven shaft 323, and driven shaft 323 further drives back and forth rotation of annular cutter 20 generations; Because the design of the annular cutter head 22 of annular cutter 20, can complete taking-up with the skull of opening portion, waiting operation to finish after, so that a skull that takes off is put back to the original position of patient by medical skill, shortened treatment and recovery period again; And, by first driving member 31, the cooperation of second driving member 32 and the 3rd driving member 33 is converted into same direction high speed rotating the reciprocal rotation of cutter, even touch meninges or brain tissue, owing to be to move back and forth, annular cutter 20 can not form tissue and seriously influence, and compares the same direction damaged condition that rotatablely moves and is much smaller; And owing to utilize bearing transmission kinetic energy in the drive mechanism 30, frictional force is very little almost can ignore, and the noise that so also begins drops to minimum, and machine also is difficult for hot in working long hours.
