The cut material of air vent sucking-off.
Refer to Fig. 8, the embodiment of the present invention additionally provides a kind of operational approach based on any of the above-described described operating theater instruments,
The method may comprise steps of:
Step 801: feedback device obtains the O&M information of surgical knife head, and it is defeated that described O&M information is sent to power
Go out device.
Wherein, O&M information includes: the type of described surgical knife head, the frictional force correction of described surgical knife head are
At least one in the current rotating speed of surgical knife head several, described and the current moment of described surgical knife head.
When operating theater instruments just begins to use, O&M acquisition of information can be sent by PTO to feedback device and refer to
Order, the feedback device type by the surgical knife head in O&M information and the frictional force correction coefficient of described surgical knife head, send out
Give PTO.
Feedback device current rotating speed and current moment to surgical knife head in real time is monitored, and once monitors scalpel
The current rotating speed of cutter head and current moment, it is possible to use the time period of setting, fed back to PTO every this time period
The once current rotating speed of this surgical knife head and current moment, so that PTO is moved according to the O&M information of feedback
The adjustment of power.
Step 802: PTO, according to described O&M information, exports the power of corresponding gear.
The type of surgical knife head and the corresponding relation of gear can be provided with in PTO.Export at power
When device receives type and the frictional force correction coefficient of the surgical knife head that feedback device sends, can be according to surgical knife head
Type determine the power of corresponding gear, and according to frictional force correction coefficient, this gear determined is adjusted accordingly, and will
The power that gear after adjustment is corresponding exports.
In operating theater instruments work process, PTO can be fed back according to receive every a time period
The current rotating speed of the surgical knife head of device feedback and current moment, adjust accordingly gear, thereby may be ensured that operation
Jet blade can have the rotating speed being more suitable for and moment in the course of the work.
Step 803: driving shaft enters around the axis of described driving shaft under the power drive that described PTO exports
The rotary motion of row corresponding speed.
The power that the speed that driving shaft is rotated exports with PTO is relevant, if PTO is defeated
The rotating speed going out power is 2000r/min, then the speed that driving shaft is rotated is similarly 2000r/min.
Step 804: power transmission shaft is under the driving of described driving shaft, and the axis around described power transmission shaft carries out the rotation of corresponding speed
Transport axis direction that is dynamic and that prolong described power transmission shaft and carry out the reciprocating motion of corresponding speed.
Driving shaft is when being rotated, and the first gear being enclosed within driving shaft is carried out and the rotation of driving shaft equidirectional
Transhipment is dynamic, and first gear driven the second gear carries out rotary motion rightabout with driving shaft, and the second geared sleeve is at power transmission shaft
On, power transmission shaft therefore can be driven to carry out rotary motion rightabout with driving shaft.
Driving shaft is when being rotated, and due to the two-way leading screw arranged on driving shaft, the slide block being enclosed within driving shaft can
Move back and forth with the axis direction along driving shaft, be enclosed within equally on power transmission shaft due to slide block, therefore, it can at stopping means
Position-limiting action under, drive power transmission shaft move back and forth.
Step 805: surgical knife head utilizes blade to excise non-normal tissue under the drive of described power transmission shaft.
This operation process is carried out under the mirror of chamber, and therefore medical personnel can find by the observation of chamber mirror that patient's is non-
Normal structure, such as, tumor, by surgical knife head to prospective tumor, and then tumor can be excised.
Step 806: internal by the tubular structure of described surgical knife head and described power transmission shaft the tubulose of adsorbent equipment is tied
By cut material sucking-off inside structure.
Owing to operation process is carried out in vivo, therefore, internal in order to ensure that cut material is not left in, or, for
Prevent from needing opening with patient bigger wound taking out cut material, cause to patient and further damage, permissible
Utilize adsorbent equipment can utilize motor output power so that the impeller in adsorbent equipment rotates under power drive, with
Push the air into air vent, when forming air pressure difference between air inlet and air vent, by described cut material from described
It is drawn into inside the tubular structure of surgical knife head inside the tubular structure of described power transmission shaft, and ties from the tubulose of described power transmission shaft
It is drawn into described air inlet inside structure, and is drawn into described air vent from described air inlet, and then be placed in storage tank.
To sum up, each embodiment of present invention beneficial effect specific as follows:
1, in embodiments of the present invention, the O&M information output fed back according to feedback device by PTO is corresponding
The power of gear, during to drive driving shaft to be rotated, can drive power transmission shaft to be rotated and move back and forth, hands
Art jet blade is rotated under the drive of power transmission shaft and moves back and forth, in motor process, it is possible to achieve to entering cutter
