In conjunction with the accompanying drawings this utility model is elaborated again below.
Fig. 1 to Fig. 5 shows structure chart of the present utility model.Be used for that the multivariant hemostasis sickle of hand-held comprises tool bar 1 under the mirror of chamber, be installed on the deflecting wheel 93 at tool bar 1 two ends rotatably by deflection wheel shaft 91, by pilot hole 90 two auxilliary directive wheels 11 are installed, two main directive wheels 10 on installation and the deflection wheel shaft 91.The centrage that is arranged at the guiding race on auxilliary directive wheel 11 and the main directive wheel 10 is tangent.Be provided with race 931 on described deflecting wheel 93, deflection driving wire 13 is connecting two deflecting wheels 93 up and down that are positioned on the described tool bar 1 by described race.
Be installed on the rotation mount pad 92 and setting and from swivel base anchor tip 121 being fixedly linked from swivel base 12 on of deflecting wheel 93 by being provided with on it of tool bar 1 bottom.Be provided with from adaptor 122 from swivel base 12, turning certainly 2 is installed on adaptor 122 rotatably.Certainly turning 2 is provided with the sickle head 3 of moving linearly thereon, is set with operation pin I4, operation pin II5, operation pin III6, operation pin IV7 on sickle head 3.Wherein operating pin I4 is one group with operation pin II5, and links to each other with lead I31; Operation pin III6 and operation pin IV7 are one group, and link to each other with lead II32.Lead I31 and lead II32 pass described tool bar 1, and link to each other with interface 33 on being arranged on tool bar 1, and interface 33 can link to each other with the external energy generator.The structure of each parts that is installed on tool bar 1 top is basic identical with the structure of each parts that is installed on tool bar 1 bottom, just by be installed on the operating grip 8 of top on swivel base 12 rotatably from adaptor 122.Sickle head 3 can be provided with and do reciprocating linear motion on 2 from turning certainly under the effect of the motor-leading screw of 2 inside of turning, described being arranged at from the motor of 2 inside of turning can be controlled by external trigger, this triggering can be forms such as button, foot switch, acoustic control, after described motor is triggered, just can drives sickle head 3 and do reciprocating linear motion on 2 turning certainly automatically.Reciprocating transmission principle is shown in Fig. 6 (c), motor 22 is fixedly mounted in from turning on 2, the output shaft of leading screw 23 1 ends and motor 22 is fixedly linked, and the other end is installed in rotatably from turning on 22, and leading screw 23 just can rotate under the driving of motor 22 like this.Can be installed on the leading screw 23 by being arranged at its inner screw at the slide blocks 34 that the 2 inner sliding intracavity of turning certainly slide, like this, when leading screw 23 rotated under the driving of motor 22, slide block 34 just can reciprocatingly slide at 2 the sliding intracavity of turning certainly.The flexible end and the slide block 34 of described sickle head 3 are fixedly linked.
Described power generator can be bipolar electric energy, radio frequency, microwave, ultrasonic etc.The energy that power generator produces, this energy are passed to be installed on by lead I31 and lead II32 respectively operates pin on the bearing 3, in order to realize the operation of solidifying to tissue or organ.
The transmission principle that is used for the multivariant hemostasis sickle of hand-held under the mirror of chamber as shown in Figure 6.
Fig. 6 (a) shows the kind of drive of yaw motion, and promptly deflection driving wire 13 is connecting two deflecting wheels 93 up and down that are installed on the tool bar 1 by the race 931 that is arranged on the deflecting wheel 93; Like this when operating grip 8 under operation when moving, turn certainly and 2 just can under the effect of deflection driving wire 13, make corresponding motion.
Fig. 6 (b) shows the kind of drive of spinning motion, because rotation driving wire 14 is identical in the layout up and down of tool bar 1, therefore, only shows the arrangement of bottom among Fig. 6 (b).From turning 2 by being installed in rotatably on the interface on the swivel base 12 from adaptor 122.Rotation driving wire 14 turn certainly twine on 2 after, two ends are respectively through being fixed in two guide pads, 123 guiding on swivel base 12 after main directive wheel 10 and auxilliary directive wheel 11 are passed to the upper end of tool bar 1.Rotation driving wire 14 is arranged identical therewith in the upper end of tool bar 1.Like this, when operating grip 8 under the operation around be installed on tool bar 1 top from swivel base 12 rotation the time because the effect of rotation driving wire 14, turning certainly 2 just can rotate on swivel base 12.Fig. 7 shows when instrument deflects motion, is arranged at the situation of change of each driving wire in this instrument.Because the effect of guide pad 123, main directive wheel 10 and auxilliary directive wheel 11 makes instrument when deflecting motion, can ignore the length variations of rotation driving wire 14.Fig. 8 shows the motion conditions that this utility model is used for the hemostasis cutting tool of Minimally Invasive Surgery.
This utility model solidifies operating process such as Fig. 9, shown in Figure 10 in conjunction with power generator to tissue.Operative doctor is at first determined tissue 151 that will keep and the tissue 152 that will excise.In view of the above, operative doctor operation this utility model positions and each operation pin is inserted organization internal, at this moment, the power generator produce power, this energy is passed to by described interface and lead and respectively operates pin, realizes the operation of solidifying to tissue; Meanwhile, be provided with and motor excitation, make and respectively operate pin and move reciprocatingly along the direction of inserting tissue automatically, to strengthen the coagulation result of tissue from 2 inside of turning, Figure 9 shows that the reciprocating process that withdraws from, Figure 10 shows that the reciprocating process of thrusting.Constantly repeat the above-mentioned operating process of solidifying, just can form one organizationally and solidify zone 154; Change cutting class instrument and be positioned at described 153 pairs of tissues of line of cut that solidify the zone and cut, finally finish the tissue 152 that needs excision and need to keep and organize 151 lock out operation along illustrated.Because organizing of line of cut 153 regions solidified, therefore organizing in cutting process can be not hemorrhage again, and this is a considerable advantage of the present utility model, can save blood used in clinic to a great extent, and can reduce the complication that blood transfusion causes.It is pointed out that described operation pin of the present utility model can be provided with different quantity according to the actual requirements, as the operation pin that is installed on the sickle head 3 there are four.Described operation pin can also be according to different operation technique demands, and have different length.
It is worthy of note described operation pin along insert the organizer to reciprocating motion also can realize by operating grip 8 and assist handle 101 are carried out manual operation by the doctor, and do not adopt motor-driven mode.In addition, utilize principle of the present utility model, the operating side of instrument can not be the described pin of respectively operating, can also be integrated go out other and adopt the unredeemed multiple degrees of freedom Minimally Invasive Surgery of prior aries instrument, as terminal form can be scalpel, pliers, tweezers, operating scissors etc., and does not adopt described operation pin.
Below schematically this utility model and embodiment thereof are described, this description does not have restricted, and shown in the accompanying drawing also is one of embodiment of the present utility model, and practical structure is not limited thereto.So; if those skilled in the art is enlightened by it; under the situation that does not break away from this utility model creation aim; the transmission, driving device and the connected mode that adopt other form all should belong to protection domain of the present utility model without creationary design frame mode and the embodiment similar to this technical scheme.
