Ball cup is fixedly linked integral with the side (face) of base, elbow arm respectively; Bulb is connected as a body with the two ends of shoulder arm respectively; In the through hole of the spherical plain bearing rod end of arm, insert peritoneoscope, the body of rod of this mirror is just in time by admittedly in the hole of spherical plain bearing rod end; Realize arm with this and to be laparoscopicallyly fixedly linked; Peritoneoscope for fulcrum, can make any change at omnibearing Plane Rotation and angle of inclination with unsettled arm by spherical plain bearing rod end;
During use, first close the switch of electromagnetic lock, make electromagnetic lock lose locking function (unblock), need according to the position of patient the angle of inclination adjusting bulb assembly; According to the needs adjustment shoulder arm of height or the flexible length of elbow arm; Open the switch of electromagnetic lock after mixing up angle, make bulb assembly be in locking state (adjusting) on a large scale, determine patient body position and laparoscopically relative position region with this; The adjustment by a small margin (adjusting among a small circle) of the laparoscopically camera lens depth in operation, assistant can by taking out in the through hole of spherical plain bearing rod end, insert peritoneoscope and come; Very convenient and practical.
The technique effect that the application is useful is: simple and practical, decreases the labor intensity of assistant to a certain extent, improves surgical quality and the speed of doctor, is one of armarium that people are desirable.

Detailed description of the invention
As shown in Figure 1, the object of the application to provide a kind of ceiling mounting type lens bracket, solve the problem with this, the structure of this support is by electromagnetic lock 1, base 2, shoulder arm 3, elbow arm 4, the bionical scholar's of arm 5(arm) be equivalent to joint by bulb assembly 6() be connected to form; Mounted ceiling mounting type lens bracket is suspended on the top of operating-table 17;
Base 2 is one piece of circular plate body, and base 2 is provided with several nail, and base 2 is fixed on the top board of the ceiling 7(operating room above operating-table by nail setscrew) on; Shoulder arm 3, elbow arm 4, the two makes with gas strut; The problem of flexible length can be solved with this; The gas strut arbitrarily stopping formula selected by the gas strut of shoulder arm 3, elbow arm 4; Adjust flexibly with this and locate the Len req of gas strut;
Arm 5 is connected to form by screw rod 9 and spherical plain bearing rod end 8, is provided with one section of screwed pipe 9 at the external part of the gas strut of elbow arm 4, and the screw rod of spherical plain bearing rod end 8 can be screwed in screwed pipe 9, adjusts the length distance of the two with this; The screw rod of spherical plain bearing rod end 8 is provided with standby jack panel 10, with the relative position of this fastening screwed pipe 9 with described screw rod;
Be connected as a body by bulb assembly 6 between base 2, shoulder arm 3, elbow arm 4; Bulb assembly 6 comprises ball cup 11 and bulb 12 two parts; Ball cup 11 is by the housing fixed and moveable head plate 13(plug) form, housing and the head plate 13 of ball cup 11 are connected as a body by helicitic texture; Screw thread is arranged on the case inside of ball cup 11, and head plate 13 is equivalent to one section of bolt; The ball cup 11 installing bulb 12 is undertaken adjusting the compression to bulb 12 and degree of relaxation (gap adjustment) by the screw thread rotating head plate 13; The housing of ball cup 11 is with magnetic conduction, electric insulant are not made, as engineering plastics; Bulb 12 steel car system forms; The head plate 13 of ball cup 11 is made with stalloy; The contact surface of head plate 13 and bulb 12 matches in shape, guarantees the fastness of magnetic with this; The head plate 13 of ball cup 11 is connected with the circuit of electromagnetic lock 1, and the circuit 14 of electromagnetic lock 1 adopts soft circuit to make; In circuit 14, there is one section of circuit coiled (not drawing in figure), lay in the spare length of electric wire with this; The lock body of electromagnetic lock 1 is fixed on ball cup 11, when the head plate 13 that the electric current of electromagnetic lock 1 is made by stalloy, head plate 13 can produce powerful electromagnetic attraction and tightly hold bulb 12; (brake) positioning action is played with this; The head plate 13 of all bulb assemblies 6 is controlled by the circuit 14 of a set of electromagnetic lock 1; The switch 15 of the circuit 14 of electromagnetic lock 1 adopts hand switch, and switch 15 is arranged on arm 5, facilitates the operant activity of assistant with this;
Ball cup 11 is fixedly linked integral with the side (face) of base 2, elbow arm 4 respectively; Bulb 12 is connected as a body with the two ends of shoulder arm 3 respectively; In the through hole of the spherical plain bearing rod end 8 of arm 5, insert peritoneoscope 16, the body of rod of peritoneoscope 16 is just in time by admittedly in the hole of spherical plain bearing rod end 8; Being fixedly linked of arm 5 and peritoneoscope 16 is realized with this; Peritoneoscope 16 for fulcrum, can make any change at omnibearing Plane Rotation and angle of inclination with unsettled arm 5 by spherical plain bearing rod end 8;
During use, first close the switch 15 of electromagnetic lock 1, make electromagnetic lock 1 lose locking function (unblock), need according to the position of patient the angle of inclination adjusting bulb assembly 6; According to the needs adjustment shoulder arm 3 of height or the flexible length of elbow arm 4; Open the switch 15 of electromagnetic lock 1 after mixing up angle, make bulb assembly 6 be in locking state (adjusting) on a large scale, determine the relative position region of patient body position and peritoneoscope 16 with this; The adjustment by a small margin (adjusting among a small circle) of the camera lens depth of peritoneoscope 16 in operation, assistant can by taking out in the through hole of spherical plain bearing rod end 8, insert peritoneoscope 16 and come; Very convenient and practical.
The technique effect that the application is useful is: simple and practical, decreases the labor intensity of assistant to a certain extent, improves surgical quality and the speed of doctor, is one of armarium that people are desirable.
