Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
as shown in fig. 1 to 7, an operating lamp for cardiac surgery comprises an annular bracket 1 and a bracket member 2, wherein the bracket member 2 and the annular bracket 1 can be in rotary fit or fixed fit, a locking assembly is arranged in the bracket member 2, a sliding block assembly matched with the locking assembly is assembled on the bracket member 2, the sliding block assembly is connected with a positioning plate 4 through a first connecting piece 31, the positioning plate 4 is provided with a positioning assembly, the positioning assembly comprises two linked laser heads 51, the two laser heads 51 are rotatably and correspondingly arranged at two ends of the positioning plate 4, and the positioning plate 4 is connected with a shadowless lamp panel 6 through a second connecting piece 32; the first connecting piece 31 is provided with a control piece, and the sliding block assembly can move along the length direction of the bracket piece 2 when the bracket piece 2 is fixedly matched with the annular bracket 1 through control.
The control piece is an expansion board 7 which is rotationally connected with the first connecting piece 31, the locking component comprises a base plate 21 which is arranged across the bracket piece 2, sliding blocks 22 are respectively arranged on two sides of the base plate 21, tension springs 23 are arranged between the sliding blocks 22 on two sides, sliding grooves 2a are respectively arranged on two sides of the bracket piece 2, abutting boards 24 which are matched with the expansion board 7 are respectively arranged on the lower parts of the sliding blocks 22, and protruding blocks 22a are respectively arranged on the sliding blocks 22; the locking assembly comprises a pair of locking rods 25 arranged along the length direction of the bracket member 2, wedge-shaped blocks 25a matched with the convex blocks 22a on the sliding blocks 22 are arranged at the end parts of the locking rods 25, and pressure springs 26 are respectively arranged between the wedge-shaped blocks 25a and the bracket member 2.
The locking rods 25 are respectively provided with an avoidance groove 25b, and the wedge-shaped blocks 25a are arranged in the avoidance grooves 25b of the other locking rods 25. By such design, the structure is more compact when the avoiding groove 25b is utilized, so that the volume of the bracket member 2 is smaller.
The number of the expansion plates 7 is two, and the two expansion plates 7 are arranged on two sides of the first connecting piece 31 through rotating shafts. The coaxially arranged spreader plates 7 can synchronously rotate to disperse stress and reduce the stress of the single spreader plate 7, thereby prolonging the service life of the spreader plate.
The spreader plate 7 is connected with a handle 71. The handle 71 is arranged to facilitate the rotation of the spreader plate 7, so that the force application and the operation are more convenient.
The lower end of the abutment plate 24 extends outwardly to form a stop bar 24a. Since the spreader plate 7 only needs to be rotated to the horizontal position at most, the spreader plate 7 does not need to be rotated by 360 °, and the rotation angle of the handle 71 is limited by the limit bars 24a at both sides, so that the operation efficiency can be improved.
The positioning assembly further comprises a rotating disc 52 which is rotationally connected with the positioning plate 4, two ends of the rotating disc 52, which are positioned at the same diameter, are respectively connected with a linkage piece 53, and the other end of the linkage piece 53 is connected with the laser head 51.
Working principle of laser heads 51 at two ends of locating plate 4 are linked: when one end of the laser head 51 is rotated, the laser head 51 drives the rotating disc 52 to rotate through the corresponding side linkage piece 53, the rotating disc 52 rotates to drive the other side linkage piece 53 to move, and the other side linkage piece 53 drives the other end of the laser head 51 to rotate, so that linkage of the laser heads 51 at two ends is realized.
The second connecting piece 32 on articulated have and lean on the pole 81, the lower extreme of second connecting piece 32 be connected with dwang 33, dwang 33 with be provided with telescopic link 82 between the back of shadowless lamp panel 6, the lower extreme of dwang 33 be provided with bulb 33a, the center of shadowless lamp panel 6 with bulb 33a be connected.
The second connecting piece 32 is connected with a limiting piece 34 with a notch 34a, and the abutting rod 81 can pass through the notch 34 a.
Because the working principle of the shadowless lamp is to use a plurality of light sources to fade the shadow, the shadow is not obvious, and the shadow (mainly the shadow of the operating hands of the surgical instruments and medical staff) still exists when the shadowless lamp irradiates. This pale shadow can interfere with the physician's judgment of the location of the procedure during the procedure. In the operation process, the supporting rod 81 can be pulled down to pass through the notch 34a, so that the lower end of the supporting rod 81 supports against the back surface of the shadowless lamp panel 6, the shadowless lamp panel 6 is in an inclined state, then the shadowless lamp panel 6 rotates in the inclined state with the center of the ball head 33a, along with the rotation of the shadowless lamp panel 6, the irradiation angle changes, the light shadow changes due to the different irradiation angles, and the shadow and the heart valve (entity) are distinguished, so that the doctor is assisted to judge the operation position better.
The center of the bracket member 2 is connected with a wire tube 9 for embedding wires, and a supporting rod 91 is arranged between the wire tube 9 and the annular bracket 1. The arrangement of the wire pipe 9 can facilitate wiring, so that the wiring is tidier and convenient to maintain.
Working principle:
When the spreader plate 7 does not spread the sliding blocks 22 on both sides, that is, when the spreader plate 7 is not in a horizontal state, the sliding blocks 22 on both sides are retracted inwards under the action of the tension springs 23, the protruding blocks 22a on the sliding blocks 22 are abutted against the inclined surfaces of the wedge-shaped blocks 25a and act on the wedge-shaped blocks 25a, so that the locking rod 25 is retracted inwards against the elastic force of the compression springs 26 (the compression springs 26 are further compressed), the locking rod 25 is separated from the inner wall of the annular support 1, and at this time, the support member 2 can rotate on the annular support 1 to adjust the position of the support member 2.
In the bypass operation process, the support member 2 is rotated to the bypass direction, the opening plate 7 is rotated through the handle 71, so that the opening plate 7 is propped against the propping plate 24 on the sliding block 22, and the opening plate 7 is continuously rotated to prop the propping plate 24 to two sides, so that the sliding block 22 moves to two sides against the tension of the tension spring 23 until the opening plate 7 is in a horizontal state. As the slider 22 moves toward both ends of the base plate 21, the projection 22a of the slider 22 is separated from the wedge-shaped block 25a, the lock lever 25 is extended outward by the pressure of the compression spring 26, and the outer end of the lock lever 25 abuts against the ring-shaped bracket 1, so that the bracket member 2 is fixed to the ring-shaped bracket 1, and at this time, the bracket member 2 and the ring-shaped bracket 1 cannot rotate relatively. Meanwhile, after the sliding block 22 moves to both sides, the protrusion 22a enters the sliding groove 2a of the bracket member 2, and at this time, the slider assembly can slide along the length direction of the bracket member 2. Because the bracket piece 2 can not rotate at this time, and the sliding block component can slide along the length direction of the bracket piece 2, the shadowless lamp panel 6 can only move along the bridging direction at this time, so as to meet the requirement of moving and adjusting the shadowless lamp along the bridging direction in the heart bridging operation.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting. The objects of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the examples and embodiments of the invention may be modified or practiced without departing from the principles described.
