Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
The puncture supporter 1 that Fig. 1 shows this utility model one embodiment is installed on the structural representation on ultrasonic probe 2.As shown in Figure 1, puncture supporter 1 comprises fixture 11 and puncture needle guiding device 12.Puncture supporter 1 is mounted on ultrasonic probe 2 by fixture 11.Puncture needle guiding device 12 is arranged in fixture 11, for providing the puncture guide hole 31 (shown in Figure 3) of biopsy needle guide 3.
Puncture needle guiding device 12 comprises the first needle stand 13 and the second needle stand 14.First needle stand 13 is installed in fixture 11, first needle stand 13 offers V-arrangement puncture tank 131, and this V-arrangement puncture tank 131 is from first end (the i.e. puncture arrival end 311 of the first needle stand 13, shown in Figure 2) extend through the second end (namely puncture the port of export 312, shown in Figure 2) to the first needle stand 13 always.Second needle stand 14 is rotatably installed on the first needle stand 13 with spring-loaded manner.In concrete example, the first needle stand 13 and the second needle stand 14 can realize being connected rotationally with spring-loaded manner by existing various suitable mode the cooperation of torsion spring (the such as rotating shaft with), just repeat no more at this.Relative first needle stand 13 of second needle stand 14 extends a clamping part 142, and the bottom of this clamping part 142 is provided with the arcwall face 141 coordinated with V-arrangement puncture tank 131, and this arcwall face 141 can portion envelops puncture needle 3 (shown in Figure 4).Similarly, this arcwall face 141 extends through the second end (namely puncture the port of export 312, shown in Figure 2) to the second needle stand 14 from the corresponding first end of the second needle stand 14 (namely puncture arrival end 311, shown in Figure 2) always.This spring-loaded manner impels the arcwall face 141 of the second needle stand 14 to produce the movement tendency stretching into the V-arrangement puncture tank 131 of the first needle stand 13, makes arcwall face 141 and V-arrangement puncture tank 131 jointly form the puncture guide hole 31 (shown in Figure 3) of biopsy needle guide 3.
Fig. 2 shows the schematic diagram of puncture needle inserting needle and guiding.As shown in Figure 2, because V-arrangement puncture tank 131 and arcwall face 141 extend through the puncture port of export 312 from puncture arrival end 311 always, centre is not split, and enables puncture needle 3 against V-arrangement puncture tank 131 completely when inserting needle or arcwall face 141 is advanced, and does not have other to stop and interferes.Further as shown in Figure 2, at puncture arrival end 311 place, the first end of the second needle stand 14 is relative to first end indentation one segment distance of the first needle stand 13, simultaneously, arcwall face 141 forms an inserting needle inclined-plane 147 at the first end place (namely puncture arrival end 311 place) of the second needle stand, puncture needle 3 first can be ridden on V-arrangement puncture tank 131 before preparation enters puncture guide hole 31, then have inserting needle inclined-plane 147 when pushing ahead as guiding, facilitate inserting needle.
Further as shown in Figure 3 and Figure 4, the V-arrangement puncture tank 131 of the first needle stand 13 has the first surface 1311 and second surface 1312 that form V-arrangement.The first surface 1311 of V-arrangement puncture tank 131 extends upward the first restriction face 1313, and the second surface 1312 of V-arrangement puncture tank 131 extends upward the second restriction face 1314.Similarly, the two sides of arcwall face 141 both sides of the second needle stand 14 corresponding clamping part 142 respectively extend upward the first secondary surface 143 and the second secondary surface 144.When the arcwall face 141 of the second needle stand 14 to coordinate with the V-arrangement puncture tank 131 of the first needle stand 13 clamp puncture needle 3 time, gap 313 is formed between first restriction face 1313 and the first secondary surface 143, gap 314 is formed between second restriction face 1314 and the second secondary surface 144, gap 313 and 314 is all less than the diameter of current clamped puncture needle 3, in order to avoid puncture needle 3 is from wherein coming off.
Again as shown in Figure 3-Figure 5, the second needle stand 14 is also provided with operating side 145.Pressing operation end 145, just the second needle stand 14 can be made fully to overcome the elastic force of spring-loaded manner and rotate relative to the first needle stand 13, thus make arcwall face 141 leave V-arrangement puncture tank 131 to open puncture guide hole 31, just puncture needle 3 therefrom can be removed subsequently and realize being separated release (shown in Figure 5).
In addition, puncture needle guiding device 12 is also provided with adjustment structure 146, and this adjustment structure 146 makes arcwall face 141 leave the active force of V-arrangement puncture tank 131 for applying certain elastic force overcoming spring-loaded manner relative to the first needle stand 13 to the second needle stand 14.In specific embodiment, this adjustment structure can be adjustment screw 146, is threaded with the second needle stand 14.And, the end of adjustment screw 146 can rotate to and contacts with the active force applied to the second needle stand 14 upwards with the supporting surface of the first needle stand 13, thus regulate the distance between arcwall face 141 and V-arrangement puncture tank 131, to form the puncture guide hole 31 of different size, support that the puncture needle 3 of different size carries out puncturing operation.When carrying out the size adjustment of puncture guide hole 31, gap 313 and gap 314 need be less than the diameter of current clamped puncture needle 3 all the time, and puncture needle 3 in adjustment process can not be thrown off from V-arrangement puncture tank 131.
Puncture supporter of the present utility model can facilitate the inserting needle of puncture needle to operate by above-mentioned puncture needle guiding device and realize stable guiding, puncture needle and puncture supporter sharp separation is facilitated to discharge, scalable puncture guide hole size is to adapt to the puncture needle of different size again, and succinct structure is more convenient cleaning and sterilization also.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
