Fig. 2 is a schematic side view of the sampling device of fig. 1.
Detailed Description
The present invention will be described in detail with reference to fig. 1 and 2, and the exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The utility model provides a peritoneoscope is looked directly down and is got tissue biopsy device, it includes puncture needle 1 of puncture stomach wall, is equipped with two passageways 11 along its length direction in this pjncture needle, and peritoneoscope optics visual tube can be placed to one of them passageway, and sampling device 2 can be placed to another passageway, and this sampling device is in the sample is taken a sample to the biopsy tissue under the direct vision of optics visual tube, has realized visual sample to greatly improve the security and the success rate of operation, simplified operation flow, reduced patient's misery. As a preferable mode, the sampling device can directly adopt laparoscopic forceps or scissors, and not only is convenient to operate, but also is low in cost.
As another preferred mode, as shown in fig. 1, the sampling device 2 of the present invention comprises a sampling scissors 21 and a sampling head 22 connected to the sampling scissors, the sampling scissors drives the sampling head to extend out or retract into the other channel, after the sampling scissors extend out of the other channel to cut off the biopsy tissue, the sampling head and the sampling scissors can clamp and retract the biopsy tissue into the other channel. Therefore, under the illumination of the laparoscope optical sight tube in one channel, the visual sampling operation is realized, the biopsy tissue can be conveniently and quickly taken out, the sampling success rate is improved, and the operation risk is reduced.
Specifically, the sampling scissors 21 includes two scissors arms 211 arranged in a cross manner, one end of each of the two scissors arms is provided with a handle 212, the other end of each of the two scissors arms is provided with a cutter head 213, the two scissors arms are rotatably connected through a pin 214 arranged at the cross point, and the two handles drive the two cutter heads to rotate around the pin in opposite directions so as to cut off the biopsy tissue. The sampling scissors have simple structure and convenient operation; and the sampling head is fixedly arranged on the pin shaft of the sampling scissors, when the sampling scissors cut off the biopsy tissue, the sampling head can clamp the cut biopsy tissue between the sampling head and the tool bit, and then the whole sampling scissors and the sampling head are pulled by the handle to retract into the other channel, so that the visual taking-out of the biopsy tissue is ensured.
Preferably, the sampling head is spoon-shaped, so that the sheared biopsy tissue can be conveniently supported and prevented from falling off; specifically, the sampling head 22 includes a spoon handle 221 and a spoon head 222, one end of the spoon handle is fixedly connected with the pin shaft, and the other end of the spoon handle is fixedly connected with the spoon head, so that the whole sampling head can be guaranteed to move along with the sampling scissors. In the implementation process, the length of the sampling head is longer than that of the cutter head, namely the cutter head can be accommodated in the spoon head, so that the volume of the whole device can be reduced on one hand, and the operation is convenient; on the other hand, the cut biopsy tissue can be ensured to be stably clamped. The spoon handle and the spoon head of the utility model are of an integrated structure, the spoon handle and the spoon head can be guaranteed to be firm in structure, and the processing and forming are simple. The sampling head is made of elastic materials, when the tissue is cut by the cutter head of the sampling scissors, the sampling head made of the elastic materials can avoid part of the tissue under the action of elasticity, so that enough clamping space can be ensured, the interference to the work of the cutter head can be reduced, and the tissue damage can be reduced.
