Description

Technical Field

[0001] The utility model relates to the field of kidney disease dialysis, in particular to a biopsy puncture device. Background Art

[0002] Puncture biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. Because limb-sparing treatment of malignant tumors has become a major trend, stricter requirements are placed on the sampling route and method during biopsy. Improper biopsy often causes the tumor to contaminate important local structures such as blood vessels and nerve bundles during sampling, making it impossible to completely remove the tumor and leading to failure of limb-sparing treatment. Therefore, before puncture biopsy, one should have a full understanding of the nature, staging and treatment of the tumor, conduct adequate preoperative planning, and ensure that the needle channel for sampling is located on the surgical incision so that it can be completely removed during surgery.

[0003] However, in the prior art, since medical staff need to hold the puncture needle for a long time during the puncture of the patient, the biopsy puncture is greatly affected by human factors. For example, factors such as hand shaking of medical staff and interference from other medical staff will affect the accuracy of the puncture. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a biopsy puncture device.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows: a biopsy puncture device comprises a fixing seat, the upper end of the fixing seat is fixedly connected with a connecting block, the right side of the connecting block is fixedly connected with a fixing frame, an electric push rod is arranged inside the fixing frame, the lower end of the electric push rod is fixedly connected with a slide plate, both sides of the slide plate are fixedly connected with guide blocks, the inner wall of the fixing frame is provided with a guide groove, the front edge position of the fixing frame is fixedly connected with a scale block, the lower end of the fixing frame is fixedly connected with a connecting wire, the other end of the connecting wire is fixedly connected with a positioning ring, and suction cups are arranged on both sides of the positioning ring;

[0006] A connecting plate is fixedly connected to the upper edge of the slide plate, a threaded hole is provided inside the connecting plate, a sliding hole is provided inside the connecting plate near the threaded hole, a bolt is movably connected inside the connecting plate, a clamping ring is fixedly connected to the right side of the bolt, a clamping ring is sleeved on the outside of the clamping ring, a fixing clip is fixedly connected to the right side of the clamping ring, a short plate is fixedly connected to the lower end of the clamping ring, a stabilizing rod is fixedly connected to the left side of the short plate, and a piercer is arranged inside the slide plate.

[0007] Preferably, the suction cups are provided in two groups and are symmetrically arranged about the center line of the positioning ring.

[0008] Preferably, the guide block slides in the guide groove through an electric push rod and a slide plate.

[0009] Preferably, the fixing clamp is movably connected to the bolt through a clamping ring and a clamping ring.

[0010] Preferably, the stabilizing rod slides in the sliding hole through a clamping ring, a clamping ring, a bolt, a connecting plate and a threaded hole inside the connecting plate.

[0011] By adopting the above technical scheme, by turning on the electric push rod, the electric push rod pushes the slide plate to move, so that the puncture needle at one end of the puncture device enters the patient's affected part for extraction. At the same time, when the slide plate is sliding, the guide block on one side thereof slides inside the guide groove. With the cooperation of the guide block and the guide groove, the stability of the slide plate and the puncture device during movement can be increased. When sliding, the guide block will correspond to the scale block, so as to realize the control of the entry length of the puncture needle, and the positioning ring can be fixed to the outside of the patient's skin by a suction cup to provide an accurate position for puncture. The puncture device can puncture the patient's affected part through the electric push rod, the slide plate, the guide block, the scale block, and the positioning ring. The electric push rod is used to push the puncture instead of the medical staff's hand-held puncture, which greatly increases the accuracy of the puncture.

[0012] By adopting the above technical solution, by rotating the bolt, under the action of the threaded hole inside the connecting plate, the bolt pushes the clamping ring and the clamping ring to one side, so that the fixing clamp is close to the left and right sides of the puncture device, thereby fixing the puncture device. While the fixing clamp moves, the stabilizing rod slides in the sliding hole. Under the action of the stabilizing rod and the sliding hole, the fixing clamp can be prevented from shifting during movement, affecting the fixing effect of the puncture device. The position of the fixing clamp can be adjusted by the bolt, the clamping ring, the clamping ring, the connecting plate and the threaded hole inside the connecting plate, so that it can be close to both sides of the puncture device, increasing the stability between the puncture device and the slide board, and at the same time, it can also prevent the puncture device from shaking and affecting its use.

[0024] Specifically, the bolt 15 is rotated, and under the action of the internal threaded hole 13 of the connecting plate 12, the bolt 15 pushes the clamping ring 16 and the clamping ring 17 to move to one side, so that the fixing clip 18 is close to the left and right sides of the puncture device 21, thereby fixing the puncture device 21. While the fixing clip 18 moves, the stabilizing rod 20 slides in the sliding hole 14. Under the action of the stabilizing rod 20 and the sliding hole 14, the fixing clip 18 can be prevented from deviating during movement, which affects the fixing effect of the puncture device 21. The position of the fixing clip 18 can be adjusted by the bolt 15, the clamping ring 16, and the clamping ring 17 in cooperation with the connecting plate 12 and the threaded hole 13 inside thereof, so that it can be close to the two sides of the puncture device 21, thereby increasing the stability between the puncture device 21 and the slide plate 5, and at the same time, it can also prevent the puncture device 21 from shaking, which affects its use.

[0025] Working principle: When the biopsy puncture device is in use, first, the puncture device 21 is fixed inside the slide plate 5. The specific operation is that by rotating the bolt 15, under the action of the internal threaded hole 13 of the connecting plate 12, the bolt 15 pushes the clamping ring 16 and the clamping ring 17 to move to one side, so that the fixing clamp 18 is close to the left and right sides of the puncture device 21, and the puncture device 21 is fixed. While the fixing clamp 18 moves, the stabilizing rod 20 slides in the sliding hole 14. Under the action of the stabilizing rod 20 and the sliding hole 14, the fixing clamp 18 can be prevented from deviating during movement, which affects the fixing effect of the puncture device 21. The position of the fixing clamp 18 can be adjusted by the bolt 15, the clamping ring 16, and the clamping ring 17 in conjunction with the connecting plate 12 and the internal threaded hole 13, so that it can be close to the two sides of the puncture device 21, thereby increasing the stability between the puncture device 21 and the slide plate 5, and also avoiding puncture. The device 21 shakes, affecting its use. After the fixation is completed, the positioning ring 10 is fixed to the patient's skin by the suction cup 11 to provide a correct position for the puncture device 21. Then, the electric push rod 4 is turned on, and the electric push rod 4 pushes the slide plate 5 to move, so that the puncture needle at one end of the puncture device 21 enters the patient's affected part for extraction. At the same time, during the sliding process of the slide plate 5, the guide block 6 on one side slides inside the guide groove 7. With the cooperation of the guide block 6 and the guide groove 7, the stability of the slide plate 5 and the puncture device 21 during movement can be increased. The guide block 6 will correspond to the scale block 8 when sliding, so as to control the entry length of the puncture needle. The puncture device 21 can puncture the patient's affected part through the electric push rod 4, the slide plate 5, the guide block 6, the scale block 8, and the positioning ring 10.
