Abstract
Description
A tumor biopsy sampling device for medical clinical use Technical Field
[0001] The present invention relates to the technical field of clinical medicine, in particular to a tumor biopsy sampling device for clinical medicine. Background Art
[0002] Definitive diagnosis of tumors is made by detecting tumor cells in tumor tissue. Various types of tumors can form in the same area of the body, so cell examination is necessary to identify the type of tumor before treatment. Tissue biopsy methods used for tumor lesions include incisional biopsy, which involves making an incision in the skin and sampling the tissue, fine needle aspiration biopsy using a syringe, and gun biopsy, which uses a needle-firing device.
[0003] Traditional puncture biopsy sampling generally requires puncture to establish a sampling channel, and then use a sampling device to perform sampling after the puncture is completed. The puncture device and the sampling device are two single devices. Therefore, inventors in this field have proposed a tumor biopsy sampling device for medical clinical use to solve the above problems.
[0004] Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the present invention provides a tumor biopsy sampling device for medical clinical use, which solves the problem that two different devices, namely a puncture device and a sampling device, are required in biopsy sampling.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A tumor biopsy sampling device for medical clinical use includes a main body, the front end of the main body is fixedly connected to a sampling tube, the outside of the sampling tube is provided with a positioning mechanism, the interior of the main body is slidably connected to a driving plate, the left and right ends of the driving plate are fixedly connected to pull rings, the front end of the driving plate is fixedly connected to a clamping block, two clamping rings are provided inside the main body, the opposite ends of the two clamping rings are fixedly connected to a pressing plate, the opposite ends of the two clamping rings are fixedly connected to a spring a, the ends of the two springs a away from the clamping rings are fixedly connected to the inner wall of the main body, the front end of the driving plate is provided with a spring b, the middle part of the driving plate is threadedly connected to a puncture tube, the front end of the puncture tube is fixedly connected to a puncture needle, the front side of the puncture tube is provided with a sampling groove, and the interior of the puncture tube is slidably connected to a closing rod.
[0007] Preferably, the positioning mechanism includes a positioning ring, the outside of the positioning ring is fixedly connected to a strap, the outside of the positioning ring is fixedly connected to six spherical knots a, the six spherical knots a are fixedly connected to a sleeve at one end away from the positioning ring, the rear sides of the six sleeves are threadedly connected to a locking nut, the insides of the six sleeves are slidably connected to a sliding rod, the six sliding rods are fixedly connected to a spherical knot b at one end away from the sleeve, and every three spherical knots b are fixedly connected to a sliding ring at one end away from the sliding rod.
[0008] Preferably, the clamping block is engaged with two clamping rings, and the two pull rings and the pressing plate are all arranged outside the main body.
[0009] Preferably, the two clamping rings slide relatively inside the main body, and the two clamping rings pass through the left and right sides of the main body respectively.
[0010] Preferably, the rear end of the sealing rod is threadedly connected to the rear end of the puncture tube, and the puncture needle is arranged on the front side of the sampling tube.
[0011] Preferably, the inner diameter of the sampling tube is equal to the diameter of the puncture tube, and the sampling tube and the puncture tube are provided in various models.
[0012] Preferably, the bandage is mounted on the outside of the human body, and the two slip rings slide on the outside of the sampling tube.
[0013] Preferably, the sleeve and the slide rod are provided in two types and are staggeredly arranged on the rear side of the positioning ring.
[0014] Working principle: When in use, first fix the positioning ring to the outside of the human body with a strap, align the positioning ring with the sampling area, then pass the sampling tube through the two slip rings, loosen the locking nut, and adjust the angle of the sampling tube to drive the slip ring to rotate, which in turn drives the slide rod to slide inside the sleeve. When the angle calibration of the sampling tube is completed, tighten the locking nut to complete the positioning work; then use the puncture needle to pierce the human body with the spherical knot b and the internal device, close to the tumor, and adjust the puncture degree of the puncture tube according to the size of the tumor. This can be completed by rotating the puncture tube. After the distance adjustment is completed, pull the pull ring to drive the driving plate and then drive the puncture tube to pierce the tumor through the puncture needle. At this time, the driving plate squeezes the spring b and drives the clamping block to engage with the clamping ring. After the engagement is completed, rotate the closing rod to remove the closing rod from the inside of the puncture tube, then press the pressing plate to release the clamping ring and the clamping block, and then push the driving plate through the rebound force of the spring b to drive the puncture tube to move quickly, thereby completing the sampling work through the sampling slot. After the sampling is completed, the sampling tube can be removed from the human body.
[0015] The present invention provides a tumor biopsy sampling device for clinical medical use. It has the following beneficial effects:
[0016] 1. The present invention establishes a sampling channel by inserting a sampling tube into the human body, and drives the clamping block to engage with the clamping ring by squeezing the spring b through the driving plate, and at the same time drives the puncture needle to pierce the sampling tissue. Then, the closing rod is removed, and the pressing plate is pressed to release the clamping ring and the clamping block. Then, the rebound force of the spring b pushes the driving plate to drive the puncture tube to move quickly, and then the sampling work is completed through the sampling slot.
[0017] 2. The present invention realizes the functional superposition of the traditional puncture device and the sampling device through structures such as the sampling tube, the puncture tube, and the sealing rod, so that one device can directly perform sampling work. The device structure is simple and the practicality of the device is improved.
[0018] 3. The present invention fixes the positioning ring on the outside of the human body through a strap, and adjusts the orientation of the two slip rings by sliding the sliding rod inside the sleeve. The sampling tube slides in the middle of the two slip rings, and then the slip ring makes the sampling tube more stable during the movement, thereby reducing the risk during the sampling process.
