Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a urinary system tumor adjacent to cancer sampling device. Background Technology

[0002] Urothelial carcinoma (including bladder cancer, renal pelvis cancer, and ureter cancer) is a common tumor of the urinary system; renal pelvis cancer refers to malignant tumors of the urothelial tract that occur in the epithelial tissue of the renal pelvis or calyces. Long-term use of analgesics, chronic inflammation or stone irritation, and exposure to carcinogenic chemicals are often predisposing factors for renal pelvis cancer in patients with interstitial nephritis. The principle of treatment for renal pelvis cancer is radical resection. For solitary, low-stage, and low-grade tumors, organ-sparing surgery is used. Surgical resection is the main treatment for renal pelvis cancer. For patients without distant metastasis, the standard surgical procedure is routine radical surgery, performed through two incisions, with resection including the kidney, renal fat capsule, the entire ureter, and bladder cuff resection. For smaller, solitary, low-grade, superficial renal pelvis tumors, organ-sparing surgery is performed when percutaneous nephrolithotomy carries risks of bleeding, tumor extravasation, or implantation. Organ-sparing surgery includes transurethral ureteroscopic pyelonephroscopy or percutaneous nephrolithotomy. Nephroscopic electrocautery or resection: Ureteroscopic treatment of renal pelvic tumors is suitable for low-stage, single, superficial tumors. It involves minimal surgical trauma and rapid patient recovery, and percutaneous nephrolithotomy provides ample endoscopic space. Organ-sparing surgeries also include open tumor resection: for low-stage, low-grade, locally superficial unilateral or bilateral renal pelvic tumors, organ-sparing open surgeries are used, such as local simple tumor resection or pyelolithotomy with electrocautery. If the tumor does not involve the renal parenchyma, partial nephrectomy can be performed. Organ-sparing resections require complete removal of the cancerous lesion to minimize recurrence, improve postoperative outcomes, and extend survival time. Tumor surgery involves extensive resection around the tumor to ensure complete removal. The surgical margin is the edge of the excised tumor tissue. After resection, the surgical margin is examined and sent to the pathology department for examination to check for cancer cells. The presence of cancer cells at the surgical margin indicates a positive surgical margin, suggesting residual tumor and incomplete removal.

[0003] In summary, the current process of sampling adjacent to urinary system tumors presents the following technical problems: Firstly, in organ-preserving surgeries, the edge of the tumor tissue is surgically removed, but due to the structure of the kidney tissue, bleeding may occur after sampling. Hemostasis at the sampling site is necessary, usually through electrocautery. This requires removing the sampling device, applying negative pressure to aspirate the bleeding, and then performing hemostasis again, involving numerous steps. Secondly, the side adjacent to the cancer needs to be marked on the sampled tissue. In the current testing process, because the sampled tissue lacks a specific shape, the test results are often false negatives due to the tissue being far from the cancerous side. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention provides a urinary system tumor adjacent to cancer sampling device.

[0008] Furthermore, a limiting groove is provided on the lower side of the air plug to cooperate with the upper rod limiting groove, and the upper rod is slidably connected in the limiting groove; The drive assembly includes a middle gear, a drive gear, and a motor. The motor is fixedly connected to the ring seat, and the drive gear is provided on the upper side of the motor.

[0009] Furthermore, the gas regulating assembly includes an inflation tube, a negative pressure tube, a connecting frame, a base, an air cylinder, a rack, a connecting rod, a sliding ring, a compression spring, a fixing ring, a connecting column, a piston, a trigger rod, and a slide rod. The connecting frame is fixedly connected to one side of the upper seat, and the base is fixedly connected to the connecting frame away from the upper seat. Two air cylinders are fixedly connected to the base, and the two air cylinders are arranged opposite to each other. One end of the inflation tube is fixedly connected to one of the air cylinders. The inflation tube passes through the ring seat, the main cylinder, the heat insulation ring, the heating ring, the outer half-ring frame, and the insertion end. The other end of the inflation tube protrudes from the insertion end near the heat-conducting plate. The air plug has a central air hole, and a negative pressure tube is fixedly connected to the air plug at the central air hole position. The negative pressure tube is fixedly connected to another air cylinder. A rack is provided on one side of the middle gear, and the rack meshes with the middle gear. The rack is parallel to the axis of the two air cylinders. A connecting column is provided between the two air cylinders. A piston is fixedly connected to both ends of the connecting column. The piston is slidably connected in the corresponding air cylinder. A sliding ring is slidably connected to the connecting rod.

[0010] Furthermore, the hemostasis marking part includes an energy storage element, a control key, and a wire. The energy storage element is fixedly connected to the ring seat, the energy storage element is provided with a control key, and the energy storage element is connected with a wire, which is connected to the heating ring. The outer semi-ring frame, inner ring, insertion end, heat-conducting plate, and heat-conducting column are made of heat-conducting material; the heating ring is heated by short-circuiting; the heat-conducting material is copper.

[0011] Furthermore, the inner ring is a ring structure with an optimal arc of 190-200 degrees.

[0012] After penetrating the tissue, due to the elasticity of the tissue, the entry of the device tip will compress the tissue. After entering the tissue, the tissue returns to its original shape in the inner ring position and is squeezed into the inner ring, so that the tissue in the inner ring blocks the passage between the upper and lower parts of the tissue. Alternatively, while maintaining the engagement of the drive gear and the middle gear and the ring pad not falling out of the main cylinder, the tissue can be filled in the half-ring position by pulling out part of the air plug.

[0013] The beneficial effects of this invention are: A urinary system tumor peritumoral sampling device is used in organ-sparing surgery for renal pelvis cancer. During use, the insertion end is inserted into the edge of the surgically removed tumor tissue. A motor drives a gear, causing the middle gear to rotate 180 degrees. This, through a limiting groove and engagement with an upper rod, causes the inner ring within the outer half-ring to rotate, shearing the tissue. Simultaneously, during the inner ring shearing process, the middle gear and rack engage, causing the movable ring to press against the fixed ring, activating a compression spring. After the inner ring shearing is complete, the inclined seat engages with a trigger rod, lifting the trigger rod upwards and disengaging the fixed ring from the trigger rod. The fixed ring, via a connecting column, allows pistons on both sides to slide within air cylinders on either side, controlled by an inflation tube. The negative pressure tube and central vent reduce the gas on the upper side of the tissue and replenish the gas on the lower side of the heat-conducting plate. This allows the heat-conducting plate to pull the tissue upward away from the heating ring, outer half-ring frame, inner ring, and insertion end. By controlling the control key, the heating ring heats up, and through the heat conduction of the outer half-ring frame, inner ring, and insertion end, the location of the acquired tissue is cut, completing an immediate and convenient hemostasis operation. At the same time, due to the function of the heat insulation ring and heat insulation plate, the tissue is prevented from being deformed by heating. Furthermore, due to the presence of the heat-conducting column, some heat is transferred to the non-cancerous side of the tissue for cauterization, thus marking the tissue and completing the tissue adjacent to the cancerous side, avoiding the problem of false negative test results.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

During the shearing process of the inner ring (113), the intermediate gear (203) and the rack (220) cooperate to press the compression spring (223) against the fixed ring (224) on the movable ring. After the inner ring (113) completes the shearing, the inclined seat (205) cooperates with the trigger rod (230). The trigger rod (230) is lifted upward to disengage the fixed ring (224) from the trigger rod (230). The fixed ring (224) then connects to the pistons (226) on both sides via the connecting column (225).

(112) The heat conduction of the inner ring (113) and the insertion end (114) allows for the cutting of the tissue at the location of acquisition, enabling immediate and convenient hemostasis. At the same time, due to the function of the heat insulation ring (110) and the heat insulation plate (122), the tissue is prevented from being heated and deformed. Furthermore, due to the presence of the heat conduction column (121), some heat is transferred to the non-cancerous side of the tissue for cauterization, thereby marking the tissue and completing the marking of the tissue's adjacent cancerous side, thus avoiding the problem of false negative test results.
