Description

Technical Field

[0001] This utility model relates to the field of urological bladder tumor treatment technology, and in particular to a removal device after en bloc removal of a bladder tumor. Background Technology

[0002] The bladder tumor enucleation removal device is a specialized instrument used in urological surgery. Its main purpose is to safely and completely remove the enucleated tumor tissue from the bladder. This is crucial for the accuracy of subsequent pathological examinations and for preventing residual tumor cells from spreading within the bladder.

[0003] A search revealed Chinese Patent Publication No. CN219878202U, which discloses a device for removing bladder tumors after en bloc resection. The device includes a retrieval basket, an inner core, an outer sheath, a first operating handle, and a second operating handle. The retrieval basket comprises two arc-shaped support filaments, one arc-shaped support filament, and a storage bag. The two arc-shaped support filaments and the one arc-shaped support filament are connected sequentially to form an elliptical support ring. The opening of the storage bag is connected to the support ring. The inner core includes two guide wires and one guide wire. The front end of guide wire one is connected to the junction of the arc-shaped support filaments, and the other end of guide wire one is connected to the first operating handle. The front end of guide wire two is connected to the junction of the two arc-shaped support guide wires, and guide wire two is connected to the second operating handle. The foldable retrieval basket, equipped with a nylon mesh storage bag, can effectively reduce the spread of tumor cells and lower the possibility of postoperative recurrence during en bloc resection of bladder tumors. However, when medical staff remove the tumor, their hands and the anesthetized patient's body may make slight movements, which may cause the retrieval device to shift inside the patient's body and thus harm the patient's health. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a removal device after en bloc removal of bladder tumors. It aims to improve the problem in the prior art where, during the tumor removal operation, the slight movements of the hands and the body of the anesthetized patient can cause the removal device to shift inside the patient's body and cause harm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for removing a bladder tumor after en bloc resection, comprising a hollow long tube, wherein multiple U-shaped long pieces are fixedly connected at equal intervals around the outer wall of the hollow long tube, a second connecting rod is rotatably connected inside the U-shaped long pieces, an H-shaped block is rotatably connected to the top of the second connecting rod, a first connecting rod is rotatably connected to the upper middle part of the inner wall of the H-shaped block, a short U-shaped piece is rotatably connected to the outer wall of the first connecting rod, a hollow bottom block is fixedly connected to the outer wall of the short U-shaped piece, multiple springs are fixedly connected at equal intervals inside the hollow bottom block, a hollow top ring is fixedly connected to the top of the springs, a pull rope is installed on the rear side of the outer wall of the hollow long tube, and a sorting mechanism is installed inside the hollow long tube to sort the pull rope to prevent tangling during pulling.

[0006] As a further description of the above technical solution:

[0007] The sorting mechanism includes an elongated hollow block, which is installed on the rear side of the outer wall of a hollow tube. A threaded rod is rotatably connected inside the elongated hollow block, and a movable block is threadedly connected to the outer wall of the threaded rod. A roller one is rotatably connected to the lower middle part of the inner wall of the hollow tube, and a roller two is fixedly connected to the left side of the outer wall of the movable block. An inner sliding groove block is fixedly connected to the bottom of the elongated hollow block, and a fixed rod is slidably connected inside the inner sliding groove block. The top of the fixed rod is fixedly connected to the bottom of the movable block.

[0008] As a further description of the above technical solution:

[0009] An anti-slip sleeve is fixedly connected to the lower middle part of the outer wall of the hollow tube.

[0010] As a further description of the above technical solution:

[0011] A pull ring is fixedly connected to the bottom end of the pull rope.

[0012] As a further description of the above technical solution:

[0013] The top of the hollow top ring is fixedly connected with an anti-slip pad.

[0014] As a further description of the above technical solution:

[0015] A throttle is fixedly connected to the right end of the outer wall of the threaded rod.

[0016] As a further description of the above technical solution:

[0017] A protective sleeve is fixedly connected to the outer wall of the throttle.

[0018] As a further description of the above technical solution:

[0019] The bottom of the hollow tube is fixedly connected to a hook.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the hollow top ring compresses the spring inside the hollow bottom block to reduce the movement amplitude. Then, the connecting rod one inside the U-shaped short piece and the connecting rod two in the lower part of the inner wall of the H-shaped block rotate outward to release the force of movement. The hollow long tube in the middle of the hollow bottom block will not be affected and will not shift. This avoids the problem that the removal device may be displaced in the patient's body and cause harm to the patient due to slight movements of the hands and the body of the anesthetized patient when medical staff remove tumors.

[0022] 2. In this utility model, by rotating the threaded rod inside the elongated hollow block, the threaded rod will drive the moving block on the outer wall to move while rotating. Then, the moving block will drive the roller two on the left side of the outer wall to clamp and straighten the pull rope with the roller one, thereby avoiding the problem of the pull rope getting tangled during use and causing inconvenience to subsequent surgical work.

The pull ring 15 can facilitate pulling the pull rope 14.

[0032] Specifically, by using the hollow top ring 4 to hold the patient's body in place, when the patient's body makes slight movements or the doctor's hand trembles, the hollow top ring 4 will compress the spring 16 inside the hollow bottom block 17 to slow down the movement. Then, the connecting rod 7 inside the U-shaped short piece 5 and the connecting rod 9 in the lower middle part of the inner wall of the H-shaped block 8 will rotate outward to release the movement force. The hollow long tube 1 in the middle of the hollow bottom block 17 will not be affected and will not shift. The lower middle part of the outer wall of the hollow long tube 1 is fixedly connected to the anti-slip sleeve 10, which can prevent medical staff from slipping and dropping the device when picking it up. The bottom end of the pull rope 14 is fixedly connected to the pull ring 15, which can facilitate pulling the pull rope 14.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The sorting mechanism 2 includes a long hollow block 201, which is installed on the rear side of the outer wall of the hollow tube 1. A threaded rod 203 is rotatably connected inside the long hollow block 201, and a movable block 206 is threadedly connected to the outer wall of the threaded rod 203. By rotating the threaded rod 203, the movable block 206 on the outer wall can be moved and adjusted. A roller 1 204 is rotatably connected to the lower middle part of the inner wall of the hollow tube 1, and a roller 205 is fixedly connected to the left side of the outer wall of the movable block 206. The pull rope 14 is clamped by the roller 1 204 and the roller 205 to achieve the sorting effect. The bottom of 01 is fixedly connected to an inner sliding block 202. The inner sliding block 202 is slidably connected to a fixed rod 207. The top of the fixed rod 207 is fixedly connected to the bottom of the moving block 206.

[0036] Specifically, a protective sleeve 12 is fixedly connected to the outer wall of the throttle 11. The protective sleeve 12 can enhance the comfort of medical staff's hands when turning the throttle 11. A hook 13 is fixedly connected to the bottom of the hollow long tube 1. The hook 13 can temporarily hang the device when it is not in use to avoid damage.

[0037] Working principle: The hollow top ring 4 is used to hold the patient's body in place. When the patient's body makes a slight movement or the doctor's hand trembles, the hollow top ring 4 will compress the spring 16 inside the hollow bottom block 17 to slow down the movement. Then, the connecting rod 7 inside the U-shaped short piece 5 and the connecting rod 9 in the lower part of the inner wall of the H-shaped block 8 will rotate outward to release the force of movement. The hollow long tube 1 in the middle of the hollow bottom block 17 will not be affected and will not shift. This avoids the problem that the removal device may shift inside the patient's body and cause harm due to slight movements of the hands and the body of the anesthetized patient when medical staff remove tumors.

[0038] By rotating the threaded rod 203 inside the elongated hollow block 201, the threaded rod 203 will drive the moving block 206 on the outer wall to move. Then, the moving block 206 will drive the roller 205 on the left side of the outer wall to clamp and straighten the pull rope 14 with the roller 204, thereby avoiding the problem of the pull rope 14 getting tangled during use and causing inconvenience to subsequent surgical work.
