Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a catheter fixing device for intestinal tumor surgery. Background Art

[0002] Oncology surgery is a surgical department in a hospital. Its main task is to perform surgery and treat various tumors. After the operation, catheter drainage is required. A hole is opened in the abdomen, and then a catheter is inserted into the abdomen to drain the excrement. The outer end of the catheter needs a fixing device to fix it to the abdomen, usually with tape. However, tape is uncomfortable to use and has poor fixation. The current fixing device is inconvenient to operate, so the catheter cannot be quickly fixed, thereby delaying medical work. The outer end of the catheter may be bent, which affects the drainage effect of the catheter. In view of this, in-depth research was conducted on the above-mentioned problems, which led to this case. Utility Model Content

[0003] The utility model aims to provide a catheter fixing device for intestinal tumor surgery to solve the problem that the existing catheter fixing device for intestinal tumor surgery mentioned in the background technology does not have the functions of rapid fixing and preventing the catheter from bending.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a catheter fixing device for intestinal tumor surgery, comprising a second movable claw, a device body and a movable sleeve, a mounting frame is installed on the inner wall of the device body, and the second movable claw is movably installed on the inner wall of the mounting frame through a rotating shaft, one end of the second movable claw is movably connected to the first movable claw, and the inner walls above the first movable claw and the second movable claw are both installed with second splints, a mounting rod is installed below the inner wall of the device body, and the mounting rod passes through the bottom of the first movable claw and the second movable claw, a left tightening belt is connected to one side of the device body, and a right tightening belt is connected to the other side of the device body, and a mounting shell is installed on both sides of one end of the device body.

[0005] Preferably, second return springs are installed on the outer walls at both ends of the mounting rod, and one end of the second return spring is fixedly connected to the outer walls below the first movable claw and the second movable claw.

[0006] Preferably, a rotating shaft is installed below the first movable claw and the second movable claw, and rollers are installed on the outer walls of the rotating shaft.

[0007] Preferably, a first return spring is installed on the outer wall below the device body, and a movable rod is installed on the inner side of the first return spring, and a pull ring is connected to the bottom end of the movable rod.

[0008] Preferably, the top end of the movable rod is connected to an extrusion block, and the three-dimensional front view of the extrusion block is a conical column.

[0009] Preferably, an adhesive fleece patch is installed on the inner wall of one end of the left tightening belt, and an adhesive thorn patch matching with the adhesive fleece patch is installed on the inner wall of one end of the right tightening belt.

[0010] Preferably, a threaded rod is installed on the inner wall of the mounting shell, and one end of the threaded rod is connected to an adjusting knob, and a movable sleeve is threadedly installed on the outer wall of the threaded rod, and one side of the movable sleeve is connected to a first clamping plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model provides a pull ring, an extrusion block and a second return spring. By pushing the pull ring upward, the movable rod drives the extrusion block upward at the same time, and the first return spring is squeezed and deformed. Then the extrusion block moves upward to between the rollers, and the rollers roll on the extrusion block. The extrusion block is smaller at the top and larger at the bottom. As the extrusion block rises, the distance between the rollers gradually increases. At the same time, the second return spring is squeezed and deformed. Then the distance above the first movable claw and the second movable claw increases. Then the catheter is placed between the second clamping plates. After loosening the pull ring, the first return spring is reset to make the extrusion block drop away from between the rollers. At the same time, the second return spring is reset to make the distance between the rollers smaller and reset. At the same time, the distance between the first movable claw and the second movable claw decreases and resets. The catheter is clamped and fixed. The medical staff pushes the pull ring upward to place the catheter. After releasing the hand, the second clamping plate clamps the catheter, solving the problem of inconvenient quick fixation.

[0013] (2) The utility model provides a first clamping plate, an adjusting knob and a moving sleeve. The catheter is placed between the first clamping plates for positioning. The adjusting knob is rotated to rotate the threaded rod. The threads cooperate to make the moving sleeve drive the first clamping plate to move forward. The front end of the catheter is positioned by the first clamping plate to avoid bending of the front end of the catheter, making the catheter transportation smoother and solving the problem of catheter bending.

The extrusion block 9 is small at the top and large at the bottom. As the extrusion block 9 rises, the distance between the rollers 13 gradually increases. At the same time, the second return spring 14 is squeezed and deformed, and then the distance above the first movable claw 3 and the second movable claw 4 increases;

[0032] Step 2: Then place the catheter between the second clamping plates 21, loosen the pull ring 11, and the first reset spring 10 resets the extrusion block 9 to move down away from the rollers 13, and at the same time, the second reset spring 14 resets the rollers 13 to reduce the distance between them, and at the same time, the distance between the first movable claw 3 and the second movable claw 4 is reduced and reset, so that the catheter is clamped and fixed.

[0033] The second innovation point implementation steps:

[0034] The catheter is positioned between the first clamping plates 16, and the threaded rod 19 is rotated by rotating the adjusting knob 18. The threads are matched so that the movable sleeve 20 drives the first clamping plate 16 to move forward. The front end of the catheter is positioned by the first clamping plate 16 to avoid bending of the front end of the catheter, making the catheter transportation smoother.
