Description

Technical Field

[0001] The utility model belongs to the technical field of surgical medical instruments, and in particular relates to a drainage catheter fixer for surgical operations. Background Art

[0002] Drainage catheter is a medical device used for clinical surgical drainage, which guides the pus, blood and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage catheters used in clinical practice, some are used for urinary catheterization, some are used for wounds, chest cavity, brain cavity, gastrointestinal tract and bile duct.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: when the drainage catheter is used, it is connected to an instrument that directly extracts (or otherwise discharges) pus, blood, and liquid from the human body, and then the drainage catheter is extended to the position where the above liquid is collected, but the drainage catheter also needs to be roughly fixed in position by a fixer to avoid damage or functional failure of the drainage catheter due to reasons such as walking of people. In order to expand the range of guiding and limiting the drainage catheter, the current fixer uses some longer rods (extending to a position closer to the patient's body) to fix the drainage catheter, but the longer rods also cause the fixer to be larger in size and occupy a large space, which is not convenient for storage and movement (for example, the cross bar 6 in the patent application number CN202122250516.X, a drainage tube fixator for abdominal surgery, occupies a large space and cannot be retracted).

[0004] For this reason, we propose a drainage catheter fixer for surgical operation to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a drainage catheter holder for surgical operations, which can be retracted toward the center rod when the receiving rod is not in use, and flipped to a vertical state (close to the center rod), thereby not having to occupy too much space, improving the experience of storage and movement, and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Rollers 2 are installed at the four corners of the bottom wall of the base 1, and the four rollers 2 are arranged in a rectangular array distribution, so that the base 1 and the structure thereon can move with the rolling of the four rollers 2, thereby improving the mobility of the base 1;

[0024] A storage seat 3 is welded on one side of the top wall of the base 1, wherein a receiving tank 4 for containing pus, blood and other liquids in the human body is inserted in the vertical direction on the storage seat 3, and the fixing mechanism includes a central rod 5 fixedly welded at the center of the top wall of the base 1, a support 11 movably connected to the top of the central rod 5, and a receiving rod 13 connected to one side of the support 11;

[0025] A mounting bottom groove 6 is formed at the bottom of the center rod 5, and a knob 7 is rotatably connected to the center rod 5. The knob 7 is installed on the top wall of the mounting bottom groove 6, so that the knob 7 can be fixed and hidden in the mounting bottom groove 6 to prevent the knob 7 from being touched by external objects. A top sliding groove 8 is formed on the top wall of the center rod 5, and a screw rod 9 is coaxially connected above the knob 7. The screw rod 9 is vertically arranged and rotatably connected to the bottom wall of the top sliding groove 8, so that the screw rod 9 can operate stably. A limit slide 10 is threadedly sleeved on the screw rod 9, and the limit slide 10 is in contact with the inner wall of the top sliding groove 8. The support 11 is L-shaped, and the bottom wall of the support 11 is welded to the limit slide 10.

[0026] An extension frame 12 is installed on the side of the support 11 facing away from the limiting slide 10, a first rotating shaft is installed on the inner side of the extension frame 12, and the extension frame 12 is connected to the receiving rod 13 through the first rotating shaft, and a plurality of limiting hooks 14 are fixedly bonded on the receiving rod 13 and the center rod 5, and the plurality of limiting hooks 14 on the receiving rod 13 and the plurality of limiting hooks 14 on the center rod 5 are evenly distributed along a straight line, the limiting hooks 14 can be made of rubber material, and the limiting hooks 14 have an opening for the drainage catheter to pass through and be clamped therein, a penetration groove 15 is provided on the side of the receiving rod 13 close to the extension frame 12, so that the drainage catheter can be guided toward the limiting hook 14 on the center rod 5 through the penetration groove 15, a second rotating shaft is installed on the bottom wall of the support 11, and the support 11 is connected to a fixed block 16 that abuts the receiving rod 13 in a horizontal state through the second rotating shaft.

[0027] The drainage catheter holder for surgical operation: when installing, first connect one end of the drainage catheter for surgical operation to an instrument for guiding pus, blood, liquid, etc. in the human body, so that the instrument (which is the prior art and will not be described here) guides the above liquid out of the human body through the drainage catheter. Therefore, the drainage catheter needs to be first clamped on the multiple limiting hooks 14 on the receiving rod 13, then pass through the penetration groove 15 and clamped in the multiple limiting hooks 14 on the central rod 5, and finally the end of the drainage catheter extends into the receiving tank 4, so that the pus, blood, liquid, etc. in the human body can be guided into the receiving tank 4;

[0028] When in actual use, the height of the receiving rod 13 can be adjusted according to the height of the patient. The adjustment method is as follows: turning the knob 7 drives the screw rod 9 to operate, so that the limiting slide 10 can slide up or down along the inner wall of the top slide groove 8, thereby driving the support 11 and the receiving rod 13 to rise and fall, so as to change the height of the receiving rod 13, and then the receiving rod 13 is flipped to a horizontal state along the first rotating shaft, and the fixing block 16 is flipped along the second rotating shaft and abuts against the horizontal receiving rod 13 to ensure the stability of the receiving rod 13 (when the receiving rod 13 is not in use, the fixing block 16 is first flipped 180° along the second rotating shaft, at which time the fixing block 16 is disengaged from the receiving rod 13, and then the receiving rod 13 is flipped 90° along the first rotating shaft, so that it is parallel to the center rod 5, reducing the space occupied by the receiving rod 13, and the knob 7 can be turned to drive the receiving rod 13 to descend, further reducing the occupied space); since the adjustment and use of the receiving rod 13 are more flexible, it is more ideal in extracorporeal circulation or cardiac surgery.
