Description

Drainage catheter fixer for surgical operation

Technical Field

The utility model belongs to the technical field of surgical medical instruments, and particularly relates to a drainage catheter fixer for surgical operation.

Background

The drainage catheter is a medical instrument for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or cavities to the outside of the body, prevents postoperative infection and promotes wound healing. Surgical drainage catheters for clinical use are of a wide variety, some for catheterization and others for wounds, chest, brain cavities, gastrointestinal tract and biliary tract.

In carrying out the present utility model, the inventors have found that there is at least a problem in this technique in that, when the drainage catheter is used, it is connected to an apparatus for directly drawing out (or otherwise discharging) pus, blood, or liquid from the human body, and then the drainage catheter is extended to a position where the liquid is collected, but the drainage catheter is still required to be substantially fixed in position by a holder, so that damage or malfunction of the drainage catheter due to walking of a person or the like is avoided. Current holders use longer rods (extending to a position closer to the patient's body) to hold the drainage catheter in order to expand the scope of guiding and restraining the drainage catheter, but longer rods also result in larger holders that occupy more space and are not easy to store and move (e.g., the crossbar 6 in the abdominal surgical drainage tube holder of patent application No. cn202122250516.X takes up more space and cannot collapse).

To this end, we propose a surgical drainage catheter holder that solves the above-mentioned problems.

Disclosure of utility model

the rotary knob is rotationally connected to the center rod, a top sliding groove is formed in the top wall of the center rod, a screw is coaxially connected to the upper side of the knob, a limit sliding seat is sleeved on the screw in a threaded manner, the limit sliding seat is attached to the inner wall of the top sliding groove, the support is L-shaped, and the bottom wall of the support is welded to the limit sliding seat;

an extension frame is arranged on one side of the support, which is opposite to the limit sliding seat, a first rotating shaft is arranged on the inner side of the extension frame, the extension frame is connected with a receiving rod through the first rotating shaft, a plurality of limit hooks are fixedly bonded on the receiving rod and the center rod, a second rotating shaft is arranged on the bottom wall of the support, and the support is connected with a fixing block which is in butt joint with the receiving rod in a horizontal state through the second rotating shaft.

The four corners of the bottom wall of the base are provided with the rollers, the four rollers are distributed in a rectangular array mode, the base and the structure on the base can move along with the rolling of the four rollers, and the moving convenience of the base is improved.

As a preferred embodiment, a mounting bottom groove is formed at the bottom of the center rod, and the knob is mounted on the top wall of the mounting bottom groove, so that the knob can be fixed and hidden in the mounting bottom groove to avoid touching of the knob by external objects.

As a preferred embodiment, the screw is vertically disposed and rotatably connected to the bottom wall of the top chute so that the screw can be stably operated.

The limiting hooks on the receiving rod and the limiting hooks on the central rod are distributed at equal intervals along a straight line, the limiting hooks can be made of rubber materials and are provided with an opening for enabling the drainage catheter to pass through and be clamped in the limiting hooks.

As a preferred embodiment, a penetration groove is formed on one side of the receiving rod near the extension frame, so that the drainage catheter can be guided towards the limit hooks on the central rod through the penetration groove.
