[0002] With the development of science and technology, the number of traditional open surgeries in clinical gastrointestinal surgery is increasingly being reduced. Catheter interventional therapy, as a commonly used medical method in clinical gastrointestinal surgery, is the basic technical prerequisite for minimally invasive gastrointestinal surgery.

[0003] The existing catheter clamping device generally adheres to the patient's skin through a first layer of adhesive tape, and then adheres and fixes the catheter to the first layer of adhesive tape through a fixing tape. However, when the fixing tape is used to adhere and fix a catheter with a larger diameter, when the fixing tape adheres to the first layer of adhesive tape on the patient's skin, the catheter on the patient moves with the patient, and the fixing tape stuck on the first layer of adhesive tape will become loose and fall off, resulting in poor fastening.

[0006] Preferably, a buckle is fixedly connected to the right end of the half-moon ring.

[0007] Preferably, a tightening belt is fixedly connected to the left side of the half-moon ring.

[0008] Preferably, the buckle and the tightening belt are engaged with each other.

[0009] Preferably, one opposite end of the two threaded rods is fixedly connected with a rotating member.

[0010] Preferably, the inner walls of the first limiting ring and the second limiting ring are both provided with evenly distributed suction cups.

[0011] The beneficial effects of the utility model are as follows:

[0012] In the utility model, the threaded rod is rotated to move downward in the nut, pushing the first limiting ring and the second limiting ring to move toward the adjacent end, and at the same time, the connecting rod will also move along with the sliding of the slider in the slide groove, and both sides of the second limiting ring pass through the first embedding groove. At the same time, the first embedding groove and the second embedding groove pass through the adjacent connecting rod, thereby compressing the space between the first limiting ring and the second limiting ring, so that the catheter can be squeezed, and the fixation of the catheter itself is improved, thereby achieving the effect of fixing various types of catheters.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-3The adjustable catheter fixer shown in the figure includes a half-moon ring 1, a fixing groove 7 is penetrated and provided at the front end of the half-moon ring 1, a nut 4 is penetrated and provided at the middle position between the top and the bottom of the half-moon ring 1, the inner walls of the two nuts 4 are threadedly connected with threaded rods 8, the adjacent ends of the two threaded rods 8 are rotatably connected with rotating shafts 11, and the two rotating shafts 11 are respectively fixedly connected with a first limiting ring 5 and a second limiting ring 9, the bottom sides of the first limiting ring 5 are penetrated and provided with a first embedding groove 14, the bottom sides of the second limiting ring 9 are penetrated and provided with a second embedding groove 15, the inner walls of the fixing groove 7 are penetrated by the half-moon ring 1 on both sides and are provided with a slide groove 6, the inner walls of the two slide grooves 6 are slidably connected with a slider 10, the adjacent sides of the two sliders 10 at the same end are fixedly connected with a connecting rod 13, and the four connecting rods 13 are fixedly connected between the adjacent first limiting ring 5 and the second limiting ring 9.

[0019] The user fixes the tightening belt on the designated part of the patient, and rotates the threaded rod 8 to move the threaded rod 8 downward in the nut 4. At the same time, the threaded rod 8 rotates in the rotating shaft 11, pushing the first limiting ring 5 and the second limiting ring 9 to move toward the adjacent end. At the same time, the connecting rod 13 will also move along with the sliding of the slider 10 in the sliding groove 6, so as to prevent the first limiting ring 5 and the second limiting ring 9 from rotating with the rotation of the threaded rod 8, and at the same time, the first limiting ring 5 and the second limiting ring 9 can be supported and fixed.
