Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a minimally invasive drainage tube bracket. Background Art

[0002] At present, there is no specially designed drainage fixation device for minimally invasive puncture and drainage operations. Drainage is mainly fixed by simple external objects or other tools at the bedside. In this way, when the staff is operating, the drainage tubes may be folded and entangled with each other due to body contact, causing the drainage tubes to be blocked, thus affecting their use. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides a minimally invasive drainage tube bracket.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a minimally invasive drainage tube bracket, comprising a support rod, characterized in that: a clamping assembly is installed at the bottom of the support rod, and a fixing assembly is provided on the outer peripheral side of the support rod;

[0005] The fixing assembly includes an upper swivel and a lower swivel that rotate on the support rod, and extension rods are fixed on the outer circumferences of the upper swivel and the lower swivel, and a mounting block is fixed on the extension rod. A buckle is movably linked in the mounting block, and an upper limit rod and a lower limit rod are slidably provided inside the support rod, and the upper limit rod and the lower limit rod are connected together by a spring.

[0006] Optionally, a sliding groove is provided on the outer peripheral side of the support rod between the upper swivel ring and the lower swivel ring, and the upper limit rod and the lower limit rod are located in the sliding groove.

[0007] Optionally, an upper limit groove is provided on the end surface of the upper swivel close to the lower swivel, and a lower limit groove is provided on the end surface of the lower swivel close to the upper swivel, wherein the upper limit groove is located on the side of the upper swivel close to the extension rod, and the lower limit groove is located on the side of the lower swivel away from the extension rod.

[0008] Optionally, a spherical groove is provided in the mounting block, the buckle is located in the spherical groove, the buckle is also spherical, and notches are provided in both the mounting block and the buckle.

[0009] Optionally, the clamping assembly includes a fixed hinge block rotatably connected to the bottom of the support rod, and an elastic clip is fixed to the bottom of the fixed hinge block.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the fixing assembly, when the relative angle of the upper swivel and the lower swivel is less than 180 degrees, at least one of the extension rods is guaranteed to be active, so that the drainage tube cannot be folded no matter how it swings. When the relative angle of the upper swivel and the lower swivel is about to be greater than 180 degrees, it will be stuck by the upper limit rod and the lower limit rod, thereby effectively preventing the drainage tube from being folded and entangled.

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in Figure 1-2, a minimally invasive drainage tube bracket includes a support rod 10, a clamping assembly is installed at the bottom of the support rod 10, the clamping assembly includes a fixed hinge block 11 rotatably connected to the bottom of the support rod 10, an elastic clip 12 is fixed to the bottom of the fixed hinge block 11, a fixing assembly is provided on the outer periphery of the support rod 10, the fixing assembly includes an upper swivel 13 and a lower swivel 14 rotating on the support rod 10, an extension rod 15 is fixed on the outer periphery of the upper swivel 13 and the lower swivel 14, an upper limit groove 21 is provided on one end face of the upper swivel 13 close to the lower swivel 14, and the lower swivel 14 close to the upper swivel 13 is provided with a lower limit groove 21. A lower limit groove 20 is provided on one end surface, wherein the upper limit groove 21 is located on the side of the upper swivel 13 close to the extension rod 15, and the lower limit groove 20 is located on the side of the lower swivel 14 away from the extension rod 15. A mounting block 16 is fixed on the extension rod 15, and a buckle 17 is movably linked in the mounting block 16. An upper limit rod 18 and a lower limit rod 19 are also slidably provided inside the support rod 10, and the upper limit rod 18 and the lower limit rod 19 are connected together by a spring. A sliding groove is provided on the outer peripheral side of the support rod 10 between the upper swivel 13 and the lower swivel 14, and the upper limit rod 18 and the lower limit rod 19 are located in the sliding groove.

[0017] A spherical groove is provided in the mounting block 16 , and the buckle 17 is located in the spherical groove. The buckle 17 is also spherical in shape, and notches are provided in both the mounting block 16 and the buckle 17 .

[0018] When in use, the drainage tube can be buckled into the two buckles 17 through the notch, and then the elastic clip 12 can be clamped on an object such as a bedside, and then the support rod 10 can be rotated to adjust the position of the support rod 10. There is a certain damping between the support rod 10 and the fixed hinge block 11. During the use of the drainage tube, the drainage tube will move and swing around. At this time, the extension rods 15 on both sides can be driven to rotate through the mounting block 16. However, if the upper and lower sides of the drainage tube have different swinging directions, when the upper swivel 13 rotates to the upper limit slot 21 corresponding to the upper limit rod 18, the upper limit rod 18 can enter the upper limit slot 21 under the thrust of the spring, thereby limiting the upper swivel 13 from continuing to swing, and the lower swivel 14 swings to the lower limit The rod 19 corresponds to the lower limit groove 20. At this time, the lower limit rod 19 enters the lower limit groove 20 under the thrust of the spring, which can limit the lower swivel 14 from continuing to swing, thereby preventing the drainage tube from folding when the lower swivel 14 and the upper swivel 13 swing in different directions, and then preventing the drainage tube from being blocked and unusable. When the relative angle of the upper swivel 13 and the lower swivel 14 is less than 180 degrees, at least one of the extension rods 15 is in an active state, so that the drainage tube cannot be folded no matter how it swings. When the relative angle between the upper swivel 13 and the lower swivel 14 is about to be greater than 180 degrees, it will be stuck by the upper limit rod 18 and the lower limit rod 19, thereby effectively preventing the drainage tube from folding and entanglement.

[0019] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
