Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a retractable U-shaped frame. Background Art

[0002] At present, the common method of cleaning and disinfecting surgical instruments is to manually string the surgical instruments to be cleaned and disinfected on a fixed U-shaped rack for cleaning and disinfection, and then take them out. In order to thoroughly clean and disinfect, the axis of the surgical instrument must be fully unfolded, but in order to facilitate assembly, packaging, sterilization, storage and transportation, the fully unfolded surgical instruments need to be closed. The traditional open U-shaped rack cannot adjust the width, length and fixing function, resulting in the use of three U-shaped racks in combination to fully open the instrument or the opening cannot be fully exposed to the best cleaning position. When packing, two people need to cooperate to close the instrument, which is cumbersome, time-consuming and labor-intensive.

[0003] For example, patent CN210330774U provides a U-shaped surgical instrument string that is easy to retract. The patented device is equipped with a new bottom rod and extension rod to realize the expansion function of the bottom of the utility model. The medical device installed and fixed on the utility model will move accordingly, and the shaft joints on the medical device will all be opened, which is convenient for users to clean and disinfect the medical device. However, the bottom rod and extension rod in the above patent can only adjust the distance between the fixed rods on both sides, but the adjustment distance is limited and cannot adapt to the scene with a small instrument opening. Utility Model Content

[0004] The present application provides a retractable U-shaped frame to solve the above-mentioned technical problems.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: a retractable U-shaped frame, comprising two parallel fixed rods, a strip rotating piece located at the end of the fixed rod, and a telescopic rod connecting the two fixed rods, wherein the telescopic rod includes a positioning bead for adjusting the distance between the fixed rods and a bending shaft for adjusting the angle of the telescopic rod.

[0006] Furthermore, the telescopic rod also includes a sleeve connected to the fixed rod and an inner tube connected to another fixed rod, the sleeve is sleeved on the outside of the inner tube, wherein the outer wall of the inner tube close to the fixed rod is provided with positioning beads, and the sleeve is provided with multiple groups of linearly arranged positioning holes.

[0007] Furthermore, the positioning bead is located in the embedding groove of the inner tube, and a spring is provided between the bottom of the embedding groove and the positioning bead.

[0008] Furthermore, the inner diameter of the opening of the embedding groove is smaller than the outer diameter of the positioning bead.

[0009] Furthermore, a limiting plate is provided at the end of the sleeve close to the inner tube, and the inner tube is inserted into the central opening of the limiting plate, wherein a limiting block is provided at one end of the inner tube that is sleeved on the inner tube.

[0010] Furthermore, the inner tube includes a first tube body connected to the limit block and a second tube body connected to the fixing rod. A first connecting part is provided at an end of the first tube body close to the second tube body, and a second connecting part is provided at an end of the second tube body close to the first tube body. The first connecting part and the second connecting part are movably connected through a bending shaft.

[0011] Furthermore, the bending shaft is located between the limiting block and the positioning bead.

[0012] Furthermore, the upper end of the fixing rod is provided with a strip groove corresponding to the strip rotating piece, and the middle part of the strip rotating piece is embedded in the strip groove and movably connected to the fixing rod through the first rotating shaft.

[0013] The beneficial effect of the present application is that the present application can effectively adjust the distance between the fixed rods by extending and retracting the telescopic rod.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] like Figure 1-4 As shown, a telescopic U-shaped frame includes two fixed rods 1 arranged in parallel, a strip-shaped rotating piece 2 located at the end of the fixed rod 1, and a telescopic rod 3 connecting the two fixed rods 1, wherein the telescopic rod 3 includes a positioning bead 31 for adjusting the distance between the fixed rods 1 and a bending shaft 32 for adjusting the angle of the telescopic rod 3. The telescopic rod 3 in the above design can adjust the distance between the fixed rods 1 by telescoping, and the bending shaft 32 can bend the telescopic rod 3, thereby further retracting the distance between the fixed rods 1, so that the fixed rods 1 can extend into and open the device with a smaller opening.

[0020] The telescopic rod 3 also includes a sleeve 33 connected to the fixed rod 1 and an inner tube 34 connected to another fixed rod 1, wherein the sleeve 33 is sleeved on the outer side of the inner tube 34, wherein the outer wall of the inner tube 34 close to the fixed rod 1 is provided with a positioning bead 31, and the sleeve 33 is provided with a plurality of linearly arranged positioning holes 35. The positioning bead 31 in the above design is used to be embedded in the positioning hole 35, so as to determine the position of the inner tube 34. In other embodiments, the positioning hole 35 can also be embedded by means of a positioning pin or the like.

[0021] The positioning bead 31 is located in the embedding groove 341 of the inner tube 34, and a spring 4 is provided between the bottom of the embedding groove 341 and the positioning bead 31. The positioning bead 31 in the above design can be retracted into the embedding groove 341 under the action of external force, so that the inner tube 34 can slide in the sleeve 33 to adjust the length of the telescopic rod 3.

[0022] The opening inner diameter of the embedding groove 341 is smaller than the outer diameter of the positioning bead 31 , so as to prevent the positioning bead 31 from being separated from the embedding groove 341 .

[0023] A stop plate 331 is provided at the end of the sleeve 33 near the inner tube 34, and the inner tube 34 is inserted into the central opening of the stop plate 331, wherein the inner tube 34 is sleeved on one end of the inner tube 34 and a stop block 342 is provided. The stop plate 331 and the stop block 342 in the above design can prevent the inner tube 34 from detaching from the sleeve 33.

[0024] The inner tube 34 includes a first tube body 343 connected to the stop block 342 and a second tube body 344 connected to the fixing rod 1. The first tube body 343 is provided with a first connecting portion 345 at an end close to the second tube body 344, and the second tube body 344 is provided with a second connecting portion 346 at an end close to the first tube body 343. The first connecting portion 345 and the second connecting portion 346 are movably connected via a bending shaft 32. The first connecting portion 345 and the second connecting portion 346 in the above design can be further rotated by the bending shaft 32, so that the inner tube 34 is bent to further retract the distance between the fixing rods 1.

[0025] The bending shaft 32 is located between the limit block 342 and the positioning bead 31. The above design ensures that when the positioning bead 31 is inside the sleeve 33, the bending shaft 32 is also located in the sleeve 33, thereby ensuring that the telescopic rod 3 will not bend when it is extended or retracted.

[0026] The upper end of the fixing rod 1 is provided with a strip groove 11 corresponding to the strip rotating piece 2, and the middle part of the strip rotating piece 2 is embedded in the strip groove 11 and movably connected to the fixing rod 1 through the first rotating shaft 12. The strip groove 11 in the above design can effectively prevent the instrument on the fixing rod 1 from slipping.

[0027] The specific working method is to completely retract the inner tube 34 into the sleeve 33, then rotate the strip-shaped rotating piece 2 to a position parallel to the fixed rod 1, fix the fixed rods 1 on both sides in the instrument, press the positioning beads 31, and adjust the length of the telescopic rod 3 so that the fixed rod 1 can completely open or clamp the instrument. Then rotate the strip-shaped rotating piece 2 to a position perpendicular to the fixed rod 1 to prevent the instrument from slipping. When the instrument opening is small, completely separate the positioning of the inner tube 34 from the sleeve 33, and then bend the telescopic tube along the bending shaft 32, so that the distance of the fixed rod 1 is further brought closer, so that the fixed rod 1 can extend into and open the instrument with a smaller opening, and then move the strip-shaped rotating piece 2 to a position perpendicular to the fixed rod 1.

[0028] The present application can effectively adjust the distance between the fixed rods 1 by extending and retracting the telescopic rod 3. When the inner tube 34 of the telescopic rod 3 is completely extended out of the sleeve 33, the telescopic rod 3 can be bent by bending the rotating shaft 32, so that the distance between the fixed rods 1 is further shortened, so that the fixed rod 1 can be extended into and open an instrument with a smaller opening, thereby making the U-shaped frame adaptable to more occasions.

[0029] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
