DETAILED DESCRIPTION

[0025] 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.

[0026] The utility model provides Figure 1-Figure 4 The auxiliary lifting device for lumbar puncture shown comprises:

[0027] A positioning frame 1, wherein two symmetrically distributed arm supports 11 are installed at the bottom end of the positioning frame 1, and a retractable telescopic rod 12 is installed at the bottom end of the two arm supports 11 and the positioning frame 1;

[0028] Two lifting assemblies 2 are used to extend the arm support 11. Each lifting assembly 2 includes a rotating groove 21 opened on the top of the arm support 11 and a shaft rod 24 rotatably installed in the rotating groove 21. The outside of the shaft rod 24 is sleeved with an ear plate 22, and one side of the ear plate 22 extends to the outside of the rotating groove 21 and is fixed with a support plate 23. The arm support 11 is provided with a locking assembly for fixing the shaft rod 24, and the locking assembly is provided with an interference assembly 3 for stabilizing it.

[0029] The locking assembly includes a slide groove opened on one side of the arm support 11 and a plug-in block 27 fixed in the shaft 24. A plug-in ring 25 is slidably connected in the slide groove, and the plug-in ring 25 and the shaft 24 are plugged and fixed. The outside of the plug-in ring 25 is provided with a plurality of clamping grooves 26 for inserting the plug-in block 27. A pulling assembly for pulling the plug-in ring 25 to move is provided on the arm support 11.

[0030] The pulling assembly includes a connecting rod 28 fixed to one end of the plug ring 25, and the connecting rod 28 is slidably connected to the slide groove. A plug-in ear 29 is inserted on the arm support 11, and one end of the plug-in ear 29 is inserted into the slide groove and fixed to one end of the connecting rod 28.

[0031] Before the patient is punctured, the patient's body is first placed close to the edge of the bed, and the positioning frame 1 is moved to the back of the doctor, and the doctor is located between the two arm supports 11. The arm supports 11 and the positioning frame 1 are adjusted in height through the telescopic rod 12 to maintain a good match between them, so that the doctor can be surrounded from behind, and the plug-in ear 29 is pulled to slide along the slide groove, and then the plug-in ear 29 moves to pull the connecting rod 28 along the slide groove. At this time, the plug ring 25 is disengaged from the shaft rod 24, that is, the plug-in block 27 is disengaged from one of the clamping grooves 26, and the support plate 23 is pulled to drive the ear plate 22 and the shaft rod 24 to rotate along the rotation groove 21, that is, the shaft rod 24 and the arm support 11 keep rotating, and the support plate 23 and the ear plate 22 rotate to keep level with the arm support 11, so that the support plate 2 3 is used to extend one side of the arm support 11. As the plug-in ear 29 is pushed, the connecting rod 28 is driven to slide along the slide groove, and the plug ring 25 is reinserted into the shaft rod 24. Then the plug-in block 27 is plugged and fixed with another clamping groove 26, and it is limited under the action of the resistance component 3. Then, one end of the arm support 11 is close to the edge of the bed, and the doctor is in a half-squatting position close to the edge of the bed, and the elbow joint and part of the forearm are placed on the arm support 11 and the support plate 23 to assist in lifting the doctor's elbow joint and part of the forearm, increase the stability of the doctor's elbow joint and part of the forearm, and help the doctor to freely adjust the direction on the arm support 11 and the support plate 23 as the forearm moves, which can assist the doctor in performing stable puncture on the patient and avoid secondary injury to the patient, thereby improving the safety of the patient's puncture and facilitating operation.

[0032] Furthermore, a storage cavity for accommodating the support plate 23 is provided at the bottom of the arm rest 11, and the storage cavity is communicated with the interior of the rotating groove 21; based on this, through the setting of the storage cavity, the support plate 23 can be stored when not in use, which can improve the rational use of the space on the arm rest 11 and facilitate the support plate 23 to be folded and used according to needs.

[0033] In addition, refer to Figure 1-Figure 4 As shown, the abutment assembly 3 includes a moving cavity 33 provided in the slide groove and a positioning ring 31 sleeved on the outside of the connecting rod 28, and the positioning ring 31 is located in the moving cavity 33, a connecting ring 32 is fixed in the moving cavity 33, and the connecting ring 32 is sleeved on the outside of the connecting rod 28, and a spring 34 is fixed between the connecting ring 32 and the positioning ring 31.

[0034] Through the above technical solution:

[0035] When the insert ring 25 is inserted into the shaft 24, the elasticity of the spring 34 and the reset thrust will immediately give a thrust to one side of the positioning ring 31. At this time, one end of the positioning ring 31 will contact with one end of the shaft 24, and the insert ring 25 will be stably contacted in the shaft 24. The spring 34 will generate a reaction force on the insert ring 25, which can provide additional stability for the insert ring 25, so as to achieve a stable connection between the shaft 24 and the arm support 11, ensure that the shaft 24 is fixed in the required position, avoid the shaft 24 from moving during use, effectively improve the stability of the shaft 24, and further improve the safety of patient puncture.

[0036] Furthermore, a limiting column 35 is fixed to the outside of the positioning ring 31, and a limiting groove 36 for the limiting column 35 to slide is opened in the movable cavity 33, and one end of the limiting column 35 passes through the connecting ring 32 and extends into the limiting groove 36; based on this, through the setting of the limiting column 35, it is possible to achieve a limiting effect on the positioning ring 31 in the movable cavity 33, thereby preventing the positioning ring 31 from rotating in the movable cavity 33, and at the same time, the positioning ring 31 is guided to move along the movable cavity 33, thereby further improving the stability of the positioning ring 31 in the movable cavity 33.

[0037] Furthermore, a rotating disk 37 is fixed to one end of the plug-in ear 29, and an anti-slip roller is fixed to the outside of the rotating disk 37; based on this, through the setting of the rotating disk 37, a larger force-bearing area can be formed with the doctor's hand, so that the user can apply force more easily when holding it, so that the plug-in ear 29 can be pulled stably, thereby achieving the purpose of speeding up the assembly or disassembly operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
