[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all.
[0027] Embodiment 1: refer to Figures 1-4 A working sleeve device, comprising: a working sleeve main body, a probe hook main body and a push assembly.
[0028] In this embodiment, the working sleeve main body is composed of a connecting portion main body 1 and a front mirror tube 2. The front mirror tube 2 is fixedly installed at one end of the connecting portion main body 1 and is in communication with the inside of the connecting portion main body 1. The outer wall of the front mirror tube 2 is fixedly sleeved with a fixed baffle 3, and the fixed baffle 3 is used to provide additional support for the equipment.
[0029] In this embodiment, the design of the probe hook main body 5 is one of the key parts. A through hole 4 is formed in the inner wall of the front mirror tube 2, and one end of the through hole 4 extends to the inside of the connecting portion main body 1. The probe hook main body 5 is in sliding fit with the inner wall of the through hole 4, so that the probe hook main body 5 can move freely in the through hole 4. The probe hook main body 5 is made of carbon fiber material, and its main function is to bluntly separate and protect the nerve root during the operation. In order to realize this function, the end of the probe hook main body 5 away from the connecting portion main body 1 is provided with an inclination of 10 to 15 degrees. Such design helps better contact and separate the nerve root, while reducing damage to the surrounding tissue.
[0030] In this embodiment, the design of the push assembly is used to drive the probe hook main body 5 to move stably. Specifically, the push assembly comprises an adjusting groove 7 formed in the outer wall of the connecting portion main body 1. The adjusting groove 7 is in communication with the through hole 4 in the inside of the connecting portion main body 1, so that one end of the probe hook main body 5 can be bent into L type and penetrate through the adjusting groove 7. One end of the probe hook main body 5 is fixedly installed with a moving lever 6, and the setting of the moving lever 6 facilitates the pushing of the probe hook main body 5 from the outside.
[0031] In order to further improve the stability of the movement of the probe body 5, in the embodiment, the pushing assembly further comprises a fixed rod 8 fixedly connected with the outer wall of the connecting part body 1 through a support. One end of the fixed rod 8 is slidably penetrated through the moving lever 6, which can ensure the stability of the moving lever 6 during movement. The outer wall of the fixed rod 8 is sleeved with a spring 9, one end of the spring 9 is fixedly connected with the outer wall of the fixed rod 8, and the other end is fixedly connected with one side of the moving lever 6. The spring 9 is arranged to realize the rapid resetting of the probe body 5. When the moving lever 6 is pushed by external force, the spring 9 will be compressed, and when the external force disappears, the spring 9 will release energy to reset the moving lever 6 and the probe body 5.
[0032] The present application can be used in the field of medical equipment technology, and can also be used in other fields applicable to the present application.
[0033] Embodiment 2: Reference Figure 4 On the basis of improving embodiment 1: a working sleeve device containing a protective and passive separation nerve root probe is applied to the field of medical equipment technology;
[0034] In the embodiment, the outer wall of the connecting part body 1 is further fixedly provided with a fixed plate 10, and the fixed plate 10 is sleeved on the outer wall of the fixed rod 8. The outer wall of the fixed rod 8 is sleeved with an abutting sleeve 11, and the abutting sleeve 11 is in sliding fit with the outer wall of the fixed rod 8. The outer wall of the abutting sleeve 11 is provided with a thread, and is threadedly connected with the fixed plate 10. Such design makes the abutting sleeve 11 moveable on the fixed rod 8, and realizes accurate movement through the thread connection with the fixed plate 10. One end of the abutting sleeve 11 cooperates with the moving lever 6, which is used to abut the moving lever 6 and complete the positioning of the moving lever 6. In this way, the position of the abutting sleeve 11 can be adjusted as needed, so as to determine the extension length of the probe body 5.
[0035] In order to facilitate the turning of the abutting sleeve 11, the outer wall of the abutting sleeve 11 is further fixedly sleeved with a turning ring 12. The turning ring 12 makes it convenient for medical staff to turn the abutting sleeve 11 by fingers, so as to realize the adjustment of the position.
[0036] The working principle and use process of the technical solution are as follows: when the user uses the working sleeve to perform surgical operation, after the current mirror tube 2 is inserted into the nerve root position of the patient, the user can push the moving lever 6 to complete the pushing out of the probe body 5, the probe body 5 is designed to be inclined at one end, can bluntly separate the nerve root, and is beneficial to continuously provide protection for the nerve root during the operation; when the user needs to push out the probe body 5 more accurately, at this time, the user can externally push the dial ring 12, the dial ring 12 can drive the abutting sleeve 11 to rotate, under the cooperation of the abutting sleeve 11 and the fixed plate 10, the abutting sleeve 11 can slowly move along the fixed rod 8, thereby pushing the moving lever 6 to move synchronously, and then the accurate pushing out of the probe body 5 can be realized; the spring 9 can continuously abut the moving lever 6 to make it closely adhere to one end of the abutting sleeve 11 when the probe body 5 is pushed out, and can ensure the stable movement of the probe body 5, and the spring 9 can also assist in automatically retracting the probe body 5 after the surgical operation is completed, and can ensure the stable storage of the probe body 5.
[0037] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered in the protection scope of the present application.
