Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel nerve stripper. Background Art

[0002] A nerve stripper is an instrument used for nerve dissection and protection during surgery. It exposes the nerve and maintains its integrity by gently stripping the surrounding tissue. Its characteristics are as follows: The nerve stripper is usually made of stainless steel or titanium alloy, with good corrosion resistance and rigidity. Its unique design can easily strip the tissue around the nerve while minimizing damage to the nerve. Moreover, the nerve stripper is usually composed of a handle and a stripping head. The handle part is generally ergonomically designed, easy to hold and operate. The stripping head part is usually flat with rounded edges to ensure that the nerve is not cut or squeezed during stripping. In addition, according to different surgical needs, nerve strippers can be divided into many types. Common types include straight type, curved type and angle adjustable type. The straight nerve stripper is suitable for straight cutting and stripping, the curved type is suitable for surgery that requires stripping on a curved path, and the angle adjustable type can flexibly adjust the angle according to surgical needs. In short, the nerve stripper is a commonly used orthopedic surgical instrument for nerve dissection and protection. It has good corrosion resistance and rigidity, unique design and easy operation.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The utility model provides a new type of nerve stripper, please refer to Figure 1-Figure 4 , comprising a handle, one end of which is detachably connected to a connecting column 30 through a connecting assembly, and one end of the connecting column 30 is fixedly mounted with a stripping sub-body 31;

[0038] The handle includes: a first hand-held plate 10, a storage slot 11, a second hand-held plate 12, a slide slot 40, a slide rod 41, a round plate 42, a lifting plate 43, a spring 44, a slider 45, a support block 46, a limit block 47, a limit slot 48, and a groove;

[0039] The storage groove 11 is opened in the first hand-held plate 10, and the second hand-held plate 12 is slidably connected to the storage groove 11. A slide groove 40 is opened at the top of the first hand-held plate 10, and the slide groove 40 is connected to the storage groove 11. A slide rod 41 is slidably connected in the slide groove 40. In addition, the slide groove 40 is capable of limiting the position of the slide rod 41 to avoid the first hand-held plate 10 and the second hand-held plate 12 from separating. A circular plate 42 is fixedly installed on the top of the slide rod 41, and the circular plate 42 has the function of contacting with the fingers of a person so that the person can squeeze the circular plate 42. A lifting plate 43 is fixedly installed at the bottom of the slide rod 41. When the circular plate 42 is squeezed, the slide rod 41 has the function of descending. The function is that when the slide bar 41 descends, it has the function of driving the lifting plate 43 to descend. A groove is provided at the top of the second hand-held plate 12, and the lifting plate 43 is inserted in the groove. The slider 45 is fixedly installed in the groove. A plurality of springs 44 are fixedly installed between the lifting plate 43 and the slider 45. Support blocks 46 are fixedly installed at both ends of the top of the lifting plate 43. The limit block 47 is fixedly installed on the top of the support block 46. A plurality of limit grooves 48 are provided on the first hand-held plate 10 located at the top of the storage groove 11, and the plurality of limit grooves 48 are connected. The limit block 47 is inserted in a group of limit grooves 48, wherein the shape of the limit block 47 is set to be hemispherical, and the shape of the limit groove 48 is also set to be hemispherical.

[0040] The connecting assembly comprises: a thread groove 20 and a stud 21;

[0041] The thread groove 20 is provided at one end of the second hand-held plate 12, and one end of the stud 21 is fixedly mounted on the connecting post 30, and the stud 21 is threadedly connected in the thread groove 20. When a stripping sub-body 31 of a different shape is required, the corresponding stripping sub-body 31 is first selected, and then the connecting post 30 is rotated. When the connecting post 30 rotates, the stud 21 is driven to rotate until the stud 21 is threadedly connected in the thread groove 20, and the stripping sub-body 31 can be installed.

[0042] Working principle: when the length of the handle needs to be adjusted, first press the circular plate 42 with the thumb, at this time, the circular plate 42 will move toward the first hand-held plate 10, and when the circular plate 42 moves toward the first hand-held plate 10, its slide bar 41 will descend, and when the slide bar 41 descends, it will drive the lifting plate 43 to descend, and when the lifting plate 43 descends, it will squeeze the spring 44 to deform the spring 44, and at the same time, the descending lifting plate 43 will drive the support block 46 to descend, and when the support block 46 descends, the limit block 47 and the limit groove 48 will be separated, and when the limit block 47 and the limit groove 48 are separated, the personnel can use the thumb to push the circular plate 42 to move, and when the circular plate 42 moves, it will drive the slide bar 41 moves, and when the slide bar 41 moves, it will drive the lifting plate 43 to move. When the lifting plate 43 moves, the slider 45 will move through the spring 44. At the same time, the moved lifting plate 43 and the slider 45 will squeeze the groove to make the second hand-held plate 12 move in the storage groove 11. In addition, when the lifting plate 43 moves, it will drive the limit block 47 to move. When the first hand-held plate 10 and the second hand-held plate 12 are at a suitable length, the circular plate 42 can be released so that the circular plate 42 can be restored to its original position under the elastic force of the spring 44. At this time, the limit block 47 will be inserted into a set of limit grooves 48 to limit the position of the second hand-held plate 12. At this point, the length of the handle can be adjusted.

[0043] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
