Description

Technical Field

[0001] This utility model relates to a medical device, specifically a protective sleeve for the reamer during surgery of a femoral neck dynamic cross nail system. Background Technology

[0002] The femoral neck system (FNS) is a novel internal fixation system for the femoral neck, consisting of a dynamic rod, anti-rotation screws, and a bone plate. During operation, this system requires reaming the hole along the central guide pin using a reamer. However, the original kit lacks a protective sleeve for the reamer, leading to severe damage to the skin and soft tissues during surgery. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a protective sleeve for the reamer during surgery in a femoral neck dynamic cross screw system. This sleeve can effectively protect the skin and soft tissue during reaming, and the reaming depth can be clearly observed through the observation hole on the protective sleeve, increasing surgical precision.

[0004] To achieve the above objectives, this utility model provides a protective sleeve for the reamer during surgery in a femoral neck dynamic cross screw system. The sleeve includes a handle, a handle base, a sleeve body, observation holes, scale lines, and a depth measuring gauge. The handle base is fixedly connected to the end of the handle, and the handle base is fixedly connected to the upper end of the sleeve body. Multiple observation holes are evenly distributed on the side of the sleeve body. The observation holes arranged along the axis of the sleeve body form a row, and the spacing between each row of observation holes is five to fifteen millimeters.

[0005] In addition, the protective sleeve for the reamer during surgery of the femoral neck dynamic cross nail system proposed in the above embodiments of this utility model may also have the following additional technical features:

[0006] As a further improvement of this utility model, the observation hole is an oblong hole.

[0007] As a further improvement of this utility model, the surface of the sleeve body next to the observation hole is provided with scale lines.

[0008] As a further improvement of this utility model, a recessed hole is provided on the upper surface of the handle base, the recessed hole extends to the bottom of the sleeve body, a depth measuring ruler is inserted into the recessed hole, and the surface of the depth measuring ruler is provided with graduations.

[0009] As a further improvement of this utility model, the outer end of the depth measuring gauge is provided with a spherical end.

[0010] By means of the above solution, this utility model has at least the following advantages: compared with conventional guide sleeves, by adding an observation hole and a depth measuring gauge to the sleeve body, surgical efficiency can be effectively improved and surgical safety can be ensured. The skin and soft tissue can be effectively protected during hole enlargement. At the same time, the hole enlargement depth of the enlargement drill can be clearly observed through the observation hole on the hole enlargement protective sleeve, increasing the accuracy of the surgery.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, in the description of this specification, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] The following description, in conjunction with the accompanying drawings, describes the protective sleeve for the reamer during surgery in the femoral neck dynamic cross nail system of this utility model.

[0019] In Embodiment 1 of this application, as Figure 1 and Figure 2 As shown, this invention relates to a protective sleeve for a reamer used in a femoral neck dynamic cross screw system (hereinafter referred to as "the invention"). It includes a handle 1, a handle base 2, a sleeve body 3, observation holes 4, scale lines 5, and a depth gauge 6. The handle 1 is fixedly connected to the handle base 2 at one end, and the handle base 2 is fixedly connected to the upper end of the sleeve body 3. Multiple observation holes 4 are evenly distributed along the side of the sleeve body 3, arranged in a row along the axis of the sleeve body 3, with a spacing of five to fifteen millimeters between each row of observation holes 4. To further reduce obstruction and facilitate observation of the reamer by medical personnel, the observation holes 4 are oblong. For reference by medical personnel, scale lines 5 are provided on the surface of the sleeve body 3 next to the observation holes 4.

[0020] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 3 As shown, a recessed hole is formed on the upper surface of the handle base 2, extending to the bottom of the sleeve body 3. A depth gauge 6 is inserted into the recessed hole, and the surface of the depth gauge 6 is marked with graduations. The added depth gauge 6 allows medical personnel to understand the depth status of the reamer.

[0021] To further optimize the working efficiency of this application and facilitate medical staff in controlling the depth measuring gauge 6, the outer end of the depth measuring gauge 6 is provided with a spherical end. A threaded knob is provided on the outside of the handle base 2 for locking the depth measuring gauge 6.

[0022] When using a femoral neck dynamic cross nail system, install and sterilize the protective sleeve of the reamer during surgery, and the equipment is ready for use.

[0023] When this utility model is used, its specific operation is as follows:

[0024] In use, the staff inserts the sleeve body 3 into the open window, then adjusts the angle and the exposed length of the depth gauge 6 according to the required reamer depth. Medical personnel can then begin drilling with the reamer. They can observe the reamer's operation and drilling depth through the observation hole 4 and scale lines 5. When the reamer reaches the set position, the reamer drill base is flush with the end of the depth gauge 6, indicating that drilling is complete. The depth gauge 6 has a limiting block at one end inside the sleeve body 3, and a groove is formed on the inner wall of the recessed hole in the sleeve body 3 where the depth gauge 6 is installed, allowing the limiting block to slide.

[0025] In summary, the femoral neck dynamic cross screw system surgical reamer protective sleeve of this utility model, by adding an observation hole 4 and a depth measuring gauge 6 to the sleeve body 3, can timely understand the depth of incision during surgery, which can effectively improve surgical efficiency and ensure surgical safety.
