Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bone wax applicator. Background Technology

[0002] The UBE (unilateral dual-channel endoscopy) technique in minimally invasive spinal surgery has developed rapidly. Its advantages include low cost, short learning curve, and good surgical results, especially solving the challenge of endoscopic treatment of spinal stenosis. During the operation, doctors need to deal with bleeding from the bone surface, and generally choose to use bone wax to apply and stop the bleeding.

[0003] The common method of application is to use surgical instruments such as periosteal elevators or scrapers to apply bone wax to the bleeding point. However, this method has many drawbacks. Because the surface of surgical instruments such as periosteal elevators or scrapers is smooth, the applied bone wax is easy to fall off due to the limited surgical channel or field of vision, making it difficult to apply for hemostasis and delaying the operation time. Especially in UBE surgery, the operating channel is generally a soft tissue channel, which makes it very easy for the bone wax to fall off and not reach the application point for application.

[0004] To address the issue of bone wax easily falling off, various bone wax applicators have emerged. However, most of them work by placing bone wax into a cavity, applying pressure through methods such as pushing to force the wax out of the cavity, and then applying it. While this method solves the problem of bone wax falling off, it is cumbersome to operate, difficult to apply, and leaves residual bone wax in the cavity, leading to waste. Utility Model Content

[0005] To address the problems in the background art, prevent the bone wax to be applied from falling off, and improve the application effect, this utility model proposes a bone wax applicator, including a handle, a connecting rod, and an application head. The handle is fixedly connected to the connecting rod, and the application head is located at the end of the connecting rod away from the handle. At least one application head is provided, and the application head is provided with a rough surface.

[0006] Preferably, the axis of the applicator head is collinear with the axis of the connecting rod, or there is an angle between the axis of the applicator head and the axis of the connecting rod.

[0007] Preferably, one side of the applicator head is provided with a rough surface;

[0008] Alternatively, rough surfaces are provided on both sides of the applicator head, and the rough surfaces on both sides of the applicator head are symmetrically distributed;

[0009] Alternatively, the periphery of the applicator head may have a rough surface.

[0010] Preferably, the applicator head is spherical or hemispherical, and the rough surface is provided on the curved outer wall of the applicator head.

[0011] Preferably, the rough surface includes multiple dot-shaped protrusions or multiple block-shaped protrusions, which are spaced apart on the curved outer wall of the applicator head.

[0012] Preferably, one side or both symmetrical sides of the applicator head are planar, and the rough surface is provided on the planar surface;

[0013] The plane length direction is set along the axis of the applicator head, or the plane length direction is set obliquely upward from the end of the applicator head away from the connecting rod along the axis of the applicator head.

[0014] Preferably, the rough surface includes a plurality of strip-shaped protrusions spaced apart along the length direction of the plane, the length direction of the strip-shaped protrusions being parallel to the radial direction of the applicator head.

[0015] Preferably, the width of the top surface of the strip-shaped protrusion is smaller than the width of the bottom surface of the strip-shaped protrusion, or the width of the top surface of the strip-shaped protrusion is larger than the width of the bottom surface of the strip-shaped protrusion.

[0016] Preferably, the applicator head is columnar, and the rough surface is located on the periphery of the applicator head.

[0017] Preferably, the rough surface includes threaded protrusions arranged along the periphery of the applicator head.

[0018] The beneficial effects of this utility model are as follows:

[0019] The applicator head of this invention has a roughened surface, which improves the adhesion of bone wax and prevents it from falling off before entering the working area or during application. Simultaneously, the applicator head is moved by a connecting rod to perform the application action, making the process simple and easy to operate. Furthermore, different applicator head designs are suitable for different types of bone surface bleeding; different head designs allow for different application methods and amounts of bone wax. Selecting the appropriate applicator head based on the size of the bleeding surface effectively improves bone wax utilization and provides a better application result. Attached Figure Description

[0028] Example 1

[0029] Combined with appendix Figure 1 - Appendix Figure 3 The present invention provides a bone wax applicator in embodiment 1, comprising a handle 1, a connecting rod 2 and an applicator head 3. The handle 1 is fixedly connected to the connecting rod 2, and the applicator head 3 is disposed at the end of the connecting rod 2 away from the handle 1. At least one applicator head 3 is provided, and the applicator head 3 is provided with a rough surface.

[0030] In use, bone wax is placed on the rough surface of the application head 3. The user holds the handle 1 and moves the application head 3, coated with bone wax, to the area to be applied. The length of the connecting rod 2 determines the working length of the application head 3.

[0031] There may be one or two application heads 3. When there are two application heads 3, a connecting rod 2 is fixed to each end of the handle 1.

[0032] Specifically, the axis of the applicator 3 is collinear with the axis of the connecting rod 2, or there is an angle between the axis of the applicator 3 and the axis of the connecting rod. That is, the applicator 3 and the connecting rod 2 are on the same straight line, or the applicator 3 is bent relative to the connecting rod 2.

[0033] Specifically, one side of the applicator head 3 is provided with a rough surface;

[0034] Alternatively, rough surfaces are provided on both sides of the applicator head 3, and the rough surfaces on both sides of the applicator head 3 are symmetrically distributed;

[0035] Alternatively, the periphery of the applicator head 3 may have a rough surface.

[0036] Specifically, the applicator head 3 is spherical or hemispherical, and the rough surface is provided on the curved outer wall of the applicator head 3. More specifically, the rough surface includes a plurality of dot-shaped protrusions, which are spaced apart on the curved outer wall of the applicator head 3, that is, the outer wall of the curved surface of the applicator head 3 is frosted; or the rough surface includes a plurality of block-shaped protrusions, which are spaced apart on the curved outer wall of the applicator head 3.

[0037] When the applicator head 3 is spherical or hemispherical, it is suitable for situations where the bleeding area is small and the bleeding point is easy to find. When applying the applicator head 3, the applicator should rotate around the axis of the applicator head 3.

[0038] Example 2

[0040] The plane length direction is set along the axis of the applicator head 3, or the plane length direction is set obliquely upward from the end of the applicator head 3 away from the connecting rod 2 along the axis of the applicator head 3.

[0041] Specifically, the rough surface includes a plurality of strip-shaped protrusions spaced apart along the length of the plane, the length direction of which is parallel to the radial direction of the applicator head 3.

[0042] When the plane is not parallel to the connecting rod axis, the width of the top surface of the strip-shaped protrusion is smaller than the width of the bottom surface of the strip-shaped protrusion. That is, the strip-shaped protrusion is trapezoidal, the top surface of the strip-shaped protrusion is the end of the strip-shaped protrusion away from the applicator head 3, and the bottom surface of the strip-shaped protrusion is the end of the strip-shaped protrusion connected to the plane of the applicator head 3.

[0043] When the plane is parallel to the axis of the connecting rod, the width of the top surface of the strip-shaped protrusion is greater than the width of the bottom surface of the strip-shaped protrusion, that is, the strip-shaped protrusion is inverted trapezoidal.

[0044] The rough surface of this embodiment is suitable for situations with large bleeding areas and large application areas. When applying, the application head 3 is pulled to apply the product.

[0045] Example 3

[0046] Combined with appendix Figure 5 This invention provides a bone wax applicator in Embodiment 3. The basic structural properties of the bone wax applicator in this embodiment are consistent with those in Embodiment 1. The difference is that the applicator head 3 in this embodiment is columnar, and the rough surface is located on the periphery of the applicator head 3. Specifically, the rough surface includes threaded protrusions arranged along the periphery of the applicator head 3.

[0047] The applicator head 3 in this embodiment is suitable for situations where there are multiple bleeding points and it is difficult to determine the specific location of the bleeding points.
