[0025] 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, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model provides two technical solutions:

[0027] Figure 1 The first embodiment is shown: the length of the septum surgery blade protection structure can be pre-adjusted, including the silica gel film sleeve 2 set outside the surgical blade 1, in addition to using medical silica gel material, the silica gel film sleeve 2 can also use other non-toxic harmless similar high elasticity material, the silica gel film sleeve 2 is elastically covered and attached to the outside of the surgical blade 1, the silica gel film sleeve 2 is cut into different lengths by the end to expose different lengths of the surgical blade 1 to carry out cutting operation, the two sides of the cutting end of the silica gel film sleeve 2 are provided with scale lines 21, the two sides of the surgical blade 1 are provided with convex edges, the two sides of the silica gel film sleeve 2 are provided with long slots 22 corresponding to the positions of the convex edges.

[0028] The blade protection structure is a sheath-like structure made of silica gel, which can be nested on the blade. The material is thin, tough and soft, which can protect the nasal cavity structure and will not affect the normal operation, effectively avoiding secondary damage. The front part of the protection device is consistent with the shape of the No. 15 blade, and the tip has a scale line 21. Different lengths can be cut according to the needs of the operator to determine the exposure length of the blade tip. The rear part is consistent with the shape of the handle clamping groove, which ensures that the device has good fit and will not fall off or dislocate during the operation.

[0029] Figures 2-5 The second embodiment is shown, and the main difference from the first embodiment is that the silica gel film sleeve 2 can be directly coated on the surface of the surgical blade 1 during production, or the length-adjustable septum surgery blade protection structure installation tool is used for on-site installation before use.

[0030] The length-adjustable septum surgery blade protection structure installation tool includes an internal support structure 3 for supporting the silica gel film sleeve 2, and a cutting structure 4 for cutting the silica gel film sleeve 2. The cutting structure 4 is used to push the silica gel film sleeve 2 to completely wrap the surgical blade 1 when the silica gel film sleeve 2 is installed.

[0031] The internal support structure 3 includes two internal recessed strips 31, and the internal recessed strip 31 is provided with a recess on one side for sleeving the edge of the surgical blade 1. The internal recessed strip 31 is arranged between the surgical blade 1 and the silica gel film sleeve 2, so that when the surgical blade 1 is inserted, the silica gel film sleeve 2 is supported by the internal recessed strip 31. The end of the internal recessed strip 31 located outside the silica gel film sleeve 2 is provided with a protrusion 32 on both sides. The protrusion 32 is provided to facilitate the pulling out of the internal recessed strip 31.

[0032] The cutting structure 4 includes two clamping pieces 41, and the two clamping pieces 41 are connected by a hinge to form a scissors type on the side surface. The hinge has a gap with a distance greater than the width of the surgical blade 1. The clamping piece 41 is provided with a cutting blade 42 at one end. The clamping piece 41 is provided with an arch 43 adapted to the protruding rib at the other side of the hinge. The clamping piece 41 is provided with a non-slip piece 44 on the inner side and on both sides of the arch 43 for clamping the silica gel film sleeve 2 and increasing the friction. The inner side of the non-slip piece 44 is provided with a non-slip pattern.

[0033] By setting the internal support structure 3 to support the silica gel film sleeve 2 on the inner side, it is convenient to insert the surgical blade 1. During the insertion process, the blade edge can avoid cutting the silica gel film sleeve 2. After pulling out the internal support structure 3, the silica gel film sleeve 2 automatically rebounds and can be perfectly shrunk and attached to the surgical blade 1. In combination with the cutting structure 4, the silica gel film sleeve 2 can be clamped and set by using the cutting structure 4 when the silica gel film sleeve 2 is set, which can play a non-slip effect and facilitate the setting operation of the thin silica gel film sleeve 2. The cutting blade 42 at the other end of the cutting structure 4 can also be used for neat cutting of the silica gel film sleeve 2, which is convenient and fast.

[0034] Meanwhile, the contents not described in detail in the present specification are all the prior art known to those skilled in the art.

[0035] In the process of setting the silicone membrane sleeve 2, first, insert the two inner recessed strips 31 into the two sides of the silicone membrane sleeve 2, then align the upper and lower edges of the surgical blade 1 with the inner recessed grooves of the inner recessed strips 31 and insert them, so that the surgical blade 1 can expand the two inner recessed strips 31 and indirectly expand the silicone membrane sleeve 2, after inserting a part, clamp the silicone membrane sleeve 2 with one side of the cutting structure 4, use the anti-slip piece 44 to clamp the silicone membrane sleeve 2 to increase the friction, then use the cutting structure 4 to push the silicone membrane sleeve 2 to completely cover the surgical blade 1, then pull out the inner recessed strips 31, and the silicone membrane sleeve 2 can be perfectly shrunk and attached to the surgical blade 1.

[0036] Before using the surgical blade 1, clamp the cutting blade 42 of the other end of the cutting structure 4 to the appropriate position of the scale line 21 on the silicone membrane sleeve 2, cut and break the silicone membrane sleeve 2, so that the surgical blade 1 exposes a part of the blade tip, and then it can be used for surgery after sterilization.

[0037] It should be noted that in the present text, relational terms such as first and second are used merely to distinguish one entity or action from another, without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus including a series of elements includes not only those elements, but also other elements not explicitly listed or inherent to such a process, method, article or apparatus.
