[0002] A nose stripper is a medical device used by medical staff to strip the periosteum in the nasal cavity. It is usually used to strip the nasal periosteum during nasal cosmetic surgery.

[0003] Existing nose peelers usually include a blade and a handle, and the blade is generally fixedly connected to the handle. For example, a nose peeler disclosed in a Chinese utility model patent with authorization announcement number CN 208838095 U lacks protection when not in use, making the exposed blade prone to scratches and other damages, and the exposed blade may cause risks such as scratching the operator. Utility Model Content

[0004] Aiming at the problems existing in the blades of nose strippers in the prior art, a nose stripper is provided.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A nose stripper comprises an outer shell and a blade. The outer shell comprises a handle shell and a blade shell. The interior of the blade shell forms a blade storage chamber, and the end of the blade shell away from the handle shell is provided with a blade entrance and exit connected to the blade storage chamber. The handle shell is provided with a toggle mechanism for connecting with the blade and driving the blade to extend out of or retract into the blade storage chamber through the blade entrance and exit.

[0007] The operator can drive the blade to extend or retract the blade storage cavity by toggling the mechanism, so that the blade can extend from the blade storage cavity during surgery and can be retracted into the blade storage cavity during non-surgery. Since the outer shell provides better protection for the blade retracted into the storage cavity during non-surgery, the probability of damage such as scratches on the blade and the probability of risks such as scratches on the operator by the blade are better reduced during non-surgery.

[0008] Preferably, the toggle mechanism includes a connecting rod disposed in the handle housing and having a length direction consistent with the extension direction of the blade, and also includes a toggle block connected to one end of the connecting rod and extending outside the handle housing, the other end of the connecting rod is connected to the blade, and the toggle block can slide on the handle housing along the length direction of the connecting rod. The toggle block drives the blade to extend or retract into the blade storage cavity through the connecting rod, thereby realizing the extension and retraction operation of the blade.

[0009] Preferably, the outer shell includes an upper shell and a lower shell, the shift block is arranged between the upper shell and the lower shell, the upper shell is provided with a long hole arranged along the sliding direction of the shift block in the length direction, the shift block includes a push block, and the outer side of the push block can fit with the hole wall of the long hole.

The first latch tooth can move upward and engage with the second latch tooth under the elastic force of the spring, and the pushing block can drive the first latch tooth to move downward and separate from the second latch tooth under the action of external force.

[0012] The setting of the shift block limiting mechanism can realize the limiting state of the blade after being extended or retracted. In the limited state, the pushing block moves upward under the action of the spring, so that the first locking tooth and the second locking tooth engage with each other. At this time, the blade is limited and cannot be extended or retracted; when the blade state needs to be changed, the pushing block is pressed downward, so that the first locking tooth moves downward relative to the second locking tooth, and moves to two different horizontal planes with it. At this time, the two are in a disengaged state.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0023] Example 1

[0024] A nose stripper, such as Figures 1-5 As shown, it includes an outer shell 1 and a blade 2, the outer shell 1 includes a handle shell 101 and a blade shell 107, the blade shell 107 has a blade storage chamber 102 formed inside, and the end of the blade shell 107 away from the handle shell 101 is provided with a blade entrance 103 connected to the blade storage chamber 102, and the handle shell 101 is provided with a toggle mechanism 3 for connecting with the blade 2 and driving the blade 2 to extend or retract into the blade storage chamber 102 through the blade entrance 103.

[0025] In this embodiment, the toggle mechanism 3 includes a connecting rod 301 arranged in the handle housing 101 and having a length direction consistent with the extending direction of the blade 2, and also includes a toggle block 302 connected to one end of the connecting rod 301 and extending outside the handle housing 101, and the other end of the connecting rod 301 is connected to the blade 2, and the toggle block 302 can slide on the handle housing 101 along the length direction of the connecting rod 301.

[0026] The outer shell 1 includes an upper shell 104 and a lower shell 105, and the shift block 302 is arranged between the upper shell 104 and the lower shell 105. The upper shell 104 is provided with a long hole 106 arranged in the length direction along the sliding direction of the shift block 302. The shift block 302 includes a pushing block 303, and the outer side surface of the pushing block 303 can fit with the hole wall of the long hole 106. The pushing block 303 also includes an anti-slip pattern 317, and the anti-slip pattern 317 is arranged on the outer end surface of the pushing block 303 extending out of the long hole 106. The setting of the anti-slip pattern 317 better facilitates the operator to push the pushing part to extend and retract the blade 2 into the blade storage cavity 102.

[0027] In this embodiment, the handle housing 101 is also provided with a shift block limiting mechanism, which includes a connecting column 305 connected to the end of the connecting rod 301, and a spring 306 is longitudinally arranged at the connecting column 305 and the upper end of the spring 306 is pressed against the lower surface of the push block 303.

[0028] The shift block limiting mechanism also includes side wings 307 arranged on both sides of the pushing block 303, and the upper end surfaces of the side wings 307 and the outer side surfaces of the pushing block 303 together constitute an L-shaped limiting surface 308. The setting of the L-shaped limiting surface 308 can effectively limit the shift block 302, so that the upper end surface of the upper shell 104 constitutes a limit to the upper end surface of the side wings 307, preventing the shift block 302 from falling out of the upper shell 104 under the elastic force of the spring 306, and the end of the side wing 307 away from the pushing block 303 is provided with a first latch tooth 309, and the inner end surface of the upper shell 104 and located on the edge of the long hole 106 is provided with a second latch tooth 310 that cooperates with the first latch tooth 309. The first latch tooth 309 can move upward under the elastic force of the spring 306 and engage with the second latch tooth 310, and the pushing block 303 can drive the first latch tooth 309 to move downward and separate from the second latch tooth 310 under the action of external force.

[0029] In this embodiment, a first sliding groove 311 is provided on the upper end surface of the lower shell body 105 along the sliding direction of the shift block 302 in the length direction, and a first sliding rail 312 capable of cooperating with the first sliding groove 311 is provided on the lower end surface of the side wing 307. When the first sliding groove 311 and the first sliding rail 312 are slidably engaged, the first latching tooth 309 is separated from the second latching tooth 310.

[0030] The connecting column 305 includes a spring limiting column 313 connected to the end of the connecting rod 301. A sliding column 314 is provided inside the spring limiting column 313. The spring 306 is disposed inside the spring limiting column 313 and sleeved on the sliding column 314. The pushing block 303 is slidably connected to the sliding column 314.

[0031] On the inner end face of the lower housing 105, a second sliding groove 315 is provided with its length direction along the sliding direction of the shifting block 302. The connecting column 305 further includes a sliding plate 304. The spring limiting column 313 is fixed on the upper end face of the sliding plate 304. A second sliding rail 316 that slidably cooperates with the second sliding groove 315 is provided on the lower end face of the sliding plate 304.

[0032] In this embodiment, the outer housing 1 includes an upper housing 104 and a lower housing 105. Scale lines 318 are provided on the upper end face of the upper housing 104 along the length direction of the long hole 106. When the operator pushes the pushing block 303, the blade 2 can be driven to extend or retract from the blade storage cavity 102, so that the blade 2 can extend out of the storage cavity during the operation and retract into the blade storage cavity 102 during the non - operation period. Since the outer housing 1 provides better protection for the blade 2 retracted into the storage cavity during the non - operation period, the probability of scratches and other damages to the blade 2 and the probability of risks such as the blade 2 scratching the operator are preferably reduced during the non - operation period.

[0033] The setting of the shifting - block limiting mechanism can limit the state of the blade 2 after extension or retraction. In the limited state, the pushing block 303 moves upward under the action of the spring 306, so that the first cogs 309 and the second cogs 310 are engaged with each other. At this time, the blade 2 is limited and cannot be extended or retracted; when the state of the blade 2 needs to be changed, the pushing block 303 is pressed downward, so that the first cogs 309 move downward relative to the second cogs 310 and move to two different horizontal planes, and at this time they are in a disengaged state. The staff presses the pushing block 303 and moves the pushing block 303 along the sliding direction at the same time, driving the connecting rod 301 and the blade 2 to move synchronously with the pushing block 303 to drive the blade 2 to extend or retract from the blade storage cavity 102.

[0034] By setting double sliding rails and sliding grooves at the shifting block 302 to guide the sliding of the shifting block 302, it effectively provides the pushing block 303 to drive the connecting rod 301 to realize the stable extension and retraction of the blade 2, preferably guides the moving direction of the pushing block 303, and further increases the stability of the shifting mechanism 3 driving the blade 2 to move;

[0035] During specific use, the blade 2 is located in the blade storage cavity 102 during the non - operation period and extends out of the blade storage cavity 102 during the operation period.

[0036] During the process of performing nasal cosmetic surgery, the difference in the operation process of the nasal dissector compared to the existing common operation process where the blade 2 is directly exposed lies in that the operator needs to drive the blade 2 to extend out of the blade storage cavity 102 before the operation, and after the operation, the operator needs to drive the blade 2 to retract into the storage cavity.

[0037] Specifically, the operator can press the push block 303. After the first tooth 309 moves downward relative to the second tooth 310 and disengages from it, while keeping pressing the push block 303, the operator pushes the push block 303 toward the blade entrance and exit 103 side, so as to drive the blade 2 to extend out of the blade storage cavity 102 through the connecting rod 301. On the contrary, while keeping pressing the push part, the operator pushes the push block 303 away from the blade entrance and exit 103 side, and the blade 2 retracts into the blade storage cavity 102. Furthermore, the outer housing 1 provides better protection for the blade 2 located in the storage cavity. At the same time, after the blade 2 reaches the required state (extended or retracted), the push block 303 is no longer pressed. At this time, the push block 303 moves toward the second tooth 310 under the elastic force of the spring 306, and finally the first tooth 309 and the second tooth 310 are engaged again to realize the limit of the blade 2 in this state.

[0038] In summary, the above description is only the preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the patent of the present invention.
