[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this invention is to provide an external auditory canal shaving razor to solve the problems existing in the prior art. By setting the blade body into different sections and offsetting the blade head and handle, the razor head can be avoided from being obstructed by the handle and hand, thus providing an open view for shaving the hair inside the external auditory canal.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-4 As shown, this utility model provides an external auditory canal razor, mainly used for shaving hair inside the external auditory canal during surgery. The external auditory canal razor includes a head 1, a handle 3, and a blade 2. The head 1 is equipped with a blade 5. By inserting the head 1 into the external auditory canal, the blade 5 is used to shave the hair. The blade 2 is a structure connecting the head 1 and the handle 3, used to extend the length of the external auditory canal razor, so that the head 1 can be smoothly inserted into the external auditory canal by holding the handle 3. The blade 2 includes a first section 21, a second section 22, and a third section 23 connected in sequence. The second section 22 connects the first section 21 and the third section 23. With the support of the second section 22, the axis of the first section 21 and the axis of the third section 23 are spaced apart, forming an offset structure. The first section 21 is coaxially connected to the head 1, and the third section 23 is coaxially connected to the handle 3, thereby making the head 1 and the handle 3 form an offset structure. The handle 3 is for hand-held use, allowing the operator to perform shaving.

[0034] This invention sets the blade body 2 into different segments to offset the blade head 1 and the handle 3, which can avoid the handle 3 and the hand from obstructing the blade head 1, providing an open field of vision for the blade head 1 to shave in the external auditory canal, maintaining sufficient operational convenience and shaving efficiency, and meeting the actual needs of ear surgery.

[0035] In one embodiment, the shaving head 1 further includes a housing 13, and the blade 5 is disposed within the housing 13. Specifically, the blade 5 can be fixed within the housing 13 during its molding process, eliminating the need for subsequent installation, thus saving on structural design and installation costs, and allowing for single-use application. The blade 5 has a cutting edge 51, the extension direction of which is parallel to the axial direction of the shaving head 1. An opening 12 is provided on the side of the housing 13 for the cutting edge 51 to protrude. With the above arrangement, the extension direction of the cutting edge 51 is the same as the depth direction of the external auditory canal. Therefore, when the cutting edge 51 is working, it can move along the inner arc direction of the external auditory canal, better conforming to the inner wall of the external auditory canal and ensuring shaving efficiency.

[0036] In one embodiment, the openings 12 are spaced apart along the extension direction of the blade 51. On the one hand, the blade 51 exposed in the openings 12 can be used for shaving, and on the other hand, the structure between adjacent openings 12 can be used to form a protective barrier. In this way, the position of the blade 5 can be constrained and the blade 51 can be prevented from directly contacting the skin inside the external auditory canal and causing scratches to the skin.

[0037] In one embodiment, the radial cross-section of the outer shell 13 is teardrop-shaped, with an arc end and a pointed end. The blade 51 can be located at the pointed end of the teardrop shape. The arc end can better fit the inner wall of the external auditory canal, ensuring that the blade head 1 can move smoothly within the external auditory canal, while avoiding damage to the non-shaving area caused by the blade 51.

[0038] In one embodiment, the first section 21, the second section 22, and the third section 23 are located on the same blade plane, and the blade 51 is perpendicular to the blade plane. Thus, the line connecting the handle 3 and the blade head 1 is perpendicular to the line connecting the blade 51 and the blade head 1, forming a mutually perpendicular structure, which facilitates shaving hair inside the ear canal and improves ease of use.

[0039] In one embodiment, the first body segment 21, the second body segment 22, and the third body segment 23 form a hollow first tubular structure, and the handle 3 is a hollow second tubular structure. The outer shell 13, the first tubular structure, and the second tubular structure are sequentially connected. The outer shell 13 is provided with a window 11, and the second tubular structure is used to connect to the suction device. Under the negative pressure suction of the suction device, the shaved ear hair can enter the interior of the outer shell 13 through the window 11, and then be collected by the suction device sequentially through the first tubular structure and the second tubular structure, thus preventing ear hair from falling out and affecting the surrounding environment and the environment inside the ear canal.

[0040] In one embodiment, the window 11 may be provided only on one side of the blade 5, such as... Figure 1 The top or bottom shown can also be on both sides of the blade 5 (i.e.) Figure 1 Both the top and bottom sides (as shown) are configured.

[0041] In one embodiment, the window 11 can be set as a rectangle with a length of 1.5mm to 2.5mm and a width of 2.5mm to 3.5mm, for example, using a size of 2mm × 3mm.

[0042] In one embodiment, the blade 5 can be set as a rectangle with a length of 8mm to 12mm and a width of 3mm to 6mm, for example, a size of 10mm × 5mm.

[0043] In one embodiment, the device further includes a pipe interface 4 connected to the second tubular structure. The pipe interface 4 includes hollow frustums 41 connected axially. The end of the hollow frustums 41 away from the second tubular structure is a small-diameter end, which facilitates the insertion of the connecting pipe of the suction device. An annular groove 42 is formed between the hollow frustums 41. After the connecting pipe is inserted, the elasticity of the pipe wall of the connecting pipe can be used to lock it in place at the position of the annular groove 42, reducing the risk of the connecting pipe and the pipe interface 4 becoming detached.

[0044] In one embodiment, the radial cross-section of the handle 3 is polygonal, which facilitates gripping and repositioning by hand; for example, a hexagonal shape may be used.

[0045] In an embodiment, the external ear canal shaver is an integral structure made of PEEK material, i.e., polyether ether ketone, a high-performance special engineering plastic, except for the blade 5. The external ear canal shaver made of PEEK material has good high-temperature resistance and good mechanical properties, and can be easily cleaned and high-temperature sterilized.

[0046] The external ear canal shaver provided by the utility model has simple structure, no or few precise components, can be directly cleaned and high-temperature sterilized, can effectively remove the external ear canal hair, meets the sterile requirement of operation, and is low in manufacturing cost and suitable for being used as disposable operation consumables.

[0047] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, according to the idea of the utility model, the specific implementation mode and application range will be changed by the general technical personnel in the field. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
