Description

Technical Field

[0001] The utility model relates to the field of otology, in particular to a special stripper for otology. Background Art

[0002] An ear stripper is usually a special tool used in ear surgery. It has a fine design and is used for ear surgery. It is mainly used for ear stripping surgery to help doctors separate the skin and soft tissue of the ear for further treatment. An ear stripper is usually composed of a blade and a handle. When using an ear stripper, it needs to be performed by professional medical personnel in an appropriate medical environment and follow relevant medical operating specifications and safety standards. At the same time, the knife needs to be strictly disinfected and cleaned before and after use to prevent cross infection.

[0003] The Chinese patent with patent number CN201821857697.4 discloses "A suction stripping knife capable of multi-directional stripping". The suction stripping knife is provided with a P-shaped stripping knife, so that the stripping knife can be moved forward and backward along the ear canal for stripping, which makes up for the defect that the existing stripper can only strip forward and backward alone, realizes multi-directional stripping, avoids accidents caused by frequent rotation and changing direction, and contacts the stripping part with the arc-shaped edge, so that the blade and the contact part are evenly stressed, thereby improving the success rate of the operation;

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] During use, the tool of this structure has the ability of adsorption on only one side. Therefore, when the blade moves forward and backward for peeling, and peels downward on the ear canal on the side of the adsorption port, the soft tissue is peeled off from the other end of the blade. The adsorption port cannot directly adsorb the fallen soft tissue through the blade body, causing the soft tissue to fall into the ear canal. The fallen soft tissue cannot be adsorbed in time, which increases the inconvenience in subsequent operations. After the blade body is damaged after long-term use, the blade can only be replaced as a whole, which is a waste of resources. At the same time, the hollow peeling rod is at risk of deformation due to external collision pressure, which affects its use and is not conducive to the safe placement of the peeling rod. Utility Model Content

[0006] Therefore, it is necessary to provide an ear-specific stripper to solve the problems that the existing strippers cannot absorb soft tissue in time, have a low reuse rate, and are easily deformed under the action of external forces.

[0007] To achieve the above-mentioned purpose, the utility model provides a special stripper for ear department, including a stripping rod, a protective sleeve, an adsorption channel, an adsorption member, a stripping knife, a shaping rod, and a rubber connecting sleeve;

[0008] The outer side of the stripping rod is covered with a protective sleeve, and the inner side of the stripping rod is provided with an adsorption channel;

[0009] The bottom end of the adsorption member is threadedly connected to the stripping rod, and a stripping knife is welded at the middle of the top end of the adsorption member;

[0010] The outer side of the shaping rod is provided with a rubber connecting sleeve, and the shaping rod is embedded upward into the inner side of the stripping rod.

[0011] Preferably, the adsorption component includes a base, a welding separation area, a collecting channel, and a fulcrum adsorption port. The bottom end of the base is threadedly connected to the stripping rod, and a welding separation area is provided at the top. A stripping knife is welded inside the welding separation area. The upper and lower ends of the base are respectively provided with a fulcrum adsorption port and a collecting channel, and the collecting channel is connected to the adsorption channel.

[0012] Further preferably, the cross-section of the fulcrum adsorption port is inclined, so as to increase the adsorption area of ​​the fulcrum adsorption port, thereby facilitating the adsorption of larger pieces of soft tissue, providing a larger channel for the adsorption of soft tissue, accelerating the speed of successful adsorption, and thereby shortening the time of ear canal surgery.

[0013] Further preferably, there are two groups of fulcrum adsorption ports, which are distributed at the left and right ends of the welding separation area, and further distributed at the two ends of the stripping knife, so that when the stripping knife strips both sides of the ear canal, the stripped soft tissue can be adsorbed in time, effectively preventing the stripped soft tissue from falling into the ear canal.

[0014] Further preferably, the welding separation area is arranged in the middle of the top of the substrate, dividing the top of the substrate into two groups, forming two groups of fulcrum adsorption ports of equal size, so as to facilitate timely adsorption of the soft tissues stripped at the left and right ends of the stripping knife.

[0015] Further preferably, the top of the rubber connecting sleeve is provided with a chamfer to facilitate the embedding of the rubber connecting sleeve and the shaping rod into the interior of the stripping rod to achieve rapid embedding. Through the embedding of the shaping rod, the interior of the stripping rod is saturated and supported, thereby reducing the impact of external force extrusion, and greatly avoiding the stripping rod from being deformed by pressure, causing the adsorption channel to deform and the cross-section to shrink, affecting the speed at which the soft tissue passes through the adsorption channel, and further affecting the overall adsorption speed of the soft tissue.

[0016] Further preferably, the cross-section of the shaping rod is "T"-shaped, and the diameter of its upper end is similar to the diameter of the adsorption channel, so that the shaping rod can be easily embedded in the adsorption channel, and the tightness of the connection between the shaping rod and the stripping rod can be strengthened with the help of a rubber connecting sleeve, so that the shaping rod can be stably embedded in the interior of the stripping rod to achieve protection.

[0017] Further preferably, the cross-section of the peeling rod is in the shape of a "cross", and a protective cover is provided on the lateral protrusion thereof. The setting of the protrusion is convenient for the operator to grasp, and the protective cover increases the friction, strengthening the connection between the operator's hand and the peeling rod, avoiding the slipping of the gloves on the peeling rod during use, causing the peeling rod to shake and causing damage to the ear canal, thereby improving the safety and stability of operations in the ear canal.

[0018] Further preferably, the stripping knife is made of pure titanium, which has good biocompatibility, low toxicity, and is non-allergenic and has no side effects on the human body. Pure titanium material is extremely friendly to human tissue and almost never causes allergic reactions, and is usually used in the preparation of surgical knives.

[0019] Different from the prior art, the above technical solution provides two groups of left and right fulcrum adsorption ports with the stripping knife as the center by setting an adsorption part, so that the stripping knife can timely adsorb the peeled soft tissue when stripping the soft tissue, and prevent the soft tissue from falling into the ear canal. In addition, through the detachable stripping rod and adsorption part, one group of damaged parts can be replaced, thereby improving the recycling rate of parts. In addition, through the embedding of the shaping rod, the adsorption channel of the stripping rod is filled, which greatly reduces the possibility of deformation and damage of the stripping rod due to external pressure, thereby improving the safety of the stripper when placed.

[0046] See also Figure 1-5The utility model provides a special stripper for ear department, comprising a stripping rod 1, a protective sleeve 2, an adsorption channel 3, an adsorption member 4, a stripping knife 5, a shaping rod 6, and a rubber connecting sleeve 7; the outer side of the stripping rod 1 is sleeved with the protective sleeve 2, and the interior of the stripping rod 1 is provided with the adsorption channel 3; the bottom end of the adsorption member 4 is threadedly connected with the stripping rod 1, and the stripping knife 5 is welded at the middle part of the top end of the adsorption member 4; the outer side of the shaping rod 6 is provided with the rubber connecting sleeve 7, and the shaping rod 6 is upwardly embedded in the interior of the stripping rod 1.

[0047] Among them, the adsorption component 4 includes a base 41, a welding separation area 42, a collecting channel 43, and a fulcrum adsorption port 44. The bottom end of the base 41 is threadedly connected to the stripping rod 1, and a welding separation area 42 is provided at the top thereof. A stripping knife 5 is welded inside the welding separation area 42. The upper and lower ends of the base 41 are respectively provided with a fulcrum adsorption port 44 and a collecting channel 43, and the collecting channel 43 is connected to the adsorption channel 3.

[0048] In this embodiment, the cross-section of the fulcrum adsorption port 44 is inclined, which is convenient for increasing the adsorption area of ​​the fulcrum adsorption port 44, thereby facilitating the adsorption of larger pieces of soft tissue in the ear canal, providing a larger channel for the adsorption of soft tissue, and accelerating the speed of successful adsorption, thereby shortening the time of ear canal surgery and improving surgical efficiency.

[0049] In this embodiment, two groups of fulcrum adsorption ports 44 are provided, which are distributed at the left and right ends of the welding separation area 42, and further distributed at the two ends of the stripping knife 5. This makes it convenient for the stripping knife 5 to strip the front and back sides or the left and right sides of the ear canal. The stripped soft tissue can be adsorbed in time, effectively preventing the stripped soft tissue from falling into the ear canal and affecting subsequent operations.

[0050] In this embodiment, the top of the rubber connecting sleeve 7 is provided with a chamfer, which facilitates the embedding of the rubber connecting sleeve 7 and the shaping rod 6 into the interior of the stripping rod 1 to achieve rapid embedding. Through the embedding of the shaping rod 6, the interior of the stripping rod 1 is saturated and supported, thereby reducing the impact of external force squeezing, and greatly avoiding the stripping rod 1 from deforming under pressure, causing the adsorption channel 3 to deform and the cross-section to shrink, affecting the speed at which the soft tissue passes through the adsorption channel 3, and further affecting the overall adsorption speed of the soft tissue.

[0051] In this embodiment, the welding separation area 42 is arranged in the middle of the top of the base 41, dividing the top of the base 41 into two, forming two groups of fulcrum adsorption ports 44 of equal size, which is convenient for timely adsorption of the soft tissue peeled off at the left and right ends of the peeling knife 5, and avoiding the soft tissue from falling into the ear canal after it detaches from the inner wall of the ear canal.

[0052] In this embodiment, the cross-section of the shaping rod 6 is "T"-shaped, and the diameter of its upper end is similar to the diameter of the adsorption channel 3, which is convenient for embedding the shaping rod 6 into the adsorption channel 3, and the rubber connecting sleeve 7 is used to strengthen the tightness of the connection between the shaping rod 6 and the stripping rod 1, so that the shaping rod 6 is stably embedded in the interior of the stripping rod 1, and the interior of the stripping rod 1 is propped up to avoid deformation of the stripping rod 1, thereby achieving the purpose of protecting the stripping rod 1.

[0053] In this embodiment, the cross-section of the peeling rod 1 is in the shape of a "cross", and a protective cover 2 is provided on its lateral protrusion. The setting of the protrusion is convenient for the operator to grasp, and the protective cover 2 increases the friction, strengthens the connection between the operator's hand and the peeling rod 1, and avoids the slipping of the gloves on the peeling rod during use, causing the peeling rod to shake and cause damage to the ear canal, thereby improving the safety and stability of operations in the ear canal. The protective cover 2 is made of rubber, and through the inherent anti-slip properties of rubber and the anti-slip texture set on the outside of the protective cover 2, it plays a dual anti-slip role, strengthens the tightness of the connection between the hand and the protective cover 2, and thereby improves the stability and safety during operation.

[0054] In addition, the bottom end of the stripping rod 1 is connected to a special negative pressure suction machine for ear department, and the negative pressure suction machine is used as the main driving source to provide adsorption force for the stripping rod 1, thereby generating suction force through the negative pressure suction machine, and adsorbing the soft tissue stripped in the ear canal through the adsorption channel 3. The soft tissue adsorbed into the negative pressure suction machine will enter into a bottle-shaped collection container specially provided inside the negative pressure suction machine, thereby facilitating the unified collection and processing of the soft tissue in the collection container, thereby improving the convenience of soft tissue processing.

[0055] In addition, before using the stripper, the integrity and sharpness of the tool need to be checked to ensure that the tool is not damaged or missing, so as not to affect the operation effect and safety. After checking the integrity of the tool, the tool still needs to be thoroughly disinfected to prevent bacterial and fungal infection. After the stripping knife is used, the surgical knife needs to be thoroughly cleaned and disinfected again to prevent cross infection. After thorough cleaning and disinfection, it should be placed in a drying device for drying and then properly stored.

[0056] See also Figure 1-5 Before use, remove the shaping rod 6 embedded in the stripping rod 1, and check the integrity and sharpness of the stripper and other knives to ensure the integrity of the knives, and disinfect and sterilize the stripper and other knives again to prevent infection before use;

[0057] When in use, the stripping knife 5 is used to strip the soft tissue of the inner wall of the ear canal, and during the stripping process, it is necessary to flexibly control the use of the negative pressure aspirator to generate a suitable negative pressure inside the stripper, drive the fulcrum adsorption port 44 to timely adsorb the fallen soft tissue, and collect and transmit the soft tissue through the fulcrum adsorption port 44 to the collection channel 43 and the adsorption channel 3, and enter the collection container of the negative pressure aspirator;

[0058] After using the stripper, the residual blood, soft tissue debris, etc. inside need to be cleaned in time, and the knives used in the operation should be deeply immersed and disinfected, and then placed in a drying device for drying after deep disinfection, and finally the shaping rod 6 should be embedded in the adsorption channel 3 for proper storage.

[0059] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
