Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments, in particular to a medical planing handle. Background Art
[0002] During surgical procedures such as ENT, urology and gynecology, a planing knife is usually used to plan and remove the diseased tissue in the patient's body at a high speed, and the planing handle needs to provide it with driving force to complete the above functions. In order to remove the excised diseased tissue from the patient's body, a suction channel is generally provided in the planing handle. After the negative pressure aspirator is turned on, the suction channel forms a negative pressure, thereby expelling the excised diseased tissue from the patient's body. During use, the suction channel of the planing handle will enter the chopped tissue and flushing liquid of the human body. Since the handle is reusable, the planing handle needs to be cleaned and disinfected after the operation is completed.
[0003] In the prior art, the planing handle is usually formed by fine machining of an integrated shell, which requires the axis of the driving motor to be parallel to the center line of the planing tool to ensure stable output. Therefore, the processing of the parts is difficult and the manufacturing cost is high. At the same time, the planing handle is provided with a locking mechanism, a connection interface and a driving mechanism connected to the planing tool, and a suction channel is provided at the tail. Since the planing handle runs at a high speed and needs to be sterilized repeatedly, the internal locking mechanism and driving mechanism are not conducive to cleaning and maintenance, which increases the maintenance cost of the product.
[0004] In addition, the provision of the suction channel not only increases the difficulty of machining the parts of the handle, but also makes it inconvenient to clean the handle. What is worse, during the flushing process, flushing liquid enters the inside of the handle, affecting the normal operation of the motor and the drive mechanism. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] In the description of the present invention, it should be understood that terms such as "end", "upper", "lower", "side", "top", "bottom", "length", "inside", and "surface" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present invention.
[0033] In the prior art, the planing handle is mostly formed by fine machining of an integrated shell, which requires the axis of the driving motor to be parallel to the center line of the planing tool to ensure stable output. Therefore, the processing of parts is difficult and the manufacturing cost is high. At the same time, the planing handle is provided with a locking mechanism, a connection interface and a driving mechanism connected to the planing tool, and a suction channel is provided at the tail. Since the planing handle is operated at a high speed and needs to be sterilized repeatedly, the internal locking mechanism and driving mechanism are not conducive to cleaning and maintenance, which increases the maintenance cost of the product. In addition, the setting of the suction channel not only increases the difficulty of processing the parts of the handle, but also makes it inconvenient to clean the handle. What's more, during the flushing process, the flushing liquid enters the handle, affecting the normal operation of the motor and the driving mechanism. Based on this, this embodiment provides a medical planing handle, which adopts a hatch-type flip cover design to facilitate cleaning and maintenance; at the same time, the suction channel in the handle is cancelled to reduce manufacturing and maintenance costs.
[0034] See also Figure 1-Figure 2As shown, the medical shaver handle provided in this embodiment includes a main shell 1, a flip cover 2 and an upper cover 3. The flip cover 2 is flippably mounted on a first surface 101 at one end of the main shell 1, and forms a first installation cavity with the main shell 1. The upper cover 3 is fixedly mounted on a second surface 102 at the other end of the main shell 1, and forms a second installation cavity with the main shell 1. The second installation cavity is connected to the first installation cavity. The second installation cavity is a drive component installation cavity, which is mainly used to install a drive motor. The first installation cavity is a transmission component installation cavity. The flip cover 2 is designed to be flippable, which is convenient for opening the first installation cavity and thoroughly cleaning the interior thereof.
[0035] In a preferred embodiment of this embodiment, Figure 2 and Figure 4 As shown, the first surface 101 protrudes from the second surface 102 by a certain height, so that when the flip cover 2 is buckled on the first surface 101, one end of the flip cover 2 can be pressed on the surface of the upper cover 3 away from the main shell 1. And the surface of the upper cover 3 away from the main shell 1 is provided with a mounting groove 301 along the length direction for fixing the suction pipe. A through hole is provided between the end surface of the flip cover 2 away from the upper cover and the end surface of the main shell. When in use, the suction pipe is embedded in the mounting groove 301, and passes through the through hole of the end surface of the flip cover 2 and the main shell 1. Then, the flip cover 2 is snapped on to complete the fixing of the suction pipe. After use, the flip cover 2 is opened to remove the suction pipe for cleaning, which is convenient to use.
