Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly or indirectly connected to the other element, and the "connection" does not limit the fixed connection or the movable connection, and the specific connection mode should be determined according to the specific technical problem to be solved.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings that is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the utility model.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Example (b):

the utility model provides an orthopedics stripper, contains handle of a knife (2) and tool bit (1), characterized by: still contain hose (3), hose (3) run through tool bit (1) and handle of a knife (2), and hose (3) and negative pressure device intercommunication. The liquid suction switch is arranged on the knife handle (2); the liquid suction switch comprises an extrusion wheel (31) and an extrusion bin (33); a guide rail (34) is arranged on the cutter handle (2), the extrusion wheel (31) is arranged in the guide rail (34) through a bearing (32), and the bottom surface of the extrusion bin (33) is inclined to the guide rail (34); the hose (3) penetrates through the extrusion bin (33).

As the bottom surface of the extrusion bin (33) is inclined with the guide rail (34), the extrusion wheel (31) moves on the guide rail (34) and changes the position relative to the bottom surface of the extrusion bin (33) in the process of pushing the extrusion wheel (31). When the extrusion wheel (31) is close to the bottom surface of the extrusion bin (33), the hose (3) is extruded, the hose (3) is in a closed state, no negative pressure exists at the position of the cutter head (1), and the cutter head (1) can be prevented from being adsorbed on tissues in the operation process and being torn when moving. When the ground of the bin (33) is extruded by the principle of the extrusion wheel (31), the hose (3) is not extruded and is in a passage state, and the cutter head (1) has negative pressure, so that blood can be normally absorbed.

The embodiment further comprises a pipeline (4), the pipeline (4) penetrates through the cutter handle (2) and the cutter head (1) and is communicated with the extrusion bin (33), and the hose is arranged in the pipeline. The inlet of the pipeline (3) is positioned at the cutter head, and the inlet (5) is trumpet-shaped. The inlet of the hose (3) is arranged at the inlet (5) of the pipeline and is trumpet-shaped. The hose inlet (5) is matched with the trumpet shape of the pipeline inlet (5).

When the operation is completed, the tissue fluid is in the hose (3), and if the hose (3) needs to be thoroughly cleaned, the hose (3) needs to be detached. After the pipeline (4) is arranged, the hose (3) can pass through the stripper through the pipeline (4), so that the hose (3) can be replaced conveniently. The opening of the pipeline (4) at the cutter head (1) is matched with the opening of the hose (3) to ensure that the hose (3) is installed in place.

The embodiment also comprises a filter screen (6), wherein the filter screen (6) is arranged at the cutter head hose inlet (5).

The main function of the filter screen is to prevent large tissue from entering the hose (3) and causing blockage of the hose (3).

The negative pressure device of the present embodiment is a vacuum pump. The cutter head (1) is also provided with a blade (7).

The working principle is as follows: after a doctor peels off periosteum through the blade, the doctor finds exuded blood, pushes the extrusion wheel, aligns the opening of the soft tube of the cutter head with the blood, and absorbs the blood. After that, the squeezing wheel is restored and the hose is closed. After the operation is finished, the hose and the negative pressure device are firstly detached, the extrusion wheel is pushed to the opening side, the hose is drawn out from the cutter head, and after the hose is cleaned, the hose is thrown out and inserted into the stripper.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
