Description

Technical Field

[0001] The utility model relates to the technical field of medical endoscope equipment, in particular to a double-groove slide rail sealing structure. Background Art

[0002] The rigid endoscope is mainly composed of an optical imaging system and a lighting system: the optical part looks like a long and thin metal tube, and inside it is a complete optical system composed of many lenses. The optical imaging system consists of three major systems: the objective system, the image transfer system, and the eyepiece system. The inverted image of the object under observation formed by the objective lens is converted into a positive image through the image transfer system and transmitted to the eyepiece, which is then magnified by the eyepiece and observed by the human eye. It is mainly used for the diagnosis and (or) treatment of lesions in the superficial and shallow natural cavities of the human body and through puncture of the oral cavity, such as cystoscopes and hysteroscopes, and cannot be bent during operation.

[0003] However, the replaceable tube installed in the rigid endoscope used in minimally invasive surgery is replaced when a larger instrument channel needs to be replaced. Currently, this replaceable tube is directly plugged into the end of the endoscope and installed. There is no guide structure to guide the replaceable tube, which causes tilting or deviation, affecting the use of the equipment. Utility Model Content

[0004] According to the above existing technical problems, the utility model provides a double-groove slide rail sealing structure, which is characterized by comprising an end head, a detachable tube, a fixed tube, a crescent tube, a guide slide rail, and a connecting block. One end of the detachable tube is inserted into the end head, and a plurality of fixed tubes are arranged at a position below the detachable tube in the end head, and the plurality of fixed tubes are sleeved and connected in the crescent tube. Guide slide rails are installed on both sides of the crescent tube, and both sides of the lower part of the detachable tube are respectively connected to the connecting block, and the connecting block is slidably connected to the T-shaped slide groove arranged in the guide slide rail.

[0005] The connecting block is arranged in a T-shaped structure.

[0006] Beneficial effects of the utility model:

[0007] The utility model provides guide rails with T-shaped slide grooves on both sides of the crescent tube. When the detachable tube is plugged in and installed, the connecting blocks on both sides of the detachable tube move in the guide rails, which guides the detachable tube when it is plugged into the end head, thereby preventing the detachable tube from tilting or deflecting during installation.

[0008] The double-groove slide rail sealing structure designed in the utility model can reduce the deviation of the detachable tube when the endoscope enters the established surgical channel, so as to keep it stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0013] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] Example 1

[0016] As shown in the figure, one end of the detachable tube 1 is inserted into the end head 2, and a plurality of fixed tubes 3 are arranged at a position below the detachable tube 1 in the end head 2. The fixed tubes 3 extend into the end head 2, and the plurality of fixed tubes 3 are sleeved and connected in the crescent tube 4. Guide rails 5 are installed on both sides of the crescent tube 4. The connecting blocks 6 respectively arranged on both sides of the lower part of the detachable tube are slidably connected in the T-shaped grooves arranged in the guide rails 5, and the connecting blocks 6 are arranged into a T-shaped structure.

[0017] The utility model arranges guide rails 5 with T-shaped slide grooves on both sides of the crescent tube 4. When the detachable tube 2 is plugged in and installed, the connecting blocks 6 on both sides of the detachable tube 2 move in the guide rails 5, which guide the detachable tube 2 when it is plugged into the end head 1, and prevents the detachable tube 2 from tilting or shifting during installation. The double-groove slide rail sealing structure designed by the utility model reduces the shifting of the detachable tube 2 during operation when the endoscope enters the established surgical channel, so that the detachable tube 2 remains stable.

[0018] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field.
