Description

Uterus lifting device Technical Field The invention belongs to the technical field of medical appliances, and particularly relates to a uterus lifting device. Background Uterine lifting instruments are one of the recently emerging laparoscopic instruments and are mainly used for fixing and lifting uterus in a full-or sub-full-incision operation. According to different designs, the uterine manipulator is divided into three main types, namely a multi-head uterine manipulator, a head-blocking uterine manipulator and a cup-type uterine manipulator, wherein the cup-type uterine manipulator is a common uterine manipulator. In addition, the fixing mechanism of the cup type uterine manipulator cannot meet the force of pulling outwards, the operation effect on huge uterus is poor, the rod core is completely inserted into the uterine cavity, and the rod core is quite suitable for excision of small uterus, but is quite suitable for excision of large uterus, especially large uterus, but the operation space is limited, and the operation exposure is seriously affected. Disclosure of Invention Accordingly, the present invention is directed to a uterine lifting device, which overcomes the above-mentioned drawbacks, and can well fix a cervical canal, reduce the operation difficulty, and is practical and practical. In order to achieve the above purpose, the technical scheme of the invention is realized as follows: When the uterus lifting device is used, the uterus lifting mechanism is arranged at a cervical canal of a patient, and the clamping mechanism is driven by the telescoping mechanism to fix the cervical canal. In the above scheme, the clamping mechanism comprises a probe assembly and a tooth piece, wherein the probe assembly is inserted into the uterus lifting mechanism, and the tooth piece is arranged in the probe assembly and extends out of the probe assembly. In the above scheme, the probe assembly comprises a needle head and a needle body, a containing cavity for containing the dental film is formed between the needle head and the needle body, one end of the dental film is arranged in the containing cavity, and the other end extends out of the containing cavity and is connected with the telescopic mechanism. In the above scheme, the needle head, the needle body and the accommodating cavity are integrally formed. In the above scheme, the accommodating cavity is provided with a cover body, and the cover body is connected with the accommodating cavity in a matched manner. According to the technical scheme, the telescopic mechanism comprises a telescopic rod, a rotating nut and a transmission rod, wherein the telescopic rod is inserted into the needle body and the accommodating cavity, the rotating nut is arranged on one end, far away from the accommodating cavity, of the telescopic rod, one end of the transmission rod is connected with the telescopic rod, the other end of the transmission rod is connected with the dental film in a matched mode, and when the telescopic mechanism is used, the rotating nut drives the telescopic rod to stretch and retract, so that the dental film clamps cervical tubes under the action of the transmission rod. In the above scheme, the telescopic rod is provided with a clamping groove for accommodating the transmission rod. In the above scheme, the uterus lifting mechanism comprises a cup body, a cup handle and a limiting piece, wherein the cup body is sleeved on the accommodating cavity, the cup handle is sleeved on the needle body, and the cup body is connected with the cup handle through the limiting piece. In the scheme, the cup body and the cup handle are provided with threads matched with the limiting piece. In the scheme, the cup handle is provided with the handle. In the above scheme, the uterus lifting device further comprises a fixing nut for fixing the needle body, and the fixing nut is connected with the needle body in a matched mode through the cup handle. Compared with the prior art, the cervical canal clamping device has the advantages that the clamping mechanism is arranged in the uterine lifting mechanism, and the telescopic mechanism is connected with the clamping mechanism in a matched manner, so that the telescopic mechanism can drive the clamping mechanism to clamp the cervical canal, cervical canal with different diameters can be matched, the cervical canal fixing device can be fixed in an operation and is not easy to slip off, the force for pulling the uterus outwards can be met, the requirement of exposing operation is met, the structure is simple, the practicability is high, and the experience of an operator is good.
