Medical tissue forceps and use method thereof

Abstract

The invention relates to medical tissue forceps and a use method thereof. The medical tissue forceps comprise an outer tube, a transmission piece, a sliding part and a guide rail part, wherein a far end of the outer tube is connected with a base, the joint between the outer tube and the base is provided with forceps head arms, openings can be formed between the forceps head arms and the base, anda near end of the outer tube is connected with a far end of the guide rail part; a far end of the transmission piece is connected with near ends of the forceps head arms, and a near end of the transmission piece penetrates through the outer tube and is connected with the sliding part; the sliding part can independently slide on the guide rail part, and the sizes of the openings of the forceps headarms relative to the base are controlled by sliding, so that the openings are opened and closed independently of each other; the guide rail part is provided with a guide rail locking part, the sliding part is provided with a sliding locking part, the sliding locking part and the guide rail locking part achieve separation and locking, thereby controlling the fixation and positioning of the forcepshead arms, and the states of the forceps head arms are not needed to maintain. The medical tissue forceps are easy to operate, can effectively reduce the difficulty of wound suture, and increases thesuccess rate of operation.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a surgical instrument for the digestive tract. Background technique [0002] In recent years, with the rapid development of endoscopic diagnosis and treatment, perforations in the digestive system such as the intestines and stomach can also be directly closed with the help of endoscopy, saving patients from surgical trauma. For the diagnosis and treatment of endoscopic perforation, hemostatic clips are commonly used to stop bleeding. However, due to the relatively small opening size of the existing hemostatic clips, it is difficult to achieve rapid hemostasis or clipping when used for large wounds or gastrointestinal perforation closure. In emergencies, it can only rely on laparotomy, with the help of surgeons to stop bleeding or suture the wound; laparotomy not only takes a long time to recover from large wounds, but also relatively high time and economic costs. [0003] At present, liga...

Problems solved by technology

For the diagnosis and treatment of endoscopic perforation, hemostatic clips are commonly used to stop bleeding. However, due to the relatively small opening size of the existing hemostatic clips, it is difficult to achieve rapid hemostasis or clipping when used for the closure of large wounds or digestive tract perforations. In emergency cases, we can only rely on laparotomy to stop bleeding or suture the wound with the help of surgeons; laparotomy not only takes a long time to recover from large wounds, but also has relatively high time and economic costs

[0003] Ligation devices currently on the market, such as purse loops, require multiple hemostatic clips to assist the ring to clamp the edge of the wound, thereby tightening the wound. When tightening the wound, the rate of hemostatic clips falling into the wound increases due to the large wound and many hemostatic clips. Big

This method not only wastes a certain amount of medical resources, but also increases the suffering and economic burden of patients.
