Abstract

The utility model relates to a medical appliance, in particular to a celioscope traction splint for a laparoscopic surgery. The celioscope traction splint consists of a splint body (1), a traction line (2), and a long straight needle (3). A straight hole (12) is formed on the tail end of the splint holder of the splint body (1); and one end of the traction line (2) is tied to a hinged shaft which is arranged at the center of the splint body (2), while the other end is tied to the long straight needle (3). Because the splint body can be operated and controlled by inserting the head of a separating forceps into the straight hole of the splint holder, and the traction line and the long straight needle can be used for externally controlling and clamping a tissue to be pulled or held, the celioscope traction splint overcomes the disadvantages of a conventional line ligation or transfixion method, can change the holding position freely, and is convenient to operate. In the laparoscopic surgery, only two stomas for accommodating the celioscope and scalpels are opened on the abdominal part of a patient, so the celioscope traction splint relieves pain during the surgery reduces scars, improves surgery efficiency and success rate, and reduces surgery cost.
