Abstract

The invention relates to a multifunctional bionic pelvic operation retractor. The multifunctional bionic pelvic operation retractor is mainly composed of a pulling and bracing plate and a locating rod which are connected through a joint rotating shaft, wherein the pulling and bracing plate is of a curved surface structure, the middle of the curved surface is concaved inwards in the direction of the locating rod, the lower end of the pulling and bracing plate horizontally extends outwards, and the end of the pulling and bracing plate is provided with a membrane unfolding hook. According to the multifunctional bionic pelvic operation retractor, by means of the human arm imitation design and integration with an existing cold light source and wireless videoing technologies, a retractor device special for pelvic open operations is developed, multiple hard problems in pelvic operations can be solved simultaneously, an operative field is fully exposed, good lighting is achieved, and meanwhile smoke is sucked and removed, and the function of synchronous videoing is achieved. By means of the multifunctional bionic pelvic operation retractor, the difficulty of the pelvic operations can be reduced, the operating accuracy can be improved, and postoperative complications are reduced.

Example Embodiment

[0021] like figure 1 and figure 2 As shown in the figure, a multifunctional bionic pelvic surgery retractor is mainly composed of a brace plate 1 and a positioning rod 2. The brace plate 1 and the positioning rod 2 are connected by a joint shaft 3; The middle part is concave in the direction of the positioning rod, the lower end of the stretcher plate 1 is horizontally extended, and the end is provided with a downwardly extending film hook 4 .
[0022] The width of the brace plate 1 is 10-20 mm.
[0023] like image 3 As shown, the positioning rod 2 is provided with a retractable plastic threaded pipe 5, and the end of the plastic threaded pipe is provided with a miniature video camera, a lighting lamp or a suction tube device, a miniature video camera, a lighting lamp or a suction tube. The connecting wire of the device is connected to the external control device through the plastic threaded pipe 5 .
[0024] like Figure 4 As shown, a method of using a multifunctional bionic pelvic surgery retractor for pelvic surgery includes the following steps:
[0025] 1) Pre-positioning: set up a positioning frame on the side of the operating bed, connect the positioning rods 2 of at least 3 bionic pelvic surgical retractors to the positioning frame, and then adjust the position of the positioning rods 2 to ensure that several tensioning plates 1 form a pelvic circle. arc structure;
[0026] 2) Surgical retraction: After the patient's abdomen is incised, the opening is opened, and the bionic pelvic surgical retractor is put in, and the joint shaft 3 is adjusted by the adjusting rod or adjusting button to ensure that the curved concave surface of the brace plate 1 fits the inner wall of the pelvic cavity. Bladder, rectum and other organs, and at the same time, use the extension hook 4 to unfold Dun's fascia;
[0027] 3) Fine-tuning positioning: Position the positioning rod on the positioning frame, and fine-tune the distance to ensure that the abdominal cavity is fully exposed, and position the plastic threaded tube 5 with the corresponding function on the positioning rod, which is convenient for use during the operation.
[0028] The positioning frame is composed of a strut 11 and an arc-shaped positioning tube 12. The positioning block of the strut 11 is connected to the arc-shaped positioning tube 12, and the arc-shaped positioning tube 12 is connected to the multi-functional bionic pelvic surgery retractor through the positioning block.
