However, there are disadvantages in this operation: 1. The abdominal wall still needs to be perforated, which has certain trauma and affects the appearance; 2. The operation requires C0 2 Equally inflated abdomen leads to disturbance of acid-base and electrolyte balance in the patient's circulatory system; 3. Pneumoperitoneum presses close to the diaphragm, resulting in obstruction of cardiopulmonary circulation and increasing surgical risk
Transvaginal surgery refers to surgery through the female natural orifice, that is, the vagina. Although the surgical approach is less traumatic, it is still subject to many restrictions; 1. The surgical field of view is small, which greatly restricts the scope of surgery through this approach; 2. The vagina is relatively deep , it is difficult for the operator to operate, and it also seriously restricts the scope of surgery through this approach

[0005] control figure 1 , figure 2 , Figure 2A , Figure 2B , Figure 2C , Figure 2D , Figure 2E , Figure 2F , image 3 , Figure 3A , Figure 3B As can be seen, the present invention is made up of dilator, blood vessel forceps, surgical scissors. The expander includes a scissors body 1, and a shrapnel 2 is respectively provided on one side of the two cutting heads of the scissors body 1, and one end of the shrapnel 2 is fixedly connected with the cutting head, and the other end is provided with a toothed slot 3, and the snap The groove is used in conjunction with the protrusion 4 on the shearing head. By adjusting the matching position of the locking groove and the protrusion, the shrapnel can bounce up in an arc shape, which can expand the abdominal cavity forward and open the organs in the abdominal cavity. At the same time, when the shearing head is opened, it can The abdominal cavity is expanded left and right, and the organs in the abdominal cavity are pro...

The invention provides a transvaginal endoscope operative instrument which comprises an expander, a pair of vascular forceps and a pair of operating scissors. The expander comprises a scissor body. Two elastic sheets are respectively arranged on one faces of two scissor heads of the scissor body. One end of each elastic sheet is fixedly connected with one scissor head. The other end of each elastic sheet is provided with a serrated clamp groove which is matched with a clamp protrusion arranged on the scissor head to use. The vascular forceps are a pair of straight-grip type vascular forceps which are formed by straight-grip handles, an operation rod and vascular forcep heads through combination. The operation rod and the vascular forcep heads are combined into a whole and connected with the straight-grip handles in an inserting mode. The head of the operation rod is in an arc shape. The operating scissors are a pair of straight-grip operating scissors which are formed by straight-grip handles, an operation rod and scissor heads through combination. The head of the operation rod is in an arc shape. The transvaginal endoscope operative instrument enlarges an operational visual field, extends an operational range of fingers of an operator, is really noninvasive, and simultaneously avoids various disadvantages due to the fact that a laparoscope is used for aerating the abdomen.
Description
technical field [0001] The invention relates to a medical device, in particular to a surgical device in the fields of minimally invasive medicine such as obstetrics and gynecology, surgery and diagnostics. Background technique [0002] Currently, there are three types of intra-abdominal surgery for women: laparotomy, transabdominal laparoscopic surgery, and transvaginal surgery. Among them, laparotomy is a traditional surgical approach. With the progress of society and economic development, many disadvantages have emerged: 1. Trauma caused by laparotomy; 2. Significant postoperative pain; 3. Slow recovery of intestinal tract and various life weights after surgery ; 4. Long hospital stay; 5. Obvious postoperative scars affect the appearance and bring great pain to patients, especially for women. Therefore, laparotomy can no longer meet the requirements of modern patients, it is necessary to find other minimally invasive or non-invasive surgery. Perforating laparoscopic surg...
