Description

A uterine lifter capable of automatically compressing the uterine cavity

technical field

The utility model belongs to the technical field of medical instruments, in particular to a uterine lifter capable of automatically compressing the uterine cavity.

Background technique

Total hysterectomy is a widely used surgical method in obstetrics and gynecology. It can be used to treat uterine fibroids, adenomyosis, uterine and ovarian tumors, etc. The traditional method is to cut the patient's abdominal cavity for total hysterectomy. Although this method can achieve hysterectomy, it has been gradually eliminated due to the disadvantages of large trauma area, long healing time, and expensive operation costs. It has been replaced by laparoscopic hysterectomy, which is currently widely used.

The biggest advantage of laparoscopic hysterectomy lies in the small trauma area, less interference to abdominal organs, less damage, quick recovery, and the ability to maintain a stable internal environment without obvious scars. However, there are also limitations such as small operating space. Therefore, in order to ensure the smooth operation process and reduce the risk of surgery, it is necessary to adjust the position of the uterus before hysterectomy, so that the uterus is in a position that is convenient for surgery, and it is also necessary to adjust the position of the adjusted uterus. Fixation is carried out to avoid risks such as uterine displacement during the operation.

At present, for the fixation of the position of the uterus, a uterine lifter is usually used, and its structure usually includes a rod-shaped or soft capsule-shaped compression part and a joystick connected to the compression part. During the operation, the compression part is inserted into the uterus from the patient's vagina. Inside, the surgeon or nurse operates the compression part through the joystick, so that the compression part squeezes the inside of the patient's uterus, and then adjusts and fixes the position of the uterus.

Although the above method can realize the adjustment of the position of the uterus, and can satisfy the fixation of the uterus to a certain extent, but in the actual operation, the inventor found that the current uterine lifter still has serious deficiencies, specifically as follows:

In the current uterine lifter, whether it is to adjust the position of the uterus or to fix the position of the uterus, it must make the compression part of the uterine lifter press the uterine wall, and the degree of compression determines whether the uterine lifter It can reliably fix the uterus and adjust the position of the uterus. Therefore, in the current use of the uterine lifter, it is necessary to use a large compressive force to ensure that the compressing part presses the uterine wall, thereby realizing the position adjustment and fixation of the uterus. In further in-depth research, the inventor found that such a large area of the uterus is squeezed vigorously, which will also cause serious problems, specifically: when the uterine wall is subjected to the above-mentioned squeezing force, the internal blood will be squeezed out of the uterus Into the tissues connected to the uterus, when there are malignant lesions in the uterus, such as malignant tumors, although the uterus is resected after the operation, other tissues are at great risk of infection and disease.

On the one hand, it may cause damage to the surrounding tissues; Risk of inflow into the abdominal cavity;

However, the uterine wall occlusal end A of this embodiment is used for occlusion, since the uterus can be fixed by occlusion, so it is not necessary to apply pushing pressure to ensure uterine fixation, which can greatly reduce or even It avoids the requirement of pushing the uterus, so it not only further reduces the extrusion of the uterine wall, but also reduces the requirements for the external operators or devices of the uterine lifter, and greatly reduces the working intensity of medical staff. It also reduces the cost of equipment; on the other hand, it also avoids the risk of the uterus moving forward due to the thrust at the moment when the uterus is cut off from the cervix, further reducing the risk of the uterus falling into the abdominal cavity or intrauterine tissue fluid flowing into the abdominal cavity, and greatly improving the operation efficiency. safety.

As a preferred embodiment, as shown in FIG. 6 , the uterine wall engaging end A is detachably connected to the grasping end. In the uterine lifter solution of the present application, the uterine wall occlusal end A is an easy-to-wear component, so the uterine wall occlusal end A and the grasping end are detachably connected, and the uterine wall occlusal end A can be easily replaced , to avoid the replacement of the entire uterine lifter, so that the use cost is further reduced, and the patient's medical expense burden is reduced.

As a preferred embodiment, further, as shown in FIG. 2 , the engaging portion 3 is a groove provided on the terminal body 1 . The occlusal part 3 is set as a groove, and when in use, a certain pressure is applied to the occlusal end A, so that part of the inner wall of the uterus is embedded in the groove, and the occlusion of the uterine wall is realized.

Further preferably, the groove is a V-shaped groove.

Further preferably, the terminal body 1 at the edge of the groove is sharp. A sharp angle is formed at this place, and the sharp angle can also penetrate into the uterine wall, thus further improving the stability and reliability of the occlusal tip engaging the uterine wall.

As another embodiment, as shown in FIG. 3 , the engaging portion 3 is an openable and closable engaging tooth provided on the terminal body 1 . In this manner, the opening and closing of the occlusal teeth can be conveniently controlled, thereby controlling the occlusion of the uterine wall or the release of the uterine wall.

As another embodiment, as shown in FIGS. 4 and 5 , the engaging portion 3 is several sharp protrusions arranged on the terminal body 1 . In this embodiment, by providing sharp protrusions, when the occlusal tip exerts pressure on the uterine wall, these sharp protrusions penetrate into the uterine wall, thereby achieving a reliable connection with the uterus.

Further preferably, the height of the sharp protrusion away from the tip body 1 is smaller than the thickness of the uterine wall.

Further preferably, the height of the sharp protrusion away from the tip body 1 is less than 2/3 of the thickness of the uterine wall. Through the above method, sharp protrusions are avoided from piercing the uterine wall and increasing the risk of surgery.

As a preferred embodiment, on the basis of the above solution, further, the terminal body 1 has an occlusal track, and when the terminal body 1 moves along the occlusal track, the terminal body 1 gradually presses the inner wall of the uterus, The sharp end of the sharp protrusion is bent away from the pressing direction of the terminal body 1 . In this embodiment, by setting the sharp protrusion in a curved shape, it is avoided that the sharp protrusion breaks away from the uterine wall when the tip moves in the opposite direction to the occlusal track, thus further improving the engagement between the occlusal part 3 and the uterine wall When it needs to be explained, the uterine lifter of this application is aimed at hysterectomy. Therefore, during the operation of the uterine lifter, even if there are actions such as occlusal or piercing of the uterine wall, it will not give any damage to the operation. result in adverse effects.

As a preferred embodiment, as shown in Figures 4 and 5, the end of the tip body 1 facing the inner wall of the uterus is an outwardly convex arc, and the sharp protrusions are distributed on the arc.

As another preferred embodiment, as shown in FIG. 5 , the end of the terminal body 1 facing the inner wall of the uterus extends along the direction of the bite track to form a strip, and the sharp protrusions are arranged on the strip. The side facing the uterine wall.
