Description

Uterus traction device for hysterectomy under laparoscope

Technical Field

The utility model relates to an appliance for hysterectomy, in particular to a uterus traction device for hysterectomy under a laparoscope.

Background

Hysterectomy is a common gynecological operation and is the basic surgical mode for treating benign and malignant diseases of the uterus and even the attachments. According to QM typing, hysterectomies can be classified into simple hysterectomies (type A), sub-extensive hysterectomies (type B) and extensive hysterectomies (type C) due to the difference in scope of resection. Approaches include open hysterectomy, transvaginal vaginal hysterectomy, laparoscopic hysterectomy, and vulvally assisted laparoscopic hysterectomy. Among them, the hysterectomy under the laparoscope has been widely used in clinic because of its advantages of good operation visual field, easy mastering, less complication, less operation damage, fast postoperative recovery, etc.

In the hysterectomy under the laparoscope, in order to better expose tissues on two sides of the uterus and facilitate the operation, the uterus lifting operation is usually required, namely, a uterus lifting rod or a uterus lifting cup is put into the uterine cavity through the vagina, and the uterus lifting device is swung, so that the position of the uterus is changed, and the operation is easier. However, in recent years, the questions about uterine lifting, such as the damage of uterine cavity to endometrium, especially when carrying out cervical cancer operation, violate the tumor-free principle due to the stimulation and friction of uterine lifting operation to tumor lesion, and affects the operation prognosis. Therefore, in recent years, many operations, especially laparoscopic cervical cancer operations, have not been suggested. However, as the uterus is not lifted, when the ligament around the uterus is disconnected, the uterus tissue is not pulled and is difficult to move, and the operation visual field is exposed, the operation difficulty is obviously increased, and the number of operation complications is increased.

Detailed Description

The present invention will be described in detail with reference to fig. 1, 2 and 3, and the illustrative embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The utility model provides a hysterectomy uterus traction device under peritoneoscope, it is provided with actuating mechanism 2 and elasticity lasso 3 including the sleeve pipe 1 that can stretch into peritoneoscope puncture hole on this sleeve pipe, and this actuating mechanism drives elasticity lasso is followed sleeve pipe axial displacement removes and stretches out this sheathed tube elasticity lasso can overlap to establish and fix on the palace body of the free part of uterus. When the ligament beside the uterus is broken, the elastic lasso can be fixed on the free part of the uterus. The structure can be retracted into the sleeve at the initial stage of use, and is convenient to place into the abdominal cavity through a puncture hole of the laparoscope. The utility model discloses a sterile elastic lasso is convenient for accomodate on the one hand, and on the other hand avoids haring the uterus.

Specifically, the elastic noose is wound into a circle in a crossed manner, two ends of the elastic noose are arranged in the sleeve, and the elastic noose is driven to move by the driving mechanism. At the initial stage of use, the driving mechanism can drive the elastic noose to be accommodated in the sleeve; after the driving mechanism drives the ring part of the elastic lasso to extend out of the sleeve, the ring part of the elastic lasso can be sleeved and fixed on the uterus body of the free part of the uterus, so that the fixation of the uterus is realized. Preferably, one end of the elastic lasso is a free end, a buckle 4 is arranged in the middle of the free end, and the other end of the elastic lasso penetrates through the buckle to form a cross shape, so that the lasso is ensured not to be loosened.

Furthermore, the buckle 4 comprises a hollow frame 41 formed according to the cross section shape of the elastic lasso and a convex tooth 42 arranged on the inner wall of the hollow frame, the other end of the elastic lasso is correspondingly formed with a plurality of tooth grooves 43, and when the other end passes through the hollow frame, the convex tooth can be clamped into the corresponding tooth groove, so that the fixing space of the ring part can be adjusted according to the size of the uterus, and the elastic lasso is ensured to be fixed more stably. Specifically, the driving mechanism 2 includes a plunger 21 disposed in the casing and a hollow push-pull rod 22 driving the plunger to move axially along the casing, a push rod 23 is disposed in an inner cavity of the push-pull rod, the push rod penetrates through the plunger to push the hollow frame to move, and when the plunger presses the other end of the elastic lasso, the push rod pushes the hollow frame to move until a convex tooth of the hollow frame is clamped into a designated tooth socket. When the other end of the elastic lasso is compressed, the mandril pushes the hollow frame body to move, so that the fixing space of the ring part is reduced, and the uterus can be fixed. Meanwhile, the convex teeth and the tooth grooves are matched, so that looseness after fixation can be prevented. The cooperation of dogtooth and tooth's socket is similar to current binding band, and can fasten easily, can not become flexible easily.

Preferably, one side of the plunger is provided with a notch 24 which can accommodate the tail part of the free end of the elastic noose; the other side of the plunger is in a conical shape, and the conical plunger wall can press the other end of the elastic lasso, so that the fixing space of the elastic lasso ring part can be gradually reduced. At the initial stage of an operation, the elastic noose is completely accommodated in the sleeve, then the other end of the elastic noose can be tightly pressed on the inner wall of the sleeve through the plunger, and the elastic noose is driven to be gradually pushed out of the sleeve, at the moment, the fixing space of the elastic noose ring part is large enough, and the automatic end of the elastic noose passes through the notch, so that the movement of the elastic noose cannot be interfered; when the elastic lasso is pushed to the position right below the free uterus body of the uterus, the elastic lasso is driven to move upwards to enable the uterus to be positioned in the fixing space of the elastic lasso, then the ejector rod is moved to enable the hollow frame body to move, and the convex teeth can be clamped into the other tooth groove from the one tooth groove, so that the elastic lasso is fixed on the uterus; and then the plunger and the ejector rod are pulled back to loosen the other end of the elastic lasso, and then the pipe sleeve is withdrawn to expose the two ends of the elastic lasso, thereby realizing the fixation of the uterus.

The utility model discloses a afterbody at elasticity lasso both ends all is provided with through-hole 31, and two through-holes can be connected with the pull wire 5 that stretches into from left and right belly TROCAR hole respectively. After fixing uterus, the two ends of the elastic lasso are exposed, and the ends of the traction line can be provided with hooks which are directly hooked with the through holes at the two ends of the elastic lasso to realize traction. The utility model is connected with traction wires on the left and right sides of the fixed uterus part respectively, and is used for drawing the uterus body and moving the uterus body. Two traction wires are drawn out from TROCAR holes in the left lower abdomen and the right lower abdomen, and the length of the traction wires is controlled on an operating table to control the left and right swinging of the uterus, so that the uterus lifting is avoided.
