Description

Technical Field

[0001] The utility model relates to the technical field of gynecological medical instruments, in particular to a laparoscopic hysterectomy device. Background Art

[0002] Hysterectomy is a common gynecological surgery, which can be divided into total hysterectomy, partial hysterectomy and extended hysterectomy. Hysterectomy can be performed through the abdomen or vagina, the former is called abdominal hysterectomy, and the latter is called vaginal hysterectomy. Laparoscopic hysterectomy avoids both the difficulties of vaginal surgery and the trauma of laparotomy, expanding the scope of minimally invasive surgery, and has obvious advantages. Laparoscopic hysterectomy refers to cutting off the ligaments, blood vessels, and vaginal walls around the uterus through a laparoscope, removing the uterus from the vagina, and then suturing the vaginal stump again under laparoscopy. When removing the uterus, an adapted laparoscopic hysterectomy device is required.

[0003] When using the currently common resection device for laparoscopic hysterectomy, if the patient's vaginal opening is narrow and the uterus is large, the removed uterus is difficult to pull out of the vagina, which can easily cause vaginal strain and cause great inconvenience to medical staff. For this reason, we propose a laparoscopic hysterectomy device. Utility Model Content

[0004] The main purpose of the utility model is to provide a laparoscopic hysterectomy device, which can assist in fixing the uterus during hysterectomy and improve the stability of resection. The resected uterus can be divided and removed, effectively avoiding adverse effects on the patient's vagina when the uterus is large in size and removed from the vagina. It is also convenient for medical staff to operate and use, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a laparoscopic hysterectomy device includes a uterine lifting cup 1 with open bottom and top, an extension ring 2 is integrally formed on the top of the uterine lifting cup 1, and a top ring 3 is fixed on the top of the extension ring 2, a resection component penetrating the extension ring 2 is installed between the inner periphery of the uterine lifting cup 1, an adjustment component is also installed on the inner periphery of the uterine lifting cup 1, and a rubber suction cup 19 for adsorbing and fixing the bottom of the uterus is screwed on the top of the adjustment component, and the outer periphery of the top ring 3 is structured with a plurality of notches.

[0025] The diameter of the rubber suction cup 19 is smaller than the inner diameter of the uterine lifting cup 1, the extension ring 2 and the top ring 3. The rubber suction cup 19 can be controlled by the adjustment component to achieve independent up and down movement, so that the rubber suction cup 19 can tightly adsorb the uterus, effectively preventing the uterus from shaking during hysterectomy and causing deviation in the resection position, thereby improving the stability during hysterectomy.

[0026] Specifically, Figure 1 and Figure 2As shown, the excision assembly includes a cross structure 6 fixed on the inner circumference of the uterine lifting cup 1, a first micro-electric adjustment rod 7 is installed and fixed at the center of the cross structure 6, an umbrella-shaped frame 8 is fixed to the top of the piston rod of the first micro-electric adjustment rod 7, a linkage ring 9 is fixed between the tops of the umbrella-shaped frame 8, a fitting rod 10 is fixed to the top of the linkage ring 9, the end of the fitting rod 10 is connected to a excision strip 11 passing through the extension ring 2, a uterine cutter 13 is inserted on the adjacent side of the excision strip 11, an auxiliary cutter mounting groove 12 is constructed on the outer side of the excision strip 11, an auxiliary cutter is installed in the auxiliary cutter mounting groove 12, and when the excision strip 11 is lifted, the uterine circumcision operation can be achieved by rotating the uterine lifting cup 1.

[0027] When the resection strip 11 is in a contracted state, its end is received in the notch. When the uterus is fixed by adsorption to the rubber suction cup 19, the first micro-electric adjustment rod 7 drives the resection strip 11 to move upward simultaneously through the umbrella-shaped frame 8, the linkage ring 9 and the fitting rod 10. The uterine cutting knife 13 on the inner side of the resection strip 11 can contact and fit with the outer side of the uterus, dividing the uterus into strips, so that the resected uterus can be subsequently placed into the inner side of the uterine lifting cup 1 and taken out together with the uterine lifting cup 1.

[0028] Specifically, a circular hole is configured on the rubber suction cup 19 , and a vacuum conduit 20 is sealedly connected to the inner circumference of the circular hole, and an end of the vacuum conduit 20 is connected to a vacuum machine 21 .

[0029] Under the action of the vacuum machine 21, the contact space between the rubber suction cup 19 and the uterus is conveniently evacuated to a vacuum state, thereby ensuring the adsorption effect of the rubber suction cup 19 and the uterus.

[0030] Specifically, the adjustment component includes a limit frame 14 symmetrically arranged and fixed on the inner circumference of the palace-raising cup 1, a cross bar 15 is fixed between the bottoms of the limit frame 14, a second micro-electric adjustment rod 16 is installed on the surface of the cross bar 15, and a threaded ring 17 is fixed on the top of the second micro-electric adjustment rod 16.

[0031] The rubber suction cup 19 can be independently controlled to move up and down, which is convenient for pre-adsorbing and fixing the uterus on the rubber suction cup 19. The cross-section of the limit frame 14 is an inverted L shape, and the gap between the limit frame 14 and the inner wall of the uterine lifting cup 1 allows the linkage ring 9 to move up and down.

[0032] Specifically, the threaded ring 17 is screwed and fixed to the threaded ring 18 , and the threaded ring 18 is integrally formed at the bottom of the rubber suction cup 19 .

[0033] The rubber suction cup 19 can be quickly screwed onto the top of the second micro-electric adjustment rod 16 through the threaded ring 17 and the threaded ring 18 .

[0034] Specifically, an annular groove is constructed on the inner circumference of the extension ring 2 , and a lighting strip 4 is nested and installed in the annular groove, and a miniature camera 5 is installed on the inner circumference of the top ring 3 .

[0035] With the help of the lighting strip 4 and the miniature camera 5, it is convenient to check the screen during the hysterectomy operation, thus avoiding large errors in the hysterectomy operation.

[0036] It should be noted that the utility model is a laparoscopic hysterectomy device. First, the patient is asked to lie on the operating table. After the patient's vagina is opened, the uterine lifting cup 1 is fixed to the end of a longer soft rod. The uterine lifting cup 1, the extension ring 2 and the top ring 3 are sent through the vagina to the cervix of the uterus through the soft rod. The rubber suction cup 19 is driven to move by the second micro-electric adjustment rod 16 so that the rubber suction cup 19 fits with the bottom of the uterus. The vacuum machine 21 extracts the air in the gap between the rubber suction cup 19 and the bottom of the uterus, so that the uterus and the rubber suction cup 19 are tightly connected. After adsorption, the second micro-electric adjustment rod 16 is retracted to a certain length, so that the bottom of the uterus fits with the surface of the top ring 3, and then the first micro-electric adjustment rod 7 is slowly extended. The first micro-electric adjustment rod 7 drives the resection strip 11 to move upward through the umbrella-shaped skeleton 8, the linkage ring 9 and the fitting rod 10, so that the uterine cutter 13 contacts the adsorbed and fixed uterus, and cuts the uterus to be removed into multiple strips, and then retracts the second micro-electric adjustment rod 16 again, pulls the removed uterus into the inside of the uterine lifting cup 1, and then takes it out together with the uterine lifting cup 1.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
