Description
Technical Field
The utility model relates to a medical appliance for laparoscopic surgery, in particular to a uterine manipulator with a memory function for laparoscopic cervical carcinoma surgery.
Background
The basic requirement of cancer operation is to avoid squeezing gently, so as to prevent and reduce hemorrhaging and lymphatic dissemination of cancer operation caused by human. Laparoscopic techniques are a trend of times of development, are representative of the application of new techniques in the medical field, and gain wide acceptance by doctors and patients. However, scholars at home and abroad have great disputes about the long-term curative effect of the laparoscopic early-stage cervical cancer surgery, and according to literature reports, the laparoscopic group has lower tumor-free survival rate and overall survival rate, higher recurrence rate and disease death rate than the laparotomy group for patients with early-stage cervical cancer. Mainly during the early cervical cancer operation of the laparoscope, the extrusion of the uterine lifting cup of the uterine lifter to a cancer focus and the abrasion to the vaginal wall cause bloody and lymph spread, and the complete or incomplete disconnection of the vagina under the laparoscope leads to the complete or partial exposure of the cancer focus and the shedding and spreading of cancer cells. In order to solve the problems of the uterine lifting cup in the early cervical cancer operation of the laparoscope, a simple uterine lifting device is adopted to replace a cup type uterine lifting device, but the uterine lifting effect is not satisfactory enough, cervical tissues are clamped during use, the cancer focus is still extruded, and the bloodiness and lymphatic spread caused by the extrusion of the cancer focus cannot be effectively solved by the conventional uterine lifting device.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a uterus lifter for laparoscope cervical carcinoma operation, which has simple operation, convenient use and satisfactory uterus lifting, and can avoid the extrusion of a cancer focus in the operation process and has the memory function.
In order to achieve the above object, the present invention comprises: the uterine manipulator comprises a uterine lifting rod, a fixing screw, an operating handle, an outer sleeve and an inner sleeve, wherein the uterine lifting rod is arranged in the inner sleeve, the fixing screw is arranged on one side of the lower end of the inner sleeve, the inner sleeve is arranged in the outer sleeve, the operating handle is symmetrically arranged at the lower end of the outer sleeve, the fixing screw is arranged below the operating handle, the uterine lifting rod is composed of a memory alloy, a rod body and an injection interface, the upper end of the rod body is connected with the memory alloy, the lower end of the rod body is connected with the injection interface, and a liquid channel is arranged between the rod.
The top end of the memory alloy of the womb lifting rod is provided with a conical small bulge.
Thus, in the early cervical cancer resection operation of the laparoscope, firstly, the close section of the uterine tube narrow part is electrocoagulated to block and close the tube cavity under the laparoscope, then the memory alloy end of the uterine lifting rod is put into the sterilization liquid with the temperature of 0-5 ℃ to change the memory alloy into a cylindrical state, and the memory alloy end of the uterine lifting rod can be conveniently inserted into the uterine cavity through the vagina by installing the inner sleeve and the outer sleeve. Injecting 45-50 ℃ sterile water for injection into the memory alloy end by using the injection port, opening the memory alloy end due to the action of water temperature and body temperature, continuously maintaining the memory state similar to the uterine cavity, filling the uterine cavity, and adjusting and fixing the positions of the inner sleeve and the outer sleeve so as not to contact with cervical lesion tissues. According to the needs in the operation, the operation handle is used for operation, the position of the womb is adjusted and swung, and a satisfactory womb lifting effect is obtained. After the cervical cancer is resected, the uterus is pulled out together through the vagina, so that the bloody and lymph spreading caused by the extrusion of the celioscope cervical cancer operation on the cancer tissue is avoided, and the probability of the abdominopelvic cavity planting transfer caused by the fallen cancer cells is reduced. The utility model discloses the uterus rod of lifting that the uterus rod replaced cup type uterus lifting device with memory function is used for benign pathological change hysterectomy, can obtain more satisfied uterus effect of lifting, and is more convenient when pulling out the uterus through the vagina, and the clamp of being convenient for prevents to return and contracts, reduces the operation degree of difficulty. The small conical bulge at the top end of the uterine lifting rod memory alloy plays a role in fixing the uterine lifting rod and can also avoid serious complications of pelvic organ and blood vessel injury caused by the fact that the uterine lifting rod penetrates through the uterus.

Detailed Description
As can be seen from fig. 1 and 2, the present invention includes: a uterine manipulator, a fixing screw 2, an operating handle 3, an outer sleeve 4 and an inner sleeve 6. The uterine lifting rod is arranged in the inner sleeve, the uterine lifting rod can move up and down in the inner sleeve 6 in an operation, and a fixing screw 2 is arranged on one side of the lower end of the inner sleeve and used for fixing the upper position and the lower position of the internal uterine lifting rod. The inner sleeve 6 is arranged in the outer sleeve 4, the inner sleeve can move up and down in the outer sleeve in the operation, the symmetrical operating handles 3 are arranged at the lower end of the outer sleeve, and the lower sides of the operating handles are provided with fixing screws for fixing the upper position and the lower position of the inner sleeve inside the operating handles. The uterus lifting rod is composed of a memory alloy 7, a rod body 5 and an injection interface 1, the upper end of the rod body is connected with the memory alloy, the lower end of the rod body is connected with the injection interface, a liquid channel 8 is arranged inside the rod body and the memory alloy, and the sterilized normal saline liquid can be injected into the interior of the rod body and the memory alloy through the injection interface. The memory alloy is nickel-titanium memory alloy, becomes a cylindrical state at 5-10 ℃, is in an open state when the temperature rises to 30-35 ℃, can be restored to a memory state similar to the shape of the uterine cavity when being opened, fills the uterine cavity, and has a conical small bulge 9 at the top end to play a role in fixing the uterine lifting rod. The uterine manipulator, the fixing screw, the operating handle, the outer sleeve and the inner sleeve are made of sanitary materials, and the requirements of operation standards are met. The memory alloy part of the uterus lifting rod can be made into different series according to the size of the uterine cavity of a patient.
