Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 7, the laparoscopic lower uterus positioning traction device of the present invention includes a central guide rod 100, a first sliding rod 203, a second sliding rod 204, a first adjusting mechanism and a second adjusting mechanism.
The central guide rod 100 comprises a first rod body 101, a second rod body 102 and a flexible hose 103 connected between the first rod body 101 and the second rod body 102, wherein the first rod body 101, the second rod body 102 and the flexible hose 103 are hollow and communicated, a grip 1011 is arranged at one end of the first rod body 101 away from the flexible hose 103, which is convenient for an operator to hold in operation, a womb rod 106 is coaxially arranged at one end of the second rod body 102 away from the flexible hose 103, the diameter of the womb rod 106 is smaller than that of the second rod body 102, a womb lifting cup 105 is sleeved on the peripheral wall of one end of the second rod body 102 away from the flexible hose 103, and the womb lifting cup 105 can be detached, so that the womb lifting cup 105 with a proper size can be selected according to the body structure of the patient. In order to facilitate the installation and the disassembly of the uterine-lifting cup 105, one end of the second rod body 102, which is far away from the flexible hose 103, is sleeved with a uterine-lifting cup seat 104, and the uterine-lifting cup 105 is clamped on the uterine-lifting cup seat 104 and can be disassembled; in order to facilitate the position adjustment of the uterine cavity lifting cup 105, a first external thread is arranged at one end, far away from the flexible hose 103, of the second rod body 102, the uterine cavity lifting cup seat 104 is sleeved on the second rod body 102 and is in threaded connection with the first rod body 101 through the first external thread, and the length of the first external thread is larger than that of the thread on the uterine cavity lifting cup seat 104, so that the uterine cavity lifting cup seat 104 can move a distance on the second rod body 102, and the position of the uterine cavity lifting cup 105 on the second rod body 102 is convenient to adjust.
The first sliding rod 203 is arranged in the first rod body 101 in a sliding way, the second sliding rod 204 is arranged in the second rod body 102 in a sliding way, and one end, close to each other, of the first sliding rod 203 and the second sliding rod 204 is positioned in the flexible hose 103 and is hinged; the first adjusting mechanism is used for enabling the first sliding rod 203 to slide along the first rod body 101 so as to change the hinge point position of the first sliding rod 203 and the second sliding rod 204; the second adjusting mechanism is used for controlling the second sliding rod 204 to swing, and further drives the second rod 102 to swing so as to adjust the position of the uterus.

The following describes the principles and operation of the present invention in detail with reference to the above embodiments:
when laparoscopic surgery is performed (omitting a preparation part of laparoscopic surgery), firstly, the vulva and the vagina of a patient are cleaned, the vaginal of the patient is opened by using a vaginal speculum, the uterine depth of the patient is measured by using a probe, the cervical width of the patient is observed, the uterine-lifting cup base 104 is rotated, the height of the uterine-lifting cup base 104 from the top end of the uterine-swinging rod 106 is adjusted by threads to adapt to the uterine depth of the patient, then, a uterine-lifting cup 105 which is adaptive to the cervical width of the patient is selected and mounted on the uterine-lifting cup base 104, the uterine-lifting cup 105 is of a non-closed hollow structure, passivation treatment is performed on all edges and corners, and the purpose is to facilitate the observation of the position of the device in the vagina of the patient, to directly see whether the cervix completely enters the cup or not, and to facilitate the taking out of the resected uterus from the vagina (if hysterectomy is performed).
The device is sent into the vagina of a patient, and in the process of sending the device, the vagina sealing balloon 301, the main uterine cavity supporting balloon 303 and the auxiliary uterine cavity supporting balloon 305 are all in an uninflated state, wherein when the auxiliary uterine cavity supporting balloon 305 is in the uninflated state, the top of the auxiliary uterine cavity supporting balloon 305 is completely attached to the top end of the uterine cavity swinging rod 106 due to the tensile force of the tension spring 311 on the rubber partition 307, so that the whole uterine cavity swinging rod 106 and an accessory part can conveniently pass through a cervical orifice.
After the uterine cavity-swinging rod 106 completely enters the uterus of a patient, the top of the uterine cavity-swinging rod 106 is propped against the top of the uterus of the patient, and the uterine cavity-lifting cup 105 seat is completely attached to the cervix of the patient, the main uterine cavity-supporting balloon 303 and the auxiliary uterine cavity-supporting balloon 305 are inflated through the second inflation tube 304 and the third inflation tube 306, and the auxiliary uterine cavity-supporting balloon 305 is inflated, as shown in fig. 2 and 4, the top of the auxiliary uterine cavity-supporting balloon 305 is spaced from the top of the uterine cavity-swinging rod 106 by a certain distance, so that the top of the uterine cavity-swinging rod 106 is prevented from damaging the inner wall of the uterus of the patient in the operation process. Then, the rotary wire wheel 310 is operated to enable the rubber diaphragm 307 to move on the axis of the uterine cavity swinging rod 106, so that the expansion range of the main uterine cavity supporting balloon 303 and the auxiliary uterine cavity supporting balloon 305 is adjusted, the inflated main uterine cavity supporting balloon 303 and auxiliary uterine cavity supporting balloon 305 are enabled to be more attached to the shape of the uterine cavity of a patient, and further the main uterine cavity supporting balloon 303 and the auxiliary uterine cavity supporting balloon 305 are enabled to be basically and completely attached to the uterine cavity of the patient without causing excessive compression on the inner wall of the uterine cavity of the patient.
Then take out and peep the vaginal speculum, inflate the operation to the sealed sacculus 301 of vagina through first gas tube 302, make sealed sacculus 301 of vagina expand to be laminated, form airtight environment with patient's vaginal wall is basically complete, and can not cause too big oppression to patient's vaginal inner wall, accomplish the support work of placing of this device at patient's uterus.
Then, the trigger 205 and the deflation button 206 are operated to perform inflation and deflation operation on the first pneumatic cylinder 201, so that the hinge point of the first sliding rod 203 and the second sliding rod 204 moves on the axis of the central guide rod 100, the knob gear 208 is finely rotated, the change amplitude of the uterine position is observed from the laparoscope display screen, the trigger 205 and the deflation button 206 are continuously used to adjust the hinge point of the first sliding rod 203 and the second sliding rod 204 until a structure curve fitting the patient is found, the precision is proper, the position which does not cause excessive compression on the patient is matched with the doctor of the main knife, and the follow-up operation is performed until the operation is completed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
