Description

Uterus traction device

Technical Field

The utility model belongs to the technical field of draw gear, concretely relates to uterus draw gear.

Background

Cervical cancer is one of the most common malignant tumors in gynecology, and the early operation effect is good. With the development of laparoscopic surgery, laparoscopic surgery for cervical cancer has been widely developed, and in hospitals or departments where laparoscopy is developed to be mature, laparoscopic cervical cancer surgery has greatly exceeded traditional laparotomy. Laparoscopes are increasingly popular with patients and doctors because of their advantages such as clear vision, less bleeding, anatomical positioning, and small scars.

During surgery, it is often necessary to lift the uterus in order to expose the operative field. At present, the uterus is lifted by using the uterus lifting cup in operation, but the violent extrusion and friction of the uterus lifting cup at the top end of the vagina and the local part of a cervical tumor can increase the probability of shedding, planting and spreading of tumor cells, and the possibility of perforation damage of the uterus and the probability of spreading of the tumor cells can also be increased when the uterus lifting cup is arranged or used.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned not enough, the utility model provides a uterus draw gear, the device can effectively solve the current problem that causes the cancer cell to drop easily that lifts the palace cup existence, increases the probability that the cancer cell spreads.

In order to achieve the above object, the present invention provides a technical solution for solving the technical problem:

the utility model provides a uterus draw gear, includes fixed band and fixed the knot, the fixed band with the fixed one end integrated into one piece who detains, fixed band one side is provided with first latch, fixed knot middle part is provided with the passageway, be provided with on the lateral wall of passageway with the second latch of first latch looks interlock, the cross-section of fixed band free end is the triangle-shaped structure, the free end of fixed band is provided with the through-hole, fixed the knot is provided with solid fixed ring, gu be connected with the pull wire on the fixed ring, the free end of pull wire is provided with straight steel needle.

The beneficial effects produced by adopting the scheme are as follows: the fixing band is used for fixing the uterus, during operation, the free end of the fixing band is inserted into the through hole of the fixing buckle, at the moment, the first latch is contacted with the second latch and occluded, the fixing band can move forwards only in one direction, the fixing band forms a circular ring-shaped structure and is firmly sleeved on the uterus to fix the uterus, at the moment, a straight steel needle at the free end of the traction wire penetrates through the abdominal wall skin from the abdominal cavity, then the traction wire is fixed through a larger device with the same volume as an operation clamp, a doctor pulls the traction wire from the outside of the body of a patient, the position of the uterus can be changed, the operation visual field can be conveniently exposed, and the safety of the operation and the operation efficiency are improved; the doctor can also fix the operating forceps in the through hole at the front end of the fixing band to draw the traction device.

Further, the second latch is arranged on one side close to the fixing band.

The beneficial effects produced by adopting the scheme are as follows: the second latch sets up in being close to fixed band one side, and when the fixed band inserted the passageway in, first latch just sets up on the inner wall of the annular fixed band that forms, and fixed back first latch can with uterus in close contact with, increases the frictional force between fixed band and the uterus, avoids the fixed band to drop, improves the result of use.

Further, the fixing ring is provided with 3 sets.

Furthermore, the fixing buckle is of a cuboid structure, and the fixing rings are respectively arranged on two end faces and one side face of the fixing buckle.

The beneficial effects produced by adopting the scheme are as follows: the 3 groups of fixing rings are respectively arranged in 3 vertical directions of the fixing buckles, when the fixing ring is used, the traction wires and the straight steel needles on the fixing rings penetrate out of the abdominal wall from different directions of the abdomen of a patient and are fixed, when the operation visual field of the pelvic cavity on the right side of the uterus needs to be exposed, the traction wires on the left side only need to be loosened, the traction wires on the left side are tightened, the uterus moves towards the left side, the operation visual field of the pelvic cavity on the right side of the patient is exposed, and the operation is convenient to; on the contrary, when the operative vision field of the left pelvic cavity of the uterus needs to be exposed, the uterus moves to the right side only by loosening the traction wire on the left side and tightening the traction wire on the right side, and the operative vision field of the left pelvic cavity of the patient is exposed; similarly, the traction line on the upper side of the uterus is tightened, so that the part between the uterus and the rectum can be exposed, the rectum can be pushed down conveniently, if the tail end of the clamp fixing band is pulled towards the head side, the area between the uterus and the bladder can be exposed, the bladder can be pushed down conveniently, and the operation can be facilitated.

Furthermore, a placing groove is further formed in the fixing buckle, the placing groove and the fixing ring are located in the same plane, a rubber sheet is arranged on the placing groove, and an opening is formed in the middle of the rubber sheet.

The beneficial effects produced by adopting the scheme are as follows: the standing groove is used for placing pull wire and straight steel needle, and the sheet rubber is detained as integrated into one piece with fixed, takes off the sheet rubber by the opening to both sides, take out its inside pull wire and straight steel needle can, this design can improve the convenience when placing the fixed band greatly, avoids the pull wire then to take place around phenomenons such as knoing, improves the result of use.

To sum up, the utility model has the advantages of it is following:

1. this draw gear is provided with fixed band and fixed the knot, is provided with the passageway that is used for placing the fixed band in the fixed knot, is provided with the second latch that is used for card and fixed band in the passageway, and during the use, the fixed band can be along fixed knot unidirectional movement, fixes the uterus, then punctures the stomach wall through straight steel needle, outside alright follow the direction of difference at the abdominal cavity pull the uterus, changes the position of uterus, does benefit to the exposure in the operation field of vision, improves convenience and the security of using.

2. When the traction device is fixed, the traction device is prevented from being in contact with the cervix and the uterine cavity, uterine cancer cells are prevented from falling off due to violent extrusion, the risk of the cancer cells being planted in the abdominal cavity can be greatly reduced, and the use safety is improved.
