Description

Uterine manipulator with adjustable angle

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a can regulate and control palace ware of lifting of angle.

Background

With the development of laparoscopic techniques, almost all gynecological laparotomy operations are now replaced, and hysterectomy is one of the most performed gynecological operations. When the uterus is removed under the laparoscope, an assistant needs to put the uterus into the vagina and lift the uterus by using the uterus lifter, and the uterus lifter is operated according to the instruction of a main surgeon to expose the dissection and operation visual field around the uterus.

Most of the existing uterine lifters are put into the uterine cavity by a straight metal rod, are fixed by screwing a tapered screw on the uterine cavity into a cervical canal, and lift the uterus by a uterine lifting cup fixed on the metal rod. The uterus can not move back and forth by taking the vagina-cervix connecting part as a fulcrum, only the vulva-vagina orifice as a fulcrum is used for lever-like movement back and forth, the uterus is limited by the bone property of the pelvis, the pubic symphysis is arranged in the front, the sacrococcygeal bone is arranged in the back, if an obese patient is touched, the space is more limited, and the uterus can not be well swung back and forth when being lifted; the operation of the uterine cavity and the rectum which are stuck to the back wall of the uterine body cannot reach good exposure space and tension, which brings difficulty and risk to the operation; in laparoscopic wide descending total uterus or other complex hysterectomies, when separating the gap between the rectum and the sacral ligaments and the posterior vaginal wall, the operation visual field is limited, and the operation time and difficulty are increased because the uterus and the cervix cannot sufficiently keep the anteversion anteflexion angle. The rodlike metal uterine lifting rod also often causes uterine perforation, even further damages important organs of the pelvic cavity, including exposed great vessels after cleaning pelvic lymph nodes, and on the other hand, can also cause tumor cells to enter the pelvic cavity from uterine lacerations to cause iatrogenic tumor dissemination. The mode of the taper thread screwed into the fixed uterine lifter of the cervical canal is often difficult to be effectively implemented because the cervix of the elderly women is seriously atrophied or the cervix is already flattened after the cervical operation, and the cervical carcinoma operation extrudes tumor tissues, so that tumor cells are extruded into the peripheral vascular system or tumor tissue fragments fall off to leave the vagina, and the tumor-free principle of the tumor operation is violated.

The solution described above improves to some extent some of the problems of the prior art, but it also has at least the following drawbacks: the operative visual field near the uterus has poor exposure angle, and the uterus is easy to perforate.

Disclosure of Invention

The utility model aims at the above problems and provides an angle-adjustable uterine manipulator which has good operation visual field beside the uterus and is not easy to perforate the uterus.

In order to achieve the above purpose, the utility model adopts the following technical proposal: this can regulate and control uterus lift of angle, including lifting the palace pole, the front end of lifting the palace pole be equipped with and form and stretch out in the uterus lifting binding clip of lifting the palace pole by two binding clip monomers are articulated mutually, the rear end be connected with through the binding clip connecting pipe and control the body, just control on the body and lift and be equipped with the pincers body control mechanism that can control two binding clip monomers and open or fold between the palace pole, lift the articulated setting mutually of palace pole and binding clip connecting pipe, just control and still be equipped with between the body and the uterus lifting pole and control the swing control mechanism that can control the relative binding clip connecting pipe wobbling of uterus lifting pole.

In the uterine manipulator with the adjustable angle, the forceps body control mechanism comprises a forceps rod pull rod which is arranged in the uterine lifting rod and can axially and repeatedly move relative to the uterine lifting rod, the front end of the forceps rod pull rod is hinged with two opening connecting rods, the rear ends of the two forceps head monomers are hinged with the two opening connecting rods, the two forceps head monomers are hinged with the two opening connecting rods to form a parallelogram, and an opening and closing supporting assembly is further arranged between the two forceps head monomers. The front end of the opening connecting rod is hinged with the rear end of the tong head monomer, so that the two tong head monomers can be pulled to open along with the backward contraction of the tong rod pull rod, and the tong head monomers can be pulled to close on the contrary.

In foretell uterus lifter of adjusting and controlling angle, pincers body control mechanism still including connecting at the binding clip pull rod rear end and be located the binding clip connecting tube the binding clip strut directional stick, the binding clip strut the front end of directional stick and link to each other through the rear end of wire rope with the binding clip pull rod, the binding clip strut the rear end of directional stick solid link in setting up in controlling the internal ball seat that can control a body axial reciprocating motion relatively, the rear end of ball seat even have the directional cover of pull rod, the directional cover of pull rod wear to establish in the pull rod position sleeve, just pull rod position sleeve all control the body lock relatively in axial and circumferential direction, control the body on still be equipped with the binding clip drive control subassembly that can drive the directional cover axial motion of pull rod. The two ends of the steel wire rope are fixedly connected with the clamp rod pull rod and the clamp rod stretching and orienting rod respectively, when the clamp rod stretching and orienting rod of the clamp rod moves backwards in the axial direction, the steel wire rope pulls the clamp rod pull rod to move backwards, and preferably, the clamp rod pull rod has a forward movement trend; the pull rod positioning sleeve is used for fixing the pull rod orientation sleeve to prevent the pull rod orientation sleeve from generating lateral deviation, and the clamp rod stretching orientation rod is pulled by the ball head seat.
