Description

Cervical composite forceps holder

Technical Field

The utility model relates to a hysteroscope therapeutic apparatus, in particular to a cervical clamp.

Background

In the process of hysteroscope treatment, the uterus is often loose in the inner opening and the outer opening of the cervix, so that the uterus swelling liquid is easy to leak. If the uterus swelling liquid flows outwards more, the uterus cannot be swelled well, so that the examination and treatment of the hysteroscope are affected, and the external opening of the uterus swelling liquid can be prevented from being leaked greatly by clamping the external opening with cervical clamps. However, the cervical clamps used at present mainly play a role in pulling the cervix during the operation, and only play a part of roles due to the problems of structure for clamping the cervix and preventing the uterine bleeding, and are mainly embodied as follows: the cervical clamp used at present only has one jaw with a fixed bending angle, so that the selection of a proper cervical clamp angle is limited, the range of the clamp is small, and the cervix is easy to slip; although the gripping force can be increased by increasing the number of teeth engaged at the handle to prevent the cervix from slipping, it can cause more damage to the cervix; in addition, cervical clamps are generally long, and the handle of the cervical clamp can affect the operation of the hysteroscope body and other therapeutic devices (e.g., forceps or scissors) during the course of a hysteroscopy procedure.

Chinese patent CN2497728Y discloses a pair of annular-jaw cervical clamps, whose jaws are semi-elliptical, which can keep the cervical canal smooth when the cervix is pulled out, and can also press the cervical canal in the liquid to prevent backflow. However, the semi-elliptical jaw is not beneficial to the operation of clamping the cervix at different angles, and the angle between the handle and the jaw is fixed, which is also not beneficial to the feeding of the cervical clamp.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1, 2 and 3, the cervical external orifice composite forceps of the present invention comprises three parts, namely, an operating handle 1 (with a length of about 12 cm), a forceps body 2 and a sleeve 3. The front end of the forceps body 2 is provided with two arc-shaped jaws 2-2 (with an arc which is approximately equal to 15 degrees and is close to the arc of the cervix), one ends of the two arc-shaped jaws 2-2 are correspondingly connected with two front end force arms of the forceps body 2 through a mandrel 2-1 respectively, the jaws 2-2 are respectively provided with three thorn-shaped objects, and the three thorn-shaped objects can be mutually meshed together when the two arc-shaped jaws 2-2 are folded at the inner sides of the front end force arms. One end of the front end force arm provided with the mandrel 2-1 can refer to the structural form of the front end of the existing cervical clamp with a certain radian (namely the two front end force arms are slightly different in length and slightly bent towards the same side, so that the furling angle of the jaws is larger), the two rear end force arms of the clamp body 2 are connected with the operating handle 1 (the front end force arms and the rear end force arms are bounded by a hinge point of the clamp body 2), the operating handle 1 comprises two rod bodies which can be disassembled or installed at the tail ends of the corresponding rear end force arms of the clamp body 2 through pulling and inserting, a spring chain 1-1 is connected between the two rod bodies, the main function of the spring chain 1-1 is to keep the two rod bodies connected together after being disassembled, so as to avoid losing, and buckling teeth 2-3 which can be matched with each other are arranged on the two; the forceps body 2 can penetrate through the sleeve 3, the sleeve 3 is used for preventing the forceps jaws 2-2 from damaging surrounding tissues in the process that the forceps jaws 2-2 (which can be folded in the sleeve 3) enter a uterine cavity on one hand, and is used for opening the folded forceps jaws 2-2 by a certain angle through back-and-forth movement and pushing in the uterine cavity on the other hand, so that the forceps body 2 drives the forceps jaws 2-2 to clamp the cervix 4 under the driving of the operating handle 1.

After the hysteroscope body enters the uterine cavity, if the situation that the uterine cavity expanding liquid leaks out more and the uterine cavity expanding effect is poor occurs, the cervix is clamped by the forceps, at the moment, the paging speculum is firstly put on, then the forceps are sent into the cervical external opening composite forceps holder (the sleeve is firstly sent into, and the forceps body is quickly sent into by taking the sleeve as a channel), then the forceps jaws 2-2 in the folded state are quickly unfolded (namely rotated by a certain angle) by utilizing the sleeve 3 and the oval forceps and the curved forceps used in the gynecological operation, and the corresponding angles of the forceps jaws 2-2 are adjusted according to the size and the curvature of the cervix 4, so that the cervix 4 can be better clamped. After the sleeve 3 is withdrawn, the operating handle 1 is used for controlling the jaw 2-2 to clamp the cervix 4, at this time, the operating handle 1 can be taken off, and then the paging speculum can be taken off, so that only the tail end of the rear end force arm of the forceps body 2 is exposed, and the force arm of the forceps body 2 is positioned beside the jaw 2-2, therefore, the hysteroscope treatment operation can be continuously carried out (namely, other required instruments are entered for treatment operation). When the cervical external orifice composite forceps holder needs to be withdrawn, the operating handle 1 can be reinstalled, the forceps jaws 2-2 are enabled to release the cervix 4, and at the moment, the forceps jaws 2-2 are folded in the forceps body 2, and the forceps body 2 is pulled out of the sleeve 3 which is placed in the rear edge of the forceps body 2 again.

In a word, the jaw of the cervical external orifice composite forceps of the utility model is outwards inclined and provided with an arc shape, the quantity of thorn-shaped objects on the jaw is more, the cervical orifice composite forceps can adapt to the change of the position angle of the cervix, and the cervix is clamped in a larger area, thereby effectively preventing the liquid from leaking out of the uterus and reducing the damage to the cervix; in addition, the operating handle can be detached, so that the operating space of a doctor is increased and the working efficiency is improved during treatment operation.
