Description

Hysteroscopic cervical fixation sealing forceps

technical field

The utility model relates to a medical device, in particular to a device for gynecological examination and operation.

Background technique

With the advancement of science and technology, gynecological hysteroscopy and treatment operations have developed greatly, and have played an important role in the minimally invasive diagnosis and treatment of uterine cavity diseases. Due to the need for fluid to expand the uterine cavity during hysteroscopy and surgery Therefore, if the cervix is too tight, the hysteroscope cannot enter, and if the cervix is too loose, the uterine distension fluid will overflow, which will not effectively expand the uterine cavity, making surgery difficult, prolonging the operation time, and increasing the risk of surgery. The structure of the cervical forceps in the prior art is that the forceps heads at both ends are hook-shaped, and there are longitudinal tooth patterns on the end faces of the hook-shaped structure. If the cervix is too loose or the uterine diameter is too small, it cannot be clamped, and the uterine distention fluid overflows, resulting in poor surgical results, and even difficult surgery.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail. As shown in Figure 1, the hysteroscopic cervical fixation sealing forceps of the utility model is provided with a female lobe 1 and a male lobe 2, and the middle part of the female lobe 1 and the male lobe 2 is a thin rod, and the front end of the two thin rods is at 1/3 length. Hinged via hinge axis 3. The rear end of the thin rod part of the female leaf 1 is connected with an annular first finger ring 7, and the connection between the front end of the first finger ring 7 and the rear end of the thin rod part of the female leaf 1 is provided with a first strip-shaped toothed ring. Tooth buckle 8, the front end of female leaf 1 thin bar is provided with the first clamping tooth 9 that bends 90 °, and the end of this first clamping tooth 9 has tooth pattern. The rear end of the male leaf 2 thin rod is connected with an annular second finger ring 10, and the connection between the front end of the second finger ring 10 and the rear end of the male leaf 2 thin rod is provided with a toothed and strip-shaped first ring. Two tooth buckles 14, the tooth surface of the second tooth buckle 14 is opposite to the tooth surface of the first tooth buckle 8, the front end side of the male leaf 2 thin rod parts is provided with the second clamping teeth 11, the second clamping teeth 11 and the first tooth buckle 8 The tooth surfaces of clip teeth 9 are opposite. The operator passes through the first finger ring 7 and the second finger ring 10 with different fingers, and operates the thin rod part of the female leaf 1 and the male leaf 2 to rotate around the hinge axis 3. When the front ends of the female leaf 1 and the male leaf 2 thin rod parts are closed, the first The two clamping teeth 11 are engaged with the teeth pattern of the first clamping teeth 9, and can be used to clamp the anterior or posterior lip of the cervix. The first tooth buckle 8 is engaged with the second tooth buckle 14, and the female lobe 1 and the male lobe 2 are positioned on the the state. The male leaf 2 is provided with a push rod 5, and the push rod 5 can move along the thin rod of the male leaf 2.

As shown in Figure 2, the rear end of the thin rod of the male leaf 2 is provided with a first limit sliding tooth 13 along the rod, and the rear part of the second clamping tooth 11 at the front end of the male leaf 2 and the thin rod of the male leaf 2 Hollow sliding sleeves 6 are respectively provided at the rear, and the two sliding sleeves 6 are arranged coaxially.

As shown in Figure 3, the push rod 5 is a thin rod part with the same length as the male leaf 2 thin rod part, and its front end is provided with a semi-conical cervical plug 4 made of silica gel material, and the cervical plug 4 is a small semi-conical plug. The end is facing forward, and the rear end of the push rod 5 is connected with a slide button 12 whose cross-sectional size is larger than the thin bar. One side of the slide button 12 is provided with a second limit sliding tooth 15 . The thin rod part of the push rod 5 is assembled into the hollow sliding sleeve 6, and can slide along the male lobe 2. The sliding sleeve 6 restricts and guides the movement of the push rod 5.
