Description

Complete surgical scissors for uterine septum

Technical Field

The application relates to the field of medical equipment, in particular to a pair of complete uterine septum surgical scissors.

Background

The uterine septum is the most common female genital tract deformity in clinic, and accounts for 80% -90% of uterine deformity, and the probability of infertility, such as repeated abortion, premature birth, premature rupture of fetal membranes, and intrauterine death, etc., caused by the uterine septum is higher than that of normal pregnant women, and the incidence rate of the uterine device in infertility people is 17.9%. The uterine septum is divided into an incomplete septum and a complete septum, the latter accounting for 14% -17% of the septum, depending on the morphology of the septum tissue and the attachment location of the septum tip.

Hysterectomy is a standard treatment of the uterine septum with the aim of resecting or isolating the septum tissue and restoring the normal anatomical morphology of the uterine cavity. The complete septum is cut or separated from the endocervical level, and the septum tissue is dissected laterally into the contralateral uterine cavity and then manipulated in a subseptal manner. The septum of the cervical canal portion is often not resected to avoid damage to cervical function.

In the complete uterine septum, the partial complete septum is provided with a small hole at the position close to the internal cervical orifice so as to lead the uterine cavities at two sides to be communicated, and the operation can be carried out so that the small hole starts to cut off the septum upwards; the part of the septum is completely free of traffic channels, and the septum needs to be penetrated by a special method, enters the contralateral uterine cavity and then is separated towards the uterine undercut. Since the hysteroscope is positioned in one uterine cavity and cannot see the opposite uterine cavity, how to accurately cut the uterine septum without cutting into the anterior wall or posterior wall muscle layer is a difficult problem of operation.

The most commonly used method at present: after one side of cervical canal is expanded, the uterine cavity is placed into a hysteroscope, a Foley catheter is placed into the uterine cavity at the other side of the uterine cavity, 4-5ml of liquid is injected into the balloon, so that the uterine septum is stretched and thinned, and then an electrode is used for cutting a small hole on the level of the cervical internal opening under the guidance of B ultrasonic, so that the balloon of the catheter at the opposite side is exposed, and the uterine cavities at the two sides are communicated.

However, when the septum is thicker, it is still difficult to achieve accurate dissection to form the traffic channel. The common surgical scissors can cut off a part of the septum, and the complete septum is changed into incomplete septum, but the defect is that the selective cutting is not performed, and the septum in the cervical canal and the septum in the uterine cavity are cut off together in the use process, so that the postoperative iatrogenic cervical insufficiency of a patient can be possibly caused. There is no simple, economical, accurate and rapid method at home and abroad to penetrate the septum at the cervical internal orifice and retain the septum at the cervical canal part.

In view of the above, in order to further improve the hysteroscopic complete hysterectomy, further reduce the difficulty of the operation, further improvements in the surgical tools are necessary.

Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

The embodiment of the application relates to scissors used for complete uterine septum surgery, which are used for penetrating a septum at an internal cervical orifice. Referring to fig. 1 to 5, the full-uterine septum surgical scissors according to the embodiment of the present application comprise a pair of symmetrical scissors elements 1 and 2 riveted to each other by a rotation shaft 3.

In the embodiment of the application, the scissor element 1 and the scissor element 2 are mutually cross-riveted through the rotating shaft 3, so that the scissor element 1 and the scissor element 2 can move between an open state (shown in fig. 2) and a meshed state (shown in fig. 1 or 5). The occluded state includes at least partial occlusion and complete occlusion.

In the embodiment of the present application, the inner sides of the scissor element 1 and the scissor element 2 are arranged in a manner of facing each other from the caulking portion (i.e., the rotating shaft 3) to the scissor head 6: a groove 4 and a blade 5. The groove 4 has the function of protecting the septum of the cervical canal part, which is not resected, reducing the occurrence of iatrogenic cervical insufficiency.

In the embodiment of the application, the length of the groove is 3cm (30 mm in the figure), and the depth of the groove is 0.5cm (5 mm in the figure). The length of the groove 4 is designed to be 3cm and the depth is designed to be 0.5cm according to the normal female cervical canal which is generally 3 cm.

In an embodiment of the application, when the scissor element 1 is at least partly or fully engaged with said second scissor element, the two opposing grooves 4 form a compartment for the compartment of the cervical canal part, and the two opposing blades 5 interact to shear the compartment of the uterine cavity part.

In some embodiments, referring to fig. 1-5, the outer sides of the scissor heads 6 are rounded to prevent damage to other structures within the uterine cavity during shearing of the septum of the uterine cavity portion. The length of the blade is 1 cm (10 mm in the figure), so that the excessive excision of the septum into the myometrium is prevented, and the occurrence of complications in the operation is reduced. In some embodiments, the radius of the bullnose of the rounded structure of the scissor head 6 is 0.25 cm (2.5 mm in the figures).

In some embodiments, the scissor heads 6 are rounded structures, the length of the blade is 1cm, other structures in the uterine cavity can be prevented from being damaged in the process of shearing the septum of the uterine cavity part, and the septum is prevented from being excessively resected to cut into the myometrium, so that the occurrence of complications in operation is reduced.

In some embodiments, as shown in fig. 5, when scissor element 1 is fully engaged with scissor element 2, two opposing grooves 4 form a septum space of 0.4 cm (4 mm in the figures) in width for the septum of the cervical canal portion.

In some embodiments, as shown with reference to fig. 1-5, the groove 4 is filleted at both ends. In some embodiments, as shown in FIG. 3, the radius of the fillet of the groove 4 is 0.5 cm (5 mm in the figure). The groove 4 is a fillet, which is stronger than a rectangle, so that the two ends of the groove 4 are not easy to break when being snapped.

In some embodiments, as shown in fig. 4, when the scissors extend into uterine cavities at two sides, the distance between the outer edges of the two scissor heads 6 is 2.35 cm (23.5 mm in the figure), and the distance between the two knife edges at one side of the groove is 0.5 cm (5 mm in the figure).

In some embodiments, the blade 5 is in the shape of a straight line or an arc.

According to the embodiment of the application, the inner sides of the two symmetrical scissor elements 1 and 2 are oppositely provided with the grooves 4, and the length of the grooves 4 is 3cm and the depth is 0.5cm according to the common length of a normal female cervical canal; in addition, the groove 4 with the shape of the fillet is firmer than a rectangle, so that the two ends of the groove 4 are not easy to break when being snapped. When the cervical canal on two sides of the middle partition is expanded to the number 10 of the expansion strip, the scissors are opened as shown in fig. 4, the scissors are respectively stretched into the uterine cavities on two sides, one end of the groove 4 is positioned at the external orifice of the cervix to start shearing, the middle partition of the cervical canal part is just placed in the groove 4 during occlusion, and the knife edge 5 can more accurately and rapidly cut a 1cm incision on the middle partition of the uterine cavity part above the level of the internal orifice of the cervix, so that the uterine cavities on two sides are communicated, which is equivalent to changing the complete middle partition into an incomplete middle partition, and is beneficial to the middle partition excision under the hysteroscope on the next step. Meanwhile, the middle septum of the cervical canal part is protected, so that the cervical canal part is not resected, and the occurrence of iatrogenic cervical insufficiency is reduced. The scissors head 6 is of a round angle structure, the length of the cutting edge 5 is 1cm, other structures in the uterine cavity can be prevented from being damaged in the process of shearing the septum of the uterine cavity part, and the septum is prevented from being excessively resected to be cut into the myometrium, so that the occurrence of complications in operation is reduced.
