Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a U-shaped frame dedicated to intrauterine micro forceps / scissors. Background Art

[0002] Hysteroscopy is a commonly used technology in the field of gynecology. It is known as the "gold standard" for diagnosing intrauterine lesions and has penetrated into multiple obstetrics and gynecology fields. There are many varieties of hysteroscopic surgical instruments with delicate and complex structures. During secondary use, bacteria and human tissues remaining on the instruments will enter the body of the surgical patient, resulting in an increased infection rate. A very small amount of virus-containing blood (0.0004ml) is infectious. Micro forceps and micro scissors are the most frequently used among all hysteroscopic supporting instruments. Due to their special structure, they cannot be disassembled, the grooves and teeth are narrow, and the joints at the ends of the forceps are tightly closed and cannot open automatically. They are very easy to hide and adhere to contaminants such as blood and body fluids, making cleaning more difficult. At present, the cleaning and disinfection of hysteroscopic micro forceps and micro scissors mostly adopts a combination of manual cleaning and mechanical cleaning and disinfection. Relying on a manual soft-bristle brush to clean stains, some small gaps are not cleaned thoroughly, affecting the cleaning efficiency. Although there are U-shaped frames designed on the market, such as Figure 1 As shown, the existing U-shaped frame is formed by bending a steel bar, which can only be used for fixed models of instruments. However, there are many types of instruments used in the surgical process, and different types of U-shaped frames must be equipped, which not only wastes resources, but also requires selection during use, resulting in reduced work efficiency. The U-shaped frame dedicated to intrauterine micro-forceps / scissors is an auxiliary tool for placing and fixing hysteroscopic instruments. It adopts a U-shaped design, which can effectively open and fix surgical instruments, improve the qualified rate of instrument cleaning, and prevent instruments from sliding or tipping over. At the same time, the U-shaped frame can also reduce the burden on staff and improve work efficiency. However, the current U-shaped frame dedicated to intrauterine micro-forceps / scissors has a single structure, and the size of surgical instruments has become increasingly unable to meet the requirements of full placement and space saving, and the surgical instruments need to be reopened during the cleaning process, which is extremely inconvenient to clean, and medical staff cannot make full use of time. Therefore, it is extremely necessary to have a special U-shaped frame that can effectively fix surgical instruments, prevent instruments from sliding or tipping over, and facilitate the cleaning of surgical instruments at the same time, saving time for staff. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a special U-shaped frame for intrauterine micro forceps / scissors, which can hold a variety of surgical instruments at the same time and can be adjusted according to needs.

[0004] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0005] The utility model proposes a U-shaped frame dedicated to intrauterine micro forceps / scissors, comprising a U-shaped frame, wherein the vertical arm of the U-shaped frame is composed of a first connecting arm and a second connecting arm, the horizontal arm of the U-shaped frame has an inclination angle with the vertical arm, and the inclination angle is greater than 90° and less than 150°; the lower end of the second connecting arm is hingedly connected to one end of the horizontal arm via a limit screw.

[0006] Furthermore, the lower end of the first connecting arm has a threaded protrusion, and the upper end of the second connecting arm is provided with a groove threadedly connected to the threaded protrusion.

[0007] Further, the inclination angle is 120°.

[0008] Furthermore, an anti-slip protrusion is provided on the inner side of the hinge portion at the lower end of the second connecting arm.

[0009] Furthermore, the upper end of the first connecting arm is a conical structure.

[0010] Furthermore, the column diameters of the first connecting arm, the second connecting arm and the cross arm are 3.5-6 mm.

[0011] The beneficial effects of the utility model are as follows: the utility model is a special U-shaped frame for medical surgical instruments, such as intrauterine micro forceps / scissors, which can be adjusted accordingly according to needs, so as to facilitate the placement of more surgical instruments of different sizes, and can save a lot of time for medical staff when using the U-shaped frame to clean surgical instruments.
