Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a surgical expander. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items, including required computer software, that are used directly or indirectly on the human body; their effectiveness is mainly achieved through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] There are many kinds of medical devices, and in anorectal clinics, surgical dilators are needed to dilate the anus. Anal dilation, also known as anal canal dilation, refers to a method of dilating the anus with fingers or instruments under local anesthesia or general anesthesia. Anal dilation is commonly used in anorectal disease inspection, treatment and postoperative recovery. By dilating the anus, the internal and external sphincters of the anal canal are relaxed, so anal fissures and internal hemorrhoids can be treated. According to the Chinese patent with announcement number CN216060605U, a surgical dilator for clinical use in anorectal department is disclosed, including a truncated cone, a truncated cone upper surface A hemispherical cone head is fixedly connected to the surface, a limit rod 1 is fixedly connected to the center of the lower surface of the conical cone, a limit rod 2 is fixedly connected to the circumferential side of the limit rod 1, and a base is rotatably connected to the lower surface of the conical cone. The lower surface of the conical cone is symmetrically provided with cylindrical holes, and the middle and lower ends of the inner walls of the cylindrical holes are provided with conical grooves. However, in the above patent, when expanding the anus, it is easy to cause damage to the anal canal, and the surgical field cannot be better exposed, which is difficult to observe during anal surgery or rectal surgery. For this reason, we propose a surgical expander to solve the above problems. Utility Model Content
