Description

TECHNICAL FIELD

[0001] The utility model relates to a vaginal dilator, in particular to a clinical trigger illumination type vaginal dilator, belongs to medical instrument technical field. BACKGROUND

[0002] The vaginal dilator is a common medical instrument in gynecology, mainly used for gynecological examination, operation and treatment. The traditional vaginal dilator is usually made of metal or plastic, with biocompatibility and durability. They usually adopt a duckbill structure, including an upper dilating part and a lower dilating part, connected by a hinge. The upper dilating part includes an upper duckbill piece and a push handle, and the lower dilating part includes a lower duckbill piece and a handle. By pressing the push handle, the upper dilating part rotates around the hinge shaft, so that the upper duckbill piece and the lower duckbill piece open or close.

[0003] However, the existing vaginal dilator has some technical problems in clinical operation. First of all, the surgical field is often dim during transvaginal surgery, and an additional light source is needed to brighten it. The existing technology solves this problem by inserting an independent light source into the operation window, but this will affect the surgeon's operating space and operating action. Secondly, in gynecological surgery, especially in laser surgery and LEEP surgery, smoke will be generated, and the assistant needs to insert an air guide tube into the operation window to assist air guidance. However, due to space limitations, this operation will affect the doctor's operation and may result in poor air guidance, affecting the efficiency of the operation.

[0004] In order to solve these problems, the technical personnel put forward a vaginal dilator with light source, which increases the external LED light source structure in the dilator to brighten the surgical field. However, this design has technical problems, such as the doctor needs to turn on and off the light source through the light source control switch, which needs the assistant to operate when the doctor's hands are busy, increasing the operation complexity and may affect the fixed position of the vaginal dilator. For the air guidance problem, the technical personnel put forward a vaginal dilator with air guidance function, such as Chinese utility model ZL 201920947161.X, which integrates the air guide tube on the vaginal dilator to perform smoke suction during the operation. However, this design is relatively high in cost, and for gynecological examination without air guidance, it will increase the medical cost of the patient.

[0005] Therefore, how to solve the problems in the prior art, especially without affecting the efficiency of the operation and the cost of the patient, is still a hot spot for technical personnel in the field to study. SUMMARY
