Problems solved by technology

[0004] It solves the problem that the existing vaginal retractor is not easy to hold for a long time because the device is wide, and because the tongue is perpendicular to the body, the grip part is affected by the perineum, which is inconvenient to pull open, and the surface is easy to slip and there is reflection under the lamp, etc. defect

Embodiment 1

[0020] Vaginal retractor is an auxiliary surgical instrument used for vaginal surgery, and is often used as an auxiliary tool for vaginal opening exposure during vaginal suturing. The original conventional vaginal retractor is designed in a curved shape with a blood groove. During the operation, because the angle between the handle and the hook tongue is about 90 degrees, the opening range is too small, and the grip part is affected by the perineum, making it inconvenient to operate. The improved original design of the present invention increases the angle between the handle and the tongue of the draw hook, which is convenient for the operation of the assistant. Since the existing vaginal retractors are often provided with blood grooves along the longitudinal direction of the retractors, it is found in practical applications that even if there is blood, it will be sucked away by the suction device at the abdominal incision, so this design has no positive technical effect, and ...

Embodiment 2

[0023] See the attached picture for the specific structure Figure 4 , similar to Example 1, the difference is that the hook handle extension rod 3 is added, and the design of the extension rod of the hook handle extension rod 3 is to enable the surgical assistant to assist the opening of the vagina, and the operating handle should be as far away from the suturing position as possible for the operation. or vacate the suturing operation position. The hook handle 4 adopts a hand-held handle design to ensure a comfortable hand feeling when holding it.

Embodiment 3

[0025] The specific structure is similar to that of Embodiment 2, except that the inside of the retractor handle 4 is hollow, so as to reduce the weight of the overall retractor and facilitate the operation assistant to hold it for a long time.

Abstract

The invention belongs to the field of medical apparatus, and particularly relates to improvement and optimization of gynecological operation apparatus. An improved vaginal tractor includes a tractor tongue (1), a tractor corner piece (2) and a tractor handle (4), and the tractor corner piece (2) is of an obtuse angle of 120 degrees. Further, the improved vaginal tractor is further provided with a tractor handle extension rod (3), and according to the tractor handle (4), a hand-held handle design is adopted; the width of the tractor tongue (1) is smaller than that of the tractor handle (4), the interior of the tractor handle (4) is of a hollow design, skid-resistance treatment is conducted on the surface of the tractor handle (4), matting treatment is conducted on the whole vaginal tractor, and a making material of the whole vaginal tractor is 304 stainless steel. According to the improved vaginal tractor, the angle of the tractor corner piece (2) is increased, it is convenient for surgical assistants to have sufficient adjustment space, and the improved vaginal tractor is suitable for various surgical operation requirements in real time. According to the technical scheme, because the surface of the tractor handle (4) can further undergo the skid-resistance treatment, it is convenient for the surgical assistants to operate. After the matting treatment is conducted on the whole vaginal tractor, the disturbance of reflected light on surgical operators is reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to the improvement and optimization of gynecological surgical instruments. Background technique [0002] Vaginal retractors are the most common surgical instruments in gynecological operations, and are used to pull the vaginal wall and expand the inspection or surgical field of view. Most of the vaginal retractors on the market are shoehorn-like flat structures, characterized by thinness, width, and an angle of 90 degrees between the tongue and the body, and blood grooves along the long axis. Contents of the invention [0003] The technical problem solved by the invention [0004] It solves the problem that the existing vaginal retractor is not easy to hold for a long time because the device is wide, and because the tongue is perpendicular to the body, the grip part is affected by the perineum, which is inconvenient to pull open, and the surface is easy to slip and there is ref...
