Description

Technical Field

[0001] The utility model relates to the field of surgical instruments related to vaginal hysterectomy, and is a traction device for optimizing the exposure of the surgical field, in particular to a traction device for exposing the surgical field of vaginal hysterectomy. Background Art

[0002] Vaginal hysterectomy is a surgical method for total hysterectomy via vaginal approach and is widely used in clinical practice. However, since the patient's surgical position is lithotomy position, the surgeon is located between the patient's legs, and other surgeons have limited space to cooperate or cannot directly see the surgical field. It is difficult to effectively expose the surgical field using traditional retractors, and it occupies the already limited operating space for the surgeon, greatly affecting the progress of the operation. Summary of the invention

[0003] In order to achieve good exposure of the vaginal hysterectomy visual field, optimize the operating space of the surgeon, and improve the quality of surgical cooperation of the cooperating surgeon, this vaginal hysterectomy retractor is designed.

[0004] 1. The technical solution adopted by the utility model to solve its technical problems is composed of a support frame, a Y-shaped support frame connecting rod, a traction frame, a hook, a buckle, and a fixing belt. The support frame is composed of a support frame crossbeam, a support frame vertical beam, and a fixing belt guide groove. The Y-shaped support frame connecting rod is composed of a hook, a retractable rod body, a spring clip, and a serrated adjustment groove. The traction frame is composed of an elliptical slide rail, the hook is composed of an L-shaped hook body, a hook hollow guide rail, and a transverse protrusion on the lower surface of the hook. The buckle is composed of a buckle nut, a downward pressure handle, a buckle transverse protrusion, a buckle screw, and a buckle ring. The fixing belt is composed of a belt body and a front end ring of the fixing belt. The support frame, the Y-shaped support frame connecting rod, and the fixing belt jointly maintain the stable position of the traction frame, and the buckle can adjust and fix the position of the hook to constitute the utility model.

[0005] 2. The support frame is made of stainless steel and consists of a support frame crossbeam, a support frame vertical beam, and a fixed belt guide groove. It is divided into an upper support frame and a lower support frame. The crossbeam length of the upper support frame is 70 cm, the diameter is 2 cm, and the vertical beam length is 60 cm, the diameter is 2 cm. The crossbeam length of the lower support frame is 70 cm, the diameter is 2 cm, and the vertical beam length is 30 cm, the diameter is 2 cm. The vertical beams on both sides of the support frame are connected to the inherent side rails on both sides of the operating table through sliders, and the crossbeams are connected to the hook at the end of the Y-shaped support frame connecting rod.

[0006] 3. The Y-shaped support frame connecting rod is made of stainless steel and consists of a hook, a retractable rod body, a spring clip, and a serrated adjustment groove. It is divided into an upper Y-shaped support frame connecting rod and a lower Y-shaped support frame connecting rod. The length of the rod body can be adjusted by the spring clip. The length adjustment range of the upper Y-shaped support frame connecting rod is 20-30 cm, and the length adjustment range of the lower Y-shaped support frame connecting rod is 10-20 cm. There are 5 / 8 arc hooks at both ends. The head end hook is connected to the elliptical traction frame, and the tail end hook is connected to the support frame beam.

[0007] 4. The traction frame is an elliptical hook traction frame made of stainless steel. The upper and lower diameters of the ellipse are 30 cm, and the left and right diameters are 20 cm. Its cross-section is a gear shape with a diameter of 1 cm, which can prevent the hook fixed on it from axial rotation.

[0008] 5. The retractor is made of stainless steel and consists of an L-shaped retractor body, a hollow guide rail, and a horizontal protrusion on the lower surface of the retractor. The longitudinal retractor handle is 25 cm long and 3 cm wide, the hook end is 15 cm long and 2.5 cm wide, and the hollow guide rail is 1 cm wide. The horizontal retractor handle is 10 cm long and 3 cm wide, the hook end is 15 cm long and 2.5 cm wide, and the hollow guide rail is 1 cm wide.

[0009] 6. The buckle is made of stainless steel and consists of a buckle nut, a push-down handle, a buckle lateral protrusion, a buckle screw, and a buckle ring. The hook or the front end ring of the fixing belt can be fixed on the traction frame. The middle of the buckle ring is hollowed out in the shape of a gear, which matches the shape of the gear of the traction frame to maintain the stable position of the hook. The buckle lateral protrusion prevents the hook from displacement.

[0010] 7. The fixing strap has a loop structure at the front end, and is divided into an upper fixing strap and a lower fixing strap. The loop at the front end is fixed to the buckle. After passing through the fixing strap guide groove on the support frame upward or downward, it is fixed on the side rail of the operating bed. It is 100 cm long, 3 cm wide, and 0.2 cm thick. It is made of cotton cloth and needs to be sterilized before use.

[0011] During clinical use, after the patient is placed in the lithotomy surgical position and before the surgical disinfection, the upper support frame is installed perpendicular to the direction of the operating table at the patient's abdomen, and the lower support frame is installed parallel to the direction of the operating table at the position below the patient's buttocks. After the operation is completed, disinfected and draped, the tail end hook of the Y-shaped support frame connecting rod is connected to the support frame crossbeam, and the traction frame, buckle, retractor and fixing belt are assembled on the surgical instrument table, and the assembled traction frame is connected to the head end hook of the Y-shaped support frame connecting rod. After the fixing belt passes through the fixing belt guide grooves at both ends of the support frame, it is handed over to the circulating nurse under the table to fix the fixing belt to the side rail of the surgical bed.

[0012] The positive effects of the utility model are:

[0013] 1. The utility model has a simple structure and is easy to operate.

[0014] 2. The support frame and traction frame equipped in the utility model can realize the adjustment and fixation functions of the retractor, which can ensure good exposure of the surgical field on the one hand and optimize the operating space of the surgeon on the other hand.

[0015] 3. The gear-shaped structure of the traction frame and the gear-shaped central control design of the buckle equipped in the utility model can realize the axial adjustment and fixation of the pull buckle, avoiding the problem that the doctor has difficulty in maintaining a stable posture for a long time when pulling the hook.

[0016] 4. The telescopic supporting connecting frame equipped in the utility model can also adjust the posture of the traction frame by adjusting the length. BRIEF DESCRIPTION OF THE DRAWINGS
