Problems solved by technology

In practice, it is gradually found that the use of small surgical retractors or rubber sheet traction is simple but the effect is not good enough, and sometimes it affects the stability of the surgical plane
The automatic spreader has a complex structure and is equipped with a driving motor, which is not easy to arrange in the operation area and the operation process, and the equipment is expensive

Embodiment 1

[0039] Embodiment one, such as figure 1 As shown, the microsurgical retractor includes a base plate 10 and a pulling mechanism 2 . The edge a1 of the substrate is a circle, and the enclosed circular opaque area is the spermatic cord tissue placement area A, that is, the surgical field of view. Usually in microsurgery, surgical drape is covered around the patient's operating area, and the side of the substrate 10 facing the surgical drape is provided with a fixing part 11. In this embodiment, the fixing part 11 is a quick-disassembly structure, and a double-sided Adhesive backing is arranged near the edge a1 of the substrate on both sides, and is pasted and fixed with the surgical drape during use. It should be noted that the function of the fixing part 11 in the present invention is to fix the microsurgical retractor at the position required by the doctor, and the fixed connection with the surgical drape is only one of the most common cases.

Embodiment 4

[0048] The difference between the fourth embodiment and the third embodiment lies only in the substrate 10 . Such as Figure 8 and 9 as shown, Figure 8 is a partial side view near the substrate 10; Figure 9 is a schematic diagram of the bottom of the substrate 10 . In this embodiment, the substrate 10 is also a flat plate with a fixed plane made of a translucent material. However, on the bottom surface of the substrate 10, that is, the side facing the surgical drape, a light source 102 is arranged around the area corresponding to the spermatic cord tissue placement area A. In this embodiment, strip-shaped LED light strips are used to fix the opposite sides of the bottom surface of the substrate 10. Edge: a layer of uniform film 101 is attached to the bottom surface of the inner substrate 10 corresponding to the spermatic cord tissue placement area A. If necessary during the operation, turn on the LED light source 102, and the uniform light film 101 will uniformly illumi...

Abstract

The invention provides a microsurgery stretching device, which belongs to the field of surgical instruments and devices. The microsurgery stretching device comprises a base plate and a traction mechanism, wherein a surgical visual area is formed within the edge of the base plate; the bottom of the base plate is provided with a fixing part; the fixing part is used for fixedly connecting the base plate with an operation towel; and the traction mechanism can be fixedly connected to any position, which is near the edge, of the base plate. A doctor operates the traction mechanism to tract adjoiningtissues which need to be kept in a surgical area to different heights and different positions near the edge of the base plate, tissues which need to be operated are exposed in the surgical visual area all the time, so that the doctor can quickly and accurately find an operation position in the visual field of a surgical microscope, accidental injuries are effectively avoided, and surgical efficiency is improved. The microsurgery stretching device has a simple structure and a low cost, can be easily equipped and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of surgical instruments and devices, and in particular relates to a bracket for microsurgical operations. Background technique [0002] Microsurgery is a discipline that studies the use of optical magnification equipment and microsurgical equipment to perform fine surgery. It is a surgical technique that can be used by all surgical disciplines, such as gynecological microsurgery, urological microsurgery, and neuromicrosurgery. Performing operations faster and better is an important requirement for the development of microsurgery. [0003] Taking the current situation of urological microsurgery as an example, varicocele (VC) is a common disease in urology with a relatively high incidence rate. It is more common in young and middle-aged men. The incidence rate of adult male population is about 15%. About 40% of the patients with the disease, and about 20% of the combined pain and discomfort. Varicocele is a pathologic...
