Embodiment 1

[0041] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a shadowless incision protector of the present invention. A shadowless incision protector, the shadowless incision protector includes an outer snap ring 1, a channel 2, an inner snap ring 3, and a lighting lamp 4; the outer snap ring 1 is arranged on one side of the channel 2, and the The inner snap ring 3 mentioned above is arranged on the other side of the channel 2; the channel 2 is made of silica gel material or PU material.

[0042] Please refer to figure 2 , figure 2 It is a schematic diagram of the connection relationship between the inner snap ring 3 and the lighting lamp 4 in a shadowless cut protector of the present invention. The inner snap ring 3 includes an upper protruding edge portion 31, a lower protruding edge portion 32, and a concave portion 33; one side of the concave portion 33 is connected to the upper protruding edge portion 31, and the other side of the concave port...

Embodiment 2

[0048] This embodiment is basically the same as Embodiment 1, the difference is that the illuminating lamp 4 in this embodiment is an LED shadowless lamp, and the LED shadowless lamp is constructed by a semiconductor that emits blue light, and the semiconductor that emits blue light is coated with blue light that absorbs and transmits Parts of the phosphor layer fluoresce yellow broadband broadly and thus produce white light by mixing the radiation. The use of LED shadowless lamps has the following advantages: 1. Excellent cold light effect, using LED shadowless lamps as surgical lighting, it is a real cold light source 41, and there is almost no temperature rise in the surgical area; 2. Good light quality can increase blood and other tissues of the human body The chromatic aberration of the organs makes the doctor's vision clearer during the operation, and it is easier to distinguish the various tissues and organs in the incision in the flowing and infiltrating blood.

Embodiment 3

[0050] Please refer to image 3 , image 3 It is a structural schematic diagram of another shadowless incision protector of this embodiment. This embodiment is basically the same as Embodiment 1, the difference being that the illuminating lamp 4 in this embodiment includes a light source 41, a reflective housing 42, an optical integrating rod 43, and a condenser lens 44; the light source 41 is provided with an optical integrating One side and the other side of the rod 43 are connected to the small end of the reflective housing 42 , and the large end of the reflective housing 42 corresponds to a condenser lens 44 .

[0051] The reflective shell 42 is a transparent circular platform, and the reflective shell 42 can lead the light entering from the small end of the reflective shell 42 out from the large end of the reflective shell 42;

[0052] The light source 41 is arranged near the small head end of the reflective shell 42;

[0053] An optical integrating rod 43 is arranged ...

Abstract

The invention relates to a shadow-less incision protector. The shadow-less incision protector comprises an outer clamping ring, a channel, an inner clamping ring and an illumination lamp. The outer clamping ring is arranged on one side of the channel, and the inner clamping ring is arranged on the other side of the channel. The channel is made of a silica gel material or a PU material. The inner clamping ring comprises an upper protruding edge portion, a lower protruding edge portion and a concave portion. The upper protruding edge portion is connected to one side of the concave portion, and the lower protruding edge portion is connected to the other side of the concave portion. The illumination lamp is arranged on the inner surface of the concave portion. The shadow-less incision protector has the advantages that the shadow-less incision protector can provide illumination, a surgical field is not affected and the surgical operation difficulty is reduced while a surgical incision is protected, the surgical operation field under the shadow-less incision protector can be clearer, the surgical safety is remarkably improved, and surgical related complications are decreased. The shadow-less incision protector can become a special medial instrument product and has a wide application prospect in clinic popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a shadowless incision protector. Background technique [0002] The incision of laparoscopic surgery is small, and the passage of laparoscopic instruments into and out of the incision is easily hindered by soft tissues such as muscles in the incision. At the same time, the entry and exit of these instruments can easily damage the muscles, blood vessels and other tissues around the incision. Thereby causing operation inconvenience, incision bleeding and incision tissue damage increase the chance of postoperative incision non-healing and infection. The surgical incision protector can protect the incision and avoid the above situations from happening. [0003] Disposable incision protectors have been widely used in abdominal surgery operations. This device can effectively protect large abdominal incisions during surgery, reduce the chance of postoperative infection, and ...
