Background technology
Wicresoft is the theory that the surgeon acts on all the time, also is present operating developing direction.The human feared state of mind to wound, and to the favor of the distinctive cosmetic result of Minimally Invasive Surgery, impel the transition of surgical operation, and promote of the differentiation of porous laparoscopic surgery to single-hole laparoscopic surgery from traditional abdominal to the laparoscopic surgery that is described as " revolution for the second time ".Need abdominal part to open 3 ~ 4 holes with traditional laparoscopic surgery, the postoperative scar is obvious, recovers slow, and the characteristics of many complication are compared, and single-hole laparoscopic surgery only just can realize that with a hole Minimally Invasive Surgery that just can finish in original 3 holes operates.Such operation mainly contains following advantage: implement operation by the cicatrix that stays after the closure of the natural duct of this human body of umbilical opening, the umbilical part skinfold can hide otch, thereby reach the purpose of no cicatrix operation, has gratifying cosmetic result, simultaneously can alleviate postoperative pain again, thereby reduce in the art, the consumption of postoperative anesthesia and analgesic.Patient's post-operative recovery is fast, lowers infection risk, few complication, and the hospital stays is short, the also corresponding minimizing of hospitalization cost.Therefore, single-hole laparoscopic surgery is more and more accepted by the patient.The problem that present single-hole laparoscopic surgery is prone to is: " fighting " phenomenon of interference mutually appears in 1. external apparatus and endoscope's shank; 2. the operation technique district is difficult for forming the operation triangle; Influence air-tightness when passing in and out the device maple of different-diameter in the 3. same passage repeatedly.
The utility model content
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of single-hole laparoscopic multichannel device is provided.
The technical scheme in the invention for solving the technical problem is: a kind of single-hole laparoscopic multichannel device, comprise top cover, be furnished with instrument channel and passage on the top cover, it is characterized in that: also comprise the otch retractor, described otch retractor is to be connected with the elastic force film in the middle of two circuluses; Described otch retractor is connected with top cover; Described top cover upper surface is sphere shape, described instrument channel runs through top cover and is exposed to the top cover surface, be the open column shape body, be provided with the sealing backstop in the instrument channel, the sealing backstop comprises elastic sealing ring and anti-gas-leak lobe, the anti-gas-leak lobe is located on the instrument channel inwall, and described instrument channel diameter does not wait.
Be flexible connection between above-mentioned otch retractor and the top cover, and the two connects back maintenance sealing state.
Above-mentioned instrument channel upper end open is the downward frustum of awl point.
Above-mentioned sealing ring is a thermoplastic elastomer (TPE).
Above-mentioned anti-gas-leak lobe is in-line or triangular in shape or rounded.
Above-mentioned otch retractor bottom circulus connects a long band.
Above-mentioned instrument channel has 4.
Above-mentioned instrument channel is 2 of large aperture instrument channel, 2 of small-bore instrument channel.
Above-mentioned instrument channel dot matrix is arranged, and the instrument channel of same apertures is the diagonal angle.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, the top cover upper surface is sphere shape, and surface area strengthens, and the instrument channel number can be 4, and more than plane at present 3 can insert 4 apparatuses simultaneously;
2, the top cover upper surface is sphere shape, and the instrument channel upper end open is the downward frustum of awl point, and apparatus is inserted easily, and the channel-active degree is big, and work angle is reasonable, and the operation technique district easily forms the operation triangle, reduces the phase mutual interference, and motility is good;
3, dicyclo joint sealing backstop has good air-tightness, also is convenient to Fast Installation simultaneously, removes, and is convenient and safe;
4, otch retractor and top cover flexibly connect, and are convenient to this utility model is inserted in the otch.
Description of drawings
Fig. 1 is a side-looking cross-sectional view of the present utility model.
Fig. 2 is instrument channel and the passage distribution schematic diagram overlooked of the present utility model.
Fig. 3 is an instrument channel side-looking cross-sectional view of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments this utility model is further specified.
As shown in Figure 1, this utility model comprises top cover 1 and otch retractor, and described top cover 1 upper surface is sphere shape, is furnished with instrument channel 2 and passage 5 on the top cover 1.Described instrument channel 2 runs through top cover 1 and is exposed to top cover 1 surface, is the open column shape body, and upper end open is the downward frustum of awl point.Because top cover 1 upper surface is sphere shape, instrument channel 2 upper end open are horn-like, and apparatus is entered in patient's body easily by instrument channel 2, and apparatus can be kept at an angle when entering, and make operation more flexible.
Described otch retractor is to encircle 71 on two circuluses, encircle 72 down, and the centre is connected with elastic force film 73.The ring 71 gone up of described otch retractor is connected with top cover 1 lower edge, can be connected to one, also can form to flexibly connect by bayonet socket or helicitic texture, and the two connect after maintenance sealing state.The two is that bayonet socket connects in the present embodiment, on encircle 71 and top cover 1 lower edge junction the elastic force sealant is arranged.The following ring 72 of described otch retractor connects one and longly is with 6, when purpose is to take out this utility model, ring 72 is tilted and is out of shape by the long band of tractive, is beneficial to taking-up.
Shown in Fig. 1,3, be provided with the sealing backstop in the instrument channel 2, the sealing backstop comprises elastic sealing ring 3 and anti-gas-leak lobe 4, described sealing ring 3 is a thermoplastic elastomer (TPE), anti-gas-leak lobe 4 is located on instrument channel 2 inwalls, described anti-gas-leak lobe 4 is in-line or triangular in shape or rounded, and present embodiment anti-gas-leak lobe 4 is in-line.When not inserting apparatus, anti-gas-leak lobe 4 closures; After inserting apparatus, because elastic reaction, sealing ring 3, anti-gas-leak lobe 4 are combined closely with apparatus; After extracting apparatus, under the gas pressure effect, anti-gas-leak lobe 4 closures, sealing ring 3 has the non-return anti-effect of backflowing of good sealing because the elastic reaction retraction has prevented that gas leaks outside in the body.
As shown in Figure 2, described instrument channel 2 has 4, and diameter does not wait.The instrument channel dot matrix is arranged, and 2 large aperture instrument channel 21 can be used for specification instrumentations such as 15mm, 12mm, 10mm, 5mm or 3mm, and 2 small-bore instrument channel 22 are applicable to 5mm or 3mm instrumentation, and the instrument channel of same apertures is the diagonal angle.Passage 5 is the inflation body and function, and its purpose is to set up pneumoperitoneum or aerofluxus.
