Specific implementation mode

The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made. These belong to the scope of protection of the utility model.

As shown in Figure 1, in embodiment, endoscope sheath provided by the utility model includes to be inserted into tube body 1, head end shell 2 And bending section 3.Wherein, surgical instrument channel, endoscope path way are in axial direction offered as shown in Fig. 2, being inserted into tube body 1 And aqueous vapor channel constitutes tube body through-hole, three channels parallel arrangement of tube body through-hole and not connected, head end shell 2, bending It is provided with head end outer casing through hole 21, bending section through-hole 31 in portion 3, and is corresponded with the channel in tube body through-hole.Use process In, surgical instrument, endoscope, aqueous vapor respectively penetrate operation instrument channel, endoscope path way, aqueous vapor channel, due to aqueous vapor Function is to clear up the watch window of endoscope, therefore endoscope path way is disposed adjacent with aqueous vapor channel.The setting of bending section 3 exists It is inserted into the distal end of tube body 1, in embodiment, bending section 3 is integrally formed with insertion tube body 1, that is to say, that bending section 3 can be with It is to process to be formed as an extension for being inserted into tube body 1；Certainly in preference, bending section 3 can also be with tube body 1 is inserted into Two components arranged side by side, bending section 3 are connected to the distal end for being inserted into tube body 1 by modes such as screw thread, engaging or gluings.Bending Multiple arcs groove is evenly arranged in portion 3 in an axial direction；Multiple arc grooves are interspersed in the circumferential, use process In, the bending for being inserted into tube body 1 is realized by the change of groove gap size.For example, on a section of bending section circumferentially Three arc grooves are evenly equipped with, every arc groove extension angle is slightly less than 120 degree, the arc in axial direction on two adjacent sections Circumferentially angle differs 180 degree between connected in star.Certainly, arc groove can also not interlock in the circumferential, for example, bending section 3 Including two sides, two sides are oppositely arranged, and are evenly equipped with multiple arcs groove on each side in an axial direction, and arc groove prolongs Hade degree is slightly less than 180 degree, and the arc groove on two sides can be one-to-one on axial position, can also be phase Mutually it is staggered.Head end shell 2 is connected with the distal end of bending section 3, as shown in figure 3, end housing through-hole 21 is provided on head end shell 2, The end housing through-hole 21 is corresponded with the channel in tube body through-hole, and aqueous vapor spout 22 is additionally provided on the distal face of head end shell 2, Aqueous vapor spout 22 includes boss, and boss is extended outwardly from 2 distal end of head end shell, boss distal end face closure, is set on boss wall surface It is equipped with radial aperture, radial aperture is communicated with aqueous vapor channel, and radial aperture is towards endoscope path way position, to ensure aqueous vapor The watch window of endoscope can be cleaned to.Rounding off between the distal face and wall surface of head end shell 2, prevents using process In, perienchyma is caused to hurt.In embodiment, head end shell 2 is nested in the outside of bending section 3, and nested mode can be Transition or interference fit can also be to be threadedly coupled, and in contrast, the mode structure of threaded connection is firm, and head end shell 2 is not easy Split away off from bending section 3, from and also dismounting it is more convenient.

In preference, endoscope sheath provided by the utility model can also be comprising insertion tube body 1, and not include head End housing 2 correspondingly needs rounding off between the distal face and wall surface of bending section 3, and the distal face in bending section 3 is directly set Set above-mentioned aqueous vapor spout 22.It can certainly keep the smooth of the distal face of bending section 3 and be not provided with aqueous vapor spout 22, still The cleaning effect of the watch window of endoscope also can phase strain differential.It is further preferred that aqueous vapor channel can also be not provided with, inside peep The structure of mirror mirror sheath is simpler, and manufacturing cost also can be reduced accordingly, suitable for it relatively totally, need not additionally be cleaned in The working environment of the watch window of sight glass.In embodiment, surgical instrument channel is not connected in insertion tube body 1 with endoscope path way Advantage be that it is possible to that operating equipment is effectively prevent to cause to hurt to endoscope in use, in preference, surgical instrument Channel can be intercommunication being inserted into tube body 1 with endoscope path way, and going back endoscope when necessary can be with a certain portion of surgical instrument Divide and be fixed, during use, endoscope follows surgical instrument to move together, convenient that operative site is illuminated and seen It examines, certain surgical instrument channel and endoscope path way can also be partially communicating, such as surgical instrument channel being inserted into tube body 1 It is only detached in the distal end for being inserted into tube body 1 with endoscope path way, thus the relative position in fixed endoscope channel and aqueous vapor channel, Facilitate surgical instrument and while penetrating of endoscope, can also carry out high-efficiency washing to the watch window of endoscope.

The utility model additionally provides a kind of endoscopic system, including above-mentioned endoscope sheath and endoscope, endoscope Detachably it is assemblied in the endoscope path way of endoscope sheath.It is peeped in traditional included surgical instrument channel and aqueous vapor channel Lens device compares, and the surgical instrument channel, aqueous vapor channel of the utility model are arranged in endoscope sheath, and endoscope includes only to take the photograph As system, lighting system, insertion tube etc. are for illuminating, the component of overview function, and endoscope sheath is disposable.Make After endoscopic system provided by the utility model, endoscope is continuing with after can disassembling cleaning and sterilizing, and endoscope Mirror sheath can directly be thrown away, and removed from and cleaned the thin and long surgical instrument channel for being difficult to sterilize, water and gas conduit, and work effect is improved Rate effectively prevent operation cross-infection.In addition, endoscope sheath includes bending section 3, endoscope can be not provided with bent angle and bent angle Then operating system manipulates as long as in use, endoscope to be inserted into endoscope path way and the fixation of disposable endoscope sheath The bending section 3 of disposable endoscope sheath, using the aqueous vapor channel of disposable endoscope sheath, surgical instrument channel, i.e., The institute that conventional endoscope device can be achieved is functional.Certainly, endoscope sheath provided by the utility model can also in tradition Endoscopic device is used cooperatively, for example blocks the aqueous vapor channel of conventional endoscope device when use, and is carried using the utility model Aqueous vapor channel in the endoscope sheath of confession, to eliminate conventional endoscope device aqueous vapor channel cleaning and sterilizing, hospital Workload can be saved in the case where being changed without existing endoscope related medical instrument.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment Sign can be arbitrarily combined with each other.
