Flexible multichannel integratorTechnical field
The invention belongs to the soft apparatus sheath of single-hole laparoscopic pipe research and development technology field, be specifically related to the soft apparatus sheath of a kind of single-hole laparoscopic pipe and connect the flexible multichannel integrator that operating theater instruments is used.
Background technology
Micro-wound surgical operation is meant equipment and technology such as using advanced electronics in the present age, electric heating, optics, replace the naked eyes direct-view, replace finger with the electron mirror picture with elongated implement, make every effort under the lightest stress in the otch path in minimum, minimum tissue injury, human body, finish observation to internal lesions, diagnosis, cut-out and other treatment, to the reconstruction of abnormal structure's organ, have the advantages that operative hemorrhage is few, postoperative pain light, it is fast to recover, wound is tiny, spot is trickle or do not have cicatrix.Because of its wound is little, recover fast, more and more be subjected to patient's favor.
The conventional surgical Minimally Invasive Surgery generally need be opened otch more than 3 on one's body patient, set up hard passage discrete more than 3 by special-purpose laparoscopically surgical operation with apparatus, each passage can only allow single operating theater instruments to enter, and can only allow knee type laparoscopic instrument bar to enter, so not only increased the wound area of operation, and it has strengthened the operation easier of operation.Developed multiple multichannel integrator in succession at the domestic and international associated companies of the problem that traditional micro-wound surgical operation ran in recent years, but mostly be rigid multichannel integrator, the integrated number of passage few (only integrated operating theater instruments bar passage and inlet channel), and rigid passage causes that apparatus bar work angle is little, operation is dumb, generally can only be with expensive curved head type laparoscopic surgery apparatus bar.The present invention therefore.
Summary of the invention
The object of the invention is to provide a kind of flexible multichannel integrator, has solved that the multichannel integrator is the hard passage in the prior art, causes problems such as operating theater instruments bar work angle is little, operation is dumb.
In order to solve these problems of the prior art, technical scheme provided by the invention is:

The specific embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are used to the present invention is described and are not limited to limit the scope of the invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment
Shown in Fig. 1~3, this flexibility multichannel integrator comprisesflexibility platform 1, and theflexible channel 2 that several grip laparoscopic surgical instruments is set on the describedflexibility platform 1, describedflexible channel 2 one ends sealing, and other end opening inserts for laparoscopic surgical instruments.The opening of describedflexible channel 2 is provided withflexible sealing ring 21, and theblind end inwall 22 of described flexible channel is the cambered surface inwall, is tubularchannel side wall 23 between describedflexible channel 2 openings and blind end.
Theinside diameter D 1 of describedflexible sealing ring 21 is less than theinside diameter D 2 ofchannel side wall 23 under the naturalness; And the internal diameter offlexible sealing ring 21 is less than the external diameter of laparoscopic surgical instruments; The internal diameter of describedchannel side wall 23 is greater than the external diameter of laparoscopic surgical instruments.Lining is establishedreinforcement 24 on theblind end inwall 22 of described flexible channel.On the blind end outer wall 25 of described flexiblechannel support arm 26 is set; Describedsupport arm 26 two ends andflexibility platform 1 are fixing.
Describedflexibility platform 1 is provided with 4 flexible channels 2.The laparoscopic surgical instruments bar external diameter difference that describedflexible channel 2 permissions are inserted.Describedflexibility platform 1 is a circular platform, and describedflexible channel 2 forms one withflexibility platform 1, and describedflexibility platform 1 circumferentially is provided with shirt rim 11.Describedflexibility platform 1 is positioned atflexible channel 2 middle parts withflexible channel 2 junctions.Describedflexibility platform 1 is for using the flexibility platform of medical grade silicon rubber, latex preparation; Describedflexible channel 2 is for using the flexible channel of medical grade silicon rubber, latex preparation.
This flexibility multichannel integrator is the special-purpose member of the soft apparatus sheath of single-hole laparoscopic pipe, is applied to laparoscopically surgical operation.This flexibility multichannel integrator can make laparoscopic surgical instruments can move flexibly in passage, and guarantees the sealing of operation path when operating theater instruments plug or operation are moved.
A passage is a laparoscopic surgical instruments bar designated lane in the flexible channel, and all the other are peritoneoscope assistive device designated lane.The laparoscopic surgical instruments designated lane is applicable to that different-diameter conventional laparoscopy operating theater instruments bar enters, and be applicable to conventional straight type, flexure type laparoscopic surgical instruments bar, flexible channel inserts the posterior end in laparoscopic surgical instruments and opens mouthful cross sectional inner diameter greater than the apparatus external diameter.
Flexibility platform 1 is as the supporting surface of operating theater instruments operation; Described flexible channel is used to provide the operating theater instruments operating walk way, the sealing of assurance operation path before operating theater instruments is inserted or after inserting.Describedflexibility platform 1 has shirt rim 11, makes things convenient for its cooperation to grip the miscellaneous part of laparoscopic surgery.Flexible sealing ring 21 becomes 50 degree angles with horizontal plane, its aperture D1 is less than the external diameter that inserts laparoscopic instrument, and flexible sealing ring was close to the apparatus outer wall when apparatus inserted, and reached the effect of sealing.Flexible sealing ring 21 can reset rapidly after apparatus is extracted; The blind end inwall is a cambered surface, and the cambered surface radian is 45 degree, when guaranteeing that the flexible channel inner space is enough big, has also guaranteed the horizontal applied force minimum of flexible channel blind end to the apparatus outer wall, and laparoscopic instrument can be swung in operation path flexibly; Reinforcement is arranged on the blind end inwall, strengthens flexible channel proof pressure and drawing-off intensity; Support arm is arranged at blind end outer wall both sides and is connected with flexibility platform, and the stress of support arm will make that the blind end inwall resets fast, closure after apparatus is extracted.
The present invention is the single-hole laparoscopic micro-wound surgical operation soft apparatus sheath of peritoneoscope pipe special-purpose member, earlier multichannel integrator apparatus supporting with it is mounted on skin surface before using, peritoneoscope scope, air induction conduit, operation technique bar enter in the body through multichannel integrator flexible channel (2).Laparoscopic surgical instruments can be moved in passage flexibly, and when operating theater instruments plug or operation are moved, guarantee the sealing of operation path, and applicable to the straight type of routine, flexure type operating theater instruments bar, flexible operation, easy to use, safe.
Above-mentioned example only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalent transformations that spirit is done according to the present invention or modification all should be encompassed within protection scope of the present invention.
