The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Shown in Fig. 8, the disposable operation retractor that makes to require mental skill of the present invention mainly comprises: lead and expand device 1, conductor 2 and be connected lock 3.
Wherein, lead expand device 1 conductor 2 mainly is installed when guiding and when operation, form operating theater instruments can by and mobile passage, therefore lead expansion device 1 and have a tube-in-tube structure, this tube-in-tube structure forms operation path for holding conductor 2 to be installed and to be invaded to organize.
Just lead and expand device 1 generally speaking, lead expansion device 1 and be formed with respectively operating side and bared end at the two ends of tube-in-tube structure, people's hand operated is convenient in operating side formation and other fixing devices are easy to fixing structure, and bared end is mainly used in coordinating the traction end of the conductor 2 exposed from this end to invade tissue, and removing the rear aligning lesions position of conductor 2.Therefore, in order to reduce the resistance of invading tissue and to reduce as far as possible the wound area, leading internal face and the outside wall surface of the tube-in-tube structure that expands device 1 shrinks to bared end gradually by operating side, wherein the design of the convergent of the internal face of tube-in-tube structure provides a space of being convenient to the operating theater instruments activity mainly for realizing, and the design of the convergent of outside wall surface is mainly in order to reduce the intrusion resistance.About leading the wall thickness expanded between device 1 tube-in-tube structure internal face and outside wall surface, can be both uniformity, also can adopt other design, this can be determined according to specific circumstances, and as a kind of preferred, wall thickness can be by operating side to bared end attenuation gradually.
Leading for the ease of the operation of hands the integral body that expands device 1 and conductor 2 compositions is invaded tissue, lead the operating side of expanding device 1 and be formed with two and the plural handle 4 of holding, hold handle 4 and can offer the enough contacts area of brothers, as a kind of preferred version, the number of holding handle 4 is 2 and is symmetrical arranged; Holding handle 4 is formed with for fixing projection 6 and gap slot 7.Projection 6 can realize in the fixing situation of time generation sidesway of snakelike retractor, in order to carry out the spacing sidesway that prevents in multiple directions as far as possible, the concrete form of projection 6 can be the burr with certain pattern, such as semicircle burr and the formed combination burr of both sides straight line burr.
Leading expansion device 1 at the larger activity space of operating side acquisition in order to make operating theater instruments, do not enlarge again to lead and expand the volume that device 1 is invaded tissue simultaneously, as a kind of preferred version, at the internal face that leads the tube-in-tube structure that expands device 1, be formed with outwardly open arc groove 8 in operating side.Further, the curved surface of arc groove 8 can be the part of a spheroid.Further, arc groove 8 is with to hold handle 4 numbers identical, hold handle 4 from above-mentioned arc groove 8 places to extending to form perpendicular to leading the axis direction that expands device 1 tube-in-tube structure.
Through our experiment, if finding to lead the convergent trend of the convergent design of expanding device 1 and conductor 2, we only from a direction, are shunk, when intrusion is organized, it is large that tissue is subject to a direction extruding degree, easily cause damage, and can not get desirable operation path, the outside wall surface of therefore as a kind of preferred version, leading the tube-in-tube structure that expands device 1 curved surface that the concentration ellipse curve of big or small gradual change forms of serving as reasons on the basis of convergent.On this basis, shown in Fig. 4, if hold the number of handle 4, be 2, hold the two ends that handle 4 and arc groove 8 can be formed at the elliptic curve major axis for two, and hold handle 4 and extend along the direction that is parallel to major axis, whole leading expanded the minor axis symmetry of device 1 about elliptic curve.
In addition, for convenient, observe, lead expansion device 1 and made and be provided with scale of depth by transparent material on tube-in-tube structure, such benefit is self-evident.
The main effect of conductor 2 is, forms the part of invading tissue, and exits by self after entering into assigned address, makes the tissue that leads expansion device 1 bared end avoid being extruded accumulation.Because the whole status requirement inserted of retractor is than darker several millimeters of the position of focus, the situation that can avoid tissue to be extruded like this.
With regard to it generally speaking conductor 2, is formed with and leads corresponding installation end and the traction end for from leading expansion device 1 bared end, stretching out and bared end can be sealed installed realized in expansion device 1 operating side.Traction end is formed with open-ended 5.
As a kind of preferred version, and lead that to expand device 1 similar, the outside wall surface of conductor 2 curved surface that the concentration ellipse curve of big or small gradual change forms of serving as reasons.
Connect to be used for and expand device 1 and conductor 2 and connect into as a wholely leading, for achieving this end, the installation end of conductor 2 is formed with the mounting structure 9 for fixed connection lock 3.
Particularly, mounting structure 9 is formed with inserting groove, this inserting groove one end sealing other end opens wide, connect lock 3 and can insert this inserting groove from a uncovered end, and can in this inserting groove, slide, an end that connects lock 3 insertions is provided with buckle structure 10, is positioned at a uncovered end and is formed with push button 11, and the inserting groove that need to illustrate should make buckle structure 10 expose and make it and lead gap slot 7 chuckings that expand device 1.
In order to realize self-locking, mounting structure 9 is provided with between 3 and withstands respectively them and buckle structure 10 is blocked lead the elastic component 12 that expands gap slot 7 on device 1 with being connected lock, inserting groove and be connected and lock 3 and all be formed with for withstanding the confined planes of elastic component 12.Elastic component 12 particularly can be selected helical spring, it should be noted that, inserting groove should be enclosed in elastic component 12 in cell body as far as possible.
Be arranged on and lead while expanding on device 1 at conductor 2, suitably promote push button 11, make to connect lock 3 compressing elastic components 12, now buckle structure 10 can dodge open lead expand device 1 hold handle 4, after aligning installs, unclamp push button 11, under the effect of elastic component 12, connecting lock 3 replys, buckle structure 10 just in time blocks the gap slot 7 of holding on handle 4, realizes that locking makes them form an integral body, after completing traction, promote push button 11 and get final product unlocked, exit to lead and expand device 1.
It should be noted that, gap slot has two kinds, and a kind of being used for locks, and a kind of is to coordinate for spacing for the downward projection with mounting structure 9 formation.
Need explanation the time, in view of the operation hygienic requirements, the present invention can be used as disposable surgical instrument, the analog structure that can reuse that certainly is subject to the present invention's enlightenment also should fall into protection scope of the present invention.
Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
