Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of visual biliary tract stone extraction device.
Background technology
Doctor is when performing the operation to Biliary Calculi patient, and owing to there being blind area, doctor can only rely on feel blindly to get stone, and efficiency is not high, is difficult for exhausting calculus, and may occur that binding clip damages bile duct inwall and causes the severe complications such as hemorrhage, perforation.
Summary of the invention
The purpose of this utility model is, a kind of visual biliary tract stone extraction device is provided, and solves existing Lithotomy forceps and has blind area, easily causes residual stones and the impaired problem of bile duct inwall.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of visual biliary tract stone extraction device, comprise Lithotomy forceps, photographic head, optic fibre wire, additional light source, hollow assembly and display, described Lithotomy forceps comprises the claw beam of two hinge connection, and the first end of two claw beams is respectively equipped with finger ring cover, and the second end is respectively equipped with binding clip; A described claw beam is provided with two or more hollow assemblies therein, and described hollow assembly has the through-hole structure that can make optic fibre wire pass; Described optic fibre wire can be fixed on described claw beam with removably by the through-hole structure of described hollow assembly; Described optic fibre wire is connected with photographic head near one end of binding clip, and the optic fibre wire other end extends to finger ring cover rear end always and stretches out finger ring cover and is connected with display; Clamp headend at described Lithotomy forceps arranges additional light source, and this additional light source is connected with outside power supply by connecting line.
Preferably, described additional light source is compact LED lamp.
Preferably, described photographic head is fiber lens.
Preferably, described hollow assembly be arranged on described claw beam outer peripheral sidewall, along claw beam axial direction, arrange point-blank.
Preferably, the through-hole structure of described hollow assembly is the little pore structure in large middle part, two ends.
Preferably, the through-hole structure of described hollow assembly is inner arranges in order to block the buckle of optic fibre wire.
Preferably, the connecting line of described additional light source is fixed on described claw beam by the through-hole structure of described hollow assembly.
Compared with prior art, the beneficial effects of the utility model are: by a plurality of hollow assemblies are set on the claw beam of Lithotomy forceps, this hollow assembly has through-hole structure, thereby optic fibre wire can be fixed on claw beam with removably by through-hole structure.Due to the Lithotomy forceps operation that needs to carry out disinfection in each use procedure, so the photographic head of optic fibre wire and connection is fixed on and on claw beam, just has more Clinical practicability with removably.Visual biliary tract stone extraction device of the present utility model, optic fibre wire is easy to be fixed to claw beam and conveniently from claw beam, disassembles, and has more operability in practical clinical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the visual biliary tract stone extraction device of this utility model embodiment;
Fig. 2 is the schematic cross-section of hollow assembly after Lithotomy forceps fixed fiber wire in this utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described.
As shown in Figure 1, visual biliary tract stone extraction device comprises Lithotomy forceps 1, photographic head 2, optic fibre wire 3, additional light source 4, hollow assembly 5 and display 6.Wherein, Lithotomy forceps 1 comprises the claw beam 11 of two hinge connection, and the first end of claw beam is that finger ring cover the 12, second end is binding clip 13.On one of them claw beam 11 of Lithotomy forceps, four hollow assemblies 5 are set, each hollow assembly 5 all has the through-hole structure that optic fibre wire 3 is passed.In use procedure, optic fibre wire 3 is passed to the through-hole structure of the hollow assembly 5 on claw beam successively along one end of claw beam 11, thereby be fixed on claw beam; Then by optic fibre wire 3, the one end near binding clip is connected with photographic head 2, and photographic head is fixed on to clamp headend, and the other end of optic fibre wire 3 extends to finger ring always and overlaps 12 rear ends and stretch out finger ring cover and be connected with display 6.Additional light source 4 is arranged on binding clip 13 ends, by connecting line, is connected with external power source, and this connecting line can be arranged in claw beam, or the through-hole structure by hollow assembly 5 is fixed on claw beam and is also fine.In clinical use, additional light source 4 is externally luminous after Power supply, photographic head 2 carries out image acquisition, and the image information of collection is transferred to display 6 by optic fibre wire 3 carries out image demonstration, thereby the region, blind area in biliary tract stone extraction process can be observed.
In described biliary tract stone extraction device, because optic fibre wire is very thin, therefore the through-hole structure of described hollow assembly need to be set to narrow and small hole, to prevent that optic fibre wire from coming off from claw beam again after fixing.For optic fibre wire is easy to, penetrate narrow and small through-hole structure, can be set to the little pore structure in large middle part, two ends by through-hole structure.That is to say, the porch, two ends of through-hole structure is set to relatively large aperture, and the middle part of through-hole structure can be set to narrow and small hole.Or also buckle structure can be set in through-hole structure, thereby be fixed in order to block the optic fibre wire penetrating.
Described hollow assembly 5 can be arranged in the outer peripheral sidewall of any one claw beam of Lithotomy forceps 1, the quantity of hollow assembly be 2 or more than.The preferred set-up mode of this hollow assembly is: several hollow assemblies are arranged point-blank along the axial direction of described claw beam.When hollow component count is 2, two hollow assemblies need to be separately positioned on two ends of claw beam, so that optic fibre wire is fixed on claw beam better.When hollow component count is when more than 2, preferred version is that hollow assembly is arranged in the outer peripheral sidewall of claw beam with proportional spacing, so that more stable being fixed on claw beam of optic fibre wire.
As preferred embodiment a kind of, described hollow assembly 5 is set to form of grooves, for example, can be set to semi-circular recesses, and described optic fibre wire is positioned in groove, and groove upper end is fixed by cross-bridges.Referring to Fig. 2, this figure has shown the schematic cross-section of described hollow assembly after Lithotomy forceps fixed fiber wire.Hollow assembly 5 includes groove 51 and cross-bridges 52, and optic fibre wire 3 is positioned over the interior position of groove of groove 51.The advantage of the hollow assembly of this structure is: in use procedure, can avoid some to involve, better effects if.
Described additional light source 4 can be arranged on the clamp headend of arbitrary claw beam, luminous by external power source in use procedure.The photographic head that clamp headend is connected with optic fibre wire is preferably fiber lens, because light camera lens is very tiny, and can be crooked, image quality is also very good, is more suitable for using in clinical manipulation.The in the situation that of additional light source luminescent, fiber lens gathers after the image information of clamp headend region, by optic fibre wire, image transmission to the display of claw beam outer end is carried out to image demonstration, doctor can get more accurately stone by the image information on display and operate.
Above are only preferred embodiment of the present utility model, this utility model is not limited in the content of embodiment.To those skilled in the art, within the scope of the technical solution of the utility model, can have various variations and change, any variation and the change done, all within this utility model protection domain.
