Abstract
The invention discloses a loop ligature device for a bladder tumor, which comprises a loop ligature device body and a loop ligature metal coil, wherein the loop ligature device body takes the shape of a hollow cavity, one end of the loop ligature device body is connected with a handle, on end of the handle is connected with a binding post, the binding post is located in the hollow cavity in the loop ligature device body, a flexible insulation sleeve is connected onto the binding post, the loop ligature metal coil is led in from an on-point of the binding post and led out from an off-point of the binding post and is simultaneously sleeved in the flexible insulation sleeve and a lower flexible insulation sleeve, the on-point and the off-point of the binding post are respectively connected with electrodes, and the electrodes are connected with an external power source. The loop ligature device for the bladder tumor is simple in structure and convenient in operation, the field is clear in the operation process, and the directivity and the controllability of the operation can help to completely remove the tumor better and shorten the operation time.
Description
Technical field
The present invention relates to field of medical, refer more particularly to a kind of looping and binding device for tumor of bladder.
Background technology
Underwent transurethral resection of bladder tumor is the shallow table tumor of bladder most common therapeutic method of excision, and it is little to have a damage, recovers fast, and advantage has repeatably become the goldstandard of non-flesh layer invasive bladder cancer treatment.But traditional resectoscope has the following disadvantages during greater than the big pedunculated tumor of 3cm at excision tumor of bladder, particularly diameter of tumor: 1, tumor body tip softness, drift, and fixing, lack good tactile feedback and comparatively time-consuming during excision; 2, tumor of bladder blood is for all at root, root not before the excision first tumor resection surface cause easily hemorrhage, the visual field is unclear, and then may cause vesical perforation; 3, tumor piecemeal cutting has increased the potential risk that tumor cell comes off and plants; 4, some privileged sites tumor as the antetheca tumor, needs the assistant to continue to press suprapubic region to expose tumor, and the bubble that produces in the TURP process is easy perturbation operation also, to operator's experience and skill proposition higher requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of simple in structure, the operating process visual field clear, directivity and the controllability of operation can better complete tumor resections and shorten operating time, the practical looping and binding device that is used for tumor of bladder.
The present invention realizes in the following way:
A kind of looping and binding device for tumor of bladder is characterized in that: comprise looping and binding device body 1, cover bundle wire coil 2, looping and binding device body 1 is cavity-like, and the one end is connected with handle 3; Be connected with binding post 4 on one end of described handle 3; Described binding post 4 is positioned at the cavity of looping and binding device body 1; Be connected with flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6 on the described binding post 4; The described other end of going up flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6 all is positioned at the cavity of looping and binding device body 1; Described cover is pricked wire coil 2 from the access point access of binding post 4, and picks out from picking out a little of binding post 4, is sheathed on simultaneously in flexible insulation sleeve pipe 5 and the following flexible insulation sleeve pipe 6; The access point of described binding post 4 is connected with electrode 7 respectively with picking out a little; Described electrode 7 is connected with external power supply.
Beneficial effect of the present invention is: simple in structure, easy to operate, can under looking at straight, reach below the tumor root, ligation the base of a fruit fixes tumor pedicle, is convenient to complete thorough tumor resection, surgical field of view is clear, and operating time obviously shortens, and reduces the probability of vesical perforation; Reduce the tumor cell plantation risk that comes off simultaneously; Fixedly also be convenient to separating of non-flesh layer wellability tumor and substrate after the tumor the base of a fruit, make operation simple and easy, be convenient to accurate tumor resection and reach the flesh layer; Lower urinary tract disease diagnosis and therapeutic quality are obviously improved.

The specific embodiment
Now by reference to the accompanying drawings, the specific embodiment of the invention is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of looping and binding device for tumor of bladder comprises looping and binding device body 1, cover bundle wire coil 2, and looping and binding device body 1 is cavity-like, and the one end is connected with handle 3; Be connected with binding post 4 on one end of handle 3; Binding post 4 is positioned at the cavity of looping and binding device body 1; Be connected with flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6 on the binding post 4; The other end of last flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6 all is positioned at the cavity of looping and binding device body 1; Cover is pricked wire coil 2 from the access point access of binding post 4, and picks out from picking out a little of binding post 4, is sheathed on simultaneously in flexible insulation sleeve pipe 5 and the following flexible insulation sleeve pipe 6; The access point of binding post 4 is connected with electrode 7 respectively with picking out a little; Electrode 7 is connected with external power supply.
Looping and binding device body 1 diameter of the present invention is adjustable, and adjustable size is F5, F6, and F7, length can be stretched, and can also be used for ureter under special circumstances, is applied to the tumor of ureter TURP in the solitary kidney.
Cover of the present invention is pricked wire coil 2 diameter can be according to the tumor size variation, and the about 3-5cm of diameter can be changed to the wire net shape when special.
The flexible insulation sleeve pipe 5 of going up of the present invention adopts the insulation materials to make with following flexible insulation sleeve pipe 6, and safety prevents short circuit.
As shown in Figure 3, when the looping and binding device of using the tumor of bladder of the technical program carries out the diagnosis of lower urinary tract illness or treatment, earlier looping and binding device body 1 is inserted bladder through the resectoscope handle hole, under the bright field state, seek tumor and the left end of looping and binding device body 1 is aimed at tumor of bladder the base of a fruit, when operation resectoscope handle and handle 3 move forward, cover is pricked wire coil 2 and will be stretched out from the left end of last flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6, and under the elastic dilatation effect of last flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6 formation lasso automatically, the lasso diameter can be pricked wire coil 2 according to cover and be stretched out the length adjustment, to overlap loop diameter be adjusted to tumor size coupling after, the direct-view of resectoscope sight glass is enclosed within tumor the base of a fruit with lasso down, move gradually and tighten up looping and binding device body 1, lasso diminishes until the ligation tumor the base of a fruit that is locked thereupon gradually, electrode 7 external power supplys, the control on and off switch cooperates the resectoscope handle mobile backward, completely solidifies cutting and removes the tumor body.In completely cutting off down of last flexible insulation sleeve pipe 5 and following flexible insulation sleeve pipe 6, cover is pricked wire coil 2 and external power supply forms complete cutting current loop.After the complete excision of tumor, also can by cover prick wire coil 2 adjustment collar diameters prick the tumor cover fixing and through the resectoscope sheath with the complete taking-up of tumor.Bigger as the tumor of bladder diameter, can the cover cutting except tumor root, blocking-up tumor blood for after again with the cutting of tumor piecemeal cover except taking out, effectively improve the visual field and reduce the tumor cell plantation that comes off.
