Abstract

The utility model relates to the electrode of the electric-cutting scope for bladder tumors, which is provided with an electrode body and a support rod. The electrode of the electric-cutting scope for the bladder tumors is characterized in that: the electrode head of the electrode body is in sickle-shaped or fishing-shaped, and the end of the electrode head and the support rod adopt the break-off type. The advantages of the electrode of the electric-cutting scope for the bladder tumors are that: under the direct vision of the electric-cutting scope, the sickle-shaped electrode head can be directly extended to the front part of the tumor bodies; the tumor bodies can be completely cut off; the residual dry tumor is harder and is somewhat fixed; the hemostasis is easy; the position from the tumor pedicle root to the muscular layer can be quickly excised; the visual field of the operation is clear, and the operation time is short.

Description

A kind of electrode of tumor of bladder resectoscope

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of electrode that tumor of bladder is carried out the resectoscope of electricity cutting through urethra.

Background technology

Per urethra tumor of bladder TURP method is a kind of Therapeutic Method commonly used in the shallow table tumor of bladder resection operation, at present common used resectoscope, the electrode body of its electrode is connected with support bar, electric current in the electrode body makes it insulation by insulant, and from appearance, electrode tip in the form of a ring, during work, as long as the electrode tip of energising is directly placed the borderline tumor place, by electrode tip tumor is carried out burning and cutting, the tumor body under the burning and cutting is again by the suction pipe sucking-off.It is little that this method has damage, recovers fast, repeatably advantage.The electrode of this structure, operator can only adopt the burning and cutting mode of " promoting forward " to the tumor body in operation process, so technical requirement is quite high, there have slightly to be improper, and vesical perforation easily takes place.Especially it is big to work as the tumor body, the patient that the base of a fruit is long, the impossible once resecting of its ring electrode can only begin to pass slowly burning and cutting downwards from tumor body tip, because of tumor body tip softness, easily drift, not only time-consuming but also feel is poor during excision, hemorrhage many, be difficult for hemostasis, surgical field of view is unclear, and vesical perforation easily takes place.

Summary of the invention

Technical barrier to be solved in the utility model is, overcome the deficiencies in the prior art, the electrode of the tumor of bladder resectoscope that a kind of root base of a fruit that angles tumor cuts tumor is provided, can makes electrode in operation, the burning and cutting mode of tumor be changed into present " draw cut type " by " the pushing away cut " in past and cut off mode.

Technical solution of the present utility model is, is provided with electrode body and support bar, it is characterized in that the electrode tip of electrode body is sickle shaped or angles shape, and is breakaway-element between the end of electrode tip and the support bar.

The utility model has the advantages that,, can under the direct-view of resectoscope, falculate electrode tip directly be reached tumor body the place ahead, pull back the cutting tumor pedicle, owing to adopt the action of cutting, can intactly cut down the tumor body in the operation because electrode tip is sickle shaped.And remaining tumor pedicle matter is hard and more fixing, easily further cutting and hemostasis.And can excise the tumor pedicle root soon to the flesh layer.Make surgical field of view clear.Operating time obviously shortens.

Specific embodiment

This utility model is provided with electrode body 1 and support bar 2, and the outside of electrode body 1 is provided with insulant 5, and the electrode tip 3 of electrode body 1 is sickle shaped or angles shape, is breakaway-element between the end of its electrode tip 3 and the support bar 2.

This utility model can be made with homemade mode.Be about to the center-right disconnection of the ring electrode of normal disjunctor from electrode tip 3, making becomes openly between itself and the support bar 2, again electrode tip 3 is curved sickle shaped or angles shape to get final product.During use, with sickle shaped or angle the electrode tip 3 of shape to extend tumor pedicle 4 root the place aheads, can cut tumor body 4 after the energising.In the operation, electrode cooperates resectoscope together to use, and can reach tumor body 4 the place aheads under the direct-view of resectoscope, angles tumor pedicle 4, cutting backward can be once or complete excision tumor body 4 for several times, can make wound face burn hemostasis voluntarily under electrode simultaneously, so operating time is short, go out insufficiency of blood, and relapse rate is low.

Claims

1, a kind of electrode of tumor of bladder resectoscope is provided with electrode body and support bar, it is characterized in that, the electrode tip of electrode body is sickle shaped or angles shape, and is breakaway-element between the end of electrode tip and the support bar.
