Abstract
The utility model discloses a cold knife internal incision device for urethrostenosis surgery, comprising a main body of the cold knife internal incision device. The cold knife internal incision device mian body is provided with a knife edge section used for cutting; a through hole is arranged on the front end of the knife edge section. The utility model can be used under the conditions when the endoscope can not be used; by putting a thread through the hole on the front end of the cold knife edge, operation can be carried out under the guiding and pulling effect of the guiding thread. As the cold knife internal incision device is used independently without the endoscope, the clinical indications of the urethra internal incision is extended, the damages to the normal tissue is avoided and no pseudo tract is formed in the operation, thereby ensuring successful operation and reducing the suffering and medical expenditure of the patient.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to cutter in a kind of cryoprobe that uses in the urethral stricture operation.
Background technology
In the operation of treatment urethral stricture, need to use cutter in the cryoprobe at present.During operation, cutter in the cryoprobe must be installed in the endoscope, the doctor uses cutter in the cryoprobe by the observation of endoscope.Because the disease of a lot of patient's urethral strictures, the narrow section of urethra that occurs near the urethral orifice anterior urethra or patient is longer, in this case, because endoscope can not stretch in the urethra, and causes the interior cutting operation of urethra normally to carry out.If implement the way of cutting by force, tend to normal structure damage and cut out via, cause operative failure and must carry out the open surgery treatment, this has just increased the difficulty of operation and patient's misery, has prolonged patient's the post-operative recovery time simultaneously.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model provides a kind of independent used follow-on interior cutter of cryoprobe that is used for the urethral stricture operation.
For achieving the above object, this utility model is a kind of to be used for cutter in the cryoprobe of urethral stricture operation, comprises cutter body in the cryoprobe, and the cutter body has incisory blade section in this cryoprobe, is provided with through hole at the leading section of described blade section.
Further, the cross section of described through hole is circular, and the diameter of section of this through hole is 0.5-1.5mm.
Compared with prior art, this utility model is used for the interior cutter of cryoprobe of urethral stricture operation, under the situation that can't use endoscope, silk thread is passed the through hole that cryoprobe blade front end is provided with, under seal wire guiding and traction, carry out interior cutting operation, realized breaking away under the situation of endoscope and used cutter in the cryoprobe separately, enlarged the indication of internal urethrotomy, avoided in the operation damage normal structure or form via, thereby the success that has guaranteed operation is carried out, and has reduced patient's misery and medical expense.
Description of drawings
Fig. 1 is used for the front view of cutter in the cryoprobe of urethral stricture operation for utility model;
Fig. 2 is used for the vertical view of cutter in the cryoprobe of urethral stricture operation for utility model;
Fig. 3 is the partial enlarged drawing of knife edge part among Fig. 2.
The specific embodiment
Utility model is used for that cutter is further described in the cryoprobe of urethral stricture operation below in conjunction with accompanying drawing:
Among Fig. 1-3, cutter comprises that knife bar 1, cutter tail 2 and incisory blade section 3 form in the cryoprobe, has the matching used installation sleeve 4 with endoscope on knife bar 1, has through hole 5 at the leading section of blade section 3, and through hole 5 be a circle, and its diameter is 0.5mm-1.5mm.
In the time can't using endoscope in the operation, utilize from the retrograde silk thread that passes of bladder to be fixed on the through hole 5 of blade section 3, under the guiding and traction of seal wire, utilize the interior cutter of cryoprobe directly to carry out interior cutting operation.Like this, just can avoid damaging normal structure or form via, making operation be able to success and carrying out, avoid adopting open surgery, alleviated the patient suffering and shortened post-operative recovery time of patient.
Equally, the shape of through hole 5 also can be ellipse, and its size can suitably be adjusted as required.
