Description

Medical perpendicular type Wicresoft incision knife

Technical field

This utility model relates to medical instruments, is specifically related to a kind of perpendicular type incision knife that cuts urethral stricture scar tissue for Urology Surgery endoscope micro-wound.

Background technology

Urethral stricture is the clinical common frdquently encountered disease of Urology Surgery, overwhelming majority patient's the cause of disease is a large amount of fibrous scar tissue hypertrophy after injury of urethra, thereby cause urethra inner chamber narrow, make patient deeply be subject to dysuria, the misery of the malaise symptoms such as urinary tract infection, hematuria, frequent micturition repeatedly, even can cause bladder function to lose the severe complications such as compensatory, upper urinary tract hydrops, chronic renal failure.

At present clinically for this type of patient, mainly use endoscope micro-wound treatment technology, in concrete operation process, conventionally use linear type incision knife that scar tissue is cut.The drawback of above-mentioned linear type incision knife is, linear type incision knife only has place's upper knife edge and direction to fix, blade easily weares and teares, cause once operation often will change Shuo Ba Wicresoft incision knife, greatly increased medical expense consumption, and surgical doctor is not easy to hold incision strength and the direction of linear type incision knife, thereby cause cicatrix to cut Efficiency Decreasing, easily causing incision thoroughly not cause postoperative urethral stricture recurs repeatedly, or cause and cut dark and cause injury of urethra, even cause the severe complications such as massive hemorrhage, urine fistula.

Summary of the invention

For overcoming above-mentioned deficiency, this utility model provides a kind of medical perpendicular type Wicresoft incision knife, cutter head and the handle of a knife connecting portion of this perpendicular type Wicresoft incision knife are rectangular, and cutter head has three place's blades, be respectively front cutting edge, upper knife edge and rear knife edge, not only can distinguish forward, on, rear three directions are cut urethral scar tissue, and surgical doctor pushes away before can easily using, tractive, on lift, the operational motions such as rotation, incision direction and angle that so can remarkable open urethral stricture endoscope micro-wound, and surgical doctor can very easily be controlled incision strength, improved greatly the incision efficiency of urethral stricture scar tissue, for surgical effect and prognosis provide good guarantee, can also greatly reduce medical expense consumption simultaneously, can Reusability after medical perpendicular type Wicresoft incision knife ethane via epoxyethane sterilization treatment.

This utility model solves the technical scheme that its technical problem adopts:

This utility model provides a kind of medical perpendicular type Wicresoft incision knife, cutter head has three place's blades, cutter head and handle of a knife connecting portion are rectangular, there is the cylindric retainer ring of the hollow that is parallel to cutter head handle of a knife front portion, the special-purpose endoscope of tolerable Urology Surgery Minimally Invasive Surgery walk by and the fixing position of handle of a knife, cutter tail can connect Urology Surgery Minimally Invasive Surgery special equipment operating grip.

Medical perpendicular type described in the utility model Wicresoft incision knife, three place's blades of cutter head are respectively the upper knife edge of circular arc, perpendicular to front cutting edge and the rear knife edge of handle of a knife.

This utility model entire body is made by identical material metal, cutter tail can insert Urology Surgery Minimally Invasive Surgery special equipment operating grip, the hollow cylindrical retainer ring through handle of a knife front portion by the special-purpose endoscope of Urology Surgery Minimally Invasive Surgery simultaneously, the spacing of adjusting incision knife cutter head and endoscope head is to fixing incision knife after correct position, by control operation hands handle, can cut finding scar tissue fully to expand urethra inner chamber according to needed direction and angle, before using, promote to do to cut the cicatrix of cutter head proximal part, the cicatrix of using tractive action to cut cutter head distal end, in use, lift and push pull maneuver incision cutter head veutro cicatrix, use rotation push pull maneuver to cut cutter head dorsal part cicatrix, so can reach " without dead angle " and cut narrow scar tissue, fully guaranteed the effect of urethral stricture minimal invasive operation, reduce urethral stricture Postoperative recurrent rate, and surgical doctor can be adjusted incision strength easily in whole operation process, avoid to greatest extent hemorrhage, the complication such as urine fistula, can Reusability after medical perpendicular type Wicresoft incision knife ethane via epoxyethane sterilization treatment.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

In figure 1, perpendicular type connecting portion, 2, cutter head, 3, front cutting edge, 4, upper knife edge, 5, rear knife edge, 6, handle of a knife, 7, retainer ring, 8, cutter tail.

The specific embodiment

Entire body is made the medical perpendicular type of this utility model Wicresoft incision knife by identical material metal, total length 27cm, the long 3mm of cutter head 2, rectangular with the connecting portion 1 of handle of a knife 6, cutter head 2 has three place's blades, be respectively the upper knife edge 4 of circular arc, front cutting edge 3 and rear knife edge 5 perpendicular to handle of a knife, handle of a knife 6 diameter 2mm, there is the cylindric retainer ring 7 of the hollow that is parallel to cutter head 2 its front portion, retainer ring 7 diameter of section 3.5mm, long 20mm, the special-purpose endoscope of tolerable Urology Surgery Minimally Invasive Surgery walk by and the fixing position of handle of a knife 6, cutter tail 8 can connect Urology Surgery Minimally Invasive Surgery special equipment operating grip.In concrete operation implementation process, first cutter tail 8 is inserted to Urology Surgery Minimally Invasive Surgery special equipment operating grip, the hollow cylindrical retainer ring 7 through handle of a knife 6 front portions by the special-purpose endoscope of Urology Surgery Minimally Invasive Surgery simultaneously, the spacing of adjusting incision knife cutter head 2 and endoscope head is to fixing incision knife after correct position, then aforesaid operations apparatus is inserted to patient's urethra inner chamber at endoscope's direct-view retrograde, find narrow scar tissue, by control operation hands handle, can cut finding scar tissue fully to expand urethra inner chamber according to needed direction and angle, before using, promote to do to cut the cicatrix of cutter head 2 proximal parts, the cicatrix of using tractive action to cut cutter head 2 distal ends, in use, lift and push pull maneuver incision cutter head 2 veutro cicatrixs, use rotation push pull maneuver to cut cutter head 2 dorsal part cicatrixs, so can reach " without dead angle " and cut narrow scar tissue, fully guaranteed the effect of urethral stricture minimal invasive operation, reduce urethral stricture Postoperative recurrent rate, and surgical doctor can be adjusted incision strength easily in operation implementation process, avoid to greatest extent hemorrhage, the complication such as urine fistula, can Reusability after medical perpendicular type Wicresoft incision knife ethane via epoxyethane sterilization treatment.
