Preferably, wherein, described two long 18mm of horizontal concrete chute, its open top distance is 1mm, and bottom width is 3mm, the vertical chute length are 3mm, and open top distance is 3mm, bottom width 3.2mm, table in the vertical chute There is zigzag rubber groove (8) in face, and each serrated slot distance is 0.5mm, and sawtooth protrusion length is 0.2mm.

Preferably, wherein, the long 5mm of right angle knife, vertical section be long 3mm equilateral right angle, the right-angle side opening Air line distance is 3mm, and the hollow space (10) of long 4mm wide 0.7mm is equipped with the middle part of the right angle knife blade.

Preferably, wherein, described two transverse direction concave slide groove horizontal distances are 3mm, and the horizontal concrete chute recess is welded with The stainless steel rod (6) of one a diameter of 0.6mm.

The purpose of this utility model can also realize further by the processing and treating method of medical tarsus resectoscope, the party Method includes：

Preferably, wherein, stainless steel parts all select 304 stainless steels when the medical tarsus resectoscope makes, its Hardness is 50-70HRC.

Preferably, wherein, upper clip and lower clamping piece stainless steel parts will polish when the medical tarsus resectoscope makes Smooth in appearance is polishing to, without sharp edge, the upper lower clamping piece top opening 50mm is reclosed and examines its connection jail repeatedly for three times Soundness and elasticity.

The utility model includes at least following beneficial effect：Due to the horizontal concrete chute and the vertical chute knot of upper clip angle coupling head Structure, therefore the height of right angle knife can be adjusted；

Due to there is fixed strip method on horizontal concrete chute, right angle knife can be fixed, ensures that right angle knife will not teetertotter；

Since the upper clip and the lower clamping piece form a V-arrangement tarsus folder, its opening portion can clamp eyelid And draw upset eyelid；

Due to handle, the handle end is integrally formed middle part and is separately divided into upper clip handle and lower clamping piece handle, and divides The through hole of an a diameter of 2mm, one a diameter of 1.9mm of the through hole are not made at middle part, length is the bolt of 15mm under The one end in intermediate plate hole is pierced into, and is twisted with the fingers tightly in the inner side of lower clamping piece with nut, then bolt is pierced by from the hole of upper clip, in upper clip Outside twist with the fingers tight nut, the handle be bar shaped Anti-slip handle, its middle part outer surface of outer cover setting bar shaped layer of silica gel, therefore can Prevent from producing dislocation during use；

Since the vertical chute inner surface has zigzag rubber groove (8), each serrated slot distance is 0.5mm, and sawtooth is convex It is 0.2mm to go out length, therefore can block translot both ends, ensures that translot will not be slided up and down arbitrarily；

Due to the long 5mm of right angle knife, vertical section is the equilateral right angle of long 3mm, and the right-angle side opening air line distance is 3mm, the right angle knife blade middle part is equipped with the hollow space (10) of long 4mm wide 0.7mm, therefore it is a wedge shape to cut off effect Strip, but eyelid will not be cut through.

Since described two horizontal concave slide groove horizontal distances are 3mm, it is a diameter of that the horizontal concrete chute recess is welded with one The stainless steel rods of 0.6mm (6), thus can be right angle knife be stuck on horizontal concrete chute and can slide reach excision tarsus effect；

Since the medical tarsus resectoscope upper clip and lower clamping piece stainless steel parts want polishing grinding not have to smooth in appearance There is sharp edge, therefore can guarantee that the security of operation, prevent the generation of malpractice；

It is placed on after being completed due to the medical tarsus resectoscope in the boiling water of submergence height 40mm and boils 30 minutes with inspection Its corrosion resistance is tested, is put into 500 DEG C of high temperature sterilization case and kills virus after the assay was approved, therefore wound is caused after can preventing operation Infection.

The further advantage, target and feature of the utility model embody part by following explanation, and part will also pass through Research and practice to the utility model and be understood by the person skilled in the art.
