Further, the rear end of the transfusing chamber is respectively connected with rubber tubing.
Compared with prior art, the utility model has the beneficial effects that the utility model the inside of knife handle have two it is defeated
Sap cavity, when scalpel cuts eyes chalazion, medical fluid feeds out of elbow input eyes and synchronizes, it can be achieved that infusing and inhaling,
Affected part pressure balance is kept, two-tube drain is smooth, improves the safety and success rate of operation；In addition, using two-tube infusion, it can root
Single tube or two-tube carry out drain are used according to situation, realizes the reasonable employment of medical fluid, improve procedure efficiency and shortens operating time, separately
Instrument and equipment needed for also saving operation outside, operation is improved in the reparation that can meet postoperative period, and can save operative space.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of ophthalmology chalazion scalpel.
Fig. 2 is the schematic diagram of internal structure of ophthalmology chalazion scalpel.
Fig. 3 is the structural schematic diagram of blade movable chamber in ophthalmology chalazion scalpel.
Fig. 4 is the side view of ophthalmology chalazion scalpel.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Fig. 1-4, a kind of ophthalmology chalazion scalpel, including knife handle 1 and blade 3 are please referred to, 1 material of knife handle is transparent
Acrylic material is equipped with scale 11 on knife handle 1 along its length, is equipped with the arc groove 12 for facilitating gripping in the middle part of knife handle 1；
The inner lower of the knife handle 1 offers blade movable chamber 2, is equipped with screw rod 21 in blade movable chamber 2, before screw rod 21
It holds and is rotatablely connected with the inner wall of blade movable chamber 2, the rear end of screw rod 21 and the inner wall of movable chamber 2 are rotatablely connected and are pierced by blade and live
Dynamic chamber 2, the rear end of screw rod 21 are fixedly connected with knob 22, and anti-skid chequer, 22 front end of knob and 1 rear end of knife handle are offered on knob 22
Between screw rod 21 on be threaded with fixture nut 23；
The blade 3 is located inside blade movable chamber 2, and 2 front end of blade movable chamber offers blade outlet 31, and blade 3 is living
Dynamic setting is in blade outlet 31, and the rear end of blade 3 is fixedly connected by L-type connecting rod 32 with feed screw nut 33, feed screw nut
33 are threaded on screw rod 21；It is the disengaging of adjustable blade 3 by rotation knob 22, behind the position for regulating blade 3,
