Description

A kind of note suction handle needle

Technical field

The utility model is related to a kind of medical apparatus for treating cataract more particularly to a kind of note to inhale handle needle.

Background technology

There is a step in phacoemulsification surgical procedure at present：Crystal water separation, water stratification.For above-mentioned step Rapid Normal practice is：An oblique curved needle head is connected with the syringe for loading onto water, underwent operative notch is inserted directly under anterior lens capsule Injection, makes crystal be detached with pouch, is inserted under lens cortex and injects, so that lens cortex is detached with core, that is, realize crystal water Separation, water stratification.The purpose of the step is to keep lens cortex and core free, is detached with pouch.The step success or not is to follow-up Phacoemulsification step has important booster action.

Above-mentioned way is limited in that：Doctor needs the dynamics for rule of thumb judging injection, if dynamics is excessive, be easy Crystal pouch is caused to rupture, therefore modus operandi may change, influence postoperative effect；And dynamics is too small cannot good moisture From, water stratification, operation subsequent step difficulty and increased risk when crystal is had children outside the state plan and emulsified.

Utility model content

The main purpose of the utility model is to provide a kind of note inhale handle needle, the note inhale handle needle can be perfused simultaneously and Suction, so can control dynamics well, reach preferably surgical effect.

To achieve the above objectives, the technical solution adopted in the utility model is：A kind of note suction handle needle, which is characterized in that Including handle and the syringe needle for being placed coaxially on handle one end, the handle is tubular structure, and the syringe needle includes outer barrel and same Inner cylinder in outer barrel is set to axis, and the cavity between the outer barrel and inner cylinder forms perfusion channel, is formed inside the inner cylinder Suction channel is provided with perfusing hole, in the one end of the inner cylinder far from handle in the both sides of the one end of the outer barrel far from handle It is provided with pump orifice.

Preferably, the suction tube for being respectively arranged with the intrusion pipe being connect with outer barrel in the handle and being connect with inner cylinder, it is described Intrusion pipe is connected to the perfusion hose of ultrasonic emulsifier, and the suction tube is connected to the suction hose of ultrasonic emulsifier.

Preferably, the syringe needle has certain bending angle.

Preferably, the bending angle is 135 °.

Compared with prior art, which has the advantages that：

The note inhales handle needle and can be achieved at the same time perfusion and suction, and then can be more prone to control the pressure in pouch, It avoids dynamics excessive or too small, improves the safety of operation.

Fig. 2 is the connection figure of a preferred embodiment and ultrasonic emulsifier according to the present utility model

Specific implementation mode

It is described below for disclosing the utility model so that those skilled in the art can realize the utility model.It retouches below Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.

As shown in Figs. 1-2, which inhales handle needle and includes handle 2 and be placed coaxially on the syringe needle 1 of 2 one end of handle, described Handle 2 is tubular structure, and the syringe needle 1 includes outer barrel 11 and the inner cylinder 12 being placed coaxially in outer barrel 11, the outer barrel 11 Form perfusion channel between inner cylinder 12,12 inside of the inner cylinder forms suction channel, the outer barrel 11 far from handle 2 one The both sides at end are provided with perfusing hole 13, and the one end of the inner cylinder 12 far from handle 2 is provided with pump orifice 14, the perfusing hole 13 To pouch water filling, the pump orifice 14 to by pouch water and broken lens nucleus be sucked out.

The intrusion pipe 21 being connect with outer barrel 11 and the suction tube being connect with inner cylinder 12 22, institute are respectively arranged in handle 2 It states intrusion pipe 21 to be connected to the perfusion hose 3 of ultrasonic emulsifier, the suction tube 22 and the suction hose 4 of ultrasonic emulsifier connect It is logical, and then the perfusion and suction that note inhales handle needle can be controlled by ultrasonic emulsifier.Wherein, ultrasonic emulsifier uses existing skill Art, and will not be described here in detail.

It is inserted into pouch in order to facilitate syringe needle simultaneously, syringe needle 1 can be with the certain angle of bending, preferably 135 °.

When in use, syringe needle 1 is inserted into insertion anterior lens capsule by hand-held handle 2, then by controlling ultrasonic emulsifier I/A function programs realize perfusion and suction.

Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model the utility model also have respectively Kind changes and improvements, these changes and improvements are both fallen in claimed the scope of the utility model.The requires of the utility model Protection domain defined by appended claims and its equivalent.
