Definitions
- the present invention relates to a cannula used in ophthalmic surgery.
- FIG. 3 is a diagram showing the state of ophthalmic surgery.
- the conventional cannula 110 has a configuration in which a metallic pipe 111 is fitted into a base 112 made of a hard resin.
- the base 112 has a substantially cylindrical shape and is provided with a groove 112a along the circumference in the vicinity of an intermediate position on the side surface so that the cannula 110 can be grasped with tweezers.
- the base 112 comes into contact with the eyeball A to function as a stopper and is held in the pierced state.
- Various surgical instruments 20 and optical equipment for monitoring are inserted into the eyeball through the cannula 110. Therefore, during the operation, the cannula 110 may be pierced by three or four into one eyeball.
- FIG. 4 is a view showing a state where a conventional cannula is pierced through an eyeball.
- the angle ⁇ between the axial direction b of the cannula 110 and the normal direction a of the eyeball A may be about 30 ° to 45 °. is there.
- the base 112 has a substantially cylindrical shape and is made of a hard resin
- the surgical instrument 20 when the surgical instrument 20 is moved to change the angle ⁇ of the cannula 110, the corner 112b of the base 112 contacts the eyeball A. Therefore, the piercing portion of the pipe 111 becomes shallow, and a problem that the cannula 110 comes out of the eyeball A during the operation may occur.
- a force acts in a direction in which the joint portion 112c of the pipe 111 and the base 112 opens with the corner portion 112b as a fulcrum, so that a problem may occur that the pipe 111 is easily detached from the base 112. .
- the contact point between the eyeball A and the base 112 is a point contact at the corner 112b, the base 112 can roll right and left on the eyeball A. Therefore, when the base 112 is made of a hard resin, there is a problem that the eyeball A may be damaged.
- the present invention suppresses the cannula from being easily removed from the eyeball when a surgical instrument or the like is moved.
- An object of the present invention is to provide a cannula that can prevent the pipe from coming off the base.
- a cannula according to the present invention is a cannula that is used by being pierced into an eyeball in ophthalmic surgery, and is a metal pipe that is pierced through an eyeball and a base made of a flexible material that is joined to one end of the pipe It shall comprise.
- the center part of the end surface of the base on the eyeball side is depressed, or if the base contacts the eyeball, the contact portion of the base is deformed.
- the base since the base has flexibility, there is an effect that the eyeball is not damaged even if a surgical instrument or the like is moved, and that the pipe is not easily detached from the base. Further, since the base is deformed, the depth of the pipe pierced into the eyeball is hardly changed, and an effect of suppressing the cannula from being easily pulled out can be obtained.
- FIG. 1 is a plan view of a cannula of the present invention. It is a figure which shows the state which pierced and moved the cannula of this invention, Comprising: (a) is the state moved small, (b) is the state moved large. It is a figure which shows the condition of ophthalmic surgery. It is a figure which shows the state which pierced the eyeball with the conventional cannula.
- FIG. 1 is a plan view of the cannula of the present invention.
- the cannula 10 of the present invention includes a metal pipe 11 and a substantially cylindrical base 12.
- the pipe 11 is attached by inserting one end side through the center position of the cylindrical base 12.
- the base 12 functions as a stopper when the pipe 11 is inserted into the eyeball A.
- grooves 12a are formed along the circumference at the side surface positions of the columnar shape. This groove 12a is used to hold the cannula with tweezers. Further, the end surface of the base 12 on the side in contact with the eyeball A has a shape having a recess 12d near the center of the circle. That is, the cross section obtained by cutting the base 12 in the vertical direction has a concave shape on the eyeball side. Then, since the curved surface of the eyeball A matches the recess 12d, the eyeball A and the base 12 can be in close contact with each other as shown in FIG.
- the base 12 is assumed to have flexibility (elasticity), specifically, a material softer than the eyeball A may be used. If the base 12 is flexible, the surgical instrument can be moved while the eyeball A and the base 12 are in close contact as shown in FIG.
- FIG. 2 is a diagram showing a state where the cannula of the present invention is pierced and moved through the eyeball, where (a) is a small movement state and (b) is a large movement state.
- the state of the small movement in FIG. 2A is a state in which the surgical instrument 20 is moved while the eyeball A and the base 12 are in close contact as shown in FIG. 1, and the cannula 10 is moved accordingly.
- the greatly moved state means that as a result of moving the surgical instrument 20, the angle ⁇ between the normal direction a of the eyeball A and the axial direction b of the cannula 10 is about 30 ° to 45 °.
- the base 12 Since the base 12 has flexibility, particularly when the base 12 is softer than the eyeball A, when the cannula 10 is pressed against the eyeball A, the base 12 is moved to the eyeball A as shown in FIGS. Deforms to match the shape of At this time, if the depression 12d is provided in the central portion of the eyeball side end surface of the base 12, the flexibility is further increased, and therefore, the deformation becomes easier.
- the cannula of the present invention can be manufactured by the same operation as before, so that there is no disadvantage in terms of manufacturing.
