Description

Technical Field

[0001] The utility model relates to the field of tools, in particular to a phacoemulsification needle installer and a phacoemulsification system. Background Art

[0002] Phacoemulsification is a cataract treatment method that surgically removes the diseased lens and implants an artificial lens. Specifically, phacoemulsification uses high-frequency ultrasound energy to crush or emulsify the diseased lens, then sucks the crushed or emulsified material out of the eye and finally implants an artificial lens, thereby achieving the effect of curing cataracts.

[0003] The equipment used in phacoemulsification is shown in Figure 2. Figure 1 , including a phacoemulsification handle 910, the phacoemulsification handle 910 is connected to a phacoemulsification needle 930, the phacoemulsification needle 930 is a hollow structure, and is used to extend into the eye to perform a suction action of a substance and transmit ultrasonic energy. During the operation, the doctor needs to drive the phacoemulsification needle 930 through the phacoemulsification handle 910. Therefore, the phacoemulsification needle 930 and the phacoemulsification handle 910 need to be tightly installed.

[0004] At present, the main Figure 2 The mounting sleeve 800 shown is used to mount the phacoemulsification needle 930 to the phacoemulsification handle 910. Specifically, the mounting sleeve 800 has a special-shaped hole 850, and the phacoemulsification needle 930 is mounted on the phacoemulsification handle 910. Figure 3 , having a special-shaped portion 935 and a threaded portion 937, and the shape of the special-shaped hole 850 matches the special-shaped portion 935. The mounting sleeve 800 loads the phacoemulsification needle 930 through the mounting portion 935, and aligns the threaded portion 937 with the threaded hole on the phacoemulsification handle 910 for threaded connection. However, the current mounting sleeve 800 is mainly a sleeve component made of plastic material. When driving the phacoemulsification needle 930 to rotate, it is easy to cause the mounting sleeve 800 itself to deform and slip, resulting in difficulty in relatively tightening the threaded portion 937 and the phacoemulsification handle.

In addition, the loading hole is a special-shaped hole, so it can also effectively prevent or avoid the problem of relative rotation between the loading hole and the phacoemulsification needle, thereby improving the stability between the main body and the phacoemulsification needle.

[0019] During the process of the main body driving the phacoemulsification needle to be installed on the phacoemulsification handle, the main body needs to be rotated so that the phacoemulsification needle can be threadedly connected to the phacoemulsification handle.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figure 4 , a phacoemulsification needle installer, comprising: a main body 500, a sleeve part 520 and a long handle part 510; the sleeve part 520 is arranged on the main body 500, the sleeve part 520 extends toward one side of the main body 500, and a loading hole 550 is arranged at the end of the sleeve part 520 away from the main body 500; the loading hole 550 is a special-shaped hole and its shape matches the special-shaped part of the phacoemulsification needle; the long handle part 510 is arranged on the side of the main body 500 and extends in a direction away from the main body 500, the long handle part 510 extends toward the side direction of the sleeve part 520 and can drive the sleeve part 520 to rotate, and the long handle part 510 is in the shape of a long handle. The main body 500 is sleeved on the phacoemulsification needle through the sleeve part 520, and after the loading hole 550 and the connecting part of the phacoemulsification needle are matched and connected, the phacoemulsification needle is successfully loaded on the main body 500, so the phacoemulsification needle can be driven by the main body 500 to be installed on the phacoemulsification handle. In addition, the loading hole 550 is a special-shaped hole, so it can also effectively prevent or avoid the problem of relative rotation between the loading hole 550 and the phacoemulsification needle, thereby improving the stability between the main body 500 and the phacoemulsification needle. In the process of the main body 500 driving the phacoemulsification needle to be installed on the phacoemulsification handle, the main body 500 needs to be rotated so that the phacoemulsification needle can be threadedly connected with the phacoemulsification handle. In this process, by applying force to the long handle 510, the main body 500 and the sleeve part 520 can be effectively driven to rotate. The long handle 510 can not only increase the torque arm when driving the main body 500 to rotate, but also compared with the traditional solution of driving the main body 500 to rotate by friction, the driving method of rotating and driving by the extended long handle 510 also has the advantages of stability and reliability, so that slipping and other phenomena can be avoided, so that the installation operation between the phacoemulsification needle and the phacoemulsification handle can be performed simply, conveniently, accurately and reliably.

[0033] In certain embodiments, reference Figure 4 There are multiple long handles 510, each of which is distributed around the sleeve 520 and extends toward the circumferential direction of the sleeve 520. The multiple long handles 510 can jointly drive the sleeve 520 to rotate in different circumferential directions of the sleeve 520, so that the sleeve 520 can be smoothly driven by the long handles 510 and rotate. In addition, the multiple long handles 510 can also provide multiple force application points for medical staff using it. Medical staff do not need to tediously spend time and effort to rotate the long handle 510 in a full circle, but can complete the predetermined rotation angle through the movement combination of each long handle 510 in sequence. Therefore, the multiple long handles 510 can also bring convenience to the medical staff using it, and ensure that the installation process between the phacoemulsification needle and the phacoemulsification handle is smoother and more reliable.

[0034] It is conceivable that there may be only one long handle portion 510 , and the specific implementation method may be adjusted accordingly according to actual needs, and is not limited here.

[0035] In certain embodiments, reference Figure 4 There are two long handles 510, and the two long handles 510 are respectively connected to opposite sides of the main body 500. The two long handles 510 can complete the full-circle rotation of the sleeve part 520 after rotating half a circle in sequence, so the action process of driving the sleeve part 520 in a full circle can be effectively simplified, thereby making the installation action between the phacoemulsification needle and the phacoemulsification handle simpler and more convenient.

[0036] It is conceivable that the long handle portions 510 may also be other quantities, such as three, four or more quantities. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0037] In certain embodiments, reference Figure 4 The sleeve portion 520 and the main body 500 are an integrated structure, and the loading hole 550 extends into and penetrates the main body 500. The integrated structure makes the sleeve portion 520 and the main body 500 more stable, thereby ensuring that the main body 500 can smoothly drive the sleeve portion 520 to rotate together when driven by the long handle portion 510, and the relative shaking problem between the two is not likely to occur when the two move together, thereby ensuring that the phacoemulsification needle can be accurately installed on the phacoemulsification handle.

[0038] In certain embodiments, reference Figure 4 The long handle 510 is welded to the outer wall of the main body 500 and connected to the main body 500 as a whole. The welding between the long handle 510 and the main body 500 can effectively mount the long handle 510 on the outer periphery of the main body 500 as a whole, thereby ensuring that the long handle 510 is not prone to slipping relative to the main body 500 when subjected to force.

[0039] In certain embodiments, reference Figure 4 , the maximum length of the long handle 510 is greater than the maximum length of the sleeve 520. The long handle 510 has a greater maximum length, so when the sleeve 520 drives the phacoemulsification needle to rotate, the long handle 510 not only has a sufficient position for contacting the user, but also has a sufficiently long lever arm length, so it can effectively bring labor-saving effects to the user, thereby allowing the user to more simply and conveniently perform rotational driving between the main body 500, the sleeve 520, and the phacoemulsification needle.

[0040] It is conceivable that the long handle portion 510 may also have the same length as the sleeve portion 520. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0041] In certain embodiments, reference Figure 4 , the long handle portion 510 and the sleeve portion 520 are both in the shape of a long cylinder, and the central axis of the long handle portion 510 and the central axis of the sleeve portion 520 are intertwined. The long cylinder-shaped long handle portion 510 has a longer curved side wall, so it can provide a larger area and more convenient force application position for the user. The central axes of the sleeve portion 520 and the long handle portion 510 are intertwined, which can ensure that the long handle portion 510 can apply torque to the sleeve portion 520 when subjected to force, thereby ensuring that the long handle portion 510 can smoothly drive the sleeve portion 520 to rotate.

[0042] In certain embodiments, reference Figure 4 The sleeve portion 520, the main body 500 and the long handle portion 510 are all made of stainless steel. Compared with the conventional rubber material installer, the stainless steel material has higher rigidity, so it can effectively avoid the problem of self-deformation when driving the phacoemulsification needle for installation, thereby ensuring that the installation operation of the phacoemulsification needle can be carried out more stably and reliably.

[0043] In certain embodiments, reference Figure 5 The loading hole 550 is a square hole and has at least one straight inner side wall. The square hole can drive the plane part of the phacoemulsification needle to rotate through its straight inner side wall, thereby smoothly achieving the effect of driving the phacoemulsification needle to perform threaded screwing movement, thereby completing the installation operation between the phacoemulsification needle and the phacoemulsification handle.

[0044] The second aspect of the utility model provides an embodiment of a phacoemulsification system, including the above-mentioned phacoemulsification needle installer. The main body 500 is sleeved on the phacoemulsification needle through the sleeve portion 520, and after the loading hole 550 and the connecting part of the phacoemulsification needle are matched and connected, the phacoemulsification needle is successfully loaded on the main body 500, so the phacoemulsification needle can be driven by the main body 500 to be installed on the phacoemulsification handle. In addition, the loading hole 550 is a special-shaped hole, so it can also effectively prevent or avoid the problem of relative rotation between the loading hole 550 and the phacoemulsification needle, thereby improving the stability between the main body 500 and the phacoemulsification needle. In the process of the main body 500 driving the phacoemulsification needle to be installed on the phacoemulsification handle, the main body 500 needs to be rotated so that the phacoemulsification needle can be threadedly connected with the phacoemulsification handle. In this process, by applying force to the long handle portion 510, the main body 500 and the sleeve portion 520 can be effectively driven to rotate. The long handle portion 510 can not only increase the torque arm when driving the main body 500 to rotate, but also compared with the traditional solution of driving the main body 500 to rotate by friction, the driving method of rotationally driving by the extended long handle portion 510 has the advantages of stability and reliability. Therefore, slipping and the like can be avoided, thereby making it possible to simply, conveniently, accurately and reliably perform the installation operation between the ultrasonic emulsification needle and the ultrasonic emulsification handle.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
