Description

Technical Field

[0001] The present application relates to an ophthalmic surgical probe. Background Art

[0002] A surgical probe refers to a tool used to guide implantable materials or other tools during surgery. Among the probes used in ophthalmology, the probe needs to be used to detect the tear duct, and then inserted into the tear duct, and the required components are introduced by stretching the stretch wire. The existing stretch wire needs to be wrapped around the probe, which makes the steric resistance at the wrapping too large, affecting the operation and the comfort of the patient. On the other hand, it is impossible to determine the specific position and direction of the probe inserted into the tear duct, making it difficult to use the operator's experience of the tear duct shape, affecting the efficiency of the operation, and easily causing wounds on the patient's surgical site. Utility Model Content

[0003] In order to solve the above problems, the present application proposes an ophthalmic surgical probe, including two first and second guide wires arranged side by side and abutting each other, a first end positioning head and a second end positioning head are respectively arranged at both ends of the first and second guide wires, the first and second end positioning heads are respectively fixedly connected to the first and second guide wires, a first arc portion is arranged at the ends of the first and second guide wires corresponding to the first end positioning head, and a second arc portion is arranged at the ends of the first and second guide wires corresponding to the second end positioning head, and the bending directions of the first and second arc portions are the same or opposite. The present application adopts the first and second guide wires arranged in a superimposed manner for clamping the traction line, and then uses the first and second end positioning heads to avoid pulling out one side during the traction process. Since the first and second arc portions are arranged in the same or opposite manner, the orientation of the insertion side can be seen from the operating side.

[0004] Preferably, the first guide wire and the second guide wire can be separated from each other.

[0005] Preferably, the first guide wire and the second guide wire are both made of memory steel wire.

[0006] Preferably, the first guide wire and the second guide wire respectively include a straight segment and a first arc portion and a second arc portion arranged on both sides of the straight segment.

[0007] Preferably, the first arc-shaped portion and the second arc-shaped portion each include a transition segment connected to the straight segment, and a U-shaped connecting segment is arranged on the transition segment, and the U-shaped connecting segment is symmetrically arranged relative to the middle thereof. The U-shaped connecting segment is arranged on both sides of the present application, and when the surgical probe is inserted, the U-shaped connecting segment is first used to insert into the operating part, and the U-shaped connecting segment itself will not affect the progress of the surgical operation, nor will it cause damage to the operating part.

[0008] Preferably, the opening direction of the U-shaped connecting segment is arranged toward the straight line segment.

[0009] Preferably, a traction portion for clamping the traction line is alternately arranged between the first guide wire and the second guide wire corresponding to the position of the U-shaped connecting section.

[0010] Preferably, the connection positions of the first end locating head and / or the second end locating head and the first guide wire and the second guide wire are arranged non-correspondingly to their outward extension directions, so that a staggered traction portion is formed between the first guide wire and the second guide wire. The staggered arrangement of the present application has two advantages. On the one hand, it is convenient to clamp the traction line, and on the other hand, it improves the clamping stability of the clamping line.

[0011] This application can bring the following beneficial effects:

[0012] 1. The present application adopts a first guide wire and a second guide wire that are superimposed on each other to clamp the traction line, and then utilizes a first end positioning head and a second end positioning head to avoid pulling one side out during traction. Since the first arc-shaped portion and the second arc-shaped portion form the same or opposite settings, the orientation of the insertion side can be seen from the operating side.

[0013] 2. The present application provides U-shaped connecting sections on both sides. When inserting the surgical probe, the U-shaped connecting section is first inserted into the operating part. The U-shaped connecting section itself will not affect the progress of the surgical operation, nor will it cause damage to the operating part.

[0014] 3. The staggered arrangement of the present application has two advantages. On the one hand, it facilitates the clamping of the traction line. On the other hand, it improves the clamping stability of the clamping line. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to clearly illustrate the technical features of the present solution, the present application is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0020] In the first embodiment, if Figure 1 As shown, an ophthalmic surgical probe comprises two first guide wires 1 and second guide wires 2 arranged side by side and abutting each other, a first end positioning head 3 and a second end positioning head 4 are respectively arranged at both ends of the first guide wire 1 and the second guide wire 2, the first end positioning head 3 and the second end positioning head 4 are respectively fixedly connected to the first guide wire 1 and the second guide wire 2, a first arc portion 5 is arranged at the end of the first guide wire 1 and the second guide wire 2 corresponding to the first end positioning head 3, and a second arc portion 6 is arranged at the end of the first guide wire 1 and the second guide wire 2 corresponding to the second end positioning head 4, and the bending directions of the first arc portion 5 and the second arc portion 6 are the same or opposite.

[0021] When in use, a rubber tube 7 is sleeved on the outside of the first guide wire 1 and the second guide wire 2, and then a traction line is set between the first guide wire 1 and the second guide wire 2, and the clamping is completed, and then the tear duct can be probed, and then the internal components can be operated using the traction line 12. Since there is a relationship between the bending directions of the first arcuate portion 5 and the second arcuate portion 6, the direction of the insertion side can be judged from the direction of the arcuate portion on the operating side, which is more convenient for related operations.

[0022] In the second embodiment, if Figure 1-3 As shown, an ophthalmic surgical probe comprises two first guide wires 1 and second guide wires 2 arranged side by side, a first end positioning head 3 and a second end positioning head 4 are respectively arranged at both ends of the first guide wire 1 and the second guide wire 2, the first end positioning head 3 and the second end positioning head 4 are respectively fixedly connected to the first guide wire 1 and the second guide wire 2, a first arcuate portion 5 is arranged at the end of the first guide wire 1 and the second guide wire 2 corresponding to the first end positioning head 3, and a second arcuate portion 6 is arranged at the end of the first guide wire 1 and the second guide wire 2 corresponding to the second end positioning head 4, and the bending directions of the first arcuate portion 5 and the second arcuate portion 6 are the same or opposite. The first guide wire 1 and the second guide wire 2 can be separated. The first guide wire 1 and the second guide wire 2 are both guide wires made of memory steel wire. The first guide wire 1 and the second guide wire 2 respectively comprise a straight segment 8 and a first arcuate portion 5 and a second arcuate portion 6 arranged on both sides of the straight segment 8. The first arcuate portion 5 and the second arcuate portion 6 each include a transition segment 9 connected to the straight segment 8, on which a U-shaped connecting segment 10 is arranged, and the U-shaped connecting segment 10 is symmetrically arranged relative to the middle thereof. The opening direction of the U-shaped connecting segment 10 is arranged toward the straight segment 8. A traction portion 11 for clamping a traction line is staggered between the first guide wire 1 and the second guide wire 2 corresponding to the position of the U-shaped connecting segment 10. The connection position of the first end positioning head 3 and / or the second end positioning head 4 with the first guide wire 1 and the second guide wire 2 is not arranged corresponding to the outward extension direction thereof, so that a staggered traction portion 11 is formed between the first guide wire 1 and the second guide wire 2.

[0023] When in use, a rubber tube 7 is sleeved on the outside of the first guide wire 1 and the second guide wire 2, and the first guide wire 1 and the second guide wire 2 are used to separate the two, and then the traction line 12 is set between the first guide wire 1 and the second guide wire 2, and the clamping is completed, and then the tear duct can be probed, and then the built-in component can be operated using the traction line. Since there is a relationship between the bending directions of the first arc portion 5 and the second arc portion 6, the direction of the insertion test can be judged from the direction of the arc portion on the operating side, which is more convenient for related operations.
