Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laser laryngeal microsurgery instrument. Background Art

[0002] Currently, laser surgery is mostly used clinically to remove diseased tissues in the throat. Laser surgery usually requires the use of a fiber optic guide to guide the laser fiber so that the laser fiber can reach the designated position smoothly.

[0003] In order to ensure the accuracy of the surgical operation, there is a solution in the existing technology to complete the throat surgery by using a microscope for observation and a supported laryngoscope. During the operation, the microscope is far away from the patient, and the length of the hollow guide tube of the current fiber optic guide is usually 15-20cm, which is short. The doctor needs to stretch his hand for a long time during the operation so that the front end of the fiber optic guide can smoothly reach the designated position. This makes some doctors easily feel tired during the actual operation, which is not suitable for supported laryngoscope surgery and cannot ensure the quality of the operation. Utility Model Content

[0021] As a further improvement of the above technical solution, the angle between the first pipe section and the second pipe section is 100-130 degrees.

[0022] As a further improvement of the above technical solution, the angle between the first pipe segment and the second pipe segment is 120 degrees.

[0023] As a further improvement of the above technical solution, the first pipe segment and the second pipe segment are transitioned through an arc-shaped pipe segment.

[0024] Through the above technical solution, the arc-shaped tube segment is arranged between the second tube segment and the first tube segment, which can play an arc-shaped transition between the second tube segment and the first tube segment, thereby avoiding a sharp transition between the second tube segment and the first tube segment of the hollow guide tube, thereby reducing the probability of the hollow guide tube damaging human tissue.

[0035] Reference Figure 1 , a laser laryngeal microsurgery instrument comprises a laryngeal handle 100 and a hollow guide tube 200 .

[0036] Specifically, in the present embodiment, the laryngeal handle 100 includes a handle body 110 , a catheter passing portion 120 and a locking structure 130 .

[0037] Specifically, in this embodiment, the handle body 110 is configured as a flat handle structure commonly used in the art. In other embodiments, the handle body 110 may also be configured as a double-forked handle, etc. Those skilled in the art may select the specific structure of the handle body 110 according to actual needs.

[0038] The catheter passing portion 120 is disposed at the front end of the handle body 110 , and the catheter passing portion 120 is provided with a through hole penetrating along the front-to-back direction.

[0039] The catheter passing portion 120 is further provided with a threaded hole, which is communicated with the through hole provided in the catheter passing portion 120 .

[0040] Specifically, in this embodiment, the locking structure 130 is configured as a screw structure, the locking structure 130 is threadedly connected to the threaded hole provided in the catheter passing portion 120 , and the end of the locking structure 130 extends into the through hole provided in the catheter passing portion 120 .

[0041] Specifically, a rotating head is provided at one end of the locking structure 130 away from the through hole opened in the catheter passing part 120, and a rotating friction pattern is provided on the side wall of the rotating head. The rotating friction pattern can be used to increase the friction between the doctor's hand and the locking structure 130, thereby preventing the doctor from slipping when rotating the locking structure 130 to a great extent.

[0042] The hollow guide tube 200 is a hollow tubular structure. The hollow guide tube 200 is used to guide the laser optical fiber. The hollow guide tube 200 is required to be smooth, without bevel edges and burrs, so that the hollow guide tube 200 is not easy to cause damage to normal human tissue after entering the human body. The front end of the laser optical fiber extends out of the hollow guide tube 200, and laser surgery can be performed.

[0043] The hollow guide tube 200 can slide in the front-to-back direction relative to the catheter passing portion 120 , so that the relative position of the hollow guide tube 200 and the catheter passing portion 120 can be adjusted to suit different doctors.

[0044] The hollow guide tube 200 is a replaceable component. The hollow guide tube 200 has a variety of different length specifications.

In other embodiments, the total length of the hollow guide tube 200 can also be set to 25 cm, 26 cm, etc. Medical staff can select hollow guide tubes 200 of different specifications according to actual needs.

[0045] The length of the hollow guide tube 200 is set between 25-30 cm. During actual operation, the doctor can perform supported laryngoscopy surgery in a relatively comfortable posture. During long-term work, the doctor's hands are less likely to get tired, which is more suitable for supporting laryngoscopy surgery and can greatly improve the quality of the operation.

[0046] One end of the locking structure 130 abuts against the outer circumferential surface of the hollow guide tube 200 , so that the locking structure 130 fixes the hollow guide tube 200 .

[0047] Specifically, in this embodiment, the rear end of the hollow guide tube 200 is fixedly mounted with an optical fiber fixing structure 240. Specifically, in this embodiment, the optical fiber fixing structure 240 is configured as a snap-fit ​​optical fiber structure. The optical fiber fixing structure 240 is used to fix the relative position of the optical fiber and the rear end of the hollow guide tube 200, thereby preventing relative displacement between the optical fiber and the hollow guide tube 200 during movement.

[0048] Specifically, in this embodiment, the hollow guide tube 200 is a straight tubular structure.

[0049] Embodiment 2:

[0050] Reference Figure 2 The present embodiment is different from the first embodiment in that the hollow guide tube 200 is configured as a bent tubular structure. Specifically, the hollow guide tube 200 includes a first tube section 210 , an arc-shaped tube section 230 and a second tube section 220 .

[0051] The first tube segment 210, the arc-shaped tube segment 230 and the second tube segment 220 are connected in sequence. The arc-shaped tube segment 230 is arranged in an arc shape, and the arc-shaped tube segment 230 is arranged between the second tube segment 220 and the first tube segment 210, and can play an arc transition between the second tube segment 220 and the first tube segment 210, thereby avoiding a sharp transition between the second tube segment 220 and the first tube segment 210 of the hollow guide tube 200, thereby reducing the probability of the hollow guide tube 200 damaging human tissue.

[0052] Specifically, in the present embodiment, the second pipe segment 220 and the first pipe segment 210 are inclined. Specifically, in the present embodiment, the angle between the second pipe segment 220 and the first pipe segment 210 is set to 120 degrees. In other embodiments, the angle between the second pipe segment 220 and the first pipe segment 210 can also be set to between 100-130 degrees. Those skilled in the art can select the size of the angle between the second pipe segment 220 and the first pipe segment 210 according to actual needs.

[0053] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
