Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a three-dimensional steering handle of a periodontal endoscope. Background Art

[0002] Periodontal disease is relatively common, and the commonly used methods are scaling and root planing. The periodontium is cut open with a scalpel and a flap is opened to expose the subgingival root surface tartar. After the flap is opened, the tartar is removed under direct vision. However, this surgical method has the disadvantages of heavy damage to the patient, great pain, long postoperative healing time and inability to eat well. The existing technology has developed a periodontal endoscope to treat periodontal disease without performing a periodontal flap, allowing doctors to treat periodontal disease in a minimally invasive way;

[0003] After the existing periodontal endoscope is inserted into the patient's mouth, the user needs to manually rotate the handle to view the situation inside the mouth. During manual rotation, the rotation angle is often too large or the periodontal position to be detected is lost during rotation, resulting in the need to find the periodontal position multiple times, causing low efficiency for the user and discomfort for the patient.

[0004] In view of the above problems, a three-dimensional steering handle of a periodontal endoscope is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a three-dimensional steering handle for a periodontal endoscope, which solves the problem in the background art that the commonly used periodontal endoscope treatment requires the user to manually rotate the handle to adjust the position of the metal tube to find the treatment point for periodontal disease.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a three-dimensional steering handle of a periodontal endoscope, comprising: a handle rod; a connecting sleeve fixedly connected to the front end of the handle rod; a reinforcing rod detachably connected to the connecting sleeve; a rotating mechanism located inside the reinforcing rod; a metal tube fixedly connected to the rotating mechanism; the rotating mechanism comprises a steering groove, a steering rod, a steering gear, a first motor, a cam and a clamping piece, a connecting sleeve is fixedly installed on the front section of the handle rod, a reinforcing rod is provided inside the connecting sleeve, a steering groove is provided inwardly at one end of the reinforcing rod away from the connecting sleeve, a first motor is embedded and fixedly connected inside the steering groove, an output shaft of the first motor is fixedly connected to the cam, an outer side wall of the cam is integrally formed with a clamping piece, a through-type auxiliary hole is provided on the outer side wall of the reinforcing rod, a steering rod is rotatably connected inside the auxiliary hole, a steering gear matched with the clamping piece is fixedly connected to the outer side wall of the steering rod, and a metal tube for detection is fixedly connected to the bottom end of the steering rod.

[0007] As a further description of the above technical solution: a water pipe groove is opened inside the reinforcing rod, the metal tube includes an outer tube, an inner tube and a lighting optical fiber, the interior of the inner tube is fixedly connected to the lighting optical fiber, the top end of the outer tube is fixedly connected to a catheter, the catheter passes through the steering rod, the top end of the catheter is rotatably connected to a water pipe, and the water pipe passes through the water pipe groove.

[0008] As a further description of the above technical solution: the interior of the connecting sleeve is rotatably connected to a reeling rod, the water pipe is wound around the outer side wall of the reeling rod, and the outer side wall of the reeling rod is fixedly connected to a torsion spring.

[0009] As a further description of the above technical solution: a water tank is provided behind the handle rod, the water pipe passes through the handle rod, and one end of the water pipe away from the conduit is fixedly connected to the water tank.

[0010] As a further description of the above technical solution: a second motor is fixedly connected to the interior of the connecting sleeve, and an output shaft of the second motor is fixedly connected to the rear end of the reinforcing rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention provides a three-dimensional steering handle for a periodontal endoscope, in which a cam is driven to rotate by a first motor. The engaging piece on the cam contacts the steering gear when the cam rotates one circle, allowing it to rotate an angle, thereby driving the steering rod to rotate a certain angle, driving the metal tube to rotate, and realizing all-round detection. It can also avoid the traditional situation where the position correction is difficult or the rotation angle is large and multiple corrections are required to find the exact point.

[0014] 2. The present invention provides a three-dimensional steering handle for a periodontal endoscope, in which a water pipe is wound around a winding rod, and the water pipe is rotatably connected to a catheter. When the reinforcing rod is rotated to detect the periodontal interior in multiple directions, the water pipe can be extended with the rotation, and is wound up by a torsion spring after being reset, thereby avoiding the situation of winding the water pipe during traditional detection, and not delaying water pressure cleaning, making it more convenient for users.
