Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical endoscopes, in particular to an electronic endoscope adjustable front end and an endoscope. BACKGROUND

[0002] In modern medicine, endoscopic technology is widely used in diagnosis and treatment, especially in minimally invasive surgery. Traditional optical endoscopes have fixed viewing angles due to the use of optical systems, which cannot be adjusted as needed, making them less operable in some complex surgical environments, especially in narrow and limited space lesion areas.

[0003] Although the viewing angle of the traditional electronic endoscope can be adjusted by electronic means, it usually has a fixed viewing angle range, and when adjusting the viewing angle, the bending radius is too large to adapt to the narrow space of the lesion area, especially when checking and treating in small joints such as joint cavities, there are problems such as limited field of view and inconvenient operation.

[0004] Therefore, there are still limitations in the application of endoscopes in narrow lesion areas in the prior art. In order to overcome these problems, an electronic endoscope adjustable front end and an endoscope are proposed. SUMMARY

[0005] The purpose of the present application is to provide an electronic endoscope adjustable front end and an endoscope, which improves the surgical operation field of view in narrow spaces.

[0008] A plurality of mounting through holes are formed on the outer wall of the support tube, the adjusting rod is movably mounted in the mounting through hole, and a connecting ball head is arranged on the distal end surface of the adjusting rod.

[0009] On the other hand, an electronic endoscope is proposed, which has a handle, and an electronic endoscope adjustable front end is mounted on the handle.

[0010] Advantages:

[0011] The present application is provided with an image acquisition unit in the movable front end, and the adjusting angle can be flexibly adjusted as needed, which can realize image acquisition of tissues and lesions at different angles, better adapt to different human structures and lesion positions, ensure image acquisition quality, reduce errors and blind areas, and improve the accuracy of surgery and diagnosis.

[0012] The adjusting rod made of elastic material can correct position deviation when the angle changes, and avoid mechanical damage caused by improper operation;

[0013] The heat shrinkable sleeve is arranged outside the endoscope, and protects the support tube and the movable front end from external impact or abrasion, thereby improving the service life of the endoscope and the safety of the patient.

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] It should be noted that the "distal end" is the end far from the operator, and the "proximal end" is the end close to the operator.

[0026] Embodiment 1, Figure 5 As a structural schematic diagram of an electronic endoscope adjustable lens in some embodiments, the electronic endoscope adjustable lens provided by the present disclosure is used for endoscopic surgery and mainly used to solve the limitation of the view angle of the endoscope in a narrow lesion area. In some embodiments, the electronic endoscope adjustable lens comprises an insertion part 2, the insertion part 2 comprises a support tube 21, a movable front end 22 and an adjusting rod 5; the movable front end 22 is internally provided with an image acquisition unit 23, and three circularly distributed opening grooves 221 are formed on the proximal end side surface of the movable front end 22, and a spherical groove 222 is arranged in each opening groove 221.

[0027] Three mounting through holes 211 are formed on the outer wall of the support tube 21, and the adjusting rod 5 is movably mounted in the mounting through hole 211; in this way, sufficient support is provided for the adjusting rod 5, and the adjusting rod 5 can slide in the mounting through hole 211 to complete adjustment; further, the mounting through hole 211 can be integrally injection molded with plastic, or can be made of metal material, and when the metal material is used, three thin tubes containing the mounting through hole 211 can be arranged on the outer side or the inner side of the support tube 21 body by welding for processing convenience, and the fixing mode can be welding or glue bonding.

[0028] As shown in Figure 7 The movable front end 22 is supported and mounted by the three adjusting rods 5, the distal end face of the adjusting rod 5 is provided with a connecting ball head 51, the connecting ball head 51 is movably mounted in the spherical groove 222, and the opening groove 221 can provide more adjustment angles for the connecting ball head 51 and its adjusting rod 5; the adjusting rod 5 is an elastic rod that can slightly deform, and the material of the adjusting rod 5 can be stainless steel, nickel-titanium alloy, titanium alloy or the like.

[0029] The three adjusting rods 5 complete the support of the movable front end 22, and the angle of the movable front end 22 is adjusted by adjusting the relative positions of the three adjusting rods 5; specifically, the connecting points of the three adjusting rods 5 and the spherical groove 222 are divided into three points a, b and c, and when a, b and c are in the same plane position, the movable front end 22 is in a horizontal position.

[0030] When the point a moves distally relative to the points b and c, the points b and c move synchronously backward, and the movable front end 22 rotates toward the point a. Similarly, when the point b or c moves distally, the movable front end 22 also rotates toward the point b or c. When the point a moves proximally relative to the points b and c, the points b and c move synchronously forward, and the movable front end 22 reversely rotates toward the point a. Similarly, when the point b or c moves proximally, the movable front end 22 also reversely rotates toward the point b or c. It can be understood that the adjusting rod 5 has a certain elasticity, and the position deviation caused by the change of the angle can be corrected by elastic deformation when the movable front end 22 rotates.

[0031] In some embodiments, the rotation angle of the adjusting rod 5 toward the three points a, b and c is -15°-15°, so that a suitable viewing angle can be obtained while ensuring the supporting effect of the adjusting rod 5 on the movable front end 22, and the adjusting rod 5 will not be deformed excessively.

[0032] In some embodiments, a heat shrink sleeve 3 is arranged outside the insertion part 2, and the heat shrink sleeve 3 covers the support tube 21 and the movable front end 22. This design can ensure insulation and seal the gap between the support tube 21 and the movable front end 22, and further, the heat shrink sleeve 3 can also assist in supporting and fixing the movable front end 22, thereby ensuring the stability of the movable front end 22.

[0033] As shown in Figures 1-2 , the support tube 21, as a support component, is connected to the connecting end 14 arranged on the handheld part 1 at the proximal end. It should be noted that the fixing mode of the support tube 21 and the connecting end 14 can be selected from screwing, gluing, interference fit and the like.
