Description

Technical Field

[0001] This utility model relates to the field of endoscopy, specifically to a cystoscope. Background Technology

[0002] A cystoscope is a type of endoscope, similar in shape to a urethral probe. It consists of four parts: an electron sheath, an examination endoscope, a procedure and ureteral catheterization endoscope, and a cystoscope core. Accessories include an electrocautery device, a cutting tool, and biopsy forceps. In recent years, the illumination system of cystoscopes has been improved, featuring a cold light source box. Strong, cold light is reflected and transmitted to the inside of the bladder via an optical fiber beam, replacing the bulb illumination at the tip of the cystoscope sheath. This provides advantages such as better illumination, clearer vision, and adjustable dimming.

[0003] Previously, cystoscopes used in major hospitals were very expensive and therefore required permanent or repeated use. Furthermore, due to their high price, they needed routine maintenance and sterilization. Therefore, with the technological advancements in cystoscopes, disposable cystoscopes are now available. However, disposable cystoscopes currently have at least the following problems:

[0004] 1. The existing cystoscope has a three-way connector, one for biopsy forceps, one for ventilation, and one for water. However, in actual clinical practice, the three-way connector is almost never used. This not only wastes production costs, but also occupies three sides of the cystoscope, taking up surface space.

[0005] 2. The existing three-way cystoscope interface also causes inconvenience for doctors during use, interferes with doctors' operations, and has low operational flexibility. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing cystoscopes with three-way interfaces are not only not used in daily life, but also occupy space and affect doctors' operations.

[0007] To solve the above-mentioned technical problems, the present invention provides a cystoscope comprising:

[0008] The main body shell has an inner cavity; the surface of the main body shell has an arc-shaped groove communicating with the inner cavity; one end of the main body shell has a through hole; the other end of the main body shell has a pipe hole; the through hole and the pipe hole are on the same axis;

[0009] A movable tube is movably installed in the inner cavity of the main body shell; and the movable tube, the tube hole, and the through hole are on the same axis.

[0010] A first connecting pipe, one end of which passes through the arc-shaped groove and communicates with the side of the movable pipe;

[0011] A second connecting tube passes at least partially through the through hole and is movably connected to one end of the movable tube;

[0012] An outer tube, one end of which is fixedly or movably connected to the tube hole;

[0013] An inner tube is located inside the outer tube, and one end of the inner tube is movably connected to the other end of the movable tube; a camera and a light are installed at the other end of the inner tube.

[0014] The main housing has a fixedly connected display connector, which is connected to the camera and the lighting lamp wires respectively.

[0015] In a preferred embodiment of the cystoscope of this utility model, the second connecting tube has a first tube seat fixedly connected to one end inside the main body shell; one end of the movable tube is movably connected to the first tube seat; the inner tube has a second tube seat fixedly connected to one end inside the main body shell, and the other end of the movable tube is movably connected to the second tube seat.

[0016] In a preferred embodiment of the cystoscope of this utility model, the main body shell has a first C-shaped hand grip position and a second C-shaped hand grip position that are fixedly connected.

[0017] In a preferred embodiment of the cystoscope of this utility model, the first tube seat and the second tube seat each have a sealing gasket.

[0018] As a preferred embodiment of the cystoscope of this utility model, it includes a fixing nut, which is detachably connected to the main body shell; one end of the outer tube and one end of the inner tube respectively pass through the fixing nut.

[0019] In a preferred embodiment of the cystoscope of this utility model, the inner cavity has a first connecting groove and a second connecting groove that are fixedly connected to the main body shell, the first tube seat is movably installed in the first connecting groove, and the second tube seat is movably installed in the second connecting groove. Beneficial effects

[0020] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:

[0021] This utility model of a cystoscope features a movable tube movably installed within the main body shell, allowing the movable tube to rotate at least partially within the shell. An arc-shaped groove in the main body shell allows a first connecting tube to pass through and provides space for its reciprocating movement. During use, the first connecting tube can rotate at least partially around the movable tube as its axis, allowing it to be positioned either directly above or to the left or right of the main body shell. This design reduces the space occupied by the main body shell and provides doctors with greater flexibility in clinical applications. Doctors can rotate the first connecting tube to a position or direction that does not obstruct their operation, depending on the patient's condition or whether they are left- or right-handed. This facilitates operation and improves flexibility.

[0022] This utility model of cystoscope, through the setting of a first C-shaped grip position and a second C-shaped grip position, allows the index and middle fingers to be positioned in the first C-shaped grip position and the second C-shaped grip position respectively when the doctor grasps the main body shell, which further improves the convenience of the doctor's hand and makes it easier for the doctor to exert force.
