Description

Technical Field

[0001] This utility model relates to the field of medical equipment assistance, specifically a hysteroscopy device for multi-angle observation. Background Technology

[0002] Hysteroscopy involves inserting the endoscope into the uterine cavity, providing a magnified view of the observed area. It is the preferred diagnostic method for gynecological bleeding disorders and intrauterine lesions. During uterine examinations and treatments, hysteroscopic equipment, through its advanced design, provides a visual field within the uterine cavity for physicians to examine lesion areas. However, an existing integrated hysteroscope (publication number: CN213665167U) has the following drawbacks and requires further improvement.

[0003] Most common hysteroscopic devices use a single-view observation method, which can only observe different intrauterine fields by rotating the device or adjusting the angle. Each time the angle of the device is adjusted or the device is rotated, it requires manual operation by the doctor, which is quite cumbersome.

[0004] This repetitive process not only increases the complexity of the procedure and causes patient discomfort, but prolonged operation can also lead to fatigue, thereby affecting the doctor's operational accuracy and the patient's examination experience. Utility Model Content

[0005] The main objective of this invention is to provide a hysteroscopic device for multi-angle observation, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hysteroscopic device for multi-angle observation, wherein a guide sheath is provided at the top of the main body, a front end catheter is provided inside the guide sheath, a rear end catheter is provided at the tail of the front end catheter, an interface connector is provided at the tail of the rear end catheter, the interface connector is connected to a control forceps through the catheter, a cleaning channel is provided inside the main body, a control channel is provided inside the main body, the cleaning channel passes through the front end catheter and has a saline outlet at the front end, a light source is provided outside the front end catheter, a flexible lens A is provided outside the front end catheter, a flexible lens B is provided outside the front end catheter, and a steering mechanism is installed at the bottom of the flexible lens A and the flexible lens B.

[0007] Preferably, the outer wall of the front-end conduit is provided with a fixing groove, and the flexible lens A and the flexible lens B are respectively fixed to the front-end conduit by fixing buckles, the fixing buckles being made of elastic material.

[0008] Preferably, the cleaning channel is a flexible pipe and is connected to the front-end conduit via a sealing connector made of silicone material.

[0009] Preferably, the steering mechanism includes two steering wheels respectively mounted on the bottom of the soft lens A and the soft lens B. The steering wheels are connected to the control caliper by a steel wire rope with a diameter of 0.8 mm.

[0010] Preferably, the rear conduit and the interface connector are connected by a quick-connect fitting, which has a snap-fit ​​structure and a connection diameter of Φ4mm.

[0011] Preferably, the soft lens A and the soft lens B are adjustable focus lenses. The adjustable focus lens is connected to the steering mechanism via a micro motor with a power of 1W. The motor is connected to the control clamp via a wire.

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

[0013] The device body, guide sheath, and front catheter are connected via a rationally designed method, ensuring the front catheter can be securely inserted into the uterus and guaranteeing operational stability. Combined with the precise design of the rear catheter, interface connector, and control forceps, doctors can easily observe different areas of the uterine cavity without frequently adjusting the device angle.

[0014] The design of the cleaning channel and saline outlet effectively removes any haze or secretions that may occur during hysteroscopic observation, maintaining a clear field of vision. Simultaneously, the light source, fixed externally to the front catheter, ensures uniform illumination, further enhancing the brightness and clarity of the field of vision. The coordinated use of the control channel and steering mechanism allows doctors to more precisely control the lens angle, easily identifying potential lesions and ensuring accurate diagnosis and effective treatment.

[0023] Example

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A hysteroscopic device for multi-angle observation includes a guide sheath 2 at the top of the main body 1, a front catheter 3 inside the guide sheath 2, a rear catheter 4 at the tail of the front catheter 3, an interface connector 5 at the tail of the rear catheter 4, and a control forceps 6 connected to the interface connector 5 via the catheter. The main body 1 has a cleaning channel 7 and a control channel 8 inside. The cleaning channel 7 extends through the front catheter 3 and has a saline outlet 12 at its front end. A light source 9 is located outside the front catheter 3. Flexible lenses A1101 and B1102 are located outside the front catheter 3. A steering mechanism 10 is installed at the bottom of both flexible lenses A1101 and B1102.

[0026] The process is as follows:

[0027] Connect the quick-connect connector (Φ4mm±0.05) to the flushing pump and complete the airtightness test (pressure 0.3MPa maintained for 10s without leakage). The guide sheath moves at a uniform speed of 3mm / s. Rapidly advance(The alarm threshold of the resistance monitoring system is set to 2N). When encountering resistance at the uterine horn, the flexible section undergoes controllable bending (curvature radius ≥15mm), and the light source module is preheated to a color temperature of 5600K.

[0028] The left knob of the control clamp drives the soft lens A to scan horizontally (0-60° continuously adjustable), while the right knob simultaneously controls the vertical movement of the soft lens B (-30° to +45°). A miniature gripper (1.8mm in diameter) is then inserted through the control channel, working in conjunction with dual-lens stereo vision positioning (positioning accuracy 0.2mm).

[0029] The guide sheath is made of biocompatible polycarbonate material, with a spiral guide groove (3mm lead) on its inner surface, forming a sliding pair with the limiting protrusion of the front catheter. The front catheter is divided into three sections: a rigid section (20mm from the tip) with an internal stainless steel reinforcing ring to ensure guiding stability during the initial insertion stage.

[0030] Transition section (50mm in length): Gradual hardness design (Shore hardness decreases from 85A to 75A)

[0031] Flexible section (80mm in length): integrates optical components and can withstand 180° bending.

[0032] The soft lenses A and B are installed at a 30° offset angle, achieved through the principle of geometric optics.

[0033] Total field of view coverage = 2 × (FOV - overlap area), where: FOV = 120°, the overlap area is designed to be 20° with an effective coverage angle of 200°, and the lens bracket is made of shape memory alloy, which automatically restores the preset curvature under body temperature.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
