Description

Imaging module and hysteroscope

technical field

The invention relates to the technical field of hysteroscopy, in particular to an imaging module and a hysteroscope.

Background technique

Hysteroscopy is used for examination and treatment within the uterine cavity. When in use, the lens of the hysteroscope can magnify and observe the parts in the uterine cavity. Surgical instruments can be operated on the uterine cavity through a hysteroscope. From the inspection point of view, hysteroscopy is the preferred inspection instrument for gynecological bleeding diseases and intrauterine lesions.

The hysteroscope should be rotatable to increase the overall field of view for a comprehensive examination of the uterus. In use, when the camera at the front end of the hysteroscope is rotated, the horizontal line of the camera is also rotated relative to the patient's anatomy. In order to compensate for this, the rotation angle is generally recorded by rotating the gear structure and the potentiometer at the operating part of the hysteroscope, and the embedded software in the image signal processing board will read the signal and perform corresponding compensation.

Moreover, the angle of view (DOV) of the hysteroscope should also be inclined to meet clinical needs. Generally, the DOV should be 0°, 12°, 20° to 30° to meet different procedural needs. Most conventional hysteroscopes meet the needs of various viewing angles by tilting the tip or implementing a prismatic structure. However, if it is realized by adding a prism, the manufacturing cost is increased, and how to position the prism during production is also a technical problem, which makes it difficult to manufacture. Additionally, the leading end of the hysteroscope is a sloping tip, which makes inserting the tip into the cervix of the uterus relatively difficult and may damage the tip during insertion.

Therefore, there is a need for a hysteroscope with multiple viewing angles that is easy to manufacture and use.

Detailed ways

The embodiments of the present invention are described below by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

See Figures 1 to 5. It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings in this specification are only used to cooperate with the contents disclosed in the specification for the understanding and reading of those who are familiar with the technology, and are not intended to limit the implementation of the present invention. Restricted conditions, it does not have technical substantive significance, any structural modification, proportional relationship change or size adjustment, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the present invention. The scope of the disclosed technical content can be covered. At the same time, the terms such as "up", "down", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and clarity, and are not used to limit this specification. The implementable scope of the invention, and the change or adjustment of the relative relationship thereof, shall also be regarded as the implementable scope of the present invention without substantially changing the technical content.

The invention mainly relates to a hysteroscope. The core of this embodiment is an imaging module on the hysteroscope, which is placed at the front end of the intubation tube in the hysteroscope, carries a camera, etc., and is used to obtain images in the human body during diagnosis .

As shown in FIG. 1 to FIG. 5 , the imaging module of this embodiment includes:

A support base 1, the support base 1 has an instrument through-channel 2 and three installation grooves 12 disposed at the end of the support base and distributed in a circumferential direction, wherein the installation groove 12 in the middle has an inclined surface 11, the inclined surface 11 and the instrument The axis L of the through channel 2 is at an acute angle. For the convenience of description in this specification, the included angle between the inclined surface 11 and the axis L of the instrument through channel 2 is the angle a in FIG. 2 , which is an acute angle;

The camera 3 is arranged in the installation groove in the middle, and the camera is fixed on the inclined surface 11;

The LED light group 4 is placed in the other two installation slots.

In this embodiment, the axis L of the instrument through-channel 2 is collinear with the axis of the cannula assembly in the hysteroscope, which facilitates the insertion or withdrawal of the instrument. The camera 3 is fixed on the inclined surface 11. By setting the angle of the inclined surface 11, the camera is inclined downward to meet the needs of various viewing angles during diagnosis; This facilitates production and improves production efficiency.

In order to better install the above-mentioned LED lamp group 4, and to make the outer diameter of the support seat extremely small, as shown in FIG. The included angle is the angle b in Figure 5, which is an obtuse angle. Preferably, the included angle b is 150° to 180°. In this embodiment, the end face of the end of the support seat is an inclined surface 101, which increases the cross-section when the outer diameter of the support seat is the same, which can facilitate the installation of the LED light group, and further reduce the outer diameter of the support seat to 4.5 mm, or even below. If the inclined surface is inclined at an included angle of 150°, it can be achieved to increase the surface area of the mounting surface by as much as 16%, resulting in a support seat with a smaller diameter or larger inner diameter instrument through-channel, allowing for larger equipment or greater water flow.

In order to facilitate the installation of the above-mentioned camera, as shown in FIGS. 1 and 3 , in this embodiment, the installation groove 12 located in the middle has an opening opened in the circumferential direction of the support base 1, which can facilitate the camera to be directly snapped in through the opening. It is fixed to the above-mentioned inclined surface 11 . The camera 3 is clamped in the installation groove 12 in the middle, which is convenient for fixing; the fixing method of the camera is not limited to this, and it can also be fixed on the above-mentioned inclined surface by techniques such as glue.

In this embodiment, the device through-channel 2 is used as a water inlet and a device channel. In order to increase the water flow during subsequent use, the cross-section of the device through-channel 2 in this embodiment is elliptical. In order to prevent the camera from being affected and expand its field of view, the support base 1 in this embodiment is a transparent part.

In this embodiment, the cross-section of the device penetrating channel 2 can also be circular, and rigid, semi-rigid or flexible medical devices can be passed through it to facilitate diagnosis.

In this embodiment, the intubation tube of the hysteroscope includes an outer tube and an inner tube. The end of the inner tube is inserted into the instrument through channel 2, the outer tube is fixed to the support seat, and there is a water outlet channel between the outer tube and the inner tube. There can be a wire slot in the outer tube to allow the wires from the camera and LED assembly to pass through.

Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

The above-mentioned embodiments merely illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Anyone skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed in the present invention should still be covered by the claims of the present invention.
