Technical Field

The invention relates to the technical field of endoscope cold light sources, in particular to a medical endoscope cold light source lighting module.

Background

The medical endoscope is composed of an illumination light source and an imaging system, wherein the illumination light source is one of important components of the endoscope system, is mainly used for providing illumination required by the endoscope imaging system in a minimally invasive surgery in cooperation with the endoscope imaging system, and mainly comprises the following components: power module, main control board, adjust luminance panel, lighting chip and leaded light bundle interface. The light guide beam interface is a connecting port of the lighting chip and the light guide beam of the endoscope, is one of main user interfaces of the cold light source of the endoscope, and is the interface with the highest use frequency of the medical cold light source in the clinical use process.

However, different manufacturers in the market all have their own internally defined light guide beam interface forms, and with the increase in market share of mainstream manufacturers, four mainstream light guide beam interfaces exist in the market at present. The current medical light source lighting module can be divided into two types according to whether the light beam socket can be compatible with various light beam interfaces, wherein one type can be compatible with various light beam interfaces, and the other type cannot be compatible with various light beam interfaces.

The defect of the lighting module which can not be compatible with various light guide beam interfaces is obvious, if the equipment does not have the light guide beam interface which can be compatible with various light guide beams, the light guide beams and the equipment need to be in one-to-one correspondence in the clinical use process, so that the light guide beams can not be used universally on the equipment, and the high requirement is provided for the management of medical equipment; simultaneously, in clinical operation scene, every operation all can use the leaded light bundle interface, because equipment in the hospital at present all is provided by a plurality of producers, the specification of the leaded light bundle that so used is not necessarily the same, if the leaded light bundle interface can't accomplish compatible multiple leaded light bundle, will cause very big inconvenience to user's clinical use.

The lighting module that can compatible multiple leaded light beam interface on the existing market, its major disadvantage lies in, need the operation of user's both hands just can carry out the plug of leaded light beam, and partial scheme still need screw the screw and lock the leaded light beam, has promoted user's the use degree of difficulty, and the work scene of medical cold light source is in the marginal area of operating room aseptic zone, if its design is unreasonable, probably leads to the doctor to cross infect the patient with the bacterium in the use, causes very big risk to the operation. Meanwhile, because the mechanical structure compatible with various light guide beams is compact, and in order to improve the light flux, the light transmission element of the light source needs to be tightly attached to the end face of the light guide beam, and the existing scheme adopts a structure that the end face of the light guide beam and the end face of the light rod are closed, the light guide beam is easily overheated, and the light guide beam is easily scalded when being pulled out.

Meanwhile, in the current market, part of the prior art schemes are designed by adopting a scheme of a light guide beam socket compatible with various light guide beam interfaces and a light emitting element independent module at the rear end, and the scheme has the advantages that a user can conveniently switch the light guide beam interfaces, but the defect that the transmission efficiency of light is influenced, namely, the light source light emitting element and the light transmission element have axial eccentricity and axial distance deviation. The early xenon lamp proposal adopts the principle of concave mirror light condensation, and the light condensation surface is larger, so the influence of the optical axis eccentricity and the axial distance deviation of components on a light source light path on the light flux is smaller, while the light emitting surface of the LED proposal which is widely adopted at present is small, so the influence of the position precision of the components on the light path on the light flux is larger.

Meanwhile, the lighting module which is partially compatible with various light guide beam interfaces in the market at present also has the problem of light leakage, namely, the light emitted by the module in the light-emitting element can be seen from other holes except the main light through hole, the light leakage problem not only can affect the attractiveness, but also can affect the operation of a doctor if the light leakage is too serious, and therefore, the defect is unacceptable for users.

Still some producers in the market adopt to satisfy the scheme of compatible multiple leaded light beam through the user changes the leaded light beam socket temporarily, and this scheme is accomplished compatible multiple leaded light beam though also can, but has the inconvenient problem of operation and management: because of the existence of a plurality of light guide beam sockets, the light guide beam sockets are easy to lose in the storage process and can be replaced by special tools.
