The following description is presented to disclose the invention to enable those skilled in the art to practice the invention.

The preferred embodiments in the following description are by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention as defined in the following description may be applied to other embodiments, modifications, improvements, equivalents, and other embodiments without departing from the spirit and scope of the invention.

As shown in FIG. 1 to FIG. 5, an endoscope apparatus and a medical operation method according to a preferred embodiment of the present invention are used for clearly obtaining the inside of a patient's body during medical treatment by a medical professional. The image, and at the same time, can be directly treated, sampled or examined according to the needs of the treatment. It is worth mentioning that the endoscope device of the present invention can ensure clear output of the internal image if the endoscope device is attached to an object in the patient during use.

According to a preferred embodiment of the present invention, the endoscopic device is operatively coupled to a host computer via a transmission unit to obtain relevant data while performing medical activities, and at the same time, medical treatment is possible. The endoscope device includes a first catheter 10, a camera assembly 20, an adapter unit 30, and a handle member 40. The first passage 10 extends through the grip member 40. The camera assembly 20 is disposed at a front end of the first duct 10. The switching unit 30 is electrically connected to the camera assembly 20 such that the internal image of the patient's body acquired by the camera assembly 20 is output to the upper computer via the switching unit 30. The handle member 40 can accommodate a portion of the first conduit 10 and the adapter unit 30. It is worth mentioning that the handle member 40 can be regarded as a grip portion that facilitates gripping and operation of the hand-held endoscope device.

As shown in FIGS. 1 to 4, the first catheter 10 has a receiving end 11 and an extracting end 12. The handle member 40 includes a first end surface 41 and a second end surface 42. The insertion end 11 of the first duct 10 extends from the first end face 41 of the grip member 40. The take-up end 12 of the first conduit 10 extends from the second end face 42 of the handle member 40. The camera assembly 20 is disposed adjacent to the insertion end 11 of the first conduit 10 such that when the first guide When the insertion end 11 of the tube 10 enters the patient's body, the camera set 20 can directly record the internal image of the patient's body and output to the upper computer via the switching unit 30. . Further, the first catheter 10 is provided with a rounded head end member 13 coupled to the insertion end portion 11 such that when the insertion end portion 11 of the first catheter 10 enters the patient's body, The head end member 13 allows the first catheter 10 to enter the patient's body with less resistance, thus slowing the patient's discomfort.

It is worth mentioning that the first duct 10 has an opening 14 which is located on a side between the insertion end 11 and the head end member 13 through which the camera assembly 20 passes. An internal image of the patient is obtained, and the internal image is output to the upper computer via the switching unit 30. In particular, when the medical professional obtains an internal image, the desired medical behavior can be performed directly from the opening 14 of the first catheter 10, such as taking out foreign bodies in the body and collecting samples. It will be appreciated that the foreign body and sample in the body pass through the opening 14 through the first conduit 10 and are finally removed from the take-up end 12.

According to a preferred embodiment of the present invention, the first duct 10 of the endoscopic device has a first passage 15 inside, via the negative pressure principle, when the insertion end 11 of the first duct 10 enters the When the patient's body is described and the internal image is acquired via the camera assembly 20 and the adapter unit 30, the first catheter 10 draws the foreign body or the sample from the opening 14 by using the negative pressure principle. The foreign body or the sample in the body is discharged from the take-up end 12 via the first conduit 10. For example, when the insertion end 11 of the first catheter 10 enters the patient's body during abortion surgery, the embryo can be directly drawn from the first catheter 10 via a negative pressure to achieve a true Painless abortion surgery and provides a non-invasive treatment.

In addition, it is worth mentioning that the outer diameter of the first catheter 10 is designed to be within 5.5 millimeters (mm), that is, less than or equal to 5.5 millimeters (mm), so that the patient can be reduced when performing medical behavior. Discomfort and injury. In other words, such an improvement of the invention will result in said Endoscopic devices are more suitable for use in minimally invasive medicine. For example, in the case of human male urethra testing, a typical urethral endoscope is about 7 to 8 millimeters (mm) in diameter, which can cause pain and physical and mental harm to the patient during medical procedures. In contrast, the first catheter 10 of the endoscopic device of the present invention has a diameter within 5.5 millimeters (mm) to greatly reduce the damage to the patient. In addition, it is worth mentioning that the first catheter 10 can be made of stainless steel or various medical materials. In other words, the first conduit 10 can be a hollow stainless steel tube.

According to a preferred embodiment of the present invention, the camera assembly 20 includes a lens unit 21, a lighting unit 22, and a photosensitive unit 23. The lens unit 21 is directly disposed at the opening 14 facing the first duct 10, and the photosensitive unit 23 is disposed at the rear of the lens unit 21 such that the photosensitive unit 23 passes through the lens unit 21 After the internal image is directly obtained, the internal image is transmitted to the upper computer via the switching unit 30. The illumination unit 22 is located adjacent to the opening 14 of the first catheter 10 and adjacent to the lens unit 21 such that the illumination unit 22 can provide illumination to the brightness required for the medical action while being available A light source is given to the lens unit 21 such that the medical behavior is performed with sufficient brightness, and the lens unit 21 is capable of obtaining a clear internal image. It is straightforward that the lens unit 21 of the camera assembly 20 is photographed via VGA pixel color and provides an LED cold light source via the illumination unit 22 of the camera assembly 20, and thus, within the use When the speculum device performs an inspection or detection, the camera assembly 20 can limit the detection of foreign matter greater than 6 individual cells (ie, a diameter greater than 0.15 mm).
