Description

endoscopy

The present invention relates to endoscopes; in particular, it refers to an endoscope with a bendable tube for the user to hold.

Endoscopy is a technology developed mainly to enable people to observe the environment that is not easy to enter. It is mainly used in medical equipment, and enters the human body through various pipes to detect the internal conditions of the human body. The function of endoscopy is to reduce the discomfort of patients and reduce the size of the wound to complete the diagnosis of the affected part in the body. Therefore, it is widely used in various medical examinations, such as the diagnosis and treatment of the cranial cavity, stomach, chest, spine, brain and other parts.

Known endoscopes generally include a detection catheter and a handle that are connected to each other. After medical personnel hold the handle and insert the detection catheter into the human body, the image inside the human body is obtained by the lighting unit, and then the image is transmitted from the image transmission unit to the outside. , to assist medical personnel in diagnosing affected parts of the body.

An inflexible hard tube is usually set at the connection between the detection tube and the handle of the endoscope. When the connection between the detection tube and the handle is an inflexible tube, the handle cannot be bent relative to the detection tube. The placement position of the handle will be restricted by the placement of the detection catheter and cannot be placed in a suitable position arbitrarily, so that when medical personnel perform surgery, the surgical operation space is limited. The gestures or physical conditions of the personnel are not necessarily the same. When the handle cannot be bent relative to the detection catheter, it is easy to cause operation. Medical personnel performing endoscopy feel uncomfortable or uncomfortable. Therefore, the conventional endoscope still needs to be improved.

In view of this, the purpose of the present invention is to provide an endoscope with a bendable tube for the user to hold. When the user operates the endoscope, the endoscope can be changed by bending the bendable tube. The relative position of the handle and the detection part can achieve the purpose that the user can arrange the position of the handle according to the needs, thereby improving the operation space when the conventional endoscope is used for surgery, which is limited and cannot meet the operation of each user. a question of habit.

In order to achieve the above object, the present invention provides an endoscope for detecting an object to be detected, comprising a detection part, an operation part and an image optical fiber, the detection part is used to enter the interior of the object to be detected, and the detection part It includes a conduit; the operation part is arranged outside the object to be detected for the user to hold, the operation part includes a handle and a bendable tube, and the bendable tube is respectively connected to the handle at opposite ends and the conduit, the tube section of the bendable tube can maintain a bent state after being bent by an external force; the imaging optical fiber is used for outputting light and transmitting images, and passes through the bendable tube and the conduit.

The effect of the present invention is that when the user operates the endoscope, the user can hold the handle or the bendable tube and send the detection portion into the object to be detected, and bend the bendable tube as required, Then, the handle is moved to an appropriate position relative to the detection part, so as to meet the operation requirements of users with different physical conditions. Besides, when the handle or the bendable tube is located at a position that will affect the operation At the same time, the user can also move the handle to an appropriate position relative to the detection portion by bending the bendable tube, thereby making the arrangement of the surgical operation space more flexible.

5 is a perspective view of an endoscope according to another preferred embodiment of the present invention.

In order to describe the present invention more clearly, preferred embodiments are given and described in detail with the drawings as follows. Referring to FIGS. 1 to 4 , an endoscope 1 according to a preferred embodiment of the present invention is used to detect an object S to be detected. The endoscope 1 includes a detection part 10 , an operation part 20 and a The imaging optical fiber 30, the detection part 10 is for entering the inside of the object to be detected S, the operation part 20 is arranged outside the object to be detected S for the user to hold, the detection part 10 includes a catheter 12, the operation part 20 includes A handle 22 and a bendable tube 24, the bendable tube 24 is respectively connected to the handle 22 and the conduit 12 at opposite ends. Under the condition of sufficient external force, as shown in FIG. 4, the pipe section of the bendable tube 24 can maintain a bent state; the imaging optical fiber 30 is used for outputting light and transmitting images, and passes through the bendable tube 24 and the conduit 12.

Thereby, when the user operates the endoscope, the user can hold the handle 22 or the bendable tube 24 and send the detection portion 10 into the object S to be detected, and bend it as needed as shown in FIG. 4 . The bendable tube 24 enables the handle to move to an appropriate position relative to the detection portion 10 without affecting the setting position of the detection portion 10 to meet the operational needs of users with different physical conditions. In addition, when the handle 22 or the bendable tube 24 is located in a position that will affect the operation When in position, the user can also move the handle 22 to an appropriate position relative to the detection portion 10 by bending the bendable tube 24 , thereby making the arrangement of the surgical operation space more flexible.

The endoscope 1 includes a connector 40 , two ends of the connector 40 are respectively connected to the catheter 12 and the bendable tube 24 , whereby the imaging optical fiber 30 can pass through the bendable tube 24 , the connection Among the components 40 and the conduit 12, in this embodiment, the connecting piece 40 is connected with the bendable tube 24 and the conduit 12 in a non-detachable manner. In other embodiments, the connecting piece 40 is not excluded. It is detachably connected to at least one of the bendable tube 24 and the conduit 12 .

Please refer to FIG. 3, wherein the wall of the bendable tube 24 includes an outer layer 24a and an inner layer 24b, wherein the outer layer 24a includes polyvinyl chloride or polysiloxane material, and the inner layer 24b includes metal material, wherein the The metal material can be, for example, medical grade stainless steel, but not limited thereto.
