As shown in FIG. 3, the stopper has a narrow mouth portion 142 near the side of the outer layer tube 100 (refer to FIG. 1), and the radial length D is blocked. The stop member 140 is gradually increased away from the distal end 100b direction, and the stopper member 140 forms a wide mouth portion 144 away from one side of the distal end 100b. In one embodiment, the wide mouth portion 144 may have a funnel shape; in various embodiments, the wide mouth portion 144 and the narrow mouth portion 142 may be two rings, respectively, which are connected by a strip. For example, one side of the wide mouth portion 144 can be pressed against a contact surface (eg, a skull surface), and a tubular body component that protrudes beyond the wide mouth portion is inserted into the cranial cavity. With this design, the stopper 140 receives a reaction force from the contact surface to support the tubular body assembly to control the penetration distance of the tubular body assembly and improve stability.

The distance between the end of the tubular body projecting from the distal end and the stop member can be adjusted. please Referring to FIG. 1 and FIG. 4, FIG. 4 is a schematic diagram of an embodiment of the operation of the endoscope device 10 corresponding to FIG. 1. As shown in FIG. 1, the endoscopic device 10 includes a spring 190 disposed on the tubular body assembly 110 and located between the distal end 100b of the outer layer tube 100 and the stop member 140. As shown in FIG. 4, when the push handle 150 is moved toward the stopper 140 (in the direction of the arrow), and the stopper 140 is pressed against the skull (not shown), the stopper 140 reversely compresses the spring 190. And the length of the tubular body assembly 110 protruding beyond the wide mouth portion is increased. In this way, the distance between the end of the tube assembly and the affected part of the body can be fine-tuned.

FIG. 5A is a schematic view of another embodiment of the endoscope device 10 of the present invention. The difference from the previous embodiment is that the tubular body assembly 110 includes the intermediate tube 120 and the inner tube 130. As shown in FIG. 5A, the middle tube 120 is sleeved in the outer tube 100. The outer surface of the middle tube 120 is threaded and screwed to the outer tube 100 (refer to FIG. 5B); however, in different embodiments, the intermediate tube 120 and the outer tube 100 may be designed to achieve relative expansion or contraction by other mechanisms. The effect of the move. The inner tube 130 is partially sleeved in the middle tube 120. The inner tube 120 has a contact end 132 that projects beyond the distal end 100b. The stopper 140 is sleeved outside the inner tube 130, and the stopper 140 is moved between the distal end and the contact end with respect to the middle tube 120. As shown in FIG. 5A, the endoscope device 10 includes a spring 190 disposed between the intermediate tube 120 and the stop member 140.

Further, as previously described, the endoscope device can be provided with a flushing tube, a photographing unit and a light source in the tubular body assembly as shown in Fig. 2A. For example, the flushing tube is sleeved in the inner tube, and the flushing tube extends along the inner tube into the cavity in the grip to receive the flushing material or to be connected to an external extractor. The photographing unit and the light source may be disposed in the inner tube and close to the contact end to observe the scene in the body. In one embodiment, the flushing tube is plastic, and the inner tube is made of metal, and the inner tube of the metal material guides the punching tube through a hard surface, such as a skull.

5B and 5C are schematic views of another embodiment of the operation of the endoscope device 10. As shown in Figures 5A and 5B, the intermediate tube 120 can protrude from the distal end 100b and move relative to the outer tube 100 in an extended position and a retracted position. In other words, in the embodiment of FIGS. 5A-5C, the tubular body assembly comprised of the intermediate tube 120 and the inner tube 130 is movable relative to the outer tube 100. As shown in Figure 5A, the intermediate tube 120 is in a retracted position. As shown in FIG. 5B, the middle tube 120 is moved toward the extended position (in the direction of the arrow), and the spring 190 is driven by the middle tube 120 to push the stopper 140 away from the distal end 100b, and the contact end 132 is far away. The length of the end 100b is increased. Thereby, the length from the contact end 132 to the distal end 100b of the inner tube 130 can be adjusted as the middle tube 120 is driven.

As shown in FIG. 5C, when the push handle 150 is moved toward the stopper 140 (in the direction of the arrow), and the stopper 140 is pressed against the skull (not shown), the stopper 140 reversely compresses the spring 190. The distance from the contact end 132 to the wide mouth portion increases. In this way, the distance between the contact end and the affected part of the body can be finely adjusted. With this design, when the grip is pushed, the stopper can be used for fixing, thereby reducing the influence of the user's hand shaking and improving the operation accuracy.

6A and 6B are schematic views showing an embodiment of the endoscope device 10 having button control. As shown in FIG. 6A, the inner tube 130 has a bendable portion 134 at a position closer to the contact end 132 than the stop member 140. Specifically, the outer surface of the inner tube 130 is formed with a plurality of slits 136 at the position of the bendable portion 134 to make it more flexible. The handle 150 is provided with a button 170 and a rocker 180. The button 170 controls the movement of the straw relative to the inner tube 130. For example, the portion of the suction tube that extends into the grip is coupled to the drive and the button is electrically coupled to the drive. When the button is depressed, the drive is actuated to extend the suction tube. As shown in FIG. 6B, when the button 170 is pressed, the suction pipe 160 protrudes outside the inner tube 130. In other words, the length of the suction tube 160 protruding from the contact end 132 to the nozzle of the inner tube 130 is adjustable. Thereby, the relative distance between the nozzle tube and other components in the inner tube (for example, the photographing unit) can be adjusted after the inner tube is inserted into the body to provide convenience for use.

Figure 7 is a schematic illustration of one embodiment of the bending of the inner tube 130. The rocking rod can be used to control the swing of the inner tube. As shown in Fig. 7, the inner tube 130 is biased from the original position (shown by the dotted line). One side of the axial direction A of the inner tube 130 is curved. Thereby, the rocker can control the inner tube to bend from the bendable portion, for example, swing up and down to the left and right to increase the field of view of the photographing unit. By this design, for example, when approaching the vicinity of the affected part, the stopper can be used to control the extension of the tube body, and the rocker can be oscillated with the rocker for observation, thereby avoiding omission of inspection and improving accuracy.

FIG. 8 is a schematic view of another embodiment of the endoscope device 10 of the present invention. As shown in FIG. 8, the stopper 140 has a sleeve 141 near one end of the outer tube 100. One end of the spring 190 abuts against the sleeve 141, and the other end of the spring 190 abuts the intermediate tube 120. In the embodiment of FIG. 8, the sleeve 141 is a part of the stopper 140 as an extension of the narrow mouth portion and provides a sufficient grip area when the user touches the stopper 140, and also avoids direct use by the user. Touching the inner tube 130 affects the operation process. In other embodiments, the sleeve 141 can be used as a separate component and assembled to the stop 140.

FIG. 9A is an enlarged view of one embodiment of the sleeve 141. As shown in FIG. 9A, the first guide groove 143 is formed on the side of the sleeve 141 facing away from the contact end as viewed from the distal end side. In addition, as shown in FIG. 9B, a partial enlarged view of the intermediate tube 120 is formed, and the middle tube 120 forms a second guiding groove 123 (on the side of the intermediate tube facing the contact end). The first guiding groove 143 is disposed opposite to the second guiding groove 123. The two ends of the spring 190 are respectively accommodated in the first guiding groove 143 and the second guiding groove 123. For example, one end of the spring 190 abuts against the surface 143a in the first guide groove 143, and the other end of the spring 190 abuts the surface 123a in the intermediate tube 120.

FIG. 10 is a perspective view of one embodiment of the stop member 140. As shown in FIG. 10, the stop member 140 has a web 146 and an outer rim 148. The radial length of the stop member 140 increases with away from one side of the sleeve, forming an outer edge on one side away from the sleeve. For example, the stop member can be pressed against a contact surface (eg, a skull surface) by an outer edge, and an inner tube system protruding beyond the outer edge can be inserted into the skull. By this design, the user can provide additional visual field. For example, when the front end of the tube body is aligned with the wound surface, the front side of the tube body can be observed from the gap between the strips, thereby increasing the convenience of operation.

FIG. 11 is a schematic diagram of an embodiment of the operation of the endoscope device 10 corresponding to FIG. 8. As shown in Fig. 11, when the push grip 150 is moved toward the stopper 140 (in the direction of the arrow), the stopper 140 abuts against one end (the position of the outer edge) of the sleeve 141 and presses contact with, for example, the skull. On the face (not shown), the sleeve 141 now compresses the spring 190 against the intermediate tube 120, and the distance from the contact end 132 to the stop 140 increases. In this way, the distance between the contact end and the affected part of the body can be finely adjusted. With this design, when the grip is pushed, the stopper can be used for fixing, thereby reducing the influence of the user's hand shaking and improving the operation accuracy.

The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the invention.
