The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

The invention is further described with reference to the following figures and specific embodiments.

Example 1:

the present embodiment provides a handheld end of an endoscope, as shown in fig. 1 to 6, including a housing 1, an insertion tube 2, and a signal wire 3; the insertion tube 2 and the signal wire 3 are respectively arranged at two ends of the shell 1; be provided with controller 4 in the shell 1, the one end that shell 1 was kept away from to intubate 2 is provided with light source subassembly 5 and camera 6, and light source subassembly 5 and camera 6 all are connected with controller 4 electricity, and controller 4, light source subassembly 5 and camera 6 all are connected with signal line 3 electricity.

It should be understood that, as shown in fig. 5, the end of the insertion tube 2 remote from the housing 1 seals the light source assembly 5 and the camera head 6 by the transparent cover 14, and the controller 4, the light source assembly 5 and the camera head 6 can be electrically connected with the upper computer of the endoscope and the external power supply through the signal wires 3.

This embodiment is in the implementation, and when can avoiding inserting the intubate 2 into patient internally, the problem of signal line 3 contact patient, user experience is good, can realize aseptic technique simultaneously. Particularly, this embodiment is at implementation in-process, and the intubate 2 is internal to insert patient, and light source subassembly 5 and camera 6 on the intubate 2 are opened, and light source subassembly 5 is used for providing the illumination, and camera 6 can record the video signal of the internal organ state of patient, then sends video signal to controller 4 in, controller 4 handles video signal and sends video signal to display equipment such as host computer through signal line 3. Insert patient internal back with intubate 2, medical personnel can hand

shell

1, and 3 orientation of signal line extend the setting towards the direction of keeping away from patient this moment, so can effectively avoid 3 contact patient of signal line, and user experience is better, can avoid patient to receive the infection simultaneously, realized aseptic technique.

In the invention, the handheld end of the endoscope also comprises a catheter 7 and a suction tube 8; an instrument channel 15 is formed in the insertion tube 2 along the axial direction of the insertion tube 2, one end of the insertion tube 2 close to the shell 1 is communicated with one end of the suction tube 8 through the catheter 7, and the other end of the suction tube 8 far away from the catheter 7 extends out of the shell 1. It should be noted that, in the implementation process, the medical staff can sequentially pass through the suction tube 8, the catheter 7 and the insertion tube 2 to suck out the secretion in the patient body, so as to avoid the problem that the secretion shields the camera, and to make the shooting effect of the camera better.

It should be noted that the suction tube 8 in the prior art is usually disposed at the side of the housing 1, and the general medical staff can only operate with the right hand to suck the secretion in the patient body contacted with the end of the insertion tube 2 far away from the housing 1 through the catheter 7 and the suction tube 8 in sequence, which is inconvenient for the medical staff to use when the medical staff is used to operate with the left hand, such as left-handed person. In this embodiment, in order to avoid the above-mentioned problem among the prior art, attract pipe 8 to set up the one end at signal line 3 place on shell 1 to attract pipe 8 to keep away from the one end of pipe 7 and extend the setting towards the one end of keeping away from signal line 3, so can make the medical personnel of different operation habits all can conveniently attract the internal secretion of patient, the user operation of being convenient for.

Specifically, as shown in fig. 7, the suction tube 8 includes a guide tube 801 and a limiting tube 802, the guide tube 801 is arranged to communicate with the catheter 7, and the limiting tube 802 is arranged to communicate with one end of the guide tube 801 far away from the catheter 7; the outer diameter of the limiting pipe 802 is gradually reduced from one end close to the guide pipe 801 to one end far away from the guide pipe 801; the limiting pipe 802 is fixedly sleeved with a limiting ring 803. In this embodiment, the guiding rod 801 is bent to achieve the guiding of the secretion output. In the using process, a drainage pipeline can be sleeved on the limiting pipe 801 to realize drainage of secretions, the drainage pipe is generally set to be a hose, the drainage pipe can be sleeved on the limiting pipe 801 in the process of fixing the drainage pipe and the limiting pipe 801, then the drainage pipe is in interference fit with the limiting ring 803, and therefore the drainage pipe and the limiting pipe are tightly connected.

In this embodiment, the limiting tube 802 is further fixedly sleeved with a leather cup 804, and the leather cup 804 is located on one side of the limiting ring 803 far away from the guide tube 801; the outer end of the leather cup 804 extends towards the side where the limiting ring 803 is located. It should be noted that when the drainage tube slides towards the direction away from the limiting tube 801, the leather cup 804 bends, and the friction force between the leather cup and the inner wall of the drainage tube is large, so that the problem of slippage of the drainage tube is avoided.

The number of the cups 804 is multiple, and the outer diameters of the cups 804 gradually decrease from one end close to the guide pipe 801 to one end far away from the guide pipe 801. Therefore, in the process of slipping the drainage tube, the contact area between the drainage tube and the leather cup 804 is increased, and the friction force between the leather cup 804 and the drainage tube is enhanced.

In this embodiment, the housing 1 is provided in an arc shape along the end where the insertion tube 2 is located toward the end where the signal line 3 is located. Thus, the problem of the conduit 7 breaking caused by the excessive bending of the conduit 7 can be avoided.

In this embodiment, be provided with baffle 9 in the shell 1, baffle 9 is provided with two, and two baffles 9 all set up along the axial extension of pipe 7, constitute the pipe holding tank between two baffles 9.

In this embodiment, the handheld end of the endoscope further comprises an instrument tube 10, and the instrument tube 10 is arranged to communicate with the guide tube 7; the instrument tube 10 is arranged in the middle of the housing 1, the end of the instrument tube 10 away from the guide tube 7 is arranged to extend out of the housing 1, and the perspective structure of the instrument tube 10 is shown in fig. 8. It should be noted that the instrument tube 10 of the prior art is usually disposed on the top of the housing 1, so that the doctor may hit the instrument on his face when operating the instrument, which is inconvenient. In order to avoid the above problems, in the present embodiment, the instrument tube 10 is located at the bottom of the casing 1 near the insertion tube 2, so as to facilitate the operation of the instrument by the doctor, and meanwhile, since the casing 1 is set to be arc-shaped, the problem that the catheter 7 or the insertion tube 2 is broken during the process of inserting the instrument into the insertion tube 2 sequentially through the instrument tube 10 and the catheter 7 can be avoided.

In this embodiment, the handheld end of the endoscope further includes a suction pump 11, the suction pump 11 is disposed in communication with the catheter 7, and a perspective view of the suction pump 11 is shown in fig. 9. It should be noted that the suction pump 11 is used for pumping the secretion at the end of the insertion tube 2 into the suction tube 8 sequentially through the insertion tube 2 and the catheter 7, so that the medical staff can suck the secretion in the patient.

In this embodiment, the suction tube 8, the instrument tube 10, and the suction pump 11 are all fixedly provided with a limiting rod 12, the inner wall of the housing 1 cooperates with the limiting rod 12 to form a limiting groove 13, and the limiting rod 12 is in interference fit with the limiting groove 13. The interference fit prevents the stop rod 12 from easily sliding out of the stop slot 13.
