Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an electronic bronchoscope with a full-time oxygen supply function. Background Art

[0002] With the rapid development of science and medical technology, endoscopic minimally invasive or non-invasive medical examinations and treatments have become widely popular. Electronic bronchoscopes have become an important tool for the diagnosis and treatment of respiratory diseases. During the operation of an electronic bronchoscope, the insertion part will enter the bronchus through the mouth or nose. At this time, part of the space in the bronchus is occupied by the insertion part of the electronic bronchoscope, and the cross-sectional area of ​​the oxygen delivery channel is greatly reduced. In addition, during the operation, there is the possibility of negative pressure suction operation, which may cause the patient to experience symptoms of low blood oxygen content. Usually in this case, the electronic bronchoscope needs to be removed from the patient's body, and then oxygen is supplied to the patient. After the patient's blood oxygen content returns to normal levels, the bronchoscope is inserted again for operation. This reciprocating cycle will greatly increase the operation time and make the operation more difficult.

[0003] Chinese utility model patent CN215651007U (authorization announcement date 2022.01.28) discloses a multifunctional bronchoscope, comprising an operating part, an insertion part, a bending part and a tip part with a camera and a light source connected in sequence. The tip part is a telescopic design, and the telescopic part is a cone with a diameter gradually decreasing toward the tip. The end of the cone is the opening of the working channel. The working channel can be switched at any time to connect with external oxygen supply equipment, negative pressure device and thermocoagulation probe through several external interfaces located on the operating part. The above patent uses a working channel for oxygen supply, which can alleviate the problem of hypoxia to a certain extent. However, because the working channel takes into account the functions of negative pressure suction and instrument passage, oxygen cannot be supplied during negative pressure suction or instrument passage. Patients usually experience hypoxia during negative pressure suction, so the hypoxia problem cannot be solved well.

[0004] Another method is to add an independent oxygen supply tube in the insertion part, which will further increase the outer diameter of the insertion part and is not applicable in actual application requirements that require the outer diameter of the insertion part to be as small as possible.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] An electronic bronchoscope with full-time oxygen supply function, such as Figure 1-Figure 7 As shown, the device comprises an insertion portion 1 and a handle 2. The distal end of the insertion portion 1 is fixedly provided with a head end seat 101, and the proximal end is connected to the handle 2. The head end seat 101 is provided with a module 102, and a module line 1021 of the module 102 extends axially toward the proximal end of the insertion portion. A clamp channel 108 is provided within the insertion portion, with the distal end of the clamp channel 108 fixedly connected to the head end seat 101 and the proximal end extending axially toward the proximal end of the insertion portion. The space between the inner wall of the insertion portion and the outer walls of the clamp channel 108 and the outer walls of the module line 1021 forms an insertion portion oxygen supply channel. The outer wall of the insertion portion is provided with at least one oxygen supply hole 111 connected to the insertion portion oxygen supply channel. The insertion portion oxygen supply channel is connected to the handle 2, and the handle 2 is provided with an oxygen supply interface 25 for connecting to an oxygen source. Oxygen enters the handle 2 through the oxygen supply interface 25, is transported through the insertion portion oxygen supply channel to the distal end of the insertion portion, and is then delivered to the bronchi through the oxygen supply hole 111.

[0032] Furthermore, the handle 2 is provided with a Y-shaped connector 23. The Y-shaped connector 23 includes a first branch 231 and a second branch 232. The first branch 231 and the second branch 232 are interconnected. The first end 2311 of the first branch 231 is sealed and fixedly connected to the outer side of the proximal end of the insertion portion. The second end 2312 of the first branch 231 extends out of the insertion portion and is sleeved on the outside of the clamp channel tube 108 and the module line 1021. At the connection point, it is sealed and fixedly connected to the clamp channel tube 108 and the module line 1021. The second branch 232 is connected to the oxygen supply interface 25 via the connecting pipe 24. Preferably, the end of the second branch 232 is provided with a pagoda interface 2321 for sealing and fixed connection with the connecting pipe 24. Preferably, the oxygen supply interface 25 is connected to a speed regulating valve 26. One end of the oxygen supply interface 25 is provided with a channel 253 that is sealedly connected to the connecting pipe 24, and the other end is provided with a pipe threaded hole 251 that is sealedly connected to the speed regulating valve 26. A boss 252 is provided on one side of the pipe threaded hole 251. The speed regulating valve 26 is equipped with an air inlet 263, an adjustment knob 261, and a gear scale 262. The adjustment knob can be used to adjust the gear to control the oxygen supply speed. The oxygen source is directly connected to the air inlet of the speed regulating valve, without passing through any valve body or equipment that can reduce the oxygen supply flow, to avoid insufficient oxygen supply after multiple speed adjustments.

[0033] Furthermore, the insertion part 1 includes an insertion tube 105 and a snake tube 103. The distal end of the insertion tube 105 is connected to the snake tube 103. A rubber tube 104 is sleeved on the outer periphery of the snake tube 103. The head end seat 101 is fixed at the distal end of the snake tube 103. The distal end of the snake tube 103 is fixedly connected to a steel wire rope 107. The steel wire rope 107 extends toward the proximal end of the insertion part. The proximal end of the snake tube 103 is fixedly connected to a spring tube 106. The spring tube 106 extends axially toward the proximal end of the insertion part. A section of the steel wire rope 107 located in the insertion tube 105 is passed through the spring tube 106.

[0034] A cross section is made at the insertion tube 105 along a plane perpendicular to the axis of the insertion portion 1. Figure 6 As shown, the insertion tube 105 contains the clamp channel tube 108, the spring tube 106 and the module line 1021. The space between the inner wall of the insertion tube 105 and the outer walls of the clamp channel tube 108, the spring tube 106 and the module line 1021 constitutes the first oxygen supply channel 109. Similarly, a cross-section is made at the snake tube 103 along a plane perpendicular to the axis of the insertion portion. Figure 7 As shown, the serpentine tube 103 accommodates the clamp channel tube 108 and the module line 1021. The space between the inner wall of the serpentine tube 103 and the outer walls of the clamp channel tube 108 and the outer walls of the module line 1021 constitutes the second oxygen supply channel 110. The first oxygen supply channel 109 and the second oxygen supply channel 110 are interconnected at the connection position between the serpentine 103 and the insertion tube 105, together forming a complete insertion oxygen supply channel.

[0035] The oxygen supply hole 111 can be placed on the insertion tube 105 and / or the rubber tube 104 and / or the head end seat 101. The shape, number, arrangement and spacing of the oxygen supply holes 111 can be set according to actual needs. Preferably, when the number of the oxygen supply holes is greater than 1, the oxygen supply holes are arranged in a straight line, a ring or a spiral around the insertion part. When the oxygen supply hole 111 is set on the insertion tube 105, the setting position avoids the parts in the insertion tube 105 from covering the oxygen supply hole 111. When the oxygen supply hole 111 is set on the rubber tube 104, the setting position avoids the position where the rubber tube and the snake tube are in contact. When the oxygen supply hole 111 is set on the head end seat 101, the setting position avoids the parts installed on the head end. Ensure that the oxygen supply channel of the insertion part can be connected to the outside without obstruction.

[0036] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
