Endoscope system convenient for gas injection

Abstract

An endoscope system facilitating gas injection relates to the field of endoscopes and comprises an endoscope body, a gas inlet connector is mounted at a gas inlet in the bottom end of the right side area of the endoscope body, and a pressure discharge pipe is fixedly connected to the position, on the upper side of the gas inlet connector, of the endoscope body. An inner cavity of the pressure discharging pipe is communicated with an inner cavity of the air inlet connector in the endoscope body, a pressure discharging threaded column is in threaded connection with the interior of the inner cavity of the pressure discharging pipe, and an exhaust cavity penetrating up and down is formed in the pressure discharging threaded column. Once the air pressure is too high, most of the air pressure can be deflated to reduce the air pressure intensity, so that protection is formed to effectively prevent a patient from feeling uncomfortable due to too high air pressure during air injection, and meanwhile, a pressure discharge threaded column can be rotated to control the length of the pressure discharge threaded column extending into an inner cavity of a pressure discharge pipe, so that the pressure discharge pipe is convenient to use. And therefore, the protection range of the injected gas pressure can be adjusted, and the gas injection control of a doctor on different parts is greatly facilitated.

Description

Technical Field

[0001] The utility model relates to the field of endoscopes, in particular to an endoscope system which is convenient for gas injection. Background Art

[0002] During endoscopy or surgery, gas (usually carbon dioxide) is injected into the patient's body to create a working space so that the doctor can see the inside of the organ more clearly through the endoscope and perform operations. This process is called pneumoperitoneum (for laparoscopic surgery) or insufflation (for other endoscopic procedures such as colonoscopy);

[0003] During this process, strict attention must be paid to the gas injection pressure, and the pressure required in different areas of the patient's body is different. Once the pressure is too high, the patient will feel very uncomfortable. Utility Model Content

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] See also Figure 1-5 The utility model provides an embodiment: an endoscope system for convenient gas injection, comprising an endoscope body 10, an insertion part 11 installed at the left end of the endoscope body 10, a handle part 12 fixedly installed on the endoscope body 10, a control button provided on the handle part 12, and a gas injection access area provided in the right area of ​​the endoscope body 10, wherein an air inlet interface 14 is installed at the air inlet at the bottom end, a pressure relief pipe 15 is fixedly connected to the upper side of the air inlet interface 14 on the endoscope body 10, and the inner cavity of the pressure relief pipe 15 and the inner cavity of the air inlet interface 14 are connected to each other in the endoscope body 10. The main body 10 is connected, and a pressure-relief threaded column 16 is threadedly connected in the inner cavity of the pressure-relief pipe 15, so that the position of the pressure-relief threaded column 16 in the inner cavity of the pressure-relief pipe 15 can be adjusted, and an inner recess 20 is provided at the bottom position of the exhaust cavity 19 in the pressure-relief threaded column 16, and air holes 21 are provided in the inner recess 20, and air holes 21 are equidistantly distributed on the side walls of the air holes 21, and the air holes 21 are connected to the exhaust cavity 19, and an air plug plate 23 is slidably installed in the inner recess 22, and a spring is connected between the air plug plate 23 and the top of the inner recess 22.

[0025] When the endoscope is used and gas needs to be injected, the handle 12 is held by hand for operation, and the gas inlet interface 14 at the bottom is connected to the gas outlet pipe 13 of the gas injection device, and the gas enters the gas inlet interface 14 from the gas outlet pipe 13 of the gas injection device, and enters the inner cavity of the pressure relief pipe 15 at the same time. When gas injection starts, the corresponding control button is pressed to inject gas. Once the gas pressure entering from the gas inlet interface 14 is too high, the gas will squeeze the gas plug plate 23 in the pressure relief pipe 15, thereby pushing the gas plug plate 23 upward, so that the gas plug The plate 23 slides to the air hole 21, exposing the air hole 21 so that the exhaust cavity 19 is connected with the inner cavity of the pressure relief tube 15, thereby partially deflation to reduce the gas pressure, thereby forming a protective function that can effectively avoid excessive gas pressure during gas injection and cause the patient to feel uncomfortable. At the same time, the pressure relief threaded column 16 can be rotated to control the length of the pressure relief threaded column 16 extending into the inner cavity of the pressure relief tube 15, thereby adjusting the protection range of the injected gas pressure, which greatly facilitates the doctor's control of gas injection in different parts.

[0026] It should be noted that, in order to facilitate the doctor to adjust the position of the pressure-relief threaded column 16 , in the present embodiment, an exhaust cap 17 is fixedly connected to the top of the pressure-relief threaded column 16 , and openings 18 are distributed in the exhaust cap 17 .

[0027] In addition, in one embodiment, the air holes 21 can be arranged in a long strip shape, so that when the pressure is too high, the distance that the air block plate 23 is pushed upward will be greater, so that the exposed connecting part of the air holes 21 will become larger and larger, which can speed up the exhaust speed.

[0028] It is worth mentioning that, in this embodiment, the bottom end surface of the gas plug plate 23 can be set to be an arc-shaped concave shape, so that when the gas is pressed on the gas plug plate 23, the force can be concentrated in the middle area.

[0029] In specific implementation, when gas injection is required during use of the endoscope, the handle portion 12 is held by hand for operation, the insertion portion 11 is inserted, and the air inlet interface 14 at the bottom is connected to the air outlet pipe 13 of the air injection device. The gas enters the air inlet interface 14 from the air outlet pipe 13 of the air injection device, and simultaneously enters the inner cavity of the pressure relief pipe 15. When gas injection begins, the corresponding control button is pressed to inject gas. Once the gas pressure entering from the air inlet interface 14 is too high, the gas will squeeze the gas plug plate 23 in the pressure relief pipe 15, thereby pushing the gas plug plate 23 upward. The top of the air plug plate 23 makes the air plug plate 23 slide to the air hole 21, leaving the air hole 21 exposed so that the exhaust cavity 19 is connected with the inner cavity of the pressure relief pipe 15, thereby partially releasing the gas to reduce the gas pressure, thereby forming a protective function that can effectively avoid excessive gas pressure during gas injection and cause the patient to feel uncomfortable. At the same time, the pressure relief threaded column 16 can be rotated to control the length of the pressure relief threaded column 16 extending into the inner cavity of the pressure relief pipe 15, thereby adjusting the protection range of the injected gas pressure, which greatly facilitates the doctor's control of gas injection in different parts.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manner derived by those skilled in the art based on the technical solution of the present invention also falls within the scope of protection of the present invention.
