Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a suction tube fixing device for a nasal endoscope. Background Technology
[0002] Nasal endoscopy plays an important role in the medical field, especially in otolaryngology. It is an endoscope that is inserted deep into the nasal cavity of a patient to observe the internal structure and lesions, allowing surgery or examination of the nasal cavity, sinuses, and especially deep parts to be performed under direct vision.
[0003] During nasal endoscopy for internal nasal observation and surgical treatment, a suction tube is usually used to remove excess fluid from the nasal cavity to keep the surgical or treatment area clean.
[0004] However, in actual use, doctors generally need to hold the nasal endoscope with one hand and the suction tube with the other to operate. During the operation, doctors also need to hold the surgical instruments. Therefore, doctors need to alternately pick up and put down the suction tube and surgical instruments, which seriously affects the efficiency of the operation. Therefore, there is an urgent need to provide a suction tube fixing device for nasal endoscopes that can fix the suction tube to the nasal endoscope, freeing up one of the doctor's hands and improving the efficiency of the operation. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a suction tube fixing device for a nasal endoscope, which can fix the suction tube to the nasal endoscope, freeing up one of the doctor's hands and improving surgical efficiency.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A suction tube fixing device for a nasal endoscope includes a nasal endoscope and a suction tube. The device also includes a main fixing post made of elastic material. The main fixing post has a first through hole and a second through hole that are parallel to each other. The first through hole and the second through hole both penetrate the front and rear ends of the main fixing post. The first through hole is press-fitted with the front end of the nasal endoscope, and the second through hole is press-fitted with the front end of the suction tube.
[0008] Furthermore, both ends of the first through hole are provided with nasal endoscope bypass fixing holes, and nasal endoscope auxiliary fixing posts are provided in the nasal endoscope bypass fixing holes, which are tightly fitted with the nasal endoscope.

[0011] Furthermore, one end of the suction tube auxiliary fixing post is also connected to the main fixing post via a connecting rope.
[0012] Furthermore, the main fixing column is also provided with a ramp surface and a water injection conduit. The ramp surface is located at the top of the main fixing column and above the first through hole, and is connected to the first through hole. The water injection conduit is connected to the outside of the main fixing column. One end of the water injection conduit is connected to the top of the ramp surface, and the other end is used to connect to the needle tube. The water injection conduit is provided with a water injection hole that cooperates with the needle tube.
[0013] Furthermore, the inclination angle of the slope is within the range of 30 degrees to 60 degrees.

[0018] (1) This utility model proposes to set two parallel through holes in the elastic main body fixing column, and fix the nasal endoscope and the suction tube by interference fit respectively, so that the nasal endoscope and the suction tube are fixed together and the ends are parallel to each other; it can also adjust the extension length of the nasal endoscope and the suction tube so that the suction tube is slightly longer than the tip of the nasal endoscope.
[0019] When using it, doctors can grasp the nasal endoscope and suction tube with one hand, freeing up the other hand to easily handle surgical instruments for surgical operations. The whole device is convenient and reliable to use, greatly improving the efficiency of doctors' work.
[0020] (2) In order to further stabilize and fix the nasal endoscope and suction tube, the present invention provides bypass fixing holes at the front and rear ends of the first through hole and the second through hole. By inserting an auxiliary fixing post into the bypass fixing hole, a tighter fit with the nasal endoscope and suction tube is achieved, making the main fixing post more stable and reliable in fixing the nasal endoscope and suction tube.
[0021] (3) By setting a sloping surface above the first through hole and connecting a water injection tube, water can be injected through a needle tube, so that the water flows through the water injection tube and the sloping surface into the end of the nasal endoscope to perform simple cleaning of the endoscope surface. This allows for quick cleaning of the nasal endoscope surface during surgery. The water generated during cleaning is sucked out by the suction tube, which will not wear the nasal endoscope surface and is convenient and quick to use. Attached Figure Description

[0032] Example 1
[0033] like Figures 1-3 As shown, this embodiment provides a suction tube fixing device for a nasal endoscope, including a nasal endoscope 1 and a suction tube 2. The device also includes a main fixing post 3, which is made of elastic material. The main fixing post 3 has a first through hole 301 and a second through hole 302 that are parallel to each other. The first through hole 301 and the second through hole 302 both pass through the front and rear ends of the main fixing post 3. The first through hole 301 is press-fitted with the front end of the nasal endoscope 1, and the second through hole 302 is press-fitted with the front end of the suction tube 2.
[0034] This utility model proposes to set two parallel through holes in the elastic main body fixing column 3, and fix the nasal endoscope 1 and the suction tube 2 by interference fit, so that the nasal endoscope 1 and the suction tube 2 are fixed together and the ends are parallel to each other; it can also adjust the extension length of the nasal endoscope 1 and the suction tube 2, so that the suction tube 2 is slightly longer than the tip of the nasal endoscope 1.

[0040] To further stabilize and fix the nasal endoscope 1 and the suction tube 2, this solution provides bypass fixing holes at the front and rear ends of the first through hole 301 and the second through hole 302. By inserting an auxiliary fixing post into the bypass fixing hole, a tighter fit with the nasal endoscope 1 and the suction tube 2 is achieved, making the fixation of the main fixing post 3 on the nasal endoscope 1 and the suction tube 2 more stable and reliable.
[0041] The length of the bypass fixing hole can be set according to the actual situation, preferably not less than 1 cm; the diameter of the bypass fixing hole is preferably within 0.2-0.4 times the diameter of the nasal endoscope 1 or suction tube 2.
[0042] In a further preferred embodiment, to prevent the auxiliary fixation post from falling off during use and affecting the surgical outcome, one end of the nasal endoscope auxiliary fixation post is also connected to the main fixation post 3 via a connecting rope; to prevent the nasal endoscope auxiliary fixation post from falling off.
