Description

Technical Field

[0001] The present invention relates to the technology of medical instruments, and particularly to a technology of a shoulder arthroscopic balloon dilator. Background Art

[0002] Most diseases such as injuries, fractures, dislocations, etc. around the shoulder joint are treated by shoulder arthroscopic surgery. When performing shoulder arthroscopic surgery, medical staff usually use the method of continuously perfusing liquid into the shoulder joint cavity to dilate the shoulder joint cavity, so as to provide an operation space and vision for minimally invasive arthroscope. However, if the operation time is long, continuously perfusing liquid into the shoulder joint cavity for a long time will cause swelling of the shoulder joint and surrounding tissues, thus affecting the operation. Moreover, sometimes a small amount of blood will be mixed into the perfusate, resulting in a more blurred operation field of vision. Summary of the Invention

[0003] Aiming at the defects existing in the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a shoulder arthroscopic balloon dilator that can dilate the shoulder joint cavity during the operation, provide a clear operation field of vision for shoulder arthroscopic surgery, and can effectively avoid swelling of the shoulder joint and surrounding tissues.

[0004] In order to solve the above technical problem, a shoulder arthroscopic balloon dilator provided by the present invention is characterized in that: it includes a main air guide tube and a pressure gauge; The main air guide tube is a flexible tube with an open left end and a closed right end. The left end pipe orifice of the main air guide tube is butted against the pressure measuring port of the pressure gauge. A bypass tube communicating with the lumen of the main air guide tube is fixed on the left wall of the main air guide tube. An air guide valve for controlling the on-off of the bypass tube is provided on the bypass tube. A traction wire is fixed at the right end of the main air guide tube. Two air guide branches are fixed in the middle of the main air guide tube. The air guide branches are flexible tubes; Two sliding sleeves capable of sliding left and right are sleeved on the middle part of the outer wall of the main air guide tube. An airbag is fixed at the upper end of each of the two sliding sleeves. The cavities of the two airbags are respectively communicated with the lumen of the main air guide tube through the two air guide branches.

[0005] The shoulder arthroscopic balloon dilator provided by the present invention can use the airbags on the main air guide tube to dilate the shoulder joint cavity during the operation, provide a clear operation field of vision for shoulder arthroscopic surgery, can effectively avoid swelling of the shoulder joint and surrounding tissues compared with the existing method of continuously perfusing liquid, and the distance between the two airbags can be adjusted, and it can be used for shoulder joint cavities of different sizes. Brief Description of the Drawings

[0006] Figure 1 is the front view of the shoulder arthroscopic balloon dilator according to the embodiment of the present invention when the two airbags are in a deflated state; Figure 2 is the front view of the shoulder arthroscopic balloon dilator according to the embodiment of the present invention when the two airbags are in an inflated state. Detailed implementation mode

[0007] The following further describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, these embodiments do not limit the present invention. Any similar structures and their similar changes of the present invention should be included in the protection scope of the present invention. The commas in the present invention all represent the relationship of "and".

[0008] As Figure 1 - Figure 2 shown, a shoulder arthroscopic balloon dilator provided by an embodiment of the present invention includes a main air guide pipe 1 and a pressure gauge 3; The main air guide pipe 1 is a flexible pipe with an open left end and a closed right end. The left end pipe orifice of the main air guide pipe 1 is butted against the pressure measuring port of the pressure gauge 3. A bypass pipe 2 communicating with the lumen of the main air guide pipe is fixed on the left part of the outer wall of the main air guide pipe 1. An air guide valve 4 for controlling the on-off of the bypass pipe is provided on the bypass pipe 2. A traction wire 5 is fixed at the right end of the main air guide pipe 1. Two air guide branch pipes 8 are fixed in the middle of the main air guide pipe 1. The air guide branch pipes 8 are flexible pipes; Two sliding sleeves 6 capable of sliding left and right are sleeved on the middle of the outer wall of the main air guide pipe 1. An airbag 7 is fixed at the upper end of each of the two sliding sleeves 6. The cavities of the two airbags 7 are respectively communicated with the lumen of the main air guide pipe 1 through the two air guide branch pipes 8.

[0009] The embodiment of the present invention is used to dilate the shoulder joint cavity during shoulder arthroscopic surgery. Its usage method is as follows: In the initial state, the two airbags 7 are in a deflated state ( Figure 1 the state shown), and at this time, according to the size of the patient's shoulder joint cavity, the distance between the two airbags 7 is adjusted by sliding the two sliding sleeves 6; During shoulder arthroscopic surgery, first use a clamp to send the right part of the main air guide pipe 1 into the shoulder joint cavity through an incision on the patient's shoulder, then use a wire gripper to grab the traction wire 5 from another incision on the patient's shoulder and pull it out of the patient's body, and then use the traction wire 5 to pull the main air guide pipe 1 to make the two airbags 7 reach the position to be dilated. At this time, the main air guide pipe 1 is bent into an arc. At this time, connect the bypass pipe 2 to a carbon dioxide high-pressure gas source and open the air guide valve 4. Carbon dioxide gas then enters the two airbags 7 through the bypass pipe 2, the main air guide pipe 1, and the air guide branch pipes 8, driving the two airbags 7 to expand ( Figure 2 the state shown), dilating the shoulder joint cavity, so that the surgical site between the two airbags 7 has a clear view, facilitating surgical operation; the air pressure of the airbag can be monitored through the pressure gauge 3. After the air pressure of the airbag reaches the predetermined value, close the air guide valve 4 to keep the dilating force of the two airbags 7 within a suitable range; After the surgical operation is completed, disconnect the bypass pipe 2 from the carbon dioxide high-pressure gas source, then open the air guide valve 4, release the air in the two airbags 7 to make the two airbags 7 return to the deflated state, and then pull out the main air guide pipe 1 from the shoulder joint cavity.
