Technical Field

[0001] The utility model relates to an auxiliary tool for ear surgery, in particular to an ear endoscope surgery supporting auxiliary device. Background Art

[0002] Due to its minimally invasive advantages, endoscopic ear surgery is particularly suitable for the treatment of external auditory canal cholesteatoma, chronic otitis media, tympanic membrane perforation and other diseases. It has become the mainstream of ear surgery, accounting for more than 85% of ear surgery. However, endoscopic ear surgery can only be performed with one hand, requiring the surgeon to hold the scope with one hand and operate the surgical instruments with the other hand, resulting in reduced surgical accuracy and increased difficulty of surgery.

[0003] Freeing the hand holding the scope has become an urgent issue. Secondly, long-term surgery makes it easy for heat to accumulate in the endoscope lens, which will cause certain thermal damage to the ear tissue. In addition, due to the narrow surgical cavity, the lens is easily contaminated by blood, and bone powder will also contaminate the lens if bone is ground during surgery. This will increase the movement of wiping the lens during surgery, resulting in a longer operation time. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments.

[0023] like Figure 1-Figure 4The otoscope surgery support auxiliary device shown includes a support frame 3, one end of the support frame 3 is connected to a multi-directionally adjustable connecting rod 1, the connecting rod 1 is installed on a fixed seat, the support frame sleeve clamps the otoscope, the support frame 3 forms a conduit at both edges, the outer end of the conduit is connected to a suction device or a flusher, and the inner end of the conduit forms a flushing port 6 or a suction port 7. The otoscope is connected to a computer and an otoscope display via a data cable. The otoscope image is transmitted to the computer, the computer recognizes the clarity of the image, and prompts the dangerous area of ​​the surgical area.

[0024] In one embodiment, the central body of the support frame 3 is a semi-hollow and semi-closed structure, and the central body is covered with an ear endoscope. This semi-closed structure can reduce the volume of the support frame and avoid occupying too much surgical space.

[0025] like Figure 1 As shown, the flushing pipe sleeve 4 on the left is connected to the flushing pipe, the upper end of the left conduit is the flushing device inlet 8, and the lower end is the flushing port 6, which opens inward. The design of the flushing port can not only reduce the temperature of the endoscope, but also maintain the clarity of the endoscope and prevent the mirror surface from being blocked by dirt.

[0026] The right side of the absorption tube sleeve 5 forms an aspirator connection port 9 at the top, which is connected to the aspirator, and the lower end forms a suction port. When the bone grinding power station is used in surgery, water can be discharged through the flushing port and suction can be used to suck the bone powder and blood in the surgical area in time, realizing the function of underwater operation.

[0027] In one embodiment, a temperature control probe is also provided at the inner end of the support frame 3. When the temperature control probe senses that the temperature of the inner lens end is greater than the first temperature threshold corresponding to the preset range (for example, 37 degrees), the controller sends an alarm signal after receiving the signal and displays it on the display screen with a yellow light. The operator can increase the amount of flushing liquid flow from the flushing port to take away more heat and control the head end temperature to be within the preset range.

[0028] When the temperature of the inner lens end is greater than the preset corresponding second temperature threshold (for example, 42 degrees), the second temperature threshold is higher than the first temperature threshold. After receiving the signal, the control component sends an alarm signal and displays it on the display screen, and the red light is displayed. Liquid flows out through the flushing port and the flushing port at the same time, thereby taking away more heat; the head end temperature is controlled to be within the preset range.

[0029] Specifically, the connecting rod 1 is a memory-type metal spring rod with arbitrary plasticity. The vertical angle of the connecting rod can be easily changed to facilitate the operation.

[0030] Specifically, the upper and lower ends of the connecting rod 1 are formed with thread heads 2, the fixed base is formed with thread openings 14 matching the thread heads, and the support frame is formed with internal threads 10 matching the thread heads 2. The threaded connection facilitates assembly and disassembly.

[0031] In one embodiment, the fixed base 11 includes a main body, one side of which is formed with a clamping portion consisting of an upper clamping plate 12 and a lower clamping plate 13, and an adjusting nut 15 is provided on the clamping portion for adjusting the size of the clamping opening of the clamping portion. The clamping portion is used to clamp the operating bed, and the adjusting nut can adjust the tightness of the clamping portion.

[0032] In one embodiment, the flusher includes a controller, a water pump and a display 17. The water outlet of the water pump is connected to the flusher inlet 8 on the support frame through a water pipe. The inlet of the water pump is connected to the water source and the foot switch 18 through a water pipe 16. The temperature control probe is connected to the controller and the display. The display displays the water flow rate and the temperature value detected by the temperature probe. The display contains red and yellow indicator lights and contains temperature display values.

[0033] The utility model has a simple structure, is easy to use, has multiple functions, and has a detection alarm function. It can not only free one hand of the surgeon, but also play the role of intraoperative flushing and suction. It can prevent blood and bone powder from contaminating the lens, and at the same time avoid damage to ear tissue due to high temperature, thus enhancing the safety of the operation.
