Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an endoscope fixation device. Background Technology
[0002] In minimally invasive spinal surgery, endoscopes are commonly used to assist medical staff in observing the lesion site. Once the endoscope's observation position is determined during surgery, it needs to be stabilized in that position. Traditional methods of stabilizing endoscopes require medical staff to maintain the same posture for extended periods while holding the endoscope, requiring a high degree of concentration. This can easily lead to muscle strain and fatigue, affecting surgical safety and hindering the stable use of the endoscope during surgery.
[0003] To free up manpower and ensure the stable use of endoscopes during surgery, endoscope supports are currently widely used for endoscope stability and to allow for adjustments to the endoscope's position and angle. However, existing supports require a fixing structure to connect to the endoscope, and some existing fixing structures suffer from instability and cumbersome operation. For example, with set-screw and magnetic fixation devices, the set-screw device requires sliding the endoscope from the lens end onto the tube and then securing it with a set screw. Separating the endoscope from the support requires removing it from the patient, increasing the complexity of the procedure. Furthermore, set-screw fixation is prone to damaging the endoscope, has a small fixing area, and poor stability. Magnetic fixation devices rely on magnetic attraction to hold the endoscope, but the magnetic components can lose magnetism due to external factors such as high temperatures and strong magnetic fields, resulting in low clamping stability. Therefore, there is an urgent need for a quick-disassembly auxiliary device for hospital endoscopic surgery to solve these problems. Utility Model Content

It should be understood that the given embodiments are only one of the implementation methods and do not represent all embodiments.
[0022] In this article, terms such as "inner" and "outer" are established based on the positional relationships shown in the attached drawings.

[0023] Combined with appendix Figure 1 -Appendix Figure 3 An endoscope fixing device includes a base 1, a clamping arm, and a locking nut 5. The clamping arm includes a first half-clamp 2 and a second half-clamp 3, with one end of the first half-clamp 2 and the second half-clamp 3 hinged together. The other ends of the first half-clamp 2 and the second half-clamp 3 are detachably connected by the locking nut 5. When the first half-clamp 2 and the second half-clamp 3 are connected, a clamping groove 11 for clamping the endoscope 12 is formed between them. Specifically, the first half-clamp 2 and the second half-clamp 3 each have an arc-shaped groove on opposite sides. When the first half-clamp 2 and the second half-clamp 3 are connected, the two arc-shaped grooves form a circular groove. The arc surface of the circular groove fits the shape of the endoscope 12 tube better, so that the first half-clamp 2 and the second half-clamp 3 have a larger and closer contact surface with the endoscope 12, thereby improving the clamping effect of the first half-clamp 2 and the second half-clamp 3 on the endoscope 12.
[0024] One end of the base 1 is connected to the endoscope 12 support frame, and the other end of the base 1 is fixedly connected to the first half buckle 2.
[0025] Specifically, the first half-clamp 2 has a first pin hole at its end away from the locking nut 5, and the second half-clamp 3 has a second pin hole at its end away from the locking nut 5. The first pin hole and the second pin hole are coaxially arranged, and a first pin 8 is connected to the first pin hole and the second pin hole. The first half-clamp 2 and the second half-clamp 3 are rotatably connected to the first pin 8 through the first pin hole and the second pin hole, respectively. The axial direction of the first pin, the first pin hole, and the second pin hole is the same as the axial direction of the clamping groove 11. When the first half-clamp 2 and the second half-clamp 3 are not connected by the locking nut 5, the two half-clamps can rotate relative to each other around the first pin 8, and the two half-clamps can move closer or further apart when rotating. When it is necessary to place the endoscope 12 between the two half-clamps or to detach it from the two half-clamps, the first half-clamp 2 and the second half-clamp 3 are moved away from each other; when it is necessary to fix the endoscope 12, the two half-clamps are moved closer together to clamp the endoscope 12.
[0026] Specifically, the locking nut 5 includes a threaded rod 4 and a nut 5. One end of the threaded rod 4 is hinged to the first half-clamp 2, and the other end of the threaded rod 4 is threaded to the nut 5. The second half-clamp 3 has a groove for accommodating the threaded rod 4 at one end near the locking nut 5. The outer diameter of the nut 5 is larger than the radial dimension of the groove.
[0027] When the first half-clamp 2 and the second half-clamp 3 are connected, the threaded rod 4 is located in the groove, and the nut 5 is located on the side of the second half-clamp 3 away from the first half-clamp 2.
[0028] When connecting the first half-clamp 2 and the second half-clamp 3, first position the endoscope 12 tube body between the two half-clamps and bring the two half-clamps close together to form a clamping groove 11, so that the endoscope 12 is in the clamping groove 11; then rotate the threaded rod 4 so that the threaded rod 4 is in the groove of the second half-clamp 3, at which point the end of the second half-clamp 3 is located between the nut 5 and the first half-clamp 2; tighten the nut 5 so that the nut 5 is close to the second half-clamp 3 until the nut 5 is tightened, and the connection of the first half-clamp 2 and the second half-clamp 3 is completed.
[0029] Specifically, the first half-buckle 2 is fixed with a second pin 9 at one end near the locking nut 5, and the threaded rod 4 is provided with a third pin hole 10 at one end away from the nut 5. The second pin 9 passes through the third pin hole 10, and the threaded rod 4 is rotatably connected to the second pin 9 through the third pin hole 10.
[0030] The axis of the second pin 9 is the same as the axis of the clamping groove 11. The end face of the second half-clamp 3 near the locking nut 5 is a groove opening. The axis of the third pin hole 10 is consistent with the diameter direction of the threaded rod 4. This allows the threaded rod 4 to rotate in a direction perpendicular to the axis of the endoscope 12.
[0031] Specifically, a rotating plate 6 is fixed to the outside of the nut 5. There are two rotating plates 6, which are symmetrically arranged. The two rotating plates 6 provide the user with an operating part to turn the nut 5, making it convenient for the user to rotate the nut 5.
[0032] Specifically, a limiting plate 7 is provided at the end of the threaded rod 4 near the nut 5, and the radial dimension of the limiting plate 7 is larger than the inner diameter of the nut 5. The limiting plate 7 prevents the nut 5 from detaching from the threaded rod 4.
[0033] Specifically, the base 1 has a U-shaped groove at the end away from the clamping arm, and the rod of the endoscope support frame connecting and fixing device is embedded in the U-shaped groove. More specifically, the diameter of the rod of the endoscope support frame connecting and fixing device is not less than the radial dimension of the U-shaped groove.
[0034] Instructions for use: When fixing the endoscope 12, first position the threaded rod 4 outside the groove, then move the first half-clamp 2 and the second half-clamp 3 away from each other; place the tube part of the endoscope 12 to be fixed between the two half-clamps, then move the two half-clamps closer to each other until the opposite sides of the two half-clamps are in contact with the outer wall of the endoscope 12; rotate the threaded rod 4 so that the threaded rod 4 is in the groove, then tighten the nut 5 to complete the fixing of the endoscope 12.
[0035] When it is necessary to disassemble the endoscope 12, loosen the nut 5, rotate the threaded rod 4 to disengage the threaded rod 4 from the groove, and then rotate the first half buckle 2 or the second half buckle 3 to move the two half buckles away from each other, so that the endoscope 12 can be removed.
