Benefits of technology

This innovation allows surgeons to easily customizable create an effective way to work inside their own channels that are designed specifically for each patient's needs without causing harm or complications during procedures. It also helps reduce operating times while still providing stability when used over multiple types of bone fractures.

Problems solved by technology

This patented describes how surgeons use tools like drills to fix damaged bones together after they have been severely affected due to disease such as osteoarthritis (OA). Current methods involve making multiple cuts on each area where there're no significant damage caused by previous treatments. Additionally, existing solutions require long procedures involving cutting large areas before healing occurs, causing longer recovery times than needed.

Embodiment 1

[0036] see Figure 1 to Figure 7 As shown in the figure, a general-purpose adjustable fixed surgical channel for joint surgery includes a spreading plate 1, a movable bracket 2 and a tissue clip 3, and is characterized in that: Symmetrically placed, the front and rear sides of the two support plates are connected by a movable bracket 2, and the tissue clip 3 is disassembled and installed on the outer side wall of the opening plate 1; the center of the movable bracket 2 is a threaded rod 21, on which a number of threads are movably installed The ring 22, the left and right sides of the threaded rod 21 are hingedly connected to a support rod 23, and the other end of the support rod 23 is hinged to the opening plate 1; the tissue clip 3 is composed of two identical symmetrical installations.

[0037] A plurality of annular protrusions are arranged on the outer surface of the expansion plate 1 to increase the friction force; the diameter of the expansion plate 1 is 15.0-35.0mm, th...

Embodiment 2

[0045] Instructions:

[0046] First put the poke core 4 into the operation channel, close the movable bracket 2, and after making an incision on the patient, place a tissue clip 3 into the incision, and the splint 31 faces outside the incision, below the surface tissue;

[0047] Insert the retracted movable bracket 2 together with the spreading plate 1 from the incision, pass through the tissue clip 3, adjust the insertion depth of the spreading plate 1, and then adjust the position of the tissue clip 3 on the outside of the support plate;

[0048] Rotate the threaded rod 21 through the knob 24, so that the threaded ring 22 of the upper half of the threaded rod 21 moves downward, and the threaded ring 22 of the lower half of the threaded rod 21 moves upward, and the two supporting rods 23 are used. Push, then remove the poke core 4, and continue to adjust until the vision of the affected area is clear and the operation can be performed;

[0049] Take another tissue clip 3, th...

Embodiment 3

[0052] The present invention designs a universal adjustable fixed surgical channel for joint surgery. The device is provided with two semi-cylindrical spreading plates 1 and connected by a movable bracket 2, which can form a stable surgical channel, and the channel size is within a certain range. It can be adjusted freely and is suitable for surgery on different parts of the body of different patients. It has a wide range of use, saves operation time and reduces risks; the stretch plate 1 can protect important tissues such as blood vessels, nerves, ligaments, tendons, etc. Surgical risk; the tissue at the edge of the incision is clamped by two tissue clips 3, which reduces leakage of tissue fluid, prevents soft tissue from affecting the visual field, and improves surgical efficiency.

Abstract

The invention discloses a universal joint operation adjustable fixed operation channel, which comprises opening plates, movable supports and tissue clamps, the opening plates are semi-cylindrical, the two opening plates are symmetrically placed, the front sides and the rear sides of the two supporting plates are connected through the movable supports, and the tissue clamps are detachably mounted on the outer side walls of the opening plates; a threaded rod is arranged in the center of the movable support, a plurality of threaded rings are movably installed on the threaded rod, supporting rods are hinged to the left side and the right side of the threaded rod respectively, and the other ends of the supporting rods are hinged to the opening plate. The tissue clamp is formed by symmetrically installing two identical tissue clamps. A stable operation channel is arranged, the size of the channel can be adjusted, the application range is wide, operation time is saved, and risks are reduced; important tissues such as blood vessels, nerves, ligaments and tendons can be protected by the distraction plate, accidental injury in an operation is avoided, and the operation risk is reduced; the incision edge tissue is clamped through the two tissue clamps, tissue fluid leakage is reduced, the situation that the vision is affected by the soft tissue is avoided, and the operation efficiency is improved.
