[0048] Embodiment 1

[0049] like Figures 1 to 3 As shown, this embodiment provides a shoulder arthroscopy traction bracket, including a traction part 100 , a support part 200 and a fixing part 300 .

[0050] The support part 200 includes a vertical pole 210 and a pulley 220 located above the traction part 100. Specifically, the lower end of the vertical pole 210 is fixed to the fixed part 300, and the pulley 220 is indirectly connected to the vertical pole 210. The traction part 100 includes a restraining device 110, a traction body 120, and a traction rope 130 wound around the pulley 220. The restraining device 110 is located below the pulley 220, wherein the restraining device 110 is fixed to the arm of the human body when in use; the traction body 120 is located between the fixed part 300 and the pulley 220; the two ends of the traction body 120 are respectively a hinged end and a free end; the hinged end is hinged to the vertical pole 210, and the hinged end is connected to the vertical pole 210. 0 is the hinge point, and the traction body 120 can rotate around the hinge point in a vertical plane; the traction body 120 is movably connected with a counterweight 121 for applying traction during surgery, and the counterweight 121 is staggered from the hinge end; one end of the traction rope 130 is connected to the restraint device 110, and the other end is connected to the traction body 120 and is staggered from the hinge end. Specifically, the two ends of the traction rope 130 are the restraint end and the traction end, respectively. The restraint end is connected to the restraint device 110, and the traction end is movably connected to the traction body 120. The traction end and the hinge end are staggered to ensure that the traction force applied by the counterweight 121 can be effectively transmitted to the traction rope 130.

[0051] It should be noted that the traction body 120 may be a regular block shape, such as a cylinder, a cuboid or a triangular prism, etc., or may be an irregular polyhedron or a special-shaped body.

[0052] For the sake of convenience, this embodiment takes the traction body 120 as a rectangular parallelepiped as an example. The traction body 120 has six side surfaces: an upper side surface, a lower side surface, a left side surface, a right side surface, a front side surface and a rear side surface. The left side surface is located at the hinged end, and the right side surface is located at the free end.

[0053] As a preferred embodiment of the utility model, the vertical pole 210 is slidably connected with a connector 211, and the connector 211 is provided with a first locking device 211a for fixing the connector 211 on the vertical pole 210. The first locking device 211a is a conventional sliding locking structure. Specifically, the first locking device 211a adopts a component including a first locking pipe clamp, a first locking nut and a first locking bolt. The first locking bolt is sleeved on the first locking pipe clamp, and the first locking nut is spirally connected to the first locking bolt. The unlocking and locking are realized by the coordinated rotation of the first locking nut and the first locking bolt. In the unlocked state, the first locking pipe clamp can slide on the vertical pole 210, and the connector 211 can slide on the vertical pole 210 at this time; in the locked state, the connector 211 is fixed on the vertical pole 210 through the first locking pipe clamp. The hinged end of the traction body 120 is hinged to the connector 211 on the vertical pole 210. The height of the traction body 120 can be adjusted by adjusting the position of the connector 211 on the vertical pole 210 to adapt to the use of different surgical operators and avoid the traction body 120 being too high or too low.

[0054] It should be noted that the first locking device 211a can also adopt other existing conventional structures, for example: an assembly including a quick-release bolt rod and a connecting pipe clamp, the connecting pipe clamp is provided with a locking hole matching the quick-release bolt rod, and the quick-release bolt rod is installed on the locking hole; for example, an assembly including a chuck clamp and a bolt; for example, an assembly including a buckle and a connecting pipe clamp.

[0055] As a preferred embodiment of the present invention, a blind hole 122 arranged along the length direction of the traction body 120 is provided at the end of the free end of the traction body 120, and a counterweight 121 is slidably arranged in the blind hole 122, and a spring 123 is also arranged in the blind hole 122. More specifically, the counterweight 121 is spherical, the blind hole 122 is cylindrical, one end of the spring 123 abuts or is connected to the bottom of the blind hole 122, and the other end of the spring 123 abuts or is connected to the counterweight 121. An inner convex ring is provided at the mouth of the blind hole 122, and an adjusting bolt 124 is spirally connected to the inner convex ring, and the adjusting bolt 124 abuts on the counterweight 121. The adjusting bolt 124 and the spring 123 are used to adjust the position of the counterweight 121 in the blind hole 122. The adjusting bolt 124 and the spring 123 cooperate with each other, so that the position of the counterweight 121 can be conveniently adjusted and the counterweight 121 can be effectively fixed. By rotating the adjusting bolt 124, the distance between the adjusting bolt 124 and the bottom of the blind hole 122 can be increased or decreased, thereby increasing or decreasing the distance between the counterweight 121 and the bottom of the blind hole 122, and also increasing or decreasing the distance between the counterweight 121 and the hinge point, so that the tension on the traction rope 130 can be increased or decreased while the connection position between the traction rope 130 and the traction body 120 remains unchanged.

[0056] As a preferred embodiment of the utility model, a viewing groove 128 is provided on the side wall of the blind hole 122 to penetrate the outer wall of the traction body 120. Specifically, the viewing groove 128 penetrates the front side of the traction body 120. The maximum width of the viewing groove 128 is smaller than the maximum thickness of the counterweight 121, ensuring that the counterweight 121 can only slide in the blind hole 122. The viewing groove 128 is used to observe the position of the counterweight 121 in the blind hole 122.

[0057] As a preferred embodiment of the present invention, the traction body 120 is further provided with a slide rail 125, which is located between the hinged end and the free end, and is arranged along the length direction of the traction body 120. Specifically, the slide rail 125 is fixed on the rear side of the traction body 120 and is parallel to the upper side of the traction body 120. A sliding member 126 is slidably arranged on the slide rail 125, and a second locking device 127 for fixing the sliding member 126 on the slide rail 125 is provided on the sliding member 126; the traction rope 130 is connected to the traction body 120 through the sliding member 126. Through the cooperation of the slide rail 125 and the sliding member 126, the position of the traction end on the traction body 120 can be efficiently adjusted. The second locking device 127 is a conventional sliding locking structure. Specifically, the second locking device 127 adopts a component including a second locking nut and a second gasket. The surface where the sliding member 126 and the slide rail 125 contact and slide with each other is the sliding surface. The second gasket is arranged on the sliding surface of the sliding member 126, specifically located between the sliding member 126 and the slide rail 125. The second locking nut is spirally connected to the sliding member 126 and abuts against the second gasket. The unlocking and locking are achieved by adjusting the second locking nut. In the unlocking state, the sliding member 126 can slide on the slide rail 125; in the locking state, the sliding member 126 cannot slide on the slide rail 125. The traction end of the traction rope 130 is fixed on the sliding member 126 and is indirectly connected to the traction body 120 through the sliding member 126. The distance between the traction end of the traction rope 130 and the hinge point is increased or decreased by sliding the position of the sliding member 126, so that the tension on the traction rope 130 can be reduced or increased when the position of the counterweight 121 remains unchanged.

[0058] It should be noted that the second locking device 127 can also adopt other existing conventional structures, for example: an assembly including a quick-release bolt rod and a connecting pipe clamp, the connecting pipe clamp is provided with a locking hole matching the quick-release bolt rod, and the quick-release bolt rod is installed on the locking hole; for example, an assembly including a chuck clamp and a bolt; for example, an assembly including a buckle and a connecting pipe clamp.

[0059] By rotating the adjusting bolt 124 to adjust the position of the counterweight 121 and / or sliding the slider 126 to adjust the position of the traction end of the traction rope 130, the tension on the traction rope 130 can be increased or decreased when the weight of the counterweight 121 is inconvenient to maintain, and the operation is simple and convenient. For example, when the position of the counterweight 121 remains unchanged, sliding the slider 126 toward the free end of the traction body 120 can reduce the tension on the traction rope. Similarly, sliding the slider 126 toward the hinged end of the traction body 120 can increase the tension on the traction rope; when the position of the slider 126 remains unchanged, rotating the adjusting bolt 124 to push the counterweight 121 against the free end of the traction body 120 can increase the tension on the traction rope. Similarly, rotating the adjusting bolt 124 to push the counterweight 121 against the hinged end of the traction body 120 can reduce the tension on the traction rope.

[0060] As a preferred embodiment of the present invention, two tension measuring devices 131 are provided on the traction rope 130. Specifically, one of the two tension measuring devices 131 is located between the traction body 120 and the pulley 220, and the other is located between the restraining device 110 and the pulley 220, for monitoring the magnitude of the traction force during the operation.

It should be noted that when only one limiting ring 213 is provided on the vertical pole 210, it is preferred that the limiting ring 213 is provided on the lower side of the traction body 120, so as to prevent the traction force from being too large and causing the traction body 120 to rotate downward at an excessively large angle.

[0062] It should be noted that the fourth locking device 214 has the same structure as the first locking device 211 a , which will not be described in detail herein.
