Description

Technical Field

[0001] The utility model relates to a vertebral plate retractor foot-operated tension belt. Background Art

[0002] The lamina retractor is an important surgical instrument used in lumbar spine surgery. In the prior art, the surgical retractor needs to be manually operated and pulled, which causes congestion at the surgical site and is not conducive to the orderly progress of the surgery. Secondly, the hand pulling action is maintained for a long time. When the pulling is not in place, it will affect the surgeon's surgical field of view.

[0003] Based on the above problems, we designed a lamina retractor foot-operated tension belt that can be used to pull the lamina retractor by stepping on it. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a lamina retractor foot-operated tension belt which can be used to pull the lamina retractor in a foot-operated manner.

[0005] The utility model is realized by the following technical solutions:

[0006] A vertebral plate retractor foot-operated tension belt comprises a tension belt and a foot-operated device cooperating with the tension belt, wherein the tension belt passes through the foot-operated device, a plurality of limit blocks are arranged at one end of the tension belt, a ring body is arranged at the other end of the tension belt, the limit blocks pass through the ring body, and when the tension belt is tightened, the limit blocks limit the displacement of the ring body.

[0007] Preferably, the pedal device comprises a foot pedal and a belt-threading tube, the belt-threading tube passes through the foot pedal, and the tension belt passes through the belt-threading tube and can be displaced along the belt-threading tube.

[0008] Preferably, the belt threading tube has two pipe openings, and the distance between the two pipe openings gradually shortens upwards.

[0009] Preferably, the belt tube and the foot pedal are an integrated structure.

[0010] Preferably, the belt tube and the foot pedal are split structures, and the belt tube is fixed after passing through the foot pedal.

[0011] Preferably, anti-slip grooves are provided on the upper and lower end surfaces of the foot pedal.

[0012] The beneficial effects of the utility model are:

[0013] This device uses a tension belt for traction. The surgeon uses the soles of the feet to step on it to generate tension, which drives the vertebral plate retractor to pull outward to complete the traction at the vertebral plate position. No assistant is required for auxiliary operation, which makes the standing position of the surgeon more relaxed and maintains stable traction to ensure the effective implementation of the operation.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, in the description of the present invention, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "set", "socket", "connect", "penetrate", "plug in" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1 and Figure 2 The vertebral plate retractor foot-operated tension belt shown in the figure comprises a tension belt 1 and a foot-operated device 2 cooperating with the tension belt 1, wherein the tension belt 1 passes through the foot-operated device 2, a plurality of limit blocks 11 are arranged at one end of the tension belt 1, a ring body 12 is arranged at the other end of the tension belt 1, the limit blocks 11 pass through the ring body 12, and when the tension belt 1 is tightened, the limit blocks 11 limit the displacement of the ring body 12.

[0026] See also Figure 5 As shown, the matching position of the ring body 12 and the limit block 11 is adjusted according to the height of the end of the lamina hook from the ground, so that when the pedal device 2 is stepped on, the lamina hook can generate sufficient outward pulling force.

[0027] See also Figure 3 and Figure 4 As shown, the pedal device 2 includes a foot pedal 21 and a belt-threading tube 22 . The belt-threading tube 22 passes through the foot pedal 21 . The tension belt 1 passes through the belt-threading tube 22 and can be displaced along the belt-threading tube 22 .

[0028] In the above technical solution, the arrangement of the strap tube 22 can limit the left-right displacement of the sole of the foot when the sole of the foot steps on the foot pedal 21 .

[0029] The function of the pedal 21 is to increase the contact area with the ground and the contact area with the sole of the foot, so that the pedaling is more stable.

[0030] See also Figure 3 As shown, the belt threading tube 22 has two pipe openings 221, and the distance between the two pipe openings 221 gradually shortens upward.

[0031] In the above technical solution, two pipe openings 221 close to each other are used, so that the spacing between the tension belts 1 passing through the belt threading tube 22 can be reduced, thereby playing a gathering effect.

[0032] In this embodiment, the belt tube 22 and the foot pedal 21 are an integrated structure, and are integrally formed by injection molding.

[0033] See also Figure 4 As shown, anti-slip grooves 232 are provided on the upper and lower end surfaces of the foot pedal 21 .

[0034] The anti-skid groove 232 can increase the friction between the foot pedal 21 and the ground, as well as the friction between the foot pedal 21 and the sole of the foot, making the pedaling more stable.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
