Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a minimally invasive tissue traction and positioning device that can reduce labor consumption and improve surgical efficiency. Background Art

[0002] During the operation, the skin needs to be incised first to expose the lesion under the skin. During the operation, in order not to affect the progress of the operation, the incised skin incision needs to be kept open all the time. This requires medical staff to keep the same action for a long time to pull the skin on both sides of the incision, which not only consumes labor and increases the surgical cost, but also affects the surgical efficiency due to uneven manual traction. Content of the Utility Model

[0003] The utility model mainly solves the above-mentioned existing technical problems; provides a minimally invasive tissue traction and positioning device that can reduce labor consumption and improve surgical efficiency.

[0004] In order to solve the above-mentioned existing technical problems, the utility model mainly adopts the following technical solutions:

[0005] A minimally invasive tissue traction and positioning device includes a flexible columnar body. A hook is provided at the front end of the body. A plurality of convex rings distributed along the axis of the body and integrally structured with the body are provided on the surface of the body. The planes of the convex rings are perpendicular to the axis of the body and parallel to each other;

[0006] The hook at the front end of the body is used to hook the skin at the incision. The convex rings can not only improve the structural strength of the body, facilitate pulling the body, but also expand the thickness of the connection area with the staple, and improve the connection strength of the staple.

[0007] Preferably, there are two hooks, and the planes of the two hooks are parallel to each other. The double hooks can improve the reliability of the body to hook the skin.

[0008] Preferably, the cross-section of the body is rectangular or circular, and the cross-section of the convex ring is rectangular or semi-circular or arc-shaped. The convex ring is convenient for the staple to be driven in.

[0009] Preferably, a pull ring integrally structured with the body is provided at the tail of the body, which is convenient for pulling the body.

[0010] Preferably, the material of the body is polytetrafluoroethylene or silica gel or polyurethane, and the hook is made of titanium alloy or stainless steel.

[0011] The beneficial effects of the present utility model are as follows: The traction positioning device adopts a flexible columnar body. The hooking hooks at the front section of the body are used to hook the incised skin and pull and open the skin incision. The convex rings on the body are stapled to the corresponding skin through a special skin stapler, achieving the purpose of positioning and fixing the skin incision. This not only eliminates the need for manual traction and reduces labor consumption, but also does not cause damage to the skin and improves the surgical efficiency.

[0014] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further specifically described.

[0015] Embodiment: A minimally invasive tissue traction positioning device of this embodiment, as Figure 1 shown, includes a flexible cylindrical body 1 with a body diameter of 3 mm and a length of 50 mm. Two hooking hooks 2 are designed at the front end of the body. The planes of the two hooking hooks are parallel to each other. A plurality of convex rings 3 distributed along the axis direction of the body and integrally structured with the body are designed on the surface of the body. The planes of the convex rings are perpendicular to the axis of the body and parallel to each other. The cross-section of the convex ring is semi-circular with a diameter of 5 mm, and the interval between the convex rings is 10 mm. A pulling ring 4 integrally structured with the body is designed at the tail of the body. The materials of the above-mentioned body, convex ring, and pulling ring are polytetrafluoroethylene, and the material of the above-mentioned hooking hook is stainless steel.

[0016] During use, after cutting the skin, the two hooking hooks at the front end of the body are used to hook one side of the skin at the incision. The body is pulled through the pulling ring at the tail of the body and the incision is opened to the required opening. The convex ring is stapled to the corresponding skin by using a special skin stapler to complete the positioning and fixing of one side of the incision skin. Similarly, the incision skin on the other side is positioned and fixed, and finally the opening positioning and fixing of the surgical skin incision are completed.

[0017] After completing the positioning and fixing of the incision skin, during the surgical process, the skin incision always remains in an open state without manual traction, greatly reducing labor consumption and also improving the surgical efficiency.

[0018] In the description of the present utility model, the technical terms "upper", "lower", "front", "rear", "left", "right", "longitudinal", "transverse", "inner", "outer", etc. indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, and are only for the convenience of describing and understanding the technical solution of the present utility model. The above description does not limit the present utility model, and the present utility model is not limited to the examples described above. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essence of the present utility model shall be regarded as the protection scope of the present utility model.
