Description

Technical Field

[0001] The invention belongs to the technical field of surgical positioning and navigation, and in particular relates to a magnetic cotton sheet used for intraoperative positioning and tracking. Background Art

[0002] Current surgical positioning and navigation technology can achieve very accurate real-time tracking of surgical instruments and lesions, but there are still technical bottlenecks for accurate navigation of the anatomical levels around the lesions: first, the deformation of the soft tissue causes the surrounding anatomical levels to deform, which can easily lead to the loss of the correct anatomical level during the operation. The wrong anatomical level not only causes incomplete lesion clearance, but also easily causes accidental damage to surrounding organs. In addition, due to the lack of an overall view of the local anatomical tissue level in the limited space of a single channel, it is very easy to cause misinterpretation of the anatomical level and loss of operation direction.

[0003] Therefore, real-time positioning at the anatomical level combined with preoperative imaging results is crucial for accurate surgical operations. However, there are currently no materials or related products for intraoperative dynamic positioning marking. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a magnetic cotton sheet for intraoperative positioning and tracking, aiming to solve the technical problem that existing surgical instruments cannot achieve precise positioning.

[0005] The present invention adopts the following technical solution:

[0006] A magnetic cotton sheet for intraoperative positioning and tracking, the magnetic cotton sheet comprising a traction rope and a hygroscopic cotton sheet folded in half to form a double-layer structure, a thin adhesive layer of magnetic material filled between the double-layer structure, the hygroscopic cotton sheet with the double-layer structure and the thin adhesive layer of magnetic material compacted, a wire hole opened at the folded position of the hygroscopic cotton sheet, the traction rope passes through the wire hole and is then fastened with a transversely arranged magnetic rod, the length of the magnetic rod being greater than the diameter of the wire hole.

[0007] Furthermore, the traction rope is a thin and long cotton thread, and the length of the cotton thread is longer than the folded length of the moisture-absorbing cotton sheet.

[0008] Furthermore, the thin adhesive layer of magnetic material is iron powder or Fe3O4 particles.

[0009] Furthermore, the edge of the moisture-absorbing cotton sheet is sealed with stitches.

[0010] The beneficial effects of the present invention are as follows: the present invention provides a magnetic cotton sheet for intraoperative positioning and tracking, which can not only absorb the surrounding blood exudate, but also display the position in real time under a magnetic environment, and then play a very important role in guiding the identification of surgical anatomical levels by combining preoperative imaging features, which can help surgeons significantly reduce surgical complications and greatly shorten the operation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural diagram of a magnetic cotton sheet for intraoperative positioning and tracking provided by an embodiment of the present invention;

[0012] Figure 2 It is a structural diagram of a traction rope provided by an embodiment of the present invention with a magnetic rod. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0015] like Figure 1 , 2 As shown, the magnetic cotton sheet for intraoperative positioning and tracking provided in this embodiment includes a traction rope 1 and a hygroscopic cotton sheet 2 folded in half to form a double-layer structure, a thin adhesive layer 3 of magnetic material is filled between the double-layer structure, the hygroscopic cotton sheet 2 of the double-layer structure is compacted with the thin adhesive layer 3 of magnetic material, a wire hole is opened at the folded position of the hygroscopic cotton sheet 2, and the traction rope 1 is passed through the wire hole and then fastened with a transversely arranged magnetic rod 4, and the length of the magnetic rod is greater than the aperture of the wire hole.

[0016] During surgery, the magnetic cotton pad is introduced into the surgical anatomical layer, which can absorb the surrounding blood exudate and, based on the guidance of preoperative imaging, can also achieve precise navigation of the anatomical layer, and the magnetic cotton pad can be conveniently removed at any time through the traction rope. The magnetic rod provided in this embodiment can play a limiting role, and the magnetic rod has magnetism and can also play a positioning role.

[0017] As a specific structure, the traction rope is a thin and long cotton thread, and the length of the cotton thread is longer than the folded length of the moisture-absorbing cotton sheet, ensuring that a section of the cotton thread remains outside the body, making it easy to take out the magnetic cotton sheet.

[0018] In addition, the thin adhesive layer of magnetic material is iron powder or Fe3O4 particles, and the thin adhesive layer of magnetic material can display the position in real time under a magnetic environment.

[0019] At the same time, the edge of the moisture-absorbing cotton sheet is sealed with stitches to prevent the thin adhesive layer of the magnetic material from falling off.

[0020] The magnetic cotton sheet provided by the present invention can not only absorb surrounding blood exudate, but also display the position in real time under a magnetic environment, which can help surgeons significantly reduce surgical complications and greatly shorten the operation time.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
