Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an MR interventional surgery positioner. Background Art

[0002] Interventional MRI is the use of MRI-guided instruments to diagnose or treat diseases. As an interventional guidance tool, MRI has advantages that other imaging methods cannot match. It has excellent tissue contrast and sub-millimeter spatial resolution, which is beneficial for lesion location and interventional guidance. More importantly, MRI has the ability to reconstruct multiple planes and three-dimensional volumes, which can comprehensively evaluate the important anatomical relationship between the interventional target and adjacent tissues.

[0003] At present, there is no unique locator for MR surgery. Doctors only use thick needle tubes to fill water, seal them with tape, and stick them to the skin surface with tape when positioning. Since the thick tube has no stickiness, it must be taped every time it is positioned. If the thick tube is not sealed after water is filled, it will leak. The thick tube is simple to make and easy to break. Therefore, designing a locator for MR interventional surgery is an urgent problem to be solved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an MR interventional surgery locator, which can provide a high-signal image for a doctor during an MR interventional surgery scan, so that the doctor can measure the location of the lesion based on the high-signal image and the entire tomographic scan image.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A MR interventional surgery positioner comprises a packaging layer, a bonding layer and at least one indication layer.

[0007] The adhesion layer is used for adhering to the patient's skin.

[0008] The at least one indicating layer is configured to be encapsulated between the conforming layer and the encapsulation layer.

[0009] The at least one indicator layer is used to form at least one high signal image during MR scanning of the lower epidermis, so that the doctor can measure the location of the lesion based on the at least one high signal image and the entire tomographic image.

[0010] In the MR interventional surgery positioner provided in at least one embodiment of the present disclosure, the packaging layer and the front side of the bonding layer are fixedly connected.

[0011] In the MR interventional surgery locator provided in at least one embodiment of the present disclosure, the front sides of the packaging layer and the bonding layer are connected by bonding, which has good sealing performance, has a good positioning effect on the indicator layer, and can prevent the indicator layer from being displaced.

[0012] An adhesive layer and a release paper layer are sequentially arranged on the back of the laminating layer, and the release paper layer is used to protect the adhesive layer to prevent the adhesive layer from being contaminated before use.

[0013] In the MR interventional surgery locator provided in at least one embodiment of the present disclosure, the indicator layer is a capsule.

[0014] The capsule is filled with a medium.

[0015] In the MR interventional surgery positioner provided in at least one embodiment of the present disclosure, the packaging layer is transparent. The packaging layer adopts a transparent design, which can facilitate medical staff to observe the condition of the capsule and check the condition of the capsule before surgery, thereby avoiding leakage of the capsule and affecting surgery and positioning.

[0016] In the MR interventional surgery positioner provided in at least one embodiment of the present disclosure, the packaging layer, the bonding layer and the capsule are all arranged in a long strip shape.

[0017] The lengths of the packaging layer and the bonding layer are both greater than the length of the capsule.

[0018] The widths of the packaging layer and the bonding layer are both greater than the width of the capsule.

[0019] In the MR interventional surgery positioner provided in at least one embodiment of the present disclosure, at least one end of the bonding layer is configured to be not covered by the adhesive layer. When in use, since one end of the bonding layer is not covered by the adhesive layer, it is convenient for medical staff to peel off the release paper layer, and it is also convenient for the user to tear off the MR interventional surgery positioner after surgery.

[0020] In the MR interventional surgery positioner provided in at least one embodiment of the present disclosure, the medium is pure water or physiological saline.

[0021] The beneficial effects of the utility model are as follows: before the operation begins, the patient can lie supine or prone according to the location of the lesion, and stick the MR interventional surgery locator on the skin at the approximate location of the lesion. Then, during the intraoperative scan, it can be seen that the MR interventional surgery locator forms a high-signal image on the skin surface. The doctor can measure the specific location of the lesion based on this image combined with the entire tomography image. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0033] In the embodiments, it should be understood that the orientation or position relationship indicated by the terms "between", "on", "end", "back", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms such as installation, connection and connection should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Currently, there is no unique locator for MR surgery. Doctors simply use a thick syringe to inject water, seal it with tape, and then stick it to the skin surface with tape when positioning.

[0036] ①The thick tube has no stickiness, so it needs to be taped each time for positioning.

[0037] ②After the thick pipe is filled with water, it is not sealed and often leaks.

[0038] ③Thick tubes are easy to make and break easily.

[0039] Therefore, in order to solve the above problems, the embodiment provides an MR interventional surgery locator to solve the problem that the current homemade instruments need to be filled with water and leak; there is no need to use adhesive tape every time during use, which improves the efficiency of the operation; and the MR interventional surgery locator provided by the embodiment is safe and environmentally friendly, and each patient can use the locator individually, which is hygienic and safe.

[0040] At the same time, this MR interventional surgery locator also has an intraoperative positioning guidance function. During the real-time scanning and needle insertion process during the operation, the doctor can use this MR interventional surgery locator to guide the needle insertion. The MR machine scans without radiation and can scan in real time during the operation. The doctor operates in the operating room during the scanning, and collaborates with the technicians in the operating room through the player. When the locator is used during real-time dynamic scanning, the high-signal image can accurately guide the surgical needle insertion.

[0041] Example 1

[0042] like Figure 1 and 2 As shown, this embodiment provides an MR interventional surgery positioner, including a packaging layer 10 , a bonding layer 20 and an indication layer 30 .

[0043] Furthermore, the adhesion layer 20 is used to be adhered to the patient's skin. The indication layer 30 is configured to be encapsulated between the adhesion layer 20 and the encapsulation layer 10 .

[0044] Furthermore, the indicator layer 30 is used to form a high signal image during MR scanning of the lower epidermis, so that the doctor can measure the location of the lesion based on the high signal image and the entire tomographic image.

[0045] Before the operation begins, the patient can lie supine or prone according to the location of the lesion and stick the MR interventional surgery locator on the skin at the approximate location of the lesion. During the intraoperative scan, the MR interventional surgery locator can be seen to form a high-signal image on the skin surface.

[0046] In this embodiment, the back surface of the encapsulation layer 10 and the front surface of the bonding layer 20 are fixedly connected.

[0047] Specifically, the back surface of the encapsulation layer 10 and the front surface of the bonding layer 20 are connected by bonding, which has good sealing performance and has a good positioning effect on the indication layer 30, thereby preventing the indication layer 30 from being displaced.

[0048] In this embodiment, an adhesive layer 50 and a release paper layer 40 are sequentially disposed on the back of the laminating layer 20 . The release paper layer 40 is used to protect the adhesive layer 50 to prevent the adhesive layer 50 from being contaminated before use.

[0049] In this embodiment, the indicator layer 30 is a capsule filled with a medium (not shown).

[0050] Exemplarily, the capsule is made of medical PVC material, and the medium can be, but is not limited to, one of pure water and physiological saline.

[0051] In this embodiment, the encapsulation layer 10 is transparent, which can facilitate medical staff to observe the condition of the capsule and check the condition of the capsule before surgery, thereby preventing the capsule from leaking and affecting surgery and positioning.

[0052] In this embodiment, the packaging layer 10, the bonding layer 20 and the capsule body are all arranged in a long strip shape.

[0053] Furthermore, the lengths of the encapsulation layer 10 and the bonding layer 20 are both greater than the length of the capsule, and the widths of the encapsulation layer 10 and the bonding layer 20 are both greater than the width of the capsule.

[0054] In this embodiment, one end of the bonding layer 20 is configured to be uncovered by the adhesive layer 50. When in use, since one end of the bonding layer 20 is uncovered by the adhesive layer, it is convenient for medical staff to peel off the release paper layer 40, and it is also convenient for users to tear off the MR interventional surgery positioner after surgery.

[0055] Example 2

[0056] like Figure 2 and 3 As shown, this embodiment provides an MR interventional surgery positioner, including a packaging layer 10 , a bonding layer 20 and an indication layer 30 .

[0057] Furthermore, the adhesion layer 20 is used to be adhered to the patient's skin. The indication layer 30 is configured to be encapsulated between the adhesion layer 20 and the encapsulation layer 10 .

[0058] Furthermore, the indicator layer is used to form a high signal image during MR scanning of the lower epidermis, thereby enabling the doctor to measure the location of the lesion based on the high signal image and the entire tomographic image.

[0059] Before the operation begins, the patient can lie supine or prone according to the location of the lesion and stick the MR interventional surgery locator on the skin at the approximate location of the lesion. During the intraoperative scan, the MR interventional surgery locator can be seen to form a high-signal image on the skin surface.

[0060] In this embodiment, an adhesive layer 50 and a release paper layer 40 are sequentially disposed on the back of the laminating layer 20 . The release paper layer 40 is used to protect the adhesive layer 50 to prevent the adhesive layer 50 from being contaminated before use.

[0061] In this embodiment, the encapsulation layer 10 and the bonding layer 20 are both made of medical PVC material, the indication layer is made of pure water, and the indication layer 30 is directly encapsulated and filled between the encapsulation layer 10 and the bonding layer 20 to form a water bag structure.
