Abstract

The application discloses a radio-positioning glove and belongs to the technical field of medical devices. The glove comprises an elastic inner layer glove and a non-elastic outer layer glove sleeved on the outer side of the inner layer glove, and both of them are made of X-ray non-developing material. The surface of the non-elastic outer layer glove is provided with a surface developing coordinate grid formed by developing material, and physical mark holes penetrating through the outer layer and the inner layer along the thickness direction are arranged at the intersection points of the longitudinal and transverse coordinate lines of the grid.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a radiation positioning glove. Background Technology

[0002] In the diagnosis and treatment of tumors or foreign bodies in the hand, accurate preoperative localization is a key factor in determining the success or failure of the surgery. Due to the delicate anatomy of the hand, the dense distribution of nerves and blood vessels, and the strong sliding and deformability of the skin, traditional localization methods (such as palpation or simple surface marking) often have significant errors.

[0003] While some radiolabeling devices exist in the current technology, most are adhesive or single-layer elastic structures. During wear or hand movements, these devices are prone to geometric deformation due to skin stretching, causing the coordinate information in X-ray images to deviate from the actual anatomical location. This leads to an increased surgical exploration area, increasing the risk of accidental damage to healthy tissue and postoperative recurrence. Summary of the Invention

[0004] To address the problems of low preoperative hand positioning accuracy and easy coordinate system shift due to skin slippage in existing technologies, this invention provides a radial positioning glove designed to achieve millimeter-level precise spatial guidance.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a radiation positioning glove, comprising:

[0006] Elastic inner glove, said elastic inner glove is made of an elastic material that is not visible to X-rays;

[0007] A non-elastic outer glove is worn over the outside of the elastic inner glove. The non-elastic outer glove is made of a non-stretchable material and is not visible on X-rays.

[0008] The surface of the non-elastic outer glove is provided with a surface development coordinate grid formed by X-ray imaging material;

[0009] A through-hole physical marker is provided at the intersection of the longitudinal and transverse coordinate lines of the surface development coordinate grid. The through-hole physical marker penetrates both the non-elastic outer glove and the elastic inner glove along the thickness direction.

[0010] Furthermore, the surface development coordinate grid consists of multiple first development lines and multiple second development lines that intersect the first development lines perpendicularly, with the spacing between two adjacent parallel development lines being 1mm to 5mm.

[0011] Furthermore, the surface development coordinate grid is made of at least one developing material containing barium salt, lead, or metal wire.

[0012] Furthermore, the elastic inner glove is made of medical-grade latex or nitrile rubber.

[0013] Furthermore, the non-elastic outer glove is made of non-stretchable synthetic fiber fabric or medical rigid plastic film.

[0014] Furthermore, the diameter of the through-hole physical marker is in the range of 0.5mm to 2mm.

[0015] Furthermore, the bottom of the elastic inner glove is provided with a cuff for the hand to enter.

[0016] Furthermore, the elastic inner glove and the non-elastic outer glove are connected at the hand insertion end by Velcro, while the remaining parts are overlapped and can slide relative to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention uses a non-elastic outer glove to rigidly constrain the elastic inner glove and the skin underneath by utilizing the non-stretchable physical properties of the material. This achieves the suppression of coordinate system deformation caused by skin slippage during positioning, ensuring the stability of the coordinate grid relative to the lesion.

[0019] 2. This invention achieves the direct conversion of digital coordinates in X-ray images into physical marker points on the patient's body surface by setting physical marker holes that penetrate both layers of gloves at the intersection of the imaging coordinate lines, thus eliminating secondary errors caused by manual conversion.

[0020] 3. By setting an elastic inner glove, the present invention achieves physical isolation between the non-elastic outer glove and the skin. By using the elastic inner glove as a wearing medium, the frictional resistance caused by sweat or dirt on the skin surface is eliminated, thereby enabling the non-elastic outer glove to be worn smoothly without being excessively stretched, and protecting the geometric stability of the outer positioning structure.

[0021] 4. This invention achieves a balance between adaptability and accuracy by nesting an elastic inner glove with a non-elastic outer glove. The elasticity of the inner glove allows for a close fit to hands of different sizes, while the non-elasticity of the outer glove locks in the positioning reference.

[0022] 5. This invention uses X-ray non-radioactive materials to manufacture the glove body and combines them with high-density radioactive materials to manufacture coordinate lines, thereby providing clear millimeter-level measurement references without interfering with the observation of hand bones and lesions.

[0031] Reference Figures 1 to 3 This embodiment provides a radiation positioning glove that, through a nested double-layer structure, provides a stable radiation positioning reference for hand lesions. The device mainly consists of an elastic inner glove 1 and a non-stretchable outer glove 2. The elastic inner glove 1 is made of low-density latex or nitrile rubber, materials that are non-radioactive under X-ray irradiation. The non-stretchable outer glove 2 is made of non-stretchable synthetic fiber fabric or rigid plastic film, and is worn over the elastic inner glove 1. It also possesses X-ray non-radioactive properties to provide a stable geometric reference.

[0032] In actual wearing, the elastic inner glove 1 is first slipped onto the patient's hand, acting as an intermediate insulating layer to separate the non-elastic outer glove 2 from the skin surface. Subsequently, the non-elastic outer glove 2 is slipped onto the outer surface of the elastic inner glove 1. Through the mediating effect of the elastic inner glove 1, a smooth wearing interface is provided for the non-elastic outer glove 2, reducing physical resistance during the slip-on process. This avoids stretching or geometric deformation of the non-elastic material due to uneven stress during wear, maintaining the physical stability of the subsequent positioning coordinates.

[0033] The surface of the non-elastic outer glove 2 is provided with a surface imaging coordinate grid 201 formed of X-ray imaging material. In this embodiment, the surface imaging coordinate grid 201 is made of a high-density material such as barium salt or metal wire, and it consists of two sets of intersecting imaging lines, with a spacing of 1 mm to 5 mm between adjacent parallel lines. At the intersection of the vertical and horizontal coordinate lines of the surface imaging coordinate grid 201, a through-hole physical marker hole 202 with a physical through-hole structure is provided. This through-hole physical marker hole 202 penetrates both the material layers of the non-elastic outer glove 2 and the elastic inner glove 1, forming a physical channel between the external and internal skin surfaces of the device.

[0034] The elastic inner glove 1 has a cuff 101 at its bottom to accommodate hand insertion. The non-elastic outer glove 2 and the elastic inner glove 1 are connected at the cuff 101 via a Velcro structure. Except at this connection point, the remaining parts of the non-elastic outer glove 2 are not fixed to the elastic inner glove 1, existing in a stacked and relatively sliding state. With this structural arrangement, when a slight hand movement causes deformation of the elastic inner glove 1, the non-elastic outer glove 2 can compensate for the slight displacement relative to the inner glove without stretching itself, thereby maintaining the geometry of the surface development coordinate grid 201 and providing a stable reference for image capture.

[0035] During application, the patient wears the device and undergoes an X-ray examination. The projection of the lesion in the image will fall at the corresponding coordinates of the surface imaging coordinate grid 201. Based on the coordinate position determined by the image, the tip of a marker pen is inserted into the skin through the corresponding through-hole physical marker 202, thereby forming a marker point on the skin surface. The non-stretchable nature of the non-elastic outer glove 2 ensures that the marker point and the lesion projection in the image maintain a spatial correspondence, thus providing a positioning reference for the selection of subsequent surgical incisions.

[0036] In summary, the radiation positioning glove provided by this invention establishes a stable surface spatial reference system through the double-layered nesting of an elastic inner glove 1 and a non-elastic outer glove 2. The elastic inner glove 1 not only achieves a precise fit to the human hand but also ensures uniform force distribution during the wearing of the non-elastic outer glove 2 through physical isolation, thereby maintaining the original geometric accuracy of the surface imaging coordinate grid 201. The non-elastic outer glove 2, combining the non-stretchable properties of its material with the physical channel of the through-hole physical marker 202, effectively solves the technical challenge of converting digital image coordinates to the physiological position of the human body, providing millimeter-level visual guidance for surgery and significantly improving the precision of lesion resection.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
