Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a surgical intervention glove and a hand model. Background Art

[0002] Natural latex gloves have high strength and good flexibility, elasticity, and comfort. They can isolate viruses and bacteria and protect medical staff. Due to the special nature of surgery, doctors in the interventional department must face a large amount of X-rays every day. Therefore, the gloves worn by interventional doctors during surgery must not only have the function of isolating viruses and bacteria, but also have the function of protecting against X-rays.

[0003] The thickness of medical interventional gloves requires that the average thickness of a single layer is ≥0.3mm to meet the requirements of the national standard "Radiological Diagnostic Protection Requirements GBZ130-2020 (Lead Equivalent is ≥0.025)", and interventional doctors generally need to perform delicate operations during surgery (the minimum thickness of ordinary medical surgical gloves is >0.1mm).

[0004] Currently, the thickness of the fingers, palms and wrists of medical interventional gloves (X-ray protective gloves) are consistent (single-layer thickness is within the range of 0.30-0.35mm). Therefore, when doctors perform surgery, their hands will appear bulky and insensitive when wearing interventional radiation protection gloves, which is inconvenient for doctors to perform surgery. Utility Model Content

[0005] To solve at least one technical problem of the prior art, the present application provides an interventional glove suitable for use by interventional doctors during surgery, which not only retains the comfort of ordinary surgical gloves but also takes into account the radiation protection function, and is very suitable for interventional surgery that requires delicate operations.

[0006] The present application provides a surgical intervention glove, comprising a protective part and an operating part;

[0007] The operating part is arranged on the positions of the surgical intervention glove corresponding to the thumb, index finger and middle finger of the human body;

[0008] The protective portion is the area on the surgical intervention glove except the operating portion.

[0009] Furthermore, the thickness of the operating portion is 0.18-0.22 mm.

[0010] Furthermore, the thickness of the protective portion is 0.31-0.35 mm.

[0011] Furthermore, at the positions of the surgical intervention gloves corresponding to the thumb, index finger and middle finger on the human body, the palm side is the operating part and the back side is the protective part.

[0012] Furthermore, at the positions of the surgical intervention gloves corresponding to the thumb, index finger and middle finger on the human body, the half length close to the palm position is the operating part, and the half length away from the palm position is the protective part.

[0013] In a second aspect, the present application also discloses a hand model for manufacturing the above-mentioned surgical intervention gloves, including an operating surface and a protective surface;

[0014] The operating surface is the outer surface of the hand model corresponding to the operating part of the surgical intervention glove;

[0015] The protective surface is the outer surface of the hand model corresponding to the protective part of the surgical intervention glove;

[0016] The material of the protection surface is rougher than that of the operating surface, or the protection surface is provided with an attached layer which is rougher than that of the operating surface.

[0017] Furthermore, a coating glaze polishing layer is provided on the operating surface.

[0018] Furthermore, a ceramic patterned surface layer is attached to the protective surface.

[0019] Furthermore, the hand model includes two forms: an inspection hand model and a medical hand model;

[0020] The thumb and other fingers of the hand model are on the same plane;

[0021] The thumb of the medical hand model is inwardly closed, so that the finger web plane between the thumb and the index finger is in a vertical relationship with the finger web planes between the other fingers.

[0022] In a third aspect, the present application also discloses a method for manufacturing the above-mentioned surgical intervention gloves using the above-mentioned hand model, comprising step 1: performing preliminary processing on the hand model.

[0023] Furthermore, the method further comprises step 2: immersing the hand model in a coagulant containing calcium ions. Since the protective surface has a stronger calcium ion adsorption capacity than the operating surface, more calcium ions are adsorbed on the protective surface of the hand model than on the operating surface of the hand model in this step.

[0024] Furthermore, the method further comprises step 3: drying the hand mold soaked with calcium ions;

[0025] Furthermore, the method further comprises step 4: immersing the dried hand model into a latex pool. Since more calcium ions are adsorbed on the protective surface of the hand model than on the operating surface of the hand model in step 2, the thickness of the flocculated latex on the protective surface of the hand model in this step is higher than that on the operating surface of the hand model.

[0026] Furthermore, the method also includes step 5: completing the production of the surgical intervention gloves and removing them through post-processing.

[0027] Furthermore, the preliminary treatment includes cleaning and drying the hand mold.

[0028] Furthermore, the post-processing includes curling, drying, leaching, water cooling and demoulding.

[0029] By adopting the above technical solution, the present application has the following beneficial effects:

[0030] The palm surfaces of the thumb, index finger and middle finger produced by the hand model of the present application are relatively thin, which can improve the sensitivity of the fingertips, have better controllability of small tools, and facilitate doctors to perform fine operations. At the same time, the thickness of the back of the fingers is consistent with the thickness of other places, achieving the expected protective effect when doctors perform surgery.

[0044] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0045] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the 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 limiting the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 indirectly connected 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 this application can be understood according to specific circumstances.

[0047] The present application is further explained below in conjunction with specific implementation methods.

[0048] like Figure 1-2As shown, a surgical intervention glove 1 provided in this embodiment includes a protective part 2 and an operating part 3; the operating part 3 is arranged on the surgical intervention glove 1 at positions corresponding to the thumb, index finger and middle finger on the human fingers; the protective part 2 is the area on the surgical intervention glove 1 except the operating part 3. The thickness of the operating part 3 is 0.18-0.22mm. The thickness of the protective part 2 is 0.31-0.35mm. At the positions of the thumb, index finger and middle finger on the human fingers of the surgical intervention glove 1, the palm side is the operating part 3, and the back side is the protective part 2. At the positions of the thumb, index finger and middle finger on the human fingers of the surgical intervention glove 1, the operating part 3 is half the length close to the palm position, and the protective part 2 is half the length away from the palm position.

[0049] When the surgical intervention glove 1 of the present application is in use, the thickness of the protective part 2 is more than 0.3 mm, which can meet the protection function of the doctor's hands during radiological diagnosis under normal circumstances. In addition, the thickness of the operating part 3 is significantly lower than that of the protective part 2, which makes the doctor more flexible when performing surgical operations and can perform delicate operations. In order to maximize the flexibility and protection of the surgical intervention glove 1, the thumb (1 / 2 distance from the root of the finger, excluding the back), index finger (1 / 2 distance from the root of the finger, excluding the back) and middle finger (1 / 2 distance from the root of the finger, excluding the back) of the glove are the operating part 3, and the rest of the part is the protective part 2, so that most areas of the hand can be protected, and the thumb, index finger and middle finger, the three fingers commonly used for operation, are the thinner and more flexible operating parts 3.

[0050] like Figure 8-10 As shown is a further implementation of the present application, a buffer portion 8 is provided between the protective portion 2 and the operating portion 3 of the surgical intervention glove 1. Since the boundary between the protective portion 2 and the operating portion 3 is located at 1 / 2 of the distance from the base of the finger, the corresponding finger here is just near the knuckle. Since the knuckles often need to be bent, and the separation between the protective portion 2 and the operating portion 3 is very clear, stress concentration and breakage are likely to occur between the protective portion 2 and the operating portion 3 during bending. In addition, the large thickness difference will also affect the operator's experience. In order to solve the above problems, the present embodiment further provides a buffer portion 8. The buffer portion 8 is a stepped type (such as Fig. 9 as shown) or uniform buffering (as Fig.10 As shown). By providing the buffer portion 8, the Figure 8 The stress concentration at the boundary between the protective part 2 and the operating part 3 reduces the possibility of damage, and also improves the comfort of use of the surgical intervention glove 1.

[0051] like Figure 3-6As shown, the present application also discloses a hand model for manufacturing the above-mentioned surgical intervention glove 1, including an operating surface 6 and a protective surface 7; the operating surface 6 is the outer surface of the hand model corresponding to the position of the operating part 3 of the surgical intervention glove 1; the protective surface 7 is the outer surface of the hand model corresponding to the position of the protective part 2 of the surgical intervention glove 1; the material of the protective surface 7 is rougher than the material of the operating surface 6, or the protective surface 7 is provided with a rougher attached layer than the attached layer of the operating surface 6, so that the protective surface 7 has a stronger calcium ion adsorption capacity. The material of the operating surface 6 is a coated glaze polished material or a coated glaze polished layer is attached at the position of the operating surface. The material of the protective surface 7 is a ceramic patterned hemp surface material or a ceramic patterned hemp surface layer is attached at the position of the protective surface. The hand model includes two forms: an inspection hand model 4 and a medical hand model 5; the thumb of the inspection hand model 4 is on the same plane with other fingers; the thumb of the medical hand model 5 is inwardly closed, so that the finger web plane between the thumb and the index finger is perpendicular to the finger web plane between the other fingers.

[0052] As a further embodiment of the present application, a buffer surface (not shown in the figure) is also provided on the hand model. The buffer surface can be divided into a stepped buffer surface and a gradient buffer surface. The stepped buffer surface refers to a multi-layer material with different calcium ion adsorption capabilities provided between the protective surface 7 and the operating surface 6. The gradient buffer surface is a ceramic patterned hemp surface material with a gradient pattern density.

[0053] As a further embodiment of the present application, the operating surface 6, the protective surface 7 and the buffer surface are all detachably provided with an additional layer, and the additional layer can be replaced according to the thickness requirements of the glove product.

[0054] As a preferred embodiment of the present application, the roughness Ra of the operating surface 6 is less than 1.2 μm; preferably, the roughness of the operating surface 6 is 0.95 μm. The roughness Ra of the protective surface 7 is in the range of 1.5-4.0 μm, preferably 3.0 μm.

[0055] Ra is the arithmetic mean roughness, which is a common parameter for measuring surface roughness. It is obtained by taking the arithmetic average of the absolute value of the deviation of each point on the profile from the midline within a sampling length. When the Ra value is large, it means that the difference in peak-to-valley height on the surface is large, so the surface is rougher; on the contrary, when the Ra value is small, the difference in peak-to-valley height is small, and the surface is smoother. Therefore, from the perspective of engineering applications, if the surface needs to have a higher smoothness and a lower friction coefficient, a lower Ra value is usually required; in some specific application scenarios, such as when it is necessary to increase friction or increase surface adhesion, a slightly larger Ra value may be selected.

[0056] Therefore, when the Ra value is larger, the surface has a higher calcium ion adsorption capacity when immersed in a coagulant containing calcium ions, and vice versa.

[0057] The roughness of the product during the ceramic material production process can be controlled by controlling the selection and processing of raw materials, molding process, sintering process and finishing treatment, all of which belong to the prior art and are not limited in this application.

[0058] like Figure 7 As shown, the present application also discloses a method for manufacturing the above-mentioned surgical intervention glove 1 by using the above-mentioned hand mold, comprising the following steps:

[0059] Step S1: Preliminary processing of the hand model.

[0060] Step S2: immersing the hand model in a coagulant containing calcium ions. Since the protective surface 7 has a stronger calcium ion adsorption capacity than the operating surface 6, more calcium ions are adsorbed on the protective surface 7 of the hand model than on the operating surface 6 of the hand model in this step.

[0061] Step S3: drying the hand mold soaked with calcium ions;

[0062] Step S4: immersing the dried hand model into a latex pool. Since more calcium ions are adsorbed on the protective surface 7 of the hand model than on the operating surface 6 of the hand model in step 2, the thickness of the flocculated latex on the protective surface 7 of the hand model in this step is higher than that on the operating surface 6 of the hand model;

[0063] Step S5: The surgical intervention glove 1 is manufactured and removed through post-processing.

[0064] As a further embodiment of the present application, the pre-treatment includes cleaning and drying the hand mold, and the post-treatment includes curling, drying, leaching, water cooling and demoulding.

[0065] By adopting the above technical solution, the present application has the following beneficial effects:

[0066] The palm surfaces of the thumb, index finger and middle finger produced by the hand model of the present application are relatively thin, which can improve the sensitivity of the fingertips, have better controllability of small tools, and facilitate doctors to perform fine operations. At the same time, the thickness of the back of the fingers is consistent with the thickness of other places, achieving the expected protective effect when doctors perform surgery.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
