Description

Technical Field

[0001] The invention belongs to the technical field of protective pads, in particular to a protective pad for a hand holding a gastroenteroscopic instrument. Background Art

[0002] Gastrointestinal endoscopy and treatment are important means of diagnosing and treating digestive system diseases. During the operation of gastrointestinal endoscopy, doctors need to hold the operating handle of the gastrointestinal endoscopy instrument for a long time. Due to the complexity and long duration of the operation, the doctor's hands will be under great pressure and friction. When performing complex endoscopic surgery, the operation time may be as long as several hours. The doctor's hand base, back of the hand and other parts will be compressed due to close contact with the operating handle and frequent movements, causing hand fatigue and pain, and may even cause poor blood circulation in the local skin and tissues, redness and swelling, etc. These problems will not only affect the doctor's comfort in operation, but long-term accumulation may also damage the doctor's hand health, thereby affecting the accuracy and efficiency of the operation.

[0003] At present, in the field of gastroenterological endoscopy, measures for protecting doctors' hands are relatively limited. Ordinary gloves are usually used to provide basic isolation, but ordinary gloves can hardly effectively alleviate the pressure and friction problems between the hands and the operating handles.

[0004] Therefore, those skilled in the art have proposed a protective pad for the hand holding of a gastroenteroscopic instrument to solve the problems raised by the background art. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a gastroenteroscopic instrument operating hand grip protection pad to solve the problem that conventional protection measures in the prior art are difficult to effectively alleviate the pressure and friction between the hand and the operating handle.

[0006] A hand grip protection pad for operating a gastroenteroscopic instrument, comprising: a protection pad body, which comprises a back of hand protection portion, a base of thumb protection portion and an extension portion, wherein the side wall of the back of hand protection portion is connected to the base of thumb protection portion, the base of thumb protection portion is an arc-shaped layer structure, and the extension portion is connected to the bottom surface of the base of thumb protection portion;

[0007] The connecting assembly comprises a first connecting sleeve and a second connecting sleeve, wherein the first connecting sleeve and the second connecting sleeve are both in a "U"-shaped layer structure, and the first connecting sleeve and the second connecting sleeve are symmetrically connected to the side edge of the tiger's mouth protection part.

[0008] Preferably, a rounded corner is formed between the base protection portion and the first connecting sleeve and the second connecting sleeve.

[0009] Preferably, a first positioning belt is connected to the bottom side of the first connecting sleeve, and the first positioning belt is in contact with the outer side of the first connecting sleeve. A second positioning belt is connected to the bottom side of the second connecting sleeve, and the second positioning belt is in contact with the outer side of the second connecting sleeve.

[0010] Preferably, a first fitting portion is provided on the inner side of the first positioning belt, and a second fitting portion is provided on the outer side of the first connecting sleeve, and the first fitting portion and the second fitting portion are fitted to each other.

[0011] Preferably, a third fitting portion is provided on the inner side of the second positioning belt, and a fourth fitting portion is provided on the outer side of the second connecting sleeve, and the third fitting portion and the fourth fitting portion are fitted to each other.

[0012] Preferably, the protection pad body and the connecting assembly both adopt a protective layer.

[0013] Preferably, the protective layer comprises a buffer support layer, an absorbent cotton layer and a non-woven fabric layer;

[0014] The absorbent cotton layers are respectively arranged on the upper surface and the bottom surface of the buffer support layer, and the non-woven fabric layer is arranged on the surface of the absorbent cotton layer.

[0015] Preferably, the buffer support layer is made of sponge material.

[0016] Preferably, the buffer support layer is made of polyurethane sponge.

[0017] Preferably, the buffer support layer is made of calcium alginate sponge.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a back-of-the-hand protection portion, a base-of-the-palm protection portion, an extension portion and a connecting component, so that the protection pad can fit tightly against the base-of-the-palm when worn. When the operating handle is pressed down, it effectively alleviates blood circulation disorders in the local skin and tissues of the hand caused by excessive local pressure. Under long-term operation, the base-of-the-palm can also be continuously and stably protected, reducing the risk of skin wear and alleviating joint pressure. The protection pad can be firmly fitted to the hand through the connecting component to prevent deviation caused by the downward pressing action of the handle or other movements of the hand during operation, thereby avoiding abnormal wear of the base-of-the-palm due to sliding of the protection pad.

[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 2 As shown: The present invention provides a gastroenteroscopic instrument operation hand grip protection pad, comprising: a protection pad body 1, which includes a back of hand protection part 101, a base of the thumb protection part 102 and an extension part 103, the side wall of the back of hand protection part 101 is connected to the base of the thumb protection part 102, the base of the thumb protection part 102 is an arc-shaped layer structure, and the extension part 103 is connected to the bottom surface of the base of the thumb protection part 102, and the back of hand protection part 101, the base of the thumb protection part 102 and the extension part 103 are based on the force and contact conditions of the human hand when holding the gastroenteroscopic instrument operating handle; the back of hand protection part 101 is used to prevent direct friction and pressure between the operating handle and the back of the hand, and reduce the wear of the back of the hand skin; the base of the thumb protection part 102 is an arc-shaped layer structure, the shape of which matches the physiological curvature of the base of the thumb, can fit the base of the thumb tightly, and effectively disperse the pressure on the base of the thumb during operation; the extension part 103 is connected to the bottom surface of the base of the thumb protection part 102, which increases the contact area between the protection pad and the operating handle, improves the stability, and further ensures that the protection pad is not easy to shift during operation;

[0030] The connecting component 2 includes a first connecting sleeve 201 and a second connecting sleeve 202. The first connecting sleeve 201 and the second connecting sleeve 202 are both in a "U"-shaped layer structure, and the first connecting sleeve 201 and the second connecting sleeve 202 are symmetrically connected to the side edges of the tiger's mouth protection part 102. The first connecting sleeve 201 is sleeved on the thumb position, and the second connecting sleeve 202 is sleeved on the index finger position. When the thumb and index finger hold the operating handle, the "U"-shaped structure can adapt to the shape of the thumb and index finger and wrap them from both sides, so that the protection pad can be firmly combined with the hand and support the operating handle, which can effectively prevent the protection pad from sliding or rotating due to hand movements during operation, ensuring that the protection pad is always in a stable holding position during operation.

[0031] As attached Figure 4 As shown: a rounded portion 104 is formed between the base protection portion 102 and the first connecting sleeve 201 and the second connecting sleeve 202. The rounded portion 104 reduces the sharp transition between the connecting sleeves. During operation, when the thumb and index finger move, discomfort or damage to the doctor's hand caused by sharp edges can be avoided. Especially during long-term operation, the pressure and friction on the hand skin are reduced, ensuring the comfort of operation.

[0032] As attached Figure 3-6 As shown: the first connecting sleeve 201 is connected to the bottom side with the first positioning belt 3, and the first positioning belt 3 is in contact with the outer side of the first connecting sleeve 201; the second connecting sleeve 202 is connected to the bottom side with the second positioning belt 4, and the second positioning belt 4 is in contact with the outer side of the second connecting sleeve 202.

[0033] A first fitting portion 301 is provided inside the first positioning belt 3, and a second fitting portion 302 is provided outside the first connecting sleeve 201. The first fitting portion 301 and the second fitting portion 302 fit each other. The first positioning belt 3 can be tightly sleeved around the first connecting sleeve 201 through the first fitting portion 301 and the second fitting portion 302.

[0034] A third fitting portion 401 is provided on the inner side of the second positioning band 4, and a fourth fitting portion 402 is provided on the outer side of the second connecting sleeve 202, and the third fitting portion 401 and the fourth fitting portion 402 fit each other; the second positioning band 4 can be tightly sleeved around the second connecting sleeve 202 through the third fitting portion 401 and the fourth fitting portion 402; the tightness of the connection between the protection pad and the fingers is further enhanced by fitting each other, and when the doctor operates the gastroenteroscope, the hand moves to ensure that the first connecting sleeve 201 and the second connecting sleeve 202 are stably fixed on the thumb and the index finger respectively, to prevent the protection pad from loosening due to frequent movements of the hand, thereby ensuring that the protection pad continuously and effectively protects the hand.

[0035] Since the protective pad is stably mounted on the thumb and index finger through the first connecting sleeve 201 and the second connecting sleeve 202, it will not shift during the operation, thereby improving the accuracy of the operation, especially when performing some delicate endoscopic operations, such as endoscopic hemostasis, polypectomy, ESD, ERCP, etc., the doctor can control the operating handle more accurately; the thumb and index finger can apply force and adjust the operating angle more stably, thereby improving the success rate of the operation; at the same time, it reduces hand fatigue and discomfort, especially the fatigue of the thumb and index finger during operation.

[0036] Doctors can maintain a better state during the operation. Compared with not using a protective pad, the onset of hand fatigue will be delayed and the degree will be reduced, thereby maintaining a high operating efficiency throughout the operation, reducing operational errors caused by hand fatigue, and improving the quality of gastrointestinal endoscopic operations.

[0037] As attached Figure 3 As shown: the protective pad body 1 and the connecting component 2 both use a protective layer 5; the protective layer 5 includes a buffer support layer 503, a cotton wool layer 502 and a non-woven fabric layer 501; the cotton wool layer 502 is respectively arranged on the upper surface and the bottom surface of the buffer support layer 503, and the non-woven fabric layer 501 is arranged on the surface of the cotton wool layer 502.

[0038] The buffer support layer 503 is made of sponge material. The buffer support layer 503 is made of polyurethane sponge material. The non-woven fabric layer 501 is located at the outermost layer and has the characteristics of softness and breathability. During use, the non-woven fabric layer 501 is in direct contact with the doctor's hand skin, and can provide a comfortable touch at the back of the hand, the base of the thumb, the thumb and the index finger. The breathability can ensure that the hand skin remains dry during long-term operation, avoiding discomfort caused by stuffiness and humidity.

[0039] The absorbent cotton layer 502 is soft in texture, which increases the overall softness of the protective pad and improves comfort. For the thumb and index finger, it can better fit the finger shape, making the doctor feel more comfortable during the operation. At the same time, the absorbent cotton has a certain water absorption. During the operation, the doctor's hands sweat, and the absorbent cotton layer 502 can absorb sweat to keep the hands dry, preventing discomfort and possible bacterial growth caused by sweat accumulation, especially in the thumb and index finger, which are prone to sweating, and can effectively keep them dry.

[0040] The buffer support layer 503 is made of polyurethane sponge, which is a polymer material with a porous structure. It can effectively disperse pressure and play a buffering role. When impacted by external force, it can disperse the force to each pore to reduce the direct pressure on the wound site. At the same time, it also has a certain elastic recovery ability and can return to its original state after the pressure is removed, continuing to play a buffering and protective function.

[0041] During the operation, the gastroenteroscope operating handle will exert a certain amount of pressure on the hand joints, especially the thumb and index finger joints and wrist joints. The protective pad disperses the pressure through the buffer support layer 503, reduces the force on the joints, and helps prevent long-term cumulative joint injuries such as joint strain and arthritis. This is crucial to the long-term hand health of doctors, prolongs the healthy life of doctors' hand joints, and ensures that doctors can perform gastroenteroscope operations continuously and stably.

[0042] Some hospitals may try to use some temporary cushioning materials, but these materials are often not specially designed for gastroenterological endoscopic operations, and have problems such as poor fit, easy displacement, and unsatisfactory cushioning effect. They cannot meet the special needs of hand protection during gastroenterological endoscopic operations.

[0043] As can be seen from the above, before the operation, the doctor puts the first connecting sleeve 201 of the protective pad on the thumb, and the second connecting sleeve 202 on the index finger, and then fits the first fitting portion 301 with the second fitting portion 302, and the third fitting portion 401 with the fourth fitting portion 402, so that the protective pad is firmly worn on the hand; at this time, the back of the hand protection portion 101, the base of the thumb protection portion 102 and the extension portion 103 fit tightly and comfortably with the doctor's hand holding part, without any foreign body sensation;

[0044] During the operation, the doctor's fingers need to frequently operate the operating part of the gastroenteroscope handle to change the direction and angle. Since the connecting component 2 of the protective pad is firmly fixed on the thumb and index finger, the protective pad does not slide or rotate; the back of the hand protection part 101 effectively blocks the friction between the operating handle and the back of the hand, so that the skin on the back of the hand is not damaged; the tiger's mouth protection part 102 fits the tiger's mouth tightly, and its arc structure and the polyurethane sponge material of the buffer support layer 503 play a role in dispersing the pressure transmitted from the operating handle to the tiger's mouth. Even in the case of long-term holding and operation, there is no redness, swelling or pain at the tiger's mouth.

[0045] For the thumb and index finger, the "U"-shaped structure of the first connecting sleeve 201 and the second connecting sleeve 202 not only adapts to the shape of the fingers, but also the buffer support layer 503 disperses the pressure on the fingers through its porous structure during operation; at the same time, the non-woven fabric layer 501 keeps the hands dry, and the doctor's hands do not sweat due to the heat during the operation; the absorbent cotton layer 502 absorbs a small amount of sweat seeping from the hands, keeps the hands clean and dry, and prevents bacterial growth and hand discomfort that may be caused by sweat accumulation.

[0046] After the operation was completed, the doctor removed the protective pad. His hands did not show any fatigue, injury or discomfort caused by long-term operation of the handle of the gastroenteroscope, and the skin on his hands was in good condition, which enabled the doctor to recover quickly in subsequent work and prepare for the next diagnosis and treatment operation.

[0047] This protective pad effectively reduces the pressure and friction of the gastroenteroscope operating handle on the base of the hand, the back of the hand, the thumb and the index finger. This protection is particularly important for the thumb and index finger, which are in direct contact with the operating handle and frequently apply force. It can prevent skin redness, swelling, abrasions and other injuries in these parts caused by long-term operation, reduce the discomfort of the doctor's hands, especially in complex and long-term gastroenteroscope examinations or surgical operations, and greatly improve the comfort of the doctor's hands.

[0048] Holding the operating handle for a long time may cause adverse effects on the hand joints, such as joint strain. This protective pad disperses the pressure and reduces the force on the joints. It has a significant protective effect on the thumb and index finger joints. This protective pad helps to protect the health of the hand joints, reduces the risk of joint diseases caused by operation, and ensures that the doctor's hand joints can maintain a good condition during long-term work.

[0049] Embodiment 2: As shown in the attached Figure 3 As shown: This embodiment is basically the same as the previous embodiment, except that the buffer support layer 503 is made of calcium alginate sponge, which has good water absorption and buffering properties; it is soft and can be deformed appropriately according to the force conditions. It can fit irregular shapes more stably, and under the action of external pressure, the buffer protects the hand from further mechanical damage.

[0050] Calcium alginate sponge has good water absorption. During the gastroenteroscopy operation, the doctor's hands may sweat, especially during long-term or stressful operations. This water absorption advantage enables calcium alginate sponge to better absorb hand sweat and keep the hands dry.

[0051] It can also deform appropriately according to the force conditions, and can fit more stably to irregular-shaped objects such as the hand. During gastrointestinal endoscopy, the hand's posture and force are constantly changing when holding the operating handle. Calcium alginate sponge can better adapt to these changes and fit closely to various parts of the hand, including the back of the hand, the base of the thumb, the thumb and the index finger. It can better adapt to the force and movement of the hand in the special environment of gastrointestinal endoscopy, and provide more comprehensive and effective protection for the doctor's hands. The deformation ability of polyurethane sponge is relatively weak, and it may not always maintain a perfect fit with the hand when faced with complex hand movements and force changes.

[0052] Embodiment 3: The hand sizes of different doctors are different. In order to achieve the best protection effect, the protective pad can be adjusted. If the doctor's hands are large, the back of the hand protection part 101 and the base of the thumb protection part 102 of the protective pad can be stretched appropriately so that they can better cover the corresponding hand area; for doctors with smaller hands, the first positioning belt 3 and the second positioning belt 4 can be slightly tightened so that the first connecting sleeve 201 and the second connecting sleeve 202 fit the thumb and index finger more closely, and the position of the extension part 103 can be adjusted to keep it stable on the operating handle; through these personalized adjustments, the protective pad can better adapt to the hand characteristics of different doctors, improving the comfort and protection effect of use.

[0053] In some special medical environments, such as when higher hygiene standards are required or when cross infection is to be prevented, the gastroenteroscopic instrument operating hand grip protective pad can be used in conjunction with medical gloves; put on the protective pad first, and then put on the medical gloves. The advantage of this is that the protective pad can continue to play its role of buffering and protecting the hands inside the gloves, while the gloves provide additional isolation protection. After the operation is completed, take off the gloves first, then disinfect the protective pad or directly change the gloves for the next operation to ensure the safety and hygiene of the medical operation.
