Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an adjustment base fixed to a target object. Background Art

[0002] In the image-guided puncture surgery auxiliary system, there is an auxiliary percutaneous puncture positioning device that is fixed to the human body. This type of product needs to be fixed to the patient when in use, and then CT images are taken together. The computer processes the CT data and adjusts the needle trajectory of the puncture needle. At present, the percutaneous puncture positioning device that is fixed to the human body adopts a direct binding method to the human body, and the device is stably fixed to the human body by filling foam blocks and other methods, such as XACT. Due to the large differences in body shape between different patients and the various body positions of patients during the puncture operation, it is very difficult to fix the device to the human body, which affects the doctor's operating efficiency.

[0003] The method of fixing the device to the human body is generally as follows: install the device on a base (a plate-like component on which the device can be installed), place solid fillers on the human body, place the base on the fillers, select appropriate solid fillers to make the device on the base in a suitable position relative to the human body, and then use straps to tie the human body, the base, and the solid fillers together, thereby fixing the device on the base to the human body.

[0004] However, this fixation method has many shortcomings. For example, due to the different body shapes and body positions of patients, different solid fillers need to be selected and the positions of the solid fillers on the human body are different. The selection and placement of the solid filler are determined by the doctor's naked eye. The doctor usually needs to make continuous attempts (selecting a solid filler and placing it between the base and the human body, and then taking out the solid filler and replacing it with a new solid filler until a suitable solid filler is finally selected) to make a final determination, which takes a long time. At the same time, it is also easy to cause improper positioning of the solid filler and poor patient comfort. Moreover, since the volume of the solid filler is fixed, and different patients have different body shapes and body positions, even if there are solid fillers of various shapes to choose from, it is difficult to adjust the equipment on the base to achieve the ideal posture, and usually the adjustment can only be stopped when it is roughly suitable.

Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0032] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0033] See also Figures 1 to 5 The present embodiment provides an adjustment base fixed to a target object, including a base body 3 and a binding component. The base body 3 has a first surface and a second surface arranged opposite to each other, the first surface is used to connect to an external device, and a plurality of adjustment components are distributed on the second surface. One end of the adjustment component is connected to the base body 3, and the other end is in contact with the target object (shown as a patient's human body 1 in this embodiment), and the distance between the two ends of the adjustment component is adjustable, and the plurality of adjustment components cooperate to adjust the posture of the base body 3 relative to the target object.

[0034] The binding component has two connecting parts, and the two connecting parts are respectively connected to the base body 3 so that the part between the two connecting parts on the binding component cooperates with the base body 3 to form a fixed channel, and the fixed channel is used to be sleeved on the target object. The distance between the two connecting parts on the binding component is adjustable, which is used to adjust the size of the fixed channel to fix the base body 3 on the target object.

[0035] Specifically, the device is fixed to the base body 3, and the device is specifically located on one side of the first surface of the base body 3. The fixed connection method between the device and the base body 3 is not limited, for example, it can be a fastener connection, a snap connection, etc. The base body 3 is provided with corresponding fixing positions, such as some mounting holes when connected by fasteners.

[0036] There are multiple adjustment components on the second surface of the base body 3. By adjusting the multiple adjustment components, the base body 3 can be adjusted to a suitable posture, such as lifting the end close to the head of the human body 1, so that the device fixed on the base body 3 can reach an ideal posture.

[0037] The adjusting component can be a filler with adjustable volume, and the distance between the two ends of the adjusting component can be adjusted by adjusting the volume. More specifically, the filler with adjustable volume can be an airbag 4, and the airbag 4 is connected to the inflation device through an air guide tube 7. One end of the airbag 4 is connected to the base body 3, and the other end is in contact with the human body 1. The volume of the airbag 4 is adjusted by injecting different amounts of gas into the airbag 4, thereby adjusting the distance between the two ends of the airbag 4.

[0038] Furthermore, the airbag 4 may include multiple layers of airbag units in a stacked arrangement, and the interiors of two adjacent airbag units are connected at their stacking locations. One end of the airbag 4 along the stacking direction of the multiple layers of airbag units is connected to the base body 3, and the other end is in contact with the human body 1. The arrangement of stacking multiple layers of airbag units can increase the maximum distance that can be reached between the two ends of the airbag 4. Figure 4 and Figure 5 As shown, in this embodiment, the airbag 4 includes two layers of airbag units, wherein the first layer of airbag units 4 - 1 is close to the base body 3 , and the second layer of airbag units 4 - 2 is close to the human body 1 .

[0039] The airbag 4 can be detachably connected to the base body 3 through the Velcro 9; the air duct 7 can be connected to the airbag unit connected to the base body 3. However, in other embodiments, the airbag 4 can be connected to the base body 3 in other detachable ways, or the airbag 4 can be directly and non-detachably connected to the base body 3; the air duct 7 can also be connected to other airbag units, and the connection between the airbag 4 and the base body 3 and the connection between the air duct 7 and the airbag unit are not limited.

[0040] There are many choices of inflatable equipment, and there is no specific restriction. Preferably, in this embodiment, a hand-held inflatable airbag 8 is used, which is similar to a sphygmomanometer latex ball. In order to distinguish it from the airbag 4 in the adjustment component, the main body of the hand-held inflatable airbag 8 is called a balloon. The main structure of the hand-held inflatable airbag 8 is as follows: a connecting tube is provided on the balloon, and the two ends of the connecting tube are respectively connected to the balloon and the airway 7, and a one-way air valve is provided at the connection between the connecting tube and the balloon, so that only gas is allowed to enter the connecting tube from the balloon; a vent is also provided on the connecting tube, and a vent valve is provided on the vent. When the vent valve is opened, the gas in the balloon 4 can flow out from the vent through the airway 7 and the connecting tube; an air inlet is also provided on the balloon, and a one-way air valve is provided at the air inlet, so that only gas is allowed to enter the balloon from the outside. When it is necessary to inflate the airbag 4, close the deflation valve, squeeze the balloon to allow the gas in the balloon to enter the connecting tube, and then inflate the airbag 4, then release the balloon to allow the external gas to replenish the balloon, and then squeeze the balloon again to inflate the airbag 4. By controlling the number of times and degree of squeezing the balloon, the airbag 4 can be filled with a specified amount of gas. Even if the amount of gas rushing into the airbag 4 is too large, the excess gas can be released through the deflation valve.

[0041] In other embodiments, the adjusting component may also be a component other than the airbag 4, such as a jack-like structure, a telescopic rod structure, etc., and the specific structure of the adjusting component is not limited.

[0042] The binding component includes a cushion 6 and two middle pieces, and the base body 3, one of the middle pieces, the cushion 6 and the other middle piece are sequentially connected to form a fixed channel. The two connecting parts of the binding component are respectively the parts where the two middle pieces are connected to the base body 3. Among them, the distance between at least one of the middle pieces and the two connecting parts of the cushion 6 and the base body 3 is adjustable, and in this embodiment, both are adjustable.

[0043] The middle piece and the cushion 6 are detachably connected by Velcro, and the detachable Velcro connection is also used to adjust the distance between the middle piece and the two connection points between the cushion 6 and the base body 3 by adjusting the sticking positions of the two sticking surfaces of the Velcro in the circumferential direction of the fixed channel. Specifically, the middle piece is provided with a longer Velcro sticking surface arranged along the circumferential direction of the fixed channel, and the distance between the middle piece and the two connection points between the cushion 6 and the base body 3 is adjusted by adjusting the specific position of the longer Velcro sticking surface on the middle piece to stick to the sticking surface on the cushion 6.

[0044] When using, Figure 1As shown, the cushion 6 is placed on the bed 2, the patient lies on the cushion 6, the base body 3 with the device installed is placed on the human body 1, one end of the middle piece is connected to the base body 3, and the other end is preliminarily pasted on the cushion 6. The distance between the two connection points between the middle piece and the cushion 6 and the base body 3 is relatively long, leaving space for the airbag 4 to increase in volume; then the airbag 4 is inflated, the device on the base body 3 is adjusted to a preset position, and finally the end of the middle piece connected to the cushion 6 is removed from the cushion 6 and re-bonded. At this time, the two middle pieces need to cooperate to fix the base on the human body 1 to complete the process of fixing the device to the human body 1 (the fixing process shown in this paragraph is only an example and does not limit the usage of this embodiment. The specific fixing process can be adjusted according to actual conditions).

[0045] Furthermore, the length of the cushion 6, that is, the length along the axial direction of the solid channel, can be set longer (here relative to the base body 3), and the adhesive surface on the cushion 6 is set along the axial direction of the fixed channel, so that the adhesive surface in the middle piece can select the adhesive position according to the position of the base body 3 relative to the cushion 6 in the axial direction of the fixed channel. In this way, when the patient lies on the cushion 6, the position of the patient's body 1 on the cushion 6 does not need to be too precise. After the position of the base body 3 on the human body 1 is determined, the adhesive surface on the middle piece can be pasted to the appropriate position of the adhesive surface on the cushion 6 (if the length of the cushion 6 in the axial direction of the fixed channel is similar to that of the base body 3, then the cushion 6 should be in the corresponding position when the patient lies on the cushion 6).

[0046] Specifically, the middle piece may be some soft and bendable components, such as a strap 5, a cushion, etc. In this embodiment, Figure 1 As shown, each middle piece includes two straps 5, one end of the strap 5 is connected to the base body 3, and the other end is connected to the cushion 6 through Velcro. In other embodiments, the number of straps 5 included in a middle piece is not limited, and can be one or more than two. When there are multiple straps 5, the multiple straps 5 are preferably arranged at intervals along the axial direction of the fixing channel.

[0047] The strap 5 is connected to the cushion 6. When the base body 3 is fixed to the human body 1, the length direction of the strap 5 does not necessarily coincide with the circumference of the fixing channel. Therefore, the connection between the strap 5 and the base body 3 can be set to be a movable connection, specifically through a rotating buckle structure 10 (as shown in the accompanying drawings in this embodiment), a universal hook structure, etc., without specific limitation.

[0048] The present embodiment provides an adjustable base that is solid with the human body. The second surface of the base body 3 has four independently controlled air bags 4 for inflation and deflation. By adjusting the volume of the four air bags 4, the base body 3 can better cover the uneven surface of the human body 1, and the base body 3 can be stably fixed on the surface of the human body 1 in a preset posture. At the same time, the soft surface and variable shape of the air bag 4 can better adapt to the uneven surface of the human body 1 (referring to the surface of the human body 1 is not a plane), providing good comfort for the patient. Moreover, by adjusting the volume of the air bag 4 by holding the corresponding inflatable air bag 8, the height and posture of the base body 3 relative to the human body 1 are adjusted, which is more convenient and quicker than the prior art process of constantly putting in and taking out different solid fillers.

[0049] The present embodiment provides an adjustable base that is solid with the human body, wherein the strap 5 and the cushion 6 are connected by Velcro, and the cushion 6 is provided with a longer adhesive surface along the axial direction of the fixed channel, so that when the patient lies on the bed 2 padded with the cushion 6, the position of the base body 3 on the patient's body surface can be adjusted without moving, thereby making it possible to flexibly adjust the position of the equipment installed on the base body 3.

[0050] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
