Description

Technical Field

[0001] This invention relates to the field of operating tables, and more specifically to a multifunctional puncture device. Background Technology

[0002] Aspiration is an invasive examination procedure and a common medical surgical term. It involves inserting a needle into a body cavity to extract secretions for testing, injecting gas or contrast agents into the body cavity for imaging examinations, or injecting drugs into the body cavity.

[0003] Puncture procedures usually require local anesthesia to reduce pain during the procedure, increase patient compliance and cooperation, and ensure a smooth operation. However, local anesthesia cannot fully cooperate with all patients. For example, children and patients who cannot control themselves may have difficulty cooperating with the procedure, in which case general anesthesia should be chosen.

[0004] However, general anesthesia carries certain risks. Therefore, various puncture tables have been developed for local anesthesia puncture procedures to restrain patients, aiming to increase patient cooperation and prevent physical movement. However, in order to make these puncture tables able to restrain patients of different body types, flexible strips such as woven straps with adjustable length are mostly used to restrain the body. These strips are easy to deform and therefore widely applicable. However, precisely because these flexible strips are easy to deform, their restraint effect on the patient is relatively poor.

[0005] Furthermore, during general anesthesia, patients are unconscious and only have compliance without any cooperation. When the surgical field is poor, medical staff need to use both hands to adjust and maintain the position and angle of the patient's body, which is physically demanding for the medical staff. The puncture table in the relevant technology only has a restraining function and does not have the function of adjusting the position and angle of the patient's body. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional puncture device to solve the following technical problems of existing puncture devices: poor effect in restraining the patient's body, and lack of function in adjusting the position and angle of the patient's body to expand the surgical field.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0008] A multifunctional puncture device includes: a base; a support body that is incompressible and detachably connected to the base, having a shape that can be held by a human body; a support surface formed on one side of the support body and conforming to the front of the human torso; a notch formed on the support body and conforming to the limbs of the human body, the notch being arranged at the position where the limbs contact when the human body holds the support body; and a restraint member detachably connected to the support body and covering each of the notches to form four restraint holes, the restraint member being tightened to make close contact with the limbs of the human body and restrain the limbs of the human body inside the restraint holes.

[0009] Furthermore, the support body has a fitting groove formed around the support body and passing through each of the notches; the restraint is elongated, is circular, or has one end connected to other parts of itself to form a circle, and is embedded in the fitting groove, the fitting groove having a depth that allows the restraint to contact and fit into the human limb inside the notch.

[0010] Furthermore, the support body includes a bracket in the shape of a cross; and four interlocking pieces in the shape of a square, which are respectively assembled at the four corners of the bracket, and the interlocking pieces are fixedly connected to the restraint pieces.

[0011] Furthermore, the bracket includes a first plate and a second plate, both of which are flat and are interlocked perpendicularly to each other.

[0012] Furthermore, both the first plate and the second plate are composed of several sheets of the same shape stacked together.

[0013] Furthermore, in the first plate and the second plate, one of them has a sliding connection structure and the other has a plug-in structure. The splicing member is slidably connected to the sliding connection structure and plugged into the plug-in structure. The direction in which the splicing member slides on the sliding connection structure is the same as the direction in which the splicing member and the plug-in structure are plugged in.

[0014] Further, the base includes: a fixed plate, horizontally arranged and immovable; a movable column connected to the fixed plate, and the movable column being inclined relative to the fixed plate; a movable plate detachably connected to the fixed plate, and the movable plate being inclined relative to the fixed plate; and a support body detachably connected to the movable column and abutting against the top surface of the movable plate.

[0015] Furthermore, a slidable slider is connected to the movable column, a quick-connect interface is formed on the slider, and a quick-connect connector that matches the quick-connect interface is formed on the support body.

[0016] Furthermore, the total length of the human arm is greater than the axial length of the restraint hole corresponding to the upper arm of the human body, which is greater than the length of the upper arm of the human body.

[0017] Furthermore, the axial length of the binding hole corresponding to the human thigh is less than the length of the human thigh.

[0018] The multifunctional puncture device provided in this application has the following advantages compared with the prior art:

[0019] 1. Have the patient hug the support, which restricts the patient's posture into a curled-up position that is not conducive to exerting force. This posture exposes the patient's back and side of the body, providing a good field of vision for the puncture procedure.

[0020] 2. The patient's limbs are inserted into the notches formed in the support, and then restraints are used to restrict the patient's limbs to the support, so that the patient cannot separate from the support on their own. In this position, the patient's forearm, lower leg, hand and foot have no force points and cannot affect their own position. With the help of local anesthesia, the puncture surgery can be performed on patients who are difficult to cooperate.

[0021] 3. The base connecting the support can be selected according to actual needs. By changing the connection method and angle between the support and the base, the angle and position of the patient's body can be changed. Medical staff can select the appropriate base according to the needs of the surgical field so that the patient's body can be maintained in the required position and angle without the assistance of medical staff.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In existing puncture procedures, the binding effect of the braided bandage that restricts the patient's body movement is not ideal. To solve this problem, such as... Figure 1-7 As shown, this application provides an embodiment of a multifunctional puncture device to solve the above-mentioned technical problems.

[0035] Its specific structure includes a base 1, a support body 2, a support surface 21, a notch 22, and a restraint component 3.

[0036] Base 1 is arranged to connect to a fixed building;

[0037] The support 2 is incompressible and detachably connected to the base 1, and has a shape that can be held by a human body;

[0038] The support surface 21 is arranged on one side of the support body 2 and matches the front of the human torso;

[0039] The notch 22 is arranged on the support body 2 and matches the limbs of the human body. The notch 22 is arranged at the position where the limbs can contact when the human body hugs the support body 2 and the front of the torso matches the support surface 21.

[0040] The restraint 3 is detachably connected to the support 2 and covers each notch 22 to form 4 restraint holes 4. When the restraint 3 is tightened, it comes into close contact with the limbs of the human body and restrains the limbs of the human body inside the restraint holes 4.

[0041] The base 1 is fixed to a wall, the ground, or the ceiling, or to an object that is placed on the ground but is extremely heavy and difficult to move.

[0042] Support 2 is a relatively soft but almost incompressible rigid object such as plastic or foam, while restraint 3 is a flexible object such as an airbag, belt, or rope that can stretch and bend.

[0043] Based on the above embodiment, the patient's limbs are passed through the four restraint holes 4, allowing the patient to hug the support body 2. Then, the restraint holes 4 are tightened to bind the patient's limbs so that they cannot be pulled out. The patient's chest, abdomen, upper arms, and thighs firmly hug the support body 2, and the patient's body posture is restrained into a curled-up position, which is suitable for lumbar puncture. At the same time, the patient's forearms, lower legs, hands, and feet have no points of force application and cannot affect their own body position.

[0044] Furthermore, traditional restraint braids are usually connected to the operating table through various joints, buckles, and clamps, which are quite troublesome to assemble, disassemble, and use. In order to simplify the use of restraint component 3, an optional embodiment is provided, the specific structure of which is described below.

[0045] The support body 2 has a fitting groove 25 that surrounds the support body 2 and passes through each notch 22;

[0046] The restraint 3 is elongated, loop-shaped, or has one end connected to other parts of itself to form a loop, and is embedded in a fitting groove 25 having a depth that allows the restraint 3 to contact and fit into the human limbs inside the notch 22.

[0047] The restraint component 3 is an elastic band, which is loop-shaped and can stretch elastically;

[0048] Alternatively, the restraint 3 is a braided strap, one end of which is connected to other parts of itself by a buckle to form a loop with an adjustable diameter;

[0049] The fitting groove 25 is used to restrict the restraint 3 so that it cannot move relative to the support 2 after being tightened, and to make the restraint 3 easily contact the surface of the limbs of the human body embedded in the notch 22.

[0050] The depth of the fitting groove 25 is preferably equal to the depth of the notch 22 to achieve the best limb restraint effect.

[0051] Furthermore, due to the significant differences in patients' body sizes, the support body 2 needs to have different volumes to accommodate patients of different body sizes. The restraint component 3 is fixed to the support body 2 with adhesive. When replacing a support body 2 of different volumes, the restraint component 3 must be replaced as a whole. This forces the puncture department to prepare a large number of support bodies 2 and restraint components 3, occupying a large amount of space inside the department. Therefore, the volume of the support body 2 should be able to shrink and expand. However, under the premise that the support body 2 can shrink and expand, the support body 2 should also be an almost incompressible rigid object to avoid the force of the patient holding it causing it to shrink and change the patient's position.

[0052] To solve the above technical problems, such as Figure 8 As shown, an alternative embodiment is provided, the specific structure of which is described below.

[0053] The support 2 includes a bracket 23 and a splicing component 24.

[0054] The support 23 is cross-shaped;

[0055] The splicing component 24 is square in shape. There are four splicing components 24, which are respectively assembled at the four corners of the bracket 23. The splicing component 24 is fixedly connected to the restraint component 3.

[0056] Based on the above embodiments, for patients of different body types, only the stents 23 with different lengths, widths and thicknesses need to be replaced, without replacing the splicing parts 24, thus saving space.

[0057] The bracket 23 and the splice 24 can be connected by interference fit of holes and columns, or by mortise and tenon joints.

[0058] Furthermore, since the cross-shaped support 23 occupies a large space, and patients of the same height need to choose different widths of support 23 depending on their weight, in order to reduce the number of support 23 and thus reduce its space occupation, an optional embodiment is provided, the specific structure of which is described below.

[0059] The bracket 23 includes a first plate 231 and a second plate 232, both of which are flat and are perpendicularly snapped together.

[0060] In this embodiment, slots 233 are formed on both the first plate 231 and the second plate 232. The slots 233 occupy nearly half the width of the first plate 231 and the second plate 232 respectively, and the first plate 231 and the second plate 232 are connected by the slots 233.

[0061] By disassembling the cross-shaped stent 23 into a flat first plate 231 and a second plate 232, the space required to store the stent 23 can be significantly reduced. Furthermore, combining the first plate 231 and the second plate 232 of different lengths and thicknesses can accommodate patients of different heights and weights.

[0062] Furthermore, since the first plate 231 and the second plate 232, which have different thicknesses, differ only in thickness, they can be further improved to reduce the space they occupy during storage.

[0063] Both the first plate 231 and the second plate 232 are composed of several sheets of the same shape stacked together.

[0064] By stacking different numbers of sheets, first plates 231 and second plates 232 of different thicknesses can be obtained. Furthermore, in order to make the bracket 23 and the splice 24 easy to assemble and not easy to separate, an optional embodiment is provided, the specific structure of which is described below.

[0065] In the first plate 231 and the second plate 232, one of them has a sliding connection structure 234 and the other has a plug-in structure 235. The splicing member 24 is slidably connected to the sliding connection structure 234 and plugged into the plug-in structure 235. The direction in which the splicing member 24 slides on the sliding connection structure 234 is the same as the direction in which the splicing member 24 and the plug-in structure 235 are plugged into.

[0066] Specifically, the sliding connection structure 234 is a dovetail-shaped or T-shaped slide rail, the plug-in structure 235 is a cylindrical plug, and the splice 24 has a sliding groove 241 and a plug hole 242. The sliding groove 241 cooperates with the sliding connection structure 234 so that the splice 24 can only move along the sliding connection structure 234. The plug hole 242 is interference-fitted with the plug-in structure 235 so that the splice 24 is not easy to separate from the bracket 23 along the sliding connection structure 234.

[0067] When the first plate 231 and the second plate 232 are formed by stacking several pieces of the same shape, the sliding connection structure 234 and the plug-in structure 235 are only formed on the two outermost pieces.

[0068] Using splicing piece 24 to connect the first plate 231 and the second plate 232 can also prevent the separation of several pieces forming the first plate 231 and the second plate 232.

[0069] Furthermore:

[0070] In order to enable medical staff to select the patient's position according to actual needs and obtain the best surgical field of vision, the angle of the support body 2 can be selected or adjusted when it is connected to the base 1. Therefore, an optional embodiment is provided, the specific structure of which is described below.

[0071] The base 1 includes a fixed plate 11, a movable column 12, and a movable plate 13.

[0072] The fixed plate 11 is horizontally arranged and cannot be moved;

[0073] The movable column 12 is connected to the fixed plate 11, and the tilt angle between the movable column 12 and the fixed plate 11 can be selected;

[0074] The movable plate 13 is detachably connected to the fixed plate 11, and the tilt angle between the movable plate 13 and the fixed plate 11 can be selected.

[0075] The support 2 is detachably connected to the movable column 12 and abuts against the top surface of the movable plate 13.

[0076] Adjusting the angle of the support column can adjust the position of the patient restrained by the support body 2 and the restraint 3, thereby obtaining a wider surgical field of vision. Other suspended parts of the patient's body can be supported by pillows, blankets, or other items.

[0077] The methods for selecting the angles of the movable column 12 and the movable plate 13 include:

[0078] 1. Replace the movable column 12 and movable plate 13 with different angles. In this embodiment, the fixed plate 11 has a plurality of insertion holes 111, and the movable column 12 and movable plate 13 have corresponding plugs 14. By plugging and unplugging the movable column 12 and movable plate 13 with different tilt angles, the angle between the support body 2 and the fixed plate 11 can be selected.

[0079] 2. Hinge the movable column 12 and the movable plate 13 to the fixed plate 11, and drive the movable column 12 and the movable plate 13 to rotate by a cylinder or motor. Alternatively, the angle between the support body 2 and the fixed plate 11 can be selected, but this embodiment is not shown in the figure.

[0080] Furthermore, in order to facilitate the connection between the movable column 12 and the support 2 and reduce the patient's waiting time for surgery, an optional embodiment is provided, the specific structure of which is described below.

[0081] A sliding slider 15 is connected to the movable column 12. A quick-connect interface 151 is formed on the slider 15. A quick-connect connector 26 that matches the quick-connect interface 151 is formed on the support body 2.

[0082] The column is an aluminum alloy guide rail, the slider is an H-shaped slider, and the quick-connect connector 26 is a long strip in the shape of a dovetail or a T.

[0083] Based on the above embodiments, medical staff can push the support 2 closer to the slide bar, and then slide the slider down to allow the quick-connect interface 151 to be inserted into the quick-connect connector 26 to complete the connection between the base 1 and the support 2.

[0084] The patient has no leverage point that could separate the slider and the bracket 23, so the connection is secure and easy to assemble and disassemble.

[0085] Furthermore, since the lumbar puncture site is on the back of the body, the support 2 can only be connected to the slider 15 via the quick-connect connector 26 on its front side. To prevent the patient from attempting to disconnect the quick-connect connector 26 from the slider 15, an alternative embodiment is provided, the specific structure of which is described below.

[0086] The total length of the human arm is greater than the axial length of the restraint hole 4 corresponding to the upper arm of the human body, which is greater than the length of the upper arm of the human body.

[0087] Based on the above embodiments, the patient's forearm is also restrained by the restraint hole 4, leaving only the part below the wrist free to move, making it difficult for the patient to reach the slider 15.

[0088] Furthermore, since the human leg muscles are relatively strong, if the thighs and calves are bound at the same time, when the patient curls up their legs, they are likely to push the support 2 towards their head through their knees, causing a change in the position between the patient and the support 2. Therefore, an optional embodiment is provided, the specific structure of which is described below.

[0089] The axial length of the binding hole 4 corresponding to the human thigh is less than the length of the human thigh.

[0090] Based on the above embodiment, the patient's knee is exposed outside the restraint hole 4, the patient's lower leg can move freely and cannot exert force on the support 2 through its knee.

[0091] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of the embodiments of the present invention.
