Description

Technical Field

[0001] The invention relates to the field of medical auxiliary technology, and in particular to a surgical drape and a use method thereof. Background Art

[0002] Drapes play a vital role in the operating room. After special disinfection, drapes are sterile, non-irritating, and not prone to allergies. They can effectively isolate external bacteria and dust. During surgery, drapes isolate the exposed parts of the patient from the surgical environment, thereby protecting the surgical area from contamination and reducing the incidence of surgical infection. At the same time, during surgery, the patient is usually naked, and drapes can cover other parts of the patient, reducing the embarrassment of the patient and medical staff and protecting the patient's privacy.

[0003] The drape in the prior art can effectively expose the surgical site, isolate other locations, and reduce the risk of surgical infection. Since the non-surgical site needs to be shielded and isolated, the drape needs to be extended to facilitate shielding of other parts of the patient. However, due to the large size of the drape, in the prior art, multiple people need to work together to complete the laying of the drape, which is time-consuming, labor-intensive, and inconvenient to operate, thereby affecting the efficiency of the operation.

[0004] In summary, how to solve the problem in the prior art that laying a drape requires the cooperation of multiple people to complete the laying of the drape, which is time-consuming and labor-intensive, inconvenient to operate, and thus affects the efficiency of the operation has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a convenient surgical drape and a method for using the same. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a surgical drape and a method for using the same. Through the design of the laying component, the drape can be automatically laid along the patient's surgical position without the need for collaboration of multiple people, and after the operation, the drape can be quickly and conveniently recovered, thereby improving the convenience of using the drape and greatly improving the efficiency of the operation.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a surgical drape, comprising a drape, on which a laying component for laying the drape, a positioning component for positioning the surgical site and a drainage component for absorbing accumulated fluid are provided.

[0007] The laying assembly includes a center rod and a controller, on which a main rotating plate and several auxiliary rotating plates are sequentially mounted from top to bottom; guide rods are fixedly connected to the bottom of the main rotating plate and the auxiliary rotating plates; guide rings for limiting the guide rods are fixedly connected to the side walls of the auxiliary rotating plates; arc-shaped guide grooves are opened on the tops of the auxiliary rotating plates; the guide rods are slidably matched with the guide grooves located at the same horizontal height; one side of the main rotating plate is detachably connected to the laying towel; a driving member is provided on the main rotating plate, and the controller is used to control the operation of the driving member and thereby drive the main rotating plate to rotate around the center rod.

[0008] The technical principles of the above scheme are as follows:

[0009] One side of the drape is glued to the side wall of the main rotating plate, and the other side is glued to one side of the patient's limb; the controller controls the driving member to make the main rotating plate rotate forward, and the main rotating plate drives the auxiliary rotating plate to rotate, so as to unfold the drape along the circumference of the patient's surgical position; after the drape is unfolded, the drape is cut according to the area of ​​the patient's surgical position, and the operation can be performed; after the operation is completed, the controller controls the driving member to make the main rotating plate rotate in the opposite direction, and the drape is folded along the circumference of the patient's surgical position, and the drape can be recovered.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The present invention uses the design of a central rod, a main rotating plate and a secondary rotating plate to bond the two sides of the drape to the side wall of the main rotating plate and one side of the patient's limb respectively, and then utilizes the rotation of the main rotating plate to drive a plurality of secondary rotating plates to rotate around the central rod, thereby driving the drape to be unfolded along the patient's limb to complete the laying of the drape; such a design is simple to operate, does not require the cooperation of multiple people, greatly reduces the manpower consumption and actual consumption in the process of laying the drape, and effectively improves the efficiency of the operation.

[0012] 2. In the prior art, 2-4 persons are often required to lay the drape, and each person pulls one corner of the drape to lay it on the patient's limb. During this process, the drape may fall due to operator error, or may be torn or damaged due to uneven force from all parties. In these cases, the drape needs to be replaced, which greatly affects the operating efficiency. The present invention utilizes a main rotating plate to bond the drape, which effectively prevents the drape from falling, and then utilizes the rotation of the main rotating plate and several auxiliary rotating plates to extend and lay the drape. The controller adjusts the speed of the driving member so that the main rotating plate and several auxiliary rotating plates rotate evenly, thereby making the laying force even, greatly reducing the possibility of tearing or damage of the drape, and further improving the efficiency of drape laying, thereby improving surgical efficiency.

[0013] 3. The present invention adopts the design of the center rod, the main rotating plate and the auxiliary rotating plate. During the operation, the center rod is adjusted to be directly above the patient's surgical position. The main rotating plate and the auxiliary rotating plate rotate around the center rod, so that the drape can be laid with the patient's surgical position as the center, thereby ensuring the laying of the drape at the surgical position and improving the accuracy of drape laying.

[0014] Furthermore, the positioning assembly includes a plurality of slits opened on the drape, the slits are all arc-shaped and form a plurality of positioning holes, and the plurality of positioning holes are all circumferentially arranged to form a plurality of positioning rings with different diameters.

[0015] Beneficial effects: After the drape is laid, the doctor can cut the drape along the positioning rings of different diameters according to the required surgical scope. Due to the design of several seams, the disassembly of the drape is more convenient and simple. The doctor only needs to cut the drape along the seams distributed with the same diameter to obtain the surgical operation space of the required surgical scope.

[0016] During the operation, due to the long operation time, the drape will be in contact with the patient's skin for a long time, which will cause fever and sweating. The seam design can improve the breathability of the drape, thereby avoiding the patient's skin from being in contact with the drape for a long time, which will cause fever and sweating.

[0017] Furthermore, the drainage assembly includes a plurality of drainage tubes and a pump assembly, and the drainage tubes are all slidably connected to the positioning holes; one end of the drainage tubes extends to the surgical site, and the other end is connected to the pump assembly; the controller is used to control the pump assembly to absorb the accumulated fluid.

[0018] Beneficial effects: Before surgery, medical staff can insert the drainage tube into the linearly distributed positioning holes, extend it to the patient's surgical site, quickly install the drainage tube, start the pump assembly, and absorb the accumulated fluid at the patient's surgical site; they can also insert it into the circumferentially distributed positioning holes, extend it to the patient's surgical site in a curved shape, increase the installation length of the drainage tube, and increase the drainage volume. In this process, the positioning holes will fix the drainage tube and improve the stability of the drainage work.

[0019] Furthermore, the side walls of the drainage pipes are fixedly connected with a plurality of adsorption tubes, and the adsorption tubes all pass through the bottom of the drape; the adsorption tubes are all connected with a one-way valve, and the controller is used to control the operation of the one-way valve so as to generate negative pressure in the adsorption tubes.

[0020] Beneficial effects: While utilizing the negative pressure adsorption principle to adsorb the accumulated fluid at the surgical site, negative pressure will also be generated in the adsorption tube by opening the one-way valve through the controller. By fitting the adsorption tube to the patient's skin surface, the drainage tube can be fixed on the patient's skin surface, further improving the working stability of the drainage tube. At the same time, since the drainage tube is inserted into the positioning hole, the drape will also be stably attached to the patient's skin surface, providing the doctor with a good surgical space, thereby effectively improving the efficiency of the operation.

[0021] Furthermore, the surface of the drape is green, and the color of the drape gradually deepens from the periphery to the center.

[0022] Beneficial effects: Green drapes are very friendly to the doctor's eyes. During long operations, doctors need to stare at the surgical area for a long time. Green drapes can play a buffering role and relieve doctors' visual fatigue. Using different depths of green can further relieve doctors' visual fatigue. At the same time, as the diameter of the positioning ring decreases, the drape color becomes darker, thereby increasing the doctor's attention to the surgical location.

[0023] Furthermore, the center rod is hollow in the middle and is coaxially arranged with the positioning ring.

[0024] Beneficial effects: During the drape laying process, when the center rod is aligned with the patient's surgical position, the doctor can observe and calibrate through the middle of the center rod, and then perform preliminary positioning, so that the drape can be laid accurately at the patient's surgical position.

[0025] Furthermore, the adsorption tube is tapered.

[0026] Beneficial effects: The tapered adsorption tube can have better adsorption capacity, thereby improving the fixation effect of the drainage tube and the drape, thereby improving the efficiency of the operation.

[0027] Further, a method for using a surgical drape is provided, based on the surgical drape, comprising the following steps:

[0028] S1, device installation: prepare a set of supporting devices, and use the supporting devices to fix the central rod on the bed so that the central rod is located directly above the patient's surgical position.

[0029] S2, drape laying: glue one side of the drape to the side wall of the main rotating plate, and glue the other side to one side of the patient's limb; use the driving member to make the main rotating plate rotate in the positive direction, and spread the drape circumferentially along the patient's surgical position; according to the area of ​​the patient's surgical position, cut positioning rings of different diameters.

[0030] S3, operation in progress: After the cutting is completed, the pump assembly is started, and the drape is adsorbed on the patient's skin surface using the adsorption tube to start the operation; during the operation, the drainage tube is used to adsorb the accumulated fluid at the patient's surgical site.

[0031] S4, drape recovery: After the operation is completed, the pump assembly is turned off to stop the adsorption of the adsorption tube to the patient's skin, and the main rotating plate is rotated in the opposite direction by the driving member to retract the drape along the circumference of the patient's surgical position; then the drape is removed from the side wall of the main rotating plate.

[0032] S5, postoperative treatment: After the drape is removed, the central rod and the supporting device are disassembled, and the central rod, the main rotating plate and the auxiliary rotating plate are sterilized.

[0033] Furthermore, in S1, the supporting device is a rotating bed support.

[0034] Further, in S5, the sterilization and disinfection methods include ultraviolet disinfection, alcohol disinfection and high temperature disinfection.

[0035] Beneficial effects: The present invention can effectively and quickly lay the drape to the patient's surgical site, and can quickly collect the used drape after the operation to facilitate subsequent waste disposal; and can absorb the accumulated fluid during the operation, greatly optimizing the surgical environment and improving the efficiency of the operation.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is further described in detail through specific implementation methods:

[0045] Embodiment 1:

[0046] like Figure 1-6 As shown, a surgical drape includes a drape 6, on which a laying component for laying the drape 6, a positioning component for positioning the surgical site, and a drainage component for absorbing accumulated fluid are provided.

[0047] like Figure 1-3 As shown, the laying assembly includes a center rod 1 and a controller, and a main rotating plate 2 and a plurality of auxiliary rotating plates 3 are sequentially sleeved on the center rod 1 from top to bottom; guide rods 4 are integrally formed at the bottom of the main rotating plate 2 and the auxiliary rotating plate 3; guide rings 5 ​​for limiting the guide rods 4 are integrally formed on the side walls of the auxiliary rotating plates 3; arc-shaped guide grooves are provided on the tops of the auxiliary rotating plates 3; the guide rods 4 are slidably matched with the guide grooves located at the same horizontal height; one side of the main rotating plate 2 is detachably connected to the laying towel 6; a driving member is provided on the main rotating plate 2, and the controller is used to control the operation of the driving member and thereby drive the main rotating plate 2 to rotate around the center rod 1.

[0048] like Figure 4-5 As shown, the positioning assembly includes a plurality of slits opened on the drape 6, the slits are all arc-shaped and form a plurality of positioning holes 7, and the plurality of positioning holes 7 are all circumferentially arranged to form a plurality of positioning rings of different diameters.

[0049] During the operation, after the drape 6 is laid, the doctor can cut the drape 6 along the positioning rings of different diameters according to the required size of the surgical scope. Due to the design of the multiple seams, the disassembly of the drape 6 is more convenient and simple. The doctor only needs to cut the drape 6 along the seams distributed with the same diameter to obtain the surgical operation space of the required surgical scope.

[0050] During the operation, due to the long operation time, the long-term contact between the drape 6 and the patient's skin will cause fever and sweating. The design of the seam can improve the ventilation effect of the drape 6, thereby preventing the patient's skin from getting hot and sweating due to the long-term contact between the drape 6 and the patient. Before the operation, the medical staff can insert the drainage tube 8 into the linearly distributed positioning holes 7 in a straight line, extend it to the patient's surgical position, quickly install the drainage tube 8, start the pump assembly, and absorb the accumulated fluid at the patient's surgical position; it can also be inserted into the circumferentially distributed positioning holes 7, extend it to the patient's surgical position in a curved shape, increase the installation length of the drainage tube 8, and improve the drainage effect. In this process, the positioning holes 7 will limit and fix the drainage tube 8, and improve the stability of the drainage work. The insertion of the drainage tube 8 can also be prefabricated in advance during manufacturing to further improve work efficiency.

[0051] like Figure 6As shown, the drainage assembly includes a plurality of drainage tubes 8 and a pump assembly. The drainage tubes 8 are slidably matched with the positioning holes 7; one end of the drainage tubes 8 extends to the surgical site, and the other end is connected to the pump assembly; the controller is used to control the pump assembly to absorb the accumulated fluid.

[0052] The side walls of the drainage tube 8 are fixedly bonded and connected with a plurality of adsorption tubes 9, which all pass through the bottom of the drape 6; the adsorption tubes 9 are all connected with a one-way valve, and the controller is used to control the operation of the one-way valve so that the adsorption tubes 9 generate negative pressure to adsorb the patient's skin.

[0053] The specific implementation process is as follows:

[0054] by Figure 1 For example, in this embodiment, the top of the center rod 1 is fixed with bolts using the rotating bed support in the prior art, and rotated to the position just above the patient's surgical site. In this embodiment, the driving member is a belt conveyor, which is bolted and connected to the rotating bed support, and the belt screw of the belt conveyor is fixedly sleeved at the hinge of the main rotating plate 2 and the center rod 1. In this embodiment, the pump assembly is a negative pressure pump.

[0055] During the preoperative preparation, the main rotating plate 2 and all the auxiliary rotating plates 3 are in an overlapped state, and the drape 6 is in a folded state. The medical staff guides the patient to lie flat on the bed, and bonds the two sides of the drape 6 to the bottom of the main rotating plate 2 and one side of the patient's body, respectively. In this embodiment, the drape 6 is bonded by medical adhesive tape.

[0056] like Figure 1 As shown in the figure, after the installation of the drape 6 is completed, the medical staff starts the belt conveyor through the controller, and controls the belt of the belt conveyor to drive the main rotating plate 2 to rotate clockwise around the central rod 1. At this time, the guide rod 4 at the bottom of the main rotating plate 2 slides clockwise along the guide groove located at the same horizontal height as the main rotating plate 2. When the guide rod 4 at the bottom of the main rotating plate 2 slides to contact the guide ring 5 located at the same horizontal height as the main rotating plate 2, the main rotating plate 2 rotates 90° and continues to rotate. The guide rod 4 generates a traction force on the guide ring 5, so that the first auxiliary rotating plate 3 from top to bottom rotates clockwise with the main rotating plate 2. Similarly, the main When the rotating plate 2 rotates to 180°, the second auxiliary rotating plate 3 rotates with the first auxiliary rotating plate 3. When the main rotating plate 2 is pulled to rotate to 270°, the third auxiliary rotating plate 3 rotates with the second rotating plate, so that the main rotating plate 2 and all the auxiliary rotating plates 3 are completely unfolded from an overlapping state to a plane. In this process, since one side of the drape 6 is bonded to the patient's body and the other side is bonded to the main rotating plate 2, the main rotating plate 2 and the auxiliary rotating plates 3 are unfolded with the patient's surgical position as the center. Therefore, the drape 6 will also rotate and unfold with the main rotating plate 2, thereby realizing the laying of the drape 6.

[0057] like Figure 4As shown, after the drape 6 is laid, the doctor cuts it according to the diameter of the surgical site of the patient and the positioning rings of different diameters to obtain the surgical space, which is convenient for the doctor to perform the surgery.

[0058] like Figure 1 As shown, after the operation is completed, the belt conveyor is started by the controller, and the belt of the belt conveyor is controlled to drive the main rotating plate 2 to rotate counterclockwise around the central rod 1. When the guide rod 4 rotates counterclockwise to the side wall of the guide groove at the same height as the guide rod 4, the guide rod 4 will push the guide groove, and then drive each auxiliary rotating plate 3 to rotate counterclockwise in turn. Each auxiliary rotating plate 3 overlaps in turn, and the main rotating plate 2 also rotates back to its original position, driving the drape 6 to be retracted. After the drape 6 is retracted, the operator can remove the drape 6, disinfect the entire device, and replace the drape 6.

[0059] Through the design of the center rod 1, the main rotating plate 2 and the auxiliary rotating plate 3, the two sides of the drape 6 are bonded to the side wall of the main rotating plate 2 and one side of the patient's limb respectively, and then the main rotating plate 2 is rotated to drive several auxiliary rotating plates 3 to rotate around the center rod 1, so that the drape 6 can be driven to unfold along the patient's limb to complete the laying of the drape 6; such a design is simple to operate and does not require the cooperation of multiple people, which greatly reduces the manpower consumption and actual consumption in the laying process of the drape 6, and effectively improves the efficiency of the operation. During the operation, the center rod 1 is adjusted to the top of the patient's surgical position, and the main rotating plate 2 and the auxiliary rotating plate 3 rotate around the center rod 1, so that the drape 6 can be laid with the patient's surgical position as the center, thereby ensuring the laying of the surgical position and improving the accuracy of the laying of the drape 6.

[0060] Compared with the prior art, the prior art often requires 2-4 people to lay the drape 6, each of whom pulls one corner of the drape 6 to lay the drape 6 on the patient's limb. During this process, the drape 6 may occasionally fall due to operator error, or may be torn or damaged due to uneven force from all parties. In these cases, the drape 6 needs to be replaced, which greatly affects the operating efficiency. The present invention utilizes the main rotating plate 2 to bond with the drape 6 to effectively prevent the drape 6 from falling, and then utilizes the rotation of the main rotating plate 2 and several auxiliary rotating plates 3 to extend and lay the drape 6. The speed of the belt conveyor is adjusted by the controller so that the main rotating plate 2 and several auxiliary rotating plates 3 rotate evenly, thereby making the laying force of the main rotating plate 2 and several auxiliary rotating plates 3 even, thereby greatly reducing the possibility of tearing or damage of the drape 6, thereby further improving the laying efficiency of the drape 6 and the surgical efficiency.

[0061] Embodiment 2:

[0062] like Figure 4 As shown, the difference from the above-mentioned embodiment is that the surface of the drape 6 is green, and the color of the drape 6 gradually darkens from the periphery to the center.

[0063] The specific implementation process is as follows: The green drape 6 is very friendly to the doctor's eyes. During a long operation, the doctor needs to stare at the operation area for a long time. The green drape 6 can play a buffering role and relieve the doctor's visual fatigue. Using different depths of green can further relieve the doctor's visual fatigue; at the same time, as the diameter of the positioning ring decreases, the color of the drape 6 becomes darker, thereby increasing the doctor's attention to the operation position.

[0064] Embodiment 3:

[0065] like Figure 1 and Figure 4 As shown, the difference from the above embodiment is that the center rod 1 is hollow in the middle and is coaxially arranged with the positioning ring.

[0066] The specific implementation process is as follows: during the process of laying the drape 6, when aligning the center rod 1 with the patient's surgical position, the doctor can observe and calibrate through the middle of the center rod 1, and then perform preliminary positioning, so that the drape 6 can be accurately laid at the patient's surgical position.

[0067] Embodiment 4:

[0068] like Figure 6 As shown, the difference from the above embodiment is that the adsorption tube 9 is conical.

[0069] The specific implementation process is as follows: the conical adsorption tube 9 can have better adsorption force, thereby improving the fixing effect of the drainage tube 8 and the drape 6, thereby improving the surgical efficiency.

[0070] Embodiment 5:

[0071] like Figure 1-6 As shown, the difference from the above embodiment is that a method for using a surgical drape is performed based on the surgical drape and includes the following steps:

[0072] S1, device installation: prepare a set of supporting devices, and use the supporting devices to fix the central rod 1 on the bed, so that the central rod 1 is located directly above the patient's surgical position. In this embodiment, the supporting device uses a rotating bed support.

[0073] S2, laying of the drape 6: glue one side of the drape 6 to the side wall of the main rotating plate 2, and glue the other side to one side of the patient's limb; use the driving member to make the main rotating plate 2 rotate in the positive direction, and unfold the drape 6 circumferentially along the patient's surgical position; according to the area of ​​the patient's surgical position, cut positioning rings of different diameters.

[0074] S3, operation in progress: after the cutting is completed, the pump assembly is started, and the drape 6 is adsorbed on the patient's skin surface by the adsorption tube 9, and the operation begins; during the operation, the drainage tube 8 is used to adsorb the accumulated fluid at the patient's surgical site.

[0075] S4, drape 6 recovery: after the operation is completed, the pump assembly is turned off, the adsorption tube 9 on the patient's skin is stopped, the main rotating plate 2 is rotated in the opposite direction by the driving member, and the drape 6 is recovered along the circumference of the patient's operation position; then the drape 6 is removed from the side wall of the main rotating plate 2.

[0076] S5, postoperative treatment: After the drape 6 is removed, the central rod 1 is removed from the supporting device, and the central rod 1, the main rotating plate 2 and the auxiliary rotating plate 3 are sterilized. In this embodiment, the sterilization method includes ultraviolet disinfection, alcohol disinfection and high temperature disinfection.

[0077] The specific implementation process is as follows: by rotating the main rotating plate 2, the drape 6 can be effectively and quickly laid to the patient's surgical position, and the used drape 6 can be quickly collected after the operation to facilitate subsequent waste disposal; during the operation, the drainage tube 8 is used to quickly absorb the accumulated fluid, which greatly optimizes the surgical environment and improves the efficiency of the operation; after the operation, the entire device is disinfected to ensure the recycling of the device.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
