Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical products, in particular to a disposable medical surgical film. BACKGROUND

[0002] The surgical film is divided into B1 type, B2 type, C1 type, C2 type, S1 type and S2 type, wherein the B1 type and the B2 type are composed of a film, a pressure-sensitive adhesive and a release paper, the C1 type and the C2 type are additionally provided with a supporting sheet, a collecting bag, a filter screen and a hose on the basis of the B series, and the S1 type and the S2 type are additionally provided with a non-woven fabric on the basis of the B series, and the supporting sheet and the like are optional, and the non-woven fabric has regular and irregular shapes and can be pasted on a surgical site to separate a surgical area from a non-surgical area.

[0003] However, in the prior art, a plurality of instruments such as hemostatic forceps, needle holders and ligature clips need to be used for a long time for minimally invasive surgery, and these instruments can only be temporarily placed on the surface of an operating cloth or the edge of an operating table, and there is no fixed storage position, which not only causes the operating space to be crowded, but also greatly increases the contact frequency of the instruments with the surface and edge of the surgical film and the impact when the instruments accidentally slip during the operation, all of which directly cause additional mechanical interference to the surgical film. In addition, during the operation, the instruments need to be frequently inserted into and taken out of the incision area, and the operation process must be accompanied by direct action on the surgical film. When the instruments are inserted, the friction with the edge of the film body forms a horizontal pulling force, and when the instruments are taken out, the dragging forms a horizontal pulling force. The pressing when the angle of the instruments is adjusted during the operation and the pressing when the instruments are fixed generate a vertical pressure. These external forces are not single and isolated, but the fatigue effect accumulated for a long time still weakens the adhesive force of the film body and destroys the fixed state of the film body. In addition, the edge of the surgical film is in a flat shape and lacks elastic buffering and deformation adaptation ability. During the operation, the cloth is often stretched, wrinkled and deformed due to factors such as patient position adjustment and instrument tray movement. The flat edge of the film body cannot adaptively adjust the deformation of the cloth, the adhesive at the edge first loses effective contact with the fitted surface, and then forms a rolled edge, which destroys the sealing environment of the incision area, increases the risk of contamination, and some medical surgical films have insufficient flexibility of the film body due to the excessive thickness, are difficult to bend and fit complex curved surfaces, and the film body with a hard texture lacks necessary deformation ability and cannot conform to the slight ups and downs of the cloth. Due to factors such as laying method and patient size, the cloth on the surgical area inevitably has local wrinkles, protrusions and the like. The surgical film cannot be closely fitted with the uneven cloth and skin, and a large number of small gaps will be generated between the film body and the fitted surface. These gaps not only destroy the sealing environment of the adhesive and reduce the adhesive stability, but also make the film body unevenly stressed when the external force acts, accelerate the local adhesive failure and easily cause the film body to shift.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Referring to Figures 1-7 , a disposable medical surgical film is provided, comprising a film 1, further comprising a water blocking guide plate 2 arranged on the film 1, a storage device 3 fixedly connected with the water blocking guide plate 2, a storage cover 4 fixedly connected to the surface of the film 1, a plurality of positioning members 5 fixedly connected to the film 1, two thickening sheets 6 fixedly connected to the inner side of the film 1, and two anti-curl units connected with the film 1, the number of the storage cover 4 is at least one, the two thickening sheets 6 and the anti-curl units are symmetrically arranged about the central axis of the film 1, the anti-curl unit comprises a plurality of splicing rods 7 and a combined rod 8 arranged at equal intervals and connected with the film 1, the splicing rod 7 and the combined rod 8 are arranged alternately, the positioning member 5 is located at the four right-angle edges of the film 1, the thickening sheet 6 is located at the bottom of the two sides of the film 1, and the bottom of the film 1 is formed as a whole by splicing the splicing rod 7 and the combined rod 8, and the splicing rod 7 and the combined rod 8 are used to prevent the bottom of the film 1 from being bent.

[0030] Specifically, before the operation, the four positioning members 5 quickly complete the four-corner anchoring of the membrane body, so that the thin film 1 is preliminarily fixed on the skin surface. For the hemostatic forceps, needle holders and other instruments that need to be used for a long time in minimally invasive surgery, the receiving sleeve 4 on the water-blocking guide plate 2 realizes the orderly placement of the instruments through classified limiting, replacing the traditional temporary placement method and relieving the congestion problem of the operation space. During the operation, the stress of the thin film 1 is dispersed to the four corners by the four-corner anchoring structure of the positioning member 5, avoiding the adhesion fatigue caused by the concentrated external force acting on the local part of the membrane body. The thickened sheet 6 at the bottom of the two sides of the thin film 1 forms a local thickening, which improves the wear resistance and compression strength of this part, effectively resisting the local damage caused by instrument friction and dragging, and prolonging the effective fixing time of the membrane body. At the same time, the staggered splicing structure of the splicing rod 7 and the combined rod 8 forms an integrated support at the bottom of the thin film 1, limiting the disordered bending of the membrane body, and giving the membrane body elastic buffering capacity through non-rigid connection. When the surgical drape is stretched or wrinkled due to patient position adjustment or instrument tray movement, the splicing rod 7 and the combined rod 8 can drive the edge of the thin film 1 to adaptively deform, avoiding the problems of adhesive separation and edge rolling caused by the traditional flat edge unable to follow the drape deformation. The flexibility of the splicing structure reinforced thin film 1 makes it better adapt to the local wrinkles, protrusions of the surgical area drape and the complex curved surface of the patient's skin, reducing the small gap between the membrane body and the adherend, ensuring the integrity of the sealed environment, and avoiding the displacement and adhesion failure caused by uneven stress of the membrane body under external force, ensuring the safety and stability of the operation process.

[0031] Referring to Figures 1-3 , the receiving device 3 includes a bag 31 fixedly connected with the water-blocking guide plate 2, a delivery pipe 32 fixedly connected with one end of the bag 31, and a liquid storage sleeve 33 fixedly connected with the other end of the delivery pipe 32. The bag 31 prevents waste tissue fluid from splashing and leaking, and the delivery pipe 32 and the liquid storage sleeve 33 receive impurities, ensuring effective collection and transmission of waste tissue fluid.

[0032] Specifically, the sleeve bag 31 is precisely attached around the peripheral area of the surgical incision, the delivery pipe 32 naturally extends to the side of the operating table, the liquid storage sleeve 33 is fixed at the preset collection position to complete the collection of waste liquid. After the sleeve bag 31 is fixedly connected with the water-blocking guide plate 2, it closely surrounds the periphery of the surgical incision, and the closed structure can effectively block the splashing of waste tissue fluid generated during the operation, avoiding the leakage of waste liquid to the surface of the film 1 or the surgical cloth. It not only prevents the erosion of the adhesive of the film 1 by the waste liquid and ensures the adhesion stability, but also eliminates the pollution of the non-surgical area by the waste liquid and reduces the risk of infection. The waste tissue fluid, micro impurities and the like generated during the operation are guided into the delivery pipe 32 through the sleeve bag 31. The delivery pipe 32 realizes directional transmission of the waste liquid by virtue of its through structure, avoiding the accumulation of waste liquid in the operation area and affecting the operation field of view. The liquid storage sleeve 33 connected to the end of the delivery pipe 32 forms a centralized collection space, ensuring that the waste tissue fluid and impurities transmitted are completely stored, without the need for temporary treatment of waste liquid during the operation, and simplifying the operation process.

[0033] Referring to Figures 1-7 The left and right sides of the water-blocking guide plate 2 are provided with blocking plates 21, and the blocking plates 21 and the water-blocking guide plate 2 are provided with arc blocks 22. The side of the water-blocking guide plate 2 close to the sleeve bag 31 is inclined from the top to the bottom towards the direction close to the sleeve film 101. The water-blocking guide plate 2 is provided with a through slot 201.

[0034] Specifically, the main storage sleeve 4 realizes the classified storage of hemostatic forceps, needle holders and the like. The blocking plates 21 on the left and right sides of the water-blocking guide plate 2 form a horizontal block to liquid. The inclined structure of the side of the water-blocking guide plate 2 close to the sleeve bag 31 guides the waste tissue fluid and micro impurities generated during the operation to converge in the direction of the sleeve bag 31, avoiding the accumulation of waste liquid on the surface of the water-blocking guide plate 2 to form residues. The through slot 201 provided on the water-blocking guide plate 2 provides a quick flow channel for a small amount of leaked waste liquid, so that the waste liquid directly flows into the sleeve bag 31 through the through slot 201, improving the collection efficiency, and on the other hand, the overall weight of the water-blocking guide plate 2 can be reduced, avoiding the concentration of local pressure on the film 1 due to the excessive weight of the water-blocking guide plate 2, and ensuring the adhesion stability of the film body and the attached surface. The inclined design and the through slot 201 work together to cooperate with the closed collection of the sleeve bag 31, the directional transmission of the delivery pipe 32 and the centralized storage of the liquid storage sleeve 33 to solve the problem of waste liquid accumulation affecting the operation field of view.

[0035] The number of storage sleeves 4 is at least one, that is, multiple or one can be set according to different operation needs, and the position thereof also changes with different operations.

[0036] Referring to Figures 2-5A plurality of sleeve films 101 are arranged equidistantly on both sides of the film 1, the number of the splicing rods 7 and the combined rods 8 is equal to the number of the sleeve films 101, the splicing rods 7 and the combined rods 8 are fixedly sleeved in the corresponding sleeve films 101, a surgical port 102 is arranged on the film 1, and the water-blocking guide plate 2 is arranged above the surgical port 102.

[0037] Specifically, the sleeve films 101 on both sides of the film 1 provide fulcrums for the splicing rods 7 and the combined rods 8, because the number of the sleeve films 101 is equal to the sum of the number of the splicing rods 7 and the number of the combined rods 8, each rod can be independently and stably sleeved and fixed through the corresponding sleeve film 101, so that the rod is prevented from being displaced or falling off, the rigidity and elasticity balance of the spliced whole structure is more optimal, when the film 1 is stretched or wrinkled, the cooperative structure of the sleeve film 101 and the rod not only limits the disordered bending of the film 1, but also buffers the deformation stress through the flexibility of the sleeve film 101, and drives the edge of the film 1 to adaptively adjust, so that the film 1 can better adapt to uneven conditions such as cloth wrinkles and skin curves, reduce the fitting gap, and strengthen the sealing effect. The water-blocking guide plate 2 is arranged above the surgical port 102, which does not block the surgical field, and enables the instruments in the storage sleeve 4 to be closely connected with the surgical incision, so that the instruments are more convenient to take and place, the friction and drag of the instruments on the film 1 when entering and exiting are reduced, the stability of the film body is ensured during the whole operation, and the isolation effect is not interrupted.

[0038] Referring to Figures 2-6 The splicing rod 7 comprises an inner sleeve 71 fixedly sleeved in the sleeve film 101, a sliding bar 72 sleeved with the inner sleeve 71, and two splicing bars 73 fixedly connected with the sliding bar 72, the inner sleeve 71 is provided with an inclined groove 711, the sliding bar 72 is fixedly connected with a round convex block 721, the round convex block 721 is located in the inner sleeve 71, one end of the inclined groove 711 is a short-distance horizontal, and the sliding bar 72 is provided with an inner hole.

[0039] The combined rod 8 comprises a shaft sleeve 81 fixedly sleeved in the sleeve film 101, a rotating rod 82 rotationally connected with the shaft sleeve 81, and two combined bars 83 fixedly connected with the rotating rod 82, the diameter of the combined bar 83 is equal to the diameter of the inner hole, and the combined bar 83 enters the inner hole to ensure the insertion adaptability, so that the splicing bar 73 and the combined bar 83 form an integral whole, and after rotation, the lower parts of the two are blocked to the film 1, so that the film 1 is stable at the bottom, and the film 1 can be folded at will during splicing.

[0040] The inner sleeve 71 and the shaft sleeve 81 are fixed to the sleeve film 101 by external gluing, and the splicing rod 7 and the combined rod 8 are both plastic structures, which reduces the cost and weight, and the surfaces of the two are both high-friction treated, so that they will not be displaced when not subjected to external force.

[0041] Specifically, the inner sleeve 71 is fixedly sleeved in the inner part of the sleeve film 101 to form a stable support base, the sliding bar 72 is sleeved with the inner sleeve 71, the circular protrusion 721 fixed on the surface of the sliding bar 72 is precisely embedded in the inclined groove 711 of the inner sleeve 71, one end of the inclined groove 711 is designed as a short horizontal section, the inner hole of the sliding bar 72 provides an adaptive interface for subsequent splicing, the two splicing bars 73 are symmetrically fixed on the sliding bar 72 to constitute a splicing core component, when an external force triggers the sliding bar 72, the circular protrusion 721 moves along the trajectory of the inclined groove 711, guided by the horizontal section of the inclined groove 711, the sliding bar 72 first completes a short horizontal displacement to ensure that the splicing bar 73 is precisely aligned with the combination bar 83 of the combination rod 8, and then the circular protrusion 721 continues to slide along the inclined section of the inclined groove 711, and the sliding bar 72 synchronously generates a rotating action, and the combination bar 83 is inserted into the inner hole of the sliding bar 72 along with the movement of the sliding bar 72, thereby realizing mechanical locking of the splicing rod 7 and the combination rod 8, at this time, the splicing bar 73 and the combination bar 83 form a complete integrated structure, the overall rigidity is improved, and the splicing rod 7 and the combination rod 8 are prevented from being loose or displaced after splicing, the stability of the integrated structure is ensured, and after the splicing bar 73 and the combination bar 83 are rotatably spliced to form a whole, a rigid barrier structure is formed in the lower region of the splicing bar 73 and the combination bar 83, which can effectively limit the disordered deformation of the bottom of the film 1, avoid the bending and displacement of the bottom of the film body due to surgical operation and draping, ensure the stable contact of the film 1 with the fitting surface, and improve the anti-deformation ability.

[0042] Referring to Figures 1-7 The height of the two sides of the thickened sheet 6 is lower than that of the middle part of the thickened sheet 6, so as to avoid the concentration of pressure on the local part of the film 1, and a plurality of triangular protrusions 61 are arranged on the surface of the thickened sheet 6, the top of each triangular protrusion 61 is inclined to the two sides of the bottom, on the one hand, the triangular protrusions 61 increase the contact friction between the thickened sheet 6 and the surgical drape and the skin to prevent the displacement of the bottom of the film 1, and on the other hand, the inclined protrusion structure can decompose the lateral shear force generated during the operation of the instrument and convert it into vertical pressure, thereby further improving the stability of the film body fixation, and meanwhile, the thickening characteristic of the thickened sheet 6 and the protruding structure of the triangular protrusions 61 form a double protection to reduce the risk of film 1 abrasion and tearing, effectively alleviate the external force by dispersing the local pressure and enhancing the contact friction, and ensure the close contact of the film 1 with the fitting surface.

[0043] Referring to Figures 1-7 The positioning member 5 includes a counterweight sleeve 51 fixedly sleeved in the film 1, a plastic sleeve 52 arranged in the counterweight sleeve 51, an elastic strip 53 connected between the counterweight sleeve 51 and the plastic sleeve 52, and a magnetic block 54 installed in the plastic sleeve 52, the film 1 has a stretching space by using the magnetic block 54 to generate fixation through external adsorption and the elastic strip 53 to avoid excessive fixation.

[0044] Specifically, the counterweight sleeve 51 is fixedly sleeved inside the film 1 to form a local structure reinforcing base, the plastic sleeve 52 is nested inside the counterweight sleeve 51, and the two are flexibly connected through the elastic strips 53, which are uniformly distributed to ensure balanced stress. The magnetic blocks 54 are stably installed inside the plastic sleeve 52, which not only fits the installation space of the four corners of the film 1, but also realizes dynamic adaptation through the flexible connection of the elastic strips 53. The magnetic blocks 54 inside the plastic sleeve 52 can generate an attractive force with external magnetic adaptation structures such as operating tables, quickly realizing accurate fixing of the positioning part 5, and then fixing the film 1 flat on the operating area through the anchoring effect of the four right-angle edges, avoiding displacement of the film body during the operation process. The elastic strips 53 between the counterweight sleeve 51 and the plastic sleeve 52 have good stretching and rebounding performance. When the surgical drape is stretched due to body position adjustment or instrument operation, the elastic strips 53 can absorb the tension through deformation to avoid the rigid adsorption of the magnetic blocks 54 causing the film 1 to be excessively pulled, thereby reserving a reasonable stretching space for the film 1 to prevent the film body from tearing or the adhesive from falling off. The rigid structure of the counterweight sleeve 51 can enhance the local strength of the four corners of the film 1 to avoid the film body from being depressed due to the pressure generated by the adsorption of the magnetic blocks 54. The plastic sleeve 52 physically protects the magnetic blocks 54 to prevent local wear caused by direct contact between the magnetic blocks 54 and the film 1. The adsorption type fixing of the magnetic blocks 54 does not require additional binding, and the installation is convenient and reliable in fixing strength, which can quickly complete the positioning and deployment of the film 1. The flexible connection of the elastic strips 53 avoids the limitations of rigid fixing, making the fixing both firm and not rigid, adapting to the dynamic scene in the operation, and enabling the film 1 to better adapt to the slight deformation of the surgical drape, ensuring that the film 1 can remain flat and adhere even if the drape is slightly stretched, avoiding wrinkles in the film body or failure of the adhesive caused by excessive fixation, and protecting the sealing effect of the operating area.

[0045] With reference to Figures 1-7 , the horizontal length of the inclined groove 711 is equal to the sliding distance of the splicing strip 73, and the splicing strip 73 is always in contact with the combined strip 83. The inner sleeves 71 and the shaft sleeves 81 are hollow inside, which not only reduces the weight, but also reduces the local pressure of the rod on the sleeve film 101, avoiding damage to the sleeve film 101 caused by long-term stress, and indirectly ensuring the stability of the fixing basis of the splicing rod 7 and the combined rod 8. The inclined angle of the inclined groove 711 is thirty-five degrees, so that the splicing rod 7 and the combined rod 8 can be stably spliced without causing additional burden to the film 1.

[0046] With reference to Figures 1-7 , the plurality of storage sleeves 4 are uniformly distributed on the left and right sides of the water-blocking guide plate 2. The storage sleeve 4 includes a support plate 41 fixedly connected with the film 1, and a sleeve strip 42 sleeved on the top of the support plate 41, so as to provide hard support for the instrument with the support plate 41.

[0047] The working principle of the present application is as follows: before operation, the rapid positioning and structure strengthening of the film 1 is completed, the positioning piece 5 at the four corners of the film 1 serves as the core anchoring unit, the internal magnetic block 54 is quickly adsorbed with the magnetic structure of the operating table, the counterweight sleeve 51 strengthens the local strength of the four corners of the film 1, avoids the film body from being depressed due to the adsorption pressure of the magnetic block 54, the plastic sleeve 52 protects the magnetic block 54 from local wear and tear, and the elastic strip 53 between the counterweight sleeve 51 and the plastic sleeve 52 reserves reasonable stretching space to avoid rigid adsorption and pulling of the film body. When the sliding slide 72 is operated synchronously, the round convex block 721 first displaces horizontally along the thirty-five-degree inclined chute 711 of the inner sleeve 71 to ensure that the splicing strip 73 and the combined strip 83 of the combined rod 8 are accurately positioned, and then rotates along the inclined section of the chute 711 to insert the combined strip 83 into the inner hole of the sliding slide 72 to form an integrated support, which cooperates with the flexible wrapping of the sleeve film 101 to limit the disordered bending of the bottom of the film 1 and reduce the weight through the hollow design of the inner sleeve 71 and the shaft sleeve 81 to avoid pressing the sleeve film 101. At the same time, the water-blocking guide plate 2 is accurately installed above the surgical port 102 of the film 1, the through slot 201 is completely coincided with the surgical port 102, and the left and right side blocking plates 21 are flexibly connected with the water-blocking guide plate 2 through the arc blocks 22 to preset the waste liquid blocking and flow guiding basis. During the operation, the inclined structure on the side close to the bag 31 of the water-blocking guide plate 2 cooperates with the through slot 201 to quickly guide the waste tissue fluid and small impurities generated during the operation to the bag 31 of the storage device 3, the blocking plate 21 horizontally blocks the waste liquid side overflow, and the arc block 22 buffers the impact force generated by the instrument collision. The bag 31 closely surrounds the surgical incision, the closed structure blocks the waste liquid splashing and leakage, avoids eroding the adhesive of the film 1, and the waste liquid is directionally transmitted to the liquid storage sleeve 33 on the side of the operating table through the conveying pipe 32 to realize centralized collection and prevent the waste liquid from accumulating to affect the operation field of view. The evenly distributed storage sleeves 4 on both sides of the water-blocking guide plate 2 provide rigid support through the support plates 41, the sleeve strips 42 are suitable for hemostatic forceps, needle holders and other different instruments for classified storage to replace the traditional temporary placement and significantly relieve the crowded operation space. At the same time, the thickening piece 6 at the bottom of both sides of the film 1 plays a protective role, the structure of high in the middle and low on both sides disperses the local pressure, the surface triangular convex piece 61 is inclined designed to increase the friction with the cloth and skin to prevent displacement and decompose the lateral shear force generated by the instrument operation into vertical pressure, and the thickening characteristics double reduce the risk of film body abrasion and tearing. When the patient's body position is adjusted or the cloth is stretched, the elastic strip 53 of the positioning piece 5 absorbs the pulling force through deformation to avoid the film 1 from being excessively pulled, the non-rigid splicing structure of the splicing rod 7 and the combined rod 8 drives the edge of the film 1 to adaptively deform through the sliding cooperation of the round convex block 721 and the inclined chute 711, the surgical port 102 of the film 1 is accurately coincided with the through slot 201 of the water-blocking guide plate 2 to reduce the friction and dragging of the film body when the instrument is in and out, and the flexible wrapping of the sleeve film 101 makes the film 1 conform to the skin curved surface and the cloth wrinkles to reduce the fitting gap.

[0048] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application.
