Description

Technical Field

[0001] The invention relates to the technical field of surgical auxiliary instruments, in particular to a multifunctional surgical auxiliary towel. Background Art

[0002] In today's medical surgeries, surgical towels, as a commonly used medical supply, play a vital role. However, traditional surgical towels have many disadvantages: 1. Traditional surgical towels often only have a simple covering function and cannot meet the diverse needs during surgery. For example, during surgery, medical staff may need additional devices to fix the patient's body part, or need special tools to absorb the fluid overflowing from the wound, which makes the surgical operation cumbersome and may affect the efficiency of the operation; 2. During the operation, slight movements of the patient's body or limbs or some inadvertent touches from the outside world may cause the traditional surgical towel to shift or offset, which may not only affect the surgical field of view, but also increase the risk of contamination of the surgical area, causing unnecessary trouble to the operation, and even affecting the smooth progress of the operation. For example, when the patient is under partial or general anesthesia, the patient's limbs or body still need to be restricted to avoid nerve reactions or accidental touches by medical staff during the operation. This causes the patient's limbs or body to shift or deviate, thereby affecting the accuracy of the operation. At the same time, when medical staff swing or lift the patient's body or limbs to expose the surgical field of view, in order to avoid affecting the patient's position, it is necessary to fix the patient's limbs by a bracket or clamp arm. The surgical towel in the prior art lacks the function or structure to limit the patient's body or limbs, so that medical staff need to manually suppress the patient's limbs or limit the patient's limbs by instruments such as elastic bands. This instrument is easy to affect the medical staff's position and surgical field of view; 3. During the operation, fluid will overflow from the patient's wound. Traditional surgical towels lack effective measures to deal with fluid accumulation. Fluid is easy to accumulate on the towel and then penetrate into the surgical area, causing pollution, posing a potential threat to the patient's health. At the same time, the accumulated fluid will remain on the surgical towel and cause erosion or infection to other parts of the patient. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a multifunctional surgical auxiliary towel to solve the problems that traditional surgical auxiliary towels have single functions, cannot restrict the patient's limbs and torso during surgery, and are prone to contamination caused by fluid accumulation during surgery.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a multifunctional surgical auxiliary towel, including a pad towel for laying on an external surgical bed and a cover towel for covering the body surface of an external patient, the pad towel and the cover towel are connected on one side, and a limiting towel is arranged on the top wall of the pad towel along the direction of the edge of the pad towel, and the inner circumferential wall of the limiting towel and the top wall of the pad towel are combined to form a groove for partially accommodating the body of an external patient, and the limiting towel is provided with an interface component for deforming the limiting towel when the external patient lies on the pad towel, and the inner circumferential wall of the limiting towel is gathered toward the patient's body and the groove is reduced, and a contact piece for cooperating with the interface component to make the inner circumferential wall of the limiting towel contact with the body of the external patient, and the limiting towel is provided with an absorbent piece for absorbing liquid overflowing from the patient's wound during surgery.

[0005] The benefits of adopting the above technical solution are: the medical staff lays the pad flat on the operating bed, ensures that the pad is positioned accurately and the side connected to the cover towel faces the appropriate direction for subsequent operations, and appropriately adjusts the initial state of the limiting towel in advance according to the patient's surgical site and body characteristics to ensure that the size and position of the groove can roughly adapt to the part of the patient's body that needs to be fixed. At this time, the interface component is in an unactivated state, the limiting towel maintains its initial shape, and the groove is a preset larger space. With the assistance of the medical staff, the patient lies on the operating bed with the pad laid, so that the part of the body that needs surgery is placed above the groove of the limiting towel. Then the medical staff activates the interface component, and the interface component starts to work, causing the limiting towel to deform. As the interface component operates, the inner circumferential wall of the limiting towel gradually gathers toward the patient's body, the groove shrinks accordingly, and the inner circumferential wall of the limiting towel is moved. During the gathering process, the abutment piece contacts and gradually fits with the surface of the patient's body, and finally the abutment piece abuts against the patient's body to achieve stable fixation of the patient's body part. At this time, the patient's body is stably fixed on the pad, and the surgical towel and the patient's body form a close and stable state, which provides a stable foundation for the surgical operation; during the operation, when liquid overflows from the patient's wound, the absorbent piece on the limiting towel absorbs the overflowed liquid to ensure that the liquid does not accumulate on the surface of the surgical towel or flow to the vicinity of the surgical area, and the surgical area is always kept dry and clean. During the entire operation, the interface component and the abutment piece continue to maintain a fixed state of the patient's body part, and the limiting towel always fits closely to the patient's body, effectively preventing the patient's body part from moving due to surgical operations, the patient's own stress response and other factors, and ensuring that the operation can be carried out smoothly in a stable environment;

[0006] In the above technology, through the synergistic effect of the limiting towel, the interface component and the abutment part, the patient's body part can be accurately positioned and fixed according to the patient's body contour. After the patient lies on the pad towel, the interface component deforms the limiting towel, and the inner wall of the limiting towel gathers toward the patient's body. The abutment part cooperates with it and abuts against the patient's body. This can not only effectively prevent the patient from affecting the surgical operation due to unconscious movement during the operation, but also provide the patient with support that fits the body curve, greatly improving the patient's comfort during the operation and reducing the risk of movement caused by physical discomfort; the adsorbent in the above technology can timely and effectively absorb the liquid overflowing from the patient's wound during the operation, avoid the accumulation and flow of liquid on the surface of the surgical towel, thereby significantly reducing the risk of contamination of the surgical area, which not only helps to maintain the sterile environment of the surgical area and ensure the smooth progress of the operation, but also reduces postoperative infection. The incidence of complications such as cataract and cerebrospinal fluid is greatly reduced, which has a positive significance for the patient's postoperative recovery. The design of the unilateral connection between the pad and the cover makes the surgical towel more flexible and versatile when facing different types of operations and patient body parts. Medical staff can flexibly adjust the use of the pad and the cover according to the actual surgical situation to better meet the needs of diverse surgical scenarios and reduce the cost and time consumption of frequent replacement of surgical towels of different specifications due to differences in surgical types. In traditional operations, medical staff may need to spend extra time and energy to fix the patient's body parts or deal with wound overflow. The design of the above-mentioned technology integrates the local fixation of the patient's body and the treatment of fluid accumulation into the surgical towel. Medical staff no longer need to use additional complex tools and can focus more on the surgical operation itself, which effectively improves the convenience and fluency of the surgical operation and helps the operation to be performed more efficiently.

[0007] The present invention is further provided that: an inflation chamber is hollowly opened in the limiting towel, the limiting towel is made of rubber material and a polyurethane coating is sprayed on the surface of the limiting towel through a spraying process, the interface component includes an inflation nozzle group used to connect with the air outlet of an external air pump to fill the inflation chamber with gas to inflate the limiting towel, and the inflation direction of the limiting towel is arranged toward the center of the containing groove.

[0008] The advantages of adopting the above technical solution are as follows: the positioning towel in the above technology is provided with a hollow inflatable chamber, which is connected to an external air pump through an interface component, and the amount of gas filled into the inflatable chamber can be accurately controlled according to the shape of the patient's body part and the surgical requirements. When the gas is filled, the positioning towel inflates and expands toward the center of the container, which can closely fit the contour of the patient's body, achieve accurate fixation of the patient's body part, avoid affecting the surgical operation due to the movement of the patient, and greatly improve the stability of the patient's body during the operation; the positioning towel is made of rubber material, which has good wear resistance and tear resistance, can withstand a certain degree of friction and external force during the operation, is not easy to be damaged, and prolongs the service life of the surgical auxiliary towel. At the same time, the surface is sprayed with polyurethane coating through a spraying process, which further enhances the strength and toughness of the limiting towel, making it more durable and reducing the risk of surgery being affected by damage to the limiting towel. The polyurethane coating is smooth and not easy to be stained. After the operation, it is easy to clean and disinfect the limiting towel, which not only helps to maintain the hygiene of the surgical auxiliary towel and reduce the risk of cross infection, but also ensures that it can maintain good performance after multiple uses, so that medical staff can choose disposable auxiliary towels or repeatedly disinfect and recycle auxiliary towels according to actual needs; after the rubber limiting towel is inflated, due to the flexibility of its material, it can evenly distribute the pressure on the contact part of the patient's body. Compared with traditional rigid fixation devices, it will not cause local compression on the patient's body, which not only ensures the fixation effect, but also improves the patient's comfort during the operation; the design of the interface component cooperating with the external air pump in the above technology makes the inflation operation of the limiting towel simple and convenient. Medical staff only need to connect the interface component to the air outlet of the air pump to quickly inflate the limiting towel. There is no need for complicated operation procedures, which saves surgical preparation time and improves work efficiency. By controlling the inflation volume, the limiting towel can adapt to the needs of patients of different body shapes and different surgical sites, improving the versatility of surgical auxiliary towels. Whether it is for patients with larger or smaller bodies, or surgeries on different parts of the body, a good fixation effect can be achieved by adjusting the inflation volume, reducing the trouble of preparing multiple specifications of fixation devices due to individual differences in patients.

[0009] The present invention is further configured as follows: the inflation chamber is composed of a plurality of inflation chambers, the plurality of inflation chambers are evenly distributed on the limiting towel, the inflation nozzle group is composed of a plurality of air nozzles for connecting with the air outlet of an external air pump, the plurality of air nozzles correspond one-to-one to the plurality of inflation chambers and each air nozzle is connected to the corresponding inflation chamber.

[0010] The benefits of adopting the above technical solution are: the inflatable chamber in the above technology is composed of a number of inflatable chambers evenly distributed on the limiting towel, and each inflatable chamber corresponds to an air nozzle, so that medical staff can independently inflate different inflatable chambers through the air nozzles according to the complex shape of the patient's body and the support needs of different parts. For example, for parts with irregular body curves, the inflation volume of the inflatable chamber at a specific position can be increased or decreased to achieve precise fitting of the limiting towel to the patient's body contour, provide a more stable and comfortable fixation effect, and effectively avoid patient discomfort or surgical interference caused by improper fixation; different surgeries may have different emphases on the fixation of the patient's body. The design of independently controllable inflatable chambers can allow medical staff to focus on According to the specific type of surgery, the support strength of each area can be flexibly adjusted. For example, in some delicate surgeries that require specific parts of the patient to remain absolutely still, the air pressure in the corresponding inflatable cavity can be increased to enhance the fixation effect and ensure the smooth progress of the operation. In the above technology, several evenly distributed inflatable cavities work together to evenly disperse the pressure of the patient's body on the limiting towel. Compared with a single inflatable cavity, this design avoids the situation of excessive or insufficient local pressure, so that the patient's body is more evenly stressed during the fixation process, further improving the stability of fixation and reducing the possibility of movement of the patient due to uneven local pressure. At the same time, even if a certain air nozzle or inflatable cavity fails, the other inflatable cavities can continue to maintain the basic fixation function of the limiting towel. For example, if one of the air nozzles is blocked or an inflatable cavity is accidentally damaged, the remaining normal inflatable cavities can still ensure the effective support and fixation of the patient's body by the limiting towel, which improves the reliability of the entire fixation system and reduces the risk of affecting the progress of the operation due to component failure.

[0011] The present invention further provides: the abutment member includes a plurality of abutment strips distributed circumferentially on the inner circumferential wall of the limiting towel, the abutment strip is composed of a connecting portion and a bending portion, the connecting portion is connected to the inner circumferential wall of the limiting towel, the bending portion is connected to the connecting portion, the abutment strip is made of shape memory alloy material, the abutment strip has a first form within a first temperature range, and the abutment strip has a second form within a second temperature range, the bending portion of the abutment strip is bent toward the connecting portion in the first form, and the bending portion of the abutment strip is deformed and bent toward the direction of the receiving groove in the second form.

[0012] The advantages of adopting the above technical solution are as follows: the abutment member is composed of a plurality of abutment strips distributed on the inner peripheral wall of the limiting towel, and the abutment strips are made of shape memory alloy. In the preoperative preparation stage, when it is in the first temperature range, the abutment strip is in the first shape, and the bent portion is bent toward the connecting portion, which is convenient for storage and placement. When the patient lies on the towel, as the temperature of the surgical environment changes or the contact with the patient's body surface is affected by the patient's body temperature and enters the second temperature range, the abutment strip is transformed into the second shape, and the bent portion is bent toward the direction of the receiving groove, which can automatically fit the patient's body contour, provide tight and comfortable abutment fixation, and effectively avoid the patient's The patient's body movement affects the surgical operation. The unique design of the abutment strip enables it to flexibly adjust the contact state according to the different shapes and pressure distribution of various parts of the body when it fits the patient's body. Compared with traditional rigid abutment parts, the abutment strip made of shape memory alloy can effectively reduce the local pressure on the patient's body, significantly improve the patient's comfort during the operation, and reduce the problems such as physical discomfort or poor blood circulation caused by long-term pressure; the adaptive fitting ability of the abutment strip can always firmly fix the patient's body, prevent the patient from interfering with the surgical operation due to changes in body position during the operation, and reduce the risk of surgery. At the same time, its good flexibility and adaptability avoid accidental damage to the patient's body due to too tight or too loose abutment, providing a strong guarantee for surgical safety; the abutment strip automatically changes its shape due to temperature changes or contact with the patient's body surface, and is affected by the patient's body temperature, without the need for medical staff to manually perform complex adjustment operations. In the preparation stage of the operation, you only need to put the surgical towel in place, and as the ambient temperature changes, the abutment strip can automatically adjust to a suitable fixed shape, saving the time for surgical preparation and improving work efficiency; the shape memory alloy material has good stability and durability, and the abutment strip structure is relatively simple and not easy to damage. After use, it only needs to be cleaned and disinfected according to the conventional process to ensure the reliability of its performance, reduce the maintenance cost and difficulty, and facilitate the long-term use and management of surgical towels; the shape memory alloy in the above technology is a prior art, which has a certain form within a certain temperature range, such as the morphological changes affected by the temperature range or the patient's body temperature as described in this article, for example, the first temperature range is 30 degrees lower than the patient's standard body temperature, and the second temperature range is a temperature range higher than 30 degrees. The deformation of the abutment strip is achieved by the change in the temperature range. Because it is a prior art, its structure and deformation principle will not be described in detail.

[0013] The present invention is further provided that: the top wall of the limiting towel is covered with an adsorption towel, the adsorption towel is connected to the limiting towel, the bottom wall of the adsorption towel and the top wall of the limiting towel are gap-matched to form an adsorption cavity, the adsorption component includes a plurality of negative pressure nozzles for connecting with an external vacuum negative pressure pump to generate a negative pressure adsorption force in the adsorption cavity and a plurality of suction nozzles for connecting with the adsorption cavity to discharge the liquid sucked by the adsorption cavity to the outside, the negative pressure nozzle is connected to the adsorption cavity, a plurality of suction ports for sucking the liquid discharged from the patient during surgery are evenly distributed on the inner circumferential wall of the adsorption towel, the suction port is connected to the adsorption cavity, and the opening of the suction port is flush with the inner circumferential wall of the limiting towel.

[0014] The advantages of adopting the above technical solution are as follows: in the above technology, by setting a negative pressure nozzle connected to an external vacuum negative pressure pump, the adsorption chamber can generate a strong negative pressure adsorption force, which can quickly and effectively adsorb the fluid discharged from the patient during the operation, ensuring that the operating area always remains dry, greatly reducing the problems of blurred surgical field of view and increased risk of infection caused by fluid accumulation, providing a good environment for the smooth progress of the operation, timely and effectively adsorbing the fluid discharged from the patient during the operation, avoiding the long-term stay of the fluid in the operating area to breed bacteria, significantly reducing the risk of surgical wound infection, and helping to improve the success rate of the operation and the patient's Postoperative recovery effect; at the same time, the suction ports evenly distributed on the inner wall of the absorption towel can absorb the fluid discharged from the patient during the operation from all directions. No matter which direction the liquid overflows from the wound, it can be captured by the suction port in time and discharged through the absorption cavity, which greatly improves the comprehensiveness and efficiency of liquid adsorption. Compared with the traditional single suction port design, it can clean the liquid in the surgical area more quickly; the gap between the bottom wall of the absorption towel and the top wall of the limiting towel cooperates to form an adsorption cavity. This structure not only ensures the sealing of the adsorption cavity, so that the negative pressure adsorption force can be effectively exerted, but also facilitates the installation and disassembly of the absorption towel, and is convenient for cleaning or replacing the absorption towel after surgery. At the same time, the clearance fit design can also prevent the liquid from flowing back to the contact area between the limiting towel and the patient's body during the adsorption process, further ensuring the comfort and safety of the patient; the opening of the suction port is flush with the inner wall of the limiting towel, which can make the suction port closer to the patient's wound on the one hand, thereby improving the efficiency of liquid suction; on the other hand, the flush design avoids the discomfort that may be caused to the patient's body due to the protrusion of the suction port, and also reduces the risk of damage caused by collision between surgical instruments and the suction port, thereby optimizing the practicality and safety of the overall structure; in the above-mentioned technology, the adsorption towel and the limiting towel are connected and arranged, and the structure is relatively independent. After the operation, if the adsorption towel is contaminated or damaged, it can be easily replaced separately without replacing the entire limiting towel, thereby reducing the cost of use and the difficulty of maintenance. The adsorption towel and the limiting towel can be detachably connected by magnetic attraction or Velcro connection according to the actual use method or installation method, thereby improving the practicality and scope of use. At the same time, the detachable connection method is a prior art, so it will not be described in detail.

[0015] The present invention further provides that: a one-way valve is provided in the suction nozzle.

[0016] The advantages of adopting the above technical solution are as follows: the one-way valve in the above technology is like a solid "valve", which only allows liquid to be discharged from the adsorption chamber to the outside through the suction nozzle, and prevents external liquid or air from flowing back into the adsorption chamber. This avoids the risk of the discharged liquid returning to the adsorption chamber again and contaminating the surgical area, always keeping the surgical area clean, and providing reliable guarantee for the smooth progress of the operation; when the adsorption chamber generates negative pressure adsorption force under the action of the negative pressure nozzle, the one-way valve ensures the sealing of the adsorption chamber, prevents external air from entering through the suction nozzle, maintains the stability of the negative pressure in the adsorption chamber, and enables the adsorption component to continuously and efficiently adsorb the liquid discharged by the patient during the operation, ensuring the reliability of the adsorption effect and avoiding the reduction of adsorption efficiency due to unstable negative pressure.

[0017] The present invention further provides that: a plurality of suction nozzle positions are arranged in one-to-one correspondence with a plurality of negative pressure nozzle positions and the suction nozzle position is arranged lower than the negative pressure nozzle position.

[0018] The above technical solution is beneficial in that the suction nozzle and the negative pressure nozzle are set in a one-to-one correspondence, so that the negative pressure generated by the negative pressure nozzle can act more specifically on the area near the suction nozzle. This means that when the adsorption chamber generates negative pressure, each suction nozzle can more efficiently suck the surrounding liquid into the adsorption chamber under the action of the corresponding negative pressure, and discharge it through the suction nozzle. This precise correspondence avoids the dead corner of liquid suction caused by uneven negative pressure distribution, and significantly improves the efficiency of liquid drainage; at the same time, the position of the suction nozzle is lower than the position of the negative pressure nozzle, which utilizes the characteristic that the liquid naturally flows downward under the action of gravity. On the basis of negative pressure adsorption, gravity assists the liquid to flow to the suction nozzle faster, making the liquid easier to collect and discharge. This design optimizes the liquid flow path inside the adsorption chamber, enhances the overall adsorption effect, ensures that the liquid in the surgical area can be quickly and thoroughly cleaned, maintains a clear surgical field of view and a dry operating area; and because the suction nozzle is at a lower position, in the process of adsorbing the liquid, the liquid is preferentially contacted rather than the gas. This helps to reduce the problem of negative pressure instability caused by the suction nozzle inhaling too much air. When the negative pressure nozzle generates negative pressure, air usually enters from a higher position, while the suction nozzle at a lower position can more effectively suck away the liquid first, thereby maintaining a stable negative pressure environment in the adsorption chamber and ensuring that the adsorbent works continuously and stably. This position setting improves the reliability of the entire adsorbent system by optimizing liquid drainage and preventing gas interference. During surgery, stable liquid adsorption and discharge functions are essential for the smooth progress of the operation. A reliable adsorbent system can reduce the risk of surgical interruption due to equipment failure, provide medical staff with a stable surgical auxiliary environment, and enhance the controllability of the surgical process.

[0019] The present invention further provides that: a plurality of elastic bands are arranged on the cover towel, the plurality of elastic bands are evenly distributed along the length direction of the pad towel, and the elastic bands are arranged to wrap around the pad towel and the cover towel.

[0020] The above technical solution is beneficial in that: the elastic bands evenly distributed along the length of the pad on the cover are wrapped around the pad and cover. During the operation, the patient's movement, the vibration of the operation and other factors may cause the surgical auxiliary towel to shift. The elasticity and winding setting of the elastic band can tightly bind the pad and cover, so that they can maintain a relatively fixed position on the bed and the patient's body, avoiding the impact of the surgical field and operation due to the displacement of the auxiliary towel, ensuring the smooth progress of the operation, and its combination with the limiting towel further improves the limiting ability of the patient's limbs.

[0021] The present invention further provides that: the cover towel is made of a temperature-sensitive phase-change material.

[0022] The above technical solution is beneficial in that: the cover is made of temperature-sensitive phase change material, which can sensitively sense the patient's body temperature changes. When the patient's body temperature tends to be too high or too low, the material will undergo corresponding physical changes due to temperature changes, such as color changes or morphological adjustments. Abnormal body temperature of patients during surgery may cause a variety of complications, such as low body temperature may cause coagulation disorders, cardiovascular complications, etc., and high body temperature may affect neurological function, etc. The temperature-sensitive phase change material cover can promptly remind medical staff, effectively reduce various risks caused by abnormal body temperature, and ensure the safety of patients during surgery.

[0023] The present invention further provides that: a plurality of magnetic suction sheets for magnetically cooperating with an external operating table are embedded on the bottom wall of the pad.

[0024] The advantages of adopting the above technical solution are that: the several magnetic sheets embedded in the bottom wall of the mat can form a magnetic fit with the external operating table, generating a strong attraction, so that the mat can be firmly attached to the operating table. During the operation, whether it is the adjustment of the patient's position or the vibration caused by various operations performed by medical staff, the mat can remain stable and will not easily shift or slide, providing a reliable basis for the smooth progress of the operation; traditional surgical auxiliary towels may only rely on friction to be placed on the operating table. In some special cases, such as the tilting operation of the operating table or the large-scale movement of the patient, there is a risk of slipping. The setting of the magnetic sheet effectively avoids this situation, ensuring that the mat is always in the correct position, ensuring the coverage integrity of the surgical area, and reducing the risk of contamination caused by the mat slipping during the operation; at the same time, the design of the magnetic sheet is highly versatile, whether the operating table is made of metal or contains magnetically absorbable parts, the mat can effectively cooperate with it. This allows the surgical auxiliary towel to be used on different types of operating beds in different hospitals without the need for special design or modification for specific operating beds, which improves the scope of application and practicality of the product.
