Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary instruments, and in particular to a novel hemostatic device for general surgery. Background Art

[0002] General surgery is a clinical discipline that uses surgery as the main method to treat liver, bile duct, pancreas, gastrointestinal, anorectal, vascular diseases, thyroid and breast tumors and other diseases such as trauma. It is the largest specialty in the surgical system. After the existing general surgery, the patient's wound needs to be hemostatic, so a hemostatic device is needed; The existing technology has the following defects: 1. The currently used hemostatic method cannot ensure that the patient's wound has good ventilation, which will cause the patient's wound to be in a sealed environment and easily breed anaerobic bacteria, which is very unfavorable for the rapid hemostasis and healing of the patient's wound; 2. The structure of the hemostatic device is fixed. During the surgical hemostasis process, it is impossible to achieve hemostasis operations at different positions on the patient's limbs and waist, which is very inconvenient to use and occupies the limited space on the operating table; In order to overcome the first defect, the prior art (application number: 202210887149.0, Chinese patent with application date of 2022-07-26) discloses a novel hemostatic device for general surgery, which purifies air dust by filtering activated carbon inside the suction nozzle, absorbs air moisture by the drying plate, and sterilizes the air with a sterilizing lamp and blows it into the inner side of the hemostatic gauze layer through the circular holes on the surface of the airflow plate, thereby ensuring that the patient's wound is in a ventilated environment, preventing the patient's wound from sealing and breeding anaerobic bacteria, and improving the hemostatic and healing effect of the wound of general surgery patients. The first defect mentioned above is solved by this structure; In order to overcome the second defect, the prior art (application number: 202210579830.9, Chinese patent with application date of 2022-05-25) discloses a novel hemostatic device for general surgery. By setting the hemostatic device on one side edge of the operating table, the space occupied by the operating table is reduced. After installation and fixation, the patient's limbs and waist are clamped and hemostatically controlled by a fixed airbag splint and a movable airbag splint with airbags. The operation is simple and fast, and the height and angle of the fixed airbag splint and the movable airbag splint are adjustable to facilitate the operation of medical staff. The second defect mentioned above is solved by this structure; Although the prior art 1 and the prior art 2 can overcome the above defects, the hemostatic tightening parts of the above structures are simple plane or arc surface structures, which makes it difficult to closely fit with the skin of wounds at different locations when stopping bleeding, resulting in poor hemostatic effect; and the hemostatic tightening parts of the above devices are all fixedly set and difficult to disassemble and clean, resulting in insufficient cleanliness of the hemostatic devices and causing infection problems; In view of the above problems, it is urgent to carry out innovative design based on the original equipment. Therefore, we have proposed a new type of hemostatic device for general surgery that can solve the above problems well. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of hemostatic device for general surgery to solve the problem raised in the above background technology that the hemostatic and tightening parts of the devices currently on the market are simple plane or arc surface structures, which makes it difficult to achieve close fitting contact with the skin of wounds in different positions when stopping bleeding, thereby resulting in poor hemostatic effect; and the hemostatic and tightening parts of the above devices are fixed and difficult to disassemble and clean, resulting in the problem of insufficient cleanliness of the hemostatic device and causing infection.

[0004] To achieve the above object, the present invention provides the following technical solution: A novel hemostatic device for general surgery, comprising: a support frame, an outer wrapping layer is arranged on the inner side of the support frame, and an air bag is arranged on the inner bottom of the outer wrapping layer; The interior and top of the outer wrapping layer are provided with a deformation assembly, and the deformation assembly includes seven linkage pressure plates arranged horizontally and located at the top of the airbag inside the outer wrapping layer, and two adjacent linkage pressure plates are rotatably connected by connecting pins, and the tops of the three linkage pressure plates located at the center and both sides are fixedly connected with a fixing seat, and the inner side of the fixing seat is rotatably connected with a connecting rotating block, and the top of the connecting rotating block is fixedly connected with a magnetic rod, and the magnetic rod slides upward to penetrate the top outer side of the support frame, and a first spring is fixedly connected between the magnetic rod and the top of the support frame, and an electromagnet is embedded and installed at a position where the support frame is sleeved on the outside of the three first springs; When in use, the support frame is first placed on the outside of the patient's wound, and the airbag is fitted to the wound. The top thrust of the first spring will provide a downward squeezing force for the magnetic rod, and the magnetic rod continues to drive the three linked pressure plates to squeeze downward through the connection of the rotating block and the fixed seat. Since the multiple linked pressure plates are rotatably connected, the linked pressure plate as a whole can be rotated and adjusted accordingly according to the surface curvature of different parts of the patient to form a curvature that fits therewith. The airbag at the bottom of the linked pressure plate is synchronously adjusted to the curvature, thereby ensuring a close fit to the bleeding wound. At this time, the three magnetic rods are manually squeezed downward to provide further hemostatic pressure, and the three electromagnets are energized through the control system. The electromagnets generate magnetic force to attract the magnetic rods to fix the position of the magnetic rods to maintain a constant pressure and prevent loosening, thereby effectively ensuring the hemostatic effect. The bottom of the airbag is detachably provided with a waterproof cloth through an installation component, and a sterile cotton cloth is fixedly bonded to the bottom of the waterproof cloth. The sterile cotton cloth is fitted against the patient's bleeding wound to stop bleeding, thereby ensuring the cleaning effect, and the waterproof cloth can prevent the blood from continuing to penetrate upward into the airbag and causing difficulty in cleaning. At the same time, the waterproof cloth and sterile cotton cloth can be easily replaced after use through the installation component, thereby ensuring the cleanliness of the device.

[0005] Preferably, the two sides of the linkage pressure plate are respectively formed into a convex edge and a concave groove that are engaged with each other, so as to facilitate the rotational connection between the two through a connecting pin.

[0006] Preferably, the two electromagnets located on both sides are formed into a straight slot structure, and a movable cavity is reserved inside for the magnetic rod to move left and right, so that when the linkage pressure plate at the bottom is rotated and adjusted, the lateral movement change of the magnetic rod can be adapted.

[0007] Preferably, preliminary fixing components are provided on both sides of the bottom of the support frame, and the preliminary fixing components include movable rods slidably connected to both sides of the bottom of the support frame, a second spring is fixedly connected between the movable rods and the outer wall of the support frame, the movable rod is fixedly connected to a connecting seat on the side wall inside the support frame, the inner side of the connecting seat is rotatably connected to an extrusion arc plate, and a plurality of suction cups are fixedly installed on the side walls of the extrusion arc plate.

[0008] By adopting the above technical solution, when the support frame is placed on the outside of the patient's wound, when the second spring drives the movable rod to push inward, the two extrusion arc plates will be initially clamped on both sides of this part of the patient, and the connecting seat is rotatably connected to the extrusion arc plate, so that the extrusion arc plate can adjust the inclination angle according to the surface curvature of this part, so that it fits the skin better, and is adsorbed on the skin surface by multiple suction cups, which can improve the stability of the extrusion arc plate clamping, thereby ensuring the stability of the initial fixation of the device.

[0009] Preferably, a rotating shaft is formed at both ends of the extruded arc plate, the rotating shaft is rotatably connected to the inner sides of the two ends of the connecting seat, and a torsion spring is fixedly connected between the rotating shaft and the outer end wall of the connecting seat. Through the arrangement of the torsion spring and the rotating shaft, when the device is removed after use, the two extruded arc plates can be rotated and restored to a horizontal state to facilitate the next use.

[0010] Preferably, an inflation component is provided on both sides of the airbag, and the inflation component includes a fixed bent pipe fixedly connected to both sides of the support frame, a negative pressure ball is fixedly sleeved on the top of the fixed bent pipe, a multi-head connecting pipe is fixedly installed inside the extrusion arc plate, and the branch pipe openings of the multi-head connecting pipe pass through the inner side of each suction cup, the multi-head connecting pipe is connected to the fixed bent pipe through a first fixedly plugged hose, and the two sides of the airbag are connected to the fixed bent pipe through a second hose.

[0011] By adopting the above technical solution, when the extrusion arc plate is clamped on both sides of the patient's injured part, the negative pressure ball is squeezed and deflated. When the suction cup is adsorbed on the patient's skin surface, the negative pressure ball is released. The negative pressure ball expands outward and resets due to its elastic material. It then absorbs the residual air inside the suction cup through the fixed elbow, the first hose, and the multi-head connecting tube in turn, making the inside of the suction cup a vacuum state, thereby greatly improving the adsorption strength of the suction cup. Then, the first hose is pinched and the negative pressure ball is squeezed deflated in turn. The internal air of the negative pressure ball will enter the interior of the airbag through the fixed elbow and the second hose in turn, causing the airbag to expand to provide additional hemostatic pressure.

[0012] Preferably, a spoiler is provided inside the fixed bend pipe, and the spoiler is fixedly connected to a handwheel outside the fixed bend pipe through a rod body. After the airbag is inflated, the handwheel is turned so that the spoiler blocks the fixed bend pipe to prevent the air in the airbag from flowing back into the negative pressure ball.

[0013] Preferably, the installation assembly includes snap-on hooks fixedly connected to the outer walls of both ends of the linkage pressure plates on both sides, the four corner edges of the waterproof cloth are formed with connecting ears, the ends of the connecting ears are fixedly connected with clamping blocks, and the four clamping blocks are respectively snap-on hooked on the inner sides of the corresponding connecting ears.

[0014] By adopting the above technical solution, the waterproof cloth can be quickly installed on the bottom of the airbag by using the corresponding snap-fit ​​of four sets of snap-fit ​​hooks and snap-fit ​​blocks, and when disassembling, it is only necessary to force the snap-fit ​​block out from the top opening of the snap-fit ​​hook.

[0015] Preferably, the clamping hook is an annular structure with a central angle exceeding 180°, and the clamping block is composed of a cylindrical clamping portion and a wider limiting portion. The clamping hook clamps the clamping portion of the clamping block to limit the clamping effect, which can ensure the stability of the clamping while facilitating the removal of the clamping block from the top opening of the clamping hook. In addition, the setting of the wider limiting portion of the clamping block can prevent the clamping block from escaping from the clamping hook from both ends.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the novel hemostatic device for general surgery is provided with a deformation component, and utilizes the pushing of the first spring and the rotation connection between the multiple linkage pressure plates, so that the linkage pressure plates as a whole can be rotated and adjusted to fit the surface curvature of different parts of the patient, and the electromagnet and the magnetic rod can cooperate to maintain a constant pressure force, thereby ensuring the hemostatic effect; the waterproof cloth and the disinfection cotton cloth can be detachably installed under the airbag through the installation component, which can prevent the situation that blood seepage causes difficulty in cleaning, and the waterproof cloth and the disinfection cotton cloth are easy to replace; 1. By setting a deformation component, when in use, the support frame is first placed on the outside of the patient's wound, and the airbag is fitted to the wound. The first spring drives the three magnetic rods, the connecting rotating block, the fixing seat, and the linkage pressing plate to squeeze downward in sequence through the top thrust. Since the multiple linkage pressing plates are rotatably connected, the linkage pressing plate as a whole can be rotated and adjusted accordingly according to the surface curvature of different parts of the patient to form a curvature that fits therewith. The airbag adjusts the curvature synchronously to closely fit and cover the bleeding wound surface, and the position of the magnetic rod is fixed by the cooperation of the three electromagnets and the magnetic rod to maintain a constant pressure force and prevent loosening, thereby effectively ensuring the hemostatic effect; 2. The waterproof cloth and the disinfection cotton cloth can be detachably installed under the airbag through the installation component. The disinfection cotton cloth is used to fit the bleeding wound of the patient to stop bleeding, which can ensure the cleaning effect. The waterproof cloth can prevent the blood from continuing to penetrate upward into the airbag and causing difficulty in cleaning. At the same time, the waterproof cloth and the disinfection cotton cloth can be easily replaced after use through the installation component, thereby ensuring the cleanliness of the device; 3. By setting up a preliminary fixing component, when the support frame is placed on the outside of the patient's wound surface, when the second spring drives the movable rod to push inward, the two extrusion arc plates will be initially clamped on both sides of this part of the patient. Through the rotational connection between the connecting seat and the extrusion arc plate, the extrusion arc plate can adjust the inclination angle according to the surface curvature of this part, so that it fits the skin better, and through multiple suction cups adsorbed on the skin surface, the stability of the extrusion arc plate clamping can be improved, thereby ensuring the stability of the initial fixation of the device; 4. By setting up an inflation component, when the extrusion arc plate is clamped on both sides of the patient's injured part, the negative pressure ball is squeezed and deflated. When the suction cup is adsorbed on the patient's skin surface, the negative pressure ball is released. The negative pressure ball expands outward and resets due to its elastic material, and absorbs the residual air inside the suction cup through the fixed elbow, the first hose, and the multi-head connecting tube in turn, so that the inside of the suction cup is in a vacuum state, thereby greatly improving the adsorption strength of the suction cup, and then the first hose is pinched and the negative pressure ball is squeezed in turn, and the internal air of the negative pressure ball will enter the interior of the airbag through the fixed elbow and the second hose in turn, so that the airbag expands to add hemostatic pressure.
