Description

Technical Field

[0001] The invention relates to the technical field of hemostat, and in particular to a multifunctional hemostat for clinical hepatobiliary and pancreatic surgery. Background Art

[0002] Hepatobiliary and pancreatic surgery often involves the treatment of complex blood vessels and important organs, and is highly complex and risky. Once bleeding occurs, it will not only increase the difficulty of the operation, but may also endanger the patient's life. Therefore, this type of surgery has extremely high requirements for bleeding control during the operation; traditional hemostasis methods, such as gauze compression, suture hemostasis, etc., may not be able to meet the needs of hepatobiliary and pancreatic surgery in some cases, especially for some bleeding points that are difficult to reach or have limited vision, traditional methods are often difficult to work; although modern technologies such as electrocoagulation hemostasis have improved the efficiency of hemostasis to a certain extent, there are still problems such as complex operation and limited field of view. At the same time, electrocoagulation hemostasis will produce fumes containing harmful substances such as carbon monoxide, acrylonitrile, benzene, etc., which will pose a threat to the safety of patients and the external environment.

[0003] Existing clinical hemostat devices for hepatobiliary and pancreatic surgery, such as a multifunctional clinical hemostat for hepatobiliary and pancreatic surgery provided by publication number CN114431952B, include a collecting plate, a threaded rod is movably installed on the upper surface of the collecting plate, a first driving rod is fixedly installed on the bottom of the collecting plate, a driving block is fixedly installed on the other end of the first driving rod, a driving sleeve is movably sleeved on the outer surface of the first driving rod, and slide grooves are provided on the front and rear sides of the inner cavity of the driving sleeve; the multi-kinetic hemostat for hepatobiliary and pancreatic surgery can absorb the harmful gas generated by the electrocoagulation hemostat by starting the exhaust fan, and at the same time start the disinfector, and use the nozzle to introduce the disinfectant into the inner cavity of the gas collecting pipe to disinfect the harmful gas, which can be convenient for the user to directly The exhaust gas will not cause air pollution, and the electrocoagulation hemostat in the inner cavity of the protective sleeve can be disinfected to ensure the hygiene of the electrocoagulation hemostat blade; but since the application needs to push the push plate and the clamping block and other structures while manually rotating the threaded rod, it still needs to be fixed with the help of an external fixing device to perform electrocoagulation hemostasis. Since the application is too cumbersome, it is easy to cause the electrocoagulation hemostasis operation to be untimely, which affects the safety of the patient; at the same time, the application uses an exhaust fan and a disinfection instrument on one side of the electrocoagulation hemostat to absorb the waste gas and disinfect the hemostat, which is easy to reduce the waste gas treatment efficiency. At the same time, disinfection only by a disinfection instrument cannot remove pollutants such as coagulated blood remaining on the electrocoagulation hemostat blade, which leads to incomplete disinfection. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention aims to provide a multifunctional clinical hemostat for hepatobiliary and pancreatic surgery.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] The inventors have found that in hepatobiliary and pancreatic surgery, when bleeding occurs in blood vessels or organs, traditional hemostasis methods, such as gauze compression and suture hemostasis, may not be able to meet the needs of hepatobiliary and pancreatic surgery in some cases, especially for some bleeding points that are difficult to reach or have limited vision. Traditional methods are often difficult to work; although modern technologies such as electrocoagulation hemostasis have improved the efficiency of hemostasis to a certain extent, there are still problems such as complex operation and limited field of view. At the same time, other existing equipment also has the problem of low efficiency in treating the waste gas generated by electrocoagulation hemostasis, and incomplete cleaning of the electrocoagulation hemostasis head.

[0023] Based on the above findings, the present application proposes a multifunctional clinical hemostat for hepatobiliary and pancreatic surgery, which designs an exhaust gas treatment component and connects the air inlet at the bottom through a smoke exhaust fan to absorb the harmful gas generated by the electrocoagulation hemostat during hemostasis, and after filtering through the activated carbon filter layer, it is discharged through the exhaust hole opened on the lower fixed seat; a disinfection component is designed to spray the disinfectant in the reservoir onto the surface of the electrocoagulation hemostat through a disinfection nozzle for disinfection, and through the pull-down and rebound action, the brush fixed on the inside of the reservoir cleans the surface of the electrocoagulation hemostat. It has the advantages of easy use, high exhaust gas treatment efficiency, good cleaning effect and simple structure.

[0024] See also Figure 1-Figure 4 The present application discloses a multifunctional clinical hemostat for hepatobiliary and pancreatic surgery, comprising a lower fixing seat 1 and an upper fixing seat 2 connected by threads. The overall shape of the lower fixing seat 1 and the upper fixing seat 2 are both approximately cylindrical, and the material can be a lightweight metal material or a plastic material with good strength. The bottom of the lower fixing seat 1 is fixed with an electrocoagulation hemostat head 3 for hemostasis during clinical hepatobiliary and pancreatic surgery. The electrocoagulation hemostat head 3 can refer to the more common electrocoagulation hemostat products on the market, such as the electrocoagulation hemostat products produced by Aier Medical Equipment Factory, which can be turned on or off by a switch. When fixing, it can be fixed to the bottom center of the lower fixing seat 1 in a direction perpendicular to the bottom surface of the lower fixing seat 1 by threaded connection or welding.

[0025] See also Figure 5 as well as Figure 6 The lower fixed seat 1 is provided with an exhaust gas treatment component 4 for treating harmful gases generated during electrocoagulation hemostasis. The exhaust gas treatment component 4 includes a main chamber 401 opened in the middle of the lower fixed seat 1. The main chamber 401 is cylindrical in shape. A slider 402 is slidably arranged in the main chamber 401. Fig. 9 as well as Fig.10 In some embodiments, the slider 402 is a cylindrical structure with a hollowed-out middle portion, a circular connecting plate is fixed in the middle of the cylindrical structure, and a plurality of air holes are evenly distributed on the connecting plate for passing air; A smoke fan 403 is provided at the middle part below the connecting plate, i.e., at the bottom center of the slider 402. The motor of the smoke fan 403 is fixed below the connecting plate. When the blades of the smoke fan 403 rotate, the air in the total chamber 401 can be drawn upward through the air holes evenly distributed on the connecting plate in the middle of the slider 402. The slider 402 is provided with an activated carbon filter layer 404 facing the blades of the smoking fan 403 near the center. Specifically, an activated carbon filter layer 404 with a ring-shaped cross section is fixed above the connecting plate of the slider 402, which can filter the air drawn upward by the smoking fan 403. An elastic pressing sheet 405 that can just cover the upper surface of the activated carbon filter layer 404 is elastically fixed to the top of the slider 402 through a pressing sheet return spring 406. Specifically, a hollowed-out cylindrical thin wall is fixed at the center above the connecting plate of the slider 402 and at the center of the annular structure of the activated carbon filter layer 404. A pressing sheet return spring 406 with one end connected to the center above the connecting plate of the slider 402 is fixed by bolts or the like inside the cylindrical thin wall. The other end of the pressing sheet return spring 406 extends from the top of the cylindrical thin wall and is fixedly connected to the bottom of the elastic pressing sheet 405. The elastic pressing sheet 405 is a thin film structure with a concave middle portion. The material thereof can be a metal or rubber material with good elasticity and flexibility. The cross-sectional diameter thereof should be sufficient to completely cover the top of the activated carbon filter layer 404 when flattened. A slider return spring 407 is fixed at the bottom of the slider 402 near the edge, and the end of the slider return spring 407 away from the slider 402 is connected to the bottom of the main chamber 401. When the smoking fan 403 draws the gas in the main chamber 401 upward, due to the close fit between the upper fixed seat 2 and the lower fixed seat 1, the gas enters the chamber formed between the upper fixed seat 2 and the lower fixed seat 1 after being filtered by the activated carbon filter layer 404.

[0026] See also Figure 7 as well as Figure 8 The bottom of the lower fixed seat 1 is provided with a plurality of air inlet pipes 101, and the plurality of air inlet pipes 101 are connected with the bottom of the main chamber 401. At the same time, the air inlet of the air inlet pipe 101 located at the bottom of the lower fixed seat 1 is also provided with a filter 105 for preliminary filtering of harmful gases; the lower fixed seat 1 is provided with a plurality of exhaust holes 102 near the top, and the plurality of exhaust holes 102 are connected with the top of the main chamber 401. When the smoking fan 403 rotates, the harmful gases generated by the electrocoagulation hemostasis head 3 during hemostasis can be absorbed through the air inlet pipe 101, and preliminarily filtered through the filter 105, and then transmitted to the main chamber 401. The gas continues to move upward through the pores on the connecting plate of the slider 402, and then further filtered through the activated carbon filter layer 404; It should be noted that the slider 402 will block the exhaust hole 102 on the top of the lower fixing seat 1 under normal conditions due to the action of the slider return spring 407, so that the chamber formed between the upper fixing seat 2 and the lower fixing seat 1 is completely filled with filtered gas.

[0027] See also Fig.13 An electric push rod 201 is provided in the middle of the upper fixed seat 2. A motor of the electric push rod 201 is fixed at the center of the upper fixed seat 2 near the top. The electric push rod 201 is a common electric push rod product on the market, which can perform periodic extension and contraction movements at certain time intervals. A piston 202 is fixed at the bottom of the electric push rod 201. The piston 202 can slide up and down along the piston cavity 203 at the bottom of the upper fixed seat 2. Specifically, an upper fixed seat thread 204 and a piston cavity 203 are provided at the bottom of the upper fixed seat 2 from bottom to top. The piston cavity 203 and the piston 202 are tightly matched, and the cross-sectional diameter of the piston cavity 203 is the same as the cross-sectional diameter of the total chamber 401. At the same time, a lower fixing seat thread 104 is provided on the top of the lower fixing seat 1, which is matched with the upper fixing seat thread 204. When the upper fixing seat 2 and the lower fixing seat 1 are fixed by thread matching, the bottom of the piston cavity 203 can be closely connected with the top of the total chamber 401 to form a closed chamber. When the chamber is filled with filtered gas, the electric push rod 201 is extended and the piston 202 is pushed downward. The piston 202 can press the air in the total chamber 401 downward, so that the elastic pressing sheet 405 is quickly deformed and quickly covers the active gas. The upper surface of the carbon filter layer 404 is moved to stop the gas from filling the main chamber 401 (or the closed chamber formed by the piston chamber 203 and the main chamber 401). At this time, since the inside of the closed chamber is completely sealed, the electric push rod 201 continues to move downward, and the slider 402 can be pushed downward by the air pressure to squeeze the slider return spring 407, so that the side wall of the slider 402 no longer blocks the exhaust hole 102, that is, the exhaust hole 102 is connected to the main chamber 401, and the filtered gas can be discharged to the external environment through the exhaust hole 102; When the gas is discharged, due to the decrease in the air pressure in the main chamber 401, the slider 402 begins to reset upward under the action of the slider reset spring 407. At the same time, the electric push rod 201 begins to shorten and drives the piston 202 to reset upward, providing a reset space for the slider 402. When the slider 402 resets upward to block the exhaust hole 102 again, the air pressure in the main chamber 401 increases due to the upward reset action of the piston 202. At this time, the elastic pressing piece 405 quickly restores its initial state due to its own elasticity, the upward push action of the pressing piece reset spring 406, and the effect of increased air pressure, that is, it no longer blocks the upper surface of the activated carbon filter layer 404. At this time, the exhaust gas treatment component 4 is reset as a whole, and gas is re-drawn into the main chamber 401 through the smoking fan 403 to cyclically filter and treat the exhaust gas generated by electrocoagulation hemostasis during hepatobiliary and pancreatic surgery, so that the exhaust gas treatment efficiency of the present invention is improved, which is beneficial to protecting the environment and protecting the safety of patients.

[0028] See also Fig.11 as well as Fig.12 The cleaning assembly 5 includes a liquid reservoir 501 slidably connected to the bottom of the lower fixing seat 1. The liquid reservoir 501 is a relatively flat cylindrical structure with a circular cross-section. In some embodiments, the upper top surface and the lower top surface of the liquid reservoir 501 should be made of metal or plastic with high hardness and strength. At the same time, the side surface of the liquid reservoir 501 located on the outermost side can be made of a material with a certain elasticity; At the bottom of the liquid reservoir 501, there are provided a plurality of disinfection nozzles 502 facing the electrocoagulation hemostasis head 3. When the electrocoagulation hemostasis head 3 stops being used, that is, the entire device is not in electrocoagulation hemostasis operation, the outermost side of the liquid reservoir 501 is pressed inward, so that the disinfectant stored in the liquid reservoir 501 is sprayed onto the surface of the electrocoagulation hemostasis head 3 through the disinfection nozzles 502. In some embodiments, the number of disinfection nozzles 502 can be appropriately increased to make the spraying of the disinfectant more comprehensive. At the same time, a liquid reservoir sealing cover 5011 is installed at the bottom of the liquid reservoir 501 by a threaded connection. By removing the liquid reservoir sealing cover 5011, disinfectant can be added to the inside of the liquid reservoir 501.

[0029] The inner end surface of the liquid reservoir 501 is provided with a brush 503 for cleaning the surface of the electrocoagulation hemostasis head 3. At the same time, the liquid reservoir 501 is slidably connected to the bottom of the lower fixed seat 1. Specifically, a slide bar 504 is fixed on the top of the liquid reservoir 501. The slide bar 504 is slidably installed in a slide groove 103 opened to the bottom of the lower fixed seat 1. A slide bar reset spring 505 is fixed on the upper top surface of the slide groove 103. The end of the slide bar reset spring 505 away from the upper top surface of the slide groove 103 passes through and is fixed to the inside of the slide bar 504. When electrocoagulation hemostasis head 3 is residual on the surface of the electrocoagulation hemostasis head 3, When contaminants such as coagulated blood are stuck on the electrocoagulation hemostasis head 3, first spray disinfectant on the electrocoagulation hemostasis head 3, then pull the liquid reservoir 501 downward as a whole, and clean the surface of the electrocoagulation hemostasis head 3 with the brush 503. When the liquid reservoir 501 is released, the slide bar 504 is reset upward under the action of the slide bar reset spring 505, and drives the liquid reservoir 501 to reset upward as a whole, so that the brush 503 can clean the electrocoagulation hemostasis head 3 again through the reset action. By repeatedly spraying disinfectant and pulling down the liquid reservoir 501, the surface of the electrocoagulation hemostasis head 3 is cleaned multiple times, thereby improving the cleaning effect.

[0030] A handle 6 is also fixed on the lower fixing base 1. Fig.14 Specifically, a fixing ring 602 is provided at the end of the handle 6 away from manual grip, which is located on the outer surface of the lower fixing seat 1, and a fixing groove 406 is provided below the exhaust hole 102. The fixing ring 602 is installed in the fixing groove 406 so that medical staff can hold the device as a whole; the handle 6 is provided with a control switch 601 for controlling the start and stop of the electrocoagulation hemostasis head 3, the smoke exhaust fan 403 or the electric push rod 201 respectively. In some embodiments, one or more control switches 601 can be selected to synchronously turn on or off the electrocoagulation hemostasis head 3, the smoke exhaust fan 403 and the electric push rod 201, or to control the start or stop of the electrocoagulation hemostasis head 3, the smoke exhaust fan 403 or the electric push rod 201 respectively.

[0031] Based on the above-mentioned method for using the multifunctional hemostat for clinical hepatobiliary and pancreatic surgery, the method comprises the following steps: S1. During hepatobiliary and pancreatic surgery, when bleeding occurs in the patient's blood vessels or organs, the hemostat is held as a whole using the handle 6, and the control switch 601 on the handle 6 is used to start the electrocoagulation hemostasis head 3, the smoke exhaust fan 403 and the electric push rod 201; S2, electrocoagulation hemostasis is performed on the bleeding part of the patient through the electrocoagulation hemostasis head 3, and the harmful gas generated during the electrocoagulation hemostasis is sucked into the main chamber 401 through the smoke exhaust fan 403 and the air inlet pipe 101 at the bottom of the lower fixed seat 1, and then filtered through the filter screen 105 and the activated carbon filter layer 404 and sucked into the position of the main chamber 401 located at the upper part of the slider, that is, the closed chamber formed between the piston chamber 203 of the upper fixed seat 2 and the top of the main chamber 401; S3, the electric push rod 201 extends downward and pushes the piston 202 to move downward, so that the elastic pressing sheet 405 located on the top of the slider 402 is quickly deformed downward and squeezes the pressing sheet return spring 406, and at the same time covers the upper surface of the activated carbon filter layer 404, so that the area above the slider 402 in the total chamber 401 is filled with filtered gas and remains sealed. When the electric push rod 201 continues to push the piston 202 downward, the slider 402 moves downward synchronously due to the air pressure and squeezes the slider return spring 407. When the position above the slider 402 in the total chamber 401 is connected to the exhaust hole 102, the filtered gas is discharged to the external environment through the exhaust hole 102; S4. When the electric push rod 201 contracts upward, the slider 402 is reset upward by the slider reset spring 407, and the elastic pressing piece 405 is reset to the initial state by the air pressure and the pressing piece reset spring 406. The electric push rod 201 automatically extends and contracts at regular intervals to repeatedly treat the exhaust gas. S5. When electrocoagulation hemostasis is finished, use the control switch 601 to turn off the coagulation hemostasis head 3, the smoke exhaust fan 403 and the electric push rod 201, and squeeze the outermost vertical end face of the liquid reservoir 501 so that the disinfectant filled inside is sprayed onto the surface of the electrocoagulation hemostasis head 3 through the disinfection nozzle 502. Then, pull down the liquid reservoir 501 and clean the surface of the electrocoagulation hemostasis head 3 with the brush 503. Then, the liquid reservoir 501 is pulled up and reset under the action of the slide bar 504 and the slide bar reset spring 505, and the surface of the electrocoagulation hemostasis head 3 is cleaned again with the brush 503. Repeat the steps of spraying disinfectant and pulling down the liquid reservoir 501 to comprehensively clean the surface of the electrocoagulation hemostasis head 3. Practical application cases

[0032] When a patient is undergoing hepatobiliary and pancreatic surgery and bleeding is found in the patient's blood vessels or organs, the control switch 601 on the handle 6 is used to control the electrocoagulation hemostasis head 3, the smoke exhaust fan 403 and the electric push rod 201 to start, and the electrocoagulation hemostasis head 3 is used to perform electrocoagulation hemostasis treatment on the bleeding part of the patient; Since harmful gas is generated during electrocoagulation hemostasis, the gas is sucked into the main chamber 401 through the air inlet pipe 101 by the smoke exhaust fan 403, filtered by the activated carbon filter layer 404, and then discharged to the external environment through the exhaust hole 102, which is beneficial to protecting the personal safety of the patient and the safety of the surrounding environment; When the electrocoagulation hemostasis treatment is completed, coagulated blood and other contaminants will appear on the surface of the electrocoagulation hemostasis head 3. At this time, the side wall of the liquid reservoir 501 is pressed toward the center, and disinfectant is sprayed on the surface of the electrocoagulation hemostasis head 3 through the disinfection nozzle 502. The liquid reservoir 501 is pulled down as a whole, and the surface of the electrocoagulation hemostasis head 3 is cleaned with a brush 503. Repeat this process multiple times to fully clean the surface of the electrocoagulation hemostasis head 3.
