Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a postoperative cavity volume measuring device. Background Art

[0002] Surgery is a method of treating disease, and doctors usually need to remove lesions from the patient's body to save lives. However, surgery may cause epidermal collapse, the extent of which depends on the size of the removed tissue, thus affecting the appearance. For example, after breast or other tumor resection, due to the large size of the tumor tissue, if the surgical incision is directly sutured, it may cause the epidermis to collapse significantly.

[0003] To avoid this situation, the patient's own tissue (such as fat, etc.) can be used to fill the cavity after resection to effectively prevent the epidermal tissue from sinking, thereby maintaining the beauty of the surgical site.

[0004] However, in actual surgery, doctors cannot directly observe the situation inside the wound, so it is difficult to accurately judge the required filling volume. Doctors usually make judgments based on experience, but this method is not very accurate. If the missing volume is judged to be too large, too much tissue may be removed, causing unnecessary pain and damage to the patient; if the missing volume is judged to be too small, the filling effect may not be ideal. Summary of the invention

Detailed implementation manners

[0059] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art based on this application belong to the scope of protection of the present invention.

[0060] After the diseased tissue is removed from a cancer patient, or after the infected wound is cleaned in an infected patient, a certain volume of cavity will be generated inside the human body due to the removal of some body tissues. By filling the tissue, it is possible to prevent obvious depression of the epidermis. In the existing solutions, doctors can only judge the size of the filling tissue completely based on experience. Therefore, it is difficult to accurately judge the filling volume.

[0061] A postoperative cavity volume measuring device provided by an embodiment of the invention can facilitate a doctor to judge the volume of tissue required to be filled for a patient.

[0062] Figure 1 It is a schematic diagram of the principle structure of the first postoperative cavity volume measuring device provided by an embodiment of the present invention. Figure 2 It is a schematic diagram of the structure of the first postoperative cavity volume measuring device provided by an embodiment of the present invention in an uninflated state. Figure 3 It is a schematic diagram of the structure of the first postoperative cavity volume measuring device provided by an embodiment of the present invention in an inflated state. Please refer to Figures 1 to 3 As shown, a postoperative cavity volume measuring device provided by an embodiment of the present invention includes: a volume simulation bag 10, a fluid pump 20, and a controller 30. The volume simulation bag 10 has a fluid injection interface, and the volume of the volume simulation bag 10 increases as the volume of the fluid injected through the fluid injection interface increases. The fluid pump 20 has a fluid output interface, and the fluid output interface can be detachably connected to the fluid injection interface. The controller 30 is electrically connected to the fluid pump 20 and is used to control the fluid pump 20 to inject fluid with a volume corresponding to the trigger instruction into the volume simulation bag 10 according to the trigger instruction of the user.

[0063] For the postoperative cavity volume measuring device provided by an embodiment of the present invention, the fluid output interface of the fluid pump 20 is detachably connected to the fluid injection interface of the volume simulation bag 10, and the volume of the volume simulation bag 10 increases as the volume of the fluid injected through the fluid injection interface increases. Before filling the tissue volume of a postoperative patient, a doctor can use the postoperative cavity volume measuring device of this solution, place the volume simulation bag 10 in the cavity after the diseased tissue is removed from the patient's body, and manipulate the controller 30 to generate a trigger instruction, which can enable the controller 30 to control the fluid pump 20 to inject fluid with a volume corresponding to the trigger instruction into the volume simulation bag 10, so as to enable the volume simulation bag 10 to simulate the volume of the tissue to be filled. After the measurement is completed, the doctor can judge the size of the tissue volume to be filled for the patient by reading the volume of the fluid injected by the fluid pump 20 into the volume simulation bag 10. Compared with the prior art, it can facilitate the doctor to more accurately judge the volume of tissue required to be filled for a postoperative patient and reduce the probability of filling the postoperative cavity of the patient with tissue of too large or too small a volume.

[0064] In implementation, the fluid pumped out by the fluid pump 20 in the postoperative cavity volume measuring device can be liquid or gas. For example, Figure 2 as shown, when the fluid is gas, the volume simulation bag 10 is in an uninflated state. When a doctor measures the volume of the cavity in a patient's body, the doctor first places the uninflated volume simulation bag 10 into the cavity in the patient's body that needs to be filled with tissue. Then, a trigger command is sent to the controller 30, and the controller 30 can control the fluid pump 20 to inject fluid with a volume corresponding to the trigger command into the volume simulation bag 10. For example, Figure 3 as shown, the volume simulation bag 10 changes from the uninflated state to the inflated state, and the volume of the volume simulation bag 10 increases accordingly. The volume of the volume simulation bag 10 can be the volume of the fluid injected into the volume simulation bag 10 by the fluid pump 20. The doctor can judge the volume of the tissue to be filled by reading the volume of the fluid injected by the fluid pump 20.

[0065] Among them, the volume simulation bag 10 is a sterilized disposable bag. The volume simulation bag 10 is a replaceable device. The fluid injection interface of the volume simulation bag 10 and the fluid output interface of the fluid pump 20 are detachably connected. After use, a new volume simulation bag 10 needs to be replaced for the next use to prevent the volume simulation bag 10 from causing bacterial infection to the patient's body.

[0066] Specifically, the fluid output interface of the fluid pump 20 can be made of a rigid material, such as a metal pipe orifice or a polymer material pipe orifice. The fluid injection interface of the volume simulation bag 10 can be sleeved on the outer wall of the pipe orifice of the fluid output interface and fixed by an elastic rubber ring. After the elastic rubber ring is removed, they can be detachably separated from each other. Or, the fluid injection interface of the volume simulation bag 10 is an elastic connection port with an elastic rubber ring built in. Under the elasticity of the elastic connection port, it can be conveniently detachably connected to the pipe orifice of the fluid output interface.

[0067] The material of the volume simulation bag 10 can be a material with good flexibility, such as a plastic bag, a polymer material bag, a rubber bag or a silicone bag, etc. For example, in some embodiments, the whole volume simulation bag 10 is made of a flexible material or an elastic material. After the fluid is injected into it, the overall volume increases.

[0068] In practice, it is difficult for doctors to insert the entire volume simulation bag 10 into the patient's body in some narrow cavities. The volume of the fluid injected by the fluid pump 20 into the volume simulation bag 10 is equal to the sum of the volume of the fluid in the volume simulation bag 10 inserted into the patient's body and the volume of the fluid in the volume simulation bag 10 not inserted into the patient's body. When the doctor reads the volume of the fluid injected by the fluid pump 20, it actually includes the volume of the fluid in the volume simulation bag 10 not inserted into the patient's body. Therefore, there is a small difference from the actual volume of the fluid injected into the patient's cavity. At this time, the doctor still needs to rely on experience to judge the size of the difference, subtract the judged error value from the volume of the fluid injected by the fluid pump 20 read, and calculate the volume of the tissue to be filled. If the doctor lacks experience, errors may occur in the calculated tissue volume.

[0069] Figure 4 The following is a schematic structural diagram of the second specific postoperative cavity volume measurement device provided by the embodiment of the present invention. Please refer to Figure 4 As shown, in order to reduce errors, in some other embodiments, different from the above embodiments, in this embodiment, the inserted part of the volume simulation bag 10 is made of flexible material or elastic material, and the non-inserted part is made of hard material. Specifically, the volume simulation bag 10 includes an extension pipeline 11 and a simulation bag 12. The fluid injection interface is located at one end of the extension pipeline 11, and the other end of the extension pipeline 11 is communicated with the simulation bag 12; wherein the extension pipeline 11 is made of hard or tough material, and the simulation bag 12 is made of flexible material or elastic material. In a specific implementation, the extension pipeline 11 can be made of thermosetting plastic or plastic pipeline for drip. When the end of the extension pipeline 11 is connected to the metal pipe orifice of the fluid pump 20, the end of the extension pipeline 11 can be sleeved on the outer wall of the metal pipe orifice and fixed by an elastic rubber ring. Of course, in order to improve the sealing performance, docking thread connection interfaces can also be provided at the end of the extension pipeline 11 and the metal pipe orifice of the fluid pump 20 respectively. For example, an external thread interface is provided at the end of the extension pipeline 11, and an internal thread interface is provided at the metal pipe orifice of the fluid pump 20. The detachable connection between the external thread interface and the internal thread interface can achieve a good sealing effect. The simulation bag 12 can be made of thermoplastic plastic or rubber material.

[0070] During the doctor's use, the simulation bag 12 can be inserted into the cavity in the patient's body, and the extension pipeline 11 can be located outside the patient's cavity. After the fluid pump 20 injects fluid into the volume simulation bag 10, since the extension pipeline 11 is made of hard or flexible material, its volume will not change, and only the volume of the simulation bag 12 changes. This makes the volume of the fluid injected by the fluid pump 20 into the volume simulation bag 10 closer to the actual volume of the fluid injected into the patient's cavity.

[0071] In addition, different patients have different conditions (cavity volumes), and thus the volume of tissue to be filled also varies greatly. The volume simulation bag 10 can have different models with different volumes. The volume simulation bag 10 includes multiple models, and different models of volume simulation bags 10 correspond to different maximum fluid volume injection amounts. Therefore, corresponding to different patients, volume simulation bags 10 with different maximum fluid volume injection amounts can be selected at the fluid output interface of the fluid pump 20.

[0072] The fluid pump 20 can be a unidirectional fluid output pump, which can independently realize the function of injecting fluid into the volume simulation bag 10. In some other embodiments, the fluid pump 20 can also be a bidirectional fluid pump, which is used to be controlled by the controller 30 to output fluid or extract fluid to the volume simulation bag 10 through the fluid output interface. That is, the bidirectional fluid pump has the functions of conveying fluid and extracting fluid, and can convey fluid and extract fluid from the volume simulation bag 10 according to the control of the controller 30. When using the postoperative cavity volume measurement device, the doctor can first control the controller 30 to turn on the fluid output function of the fluid pump 20, output fluid to the volume simulation bag 10, and make the volume simulation bag 10 simulate the tissue volume that needs to be filled. Because the volume simulation bag 10 is expanded due to the injection of fluid, it is difficult to take out. In this solution, after completing the measurement, the doctor can control the controller 30 again to turn on the fluid extraction function of the fluid pump to extract the fluid in the expanded volume simulation bag 10, thereby reducing the volume of the volume simulation bag and facilitating the removal of the volume simulation bag 10.

[0073] The operating environment where doctors work is filled with many instruments and equipment, and the environment is limited. If a complex pipeline structure is used, it will be inconvenient to use. Figure 4 As shown, in the implementation of this solution, the postoperative cavity volume measurement device can be constructed in the shape of a gun, with a compact overall structure and easy for doctors to take and use. Figure 5 A schematic diagram of the electrical connection structure of a second specific postoperative cavity volume measurement device provided by an embodiment of the present invention, Figure 6 This is a schematic diagram of the internal structure of the gun body 40 of the third specific postoperative cavity volume measurement device provided by the embodiment of the present invention. Figure 4 , Figure 5 and Figure 6 As shown, the above-mentioned postoperative cavity volume measuring device further includes: a gun body 40 , and the gun body 40 includes a gripping portion 41 and a gun rod portion 42 .

[0074] The interior of the holding part 41 and the gun barrel part 42 has an accommodation space, the fluid pump 20 is arranged in the accommodation space, and the fluid output interface is arranged at the end of the gun barrel part 42. The controller 30 includes: a control circuit 31 and a trigger 32. The control circuit 31 is electrically connected to the fluid pump 20, and the trigger 32 is located on one side of the holding part 41 facing the end of the gun barrel part 42, and is used to trigger the trigger command so that the control circuit 31 controls the fluid pump 20 to inject fluid into the volume simulation bag 10.

[0075] It is easy to understand that in specific implementation, the position of the accommodation space may vary according to the volume of the fluid pump 20 and the size of the structure of the gun body 40. For example, the accommodation space is located in the holding part 41, or the accommodation space is located in the gun barrel part 42.

[0076] Since the postoperative cavity volume measuring device is a compact gun body 40 structure as a whole, when a doctor operates the postoperative cavity volume measuring device, the doctor can directly hold the holding part 41 and pull the trigger 32 to implement the step of injecting fluid into the volume simulation bag 10. The operation is relatively convenient and more suitable for the operating room space in a complex environment.

[0077] In specific implementation, please refer to Figure 5 and Figure 6 As shown, the control circuit 31 includes: a main processor 311 and a switching device 312. The main processor 311 is electrically connected to the fluid pump 20 and the switching device 312 respectively. The switching device 312 is arranged in the accommodation space. When the trigger 32 is pulled, the trigger 32 triggers the switching device 312 to generate the trigger command, and the main processor 311 is used to control the fluid pump 20 to inject fluid into the volume simulation bag 10 according to the trigger command. Among them, in implementation, the main processor 311 and the switching device 312 can be arranged on the same circuit board or on different circuit boards, and the circuit board can be arranged in the accommodation space.

[0078] Specifically, the middle of the trigger 32 is rotatably connected to the gun body 40, and one end of the trigger 32 is exposed outside the gun body 40 for easy pulling by the doctor. When the trigger 32 is in the initial position, the other end of the trigger 32 points to the switching device 312 and does not trigger the switching device 312. After the doctor pulls one end of the trigger 32, the other end of the trigger 32 rotates and can trigger the switching device 312 to make the switching device 312 generate the trigger command. In implementation, a return spring 33 can also be arranged between the other end of the trigger 32 and the inner wall of the gun body 40. After the trigger 32 is pulled, the return spring 33 is compressed, and under the action of the return spring 33, the pulled trigger 32 can return to the initial position.

[0079] The fluid pump 20 injects a volume of fluid into the volume simulation bag 10, which is related to the trigger instruction of the user. Different implementation manners can be adopted.

[0080] For example, the time parameter of the trigger instruction (for example, the time when the doctor pulls the trigger 32) can be associated with the injected volume. The main processor 311 is further configured to identify the time parameter of the trigger instruction, and according to the received trigger instruction, control the fluid pump 20 to inject a fluid volume corresponding to the time parameter into the volume simulation bag 10, where the time parameter is positively correlated with the volume of the fluid injected by the fluid pump 20. That is, the set injection volume per unit time × the time parameter = the volume of the injected fluid. For example, the set injection volume per unit time is 1 ml / s, and the doctor continuously presses the trigger for 5 s. Then the main processor 311 controls the fluid pump 20 to inject 1 ml / s × 5 s, a total of 5 ml of fluid into the volume simulation bag 10, and records the total volume of the injected fluid.

[0081] For another example, the number of times of the trigger instruction (for example, the number of times the doctor pulls the trigger 32) can be associated with the injected volume. The switching device 312 generates a trigger instruction according to one trigger of the trigger 32, where one trigger instruction corresponds to a preset volume of fluid. The main processor 311 is further configured to control the fluid pump 20 to inject a preset volume of fluid into the volume simulation bag 10 according to the received trigger instruction. That is, the preset volume × the number of trigger instructions = the volume of the injected fluid. The parameter of the preset volume is a preset parameter, which can specifically be any one of 1 ml, 2 ml, 3 ml, 4 ml, and 5 ml. Of course, it is easy to understand that the parameter of the preset volume is not limited to the above implementation data. For example, the parameter of the preset volume is 1 ml / time, and the doctor presses the trigger a total of 5 times. Then the main processor 311 controls the fluid pump 20 to inject 1 ml into the volume simulation bag 10 five times, a total of 5 ml of fluid, and records the total volume of the injected fluid.

[0082] It is easy to understand that for the above implementation manners, the time or number of times the doctor pulls the trigger can be determined by continuously observing the change of the skin on the surface of the patient's cavity position. When it is considered that the volume simulation bag 10 is fully filled with the cavity and the flatness of the patient's skin reaches the expectation, the operation of the trigger can be stopped, and the volume of the fluid injected into the volume simulation bag 10 by the fluid pump 20 can be read. When measuring a deep cavity, such as a sinus tract, and the filling state cannot be seen, the doctor can move the simulation bag to feel whether the simulation bag has been in close contact with the surrounding tissues. Close contact means that the injected volume has fully filled the cavity, and loose contact means that the injected volume has not fully filled the cavity.

[0083] In implementation, the parameter of the preset volume can be set by the manufacturer at the factory or can be conveniently set by the doctor to be adjustable. In the adjustable implementation mode, please refer to Figure 4 and Figure 5 As shown, the above-mentioned postoperative cavity volume measuring device further includes: a touch display panel 50. The touch display panel 50 is disposed on the outer surface of the gun body 40, and the touch display panel 50 is electrically connected to the main processor 311.

[0084] As Figure 4 shown, taking the correspondence between the number of trigger instructions (for example, the number of times the doctor pulls the trigger 32) and the injection volume as an example. Among them, the touch display panel 50 can display a preset volume increase button (corresponding to the “+” in Appendix Figure 4 ), a preset volume decrease button (corresponding to the “-” in Appendix Figure 4 ), one trigger instruction corresponds to a fluid of a preset volume (corresponding to the “5 ml / time” in Appendix Figure 4 ), and the main processor 311 is further configured to adjust the preset volume corresponding to one trigger instruction according to the adjustment instruction triggered by the user on the touch display panel 50.

[0085] Specifically, the adjustment instruction can be an increase or decrease instruction. If the doctor triggers the preset volume increase button, the increase or decrease instruction is generated as an increase instruction, and the main processor 311 increases the preset volume by a predetermined unit volume (such as the predetermined unit volume is 1 ml) according to the increase instruction. If the doctor triggers the preset volume decrease button, the increase or decrease instruction is a decrease instruction, and the main processor 311 subtracts the predetermined unit volume from the preset volume according to the decrease instruction.

[0086] As Figure 4 shown, after the preset volume is adjusted to 5 ml / time, that is, when the doctor presses the trigger once, the main processor 311 controls the fluid pump 20 to inject 5 ml of fluid into the volume simulation bag 10.

[0087] Of course, as Figure 4 shown, the touch display panel 50 can not only be used to adjust the preset volume, but also be used to display the preset volume and the total volume of the fluid injected into the volume simulation bag 10 by the fluid pump 20, which is convenient for the doctor to directly view.

[0088] As Figure 4As shown, the fluid volume corresponding to one trigger instruction is 5 ml / time. The doctor presses the trigger 12 times in total. Then, the main processor 311 controls the fluid pump 20 to inject 5 ml of fluid into the volume simulation bag 10 in 12 times, with a total of 60 ml of fluid. The touch display panel 50 can display that the total volume of fluid injected by the fluid pump is 60 ml. According to the preset volume displayed on the touch display panel 50, the doctor can know at any time the volume of the preset fluid corresponding to one trigger instruction, that is, the volume of fluid injected by the fluid pump 20 into the volume simulation bag 10 when the doctor pulls the trigger 32 once. The total volume of fluid injected by the fluid pump 20 into the volume simulation bag 10 displayed on the touch display panel 50 facilitates the doctor to directly view the total volume data injected by the fluid pump 20.

[0089] Of course, in implementation, the adjustment instruction is not limited to the above increase and decrease instructions. The adjustment instruction can also be a data input instruction, and the preset volume is set according to the data parameters corresponding to the data input instruction. For example, if the doctor inputs 3 ml through the touch display panel 50, the preset volume is set to 3 ml, which is the volume of the preset fluid corresponding to one trigger instruction.

[0090] Please refer to Figure 6 As shown, in specific implementation, the fluid pump 20 includes: a pump body 21 and a drainage tube 22. One end of the drainage tube 22 is connected to the outlet of the fluid pump 20 through the accommodation space of the gun barrel part 42, and the fluid output interface is located at the other end of the drainage tube 22 and can be detachably connected to the fluid injection interface of the volume simulation bag 10. In implementation, the fluid output interface is exposed outside the gun barrel part 42, which facilitates the connection between the fluid injection interface of the volume simulation bag 10 and the fluid output interface.

[0091] In specific implementation, the fluid used in the postoperative cavity volume measurement device provided by the embodiment of the present invention can be a liquid. For example, water is used as the fluid injected into the volume simulation bag 10. Please refer to Figure 6 As shown, the pump body 21 can be a liquid pump 201a. The postoperative cavity volume measurement device can also include: a liquid storage tank 202a. The liquid storage tank 202a is arranged in the accommodation space, and the liquid outlet of the liquid storage tank 202a is communicated with the liquid inlet of the liquid pump 201a through a pipeline. The liquid pump 201a can adopt a miniaturized micro liquid pump, such as a micro liquid pump 201a with model mzr-6355, which is convenient for realizing the miniaturization of the volume of the postoperative cavity volume measurement device. The liquid storage tank 202a can include a flexible liquid storage bag made of flexible material. The liquid pump 201a can extract the liquid in the flexible liquid storage bag, and as the liquid in the flexible liquid storage bag decreases, the volume of the flexible liquid storage bag will shrink.

[0092] In the above-mentioned embodiment, the liquid storage tank 202a is disposed in the accommodation space. In practice, the liquid storage tank 202a may also be disposed outside the accommodation space. Figure 7 A schematic diagram of the internal structure of a gun body of a fourth specific postoperative cavity volume measurement device provided by an embodiment of the present invention is shown in FIG. Figure 7 As shown, specifically, the liquid storage tank 202a is arranged outside the accommodating space, the shell of the gun body 40 is provided with a first screwing interface 40a, the liquid outlet of the liquid storage tank is the second screwing interface 203a, the first screwing interface 40a and the second screwing interface 203a are detachably connected, and the first screwing interface 40a is connected to the liquid inlet of the liquid pump 201a through a pipeline to connect the liquid outlet of the liquid storage tank with the liquid inlet of the liquid pump 201a. In this embodiment, the liquid storage tank is made of hard material, and the liquid storage tank connects the first screwing interface 40a and the second screwing interface 203a by screwing, which can realize the connection of the two physical bodies of the liquid storage tank and the gun body 40, and can also connect the liquid outlet of the liquid storage tank with the liquid inlet of the liquid pump 201a by a pipeline, so that the connection and disassembly of the liquid storage tank are relatively convenient, and the liquid storage tank can be easily replaced.

[0093] Typically, in a doctor's operating environment, a water container 60 containing clean water is often available, such as a surgical bowl for holding water. Figure 8 A schematic diagram of the internal structure of a gun body of a fifth specific postoperative cavity volume measurement device provided by an embodiment of the present invention is shown in FIG. Figure 8 As shown, in this embodiment, in order to facilitate the use of the surrounding water container 60, in this embodiment, when the pump body 21 is a liquid pump, the postoperative cavity volume measuring device also includes: a liquid drainage tube 204a, the first port of the liquid drainage tube 204a is arranged in the accommodating space, connected to the liquid inlet of the liquid pump 201a, and the second port of the liquid drainage tube 204a extends to the outside of the accommodating space, serving as the external liquid drainage port of the postoperative cavity volume measuring device. When using the postoperative cavity volume measuring device, the second port of the liquid drainage tube 204a can be placed in a water container 60 filled with clean water, and under the suction of the liquid pump, the liquid in the water container 60 can be transported to the volume simulation bag 10 through the liquid drainage tube 204a.

[0094] Among them, the liquid pump can be a bidirectional liquid pump. After completing the measurement, the doctor can control the controller to turn on the liquid extraction function of the bidirectional liquid pump to extract the liquid in the expanded volume simulation bag, thereby reducing the volume of the volume simulation bag and facilitating the removal of the volume simulation bag.

[0095] The fluid used in the postoperative cavity volume measurement device provided in the embodiment of the present invention may also be gas, for example, air is used as the fluid injected into the volume simulation bag 10. In a specific implementation,Figure 9 The following is a schematic diagram of the internal structure of the gun body of the sixth specific postoperative cavity volume measurement device provided by the embodiments of the present invention. Please refer to Figure 9 as shown. The pump body 21 can be an air pump 201b. When the pump body 21 is an air pump 201b, a through hole 202b is provided on the outer wall of the gun body 40. The air inlet of the air pump 201b is communicated with the through hole 202b. When a doctor uses the postoperative cavity volume measurement device with the air pump 201b, the cavity of the patient can be measured.

[0096] Please refer to Figure 9 as shown. Further, in order to improve the safety and reliability of the postoperative cavity volume measurement device with the air pump 201b, a microporous filter 203b is also provided on the outer wall of the gun body 40. The microporous filter 203b covers the through hole 202b and is used to filter the air flowing through the through hole 202b. The microporous filter 203b can make the air injected into the volume simulation bag 10 be clean filtered air. When the doctor places the volume simulation bag 10 in the patient's body, if the volume simulation bag 10 leaks, the patient will not be infected because unclean air is injected into the volume simulation bag 10.

[0097] In a specific implementation, the filtration aperture of the microporous filter 203b can be between 0.45 microns and 0.2 microns. For example, the filtration aperture of the microporous filter 203b can be 0.45 microns or 0.2 microns.

[0098] In addition, for the convenience of replacement, the microporous filter 203b can be detachably connected to the outer wall of the gun body 40.

[0099] A through hole 202b is provided on the outer wall of the gun body 40, and the air inlet of the air pump 201b is communicated with the through hole 202b. The air pump 201b can be a miniaturized micro air pump 201b. For example, a micro piezoelectric air pump 201b of model MAC2011A is used, which is convenient to realize the miniaturization of the volume of the postoperative cavity volume measurement device. The through hole 202b can be one or multiple. The through hole 202b can be arranged at a position opposite to the air inlet of the air pump 201b, but is not limited thereto. The main processor 311 controls the air pump 201b to inject gas into the volume simulation bag 10.

[0100] Among them, the air pump can be a two-way air pump. After the measurement is completed, the doctor can control the controller again to turn on the gas extraction function of the two-way air pump to extract the gas in the inflated volume simulation bag, so that the volume of the volume simulation bag can be reduced, which is convenient to take out the volume simulation bag.

[0101] In the above embodiments, the overall postoperative cavity volume measuring device can be implemented in the structure of a gun body. It is easy to understand that in the implementation of this solution, it is not limited to the use of a gun body structure, and the fluid pump is implemented in an "external" manner. Figure 10 The following is a schematic structural diagram of the seventh specific postoperative cavity volume measuring device provided by the embodiment of the present invention, as Figure 10 shown. In implementation, the fluid pump includes: a pump body 21 and a drainage extension tube 23. The first end of the drainage extension tube 23 communicates with the output port of the pump body 21, and the fluid output interface is located at the second end of the drainage extension tube 23.

[0102] Specifically, the fluid pump can be implemented using an air pump or a liquid pump. Taking the liquid pump as an example, an extension pipeline can be connected to the input interface of the fluid pump to suck liquid from the water container 60. The controller 30 can be electrically connected to the fluid pump using an extended wire, and the control panel of the controller 30 can be provided with control buttons 34 for controlling the operation of the fluid pump.

[0103] Currently, after breast or other tumor resection, clinicians lack tools to measure the cavity volume and cannot accurately estimate the volume of tissue required. Therefore, there are certain difficulties in using autologous fat or other tissues to fill the cavity formed after surgery. Taking too much autologous tissue for filling may cause additional trauma to the patient, while too little filling may result in poor effects. In addition, overfilling the sinus tract wound surface will slow down the cell infiltration rate and affect the recovery process.

[0104] To solve this problem, the present invention proposes a postoperative cavity volume measuring device. By filling the volume simulation bag with gas or liquid to measure the volume of the cavity, it helps doctors more accurately judge the volume of tissue required. In this way, medical staff can better judge the use of filling materials and reduce the risks of underfilling and overfilling. It can not only ensure the aesthetic effect of the surgical site after the patient's operation, but also promote the cell infiltration and healing speed. The embodiment of the present invention solves the problem that the cavity volume caused by surgery or infection debridement cannot be measured, and improves the accuracy of medical staff's judgment of the cavity volume.

[0105] In the above embodiments, it can be implemented in whole or in part by software, hardware, firmware, or any combination thereof. When implemented using software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded and executed on a computer, the processes or functions described in the embodiments of the present invention are generated in whole or in part. The computer can be a general-purpose computer, a special-purpose computer, a computer network, or other programmable devices. The computer instructions can be stored in a computer-readable storage medium, or transmitted from one computer-readable storage medium to another. For example, the computer instructions can be transmitted from a website, computer, server, or data center to another website, computer, server, or data center by wire (such as coaxial cable, optical fiber, digital subscriber line (DSL)) or wireless (such as infrared, wireless, microwave, etc.). The computer-readable storage medium can be any available medium that can be accessed by a computer, or a data storage device such as a server or data center that includes one or more integrated available media. The available medium can be a magnetic medium (such as a floppy disk, hard disk, magnetic tape), an optical medium (such as a DVD), or a semiconductor medium (such as a solid state disk (SSD)).
