Description

Technical Field

[0001] The present invention relates to the technical field of debridement equipment, and particularly to a combined surgical debridement device. Background Art

[0002] Debridement is to clean and decontaminate a fresh open contaminated wound, remove blood clots and foreign bodies, excise necrotic tissue, suture the wound, minimize contamination as much as possible, and even turn it into a clean wound to achieve primary healing, which is beneficial to the restoration of the function and morphology of the injured part. It mainly includes cleaning the wound, cleaning up the wound, suturing the wound, and dressing the wound.

[0003] Currently, when debriding some small wounds of patients, medical staff will first prepare soapy water, normal saline, 3% hydrogen peroxide, sterile brushes, and several sterile gauzes and gloves required for cleaning the wound. When cleaning the wound, medical staff wear sterile gloves, fold the sterile gauze into the size of the wound, press the gauze with one hand to cover the wound, then hold the sterile brush with the other hand, wipe and clean the skin within the range of 15 cm - 30 cm outside the wound, and at the same time, another medical staff needs to pour soapy water onto the skin outside the wound, clean it three times in a cycle, rinse it with normal saline each time, then uncover the gauze, alternately rinse the wound with normal saline and hydrogen peroxide, and end with normal saline. At this time, the cleaning of the wound is completed. However, in the whole process, at least two medical staff are required to cooperate, and it is impossible to complete the debridement operation alone. When debriding some wounds with a small trauma area, this will undoubtedly occupy more human resources. Therefore, we propose a combined surgical debridement device. Summary of the Invention

[0004] The purpose of the present invention is to provide a combined surgical debridement device that can realize the cleaning process in debridement surgery by a single person, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A combined surgical debridement device includes a driving rod and a grip rotatably sleeved outside the bottom end of the driving rod. The top of the driving rod is rotatably installed with a housing, and two negative pressure adsorption components are installed in the housing. The top of the driving rod is provided with a driving member. The top of the grip is fixed to the bottom of the housing through two docking plates, and an installation shell is fixed to the bottom of the grip. A wiping component for skin cleaning is installed in the installation shell.

[0006] Preferably, the negative pressure adsorption assembly includes a negative pressure cylinder fixed to the inner wall of the housing. A regulating rod is rotatably installed at the top of the negative pressure cylinder, and a spiral blade is fixed to the outer side of the regulating rod. One side of the top of the negative pressure cylinder is fixedly communicated with a water inlet pipe, and the bottom is fixedly communicated with a drain pipe. The spiral blades in the two negative pressure cylinders face in opposite directions. The water source is adsorbed through the negative pressure adsorption assembly and discharged through the drain pipe.

[0007] Preferably, the driving member includes a driving motor fixed to the top of the housing through a motor bracket. The output end of the driving motor is fixedly connected to the top of the driving rod through a coupling, and a driving gear is fixed to the outer side of the driving rod. Transmission gears meshing with the driving gear are fixed to the outer sides of the tops of the regulating rods in the two negative pressure cylinders.

[0008] Preferably, the wiping assembly includes two docking rods fixed in the mounting shell. Mounting plates are slidably sleeved at both ends of the two docking rods, and a sterile brush cloth is attached to the outer side of the mounting plate. A tension spring fixed to the two mounting plates is sleeved on the outer side of the docking rod. The bottom end of the driving rod is rotatably inserted into the mounting shell through a bearing, and a rotating cam fitting with the two mounting plates is fixed to the bottom of the driving rod. The designed wiping assembly can assist in wiping the skin.

[0009] Preferably, docking seats are fixed to both sides of the mounting shell, and the drain pipe is inserted into the docking seats. The designed docking seats can fix the drain pipe on both sides of the mounting shell, so that when the mounting shell is wiping, the water source can directly impact.

[0010] Preferably, a rhombus groove is formed at the bottom end of the driving rod located inside the housing, and a regulating gear is slidably sleeved in the rhombus groove. An adjusting assembly is installed at the bottom of the housing, and an accelerating member is installed in the negative pressure cylinder. The designed accelerating member can adjust the magnitude of the negative pressure in the negative pressure cylinder, so that the water spraying force can be adjusted.

[0011] Preferably, the accelerating member includes a regulating shaft rotatably installed at the bottom of the negative pressure cylinder. The regulating shaft is rotatably inserted into the bottom of the regulating rod, and an accelerating gear meshing with the regulating gear is fixed to the outer side of the regulating rod. A negative pressure wheel is fixed to the outer side of the top of the regulating rod. The designed accelerating member increases the adsorption force in the negative pressure cylinder, making the sprayed water more powerful and facilitating the flushing of dirt.

[0012] Preferably, the adjusting assembly includes a chassis rotatably docked with the bottom of the adjusting gear. An installation ring is fixed to the bottom of the housing, and adjusting plates are rotatably installed on both sides of the installation ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Through the mutual cooperation of the designed negative pressure adsorption assembly and the driving member, the present invention can act as a small negative pressure pump to adsorb the corresponding water source and discharge it through the drain pipe. When cleaning the affected area of the patient, soapy water or physiological saline can be automatically sprayed, enabling a single-handed operation by the operator to simultaneously wipe the outer skin of the affected area, making it more convenient for a single medical staff to perform debridement on the affected area;

[0016] The designed driving member drives the two mounting plates in the bottom wiping assembly to reciprocate, thus simulating the wiping action of a person. The operator only needs to hold the handle and move it, making the wiping during debridement simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 , a combined surgical debridement device shown in the figure, including a driving rod 1 and a grip 5 rotatably sleeved outside the bottom end of the driving rod 1. The top of the driving rod 1 is rotatably installed with an outer shell 2, and two negative pressure adsorption assemblies 3 are installed inside the outer shell 2. A driving member 4 is installed at the top of the driving rod 1. The top of the grip 5 is fixed to the bottom of the outer shell 2 through two docking plates, and an installation shell 6 is fixed to the bottom of the grip 5. A wiping assembly 7 for skin cleaning is installed inside the installation shell 6;

[0028] It should be noted that: during use, the operator holds the grip 5, and then drives the negative pressure adsorption assembly 3 to operate through the driving member 4, so as to adsorb corresponding soapy water or physiological saline, etc. By driving the wiping assembly 7 to operate, when the operator wipes and cleans the skin outside the affected area, soapy water or physiological saline can be sprayed to assist, enabling the wiping operation to be completed with one hand, and the other hand can be used to press the affected area, realizing the cleaning process before debridement by a single person.

[0029] It is worth noting that: the outer shell 2 can be made of transparent plastic to enable the operator to observe the internal situation.

[0030] Among them, please refer to Figures 2-4, in the illustrated negative pressure adsorption assembly 3, it includes a negative pressure cylinder 8 fixed to the inner wall of the housing 2. A regulating rod 9 is rotatably installed at the top of the negative pressure cylinder 8, and a spiral blade 10 is fixed to the outer side of the regulating rod 9. One side of the top of the negative pressure cylinder 8 is fixedly communicated with a water inlet pipe 11, and the bottom is fixedly communicated with a drain pipe 12. The spiral blades 10 in the two negative pressure cylinders 8 face in opposite directions;

[0031] It should be noted that: by rotating the regulating rod 9, the spiral blade 10 is driven to rotate, so that negative pressure is generated in the negative pressure cylinder 8, and soapy water is adsorbed through the water inlet pipe 11 and then discharged through the drain pipe 12.

[0032] It is worth noting that: the spiral blades 10 in the two negative pressure cylinders 8 face in opposite directions, so that when the driving member 4 rotates, only one negative pressure cylinder 8 can be driven to adsorb and drain water, and the other will not drain water in the reverse direction. Therefore, only by the forward and reverse rotation of the driving member 4 can the two negative pressure cylinders 8 be able to correspond to the discharge of two kinds of water.

[0033] It also needs to be explained that: the outer side of the spiral blade 10 fits with the inner wall of the negative pressure cylinder 8, making the adsorption effect on water better.

[0034] In addition, the two drain pipes 12 are inserted into the containers filled with soapy water and physiological saline to provide the supply of water source. At the same time, personnel can also dock a Y-shaped pipe at the outer end of the drain pipe 12 and install a steering valve for docking the two containers to ensure the sufficiency and variety of the water source for various water sources required during the debridement process.

[0035] At the same time, please refer to Figures 2-4 , in the illustrated driving member 4, it includes a driving motor 13 fixed to the top of the housing 2 through a motor bracket. The output end of the driving motor 13 is fixedly connected to the top of the driving rod 1 through a coupling, and a driving gear 14 is fixed to the outer side of the driving rod 1. On the outer sides of the tops of the regulating rods 9 in the two negative pressure cylinders 8, transmission gears 15 meshing with the driving gear 14 are fixedly installed;

[0036] It should be noted that: by the rotation of the driving motor 13, the driving rod 1 is driven to rotate, so that the driving gear 14 rotates correspondingly and drives the two transmission gears 15 to rotate synchronously.

[0037] It is worth noting that: the two transmission gears 15 rotate synchronously. Because the spiral blades 10 face in opposite directions, only one of the negative pressure cylinders 8 can be satisfied to adsorb and discharge the water source.

[0038] In addition, please refer to Figure 6 and Figure 7, in the illustrated wiping assembly 7, there are two docking rods 16 fixed inside the mounting shell 6. Both ends of the two docking rods 16 are slidably sleeved with mounting plates 17, and a sterile brush cloth is attached to the outer side of the mounting plate 17. A tension spring 18 fixed to the two mounting plates 17 is sleeved on the outer side of the docking rod 16. The bottom end of the driving rod 1 is rotatably inserted into the mounting shell 6 through a bearing, and a rotating cam 19 that fits with the two mounting plates 17 is fixed to the bottom of the driving rod 1;

[0039] It should be noted that: by driving the driving rod 1 to rotate through the driving motor 13, the rotating cam 19 at the bottom rotates. At this time, the two mounting plates 17 will be separated in sequence and reset under the action of the tension spring 18, so as to realize the reciprocating movement of the mounting plate 17, which can assist in wiping and effectively wipe the skin outside the affected area clean.

[0040] It is worth noting that: in order for the sterile brush cloth to be a common sterile cloth, the operator can fix a magic tape on the outer side of the mounting plate 17 and bond the sterile brush cloth, so that the sterile brush cloth can be conveniently replaced during multiple cleaning processes in the debridement process, making the operation more convenient.

[0041] It also should be noted that: in order to continuously have water source to wash the skin during skin wiping, the operator fixes docking seats 20 on both sides of the mounting shell 6, and the drain pipe 12 is inserted into the docking seat 20, so that the drain pipe 12 can always be located near the mounting shell 6, facilitating wiping.

[0042] The principle of cleaning the wound in the debridement operation: First, the operator presses a sterile gauze against the wound with one hand, and then holds the grip 5 with the other hand. Before holding the grip 5, the fitting of the sterile brush cloth and the corresponding insertion of the water inlet pipe 11 have been completed. The operator only needs to hold the grip 5 with the driving part 4 already running and then move along the skin near the wound, so that the sterile brush cloth can be wiped in contact. During the wiping process, soapy water is always discharged through the drain pipe 12. After the wiping is completed, the driving motor 13 is reversed to make another drain pipe 12 discharge physiological saline, and the wound is rinsed with physiological saline to end one cleaning. In the second cleaning, the operator replaces the sterile brush cloth correspondingly and then repeats the operation again.

[0043] It also should be noted that: in this solution, the negative pressure adsorption assembly 3 and the wiping assembly 7 designed by the operator meet the cleaning operation in the first step of the debridement operation, enabling a single medical staff to complete it, greatly alleviating the manpower.

[0044] Embodiment 2

[0045] Please refer to Figure 3 and Figure 5, this embodiment further illustrates Example 1. At the bottom end of the drive rod 1 within the housing 2 shown in the figure, a rhombic groove 21 is provided, and an adjusting gear 22 is slidably sleeved within the rhombic groove 21. An adjusting assembly 23 is installed at the bottom of the housing 2, and an accelerating member 24 is installed within the negative pressure cylinder 8;

[0046] It should be noted that: by designing the adjusting gear 22 to be sleeved outside the rhombic groove 21, when the drive rod 1 rotates, it can also drive the corresponding rotation of the adjusting gear 22, and the adjusting gear 22 can move within the rhombic groove 21.

[0047] Among them, please refer to Figure 3 , the accelerating member 24 shown in the figure includes an adjusting shaft 25 rotatably installed at the bottom of the negative pressure cylinder 8. The adjusting shaft 25 is rotatably inserted into the bottom of the adjusting rod 9, and an accelerating gear 26 meshing with the adjusting gear 22 is fixed on the outer side of the adjusting rod 9. A negative pressure wheel 27 is fixed on the outer side of the top of the adjusting rod 9;

[0048] It should be noted that: under the action of the adjusting assembly 23, the accelerating gear 26 and the adjusting gear 22 mesh with each other. At this time, the negative pressure wheel 27 within the negative pressure cylinder 8 will rotate, thereby increasing the negative pressure within the negative pressure cylinder 8, enabling the water discharged from the drain pipe 12 to have a certain impact effect, facilitating cleaning.

[0049] At the same time, please refer to Figure 5 , the adjusting assembly 23 shown in the figure includes a chassis 28 rotatably docked with the bottom of the adjusting gear 22. An installation ring 29 is fixed at the bottom of the housing 2, and adjusting plates 30 are rotatably installed on both sides of the installation ring 29. A sliding opening for the movement of the adjusting plate 30 is provided at the bottom of the housing 2, and a limiting groove 31 for limiting the adjusting plate 30 is provided at the bottom of the chassis 28. A resisting ring 32 is fixed at the position of the drive rod 1 corresponding to the rhombic groove 21, and a docking ring 33 is rotatably docked at the top of the adjusting gear 22. A compression spring 34 that abuts against the resisting ring 32 and the docking ring 33 is sleeved outside the rhombic groove 21;

[0050] It should be noted that: the operator pinches the two adjusting plates 30 and squeezes them into a vertical state, thereby achieving the upward movement of the chassis 28, enabling the adjusting gear 22 to move upward to mesh and dock with the accelerating gear 26. After the adjusting plate 30 is opened, the compression spring 34 can push the docking ring 33 downward, thereby resetting the adjusting gear 22.

[0051] It is worth noting that: after adjusting the adjusting plate 30 to a vertical state, at this time, it will be docked with the limiting groove 31, achieving a docking and limiting effect, making it more stable to maintain the vertical state.

[0052] It should also be noted that: both the docking ring 33 and the abutting ring 32 are rotationally attached to both sides of the adjusting gear 22.

[0053] All other structures are the same as those in Embodiment 1.

[0054] Embodiment 3

[0055] Please refer to Figure 5 , this embodiment further illustrates other embodiments. On both sides of the mounting ring 29 shown in the figure, magnets 35 are installed. The adjusting plates 30 are all made of ferromagnetic iron, and pull plates 36 are fixed to the outer sides of the adjusting plates 30.

[0056] It should be noted that: the designed magnets 35 enable the adjusting plates 30 to maintain a vertical state, and the design of the pull plates 36 mainly facilitates the subsequent opening of the adjusting plates 30.

[0057] All other structures are the same as those in Embodiment 2.

[0058] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
