Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical debridement, in particular to a medical debridement flushing device. BACKGROUND

[0002] When cleaning a wound, it is usually necessary to first wash the wound, then disinfect and use a scraper to remove necrotic tissue. However, when using a scraper, it is difficult to distinguish the color and texture of the tissue by the naked eye, and it is often difficult to control whether to remove necrotic tissue and foreign matter in the wound or to avoid damaging healthy tissue, thereby reducing the efficiency of debridement.

[0003] Therefore, there is a need for a debridement device that can improve the efficiency of cleaning a wound. SUMMARY

[0004] The present application aims to provide a medical debridement flushing device to improve the efficiency of cleaning a wound.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a medical debridement flushing device, comprising a strip-shaped shell and a water inlet pipe, the shell comprising a tip, the tip being inverted conical, a plurality of blades being provided on the tip, a water outlet hole being provided at a position corresponding to each blade, the water outlet hole, the interior of the shell and the water inlet pipe being sequentially connected.

[0006] The beneficial effects of the present application are as follows:

[0007] 1. In the prior art, in order to facilitate operation, flushing the wound and removing necrotic tissue are two steps. In the present application, the flushing function and the removal function are combined in one device, avoiding the trouble of switching between a flusher and a scraper, and being convenient and fast.

[0008] 2. For wounds with necrotic tissue and foreign matter, a lot of residues can accumulate on the blades. In order to save the trouble of cleaning the blades during operation, the present application provides a water outlet hole at a position corresponding to each blade, so that physiological saline can be used to flush away the residues under the blades, thereby improving the efficiency of cleaning the wound.

[0009] 3. Necrotic tissue can be divided into coagulation necrosis, liquefaction necrosis and gangrene. The coagulation necrosis tissue is dry and dull, which can be easily distinguished by the naked eye. The liquefaction necrosis tissue can be directly flushed with physiological saline. However, it is difficult to accurately distinguish the gangrene from healthy tissue.

[0010] Gangrene includes dry gangrene with fragile and brittle texture and wet gangrene with soft and paste-like texture. In the present application, physiological saline is used for spraying. Dry gangrene and wet gangrene are more likely to deform during spraying, and the deformation of the tissue can be used to identify dry gangrene and wet gangrene, so as to determine whether the tissue needs to be cleaned. Therefore, the removal and flushing need to be alternately performed, and the spraying is performed where the removal is performed, thereby improving the identification of healthy tissue and necrotic tissue.

[0011] Furthermore, a rotatable inner liner is provided in the shell, and a side water outlet is opened on the inner liner. The inner liner is used to separate the water outlet hole from being connected to the inside of the shell, and the side water outlet is used to connect the water outlet hole and the inside of the shell.

[0012] Furthermore, a first driving member, a slide tube and a positive water outlet cavity are provided in the housing, a first water outlet is provided on the side of the lower end of the slide tube, a positive water outlet portion is provided in the positive water outlet cavity, an insertion groove is provided on the positive water outlet portion, and a second water outlet is provided on the side of the insertion groove, and the driving member is used to drive the lower end of the slide tube to move up and down in the insertion groove;

[0013] When the sliding pipe moves downward, the first water outlet, the second water outlet, the positive water outlet cavity and the water outlet hole are connected in sequence.

[0014] Furthermore, the first driving member includes a first motor, a first gear and a sleeve, the output shaft of the first motor is keyed to the first gear, the first gear is meshed with the outer side of the sleeve, one end of the sleeve is connected to the water inlet pipe, and the inner side of the other end of the sleeve is threadedly connected to the outer side of the sliding tube.

[0015] Furthermore, a first elastic member is provided at the bottom of the insertion groove, and a pressure plate is provided at the upper end of the first elastic member. The pressure plate is used to seal the end of the sliding tube. The insertion groove and the lower end of the sliding tube are clearance-matched and both have rectangular cross-sections.

[0016] Furthermore, a partition of a conical shell is provided on the inner side of the end head, and the positive water outlet passes through the upper end of the partition;

[0017] The positive water outlet is vertically slidably arranged in the housing, a second elastic member is provided between the upper end of the positive water outlet and the housing, and the housing includes a limiting groove. In the initial state, under the pulling force of the second elastic member, the positive water outlet moves upward and abuts against the side wall of the limiting groove;

[0018] At least two card slots are provided on the side of the front water outlet, and a card piece corresponding to the card slot is provided on the inner side of the upper end of the partition. When the card slot and the card piece are engaged, the end head and the rest of the shell are abutted against each other, and the front water outlet, the partition, the front water outlet and the end head are enclosed to form a front water outlet cavity, and the partition, the front water outlet and the inner tank are enclosed to form a side water outlet cavity;

[0019] When the first water outlet and the second water outlet are connected, the first driving member drives the slide tube to continue to move downward, pressing the end head in the opposite direction, the slide tube moves downward relative to the partition and the end head, and the clamping member moves out of the slot; the end head is rotated to dislocate the clamping member and the slot, and then the end head is removed.

[0020] Furthermore, a pressure valve is provided on the side of the sliding tube. When the sliding tube moves upward, the side wall of the insertion groove blocks the second water outlet, the water pressure in the sliding tube rises, and the sliding tube, the pressure valve, the side water outlet cavity, the side water outlet and the water outlet hole are connected in sequence.

[0021] Furthermore, a second driving member is provided in the shell, and the second driving member includes a second motor and a second gear connected by a key. An internal gear is provided on the inner shell, and the second gear is meshed with the internal gear.

[0022] This solution also has the following effects:

[0023] 1. When using a scraper for excision, the angle of the shell often needs to be adjusted according to the actual situation. Especially in the case of deep wounds, it is necessary to close the wound edge and perform the excision at an angle. If the saline can only be sprayed in a single direction, the shell must be rotated at all times to ensure that the side outlet is always facing the skin. This operation is very inconvenient. Medical staff usually hold the shell tightly with their fingers. If the shell is rotated, the fingers are likely to slip, resulting in an unstable grip of the shell, which may cause operational errors.

[0024] In this solution, by rotating the inner liner, the side water outlet is directed toward the skin to be removed, and saline is used for flushing, which is convenient and quick. The button for operating the rotation of the inner liner can be set on the shell, which is convenient and quick to operate.

[0025] 2. The first motor sequentially drives the first gear and the sleeve to rotate, and the sleeve drives the slide tube to slide up and down within the housing; the rectangular cross-section of the insertion slot is used to limit the rotation of the slide rod;

[0026] When the slide tube moves downward, the first water outlet, the second water outlet, the positive water outlet cavity and the water outlet hole are connected in sequence, and the physiological saline is sprayed out from the water outlet hole just below the end;

[0027] When the slide moves upward, the side wall of the insertion groove blocks the second water outlet, and the saline in the slide cannot flow out. The water pressure rises, and the inside of the slide, the pressure valve, the side water outlet cavity, the side water outlet and the water outlet are connected in sequence, and the saline is sprayed out from the water outlet on the side of the end head;

[0028] Thereby, the device can adapt to the situation where the saline solution is sprayed from various angles and avoid the saline solution splashing everywhere.

[0029] 3. The first elastic member is used to ensure that the threads of the sliding tube and the sleeve are tightly pressed together, ensuring that the mechanical transmission can be timely and rapid.

[0030] 4. If the scraper is used improperly, residue will enter the water outlet and then be clamped between the inner liner and the outer shell during the rotation of the inner liner, making it difficult to clean the residue.

[0031] In this solution, the end head is provided with a detachable connection, and the connection position is provided inside the end head, thereby protecting the connection position from failure; but at the same time, in order to facilitate disassembly, the clamping connection can be released by a sliding tube.

[0032] During installation, align the card slot and the card piece, and then install the end head by snapping them together. Since the end head and the shell are against each other, and the positive water outlet part and the side wall of the limit groove are against each other, the end head and the positive water outlet part cannot move upwards. At the same time, the interior of the shell is divided into a positive water outlet chamber and a side water outlet chamber by the partition.

[0033] During disassembly, the sliding tube moves downward until it overcomes the elastic force of the second elastic member, driving the positive water outlet part to move downward relative to the partition part and the end head, thereby releasing the engagement between the slot and the card; but at this time, if the end head is pulled out along the original route, the slot and the card will be re-engaged, so it is necessary to rotate the end head first to dislocate the card and the slot before removing the end head.

Figure 2 As shown, the housing includes a handle body 2 and a tip 5 at the lower end of the handle body 2. The handle body 2 is used for medical personnel to hold with one hand. For ease of display, Figure 2 The hatching is omitted, e.g. Figure 3 As shown, the handle body 2 is provided with a first driving member, a second driving member, a positive water outlet, a sliding tube 3 and an inner liner 6.

[0049] The first driving member includes a first motor 21, a first gear 22 and a sleeve 23. The first motor 21 is bolted to the handle body 2. The first gear 22 and the sleeve 23 are both rotatably connected to the handle body 2. The second driving member in the handle body 2 includes a second motor 24 and a second gear 25 connected by a key. For ease of display, Figure 3 The section lines of the first motor 21 and the second motor 24 are not marked. Figure 3 The specific connection method between the second motor 24, the second gear 25, the first motor 21, the first gear 22, the sleeve 23, and the handle 2 is not shown. This specific connection method is conventional and will not be repeated here. The first motor 21 and the second motor 24 are both servo motors, and the switches of the first motor 21 and the second motor 24 are both located on the handle 2. The output shaft of the first motor 21 is keyed to the first gear 22. The sleeve 23 has external teeth integrally formed on the outside. The first gear 22 meshes with the outside of the sleeve 23. The lower end of the water inlet pipe 1 is inserted into the upper end of the sleeve 23 and communicates with the interior of the sleeve 23. The lower end of the sleeve 23 is internally threaded. The upper end of the slide pipe 3 is inserted into the sleeve 23 and threadedly connected to the sleeve 23.

[0050] like Figure 3 As shown, the space between the handle body 2 and the end head 5 forms a front water outlet cavity 55 and a side water outlet cavity 56. The front water outlet cavity 55 is provided with a front water outlet portion, which includes a connecting pipe 41 and a water outlet pipe 45. The upper portion of the connecting pipe 41 is vertically slidably arranged in the handle body 2, as shown in FIG. Figure 4As shown, a second elastic member 27 is vertically welded between the upper end of the connecting tube 41 and the handle body 2. A limiting groove 26 is defined on the side of the handle body 2 near the connecting tube 41. A limiting protrusion 42 is integrally formed circumferentially on the upper end of the connecting tube 41 and accommodated within the limiting groove 26. A pressure relief valve 43 and a retaining groove 44 are respectively provided on either side of the connecting tube 41. The pressure relief valve 43 extends through the side wall of the connecting tube 41. The retaining groove 44 is positioned below the pressure relief valve 43 and on the outside of the connecting tube 41. The retaining groove 44 is a right-angled trapezoid with the right angle facing downward and the hypotenuse facing upward. The bottom of the water outlet pipe 45 is sealed to form an insertion groove 46, which has a second water outlet 47 formed on its side. A first elastic member 48 is provided at the bottom of the insertion groove 46. A pressure plate 49 is attached to the upper end of the first elastic member 48 to seal the lower end of the slide tube 3. The insertion groove 46 and the lower end of the slide tube 3 are both rectangular in cross-section. Both the second elastic member 27 and the first elastic member 48 are springs.

[0051] The slide tube 3 is made of rigid material and is vertically slidably arranged in the connecting tube 41 and the insertion groove 46. A strip hole and a first water outlet 31 are respectively opened on both sides of the slide tube 3. The strip hole is arranged along the length direction of the slide tube 3 (not shown in the figure). The strip hole is connected to the pressure relief valve 43. The first water outlet 31 is arranged below the strip hole.

[0052] like Figure 3 、 Figure 5 As shown, the end 5 is an inverted conical shell, and a plurality of blades 51 are welded on the end 5. The blade of each blade 51 is facing downward, and a water outlet 52 is provided at a corresponding position below each blade. The water outlet 52 is opened on the end 5, and the water outlet 52, the interior of the shell and the water inlet pipe 1 are connected in sequence; Figure 3 、 Figure 5 As shown, a partition 53 of a conical shell is welded to the inner side of the end 5, and a clamping piece 54 corresponding to the card slot 44 is provided on the inner side of the upper end of the partition 53. The partition 53 has a certain ductility to adapt to the deformation caused by the clamping. When the card slot 44 and the clamping piece 54 are clamped, the end 5 and the handle body 2 are abutted against each other, and the connecting pipe 41, the partition 53, the main water outlet and the end 5 are enclosed to form a main water outlet cavity 55, and the partition 53, the connecting part and the inner tank 6 are enclosed to form a side water outlet cavity 56.

[0053] The inner container 6 is rotatably arranged on the lower side of the handle body 2, as shown in FIG. Figure 6 、 Figure 7 、 Figure 9 As shown, the inner liner 6 is an inverted conical shell that matches the inner shape of the end head 5. The lower side of the inner liner 6 is open, and a through hole 61 is opened on the upper side of the inner liner 6. The connecting pipe 41 of the positive water outlet passes through the through hole 61. An internal gear 62 is welded to the upper edge of the inner liner 6, and the second gear 25 is engaged with the internal gear 62; Figure 6 、 Figure 8As shown, a 45° side water outlet 63 is opened on the side of the inner liner 6. The inner liner 6 is used to separate the water outlet 52 from the interior of the shell, and the side water outlet 63 is used to connect the water outlet 52 and the interior of the shell.

[0054] A method of using a medical debridement and irrigation device is as follows:

[0055] 1. Rotate the inner container 6 so that the side water outlet 63 faces the skin to be removed, rinse with saline solution, and remove with a scraper.

[0056] 2. The first motor 21 drives the first gear 22 and the sleeve 23 to rotate in sequence, and the sleeve 23 drives the slide tube 3 to slide up and down;

[0057] like Figure 10 As shown, when the slide tube 3 moves downward, the first water outlet 31, the second water outlet 47, the positive water outlet cavity 55 and the water outlet hole 52 are connected in sequence, and the physiological saline is sprayed out from the water outlet hole 52 just below the end 5;

[0058] like Figure 3 As shown, when the slide tube 3 moves upward, the side wall of the insertion groove 46 blocks the second water outlet 47, and the saline in the slide tube 3 cannot flow out. The water pressure rises, and the strip hole, the pressure valve, the side water outlet cavity 56, the side water outlet 63 and the water outlet 52 are connected in sequence, and the saline is sprayed out from the water outlet 52 on the side of the end 5;

[0059] 3. In the initial state, under the pulling force of the second elastic member 27, the positive water outlet moves upward, and the limiting protrusion 42 of the connecting pipe 41 and the upper side wall of the limiting groove 26 abut against each other;

[0060] When installing the end head 5, align the card slot 44 and the card member 54, and then install the end head 5 by engaging the card slot 44 and the card member 54; since the end head 5 and the housing are against each other, and the positive water outlet part and the side wall of the limiting groove 26 are against each other, the end head 5 and the positive water outlet part cannot move further upward, thereby fixing the end head 5;

[0061] like Figure 11 As shown, when the end head 5 is removed, the sliding tube 3 moves downward until it overcomes the elastic force of the second elastic member 27, driving the positive water outlet portion to move downward relative to the partition 53 and the end head 5, thereby releasing the engagement between the slot 44 and the clamping member 54; but at this time, if the end head 5 is pulled out along the original route, the slot 44 and the clamping member 54 will be re-engaged, so it is necessary to rotate the end head 5 first to dislocate the clamping member 54 and the slot 44 before removing the end head 5.

[0062] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
