Description

Technical Field

[0001] This utility model relates to the medical field, specifically to an auxiliary dispersing and fixing device for endoscopic forceps. Background Technology

[0002] In the medical field, endoscopic forceps, surgical forceps, scissors, and other medical instruments require thorough cleaning and disinfection after use to prevent cross-infection. Due to the complex structure of the joints at the tips of these instruments, if the handles are not fully opened to their maximum angle during cleaning, residual blood, tissue fluid, and other contaminants can easily accumulate in the gaps of the joints, leading to ineffective subsequent sterilization. Therefore, the tips of the forceps / scissors must be fully opened during the endoscope cleaning process; however, significant shortcomings still exist in actual implementation: The efficiency of manual clamping: Due to the slender shape of the clamps, conventional operation requires two people: one to open the handles and maintain the open position of the head, and the other to clean them. This method is inefficient and has high labor costs, making it difficult to implement continuously under the high-load operation of a sterilization supply center.

[0003] Cleaning quality controllability and instrument safety: If operated by a single person, there is not only the possibility of oversight, but also the fact that when operating by a single person, one hand holds the handle and the other hand holds the brush to clean, which makes the instrument easy to slip or even bump or fall, which may cause mechanical damage to the precision mating surfaces or other parts.

[0004] To address the aforementioned issues, there is an urgent need to design a device specifically designed for endoscopic forceps cleaning that can assist in opening and fixing the forceps, thereby improving cleaning quality and reducing operational risks. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary opening and fixing device for endoscopic forceps. This device can easily open the head of the endoscopic forceps and stably maintain the opened state. The cleaning operator can operate it alone, freeing up their hands to focus on fixing and cleaning the head of the instrument, effectively improving the cleaning quality of the instrument, increasing the efficiency of the cleaning work, and reducing the damage rate of the instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary retractor and fixator for endoscopic forceps includes a housing, a limiting block, a control button, a fixing component, and a linkage component. The housing is connected to the handle of an existing endoscopic forceps via the fixing component. The handle of the existing endoscopic forceps consists of two rotatably connected grips. The limiting block is movably disposed inside the housing, and the control button is movably disposed on the housing. The linkage component is disposed between the control button and the limiting block. Pressing the control button drives the limiting block to move closer to or away from the connection point of the two grips. The device also includes a locking component for limiting the state of the control button.

[0007] Compared with existing technologies, the endoscopic forceps auxiliary dilatation and fixation device using the above-mentioned technical solution has the following beneficial effects: The auxiliary retractor and fixator for endoscopic forceps of this invention can be fitted onto existing instruments, offering high flexibility and versatility. During use, simply pressing the control button fully retracts the medical forceps / scissors, exposing the joint gaps at the tip for cleaning and disinfection, thus improving cleaning quality. The locking component maintains the open position of the tip, freeing up hands and reducing labor costs. Users can focus on meticulous cleaning of the tip, further enhancing cleaning quality. There's no need to remove one hand to control the handle, eliminating concerns about closure during cleaning and improving efficiency. Furthermore, it significantly reduces the risk of instrument damage.

[0008] Preferably, the linkage assembly includes a movable rod, a connecting rod, and a spring. Two movable rods and two connecting rods are each provided. The two movable rods are located inside the housing and are symmetrically positioned on both sides of the control button. The end of the movable rod facing the control button has an inclined surface, and the sides of the control button have inclined portions adapted to the inclined surfaces. The two ends of the connecting rod are rotatably connected to the movable rod and the limiting block, respectively. The housing has an internal cavity for the movable rod, connecting rod, and limiting block to move. The spring is located on the side of the limiting block away from the movable rod. When the control button moves into the housing, the two movable rods move away from each other, and the locking assembly automatically restricts the current state of the control button. Utilizing the cooperation of the inclined portions and the inclined surfaces, the force of the control button is applied to the movable rod, causing the movable rod to move and drive the connecting rod and the limiting block. Furthermore, the spring's restoring property applies a pushing force to the other side of the limiting block, pushing it towards the grip connection. Combined with the driving action of the connecting rod, this achieves multiple coordination of pushing and pulling forces, increasing the coordination of the linkage assembly's control over the limiting block's displacement.

[0009] Preferably, the locking assembly includes a limiting strip, an elastic element, and an unlocking button. The limiting strip is movably disposed inside the housing, the unlocking button is connected to the limiting strip, and the surface of the unlocking button is exposed to the outside. The side wall of the control button has a locking groove for the limiting strip to enter and exit, and the elastic element is disposed at the end of the limiting strip away from the locking groove. During the displacement process of pressing the control button, the elastic element will push the limiting strip to achieve automatic locking, and cooperate with the exposed unlocking button structure to meet the unlocking requirements.

[0010] Preferably, the locking assembly has at least two sets. Multiple sets of locking assemblies allow for locking the control button at multiple angles, thereby increasing the stability of the head end in the open state.

[0011] Preferably, the surface of the housing is provided with a recessed groove and a countersunk groove. The unlocking button is movable in the recessed groove, and the control button is movable in the countersunk groove. When the control button is pressed and locked, the control button is flush with the plane of the countersunk groove. The recessed groove and countersunk groove are used to prevent the unlocking button and control button from protruding from the outside of the housing, so as to avoid obstructing the cleaning operation and to avoid the risk of damage caused by small protruding structures when bumping into other cleaning tools.

[0012] Preferably, the surface of the unlock button is provided with anti-slip texture, which does not protrude from the plane of the housing. The anti-slip texture prevents subsequent quick unlocking operations, and the concealed structure also prevents the anti-slip texture itself from obstructing or damaging external objects.

[0013] Preferably, the housing is divided into a first half-shell and a second half-shell. Both the first and second half-shells are provided with movable grooves for the handle to swing, and the inner wall of the movable grooves is provided with a damping layer. The fixing component includes an elastic block, a groove, and a button. A limiting block, a control button, a linkage component, and a locking component are all provided on the first half-shell. The first and second half-shells are arranged opposite each other. The elastic block is located on the inner edge of the first half-shell, and the groove is located on the inner edge of the second half-shell. The button is movably located on the side wall of the second half-shell. The button displacement causes the elastic block to disengage from the groove. When the first and second half-shells are closed, they are fixed to the middle of the handle. By directly snapping on or pressing the button, the housing and handle can be quickly assembled or separated, which is convenient and efficient, thus shortening the time spent on assembly or separation. During use, the damping layer slows down or restricts the movement of the handle, and the locking component further enhances the locking effect when the head end is open.

[0014] Preferably, the fixing component is made transparent or semi-transparent. This transparent or semi-transparent structure allows the entire housing to be translucent, making it easy for workers to inspect the handle assembly and its open position, facilitating assembly and clearly indicating the open state.

[0015] Preferably, the housing is detachably connected to a universal rod and a rotating base, and the rotating base has an adsorption seat on the side away from the housing. To further facilitate cleaning, the handle can be positioned or fixed to the cleaning tank or a fixed object in the endoscope cleaning center. If the clamps or scissors are too long, the problem of the handle at the tail end shifting unknowingly and causing bumps and damage can be avoided when focusing on brushing the head end.

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] like Figures 1 to 7 The auxiliary dilatation and fixation device for the endoscopic forceps shown includes a housing 1, a limiting block 2, a control button 3, a fixing component 4 and a linkage component 5, and a locking component 7 for limiting the state of the control button 3.

[0026] It should be noted that the objects fixed by the auxiliary dilatation and fixation device in this case are not limited to endoscopic forceps, but can also be other medical scissor structures, such as hysteroscopic foreign body scissors, sampling forceps, endoscopic grasping forceps, and similar structures. As long as the shape and size of the internal structure can be adapted to meet the cleaning needs of different forceps / scissors, it is suitable.

[0027] The handle 6 of the existing endoscopic forceps is divided into two rotatably connected grips 60, and the housing 1 is connected to the handle 6 of the existing endoscopic forceps through a fixing component 4.

[0028] The housing 1 is divided into a first half-shell 13 and a second half-shell 14. Both the first half-shell 13 and the second half-shell 14 are provided with movable grooves 15 for the handle 60 to swing, and the inner wall of the movable groove 15 is provided with a damping layer.

[0029] The fixing component 4 includes an elastic locking block 40, a slot 41, and a button 42. The limiting block 2, control button 3, linkage component 5, and locking component 7 are all located on the first half-shell 13. The first half-shell 13 and the second half-shell 14 are arranged opposite to each other. The elastic locking block 40 is located on the inner edge of the first half-shell 13, the slot 41 is located on the inner edge of the second half-shell 14, and the button 42 is movably located on the side wall of the second half-shell 14. The button 42 is displaced to drive the elastic locking block 40 to disengage from the slot 41. When the first half-shell 13 and the second half-shell 14 are closed, they are fixed to the middle of the handle 6.

[0030] To increase the connection stability of the first half-shell 13 and the second half-shell 14, the fixing component 4 is provided with at least two sets, which are arranged opposite to the two sides of the shell 1 as a whole.

[0031] To facilitate quick assembly and determine the current degree of opening at the endoscope forceps tip, the fixing component 4 is made transparent or semi-transparent.

[0032] The limiting block 2 is movably located inside the housing 1, the control button 3 is movably located on the housing 1, and the linkage component 5 is located between the control button 3 and the limiting block 2. Pressing the control button 3 drives the limiting block 2 to move closer to or away from the connection point of the two grips 60.

[0033] The linkage assembly 5 includes a movable rod 50, a linkage rod 51, and a spring 52.

[0034] Two movable rods 50 and two connecting rods 51 are provided. The two movable rods 50 are located inside the housing 1 and are symmetrically located on both sides of the control button 3. The end of the movable rod 50 facing the control button 3 is provided with an inclined surface 53. The two sides of the control button 3 are provided with inclined portions 54 adapted to the inclined surface 53. The two ends of the connecting rod 51 are rotatably connected to the movable rod 50 and the limiting block 2, respectively. The housing 1 is provided with an inner cavity 10 for the movable rod 50, the connecting rod 51 and the limiting block 2 to move. The spring member 52 is provided on the side of the limiting block 2 away from the movable rod 50. When the control button 3 moves into the housing 1, the two movable rods 50 move away from each other, and the locking component 7 automatically restricts the current state of the control button 3.

[0035] A solution using only one limiting block 2 and two connecting rods 51, along with the damping layer of the movable groove 15, can meet the requirements of both opening and fixing. In this embodiment, however, there are two limiting blocks 2 and a total of four corresponding connecting rods 51, increasing the convenience of opening both sides of the handle 60 connection simultaneously.

[0036] The locking assembly 7 includes a limiting strip 70, an elastic element 71, and an unlocking button 72. The limiting strip 70 is movably disposed inside the housing 1. The unlocking button 72 is connected to the limiting strip 70, and the surface of the unlocking button 72 is exposed to the outside. The side wall of the control button 3 is provided with a locking groove 73 for the limiting strip 70 to enter and exit. The elastic element 71 is disposed at the end of the limiting strip 70 away from the locking groove 73.

[0037] In this embodiment, the end edge of the limiting strip 70 away from the elastic member 71 is an arc-shaped structure, which makes it easy for the limiting strip 70 to automatically and quickly enter the locking groove 73 when the control button 3 is pressed.

[0038] Furthermore, to enhance the locking effect, the locking component 7 is provided with at least two sets.

[0039] To prevent the control button 3 or the unlock button 72 from protruding from the housing 1 and causing obstruction, the surface of the housing 1 is provided with a recessed groove 11 and a countersunk groove 12. The unlock button 72 moves in the recessed groove 11, and the control button 3 moves in the countersunk groove 12. When the control button 3 is pressed and locked, the control button 3 is flush with the plane of the countersunk groove 12.

[0040] Furthermore, to facilitate unlocking, the surface of the unlocking button 72 is provided with anti-slip texture 74, which does not protrude from the plane of the housing 1.

[0041] Furthermore, to facilitate cleaning, the handle 6 can be positioned or fixed in the cleaning tank of the endoscope cleaning center when needed. Specifically, a universal rod 8 and a rotating base 9 are detachably connected to the housing 1, and an adsorption seat 90 is provided on the side of the rotating base 9 away from the housing 1. In this embodiment, the end of the universal rod 8 away from the rotating base 9 can be secured using an existing structure such as a backpack buckle or tool bag buckle, and the adsorption seat 90 adopts a suction cup-like structure.

[0042] During use, firstly as Figure 6 As shown, by pressing button 42 and pulling the first half-shell 13, the elastic locking block 40 is disengaged from the slot 41, thus separating the first half-shell 13 and the second half-shell 14. Then, the handle 6 is opened appropriately, and the two grips 60 are placed in the two movable slots 15 of the first half-shell 13 respectively. The second half-shell 14 is then closed, and the elastic locking block 40 automatically springs into the slot 41, achieving a temporary assembly of the shell 1 and the handle 6.

[0043] Then, press control button 3, as shown. Figure 5 As shown, due to the guiding effect of the inclined part 54 and the inclined surface 53, part of the force is applied to the movable rod 50, causing the movable rods 50 to move away from each other, forming a shape as shown. Figure 3 and Figure 4 In this state, the movable rod 50 pulls the movable rod 50, and due to the thrust of the spring 52, the limiting block 2 gradually moves closer to the middle of the housing 1, and the two handles 60 gradually open under the push of the limiting block 2.

[0044] like Figure 5As shown in the enlarged view, when the locking groove 73 is displaced to the position of the limiting strip 70, the elastic element 71 pushes the limiting strip 70 to automatically engage in the locking groove 73, thereby locking the state of the control button 3, that is, locking the current open state of the linkage component 5, the limiting block 2, and the handle 6. Combined with the damping layer of the movable groove 15, this further strengthens the open state of the handle 6, allowing the endoscope forceps head to be fully opened and maintained in the open state. After cleaning the head, the unlocking button 72 can be pushed to both sides using the anti-slip texture 74 to release the locking state of the above components, allowing the handle 60 to swing back in the movable groove 15. Then, by opening the fixing components, the first half-shell 13 and the second half-shell 14 can be separated, achieving the separation of the handle 6 and the auxiliary opening and fixing device after cleaning.

[0045] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
