Description

Technical Field

[0001] This application relates to the field of surgical tools, and in particular to a medical forceps. Background Technology

[0002] Tweezers are grasping tools commonly used in surgical procedures. They typically consist of two metal arms connected by a spring or hinge. The user squeezes the two arms to allow the gripping parts, or tips, to grasp an object.

[0003] Depending on their purpose and design, tweezers can be divided into medical tweezers, electronic component tweezers, beauty tweezers, laboratory tweezers, and jewelry tweezers, etc. However, regardless of the type of tweezers, they are essentially about applying force to the two arms of the tweezers to grasp objects. Therefore, the problem of applying force is inevitable. It is possible that if too much force is applied, the object being grasped may be damaged or the tweezers may be deformed. It is also possible that if too little force is applied, the grasp may be unstable or even fall off.

[0004] When using medical forceps to grasp biological tissues, the same forceps usually require different clamping forces for different objects. This is very difficult for inexperienced users and requires a long period of practice to master the clamping skills. In addition, the clamping force required varies depending on the location of the force application, which further increases the difficulty of applying the appropriate clamping force when using forceps.

In one embodiment of this application, a medical forceps includes a first arm and a second arm; the first arm includes a first connecting portion, a first body, and a first gripping portion connected in sequence; the second arm includes a second connecting portion, a second body, and a second gripping portion connected in sequence, and the second connecting portion is connected to the first connecting portion so that the second gripping portion and the first gripping portion form an elastic clamping position; the first arm also includes a first force control area disposed on the first body, and along a first length direction of the first body, the first force control area is provided with at least two protrusions, and when the medical forceps is in a clamping state, at least one of the protrusions is configured to abut against the second body. The aforementioned medical forceps, through the cooperation of a first body, a first connecting part, a first gripping part, a second body, a second connecting part, and a second gripping part on two arms, cleverly incorporates at least two protrusions arranged along the first length direction of the first body. This design provides appropriate feedback on gripping force at different force application positions, making it suitable for gripping objects of various masses or sizes. Furthermore, it allows for quick and accurate gripping of various objects without requiring extensive practice, greatly reducing the difficulty of applying appropriate gripping force when using medical forceps. Additionally, the optimized design of the protrusions facilitates the secure gripping of various objects, enhancing the applicability of the medical forceps, especially suitable for gripping various tissues during surgical procedures. The following section will further elaborate on this design. Figures 1 to 9 The medical tweezers will now be described in detail.

[0046] In some embodiments, a medical forceps 300, such as Figure 1 As shown, it includes a first arm 100 and a second arm 200; combined with Figure 2The first arm 100 includes a first connecting portion 120, a first body 110, and a first gripping portion 130 connected in sequence; the second arm 200 includes a second connecting portion 220, a second body 210, and a second gripping portion 230 connected in sequence, and the second connecting portion 220 is connected to the first connecting portion 120 so that the second gripping portion 230 and the first gripping portion 130 form an elastic gripping position 310; the first arm 100 also includes a first force control area 140 disposed on the first body 110, and along the first length direction 112 of the first body 110, the first force control area 140 is provided with at least two protrusions, and when the medical tweezers 300 is in the gripping state, at least one of the protrusions is configured to abut against the second body 210. This design, through the cooperation of the first body 110, the first connecting part 120, the first gripping part 130, the second body 210, the second connecting part 220, and the second gripping part 230 of the two arms, cleverly incorporates at least two protrusions arranged along the first length direction 112 of the first body 110. This allows for appropriate feedback on the gripping force at different force application positions. On the one hand, it is suitable for gripping objects of various masses or sizes. On the other hand, it allows for quick and accurate gripping of various objects without the need for extensive practice, greatly reducing the difficulty of applying appropriate gripping force when using medical forceps 300. Furthermore, the optimized design of the protrusions facilitates the secure gripping of various objects, thereby improving the applicability of medical forceps 300, especially suitable for gripping various tissues in surgical procedures.

[0047] In some embodiments, the medical forceps 300 are surgical forceps. In other embodiments, if necessary, the medical forceps 300 can also be used as general medical forceps or medical laboratory forceps, etc. In various embodiments, such as Figure 1 and Figure 2 As shown, the first arm 100 includes a first connecting part 120, a first body 110 and a first gripping part 130 connected in sequence. That is, the first gripping part 130 is connected to the first connecting part 120 through the first body 110. The first gripping part 130 can also be called a tweezers, which is used to cooperate with the second gripping part 230 to contact the object being gripped and apply force to the object being gripped when gripping various objects, thereby gripping the object being gripped. Figure 1 and Figure 2In the illustrated embodiment, the first body 110, the first connecting portion 120, and the first gripping portion 130 are integrally formed; in other embodiments, the first connecting portion 120, the first body 110, and the first gripping portion 130 are sequentially inserted, snapped, welded, or screwed together. This structural design provides appropriate feedback on gripping force at different force application positions, adapting to objects of varying weights and sizes, and allowing for quick and accurate gripping without extensive practice, significantly reducing the difficulty of applying appropriate gripping force. Through optimized design of the protrusions, it can also reliably grip various objects, effectively enhancing the specialization of the medical tweezers 300 in surgical applications. When necessary, it can also be used in general medical procedures, electronic components, beauty treatments, laboratories, and jewelry settings.

[0048] In each embodiment, the second arm 200 includes a second connecting part 220, a second body 210, and a second gripping part 230 connected in sequence. That is, the second gripping part 230 is connected to the second connecting part 220 through the second body 210, and the second connecting part 220 is connected to the first connecting part 120 so that the second gripping part 230 and the first gripping part 130 form an elastic gripping position 310. The elastic gripping position 310 is formed by the connected first arm 100 and the second arm 200, which is a conventional design of medical forceps 300 and will not be described in detail here. Figure 1 and Figure 2 In the illustrated embodiment, the second body 210, the second connecting portion 220, and the second clamping portion 230 are integrally formed; in other embodiments, the second connecting portion 220, the second body 210, and the second clamping portion 230 are sequentially inserted, snapped, welded, or screwed together. Figure 1 and Figure 2 In the illustrated embodiment, the first body 110, the first connecting portion 120, and the first clamping portion 130 are integrally formed, and the second body 210, the second connecting portion 220, and the second clamping portion 230 are integrally formed. As an example, the second connecting portion 220 is snap-fitted, welded, or screwed to the first connecting portion 120; or as... Figure 3As shown, in some embodiments, the first connecting portion 120 and the second connecting portion 220 are integrally formed, that is, the first body 110, the first connecting portion 120, the first gripping portion 130, the second body 210, the second connecting portion 220, and the second gripping portion 230 are integrally formed. This structural design can provide appropriate feedback on the gripping force at different force application positions, adapting to objects of different masses or sizes, allowing for quick and accurate gripping without long-term practice, reducing the difficulty of applying appropriate gripping force; through the optimized design of the protrusion, various objects can be gripped securely, and the connection method between the second arm 200 and the first arm 100 includes integral setting, plug-in, snap-fit, etc., improving the applicability and structural flexibility of the medical forceps 300 in multiple scenarios such as medical surgery and general medical operations.

[0049] In various embodiments, the first arm 100 further includes a first force control area 140 disposed on the first body 110. Along the first length direction 112 of the first body 110, the first force control area 140 is provided with at least two protrusions, and when the medical tweezers 300 is in a clamping state, at least one of the protrusions is configured to abut against the second body 210. Figure 1 and Figure 2In the illustrated embodiment, there are two protrusions, namely a first protrusion 141 and a second protrusion 142. The user can apply force to the first arm 100 and the second arm 200 through the two protrusions or other positions on the first force control area 140 of the first body 110 to clamp the object until at least one of the first protrusions 141 and the second protrusion 142 abuts against the second body 210. The user can easily perceive sufficient force applied to the object being clamped, and can quickly and accurately clamp various objects without extensive practice, thus greatly reducing the difficulty of applying appropriate clamping force when using medical tweezers 300. This structural design, on the one hand, arranges the protrusions along the first length direction 112, forming different force application points. When the user applies force at different positions in the first force control area 140, the degree of contact between the protrusion and the second body 210 will produce differentiated feedback—for example, when the force is small, only one protrusion may contact, while when the force increases, multiple protrusions will contact in sequence. This clearly transmits the clamping force information through physical touch, preventing the object from slipping due to insufficient force or being damaged due to excessive force. On the other hand, traditional tweezers require long-term practice to master force control, while this embodiment uses tactile cues from the contact of the protrusions to allow the user to judge whether the force is sufficient without relying on experience. For example, when the first protrusion 141 contacts, the user can intuitively feel that a light clamping is sufficient for small objects; when the second protrusion 142 also participates in the contact, it can be determined that a heavy clamping is suitable for large objects. This tactile feedback mechanism greatly shortens the learning cycle. On the other hand, by optimizing the number and position of the protrusions, such as the spacing design between two protrusions, the medical forceps 300 can be adapted to objects of different sizes. For example, when clamping blood vessels or nerves in medical surgery, a single protrusion can provide a light force to complete the precise operation; or when assembling electronic components, the two protrusions work together to provide a stable clamping force; or when clamping heavy containers in the laboratory, the mechanical stop formed by the protrusions can prevent the force from decreasing due to arm fatigue. On the other hand, the contact surface between the protrusions and the second body 210 can be designed with anti-slip texture or a flexible end. Combined with the conventional design of the elastic clamping position 310, a composite clamping structure combining elastic tension and rigid contact is formed. This structure adapts to the shape of the object by utilizing elastic deformation and prevents excessive deformation by the protrusions, thereby reducing the risk of objects slipping in scenarios such as surgery where clamping stability is critical. Furthermore, this design, which visualizes mechanical feedback and modularizes operational logic, enables the Medical Forceps 300 to break away from the reliance on user experience in traditional tools. Through structural innovation, it achieves adaptive force control, fundamentally improving the efficiency and reliability of operations in different fields.

[0050] For medical forceps 300 that require maintaining the same clamping force, in some embodiments, the protrusion heights of each of the protrusions are set to be the same. This ensures that when the medical forceps 300 is in the clamping state, the distance 320 between the first body 110 and the second body 210 remains consistent. Consequently, the elastic clamping position 310 formed by the second gripping part 230 and the first gripping part 130 maintains the same width, i.e., the width of the elastic clamping position 310 formed by the second gripping part 230 and the first gripping part 130 is constant. This structural design, through the consistency of the protrusion heights, ensures stable force feedback during clamping, avoiding fluctuations in clamping force due to changes in distance. It is suitable for scenarios requiring high uniformity of clamping force, such as the operation of precision electronic components and tissue clamping in medical surgery. It can effectively improve clamping accuracy and stability, and reduce the risk of object damage or slippage caused by uneven force.

[0051] For medical forceps 300 that require varying clamping forces, in some embodiments, the height of each protrusion decreases as it moves further away from the first connecting portion 120. This allows the first body 110 to deform more significantly at locations further from the first connecting portion 120, thereby reducing the distance 320 between the first body 110 and the second body 210. This results in a relatively smaller width for the elastic clamping position 310 formed by the second gripping portion 230 and the first gripping portion 130, increasing the pressure, i.e., the clamping force, on the object being clamped at the elastic clamping position 310. This structural design, on the one hand, allows the height of the protrusion to decrease with distance from the first connecting portion 120, giving the first body 110 greater deformation space at its distal end. When the user applies force at different locations, the lower height of the distal protrusion allows the first body 110 to bend more elastically towards the second body 210, further reducing the distance 320 and compressing the width of the elastic clamping position 310. According to the principles of mechanics, reducing the width of the elastic clamping position 310 directly increases the pressure on the clamped object, thus achieving a dynamic adjustment effect where the clamping force increases as the force is applied further out. On the other hand, the higher height of the protrusion near the first connecting part 120 restricts the deformation of the body, maintaining a wider spacing between the elastic clamping positions 310. This is suitable for clamping fragile objects such as nerve tissue or ultra-thin chips, preventing damage from excessive force. Furthermore, the lower height of the protrusion further away from the connecting part releases space for body deformation, reducing the width of the elastic clamping position 310 and allowing for greater clamping force on heavy objects, preventing slippage. Moreover, users do not need to consciously control the force; they can intuitively adjust the clamping force simply by changing the force application position, such as moving it closer to or further away from the connecting part. For example, the closer the force application point is to the far end, the lower the height of the protrusion, the greater the body deformation, and the stronger the clamping force. This linear correspondence between position and force transforms abstract force control into a perceptible spatial operation, reducing reliance on user experience and making it particularly suitable for beginners or scenarios requiring rapid switching of operating modes. On the other hand, the gradient-height protrusions essentially provide graded limits for the elastic deformation of the body. Specifically, the higher protrusions provide rigid support at the proximal end to prevent excessive deformation, while the lower protrusions allow for moderate deformation at the distal end to avoid clamping failure due to insufficient force. This design, while ensuring structural stability, optimizes the mechanical transmission path, making the clamping force more uniform and controllable as the force application position changes, reducing the risk of object detachment due to sudden changes in force. Thus, the medical forceps 300 can quickly match the optimal clamping force through simple force application position adjustments in various surgical scenarios with different requirements for force precision, combining ease of operation with functional adaptability.

[0052] For medical tweezers 300 that require control of the user's force application, in some embodiments, the height of each protrusion forms an increasing sequence from near to far from the first connecting portion 120. That is, the closer the protrusion is to the first connecting portion 120, the smaller its height; and the farther away the protrusion is from the first connecting portion 120, the larger its height. This forms two clamping states: one clamping state is that the elastic clamping position 310 has the same width, that is, the same clamping force is maintained at the elastic clamping position 310; the other clamping state is that the elastic clamping position 310 has the same increasing trend as the increasing sequence, that is, the farther away the protrusion is from the first connecting portion 120, the wider the elastic clamping position 310 is under force, so as to clamp larger objects. This structural design allows for several advantages. First, the height of the protrusion increases with distance from the first connecting part 120, creating a stroke limiting gradient. When force is applied near the protrusion, the small height of the protrusion limits the deformation of the first body 110, allowing the elastic clamping position 310 to quickly shrink to a smaller width, suitable for short-stroke, light-force clamping. Second, when force is applied far from the protrusion, the large height of the protrusion limits excessive deformation of the body, allowing the width of the elastic clamping position 310 to expand to a larger size, corresponding to long-stroke, strong clamping. This design transforms the force application stroke into a quantifiable spatial position, achieving a linear mapping between position and stroke through the height difference of the protrusion, thus avoiding sudden changes in clamping force caused by uncontrolled force application stroke. On the other hand, it can also achieve adaptive switching between dual-mode clamping states. For example, in the equal-width clamping mode, the elastic clamping position 310 can maintain a constant width by abutting the second body 210 through a combination of specific protrusions, which is suitable for scenarios that require stable clamping force and ensures uniform force. Or in the incrementally wide clamping mode, the limiting effect of the high protrusion at the far end is used to make the width of the elastic clamping position 310 increase as the force application position moves outward, which can adapt to objects of different sizes. For example, the low protrusion at the near end is used when clamping small objects, and the high protrusion at the far end is switched when clamping large objects. The clamping range is automatically adjusted through the physical structure to reduce the frequency of tool changing. On the other hand, such a structure is conducive to enhanced compatibility in multiple operating scenarios. For example, in precision operation scenarios, the low protrusion at the proximal end allows for small-amplitude and precise force application, avoiding force dispersion caused by an excessively wide elastic clamping position 310, which is suitable for clamping micron-sized components or delicate tissues. In large object clamping scenarios, the high protrusion at the distal end limits excessive deformation of the body, allowing the width of the elastic clamping position 310 to increase linearly with demand, which can stably clamp large objects and prevent objects from slipping due to insufficient clamping range. It can also dynamically adjust the scenario, allowing users to seamlessly switch between fine clamping and strong clamping modes by moving the force application point on the same medical forceps 300, which is especially suitable for complex operations that require frequent adjustment of clamping force, such as in surgical procedures involving complex biological tissues.On the other hand, in this embodiment, the progressively higher protrusions are essentially physical cues for force and stroke. When the point of force application is close to the connecting part, the protrusion is low, the feel is easy, and it indicates light force and short stroke. When the point of force application is far from the connecting part, the protrusion is high, the resistance increases, and it indicates strong force and long stroke. It can be seen that this design transforms abstract force control into perceptible tactile feedback, reducing the cognitive load of the operator on force control. It is especially suitable for beginners to quickly master the force application skills in different scenarios, while reducing the fatigue of professional operators.

[0053] In some of these embodiments, such as Figure 4 As shown, the second arm 200 further includes a second force control area 240, which is disposed on the second body 210; when the medical forceps 300 is in a clamping state, at least one of the protrusions is configured to abut against the second force control area 240 on the second body 210. That is, the first arm 100 includes a first force control area 140 disposed on the first body 110, and along the first length direction 112 of the first body 110, the first force control area 140 has at least two protrusions, and when the medical forceps 300 is in a clamping state, at least one of the protrusions is configured to abut against the second body 210; and the second arm 200 includes a second force control area 240, which is disposed on the second body 210; when the medical forceps 300 is in a clamping state, at least one of the protrusions is configured to abut against the second force control area 240 on the second body 210. As an example, Figure 1 and Figure 2 In the illustrated embodiment, the first force control zone 140 is integrally formed with the first body 110. As an example, Figure 4 In the illustrated embodiment, the first force control area 140 and the second force control area 240 are respectively sleeved on the first Figure 4 The illustrated embodiment is located on body 110 and the second body 210. Another embodiment of the medical forceps 300 is, for example... Figure 5 As shown, with Figure 4Unlike the illustrated embodiment, the first arm 100 and the second arm 200 are connected to the first connecting part 120 via the second connecting part 220, rather than being integrally formed. This structural design has several advantages. First, during clamping, the protrusion abuts against the second force control area 240, allowing the user to simultaneously perceive the clamping force through both force control areas, avoiding force deviation caused by unilateral force application and improving operational accuracy. Second, it expands operational compatibility, adapting to both left- and right-handed operation and single / double-handed force application scenarios. Force applied by the left hand can be fed back through the second force control area 240, and when both hands apply force together, a symmetrical clamping force can be formed, suitable for precision operations or clamping hard objects. Third, the force control area can be modularly designed, such as being fitted onto the main body, facilitating module replacement for different scenarios such as medical and industrial applications, enhancing structural flexibility. Finally, the force application point can be switched between the two force control areas, alleviating fatigue in a single area, and maintaining clamping stability through alternating force application during prolonged operation.

[0054] In some of these embodiments, such as Figure 6 As shown, along the second length direction 212 of the second body 210, the second force control area 240 is provided with at least two positioning parts, each positioning part corresponding to each of the protrusions. One of the positioning parts is configured to position and abut against the corresponding protrusion when the medical forceps 300 is in the clamping state. As an example, Figure 6In the illustrated embodiment, along the first length direction 112 of the first body 110, the first force control area 140 is provided with a first protrusion 141 and a second protrusion 142 of the same height and size; along the second length direction 212 of the second body 210, the second force control area 240 is provided with a first positioning part 241 and a second positioning part 242 of the same height and size; when the medical forceps 300 is in the clamping state, the first positioning part 241 is positioned to abut against the corresponding first protrusion 141, or the second positioning part 242 is positioned to abut against the corresponding second protrusion 142. As an example, the first length direction 112 and the second length direction 212 are parallel. As an example, the positioning part can also be replaced by a protrusion, that is, the first force control area 140 has at least two A protrusions, and the second force control area 240 has at least two B protrusions. Each B protrusion corresponds to each A protrusion, and one of the B protrusions is configured to position and abut against the corresponding A protrusion when the medical forceps 300 is in the clamping state. As an example, the positioning part can also be replaced by a groove, recess, or hole, that is, the first force control area 140 has at least two protrusions, and the second force control area 240 has at least two grooves, recesses, or holes. Each groove, recess, or hole corresponds to each protrusion, and one of the grooves, recesses, or holes is configured to position and abut against the corresponding protrusion when the medical forceps 300 is in the clamping state. This structural design ensures that, on the one hand, the positioning parts and protrusions abut against each other in a one-to-one correspondence. For example, the first positioning part 241 abuts against the first protrusion 141, forming a mechanical positioning point during clamping. This ensures that the relative positions of the first arm 100 and the second arm 200 are fixed, preventing the elastic clamping position 310 from shifting due to force deviation. For instance, when clamping precision electronic components, the engagement between the positioning parts and the protrusions prevents damage to the components due to clamping misalignment. On the other hand, the corresponding positioning parts and protrusions form a fixed distance 320, making the width variation of the elastic clamping position 310 and the force application position quantifiable. By sensing the contact feel of different positioning parts, such as light force when the first positioning part abuts and strong force when the second positioning part abuts, users can quickly master the standardized force control logic, reducing the learning cost of operation. On the other hand, the positioning part can adopt various forms such as protrusions, grooves, and holes, for example, a groove can replace the positioning part, to adapt to different materials and precision requirements. The groove design can enhance anti-slip properties and is suitable for clamping smooth objects; the hole design can form a snap-fit ​​with the protrusion, improving structural stability in heavy-duty scenarios. On the other hand, by selecting different abutment combinations of positioning parts and protrusions, such as the first group for small objects and the second group for large objects, the fine clamping and strong clamping modes can be quickly switched on the same tweezers without changing tools. Moreover, the corresponding abutment of the positioning part and the protrusion forms a rigid transmission path, which can avoid the force attenuation caused by the offset of the force application point of the elastic clamping position 310.For example, in medical surgery, the positioning structure can ensure that the clamping force is evenly transmitted to the forceps tip, including the first clamping part 130 and the second clamping part 230, reducing the problem of excessive local pressure when clamping tissue.

[0055] In some of these embodiments, such as Figure 7 As shown, there are three protrusions, including a first protrusion 141, a second protrusion 142, and a third protrusion 143; in other embodiments, the number of protrusions may also be other, such as four or more, depending on actual needs.

[0056] In some of these embodiments, such as Figure 7 As shown, the second arm portion 200 further includes a bending and clearance structure 250, through which the second body 210 is connected to the second connecting portion 220, thereby increasing the distance 320 between the second body 210 and the first body 110. In other embodiments, such as... Figure 8 As shown, the second arm 200 does not have a bending avoidance structure 250, and the second body 210 is directly connected to the second connecting part 220. In specific applications, the bending avoidance structure 250 can be set according to actual needs. This structural design has two advantages. First, the bending avoidance structure 250 increases the distance 320 between the two bodies by changing the connection angle of the second body 210, providing more operating space for clamping large objects. For example, when clamping large containers such as laboratory beakers, it avoids clamping difficulties due to insufficient distance between the bodies, and reduces operational jamming caused by arm interference. Second, the increase in distance 320 directly affects the initial width of the elastic clamping position 310—when it is necessary to clamp a large object, the bending structure increases the distance, allowing the elastic clamping position 310 to expand naturally, adapting to the object size without excessive force, and reducing the risk of object damage caused by forced clamping. On the other hand, the bending structure can be selected based on actual needs: a direct connection without bending can be used when gripping regular objects to ensure precise control of the gripping force; when gripping large objects or requiring a large operating space, the bending structure can be activated to achieve on-demand adjustment. Furthermore, the design of the bending angle can optimize the force transmission path, increasing the spacing while avoiding insufficient rigidity of the arm, ensuring that the gripping stability is not affected.

[0057] In some embodiments, at least one of the first gripping portion 130 and the second gripping portion 230 is provided with a flexible toothed layer so that when the medical forceps 300 is in a gripping state, the flexible toothed layer contacts the object being gripped. As an example, such as... Figure 9As shown, the first gripping part 130 is provided with a first flexible toothed layer 131, and the second gripping part 230 is provided with a second flexible toothed layer 231. When the medical forceps 300 is in the gripping state, the first flexible toothed layer 131 and the second flexible toothed layer 231 respectively contact the object being gripped, so as to apply pressure to the object being gripped when in contact with it, and undergo recoverable deformation to protect the object being gripped to a certain extent. This structural design, on the one hand, increases the friction between the toothed structure and the object being gripped, preventing slippage. For example, when gripping smooth electronic components or glassware, the flexible toothed layer can deform to conform to the surface of the object, enhancing the gripping firmness. On the other hand, the flexible material itself undergoes recoverable deformation, avoiding indentation or damage to the object caused by rigid gripping. For example, when gripping tissue during medical surgery, the flexible layer can reduce mechanical damage to fragile tissues while maintaining stable gripping. On the other hand, the hardness of the flexible layer can be adjusted according to the material of the object: a soft material is used when clamping precision components, while a hard-flexible material is used when clamping heavy objects, balancing protection and strength. Furthermore, the toothed design can adapt to objects with different surface shapes; whether flat, curved, or irregular, effective contact can be achieved through deformation.

[0058] In order to maintain the gripping state of the medical tweezers 300 on the object after it has been grasped, in some embodiments, such as Figure 4 or Figure 9As shown, between the protrusion and the first connecting portion 120, the first body 110 is provided with a protruding pin 111, and the second body 210 is provided with a limiting pin hole 211 corresponding to the pin 111. When the medical forceps 300 is in the clamping state, the pin 111 is configured to be inserted into and limited in the limiting pin hole 211. The limiting pin hole 211 is used to restrict the position of the pin 111. When the pin 111 is inserted into the limiting pin hole 211, if no external force is applied, such as the user not applying a separation force to the first body 110 and the second body 210, the limiting pin hole 211 will lock, hold, or clamp the pin 111, so that the pin 111 remains inserted into the limiting pin hole 211 and cannot be dislodged from the limiting pin hole 211 until the user applies force to pull the pin 111 out of the limiting pin hole 211. Taking surgical forceps as an example, after clamping biological tissue, the user can release their hand. The pin 111, in conjunction with the limiting pin hole 211, maintains the distance 320 between the first body 110 and the second body 210, thereby maintaining the width of the elastic clamping position 310 between the first gripping part 130 and the second gripping part 230, and thus maintaining the clamping state of the medical forceps 300 on the object being gripped. This structural design, on the one hand, allows the locking structure of the pin 111 and the limiting pin hole 211 to lock the distance 320 between the first body 110 and the second body 210 after clamping the object, keeping the elastic clamping position 310 at a fixed width. For example, after clamping biological tissue during medical surgery, the user does not need to continuously apply force to maintain the clamping state, reducing hand fatigue and facilitating long-term operation or collaboration with other instruments. On the other hand, the precise limiting of the pin 111 by the limiting pin hole 211 avoids changes in the distance 320 caused by hand tremors during clamping, ensuring uniform and stable clamping force. When gripping precision electronic components, the locking structure prevents damage or detachment due to fluctuations in force, while providing a stable gripping base for delicate operations such as welding and assembly. Furthermore, the pin 111 disengages from the limiting pin hole 211 only when the user applies force, ensuring the reliability of the gripping state and avoiding the risk of accidental unlocking. It also eliminates the need for continuous force application, freeing up the user's hand strength, making it particularly suitable for elderly operators or scenarios requiring frequent operation switching, thus reducing operational intensity. Moreover, through the mechanical locking design of the pin 111 and the limiting pin hole 211, the medical forceps 300 upgrades traditional continuous force gripping to one-time force locking, retaining the adaptive characteristics of the elastic gripping position 310 while improving operational stability and convenience through a rigid locking structure, demonstrating significant advantages in scenarios requiring long-term gripping or precise control.

[0059] Combination Figures 1 to 9In some embodiments, the medical forceps 300, such as surgical forceps, is a medical tool used to grasp and hold objects. It has two slightly curved and flexible branches, i.e., arms, and the working surfaces of these two branches, i.e., the parts used to grasp objects, are called gripping portions. As an example, the gripping portions are designed to be flexible like a sponge, forming sponge-like forceps tips to undergo slight deformation when grasping the object, thereby increasing the contact area and reducing pressure. At the distal end of the branches of the medical forceps 300, that is, near the gripping portion of the body, a pin 111 is provided that engages with a limiting pin hole 211 to allow the sponge-like working surfaces of the two gripping portions to fit together more tightly. At the proximal end of the branches, that is, near the user's hand, a protrusion design ensures that the two sponge-like forceps tips maintain a fixed distance.

[0060] As an example, the special feature of the medical forceps 300 is its simple mechanism for closing the two branches: one branch, namely the first arm 100, has a pin 111 on its inner surface, and the other branch, namely the second arm 200, has a corresponding hole, namely the limiting pin hole 211. A small, flexible fork, which can be made of fluoroplastic or other plastic, is inserted into the hole. Its inner diameter is exactly the same as the outer diameter of the pin 111, and this fork is secured by a washer outside the limiting pin hole 211. When the user squeezes the medical forceps 300, bringing the two sponge-like forceps tips closer together, the pin 111 will firmly insert into the small fork in the hole, keeping the two branches closed.

[0061] As an example, the structure that maintains a constant distance between the two sponge-like forceps tips is achieved through two pairs of protrusions, or two protrusions in total. These protrusions are extensions of the semi-circular portion of the outer surface of one branch, and they can mate well with the surface of the other branch, or with the protrusions on the surface of the other branch, or with the positioning portion on the surface of the other branch. One pair of protrusions is located on the part of the branch closest to where the user's hand begins to squeeze, and the other pair of protrusions is at the end of that part. In addition, the side of the sponge-like forceps tip used to grasp objects is designed with teeth and grooves, meshing like gears. These teeth and grooves are located on the inner surface of the gripping tip. When the user squeezes the medical forceps 300 forcefully, bringing the two gripping parts closer together, these teeth and grooves will mesh tightly together like gears.

[0062] It should be noted that other embodiments of this application also include medical forceps formed by combining the technical features of the above embodiments.

[0063] The technical features of the above embodiments can be combined in any way.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
