Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical forceps with a detachable head. Background Technology

[0002] Medical forceps typically consist of a pair of overlapping blades at their tails, generally made of stainless steel, ABS, or polyethylene, and are used to hold tissues, instruments, dressings, etc. According to searches on the website of the National Medical Products Administration and research and analysis of existing medical forceps on the market, apart from a few special types, the main differences between forceps used for different purposes lie in the design of the forceps head, aside from slight variations in length. For example, based on the shape of the head, there are straight forceps and curved forceps; based on the structure of the lip anastomosis, there are lip teeth, lip hooks (1 / 2 hook, 2 / 3 hook, 3 / 4 hook, etc.), and flat forceps (without lip teeth or lip hooks); in addition, the width of the forceps head and the shape of the tip also vary depending on the application. Providing a complete set of all types of medical forceps would be costly.

[0003] Furthermore, in practical use, the most easily damaged part of the forceps is the forceps head. Collisions between instruments, gripping hard objects, and prolonged use can all cause damage to the forceps head's teeth or hooks, cracks, or loss of fit. To ensure safety, the instruction manual clearly requires that the head of medical forceps be regularly inspected for defects, cracks, or other damage to maintain its gripping performance. Damaged forceps should be discarded; one-piece medical forceps result in significant waste and may cause environmental pollution during recycling. Utility Model Content

[0009] The locking device comprises two parts, with each of the two tweezer tips locked to the two tweezer handles by the two locking devices. The locking devices are slidably disposed on the tweezer handles along their length. The front end of the locking device is provided with a slot. When the locking neck of the locking protrusion extends from the other side, the locking device slides forward along the length of the tweezer handle, causing the slot to engage at the locking neck to lock the locking protrusion and the tweezer tips on the tweezer handles.

[0010] Preferably, the protrusion can extend into the inside of the through hole and protrude outward; the locking device is slidably disposed on the outside of the tweezer handle.

[0011] Preferably, the locking device has an anti-slip structure on the surface away from the tweezer handle.

[0012] Preferably, the tweezers handle is provided with a sliding hole extending along the length of the tweezers handle, and a sliding post is provided on one side of the locking device, the sliding post being slidably disposed in the sliding hole.

[0013] Preferably, the two tweezer handles are an integral structure.

[0014] Preferably, the through hole is a round hole.

[0015] Preferably, the slot is a V-shaped slot or a U-shaped slot.

[0016] Preferably, a first toothed structure is provided on the inner walls of both sides of the sliding hole in the width direction, and a second toothed structure is provided on the surface of the sliding column that can contact the inner walls of both sides of the sliding hole in the width direction.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this invention is to provide a medical forceps with a detachable head to solve the problems existing in the prior art and reduce replacement costs and medical costs.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0035] Example 1

[0036] This utility model provides a medical forceps with a detachable head, such as Figures 1-5 As shown, it includes: tweezer handles 1, tweezer heads 3, and locking devices 2. Two tweezer handles 1 are provided, with their rear ends fixedly connected, and their front ends able to move closer together or further apart; each tweezer handle 1 has a through hole 5 penetrating its inner and outer surfaces at its front end; two tweezer heads 3 are provided, with a locking protrusion 4 at their rear end; the locking protrusion 4 can extend into one side of the through hole 5 and protrude out the other side; the portion of the locking protrusion 4 that protrudes out of the through hole 5 has a locking neck; two locking devices 2 are provided, with each tweezer head 3 locked to one tweezer handle 1 by the two locking devices 2 respectively. The locking devices 2 are slidably mounted on the tweezer handle 1 along its length; the front end of the locking device 2 has a locking groove 8. When the locking neck of the locking protrusion 4 protrudes out the other side, when the locking device 2 slides forward along the length of the tweezer handle 1, the locking groove 8 can engage with the locking neck to lock the locking protrusion 4 and the tweezer heads 3 onto the tweezer handle 1.

[0037] The necking refers to a section of a columnar structure whose surface is recessed inward to form an annular groove extending along the axial direction of the columnar structure.

[0038] The forceps head 3 of the medical forceps provided by this utility model is detachable. Therefore, when the forceps head 3 is damaged or does not meet the requirements for use, in order to ensure the safety of use, the forceps head 3 can be removed separately and replaced with a new forceps head 3. The forceps handle 1 can be reused, thereby reducing replacement costs, reducing waste of resources, and reducing environmental pollution. In addition, when it is necessary to change the type of forceps head 3, the original forceps head 3 on the forceps handle 1 can be removed and replaced with the required type of forceps head 3. Therefore, in practical applications, it is not necessary to equip a set of medical forceps of each structure. Only forceps heads of different structures need to be equipped, thereby reducing the cost of use and medical costs.

[0039] When it is necessary to install the tweezers head 3 on the tweezers handle 1, the locking protrusion 4 at the rear end of the tweezers head 3 is inserted into one side of the through hole 5 and extended out from the other side. Then, the locking device 2 is slid forward so that the slot 8 on the locking device 2 is engaged at the lock neck to lock the locking protrusion 4 and the tweezers head 3 on the tweezers handle 1. When it is necessary to replace the tweezers head 3, the locking device 2 is manually moved backward so that the slot 8 is away from the locking protrusion 4 to unlock the locking protrusion 4 and the tweezers head 3. Then the original tweezers head 3 on the tweezers handle 1 can be removed, and then the above process of installing the tweezers head 3 can be performed.

[0040] In some embodiments, the cam 4 can extend into the inside of the through hole 5 and protrude outward; the locking device 2 is slidably disposed on the outside of the tweezer handle 1.

[0041] In this embodiment, the locking protrusion 4 extends into the through hole 5 from the inside and extends out from the outside. It can be understood that the rear end of the tweezers head 3 is located inside the tweezers handle 1. With this configuration, when a clamping force is applied, the tweezers handle 1 can transmit the clamping force to the tweezers head 3 through its own front end structure. The locking protrusion 4 only serves to lock the tweezers head 3 to the tweezers handle 1. In other words, compared to the embodiment where the locking protrusion 4 extends into the through hole 5 from the outside and extends out from the inside, this embodiment of the invention results in less stress on the locking protrusion 4, thereby extending the service life of the tweezers head 3.

[0042] In some embodiments, the locking device has an anti-slip structure 9 on the surface away from the tweezer handle 1.

[0043] This embodiment facilitates the use of the forceps handle 1 by medical personnel. The anti-slip structure 9 can be of various types, such as anti-slip texture, handle pattern, or anti-slip bumps.

[0044] In some embodiments, the tweezer handle 1 is provided with a sliding hole 6 extending along the length direction of the tweezer handle 1, and a sliding post 7 is provided on one side of the locking device 2, the sliding post 7 being slidably disposed in the sliding hole 6.

[0045] This embodiment provides a specific method for sliding connection between the locking device 2 and the tweezer handle 1. In a specific example, multiple sliding holes 6 can be provided on each tweezer handle 1. Correspondingly, the number of sliding pins 7 on the locking device 2 must be the same as the number of sliding holes 6 on each tweezer handle 1, and their positions must correspond. In this way, the stability of sliding can be increased. In a more specific example, the end of the sliding pin 7 away from the locking device 2 extends from the inside of the sliding hole 6, and the width of the extended part is greater than the width of the sliding hole 6. This can prevent the sliding pin 7 from coming out of the sliding hole 6, thereby preventing the locking device 2 from falling off the tweezer handle 1.

[0046] In some embodiments, the two tweezer handles 1 are an integral structure.

[0047] The integrated tweezer handle 1 in this embodiment has good structural stability.

[0048] In some embodiments, the through hole 5 is a round hole, a square hole, or an irregular hole. Correspondingly, the cross-sectional shape of the protrusion 4 needs to match the cross-sectional shape of the through hole 5, but its size should be slightly smaller than that of the through hole 5. Of course, in extreme cases, the cross-sectional shape and size of the protrusion 4 are the same as those of the through hole 5. In this way, when the protrusion 4 is installed in the through hole 5, the gap between the protrusion 4 and the through hole 5 is infinitely close to zero, thereby reducing the shaking of the tweezers 3 relative to the tweezers handle 1.

[0049] In some embodiments, the slot 8 is a V-shaped slot or a U-shaped slot. It is understood that the shape of the slot 8 is only similar to a V-shaped slot or a U-shaped slot.

[0050] In some embodiments, a first toothed structure is provided on the inner walls of both sides of the sliding hole 6 in the width direction, and a second toothed structure is provided on the surface of the sliding column 7 that can contact the inner walls of both sides of the sliding hole 6 in the width direction. The first toothed structure and the second toothed structure cooperate to hinder but allow the sliding column 7 to slide in the sliding hole 6.

[0051] The solution provided by this embodiment allows the locking device 2 to slide on the tweezer handle 1 only when pushed by an external force. Without the action of an external force, the sliding column 7 will have difficulty sliding in the sliding hole 6 due to the obstruction of the first tooth structure, thereby playing a certain locking role for the locking device 2 and improving the stability of use.

[0052] In some embodiments, the tweezers 3 are provided in various ways, and the structures and sizes of the various tweezers 3 are not exactly the same.

[0053] This embodiment allows medical staff to easily replace different types of forceps 3 to deal with different patients' conditions, improving the flexibility of the device's use.

[0054] In some embodiments, the tweezer handle 1, the tweezer head 3, and the locking device 2 are all made of metal.

[0055] The metal material used in this embodiment is to facilitate disinfection after a single use.

[0056] Example 2

[0057] This utility model embodiment provides another type of medical forceps with a detachable head, such as... Figure 6 and Figure 7 As shown, unlike Embodiment 1, this application abandons the toothed structure used in Embodiment 1 to lock the position of the locking device 2. Instead, the size of the front opening of the slot 8 is set to be 0.5mm to 1mm smaller than the size of the lock neck. In this way, when in use, after the protrusion 4 is inserted into the inside of the through hole 5 and extended outward, the locking device 2 is pushed forward. When the front opening of the slot 8 abuts against the neck of the protrusion 4, the pushing force is increased, which can make the front opening slightly expand and lock into the neck. At this point, the installation of the tweezers 3 is completed. Since the front opening of the slot 8 is slightly smaller than the neck, the neck will not come out of the slot 8 during normal use. When it is necessary to remove the tweezers 3, the locking device 2 is pushed backward, which can move the slot 8 away from the protrusion 4, thereby achieving the purpose of the protrusion 4 coming out of the slot 8.

[0058] In addition, when using the device to hold an object, medical staff can manually limit the locking device 2 when holding the tweezers handle 1, thereby preventing the tweezers head 3 from falling off due to the locking device 2 slipping backward.

[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
