Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a staple remover for preventing staples from falling off. Background Art

[0002] Skin staples are widely used for suturing the surface skin of wounds and surgical incisions. After the wound has healed completely, doctors need to remove them. For this purpose, a staple remover has been created, which greatly improves the efficiency of staple removal.

[0003] A Chinese patent with the publication number CN 208973973U discloses a staple remover for removing skin staples, aiming to solve the problem of how to reduce the use cost of the staple remover. The staple remover for removing skin staples includes an upper handle, a U-shaped lower jaw, a lower handle, an upper tongue and a rotating shaft. The upper handle and the lower handle are hinged together through the rotating shaft. The U-shaped lower jaw is arranged at the front end of the upper handle, and the upper tongue is arranged at the front end of the lower handle. It also includes a jaw protection sleeve and a tongue protection sleeve, and the jaw protection sleeve and the tongue protection sleeve are respectively detachably sleeved on the U-shaped lower jaw and the upper tongue.

[0004] However, the above-mentioned staple remover has the following disadvantages: After the staple is removed by the staple remover, it often needs to be placed in a suitable container such as a kidney dish. However, during the process of clamping the staple by the staple remover, due to the relatively smooth outer surfaces of the jaw protection sleeve and the tongue protection sleeve, the staple is likely to slip during removal, which is likely to cause secondary injury to the wound. At the same time, it is likely to fall off during clamping and transfer, and there is an urgent need for improvement. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a staple remover for preventing staples from falling off, which improves the clamping stability of the staple during staple removal and effectively prevents the staple from accidentally detaching during the staple removal process.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A staple remover for preventing staples from falling off includes a first handle and a second handle. A rotating shaft is integrally provided on the front side wall of the second handle. The first handle is rotationally connected to the second handle through the rotating shaft. A first clamping member is provided at the front end of the first handle, and a second clamping member is provided at the front end of the second handle. The first clamping member and the second clamping member are arranged opposite to each other and are in clamping cooperation.

[0007] A pressing portion extends from the front end of the second clamping member, and an anti-detachment block extends from the end of the pressing portion. A clamping hole corresponding to the pressing portion is formed on the first clamping member. When the second clamping member and the first clamping member are in clamping cooperation, the pressing portion of the second clamping member passes through the clamping hole of the first clamping member and is in pressing cooperation with the staple, and the anti-detachment block is in anti-detachment cooperation with the staple.

[0008] By adopting the above technical solution, different from the way of using a separately arranged pin to achieve the hinge between two handles in the market, which is prone to the situation of pin detachment, the present utility model directly integrally fixes the rotating shaft on the side wall at the front end of the second handle, which can avoid the situation that the rotating shaft accidentally falls off and cannot be found; during the process of removing the staples, the first clamping member and the second clamping member can be controlled to clamp each other, so that the pressing portion bends the middle part of the staple, and the two sides of the staple are turned up relative to the middle to achieve staple removal. When the two ends of the staple are warped and clamped between the pressing portion and the clamping hole, the anti-detachment block is used to hook the staple to prevent the staple from detaching from the staple remover, which improves the clamping stability of the staple during staple removal of the present utility model and effectively prevents the accidental detachment of the staple during the staple removal process.

[0009] A further setting of the present utility model is that: the first clamping member includes a tongue inserting portion integrally arranged at its front end, and the clamping hole is opened on the tongue inserting portion.

[0010] By adopting the above technical solution, before staple removal, the tongue inserting portion can be pre-inserted into the gap between the staple and the skin surface, which is convenient for the subsequent quick clamping of the staple by the first clamping member and the second clamping member, thereby improving the disassembly efficiency of the staple by the present utility model.

[0011] A further setting of the present utility model is that: the width of the tongue inserting portion gradually decreases from the end close to the first clamping member to the end far from the first clamping member.

[0012] By adopting the above technical solution, the tongue inserting portion can be inserted into the gap between the staple and the patient's skin more smoothly and quickly.

[0013] A further setting of the present utility model is that: the front end face of the tongue inserting portion is set as an arc surface.

[0014] By adopting the above technical solution, the tongue inserting portion with an arc surface design at the front end face can effectively prevent the situation of skin puncture during the insertion process of the tongue inserting portion.

[0015] A further setting of the present utility model is that: the first clamping member includes mounting plates arranged in parallel on both sides, the first handle is communicated with an installation cavity and a limiting groove, the mounting plates on both sides are fixedly installed in the installation cavity, and the second clamping member is rotatably arranged between the mounting plates on both sides and can rotate in the limiting groove.

[0016] By adopting the above technical solution, the mounting plates arranged in parallel on both sides can improve the smoothness of the rotation of the first clamping member relative to the second clamping member, and the setting of the limiting groove can limit the rotation angle of the second clamping member relative to the first clamping member.

[0017] A further setting of the present utility model is that: the second clamping member further includes a fixing portion and a hinged portion located between the fixing portion and the pressing portion. The fixing portion is fixedly connected to the second handle. The hinged portion is provided with a through hole, and the hinged portion is rotatably connected to the rotating shaft through the through hole.

[0018] By adopting the above technical solution, the second clamping member is also rotatably connected to the rotating shaft, improving the concentricity of the rotation of the second clamping member.

[0019] A further setting of the present utility model is that: a clamping notch is formed between the hinged portion and the pressing portion. When the first clamping member and the second clamping member are clamped and matched, and the pressing portion passes through the clamping hole, the second clamping member is clamped and stopped in cooperation with the first clamping member through the clamping notch.

[0020] By adopting the above technical solution, when the first clamping member and the second clamping member are in contact and clamped with each other, the clamping notch and the edge of the clamping hole of the first clamping member are used for clamping, which can limit the clamping position between the first clamping member and the second clamping member, and improve the clamping stability between the first clamping member and the second clamping member.

[0021] A further setting of the present utility model is that: the side wall of the hinged portion close to the first clamping member is set as an arc surface.

[0022] By adopting the above technical solution, the design of the arc surface can make the first clamping member play an avoidance effect when rotating relative to the second clamping member, thereby improving the assembly compactness of the present utility model.

[0023] A further setting of the present utility model is that: a first positioning groove is formed on the upper end surface of the first clamping member, and a second positioning groove is correspondingly formed on the pressing portion opposite to the first positioning groove. When the second clamping member and the first clamping member are clamped and matched, the first positioning groove and the second positioning groove are in positioning cooperation with the suture nail.

[0024] By adopting the above technical solution, by using the positioning effect of the first positioning groove and the second positioning groove on the suture nail, when the first clamping member and the second clamping member are clamped with each other, the suture nail can always be kept in the first positioning groove and the second positioning groove, effectively preventing the suture nail from shifting during nail removal and causing wound strain.

[0025] A further setting of the present utility model is that: a limiting and buffering block is formed by two-color injection molding on the second handle. When the second clamping member and the first clamping member are clamped and matched, the second handle is in limiting and buffering cooperation with the first handle through the limiting and buffering block.

[0026] By adopting the above technical solution, the limiting buffer block formed by two-color injection molding can improve the connection firmness between it and the second handle. At the same time, when the first handle and the second handle are clamped with each other, the limiting buffer block can not only limit the clamping of the first handle and the second handle, but also effectively absorb energy and reduce vibration when the first handle and the second handle impact each other during clamping, achieving the purpose of buffering.

[0027] To sum up, the utility model has the following beneficial effects:

[0028] A rotating shaft is integrally arranged on the front side wall of the second handle, and the first handle is rotatably connected to the rotating shaft. At the same time, a first clamping member is fixedly connected to the front end of the first handle, and a second clamping member is fixedly connected to the front end of the second handle. A pressing portion extends from the front end of the second clamping member, and an anti-detachment block extends from the end of the pressing portion. A clamping hole is formed on the first clamping member. Different from the situation in the market where using a separately arranged pin to realize the hinge between two handles is likely to cause the pin to fall off, in the utility model, the rotating shaft is directly integrally fixed on the side wall of the front end of the second handle, which can avoid the situation that the rotating shaft accidentally falls off and cannot be found; and during the process of removing the suture nail, the first clamping member and the second clamping member can be controlled to clamp each other, so that the pressing portion bends the middle part of the suture nail, and the two sides of the suture nail are turned up relative to the middle to realize nail removal. When the two ends of the suture nail are upturned and clamped between the pressing portion and the clamping hole, and the anti-detachment block hooks the suture nail to prevent the suture nail from detaching from the nail removing forceps, which improves the clamping stability of the suture nail during nail removal in the utility model and effectively prevents the suture nail from accidentally detaching during the nail removal process.

[0037] The following further describes the present utility model with reference to the accompanying drawings. Specific Embodiment 1

[0039] A staple - removing pliers for preventing staple dropping, as Figure 1 and Figures 4 - 5 shown, includes a first handle 1 and a second handle 3. A rotating shaft 31 is integrally provided on the front - end side wall of the second handle 3. The first handle 1 is rotationally connected to the second handle 3 through the rotating shaft 31. A first clamping member 2 is provided at the front end of the first handle 1, and a second clamping member 4 is provided at the front end of the second handle 3. The first clamping member 2 and the second clamping member 4 are oppositely arranged and are in clamping cooperation; the front end of the second clamping member 4 extends with a pressing part 41, and the end of the pressing part 41 extends with an anti - detachment block 411. A clamping hole 2a corresponding to the pressing part 41 is opened on the first clamping member 2. When the second clamping member 4 and the first clamping member 2 are in clamping cooperation, the pressing part 41 of the second clamping member 4 passes through the clamping hole 2a of the first clamping member 2 and presses the staple in cooperation, and the anti - detachment block 411 is in anti - detachment cooperation with the staple; the first clamping member 2 includes installation plates 22 which are located on both sides and are parallel to each other. The first handle 1 is communicated with an installation cavity 1a and a limiting groove 1b. The two installation plates 22 are fixedly installed in the installation cavity 1a. The second clamping member 4 is rotatably arranged between the two installation plates 22 and can rotate in the limiting groove 1b. The two parallel installation plates 22 can improve the smoothness of the rotation of the first clamping member 2 relative to the second clamping member 4. The setting of the limiting groove 1b can limit the rotation angle of the second clamping member 4 relative to the first clamping member 2; a first positioning installation groove 1c is opened on the inner side wall of the installation cavity 1a of the first handle 1, and one end of the first clamping member 2 is non - rotatably installed in the first positioning installation groove 1c. A second positioning installation groove 3a is opened on the side wall of the second handle 3, and one end of the second clamping member 4 is non - rotatably installed in the second positioning installation groove 3a.

[0040] As Figures 1 - 2As shown, the first clamping member 2 includes a tongue insertion portion 21 integrally provided at its front end. A clamping hole 2a is formed in the tongue insertion portion 21. Before removing the staple, the tongue insertion portion 21 can be pre-inserted into the gap between the staple and the skin surface, facilitating the subsequent rapid clamping of the staple by the first clamping member 2 and the second clamping member 4, thereby improving the disassembly efficiency of the staple by the present utility model. The width of the tongue insertion portion 21 gradually decreases from the end close to the first clamping member 2 towards the end away from the first clamping member 2, enabling the tongue insertion portion 21 to be inserted more smoothly and quickly into the gap between the staple and the patient's skin. The front end face of the tongue insertion portion 21 is provided as an arc surface. The tongue insertion portion 21 with an arc surface design at the front end face can effectively prevent the skin from being punctured during the insertion of the tongue insertion portion 21.

[0041] As Figures 3 - 5 shown, the second clamping member 4 further includes a fixing portion 42 and a hinge portion 43 located between the fixing portion 42 and the pressing portion 41. The fixing portion 42 is fixedly connected to the second handle 3. A through hole 43a is formed in the hinge portion 43, and the hinge portion 43 is rotatably connected to the rotating shaft 31 through the through hole 43a, enabling the second clamping member 4 to be rotatably connected to the rotating shaft 31 as well, improving the concentricity of the rotation of the second clamping member 4. A clamping notch 4a is formed between the hinge portion 43 and the pressing portion 41. When the first clamping member 2 and the second clamping member 4 are clamped and matched, and the pressing portion 41 passes through the clamping hole 2a, the second clamping member 4 is in clamping and stopping cooperation with the first clamping member 2 through the clamping notch 4a. When the first clamping member 2 and the second clamping member 4 come into contact and clamp each other, the clamping effect between the clamping notch 4a and the edge of the clamping hole 2a of the first clamping member 2 can limit the clamping position between the first clamping member 2 and the second clamping member 4, improving the clamping stability between the first clamping member 2 and the second clamping member 4. The side wall of the hinge portion 43 close to the first clamping member 2 is provided as an arc surface. The arc surface design can achieve an avoidance effect when the first clamping member 2 rotates relative to the second clamping member 4, thereby improving the assembly compactness of the present utility model. In this embodiment, the first clamping member 2 is provided with a through hole 2b corresponding to the rotating shaft 31, and one side of the through hole 2b communicates with the edge of the first clamping member 2. When one end of the first clamping member 2 is inserted and fixedly installed in the first positioning installation groove 1c of the first handle 1, the rotating shaft 31 can be directly snapped into the through hole 2b from the edge of the first clamping member 2, facilitating the installation of the rotating shaft 31 on the first clamping member 2.

[0042] The basic working principle of the utility model is as follows: a rotating shaft 31 is integrally arranged on the front end side wall of the second handle 3, the first handle 1 is rotatably connected to the rotating shaft 31, and at the same time, the first clamping member 2 is fixedly connected to the front end of the first handle 1, and the second clamping member 4 is fixedly connected to the front end of the second handle 3. A pressing portion 41 extends from the front end of the second clamping member 4, and an anti-dropping block 411 extends from the end of the pressing portion 41. A clamping hole 2a is provided on the first clamping member 2. Different from the method of realizing the hinge connection between the two handles by using a separately arranged pin on the market, which easily causes the pin to fall off, the utility model directly and integrally fixes the rotating shaft 31 on the second handle 3, the rotating shaft 31 can be prevented from accidentally falling off and being unable to be found; and in the process of removing the suture nail, the first clamping member 2 and the second clamping member 4 can be controlled to clamp each other, so that the pressing portion 41 bends the middle part of the suture nail, so that the two sides of the suture nail are folded upward relative to the middle to realize the suture nail removal, when the two ends of the suture nail are tilted and clamped between the pressing portion 41 and the clamping hole 2a, and the anti-slip block 411 is used to hook the suture nail to prevent the suture nail from being detached from the nail removal pliers, which improves the clamping stability of the suture nail during the suture nail removal and effectively prevents the suture nail from accidentally detaching during the suture nail removal process. Specific embodiment 2

[0044] A nail removal pliers for preventing nails from falling, such as Figures 6 - 7 As shown, the difference between this embodiment and the specific embodiment 1 is that: the first clamping member 2 has a first positioning groove 2C on its upper end surface, and the pressing portion 41 has a second positioning groove 41a corresponding to the first positioning groove 2C. When the second clamping member 4 and the first clamping member 2 are clamped together, the first positioning groove 2C and the second positioning groove 41a are positioned and matched with the suture nail. The first positioning groove 2C and the second positioning groove 41a are used to position the suture nail, so that when the first clamping member 2 and the second clamping member 4 are clamped together, the suture nail can always be kept in the first positioning groove 2C and the second positioning groove 41a, which can effectively prevent the suture nail from being offset when the nail is removed to cause injury. The second handle 3 is provided with a limit buffer block 32 by double-color injection molding. When the second clamping member 4 and the first clamping member 2 are clamped and matched, the second handle 3 is limited and buffered with the first handle 1 through the limit buffer block 32. The limit buffer block 32 formed by double-color injection molding can improve the firmness of the connection between it and the second handle 3. At the same time, when the first handle 1 and the second handle 3 are clamped with each other, the limit buffer block 32 can not only limit the clamping of the first handle 1 and the second handle 3, but also effectively absorb energy and reduce shock when the first handle 1 and the second handle 3 collide with each other, thereby achieving the purpose of buffering.

[0045] The other structures of this embodiment are the same as those of the first embodiment and will not be described again.

[0046] The above are only the preferred embodiments of the present utility model. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present utility model are included in the scope of the patent application of the present utility model.
